With the approaching of the listing date of M9, more and more information is exposed. Recently, a person close to the supply chain revealed that the innovative composite current collector of lithium battery is expected to be applied in the M9.

The composite current collector is a sandwich structure of "metal -PET/PP polymer material-metal", which replaces the original pure metal foil. It has the application advantages of high safety, long life, high energy density and low raw material cost, and is expected to replace the traditional current collector and become the mainstream material of lithium battery current collector in the future.

Guangzhou Automobile Ai ‘an released magazine battery 2.0, which is the first battery in China to announce the adoption of composite current collector. The first model is Haoplatinum GT. At the launch conference of the car, Ai ‘an also announced the test report of the bullet shooting fully charged battery pack. The results showed that the bullet penetrated three batteries, which caused the battery pack to be short-circuited and burst in an instant, but the battery pack just smoked and did not catch fire, and the temperature dropped to room temperature after standing for 24 hours.

In addition, Contemporary Amperex Technology Co., Limited Kirin battery has adopted a composite current collector, which is mounted on pure electric MPV Krypton 009.

According to the research report of CITIC Jiantou, the composite current collector is both safe and economical, which is a major innovation in lithium batteries. In 2023, the industrial trend has gradually become clear and accelerated significantly, and equipment manufacturers, new copper foil factories, battery factories and end users have accelerated their layout; At the same time, the technology continues to break through, promoting the composite current collector to mass production, and 2023 is expected to become the first year of mass production.

　　"Trams sell well, all because of the large fuel tank." Many investors are so ridiculous. Extended-range hybrid vehicles have eliminated consumers’ anxiety about the endurance of pure electric vehicles, and the share price of LI-W (02015.HK) has been hitting record highs, becoming the first component of the Hang Seng Science and Technology Index (HSTECH).

　　However, shortly after Ideal announced the delivery data of nearly 35,000 vehicles in August, the major shareholder Wang Xing couldn’t wait to continue to "sell and sell"; The growth rate of LI’s monthly delivery volume has slowed down significantly; In addition, in the context of the sharp rise in raw material prices, it is also facing more fierce competition in the price war of the whole vehicle. However, LI is determined to develop pure electric products that have suffered heavy bicycle losses.

　　Wang Xing reduced his holdings by nearly 2 million shares.

　　According to information disclosed by HKEx, Wang Xing, CEO of Meituan-W (03690.HK) and non-executive director of LI, reduced his holdings of LI for four consecutive days. From September 12th to 15th, Wang Xing reduced his holdings by 1,947,900 shares, with an average price of HK$ 157.84 to HK$ 160.51, and cashed in more than HK$ 300 million.

　　On September 3rd, LI announced that a total of 34,914 new cars were delivered in August 2023, up 2.28% from the previous month. So far, the cumulative delivery volume of LI in 2023 reached 208,200 vehicles, a year-on-year increase of 176.1%; In July, the delivery volume of 34,134 vehicles was only 4.7% higher than that of the previous month. The company expects that the number of vehicles delivered in the third quarter will be 100,000 to 103,000, a year-on-year increase of 277.0% to 288.3%.

　　Lin Jiayi, general manager of Xuanjia Fund, told the First Financial Reporter that the growth of LI’s monthly sales slowed down sharply, and the chip loosening and callback were predictable from the perspective of fundamental performance prospects, the continuous deterioration of industry competition and the poor liquidity of the capital market with high interest rates. In the dominant business, the space of family scene is limited, and its short moat may not be stable. The possible expansion of pure electric business is a highly competitive market.

　　Huang Xili, an analyst in soochow securities, said that the delivery in August was higher than that in the previous month, and the steady supply and delivery of vehicles and the continuous growth of terminal orders formed a positive cycle. By the end of August, LI had delivered a total of 208,200 vehicles, up 176.1% year-on-year, and its annual performance was worth looking forward to. In addition, the channel network layout has been accelerated and improved, and the terminal efficiency has been continuously improved.

