Guo Xiang and the twins lived in southern Hunan for more than ten days. They didn't return to the capital until Shen Meng had a full moon wine.

The hospital still has work. Naturally, you can't stay there all the time.

When she returned to the capital, Gu Zhennan also came back from Saudi Arabia and tanned a lot.

However, he said that Saudi Arabia's oil production has been very good, and new oil fields are still being developed one after another. There is no need to worry at all.

Back in the capital, Guo Xiang rested for a day and went back to the hospital.

Not long after work, several people came in from outside.

"Hey, come one by one. Wait outside first!" Guo Xiang said.

"We are together!" The leading man said, pointing to the man beside him, "this is my wife, and the last three are my sons."

Guo Xiang was surprised. It's really rare for a family to come down.

"Who's uncomfortable?" Asked Guo Xiang.

"Me!" The middle-aged woman on the side sat down. She seemed to be about 50 years old, pale and in bad spirits.

"Sit down. What's wrong?" Asked Guo Xiang.

The man on the side took out the woman's medical record, "doctor, my wife has kidney disease and uremia. She has been dialysis for three years."

It is very serious. Guo Xiang took the woman's medical record, opened it and looked at it. It was done by the local hospital. Indeed, he had been dialysis for three years.

"The doctor said her kidneys were dead, and dialysis couldn't be done for long. We thought about whether we could change them." The man continued, "I'm a sailor. I've been running a boat outside these years. My wife supports me at home and has to pull three older children. She's tired and ill..."

The man's face was guilty, and the faces of his three sons were full of worry.

"I've also saved some money over the years. I'd better think about changing my kidney. I don't have to worry about it in the future. Doctor, do you think my wife will be all right as long as she changes her kidney? " Asked the man.

Guo Xiang pondered for a moment and said, "it's hard to say. The survival rate is caused by many factors. Generally speaking, the one-year survival rate after kidney replacement is 80%, the five-year survival rate is 60%, and it is also possible for more than ten years. "

"Then we'll do it!" The man looked at the three sons, and the three sons nodded.

"Is it for the child to donate a kidney to his mother?" Guo Xiang finally understood the reason why the whole family came, "have you ever done matching before?"

"Not yet." The man shook his head. "I always wanted to see it again. Now I can't delay it any more. It's not so easy to wait for someone else's kidney, so it's better for my own family. Fortunately, I have three sons. "

"But the doctor said that kidney replacement surgery is also dangerous. I inquired about it. I heard that the doctors in our hospital are skilled, advanced equipment and many imported drugs. We don't need money now. We need the best and succeed at one time!" Said the man.

"Yes, let's go to hospital first and make matching first!" Guo Xiang nodded and liked this rich owner.

"Do you all know your blood type?" Guo Xiang asked his three sons.

"I don't know!" The three shook their heads because they didn't match the type, had never been seriously ill before, didn't lose blood, and didn't know their blood type.

"It's all right. We have to check the matching type anyway." Guo Xiang nodded, "aunt, we should also have a comprehensive examination to see if we can change the kidney."

"OK, doctor, please arrange it!" Said the man.

Guo Xiang opened a hospitalization form and let the woman stay. The other four found a hotel outside.

On the second day, Guo Xiang began to examine women for many tests, such as blood routine, urine routine, liver function, kidney function, hepatitis B, electrocardiogram and so on.

After a few days of examination, the woman's body still met the conditions for kidney replacement, so Guo Xiang began to ask her three children to match her.

The man also said that whoever can match will donate a kidney. In the future, the son's small family will compensate him more money.

Although life can continue without a kidney, the body will still be a little worse than before, and the quality of life is not so good. Some compensation should be made.

The matching of renal transplantation is not the same as the blood group. Four conditions should be met.

The first is the blood type. ABO blood group matching, blood group must match. Kidney transplantation is also in line with the principle of blood transfusion. For example, people with type O blood can match people with type A, type B and type ab. Type A and type B can also be matched for type ab.

The second is lymphotoxicity test. Also called cross fit test. The normal value is less than 10%, and more than 15% is positive. In general, try to select the recipient with the lowest value for renal transplantation.

The third is human leukocyte antigen (HLA). This item plays a very important role in kidney transplantation. This item has six loci, and more than three loci can be used. Of course, the more, the better, and the higher the success rate.

The fourth is group reactive antibody (PRA): it is used to judge the immune status and sensitization degree of renal transplant recipients. No sensitization PRA = 0-10%, moderate sensitization PRA = 11-50%, high sensitization pra50%. The survival rate of transplanted kidney decreased in turn, that is, the smaller the sensitization, the better.

Next, we began to draw blood from the patient's three sons in turn.

Results in the first blood group, two sons were inconsistent, and only one was consistent.

"Strange, these two are not only inconsistent, but also impossible?" Guo Xiang got the test sheet and said.

"What's impossible?" Asked the man.

"This......" Guo Xiang glanced at the woman and then looked at the man. "Which two are these two?"

The man came up and looked, "these are my eldest and second sons. Can't they? Only the youngest son? "

"This..." Guo Xiang didn't dare to say, this blood type, the couple can't have such a blood type child at all. What can we do? Do you want to say?

Can't this woman steal her life when her husband goes to sea?

Well, Guo Xiang really doesn't know whether to say it or not.

The man saw that Guo Xiang was a little anxious. "Doctor, what do you want to say? Don't hide me!"

"Well..." Guo Xiang hesitated and said, "these two children don't seem to be yours. Your husband and wife can't give birth to children of such blood type."

"What?" The husband and wife were surprised, "impossible!"

"I'm from a medical point of view. You see, you have type B blood and your lover has type O blood. Logically, the children you two have can only be type B or type O, but these two children have type a blood, which is not in line with medical principles." Guo Xiang said.

The man's face changed greatly. He thought of something and suddenly turned to his wife, "Qian Fang, you, you take advantage of my absence..."

The man pointed at the woman, his hands trembled and couldn't speak.

"No, I don't!" The woman shouted, "I didn't do anything sorry for you, absolutely not."

"Doctor, is there a mistake? I didn't. how could I do that? It must be a mistake. Check it again!" The woman looked frightened.

Three children were also shocked. Two children were not born by their parents? How is that possible?
