　　This year is a highlight year in the history of marathon. On October 12, Kenyan male athlete Kipkog broke the human limit in Vienna and successfully ran into the two-hour marathon. On October 13th, Kenyan woman Bridget Koschi broke the world best result in the women’s marathon, which has been maintained for 16 years, in Chicago. In the 39th Beijing Marathon, which ended on November 3rd, the men’s race record was also refreshed again.

　　In recent years, the number of marathon events and various road running events has been blowout. With the participation of more and more people, road running has gradually become an urban culture that leads the national fitness trend.

　　According to the Business Value Report of Sports Industry in China, among the sports that people often participate in, running ranks among the best with 43% participation. Road running, represented by marathon, has become one of China people’s favorite fitness exercises and an important platform for national fitness. In 2018, the total number of participants in the national marathon and related events was 5.83 million, an increase of 4.33 million over 2015.

　　A group of statistics released by IAAF on amateur runners and runners around the world in June this year show that in the past 10 years, only about 12% of all runners took part in marathon (marathon duration is 42.195 kilometers), while the number of people who took part in half marathon (hereinafter referred to as "half horse") kept increasing, accounting for about 30%. The "5 km" has the largest number of participants, accounting for about 35% of all runners. In China, the scale of road runners is also growing.

　　So "5 km", "10 km", "half horse" and "whole horse", which event is suitable for you and how to run healthier? On November 2nd, more than 50 people, including leaders of more than 20 national road running/marathon trade associations and runners from Beijing, Inner Mongolia, Anhui, Jilin, Hebei, Jiangsu, Shandong, Shanxi, Shaanxi and Jiangxi, gathered in Beijing to participate in the symposium on "Marathon and Great Health" jointly held by "Healthy China" edition of China Youth Daily and Beijing Marathon Association. Participants discussed the relationship between road running and personal health, marathon and industry health, and marathon and social health atmosphere from the perspectives of education, medicine, media communication and the development of road running industry, so as to convey the concept of scientific fitness to fitness enthusiasts.

　　Marathon is an extreme sport, and every participant should treat it with caution.

　　There are probably the following motivations for people to participate in road running: at the physiological level, in order to keep healthy or lose weight; On the psychological level, in order to increase self-confidence, pursue the meaning of life and cope with negative emotions, gain a sense of accomplishment in competing with others and achieving personal goals; At the social level, I hope to associate with others and get recognition.

　　From illness to running 59 marathons (including 22 "all horses"), Wen Caifeng, a runner over 50 years old, started running for health. Because of encephalitis, she was once "immune" in college. After graduation, she went from sub-health to minor illness, and then she was hospitalized almost every year. Wen Caifeng realized that hospitals can only treat diseases and only exercise can make herself healthy, so she started running and ran into the marathon. Wen Caifeng’s running goal for himself is "no injury, longer, faster and healthier".

　　How to know the marathon, and what are the misunderstandings of the public about the marathon? Zhao Fuming, president of Beijing Marathon Association, said that people who never run talk about "horses", while some enthusiasts will excessively pursue personal best (PB). "First of all, we should realize that as amateur runners, we are far away from competitive sports. Even those who have the best performance among runners should also realize the gap and not aim too high; Secondly, it should be Do not forget your initiative mind. When running, ensuring health is the top priority, without affecting normal work and life, scientific fitness, and enjoying a healthier life through exercise. " Zhao Fuming believes that the marathon itself is an extreme sport, and every participant should be treated with caution.

　　Sports medicine experts teach you how to run safer.

　　Zhu Jingxian, a medical supervisor and sports physician in Peking University Institute of Sports Medicine, started with the case of sudden death in a marathon and analyzed who was not suitable for running a marathon. She warned everyone to run scientifically and safely, and to keep running for health.

　　"Marathon is a typical extreme challenge project, and its first finisher died suddenly at the finish line, which is enough to show us the risks of this sport. However, it is also a sport full of challenges and enjoyment. Regular running will make the brain secrete more dopamine and endorphins, which will make people happy and even ‘ Addiction ’ 。” Zhu Jingxian said.

　　According to incomplete statistics, since 2014, more than 20 runners in China have died suddenly in the "Half Horse" or "All Horse" race or after the race. Foreign literature statistics show that the incidence of sudden death in marathon is 0.6/100,000-1.9/100,000, while in China, the incidence of sudden cardiac death in the whole population is 41.84/100,000, which is much higher than that in horse racing. Zhu Jingxian believes that "we can do more work to further avoid tragedies, and nip in the bud is the key."

　　Zhu Jingxian said that people with cardiopulmonary diseases and potential heart diseases are not recommended to participate in the competition. How to find potential heart diseases, such as congenital heart disease and hypertrophic cardiomyopathy, is the key to reduce sudden cardiac death during or after the game. "We suggest that the contestants go to a regular hospital for the following examinations before the competition: electrocardiogram, echocardiography and cardiopulmonary exercise experiment. Physical examination before the game is very important. " Zhu Jingxian said.

　　Secondly, the contestants need to run step by step before the race, and regular running habits are the basis to ensure the completion of the marathon. "Generally speaking, people who have never run for a long distance, even if their physical fitness is good, are not recommended to participate in the marathon. For the first time, a strange sports event is prone to sports rhabdomyolysis, and in severe cases, renal failure may occur. " Zhu Jingxian said that for the first-time marathon runners, only after completing the running training equivalent to the whole marathon distance before the competition can they better play their level in the official competition, and at the same time reduce the risks of sports injuries and sudden death. Amateur masters who have participated in many marathons should also be careful not to blindly pursue achievements. "You should pay attention to your feelings in the race. If you are unwell, stop the race in time and seek medical support. If you stay up late, catch a cold and are in poor health before the game, it is recommended to give up the game. "

　　"The most prone to cardiac arrest is the runner whose pace (a concept often used in marathon training, which refers to the time required for a runner to run 1 kilometer) is between 5 minutes and 6 minutes and 30 seconds, that is, ‘ Quanma ’ The competition takes 3.5 -4.5 hours ‘ Amateur master ’ . 52% of cardiac arrest occurred in the last 10 kilometers of the marathon. " Zhu Jingxian said.

　　The common sports injuries in running are mostly concentrated in hips, knees and ankles. Dr. Zhu reminded runners to do what they can. "For short-term injuries, they can be cured through rest and physical compensation; Reversible long-term damage can be cured by drug therapy+physical factor therapy+rehabilitation training; However, for irreversible long-term damage, surgery is needed, and it may also cause permanent functional loss. "

　　Dr. Zhu Jingxian reminded runners: nutritional supplements at ordinary times, before, during and after the game should be paid enough attention; Running equipment should be based on ensuring safety, and it is not expensive to be right. Finally, she particularly emphasized that muscle strength training is very important for runners. "Muscle strength is the armor that protects joints and the cornerstone of PB."

　　The road running industry is in its infancy and full of opportunities.

　　Zhu Donghui, secretary of the Party Committee of Beijing No.3 Middle School, is also a marathon runner. Together with the headmaster of No.3 Middle School who is also a runner, he has formed a 70-person teachers’ running group and has participated in several events organized by Beijing Marathon Association. At the same time, the school also designed a 3 km -10 km running training plan for students of different ages. "The sense of accomplishment of students holding special medals after the game is more effective than any kind of verbal mobilization. It is our ultimate goal to cultivate students’ healthy habits through the guidance of teachers. Running is a lifelong benefit, and I believe that running students can also influence parents and friends around them. " Zhu Donghui said.

　　Road running industry associations and various running groups all over the country are grass-roots organizations that undertake and lead the vast number of road running people. Zhao Fuming believes that at present, the road running industry is in its infancy and has good development opportunities.

　　In this year’s National Day mass parade, Beijing Marathon Association organized more than 200 members to participate in the first set-up running group phalanx. Up to now, Beijing Marathon Association has hosted, undertaken and co-organized 13 events, conducted 1,140 public welfare trainings and 20 certification trainings, with about 58,000 participants, covering the Beijing-Tianjin-Hebei region.

　　How should local trade associations achieve healthy development? Zhao Fuming believes that the nature and positioning of industry associations should be clarified; Form a work team with common goals; Implement valuable work items; In line with the national strategy of healthy China, it is the key to actively cooperate with government policies and requirements.

　　Create a social atmosphere of scientific movement and healthy life

　　Hou Pengcheng, director of the Beijing Sports Federation Office, said that one of the functions of the Beijing Sports Federation is to strengthen the function of social organizations to lead the national fitness and activate the vitality of social organizations. As the organizer of the half-horse race in Beijing Park, the Beijing Sports Association is most concerned about the running safety and the health problems caused by it. The social atmosphere of healthy running is created by every runner. "The theme of this conference is to make scientific fitness the top priority in every runner’s mind. Don’t just throw yourself into a sport with cool fashion or beautiful equipment, but slowly integrate into it on the basis of fully understanding the risks, advantages and disadvantages of the project."

　　Hou Pengcheng suggested that runners should be responsible for their own health, combine their own characteristics and learn from others’ experience in running, and form the habit of lifelong exercise.

