After the day's surgery, Yang Ping took a rest in the locker room.
As a surgeon, the dressing room is like a temporary harbor. Sitting quietly for a while can dispel the fatigue of the operation and reflect on the gains and losses of the operation.
For people with hobbies like Fatty, if they gather a few brothers with similar interests, hide in a certain place, smoke a soft Chinese, they will feel relaxed physically and mentally, as if they have become 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 smokers 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 took a week off, and Takahashi took a two-week short-term training. After mastering the technology of spinal external fixation, he has returned to Japan.
Phase II clinical trials of spinal external fixators at Xiehe, 301, Moliu and Nandu Affiliated Hospital have been launched. Phase III clinical trials in the United States, Europe and Japan are in full swing 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 certain 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 will be no possibility of subjective unwillingness to use new technologies anywhere, unless the local medical department
The technology is relatively backward, and doctors have not kept up with the pace of technological development.
Ruixing Company's production of spinal external fixators, including molds, processes, assembly lines, worker training, etc., has been completed and can be fully utilized for mass production at any time.
The new topic - stem cell cultured muscle, has been tested in the system laboratory Yang Ping, and some breakthroughs have been made. The actual laboratory is also fully prepared and has started to start.
"How are you preparing for the new topic?"
It took Yang Ping more than thirty hours to go to Germany. During this time, the preparations for the comprehensive surgical laboratory were changing every day.
In order to get Yang Ping's project started as soon as possible, Dean Xia and Director Han personally followed up and implemented the issues one by one.
Moreover, Dean Xia and Director Han did not let Yang Ping do too much work on these tasks, saying that they wanted Yang Ping to concentrate on academic work.
"Except for the cryo-electron microscope, which is borrowed from Nandu Medical University, all other equipment is already in place."
Song Zimo reported the latest progress.
Song Zimo was not only Yang Ping's assistant in clinical work, but also a powerful assistant in scientific research.
Now that Xu Zhiliang is sharing the work, the courage on Song Zimo's shoulders is much lighter.
"There is no rush for the cryo-EM, as long as it is useful, we will buy one in the future."
Yang Ping configures the equipment and instruments in the laboratory exactly according to the equipment of his own system laboratory.
Cryo-electron microscopy is an indispensable high-end instrument for structural biology. The new topic Yang Ping wants to conduct involves many structural biology studies, such as the structural analysis of induced proteins, which requires a cryo-electron microscope.
However, the cryo-EM requires a process from purchase, installation, debugging to application, at least several months. This is when purchasing does not require waiting for goods.
This thing is very expensive. 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. Currently, there are no corresponding products in the country, not even imitation products. They can only be imported from abroad at a huge cost.
Cryo-EM is expensive, ranging from 10 million to 100 million yuan. Currently, there are 27 cryo-EMs in China. The Southern University of Science and Technology in Pengcheng, Nandu Province, has a cryo-EM center and plans to install six cryo-EMs. Currently, it has
There are two units in operation. If all six units are installed, the Cryo-EM Center of Southern University of Science and Technology will be the third largest Cryo-EM center in the world.
If you borrow the cryo-electron microscope of Southern University of Science and Technology, you need to make an appointment, and it takes a lot of time to travel back and forth. You may need to wait more than ten days for one observation.
Fortunately, Nandu Medical University also has a cryo-electron microscope, and the laboratory there fully supports Yang Ping's research, giving priority to those in Yang Ping's research group, which can save time.
For the time being, he is borrowing the cryo-electron microscope from Nandu Medical University, and Yang Ping plans to buy one in the future. However, the project has just started and without any substantial progress, buying such a billion-dollar equipment will attract unnecessary criticism.
The big thing of cryo-electron microscopy has been settled, and the equipment for the entire project is now available, and the project can start to be carried out in reality.
However, in addition to having the equipment in place, a team also 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:
"Everyone, please pay attention. Are there any suitable talents in stem cell field who can be brought in to serve as the director of our laboratory? Or is it open to recruitment?"
