Can you customize your homework? Most of the "gunmen" who have become industrial chains are college students.

  With the countdown to the summer vacation, "writing homework" has become a hot "business opportunity" — — "A set of discounts except the number of words", "Write summer homework at a preferential price and also include postage" … … The reporter learned that from small advertisements to the Internet, from offline to online, "ghostwriting economy" has a long history, and now it has formed a complete industrial chain. Among the huge crowd who write homework, college students have become the absolute main force.

  Homework "feeding" becomes a summer vacation burden

  Who is writing it? The reporter learned that ghostwriting "gunmen" are generally college students and are called by ghostwriting platforms to form a team.

  A "gunman" who claimed to be surnamed Chen told reporters that he has been engaged in ghostwriting for two years, and the whole team has about 30 people. Not long ago, he also posted a job advertisement on the part-time online. There are students from mathematics departments, foreign languages departments and Chinese departments of various universities in the team, and some people have won prizes in national Olympic Mathematics and Physics competitions. "However, I rarely help students who are about to enter the third and third grades to write their homework, because they will enter the graduating class immediately and don’t want to miss their future." Xiao Chen said.

  Why is the homework writing business so hot?

  The reporter interviewed 60 primary and middle school students in Guangzhou Children’s Library, Guangzhou Book Center, Xinhua Bookstore and other places. Many students reported that there was not much homework in class, but the homework assigned by the school and parents was a bit breathless.

  Among the 60 primary and secondary school students interviewed, there are 40 primary school students and 20 junior high school students. Among the 40 primary school students, 30% think that they have more homework in summer vacation, and the remaining 70% think that the amount of homework is appropriate. In addition, the reporter also interviewed 10 parents, 4 of whom thought that their children had more homework and 6 thought that the amount of homework was not very large.

  Students don’t have much homework in class, but parents generally "feed" their children’s summer homework. During the interview, the parents of two junior students said that they had arranged one or two interest classes for their children, but they would not ask them to do more exercises. Nearly 80% of the senior students said that in addition to finishing their summer homework at school, they also volunteered or were asked by their parents to do more exercise books.

  Tian Guang, a professor at Shantou University and a sociologist, said: "Where there is demand, there will be a market. From the industrialization and continuous popularity of homework writing service, it is not difficult to see the current burden of students’ schoolwork." Tian Guang believes that we should reflect on how much homework is reasonable and necessary for students.

  Teacher Li, a math teacher in a primary school in Yuexiu District, admits that some homework is a mere formality. "Leave homework, children don’t want to do it; If you don’t stay, parents will worry that parents need to rely on the homework left by the teacher to restrain their children, and they will be relieved when they see their children writing homework. " He believes that students’ holiday homework should be divided into many types, such as assigning corresponding homework to children according to their different grades or evaluation grades. In this way, it can not only prevent students from looking for ghostwriting because of fear of difficulties, but also increase their autonomy in learning.

  Lawyer Cao of Guangdong Oriental Kunlun Law Firm pointed out that at present, the relevant supervision and legal constraints on ghostwriting industry in China are still in a blank state. The education department and relevant market supervision departments should take comprehensive measures to carry out comprehensive rectification, and at the same time increase publicity and guidance, so that ghostwriters, parents and students can form a correct understanding.

  Writing homework can also imitate handwriting

  "Contact customer service consultation — — Inform specific job types — — Determine the price — — Mailing homework — — Pay the required amount — — Start ghostwriting — — I will mail it to you after completion. " The reporter learned that almost every ghostwriting team has a complete set of operational procedures similar to the above. With the strong market demand, the price of "ghostwriting homework" has also been rising, from tens of yuan at the beginning to hundreds of yuan now.

  As a junior high school student, the reporter contacted the customer service of a writing team through QQ and asked to write a composition of not less than 500 words. The other party said that when pricing 50 yuan, 25 yuan should pay the deposit first, and then pay the final payment after writing, and the quantity is large and preferential. The next morning, the customer service sent the written composition to the reporter in the form of a document.

  The reporter then contacted a number of "gunmen" as a high school student. A "gunman" said that it is more difficult to do homework in summer vacation in senior high school. Math costs 2 yuan per page, and English costs 1.5 yuan per page. "Primary school and junior high school are relatively cheap. Primary school homework costs 1 yuan per page, and junior high school homework costs 1.5 yuan per page. If it’s a test paper assignment, it needs to be charged per copy, and the price per copy varies from 30 yuan to 70 yuan. ".

  In addition, it is more expensive to write Olympic math homework. Mimi, the "seller", told reporters: "Generally speaking, about 100 pages of science homework with answers is one by 100 yuan, one by 250 yuan without answers, and one by 800 yuan in case of Olympic Mathematics. However, the price can still be negotiated. "

  In addition to grade and subject difficulty, the time required to complete homework will also affect the quotation of ghostwriting service. The seller "U" said: "If the homework is required to be completed within 5 days and the time is tight, there will be more people to arrange, and there will be an urgent charge. Add 50 yuan in 4 days, 100 yuan in 3 days, 200 yuan in 2 days and 300 yuan in 1 day. If we can’t finish our homework on time, there is no charge. "

  The reporter’s investigation also found that the ghostwriting homework has been "upgraded" from simple answers to personal tailor. For example, as long as the students send their own handwriting to each other, the "gunman" can imitate the handwriting and write it. In addition, what kind of pen to use, whether to use correction fluid and correction tape, whether to draw circles, horizontal lines or mark in the process of solving homework, etc., all have "VIP service", and the charge is relatively expensive.

  Shenzhen children’s homework time ranks second in the country.

  data

  An educational platform has published a Report on the Stress of Homework in Primary and Secondary Schools in China, which shows the homework duration and related status quo of primary and secondary school students in China through a series of data. According to the report, in the past three years, although the length of children’s homework in China has decreased, it is still nearly three times that in the world.