　　On August 18th, Hang Seng Index Co., Ltd. announced the results of the index review. LI’s share in the Hang Seng Science and Technology Index will be reduced from 9.74% to 8%, and its share with six leading Internet companies will be 8%.

　　At present, most pure tram companies are still mired in losses, and some new forces sell a car, with an average loss of tens of thousands of yuan. However, LI, which has turned losses into profits, has to make efforts in this field to "further broaden the user base and open up incremental markets."

　　"The company plans to launch the 5C pure electric super flagship model in the fourth quarter of 2023, the ideal MEGA. The company is confident that the car will become an explosive model of more than RMB500,000. " LI said in the semi-annual report.

　　"In the new stage of parallel operation of extended-range electric and high-voltage pure electricity, we will continue to improve our research and development capabilities in the fields of intelligence and electrification, optimize our products and expand our product matrix. By 2025, our product matrix is expected to include a super flagship model, five extended-range electric vehicles and five high-voltage pure electric vehicles. " The company also said: "We currently have a manufacturing base in Changzhou, China to produce extended-range vehicles, and are building a manufacturing base in Beijing to actively expand production capacity and prepare for the release of pure electric vehicles."

　　Lin Jiayi believes that in recent days, major car companies are also constantly cutting prices, trying to maintain market share. Under this background, LI’s growth space is facing challenges.

　　Huang Xili said that MEGA is expected to be officially released in December this year, exhibited in stores in January 2024, and delivered by users in February. The launch of MEGA will help LI achieve the goal of being the first luxury car brand in China in 2024.

　　Cui Yan, an analyst at Huaxi Securities, believes that LI’s products should be judged not only by price or body form, but also by what kind of demand the products meet, which stems from the ideal understanding of users’ needs and the extensive demand for family cars. The company has great hope to replicate the success of the extended range series in the pure electric product line to gain greater market share.

　　Car companies whose downstream terminal prices are decreasing are also facing the situation that the upstream raw material prices are rising sharply, which will challenge the gross profit margin: within more than three months since the end of May, major industrial products such as copper and aluminum have risen sharply in three months, and the prices of raw materials have risen in an all-round way. In September, Shanghai Aluminum once approached the 20,000 yuan/ton mark, which caused certain cost pressure on auto parts and vehicle enterprises, especially for electric vehicles, and the demand for aluminum was increasing.

　　China news agency, Beijing, September 6 (Chen Ying) As the world’s largest computer manufacturing base, China’s computer industry has now ranked first in the world.

　　According to the data released by the "2019 World Computer Conference" held in July this year, in 2018, China’s computer industry achieved a main business income of 1.95 trillion yuan, an increase of 8.7% year-on-year; The output of microcomputers is 310 million, and the annual output of servers reaches 2.952 million.

　　It is hard for people today to imagine that China’s first electronic computer — — 103 computers, covering an area of 40 square meters, with an operation speed of only 30 times per second.

　　In January 1953, Hua Luogeng was ordered to set up the first computer research group in China in the newly established Institute of Mathematics of China Academy of Sciences, with Professor Min Dake of Tsinghua University Electrical Engineering Department as the team leader. The goal of this group was to develop China’s own computer.

　　In April 1956, when Premier Zhou Enlai personally led the formulation of a 12-year long-term outline of scientific and technological development, Hua Luogeng was appointed as the head of the computing technology planning group, responsible for drafting the blueprint for the development of computer industry in China. As a result of the implementation of the plan, the Institute of Computing Technology of Chinese Academy of Sciences was born.

　　In 1956, the Preparatory Committee of Institute of Computing Technology of Chinese Academy of Sciences was established in China, and the design of the first small computer 103 in China was completed. It took 8 months for the State-owned 738 Factory to manufacture this computer.

　　In the field of computers, everything is "big" at the beginning. The first computer in New China covers an area of 40 square meters with only a few large cabinets in the mainframe, and there are nearly 4,000 semiconductor germanium diodes and 800 electron tubes in the body.

