"Today, my heart suddenly beats faster.

　　It is easy to get flustered when you move. "

　　"My heart is beating a little fast. Do you want to go to the hospital?"

　　… …

　　Recently, various statements circulated on the Internet.

　　Arouse a new round of worries of "Yangkang people"

　　The topic of "Beware of viral myocarditis after yang"

　　Once rushed to the top of the hot search list.

　　Jin Dongyan, a virologist and professor at the School of Biomedicine, Li Ka-shing Medical College of the University of Hong Kong, told the reporter that acute myocarditis really needs attention among the complications of COVID-19.

　　What disease is myocarditis?

　　According to Beijing Daily, myocarditis is an inflammatory lesion of myocardium, which can be caused by infection (such as viruses, bacteria or fungi) or non-infection factors (such as autoimmune diseases), among which various viruses causing intestinal and upper respiratory tract infections are the most common.

　　Clinically, myocarditis is mostly caused by virus infection, and the common cold can also be induced.

　　Myocarditis can launch an "indiscriminate attack" on people of all ages and sexes, but young people aged 20-40 are more likely to be recruited than the elderly and children.

　　After the virus enters the blood, it reaches the heart with the blood circulation. If the patient’s resistance is weak, it may cause myocarditis. Viral myocarditis refers to acute or chronic inflammatory pathological changes caused by viral infection, which belongs to infectious myocardial diseases.

　　Viral myocarditis has the following manifestations according to the severity:

　　Early myocarditis: manifested as fatigue, chest tightness, shortness of breath, palpitation, dizziness, loss of appetite, nausea, vomiting, dyspnea, chest pain, etc.

　　Mild viral myocarditis: symptoms such as arrhythmia, tachycardia or bradycardia appear, and myocardial ischemic changes can generally be found by ECG;

　　Severe viral myocarditis: the condition is dangerous, and the mortality rate is extremely high, which can reach 70%~80%, and death or sudden death occurs within hours or days.

　　Is the heartbeat accelerated after "yang" because of myocarditis?

　　Why do many people’s hearts beat faster after "yang"? There are eight possibilities:

　　1. fever

　　Every time the body temperature rises by one degree, the heart rate increases about 10 times/minute. If accompanied by symptoms such as chills and shivering, the heart rate may increase even more. After the body temperature drops, the heart rate will slowly return to normal.

　　2. All kinds of drugs taken

　　Some of the drugs used to relieve symptoms may cause the heart rate to increase. For example, caffeine and aminophylline in cough medicine, antiasthmatic medicine, some drugs inhaled by atomization, etc. These drugs can relieve symptoms, but they can’t kill the virus. Therefore, you should take medicine when there are obvious symptoms, otherwise taking medicine will not help much.

　　3. Physical reaction of hypovolemia

　　After infection, due to insufficient food, diarrhea, vomiting, infection or gastrointestinal reaction caused by drugs, it may lead to a certain degree of hypovolemia, and the heart rate will be compensated and increased.

　　Therefore, during the period of infection, we should appropriately increase drinking water, eat less and eat more meals, and even drink oral rehydration salts. Be alert to dehydration and seek medical advice in case of thirst and oliguria.

　　4. All kinds of pain may also cause the heart rate to increase.

　　Many people have experienced various pains after being infected with COVID-19, such as "craniotomy above, leg sawing below, waist cutting behind, laparotomy in front, and throat cutting with a knife", which is enough to stimulate the heart rate to increase.

　　5. Body’s stress response to virus infection

　　After being infected with the virus, the human immune system is activated, and the immune activation itself may be accompanied by an increase in basal heart rate.

　　6. Severe hypoxia

　　This is a relatively serious cause of rapid heart rate increase, usually accompanied by shortness of breath, severe cough, lung image changes, etc., commonly known as severe infection. According to the national diagnosis and treatment standards, if the respiratory rate exceeds 30 beats/min and the blood oxygen saturation continues to be lower than 93%, you should be careful of severe infection.

　　7. Accelerated heart rate induced by aggravation of basic diseases.

　　For example, patients with basic chronic obstructive pulmonary disease (commonly known as emphysema) and patients with basic heart disease (especially chronic heart failure) should be paid attention to if there is sustained increase in heart rate in these patients. The more obvious the heart rate increases, the more dangerous the condition may be. You should go to the hospital for examination and evaluation as soon as possible.

　　8. Myocarditis

　　Like other viral infections, Omicron has a certain probability of inducing myocarditis after infection. However, myocarditis usually occurs in the late stage of virus infection or 1-2 weeks later, which is related to virus-related immune response. In addition to the increase of heart rate, ECG will change and myocardial markers will increase significantly.

　　What circumstances should be suspected of viral myocarditis?

　　Pan Hongying, director of the Infectious Diseases Department of Zhejiang Provincial People’s Hospital, said that the course of myocarditis may last for hours to months, and serious complications such as cardiac arrest caused by dilated cardiomyopathy or heart failure.