  According to the report data, in the past three years, the learning pressure of primary and secondary school students in China has indeed improved slightly, and the average daily homework time has been reduced from 3.03 hours to 2.82 hours. Even so, the latest data in 2017 is still nearly three times the global level, or ranks first in the world. Judging from the cities surveyed, Shanghai ranks first in terms of daily writing time of 3.1 hours, followed by Shenzhen with 3.03 hours, and Beijing, Guangzhou and Tianjin rank third, fourth and fifth respectively.

New Drug Administration Law: Drugs imported without approval are not counterfeit drugs.

  Beijing Procuratorate Daily, August 26th (Reporter Xie Wenying) "164 votes in favor and 3 abstentions". On the morning of August 26th, the 12th meeting of the 13th the National People’s Congress Standing Committee (NPCSC) voted to pass the newly revised Drug Administration Law. The highlight of the revision is that the scope of counterfeit and inferior drugs has been revised, and drugs imported without approval have not been classified as counterfeit drugs. At the same time, respond to questions such as whether the network can sell prescription drugs.

  Because China has not implemented compulsory license, some cancer patients are still "illegally" buying foreign generic drugs to save themselves. The experience of Lu Yong, a leukemia patient in Dying to Survive, is a true portrayal of this situation. In order to alleviate the contradiction of "expensive medical treatment" among the people, and let the public use good drugs more quickly and afford good drugs, the State Council requires speeding up the examination and approval of new drugs listed overseas and strengthening the supply guarantee of drugs in short supply, which are all reflected in the newly revised Drug Administration Law.

  Yuan Jie, director of the Administrative Law Office of the Legal Affairs Committee of the National People’s Congress Standing Committee (NPCSC), said at today’s press conference that the import of drugs from abroad must be approved, which is a rule and principle made by law. Drugs that have not been approved, even those that have been legally listed abroad, cannot be imported. This time, the scope of counterfeit and inferior drugs was revised, and drugs imported without approval were no longer classified as counterfeit drugs, which was a response to the concerns of the people. The newly revised Drug Administration Law stipulates that if the circumstances are minor, the punishment may be reduced or exempted for importing a small amount of drugs legally listed abroad.

  "It is not the same as reducing the punishment to take drugs imported without approval out of counterfeit drugs and stipulate them separately." Yuan Jie said that the law has strictly set legal responsibilities, and the production, import and sale of counterfeit and inferior drugs without obtaining the drug approval documents are still punished according to the production, import and sale of counterfeit and inferior drugs.

  To implement the drug administration law well, the responsibility of the regulatory authorities should not be underestimated. Yuan Jie said that in the chapter on supervision and management, it is stipulated that if the drug supervision and administration department finds that a drug violation is suspected of committing a crime, it shall promptly transfer the case to the public security organ. The public security organ, the people’s procuratorate and the people’s court shall promptly transfer the case to the pharmaceutical supervisory and administrative department if there is no need to pursue criminal responsibility or be exempted from criminal punishment according to law, but administrative responsibility should be pursued.

  There is a high degree of social concern about whether prescription drugs can be sold online. In this regard, the newly revised Drug Administration Law also responded. Liu Pei, director of the Policy and Regulation Department of National Medical Products Administration, said that the current law clearly stipulates that prescription drugs cannot be sold directly to the public through the Internet, and the revised Drug Administration Law stipulates the principle of comparison in selling drugs through the Internet, that is, it requires the drug sales through the Internet to comply with the relevant provisions on drug management, and authorizes the drug supervision and administration department of the State Council to formulate specific measures in conjunction with the health authorities of the State Council and other departments, and stipulates that several types of specially managed drugs cannot be sold online.

  The newly revised drug administration law will come into effect on December 1 this year.

Li Song, an academician of China Academy of Engineering: Founding a solid shield of medicine dares to be a pioneer in science and technology.

  Not long ago, an online article about the flu burst into a circle of friends. Many people lamented: "A small flu is so harmful!"

  Although influenza virus has high variability, rapid spread and strong harm, this epidemic did not cause panic, because we have medicine in our hands — — From capsules and granules to injections, from the world’s first technology to the establishment of the world’s largest production line, China has become one of the countries with the richest anti-influenza drugs and the strongest clinical treatment support ability in the world. It has the independent prevention and control ability to deal with any scale of influenza, and has long since got rid of the dilemma that prevention and control drugs can’t be bought, can’t afford it and can’t be bought at a critical moment.

  When it comes to national emergency rescue and major epidemic prevention and control, we can’t help but mention a little-known research institute — — Overcoming various technical difficulties and achieving major scientific research achievements among the world’s advanced ranks, they can often win at such a critical moment — — This is a pharmaceutical research institute of the Military Medical Research Institute of the Academy of Military Sciences, which is known as "the vanguard of protection and the iron army of epidemic prevention".

  It is this institute that has successively graduated from seven academicians of the two academies, owned a "double-qualified" laboratory designated by an international organization and seven national and military key laboratories, won more than 190 high-level scientific and technological achievement awards represented by the national special prize for scientific and technological progress and the first and second prizes, obtained 74 new drug certificates and granted more than 500 patents, successively awarded an honorary title to a research laboratory, and five teams won the collective first and second prizes.

  In the spring of 2003, when the SARS virus was raging, the team led by Li Song, a researcher at the Institute, locked the epidemic virus as the main research direction and soon achieved results. They predicted that the next sudden major epidemic was likely to be influenza, and then they raised funds to carry out drug pre-research.

  "No one is forcing us to do these things. It is better to engage in other topics, send some articles, and evaluate the titles and ranks." Some young researchers in the team questioned. Li Song replied: "We are lucky to have the opportunity to do something truly meaningful for the country and the people!"

