Allogeneic transplantation refers to cells, tissues or organs transplanted between individuals of the same species with different genotypes, to a recipient from a genetically different donor of the same species.

In fact, most human tissue and organ transplants are allogeneic transplants.

To put it bluntly, my kidney is transplanted to you, or my cornea is transplanted to you, instead of my kidney being transplanted to your liver.

The allogeneic skin transplantation is to transplant the skin of other people to the burn patient, and it is best to have the same part to part.

After hearing Chen Qi's suggestion, Professor Peng was the first to object:

"President Xiao Chen, I would like to say a few words about this. We have also tried clinically the allogeneic skin transplantation you mentioned, but the effect is not very good. There are two problems that cannot be solved.

One is the problem of survival rate after skin transplantation, and the second is more serious, that is, the problem of immune rejection after transplantation. If these two problems are not resolved, allogeneic skin transplantation will almost certainly fail, and there will be no way to cure it. disease, it will aggravate it. "

Several other old professors also echoed, thinking that this method is too unreliable.

Every person's immune system has a unique identity, so allogeneic skin transplants will definitely cause rejection.

Rejection is when the body's immune system attacks a transplanted tissue or organ.

When the immune system detects foreign objects, it produces antibodies and cells to try to destroy them.

In a skin allograft, the patient's immune system perceives the grafted skin as "foreign" and rejects it.

The severity of rejection varies from individual to individual.

In some cases, rejection may be mild, with only redness or itching of the skin.

But in other cases, rejection can be severe, leading to necrosis of the grafted skin or other complications. In addition, rejection can occur at any time, with adverse reactions occurring as quickly as hours after surgery.

So, like organ transplants, the requirements for skin transplants are very high. One is that they need to be paired before transplantation, and not all organs of dogs or cats can be used.

After the second transplant, he will still need to take a large amount of anti-rejection drugs, which are very expensive and have to be taken. This is not a 100% guarantee.

Skin transplants also have this problem. When you cut someone else's skin and transplant it to a patient, rejection will almost certainly occur.

At that time, not only will the skin grafting fail, but the rejection reaction will break the patient's already fragile immune system, and the skin will ulcerate and cause severe infection, which is really harmful.

Chen Qi quickly explained after hearing Professor Peng's question:

"No, no, teachers, you have misunderstood. The allogeneic skin transplant I want is not for real. I need to temporarily protect the patient's wound and control the current infection. Then I want to take advantage of the granulation tissue. I took the time to get a skin graft before."

The old professors were relieved when they heard this. Now they want to "steal" the tricks and secret recipes of Yuezhong Hospital, but they don't want Chen Qi to mess around and kill all the patients.

It would be a big loss, you must know that the time of these old people is also very precious.

Professor Wang from the Second Hospital of Zhejiang Medical University raised another question at this time:

"Xiao Chen, if it is allogeneic skin transplantation, the best choice is the skin of the immediate family members, so that the rejection reaction can be minimized, but if you want to take skin from a living person, whether the family members are willing or not is still a question."

Taking skin is quite scary, especially taking skin from a living, normal person.

This requires a "skin remover", just like peeling loofah and lettuce when cooking, it needs to be scraped off layer by layer.

If you still don't understand, think about Ming Taizu Zhu Yuanzhang skinning corrupt officials alive and stuffing them with straw for everyone to see, you will know how cruel it is.

There are no filial sons in front of the long-term hospital bed. Let the patient's children or parents cut off their own skin and use it for the patient. If it is not morally kidnapped, they are generally unwilling.

Relatively speaking, parents are more likely to be willing, and children are almost never willing.

Chen Qi shook his head:

"Let's not test human nature anymore, lest people's homes will be uneasy, so I decided to go to others to find a way."

Zhang Xing said weakly: "The family members are not willing, how can others be willing?"

Chen Qi already had an idea: "Others can..."

Out of the south gate of Yuezhong City, you will find Wangqin Mountain in Jiuli Village.

This mountain is very famous. When Qin Shihuang visited Kuaiji Mountain in the south, he climbed up to look at the Qinshan Mountain and overlooked the sea. Then his poetry became so popular that Li Si wrote an article and carved it on the top of the mountain. This is the famous "Kuiji Carved Stone" .

Later, a crematorium was built at the foot of Wangqin Mountain, which became the end of everyone's life.

