After a while, Li Zhongyue sent a message to Zhou Cheng. It was a few documents with some text at the end.
"Senior Brother Zhou, in fact, I usually collect some ideas for the type of articles you mentioned. I take the time to write these articles. Senior Brother, can you see if they are suitable?" Li Zhongyue's tone was extremely careful.
one two three four!
Four documents, each with its own title.
One is a case report.
letter!
Systematic review and meta-analysis.
Clinical RCs (retrospective study), Department of Hematology.
Zhou Cheng was stunned for a moment, then began to edit the information and asked: "When did you have time to write so many articles? Aren't you working part-time?"
"When I had time, Brother Zhou, I did the data collection, data processing and drafting of these articles all by myself. I own all the copyrights and did not copy anything." Li Zhongyue thought Zhou Cheng was considering this.
This is a question, so respond with caution.
You TM?
Zhou Cheng suddenly felt like he was hit by dimensionality reduction. You have a part-time job, studying, and still have time to write so many articles. How much more time do you have to leave?
"Okay, I'll take a look first and then tell you." Zhou Cheng finally realized the benefits of having someone 'dedicate' the article to him for review.
There is only one article he has written so far, and others are writing data. But Zhou Cheng has read a lot of literature. When he usually expands the direction of simulation and ideas, there are at least a thousand articles.
.
However, reading articles written by yourself is completely different from reading literature.
Zhou Cheng, who is proficient in professional medical English, quickly finished reading this case report.
A very interesting case is a case where oxygen embolism suddenly occurred during shoulder arthroscopy, and was identified in time and rescued.
Extremely rare.
The definition of embolism is that an emboli blocks the lumen of a blood vessel, causing embolism and affecting blood circulation. Emboli can vary, and common ones include thrombus, fat, etc.
Air embolism is also a relatively rare type of embolism, and oxygen embolism is even rarer. As a case report, it is quite satisfactory.
The structure of the article was very proficient. Li Zhongyue must have written articles before. However, his English expression was a little unauthentic, but it was innocuous. Zhou Cheng drew it out, made a review mode, and then typed it back to Li Zhongyue.
, modified a bit.
The key part of the case report is the description of the symptoms after the disease occurs and the analysis of the diagnosis and treatment ideas, so that others who encounter similar situations during surgery can serve as a reference!
Zhou Cheng has read the most case reports, because all kinds of strange and special cases are exactly the materials for his study and reference. Basically, he can find both common and uncommon clinical cases.
Li Zhongyue probably has never written a case report, so some of the formats are slightly wrong.
After Zhou Cheng reviewed it one by one, he sent back the first article, saying: "The overall structure of this article is fine, and the views are very innovative. In terms of data, you must check it again and again.
So that you can be ready to take out the raw data at any time.”
"In addition, a problem with this article is its ownership. You are not the dominant player in the handling of this case, right? Have you discussed it with the professor who handled this patient?"
This is a very important question. Logically speaking, these data are private cases under the professor's group. If you are given open permission in the case database and you can query it, then it is naturally good and others will not say anything.
But if it cannot be found, problems will arise if you do not reach an agreement with the professor when providing the original information, and others will not give you the information.
Li Zhongyue said: "Brother Zhou, I was the first to identify this patient's oxygen embolism, so the professor I was working with at the time gave me all the data on this case."
"I just kept putting it off and said it wasn't finished yet. When I asked the teacher again later, he had almost forgotten about it."
Zhou Cheng's expression flashed, "That's it."
Li Zhongyue was unusual. He was able to consider this kind of oxygen embolism immediately. If this was the case, it would not be surprising that the professor who was the surgeon would give him the case.
"You should discuss it carefully with the professor. This kind of case report has little effect on us personally. It can only be used as a number of articles, and it will not be published in journals with high impact factors, so it is unnecessary."
Zhou Cheng decided to persuade him.
Zhou Cheng knew that Li Zhongyue had so many articles. The reason why he didn't use them as a certificate of investment was probably because his previous articles had lost the bonus and he was short of money, so they couldn't reach an agreement.