  By 2009, when H1N1 struck again, Li Song’s team once again created a miracle: the drug production capacity was increased by 30 times, and the national reserve task of 26 million people was completed in only 135 days, saving the country 5.7 billion yuan in procurement funds.

  Can achieve such results, relying on a "cold bench" spirit. In the field of anti-drug struggle, Li Jin, a researcher at the institute, has been sitting on the "cold bench" for 20 years. Work normally ends at 10: 30 at night, and the progress of scientific research is reported regularly. All major discoveries must be verified repeatedly … … These unwritten rules have been adhered to in Li Jin’s research group for 20 years. This is an ordinary 20 years, except for the laboratory or the laboratory; This has been a hard journey for 20 years, and every progress has been difficult.

  Hard work pays off, and good news keeps coming: Li Jin was hired as the chief scientist of the first national 973 project in the field of drug rehabilitation in China; His research group discovered a new opioid function regulation system and proved for the first time that this system has a clear inhibitory effect on opioid addiction and relapse; A new Chinese medicine for preventing opioid relapse — — Duanjin Jiedu Capsule has ideal detoxification and relapse prevention effects, and it is not addictive. Recently, it has obtained the national clinical approval & HELIP; …

  In the pharmaceutical synthesis laboratory, the reporter saw such a scene: on the computer screen, a mass of green substance appeared, with a yellow depression in the middle, and a row of irregular branches slowly approached and embedded in it.

  "This is a virtual drug screening experiment conducted by researchers using trillions of cluster computer systems." Xiao Junhai, deputy director of the institute, said that this platform can screen 500,000 molecules every day, which is thousands of times more efficient than traditional screening methods. The workload in the past six months can now be completed in a few days. He introduced that a good platform for production, learning and research is a big "magnetic field" for them to attract talents.

  "In addition to yearning for military status, I value the scientific research environment here, the innovative atmosphere that is not troubled by fame and fortune, and I am willing to work here without paying money!" Duan Xiaotao, a doctor studying in the United States, would rather give up his high salary than come to the institute for scientific research.

  At present, the institute has three academicians of the two academies, 30 of whom have been selected into the national major talent projects such as the 100-million-person talent project and the national 10,000-person plan, and 15 of them have won the military outstanding talent award or been selected into the military major talent projects such as the innovative talent project.

  What is rare is that such a team that chooses the best among the best has a heart that is willing to contribute and indifferent to fame and fortune. As we all know, drug research and development and production are extremely profitable in the market, and patent fees alone are very considerable. However, when a new type of antibiotic came on the market, the experts of the institute strongly urged enterprises not to mass-produce for economic benefits, so as not to lose the last line of defense against superbugs. Li Song has a "three noes" principle — — Do not love power, fame or wealth.

  In times of crisis, they dare to rush ahead. After the "8.12" explosion accident in Tianjin Port in 2015, Wang Yongan, a protection expert of the Institute, took the lead in entering the explosion core area and completed a "most beautiful retrograde". Wearing heavy protective clothing and working continuously in high temperature, he almost collapsed. After careful investigation, he put forward "don’t enter unless you prevent it, don’t enter unless you train it, handle it across regions, and protect it at different levels", which became the action criterion to guide the rescue.

  Wang Yongan’s feat in such a critical moment is not uncommon in this institute. One year, the institute undertook the production task of an emergency drug. Due to the dangerous production process, the manufacturer suddenly changed his mind and withdrew all the workers on the eve of construction. Under urgent circumstances, Jiao Kefang, Xie Yunde and others stationed in pharmaceutical factories resolutely undertook all production tasks. Put buckets of raw materials into the reaction kettle by hand and take turns to be on duty 24 hours a day … … After more than 40 days, they delivered the qualified drugs to the troops on time.

  "There are many touching stories behind every scientific research achievement." Director Su Ruibin was deeply touched.

  Behind the story is the continuous struggle and selfless dedication of generations of researchers in the institute.

9.6 points "adult animation", with scale and depth.

Text | Ten o’clock movie original


You won’t believe it.

Spongebob, which seems young, is actually an adult animation. 

Here, the crab boss will also encounter a midlife crisis.


For the purpose of protecting children, Nick Children’s Channel has removed the episode and other sensitive content. 


However, after revisiting this animated work many times, Lao Mei Er found that its audience is not just children.


The underwater group portrait that people talk about is completely a movie.
Illustration of contemporary young people’s survival.


Won the 374th outstanding employee of the month, and then what? 


Spongebob’s name was a misunderstanding from the beginning.

He is actually a post-80s migrant worker named Bob, whose daily job is to be a senior chef in krusty krab restaurant.


 

This title sounds great, but it’s actually nothing.


Because, the crab boss always excuses to delay the salary, and the salary is always lower than the legal minimum. 


As a colleague of Spongebob, Squidward Tentacles has already seen through everything, and he just does his job inefficiently every day. 


But Spongebob is not, always rushing to the forefront like chicken blood, insisting on fighting for the cause that you love for life.


You know, capitalists love this kind of dreamer who is indifferent to fame and fortune. 

Crab boss bought a pair of leather boots for his daughter Pearl Krabs, but he didn’t want to smash them in his hand … It’s easy. 


He turned his head and made up a gimmick that "only the best hamburger chefs in the world are allowed to wear it" to cheat Spongebob out of his salary. 


As a boss, the skill of drawing cakes is not limited to this.He also named Spongebob as the outstanding employee of the month for 374 consecutive years.


As the backbone of several honors, Spongebob is naturally the best choice for the branch manager. 


So, he sat neatly under the stage, his eyes shining, and he was even ready to give a thank-you speech, just waiting for the crab boss to read his name. 


But in the end, it was Squidward Tentacles who got the promotion. 

Why? 