　　Xu Zhengbiao, deputy head of Huai ‘an Running Group in Jiangsu Province, and Lei Huashou, chairman of Nanchang Athletics Association, shared local experience in carrying out activities at the meeting. Cen Chuanli, honorary president of Beijing Marathon Association and former editor-in-chief of CCTV Sports Channel, made an analysis from the perspective of media promotion of running and great health. He thought, "Create a ‘ Scientific movement and healthy life ’ A good atmosphere is the responsibility of the media to serve the public. "

　　Since the beginning of this year, China’s foreign trade has withstood the pressure and shown strong resilience: in the first 11 months, the total import and export value of goods trade was 37.96 trillion yuan, achieving positive growth year-on-year for two consecutive months, and the stabilization trend continued to consolidate.

　　As one of the "Troika" driving economic growth, foreign trade plays an important role in driving consumption, expanding employment and promoting economic growth.

　　In 2018 and 2022, the scale of foreign trade has successively passed the 30 trillion yuan and 40 trillion yuan mark. Since 2017, it has maintained its position as the largest country in goods trade for six consecutive years, and the trade volume of goods with countries that jointly built the "Belt and Road" has increased by 8% annually & hellip; … Since the new era, China’s foreign trade development has continuously achieved new breakthroughs.

　　"It is necessary to speed up the transition from a big trading country to a strong trading country, consolidate the traditional advantages of foreign trade, cultivate new competitive advantages, expand the development space of foreign trade and actively expand imports." On December 5, 2014, during the 19th collective study in the Political Bureau of the Communist Party of China (CPC) Central Committee, the important exposition of the Supreme Leader General Secretary pointed out the direction for promoting the high-quality development of foreign trade.

　　Since the new era, China’s position in global trade has improved significantly — —

　　During the decade from 2013 to 2022, a series of data confirmed the solid pace of China’s foreign trade development: in 2020, the total trade in goods and services surpassed the United States for the first time and became the largest trading country in the world; The import and export scale of cross-border e-commerce in China has increased from 1 trillion yuan in 2018 to 2 trillion yuan in 2022, entering a period of rapid development; In 2022, the international market share of exports further increased to 14.7%, ranking first in the world for 14 consecutive years … …

　　"The steadily expanding scale, continuously optimized structure and increasing international market share all confirm that the high-quality development of China’s foreign trade is fast and steady." Zhuang Rui, Executive Dean of university of international business and economics Institute of International Economics, said that China is advancing from a big trading country to a powerful trading country, which has provided strong support for stabilizing the macro-economic market.

　　The quality and efficiency of China’s foreign trade have been continuously improved, and new kinetic energy has been continuously released — —

　　The just-concluded Central Economic Work Conference clearly pointed out that it is necessary to speed up the cultivation of new kinetic energy of foreign trade, consolidate the basic disk of foreign trade and foreign capital, and expand intermediate trade, service trade, digital trade and cross-border e-commerce export.

　　In recent years, the "new three kinds" represented by electric manned vehicles, solar cells and lithium batteries have become hot words in the field of foreign trade, and they are the representatives of accelerating the upgrading of foreign trade. In 2022, the export growth rate of China’s electric manned vehicles, solar cells, lithium batteries and other green and low-carbon products all exceeded 60%, and the new export kinetic energy grew rapidly.

　　Since the new era, the vitality of China’s foreign trade entities has been effectively stimulated by accelerating reform and innovation, smoothing logistics channels, continuously optimizing the business environment at ports, and increasing support for small and medium-sized enterprises. In 2022, the number of foreign trade enterprises with import and export performance increased by 5.6% over the previous year. Among them, private enterprises gradually grew into the "main force" of foreign trade, accounting for more than half of the annual import and export scale for the first time, and contributing 80.8% to China’s foreign trade growth.

　　China’s foreign trade "friend circle" has been further expanded — —

　　In addition to maintaining close ties with traditional market trading partners, China is also actively exploring emerging markets such as ASEAN, Africa, Latin America and Central Asia. From 2013 to October 2023, the total import and export volume of China and the countries that jointly built the "Belt and Road" exceeded 21 trillion US dollars. Among them, in terms of RMB, China’s import and export to co-construction countries increased by 19.4% year-on-year in 2022, accounting for 32.9% of China’s total foreign trade value, up by 3.2 percentage points; Imports and exports to other member countries of the Regional Comprehensive Economic Partnership Agreement (RCEP) increased by 7.5% year-on-year; Exports to Africa and Latin America increased by 14.8% and 14.1% respectively.

　　Zhang Yu, director of the International Economic and Trade Research Office of the Institute of Finance and Economics of China Academy of Social Sciences, said that while adhering to a high level of opening up, the effective implementation of RCEP and the continuous expansion of the "Belt and Road" and "friends circle" have opened up new space for deepening foreign trade development. In addition, international economic and trade events including Service Trade Fair, Consumer Expo, Canton Fair and China International Import Expo(CIIE) have also opened new channels for foreign trade transformation and upgrading.

　　At present, the external environment is turbulent, economic factors and non-economic factors are intertwined, and China’s foreign trade development still faces many difficulties and challenges. In response to this situation, China has continuously strengthened top-level design and continuously improved its foreign trade policy system.

　　The General Office of the State Council has successively issued a series of important documents, such as Implementation Opinions on Promoting the Innovative Development of Foreign Trade, Opinions on Promoting the Stable Scale and Excellent Structure of Foreign Trade, and Several Measures on Accelerating the Integrated Development of Domestic and Foreign Trade, which further clarified the path and direction for cultivating new formats, building a platform system, deepening reform and opening up, and creating a legalized, international and convenient trade environment.

　　Zhuang Rui said: China’s foreign trade and industrial fields are constantly advancing in system innovation, scientific and technological innovation, mode innovation and format innovation. Under this background, it is very important to deepen the domestic market and explore the international market to further improve the quality and efficiency of foreign trade. Facing the complicated and severe international situation, China should give full play to the positive role of foreign trade in building a new development pattern and bring more warmth and dividends to the world economy.

　　Yesterday was the deadline set by the International Olympic Committee for athletes to register for the Beijing Olympic Games. With the arrival of this date, the list of players in some events of "China Legion" has been announced one after another. An official of the State Sports General Administration revealed that the list of China sports delegation will be announced on July 25th, when the inaugural meeting of China delegation will be held.

　　What are the mysteries in the list of some projects that have been announced so far?

　　Men’s Football Team: "Dui Trace" is dying out.

　　Yesterday was the deadline for national men’s soccer teams to report to FIFA the list of 18 people who will eventually participate in the Olympic Games. Zhu Ting, Shen Longyuan, Zhang Lu and Lin Dai were finally voted out of the list of 18 contestants.

　　Some time ago, the Olympic team had just arrived in Changchun for training and had finalized a list of "18+4". At that time, in this list, the four players who became substitutes were Zhao Xuri, Hao Junmin, Lin Dai and Liu Zhenli. At that time, Dewey still had the command of the Olympic team’s training and competition, so Dewey naturally participated in the formulation of this "18+4" list. However, the original "18+4" list began to change subtly after Dewey left. After the warm-up match between the Olympic team and the Australian Olympic team last Sunday, it directly led to the adjustment of the list. In that warm-up match, Hao Junmin not only got the starting opportunity, but also performed well. Although Zhao Xuri came off the bench, he scored the only goal. Their status made the coaching staff finally decide to put them back on the 18-person list.

　　In the position of goalkeeper, Zhang Lu and Liu Zhenli are both substitutes, and their strength is similar. In the end, the coaching staff decided to keep Liu Zhenli in the 18-man list and eliminated Zhang Lu from the perspective of his richer experience in the Super League. Although there are rumors that Wang Yongpo, Mao Jianqing and others have returned to the Olympic team, according to the rules of the Olympic football competition, except for the "tragedies" like Hai and Qu Feifei, the doors of Wang Yongpo and Mao Jianqing’s return to the Olympic team have been completely closed.

　　After Hao Junmin and Zhao Xuri re-entered the 18-man list, which two players to choose as substitutes was a headache for the Olympic coaching staff. However, judging from the details that Shen Longyuan came off the bench in the second half of the China-Australia War but was replaced before the end of the game, the outside world has already noticed that Shen Yuanlong’s situation is very dangerous. Sure enough, Shen Longyuan was finally excluded from the list of 18 people. There are two reasons for his defeat: one is that he is injured at present, which affects the recovery of his state; Secondly, his position is relatively simple, and he can only play right avant-garde.

　　As for Zhu Ting, in the "Duy era", he was an absolute main force in both the Olympic team and the national team. However, through the top 20 matches of the national football team, almost everyone saw Zhu Ting’s weakness-he can only run but not score goals. In the last two warm-up matches of the Olympic team, Zhu Ting has stopped playing, and it is not surprising that Zhu Ting lost the election this time. However, the defeat of Zhu Ting and Shen Longyuan, two love generals of Dewey, will make people feel that the Olympic team is deliberately cleaning the traces left by Dewey.

　　List of 18 members of China Olympic team

　　Goalkeepers: Shengjiong Qiu and Liu Zhenli.

　　Defenders: Li Weifeng, Yuan Weiwei, Feng Xiaoting, Wan Houliang, Tan Wangsong and Lv Jianjun.

　　Midfielders: Zheng Zhi, Zhao Xuri, Zhou Haibin, Kelvin Cui, Hao Junmin and Chen Tao.

　　Forward: Jiang Ning, Han Peng, Dong Fangzhuo and Gao Lin.