However, some money and some data can be taken and used, but for some controversial data, it is better not to cause trouble on yourself.
"Well, okay, senior brother. I understand." Li Zhongyue replied.
Zhou Cheng then continued to tell Li Zhongyue to take a good look at his review comments. He could revise them or discuss them with him...
At noon, Zhou Cheng had just reviewed the second article and felt a little dizzy.
The second article is letter.
Letter, in fact, is looking for errors in an article published on a well-known article. Then, what Li Zhongyue is looking for is some errors in an article published on nature!
You can't write this randomly. Although Li Zhongyue himself looked for references, sometimes the references you refer to may not be credible.
Compared with the intensity of review by Nature's editorial department, articles in other publications are not credible.
After carefully reading the original text and then looking at several articles quoted by Li Zhongyue, Zhou Cheng frowned.
It's very troublesome. The references are sufficient and very classic. However, these references lead to many other points of view, so you need to read the references of the references.
The existence of letter itself is to correct the article and make the quality of the article better, not to find faults.
However, the teams that can publish Nature are not niche figures. You can make trouble for others, but you have to have a very good reason.
Therefore, the review of this article was troublesome to Zhou Cheng.
While An Ruo was resting and eating, he and An Ruo chatted for a while and talked about Li Zhongyue.
An Ruo heard this and sent a message: "Li Zhongyue? Why do I feel that this name sounds familiar?"
"Zhou Cheng, wait for me."
An Ruo is actually familiar with Li Zhongyue? What's going on?
Zhou Cheng actually doesn't gossip about other people's personal affairs. Including his previous relationship with Zhang Zhengquan, he didn't ask Zhang Zhengquan about his family background for more than two years. He just regarded him as a poor man, and then he was sucked into it.
About five minutes later, An Ruo wrote back: "Zhou Cheng, how come Li Zhongyue is your junior brother?"
"This person's reputation is not good. One of my classmates said that he reported his teacher before, so in fact, he is very utilitarian."
"I don't know the specific reason. It seems to be due to the distribution of rewards given by the school after the article is published. The ownership of the article belongs to the corresponding author. This is an unspoken rule in the circle!"
"Although that professor was later dealt with, he didn't spit out a penny."
"Li Zhongyue was supposed to graduate last year, but after graduation, no one dared to ask for him during the postgraduate entrance examination. How come he was assigned to the Eighth Hospital this year?"
Zhou Cheng was stunned for a moment. Does Li Zhongyue have such a past?
However, Zhou Cheng didn't think Li Zhongyue looked like this kind of person.
However, in his case, for money, it is possible.
Then you should be careful, lest you be forced into selling out by this!
"I don't know. Anyway, it was given to Teacher Cai Dongfan, who is now my junior brother, and I am guiding him. I have met him, and I think he is a pretty good young man. He is straightforward and has no twists and turns."
"An Ruo, from what you said, Li Zhongyue is quite famous, right?"
An Ruo edited the message and said: "The graduate student is in the same class as me. Of course he is famous. And the professor he reported to was planning to accept him as a master's tutor. As a result, he was stopped from accepting the master's degree for several years."
"I think you'd better be careful with people like this."
"Okay, I understand." Zhou Cheng did not forcefully instill other concepts into An Ruo.
Time passes and people's hearts are revealed.
We do not rule out using the most malicious intentions to speculate on people's hearts. Another sentence is that we do not rule out using the most kind intentions to consider the reasons behind it.
If the soul does not desire, the madness will have something to send it to.
Li Zhongyue doesn't seem to be a lunatic. What could make him report his teacher?
"This afternoon, I will go with Teacher Luo to meet a few people. They are the senior brothers or teachers I told you to visit when I was in Shashi."
"I can't have dinner with you again." Zhou Cheng honestly reported his itinerary.
An Ruo said: "I have gained weight after returning home for a few days. It just so happens that I lose weight and eat weight-loss meals at night."
Zhou Cheng's heart moved: "Can we go have a supper together?"