Crab boss said, because Squidward Tentacles is more mature.


On the endless bikini beach, Spongebob’s energetic appearance is a bit out of place. 


So, when Squidward Tentacles accidentally accused him of being a freak, Spongebob decided to be a normal person. 


After trying again and again, he gradually lost his pores, freckles and edges, and replaced them with smooth and smooth.


He wants to change back. 

Spongebob shouldn’t be a nondescript product on the boring life assembly line. 


In order to help him regain himself, he sent a big star to accompany him to do all kinds of unique behaviors. 


When they accidentally fell into the water, the passing fish saw this scene and asked curiously, "Mom, what animal is that?" 


Little fish mother answered:"Those are rubbish, baby, they are not normal people." 

Philosopher: Genius sends big stars? Idiot Patrick? 

When it comes to Patrick, people will think of his friendship with Spongebob for the first time.

You all know the story of catching jellyfish, right? 


Da Xing invited Spongebob to catch jellyfish, but Spongebob refused on the grounds of going to school. 


Spongebob asked, "What do you do when I’m not at home?" 


Patrick replied, "When you come back."



Once, Spongebob and the rascal traveled to the future in a time machine. 


Bikini beach has already turned into a long yellow sand after the famine in Crab Castle.


All the sea creatures are gone.


Only Patrick suddenly poked his head out and told Spongebob in surprise:


"They all gave up on you, but I didn’t, because I’m not very smart."



Pai Daxing is clumsy and often goes wrong, but in an experience of gaining wisdom coral brain, his IQ soared rapidly and he refused to catch jellyfish with Spongebob.


He was not happy after he successfully entered the field of science. 


In order to get back Spongebob, Patrick decided to switch back to his brain and said, "Knowledge can’t replace friendship. I’d rather be an idiot than lose you."



But is Patrick really an idiot? 


When Spongebob is frustrated by his friend’s snobbery, he will make a pertinent statement: "When it comes to money, no one is right or wrong. The key point is whether there is friendship or morality."


He will suddenly go to the restaurant next door to his house for a night, just because "sometimes I want to run away from everything." 


When Squidward Tentacles asked him why he had to bring two boxes of stones to stay in the hotel, he responded confidently: "How do I live is none of your business!" 



He even saw through the social reality: "Life is unfair, get used to it!" "

 
Pai Daxing is a man who is as wise as a fool, and his philosophy of life, which he inadvertently reveals, often leads to a solution for those who are fascinated by the authorities. 


However, detached from things, he will inevitably encounter lonely moments. 


When he saw Spongebob leading Gary the Snail to a pet competition, Patrick suddenly lost control and roared:


"You don’t understand! Spongebob, you never know how lonely it is to be alone behind the blockade … " 



As a migrant worker, Squidward Tentacles is the opposite of Spongebob.


He works as a cashier in krusty krab restaurant just to survive, and he is not as obsessed with the ideal of becoming the strongest hamburger chef as Spongebob. 


Spongebob always has no feelings, but Squidward Tentacles can see through the nature of capitalists. 


What should we do?


Uprising: breaking the window of the slave kingdom of the crab boss!

Standing on the bikini beach, he loudly complained about the bad behavior of the crab boss, which attracted the support of the passing underwater creatures. 


But, listen to what they are saying- 

Fish A: "I’m hungry after supporting him for a long time." 

Fish B: "Hey, let’s go to krusty krab now." 

Set the underwater creatures, trampling on Squidward Tentacles’s body, and heading for the restaurant. 


Squidward Tentacles lying on the ground was completely doused with enthusiasm, and then murmured:


"No one really cares about the fate of employees. All they really care about is their own happiness."



The cashier’s work day after day kept killing his fighting spirit.


But passion will come back one day: "If one day I really realize my dream, I will never let my feet stand on this greasy floor!" " 


The job is boring and has no future, and the boss is very stingy. 


Therefore, Squidward Tentacles resigned indignantly after being misunderstood by the crab boss that he was an inside job thief, and firmly believed that there was much to be done in the future. 


But in the next scene, he is begging on the roadside in rags, and sees the reality clearly in his life of hitting the wall several times: "I am a loser!" "



Without the means to make a living, homeless. 


Even the dream about artists that has always fascinated him has been ruthlessly killed by life. 


Crab boss had accidentally bumped into Squidward Tentacles in the cemetery. 


When he approached, he found that there was only one sentence on the tombstone:Buried here are Squidward Tentacles’s hopes and dreams.


Alien: There is a Texas squirrel at the bottom of the sea. 

In the vast underwater world, there lives a squirrel from Texas, Sandy.


She is not only good at catching jellyfish like Spongebob and Patrick.


But as a scientist, explorer and inventor, he is good at karate, weightlifting and rodeo, and often wins the first prize in various competitions. 


She’s not like Squidward Tentacles, who is both bereaved and fearful.


Instead, I live a positive life and successfully broaden my circle of friends with excellent social skills.



Sandy is more powerful than all marine animals, but she is the only land creature that appears at the bottom of the sea. 


The alien spacesuit and helmet are destined to make her an underwater alien. 


Once, marine creatures gathered together and laughed at her for not being able to survive here without external assistance. 


After hearing this, she flew into a rage and immediately tore the spacesuit and broke her helmet, trying to blow the arrogance of the other side.



But being as good as Sandy can’t change the physical differences and the geographical disparity. 

She is a Texas squirrel wandering on bikini beach, wandering at the bottom of the sea.


Sandy, who is homesick, occasionally hears a sentence that has nothing to do with her and will instantly break through the defense:


"Fly, little jellyfish, fly back to your own home. You don’t belong to this deep seabed. Go find your friends and family. I know you all miss each other deeply."

Maybe it’s time to leave. Sandy dried her tears and said, "It’s time for the wanderer to go home."

coda

This animated work has been released for thirteen seasons in succession.

