Doctor’s Life Simulator

The three chatted for a while, and then Qian Dongyu asked:

"Yiyi, how is your dissertation topic? I didn't ask you to change it last time. Is there a new direction?"

Director Ling Zhongyu closed his eyes and calmed down, and did not speak, but his ears were listening, and Qiao Yiyi answered.

In fact, this student of mine is very individual and persistent. Last time, he proposed a research direction: the exploration of the preservation method of allogeneic tendons.

So far, the conventional preservation method is cryogenic freezing, which is complicated and time-consuming, and the preserved tendon has low activity, which limits its application.

It is not that no one has thought about improving the preservation method, but no optimal solution has been proposed. Therefore, the transplantation of allogeneic tendon has not been widely promoted due to this limitation.

As a graduate student, Qiao Yiyi is too difficult to explore such a topic, and there is no guarantee that the results will be produced in the short term. For her current stage, it is not a good topic.

Therefore, Deputy Director Qian Dongyu has been persuading her to give up this topic that seems to have great potential but has little hope in reality.

Hearing Deputy Director Qian Dongyu's question, Qiao Yiyi obviously didn't want to answer too much, because she still wanted to give it a try. She always felt that there was a good way to solve this problem.

There was even a hint of expectation in her heart, whether it was possible to get some inspiration from the Hecheng treatment center.

Seeing that Qiao Yiyi remained silent, Deputy Director Qian Dongyu shook his head helplessly:

"Since you still don't give up, I'll give you another period of time. However, after a month, if you still can't produce results, you must stop. We will set a new direction for you to open the question. Yiyi, I and Director Ling It is impossible for you to find a suitable preservation method so easily in a short period of time.”

Qian Dongyu also thought of when he was young, he always felt pretentious and could become a star doctor who solves problems in the industry, but after constant trial and error, he understood that most people are ordinary.

The preservation method of this allogeneic tendon that Xiang Qiao Yiyi chose was such an almost impossible task. Moreover, in such a rare field, there are no experts studying it, so there are too few industry experiences that can be referenced. Undoubtedly, it added a lot of difficulty.

"I really don't want to die until the Yellow River."

Director Ling Zhongyu closed his eyes and sighed in his heart, because this student of his own was looking for something, and he was too stubborn. It is an advantage and a disadvantage, and it is easy to go all the way to the dark.

The three of them stopped talking about the topic, but talked about the trip to the treatment center.

Deputy Director Qian Dongyu drove the car and saw that Navigator was about to arrive at the First City Hospital. It was more than an hour earlier than the time agreed with Director Wei, and he suggested:

"Director Ling, why don't we contact Director Wei with a big fanfare to greet him, and let's take a quiet tour first to see what the treatment center looks like on weekdays."

Ling Zhongyu also felt good about this suggestion. After all, he participated in the characteristic subject of the treatment center before, and the most important thing was that he liked Qin Lang.

He also wanted to know how the treatment center normally operates, and whether it was worth their diligent cooperation and preparation for today's exchange topic.

Qiao Yiyi's eyes also flashed, and she was going to go to the laboratory of the treatment center to see if there was any research on allogeneic tendons, or if she was a fellow.

In fact, Director Ling and Deputy Director Qian are always throwing cold water on her, she needs some support and a life-saving straw!

"This is the subject that I am most interested in and want to complete. I don't want to end it before it starts."

Soon, the three of them quietly drove the car to the burn and plastic surgery building.

Ling Zhongyu brought the team members to the treatment center. Compared with the last time, Director Ling came to visit and improved a lot.

"Well, let's go directly to the operating room of the treatment center to see their usual level of surgery."

Ling Zhongyu and Head Nurse Zhao Qiufang were already very skilled, so they greeted Zhao Qiufang and signaled not to disturb Director Wei and the rest of the doctors, so they went to the operating room to observe.

And Qiao Yiyi was still a graduate student, so he didn't have much interest in this kind of surgery, so he applied with Director Ling to visit the laboratory of the treatment center.

Ling Zhongyu naturally knew about her student, but she didn't give up, but she didn't force it, so she let her hit the wall.

This kind of topic, even the hand surgery department of the Ninth People's Hospital Affiliated to Modu Jiaotong University, how could the treatment center of the city's first hospital be able to inspire her: "Then you can go and visit."

Originally, today is the expert exchange day, and it is a very reasonable thing to learn from each other.

...

...

While Ling Zhongyu and the others were splitting up, in the operating room of the treatment center, three operations by Qin Fa were still arranged this morning.

In the past week, Yang Yi and Yang Yue have basically mastered all of Qin Fa's operations, so this operation is their first show without Qin Lang's check.

In addition to Deputy Director Huang Kaihang in the outpatient clinic, You Daren and Peng Yun.

And Cheng Yunfeng, who is very discerning, with three small benches, is here.

Cheng Yunfeng is very sensible, and he gave You Daren and Peng Yun the bench.

Then he came to the corner and sat in a row with the anesthesiologist.

When Ling Zhongyu brought Qian Dongyu into the operating room, he was obviously stunned by the battle in front of him.

"Where is the expert from here giving a demonstration?"

Ling Zhongyu blinked, looking at the operating room, everyone was watching quietly, even if he was embarrassed to disturb him, he took Qian Dongyu to the edge.

As for Ling Zhongyu and Qian Dongyu coming in to observe, You Daren, Peng Yun and others are also used to it. After all, these days, there are too many doctors who have come to observe Qin Lang, Qin Fa.

