Guo Xiang came out of the electrical appliance factory and went home, and he didn't live for a while and the ashes fell, and he did a good job of hygiene, and he will come back to live in a few days.

By the way, I called Hao Weidong and asked him to help pay attention to it to see if there was a suitable courtyard house for sale.

"You're coming to the capital?" Hao Weidong was surprised, isn't it good in the Northeast?

"No, I don't have any plans yet, don't I have some spare money to buy a suite now." Guo Xiang said.

"If you want to buy it, you can buy it there, what are you doing in the capital, where are you free?" Hao Weidong still didn't understand.

Guo Xiang didn't know how to explain to him, could it be that even if he was idle there, it would be worth a lot of money, it didn't make sense.

"Hey, don't care what I'm doing, you just think I'm rich to burn, I'm willing, you help me inquire, those famous alleys, Dongcheng Dengshikou West Street, Xicheng Qianhai, Mao'er Hutong...... Anywhere, it should be good, it should be big, it is best to be the mansion of the former prince Baylor, magnificent, well protected......"

"You're going to be restored?" Hao Weidong smiled, and at the same time shocked in his heart, this Guo Xiang felt that he knew the capital better than himself.

Guo Xiang smiled, "I don't have that ability, I just want to buy a land to retire in the future and live comfortably!" ”

"How old are you? Just retirement? Hao Weidong rolled his eyes.

"Oh, don't worry about it so much, do you say you can't help?" Guo Xiang said with a smile, "I won't let you help in vain, and I will give you a commission, how about it, but you must do a good job, you want a good house, and you must be able to transfer the ownership with a real estate certificate." ”

"Okay, I'll keep an eye on you. When to do it? Hao Weidong said.

"The sooner the better, of course." Guo Xiang said, the main thing is that the sooner you buy it, the cheaper it is.

"Okay!" Hao Weidong was a little helpless, as if he was in a hurry to get married.

"Thank you then, hang up."

After hanging up the phone, Guo Xiang was in a very good mood, and when he thought that there would be hundreds of millions of real estate in the future, his heart was about to fly.

……

After the fifteenth day of the first lunar month, Guo Xiang and Gu Zhennan returned to the city together.

Gu Zhennan went back to the University of Petroleum to attend classes, and Guo Xiang went back to the Medical University.

"Let's start the liver transplant experiment today, let's go see our dog first." Song Tingshen said.

"By the way, Mr. Song, how is the patient with advanced liver cancer?" Guo Xiang asked.

"Not so good." Song Tingshen shook his head, "It's been three months, the effect of the medicine is limited, he himself bought the medicine from abroad and came back, it's a little better, but it can last for a month at most." ”

"Then we're going to have to hurry up here." An Zehan said.

"You think it's that easy? What other experts and professors haven't done for a few years, we can do it in a month? Song Ting glared at him deeply.

"It's good to make a little progress, this person can't do it, and there is the next one, he is not the only one who has liver cancer." An Zehan said.

That's right, Song Tingshen didn't say anything more.

"By the way, let's all go for a rabies vaccine first, in case some dogs carry rabies virus and we accidentally injure ourselves during surgery, and it is a little more reassuring to have a prevention." Song Tingshen said.

"Good!" Guo Xiang nodded.

Normal people can also be vaccinated against rabies.

Rabies vaccine injection can be divided into pre-exposure prophylaxis and post-exposure prophylaxis.

Before exposure, if you have not been bitten by a dog, for example, people who often deal with dogs and cats, such as veterinarians, or some scientists who study the rabies virus, need to be vaccinated against rabies in advance, just in case.

Needless to say, after being exposed, you must be beaten if you are bitten by a dog, although you may not have rabies, but the fatality rate of rabies is very high, and once you get sick, you will basically be hopeless, so you must be beaten if you are bitten by a dog.

The three of them first went to the epidemic prevention station to get the rabies vaccine and get the first shot. Before exposure, three injections are given, the second one on the seventh day and the third one on the twenty-first day. This is how it can be fully effective. So they still have to pay great attention to this time.

Guo Xiang drove the car, and the three of them went to a rented farmhouse in the suburbs, where more than 20 dogs barked when they heard a car coming.

Song Tingshen took the anesthetic gun prepared in advance, anesthetized all the dogs first, and drew blood.

Dogs also have blood types, but they are different from humans.

Because for a liver transplant to be matched, blood needs to be drawn.

However, the liver is an immune-exempt organ, as long as the blood type is the same, it is basically fine, unlike the kidney, in addition to the blood type, but also gene loci, population response antibody and lymphocyte toxicity cross-match test, etc., as long as a few points do not match, it will not work, and the liver transplant matching is much simpler.

Therefore, liver transplants were far more common than kidney transplants in later generations.

And the liver is the only regenerative organ, that is, if it is cut in one-third, it can grow on its own, and if it is cut two-thirds, it can still live, but the quality of life may not be so good, but it will not die.

Therefore, many later generations are liver donations between relatives, and the impact on recipients and donors is relatively small.

But the current technology is still very poor, and living donor liver transplantation is difficult.

Song Tingshen measured the blood types of all the dogs, found two blood types that matched between liver cancer and normal dogs, put them in cages, and brought them to school.

The school's laboratory is located next to the dissection room, which is quiet and does not disturb others, and students do not usually come here to play.

After all, there are corpses, although they are not afraid, but they are still taboo.

The surgical instruments are well prepared, and there are various instruments, which are similar to those in hospitals, but they are old.

In order to avoid heavy bleeding during the operation, two bags of blood were drawn on the healthy dog, which he was going to sacrifice anyway.

Then the anesthetic dose was increased, the dog was brought to a near-death state, which is equivalent to human brain death, and the liver was cut off.

A liver transplant is a whole liver transplant, in which the whole liver of a dog with cancer is cut off and transplanted into the liver of a healthy dog.

The sick dog was under general anesthesia, and his blood pressure was monitored, and the diseased liver was removed.

Then the gallbladder of the donor liver should be removed, and the blood vessels and biliary tract of the donor liver should be trimmed to make it suitable for the blood vessels of the sick dog.

"Why did you have your gallbladder removed?" An Zehan asked, after all, he didn't understand these things if he hadn't done a liver transplant.

"Because the gallbladder has a very poor tolerance to ischemia, in order to reduce postoperative biliary complications, it is better to say that gallbladder removal has little effect on the receptors." Guo Xiang said.

"The knowledge is not firmly grasped." Song Tingshen glanced at An Zehan.

He smirked, where did he remember so much.

Song Tingshen perfused the donor liver, because once the liver is out of the body, it will be ischemia, and the ischemia will die for a long time, so it is necessary to perfuse, which is also the place where cadaveric liver transplantation is not as good as living transplantation, and living transplantation does not have this problem.

Put the donor liver into the dog's body, anastomostomose the superior and inferior vena cava, portal vein, and hepatic artery, anastomoses the biliary tract, and then close the abdomen.

Of course, just doing this for several hours, Guo Xiang and An Zehan worked on the side.