　　If you have discomfort such as palpitation, chest tightness and shortness of breath, you need to be vigilant. It is recommended to seek medical advice in time, have an electrocardiogram and blood test. Generally, young people who love to stay up late are more likely to get fulminant myocarditis. If not found early, it will easily lead to cardiac arrest and multiple organ failure. It is suggested to rest, sleep more and not do strenuous activities within two weeks after infection.

　　Zhang Lei, deputy director of the Respiratory Department of Shanghai Children’s Medical Center affiliated to Shanghai Jiaotong University School of Medicine, said that it is necessary for the recovered people in COVID-19 to rest in 1-2 weeks. Zhang Lei said that after Covid-19’s infection, human immune function will appear obvious disorder, that is, the number and function of lymphocytes will decrease in the acute stage of infection, and then slowly return to normal with the recovery of the disease. Most people will have this "immune disorder period" lasting for 1-2 weeks. During the period, other viruses, bacteria, etc. are very easy to take advantage of.

　　If you are isolated at home alone, it is best to keep in touch with friends and relatives around you at any time, so as to avoid discomfort and go to the hospital in time.

　　Can you get myocarditis immediately after Yangkang?

　　According to the Life Times, the online saying that "it is easy to get myocarditis after recovering from yang kang" is actually exaggerated.

　　Even if you suffer from myocarditis after "Yangkang", the more direct reason is that Covid-19 has invaded the myocardium, and exercise is a fuse. In other words, the virus can only cause myocarditis if it invades the myocardium.

　　Li Dong, the chief physician of the Department of Infectious Diseases of Beijing You ‘an Hospital, once said that after COVID-19 recovered, it would take a week or two for many people to return to their previous physical condition, and it was suggested not to take strenuous exercise in the early stage of recovery.

　　Xinhua News Agency, Beijing, December 2nd Question: How to prevent and treat children’s respiratory diseases? How to combine traditional Chinese and western medicine? — — National Health Commission press conference responds to the focus of prevention and treatment of respiratory diseases in winter.

　　Xinhua News Agency reporters Xu Penghang and Li Heng

　　Recently, the flu has entered the high season. How to prevent respiratory diseases in daily life? How to treat children with respiratory diseases? How does the combination of traditional Chinese and western medicine play a role in treatment? The National Health and Wellness Commission held a press conference on December 2 to respond to the focus of prevention and treatment of respiratory diseases in winter.

　　No new infectious diseases caused by new viruses or bacteria were found.

　　Mi Feng, spokesperson of the National Health and Wellness Commission and deputy director of the Propaganda Department, said that at present, the National Health and Wellness Commission, state administration of traditional chinese medicine and the National Bureau for Disease Control and Prevention continue to carry out monitoring and judgment of respiratory diseases in winter, and make arrangements for adjusting medical resources, optimizing medical treatment procedures and giving full play to the role of traditional Chinese medicine.

　　Mi Feng said that according to the monitoring, all the current acute respiratory diseases are caused by known pathogens, and all of them have corresponding mature treatment methods, and no new infectious diseases caused by new viruses or bacteria have been found.

　　"We have been conducting mutation monitoring." Wang Dayan, director of the National Influenza Center of the Institute of Virology, China CDC, said that the monitoring results show that influenza viruses are sensitive to several current anti-influenza drugs, which means that anti-influenza drugs are effective against influenza viruses.

　　Vaccination against influenza can effectively reduce infection.

　　At present, the flu has entered the high season. Is it too late to get vaccinated now? Wang Dayan said that influenza vaccination is still effective for people who have not been vaccinated before, and it is recommended that you get the flu vaccine as soon as possible.

　　"Practice at home and abroad has proved that using vaccines is one of the most economical and effective preventive measures." Wang Dayan said that as long as it is vaccinated in professional institutions as required, it will have good results, especially for the elderly and children. They should actively vaccinate against influenza to ensure a normal pace of life and study.

　　Wang Dayan suggested that in daily life, we should wear masks scientifically, develop good personal hygiene habits, develop a healthy lifestyle, actively vaccinate and do a good job in self-health monitoring. If there are symptoms of respiratory infection such as fever, cough and sore throat, it is recommended to stay at home as much as possible and avoid going to crowded places. If you really need to travel, pay attention to wearing a mask to prevent the disease from spreading to others.

　　Give full play to the characteristics of traditional Chinese medicine and take many measures to strengthen the prevention and treatment of respiratory diseases in children

　　Recently, state administration of traditional chinese medicine issued the Notice on Further Strengthening the Construction of Pediatrics in Chinese Medicine Hospitals to promote the expansion and hierarchical development of pediatric medical resources in Chinese medicine as a whole.

　　Xing Chao, deputy director of the Department of Medical Administration of state administration of traditional chinese medicine, said that state administration of traditional chinese medicine is guiding Chinese medical institutions at all levels to strengthen resource coordination and strengthen the staffing of fever clinics, emergency departments, pediatrics and respiratory departments, and to meet children’s medical needs to the greatest extent by opening more clinics, extending outpatient hours, opening night clinics and weekend clinics, and providing "internet plus" diagnosis and treatment services.

