Allogeneic transplantation refers to the transplantation of cells, tissues, or organs between individuals of the same species and different genotypes to receive recipients from genetically different donors of the same species.

In fact, most transplants of human tissues and organs are allogeneic transplants.

To put it bluntly, my kidney is transplanted to you, or my cornea is transplanted to you, not my kidney transplanted to your liver, which is called a bull's head and not a horsetail.

Allogeneic skin grafting, on the other hand, is the transplantation of other people's skin onto a burn patient, preferably from site to site.

Hearing Chen Qi's suggestion, Professor Peng was the first to raise objections:

"Dean Xiao Chen, I want to say a few words about this, we have also tried the allogeneic skin graft you mentioned in the clinic, but the effect is not very good, and there are two problems that cannot be solved.

One is the problem of survival rate after skin grafting, and the second is even more serious, that is, the problem of immune rejection caused by transplantation. ”

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

Each person's immune system has a unique identity, so an allogeneic skin graft is sure to cause rejection.

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

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

In an allogeneic skin graft, the patient's immune system perceives the grafted skin as a "foreign object" and rejects it.

The severity of rejection varies from individual to individual.

In some cases, rejection may be mild, manifesting only as redness, swelling, 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 a few hours after surgery at the earliest.

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

After the second transplant, I have to take a lot of anti-rejection drugs, which are very expensive, and I have to take them, which is not 100% guaranteed.

There is also a problem with skin grafts, where you cut out someone else's skin and transplant it onto a patient, and rejection will almost certainly occur.

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

After hearing Professor Peng's question, Chen Qi quickly explained:

"No, no, no, you have misunderstood, the allogeneic skin graft I want is not for real, I need to temporarily protect the patient's wound and control the current infection, and then I want to seize the time to graft the skin before the granulation tissue grows."

When several old professors heard this, they were relieved, they now wanted to "steal" the tricks and secret recipes of the Vietnamese Central Chinese Hospital, but they didn't want Chen Qi to mess around and finally kill the patients.

That's 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 College raised another question at this time:

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

It's still quite scary to take skin, especially from a living, normal person.

This requires the use of a "skin extractor", just like peeling loofahs and lettuce when cooking, which has to be scraped off layer by layer.

If you still can't understand it, think about Ming Taizu Zhu Yuanzhang skinning corrupt officials alive, stuffing straw into it and showing it to everyone, you can know how cruel this is.

If there is no filial son in front of the bed for a long time, let the patient's children or parents cut off their own skin and then give it to the patient, if they don't use moral kidnapping, they generally refuse.

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, lest people be restless, so I decided to go to someone else to find a way."

Zhang Xing said weakly: "The family members are unwilling, how can others be willing?" ”

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

Out of the south gate of Yuezhong City, out of the city is the Wangqin Mountain of Jiuli Village.

This mountain is very famous, when Qin Shi Huang went south to Huiji Mountain, it was to climb the Qin Mountain to overlook the sea, and then the poetry was great, so that Li Si wrote an article engraved on the top of the mountain, which is the famous "Huiji Carved Stone".

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

After looking at Qinshan, it is a continuous mountain, and the first to go south is Pingshui Town.

There is a stream called "Ruoye Creek" in Pingshui Town, the name is very beautiful, the scenery is even more beautiful, the ancient literati liked it very much, and they watched the movie and left poems.

For example, Li Bai came to play and wrote a poem: "Ruoye Creek picks lotus girls, laughing at lotus flowers." ”

Su Shi wrote a poem: "Ruoye Creek Water Yunmen Temple, He Jian lotus flowers open empty." ”

Lu You wrote a poem: Plum Thousand Trees on Ruoye Creek, I have been wearing a short tent this year.

Liu Yuxi also wrote a poem: "Tomorrow, the Han Court will conquer the old virtues, and the old man will fight for Ruoye Creek." ”

But it is such a beautiful place, those uneducated bigwigs not only did not think about developing tourism, but built a "garbage disposal site" on the bank of Ruoye Creek.

It may be to facilitate one-stop service, after all, it is not far from Qinshan Mountain, so it is easier to pull it over.

When he came out of the courthouse, he went directly to the Ruoye River, knelt down, and then groaned.

Therefore, the bank of Ruoye River in Pingshui Town has become the terminal station of those who are extremely vicious, and they can still enjoy the beautiful scenery before they die, which is very good, and it is also romantic to be a ghost.

In such a resentful place, who dares to travel, who dares to come to a picnic, and Yaxing will chant a poem again, not afraid that Ah Piao will follow home?

Chen Qi is here.

Of course, he wasn't here to enjoy the view, and he was chatting with a criminal who was about to see his grandmother.

"Shen Laosan, that's right, you won't be able to live today anyway, and you know the nature of the things you did before, so you can't complain about what happened to you today."

