Due to the improvement of watermelon varieties and planting techniques, this year’s local watermelons are listed ahead of previous years. In order to facilitate local melon farmers to sell melons in the city, standardize the behavior of selling melons, and fully meet the needs of citizens’ lives, the Urban Management and Law Enforcement Bureau of our city set up real estate watermelon sales points 20 days earlier than last year, and at the same time ensure the sanitation and order of the city appearance and environment. The city adopted the "three-fixed" method of fixed location, fixed area and fixed responsibility, effectively standardized the sales of real estate watermelons in urban areas, and rationally planned fixed locations. On the basis of fully considering the dual needs of urban management and citizens’ life, 149 temporary watermelon sales points were selected and set up in the urban area this year. From June 1 to August 30, a "watermelon map" was drawn, covering the main areas of the built-up areas such as Langya District, Nanqiao District, Economic Development Zone and Suzhou-Chuzhou High-tech Zone, and the general public, melon farmers and mobile phone new media were informed in time.

The listing of Netease Cloud Music caused an uproar in the market, and many people denied this "loss-making business" almost at the first time.

Some people think that it has lost 7 billion in the past three years and still holds a valuation of nearly 50 billion, which is not worth it at all.

Some people think that a company with a negative gross profit margin dares to go public?

Others think that this is another sentimental listing, which is really too weak!

These voices are all reasonable, but they are not quite right when they are placed on Netease Cloud Music.

　Do you think a grid of electricity is weak?

Judging from the "birthday" of Netease Cloud Music, it is definitely a "sweeping monk".

In April 2013, Netease Cloud Music was launched, and people said that Netease Cloud Music was "willing to be cannon fodder".

Because the predecessor of Baidu Music Qianqian Jingting was established in 2003; Cool dog music was founded in 2004; QQ Music was founded in 2005; Kuwo Music and Xiami Music were established in 2006; Tiantianyingmei was founded in 2008 …

When Netease Cloud Music entered the market, cool dogs and QQ music were already big names, and shrimp was not weak. But in this crack, Netease Cloud Music still made 100 million users in two years; Made 200 million users in 3 years; Three years after its launch, Netease Cloud Music also killed Xiami Music, Everyday Music, Douban Music (FM), Domi Music, Baidu Music and Kuwo Music, ranking third in the music category, with only QQ Music and Cool Dog ahead.

Why? Because Netease has seized the dividend of the mobile Internet era-socialization. During the cold start, Netease Cloud Music started a function of importing songs and downloading them for free, which attracted a large number of users of Douban FM and Shrimp at a very low cost.

From the beginning, Netease Cloud Music didn’t intend to be just a "quiet" music player. Instead, we let go of the right to comment on every song, album, song list and mv, giving users a lot of room to play, listening to songs and writing comments, a simple community function, which has captured users.

If we want to evaluate the development of Netease Cloud Music, its success in music APP is just like Pinduoduo’s surprise attack on Taobao.

Although I caught a late episode, I gained a lot. However, late episodes certainly have shortcomings. From the beginning, Netease Cloud Music did not seem to pay too much attention to the importance of "copyright" for itself.

But at that time, the music copyright market was already divided into three parts:

Source: Online public information.

Moreover, compared with Netease Cloud Music, other online players and copyright distribution; There are artist brokers, performance activities and integrated marketing offline, all of which are not just music.

Tencent Music is even richer in the acquisition of copyright. Before Netease Cloud Music reacted, Tencent bought almost all the music copyrights in the world. For example, Tencent is the exclusive agent of Warner, Universal and Sony. There are also the agency rights of companies such as Emperor, Fumao and Jewell.

When Tencent Music was interviewed by the media, it was evenTo say: "We don’t want to monopolize, but they can’t afford it", we can see how strong Tencent’s dominance is.

However, I never expected that Baidu Music had disappeared a few years later, and Ali had closed the shrimp bet.Netease cloud. There are only two forces in the music market, one is Tencent Music, and the other is Netease Cloud.

Although the disparity in strength is relatively large, Netease Cloud actually filled the audience with a grid of electricity like Duanfei in the biography of Zhen Huan.

What’s more, due to the plundering of users’ time by short videos, Tencent Music had 615 million monthly users in the first quarter of 2021, down 6.4% year-on-year. Since last year, the monthly activities of Tencent Music have been declining.

Source: Tencent Music Financial Report

In contrast, from 2018 to 2020, the monthly users of online music services of Netease Cloud Music were 105 million, 147 million and 181 million respectively, which also showed a continuous growth trend, and the compound annual growth rate was 31%; In addition, the number of online music paying users is also rising, reaching 4.2 million, 8.63 million and 16 million respectively, with a compound annual growth rate of 95%.

So if you want to say that Netease Cloud Music is not competitive, then someone will definitely not agree.

　Why did Ali and Baidu bet on a company with negative gross profit margin?

