The history of blood transfusions began as early as 1667, when a French nobleman transfused 280 ml of calf blood to a mentally abnormal homeless man in an attempt to treat his mental problems.

This hapless patient experienced a severe immune response, and after wandering around the ghost gate several times, he miraculously survived and maintained a period of peace.

As a result, the medical community began to accept blood transfusion therapy.

In the following three hundred years, blood transfusion is still in the process of exploration, because there is no knowledge of blood type, so during this period, blood transfusion is to draw a bag of blood into it, as for whether you can survive or not, it all depends on luck.

It was not until 1912 that the French created vascular anastomosis, for which they were awarded the Nobel Prize.

But it was the Viennese pathologist who really made blood transfusion a scientific and effective treatment, who discovered the law of ABO blood group coagulation in 1901, so this old brother also won the Nobel Prize in 1930.

From this, we can conclude that the crooked kernel who has always paid attention to human rights is actually the one who pays the least attention to human rights.

Or rather, they never cared about the human rights of anyone but themselves, as well as the aristocracy.

Imagine a normal person, how can he be so mad as to transfuse cow blood into the human body for testing? And the one who lost was a mentally abnormal homeless man? If it was a normal person, I'm afraid I would have killed that thing a long time ago.

Fortunately, Li Yuanji knew that there was such a thing as a blood type, so he didn't rashly find some blood and give it to Zhang Gongjin, otherwise, he would have a high chance of dying, and he would die very miserably.

And the final result was that among the six people in the entire hall, only one imperial doctor had the same blood type as Zhang Gongjin.

So, Li Yuanji called the guards outside one by one to come in for a bloodletting test, and after a short time, he found four guards with the same blood type.

If it weren't for Zhang Gongjin's face that had begun to turn pale, Li Yuanji would really want to test a few more, but fortunately, four people were barely enough, and if it was really not enough, he could continue to test in the future.

"Is Your Majesty trying to transfuse someone else's blood directly into Zhang Dudu's body?" An imperial doctor was surprised, he finally realized what Li Yuanji wanted to do?

Theoretically, this seems to be possible, but is it really possible? Who knows?

Besides, who is Zhang Gongjin? A term of the Metropolitan Governor, how can he be regarded as a high-level of Datang, right? What if something goes wrong?

"Your Majesty, by all means, this matter has not been verified, in case of mistakes, the consequences will be ......" Another imperial doctor also hurriedly dissuaded, not cowardly, in fact, they also thought of this possibility, but before treatment, they need to experiment, test on others.

It can be an animal, it can be a human, but it must not be Zhang Gongjin, it is those officials of the Tang Dynasty, who will kill people......

"A bowl of river water and a bowl of well water are mixed together, a bowl of river water and a bowl of sea water are mixed together, a bowl of sea water and well water are mixed together, and the problem will definitely arise, but two bowls of the same water mixed together, the probability of problems is not large, and this is the most effective solution." Li Yuanji explained lightly, he couldn't come up with those scientific arguments to convince them, so he could only use this kind of seemingly reasonable words to say it, as for the effect......

"Your Majesty, the minister also feels that this matter is inappropriate, although Hongshen has been unwell recently, but it should be no problem in a short time, the minister suggests that His Majesty order the imperial doctor to find some similar patients for testing, and then promote it after confirming that it is correct." Xiao Yu also felt that something was wrong with this.

After all, this is already an experimental nature, and the previous experiment was purely an experiment, and if it failed, it failed, and it would be good to come again, but this time it was an experiment on people, and it was not an ordinary person.

If he didn't stop it today, if something went wrong, Xiao Yu felt that he would definitely take the blame.

Li Yuanji had a headache, and no one supported him to conduct the experiment directly.

And this so-called experiment, in fact, Li Yuanji has minimized the risk.

The risk of blood transfusion is due to rejection problems, or hemolysis problems, but the reason for this result is because of the difference in blood type between the two or the patient's special physical problem.

If the blood type is the same, although the rejection problem still exists, most of the time it can be carried over, and the pain is only short-lived, and the probability of a dead person in this situation is probably lower than the probability of 1 in 10,000.

But what can I say about this? Directly say no problem, do it, Lao Tie, if something goes wrong, I'm responsible?

Joke......

The reason why he is so anxious is that he is worried that Zhang Gongjin will not be able to hold on, or that the illness will be more and more serious, delaying the time for treatment.

Ischemia in the body can be regarded as a large platform, and those diseases can be regarded as objects placed on the platform, and the platform itself is not good, so how to repair those objects?

"The minister's life is the life, the people's life is also the life, the minister does not think that the minister's life is much more precious than the people's life, and today's minister, there is only this scumbag body left, if it can bring the gospel to the world, what if the minister goes? I beg your Majesty's permission to take this first step. Zhang Gongjin didn't have much worry, but straightened his waist frankly and said.

