How to break "hot search anxiety"? Netcom Office issued a document to stop malicious marketing.


Special feature of 1905 film network Have you ever had such an experience in the process of catching up with film and television works — — Open the social software, the characters in the play seem to live on the hot search list for 24 hours, and every move of each character can come up with a topic that attracts countless discussions; Brush a short video, one group of people is breaking through the defense in the cinema because of this detail, and another group of people is beginning to think about a certain bridge in the play … …


One-pass operation is as fierce as a tiger, and these bombing marketing makes many works naturally become the "explosion" of the opening year/season in the eyes of netizens. However, under the tropic of cancer, many of these so-called "hot" film and television works "have no such drama" among the audience.


Why is there such a puzzling "contrast" Not long ago, People’s Daily and Guangming Daily successively issued articles criticizing the excessive pursuit of flow effect in the marketing of some film and television works, and the publicity stunt runs counter to the quality of content, even destroying the film and television industry environment in which the audience objectively and rationally perceives art, and causing serious damage to literary and artistic creation.



# Over-marketing can’t win the hearts of the audience # The topic immediately went to the top of the hot search list, and commented at the bottom of the article. Many "long-cherished" viewers left messages denouncing the influence of over-marketing on the feeling of chasing dramas, and many even directly pointed out the works and stars suspected of "over-marketing" in their eyes.



It is true that the fierce competition makes it inevitable for the drama side to be "drunk and afraid of the deep alley." However, nowadays, the escalating marketing means has not only helped the industry to explode, but also exposed more and more problems. What is marketing, what is "excessive marketing", and why does the industry need to grasp this "degree"? Through investigation, we found that superficial marketing chaos such as hot search and list brushing, water army control and evaluation are bringing deeper hidden dangers and harm to film and television creation.


24-hour "stalking" of the whole network, planting stalks and burying lines in the preparation period of the script

Film and television practitioners suffer from "anxiety" of hot search and out of the circle.


According to the "nomination" of netizens under the topic # Over-marketing won’t win the audience’s heart #, we have verified the marketing data of several film and television dramas: during the broadcast period, the number of hot searches of an online drama that was rated as "more hot searches can play cards" reached 1,300+,of which Weibo platform alone exceeded 800. Calculated, this 15-episode film and television drama has about 90 hot searches on the whole network, and the proportion is really amazing.



Another artist whose name appears frequently, whose recent hit works are also frequently searched on the list. According to incomplete statistics, the number of single-platform hot searches for this series has exceeded 300 in about two weeks. Of course, we also found the data of several "hot search regulars" in the same period of the show, and the hot search volume of the whole network has reached a similar level.


"Overmarketing" or "Really Out of Circle"? Naturally, it is impossible to jump to conclusions only by the number of hot searches. In the same comment area, netizens also had a heated discussion around whether the drama XX and XX really "exploded". Some people think that if the drama has a good reputation, it is understandable to make more efforts to promote it, but more voices immediately refute: this is not the reason why the starring actor creates a topic to brush the list with a little trouble!



It is not difficult to see that excessive marketing is making some works lose their popularity. But why are most drama parties still eager for this?


As one of the "hot searches" in others’ eyes, Ms. Wang, who is engaged in film and television marketing, bluntly said to us: "Sometimes I hope this marketing model will be’ eliminated’ more than anyone else." It is understood that the broadcast cycle of a drama is usually about 3 weeks. The "premiere day" is the most important announcement node of a work. For publicity, this day basically needs to be followed by the whole network 24 hours a day, paying attention to public opinions and topics, keeping up with hot spots in time, and adjusting the announcement rhythm.


However, with the increasing influence of marketing and data on the broadcast volume and investment promotion effect, the "24-hour" that needs to be watched is constantly lengthened in the broadcast cycle. Nowadays, in addition to the marketing plan that has been formulated in the early stage, the publicity department will always pay attention to the discussion of fans and netizens on the Internet, grab the content that has the potential to board the hot search, and then spread it through the topic.



We took the hot search data of the dramas nominated by netizens to Miss Wang, and she admitted that "it is indeed a very high number". However, as a "peer", Ms. Wang also made an analysis from another angle: "This drama is slightly different from other works on the market, because its number of episodes is very short, which means that there is no more time for it to ferment word of mouth during the hit period, so it is also a kind of idea to intensively create topics."