The online music market in China is almost the one with the highest "monopoly" of Tencent except WeChat in the social field. Since Tencent "wooed Cool Dog" and "Cool Me", no one can shake the position of the market leader. This is not to blame Tencent Music. It acted too early and did not give others a chance to surpass it.

There are still fast hand vibrato in the short video field; There are Taobao, JD.COM and Pinduoduo in the field of e-commerce; Iqiyi and Tencent video in the field of long video (film and television drama).

Netease cloud music is preserved like a "kindling", and its strategic shareholders includeAlibabaAnd Baidu, Ding Lei personally served as executive director and CEO. In addition, when the shrimp was shut down at the beginning of this year, Netease Cloud also inherited a large amount of "legacy" of shrimp.

It can be seen that on the music track, the big brothers attach importance to Netease Cloud.

Of course, the bosses can see that Netease Cloud Music does not make money. Supporting it is definitely not just about feelings, mainly because Netease Cloud Music and Tencent Music are still very different in essence.

From the perspective of revenue composition, Netease Cloud Music once paid more attention to online music services. In 2018, the revenue of this sector reached 1.026 billion, accounting for 89.4% of the total revenue. Social entertainment services and other businesses only contributed 122 million yuan in revenue, accounting for a very small proportion of the total revenue. This shows that Netease Cloud Music was still a "teenager with a musical dream" three years ago.

Source: Netease Cloud Music Prospectus

The social entertainment and other income of Tencent Music has always accounted for about 70-80% of the revenue, and the contribution of online music services is only 20-30%. Focus: Tencent Music has made a profit.

In order to increase income, Netease Cloud has also begun to increase the income of social entertainment services and other businesses, and speaking people’s words is to rely on rewards.

Rewarding is always the most effective way to generate income on the Internet. By 2019, the income of Netease Cloud Music Social Entertainment Service and other parts soared by 343.44%, reaching 541 million yuan; In 2020, social entertainment services will once again increase this part of revenue to 2.273 billion yuan with a growth rate of 320.15%, and the proportion of revenue will increase to 46.4%.

At this point, the revenue structure of Netease Cloud Music is gradually balanced in the eyes of capital.

In addition, in 2020, the monthly ARPPU (income per paying user) of Netease Cloud Music in the social entertainment field reached 573.8 yuan, which can be described as "high and scary", but in the same period, the amount of its online music service was only 8.4 yuan, with a gap of nearly 70 times (it seems that making music really doesn’t make money), and the monthly ARPPU of Tencent Music.It is 141.1 yuan.

In other words, the value of a paying user watching live broadcast on Netease Cloud Music is equal to the value of four paying users of Tencent Music, which is the reason why the big brothers are optimistic about the momentum of Netease Cloud Music.

The brilliance of Netease Cloud Music is once again reflected. Who said that the community is useless? Its community stickiness is easy to have a heavy effect in rewarding, while Tencent music must be accumulated through time.

Since its establishment, Netease Cloud Music has received three rounds of financing:

　Source: Online public information.

Among them, in April 2017, it happened to be the day when Netease Cloud Music broke through 300 million users, and accessed Mango and SMG to obtain some pan-entertainment copyrights; In October 2018, it happened to be the moment when Baidu was in all in AI and allowed small speakers to grab the market independently. After joining Baidu, Netease Cloud could get the coveted Taihe copyright.

Here, let’s take a look at Taihe Music Group, which is the "music copyright dynasty" in mainland China besides the big three, Fumao and Emperor. Taihe owns a company called ocean butterflies, and Vae, the big three QQ music company, has joined ocean butterflies for more than 10 years. The elephant intangible music, which is a partnership between Silence Wang and Xu Liang, is also distributed by ocean butterflies in the mainland. Boy, I didn’t expect the big three QQ music companies to become half Netease cloud music people.

In September 2019, Ali won the koala and Netease Cloud Music, and the same year was also the moment when Netease Cloud ARPPU broke out.

Judging from the time nodes of these investments, Netease Cloud really bears the "music renaissance" plan of Ali and Baidu.

　If you want to make money, don’t be a second-hand dealer.

Even Baidu and Ali are desperate for blood transfusion. In terms of copyright, Netease Cloud Music is still in a weak position.

There was such a hot comment in the comment area of Netease Cloud Music, which impressed the author deeply: "I like this community very much. There are touching comments, song lists with personalized recommendations, and bosses full of ghosts, but I finally turned on QQ music because … I want to listen to songs."

Netease Cloud Music has a very high user viscosity and feelings, and the other has a very high resource library and copyright, so the two sides are locked in a fight for users.

At first, the National Copyright Administration seemed to want to give Netease Cloud Music a chance. In October 2015, the National Copyright Administration promoted the strategic cooperation between Netease and Tencent, and QQ Music granted 1.5 million music copyrights to Netease Cloud Music.

