Physician of the Song Dynasty: Zhang Kai and Li Qingzhao have a private life-long contract

Ten thousand guan!

Fifty thousand dollars!

One hundred thousand coins!

…………

Led by doctors, more and more wealthy households began to buy national bonds! National debt gradually became popular in Kaifeng.

Cautious people would rather buy low-interest one-year treasury bonds of three percent to reduce risks, while bold people directly buy five-percent treasury bonds with a maturity of three to five years, and smart people mix short-term treasury bonds and long-term treasury bonds. purchase.

In just one month, 1.2 million treasury bonds were sold, of course half of which was contributed by doctors.

Because of Fan Zheng's medical guarantee, most of the doctors in the world bought the five-year treasury bonds with the highest interest rates. What's more, some of their relatives and friends bought them in the name of the doctor in order to get the medical guarantee. In this regard, Fan The rule is to turn a blind eye.

Now for the first time, doctors are still needed as guarantees. Once the national debt is cashed as scheduled, doctors will not be needed at all, and they may have been sold out long ago.

When Fan Zheng handed over the money of 1.2 million guan to the Ministry of Household Affairs, the whole court was shocked.

"We sold 1.2 million guan in one month. In this way, it is not difficult to sell out all 5 million treasury bonds." Fan Chunchuan exclaimed.

Although his nephew has never given the Fan family peace of mind, every time he does something, people are constantly surprised.

Fan Zheng said proudly: "Only 1.2 million bonds were sold in January, or because this was the first issuance of national debt, and the people had doubts. When the court pays the one-year national debt a year later, the credibility of the national debt will be If verified, these 5 million treasury bonds will probably be sold out in less than a month."

In later generations, the creditworthiness of national bonds will be so great that they will be sold out if they are not available for one day, let alone one month.

Fan Chunchun couldn't help but show a hint of joy. With the wonderful plan of national debt, the court no longer had to be stretched when it was in urgent need of money.

"However, my nephew would like to warn my fourth uncle that the biggest reliance on the national debt is the credit of the court. Once the court defaults and cannot pay on time, the credit of the national debt will completely collapse. If the court wants to issue bonds in the future, I am afraid no one will believe it anymore. "

Fan Zheng warned.

He did this to prevent the imperial court from printing indiscriminately like Jiaozi. If one day, the imperial court fails to pay the money, such a good policy will turn into a policy that will harm the country and the people.

"Don't worry, Zheng'er, fourth uncle understands!"

Fan Chunchuan nodded solemnly. Among the people, if a person borrows money and fails to repay it, his reputation will be completely ruined, and no one will be willing to lend him money anymore.

This is true for the people, and even more so for the court. The court even values ​​credibility more than the people.

Fan Zheng couldn't help but nodded slightly as he watched 1.2 million yuan being escorted into the Ministry of Civil Affairs.

For a country, money is blood, and the national debt is just an alternative application of doctors’ blood transfusion therapy.

No! National debt is simpler than blood transfusion therapy.

Human blood needs to be identified before it can be imported, but money does not need to be identified, and all comers are welcome.

"Fan Taicheng is very happy. Doctor Pang has discovered the mystery of blood!" Suddenly, a Hanlin medical officer came to report excitedly.

"Pang Jizu!"

Fan Zheng couldn't help but be stunned.

After he made the glass, he asked Gongsu Ying to build five sets of microscopes and give them to Qian Yi, Yang Jie, Su Dun, Pang Jizu, and Zhang Youniang, one for each of them, and the corresponding blood transfusion tools. He did not expect to be the first to verify the bleeding type. Turns out to be a veterinarian.

Medical Officer Hanlin nodded with a strange expression.

The Traditional Chinese Medicine Hospital and Tai Hospital tried their best to compete in blood transfusion therapy, but they did not expect that the first to succeed would be the humble veterinarians.

In the Imperial Medical Office,

Doctors gathered together again! And Pang Jizu, who is a veterinarian, has become a well-deserved focus.

"After Brother Fan sent the microscope, Pang continuously drew blood from various animals for research, but found nothing." Pang Jizu said.

Yang Jie couldn't help but smile bitterly. He touched the needle on his arm and felt the pain. He couldn't help but smile bitterly. He was not the same. He even used his own blood to study it, but also found nothing.

"Pang paired and mixed hundreds of horse bloods one by one, observed them under a microscope, and finally made a discovery. There was no abnormality in the fusion of some horse blood. Fan concluded that the two horses had the same blood type and could be transfused. The blood from other horses fused together and showed clots on the microscope.”

Qian Yi, Yang Jie, and Su Dun nodded slightly. They had also discovered this phenomenon before, but they didn't pay attention to it, thinking it was a normal phenomenon. After all, blood would condense over time.

"So, Pang classified the blood types of the horses and used the eliminated old horses to conduct blood transfusion experiments. The result was a total of four blood types! A, B, and C." Pang Jizu said.

Su Dun wondered: "Aren't there four types? Why are there only A, B, and C?"

Pang Jizu explained that the four types are: A, B, C, and A and B. There is no problem with blood transfusions between the same blood types. However, what is interesting is that blood type C can be transfused with the other three blood types. He is the only one. Du can only receive blood transfusions of the same blood type. Blood types A and B can receive blood transfusions from three blood types. However, he can only give blood transfusions of the same blood type. He has two blood types, A and B. He can give blood transfusions to A and B and the same blood type. "

"Is that so?"

The doctors couldn't help but were in an uproar. They had never thought that blood transfusions would include blood types. No wonder there would be deaths from blood transfusions.

Pang Jizu nodded and said: "It should also be noted that the blood transfusion must be a healthy person, and blood transfusion is not allowed between immediate family members."

This is a painful lesson he learned after spending a lot of time.

At that moment, a group of doctors couldn't wait and immediately took their own blood to start research. Sure enough, they found that human blood types are the same as horse blood types, and they also have four blood types: A, B, and C.

Fan Zheng couldn't help but sigh. Pang Jizu was both talented and extremely lucky. The blood types of horses and humans were almost the same. He happened to be in charge of horse affairs recently. He was the first to get the moon first, and he was the first to figure out the mystery of blood types!

"Dr. Pang used horse blood to complete the blood transfusion experiment. It can be seen that the veterinarian lineage is of great use to medical research. From now on, all medical experiments must be tested on animals first. After success, they can be applied to humans." Fan Zheng said solemnly.

"As ordered!"

All the doctors nodded.

Although doctors have a life-and-death contract to avoid risks, causing death will damage medical ethics and reputation. If experiments can be carried out on animals, doctors can avoid a lot of risks.

"Fan Taicheng, the female doctor wants to apply blood transfusion therapy in obstetrics." Zhang Youniang said impatiently.

What is in urgent need of blood transfusion therapy is not the surgical lineage that masters Hua Tuo's unique skills, but the obstetrics and gynecology department of female doctors. Postpartum hemorrhage is one of the most common headaches and stubborn diseases in obstetrics and gynecology, and many women have died from it. If blood transfusion therapy is used , I am afraid it will save many mothers.

"You can give it a try! However, you must inform us in advance and sign a life and death contract." Fan Zheng said solemnly.

"I understand!" Zhang Youniang said, forcing herself to hold back her excitement.

"Blood transfusion is easy! The biggest problem now is the source of blood!" Qian Yi frowned.

Blood transfusion therapy naturally requires fresh blood. In this era, people believe that blood is the essence of the human body, and blood loss will shorten one's life.