　　List of four substitutes:

　　Shen Longyuan, Zhu Ting, Lin Dai, Zhang Lu

　　Women’s Football Team: Guangdong’s Xie Caixia was lucky to be shortlisted.

　　On July 21st, the day after China beat New Zealand 1-0 in the warm-up match, the 22-member list of China women’s football team participating in the Olympic Games was announced in advance. Because Qu Feifei was seriously injured in the Sino-Singapore warm-up match, the big list changed slightly. Five players, Liu Yali, Song Xiaoli, Lou Xiaoxu, Wei Xiaofen and Qu Feifei, left the team, while veteran Xie Caixia from Guangdong was lucky to stay in the 22-player list.

　　Xie Caixia, a 32-year-old, didn’t play much in the recent warm-up match of China women’s football team. However, due to Qu Feifei’s fractured fibula in her left leg, she dared not use too many small players in the team for such a large-scale event as the Olympic Games. Xie Caixia has rich experience in playing both the winger and the midfielder, so China women’s football team finally chose veteran Xie Caixia instead of Song Xiaoli.

　　Three goalkeepers were used in this 22-person roster, namely Zhang Yanru, Han Wenxia and Weng Xiaojie. It is not surprising that Wei Xiaofen, who has been playing as the fourth goalkeeper, went out. Veteran Liu Yali once again lost the chance to compete in the Olympic Games. Since Shang Ruihua took office, Liu Yali has been working hard, and she is also a versatile person valued by Shang Ruihua. However, the coaching staff finally had to give up her because of the continuous back injury. On the forward line, Lou Xiaoxu’s exit was directly caused by Ma Xiaoxu’s good performance in the game after his recent comeback.

　　Although the list of 22 people has been confirmed, the registration rules for women’s football are different from those for men’s football. The women’s football team has the right to change the list of 18 players and 4 players 24 hours before the start of the game. Moreover, the China Women’s Football Team has only announced the list of 22 players, and the final list of 18 players has not yet been finalized.

　　List of 22 women’s football players in China

　　Goalkeepers: Han Wenxia, Zhang Yanru and Weng Xiaojie.

　　Defenders: Jiang Shuai, Li Jie, Weng Xinzhi, Zhou Gaoping, Liu Huana, Yuan Fan and Kun Wang.

　　Midcourt: Gu Yasha, Wang Dandan, Bi Yan, Zhang Na, Zhang Ying, Pu Wei, Lou Jiahui and Xie Caixia.

　　Forward: Han Duan, Ma Xiaoxu, Xu Yuan and Liu Chan.

　　Men’s Basketball Team: Zhang Kai Ding Jinhui left the team.

　　Yesterday was the deadline set by the International Olympic Committee for athletes to register for the Beijing Olympic Games, and the China men’s basketball team also made layoffs. Ding Jinhui from Dongguan New Century Zhang Kai and Zhejiang Wanma became the last players to leave, while Zhang Qingpeng from Panpan, Liaoning Province and Chloe Wang from Bayi became the last two confirmed candidates.

　　As early as the Stankovic Cup, there were rumors that Zhang Kai and Ding Jinhui would leave the team. They left the team first because of their poor performance in the second half of this year’s warm-up match, and the most important reason is that there is no shortage of people inside the China men’s basketball team. After Yao Ming’s return, China men’s basketball team has Yao Ming and Wang Zhizhi in the center position, while Yi Jianlian and Du Feng in the power forward position. These people are indispensable figures in China men’s basketball team.

　　However, the China men’s basketball team is short of perimeter staff. There are already four people in two positions on the perimeter, while there are only six people in three positions on the perimeter: Zhu Fangyu, Wang Shipeng, Liu Wei, Sun Yue, Chen Jianghua and Li Nan. Chloe Wang and Zhang Qingpeng left this time are both perimeter players, which can be regarded as a supplement to the number of perimeter players. After determining the number, China men’s basketball team will compete in the Diamond Cup with a list of 12 players, and the preparations for the Olympic Games have also entered a sprint period.

　　After the team name list was confirmed, the players of China Men’s Basketball Team spontaneously held a team discussion meeting, and the whole team sat together to discuss some topics.

　　The biggest issue is the relationship between the internal and external lines, which is actually how to strengthen the tacit understanding with Yao Ming. "Before Dayao came back, we discussed how to better cooperate with Dayao." Zhu Fangyu said.

　　China men’s basketball team also discussed how to deal with the relationship between the collective and the individual, how to get out of adversity and other topics. The team has the most heated discussion, and it is also the core topic of the discussion-how to treat the grouping situation.

　　"This is the worst grouping result I can imagine." Yao Ming said, "Our opponents in the same group are very strong, but our goal will not change." In Group B, in addition to the Greek men’s basketball team and the German men’s basketball team, there are also the Spanish men’s basketball team, the American men’s basketball team and the African men’s basketball team.

　　China men’s basketball team list of 12 players.

　　Center: Yao Ming, Wang Zhizhi.

　　Power forwards: Yi Jianlian and Du Feng.

　　Forward: Wang Shipeng, Zhu Fangyu, Li Nan and Chloe Wang.

　　Defenders: Chen Jianghua, Wei Liu, Sun Yue and Zhang Qingpeng.

　　Other projects: there is no special "surprise"

　　In addition to football and men’s basketball, some lists of some sports were also unveiled in advance. However, these lists are obviously less suspenseful, belonging to "open guns", and they are also well-known points for the China delegation to compete for gold, so they failed to bring us special "surprises".

　　In track and field events, Liu Xiang and Shi Dongpeng in the men’s 110m hurdles, Huang Xiaoxiao in the women’s 400m hurdles, Zhang Wenxiu in the women’s hammer throw and Zhou Chunxiu in the women’s marathon are all unsurprising candidates.

　　In women’s tennis, China’s "Golden Flowers" are impressively listed. Zheng Jie, Li Na, Peng Shuai and YanZi take part in singles, while Zheng Jie/YanZi and Peng Shuai/Sun Tiantian play doubles.

　　As a "dream team", there is no doubt about the list of China diving team. The women’s 3m springboard guarded by Guo Jingjing and Wu Minxia is the most sure event. The candidates for the women’s 10m platform are wangxin and Chen Ruolin, the men’s 3m springboard are He Chong, Qin Kai and Wang Feng, and the men’s 10m platform is Zhou Lvxin, Lin Yue and Huo Liang.

　　Shooting is also the dominant event of the China delegation. Due to the transparency of selection and qualification, its list was published early. Tan Zongliang, Zhu Qinan, Jia Zhanbo, Du Li, Zhao Yinghui, viki and Chen Ying are all familiar names.

　　As both advantageous events, the competition in gymnastics is fierce. Now only the men’s gymnastics is clear. Due to the strong comeback in the first half of this year, Li Xiaopeng broke into the Olympic team at the last minute. Li Xiaopeng, Yang Wei, Huang Xu, Chen Yibing, Zou Kai and Xiao Qin, the three old teams and three new teams, are indeed the strongest configurations of the China men’s gymnastics team at present. In contrast, the list of women’s gymnastics teams is relatively difficult to produce, because except Cheng Fei, Jiang Yuyuan, Yang Yilin and He Kexin, there are actually seven players competing for the remaining two places.

　　The most interesting thing is that table tennis and badminton are both "still hiding half her face from us behind her guitar", and the entry list has been delayed. The only exception is the women’s singles of badminton. Because of the unstable performance of the "newcomers", Zhang Ning, a gold medalist and veteran of the Athens Olympic Games, finally played with Xie Xingfang.

　　And some slightly unpopular events are still familiar names. In boxing, Zou Shiming plays in the 48kg class, while in Taekwondo, Chen Zhong, who is over 67kg class, strives for three consecutive championships, while in the 49kg class, Wu Jingyu, the upstart, guards it. In equestrian, Huatian has been hyping for too long.

　　A few days ago, the State Council issued the Guiding Opinions on Establishing a Modern Hospital Management System, which will basically form a modern hospital management system by 2020. The "Opinions" put forward three aspects: perfecting the hospital management system, establishing and perfecting the hospital governance system, and strengthening the party building in hospitals, with a total of 20 reform tasks: gradually canceling the administrative level of public hospitals; The heads of health departments at all levels shall not concurrently serve as leaders of public hospitals; Establish a salary system that adapts to the characteristics of the medical industry; It is forbidden to set income-generating indicators for medical staff … …

　　What will happen in the future? What reform dividends will medical staff reap? What will the hospital look like in 2020?

At present, some unscrupulous operators sell fake and shoddy drugs by packaging them as "magic doctors" and "magic medicines", fooling the elderly into buying them and illegally seeking huge profits.In this regard, the China Consumers Association reminds elderly consumers to improve their awareness of risk prevention and self-protection ability.

Drugs without an approval number are counterfeit. Don’t buy drugs through informal channels.