However, these 1.5 million songs did not bring reconciliation, but made the record companies in the copyright war suddenly have the right to speak, and the copyright fees also rose, and the online music platform had to fall into an evil.Sexual cycle: buy copyright to attract users → get user traffic and membership benefits → buy copyright again → suck traffic again.

In essenceGenerally speaking, this cycle is not much different from the "second-hand peddler" who pours watermelons at the head of the village, and the right to speak is not in his own hands. The copyright fee is also a "big killer" that has always caused Netease Cloud’s gross profit margin to be negative and lost 7 billion yuan in the past three years. If Netease Cloud wants to make money in music, there is only one way to go-to be the "father" of the record company.

The position of the online music platform in the music market now is equivalent to the ancient "video store", but the video store at least has bargaining space for purchasing goods, but the music platform does not. Therefore, only by getting involved in music production and disintermediation can the music copyright be directly in your own hands and reduce the commercial pressure.

In terms of user quality, Netease Cloud Music should have a lot of music consumption potential, because it currently has 181 million people a month, 89% of whom were born in 1990 and later, and it has Netease’s social genes and a strong social atmosphere.

On the production side of music, the platform can help the pricing and distribution of music copyright, and the reference information is divided into the author’s mode, which adopts the guaranteed+divided mode; On the sales side, the music platform can also sell music copyrights or distribute and underwrite music, such as accessing advertisements, pre-installing mobile phone terminals, smart speakers, smart cars, providing music for short videos, games and other companies, etc. This is the direction for music to make money.

Although Netease Cloud has begun to take this road, it is a long way to cultivate a Jay Chou who can take away tens of millions of users among its original musicians, and it depends on luck. After all, it took decades for the Chinese music scene to produce a Jay Chou.

Of course, if this road goes well, the future music platform will not have to bear the pressure of high copyright fees, and at the same time it will be able to share the cake in the music copyright market. Independent musicians are also expected to earn the dividend of paying for listening to songs, and the entire music industry chain will be boosted.

　Netease Cloud lost Jay Chou, but Netease Cloud "Jay Chou per capita".

After losing the copyright, Netease Cloud Music can make money for music projects by cultivating independent musicians and community culture, which can achieve the effect of "Netease Cloud is Jay Chou per capita", which may be its best result on the music road.

But Netease Cloud Music is still a tangled body in the eyes of many users.

What do users hate most? I hate you talking about money with him, especially users in minority communities, such as Douban, and Netease Cloud Music, which has a seven-point ideal and three-point business. Users who don’t hate you talking about money with it will stare at how you spend money. For example, some users vomit: "Netease Cloud Music does H5 to spread every day. Isn’t it good to buy two more songs with that money?"

Therefore, Netease Cloud Music should balance the user’s experience and the crux before the money-making project, so as to prevent users from losing because they feel that Netease Cloud Music "lost its original heart", otherwise, not to mention the Jay Chou per capita, even the effect of Pangmailang per capita will not be realized, after all, the community is still very pure.

In addition, for Tencent Music, which is listed on the US stock market, the highest price of Netease Cloud listed on the Hong Kong stock market is as high as HK$ 330, while the current share price of Tencent Music is only a dozen dollars. In the music market, is "Jay Chou per capita" overvalued? Or is owning Jay Chou undervalued? Let investors vote.

The original distressing Jiushu 39 Health Network

In the group match of Asian Youth Badminton Championship on June 30th, 17-year-old Zhang Zhijie of China Badminton Team suddenly fainted and died after being sent to hospital for rescue.

According to the press conference of Indonesian Badminton Association on July 1st, the treatment and examination results of Air Force Central Hospital and Central General Hospital showed that Zhang Zhijie died of sudden cardiac arrest.

In the face of sudden bad news, many teammates of Zhang Zhijie expressed their condolences over his death. Some teammates said that "Zhang Zhijie was in good health at ordinary times and had never heard of any diseases".

The death of such a young and promising child is really sad, and his departure also reminds us that even people who seem to be healthy at ordinary times may die suddenly.

This has a great relationship with the reasons behind sudden cardiac arrest.

Cardiac arrest refers to the sudden stop of the heart, which leads to the interruption of blood circulation, and the organs of the body can not get enough oxygen and nutrition. If not rescued in time, the patient will soon die.

This is often the main cause of sudden cardiac death.

According to China Cardiovascular Disease Report, about 544,000 people die of sudden cardiac death (SCD) every year in China, which is equivalent to one person dying of cardiac arrest every minute.

Because of the rapid onset and unpredictable onset time of sudden cardiac death, sometimes people around you will be gone before they can react, so it is very important to understand its inducement, symptoms before coming and preventive measures.

Although sudden cardiac death is urgent, it is not completely untraceable. Today, Uncle Jiu came to explore the "trace" of sudden death.