　　On August 1st, 1958, Computer 103 completed the operation of four instructions, which marked the official birth of the first universal digital electronic computer made by China people.

　　The 103 computer adopts magnetic core and drum memory, the memory is only 1KB, and the operation speed is 30 times per second. Only one year later, the 104 computer came out successfully, and the computing speed increased to 10 thousand times per second. From 30 times to 10 thousand times, it only took more than a year.

　　Since the founding of New China 70 years ago, China’s computer R&D and manufacturing have not only developed from scratch, but also reached the forefront of the world.

　　Supercomputer is a kind of computer with the strongest function, the fastest operation speed and the largest storage capacity. It is mostly used in national high-tech fields and cutting-edge technology research, and is one of the important indicators to measure the level of national scientific and technological development and comprehensive national strength.

　　The first billionth supercomputer in China was "Yinhe -I" developed by the Computer Research Institute of National University of Defense Technology. Its operation speed is more than 100 million times per second.

Peng Wenjun: We are concerned that since 2012, universities directly under the Ministry of Education have arranged 64 universities to be included in the designated poverty alleviation work system. Colleges and universities in our country have played a vital role in the process of getting rid of poverty, especially in the decisive year, and are indispensable forces in the process of getting rid of poverty in the whole country. In a word, the cooperation between universities and local governments in our country is mainly reflected in the combination of blood transfusion and hematopoiesis, and the combination of wisdom and ambition. In particular, the school’s resources are seamlessly connected with local needs, and the school’s scientific and educational advantages are accurately connected with local resources and development foundations. In the process of participating in poverty alleviation, each university is actively exploring and building a new mode of cooperation between schools and places in combination with its own characteristics and the characteristics of poverty alleviation points. There are mainly the following aspects:

1. Poverty alleviation through education lays the foundation for local poverty alleviation. Colleges and universities make use of the advantages of talents to increase the motivation of local development. For example, teaching, pairing, donation, the construction of smart campus, joint teaching, targeted training, and accurate selection and delivery, many measures can lay the foundation for education in poor areas.

2、科技扶贫促进贫困地区产业发展。高校的学科优势转化为地方发展的引擎，主要体现在统筹学科力量，帮助开展技术攻关。比如湖南大学医学特别有特色，对口扶贫的江华县是瑶族区域中南大学把江华县的瑶医、瑶药充分进行技术攻关，进行帮扶。湖南大学利用生物科学的优势，在定点扶贫的龙葵县攻克羊肚菌的种植技术。这些学科优势为地方脱贫起到了很好的引擎作用。

3、文化扶贫。高校的专业优势能够助推解决区域贫困。像湖南的十八洞村，习近平总书记在视察十八洞村的时候首先提出了精准扶贫，也就是说这个村是精准扶贫的首创地。最后湖南省委托湖南大学建筑规划学科的力量，为十八洞村进行援建和设计。整个村的硬件设计、文化设计全部进行包装，形成了十八洞村脱贫攻坚的模式。这也是一种文化扶持的力量。

4、消费扶贫。高校的资源优势可以为对口的扶贫地提供推手和平台，包括农副产品的生产、加工、销售，可以起到很多助力作用。

总的来讲，校地结合、校地融合对于脱贫攻坚发挥了重大的支撑作用。

After crouching

The high temperature in various places continues to spread.

Some people don’t pay attention to it after heatstroke.

Wait until after severe heatstroke

The tragedy is irreversible …

In the past week, the emergency department of Sandun Hospital of Zhejiang Hospital has received many cases of heatstroke every day. A 30-year-old female patient with heatstroke (severe heatstroke) did not turn on the air conditioner at home, and the electric fan was given to the child. By the time the family found out that she was not in the right condition, the patient had fallen into a deep coma.

What took you so long? Her husband explained that "she is not afraid of heat at ordinary times". In the end, the doctors tried their best, but there was nothing they could do.

