godfather of surgery

Chapter 614
After one day's operation, Yang Ping took a rest in the locker room.

As a surgeon, the locker room is like a temporary haven. Sitting quietly for a while can dispel the fatigue of the operation and reflect on the gains and losses of the operation.

A person with hobbies like Fatty, with a few like-minded brothers, hiding in a certain place, smoking a soft Chinese, will feel relaxed physically and mentally, as refreshing as becoming a fairy.

Yang Ping, Song Zimo, and Xu Zhiliang wore hand-washing clothes, took off their hats and masks, and rested in a row on the bench. Robert followed the three bongs to the secret base to enjoy the soft "China". Several young doctors had already changed their clothes Send the patient back to the ward.

August was on leave for a week, and Takahashi was on short-term training for two weeks. After mastering the technique of spinal external fixation, he has returned to Japan.

The Phase II clinical trials of spinal external fixation systems for Xiehe, 301, Magic Six, and Nandu Fuyi have already started, and the Phase III clinical trials in the United States, Europe, and Japan are under intensive preparation and will be fully launched soon.

With the current situation, as long as the spinal external fixator technology does not collapse in clinical trials, it is a certainty that it will quickly enter the world.

Moreover, this technology has opened up a new field of spinal deformity treatment. It is a brand new technology, exclusive and non-substitutable. As long as it is fully rolled out, there is no possibility of subjective reluctance to use the new technology anywhere, unless the local medical The technology is relatively backward, and doctors have not kept up with the pace of technological development.

The production of spinal external fixators by Ruixing Company has been completed, from molds, processes, assembly lines, worker training, etc., and it can be mass-produced at full capacity at any time.

Yang Ping has started experimenting in the system laboratory for a new topic—stem cell cultivation of muscle, and has made some breakthroughs. The real laboratory is also fully prepared and started to start.

"How are you preparing for the new subject?"

It took Yang Ping more than 30 hours to go to Germany. During this time, the preparation of the comprehensive surgical laboratory was changing every day.

In order to get Yang Ping's project started as soon as possible, Director Xia and Director Han personally followed up and implemented each issue one by one.

Moreover, Dean Xia and Director Han didn't let Yang Ping work too much on these tasks, saying that it was for Yang Ping to concentrate on academics.

"Except for the cryo-electron microscope borrowed from Nandu Medical University, all other equipment is already in place."

Song Zimo reported the latest progress.

Song Zimo is Yang Ping's assistant not only in clinical work, but also in scientific research.

Now that Xu Zhiliang is sharing the work, Song Zimo's shoulders are much less courageous.

"There is no rush for a cryo-electron microscope, as long as it is useful, we will buy one in the future."

Yang Ping configures the equipment and instruments of the laboratory completely according to the equipment of his own system laboratory.

The cryo-electron microscope is an indispensable high-end instrument for structural biology. Yang Ping's new subject involves many researches on structural biology, such as the structure analysis of induced proteins, which requires a cryo-electron microscope.

However, from the purchase, installation, commissioning to application of the cryo-electron microscope, it takes a process, at least several months, and this is the case when the purchase does not need to wait for the goods.

This thing is very delicate, and a separate house needs to be built as a computer room, and the requirements for the computer room are very high.

This kind of high-end equipment is currently monopolized by the United States and Japan. At present, there are no corresponding products in China, not even imitation products. They can only be imported from abroad with huge sums of money.

Cryo-electron microscopes are expensive, ranging from 27 million yuan to [-] million yuan. At present, the number of cryo-electron microscopes in China is [-]. The Southern University of Science and Technology in Pengcheng, Nandu Province has a cryo-electron microscope center and plans to install six cryo-electron microscopes. There are two in operation, and if all six are installed, the cryo-electron microscope center of Southern University of Science and Technology will be the world's top three cryo-electron microscope centers.

If you borrow the cryo-electron microscope of Southern University of Science and Technology, you need to make an appointment to use it, and it takes a lot of time to run back and forth. It may take more than ten days to make an observation.

Fortunately, Nandu Medical University also has a cryo-electron microscope, and the laboratory over there fully supports Yang Ping's research project, giving priority to people in Yang Ping's research group to use, which can save time.

At present, I will borrow the cryo-electron microscope from Nandu Medical University for the time being, and Yang Ping plans to buy one in the future, but the project has just started, and without any real progress, buying this kind of [-] million yuan equipment will attract unnecessary criticism.

The cryo-electron microscope has been settled, and the equipment for the entire project is now ready, and the project can also be started in reality.