"Okay, okay." An Ruo responded with a nod.
woman!
No matter how sensible she is, she is still a woman, and Zhou Cheng has now slowly figured out the psychology of this snack foodie.
…
At one o'clock in the afternoon, Luo Yun got up, opened the door, and saw Zhou Cheng in the living room with a sad face. He subconsciously walked to the refrigerator, but it was empty.
Opening the door of the refrigerator disturbed Zhou Cheng, who hurriedly raised his head and said, "Teacher Luo, there's something called rice bowl in the microwave. It might be a little cold, so give it a try."
Zhou Cheng was quite attentive. Luo Yun went straight to the kitchen, pressed the microwave, and then got another glass of water and walked towards Zhou Cheng.
"What's the matter, you're so worried?" Luo Yun sat down and looked at the computer screen in front of Zhou Cheng.
"A letter. I feel like there's something wrong, but I don't know what to say." Zhou Cheng turned around the computer slightly.
Luo Yun has published a lot of articles, and he should have read more articles than him.
"Who is so unlucky that you have targeted Kerswill?" Luo Yun was slightly startled when he saw the corresponding author of the article.
"Is this article the one published in Nature? Why are you finding fault with his article?" Luo Yun turned his head in confusion.
Generally, as long as articles in the industry are published in top journals, practitioners will download and read them immediately in order to understand the latest research and professional progress in the industry.
Therefore, Luo Yun has also read this article. It is a multi-center big data analysis article. It is a comprehensive analysis article and is quite well written.
"Does Mr. Luo know this professor?" Luo Yun was well-informed, and Zhou Chengduo asked. If he did, he would have to think carefully about whether to send this letter.
Networking in academia is also important.
Luo Yun shook his head: "I would like to get to know each other, but others may not be happy to do so. I have never studied abroad, but I am quite famous. When the Asian Orthopedic Academic Conference was held in Australia, Professor Maxwell seemed to be doing it.
Report.”
"But at that time, the level difference was too high and we had no chance to get to know each other." Luo Yun shook his head.
"This letter was not written by me, but by a junior brother of mine. It is precisely because the impact factor of this article is relatively high that I feel embarrassed." Zhou Cheng replied.
"Your junior brother?"
"Du Yanjun wouldn't dare to write a letter for a journal of this level. Your junior fellow student at Kyoto No. 3 Hospital wouldn't submit his article to you, right?" Luo Yun was curious and confused.
Then he directly moved the computer to face him. After reading a little, he also looked as sad as Zhou Cheng.
"This idea is a bit strange. But writing it like this can easily offend people." Luo Yun turned his head in surprise.
Zhou Chengcheng said: "Teacher Luo, I think the entry point and intention are both good."
"It's Mr. Cai's new master's degree student, named Li Zhongyue."
Luo Yun moved his eyes to the computer screen again, and while looking at it, he said: "Teacher Cai is also having a hard time. This Li Zhongyue, if I remember correctly, should have been quite popular in the Shashi circle last year.
That young man."
"Last year, because his own tutor lost the qualification to teach a master's degree, others had reasons not to accept him, but this year, if he still refuses to accept him, he will start to have objections."
"This student is ruthless enough. If he takes the school and reports it to the Ministry of Education's mailbox, it will be very difficult. After all, there is a precedent."
Luo Yun's calm tone made Zhou Chengdu look askance at him.
It turns out that it was based on this consideration. Li Zhongyue's talent is not low, and you can't prevent him from entering. Therefore, Cai Dongfan has become a trash can. What's wrong, just throw it at him?
Luo Yun then added: "But Teacher Cai's luck has always been really good. First he picked up your mistake, and then he was given a treasure."
"I'm a little jealous."
Zhou Cheng was busy talking to each other about business: "Teacher Luo, actually you are the biggest mistake that Teacher Cai picked up. If it weren't for you, I wouldn't be where I am now."
You can wear it a thousand times, but you can never wear it as a flattery.
After Luo Yun browsed several articles downloaded by Zhou Cheng one by one, he pushed the computer.
