It’s really not that I don’t know. It’s a shock. In such a team, if you want to get hands-on and operational opportunities, you have to practice secretly and read more books in order to be able to compete in such a big competitive environment. Next, I got such a tiny chance.

Unlike before in the Eighth Hospital, in Cai Dongfan's group, there are two superiors, Cai Dongfan and Luo Yun, and Du Yanjun, a graduate student from the undergraduate department, plus two regular trainees, Zhou Cheng and Zhang Zhengquan. No matter what, they can get started. Opportunity.

Moreover, the above preparations are only temporary clinical preparations. It is possible that postgraduates in the same clinical group went to their respective scientific research groups or laboratories after leaving the department.

Some graduate students went to the laboratories of other departments to do experiments and became one of the laboratory research groups of other departments.There are also some orthopedic laboratories, and personnel from foreign departments are doing experiments...

One person, two beds!

Most of the rest of the time is spent studying, reading clinical articles, reading articles on basic scientific research, and doing experiments.

Maybe you slack off for a while, and you will be left behind by others, and you will really compete!

Zhou Cheng licked his tongue, and then circled the four people in his group.

Zhou Cheng followed Ding Dian, and Ding Dian, as the 'leading sister' of one of the groups, brought three people with him!

Zheng Kangqiao, direction, Gongsun Su!

Zheng Kangqiao, a second-year postgraduate student, is Associate Professor Du Kunning's postgraduate student. It is said that he is the fifth postgraduate student of Associate Professor Du Kunning.

Gongsun Su, a first-year graduate student, is a postgraduate student of Chief Resident Han Xiaoming!

Zhou Cheng heard it right, Han Xiaoming became the chief resident in the second year of his employment, and he also obtained the qualification of a master's tutor, and this year he won a master's degree.

Without him, he won the National Natural Science Youth Fund in the first year after his Ph.D., and, during his master's period, he began to publish articles crazily.

The number of articles today, including meta-analysis and bioinformatics analysis, adds up to more than 40 articles, which is more than the total number of Professor Lin Ziyuan, and he was also a very powerful person in clinical practice!

He has the experience of studying abroad. In addition to being a regular employee, he is also a staff member of Professor Lin Ziyuan's postdoctoral mobile station!

Therefore, we won the number of hospital stays.

Immediately arranged for the general inpatient, master tutor, and had the first student!

Lu Mo, the attending physician, only got the qualification of tutoring postgraduate students this year, and he hasn't taken any students yet!

The king of the king of scrolls definitely has a place for Han Xiaoming!

Gongsun Su, the great disciple of Kaishan Kaijuan, the King of Juanwang...

Zhou Cheng stayed at home for a while, then took a taxi and rushed to the destination. After arriving at the destination, he sent a message to Zheng Kangqiao saying that he had arrived and waited for them first.

However, what Zhou Cheng didn't expect was that Zheng Kangqiao and the others arrived earlier than Zhou Cheng.

After Zheng Kangqiao sent Zhou Cheng the name of the box, he asked Zhou Cheng to find it by himself. Under the guidance of the waiter, when Zhou Cheng arrived in the box, he saw the three of Zheng Kangqiao 'talking nonsense' there.

There is a round table inside, a set of tea sets are placed on the round table, a teacup is placed in front of each person, and there is an empty teacup.

I don't know who brought a projector, and it was projecting on the wall, it seemed to be an article in English, and then Gongsun Su was sitting there, pointing with the mouse.

After Zhou Cheng pushed open the door, the big guy paused for a while, and then asked Zhou Cheng to sit down.

After Zhou Cheng sat down, Gongsun Su said: "Brother Cheng is here, Brother Qiao, Brother Xiang, you two give me some advice, see if there is anything that needs to be changed, my teacher asked me to give you the article first have a look."

"If there's no problem, I'll send it to my master for review. Thank you." Gongsunsu cupped his hands very politely and bowed to everyone!

Zhou Cheng was really confused by this action.

Is this really worthy of being a student of King Juan?

It's only been a few months since I entered school, and the article has already been written?

Zhou Cheng took a look, the article written by Gongsun Su was a net-meta!That is, mesh meta!

Meta-analysis is an article style that became popular about five years ago, and network meta-analysis is an extended version of meta-analysis.The efficacy of three or more interventions can be compared simultaneously.

This kind of article is very difficult to write.

Fang Xiang asked: "Gongsun, the foundation of your article is still very good, it just depends on the level of journal you plan to publish?"

Posting articles of different levels requires completely different content and article formats.

Gongsun Su said: "After reading the first draft, my teacher said that I can submit to JAMA's sub-journal!"

When Gongsun Su said this, he was still a little shy, and seemed a little embarrassed.

"Farewell!" Xiang Xiang immediately waved his hand!