The doctor stressed that heatstroke is severe heatstroke, and the mortality rate is very high if the rescue is not timely. However, heatstroke usually does not happen suddenly. If there is threatened heatstroke or mild heatstroke, we must intervene in time, otherwise the symptoms will continue to worsen, such as heatstroke and even death.

On the social platform, related topics also rushed to the hot search.

Netizens said

"Poor inherit the wind"

Some netizens don’t understand her husband’s words.

Xiao Bian reminds that in high temperature weather, whether in production or life, we should guard against the personal safety risks caused by summer heat.

Eight Mistakes of Heat Shock Disease

Misunderstanding 1

Heat stroke is heatstroke, so it is not life-threatening.

Heat stroke is the most serious type of severe heatstroke. Heat stroke is not as simple as raising body temperature, but produces a series of terrible physiological reactions. Patients will have multiple organ failure, central nervous system dysfunction, disseminated intravascular coagulation and so on. If it is not properly treated in time, the death rate of heat stroke is very high, and the general death rate can reach 50%-70%, and the death rate of elderly patients over 70 years old will reach 80%.

Myth 2

If you have symptoms of heatstroke, you can cool down at home.

Heatstroke is extremely dangerous once it develops to the stage of heatstroke. When the patient has symptoms of heatstroke such as high fever, no sweat, blurred consciousness, convulsion, or even no response, don’t hesitate to call 120 in time and send him to the hospital as soon as possible.

Misunderstanding 3

Indoor, there will be no heat stroke.

Heat stroke is not exclusive to outdoor, and indoor small environment with high temperature and poor ventilation may also cause heat stroke. Decoration workers and workshop workers who stay in a closed space for a long time belong to the high-risk group of heat stroke; Some elderly people live in old houses with poor ventilation and no air conditioning, and are also prone to heat stroke.

Misunderstanding 4

If you don’t do strenuous exercise, you won’t get heatstroke.

Heat stroke can be divided into labor type and non-labor type, the former refers to strenuous exercise in summer and high-intensity physical activity; The latter is common in the elderly, infants, pregnant women and other people with slightly weaker physique. In the summer of 2022, there was an incident in Shandong where a woman suffered from fever during the confinement period and eventually died of heatstroke.

Myth 5

If the temperature is not high, it is not heatstroke.

Elevated body temperature is the main feature of heatstroke, and the core body temperature of patients is mostly above 40℃. The core temperature mentioned here is often reflected by rectal temperature. Our daily measurement of axillary temperature or ear temperature can only be used as a reference, and can not be used as a basis for the diagnosis of heatstroke.

Myth 6

Only in summer will there be heatstroke.

Heat stroke is not exclusive to summer. For example, workers who work in unventilated high-temperature factories for a long time, firefighters who face raging fires, and even people who steam saunas in winter may suffer from heat stroke.

Misunderstanding 7

In hot weather, eating more cold drinks can prevent heatstroke.

The most important thing to prevent heatstroke is to drink plenty of water, including white water, salt water and drinks containing electrolytes such as potassium, sodium and chlorine. Eating a lot of cold drinks will increase the burden on the stomach. Alcoholic drinks and high-sugar drinks will make the body lose water and are not recommended.

Misunderstanding 8

Women with weak constitution are more likely to get heatstroke.

Generally speaking, women’s heat adaptability is weaker than men’s, but a large number of clinical data show that there are more men suffering from heat stroke than women, which should be related to men’s more outdoor work and heavy physical activities. Such as outdoor high-temperature workers, steel workers, firefighters, athletes, soldiers participating in training, etc. are all high-risk groups of heat stroke.

Diffusion reminds people around you

The heat is scorching

Be sure to watch out for heatstroke!

　　In the past few years, various problems based on AI (artificial intelligence) have been one of the hottest topics in the field of science and technology. How to make this cutting-edge scientific and technological force simpler and acceptable to the people has become a real problem at present. In response to this problem, Baidu gave its own plan.