Creating topics to achieve hot search and out-of-the-box content dissemination has now quietly become the "ultimate goal" of some film and television projects. Ms. Wang revealed that in order to facilitate the creation of topics in the subsequent all-media marketing, some dramas have advanced the cycle of planting stalks and burying lines to the project preparation stage: "Now some publicity and marketing parties will start to intervene from the script stage and plan what plots or artists may be hot."



In her view, this seemingly "intentional" marketing is more harmful than the "trivial" topic that disgusted the audience — — The function of creation and publicity is "putting the cart before the horse", but content production serves "going out of the circle" and "hot search": "For example, for a while, it was quite popular for a long time, right? At first glance, they are all golden sentences, which are actually particularly abrupt in the play. " Ms. Wang said that this "strong output" style has been particularly favored by emerging media platforms in the past two years, which is also determined by the preferences of the audience.


Regarding the view that losing the popularity of the road and winning the hearts of the audience, Ms. Wang bluntly said that if "over-marketing" has become a "general trend", most of the authorities will acquiesce in this kind of gameplay: "I feel that it has become an obsession to be out of the circle and hot search, which is the anxiety and heart disease of everyone in the industry. As long as the data that bombing marketing can bring is greater than the so-called lost popularity, then this routine will never be eliminated. "


From "Overmarketing" to "Malicious Marketing"

Brushing the list and controlling the superficial chaos are creating deep harm.


In 2021, during the special rectification of "Clear Rice Circles", we conducted an in-depth investigation on idolize and marketing chaos in artists and fans. Nowadays, the problems exposed in the "over-marketing" of film and television works also tend to be "rice circle", or they have been interdependent and influenced each other for a long time.


Relevant people familiar with the matter introduced to us how some platforms can achieve marketing purposes by purchasing all kinds of data: the drama party can first buy a batch of marketing numbers, usually 5-10 in a group, and publish the same content in a centralized way, attracting users to turn, comment and praise a lot in a short time, and increasing the degree of topic discussion. If the heat fails to meet expectations, the marketing number will also find ways to control and evaluate it. This way, to a certain extent, can affect the platform algorithm and help marketing content get on the hot search. Once on the list, we will continue to spread the "square", buy users to increase original discussions on topics, further consolidate the popularity, and help the content hot search ranking continue to rise.



In addition to the number of hot searches, there are various scoring platforms that need marketing means "public relations". At the end of last year, Douban was once reported as "the water army’s brush quantity control and evaluation before the drama started". Although the platform made a statement at the first time, it also hammered the existence of abnormal scores in the drama evaluation system.



On the 17th of last month, Netcom Office released ten "Clear and Clear" special actions again in 2022, many of which involved the rectification of MCN organization’s content standards, comprehensive management of algorithms, and cracking down on traffic fraud, black public relations, network water army and other marketing-related chaos.


Screenwriters and film critics have always paid close attention to the series of chaos between the entertainment field and the Internet public opinion field in the era of big data. In an exclusive interview with us, he said that the marketing of film and television works, as a means TO C (user-oriented), is a normal business behavior to invest a certain cost in publicity, which is understandable. However, in recent years, especially after the rise of various platforms on the Internet, the purpose of drama marketing has changed from simple TO C to to TO B (enterprise-oriented). Many people use algorithms to manipulate data and increase the online "traffic" of film and television works or artists, thus improving their commercial value in disguise.


On the day of publication, the Central Network Information Office officially took the lead in launching the special action of "Clear 2022 Algorithm Comprehensive Management". Wang Hailin believes that the use of data algorithms to create and chase traffic is the core issue of over-marketing in the film and television industry in recent years. "In the past (due to the purchase and sale mode), people rarely did a lot of publicity and marketing for the series, but now they need it because it has traffic." He revealed that at present, many production companies have to brush their own evaluation on various platforms and scoring websites through marketing, "not only give their own works high marks, but even give other opponents malicious low marks in the competition."