However, in addition to the equipment in place, a team needs to be formed. In addition to the doctors in the department, basic research talents in stem cells are also needed.

Yang Ping told Song Zimo and Xu Zhiliang:
"Let's pay attention to whether there are suitable stem cell talents introduced to serve as the director of our laboratory? Or open recruitment?"

There is a special person in charge of the laboratory, which makes it easier for everyone and the talent structure is more reasonable.

Yang Ping and Su Nanchen also mentioned this matter, and asked Lin Lan to help find talents in this field, but they couldn't find suitable candidates for a while, relatively good talents, either they were overseas and didn't want to come back, or they were in top universities, how could they be willing to go to a hospital In the laboratory, the platform is too small.

"Remember the Chinese translator when we were in Japan? Tang Shun!"

Song Zimo always remembered this person.

"Remember, what's the matter?" Yang Ping was very impressed with this man, and he was also Gaoqiao's Chinese teacher.

Song Zimo said: "This person is engaged in stem cell research. His supervisor at the University of Tokyo is from the Stem Cell Biology Department of the Institute of Frontier Medical Research, Kyoto University. Currently, in the field of stem cells, this Japanese professor and a professor at the University of California, San Francisco are ranked in the same rank. World number one."

When Yang Ping heard that there was such a talent, he immediately said: "In this case, find a way to get in touch with him, can you bring him in?"

Song Zimo said with a smile: "I was just about to talk to you about this. Tang Shun is about to graduate with a Ph.D. It may not be so easy to introduce this kind of talent. He has a wide range of choices. Not only the stem cell laboratory of the University of Tokyo wants to keep him, but also the stem cell laboratory in California, USA. The laboratories of the University of San Francisco also offered him a postdoctoral olive branch, these are the world's top laboratories, and the laboratories of our hospital, to be honest, have a pitifully small platform."

What Song Zimo said was right, how could such a talent condescend to come to a small laboratory in a hospital.

However, the formation of a team for a new project must have these biological talents, such as analyzing the structure of proteins. They are more professional than Song Zimo and Xu Zhiliang, and the combination of different professionals can successfully complete the project.

"Not necessarily, it's best—professor—you talk to him personally, if you see the right way, there is still a chance."

Xu Zhiliang didn't speak all the time, but suddenly spoke.

Xiao Wu introduced his girlfriend to him. At that time, Xu Zhiliang saw that the girl was very beautiful, and her family conditions and job were also good.

So some things, not necessarily!The key is whether you can meet your eyes.

Xu Zhiliang still has a say in this aspect.

Hearing what Xu Zhiliang said, Song Zimo felt that he should also try: "However, things are not absolute. Although our laboratory is currently a college-level laboratory, the funds that can be mobilized are indeed beyond the imagination of ordinary laboratories. Our advantages, and in terms of equipment, we will gradually improve."

"Let's keep this person in mind for the time being, and try to find a way to contact him through Takahashi. I'll find a chance to communicate with him face to face."

Yang Ping decided to give it a try, and let’s talk if it doesn’t work.

Anyway, meeting and chatting won't cause any harm.

When Ma Yun was sweating in the rental house by the West Lake, he also successfully tricked Boss Cai into forming a group.

My own laboratory still has advantages and strong scientific research funds. Although it is a college-level laboratory now, it will soon become a national-level laboratory in the future. These problems will not be a problem after they have results.

And in the future, Yang Ping will also buy top-level equipment like cryo-electron microscopes. At that time, if he wants to scan with a cryo-electron microscope, he will make his laboratory envious and jealous.

The three chatted for a while, and Song Zimo suddenly remembered something else.

"I almost forgot, Xiao Guoqiang is in the rehabilitation department for reexamination this afternoon. I asked him to wait for me. Let's go and have a look together?"

Song Zimo remembered that he had already made an appointment with Xiao Guoqiang, and went to the rehabilitation department to see him after the operation today, and even forgot while chatting.

Xiao Guoqiang is the hero of firefighting. Yang Ping did five-segment replantation cases when he first came to Sanbo Hospital. He has been in the rehabilitation department of Sanbo Hospital for regular review, and now he has a review every three months.

Yang Ping hadn't seen him for a long time, and planned to see how he was recovering now.

The three of them rested almost as well, changed their clothes and went to the rehabilitation department.

Qiangzi and his wife were waiting for Song Zimo in the rehabilitation room of the rehabilitation department. They must have been waiting for a long time.

His wife is an elementary school teacher, and now she has a slightly protruding belly. It seems that Qiangzi is going to be a father soon.

