godfather of surgery

Chapter 354
Yang Ping was quite worried about little Andrew's operation.

Although detailed surgical drawings have been drawn, I'm afraid Robert still can't make satisfactory results of the operation.

With Robert's rigor as a doctor, he will definitely not do this operation rashly. He must either ask Yang Ping to do it, or wait a few years until Robert is proficient in the operation before doing it.

Robert should choose the former, because he is a doctor, an outstanding doctor, he will think from the patient's point of view, not his own interests.

The current difficult case in Yang Ping's hands, besides Little Andrew, is Boss Cheng's side. There is a patient with osteoarthritis of the knee joint. Yunjian failed the operation and plans to go to Liquan Hospital for renovation.

Wei Danian, who is admitted to the ICU once a year, has not yet been diagnosed. What is the cause of lactic acidosis?

The wechat group was specially designed to discuss Wei Danian's condition, and there was no news during this period of time. It seems that Dr. Wen of Nandu Medical University has not yet produced the results of the genetic test.

Yang Ping puts the most effort into it, and thinks Sisi is the most difficult. Sisi's femur has been extended by more than ten centimeters. Once it reaches the target value, the two ends will join forces. The next step is to rebuild her thigh muscles.

Multiple resections of the primary tumor were performed. At that time, not only the entire femur was resected, but also the surrounding muscles were resected. If the muscles were to be rebuilt, muscle flaps had to be taken from other places for transplantation.

The muscles of the thigh, whether it is the quadriceps or the biceps, are the strongest muscles in the human body and cannot find a suitable donor site.

This is a difficult problem, but these can be dealt with slowly. Sisi's last reexamination showed that no recurrence was found in the tumor treated with Haifu Knife.

But recurrence is a matter of time, and it is almost impossible to remove the spreading tumor cells by surgical means alone.

What if there is a relapse?
Continue to use Haifu Knife to deal with it. This kind of fire-fighting operation cannot touch the fire source, so it can only be exhausted.

But for osteosarcoma, there is no specific targeted drug in the world, and there is no good method except surgery, radiotherapy and chemotherapy. Relatively speaking, the focused ultrasound of Haifu Knife is already the best way.

For Sisi, Yang Ping had to think more long-term. Subconsciously, he had made up his mind to go all out, no matter what the outcome was, he would not hesitate.

Therefore, the laboratory rewarded by the system space is imminent for Yang Ping. He needs the laboratory to do research, just like massive surgical training. With this laboratory, he can establish research projects and spend infinite time on research. .

Yang Ping looked at the time on his mobile phone. Song Zimo's operation should have been in progress. He got up from the bench and went to the operating room to have a look.

The first operation was stress-free for Song Zimo, and the operation was performed strictly according to the standard procedure.

The steps of the standard process actually correspond to each scoring point, and the two are not contradictory.

Immediately afterwards, Director Han and Professor Zhang also came in. The two of them were discussing something.

Song Zimo's surgery is impeccable, every step is not redundant, not omitted, meticulous but not blunt, and there is no trace of deliberate regulation for the competition.

The judges who were watching the live broadcast scored the scores step by step, full marks, full marks, full marks——
Director Han and Professor Zhang seemed very relaxed. When they saw Yang Ping, Director Han waved: "Xiao Yang, the stem cell research license of the Institute of Orthopedics has come down. If you see any scientific research projects, you can establish one."

Now Yang Ping really wants to set up a project to do scientific research. For the time being, he wants to set the topic on the repair of defective tissue, such as the repair of muscle tissue defect. This is the problem that Sisi will solve in the next step.

It's too big a subject, we'll talk about it later when we get the system space laboratory.

"I want to set up a project in tissue engineering, which requires the use of stem cells and 3D printing." Yang Ping expressed his thoughts.

"The orthopedic laboratory is for your use, and all the equipment can be used at will." The purpose of Director Han to build this platform is for young people.

Yang Ping is already very familiar with the equipment inside. That 3D printer can print with Giant Vision, but not with Microvision, and even worse with nano-level ones.

This device originally had nanometer-level micro-vision printing, but when it was introduced, it was a restricted technology, and people were unwilling to sell it, and the corresponding hardware and software modules were castrated.

This is not surprising. Once these cutting-edge devices are introduced to China, these gringos will castrate their functions, intentionally reduce hardware and software modules, and discount the functions. They call it technical restrictions.

After Song Zimo's operation was completed, the video was turned off, and the scores already scored were all full marks.

This kind of operation is not difficult for any orthopedic surgeon to complete, but it is very difficult to achieve full marks.

Mr. Guo from the Department of Traumatology and Orthopedics went to the operating room one by one to inform him that he would treat him to dinner in the evening. Without knowing it, he thought that Mr. Guo was getting married or the child was full moon.

Mr. Guo is single, and he hasn't been promoted recently. What makes him so happy, broadcasting everywhere to invite people to dinner.

It turned out that Mr. Guo ended his one-year hospital life and ended his life of being on call 360 hours a day for 24 five days. Of course, it is worth celebrating.

He is going to set up a few tables near the hospital to celebrate. At the same time, he might as well inform everyone: those who have younger sisters, cousins, cousins, and other unmarried female relatives and friends can now officially introduce them to him.