In Wang Hailin’s definition, excessive marketing has developed into a malicious marketing. In order to create traffic, many hot searches are divorced from the content of the play and the acting skills of the stars, which even makes many viewers feel bored and puzzling: "Why do these boring contents have to be searched?" Because they want to keep the heat, this heat can be converted into commercial value. "


However, when over-marketing has long been out of the scope of works propaganda, it has become a new means to create heat and commercial value, and it is bound to trigger more behaviors that do not conform to the norms and even impact the "bottom line" in the industry: "Competitors and traffic people use marketing methods to suppress each other, amplify negative comments, and cause the public opinion environment to deteriorate, which also makes the public’s perception of the film and television industry very negative." Wang Hailin pointed out the deeper influence behind the superficial chaos, such as "brush quantity control and evaluation" and "data falsification".



As a matter of fact, when some playwrights and artists’ brokerage companies that are not properly marketed or even maliciously marketed still use traffic online to guide fans to control and comment, and brush up the list to create gimmicks, truly outstanding works have been "quietly" out of the circle with good stories, good acting skills and good reputation, and really won the audience’s love. Wang Hailin gave us an example. The TV series "In the World", which was popular some time ago, was not widely promoted on the online platform, but both the record-breaking ratings and the high degree of discussion in life proved that the drama was a real "explosion" in 2022.



At present, the special action of Qinglang in 2022 has been rolled out. Although various platforms have been rectified and inspected for related excessive and malicious marketing problems before, it is obviously difficult to achieve tangible results only by their own supervision. Wang Hailin said that malicious marketing works and artists still need to really hit the "sore spot", and those who have caused bad consequences to the industry should be given substantial punishment after investigation. "After last year’s action, some companies, especially traffic brokerage companies, did not see substantial disciplinary measures, but intensified. It is also necessary (relevant departments) to conduct more detailed management of malicious marketing and propose targeted measures. "


31-year-old beauty blogger broadcasts frozen eggs live. How difficult is it to just have a baby without getting married?

Original said elder sister elite said.

Frozen eggs are called the only regret medicine in the world.

With the increase of age, women’s ovaries are gradually aging, the quantity and quality of eggs are getting worse, and the infertility rate, abortion rate and the risk of abnormal fetus will increase. In order to solve this problem, frozen egg technology was born.

Frozen eggs came into public view because of Xu Jinglei. In the early years, in an interview with Lu Yu, Xu Jinglei admitted that she went to the United States to freeze eggs. She said, "It’s too easy. You can leave such precious things without doing anything. Why not do it twice?"

The picture comes from "Lu Yu You Yue"

Over the years, there have been reports in the media that single women have been refused frozen eggs.

Since the first "frozen egg case" in China in 2019, a large number of public opinions supporting single women have been spreading, and frozen eggs are obviously not a niche demand.

The picture is from The New York Times.

When the domestic policy becomes more and more restrictive, the outbound "assisted reproduction" market becomes hotter and hotter, and the tide of consumption upgrading driven by technology also comes from the complete change of individuals’ cognition of life reproduction.

It is precisely because of realizing the "benefits" of frozen eggs that more and more women want to buy this "regret medicine". Some of them have not found a suitable partner, some are not ready for childbirth, and some have poor ovarian function … But behind frozen eggs, there is actually the responsibility and love of contemporary women for bearing offspring.

Frozen eggs, also known as "frozen eggs"

The picture comes from the Internet.

31-year-old beauty blogger broadcasts frozen eggs live:

"Save the seeds of hope while you are young."

Molly is a famous travel blogger in Weibo. He is 31 years old. In 2019, she broadcasted the whole process of freezing her eggs live on Weibo.

"If you have a boyfriend, why do you still go to freeze eggs?" In the face of questions from fans, she replied, "I want to be a mother, but not now."

About two years ago, Molly was often urged to get married and gave birth, and she often considered the issue of fertility:

"Before the future children arrive, I will try my best to meet the standards of a mother, including economic aspects, how to understand the needs of children, communicate, set a good example, and how to communicate and cooperate with my partner."

She wants to get everything ready before welcoming the baby, but the ovary waits for no one. 25 -30 years old is the best childbearing age, and it is too late when she is ready.

It is out of responsibility for future children that she wants to freeze eggs. "Save the seeds of hope while you are young."

Image from @ molly Molly

When she showed her ideas to her parents and boyfriends, they couldn’t understand and even strongly opposed them. It took Molly two years to convince her family and boyfriend.