During strenuous exercise, the myocardial oxygen demand increases, which will aggravate the heart load. If the cardiovascular function is inherently impaired, it is easy to cause oxygen imbalance, myocardial necrosis, and eventually lead to sudden cardiac death.

In addition, long-term or strenuous exercise may also lead to a lot of sweating, which in turn leads to electrolyte imbalance, especially the loss of potassium and sodium ions, resulting in hypokalemia.

Once patients with myocardial infarction are complicated with hypokalemia, it is easy to cause malignant arrhythmia, such as ventricular tachycardia or ventricular fibrillation, which leads to a sharp drop in blood supply and even cardiac arrest. Sudden cardiac death is easy to occur if the rescue is not timely.

Clinical data show that hypokalemia is the most common cause of sudden death in badminton or marathon.

A study of 5,516 cases of sudden death in chinese journal of critical care medicine in 2020 found that sudden cardiac death was the primary cause of sudden death, accounting for 57.76%.

The second place is emotional excitement, accounting for 25.66%.

When angry, the blood flow of the heart doubles than usual, the contractility of the heart is strengthened, the heartbeat is accelerated, and a large amount of blood rushes to the heart, which is easy to induce angina pectoris and myocardial infarction, and then lead to sudden death.

Modern people have a fast pace of work, great pressure in life, and often stay up late to be a demon, which is easy to make their bodies overworked.

At this time, the body will continue to be tense, the nervous system is also highly tense, and the sympathetic nerve has been stimulated, thus raising blood pressure and increasing the burden on the heart.

Overwork can also lead to an increase in heart rate and increase the oxygen consumption of the heart, which may lead to acute myocardial infarction in severe cases and then sudden cardiac death.

Sudden cardiac death is closely related to heart problems, so people with cardiovascular diseases are more likely to be targeted.

If suffering from coronary heart disease, it will cause myocardial infarction, leading to myocardial necrosis and cardiac dysfunction;

Cardiomyopathy makes the structure and function of myocardium abnormal, which increases the risk of arrhythmia and sudden cardiac arrest.

Severe arrhythmia, such as ventricular fibrillation and ventricular tachycardia, can make the heart lose its effective pumping function, lead to insufficient blood supply and eventually lead to sudden death.

Conditions such as congenital heart disease and myocarditis can also lead to similar heart events.

Therefore, people with basic diseases should especially take care of their hearts.

For young people, the main causes of exercise-induced sudden death are coronary heart disease and hypertrophic cardiomyopathy. In addition, excessive tension, excitement, fatigue and other factors will also increase the risk of sudden cardiac death in young people.

Middle-aged people, especially those aged between 30 and 63, are often at high risk of sudden cardiac death. Because of the pressure of work and life, staying up late and working overtime, irregular diet and other factors, they are more prone to coronary heart disease.

Older people are more susceptible to myocarditis, heart failure and other diseases, which will lead to the gradual decline of heart function, thus increasing the risk of sudden cardiac death.

Although sudden death is urgent and heavy, it often sends us a distress signal before it happens, which must not be ignored.

If you have severe, tight and crushing pain in your chest, you need to be vigilant when you feel like your chest has been squeezed repeatedly and you feel suffocated.

Chest pain is also a typical manifestation of coronary heart disease, which generally occurs behind the sternum. More attention should be paid to this situation.

Our emotions will also protect our bodies. If there is a sense of panic at this time, don’t ignore the "alarm" of your body. No matter what you are doing, stop and observe immediately.

In addition to chest pain, in the absence of injury or illness, shoulders, chin, throat, teeth appear pain, and sometimes feel depressed, this situation should also be vigilant.

If a patient with hypertension suddenly has severe headache or even vomiting, it is necessary to highly doubt whether a cerebrovascular accident has occurred, and beware of sudden death.

In addition to pain, if there are obvious cyanosis, purple lips and decreased blood oxygen, it is highly doubtful whether there is pulmonary embolism.

Acute pulmonary embolism, if not handled properly in time, will easily lead to pulmonary infarction, blood circulation disorder and sudden death.

On the premise of no lack of sleep, strenuous exercise or illness, there is an unrelenting sense of fatigue for days, weeks or even months.

And accompanied by insomnia, anxiety, waking up at night and other symptoms, it is necessary to consider whether there is a heart problem.

Before sudden cardiac death, many patients will have a lot of cold sweat, which is one of the typical manifestations of myocardial infarction.

If you don’t have a history of heart disease, but suddenly you have sweating, palpitation, chest pain and other symptoms, you must not be careless, and you must see a doctor in time.

First of all, take responsibility for your health.

Maintain healthy living habits, feel your physical condition with your heart, and be alert to every alarm signal.

When you feel chest tightness, chest pain, dizziness and unknown pain, it is the body that reminds you that it is time to rest. Don’t sacrifice your life in pursuit of temporary efficiency.

