Chapter 889 Red And Yellow B1 Marrow
When the three of them were washing their hands, they discussed the process of bone marrow transplantation and mentioned the relationship between Zeng Xi and Zeng Zhuo.
Fatty: "I heard that Zeng Xi has a bad relationship with her parents."
"She has been a left-behind child since she was a child and has no relationship with her parents. She originally refused to donate bone marrow, but she agreed to it again."
Xia Xia faintly said: "I guess what the parents did."
"These parents prefer sons to daughters, and they hurt their daughters." The fat man complained: "If it were me, I might not donate."
After chatting for a while, the three raised their hands and entered the operating room.
now.
Zeng Zhuo was already lying on the operating table.
Not yet anesthetized.
Putting on sterile gloves, Xia Xia walked over to Zeng Zhuo and asked.
"nervous?"
Zeng Zhuo's face was pale, in addition to the morbid Bai, there was also a nervous look.
"My sister, does my sister agree?"
Xia Tian nodded: "Agreed."
"Hey……"
Zeng Zhuo sighed deeply: "Actually, she doesn't want to agree. Although she didn't say it, I can see it."
"She hasn't complained for so many years, but she actually resents her parents."
"I can only wait for me to get better, and then make up for her."
The three looked at each other, Xia Xia called the anesthesiologist and gave Zeng Zhuo general anesthesia.
After Zeng Zhuo fell into a deep sleep, the three continued to chat.
Fatty said, "Did his parents do HLA matching?"
Xia Tian nodded: "I did."
"Only sister matches him."
(HLA: Human Leukocyte Antigen, HLA is the product of the gene cluster encoding the major histocompatibility complex (MHC) in humans.)
The human body has a strong genetic code.
There are some people who use a common code, and people with the same HLA can get a bone marrow transplant.
HLA is an upgraded version of blood type!
Some people with different blood types but the same HLA can also undergo bone marrow transplantation. When extracting hematopoietic stem cells, the blood type is removed, leaving only hematopoietic stem cells.
before bone marrow transplantation.
Patients need radiation therapy to kill malignant cells in the body, as well as mutated cells in the bone marrow.
Brief overview: Kill the garbage in the body and replace it with healthy hematopoietic stem cells, and the patient can regenerate.
After anesthesia, wait for two minutes.
Xia Xia said: "The operation begins."
"Fat man, prepare to extract bone marrow."
Step 1: Drain the bone marrow from the patient.
If a person is compared to a big tree, then the bone marrow and hematopoietic stem cells are the part of the tree that absorbs nutrients and transports nutrients to the whole body. Once there is a problem with the hematopoietic stem cells, the delivered nutrients cannot be supplied to the body.
In the end, it can only gradually disappear.
Before treatment, all bad cells need to be drained.
Since it's not strong, then roll the ball!
Hematopoietic stem cells: ┭┮﹏┭┮crying!
Extracting bone marrow is very troublesome.
Take 1-2 cm of the anterior superior iliac spine as the puncture point.
The anterior superior iliac spine is commonly known as the crotch.
The bone marrow puncture needle fixator is fixed at an appropriate length (about 1.5cm for iliac puncture, which can be appropriately lengthened for obese patients, and about 1.0cm for sternum puncture).
Use the thumb and index finger of the left hand to fix the skin at the puncture site, and hold the needle in the right to puncture the bone surface vertically.
When the needle touches the bone, it stops.
At this time, it is necessary to rotate left and right to pierce the bone slowly. When the resistance disappears and the puncture needle is fixed in the bone, it means that it has entered the bone marrow cavity.
This step is operated by Han Meiji.
She is more experienced.
This process is very slow.
Bone is very hard. If it is too hard, it will pierce. If it is too light, it cannot be pierced. It is equivalent to taking a needle to pierce the bone. It needs to keep turning the needle to pierce the bone bit by bit.
The whole process lasted half an hour.
Han Meiji was sweating profusely.
"Let me do it."
Xia Xia was ready to take over. At the same time, he said to the system: "Little baby, turn on the perspective."
【OK. 】
[Perspective has been opened. 】
Because it is impossible to know the thickness of the bones, so be very careful when stabbing, once you can see how thick the bones are left with the naked eye, it will be easy.
Han Meiji has already drilled halfway.
Check it out.
The bones are very thick.
And it is hard, and it took a little effort in summer.
8 minutes later.
With a small 'puff' sound, the needle entered the bone marrow cavity smoothly.
in perspective.
It can be seen that only one-third of the patient's bone marrow cavity is red bone marrow, and the remaining two-thirds of the bone marrow has turned yellow.
Bone marrow color: red.
Red bone marrow, with hematopoietic function.
The yellow bone marrow is the old red bone marrow, which has lost its hematopoietic ability and becomes fat remaining in the bone marrow cavity.
Newborn babies are all red marrow.
This shows that the hematopoietic ability of bone marrow is very strong. As the age increases, the proportion of red bone marrow begins to decrease, especially in patients with disease, the yellow bone marrow will gradually increase.
Zeng Zhuo is young, when his vitality is strong, the red marrow in his body should occupy four-fifths.
But now.
Only a third of the red marrow remains.
If the fluoroscopic eye can be enlarged, it can be found that his hematopoietic stem cells should be deformed.
Such red marrow can no longer deliver healthy blood to the body.
Once the blood in the human body is less than 70%, it will reach the limit of life, fainting, shock, and even death at any time.
The only way.
Only hematopoietic stem cells can be replaced.
"Bone marrow extraction now."
The needle is left in the bone marrow cavity and the bone marrow is drawn from the body.
The blood of the human body is about 4000ml, and the bone marrow is only 1000ml.
1000ml doesn't seem to be much, but two sips of beer can be boring.
But extracting it is troublesome.
The whole process needs to be very slow.
An hour has passed.
Extract 300ml.
The summer speeds up slightly.
two hours later.
Extract 700ml.
The yellow marrow was extracted.
Han Meiji frowned and said, "The marrow in his body has been fattened, and there is too little red marrow. This little bit of red marrow can no longer support his body."
Summer nodded: "Yes."
"A bone marrow transplant is his only hope."
"Fat man, go and ask the laboratory to prepare the hematopoietic stem cells, which can be extracted in about an hour."
Donors need to provide blood in the laboratory, and then the laboratory extracts hematopoietic stem cells and injects them into the patient. When the operation began, Zeng Xi had already gone to the laboratory.
"it is good."
The fat man took off his gloves and left the operating room.
10 minutes later.
The fat man ran back in a panic.
"It's not good, Brother Tian, the donor..."
"Donors regret it."
"She's not donating anymore!"
