Doctor: I picked up attributes in the hospital

Chapter 423 Autologous Tumor Bone Inactivation Replantation and Heavy Ion Proton Therapy
The next day.

Eight twenty in the morning.

In the office, Zhao Heng was having a morning meeting.

After Li Yang, the doctor in charge of the night shift, explained the situation of the night shift, Zhao Heng looked at the doctors present and said slowly, "What do you think about the treatment of the newly admitted Ewing's sarcoma patient yesterday?"

As soon as Zhao Heng said this, all the trainees, trainees, and interns present fell silent. The treatment of a patient with advanced Ewing's sarcoma is obviously not what they can handle at the current level.

Seeing that everyone was silent, Zhao Heng felt a little disappointed. It is obviously not so easy to cultivate capable officers. Look at the current dean Liu Shangming. He has been the director of the oncology department for so many years. Li Haiyang?
If Zhao Heng wants to cultivate the main force of the department at Li Haiyang's level, it obviously needs a long distance, and this distance is not easy to narrow.

After a while, Liu Meng said: "For now, it is to implement the radiotherapy and chemotherapy plan determined by the oncologist and strengthen nursing care. I suggest some treatments that can help improve physical fitness."

"That's it, the meeting is over."

Zhao Heng nodded and didn't say anything else. What Liu Meng said was just the conventional way of treating patients with advanced tumors. After all, most doctors in most hospitals treat them in this way.

It’s just this effect, which is hard to say, as can be seen from the terrible low survival rate of advanced Ewing’s tumor.

After the meeting was over, Zhao Heng took Liu Meng and a bunch of trainees, trainees, and interns to round the ward together.

To be honest, these advanced training, training and interns have also been in the department for several days, but apart from Ruan Liuzheng, no one has left a deep impression on Zhao Heng, let alone Zhao Hengsheng. It feels like teaching yourself.

I have to say, talent is rare!

After a while, Zhao Heng brought several doctors to the ward of Wu Yiming, a little girl suffering from Ewing's sarcoma.

Entering the ward, Zhao Heng saw Wu Yiming lying on the hospital bed, his face was pale, and he didn't have the vigor and vitality of a seventeen or eighteen-year-old girl at all.

Seeing Zhao Heng coming in, Father Wu, who was sitting by the hospital bed, quickly stood up.

"Director Zhao."

Father Wu said.

To be honest, before bringing his daughter here, he was somewhat expectant, hoping to create a miracle with Zhao Heng.

But the reality is cruel, but thinking about it, Youhao Hospital, as the top cancer hospital in China, has no good way to do it. It can only do radiotherapy and chemotherapy. Amputation.

It is similar to other hospitals in the country.

"Director Zhao, besides radiotherapy and chemotherapy, is there really no other treatment?"

After a pause, Father Wu asked again with some unwillingness to give up.

Regarding the therapeutic effects and side effects of radiotherapy and chemotherapy, the doctors there have already made it very clear when I was in Youhao Hospital. The mainstream treatment method is used by most cancer hospitals.

"Chemotherapy and radiotherapy are currently the mainstream treatment methods for Ewing's tumor. Currently, there is another treatment method."

Zhao Heng thought for a while and said, he was sitting on the sofa playing with his laptop for half a day last night, and he was just trying to find a treatment method for Ewing's tumor other than radiotherapy and chemotherapy. This method is not common. At present, it is rarely used. .

"What kind of treatment? Director Zhao, you said, as long as there is a glimmer of hope, we are willing to try."

Father Wu heard what Zhao Heng said, and hurriedly continued.

During this period of time, he also consulted many oncologists through some channels. After consulting more, he gradually understood that for his daughter's current disease, radiotherapy and chemotherapy are simply to prolong a certain life in pain. , is almost meaningless in the long run.

Compared with painful treatment that can only prolong a short life, it is better to let the quality of the remaining life be higher.

"Currently, for the treatment of Ewing's osteosarcoma, there is another method, which is autologous tumor bone inactivation and replantation."

Zhao Heng said briefly.

As soon as he said this, not to mention Wu's father, even several advanced trainees, regular trainees, and interns, and even Liu Meng, all looked at a loss.