　　A few days ago, after reaching a strategic cooperation with China Science and Technology Museum, Baidu’s "Voyager" AI Popular Science Bus has started from Beijing, and has been launched in local science and technology museums in five cities across the country. On August 4, 2017, Baidu and science and technology hall held the launching ceremony of "Artificial Intelligence Popular Science China Tour" in Beijing, which marked the first stage of the strategic framework cooperation agreement reached between them based on artificial intelligence popular science. This trip of artificial intelligence science popularization in China has been carried out in local science and technology museums in five cities in China. The "Voyager" AI science popularization bus will spread the knowledge of artificial intelligence to all parts of the country, which also shows that Baidu’s artificial intelligence technology not only changes industries, but also cares about people’s lives. Bring updated artificial intelligence knowledge to further places. Prior to this, Baidu also successfully realized the "restoration" of the damaged Terracotta Warriors and Horses and the intelligent display of related cultural relics through artificial intelligence technology. In addition, Baidu is also committed to using the new AR (Augmented Reality) technology to restore and reproduce the folk life of old Beijing, and use technology to awaken history, so that experiencers can fully experience history and culture and become a part of history.

　　Make the complex world simpler.

　　In fact, it is Baidu’s mission to make the complex world simpler with technology. In the past few years, Baidu has been committed to technological innovation and the development of artificial intelligence. The reason why Baidu can achieve today’s achievements is closely related to the country’s concern and support for the field of scientific and technological innovation.

　　In order to realize the mission of "making the complex world simpler with technology", Baidu will adhere to two core strategies: consolidating the mobile foundation and winning the AI ? ? era. In short, AI is the core driving force of Baidu.

　　It is reported that Baidu AI platform is the foundation of developing application layer, which is composed of Baidu Brain and Baidu AI Cloud. Baidu brain is the first complete artificial intelligence platform in the industry, including algorithm layer, perception layer, cognition layer and platform layer.

At the same time, in order to explore long-term market opportunities, Baidu will continue to expand emerging AI-driven businesses through open platforms and ecosystems.

　　Awakening history and culture with science and technology

　　Awakening history and culture with technology is one of the important practices undertaken by Baidu, the global artificial intelligence giant, in the field of AI, and it is also one of the most intuitive channels for the public to experience the power of AI at present.

　　On August 4th, 2017, Baidu and science and technology hall held the launching ceremony of "Artificial Intelligence Science Popularization in China" in Beijing, which marked the first stage of the strategic framework cooperation agreement reached between them based on artificial intelligence science popularization. This trip of artificial intelligence science popularization in China has been carried out in local science and technology museums in five cities in China. The "Voyager" AI science popularization bus will spread the knowledge of artificial intelligence to all parts of the country, which also shows that Baidu’s artificial intelligence technology not only changes industries, but also cares about people’s lives.

　　On May 18th this year, Baidu announced that it had realized the "restoration" of the damaged Terracotta Warriors and Horses and the intelligent display of related cultural relics through artificial intelligence technology. According to reports, the "restoration" plan uses AR technology to "restore" the Terracotta Warriors and Horses No.2 pit, kneeling figurines and bronze chariots and horses. Visitors can see the "alive" Terracotta Warriors and other cultural relics with their own eyes by scanning the three triggers of "plane layout", "light box of kneeling figurines" and "structure diagram of bronze chariots and horses" in the No.2 pit of Terracotta Warriors and Horses through Baidu AR function of mobile phone.

　　At the same time, the Digital Museum of Terracotta Warriors and Horses built by Baidu Encyclopedia was officially launched, presenting the Terracotta Warriors and Horses to the audience for the first time with the "ultra-high-definition level" of 20 billion pixels, becoming the first historical landscape in eight wonders of the world to be exhibited online with 10 billion pixels.