　　Liu Qingquan, president of Beijing Hospital of Traditional Chinese Medicine, said that some Chinese medicine hospitals began to adjust the layout of pediatrics, increase the area of pediatrics and extend the duration of consultation. In view of children’s fever, cough, expectoration, diarrhea, etc., Chinese medicine hospitals at all levels have launched standardized and scientific videos through websites for parents and guardians to learn from.

　　Recently, in some places, the number of cases of children’s respiratory infection has increased significantly, and some children will develop bronchitis and pneumonia. In this regard, Wu Liqun, director of the Pediatrics Department of Oriental Hospital of Beijing University of Chinese Medicine, said that children’s acute respiratory infections belong to the category of colds, coughs and pneumonia. Chinese medicine believes that such diseases are caused by exogenous pathogens invading the human body, resulting in dysfunction of viscera and lung damage. Symptoms such as fever, stuffy nose, runny nose, sore throat, cough and expectoration occur.

　　Wu Liqun said that in the treatment of such diseases, Chinese medicine will differentiate syndromes and treat them accurately according to the different causes, symptoms and physical characteristics of children. For the early stage of respiratory tract infection, children mainly show symptoms such as fever, runny nose, sore throat and cough. The treatment methods of dispersing lung, relieving exterior syndrome and relieving sore throat are mainly adopted, and at the same time, according to the characteristics of children, the appropriate external treatment methods of traditional Chinese medicine are combined. In the recovery period of the disease, some children have symptoms such as cough, fatigue, poor appetite, etc. Traditional Chinese medicine adopts the treatment methods of invigorating spleen and resolving phlegm, tonifying deficiency and strengthening body resistance.

　　

The prisoners organized a small band to play songs (Source: Beijing Evening News)

The prisoners are feeding rabbits (Source: Beijing Evening News)

　　　　It is located at the foot of the Great Wall and beside the Guishui River, where the vegetation is lush and the flowers are delicate and charming. However, the unique symbols of the sentry standing guard and the high-wall power grid make all the plants and trees here wear solemn and mysterious veils. As a special prison in Beijing’s prison system, Yanqing Prison specializes in holding old, sick and disabled criminals. Among them, more than 100 male psychopaths in Beijing are concentrated here. Manic, depressed, paranoid … almost all kinds of mental disorders exist. They are prisoners and patients, so it is difficult to manage and treat them. How can these special prisoners reform and cure their mental and spiritual diseases? With all kinds of questions, the reporter walked into the 11 th section of Yanqing Prison yesterday.

　　Psychopaths are afraid of boredom and trouble.

　　　　There is a classic mental hospital scene in the Chinese New Year blockbuster "Big shot", in which patients are either rolling around or shooting with their mouths full, which makes people laugh and cry. However, as soon as he entered the gate of the sub-prison, the reporter was surprised that not only did he not see the noisy and noisy scenes in the movie and imagination, but it was so quiet that people questioned whether there were really more than 100 mental prisoners living here. Prisoners look no different from normal people. Six people live in a cell, reading, resting, tidying up the house or strolling in the tunnel.

　　　　The reporters were greeted by Shen Bingyu and Zhu Kuncheng, two district heads of sub-prisons, who worked together in the psychiatric ward for five years. Many people don’t understand that mental illness can be exempted from criminal responsibility, and how can it be put in prison? Shen Jian’s introduction first explained this problem to the reporter: "The mental patients here are mainly intermittent mental illness, and they belong to people with limited capacity. They are prisoners who are given a lighter or mitigated punishment according to law, and 70% are heavy criminals with no life and suspended death. The remaining part is mentally ill after entering prison because it can’t adapt to the life of losing freedom. "

　　　　"These more than 100 mental patients are divided into three types: treatment period, rehabilitation period and stable period. For us, prisoners who are getting sick and noisy are the easiest to manage." Shen Jian’s words were very unexpected to the reporter. He explained: "For example, we have a prisoner here who is schizophrenic. After he was in prison, he was transferred to prison four times and committed suicide four times. He hit his head anytime, anywhere and unconditionally, and he was transferred to our prison area with a helmet. Diagnosed by the doctor, he suffers from schizophrenia and bipolar affective psychosis of mania and depression. In a situation like this, we can only give him medicine first and restrain him with medical measures. It is those who are silent and can’t see the signs that make people nervous. "

　　　　Zhu Jian said that a prisoner was very normal when talking with the police. After talking, he got up and bowed to the police and said thank you. But at this moment, he turned and started to run outside, and the captain chased after him, running away with his shoes. Finally, he caught him at the gate of the prison area. "Psychiatric prisoners have strong concealment, so in addition to full-time psychiatrists who are responsible for treating them here, we have also set up a system of nurses on duty. Let healthy, well-behaved prisoners be caregivers, patrol the tunnel with the police for 24 hours, report any abnormality immediately, stop and control the situation in time for suicides, injuries and other diseases, or double-monitor. In order to ensure the safety of prisoners, the heating in the cell is wrapped, and the windows and doors are pasted with stickers to prevent them from breaking into sharp weapons after impact.