Sedentary people should also pay attention to standing up and walking every hour or two, which can effectively promote blood flow in the legs and avoid pulmonary embolism.

Second, pay attention to your emotions.

If you know that you are angry, angry, grumpy and emotional, you should control it properly and find the right way to relieve your emotions.

Take things slowly, sometimes it will be faster.

If you find that you have signs of sudden death, don’t panic, rest quietly first, lie down when you are comfortable, and sit when you are comfortable, but don’t move unless necessary.

If there is oxygen inhalation equipment nearby, you should take oxygen as soon as possible with the help of your family or people around you.

At the same time, take the first-aid medicine that you carry with you immediately, such as chewing nitroglycerin and putting it under your tongue.

Patients with angina pectoris can usually relieve their pain in about two minutes. If the effect is not good, they can take a piece of nitroglycerin under their tongue 10 minutes later and call 120 emergency number quickly.

Finally, if you have spare capacity, you may be able to do your part by learning some first-aid skills when people around you suddenly fall to the ground and have signs of sudden death.

A report published in Military Medical Research shows that after cardiac arrest, the recovery rate of heartbeat can reach 41.7% if the rescue time is within 0~5 minutes; However, if the rescue time is within 5~10 minutes, the recovery rate of heartbeat is only 14.3%.

Therefore, in the first aid of sudden death, there has always been a saying of "golden four minutes". If we can grasp these few minutes, it is likely to save a life.

First aid can be done according to the following methods:

First of all, don’t carry or shake the patient, let him lie on his back on the ground, then pat the patient on the shoulder and call ta loudly.

Then observe the patient’s breathing: whether there is wheezing or abnormal breathing in the chest or abdomen (no more than ten seconds).

At the same time, touch the carotid artery for pulsation (non-medical personnel do not need to judge). At the same time, call for help loudly, and designate the personnel present to dial 120 emergency number. When there are no personnel present, call them quickly and keep effective communication with the medical staff in the emergency center.

If the patient is unconscious and his breathing and pulse disappear, chest compressions and artificial respiration should be performed immediately.

Pressing method: straighten your arms, one palm is close to the patient’s chest wall, the other palm is placed on the back of this hand, your fingers are crossed and held up, and the roots of your palms are forced.

Pressing position: the midpoint of the connecting line between the two nipples.

The compression amplitude and frequency are: the sternum sinks 5 ~ 6 cm (adult), and the chest fully rebounds after each compression, and the hands do not leave the chest wall, and the frequency is 100 ~ 120 times/minute.

按压时间与放松时间各占一半，放松时掌根部不要离开胸壁，以免按压点移位。

必要时进行人工呼吸：清理气道异物，仰头提颏法开放气道，一手捏鼻，嘴巴张大包紧患者嘴唇进行缓慢持续1秒钟吹气，吹气时余光观察患者胸廓是否微微起伏，放松捏鼻再次进行吹气。

按压和通气比例为30∶2，按压30次，人工呼吸2次，按压和人工呼吸5个循环后重新评估患者的意识、呼吸和脉搏。

*注意在开放气道的同时应用手指挖出病人口中异物或呕吐物，如有假牙者应取出假牙。

最后，如果旁边有自动体外除颤器（AED）就最好了。

设计AED的初衷就是让任何一个人都能毫无门槛地操作。因为情况紧迫，没有给人看说明书的时间，所以打开电源开关后，AED都是有语音提示的。

最后的最后，虽然九叔写文辛苦，但真心希望大家在生活中不会遇到上面的情况。

In addition to improving body muscle shape, exercise is more an effective health intervention, which is related to the reduction of the risk of chronic metabolic diseases such as obesity, diabetes and cardiovascular diseases.

However, it is easy to say that "exercise is good for physical and mental health", but it is difficult to explain the mechanism. There are still many unsolved mechanisms of exercise on systemic metabolic health. For example, a recent study shows that, but researchers have not directly proved the specific benefits of exercise to the liver [1].

This time, the team of He Congcong from Northwestern University found that the initiation of liver autophagy is a key link for exercise to bring systemic metabolic benefits.

Their research shows that exercise causes muscle to release a signal molecule called fibronectin 1(FN1), which reaches the liver through blood circulation and acts on α5β1 integrin on the surface of liver cells, thus triggering autophagy in the liver, thus improving metabolic health problems such as insulin sensitivity [2]. The article was recently published in the journal Cell Metabolism.

Screenshot of the first page of the paper

Autophagy abnormality has been considered to be related to many metabolic disorders in recent years. Previous studies have shown that exercise can induce autophagy in skeletal muscle of mice or humans through energy stress, oxidative stress and increase of intracellular Ca2+ level. In addition to these muscle tissues, many studies have shown that exercise can also activate autophagy in non-contractile muscle tissues such as liver, pancreas and adipose tissue, but the mechanism is still unclear [2].