She spent a lot of energy in persuading this matter. At first, she told her parents, "I don’t want children at all", then slowly transitioned to "I can adopt children" and finally told her parents that "I can freeze eggs". After slowly lowering her parents’ psychological expectations, she finally achieved "understanding".

So, her "frozen egg trip" finally took place.

Before taking eggs, women need to take and inject ovulation-promoting drugs to make multiple follicles develop in advance. Molly first had a B-ultrasound in the Shanghai hospital and sent the report to the American doctor. Then the doctor filled the medicine according to her actual situation, and Molly himself injected it on time.

Every morning at 9 o’clock, she gives herself an injection.

Molly gives himself injections on time every day.

In addition, in order to keep the ovaries in the best condition and discharge the best eggs, she went to bed on time before 12 o’clock every day for three months before taking eggs, went to the gym for running and fitness, and maintained aerobic exercise for half an hour.

Molly called eggs "eggs"

She insisted on running for the sake of "eggs"

Even, she has made preparations for raising a baby in the future, and she carefully pays attention to the communication between parents and children around her.

While running by the river, Molly met a father and daughter. The daughter wanted to do something, but her father didn’t agree. Dad lured his daughter to the place he wanted her to go with a lollipop, but ignored her real needs. Molly thought, "This is not right. I don’t want to be such a mother. She still has a lot to learn in parenting. " /Image from @ molly Molly

After several weeks of drug ovulation, Molly’s left and right ovarian follicles add up to more than 30, and the number has met the surgical requirements.

She ended her treatment in Shanghai and came to the United States to prepare for the final egg retrieval operation.

Image from @ molly Molly

When she arrived in the United States, Molly was both excited and anxious. She had a series of tests, such as blood drawing, B-ultrasound and preoperative physical examination.

On the screen of B-ultrasound, she couldn’t help laughing when she saw the unformed egg. "The first time others saw B-ultrasound, they looked at the baby. I looked at the unformed egg."

Image from @ molly Molly

After three months of preparation, we finally reached the most critical step: taking eggs. Under the guidance of B-ultrasound, the doctor inserted a long needle into the vagina, penetrated into the ovary, and sucked out the follicles containing eggs.

The operation lasted about half an hour because of anesthesia.

Molly felt no physical pain.

Image from @ molly Molly

The operation was very successful. The doctor successfully removed 17 eggs from Molly’s body, including 8 high-quality eggs that can be frozen. Only 2 eggs can be successfully "thawed" into fertilized eggs and make her pregnant.

These eggs will be frozen in a liquid nitrogen tank at MINUS 196 degrees Celsius. There they will go into a "dormant" state and stop their metabolism until one day, when Molly is ready to give birth, they will be taken out and thawed.

Although there are only two babies who will be called future babies, Molly is very satisfied. She feels that when the child was an "egg", she had fallen in love with him deeply.

After the release of "Frozen Egg" Vlog, many netizens praised it, and left messages saying "I feel the same way" and "I feel deeply touched" and "Come on, you will definitely be a good mother in the future."

In order to catch the golden period of the egg

She embarked on a difficult road.

Like Molly, 31-year-old Xu Zaozao wants to be a good mother in the future. She is a new media practitioner and has been drifting in the North for many years.

Xu Zaozao (first from the right) was interviewed by the media.

The picture comes from the wind video

When she was 30 years old, she had some anxiety. She could obviously feel the slow metabolism and began to gain weight.

At that stage, she had no boyfriend and her career was on the rise. In order to give herself a "baby insurance", she had heard of "frozen eggs" and she had the idea of freezing eggs.

She consulted a medical intermediary, and the price of freezing eggs in the United States was 100,000-200,000 RMB. "It is not so realistic for me to suddenly take out so much money."

Image from China News Service

Later, Xu Zaozao found a message: Experts estimated that the cost of domestic freezing was about 20,000 yuan.

So, she went to Beijing Maternity Hospital affiliated to Capital Medical University to consult about frozen eggs and had a physical examination. The examination results met the requirements for frozen eggs. Just as Xu Zaozao was happy, the doctor asked, "Are you married now?"