　　Let "dumb" criminals speak

　　　　Because of their special diseases and crimes, some mental prisoners are not tolerated by society and some are despised by their families, but it is precisely in prison that no one is abandoned. I wish the warden gave an example to the reporter: Wang, a prisoner, was already suffering from schizophrenia when he was transferred to Yanqing prison. He was very withdrawn and never spoke. Every time his father came to the prison to meet, the two men held the phone face to face, and his father kept talking. Wang never said a word. When the father finished speaking, the two men put down the receiver and sat opposite each other until the end of the meeting time. Many people think that he is a mute.

　　　　After asking Wang’s family, the police learned that Wang had been able to speak before, and he had not spoken for three years since he got sick. The affirmation of family members gave the police motivation. Later, the police consciously approached him, cared about his life, talked to him every day, and asked the prisoners in the same group to talk to him. Although they didn’t hear Wang say a word, the police always felt that they could make him speak like a normal person.

　　　　During his time in prison, Wang was also observing the police. He found that he was not bullied, and no one looked down on him. The concern of the captain also made him feel very warm. But after all, I haven’t spoken for three years, and I have to use a special method to make him speak. When the captain was on a patrol, he suddenly called his name in front of Wang, and Wang actually subconsciously answered "to". This word is not only an inspiration to the police work, but also breaks the barrier of Wang’s autism. Although the language function has been seriously degraded, Wang gradually resumed his desire to communicate. For example, knocking on the table is called "Captain Mu", and drinking water represents "Captain He". When he saw his father again, Wang first called "Dad" and then reported his life in prison to his father. The father who hadn’t heard his son talk for more than three years suddenly burst into tears.

　　The courage to let the sick man regain his life.

　　　　Shen Jian said that because these prisoners have long prison terms and suffer from mental illness, many people are prone to suicidal thoughts because they hurt their families. Therefore, while treating their diseases, the police should also help them find the courage to live again.

　　　　The prisoner Liang once participated in the theft and escaped. After committing the crime, he "flew" outside for more than a year. During his escape, he panicked every time he heard the siren. The fear of fleeing eventually made him suffer from mental illness. After being reported, Liang was arrested and sentenced to 15 years. After entering the psychiatric ward, Liang secretly picked up a piece of broken glass from the ground when he released the wind, which was discovered by the police in time. The police asked him what he was going to do, and Liang said that he wanted to cut his pulse and commit suicide at an appropriate time. During the conversation, the police learned that he liked sports and "excited" him to say, "Do you dare to compete with me in basketball?" At first, Liang felt that the police were joking with him. Who knows that he was really recruited into the basketball team in the prison area and often participated in some sports activities. Through physical exercise, Liang’s spirit is getting better and better day by day, and people are much more excited, restoring the vitality of young people, and he has never been ill until now.

　　　　Appreciation and encouragement is a principle of reforming prisoners in psychiatric ward. Zhao, who is working as a nurse for sick people in the prison area, was sentenced to death with a suspended sentence for robbery. He always felt that he could not walk out of the prison door alive, and every day he clamored to pull him back and shoot him. The police and paramedics watched him for 24 hours. In contact again and again, the police realized that Zhao did not really want to die, but was desperate for the prison life in the second half of his life. "He has the skill of haircut and has to give him a chance to restore his life." The police asked him to use his skills to give haircuts to other prisoners every Saturday. Zhao not only felt that life had hope, but also became a nurse for sick people after two years.

　　Enjoy beautiful scenery, listen to music, raise small animals and cultivate healthy personality

　　　　It is not the purpose of the prison to just watch over the accident. The prison for mental patients is to restore the healthy personality and self-control of mental patients on the basis of stability and by means of correction, and then put them into reform after self-restraint. For this reason, the police have not tried to find a way.

　　　　There is a warm name-"Love Paradise" in an open space surrounded by iron nets in the center of the prison area. More than a dozen "big mushrooms" of various colors are Bunny’s dormitory, where prisoners raise small animals, enjoy beautiful scenery and listen to music, so as to resolve bad emotions, cultivate normal thinking and restore healthy personality. In addition, the prison has invested a lot of equipment to establish a chess room, a reading room, an audio-visual room, a physical therapy room, an arts training room and an agricultural therapy base. These five rooms, one park and one base have become the most distinctive places for the rehabilitation of mental patients. "Prisoners are now playing bridge, and the level of Go is also the highest in Yanqing Prison. Healthy chess activities are helpful to their thinking and intelligence; They have also formed a small band, which is practicing songs these two days and will tour in various prison areas next month; The vegetables in the agricultural treatment base should also be mature. Although the output is small, giving each of them a tomato can be regarded as the fruit of their labor. Through a variety of corrective methods, the proportion and incidence of unstable conditions of mentally ill prisoners have dropped significantly in recent years. " Shen warden said with a big smile.

　　　　Looking at their healthy and active lives, it is really hard to imagine that these are all mental patients. They lost their freedom here and secretly repented for their irreparable mistakes; But it is also here to regain dignity and find a healthy life in the people-oriented management mode of prisons. Although the reality that the reporter saw was not as exciting as expected, but calm and serene, and the police were not imposing but amiable, this is the image of a modern prison and the best evidence that this special prison area has not had an accident for more than ten years.