Therefore, He Congcong and others deeply explored whether exercise can unlock the autophagy pathway of the liver and its role in systemic metabolic health.

First of all, they constructed a group of mouse models (ATG7Δliver) in which autophagy gene ATG7 was specifically down-expressed, so as to inhibit autophagy in liver cells.

Under the regular diet, the metabolic indexes of these mice are similar to those of wild-type mice. However, in the case of high-fat diet and running for 50 minutes every day, after 7 weeks, although the weight of the two groups of mice was similar, unlike wild-type mice, exercise did not save the glucose tolerance and insulin sensitivity of ATG7Δliver mice under high-fat diet.

These indicate that the improvement of metabolic health by exercise depends on autophagy of liver cells.

Exercise can’t save at G7 δ liver mice.

The results of in vitro experiments show that plasma and serum of wild-type mice can activate hepatocyte autophagy when they are in exercise, but plasma or serum at rest can not. In other words, there is a switch in the blood to turn on the autophagy pathway of the liver.

After protein’s proteomic analysis of the blood of mice, the researchers found that the level of fibronectin (FN1), an extracellular matrix protein that can be expressed by many types of cells, increased significantly in the blood of wild-type mice after exercise.

In addition, the experimental results in vitro showed that adding activator of AMPK, a cell energy sensor, to the culture medium could induce muscle cells to secrete FN1, but could not induce liver cells to secrete FN1. This suggests that the level of FN1 in blood is regulated by AMPK, and exercise may activate AMPK in muscle.

In the exercise state (when AMPK is activated), the extra FN1 comes from muscle cells, not liver cells.

In order to further study the role of muscle-derived FN1 in exercise, researchers specifically depleted FN1 (FN1(FN1Δmuscle) in mice muscles.

The results showed that the level of FN1 in the blood circulation of FN1Δmuscle mice did not increase after wheel running. Compared with wild-type mice, these mice did not get the improvement of systemic insulin sensitivity caused by exercise.

Specifically, the exhaustion of muscle-specific FN1 in mice did not affect its exercise-induced muscle autophagy, muscle morphology and exercise ability, and at the same time, the improvement of exercise-induced insulin signal transduction (activation of Akt regulatory factors) could be observed in its muscles. However, in this group of mice, the exercise-induced liver autophagy pathway was not activated, and no improvement in exercise-induced insulin signal transduction was observed in the liver.

These indicate that FN1 released by muscle is very important for the initiation of liver autophagy during exercise.

The depletion of FN1 in muscle affects liver autophagy.

From the mechanism point of view, during exercise, muscles secrete FN1, which leads to the increase of FN1 level in blood circulation. FN1 binds and interacts with α5β1 integrin in liver, activating IKK-JNK1-BECN1 signal pathway in liver cells, thus starting liver autophagy, promoting liver autophagy and reducing liver fat accumulation.

If the expression of α5β1 integrin in the liver of mice is inhibited, the weight, glucose tolerance and insulin sensitivity of mice can not be improved after high-fat diet and exercise, which proves the importance of α5β1 integrin -IKK-JNK1 pathway for the benefit of exercise-induced metabolism.

Overall, this study completed by He Congcong’s team shows that liver autophagy plays a key role in exercise-induced metabolic benefits, and reveals its mechanism. In addition, this study also shows that the metabolism of non-contractile muscle tissues such as liver can also be regulated by muscles.

Although there are only three models on sale at present, its M5/M7/M9 models are the top "players". For example, can you imagine a large SUV with a price of more than 470,000, but in May, it obtained the report card of sales data of more than 16,400 new cars? Therefore, with the empowerment of Huawei, the brand of the world can indeed be called a soul, which is exactly what other car companies envy.

No, after the new model, the new model and the customer M9, the customer brand will soon launch a brand-new customer M8 model. The new car is expected to provide a 5/6 seat layout, and the price we guess will start at around 350,000 ~ 400,000. If the price forecast comes true, then there will undoubtedly be opponents in this price range. Let’s take a brief look at it.

Judging from the spy photos exposed, the appearance of the asking world M8 is basically the same as that of the asking world M9. It is also an iconic family-style front face design and a penetrating taillight. The overall visual perception is not much different from that of the asking world M9, but it is slightly smaller than that of the asking world M9 in terms of volume sense, which is also the reason why the positioning of the two models is different.

The picture shows the M9 extended range version (left) and the pure electric version (right).

As for the interior, the M8 is expected to adopt the same interior design as the M9. The center console is composed of a large LCD screen, which looks highly integrated, and the interior should also be equipped with Huawei’s latest HarmonyOS cockpit.

Other configurations, such as rear projection, car refrigerator, 25-speaker HUAWEI SOUND sound system and ADS 3.0 smart driving, should also be available, so I don’t think friends who care about configuration and functionality need to worry too much. This M8 can definitely give it to you.