If it weren't for the pale face and the whole person looking sickly, these words must have been very imposing.

is still the same sentence, his body knows that he originally planned to hold on until the change of office, but this time Li Yuanji Zhao returned to the dynasty to report on his work, and Zhang Gongjin thought about resigning when he was on the way.

What about being in a high position? It's nothing more than a life-and-death parting.

As early as when he was in Xiangzhou, he asked someone to see it, and he knew his condition very well, so Zhang Gongjin knew that he didn't have much time left, so he had nothing to be afraid of.

And this experiment, if it can be successful, it will inevitably be able to write a grand stroke in history, if it can't succeed, it is nothing more than dying some time early, but it can also provide an experience for future generations, maybe it can also stay in the last stroke in history.

For Zhang Gongjin, this experiment does not seem to be a bad thing, and he has no choice, which is the most important thing.

"Let's go back and rest for three days, eat as much supplementary food as possible, and carry out blood transfusions after three days, and the four soldiers who were able to fuse before, they don't need to be on duty these days, arrange for them to rest for a few days." Li Yuanji arranged the whole thing.

Although they know that there is no danger, they still have to give them some time to prepare.

Of course, the imperial doctor also needs to prepare equipment for blood transfusion.

Hollow needles, this is not difficult, but for them who have never been in contact with the whole process, they are still busy with this matter.

As for the four soldiers, Li Yuanji also personally appeased them, and told them that the blood draw was not as terrifying as imagined, and the four people did not draw blood at the same time, each person only drew half a bowl of blood at most, and only once.

As a veteran who has been on the battlefield, this can be regarded as a relief, half a bowl of blood will not kill, for them, this half bowl of blood does not feel at all.

But before that, Li Yuanji still arranged for the imperial doctor to conduct a comprehensive examination of the four of them, and they must ensure that they are strong, and secondly, they must ensure that they have not suffered any symptoms within three months, so as not to bring germs into Zhang Gongjin's body and cause accidents.

A series of preparations are being carried out intensively.

And Zhang Gongjin, who left the Taiji Palace, came to the tea house again that night, and it was still those people.

"What? Your Majesty wants to give you a blood transfusion? Fang Xuanling was stunned, what is this? It's obviously going to resign, okay? As a result, the resignation was not mentioned at all, but blood transfusion was mentioned?

Besides, does Li Yuanji have any research in medicine?

Even those imperial doctors have no way to deal with the disease, what can he do? If there really is, then why not treat Qin Qiong?

Of course, they would never have thought that not treating Qin Qiong was not because of anything else, but because they didn't expect it.

Qin Qiong had long since faded out of everyone's sight, and stayed in Zhuangzi on the outskirts of Chang'an all day.

At first, he often stayed there because Taipingfang was heated, but after Taipingfang was developed, the flow of people was too large and too lively, which was not conducive to his recuperation, so he moved to Zhuangzi outside the city and built several heating rooms.

Of course, as time goes by, Qin Qiong's physical condition is getting worse and worse.

He suffered too many injuries in his early years and lost too much blood, which led to his lack of hematopoietic ability, and he couldn't make up for the lost blood after so many years of resting, and as he aged, his physique also had problems.

Although Qin Qiong looks more fragile than Zhang Gongjin now, in fact, if you compare the two, you will find that Zhang Gongjin, who looks better on the surface, is in a worse situation.

"Yes, today the old man submitted his resignation due to physical discomfort, and His Majesty immediately called the imperial doctor to check on the spot, and when the imperial doctor said the old man's problem, His Majesty said that blood transfusion can solve some problems...... "Zhang Gongjin did not hide it, and even Li Yuanji personally said the matter of the blood test.

This result surprised everyone, everyone is not stupid, there are some things, they don't need Zhang Gongjin to say too clearly, they also know how to judge in their hearts.

"Then you agree? What if something goes wrong? Xiao Yu, that old horseman, didn't persuade His Majesty? Zhang Xingcheng said a little angrily, this is not a trivial matter, how can it be so reckless?

"Persuade! But the old man did not agree! Zhang Gongjin glanced at these people who did it again, they are all old ministers of the Qin Palace, although they have voted for Li Yuanji over the years, but they also go to sweep Li Shimin's tomb from time to time, talking, from another level, they are still in a camp now, but Li Shimin is no longer there, so they chose to think about the Tang Dynasty, otherwise, they would rather follow Li Shimin to rebel than be like now.

Although it turns out that Li Yuanji is indeed more suitable to be the emperor, they are the ones who follow Li Shimin to fight the country together.

If you want to blame, you can only blame Li Shimin for dying too quickly, so that he died before they could react, and if you want to blame, blame Cheng Zhijie for rebelling, but Li Shimin didn't notice it, and they didn't notice it.

But they can't blame anyone, because judging from the results, only in this way can more bloodshed be avoided, and if you want to blame, blame Li Shimin at the beginning, who softened his heart for a while.

"It's not a secret, the old man is not long in life, and he has the idea of resigning when he returns to the dynasty this time, so it's okay, at least he can do another good thing for the people of the world before he dies, although I don't know if it's good or ......bad."