First, we should buy drugs through regular channels such as hospitals and pharmacies, and carefully check the approval number of drugs. Except for Chinese herbal medicines and Chinese herbal pieces that are not subject to examination and approval management, drugs listed in China shall be approved by the drug supervision and administration department of the State Council, and can be listed only after obtaining the drug registration certificate and approval number, so as to ensure the safety, effectiveness and quality controllability of drugs. Consumers should try to choose hospitals, clinics, pharmacies and other formal places (including e-commerce platforms) that hold the Drug Business License and Business License to buy drugs, and carefully check the approval number (national medicine quasi-font number) and expiration date of drugs. Consumers can make inquiries and verification on the website of National Medical Products Administration. Consumers should never buy drugs that have no approval number or can’t find the information of national medicine quasi-brand name on National Medical Products Administration website, so as to avoid being infringed by counterfeit drugs.

In May, 2021, Wenzhou Market Supervision Bureau of Zhejiang Province announced a typical case of "Iron Fist" action in the field of people’s livelihood in the city recently, one of which was "Longwan District Market Supervision Bureau investigated and dealt with Yang Mobin’s suspected case of producing and selling counterfeit drugs". On February 25th, 2021, law enforcement officers of Yongxing Institute of Longwan District Market Supervision Bureau inspected Yang Mobin’s residence according to the report clues, and found 8 bottles of "new gout specific medicine", and the outer packaging was marked with "Function indication: acute and chronic gout, this medicine has the effects of expelling wind and removing dampness, dispelling cold and relieving pain & HELIP; …” Words such as, in line with the definition of drug, but the product has not obtained the drug approval document. The above drugs were tested by Wenzhou Food and Drug Inspection Science Research Institute, and dexamethasone was detected. Yang Mobin’s act of selling the above-mentioned counterfeit drugs is suspected of violating the provisions of Article 141 of the Criminal Law, which constitutes the crime of selling counterfeit drugs. At present, the case has been transferred to Longwan Branch of Wenzhou Public Security Bureau for investigation according to law.

Foods with significant medical effects are likely to be illegally added with drugs.Products are harmful to health.

Food is not medicine, and it has no effect on treating diseases. For some "foods" that claim to be able to treat diseases, they are either false propaganda or drugs are probably illegally added. Long-term consumption of such "food" will bring great health risks to consumers.

Among the typical cases of the fourth batch of 2021 cases in the field of people’s livelihood investigated and dealt with by the General Administration of Market Supervision on August 24th, there was a case in which the Market Supervision Bureau of Jiyuan City, Henan Province investigated and dealt with Huang and others selling illegally added drugs and food. On July 5, 2021, Jiyuan Municipal Market Supervision Bureau received complaints from consumers, saying that the pollen yam tablet candy it bought in Huangmou had a very good hypoglycemic effect after taking it, but at the same time there were a series of adverse reactions. After inspection, glibenclamide was detected in the product. Glibenclamide is a prescription western medicine with obvious hypoglycemic effect. Because of the obvious side effects, long-term large-scale use will cause hypoglycemia and kidney disease, and even lead to death, so the drug can only be used by specific people and needs to be taken under the guidance of a doctor. The behavior of the parties concerned is suspected of violating the provisions of Article 38 of the Food Safety Law "No drugs shall be added to the food produced and operated" and the provisions of Article 144 of the Criminal Law, which constitutes toxic and harmful food in production and sales. At present, the case has been transferred to the public security organs.

"imperial doctor"The "magic medicine" is a false advertisement. Don’t lose your health in pursuit of it.

In order to obtain economic benefits, some unscrupulous operators publish false and illegal advertisements involving traditional Chinese medicine, and induce consumers to buy and use them through false or exaggerated curative effects. This behavior not only affects the healthy and orderly development of Chinese medicine, but also adversely affects the life, health and safety of consumers.

In the fifth batch of typical cases of investigating and handling "Tiequan" in 2021 people’s livelihood cases announced by the General Administration of Market Supervision on September 29, there was a case that "Qilihe District Market Supervision Bureau of Lanzhou City, Gansu Province investigated and dealt with the false advertising case published by Gansu Zhuoyuantang Internet Hospital Co., Ltd. according to law". On March 17, 2021, the Qilihe District Market Supervision Bureau conducted an on-site inspection of Meilin County Chinese Medicine Clinic of Gansu Zhuoyuantang Internet Hospital Co., Ltd. according to the clues reported, and found a large number of "Product Introduction — Ninger Formula, Product Introduction — The advertising materials of the product "Huofei Prescription" are printed with the words "ancient prescription and ancient method for collecting and processing drugs". After investigation, the company published "Lanzhou Zhuoyuantang Chinese Medicine Museum — — The article "Pioneer of online diagnosis and treatment" promotes "the annual number of medical visits is more than 100,000"; The first online consultation Internet hospital in Lanzhou — 　 — The article "Zhuoyuantang Chinese Medicine Hospital" promotes "specially invited Chinese medicine academicians, Chinese medicine masters and outstanding Chinese medicine experts inside and outside the province" and other contents.

The company’s advertising is inconsistent with the facts and seriously misleads the public. The above-mentioned behavior of the parties violates the relevant provisions of Articles 16 and 28 of the Advertising Law and is an illegal act of publishing false advertisements. Qilihe District Market Supervision Bureau imposed an administrative penalty of 800,000 yuan on the parties according to law.

　　China Weather Network News "Others laugh at me for wearing thick clothes, and I laugh at others for being frozen." After a cold wave at the beginning of November, the cold air was uninterrupted, and many places in China experienced a night of winter. Today (November 10th), a new strong cold air has been delivered, with a sharp drop in temperature and a wide range of influence. It will go all the way south to northern South China, and 30 provincial-level cities will hit a new low in the second half of this year. Coincides with the "Double Eleven" period, it may not only be a shopping cart, but also a bone-chilling cold. China Weather Network launched a national early warning map of down jackets to see where it will experience bone-chilling cold, and it is necessary to wrap a long and thick down jacket.

　　National down jacket warning map released, two-thirds of the country needs down jacket protection.

　　At the beginning of November, affected by the cold wave, many places experienced a big reversal of cold and warm, taking off cool summer clothes and turning out warm equipment such as long pants and coats. However, the cooling is far from over, and a new cold air has been delivered. From now until the beginning of next week, a large-scale temperature bottoming contest will be held in the central and eastern regions of China, and 30 provincial-level cities will set a new low in the second half of this year.

　　According to Zhang Juan, a meteorologist of China Weather Network, this strong cold air process will boost the winter process in North China, Huanghuai and other places, and the impact will also go deep into the south, bringing about a big temperature dive, and two-thirds of the country needs down jackets to protect itself.

　　According to the national early warning map of down jackets launched by China Weather Network, three days from now, Northeast China, Inner Mongolia and other places will experience the freezing cold, and the areas that need to wear down jackets will go south with the main body of cold air and reach the northern part of South China.

　　On November 10th, the main body of cold air mainly affects friends in the north, Qinghai, most of Tibet, the northeast and the central and eastern Inner Mongolia. The lowest temperature can be reduced to -20℃ to -15℃, and it will be frozen in minutes when going out, and the temperature is below freezing point during the day. It is necessary to wrap a long thick down jacket in cold weather all day. Most of Xinjiang, North China, Huanghuai, Shaanxi-Gansu-Ningxia and other places will also experience the cold below freezing point in the morning and evening. For example, the lowest temperature in Beijing dropped to -3℃ on the morning of the 11th, which will set a new low in the second half of this year, and it is also necessary to keep warm and wind-resistant down jackets.

　　On November 11th, with the cold air heading south, the highest temperature in most parts of the south of the Yangtze River will drop to around 15℃. Although it is not as chilly as the north, the temperature will also hit a new low in the second half of this year. Coupled with the rain, the wet and cold feeling is obvious, and it is not enough to wear a coat. You can apply for a down vest.

　　On November 12, cold air continued to penetrate south, and the area where down jackets were needed was extended to the south of the Yangtze River. Like Changsha, the highest temperature on the 12th will drop to 9℃, so it’s time to put on a down vest. As the temperature drops in eastern Inner Mongolia, northwestern Shanxi, northwestern Shaanxi and some places in Xinjiang, it will be frozen all day, so it is necessary to wrap a long thick down jacket when going out.

　　After the cold wave crosses Nanling Mountain, its influence will be obviously weakened, and its influence on most parts of South China is a spent force. The cooling range is limited, and the maximum temperature will drop from 30℃ to about 20℃. The body feels slightly cool, long sleeves and coats are enough, and down jackets will continue to press the bottom of the box.

　　How to choose down jackets these three misunderstandings need to be avoided.

　　The footsteps of winter continue to press south, and the weather is getting colder and colder. Down jacket is essential as the ultimate warm artifact. China Weather Network has identified three misunderstandings in the selection of down jackets. Have you been recruited?

　　The quality of down jacket can be identified from the aspects of filler, bulkiness, softness and fabric, which can refer to the four-step method. At first glance, the filler can be identified. Check the label to find out the type and content of the filler. A down jacket with less than 50% cashmere can’t be called. Press twice to test the bulkiness. By pressing down the down jacket to test the bulkiness, the down jacket with high bulkiness has enough air layer to strengthen the warmth. Three touches, experience softness. Feel the softness of the down jacket by touching it. The down jacket with high softness has lower down stalk content and higher down feather content. Four beats, beat the down jacket to test whether the fabric is hairy.