The corner of Zheng Kangqiao's mouth twitched, and he said, "Gongsun, you really think highly of us. JAMA is one of the four major journals. Even if it is a sub-journal, the impact factor is at least ten or more. You have to give this to Sister Ding Dian, or Brother Mao Ruijie is the one to watch it."

"They have such experience. The two of us haven't even voted for 10-point articles. Aren't you embarrassing us?"

Hearing this, Gongsun Su said, "Brother Qiao, Brother Xiang, stop joking with me. In fact, I want to submit to a four-point journal, but my teacher won't let me post it. My format is based on Written in the style of their previous articles!"

Different journals have different manuscript quality and format.

The higher the level of the journal, the higher the quality of the required articles, and the higher the requirements for the content of the articles!

After Gongsun Suyue said that, Xiang Xiang said: "Then we don't dare to say anything more, I can only say that brother Ming is awesome."

"Really, Gongsun, I really suggest that you send it directly to your teacher to read directly. I can only say that you can try to use R language to process and polish it. This is better than the visualized graphics processed by Rev. A little more beautiful and comprehensive.”

R language and Rev are tools for article processing.

"For the R language, I don't know this. Brother Xiang, I heard that you can use Python. Do you still have such learning materials? Can you send them to me?"

"Okay, I'll send it to you later."

"Then if you want to submit to a sub-journal of JAMA, I suggest that you read more about the specific format of the meta-analysis of the target journal, and it is best to make a similar treatment!" Fang Xiang could only give his helpless opinions.

Generally speaking, people who have not posted high-scoring articles are rarely able to give more practical suggestions.

Zhou Cheng looked at these few people and dared not speak.

I just remembered what Dong Yuhai said before. I thought Dong Yuhai was modest before, but judging from the current situation, what Dong Yuhai said before is probably all from the bottom of his heart.

SCI articles are originally among the article types, which belong to relatively high-level journals. Under SCI, there are CSCD, statistical source journals, and provincial and municipal journals.

After quietly watching several people pretending to be coercive for a while, finally came to the part of ordering, Zhou Cheng didn't say much!

However, after Gongsunsu put away the computer, everyone changed the topic to daily communication. During the conversation, Zhou Chengcheng discovered that, in fact, Gongsunsu and the others had quite different personalities.

Zheng Kangqiao is a chatterbox, very outgoing, and has a wide range of knowledge. No matter what the topic is, he can get a foot in the door.

Astronomy, the entertainment industry, and the international situation are all discussed.

In the end, for some reason, when it comes to the culture of country R, ​​Zheng Kangqiao is even more of a master. He has many teachers, a thick skin, dares to say anything, gives advice on adultery, and is knowledgeable and strong. (no typos)

As for the direction, it belongs to the kind that is more introverted and has a more easy-going personality. Anyway, it can listen to anything and talk about everything.

There is a rather peculiar temperament, which makes Zhou Cheng a little puzzled.

Gongsun Su belongs to the kind of person who likes low-key Versailles. He seems to say it casually, but in fact, he is all pretending.But, his fork is not the same as that intentionally.

He is not domineering, but occasionally between words, there will be a look of self-confidence, self-confidence and not domineering!

However, intentionally or not, the three of them did not change the topic to a professional direction, and looked at Zhou Cheng with a hint of fear in their eyes.

When Zhou Cheng was looking at them, they were also looking at Zhou Cheng.

The four of them chatted fairly well, and they agreed to go out for dinner together next time they had a chance, and then they left separately.Only then did Zhou Cheng realize that all three of them had bags, and he was the only one who came empty-handed.

And the few of them would go back to their respective research groups after eating. Zhou Cheng couldn't find such a large team, so he had to go back.

……

After saying goodbye to the three of them, Zhou Cheng's expression gradually became serious.

In his previous thinking, he only thought that his current strength was already good. After all, he possessed more than 100 perfect-level skills, but looking at it now, it seemed that he had acquired these skills himself.

All can only be regarded as a senior technician!

As for how to open up new fields, how to forge your own path, and climb your own mountain, such methods and approaches are not well mastered, and you are not clear about your own direction!

In the previous unit, Zhou Cheng received the concept that scientific research is useless!

What's the use, it's all just talk on paper.Talking in general terms has no effect on reality, nor can it make your surgery better, nor can it cure diseases better.

However, in the eyes of Zheng Kangqiao and others, they don't think so.

Because they have a relatively deep-rooted concept from the bottom up, that is, no matter how useless these things seem, someone must do them. If everyone does not do them, the progress of medicine will stagnate. !

The so-called theory that scientific research is useless is just saying that grapes are sour!

Scientific research is definitely useful. Climbing to a higher mountain will only broaden your horizons.

What is looking for abuse is to make you gradually realize your own insignificance, and you will find that there are all kinds of doubts in the medical knowledge you read every day, even the common sense of medicine!

And it is precisely because of this in-depth understanding that the gradual lack of self-confidence is the source of your self-confidence!

The ignorant are fearless, that's bravery!