　　If you ask a candidate who has just finished the college entrance examination, what is "machinery"? Perhaps the answers will be "gear", "lathe in the factory" and "robot", and at the same time, we should think of the impressions of "wide application" and "everywhere in production and life".

　　Before learning machinery, Zhuang Zheming’s concept of machinery came from the cartoon "Transformers" he saw when he was a child. He chose the major of mechanical design, manufacturing and automation in the School of Mechanical Engineering of Tianjin University with a vision for robots. He graduated this year and fulfilled his dream of "robot" with a graduation design work of "snake robot". This work also won him the first prize in the 13th Graduation Design Competition.

　　Let the students who have just entered the school gate and are still a little ignorant about the concept of mechanical discipline know more about the connotation of machinery when they leave the school gate, and plant a seed of "big machinery" that is "new and new" through "professional blending and advantage integration", and have the ability and experience of innovation and entrepreneurship, which is the concept and practice of "3 integration and 4 behavior" talent training exploration in the School of Mechanical Engineering of Tianjin University.

　　"Three-in-one and four-in-one" means to further emphasize and attach importance to the cultivation of compound and innovative talents on the basis of the traditional training objectives of knowledge, ability and quality, put forward the reform concept of integration, sharing and innovation, construct the "three-in-one" guarantee system of professional integration, resource integration and teacher integration, and explore the "four-in-one" training mode with team as the body, scientific research as the source, innovation as the foundation and entrepreneurship as the purpose.

　　The dilemma of "3A College"

　　In Tianjin University, as a discipline established at the beginning of the school in 1895, machinery is an "old discipline" of the same age as the school. In the view of Wang Tianyou, president of the School of Mechanical Engineering, the development history of mechanical discipline in modern China has always stood at the forefront of history, but compared with a hundred years ago, "machinery" has undergone earth-shaking changes from the outside to the inside.

　　The three first-level disciplines of the School of Mechanical Engineering of Tianjin University: mechanical engineering, mechanics and power engineering and engineering thermophysics, were all rated as "A" in the fourth round of national discipline evaluation, so the School of Mechanical Engineering is also called "3A College" of Tianjin University. The college has four undergraduate majors: mechanical design, manufacturing and automation, engineering mechanics, energy and power engineering and industrial design. Each major has a unique historical advantage and a strong disciplinary advantage. "Just like the four brothers in a big family, they are all wonderful and all ‘ Take care of each other ’ Live happily. Daily teaching and student defense, including teachers, are very independent. " Talking about the situation of three disciplines in the college more than ten years ago, Cao Shuqian, vice president of the college in charge of teaching, said that this has caused some problems in student training, the most obvious of which is that students’ knowledge and ability are single, and their ability to cross and cross borders is not strong; The superior teaching resources are scattered, and the students’ innovation platform is poorly shared. However, due to the prevailing atmosphere of emphasizing scientific research over teaching in domestic universities at that time, teachers’ investment in teaching was relatively insufficient and they lacked initiative in teaching reform.

　　At that time, the speed of knowledge updating and interdisciplinary research in the international scope was accelerating, the coverage of major in mechanical engineering was getting wider and wider, and the development of new economy and new industry was changing with each passing day. There was an urgent need for compound and innovative engineering talents with cross-border and innovative ability. Obviously, the compartmentalized education and teaching organization model can’t meet the requirements of talent training.

　　Tear off the "label"

　　On the one hand, under the baton of scores, students’ enthusiasm for participating in innovative and entrepreneurial projects is not fully encouraged; On the other hand, the habitual identity consciousness of "you are mechanical", "I am dynamic" and "he is mechanical" has become an invisible "label" attached to teachers’ hearts, and teachers’ motivation for interdisciplinary teaching to cultivate talents is not recognized.

　　In order for teachers to devote more energy to undergraduate teaching and students to devote more energy to innovation, it is necessary to change the meaning of grades and tear off the inherent identity "label" in teachers’ hearts.

　　"The first thing to change is the meaning of the score." Cao Shuqian said that when there were only 2 credits in innovative courses at that time, the college increased the weight of scientific and technological innovation in students’ total scores, so that students’ scores were not only the exam results of the courses, whether in the evaluation of Excellence or in the insurance research. For example, the College issued the Implementation Measures of School of Mechanical Engineering of Tianjin University to Encourage Students to Participate in Extracurricular Science and Technology Competition (Trial), which clearly stipulates that undergraduates who won the top three awards in Class A projects during their studies (the weighted scores in the first three years were in the top 60% of their majors), undergraduates who won the top two awards in Class B projects and special group projects in Class C will be given extra points on the basis of the average weighting of students when they are exempted from graduate students. Award-winning for different projects can be accumulated separately. At the same time, the determination of the workload of competition instructors and the recognition and reward of competition award-winning instructors (coaching staff) have also been clearly defined.