In terms of power, if there is no accident, the M8 should also provide extended range version and pure electric version for selection. Taking the M9 as a reference, its extended-range model is equipped with a 1.5T turbocharged engine and two front and rear motors, with a total power of 496 HP and a total torque of 675 Nm. The battery CTLC has a pure electric cruising range of 225km and 275km.

The pure electric version of the M9 is more simple and rude. The total power of the dual motors is 530 HP, and the maximum torque is 673 Nm. In terms of battery life, the CLTC of the pure electric version M9 has a pure electric cruising range of 630km and a battery capacity of 100kWh, using batteries from Contemporary Amperex Technology Co., Limited. However, there are only two versions of the pure electric version, and the lowest starting price has reached 509,800, so most users may still buy the extended-range version.

Finally, there is no doubt that the market share of the ideal L8 must be threatened by the arrival of M8. After all, regardless of the price, size, configuration and power form, the M8 seems to be chasing the ideal L8. Therefore, if this new car is really sold at a price of less than 400,000, then the ideal L8 obviously has a strong opponent.

In a word, the brand of Jiejie, which is empowered by Huawei, has already begun to show its edge. With the coming of another new model, Jiejie M8, we also believe that the new car will definitely catch fire after it goes on the market, don’t you believe it? Then let’s wait and see ~ (Text/Youshi Automobile Dazhuo)

A new invention: thermal liquid sensor was tested and verified in Chentian laboratory.

　　During the awarding ceremony of the 2017 Qiu Chengtong Science Prize, I talked with Professor Yao Qizhi, an academician of the Chinese Academy of Sciences, an academician of the American Academy of Sciences and a Turing Prize winner.

　　On the eve of the Spring Festival, Li Chentian, a 17-year-old high school student from Zhuhai, went to the United States at the invitation of Tsinghua University to participate in the "Global Innovation Experience Camp" jointly organized by Tsinghua and Washington University. He won the best project award in this innovation challenge by virtue of the "active high-voltage power line deicing monitoring system" invented on the spot. Later, he flew back to Beijing, as a participant in the last ISEF (International Science and Engineering Grand Prix), and introduced his experience to the young people who were participating in the 2018 ISEF project selection and international exchange winter camp.

　　He invented the fluorine-free electronic refrigerator at the age of 9, the solar intelligent outdoor manhole cover management system at the age of 12, and the programmable terminal and operating system at the age of 13. So far, he has nine national invention patents … What kind of "awesome person" is Li Chentian? Why have you achieved so much at such a young age? The all-media reporter of Guangzhou Daily takes you to know the young man who is praised by the outside world as "Edison" in China.

　　At the age of 5, I designed light-controlled lanterns for myself.

　　Last weekend, when the reporter saw Jerry Lee Tianshi, he wore an old school uniform and black-rimmed glasses, which was very low-key; He was a little shy when he didn’t talk, but when he started talking about his invention, Li Chentian hardly stopped for more than two hours, and he spoke as fast as a machine gun. When I met some professional terms, I was a little confused when I watched the reporter. He kept changing his body movements to explain it.

　　Li Chentian’s family said that his whimsy began in childhood. My father said that he showed a strong interest in electricity when he was learning English in the early morning. Every time he was carried out by his mother and saw the neon lights flashing on the street, he would dance. "How can anyone be on the TV?" "How can a toy car automatically turn?" ….. Since I was two years old, I have often asked my parents who are all from liberal arts to be speechless.

　　Because of her strong interest in electronic products, at the age of five, Chen Tian borrowed her cousin’s middle school physics textbook for self-study. On the Spring Festival that year, the family was going back to their hometown. Before leaving, they were worried that the red lanterns hanging on the balcony of Zhuhai’s home were left unattended in the morning. They had been on for more than ten days, which was both a waste of electricity and a fear of causing safety accidents. He sprouted the idea of designing a light-controlled switch. "It will automatically turn off the lights when there is sunshine during the day and turn on the lights at night when there is no sunshine." As a result, he removed a sensitive relay from a radio through two days of fiddling, and really made such a switch through transformation.

　　However, in the eyes of Chen Tian, the first real invention was the "fluorine-free electronic refrigerator" he built when he was 9 years old. Later, he was out of control. At the age of 12, he invented the "solar intelligent outdoor manhole cover management system", and at the age of 13, he developed the "programmable cloud-and-thing terminal and operating system" … At the age of 12, he won the first prize in the Guangdong Youth Science and Technology Innovation Competition for six consecutive years and won the national first prize three times. At the end of last year, Chentian won the Science Award and the Silver Award in Computer Science in the 2017 Qiu Chengtong Middle School Science Award Global Finals with his paper "Universal Power Adaptation Protocol (UPP) and Its Implementation". From provincial and municipal competitions to going abroad to represent China teenagers in ISEF, Li Chentian has won more than 30 scientific and technological innovation competitions, and has successfully applied for 9 national invention patents.