Image from China News Service

After learning that Xu Zaozao was unmarried, the female doctor immediately rejected Xu Zaozao’s request for frozen eggs. "Frozen eggs for unmarried women are not supported in China." The female doctor also persuaded: "Do you want to get married? Hurry to have children. "

"Unmarried boys can go for sperm freezing, but girls are not allowed to oocyte cryopreservation. I want to leave a guarantee in the golden age of eggs, why not? " Xu Zao Zao felt very angry.

She said: "I don’t agree with the fact that women’s right to make their own choices has been naturally abolished."

After careful consideration, she took the hospital to court for violating "general personality rights" (including reproductive rights, that is, the right to freely choose fertility and the right to freely choose fertility methods).

The lawyer told Xu Zaozao that he was not sure of winning the case, but Xu Zaozao insisted on appealing. Before the trial, she also sent 63 letters to the NPC deputies, but none of them received a reply.

On December 23, 2019, the "Frozen Egg Case" was opened. This case has aroused widespread concern from all walks of life. Before the trial, many media came to the scene. In front of the media, Xu Zaozao felt that "I have a feeling of standing with single women or women who are willing to give birth".

Xuzaozao (pseudonym)

The picture is from World Chinese Weekly.

During the debate during the trial, the defendant’s lawyer mentioned three points:

First, frozen eggs will delay the time for women to give birth, which will widen the age difference between parents and children, resulting in "menopause hitting adolescence".

Second, the ability of single-parent families to resist social risks is generally low.

The third is the risk of surgery. The first is the risk of anesthesia, and the second is that the gynecological examination in China is responsible for single women. (Generally) it is impossible to perform vaginal puncture surgery on unmarried women.

Xu Zaozao’s lawyer retorted: "Now that the divorce rate is so high, the number of single-parent families will increase, which should not let single births and frozen eggs take the blame. Regarding the risk, it can actually be solved by providing a preoperative risk notice. "

Image from interface news

On the day of the court session, Liang Jianzhang, founder and demographer of Ctrip, and Zhan Qingyun, doctor of law of Harvard University published an article entitled "The Right of Freezing Eggs of Single Women" to support Xu Zaozao. "The current law in China does not prohibit the reproductive rights of single women, so it is reasonable to respect the right of some capable women to choose another way to raise children."

As of today, the court has not pronounced a verdict, and Xu Zaozao is still waiting for the result.

After the media exposure, she was also under some pressure. Some people said, "Why did you sue the hospital? The hospital was also very wronged." "Are you a good lever? Why do you have to insist?"

However, Xu Zaozao insists on herself. "I just strive for women’s right to choose independently. If I lose, I will appeal again. I want to try all kinds of methods that I can try. After all, I have come here. "

It’s not easy to choose this road. She spent a lot of energy, time and money just trying to get a guarantee.

She said: "There are also many people who come to share the frozen egg experience with me, and they will encourage me. That is the resonance between women!" Everyone wants to guarantee future fertility in the golden age of eggs. "

Frozen eggs, to a certain extent, come from women’s sense of crisis about their fertility.

In Asia, a woman’s fertility is very important to her family. If she is unable to have children after marriage, she is likely to encounter a great family crisis.

The black line in the picture above represents the pregnancy rate.

It is true that in the biological sense of the school-age childbearing stage, friends around you will fall into various entanglements, and behind these troubles, the message of "not ready" is revealed.

Under the fast pace of modern society, we have not had time to understand all kinds of love and work, so we are pushed to the choice of marriage and childbirth by life.

Perhaps in this sense, "frozen eggs" are opening more possibilities for women’s life course?

Frozen eggs are not necessarily "regret medicine", but as ordinary women, we are encouraged by various frozen egg stories that people don’t have to force themselves to arrange "when to do things".

Modern women are already too difficult, why not give them one more choice?

The purpose of choice is to make life more colorful. No matter what kind of life we choose, as long as we can bear the consequences, there is no right or wrong.

Read the original text

What is "history"? What is "history"?

"History" in Chinese is both "old" and "new".

To say "old" is that some old scholars believe that the "History of the Three Kingdoms" annotated by Pei Songzhi is the source of the word "history".