　　The strong cold air process coincides with the "Double Eleven", and many small partners’ goods have already flown on the road, and the rain and snow weather brought by cold air may affect the progress of logistics and distribution. Snowfall will occur in Xinjiang, Qinghai and other places, and logistics may be blocked; There will also be a large-scale precipitation and logistics slowdown in the south. Vehicles are easy to slip in snowfall weather, which increases the hidden danger of traffic accidents and thus affects the timeliness of logistics distribution. Express logistics enterprises need to pay special attention to weather forecast and early warning and other relevant information, make emergency plans for sudden weather changes, strengthen after-sales service links such as logistics distribution and cargo transshipment, and minimize the impact of disastrous weather on logistics and transportation.

　　China Weather Network reminds us that this year’s "Double Eleven" express is under great pressure, and the delivery task of the courier brother is even more arduous due to the cold weather and inconvenient transportation caused by rainy and snowy days. If there is a short delay in delivery, everyone can give more tolerance and understanding. Finally, I wish everyone’s packages can arrive in time without being affected by the weather.

Reference Table of Commonly Used Drugs for Home Treatment of Infected Persons in Covid-19:

3. How to protect family members?

The Guide suggests that when you are at home, you should open doors and windows regularly every day to keep indoor air circulation. If you don’t have natural ventilation conditions, you can use exhaust fans for mechanical ventilation. Do a good job in ventilation and disinfection of shared areas such as toilets and bathrooms. Wash hands or disinfect hands when preparing food, defecating before and after meals, taking off masks, etc. Cover your nose and mouth with a tissue when coughing or sneezing, or cover your nose and mouth with the inside of your elbow, and throw the used tissue into the trash can. Do not share daily necessities with other family members. Tableware should be cleaned and disinfected after use. The surfaces of articles that may be contacted by home therapists and the towels, clothes and quilts they use should be cleaned and disinfected in time, and the personal belongings of infected persons should be placed separately.If the family shares the bathroom, the home treatment staff should disinfect it every time they use it; If family therapists use a separate bathroom, they can be disinfected once a day.

Articles contaminated by saliva, sputum, etc. shall be disinfected at any time.

4. When can I end the home treatment?

The Guide makes it clear that if the symptoms of home-based therapists are obviously improved or have no obvious symptoms, the self-test antigen is negative, and the Ct value of Covid-19 nucleic acid detection for two consecutive times is ≥35 (the interval between the two tests is more than 24 hours), home-based therapy can be ended, and normal life and going out can be resumed.

5. What should I pay attention to when I go to the hospital?

Shen Ning, vice president of Peking University Third Hospital and director of the Center for Infectious Diseases: If you have fever and related respiratory symptoms and need to see a doctor, you should go to the fever clinic. When visiting a doctor, observe the relevant regulations of the hospital, especially self-protection, wear N95 mask regularly throughout the whole process, and comply with the relevant requirements of the hospital for nucleic acid and antigen. If you suspect that you have related upper respiratory symptoms and are worried about the risk of going to the hospital, you can choose online medical treatment, find experts in infectious diseases, respiratory medicine, Chinese medicine and related departments for consultation, and judge whether you need to go offline for medical treatment.

6. The emergency department and fever clinic can prescribe medicine for up to three days, but it hasn’t recovered after three days. Do you need to go to the hospital for reexamination?

Shen Ning: The self-limiting process of upper respiratory tract infection is about 5-7 days. Many patients’ symptoms are not completely relieved after 3 days. If the symptoms are relieved to a certain extent after 3 days of medication, there is no need to rush to return to the clinic. It is recommended to further observe the changes of symptoms. If the symptoms get worse, you must go to the hospital for a follow-up visit.

7. Can Chinese medicine and western medicine be taken together to treat Covid-19 infection? Can a variety of Chinese patent medicines be eaten together?

Liu Qingquan, President of Beijing Hospital of Traditional Chinese Medicine: At present, according to the research and clinical observation, Chinese patent medicines for treating COVID-19 and colds can be combined with western medicines such as antipyretic and analgesic drugs. Just to be on the safe side, Chinese medicine and western medicine should be separated by half an hour. If the ingredients of "Chinese patent medicine" used include drugs with western medicine for relieving fever and pain, attention should be paid to the combination of them, and side effects may occur after the drugs are superimposed. It is recommended not to combine several drugs, including traditional Chinese medicine and western medicine. As a result of combined use, there will be overlapping of drug doses, which has certain risks and will not improve the curative effect.

8. What traditional Chinese medicines can be selected?

Liu Qingquan: At present, all the Chinese patent medicines for treating colds and flu, especially those with wind-heat syndrome and external cold and internal heat (cold containing fire), have a very good effect on treating Omicron mutant.

9. How to protect pregnant women?

Qiao Jie, Dean of Peking University Third Hospital and Academician of China Academy of Engineering: If pregnant women’s family members are infected, they should be relatively isolated in space as far as possible if possible, and their living items should be separated as much as possible, and the bathroom should be disinfected, and the living space should be ventilated as much as possible. If a colleague is positive, try to work at home as much as possible. If you must work in the same space at the same time, pay special attention to the ventilation of the office space and wear N95 mask. Pregnant women should go to public places as little as possible, and do not get together or have dinner. Pay attention to hand hygiene while wearing a mask. Maintain balanced nutrition, adequate sleep and a positive and optimistic attitude. Pay attention to the standardized wearing of N95 mask when you go to the hospital for check-up, and reduce the waiting time. If you have any questions, you can consult in the form of online medical care.

10. What are the symptoms of pregnant women infected with Covid-19? Will it affect the fetus?

Qiao Jie: After the pregnant women were infected with Covid-19, the overall incidence, symptoms and course of disease were similar to those of the general population. The main symptoms were upper respiratory tract infection, such as cough, sore throat, sneezing, stuffy nose, runny nose, general aches and fever, and the severity was very few. The course of disease is basically 5-7 days, and the severe cases are mainly related to basic diseases, such as poor liver and kidney function, hypertension, diabetes, etc., which need to be treated in time. The mother has the protective barrier of placenta, so it is hardly transmitted to the fetus. However, if it is postpartum, it is best for Bao Ma to be isolated from the newborn or wear N95 mask to breastfeed.

11. How do pregnant women respond to symptoms?

Qiao Jie: When pregnant women have respiratory symptoms such as fever and dry cough, they can do nucleic acid test or antigen test to determine whether they are infected with Covid-19. Drink plenty of water, cool down physically, and choose traditional Chinese medicine available to pregnant women for symptomatic treatment. If western medicine is used to reduce fever, acetaminophen can be used for treatment if the temperature exceeds 38.5 degrees. When choosing antipyretic drugs, choose a single drug, and don’t stack it to reduce possible liver and kidney damage. Pay attention to monitoring heart rate, blood pressure and body temperature. Pregnant women in the third trimester should also pay attention to the monitoring of fetal movement, which can be monitored for one hour every day and have more than three fetal movements every hour. If the symptoms persist for more than 3 days, the fever does not improve after taking antipyretics, or fetal movement disappears, chest pain, chest tightness, abdominal pain, etc., you should contact the midwifery institution in time and see a doctor in time.

12. If COVID-19 is positive, can she give birth by herself?

Zhao Yangyu, director of the Department of Obstetrics and Gynecology, Peking University Third Hospital: Whether Covid-19 is infected or not, the choice of delivery mode is determined according to obstetric indications, and the doctor makes a comprehensive evaluation. For example, simple Covid-19 positive, no natural childbirth taboo (such as poor heart function, severe lung function, etc.), as long as you can tolerate the whole process of vaginal delivery, you can still choose natural childbirth.

13. What are the manifestations of children infected with COVID-19?

Qian Suyun, chief physician of Beijing Children’s Hospital: Most children mainly have fever, cough, runny nose and stuffy nose. Some of them are atypical symptoms, including fatigue, poor appetite, vomiting and even diarrhea. There are also some children who will have wheezing and hoarseness. However, the degree of children’s fever varies greatly from individual to individual, and some children can have a higher fever, even more than 39 degrees or 40 degrees. It is observed that most children have a fever in about 2-3 days. So the course of disease is about 3-5 days. The probability of serious illness is very low.

14. What medicines can families with children store?

Qian Suyun: Families with children should properly store some emergency drugs commonly used by children, but it is not recommended to store a lot of drugs. Improper storage may lead to children taking them by mistake. It is recommended to reserve drugs. The first category is antipyretic drugs. For children over 6 months, you can choose ibuprofen or acetaminophen, and one of them can be enough. Children between 2 months and 6 months are not suitable for ibuprofen, but acetaminophen can be used. For children within two months, it is not recommended to use antipyretic drugs routinely, and measures such as physical cooling can be taken and timely medical treatment can be taken. Cough is conducive to the discharge of respiratory secretions. Routine use of drugs is not recommended for children with mild cough. If there is nasal congestion and obvious cough, you can do atomization and wash your nose. At home, you can use a humidifier to increase the humidity in the air. If you have obvious cough, you can prepare some Chinese patent medicines for clearing heat and eliminating phlegm, and choose drugs suitable for your age, but don’t take two or more at the same time. Antipyretic drugs do not advocate taking the two drugs at the same time, and there is no need to take them alternately. Use drugs according to the age, dosage or doctor’s advice recommended in the instructions, and pay attention to the interval between two drugs. It is best for parents not to give drugs to their children according to their own experience or speculation. They can get medical advice and recommendations from professionals through the Internet.