Having a dedicated person in charge of the laboratory makes it much 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 could not find suitable candidates for a while. The more outstanding talents were either overseas and did not want to come back, or they were in top universities. How could they be willing to go to a hospital?
The laboratory platform is too small.
"Remember that Chinese translator when we were in Japan? Tang Shun!"
Song Zimo always remembered this person.
"Remember, what happened?" Yang Ping was deeply impressed by this man. He was also Gao Qiao's Chinese teacher.
Song Zimo said: "This person is engaged in stem cell research. His mentor at the University of Tokyo is from the Department of Stem Cell Biology, Institute of Frontier Medical Sciences, Kyoto University. Currently, in the field of stem cells, this Japanese professor is tied with a professor from the University of California, San Francisco.
World number one."
When Yang Ping heard that there was such a talent, he immediately said: "In this case, try to find a way to contact him. Can you introduce him?"
Song Zimo smiled and said: "I was just about to talk to you about this. Tang Shun is about to graduate with his PhD. 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 California Stem Cell Laboratory in the United States.
The laboratories of the University of San Francisco also offered him a postdoctoral position. These are the world's top laboratories, and the laboratories of our hospital. To be honest, the platform is small and pitiful."
This chapter is not over yet, please click on the next page to continue reading! Song Zimo is right. How could such a talent condescend to come to a small laboratory in a hospital.
However, when forming a team for a new project, it is necessary to have these biological talents, such as analyzing the structure of proteins. They are definitely more professional than Song Zimo and Xu Zhiliang. Only with the combination of different professional talents can the project be successfully completed.
"Not necessarily. It's best - Professor - you talk to him in person. If you see him right, there is still a chance."
Xu Zhiliang had been silent until he suddenly spoke.
Xiaowu introduced him to his girlfriend. At that time, Xu Zhiliang saw that the girl was very beautiful, had a good family background and a good job, so he thought he was totally out of luck. Unexpectedly, the two fell in love at first sight.
So some things are not necessarily certain! The key is whether you can meet your eyes.
Xu Zhiliang still has some say in this regard.
Hearing what Xu Zhiliang said, Song Zimo thought he should give it a try: "But things are not absolute. Although our laboratory is currently a hospital-level laboratory, the funds that can be mobilized are indeed something that ordinary laboratories dare not think of. This is
We will gradually improve our advantages and equipment."
"We will remember this person for now and try to contact him through Takahashi. I will find an opportunity to communicate with him face to face."
Yang Ping decided to give it a try and say no more if it didn’t work.
Anyway, meeting and chatting won't cause any harm.
When Jack Ma was sweating it out in a rental house by the West Lake, he also successfully tricked Boss Cai into forming a group.
My own laboratory still has advantages. It has abundant scientific research funds. Although it is a college-level laboratory now, it will soon become a national-level laboratory. These problems will not be a problem once results are achieved.
Moreover, in the future, Yang Ping will also purchase top-notch equipment such as cryo-electron microscopy. By then, scanning with cryo-electron microscopy will make his laboratory jealous.
The three of them chatted for a while, and Song Zimo suddenly remembered something else.
"I almost forgot that Xiao Guoqiang was having a review in the rehabilitation department this afternoon. I made an appointment with him to wait for me. Let's go and see it together?"
Song Zimo remembered that he had made an appointment with Xiao Guoqiang to see him in the rehabilitation department after the operation today, and he forgot about it while chatting.
Xiao Guoqiang is a fire hero Qiangzi. Yang Ping did a five-segment reimplantation case when he first came to Sanbo Hospital. He has been reviewed regularly in the rehabilitation department at Sanbo Hospital, and now he is reviewed every three months.
Yang Ping hadn't seen him for a long time and planned to go and see how he was recovering now.
The three of them had about the same amount of rest, changed 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 a primary school teacher, and now she has a slightly bulging belly. It seems that Qiangzi will soon be a father.
When Qiangzi was hospitalized, this beautiful elementary school teacher sent flowers to Qiangzi every day to express her admiration for the hero. Gradually, the two came together naturally. When Qiangzi got married, he even invited Dr. Corey and nurse to have a drink.