The seasonal douban score is 9.4+, and the highest score is 9.6.


Even in the off-duty days, people often dig out the details. 


However, this realistic story is still underestimated. 


Because- 


It is not serious, and it often completes the process of self-mockery and introspection in an easy way. 

It doesn’t preach, but it can’t wait to pierce the window paper that stands in front of the truth of life. 


It found us in adjacent dilemmas.

Guide to psychiatric emergency treatment

Original Wu Fei Chat 686

The public is relatively familiar with the emergency department of general hospitals. For sudden physical diseases such as high fever, hemiplegia, coma and trauma, the emergency department of general hospitals is the first choice for treatment. So, what’s the difference between the emergency department in psychiatric department and the emergency department in general hospital? Under what circumstances should psychiatric emergency treatment be the first choice?

Next, I will take you into the psychiatric emergency room to show the real daily psychiatric emergency treatment.

Scene one

In front of the psychiatric emergency department, the 120 ambulance and the police car stopped in tandem, and a young man’s hands and feet on the 120 flat car were fixed by clothes and soft cloth belts. The boy shouted loudly, the content was messy, the speech speed was fast, and he wanted to break away from the constraints and was restless. Around 3-5 family members followed closely, and 120 staff and police escorted together. The scene was a little urgent, chaotic and crowded.

Scene 2

Young female college students came to the clinic accompanied by counselors. After entering the clinic, they asked the counselors to avoid it and whispered that they were under great academic pressure. It happened that they broke up with their boyfriends recently, which was very painful. They felt that life was hopeless and had suicidal thoughts. By cutting yourself, you will feel comfortable and relaxed when you see bleeding. Then you will take off the sunscreen cuff, and your arm will be exposed with shocking red wounds and rows of gray scars that have been cut with a small knife.

Scene 3

In the morning, a middle-aged woman came to the clinic, complaining of sudden palpitation, chest tightness and high blood pressure in recent months. I went to a general hospital for a cardiac examination, and no problems were found. The doctor suggested that I go to the psychiatric department and the patient is considering it. I woke up suddenly after falling asleep tonight, with a severe sense of suffocation, dying, flustered and sweating, and I was very scared. I felt that I couldn’t last tonight.

Scene 4

A mother and son were sent from 120 outside the hospital. The anxious young mother took the boy and called the doctor to see her before she entered the clinic. The patient has been seeing a doctor regularly in the children’s psychiatric clinic for the last two months. Yesterday, an antipsychotic drug was added to the clinic, and each patient took it once yesterday and today. At five o’clock this afternoon, my eyes turned upside down, my eyelids couldn’t be closed, I always looked up, my body tightened, my neck was stiff, my head tilted to one side, and I even walked sideways. It looked particularly uncomfortable. Mom anxiously asked the doctor what was going on.

Under what circumstances should I come to the psychiatric emergency department?

Emergency psychiatry is a branch of clinical psychiatry, and it is also a branch of emergency medicine. Medical staff mainly take emergency medical care measures for patients with mental disorders when they suddenly get sick or their condition suddenly worsens, endangering their own or others’ safety, and serious adverse drug reactions.

Let’s sum up the situation that needs to come to the psychiatric emergency department:

● Psychiatric emergency

Including excitement, injury and destruction, self-injury and suicide, serious hallucinations and delusions, numbness, refusal to eat and water, panic attacks and so on. Among them, excitement, self-injury and suicide are the most common reasons for psychiatric emergency treatment.

Specific performance includes:

Have impulsive tendencies, physical violence, verbal threats, or other risks that endanger the safety of others;

◆ Self-injury behaviors, such as cutting wrists and hitting walls; Or have a tendency to commit suicide, revealing suicidal thoughts to people around them, preparing suicide plans, or committing suicide such as overdose and jumping off a building (when serious physical problems have been caused, even life-threatening ones, you need to go to a general hospital first), such as scenario 2;

◆ Symptom of hallucination and delusion does not belong to psychiatric emergency, but if the content of hallucination and delusion may stimulate the above behaviors, it belongs to emergency category;

◆ Stunned, refusing food and water, or acute mental disorder, sudden nonsense, weird behavior, etc., such as scene 1;

◆ Acute anxiety attack, feeling of dying, flustered and breathless, panic, etc., as shown in Scene 3.

● Serious adverse reactions of psychotropic drugs.

Such as acute dystonia, malignant syndrome and 5-HT syndrome.

Acute dystonia is a kind of extrapyramidal syndrome, which is more than the early stage of taking antipsychotics, and often appears within 48 hours after the first medication. It can be manifested as upturned eyeball, torticollis, difficulty in opening mouth, choking with drinking water, and inverted horn arch. In severe cases, laryngeal muscle tension disorder occurs, which leads to upper respiratory tract obstruction, dyspnea and even life-threatening. This is the case in the fourth scene above.

Malignant syndrome (NMS) is a rare and life-threatening serious adverse drug reaction, which is mostly caused by taking a large number of antipsychotic drugs in combination. It is characterized by high fever, muscle tension, change of consciousness and autonomic nervous dysfunction. NMS may be complicated with rhabdomyolysis, arrhythmia and respiratory failure.

5-HT syndrome is also a potentially fatal syndrome, which usually occurs at the beginning of the use of 5-HT drugs or excessive use, and is rare at therapeutic doses. It is characterized by disturbance of consciousness, tremor, diarrhea, hyperreflexia, myoclonia and high fever.

Some of the above patients can be properly treated in psychiatric emergency. If there are serious comorbidities or life-threatening situations, they need to go to the general hospital for emergency treatment to stabilize their physical condition.