Those who know themselves are humble, it is not timid, it is because you are yearning for a higher place in the process of gradually climbing the mountain, that is a kind of obsession!

Compared with the entire universe, human beings are insignificant, and compared with the pinnacle of academic knowledge, human knowledge is insignificant!

"In the eighth hospital before, there was only one teacher Luo Yun, and then Yang Yifeng who broke in suddenly, opened my horizons."

"It's a pity that I haven't been to the Affiliated Hospital of Shonan University to see what's going on. However, I have only been here for three days, and I found myself a little drifting, and even started to think about things that I don't know."

"But I still feel that this kind of environment, such friends, such competitors, such partners, and such a team are the most comfortable."

"Many people are excellent. It is not that difficult to admit that others are excellent. The only thing to do is to gradually become excellent. Scientific research is not a high-level thing, nor is it useless."

"It's just a scientific method. Scientific researchers just use scientific methods to broaden their cognition."

"It's not great, but it's not small either." Zhou Cheng's mentality became more and more stable.

Zheng Kangqiao and Fang Xiang went to their scientific research group to do experiments, Gongsun Su was going to read articles for his teacher, and Zhou Cheng had nothing to do. In the world, a door opened...

Chapter 2 is played on the spot!

After returning to the rental house, Zhou Cheng was not in a hurry to open the data that Dian Dian gave him before, but first recalled the basic skills he had acquired!

Medical statistics (skilled), medical epidemiology (skilled).

Scientific research is not something lofty, nor is it metaphysics that exists apart from reality!It is a down-to-earth process of exploring the possible answer to a question through certain methods and experimental methods.

When writing an article, no matter what kind of article it is, in fact, the two disciplines of medical statistics and medical epidemiology are the basic methods. To write a good article, these two knowledge must be solid.

At least in the process of writing medical-related articles, a solid theoretical foundation is required.

Theory guides practice——

The definition of medical statistics is a subject that uses the principles and methods of probability theory and mathematical statistics, combined with medical practice, to study the collection, analysis and inference of digital data.The main object of medical research is the human body and various factors related to human health.

The definition of medical epidemiology is a discipline that explores the distribution of diseases and health conditions in the population and their influencing factors, and explores the strategies and measures for disease prevention and health promotion.

To put it more generally, the direct object of the science of medical epidemiology is the crowd, and the direction of the subject is set up among the crowd to obtain basic data.After obtaining the basic data, it is necessary to use the method of medical statistics to process the data into conclusions with practical medical significance!

To put it more simply, medical epidemiology is to digitize disease conditions, while medical statistics is to abstract and theoreticalize data!

Any article, in the final analysis, no matter how it changes, it will remain the same!

However, although the basics are enough, this applied process still has to be walked slowly step by step.

This process is like the decoration materials have arrived at home, but how to decorate and how to decorate on the wall is a procedural technical problem.

Basically, all medical undergraduates will understand medical statistics and epidemiology, but whether they can be applied flexibly is another matter.

Of course, what Zhou Cheng is thinking about now is not this. He thinks that if he writes a treatise-type article directly, it may be due to his lack of skill. meta-analysis or review.

Try the whole process of writing an article first, and after you are familiar with the whole process, start writing articles of the type that are more difficult than meta-analysis. In this case, you have completed the previous accumulation.

If you have to hardcore basic research articles, it is not impossible, but it will definitely be revised many times.

Sharpening knives does not miss woodcutters.

Now that the decision is made, if you want to study hard, you must first sharpen your tools if you want to do a good job!

Meta-analysis is not a basic course of the subject of medical statistics, at least in the course of undergraduate teaching, there is no examination.It's just that although you don't participate in the end-of-semester exam, it is a relatively simple and easy-to-understand subject for you to participate in social exams.

Meta-analysis, Meta-analysis, is a statistical method used to compare and synthesize the results of research on the same scientific issue. Whether the conclusion is meaningful depends on the quality of the included studies. It is often used in quantitative combined analysis in systematic reviews.

By integrating all relevant studies, health care effects can be estimated more precisely than individual studies, and it is easier to explore the consistency of evidence across studies and the variability between studies.

When the results of multiple studies are inconsistent or have no statistical significance, Meta-analysis can be used to obtain statistical analysis results close to the real situation.

Medical statistics is a discipline of evidence-based medicine. In terms of the classification of evidence in evidence-based medicine, meta-analysis is a relatively high reliability.

This is a discipline that has only emerged in the last 20 years. Its main method of use is to reuse the data of previous research, especially the data of randomized controlled trials (RCT). By integrating the data of multiple RCTs, more Believable results.

Because of the emergence of meta-analysis, many previous RCT articles have regained new vitality.

However, due to the emphasis on scientific research and the development of medical statistics in the past ten years, meta-analysis has gradually begun to flood, and the simple two intervention measures have been difficult to meet the needs of the development of the discipline.