Director Tian Hua came to watch every now and then.

Sitting on the bench, they also felt that it was too far-sighted for Qin Lang to put Cheng Yunfeng in the Qin Fa study team. He was the best logistics captain. Not only did they sit on the bench, they also wore pig trotters every day in the duty room. Snacks, men with fruit, women with milk tea.

As for the two newcomers, Cheng Yunfeng also observed them and didn't know each other.

Where did the wild doctor come from?

Cheng Yunfeng frowned slightly. According to his observation, whenever Qin Lang was the chief swordsman, Director Tian Hua would appear on time. As soon as Qin Lang was over, he also quietly left.

Therefore, Cheng Yunfeng has already prepared. When Qin Lang is the chief knife, he will prepare an extra small bench, and Director Tian Hua's flattery will also be well done.

As for these two new arrivals, what are the routes and whether they need good service or not, it remains to be seen.

On the operating table, Yang Yi and Yang Yue have already started the first step of tendon repair.

Ling Zhongyu and Qian Dongyu saw at a glance that this was a very conventional repair operation for hand avulsion injuries.

"Why, so many people come to observe and study for an avulsion injury surgery?"

Ling Zhongyu and Qian Dongyu both observed in confusion.

"Huh? What suturing method is this?"

Even if he was well-informed, Ling Zhongyu was a little confused for a while. According to his common sense, the best way to repair the tendon here should be to improve the Kessler method. What stitches are they using?

Deputy Director Qian Dongyu also didn't quite understand, and even thought, isn't this nonsense.

In fact, Yang Yi is not Qin Lang. Although she has mastered the half-knot locking tendon suture method, the level of suture is alright in front of Ling Zhongyu and Qian Dongyu.

Therefore, they did not feel the extraordinary and uniqueness of this stitching method.

However, after all, the two of them came from afar to observe and study. They were very patient and wanted to see what kind of trick Yang Yi was going to make.

Soon, Yang Yi completed the suture repair of the tendon, which was much slower than the conventional modified Kessler method.

Qian Dongyu looked a little distracted. After all, with his speed, how could the repair of this tendon be so slow. With this messy stitching method and slow movements, Qian Dongyu suddenly had a thought in his heart, whether he had overestimated the level of the treatment center.

The pentagon-shaped skin flap modified by Qin Lang must be just a temporary fix. After all, the level of this treatment center is too poor. It is such a slow operation and a group of doctors are required to observe and learn.

...

...

at the same time.

In the laboratory of the treatment center, Qin Lang was personally preparing the amniotic membrane for Yang Yi and Yang Yue.

The amniotic membrane was bluntly separated from the placenta under sterile conditions, and then washed repeatedly with PBS liquid, and then placed in dpbs solution supplemented with penicillin-streptomycin and amphotericin b for immersion and washing.

Then, on the ultra-clean bench, the amniotic membrane was flattened on the sterile pvdf membrane, cut into a size of 3cm × 3cm, put into a petri dish and added with dmem medium (dmem + penicillin + amphotericin b + glycerol), and then It is stored in a -80°C refrigerator for later use.

It is true that there are too many patients with the Qin method recently, so Qin Lang needs to prepare a lot of amniotic membranes in advance.

While preparing the amniotic membrane, Qin Lang also thought of the vitrification method of the allogeneic tendon that he had recently obtained.

The cryogenic freezing method commonly used in clinical practice is complicated and time-consuming, and the preserved tendon has low activity. The preservation method obtained by Qin Lang is a brand-new method. made of the recipe.

After that, the high-concentration solution is rapidly cooled in a single step, so that the tissue and solution directly enter the glass state, and no ice crystals are formed during the freezing process, which avoids conventional ice damage and freeze-thaw effects, and effectively preserves cell activity.

This is a completely new method of preservation of allogeneic tendons.

Qin Lang was also thinking about planning to find a suitable time to find a candidate in the treatment center to arrange the experiment of this preservation method and the presentation of the results of the thesis later.

With this new preservation base fluid and vitrification method, a whole new field of allograft tendon transplantation can be performed in treatment centers, which will be a whole new world, especially for patients with long distance and multiple tendon defects Treatment.

The potential of this brand-new subject is no less than the "Qin method", and Qin Lang plans to gradually extend it to the later, vitrification method to cryopreserve cells (descendant cells, embryos, embryonic stem cells, etc.), and can be promoted Clinically, skin, cornea, nerves, blood vessels, heart valves, cartilage, kidneys, etc.

Of course, each different target, the base fluid required, needs to be tested.

Right now, when Qin Lang was about to roll up his sleeves again and have a big fight.

[Ding, UU reading www.uukanshu.com host's talent: Peach Blossom activates! 】

When Qin Lang heard this inexplicable system prompt sound, his head was naturally a little big, and then he heard a timid and expectant voice outside the laboratory:

"Hello, brother, can I come in and visit?"

Qin Lang turned his head and looked over, only to see Qiao Yiyi, who was 1.7 meters tall, thin and white, and had the same appearance as Tang Yue.

The girl was a little shy with a white and slender hand pushing her black-rimmed glasses, and also looked at Qin Lang, who turned her head, somewhat surprised and handsome.

Seeing Qin Lang turn his head, Qiao Yiyi added:

"I'm a doctor of hand surgery at the Ninth People's Hospital Affiliated to Modu Jiaotong University, who came to the city's first hospital with Director Ling for an expert exchange day. My name is Qiao Yiyi."

"Senior brother, hello!"