　　At the beginning of this year, following the restoration of Chaoyangmen by Baidu AR technology, Baidu began to comprehensively upgrade AR technology and completely restore the nine gates of old Beijing as cultural cities. It is reported that Baidu’s activity of restoring the nine gates of old Beijing through AR technology was held during the Spring Festival, so it has attracted the attention of many citizens and friends. During the event, passengers can see all kinds of life scenes of the old people in the old Beijing city after triggering AR through the mobile phone Baidu App, and at the same time, they can also interact with the restored "Old Nine Gates", which is very exciting.

　　Compared with some applications with a strong commercial atmosphere, Baidu’s attempt to awaken history and culture with technology and let the experiencers fully experience history and traditional culture with new AR technology can really make more and more people pay attention to and even participate in the inheritance and protection of history and culture. This also shows that Baidu’s artificial intelligence technology is not only about changing industries, but also about people’s lives themselves. Text/Liu Yang

　　"Stand up straight and stride." Under the guidance of medical staff, Xiao Chen, a running friend, is conducting exercise treadmill experiments in Beijing Hejia Hospital. In the Beijing Half Marathon in April this year, Xiao Chen had a cardiac arrest. Fortunately, he was discovered by the volunteers of Hejia AED, and was successfully rescued through cardiopulmonary resuscitation and AED (External Automatic Defibrillation Transporter) electric defibrillation. After months of recovery, doctors need to re-evaluate his heart function.

　　The start of the 2019 Beijing Marathon is just around the corner, and even senior runners may "stumble" and face the great risk of sudden cardiac death.

　　Cardiology experts remind that six types of patients, such as those who have a history of myocardial infarction, those who have been diagnosed with heart diseases and have undergone surgery, and those who have a history of unexplained syncope, are generally not suitable for marathon. If you want your heart to be safe in high-intensity events, you need scientific cognition and pre-competition heart evaluation.

　　Senior runner’s cardiac arrest AED successfully rescued

　　"I was more excited when I finally sprinted. I shouted and rushed over. After a few steps, my feet were soft and I suddenly lost consciousness." Xiao Chen, a runner who suffered an accident in this year’s semi-Marseille in Beijing, said that he has ten years of long-distance running experience and participated in eight or nine marathons, which is a senior runner. I didn’t expect that this time he became the object of "first aid".

　　At that time, it was Yuan Tong, an emergency nurse in Beijing Hejia Hospital, one of the medical security units of Beijing Half Horse Race, who was present to defibrillate Chen Jinxing AED. She said that the timely discovery of the support staff and the skilled use of AED pulled Xiao Chen back from the death line, otherwise once the cardiac arrest was not treated for 4 to 6 minutes, the brain would be irreversibly damaged, and even if the heartbeat was restored, it might become a vegetative state.

　　Wang Dezhao, chief physician of the Department of Cardiology, Beijing Hejia Hospital, said that cardiovascular system accidents that often lead to cardiac arrest and sudden death in marathons are usually sudden acute myocardial infarction or malignant arrhythmia. Although the probability of occurrence is low, once it appears, it is the most dangerous. It is the most effective way to rescue patients with cardiac arrest and sudden death by using artificial chest compressions and AED defibrillation in the early stage. Beijing United Family Hospital is the official and exclusive designated medical service provider for Beijing Marathon. All AED volunteers have passed the cardiopulmonary resuscitation training organized by the American Heart Association (AHA) and obtained the certificates of Basic Life Support (BLS) and Advanced Life Support (ACLS), so they have the ability to find and rescue runners with cardiac arrest in the first time.

　　Six groups of people should have a heart evaluation before the game.

　　How to run a horse safely? Wang Dezhao said that runners must first have a clear understanding of their physical condition, and the following groups of people are not suitable for participating in such high-risk events.