Wedding wine.
Qiangzi was very happy to see Yang Ping coming. He quickly shook hands and demonstrated the movement of his replanted limbs, which was quite satisfying.
"I just had surgery, so I kept you waiting for a long time." 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 examined him. Xiao Guoqiang's injured upper limb was shorter than the other limb. The functions of the elbow and wrist joints were completely normal. The function of the hand was relatively worse than normal, but the basic functions were restored very well.
.
The thumb can complete the palm-opposing function. This function is the most important to the hand function and is the core function. Many movements of the hand need to be based on the thumb-opposing function. The thumb function accounts for 40% of the entire hand and is realized through the palm-opposing movement.
of.
The flexion, extension, adduction and abduction of each finger of Hadron also recovered well, which shows that the flexors and extensors of the forearm have recovered well, and the thenar muscles, hypothenar muscles, interosseous muscles and lumbrical muscles of the hand have also recovered well.
Muscle recovery is good.
After checking the movement of his hand, Yang Ping checked the feeling of his fingers, especially the feeling of his fingertips. Although he was not as sensitive as normal fingers, he had recovered.
Through these examinations, it was shown that Xiao Guoqiang's three nerves: median nerve, ulnar nerve, and radial nerve had recovered well.
The most difficult thing to recover when replanting a severed limb is the nerve. If the nerve cannot be restored, the replanted limb will be a non-functional limb, meaningless and becoming a burden.
It is already very good for someone like Xiao Guoqiang to be able to return to his current level.
Not to mention multi-stage replantation, even simple replantation does not require complete recovery of functions. It is good to be qualified. Hadron is obviously far above the qualified line, and the basic functions of the upper limbs are completely preserved.
"I can use this hand to write, pick up things, and play with my mobile phone."
Xiao Guoqiang is very satisfied with his hand.
"Well, you're recovering very well. How's it going? Is your work going well now?"
Yang Ping finished the physical examination.
"I was transferred away from the front line and worked in the unit's logistics."
Qiangzi was a little disappointed with the transfer, but since he was so seriously injured, it was impossible to let him fight on the front line. He was not suitable physically and emotionally.
"How is the skin temperature of 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 on their hands due to insufficient blood supply, especially when the weather is cold. This is rare in the south, but more common in the north.
Therefore, the function of the replanted limb after surgery is reflected in many aspects, and it is not just about survival.
"Reexamination of the X-ray showed that the fracture was healed and reshaped well. I suggested that he take out the steel plate and needle later." Song Zimo had seen the X-ray of his re-examination.
Yang Ping also agreed: "Multi-segment fractures, if taken too early, can easily lead to re-fractures. It should be removed two years after the operation. The steel plates and needles left inside will not affect activities."
Generally, the plate for upper limb fractures is removed one year after surgery, but it may not be removed at all. The plate for lower limb fractures is generally removed two years after surgery. Except for special reasons in elderly patients, it must be removed.
Because the lower limbs have to bear weight, if the steel plate is not removed, the steel plate will transmit part of the stress instead of the human bones, causing the bones of the human lower limbs to become fragile and prone to fracture, while the upper limbs do not need to bear weight, so there is no such stress shielding phenomenon.
Xiao Guoqiang's upper limb steel plate is usually removed one year after surgery. However, considering the multiple fractures, it was extended for one year. Therefore, the standard time refers to the specific time of removing the steel plate and the fracture healing and shaping.
At present, Xiao Guoqiang has fully recovered and does not need to be reviewed again in the future.
After watching Xiao Guoqiang, Yang Ping was about to get off work, but received a call from Professor Zhang asking him to go to the orthopedic trauma department to see a patient.
This patient was a young man in his twenties with no history of trauma. He had necrosis of his limbs for unknown reasons. Limbs with severe necrosis may face amputation. The cause was not found after being hospitalized for several days.
Now we are temporarily organizing a hospital-wide consultation. We must first make a clear diagnosis and then 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.