"This letter is very complicated to write, and there can't be too many words. It needs to be highly summarized and understandable. It's a fire."
"My suggestion is that you can contact the original authors of the articles you plan to refer to in your letter and ask for their opinions. In foreign countries, the academic circle is very fierce."
"I believe these two professors are happy to let you be a troublemaker and retract an article in Nature. Moreover, they will also give you a certain amount of help." Luo Yun suddenly gave Zhou Cheng this
suggestions.
Zhou Chengcheng was curious: "Didn't you say that there is academic freedom abroad? Is the competition still so great?"
"How can we form an academic circle without fighting? It's hard to distinguish right from wrong in academia, and everyone has different ideas. Whoever can dominate more will be able to become a classic."
"The pursuit of fame and fortune is the same no matter where you are." Luo Yun suggested this.
He added: "You just need to tell Li Zhongyue that this kind of letter may not necessarily be rewarded for publishing an article, but it is of great significance and will be very beneficial to his future growth and academic status."
"Although such a person is a genius, he is too extreme. You still have to be cautious, lest he misunderstands you for taking his money or something."
"This person should have sold articles." Luo Yun added another sentence.
Well, it seems that I still know too little about Li Zhongyue.
After that, Luo Yun returned the phone to Zhou Cheng, then stayed aside to eat.
Zhou Cheng continued to look at the system review and meta-analysis, while Luo Yun kept eating and said nothing. After eating, he shouted in the group.
After a while, he said to Zhou Cheng: "Everyone is almost here, let's go."
"Whether you can convince them with your strength depends on you." Luo Yun directly gave Zhou Cheng a very important task.
Zhou Cheng was stunned: "We haven't even had time to build this nude mouse tumor model yet?"
"Whatever we want to build, we have an experimental team. We can build any model. Just use the ready-made ones." Luo Yun said lightly, as if this was a small matter.
Any time?
How much funding does your team have?
Inhumane!
Zhou Cheng knew how much it cost to raise a nude mouse. It might be cheaper than a rabbit or a pig, but it was also very expensive.
Moreover, once the rats are raised, there will be a batch, and a batch will be worth ten thousand as the basic number.
Zhou Cheng did not dare to say anything and followed Luo Yun silently.
Luo Yun and Zhou Cheng took a taxi, and after going around and around, they came to a mysterious laboratory in the Ninth Courtyard.
Zhou Cheng only knew that it was on the twenty-fourth floor, but he completely forgot how he got up there.
At the door of the laboratory, Luo Yun opened the lock with his fingerprint, and then said: "This laboratory is now Chu Hanbo's personal laboratory. Even the professors can't compete with him."
"The main reason is that the impact factor of Chu Hanbo's previous articles is too high. He is holding back his big move. Otherwise, someone would have forced him to graduate."
"But after graduation, this laboratory will also be given to Chu Hanbo." Luo Yun explained, looking at Zhou Cheng's curious look.
Zhou Cheng had entered Zeng Lao's laboratory before. It was larger than this one but had a large number of people. However, this place was empty and as cold as a haunted house.
Luo Yun's words are not difficult to understand. It is not uncommon for some powerful doctors to lead their own teams.
Only at the doctoral level, you can have your own laboratory, and the salary is comparable to that of an ordinary associate professor.
Luo Yun and Zhou Cheng did not go to the experimental area, but to the office.
There were three people inside, and coincidentally, Zhou Chengdu knew two of them.
One is direction!
Direction, a name specially assigned by Chen Shengwu. Before, he was not a student of anyone. He was in the eight-year program and had not yet selected a tutor, or even decided on a department.
I am only in my fourth year of college this year and will soon be in my fifth year. I have been lurking in the Orthopedics Department of the No. 9 Hospital in Shanghai for two years. I studied medicine at home and completed all the undergraduate and master's courses in orthopedics before college. So not long after I entered the hospital,
I started to work in clinical practice.