This Shen Laosan had a stalk in his neck, and said indifferently: "Lao Tzu is a good man again after eighteen years!" ”

"Yes, yes, you are dead, but have you ever thought about your eighty-year-old mother, three-year-old little doll, you are dead, your wife has run away, how do you let your old mother and your little doll live? Do you know how much rations you have left in your house? ”

"I, my mom is not eighty years old, she is only in her fifties...... Woo woo, I'm sorry for my mom, I'm sorry for my baby......"

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

Chen Qi patted him on the shoulder:

"So, you leave them some money before you die, this is also your last contribution as a son and a father, as long as you sign and agree, when I take your human skin, I promise to let Yue Steel Mill pay your mother 3,000 yuan, they don't pay, I will pay this money!"

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 good, you can skin me directly 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, even if you still have a little conscience, don't worry, I will definitely hand over this money to your mother, just skin people alive, I'll peel it when you leave."

At this time, there were already policemen shouting at the door: "Dean Chen, the time is almost up, if you have something to say, please explain it quickly." ”

Chen Qi grabbed the "Certificate of Voluntary Donation of Remains" signed by Shen Laosan and pressed his fingerprint, and stood up as well:

"Okay, I'll be right away. Shen Laosan, be a good person in the next life. ”

Shen Laosan, who was not afraid of heaven and earth, heard "three o'clock in the afternoon", 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 waist, my liver, you want to take everything, can you not shoot me~~~"

Chen Qi glanced 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 use hemp rope to put Shen Laosan's hands behind his back and then tied them up, and only the chains on his feet would be opened after he died.

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

If you know today, why bother in the first place?

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

See if they want to sin in the future, if they want to die?

In later generations, some people have been clamoring for the abolition of the death penalty, saying that this is inhumane, which is as brainless as farting.

On the contrary, the death penalty is set too little, catch one and shoot the other, see who dares to step on the red line of the law?

Like a human criminal, if you sell a child or a woman, you can shoot it directly, and you can definitely achieve a world that does not close your door at night and everyone is friendly.

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

Chen Qi and Zhang Xing quickly ran forward with the toolbox, and at this time, Shen Laosan's head had already blossomed.

Originally, I had to go through the procedure, to verify the identity, to take pictures for the record, and to confirm the death.

However, 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 refreshed, took a stick and stirred it into Shen Laosan's already broken head, and then slapped a criminal with only half of his head left, and then nodded:

"Dean Chen, it's okay, you can take it away."

The body was not brought back to the Viethorng-chug Hospital in the city, but found a room near the execution site and immediately began to peel the skin.

Because the most advanced "skin extractor" can only take 102mm of skin width, it does not meet the requirement of covering the entire layer of patients with large burns.

So Chen Qi took matters into his own hands and used a scalpel to quickly cut off the skin of Shen Laosan's entire body.

Fortunately, Chen Qi belonged to a skilled fast knife player, and in less than an hour, the entire human skin was completely removed.

Before he could admire his masterpiece, the human skin was placed in a safe box with ice cubes in advance, and he got into the car and made a quick trip to the hospital.

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

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

In this way, the patient's wound is no longer exposed, thereby reducing the risk of infection by various bacteria and helping the patient to get through the dangerous period.

That night, Chen Qi personally took 4,000 yuan, found Shen Laosan's home, and handed over the money to Shen Laosan's mother in person, which can be regarded as fulfilling his last promise to the deceased.

Among them, 3,000 yuan was paid by the Vietnamese Iron and Steel Plant, and 1,000 yuan was paid by Chen Qi's private pocket.

In 1989, 4,000 yuan was definitely a huge amount of money for a rural family, at least there was no problem with food, and it should be able to provide for a child to complete nine years of compulsory education.

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

The next day, three of the students developed fevers.

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

As an aside, many people die of nervousness when they have a fever after a cold, and they want to go down to the fever even if they don't hesitate to overtreat, which is actually the wrong approach.

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

The process of attack and devouring is the process of fever, that is, metabolism.

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

You can observe that those who are usually physically weak often have a long course of illness after encountering infection, generally about ten days to half a month, and the symptoms can improve.

On the contrary, those who are physically strong, although they have a fever, will feel unwell, but the course of the disease is generally shorter, and the symptoms improve in five to seven days.

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

Lan Lijuan had been closely observing the 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 produce some antibodies, which requires a process.

Finally, on the third day, Lan Lijuan got her wish to get blood with antibodies to specific bacteria, which was also quickly transfused into worker Lu Wenjie.

Three health school students were also hospitalized for observation, and Chen Qi gave them the best antibiotics.

Now that burn patients are on artificial hibernation, ventilators are on ventilators, and the infusion plan has been adjusted, just when everyone thought that the patient could recover quickly, the accident appeared again.

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

Again, the problem was in the right leg with the most burns and infections.
