The world's first liver transplant was performed in 1963 by Professor Starzl of the United States, the father of liver transplantation.

At that time, it was a cadaveric liver transplant.

It is a cadaveric liver transplant, but the survival rate is very low.

It wasn't until 1988 that a doctor named Raia performed the world's first living-donor liver transplant on a four-and-a-half-year-old girl, but later developed severe hemolysis and died.

The following year, a living donor liver transplant was performed on a 19-month-old baby girl, but it failed.

That same year, an Australian doctor, Strong, transplanted his mother's liver to a one-and-a-half-year-old boy with congenital biliary atresia.

It's only 1986, and there are no successful examples abroad, let alone domestic. In terms of liver transplantation, China is very backward.

Of course, they don't know about these successful cases Song Tingshen, and only Guo Xiang, a later man, knows about them.

You can imagine how difficult a liver transplant is.

But this does not mean that there has not been a liver transplant in China, there is.

From 1973, there were also experts and professors in China who began to study liver transplantation, and from 1977 to 1983, more than 50 cases were carried out, but 90% of the patients died during the operation or three months after the operation, and the longest lived for more than 200 days.

Later, the domestic liver transplant calmed down and there was no breakthrough.

Now Song Tingshen just wants to make a breakthrough, right?

However, Guo Xiang knew that it was not until 1997 that the first living donor liver transplant in China was successful, and this road was too difficult.

Even if the liver cancer patient can be transplanted, it will be a cadaveric liver transplant, because the current technology of living donor liver transplantation is not yet available.

But even cadaveric liver transplantation is very difficult right now.

The so-called corpse liver is not really used in the liver of a dead person, but the liver of a patient who has just died or is brain dead, so it is more difficult to obtain. It's even more difficult to match it just right.

Even so, it would be nice to have 10,000 people out of a million patients receive organ transplants every year, let alone in a time when there was no such system.

Chinese people generally pay attention to the whole body of the dead, and put it into the ground for peace, and the concept of people in this period is still very backward, even if the body donation is advocated, no one responds.

Generally, organ transplants and medical corpses are death row prisoners or ownerless corpses without relatives, but such corpses are also very rare, so it is very difficult to use organs.

This is also one of the reasons for the stagnation of organ transplantation in the country.

Song Tingshen wanted to have a liver transplant, but it was very difficult.

"Even if this patient can be touched, it will be too late." Song Tingshen sighed, there was no time, he didn't believe that in just three months, they could break through so many techniques that experts and scholars couldn't break through.

"Teacher Song, we can try, even if this case is not successful, as long as we don't give up, we will succeed one day, so that we can benefit future people." Guo Xiang said.

She actually had a liver transplant, but now the conditions are limited, the medical equipment is limited, and many things are still not up to her, but she will try her best to help Teacher Song.

"Yes, Mr. Song, how do you know if you don't try?" An Zehan was excited, liver transplantation, this is a global problem, and it is so meaningful for me to have the opportunity to participate.

Song Tingshen nodded, "It's good if you are determined, the progress of medicine depends on aspiring young people like you." Let's try it together! ”

"Good!" Guo Xiang stretched out his hand and motioned to An Zehan, he hesitated a little, came to his senses, put his hand on Guo Xiang's hand, and Song Tingshen also put his hand on An Zehan's hand.

The three of them shouted in unison: "Let's work together!" ”

"Then where to find the liver source now?" An Zehan rubbed his hands and was eager to try.

"In the past, Professor Lin used dogs' livers for experiments, and we can do the same!" Song Tingshen said.

"Huh? How pathetic is that dog? An Zehan frowned.

Song Ting glanced at him deeply, "When you were doing experiments at school, weren't frogs pitiful?" Rabbits are not pitiful? ”

"How is that the same? Dogs are very spiritual! An Zehan pouted.

"In this way, we go to the countryside to collect some stray dogs, wild dogs, some of those dogs are very fierce, some may also have rabies, often bite people, it is better to catch them, not only to eliminate harm for the people, but also to contribute to the cause of medicine, why not?" Guo Xiang said.

"That's a good idea!" Song Tingshen nodded.

"Then I'll go find someone to help and go to the countryside to collect the dogs!" An Zehan became excited.

"Twenty first, preferably alive." Song Tingshen said.

"And where was the adoption?" An Zehan asked.

"Let's go to the suburbs and rent a house, lock the dog in a cage, ask someone to keep it, and get it when we need it." Guo Xiang said.

"Good!" Song Tingshen nodded.

"Wait for your dog to be collected, let's go together, I'll drive, and we'll go to the suburbs to find a house." Guo Xiang said to An Zehan.

"Hey!" An Zehan smiled, "No, I'm going to learn about liver transplantation right away, we have a book on this in the school library, right?" ”

"I have it there, and I'll bring it to you tomorrow." Song Tingshen said.

The next few people began to prepare for the liver transplant project.

An Zehan grabbed the dog from the countryside and placed it with Guo Xiang in a rented farmhouse in the suburbs.

Ten of the dogs were given liver cancer-inducing drugs in their drinking water to get liver cancer. This is the same as experimenting with mice, except that the dosage is increased according to the weight of the dog.

Song Tingshen began to prepare a laboratory for surgery in the school, which is definitely not possible in the People's Hospital, this is a school project, and it can only be carried out in the school.

Fortunately, Song Tingshen applied for this project a long time ago, and there were scientific research funds, and he finally got enough equipment.

However, Guo Xiang looked at these devices, and they were too different from those of later generations, so he had no choice but to use them first.

It also takes time for dogs to suffer from liver cancer, and during this period, several of them still work in the hospital as usual, but as soon as they are free, the three of them discuss together, Guo Xiang put forward a lot of new ideas, and Song Tingshen was very surprised.

"How do you know so much?" Song Tingshen was very strange. Even if she was a doctor before she lost her memory, she was not as strong as an old doctor with more than ten years of medical experience, right? How does she understand so much?

"Uh......" Guo Xiang didn't know what to say, "I don't know, I think it may be that I have read books on this subject before, my foreign language is very good, I should have read medical literature in foreign languages." ”

"Before that, Dr. Lin Wen said that it is really possible that your home is in the capital, and you are still attending university in the capital." An Zehan said.

Guo Xiang laughed awkwardly, "Maybe!" ”

"It's strange to say, he hasn't come since Dr. Lin made a fuss last time, has he given up?" An Zehan asked, after which he also learned about Guo Xiang's "amnesia", so he doubted that what Lin Wen said was true.

However, Guo Xiang is married, even if it is true, it is too late.

"Your parents didn't come looking for you either?" Song Ting asked suspiciously.

Guo Xiang's expression darkened, "Maybe they don't want to recognize me either?" ”

Song Tingshen patted her on the shoulder, "Then let it be." ”

Guo Xiang nodded, as long as you don't scold me, I don't want to recognize them.

Now it seems that Lin Wen really didn't say his existence, and that selfish person would not be so enthusiastic about things that are not beneficial to him.