His Biography of Master Wu records that Zhao Zi was an ambassador to Wei, and he was eloquent and convinced Wei Wendi Cao Pi. In the Note, Pei Songzhi elaborated on Zhao Zi’s response, saying, "The prince of Wu floats on the river with a million ships; Ren Xian can make use of his abilities, and he will keep his mind on the classics. Although I have spare time, I read a lot of books, collect historical records, adopt strange things, and it doesn’t work for scholars to find chapters and extract sentences.

Accordingly, the earliest "history" means "browsing historical records".

When we say "new", it is from the Ming Dynasty that "history" has a new meaning.

During the Wanli period of the Ming Dynasty, Yuan Lefan, a great scholar, wrote A Supplement to the Outline of History. Its "history" means "historical records".

In modern times, the meaning of "history" has changed again.

About the end of the Ming Dynasty, the Japanese reprinted A Supplement to the Outline of History, which was widely circulated in China. Its version was introduced into China in the late Qing Dynasty, which made the word "history" widely accepted. At this time, the meaning of "history" is similar to that of "words and things recorded in ancient books" in Chinese "history"

The Chinese character "calendar" is a simplified character, which has three traditional Chinese characters-"calendar" and "calendar", which is generally considered to be universal.

In fact, there are subtle differences in mutual meaning. What is connected with history should be "Guan", which means "through", "through", "universal" and "ranking".

Therefore, the ancients used the word "中中" to match "history".

The original meaning of "history" is official position, "holding in the hand", pictographic and knowing, indicating that "historian" is upright, and later extended to mean "what happened in a certain time and space in the past".

Now, if you ask what "history" is, it actually means this-"All the past is history".

In the west, for example, English "history" originally means "telling stories", and later it has the same meaning as Chinese "history"-"all the past is history".

Specifically, the meaning of the word "history" in modern times is divided into two levels.

The first level is "objective history", that is, what happened in the past.

In "objective history", it includes "broad history" and "narrow history".

"Generalized history" refers to the objective process of the movement and change of everything that exists objectively. Generally speaking, it includes natural history and social history.

For example, "the history of the universe" is all the "past" courses that the vast universe has experienced-whether people can recognize and understand it or not. This belongs to "natural history".

For another example, "human history" is all the "past" courses of the species "man" since its formation-no matter how much people have figured out. People have a society, which is "social history".

"Social history" or "human history" refers to the objective process of movement and change of human society from the beginning, which is usually called "narrow sense history".

"Human History" is the research object of "Anthropology" and "Anthropology Archaeology". "Social history" is the main research object of "history" and "sociology".

In addition, "narrow sense history" also refers to the history of the development and change of some objective things.

For example, the objective history of the development and change of the earth’s "biology" is the object of "biology" research; For example, the objective history of the earth’s "geography" changes is the research object of "geology" and "historical geography", and so on.

The second level is "historical theory", that is, human’s subjective cognition of objective "broad history" and "narrow history".

This kind of cognition, or covers a wide range, or the perspective is extremely concentrated.

For example, there is a great history written by Ming Xu recently in China, with the subtitle from the origin of the universe to human civilization and the English title of BIG HISITORY.

There is also a great history of everything written by David Christian, the pioneer of the Great History School abroad, with the English title A Big History of Everything.

However, other historical works in a narrow sense have a very concentrated perspective, such as "A certain dynastic history", "China iron history", "Medieval costume history" and "Xiongnu history", and so on.

Since the "historical theory" is people’s subjective cognition, firstly, the authenticity and total bias of the narrative are closely related to the author’s vision, position, materials and materials, which are bound to be limited by the times; Second, even if we take a realistic attitude towards "objective history", it is bound to be a process of approaching "historical truth" and the complicated reasons behind it.

What is "history"? It is the "historical truth" of all "objective history"

The purpose of human cognition of "objective history" lies in more, more complete, more detailed and truly understanding of "historical truth" and drawing regular knowledge from it.

As for the so-called "history is a little girl dressed for everyone", as Hu Shi, the well-known originator of China, said, including the German Nazi Piper’s saying that "history is written by winners" and so on, all of which can be attributed to the typical idealistic view of history, so there is no need to talk more.