● Psychiatric drug overdose or poisoning

Such as lithium poisoning, antipsychotic poisoning and benzodiazepine poisoning. Note that people who have been poisoned by psychotropic drugs and have potentially life-threatening clinical conditions need to go to a general hospital for treatment first. Poisoning by other substances, such as pesticides, cleaning agents, pesticides, carbon monoxide, etc., should be treated in general hospitals first.

Lithium poisoning usually occurs in people who take lithium for a long time or by mistake. The therapeutic dose of lithium salt is similar to that of poisoning, so it is necessary to monitor the blood lithium concentration when using it. Mild lithium poisoning may cause dizziness, nausea, vomiting and diarrhea, and severe cases may cause limb tremor, nystagmus, ataxia, slurred speech, convulsion and coma.

The symptoms of antipsychotic drug poisoning are atypical, such as hypothermia or hyperthermia, blood pressure drop and even shock, coma, arrhythmia, abnormal electrocardiogram, seizures and so on.

People poisoned by benzodiazepines have a history of overdose or misuse of benzodiazepines, which are manifested as disturbance of consciousness, lethargy, coma, respiratory depression, bradycardia, decreased blood pressure, dizziness and ataxia.

● Mental disorders and acute withdrawal reactions caused by psychoactive substances such as alcohol, opioids, marijuana and central nervous system stimulants.

Alcohol is a psychoactive substance that is easy to obtain in China, so it is common for emergency patients to drink too much and have acute alcohol withdrawal.

Alcoholism is easy to identify. Patients who ingest a large amount of alcohol or alcoholic beverages will suffer from disturbance of consciousness, lethargy, coma, behavioral disorder, obvious ataxia, nystagmus, arrhythmia and shock within a short time.

Alcohol withdrawal refers to a series of symptoms caused by long-term heavy drinkers who suddenly stop drinking or reduce their drinking. There may be sweating, shaking hands, shortness of breath, tachycardia, elevated blood pressure, anxiety and insomnia, and in severe cases, hallucinations, seizures, tremors, delirium, etc., and even life-threatening.

It should be emphasized that when the vital signs of the above patients are basically stable, they can go to the psychiatric emergency department for treatment; If the vital signs are unstable, you should first go to the emergency department of a general hospital to stabilize the vital signs, and at the same time ask the psychiatric department for consultation, or refer to the psychiatric department for emergency treatment after the vital signs are stable.

● Individuals who have recently suffered mental and psychological trauma and suffered obvious social function damage.

Individuals are in an extremely painful and disoriented situation, which seriously affects social functions. For various reasons, when they are temporarily unable to go to the outpatient clinic, they can go to the emergency department for temporary treatment to help patients maintain a stable state before receiving outpatient treatment.

Under what circumstances don’t come to the psychiatric emergency?

● The patient did not come, and relatives and friends came to consult on behalf of the patient;

● Patients who regularly inject long-acting antipsychotics come for long-acting injections;

● Patients who can’t hang the outpatient number or find it difficult to register;

● Patients who need to issue various proof materials such as disease diagnosis;

● Minor patients (younger than 18 years old) must be accompanied by legal guardians;

● Patients with mental disorders who have caused physical injury due to self-injury or suicide, are in life-threatening situations, or are accompanied by consciousness disorder, serious physical illness, high fever, etc., need to go to a general hospital first.

Before reaching the psychiatric emergency department

How do family members cope with patients’ acute condition?

one

When there is an acute attack of mental illness and the patient is at risk of self-injury or injury, the family members should keep calm, find ways to protect the patient, prevent themselves and others from being injured, and send them to the hospital in time. If necessary, actively seek the help of other family and friends or emergency personnel, police, etc.

2

Calm patients’ emotions and avoid quarreling and direct eye contact. If there are sharp instruments beside the patient, try to take them away. If the patient has a sharp instrument in his hand to hurt others, stay away from him and ask the police for help as soon as possible.

three

When patients with mental illness have hallucinations and delusions, avoid arguing with patients about the authenticity of symptoms and seek professional guidance in time.

four

For those who have suicidal thoughts or attempts, or even have committed suicide by self-injury, their families should bring the patients to the hospital as soon as possible. For those who cannot be hospitalized immediately, their families should monitor them 24 hours a day, take care of the drugs and dangerous goods at home, or call the psychological rescue hotline.

five

For the early use of psychotropic drugs, during the period of increasing drug dosage or multi-drug combination, family members need to know the possible adverse drug reactions in advance, and slowly increase or decrease the dosage according to the doctor’s advice to avoid sudden increase or decrease of drugs. When the patient has the serious adverse reactions mentioned above, he should go to the emergency room in time.

six

If there is an overdose, the family members need to quickly identify and respond. When the patient is not sure about the drugs to take, collect the drugs that may be used around the patient, carry the information about drug use and empty medicine boxes, and seek medical advice in time.

seven

Patients with acute withdrawal reactions need to seek medical attention immediately, especially those with alcohol dependence. Wrong withdrawal may lead to serious withdrawal reactions and irreversible brain damage, and even life-threatening, requiring hospitalization or complete withdrawal under the guidance of a doctor.

In most cases, emergency patients have two places to go, hospitalization or outpatient treatment. For patients who can be referred to outpatient treatment, emergency doctors will help to deal with the current emergency, reduce excitement, reduce impulse risk, carry out suicide intervention, etc., to ensure that patients are in a relatively stable state before outpatient doctors receive treatment. For patients who need hospitalization, after receiving temporary emergency treatment, they are waiting for hospitalization according to the emergency hospitalization process.

In psychiatric emergency, ensuring safety is the most important thing, including patients’ physical safety and mental behavior safety, helping patients sort out and solve the most urgent and serious clinical conditions, and winning time and laying a foundation for receiving the next treatment.

Forbidden kingdom: A good movie without watching Kung Fu.