　　All whimsy comes from life.

　　"There is no epiphany in science. I just invested enough time in invention and creation. I just started the accumulation of’ 10,000 hours’ earlier." Li Chentian said modestly that to make inventions, we must first have a strong interest and then invest a lot of time.

　　Chen Tian said that you should be curious when making inventions and pay attention to everything that happens around you. All my whimsy comes from life. The idea of the project "Active High-voltage Power Line Deicing Monitoring System" when I participated in the Innovation Challenge in the United States originated from the ice disaster in 2008. He was deeply impressed by the embarrassing picture of manual mechanical deicing in the power sector on TV, so he always had an idea, "If the frozen wires can be deiced automatically, even the wires in the alpine zone can not be frozen!" Over the past few years, he has done a full technical demonstration for this project, and this global innovation experience camp just gave him such an opportunity. Chen Tian said, "Due to sufficient technology accumulation, the original prototype of this project took only two days, and finally won the highest award’ ‘Best Project Award’ in the participating projects."

　　The topic he is working on, "Variable Temperature and Pressure Pump", was inspired by his parents taking him skiing in Harbin during the winter vacation in 2016. At that time, he saw a small vendor barbecuing with liquefied gas on the street, and the fire went out. As a result, he saw the small vendor cover the gas bottle with a towel, pour some boiling water on the towel, and the fire "sprayed" again. He said that when he saw this phenomenon, he was very excited and thought that this phenomenon might solve the problem of transporting low-viscosity liquids such as refrigerants that he had always wanted to solve. If the pressure in the pump chamber is changed by changing the temperature instead of moving parts such as piston, wouldn’t it be possible to manufacture a pump without moving parts?

　　Parents support the "disruptive" behavior of disassembling and tampering with household appliances from an early age.

　　Chen Tian said, "If I make small achievements, I would like to thank my parents for their tolerance and support." Since childhood, his parents never forced him to attend interest classes, and he was not required to be a schoolmaster. He said that he has never attended any cram school since he went to school. During the holiday, he either stayed at home to make inventions or participated in scientific and technological competitions and exchanges in various places.

　　Parents also fully support the "disruptive" behavior of dismantling household appliances that they have shown since childhood. Just in the first grade of primary school, in order to study the temperature control switch, I dismantled a newly bought electric heating plate imported from Germany at home in the morning. At that time, the market price was more than 2,000 yuan. When he was 9 years old, he developed a fluorine-free electronic refrigerator. In order to buy a refrigerator, his parents took him to Beijing to find many shops, and finally spent three days scouring Zhongguancun for the desired products.

　　In order to support his son’s innovation and invention, his father set up a "morning lab" for him at home. In this laboratory, the reporter saw a laser positioning machine, a small supercomputer with 72 cores, a multifunctional calibration measuring instrument with data stability of 2ppm, a multifunctional vector network analyzer and a very advanced mixed-signal oscilloscope.

　　"Over the years, the equipment in this laboratory alone has invested more than one million yuan, not including thousands of old electronic products that he invents and buys every time and dismantles." Chen Tian’s father smiled and said, "If we only talk about the electronic laboratory, my laboratory may be the best in Zhuhai."

　　However, apart from scientific and technological inventions, Chen Tian has no other hobbies. As long as he doesn’t go out to participate in scientific and technological competitions and exchanges in his spare time, he basically stays in this laboratory.

　　Learning computer programming in the fifth grade of primary school is painful to cry.

　　Li Chentian does not agree with the reputation of the outside world as a "genius boy". His parents have repeatedly stressed that their children have only shown strong interest in electrical appliances and circuits since childhood, and they are ordinary teenagers. "He is only willing to spend time on electronics," my father said seriously. "Since I was a child, I love to disassemble things. Others sell old household appliances at home, and my family often buys them back from outside."

　　Chen Tian added that every design or invention is not always smooth sailing, and there are many failures. There are two or three thousand discarded circuit boards at home. And when learning theoretical knowledge, I once had the idea of giving up. With the deepening of scientific research, he had to learn computer programming for a project in the fifth grade of primary school. Most of the electronic components encountered before are concrete things, while computer assembly language is too abstract. For a child in the fifth grade of elementary school, it is like reading a gobbledygook at first. "If you don’t understand, you can’t learn!" Sometimes I read until late at night, and in the morning I said that I was so miserable that I cried and wanted to give up several times. Finally, with the encouragement of his father, he persisted, and it took him more than a month to write the first program-"digital clock". Looking at the success of the first string of code written by myself, Chentian jumped with excitement. "He was yelling, and then he ran downstairs from upstairs and kept shouting, Dad, I made it up." Dad recalled.