In the basic medical school, he took thirty-five courses in one semester, and the scores in each course were above 90 points. In the first semester, he was either taking exams or on the way to the exams. I don’t know how he persuaded him.
of the Department of Basic Education.
Zhou Cheng was quite surprised to meet him here.
The other one is also an old acquaintance, the king of volume in the general hospital. One year after graduation, he directly became a master's tutor. He used to be in Professor Lin Ziyuan's group, and Gongsun Su below was Han Xiaoming's student!
The other one should be Chu Hanbo.
Chu Hanbo's age was about the same as Zhou Cheng expected, and he was about the same age as Luo Yun.
Luo Yun is also quite familiar with them: "Lao Chu, Xiao Ming, Xiao Xiang also came to the laboratory today?"
"This is Zhou Cheng." Luo Yun introduced to everyone.
Han Xiaoming took two steps forward and looked at the time: "Xiao Zhou, we have met in the department before. Brother Luo, I am on duty today, so I won't have much free time."
Xiang Fang also hurriedly came to say hello to Zhou Cheng: "Brother Cheng, long time no see!"
Chu Hanbo was the only one who didn't know Zhou Cheng, so he looked Zhou Cheng up and down.
After Zhou Cheng responded to Han Xiaoming one by one and found directions, he solemnly thanked Chu Hanbo and said, "Senior Brother Chu, thank you for your previous guidance."
Although he has never met Chu Hanbo, he called him and he still has his phone number.
Chu Hanbo is the most legendary senior brother in the Nine Academy of Demon City, and he has long been heard about it.
"Luo Yun, you told me that Zhou Cheng is very young, but you didn't expect him to be so young?"
"Everyone, let's sit down and talk." Chu Hanbo is relatively thin, but has a lot of spots on his face, making him look very mature.
"Xiao Zhou, you should be twenty-seven already, right?" Luo Yun asked.
"Come on, Teacher Luo, I'll invite you to celebrate my birthday together in a few days." Zhou Cheng was stunned. It seems like his birthday is coming soon. March 21st, today is the 19th.
If Luo Yun hadn't mentioned it, Zhou Cheng himself wouldn't have remembered it.
"Oh, that's just right. Our group hasn't gotten together for a long time." Chu Hanbo suddenly said.
"Old Chu, you've been sneaking away in the laboratory and not going out. Who are you hanging out with? Rats?" Luo Yun rolled his eyes, looking like a big brother.
The direction is here, the youngest one, when he heard this, he said: "Brother Cheng, I heard Teacher Luo say that you designed the experimental idea that was posted in the group last night?"
"Why haven't I heard you mention it before?"
Zhou Chenggong said: "Fang Xiang, we are almost the same age, so don't call us by your name."
"I was new here, so I didn't dare to do anything."
“It happened to be during this defense that I learned something about it, so I thought about it for a long time based on my own clinical experience, and then I came up with my current ideas.”
"After reading it with Teacher Luo, Teacher Luo thinks it's acceptable. Otherwise, it can only be regarded as a review and put into the graduation article library, and it will be dusted." Zhou Cheng gave Luo Yun a lot of face and was a little 'humble'.
.
Luo Yun told me that it could be appropriate for Versailles.
After writing the thesis, you came up with this idea. Are you angry?
Chu Hanbo and Han Xiaoming immediately rolled their eyes and glanced at Luo Yun, knowing that it was Luo Yun who secretly taught Zhou Cheng such mundane things.
However, Zhou Cheng's talent and achievements are obvious to everyone, so what he said is completely out of touch.
Being able to perform open reduction and internal fixation through small incisions, to be so mature now, and to open up such a big situation, he would be hypocritical to say that he is too modest.
Han Xiaoming joked: "Xiao Zhou has indeed learned a lot in clinical practice."
"Small incision open reduction and internal fixation is almost a cocoon that Professor Lin Ziyuan talks about in the department. This is competing with our sports medicine for food."
Sports medicine, why did it develop?
Its core essence is still to deal with soft tissues such as ligaments, meniscus, rotator cuff, and open reduction. Why is it a separate department?