　　First, patients who had a history of myocardial infarction in the past, especially 6 months after myocardial infarction; Followed by patients who have been diagnosed with angina pectoris, or have undergone coronary stenting, coronary artery bypass grafting and installed pacemakers; Third, it is a patient who has a history of unexplained syncope or has done electrical cardioversion; The fourth is patients with severe arrhythmia or taking antiarrhythmic drugs; In addition, patients with a history of congenital heart disease, cardiomyopathy or cardiovascular malformation, and patients with special ECG manifestations, such as Brugada syndrome, long QT syndrome and preexcitation syndrome (all three groups have special ECG manifestations), are not suitable for high-risk events similar to marathon.

　　In addition to people who are not suitable for horse racing, there are six groups of people who can participate in the marathon, but they need to be evaluated before the race. The first category is people with risk factors of coronary heart disease, including smoking, hypertension, diabetes, hyperlipidemia, family history of premature coronary heart disease (male < 55 years old, female < 65 years old), heavy drinking, sedentary, obesity, staying up late and working under great pressure; The second category is people with family history of sudden cardiac death; The third category is people who have had severe diarrhea or used diuretics recently, and it is very likely that there are abnormal levels of potassium, magnesium and calcium ions; The fourth category is people who have arrhythmia without drug treatment, including sinus arrhythmia, various premature beats, sinus bradycardia, etc. The fifth category is people who have had discomfort in the area below the jaw and above the umbilicus related to activities, or have palpitations and shortness of breath; The sixth category is people who are anxious, hypochondriac and have had a history of panic attacks. Most of these people do not have the typical symptoms of organic heart disease, but they belong to high-risk groups. If there is no heart assessment, there may be unexpected situations in extreme sports such as marathon.

　　Three types of heart assessment help runners stay away from accidents

　　Wang Dezhao introduced that marathon is an extreme sport with certain potential risks. However, as long as the heart function is scientifically evaluated before the game and the physical condition is known in advance, accidents such as cardiac arrest can be avoided to the maximum extent.

　　"If the heart is compared to a house, then it has three systems, including waterway system, circuit system and structural system." According to Wang Dezhao, heart evaluation is also divided into three categories according to three systems: the first category is the evaluation of the "waterway system" of the heart, and the "waterway system" refers to the blood vessels of the heart itself &mdash; &mdash; Coronary artery. If the runner has chest tightness, shortness of breath, chest pain, pressure, burning pain, pain in the left upper limb or left shoulder and back, which suggests that angina pectoris is possible, it should be evaluated by exercise treadmill test to observe whether the runner will have myocardial ischemia when he reaches the limit heart rate, which is also a simple and effective means to screen coronary heart disease. If the exercise treadmill test is abnormal, further coronary CTA or coronary angiography is needed.

　　The second kind of evaluation depends on the "circuit system" of the heart, that is, the evaluation of cardiac electrical activity. If the runner has palpitation, irregular heartbeat, too slow or too fast heartbeat, it suggests that the cardiac electrical activity is abnormal, and it is necessary to do ECG monitoring for 24 hours, 7 days, 1 month or even longer. By monitoring the ECG changes at the onset of symptoms, the disease can be diagnosed and whether it is suitable for the competition can be evaluated.

　　The third category is the evaluation of heart structure. If the runner has heart murmur, myocarditis, cardiomyopathy, congenital heart disease, etc., it is necessary to evaluate the morphological structure of the heart by heart color Doppler ultrasound. If you have serious structural heart disease, especially hypertrophic obstructive cardiomyopathy or aortic stenosis, you are not suitable for marathon.

　　How to predict and save yourself when you suddenly feel unwell in the game? Wang Dezhao said that first of all, runners should stop exercising, rest in a comfortable and relaxed posture, and seek help from medical staff; If the heartbeat suddenly accelerates, fast and even, it may be supraventricular tachycardia. You can hold your breath and cough hard, which may stop the tachycardia. If the pain in the chest or other suspicious parts (back, upper limbs, pharynx, etc.) persists, the attack of acute myocardial infarction cannot be ruled out. It is best to lie on your back, relax as much as possible, take a deep breath slowly and wait for rescue. (Reporter Chen Si)