15. Under what circumstances does the child need to be sent to a doctor?

Qian Suyun: The simplest way to distinguish is to look at the child’s mental state. If the child has fever and other symptoms, but he is in good spirits and can eat, drink and play after the fever has gone down, he can continue to observe and treat the symptoms at home. It is recommended to go to the hospital in the following situations: the fever lasts for more than 3 days and there is no sign of improvement; The child’s mental state is not good, including that the baby sometimes cries, is annoyed and is not easy to appease, and the older child is sleepy, listless and looks bad; In addition, cough is getting worse, which affects daily life and sleep; Some children wheeze, breathe faster, even have difficulty breathing, and have obvious hoarseness. Be careful of laryngitis and laryngotracheitis; If you have consciousness disorder or convulsion, you should see a doctor immediately. Children under three months are a special group, including newborns and infants. Once they have fever, it is recommended to see a doctor in time.

16. How should the elderly protect themselves?

Li Yanming, Director of Department of Respiratory and Critical Care Medicine, Peking Hospital: First of all, we should vaccinate, including whole-course vaccine and booster vaccine, which can obviously reduce the incidence of severe illness. Second, reduce going out, especially avoid going to closed places where people gather. If you really need to go out, wear a mask. Try to minimize contact with the external environment during the whole process, and wash your hands when you come back. Third, pay attention to keep warm while strengthening ventilation. You can put your elderly friends in another room and let them return to the room after the ventilation is over and the room temperature returns to normal. Fourth, to control basic diseases, we can buy medicines through various channels, or let relatives and friends buy medicines. Fifth, ensure regular sleep and nutrition, but don’t overeat. Reduce alcohol and tobacco as much as possible. Family members who don’t live with the elderly can reduce their visits and reduce the chances of virus exposure in the near future. If the co-residents are infected with Covid-19, they can live alone if conditions permit. If conditions do not allow, it is necessary to have an independent room, close the door and strengthen ventilation. Patients should be cleaned and disinfected after touching toilets, door handles and faucets.

17. What are the precautions for drug use in the elderly?

Li Yanming: After the elderly are infected with Covid-19, we should first strengthen observation and monitoring. Second, we should strengthen daily care, including light diet. After infection, the gastrointestinal function of the elderly is not good. It is recommended to eat less and eat more meals to avoid vomiting after eating a lot of food at one time. Ensure sleep; Replenish a proper amount of water, combined with body temperature and sweating, a small amount for many times, to prevent gastrointestinal discomfort and increase heart load caused by a large amount of water supplement at one time. Third, the higher the body temperature and the older you are, the more careful you should use drugs to prevent the elderly from sweating a lot after using a fever to cause collapse or even hypotension; In addition, the fever should be slowed down, and the fever can be reduced by physical means; Avoid using multiple drugs together when using antipyretics and cold medicines. Fourth, the application of proprietary Chinese medicines should be less and more precise, and multiple proprietary Chinese medicines with the same function should not be used at the same time. Fifth, the elderly with basic diseases should strengthen the management of basic diseases. A large amount of water loss caused by fever may lead to a decrease in blood pressure. During the fever, especially when antipyretics are used, pay attention to blood pressure monitoring. If the blood pressure is lower than the normal level, the antihypertensive drugs should be reduced or even stopped, and then used as usual when the blood pressure returns to normal. The elderly may eat little after infection, so it is necessary to monitor the changes of blood sugar to prevent hypoglycemia. When the elderly have fever and weakness, they must prevent falling.

18. Under what circumstances do you need to send the elderly to the hospital?

Li Yanming: We should strengthen the observation of the elderly and understand their basic situation. Such as basal heart rate, basal blood pressure, respiratory rate per minute and body temperature. For the elderly with cardiopulmonary diseases, it is necessary to know their basic peripheral oxygen saturation. Observe the changes of the general situation of the elderly, such as conscious state, mental state, defecation and eating. If the following situations occur, you need to consider seeking medical treatment: First, symptoms such as fever persist or tend to worsen. Second, there are new symptoms, such as chest pain, dyspnea, incontinence or sudden immobility of limbs, especially unilateral immobility of limbs, or inability of the elderly to eat, nausea and vomiting, or drowsiness, unconsciousness and disorientation. In addition, the aggravation of basic diseases, such as coronary heart disease in the elderly themselves, leads to angina pectoris; It turned out that there was chronic obstructive pulmonary disease or asthma, and there was an aggravation of chronic obstructive pulmonary disease and asthma, and they all needed to see a doctor.

19. What should cardiovascular patients pay attention to?

Zhou Yujie, Executive Vice President of Beijing anzhen hospital: Patients with original cardiovascular diseases are taking basic drugs. Drinking more water after high fever may affect the symptoms of heart failure, such as drugs for relieving muscle soreness and cardiovascular drugs. At present, no adverse effects between them have been found, so there is no need to be anxious. Manage the basic diseases of the heart well, use the original drugs for cardiovascular diseases well, increase the body’s immunity, improve their sleep quality and overcome anxiety. Don’t stop taking drugs for cardiovascular disease prevention and control for a long time. If you have persistent chest pain, seek medical advice promptly. Pay attention to keep warm, control the intake of sugar, oil and salt, and keep moderate exercise, not too intense. Monitor blood pressure, heart rate and blood lipid regularly.

20. How to sterilize at home?

Lu Lian, Director of the Hospital Sense Management Office of beijing ditan hospital, said: The risk of being infected by household items after "Yangguo" home rehabilitation is very small. The family can do daily cleaning without terminal disinfection. You can unplug the refrigerator and wipe it with a wet towel containing alcohol. Food that is not sealed in the refrigerator is heated before eating. Wipe hard surfaces such as toilets, desktops and cabinets with alcohol wipes or chlorine-containing disinfectant. Cotton items can be washed normally in the washing machine, and the quilt can be dried in the sun. Physical disinfection methods such as sun exposure and heat are preferred at home. To do a good job of ventilation, it is recommended to ventilate 2-3 times a day for at least 30 minutes each time. Household disinfection should focus on cleaning, supplemented by chemical disinfection.

21. What should I pay attention to when disinfecting?

Peking Union Medical College Hospital: Spraying 75% alcohol in a confined space for air disinfection may easily lead to fire or even explosion. Use chlorine-containing disinfectant to disinfect the surface of metal countertops or leather products that are easy to corrode. Disinfectants cannot be used to directly disinfect the human body. Stimulating the airway after inhalation will lead to cough and even destroy epithelial cells. It needs to be wiped after spraying with disinfectant, and pure chemical action can’t completely disinfect it. After disinfection with chlorine-containing disinfectant, the list of objects should be cleaned. The concentration of disinfectant used should not be too high or too low. Different types of disinfectants should not be mixed. Disinfectant can’t be added to the laundry detergent, and a large amount of water is diluted during washing, which can’t play a disinfection role; Chlorine disinfection will corrode and destroy the inner container of washing machine.

22. How long can I return to work after the fever has gone down?

Li Dongzeng, Chief Physician, Department of Infectious Diseases, Beijing You ‘an Hospital: Under normal circumstances, the symptoms of cough, nasal congestion, runny nose and sore throat will be obviously relieved in 3 days after the body temperature is normal. When somatosensory sore throat and cough no longer affect sleep, it means that the body has basically recovered and is suitable for returning to work. After 7 days of onset in young adults, the nucleic acid gradually turned negative, and the infectivity was low. COVID-19 should still do a good job of respiratory protection after recovery, and do not lower the prevention and control standards. After returning to work, stick to wearing masks in crowded and closed public places, pay attention to hand hygiene, cough, sneezing and other etiquette. Don’t eat face to face in the canteen.

23. Is there a high chance of reinfection after rehabilitation?

Zhong Nanshan, academician of China Academy of Engineering: After being infected with Omicron once, antibodies will be produced in the body, which is equivalent to being vaccinated once. At present, the data show that after being infected with Omicron once, the rate of reinfection within one year is very small.

Wan Mobin, Chief Physician, Department of Infectious Diseases, Shanghai Changhai Hospital:There are three types of people who are more susceptible to repeated infections, including the elderly, people with basic diseases and people with poor immunity.Self-protection awareness should be strengthened after the cured confirmed patients in COVID-19 are discharged from hospital and asymptomatic infected people are released from isolation. Vaccination, wearing a mask, keeping a social distance of 1 meter, and trying to avoid being in crowded and poorly ventilated indoor spaces are still effective ways to prevent repeated infections. In addition, in daily life, we should also increase nutrition, especially increase the intake of protein, keep exercising, ensure a good attitude and improve the body’s immunity.The risk of reinfection, as well as the symptoms after infection, depends on many complicated factors, including the variation of variants, vaccination and previous physical conditions. It is true that a small number of infected people are at higher risk after reinfection, but for most people, there is no need to worry too much about the aggravation of symptoms after reinfection.

24. What are the taboos for vaccination?

Beijing Center for Disease Control and Prevention: The medical staff at the inoculation point are responsible for the taboo judgment, and the clinicians at the secondary and above medical institutions are responsible for the disease diagnosis. The diagnosis certificate issued should specify the recent detailed state of the patient, so as to facilitate the taboo judgment at the inoculation point. Taboos include: ① severe allergic reactions, such as anaphylactic shock and laryngeal edema, occurred during previous vaccination; ② Acute infectious diseases are in the fever stage and vaccination is suspended; ③ Vaccination is suspended for serious chronic diseases during acute attack, such as cancer patients undergoing chemotherapy, patients with hypertensive crisis, patients with coronary heart disease who have myocardial infarction, autoimmune nervous system diseases in the advanced stage, and epilepsy patients in the attack stage; ④ Life has entered the terminal stage due to serious chronic diseases.