First of all, CNN is an idiot. They commented that "forbidden kingdom" is extremely wonderful in martial arts, but the story is extremely stupid. It’s really a foolish thing to think about Huashan’s sword after learning kung fu for a few days. Associated with the recent condescending, malicious and shameless attacks on China, it makes people feel that this arrogant arrogance is rooted in extreme ignorance and self-righteousness towards the East. In the eyes of China martial arts fans who have been influenced by kung fu movies for decades, the martial arts of this film are as normal as most insiders predicted, and it is really commendable. However, the content of the film is full of new ideas, and all kinds of beauty can be understood by shameless boys such as CNN?


The main line of the film is about a child who ventured into a world made up by himself. Actually, it is not a very new theme. The earliest classic can be traced back to The Wizard of Oz, and this film does not hide the meaning of paying tribute to this classic. Jason enters a dream, and he pushes open the door to see the beautiful and magnificent scene. The lens is consistent with the design of Tao Le reaching the fairyland and pushing open the door to see the mysterious scene in The Wizard of Oz. The most recent work of this kind is Kung Fu by Stephen Chow. In fact, forbidden kingdom is quite close to Kung Fu. For the sake that the screenwriter said that he had not seen Kung Fu, I can assume that great minds think alike. Of course, the story of "forbidden kingdom" is much more straightforward than that of "Kung Fu", but there are still many wonderful designs and hints in the film, such as why Jackie Chan’s role is called "Lu Yan", because the old Jackie Chan’s shop is "Lu Yan Pawnshop", and when he meets Liu Yifei in Boston at the end, it can be understood that Liu Yifei is a girl who Jason secretly loves in his life and has been programmed into his dreams, which is the experience that most boys have had (this is the same as "Kung Fu") In the dream, Lu Yan was shot by an arrow, and Jason went to the home of the God of War alone to change the elixir. In fact, it was a projection of his remorse that killed Old Jackie Chan because of his cowardice.

In fact, all kinds of characters and story elements in the film come from China martial arts and kung fu films that he is obsessed with at ordinary times, such as the white-haired witch from bride with white hair, golden swallow from come drink with me, silent monk from Shaolin Temple, the drunken fairy from Drunk Boxing, Wuzhishan and magic generals in The Journey to the West, Shaolin Temple and the legendary Shaolin thirteen stick monks. I don’t know anything about these China movies and cultures, and I lost my childlike innocence early. I don’t understand the mood of a kung fu fan boy at all, insisting that the story of forbidden kingdom is ridiculous, but I don’t know that it is himself who is ridiculous. Of course, the adventure story of "forbidden kingdom" doesn’t have much creativity, but don’t forget that this is a little boy who has watched countless China martial arts films in which good and evil are separated to be a little naive. The world he imagined, the world of children is simple, and it would be really ridiculous if he was involved in something profound and complicated. The only thing I don’t like very much is the ending. Jason, who came back from the dreamland, suddenly had kung fu, beating the shit out of several hooligans. I think it’s quite artificial, and it also makes the movie divorced from the truth. If Jason got courage from kung fu and adventure instead of kung fu, I think the movie would be much better.




The artistic design of the film opened my eyes. The legendary Wuzhishan was made with magic and realism by special effects. The evil palace of the God of War in Yujiang was built on the mountain, and the inspiration was obviously from the Hanging Temple in Datong, China. Jason and his party headed for the territory of the God of War in Yujiang. Just like The Journey to the West and the heroic journey in The Lord of the Rings, the God of War in Yujiang finally wanted to destroy the golden cudgel in the fierce inflammation, which was inspired by the setting of destroying the Lord of the Rings in Mount Doom in The Lord of the Rings. The costumes of several main characters in the film are very wonderful, and the most amazing thing for the audience is undoubtedly Li Bingbing’s white-haired witch. It’s really white-haired and snowy, dancing in the air, and the color matching of the whole body is excellent. The makeup on the face also highlights the character Leng Yan and there is no lack of rare temperament, which is more successful than the Brigitte Lin version of the white-haired witch. Two of my favorite scenes, one is Jason practicing martial arts between waterfalls, and Jet Li explains that the essence of China Kung Fu is to let nature take its course, just like a piece of water. There is also the design of the hotel, which shows that it has been well researched. The drinkers sit on the floor at will, accompanied by singers and dancers, and are full of charm of the Tang Dynasty.

As for the film’s martial arts, the movements directed by Yuan Heping are of course standard, but they have completely lost their peak, and it’s hard to see a stroke of genius, but more of a repetition of the past. Although the film’s martial arts is also a tribute to the summary of various old China martial arts films, Jackie Chan’s drunken fist and snake-shaped tricky hand appeared, and Jet Li’s mantis fist and stick technique, but martial arts can be the same, and the movements should still be innovative. Of course, this probably has something to do with Yuan Heping’s lack of final editing rights, which once again shows that western filmmakers don’t know how much they have to do for a living, and they occupy that.

In my opinion, although this film will make many Chinese people laugh, in fact, the yearning and respect for China culture is sincere at heart, and it is also a film that introduces China culture (although it is popular and superficial) to the world. I believe more and more westerners will know that the real source of China culture is China, not Japan. The screenwriter of the film loves China philosophy and culture and is still practicing mantis boxing and Chen Taiji since he said it. Foreigners are still so, but if we China people abandon our own culture, can we not be ashamed?

Analysis of Tank 300 Hybrid: The reliability of single motor is good, but how to optimize the fuel consumption of feed?

The combination of hybrid and off-road vehicles often makes off-road enthusiasts full of expectations, with low fuel consumption and high power.
At the just-concluded Chengdu Auto Show, the tank booth brought two hybrid models, the tank 300 HEV and the tank 500 PHEV. Although both cars were just unveiled, they also attracted the attention of a group of potential consumers. The combination of hybrid off-road vehicles is not new. herdsman 4xe plug-in hybrid vehicles have been launched for a long time. Although the strength is still very strong, the price is also very expensive.