If you don't eat this meal for nothing, everyone in the orthopedics department hears the news and yells to have a good get-together at night.

Seeing that Song Zimo had finished the first surgery for the Golden Knife Award, Director Han and Professor Zhang were fine and planned to leave. Director Han told Yang Ping to come up with the project as soon as possible, and he helped apply for funds.

Taking advantage of Yang Ping's free time, Takahashi came over and said, "Can we play tennis together after get off work in the afternoon?"

Yang Ping felt strange, he played tennis with baking soda, and played mandarin duck ball, what did you participate in.

Takahashi smiled and said, "It's not what I meant——"

Then he pointed to Fujiwara Miyuki who was chatting with Xiao Su and asking about equipment.

"It's her, Doctor Fujiwara, in the hospital gymnasium, she saw you playing tennis with Nurse Su several times, she asked me to tell you to play tennis together." Takahashi was just spreading the word, as for whether Yang Ping agreed, he could tell in spite of.

"She is a good tennis player!" Takahashi added.

Seeing that they are so interested, Yang Ping thinks it's okay to play together: "Okay, Mr. Guo of the Department of Traumatology and Orthopedics will treat you this afternoon. Let's have dinner together, and we'll go play after dinner."

After the operation for the Golden Knife Award, there are still a few operations to be performed by Song Zimo and Xu Zhiliang, and Yang Ping is also very free in the operating room.

He just wanted to communicate with Takahashi about tissue engineering, and what new research trends are there at the University of Tokyo.

After chatting for so long, Takahashi was still standing, and Yang Ping asked him to move a stool to sit down, so he moved a round stool to sit next to Yang Ping.

"In terms of tissue engineering, especially the application of stem cells in tissue engineering, what progress have you made?" Yang Ping asked Gao Qiao.

Takahashi is very familiar with these things, and he talked eloquently: "Duke University in the United States successfully cultivated muscles with stem cells for the first time, and the stem cell laboratory of the University of Tokyo followed closely, and soon after, they also cultivated muscles. These muscles have normal muscles. functions to receive stimuli and contract."

"They used pluripotent stem cells, injected a large amount of Pax7 protein into them, and used these proteins to release signals to the stem cells, and then directed the stem cells to differentiate into muscle cells. Under the nutrition support, these muscle cells can maintain stable division and development. On the prefabricated nano-7D template, after three to four weeks of culture, the muscle cells will gather to form muscle fibers, which are similar to normal muscle fibers of the human body. They can contract when stimulated, but the strength and strength are not as good as natural muscles. They transplanted the cultivated muscles into mice and obtained a three-week survival time. During the survival period, they had normal muscle functions."

"The Stem Cell Laboratory of the University of Tokyo, I am one of the main directors of this project. The key technology lies in the differentiation guidance of stem cells and the printing of nano-3D scaffolds. At present, our common obstacle is that the survival time of the cultivated muscle cells in experimental animals is relatively short. Short, our time can be extended to six weeks, twice that of the United States, but in the end muscle cells still disintegrate. If the mystery of disintegration can be solved, unlimited muscles can be cultivated in the laboratory in the future. On this basis, further Looking for differentiation-inducing substances for various tissues, so that the differentiation of any tissue is not a problem, unfortunately, at present, neither the United States nor we have only one differentiation substance-Pax7 protein."

Takahashi firmly believes in Yang Ping's ability, and he is very eager to establish cooperation with Yang Ping to carry out this project together, because he encountered resistance in this project and could not continue to break through.

I just learned from Director Han that the orthopedic laboratory equipment, 3D printers do not have the ability to print microscopically, this function was castrated by German manufacturers.

Because of these cutting-edge technologies, they need to keep them secret. At present, only the giant vision printing function is open. software modules.

To carry out this experiment, the 3D modular scaffolding for growing muscles is indispensable, which guides the arrangement of muscle cells.

"I want to set up this project at the Institute of Orthopedics, which also uses stem cells to cultivate muscle tissue. Regarding the problem of disintegration, the problem lies in the mitochondria, which is equivalent to the mechanism of cell aging and death, but it is an accelerated version of this mechanism. I set up this project , is to solve this problem, you and the Americans are at a dead end—”

In the system space, Yang Ping's knowledge obtained by using massive data is not comparable to Takahashi's in terms of breadth or depth.

It's just that Yang Ping hasn't conducted this kind of experiment so far. If he can cooperate with Takahashi, he can borrow the chicken to lay the egg, which will save a lot of time than starting over by himself.

Yang Ping pointed out the method of breaking the problem in one sentence, but stopped talking halfway through.

It is equivalent to patting your pocket, there is the sound of a key in it, but you just don't take out the key: "Here is the key!"

Takahashi has a deep understanding of Yang Ping's super high IQ, and he firmly believes that by cooperating with Yang Ping, he can find a way to break through.

But Yang Ping didn't propose cooperation, he just said plainly that Takahashi and the Americans had strayed into a puzzle.

"Dr. Yang, if you are interested, can we work together?" Takahashi tentatively asked.

Yang Ping seems to be not very interested: "My starting point is relatively high. If we cooperate, I don't want to do those basic things. I am only responsible for prolonging the survival period of the cultured muscle cells."

"Yes!" Takahashi was very happy, this is what they wanted, and they could never break through.