When Qiangzi was hospitalized, the beautiful primary school teacher gave Qiangzi flowers every day to express his admiration for the hero. Gradually, the two came together naturally. When Qiangzi got married, he also invited doctors and nurses to drink. wedding.

Seeing that Yang Ping also came, Qiangzi was very happy, shook hands quickly, and demonstrated his replanted limbs, quite satisfied.

"I just had surgery, so I kept you waiting." Song Zimo apologized.

Qiangzi was very happy: "I just chatted with the rehabilitation doctor, anyway, I'm not in a hurry, I know you are busy."

Yang Ping didn't waste time, and immediately gave him a physical examination. Xiao Guoqiang's injured upper limb was shortened compared with the other limb, and the functions of the elbow joint and wrist joint were completely normal. The function of the hand was relatively poor, but the basic functions recovered well. .

The thumb can complete the palm-opposing function. This function is the most important for the hand function, and it is the core function. Many movements of the hand need to be based on the thumb-palm-opposing.

The flexion and extension, adduction and abduction of each finger of Qiangzi also recovered well, which shows that the flexor and extensor muscles of the forearm have recovered well, and the internal muscles of the hand such as the thenar muscles, hypothenar muscles, interosseous muscles and lumbrical muscles have recovered well. Muscle recovery is good.

After checking the hand movement, Yang Ping checked the feeling of his fingers, especially the feeling of the finger pulp. Although it was not as sensitive as normal fingers, they all recovered.

Through these examinations, it shows that Xiao Guoqiang's three nerves: the median nerve, ulnar nerve, and radial nerve have recovered well.

The most difficult thing to restore in replantation of a severed limb is the nerve. If the nerve cannot be restored, the replanted limb will be a non-functional limb, meaningless, and will become a burden instead.

It is already very good for someone like Xiao Guoqiang to be able to return to his current level.

Not to mention multi-segment replantation, even simple replantation, we can't demand complete recovery of functions, it is good to be qualified, Qiangzi is obviously far above the qualified line, and the basic functions of the upper limbs are completely preserved.

"I can write, hold things, and play with my phone with this hand."

Xiao Guoqiang is very satisfied with his hand.

"Well, the recovery is very good, how is it, is the work going smoothly now?"

Yang Ping finished his physical examination.

"I was transferred from the front line to work in the logistics of the unit."

Qiangzi was a little disappointed with Tiaoli, but he was injured so badly, it was impossible for him to fight on the front line, it was not suitable physically or emotionally.

"How's the skin temperature on your hands?"

Yang Ping asked Song Zimo.

"There is no obvious difference from the healthy side." Song Zimo checked the blood supply of the limbs.

Some replanted limbs are prone to frostbite due to insufficient blood supply, especially when the weather is cold. This situation is rare in the south, but more prominent in the north.

Therefore, the function of the replanted limb is reflected in many aspects, not just survival.

"Re-examination of the X-ray shows that the fracture is also healed and shaped well. I suggest that he get the steel needle later." Song Zimo has seen his re-examination X-ray.

Yang Ping also agreed: "Multi-segment fractures, if obtained too early, may lead to re-fractures, it should be removed two years after the operation. The steel plates and needles left in them will not affect the activities."

Generally, the plate for upper extremity fractures is taken one year after surgery, or it may not be taken all the time; the plate for lower limb fractures is generally taken two years after surgery, except for special reasons for elderly patients, it must be taken.

Because the lower limbs have to bear weight, if the steel plate is not removed, the steel plate will replace the human bones to conduct part of the stress, resulting in the bones of the lower limbs becoming fragile and prone to fractures, while the upper limbs do not need to bear weight, so there is no such stress shielding phenomenon.

Xiao Guoqiang’s upper limb plate is usually taken one year after surgery. However, due to multiple fractures, the plate is taken one year later. Therefore, the standard time refers to the specific time of plate removal and the fracture healing and shaping.

At present, Xiao Guoqiang is considered to have fully recovered, and there is no need for reexamination in the future.

After watching Xiao Guoqiang, Yang Ping was about to leave work, and then received a call from Professor Zhang, asking him to go to the Trauma Orthopedics Department to see a patient.

This patient is a young man in his 20s with no history of trauma. Unexplained necrosis of limbs occurred. Severe necrosis may face amputation. He was hospitalized for several days without finding the cause.

Now temporarily organize a hospital-wide consultation, first of all to make a clear diagnosis, and then to find an effective treatment plan.

After the patient is admitted to the hospital, if the diagnosis cannot be made clearly within three days, attention must be paid and discussions must be carried out within a certain range.