Just two words, minimally invasive!
Nowadays, trauma surgeries have begun to engage in minimally invasive surgery. As a sports medicine profession that relies on minimally invasive surgery, it is natural to be prepared for danger in times of peace. What if one day, after small incision open reduction and internal fixation, a small incision ligament treatment surgery is performed, then sports medicine
Medicine will have to find another way out.
Of course, Han Xiaoming also added a certain amount of weight to Zhou Cheng.
No one is stupid. Although it was Mr. Zeng who took the lead and asked them to do it, there are definitely risks. Although the overall situation is important, if they can take a step back temporarily to avoid the sharp edge.
Everyone still cherishes their lives, but if they can really benefit the country and the people.
No Chinese is confused!
The Chinese people are so stupid. They can risk their lives just for the unity of the two characters. This is engraved in their bones.
If you are rich, you will help the world, and if you are poor, you will take care of yourself. This is integrated into the blood.
A name left in history, from ancient times to the present, no one can escape.
"I won't say anything else. Xiao Zhou, you can just briefly talk about your current thinking and specific details. We will study it slowly in the future. Then, we will perform tumor surgery on a group of mice."
"See if we can prepare the supporting equipment you need in our laboratory."
Luo Yun, he didn't come here today just to listen to business talk, he came here for more important things.
Zhou Cheng had already prepared the idea. During the previous defense, he explained to Mr. Gui and Mr. Zeng that he didn’t know why they had follow-up arrangements.
Maybe it was because he didn't think particularly highly of himself, but Zhou Chengcheng still sorted it out.
"Mainly through the following three aspects..." Zhou Cheng briefly explained for a while.
Everyone must have read the specific content, and Zhou Chengcheng did not elaborate on it again.
"The above is my general idea. However, I have not actually performed it yet. Based on some previous clinical operations, I think it is worth investing some confidence in." Zhou Cheng scanned several people one by one.
Chu Hanbo, direction, Han Xiaoming!
They are all first-class talents. If these people can live well, they will definitely have a greater future. There is no need to settle here!
The idea is very clear. If it were not clear, there would be no need for Zhou Cheng to come today.
"What about the operating equipment?" Chu Hanbo asked.
Zhou Chengcheng said: "Let's use local materials and use them for whatever purpose. Today is just an initial test of the plan, and I haven't made any particularly thorough preparations."
"Teacher Luo, what do you think?"
This is the core skill of Mr. Cai Dongfan who you taught me, Versailles.
There is no need to prepare, I am the biggest preparation when I come.
The corner of Luo Yun's mouth twitched slightly, wondering if he had taught Zhou Cheng a little too hard?
However, now that we have talked about it here, we still have to continue!
There are two types of laboratories, one is the basic laboratory and the other is the in vivo laboratory, which is the animal laboratory, but it is upstairs.
Chu Hanbo only has his own basic laboratory. The animal laboratory is shared, but everyone raises a lot of animals.
All the way to the animal laboratory, passing through the layers of passages, putting on all the "arms", and spraying alcohol to disinfect, Chu Hanbo asked the laboratory staff to drag his mice over.
There is an "operating room" in the animal laboratory, but it is very simple and you have to perform aseptic operations yourself.
It was a bit crude. Chu Hanbo explained: "Generally speaking, this kind of operating room is used to kill mice. It is still lacking when it is really used to remove tumors or treat tumors."
"Next time, I will find a more professional animal experiment center. The equipment there is more complete."
Zhou Chenggong looked at the equipment around him, and then said: "Brother Chu, it seems that the only equipment that can be used here is the syringe. Although it is a bit violent, it is enough."
"What I need are cases of intraosseous tumors, not mice with subcutaneous tumors. Because mice with subcutaneous tumors are too simple to operate. Are they all in this batch?"
Zhou Cheng pointed to the cage, where some mice were running around, seemingly fine, but in fact they were eroded by tumor cells, and death was inevitable sooner or later.
"Of course, we made the appropriate choices before you came here. Tumors under the skin are cut open. If osteosarcomas are this long, then they won't be as scary as they are now."