25. Does it mean that the COVID-19 vaccine has not been vaccinated because of the basic disease and other reasons?

Wang Huaqing, chief expert of immunization program of China CDC: There was a serious allergic reaction after vaccination, so we can’t vaccinate this vaccine in the future. Most other situations belong to the situation of slow seeding. In the early stage, because of the basic diseases, the vaccine could not be vaccinated in the evaluation process, and most of them belonged to slow seeding. They have entered the stable period of the disease or the special treatment condition is over. After re-evaluating the conditions, it is still recommended to vaccinate as soon as possible.

26. Is the adverse reaction rate of COVID-19 vaccine for the elderly high?

Wang Huaqing: According to the current monitoring situation, the overall reported incidence of adverse reactions among the elderly aged 60 and above after being vaccinated with Covid-19 vaccine is slightly lower than that of people under 60, and the incidence of serious adverse reactions is basically similar to that of other people, which is less than one in a million.

27. How long is the interval between strengthening immunization?

Beijing Center for Disease Control and Prevention: Vaccination with COVID-19 vaccine can effectively reduce the risk of severe illness and death after infection. The elderly who have no vaccination contraindications and meet the vaccination conditions should be vaccinated as soon as possible, and the booster immunization should be completed as soon as possible after 3 months of complete vaccination.

28. Who is the target group of the second dose of booster immunization?

According to the "Implementation Plan for the Second Dose of Enhanced Immunization of Covid-19 Vaccine" (hereinafter referred to as "Implementation Plan") issued by the Comprehensive Group of Joint Prevention and Control Mechanism for novel coronavirus Epidemic in the State Council, at this stage, on the basis of the first dose of enhanced immunization, the second dose of enhanced immunization can be carried out among people with high risk of infection, people over 60 years old, people with serious basic diseases and people with low immunity.

29. How long is the interval between the second dose of booster immunization?

According to the real world research and clinical trial data at home and abroad, combined with the actual vaccination in China, the time interval between the second dose of booster immunization and the first dose of booster immunization is more than 6 months.

30. What vaccines can be selected for the second dose of booster immunization?

According to the progress of vaccine research and development, all vaccines approved for conditional marketing or emergency use can be used for the second dose of booster immunization. Priority is given to sequential booster immunization, or the second dose of booster immunization with vaccines containing Omicron strain or with good cross-immunity to Omicron strain. The relevant combinations are as follows:

3 doses of inactivated vaccine +1 dose of Kangxinuo intramuscular recombinant Covid-19 vaccine (adenovirus type 5 vector); 3 doses of inactivated vaccine +1 dose of recombinant Covid-19 vaccine (CHO cells) of Chifeilongkema; 3 doses of inactivated vaccine +1 dose of recombinant Covid-19 vaccine (adenovirus type 5 vector) for Kangxinuo inhalation; 3 doses of inactivated vaccine +1 dose of Zhuhai Livzon recombinant Covid-19 fusion protein (CHO cell) vaccine; 2 doses of Kangxinuo intramuscular adenovirus vector vaccine +1 dose of Kangxinuo inhalation recombinant Covid-19 vaccine (adenovirus vector type 5); 3 doses of inactivated vaccine +1 dose of Chengdu WEEK recombinant Covid-19 vaccine (sf9 cells); 3 doses of inactivated vaccine +1 dose of Beijing Wan Tai nasal spray influenza virus carrier Covid-19 vaccine; 3 doses of inactivated vaccine +1 dose of Zhejiang clover recombinant Covid-19 protein subunit vaccine (CHO cells); 3 doses of inactivated vaccine +1 dose of recombinant Covid-19 bivalent S trimer protein vaccine from Shenzhou cells.

On June 6th, the National Development and Reform Commission, the Ministry of Ecology and Environment, and the Ministry of Commerce once again pushed the development of new energy vehicles-"Implementation Plan for Promoting the Updating and Upgrading of Key Consumer Goods and Smooth Resource Recycling (2019-2020)" was released. The importance of this document can basically be understood as the main theme of the post-new energy vehicle era. That night, we took a look at the dynamics in the circle, which is roughly like this:

From a fundamental point of view, this is a promotion document for digesting production capacity nationwide, which is good for all companies in all industries, large and small. On the other hand, the switching of fuel vehicles in China is the icing on the cake. However, this Dragon Boat Festival, the vast majority of car companies and pile companies have spent a uneasy festival. To sum up, people who have no long-term worries will have near worries.

From the point of view of energy supplement, there are several points worthy of attention in this document: how to go in the future in the process of changing tracks from policy-driven to market-driven in China’s new energy automobile industry.

Judging from the logic of the new energy automobile industry in the full text of the policy, it mainly guides the industry from two aspects: encouraging the upstream and downstream of the new energy automobile industry to continue research and development, promoting cost reduction and efficiency improvement, perfecting the energy supplement system and improving the market application of new energy vehicles. The document specifically mentions that it is necessary to learn from the power exchange mode and application experience in the field of public services, and encourage enterprises to develop new energy vehicle products with the combination of charging and power exchange, flexible battery configuration and long driving range. Therefore, we feel it is necessary to show past lives, the power exchange mode, to everyone.

01 Sadness Xia Jiaxi and His Better Place

In 2007, Shay Xia Jiaxi put forward the power exchange technology, and then founded a power exchange company called Better Place in Israel. After the financing of $850 million was changed in 2013, Xia Jiaxi and his dream of Better Place collapsed. Even though the valuation reached an unprecedented $2.25 billion at that time, the hopeless power exchange model was ruthlessly abandoned by capital.

Xia Jiaxi’s Ambition and the Legacy of Better place

In the early days of its establishment, Xia Jiaxi foresaw that the power battery, a key component that directly affects consumers’ desire to buy, would not improve by leaps and bounds in the short term. The most direct way to solve the mileage anxiety is to form the same energy supply efficiency as fuel supply for fuel vehicles. The energy supplement market bred by the emerging industry of electric vehicles will directly subvert the existing energy structure and consumption mode. Under such a market positioning setting, Xia Jiaxi boldly left SAP.

One year after the establishment of Better place, Israel’s first "power exchange station" was established. First, it signed a cooperation agreement with Renault to provide 100,000 Fluence ZE electric vehicles (but the actual order was less than 1%). Better Place started with 750 drivers in Israel, and the charge for electricity exchange service includes battery rent and electricity exchange fee. Although the hardware cost, battery maintenance cost and education cost of consumers and enterprises were incomprehensible at that time, Xia Jiaxi did not hesitate to continue to burn money in Denmark and the United States, but at that time, car companies still had great doubts about the development of new energy vehicles, and the convenience and use cost of customer-side power exchange mode were not particularly different from those of traditional fuel vehicles. Better Place only launched thousands of vehicles around the world until it was closed.

The end of the road for Better Place seems to be ill-timed now. After all, the overall environment of the new energy automobile industry is far from the same. However, Better Place has left a complete chassis power exchange technology for future generations, and the value generated by the experience in the operation process is immeasurable.

02 Phased tasks of State Grid

863 Program-the Beginning of Power Exchange Technology

In 2006, the domestic electric vehicle industry was still in its infancy. The State Grid responded to the call of the country to start the electric vehicle project, and Zhejiang Power Grid is the top priority to implement the project. At that time, the first project leader of Zhejiang Power Grid participated in the project was Mr. Nie Liang (the first person in the domestic market application field of power exchange mode). In 2010, his team developed and completed the first licensed pure electric vehicle in China, and completed the reserve of basic power exchange technology. In the same year, Nie Liang was responsible for building the Zhejiang project of intelligent charging and replacing power service network. Different from Better Place, a pioneer in power exchange, State Grid developed a set of standard box power exchange technology after understanding the chassis power exchange technology. In Hangzhou, 500 power exchange taxis were piloted with Langyue and Prima models and high box standard boxes, and the business model of "separation of vehicles and electricity and mileage charging" was put forward and verified for the first time in this project.