Therefore, consumers still need a hybrid off-road with a lower price. Of the two cars released by the tank, the attention of the tank 300 HEV should be the higher of the two. What is the strength of the HEV system used in this tank? What are the advantages and disadvantages of putting it on the tank 300?
Why not use DHT and P2 structure?

The pure fuel vehicle market is welcoming a new era, not pure electricity, but hybrid. This is also the reason why so many car companies have started to launch hybrid products one after another. According to the previous exposure information, the 300 HEV version of the tank will use a 2.0T hybrid system matching P2 motor, using a 9HAT gearbox, with a maximum power of 224kW and a maximum torque of 640 Nm.

P2 motor structure has three layout modes:

1. Put the P2 motor on one side of the engine, and the clutch is in front of the motor and the transmission. Under this structure, the main function of the P2 motor is similar to that of the P1 motor, which can play the role of parking power generation and starting the engine;

2. Secondly, the P2 motor is placed near the gearbox, and the clutch is between the P2 motor and the engine. The P2 motor can be directly placed on the input shaft of the transmission, or it can be linked with the input shaft of the transmission through gear transmission. At this time, the P2 motor can drive the vehicle independently and realize energy recovery and power generation.

3. Thirdly, the P2 motor is placed between the engine and the transmission, and two clutches are added, so that the motor can drive the vehicle independently and start the engine.

The layout of the third structure makes it work more comprehensively and maximize the utilization rate. The working principle is that after starting the vehicle, the battery pack high-voltage system is ready to work. At the same time, the battery will supply power to the P2 motor, one of which is coupled, and the P2 motor will output power to the transmission, and finally drive the vehicle.

During driving, if more torque is needed or overtaking is required, the clutch with the engine will also be coupled, so that the engine and P2 motor form a series output mode, and the battery will also output electricity to provide energy for P2 motor.

When going downhill or braking, the clutch between the engine and the P2 motor is decoupled, and the wheels drive the P2 motor to reverse and charge the battery.

What are the advantages and disadvantages of using P2 structure?

Some people may be curious, why didn’t the DHT hybrid system with lemon platform under the Great Wall appear on the tank 300 HEV? Moreover, lemon DHT is a dual-motor system, and theoretically the mixing effect will be better than the known P2 structure. Let’s understand it this way. The lemon DHT hybrid is suitable for the models under the lemon platform, but it is not compatible with the models on the tank platform.

Therefore, structurally, the two are unlikely to appear at the same time; However, the tank wants to have a hybrid product, so it is easy to understand if the P2 structure is selected. One of the advantages of P2 structure is that it can improve the power performance and fuel economy with the minimum cost.

Compared with the motor structures of P0 and P1, the compatibility of P2 motor structure has been greatly improved. The structure of P2 motor is located between the gearbox and the engine, so it is not necessary to arrange it in the engine housing like P1 motor, so the layout form can be more flexible.

From the point of view of manufacturing new cars, P2 structure has the advantages of small transformation range, low cost and strong compatibility. So what are the disadvantages of this P2 structure?

P2 motor only stops driving the vehicle when the gearbox is switched to neutral, and then starts the engine. Because P2 structure is a single motor, it is difficult to give consideration to both power generation efficiency and power output at the same time, so one motor has to take care of both ends, which often leads to P2 structure not being able to achieve full coverage of various scenes.

At present, the systems used by other domestic brands, including DHT of Great Wall, are all dual motors, one for generating electricity and one for driving, which are the mainstream configurations.

It’s not helpful for off-road, and it’s friendly to fuel consumption.

The common application scenario of P2 structure is that it is applied to the weak mixing system and adopts the parallel arrangement of belts or gears, which can be compatible with the existing gearbox design, and is usually applied to the 48V weak mixing system by European brands, just like the first layout scheme mentioned above; The tank 300 HEV uses a set of 2.0T engine +1.7 kWh battery.

Can the tank 300 HEV you think of improve the off-road ability a lot?

The answer is no, don’t forget that most of our hybrid cars and plug-ins, fuel saving is the most important goal. For hard-core off-road SUVs, it is necessary to add a premise, that is, "guarantee off-road ability and reliability". Therefore, the ultimate goal of P2 hybrid for tank 300 HEV is to "optimize fuel consumption".

P2 motor can drive the vehicle independently. When going downhill and braking, the kinetic energy recovery system can also cut off the connection with the engine (decoupled from the engine), and it will move with the crankshaft like P0 and P1, thus losing kinetic energy. Because there is a transmission ratio with the output shaft, too much torque is not needed, and the size of the motor is not large, so that the performance of fuel economy can be better reflected while reducing the cost and weight.

If you really want to improve the off-road limit, you can use the dual-motor scheme of herdsman 4xe to generate electricity and drive the vehicle. In order to ensure the reliability, the driving mode can be automatically matched without intelligent real-time monitoring of the throttle opening and closing angle, but a pile of ECU and wiring harness can be saved to improve the reliability.

Perhaps for one reason, the tank 300 HEV was not allowed to do so. First, from the perspective of cost, the structural transformation of two motors and the cost of parts will rise. For this kind of thing, 500 PHEV tank is more suitable.

Finally, maybe in the product announcement stage, the hybrid system with P2 structure will be described emphatically, which can make the fuel consumption very low. After all, there is a large battery to support pure electric driving. Then, after feeding, the system structure of single motor may make the fuel consumption performance not as good as advertised, and other domestic brands have had similar situations in this regard.

The only difficulty that falls on the tank 300 HEV is to solve the disadvantage that the single motor inherent in the P2 structure cannot cover various working conditions.