　　"All courses are open and teachers are open. Which course do you want to talk about, after passing a series of processes such as training, assessment, class assistance, collective lesson preparation and trial class, you can join the teaching team of the course and walk onto the podium. " Cao Shuqian said, teachers of public courses in disciplines get through, teachers of cross-disciplines in colleges get through, and the professional/disciplinary boundaries are broken … … At the beginning of the reform, the college has set up 17 teaching teams, 35 responsible posts and backbone posts, and teaching posts in several disciplines. Teachers’ performance and promotion are directly linked to teaching. This kind of teacher team integration and curriculum integration, on the one hand, has realized the adjustment and optimization of teaching teachers according to students’ needs, on the other hand, has promoted teachers’ investment in teaching, guaranteed the construction of important teaching projects, and improved the teaching effect as a whole.

　　Blend and create new things.

　　The team of teachers in the college has been opened, and the problem of sharing teaching resources and innovation platforms has been solved. The scattered 19 teaching laboratories were integrated into 4 experimental teaching centers, of which 3 were approved as national experimental teaching demonstration centers; Establish two national engineering education practice centers; Six national excellent courses and resource sharing courses have been built, and a group of innovation and entrepreneurship platforms has been built. The integration of platform and resources provides students with a broader platform for innovation and entrepreneurship, and also allows students to feel the struggle of youth in the initial experience of innovation and entrepreneurship and find the future direction.

　　Liu Songtao, the founder of Chenxing (Tianjin) Automation Equipment Co., Ltd., founded Astro Boy, a high-end parallel robot brand, after studying in the School of Mechanical Engineering of Tianjin University for 7 years, and won the gold medal in the final of the 4th China "internet plus" University Student Innovation and Entrepreneurship Competition. Looking back on his own road of innovation and entrepreneurship, Liu Songtao believes that the experience of participating in the "Beiyang Power" team as an undergraduate made him experience the process of "entrepreneurship" for the first time. When he entered the laboratory in his junior year, he cooperated with his classmates to complete the research and development of a prototype of a new four-degree-of-freedom parallel robot product and won the first prize in the graduation design competition, which encouraged him to embark on the road of innovation and entrepreneurship.

　　Compared with the seniors, Zhuang Zheming, who won the first prize in the graduation design competition this year, has the same rich experience in innovation and entrepreneurship: IEEE China Robot Design Competition, National Mobile Internet Innovation Competition (University Group), First Prize of National Renewable Energy Science and Technology Competition for College Students and National Youth Environmental Protection Competition & HELIP; … For Zhuang Zheming, the process of participating in the innovation and entrepreneurship competition is a process of teamwork, continuous learning and self-enrichment.

　　"4 for" promising

　　"Students’ bi-design comes from scientific research, innovation (college students’ innovation and entrepreneurship training program) comes from scientific research, competition comes from scientific research, students’ cross-disciplinary team cooperation and teachers’ cross-disciplinary guidance run through the whole process of students’ innovative training, and students’ innovative thinking and ability as well as their ability to solve complex engineering problems are fully exercised." In Wang Tianyou’s view, the "four-for-one" training mode with team as the body, scientific research as the source, innovation as the foundation and entrepreneurship as the purpose provides an effective path for the training of compound and innovative talents of traditional engineering majors.

　　Today, as the first mechanical undergraduate graduation design competition in China, it has been held for 13 consecutive sessions, expanding from the original college to 14 universities in Beijing, Tianjin and Hebei and Central and East China. The entries involved more than 10 major mechanical engineering majors, including mechanical design and manufacturing and automation, industrial design, energy and power engineering, engineering mechanics, process equipment and control engineering, and thousands of students participated.

　　All students realize the cultivation of basic innovation by participating in teachers’ scientific research projects and carrying out graduation projects; Teachers extract innovation projects and discipline competitions from scientific research projects, and more than half of the students realize the promotion and innovation training by participating in innovation and competition projects; Some students extract entrepreneurial projects from big innovation and competition projects to create technology companies. Student innovation projects have increased from 37 in 2012 to more than 100 projects every year; Students independently set up scientific and technological entrepreneurial teams from scratch, and now there are 14 and 12 registered scientific and technological companies.

　　In the eyes of teachers and students, the training mode of "three in one and four in one" promotes the ability and level, and it is also the enthusiasm and passion for continuous innovation and entrepreneurship, which is the fashion password of century-old machinery. (Correspondent Liu Xiaoyan)

After Brazil reached the World Cup quarter-finals, I believe all Brazilian fans around the world share my feelings: it’s been 20 years, and it’s finally dawn.

Don’t think that abusing South Korea is nothing. Now the South Korean team is no longer Amon. Looking at today’s football, no team except Brazil can win so brutally, thoroughly and heartily against South Korea. France can’t, England can’t, and Argentina can’t, but Brazil, which vowed to win for Pele, who is seriously ill, can.

Being a Brazilian fan is a very unique experience. On the one hand, it is very cool. Every World Cup is a favorite to win the championship, and there are warm expectations every four years. On the other hand, it’s very painful, because Brazil always fails if it doesn’t win the World Cup, but winning the World Cup requires not only strength, but also various coincidences, so more often, Brazilian fans will end their mental journey of the World Cup in disappointment.