Passing by Zhou Cheng's unintentional Versailles, Chu Hanbo nodded: "But, there is a problem now. There is no MRI or CT imaging equipment, only simple X-ray photos, and?"
Chu Hanbo looked at other tools and said: "There is no catheter for vascular blockade, so the operation is indeed much more difficult."
Zhou Cheng didn't answer. After washing his hands as usual, he put on gloves again. Then he caught one of the mice that was labeled and numbered, and asked someone to find its corresponding radiograph.
The location of the osteosarcoma was roughly determined.
When Zhou Cheng simulated basic anatomy theory, he did not simply simulate humans. Instead, he started with mice, then moved to pigs, cows, and finally humans.
The anatomy knowledge related to animals belongs to the content of veterinary medicine. Therefore, Zhou Cheng is actually involved in this aspect.
Zhou Cheng opened his mouth and said slowly: "The body length of this mouse is about 6cm, the tail length is 8cm, and the size is medium, and the weight should be about 154g!"
"For a mouse of this weight, the weight ratio of its limbs is..."
"Based on the body length and tail length, you can roughly calculate the length of the limb bone joints. It may not be accurate, but there is a range..."
"If variation factors are not taken into account, the diameter of the blood vessels should be proportional to the diameter of the bone to a certain extent."
"Teacher Luo, let me see what the scale of this X-ray is?"
Looking over, Luo Yundu was immediately stunned by these words.
Needless to say, Chu Hanbo and the others glanced at Zhou Cheng a few times, then looked at each other, with confusion visible in their respective faces.
How can TM still play like this?
An expert will know if there is one as soon as he takes action.
I don’t know if it’s true, but it’s quite professional and sounds very high-level...
Zhou Chengcheng was very satisfied with everyone's reaction, including Luo Yun!
Just kidding, can something that can hit the Nobel Prize be average?
Can an ordinary Versailles bear the title of Cai Dongfan's great disciple and successor of Fanxue?
Luo Yun was unmoved, and Zhou Cheng moved on his own: "The affected limb of the mouse is the left lower limb. From the current plain film, the diameter of 1/3 of the tibia of the mouse leg is about 1.2mm."
"The ratio of the diameter of the popliteal artery to the middle 1/3 of the tibia is probably between one-seventh and one-ninth, so it is tentatively determined to be 0.14mm!"
"The minimum diameter of our commonly used syringes is 0.55mm. With such a diameter, it is actually impossible to perform vascular block." Zhou Cheng analyzed it and got such a somewhat painful result.
Luo Yun and others looked at each other.
Well, they didn't consider this before, and it was indeed their mistake. Who would calculate these things?
However, it seems that Zhou Cheng would do such a thing.
"but!"
"In fact, we now have a needle for insulin injection, with a diameter of only 0.18mm, which can be used for this kind of operation."
"When I came over, I happened to buy a box." Zhou Cheng twisted his butt and motioned to put it in his trouser pocket, asking Luo Yun to help him take it out.
Luo Yun took a deep breath and said, "When did you buy it? Why didn't I know?"
Are you too stupid? You don't even discuss such an important matter with me?
Zhou Chengze is a little aggrieved. It's not what you said. Do you want to show it a little? If I had discussed it with you in advance, wouldn't it have lost its authenticity? These people are not stupid.
"Teacher Luo, I bought it when I went down to have breakfast this morning."
"Thank you for taking it."
Luo Yun immediately took out the so-called needle like a tool man. This kind of needle actually requires a prescription before it can be purchased.
However, insulin injections are routine supplies. Zhou Cheng also found a way to reveal his identity as a doctor and said that he was buying it for his family members and wrote the medical orders on the spot!
After everything is ready, the needle is replaced.
Zhou Cheng's sexy operation started again: "Based on the mouse model built in the past, to find the popliteal artery and popliteal artery of the mouse, our reference position is still the popliteal fossa, but the structure of the mouse is quite special..."