Power exchange stations and standard boxes piloted by State Grid in Hangzhou

It can be said that the power exchange technology was basically a system at that time, and the pilot effect was quite satisfactory. Later, the Beijing-Shanghai trip organized by State Grid set a fire for the development of power exchange. What’s more interesting is that. In August 2010, State Grid joined the "China Enterprise Electric Vehicle Industry Alliance" and served as the chairman of the charging and service professional committee. At that time, State Grid determined the basic idea of its own intelligent charging and replacing operation mode, that is, mainly replacing electricity, supplemented by plug-in, centralized charging and unified distribution. In other words, the development direction of state grid is to change power stations, not. In line with the above development ideas, State Grid also reserves advanced technologies such as battery balancing, battery automatic replacement equipment and battery cascade utilization. These forward-looking explorations and pre-research have laid a solid theoretical foundation for the budding electric vehicle industry, pointed out the general direction of technical development, and established the development path and ideological system of the whole industry. Today, these technologies have been widely used, especially the chassis replacement mode and standard battery box technology, which have become the mainstream of domestic electric vehicles. However, during 2013 -2014, State Grid did suspend the project of replacing new energy vehicles with electricity due to the change of the main task direction of enterprises. We inquired about the relevant historical information and found that apart from the change of the main tasks of enterprises, the irreconcilable contradiction with car companies is also one of the development factors that hinder their power exchange mode. After all, no car company is willing to become a subsidiary of State Grid. At that time, a director of the National Development and Reform Commission once said: "State Grid should put its position right and cooperate with car companies to develop electric vehicles with a more open attitude."However, State Grid’s insistence on the power exchange mode is not only not conducive to its stable position in the electric vehicle infrastructure market, but also more likely to restrict the development of electric vehicles. In other words, the failure to get through the industrial chain has become the biggest factor for the grounding of the State Grid’s power exchange model. On the other hand, the national policies at that time, such as subsidies and the environment of new energy vehicles, were still relatively weak. Therefore, although the State Grid ran through the business model of power exchange, it was unable to open up the industrial chain to form a business ecology due to institutional factors, and it was inevitable to suspend the power exchange project.

03-The sharing mode has no future.

After the State Grid froze the power exchange mode, Tesla, an American star company, demonstrated its 90-second quick exchange technology in 2013, once again detonating the problem of changing the phone all over the world, but soon Tesla will develop specifically for supercharger 3. From a technical point of view, Tesla still follows the chassis power exchange idea of Better place, but it is further improved in speed. But when "Iron Man" saw the fatal defect of chassis-type power exchange-abnormal batteries can not be shared across car models, and the compatibility of power exchange stations is low, so low compatibility can not improve operational efficiency. It is even more unrealistic to integrate the resources of car companies and form a common standard. In such a complicated power changing environment, Tesla silently quit to change the power stage.

Schematic diagram of Tesla power exchange technology

The rise of 04 module box-splitting power exchange technology

In 2014, Nie Liang left the State Grid after seeing the possibility of opening up the industrial chain of the power exchange system and constructing the power exchange ecology. In the same year, Hangzhou Botan was established, and based on the power exchange of State Grid, the low-box standard box battery was further developed. Compared with the standard box of State Grid in 2010, the low-box standard box battery can be directly placed in the vehicle chassis (the original high-box standard box battery of State Grid needs to be placed under the back seat of the vehicle or in the trunk of the vehicle), and the stability and safety of the vehicle are greatly improved. On the other hand, at that time, the large-scale travel business began to exert its strength, and the market segment paid unprecedented attention to the operation economy of fuel and new energy vehicles. The split-box power exchange mode combined with the large-scale travel business perfectly solved the problems of operating costs and energy replenishment efficiency, and the module split-box power exchange ushered in its historical opportunity.

Standard charging cabinet and standard box batteries for module box-changing.

So, what is the principle of module splitting? First of all, the main dimensions of the TEU are completely the same, but according to the iteration of power battery technology, the energy density can be continuously improved. At present, the single TEU is mainly 15KWH (see the figure below). According to the requirements of vehicle models, different numbers of TEU power batteries are arranged on the vehicle chassis (2/4 for passenger cars and 6 or even 8 for logistics vehicles). Because the box size is the same at the initial stage of design, the power exchange station can exchange power for all vehicles using TEU, no matter which main engine factory they are made, thus completing the development of three limited power exchange modes: compatibility of power exchange equipment and vehicle models, compatibility of charging equipment with TEU, and recycling of circulating batteries.

05 Inventory of Power Exchange in China at the Present Stage

In 2016, the chassis replacement technology that sank for a period of time reappeared in the field of vision. This time, Cai Dongqing created Shanghai Aodong New Energy Automobile Technology Co., Ltd., and made continuous efforts in the power replacement business, and then quickly followed up. Sort out the development path of domestic power exchange technology, which is roughly as follows:

Mainstream power exchange technology: module splitting and chassis power exchange, as shown below:

It is worth noting that at present, the two modes of automatic route for power exchange are slightly different. Six-axis robots are mainly used for power exchange in modules, and RGV is mainly used for chassis change, which is roughly as follows.

Market application: Beiqi Weilai Xinchufeng is used for chassis power exchange, Dongfeng, Zotye, Universiade are used for module power exchange, and the number of vehicles put in and the actual mileage of operation are slightly superior.

How to compare the above two power exchange technologies?

We believe that it is not objective enough to compare the above two power exchange technologies only from the actual promotion layout level (such as infrastructure investment, power exchange capacity, site requirements and construction speed, etc.). The reason for this is the following：

Equipment level: manual, semi-automatic or full-automatic power exchange mode can also be selected for box-by-box power exchange, and the investment intensity can be selected according to the actual situation, while chassis power exchange can only be fully automatic, so it has higher capital requirements and limited investment flexibility in practical promotion. However, according to the fully automatic standard, the cost difference between RGV and six-axis robot equipment is not big.

Site expansion level: the chassis can be quickly laid out in containers for power exchange, and the landing speed is slightly faster, but some cities are not allowed to work in containers (such as Guangzhou). Therefore, in terms of policy compliance, the requirements for the construction of sub-box power exchange and chassis power exchange are basically the same.

On the aspect of power exchange capacity: in the fully automatic state, the average daily power exchange capacity can reach about 250 times with little difference. However, there is a point of concern in this respect. According to the public data, although there are more charging compartments in the power exchange stations with the same power exchange capacity, the number of vehicles that can be exchanged for electricity is only slightly more or equal to that of the chassis (we think that the future evaluation of power exchange capacity can not only rely on the single angle of power exchange speed, because the power exchange capacity depends on the number of charging compartments in the station energy supply, From this point of view, the general modular sub-box power station has 120 cells at the same level, while the chassis power station has 28 cells. However, one car in the modular sub-box power station consumes 4 cells on average, so the power exchange capacity of 120 cells, that is, 30 cars at a time, is not much different from that of the whole pad chassis power station with 28 cells. Therefore, there is little or no difference between the two modes from the above three aspects, so there is no way to compare them only from these three points.

With the issuance of the document "Implementation Plan for Promoting the Updating and Upgrading of Key Consumer Goods and Smooth Resource Recycling (2019-2020)", on the basis of encouraging the development of power exchange mode, requirements are put forward for battery modularization and step utilization of batteries. Therefore, which mode can be compatible with more types of vehicles, better connect the front and rear ends of battery step utilization and better adapt to the future modular development of automobile manufacturing is the more important focus.

From the perspective of vehicle compatibility, the power exchange mode should not be a limited energy supplement scene in the end, but an open source energy supplement mode, because the most basic and basic construction purpose of the power exchange station is to be used as a public infrastructure to facilitate public travel, otherwise why do you enjoy subsidies? At present, Beiqi, Weilai and other car companies are leading the chassis power exchange, because the batteries of their respective car companies are opposite-sex batteries compared with other OEMs, the power exchange sites or batteries cannot be universal. However, Dongfeng, Universiade, Zotye and other enterprises adopt the idea of modular box-splitting power exchange based on standard box batteries, which makes the power exchange station shared among different car models, and the battery can be shared, which greatly improves the utilization ratio of the site and the battery. Therefore, from this perspective, it is obvious that modular box-splitting power exchange is more suitable for the current concept of "sharing economy" and is also an intensive use of social resources.

From the point of view of power battery recycling, the mainstream design ideas in the industry at present are as follows

Direct view of step utilization of power battery

From the point of view of echelon utilization, we must first reduce the transformation cost in the process of each degradation, otherwise it will be difficult to land. From the top-level design point of view, the standard of battery should be unified first, and then the battery with smaller relative weight and volume (because it can’t be directly used in section B and section C if it still stays in the direction of the overall special-shaped battery of most models at this stage). Only under these two preconditions can the whole life cycle development of battery be maximized, and the average use cost of power battery at the user’s end will be lower.

Therefore, from the perspective of battery recycling, it is obvious that the case-by-case power exchange built by the standard box system is more in line with the policy and national conditions. However, from the perspective of automobile enterprises, the whole chassis-type power exchange has less changes to the chassis of the whole vehicle body, and the technical level is relatively easier to realize; However, the modular box-changing technology requires higher requirements for body chassis modification and design cycle. However, it is very interesting that the number of car companies that accept the standard box-splitting power exchange system is far more than that of the chassis-type power exchange model (the total number of cars that are actually put in the box-splitting power exchange system is also more than that of the chassis-type power exchange system). It can be said that many car manufacturers are doing power exchange, and obviously many car companies do not want to play with tickets at this level, but stand higher and look farther.

07 written at the end

On June 5, 2016, China Tower established an energy company with a capital of 5 billion yuan to take the lead in entering the terminal market of power battery ladder utilization, which made it possible for standard box batteries used by modular box-changing electric vehicles and power-changing technology companies to be used in large-scale terminals (compared with special-shaped batteries). The integrity of power battery ladder utilization has been further improved, while the extension of battery ladder utilization industrial chain has further reduced the average use cost of power batteries, which will indirectly reduce the consumption cost of new energy vehicles. From the perspective of industrial chain, does it mean modularity?

We gave time to this problem, but for enterprises that insisted on changing electricity in the early stage, in June 2019, the wind started.
