Sure enough, General Surgery has come up with something new.
Director Chi's guess is correct, the new thing is skin grafting technology.
He personally took Zhang Lin and Xiao Wu to see patients --- patients he personally selected.
There is a special smell emitting in the corridor of the burn department. This is the smell emitted by the patient's wound secretions when dressings are changed.
The wound dressing change in the burn department is the most difficult dressing change in all surgeries.
Especially for patients with large-scale burns, several doctors and nurses often cooperate, and it takes an hour or two to change the medicine.
Of course, the cost of dressing changes in the burn department is also the most expensive. A surgical dressing change in a general department can cost anywhere from a dozen to dozens of yuan.
The surgical dressing change in the burn department can easily cost several hundred yuan, or even more than a thousand yuan.
The patient is lying down and resting. Even when he is resting, he is wearing a mask and a hat. He does not want others to see that he is covered in scars.
The scars all over his body not only changed his appearance, but also caused many functional problems, such as scar contracture in the joints, which restricted the movement of almost all his joints. The scars all over his body caused his skin to lose its normal heat dissipation ability. Every summer,
, his risk of heat stroke is many times higher than that of others. Sometimes the scars will be painful and itchy.
The patient’s surname was Sun. He was only 30 years old. He was originally a middle school teacher. Once there was a fire in the dormitory of the senior high school students. A dozen classmates were trapped in the dormitory and could not get out. He went in and out of the fire several times to save the students, and the students were rescued.
He was severely burned.
At that time, the education department attached great importance to his injury and sent him to the best hospital in the local province. The burns were cured, but the remaining scars all over his body were not something the provincial hospital could do.
At that time, the director of the burn department also had the same opinion as Director Chi: If the scalp is intact, there is another way. The scalp can be cut repeatedly without forming scars. It is like cutting leeks, one after another. In this way, the scalp can be used as a
The supplier of skin grafting can solve most scar replacement problems after multiple surgeries.
But now Teacher Sun’s scalp is not healthy anywhere, it’s all scars.
The only skin that remains intact is the scalp. The skin in this area cannot be cut with leeks repeatedly like the scalp, so the use is limited and the doctor can’t find a solution for the time being.
A boss from Nandu Province invested in a business in Teacher Sun’s hometown. He was very moved when he heard about Teacher Sun’s deeds. So the boss contacted the school, hoping to help Teacher Sun cure his illness.
The boss heard that there was a fire hero whose arm was broken into five sections and was cured in Sanbo Hospital, so he took Teacher Sun to Sanbo Hospital.
Unexpectedly, the burn department of Sanbo Hospital was not strong and could not come up with any good plans. I suggested that Teacher Sun go to the First Affiliated Hospital of the Army or Air Force Medical University, or Changhai Hospital in Shanghai.
The boss who sponsored Teacher Sun immediately contacted Changhai Hospital in Shanghai through his personal connections. He was not sure about it and asked Teacher Sun to go take a look first.
Now Teacher Sun heard from Director Chi that there might be a solution at the General Surgery Department. Teacher Sun was very happy and willing to stay.
When the patient heard that the doctor for general surgery consultation had arrived, he felt a little embarrassed and took off his hat and mask.
Zhang Lin and Xiao Wu conducted a detailed physical examination on Teacher Sun and found that this patient was indeed covered in scars. Except for vaginal discharge, there was not a single piece of good skin on his entire body, and it was all covered with scars.
The auricle is contracted due to burn scars, resulting in very poor hearing.
Zhang Lin breathed a sigh of relief when he saw that Teacher Sun's skin was very intact, because Song Zimo's instructions to him were: As long as the patient has a piece of normal skin, even one square centimeter, then there is hope for the patient. p>
Skin in vitro amplification technology requires seeds, and a piece of intact skin is a seed.
"How's it going?"
Teacher Sun put on her clothes and asked worriedly.
Zhang Lin said with certainty: "It's stable!"
He has never seen Professor Yang conduct unreliable experiments on patients.

Faced with the induction formula on the A4 paper, Tang Shun thought about it for a long time.
If this induction formula is Yang Ping
The "hypothesis" is that it is impossible to succeed in one experiment. Even if you experiment many times, it is possible to eventually fail. Many projects end in failure.
To come up with such an induction formula, it is necessary to achieve Professor Yang's goal of expanding a piece of skin from 1 square centimeter to hundreds of square centimeters or even larger.
This kind of project cannot be completed by a top international team with good luck in less than three to five years.
Maninstein's team also spent three years to come up with the induction formula. This formula was purchased by Lanefei Company and continued research to achieve today's effect.
It is impossible for Professor Yang to obtain this induction formula, so it is very likely that he was inspired by Professor Maninstein and came up with this formula himself.
Moreover, the extraction of induction factors in this recipe seems too simple.

Zhang Lin and Xiao Wu signed a lot of documents for Teacher Sun, such as experimental informed consent, ethical informed consent, etc. Then they cut off a complete spindle-shaped piece of skin from the hospital, soaked it in protective solution, and sent it to the stem cell experiment.
room.
Several large culture vessels have also been filled with liquid formulated with induction factors.
This is not a small experiment, but a big topic that can touch the Nobel Prize.
Tang Shun didn't think that these few people could complete such an advanced subject, but out of admiration for Professor Yang, it didn't matter whether it worked or not, so just give it a try.
There are thousands of various factors in the human body. It is difficult to understand which ones are inducing factors and how they are combined. Otherwise, the development of stem cell technology would not have made breakthroughs.
Tang Shun can memorize this A4 paper.
If this kind of experiment were to be carried out at the University of Tokyo, it would require at least twenty-three PhDs and thirty-four master's degrees to start the experiment. The scientific research plan would have to be revised countless times before the start.
How could it be like this? A piece of A4 paper and a dozen amateur team members happily started the experiment.
I really can’t understand Professor Yang, the brain of a genius is just different.
"Hello Dr. Tang!"
Several masters and PhD students, some of whom walked into the laboratory with a bag of steamed buns.
While eating steamed buns, some people turned on the computer again and started working. This made Tang Shun very uncomfortable, but he didn't say anything. After all, they had just arrived. These people were also temporary scientific researchers. They just used their spare time to help. Their main occupation was surgery.
Doctor.
He didn't expect these amateur guys to achieve anything. Since Professor Yang trusted him so much, he was going to form a team of top talents.
Zhang Lin and Xiao Wu put a small piece of skin into a large incubator. The skin was soaked in the culture fluid, just like a small fish floating in a fish tank.
These induction factors were created by these young students using so-called new methods.
This scene is a bit like Tang Shun doing experiments when he was an undergraduate in China. In short, it feels a bit like children playing house.