After Wangqin Mountain, there are continuous mountains. If you go south, you will arrive at Pingshui Town first.

There is a stream in Pingshui Town called "Ruoye Stream".

For example, Li Bai came to play and wrote a poem: "Ruoye River is next to the lotus picking girl, laughing across the lotus and talking to people."

Su Shi wrote a poem: "Ruoyexi Shuiyunmen Temple, Hejian lotus blossoms in the sky."

Lu You wrote a poem: Ruoye River has plums and thousands of trees, for a long time I tied a short canopy this year.

Liu Yuxi also wrote a poem: "Tomorrow the Han court will conquer the old virtues, and the old people will fight for the Ruoye River."

But it is such a beautiful place, those uneducated bosses not only didn't think about developing tourism, but instead built a "garbage disposal site" by the Ruoye River.

It may be for the convenience of one-stop service. After all, Qinshan Mountain is not far away, so it's easier to pull over.

Come out of the court and pull it directly to the Ruoye River, kneel down, and then bang bang.

So the bank of Ruoye River in Pingshui Town has become the terminal station for those vicious people, and they can enjoy the beautiful scenery before they die.

In such a place with resentment, who dares to travel, who dares to have a picnic, and Yaxing to recite a poem, isn't he afraid that Ah Piao will follow him home?

Chen Qi is here.

Of course he didn't come to enjoy the view, at this time he was chatting with a criminal who was about to meet his grandma.

"San Shen, the reasoning is that you won't live today anyway, and you know the nature of the things you did before, so you can't blame heaven or earth for what happened to you today."

The old man Shen had a stalk in his neck, and said indifferently: "I will be a good man again after eighteen years!"

"Yes, yes, you died at once, but have you ever thought about your eighty-year-old mother and three-year-old baby, you died, your wife ran away, what happened to your old mother and your little baby?" Living? Do you know how much rations your family has?"

"I, my mother is not eighty years old, she is only in her fifties... Woohoo, I am sorry for my mother, sorry for my baby..."

Speaking of family members, Shen Laosan's voice became softer and softer, his previous self-paralysis also failed, and he began to cry.

Chen Qi patted him on the shoulder:

"So, you leave some money for them before you die. This is your final contribution as a son and a father. As long as you sign and agree, after I take your human skin, I promise to let Yue Steel Factory pay for it." They won't pay your mother's 3,000 yuan, so I'll pay for it!"

Shen Laosan gritted his teeth and agreed:

"Okay, others can't believe it, but Dean Chen, you and I can trust it. It's really not possible. You can just peel my skin before I shoot it. Anyway, my skin is useless."

Chen Qi also thought, this way the peeling effect is better, but this is too inhumane.

"Okay, Shen Laosan, you still have a little conscience, don't worry, I will hand over the money to your mother with my own hands, just peel the human skin alive, I will peel it after you leave."

At this time, there were policemen shouting at the door: "Dean Chen, it's almost time, you have something to say quickly."

Chen Qi grabbed the "Certificate of Voluntary Body Donation" signed and fingerprinted by Shen Laosan, and stood up at the same time:

"Okay, I'll be fine soon. Third Shen, please be a good person in your next life."

Shen Laosan, who was not afraid of anything, heard "It's 3:00 noon", his legs suddenly weakened, and he began to howl:

"Dean Chen, I don't want to die, I don't want money, I voluntarily donate my human skin, my kidney, my liver, you take everything you want, can you not shoot me~~~"

Chen Qi looked back at this heinous criminal, shook his head slightly, and walked out of the interrogation room without looking back.

Several policemen rushed into the house, and began to tie Shen Laosan's hands behind his back with hemp rope, and then tied them tightly.

Chen Qi walked farther and farther, and heard Shen Laosan howling in the house, the crazier: "I don't want to die, I don't want to die, save me, save me~~~"

If I knew today, why bother?

Chen Qi felt that it was necessary to bring all the criminals in the prison and the leaders of the aircraft units at all levels to the execution ground, so that they could see and hear with their own eyes.

See if they want to commit crimes in the future, do they want to die?

Some people in later generations have been clamoring for the abolition of the death penalty, saying that such an inhumane spirit is as mindless as farting.

On the contrary, the death penalty is set too little. If one is caught and shot, who dares to step on the red line of the law?