Brazil has not won the championship for 20 years. What happened to the Brazilian team in these 20 years? Let me give you a brief stroke.

In 2006, Brazil claimed to be the strongest in nearly 40 years. However, arrogant soldiers are bound to lose. Please go back to the iron coach Pereira, who can’t relax put in order’s tactical discipline. When Henry beat Brazil, Carlos, the world’s number one left-back, was tying his shoelaces. Let us remember this little bald head that makes people love and hate.

In 2010, Brazil, with dim stars but strong integrity, was the only team that ever beat Spain in the Confederations Cup. In the knockout against the Netherlands, it not only took the lead, but also completely controlled the situation. However, a guy named Melo suddenly went crazy, making an own goal before a red card. Let’s remember the name Melo.

In the 14th and 18th World Cups, Brazil really can’t do it. Neymar is the only one who makes waves in the attack line. In 2014, Neymar and Tiago were absent, and in 2018, the two main full-backs were absent. However, these are not the main reasons for being eliminated, because from beginning to end, the Brazilian team did not show the dominance that the champions should have. The midfielder who wore the No.10 jersey in the 14th World Cup was Oscar, the one who later joined the Super League. He was a typical diligent organizer at Chelsea, diligent? What is the difference between this and swearing? Let’s remember the name Oscar, the worst midfield organizer in Brazilian history. The striker arrow of the 18th World Cup is Jesus, the one who just retired due to injury. His retirement is definitely good for Brazil. He may be an excellent striker in other teams, but he can only be regarded as a loser in Brazil. Let us remember the name Jesus, the worst striker arrow in Brazilian history.

Brazil’s group match was 2 wins and 1 loss, and it didn’t sweep all the way, but why is Brazil considered the biggest favourite to win the championship? Because Brazil only played Serbia in the first game and South Korea in the fourth game, not only the top star Neymar was absent due to injury, but even other players left half their strength.

Playing Serbia, Brazil showed the ability to control the field, basically did not let Serbia have any strength to fight back, and finally defeated this potential dark horse in many people’s hearts 3-0; Facing South Korea in the first match of the knockout, it is an all-round display of offensive firepower. I can say responsibly that this Brazilian team is stronger than the champion team led by 3R in 2002. Brazil beat China 4-0, but now this Brazilian team only needs half time to beat South Korea 4-0. If it doesn’t take the initiative to stop, a bloody case may happen at any time.

How strong is this Brazilian team? So strong that they don’t need full-back assists anymore. As we all know, the Brazilian team has never lacked epic full-backs. At present, the main full-backs in Brazil are Danilo and Sandro, which are not the top players in the world and far from the ability of Carlos and Cafu. The substitutes behind them are Alves, who spent nearly forty years brushing data with soy sauce, and Telles, who went home because of injury. In recent decades, looking around the world, we have almost never seen such a "greedy" full-back. When Brazil played offensive football, these two full-backs never forgot their responsibilities as defenders, and they managed the defense wholeheartedly. Wang Shenchao and Wang Gang of the national football team were more active in attacking than Brazil.

Why do Brazilian full-backs seldom take part in the attack? Because of three words: no need. There are as many as nine strikers in Brazil this time. Except for Jesus and Richarlyson, the other seven have winger attributes, and even Richarlyson made his debut as a winger. The winger is almost the answer to the version of football in this era. Brazil has so many wingers and all of them are excellent. The last guy is Anthony, and Manchester United spent 100 million yuan to buy him. You said, why do you need a full-back assist?

In fact, Brazil has not won the championship for 20 years, largely because Brazil has been short of excellent attackers since Ronaldinho retired. I don’t know when Brazil’s most sought-after players in Europe are divided into three categories, the first category is goalkeepers, the second category is central defenders, and the third category is engineers’ midfielders who do dirty work. The homogenization of Brazil’s talents is similar to that of Spain and Germany, which can’t find a center, so they have been tossing the ball around in the middle and back court.

This phenomenon has a lot to do with the tactical changes brought about by the last 24-year World Cup in Brazil. During those 24 years, Brazilian attack experts emerged one after another, attacking beautifully and defending bean curd dregs. After learning from a painful experience, Brazil began to focus on cultivating defensive engineers and redefining tactical discipline.

Brazil won the championship in 1994 and in 2002, which are essentially the same. The first time was a big shovel with romario and Bei Beituo in front and dirty work behind it, and the last time was a big shovel with 3R in front and dirty work behind it. The reason why this match can be established is that the big shovel for doing dirty work in Brazil is different from that in other countries. The big shovel in other countries is a pure engineer, and all Brazilian players have excellent ball-throwing ability, ball control ability and organization ability. Brazil’s big shovel, which won the championship twice, is more capable of threading the needle than English epic midfielder Steven Gerrard, such as gilberto silva.

