godfather of surgery

Chapter 680

Sure enough, General Surgery has come up with something new.

Director Chi's guess is also correct, the new thing is the skin grafting technology.

He personally took Zhang Lin and Xiao Wu to see patients --- patients he personally selected.

In the corridor of the burn department, there was a special smell, which was the smell from the patient's wound secretion when the dressing was changed.

Wound dressing change in the burn department is the most difficult dressing change in all surgeries, not one of them.

Especially for patients with extensive burns, several doctors and nurses often cooperate, and it takes one or two hours to change the medicine once.

Of course, the cost of dressing changes in the burn department is also the most expensive. A surgical dressing change in an ordinary department costs from a dozen to dozens of dollars.

The surgical dressing change in the burn department can easily cost several hundred yuan, or even over a thousand yuan.

The patient is lying down and resting. Even when he is resting, he wears a mask and a hat. He doesn't want others to see that he has scars all over his body.

The scars all over his body not only changed his appearance, but also brought many functional problems, such as scar contractures in the joints, which restricted the movement of almost all his joints. The scars all over his body made his skin lose its normal heat dissipation ability. , his risk of heat stroke is many times higher than others.Sometimes the scars are painful and itchy.

The patient's surname is Sun, only 30 years old. He used to be a middle school teacher. Once a fire broke out in the senior three dormitory of the school. More than a dozen students were trapped in the dormitory and could not get out. He went in and out of the fire several times to save the students. was badly 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 burn was cured, but the provincial hospital could not do anything about the scars left over his body.

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. This is like cutting leeks. The supplier of skin grafts can solve most of the scar replacement problems after multiple operations.

But Mr. Sun's scalp is not good now, it is full of scars.

The only intact skin is in the perineum. The skin in this area cannot be repeatedly cut with leeks like the scalp, so the use is limited, and the doctor can't find a way for a while.

A boss in Nandu Province invested in an enterprise 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 a firefighter hero had one arm broken into five sections and was cured in Sanbo Hospital, so he took Mr. Sun to Sanbo Hospital.

Unexpectedly, the burn department of Sanbo Hospital is not strong, and there is no good plan to come up with. I suggest that Mr. Sun go to the First Affiliated Hospital of the Army or Air Force Military Medical University, or Changhai Hospital in Shanghai.

The boss who sponsored Mr. Sun immediately contacted the Changhai Hospital in Shanghai through his contacts, but he was not sure there, so he asked Mr. Sun to take a look first.

Now Mr. Sun heard Director Chi say that there may be a solution in the general surgery department. Mr. Sun is very happy and willing to stay.

The patient heard that the general surgery consultation doctor had arrived, and took off his hat and mask a little embarrassedly.

Zhang Lin and Xiao Wu conducted a detailed physical examination on Mr. Sun, and found that this patient was indeed covered with scars all over his body. Except for the perineum, there was no good skin on the whole body, and the whole body was covered with scars.

The auricle is contracted due to burn scars, resulting in very poor hearing.

Zhang Lin was relieved to see that Mr. Sun's perineum skin was in good condition, because Song Zimo's instructions to him were: as long as the patient has a piece of normal skin, even if it is one square centimeter, then this patient also has hope.

In vitro skin amplification technology must have seeds, and a piece of intact skin is the seed.

"How about it?"

Teacher Sun put on his clothes and asked worriedly.

Zhang Lin said with certainty: "Stable!"

He has never seen Professor Yang do unreliable experiments with patients.
-
Facing the induction formula on the A4 paper, Tang Shun pondered for a long time.

If this induction formula is Yang Ping's "hypothesis", it is impossible to succeed in one experiment. Even if there are many experiments, it is possible to fail in the end. Many projects end in failure.

To come up with such an induction formula, to achieve Professor Yang's goal, a piece of skin of 1 square centimeter should be enlarged to hundreds of square centimeters, or even larger.

This kind of project, a top international team, is lucky, and it is impossible to complete it in less than three to five years.

It took Maninstein's team three years to come up with an inducing formula, which was purchased by Longer Ferry and continued research to achieve today's results.

It is impossible for Professor Yang to obtain this induction formula, so there is a high probability that he was inspired by Professor Maninstein and came up with this formula himself.

Moreover, the induction factor extraction on this recipe is too simple.
-
Zhang Lin and Xiao Wu signed a lot of documents for Teacher Sun, such as informed consent for experiments, informed consent for ethics, etc., and then cut off a piece of fusiform complete skin from the perineum, soaked it in protective solution, and sent it to the stem cell laboratory.

Several large incubators have also been filled with liquids configured with inducers.

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's not a big problem anyway, just give it a try.

There are tens of thousands of factors in the human body, which one is the inducing factor and how they are combined is difficult to understand, otherwise the development of stem cell technology has not achieved a breakthrough.

Tang Shun could memorize this A4 paper.

If this kind of experiment is to be carried out at the University of Tokyo, at least 23 PhDs and 34 masters will be organized to start the experiment. Before the start, the scientific research plan will have to be revised countless times.

How can it be like this, a piece of A4 paper, and then a dozen amateur team members started the experiment happily.

I really can't understand Professor Yang, the brains of geniuses are just different.

"Hello, Dr. Tang!"

Several masters and doctors, some with a bag of steamed buns, walked into the laboratory.

Some people turned on the computer and started working while eating steamed buns. This made Tang Shun very uncomfortable, but he didn't say anything. After all, they just came here. These people are also temporary scientific researchers. They just use their spare time to help out. Their main occupation is surgery. Doctors.

He didn't expect these amateurs to achieve anything. Since Professor Yang trusted him so much, he was going to build 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 solution, just like a small fish floating in a fish tank.

These inducing factors were created by these young students using so-called new methods.

Such a scene is a bit like Tang Shun doing experiments when he was an undergraduate student in China. In short, it is a bit like a child playing house.