Like a criminal, who traffics a child and woman and shoots them directly, it is absolutely possible to achieve a world of great harmony where everyone is friendly.

Half an hour later, by the Ruoye River, a gunshot rang out.

Chen Qi and Zhang Xing ran forward quickly carrying the toolbox. At this time, Shen Laosan's head was already blown.

Originally, there were still procedures to be followed, such as verifying the body, taking pictures and keeping files, and confirming the death.

But Chen Qi wanted to take the human skin while the corpse was still fresh, so he shouted at a forensic doctor: "Captain Liu, hurry up."

Forensic doctor Liu was also straightforward. He took a stick and shook Shen Laosan's broken head, and then patted the criminal with only half of his head left. Then he nodded and said:

"Dean Chen, it's fine, you guys take it away."

The corpse was not taken back to the Yuezhong Hospital in the urban area, but found a room at the execution ground nearby, and the skinning work was carried out immediately.

Because the most advanced "skin extractor" can only take the skin with a width of 102mm, which does not meet the requirement of full-layer coverage for patients with large area burns.

So Chen Qi did it himself, using a scalpel to quickly cut off the skin of Shen Laosan's entire body.

Fortunately, Chen Qi belonged to a skilled swordsman, and within an hour, the entire human skin was completely removed.

Before he could appreciate his masterpiece, the human skin was put into a safe box with ice cubes in advance, and he got in the car and headed for the hospital quickly.

The body of Shen Laosan was put into a body bag and sent to the Wangqinshan Crematorium. In the end, a handful of ashes were left and were sent to the farm as fertilizer.

After the skin was sent to Yuezhong People's Hospital, the burn department immediately covered the worker Lu Wenjie with a layer of Shen Laosan's fresh human skin.

In this way, the patient's wound is no longer exposed, thereby reducing the risk of being infected by various bacteria and helping the patient survive the dangerous period.

That night, Chen Qi took 4,000 RMB in person, found Shen Laosan's home, and handed the money to Shen Laosan's mother in person, fulfilling his last promise to the deceased.

Among them, 3,000 yuan came from Yue Steel Factory, and 1,000 yuan came from Chen Qi's personal pocket.

In 1989, 4,000 yuan was definitely a huge sum of money for a rural family. At least food was no longer a problem, and it should be enough for children to complete nine years of compulsory education.

The rest, Chen Qi can't control it to the end, good and evil will be rewarded, what happened to the Shen family today, maybe this is the retribution for the robbery and murder of Shen Laosan.

The next day, three health school students started to have a fever.

When bacteria invade the human body, the body's immunity will fight with these invaders, and this process is fever.

To make a digression, many people are nervous and dead when they have a fever after catching a cold. They want to get rid of the fever, even over-treatment. This is actually a wrong approach.

Generally after a cold, bacteria and viruses invade the human body, and white blood cells, neutrophils, lymphocytes, etc. in the body will be activated to attack bacteria or viruses from exogenous sources.

The process of attacking and devouring is the process of fever, which is the metabolism.

Appropriate fever will increase immune function and increase the strength of the immune system.

You can observe that those people who are usually weak in constitution often have a long course of disease after encountering infection. Generally, it takes about ten days to half a month before the symptoms improve.

On the contrary, those with strong physique, although they may feel uncomfortable when they have a fever, the course of the disease is generally shorter, and the symptoms improve in five to seven days.

So fever can promote blood circulation, promote metabolism in the body, increase the body's immune function, and help prevent or eliminate infection.

Lan Lijuan has been closely observing three health school students, and she was waiting after the students started to have a fever.

Because bacteria will form antigens after entering the body, and the antigens will stimulate the B lymphocytes and immune system in the body to automatically generate some antibodies, which requires a process.

Finally on the third day, Lan Lijuan obtained blood with specific bacterial antibodies as she wished, and was quickly infused into worker Lu Wenjie.

Three health school students were also arranged to stay in the hospital for observation, and Chen Qi gave them the best antibiotics.

Now the burn patients are put on artificial hibernation therapy, the ventilator is also on, and the infusion volume plan has also been adjusted. Just when everyone thought the patient could recover quickly, the accident happened again.

The transfusion of blood with bacterial antibodies only lasted for 2 days, and Lu Wenjie's condition began to deteriorate again after 2 days.

The problem was still the most burned and most infected right leg.