However, no matter how offensive and defensive the back is, it is absolutely impossible without the arrow of the front line. In recent ten years, except for Neymar, other attackers in Brazil are really bad. Until this World Cup cycle, Brazil finally ushered in a blowout of attacking talents. Today, the reserve of Brazilian attackers is second only to the quintet of Ronaldinho, Kaka, Robinho and Adriano in 2006. However, that Brazilian team was eliminated by France long ago. When it beat Ghana 3-0 in the first round of the knockout round, there was no whole, and the tactical content was extremely poor. Now the overall cohesion of the Brazilian team is extremely tight.

Of course, Brazil also has rivals in winning the World Cup. The strongest opponent this year is still France, which not only plays well, but also is the natural enemy of Brazil.

Since the 1980s, Brazil has been defeated by France in the World Cup, and fell to France in 1986, 1998 and 2006. The French team has a solid footwork, tight defense in the center and backcourt, and at the same time, there is no shortage of skills and attack experts at the foot, which really beats Brazil in style. However, due to the absence of Kantor and Bogba, the French team changed its attack route. Although Mbappé was in a state of explosion and Gleizman became an excellent organizer, Brazil really didn’t like this type of France, and the two sides were still 60% sure of playing Brazil.

Thankfully, after a lapse of 20 years, the World Cup has returned to Asia. As the only "football kingdom" in the world, Brazil has also seen the possibility of returning to the top. By the way, do you remember those names just now? Melo, Oscar and Jesus, if you are not an Arsenal fan this season, you may have forgotten these names again, because although these players once represented Brazil in the World Cup, they never shocked people from their achievements to their playing methods. Even if they wore Brazil’s bright yellow shirts, they would not leave too many memories in the hearts of fans.

Football fans support a team and want nothing more than two things: excellent results and beautiful games, which are exactly what Brazil must have at the same time when it wins the World Cup.

That’s why we can remember the gorgeous representatives of Brazil: Ronaldo with a lucky head, Ronaldinho who cheated the English goalkeeper Seaman, Roberto Carlos whose thigh circumference is thicker than anyone else, and of course, Brazil’s eukaryotic Neymar now;

That’s why, I will also remember those tough backbones of Brazil: Taffarel, who is not well known, Dunga, who is not handsome, and thiago silva, who is now an old and strong captain.

There is only one Brazilian team in the world, but Brazil has more than one kind of football content. In 2022, Brazil in Qatar may not present the world wave that Ronaldinho did at the beginning, but they will always have a wonderful volley side hook like Richarlyson, and at the same time defend their own goal with tough defense and tough confrontation.

So 20 years later, when the World Cup returns to Asia, we seem to see the excellent hope that the World Cup will return to Brazil. Especially when they pull out the banner of "Fight for Bailey", so that more people are willing to stand behind them. There is already a king in heaven, so let another one stay with us for a while on earth.

The World Cup needs Brazilian football, and the world needs Brazilian football more.

　　Zhongxin. com, Wuhan, November 2 (Wang Youzhe, Lin Xinyi, Fu Chengcheng) Recently, Hubei University of Economics launched a running App among freshmen to juniors. According to the regulations, students who have run for 30 times will pass. For each additional time, the effective score will be added with 3 points until 100 points. If the substitute runner is found, it will be treated as cheating and the file will be recorded.

　　Cui Gaoyuan, vice president of the School’s Sports school of economics and management, said that the scores of freshmen and sophomores using App for running and punching cards accounted for 30% of this semester’s sports scores, and juniors can only participate in the physical fitness test if their scores using App for running and punching cards reach the standard of passing or above. Students have at most one exercise record every day, which is related to sports achievements, and the excess part is only recorded but not related to achievements.

　　Cui Gaoyuan said that the purpose of linking the punch card score with the final sports score is to encourage students to get out of the dormitory, strengthen exercise, cultivate students’ healthy concept of loving sports and advocating sports, form good exercise habits and improve their physical fitness.

　　"I used to exercise very little. Since the school implemented the running APP, everyone is running and unconsciously wants to run two steps." Huang Ziwei, a freshman at the school, said that he insisted on punching cards every day and his running enthusiasm was much stronger than before.

　　It is worth noting that the school has also formulated an effective standard for single exercise. Boys should run for 1 km at a time, and the running pace should be within the range of 3-9min/km. If a girl’s running mileage reaches 0.8 km at a time and her running pace is within the range of 3-9min/km, her performance will be effective. Cui Gaoyuan said that the introduction of this regulation is mainly to ensure the safety of students, and secondly to achieve sports effects.

　　Huang Siqi, a sophomore in the school of finance, said that under this sports standard, you can complete punching as long as you walk faster. However, she also said that this punching APP has a task nature and may affect the quality of sports.

　　In this regard, Cui Plateau said that in the background, every time the APP is used to run and punch in, it is set to "random allocation", in order to reduce or even avoid the phenomenon of running on behalf of others. In addition, the school will also conduct supervision through inspection teams, student reports, and big data comparison analysis. If students are found to have "violation of discipline" such as running on behalf of others, once verified, they will be dealt with as cheating in the exam and recorded. (End)