"We will probably insert the needle from here, which is exactly where the deviated popliteal artery is. If you feel it carefully, you can also feel some blood vessel pulsation."
"Oh, before we insert the needle, we need to paralyze the lower limb here."
"So, let's first perform a femoral nerve block anesthesia on the mouse!"
The mouse was not paralyzed yet, but the person was numb first: "Xiao, the femoral nerve block paralysis of the mouse? Why not directly anesthetize it locally?"
Who operated on the mice and administered nerve block anesthesia?
When a patient undergoes surgery, there may not be an anesthesiologist willing to provide this kind of anesthesia...
However, Zhou Cheng came here today just to show off his skills, and he showed off his skills on Mouse without any psychological pressure or guilt. At most, he could just say thank you, Teacher Mouse.
"After local anesthesia, local capillaries will be punctured, and the blood vessels will shrink relatively to stop bleeding, which will affect our operation."
"A nerve block, starting from the femur, would be more appropriate."
Chu Hanbo and Han Xiaoming were relatively calm and slowly watched Zhou Cheng's performance.
After Zhou Cheng completed the nerve block, one leg of the mouse was immediately paralyzed.
Zhou Cheng added: "Now, the muscles of the mice have relaxed, but the driving force for the beating of the blood vessels comes from the heart, so the fluctuations of the blood vessels are clearer. You can feel it."
The direction immediately reached out doubtfully.
Zhou Cheng slapped his hand in the direction and said, "Disinfect with alcohol!"
Xiang Xiang immediately withdrew his hand with a slight grievance. Han Xiaoming and Chu Hanbo, the corners of their mouths under the masks twitched slightly, glanced at Luo Yun complicatedly, and disinfected in a polite manner.
Then I checked and found that, as Zhou Cheng said, the pulsation was quite strong and it was actually not difficult to find.
This kind of feeling for blood vessel pulsation is a basic skill. It is a trick that is only used by interns and trainees to experience clinical practice. Zhou Cheng actually used this trick on them. Doesn't it mean that he and others can only experience it.
Nothing else can help?
But, hold on first!
Zhou Cheng then stopped trying to push away, and instead looked very nervous and serious: "There are two main blood sources for tumors in the middle part of the tibia."
"Periosteal arteries and nutrient arteries."
"The lateral periosteum is composed of the periosteal branches, musculoperiosteal branches and perforators of the anterior tibial artery, anterior tibial recurrent artery and posterior tibial artery. It surrounds the bone surface and is composed of forward external branches, descending branches and adjacent arteries. The periosteal arterial network
and the anterior border chain. The medial periosteum consists of the anterior tibial artery, anterior recurrent tibial artery, intermuscular branch of the infrapopliteal artery and posterior tibial artery, ascending laterally and medially, and the descending branch interconnects with the side branches of the descending branch of the tibial nutrient artery to form a periosteal arterial network.
and medial margin longitudinal chain.”
"We can't directly judge where the blood vessels originate from the mid-bone tumor, so we first block the entry end of the tumor-feeding artery..."
"Look everyone..."
Chu Hanbo really hates this saying, "Everyone is watching. What can I do if I don't watch?"
I thought to myself, but my body stood up on tiptoes honestly. As a result, I happened to actually see it. When Zhou Cheng was blocked, it seemed that there was blood flow in the middle part of the artery, causing the mouse's skin to bulge.
However, this does not prove that the tumor in the middle part of the tibia was killed.
After Zhou Cheng finished the operation, he continued: "This is the entrance to nourish the arterial network. In order to avoid arterial reflux and other situations, we also blocked the outlet. Without the supply of nutrients, there is no time to establish collateral circulation.
forward."
"The life time of osteosarcoma cells is actually quite limited." Zhou Cheng said, not knowing where he inserted the needle and completed the blocking operation.
Seeing everyone's confused eyes.
Then he said: "Oh, the artery I just blocked is..."
Luo Yun was annoyed by Zhou Cheng's ordinary attitude and patted him on the shoulder: "Be normal, talk about the key points, and stop pretending!"