Obviously, everyone has never heard of the treatment method mentioned by Zhao Heng.

"Autologous tumor bone inactivation and replantation is to physically and chemically inactivate the residual autologous bone after removing the tumor tissue, and then transplant it back into the human body in situ."

After a pause, Zhao Heng explained.

"Director Zhao, can you explain in more detail? I don't understand."

Father Wu said.

"To put it simply, it is to take out the bone with tumor, kill the tumor cells, and then transplant the bone back to let the bone start to grow again. The advantage of this is that there is no need for amputation, but it is currently a trial in China. At this stage, there are no reports on the success rate."

Zhao Heng explained patiently.

When he said this, Liu Meng seemed to recall that there was this kind of treatment method, but several advanced training, regular training and intern doctors still looked at a loss. Obviously, with their level and knowledge, they did not listen. Having said that about this rare treatment.

"Here, this bone has been taken out for disposal, can it still live again if it is put back?"

Wu's father said with some doubts and anxiety when he heard the words.

"Generally speaking, there are liquid nitrogen, hypertonic saline and microwave methods for extinguishing isolated tumor bone cells, but these methods will cause great damage to the remaining normal bone cells."

"The medical department of Yenching University has newly purchased a heavy ion proton instrument, which can be used to kill tumor cells at a fixed point. If these two treatment methods are combined, the normal residual bone transplanted back will survive. The probability will be relatively high. Of course, no one can guarantee [-]% success of such an experimental treatment."

Zhao Heng explained.

As soon as these words came out, heavy ions and protons, not to mention Wu's father, even a few advanced students, regular trainees and interns were dumbfounded.

"Director Zhao, can I trouble you to explain again?"

Father Wu continued, as expected of the chief director, the method he used was not mentioned by the oncologist he had seen before.

This made Wu's father rekindle some hope in his heart.

"Heavy ions and protons both belong to particle beams. Different from traditional photon beams, particle beams can form energy Bragg peaks, which can blast tumors intensively and reduce damage to healthy tissue cells."

"To put it simply, the extermination of tumor treatment in the past is equivalent to bombing one by one with a bomber, and the heavy ions and protons are equivalent to the precise attack of a fixed-point cruise missile."

Zhao Heng tried his best to explain in a simple way.

When protons or carbon ions are accelerated to about 70% of the speed of light by a synchrotron, these ion rays are drawn out and injected into the human body. Before reaching the tumor lesion, the energy of the ray is not released much, but after reaching the lesion, the ray will instantly release a large amount of energy, forming The energy release trajectory named "Bragg peak", the whole treatment process is like "stereotactic blasting" for tumors, which can kill tumor cells to the greatest extent while reducing damage to normal tissues.

"Director Zhao, can this treatment really avoid amputation?"

Father Wu couldn't help asking.

He knew that amputation was the most unacceptable thing for his daughter.

"This method does not require amputation, but since it is still in the experimental stage, it is hard to say whether it will be successful."

Zhao Heng nodded.

"Dad, I'm going to do this treatment."

Before Wu's father opened his mouth, the little girl Wu Yiming said firmly that amputation is too cruel for a little girl of the same age, especially a top national skier.

It can be said that she would rather die than amputate!
"Director Zhao, please, no matter how successful it is, we are willing to give it a try."

Hearing his daughter's words, Father Wu immediately made up his mind. His daughter didn't want amputation, so why would he want to see his daughter's leg amputated.

"It will take some time to prepare for the surgery. During this time, it's best to calm down and take care of your body as much as possible."

Zhao Heng said.

"Okay, we got it, Director Zhao."

Father Wu nodded. Obviously, Father Wu had seen the world. He knew that at such a time, he could only try his best. At least, when other oncologists had no choice, Zhao Heng proposed a A new method of treatment.

It is good to have hope, and Father Wu can only think so now.

At this moment, the trainees, regular trainees, and interns standing behind looked at Zhao Heng with admiration.

If these new young doctors had doubts about the same young Zhao Heng in the past, this doubt has been completely dispelled now.

They had never heard of Zhao Heng's combination of two treatment methods.