Lu Ruozheng and Li Yize, students of Class 6, Grade 9 in Tianshui No.7 Middle School, and an Xianghui, the instructor, connected the experiment with life. Anthocyanin solution was extracted from fresh purple cabbage and added to different food solutions respectively, and the acidity and alkalinity of food were reflected by observing its color change. Their scientific and technological innovation work "Exploring the Acidity and Alkalinity of Food with Anthocyanins" won the special prize of middle school group in the seventh Tianshui Youth Scientific and Technological Innovation Competition.

Lu Ruozheng, a student in Class 6, Grade 9, Tianshui No.7 Middle School, said: "The main significance of testing the acid-base balance of food is to let us know the acid-base balance of food, so that we can remind people to make a healthy diet plan, so that people with alkaline constitution can eat more acidic food, so that people with acidic constitution can eat more alkaline food, which will help us maintain the acid-base balance of human body and thus maintain normal physiological functions."

Pu Bolin, Class 8, Grade 8, Longyuan Middle School, Maiji District, showed his award-winning work "Smart Butler System Based on Arduino". Pu Bolin said: "This scientific and technological innovation work combines artificial intelligence and Internet of Things technology, and opens and closes the door through face recognition technology and mobile phone remote control. The work won the second prize of the 7 th Tianshui Youth Science and Technology Innovation Competition."

Behind the interesting and creative science and technology works is the "inspiration light bulb" that a famous student constantly explores, and it is inseparable from the investment and support of Maiji District in the education of scientific and technological innovation for young people. In recent years, Maiji District has continuously expanded its popular science positions and extensively carried out a series of popular science activities, resulting in more and more fruitful achievements in science and technology education. In the 7th Tianshui Youth Science and Technology Innovation Competition, 112 works were awarded in Maiji District. Among them, there are 8 grand prizes, 28 first prizes, 41 second prizes and 35 third prizes.

Feng You, director of the supervision office of the party members of the Maiji District Education Bureau, said: "In 2023, primary and secondary schools and kindergartens in the whole district invested more than 3.6 million yuan in science and technology education, and the conditions of science and technology education in various schools were further improved. Our district actively participated in scientific and technological innovation competitions at all levels. In previous municipal competitions, the number of participants and winners ranked among the top in the city. "

Improvement of lung cancer staging by PET AI model

A research team in Germany said that an artificial intelligence (AI) model based on routine data of F-18 FDG-PET/CT scanning can improve the accuracy of staging treatment for patients with metastatic lung cancer.

A research team led by Dr Julian Rogasch of Charette Medical University in Berlin has developed a machine learning tool to help evaluate mediastinal lymph node metastasis in patients with non-small cell lung cancer (NSCLC). They found that the model was more accurate than the visual score of PET, and suggested that it could help doctors make more accurate treatment plans. Their results were published in the February 23 issue of the European Journal of Nuclear Medicine and Molecular Imaging, and they wrote that the model can be used as a network application to further promote verification.

Dr. Rogasch and his colleagues wrote: "This model was developed for routine clinical care, and the probability of N2/3 disease (that is, whether there is N1, N2 or N3, which is the key to determine stage II and III diseases) was estimated according to the results of F-18 FDG-PET/CT. This is based on routinely available variables, most of which are already part of the F-18 FDG-PET/CT report in routine clinical nursing. "

In patients with non-small cell lung cancer, accurate imaging of thoracic lymph node metastasis is very important for treatment planning. The authors explain that patients with N0/1 disease usually need surgery, while patients with more extensive N2/3 disease need multimodal treatment. They pointed out that although F-18 FDG-PET/CT is the most effective method, it may be limited by false positive results, and invasive biopsy is often needed to confirm suspicious cases.

In order to evaluate the value of AI model designed to assist these cases, the researchers collected data of 491 patients with non-small cell lung cancer, who were imaged before treatment with analog PET/CT scanner or digital PET scanner. According to the scanner used, patients were divided into training queue and verification queue. There were 385 people in the simulation training and testing queue and 106 people in the digital verification queue.

Forty clinical variables, tumor features and image variables, such as F-18 FDG radioactive tracer uptake (SUVmax) of lymph nodes, were collected, and different combinations of variables in several machine learning methods were compared. The researchers chose a gradient enhancement classifier with 10 eigenvalues as the final model.

