In the case of this patient, you say that the family did not understand the doctor's treatment plan and directly asked someone if they needed to donate bone marrow. Do you think that the parents are eager to donate for their child? You think too much. Doctors have watched too many ethical dramas in clinical practice.

You know, even if parents love their children very much, they need to make some plans for their children. For example, whether the parents need to pay for the subsequent medical expenses of the children, and how the parents can continue to support the children if the children become weak after the donation. These practical issues need to be carefully considered by normal parents before making a decision. Besides, everyone has a kind heart, and ordinary people will definitely have concerns for the donors. This is human nature.

These people know the benefits of bone marrow transplantation for patients, and they also know the risks of bone marrow transplantation for donors. As a result, those who are eager to ask doctors to perform bone marrow transplantation are obviously against human instinct and should be questioned. If you look more carefully, you will find that the marriage relationship in such families is generally unequal. The one who is eager to make up his mind must have made up his mind and wanted the other party to donate. Or he has thought of other people who can donate, and it is impossible for him/her to donate.

After the internal medicine students said this, several surgical students immediately understood what it meant.

"Who is so anxious to ask this? Is it the child's father or mother?" asked classmate Wei Shangquan.

"I don't think they feel they need to donate." Zhao Zhaowei and Zhang Desheng shook their heads.

"How do you know?"

"Do they need to make a phone call if they want to donate by themselves? They make phone calls after phone calls, all to mobilize their family members to come to the hospital for examination."

"Hey, do they know that if this donation is made, and the child has no brothers or sisters, the parents and the child have the highest chance of being a successful match, maybe 50%."

...

...

"Do you think they don't know? They know their blood type is different from this child's. So they think they won't be the first to line up."

Student Wei touched his chest and said, "I think about this matter——"

"You don't have to worry." The two internal medicine students said worriedly to the surgical students, "We can foresee that this family will definitely quarrel in the hospital next."

Pan Shihua couldn't help but interject a scientific remark: "You should educate the parents in advance that hematopoietic stem cell matching is not based on blood type."

The official name of bone marrow transplantation has now been changed to hematopoietic stem cell transplantation. According to the source, it can be divided into bone marrow transplantation, peripheral blood hematopoietic stem cell transplantation and umbilical cord blood transplantation. Bone marrow transplantation has become a type of hematopoietic stem cell transplantation. It's just that the people are used to it and can't change it for the time being, and continue to call it bone marrow transplantation. From the beginning, hematopoietic stem cell transplantation was only bone marrow transplantation. Matching was not based on blood type, but mainly on white blood cell antigen HLA.

As mentioned before, the most feared thing about transplantation is rejection. Rejection is the natural attack of the human immune system on foreign matter that enters the human body. Since the human immune system is not very smart, it can only analyze whether it is a foreign body or not, but cannot analyze whether the foreign body is good or bad, and will attack all foreign bodies indiscriminately. Because of this, whether it is a disease or a doctor who wants to implant a foreign body into the human body, the human immune system must first recognize the foreign body. HLA can be regarded as one of the main signs for the human immune system to determine whether it is a self-reliant person.