Out of the ward, Liu Meng, who was following Zhao Heng, suddenly said worriedly: "Director, it's not easy to borrow the heavy ion proton therapy device from Yenching University. There was a patient in the oncology department before, and he wanted to go to the hospital. Try this treatment, it has never been ranked."

"It's okay, I still have some contacts at Yenching University."

Zhao Heng said.

"That's right, it's Professor Li Hongwei, I even forgot about that."

Liu Meng just remembered that Zhao Heng and Professor Li Hongwei developed siRNA colloidal bundles together. The friendship between the two is very unusual. It is very difficult for others to borrow heavy ion proton therapy equipment, but For Professor Li Hongwei, who is the vice president of Yenching University, it is a matter of one sentence.

"It won't be long before a few people from the public recruitment will come."

Zhao Heng said slowly.

"I heard that there are four people this time, do you want to come together?"

Liu Meng asked.

"Not four, but those who pass the written test will first come to the department to work for a short period of time, and then see the performance and finally leave four."

Zhao Heng corrected Liu Meng's statement.

"Is this what the director mentioned to the courtyard?"

As soon as Liu Meng heard it, he knew that Zhao Heng must have proposed it to the courtyard. A young genius like Zhao Heng values ​​efficiency and ability very much, so he is naturally unwilling to admit someone who is good at the exam but not capable. up.

Although the current doctor of medicine, postgraduate and doctoral courses are basically completed in hospitals, they are actually in contact with clinical practice.

But in fact, everyone's focus is different, and some people's clinical skills are really hard to describe.

"Cory is about to expand further, and urgently needs a group of people with practical working ability. If there are a few high-sighted and low-handed people coming in, it's better not to recruit."

Zhao Heng said.

Although the words are harsh, the reality is that the competition is so fierce now. Basically, all industries recruit people who are required to be able to work. No one has the resources and time to recruit people and cultivate them slowly.

As far as these few advanced training, regular training and intern doctors are concerned, so far, Zhao Heng has not found anyone worthy of emphasizing training.

"It is."

Liu Meng nodded in agreement. Now that the industry is so involuntary, there is a feeling that there is no time to cultivate it.

After leaving the ward, Zhao Heng came to the oncology department.

In the oncologist's office, Zhao Heng told Li Haiyang about the idea of ​​autologous tumor bone inactivation and replantation and heavy ion proton therapy, and Li Haiyang's eyes immediately brightened.

"How can you come up with so many ways at any time?"

Li Haiyang looked at Zhao Heng, and said enviously, as a doctor, Zhao Heng's flexible and sharp thinking was what he envied most.

"I figured it out just by thinking about it. It's not difficult."

Zhao Heng said casually.

"Maybe this is a genius, but the heavy ion proton therapy instrument of Yenching University is very precious over there. Last time I had a patient who wanted to use it, but I didn't get in the queue. When I did, I said that one of the parts of the instrument was broken. Now, we have to wait for the original factory to send it over.”

Li Haiyang said with a sigh.

At present, in terms of cutting-edge medical equipment, there is still a big gap between domestic and foreign countries. For the latest high-tech products such as heavy ion proton therapy equipment, they can only be imported, and they only teach you how to use them.

As for what the specific principle is, or even how to make it, I'm sorry, it's an absolute commercial secret, don't want to know it at all, after all, it's someone else's guy who eats.

"It shouldn't be difficult for me to contact Professor Li Hongwei."

Zhao Heng said.

"That's the benefit of having a relationship."

Li Haiyang said enviously.

Although he can be said to be an absolute relative of Dongfang Hospital now, because his teacher is the dean of Dongfang Hospital.

But this is what he got from his teacher for more than ten years. Unlike Zhao Heng, his development is like flying a plane.

"When the time comes, the surgery will be performed on your side."

Zhao Heng said indifferently.

Although he can also perform this tumor operation, it is obvious that Li Haiyang is also very skilled in this area, and removing the tumor bone is not a difficult operation.

"Okay, no problem, you can ask for it."

Li Haiyang smiled and agreed. He knew that Zhao Heng came to him and wanted to take him with him. After all, Zhao Heng is not a person who eats alone.

Such a highly experimental operation, especially in oncology, is very rare for oncologist Li Haiyang, and it is also a very precious opportunity for surgery.