The above picture comes from a 54-year-old woman in a training and testing cohort, suffering from G2 adenocarcinoma in the right upper lobe (44 mm). The uptake of F-18 FDG in several hilar and mediastinal lymph nodes was higher than that in normal liver (PET score was 3). The blue arrow shows N2 paratracheal lymph nodes with a short axis of 7 mm and an SUVmax of 3.5. According to the visual assessment, this case is suspected of N2 disease. According to the gradient enhanced classifier model, the probability of N2/3 is only 0.17. Ultrasound-guided bronchial puncture biopsy of LNs at the same hilum, paratrachea and carina confirmed that the patient was NO. Image provided by European Journal of Nuclear Medicine and Molecular Imaging through CC BY 4.0.

The gradient-enhanced classifier model shows that the AUC in the training and testing queue is significantly higher than the visual PET score (0.91 vs.0.87, p=0.003), and the AUC in the verification queue is slightly higher (0.94 vs.0.91, p=0.023).

It is worth noting that the gradient-enhanced classifier model is superior to the visual evaluation of radioactive tracer uptake in lymph nodes above mediastinum, which is the most common and effective diagnostic threshold in visual F-18 FDG-PET/CT evaluation. They also reported that the coordination of PET images between the two scanners does affect the visual evaluation of SUVmax and lymph nodes, but it does not reduce the AUC of the model.

In order to facilitate further verification, the team has published all variables and machine learning codes as open data and used a web application on GitHub. The network application requires users to input 10 eigenvalues to calculate the prediction probability of N2/3 disease.

Dr. Rogasch and his colleagues said that the research results show a good prospect and deserve further study.

They concluded: "We look forward to the external verification and validity proof in the intervention test."

Reply to comments on Wen Xin’s words

There are still 9 days before the release of Baidu Wenxin’s words. The essay I sent before about Baidu Wenxin’s words was very heated. Based on your comments, I have the following questions. Although I didn’t reply at that time, I will summarize them as follows:

1 Many people are not optimistic about Baidu Wenxin’s products, especially Baidu’s independent innovation mentioned in the article, and many people even scoff. Baidu’s attitude towards artificial intelligence is "All in". In 2013, the world’s first deep learning research institute was established. It has been in this field for 10 years, and the accumulated R&D investment in the past 10 years has exceeded 100 billion yuan. In 2021, core R&D accounted for 23%. By 2021, the number of AI patents held by Baidu was in the top two in the world, with more than 9,000 cases. Do you think Baidu’s AI products are just research and development patents? In terms of software, Baidu has the intelligent transportation scheme Apollo RT6, the self-driving travel service platform "Radish Run", the world’s first AI aerospace model under the Wenxin model, AI digital people Hijiajia and Du Xiaoxiao, and in terms of hardware, it has added intelligent fitness mirror M30, small voice intelligent alarm clock and small big screen eye protection learning machine P20, and small audio. After years of AI technology accumulation, Baidu Wenxin stood at the top of the wave and suddenly looked back.

Many people have a bad impression of Baidu, because Baidu started out as a search company and did a lot of mercenary things because of profits. Now, Baidu’s "All in" artificial intelligence is a huge engine for future economic growth, thus fundamentally improving production efficiency, liberating people’s physical strength and brain, accelerating innovation, expanding application scope and pushing social development into a new stage. Artificial intelligence is the core technology of the fourth scientific and technological revolution, which provides a historic opportunity for industrial upgrading and a huge engine for economic and social development. By 2030, the contribution of artificial intelligence to the world economy will reach 16 trillion US dollars. By 2035, artificial intelligence is expected to promote China’s labor productivity by 27% and China’s GDP growth by nearly 2%. As the strongest artificial intelligence company in China at this stage, Baidu has a long way to go.

Some people think Wen Xin’s name is ugly. Here, I have to say that Mr. Li Yanhong of Baidu, although in the most advanced technology industry, is brilliant. Baidu "even though you are looking for him for thousands of Baidu, suddenly looking back, the man is in the dim light", Feijiang "smells of flying oars, and the literary heart and the literary heart say a word," Wen Xin Diao Long ""The mind is born, the words are civilized, and the way of nature is also. " "A word with less meaning is meaningless, and a long sentence is a hindrance." These names are full of ancient romantic feelings.
