Chinese and Italian medical "madmen" work together! The first human head replacement will be completed together

Publishdate:2019-08-29 Views:222

In April this year, Italian neurosurgeon expert segil cannaviro announced that he would complete the world's first "head transplant" operation within two years, and everyone was in a uproar. Yesterday, the "medical maniac" came to Harbin to visit his old friend Ren Xiaoping, a hand microsurgery expert from the second hospital of Harbin Medical University who has successfully completed the mouse brain transplantation and is currently challenging the monkey brain transplantation. The two will establish an international partnership to jointly complete the "head transplant" operation, which can be called a human miracle.

Two medical "madmen"

After the success of the operation, who is the "new man"? Is the memory still there?

"Head transplantation", if the head replacement surgery is successful, who is the brand-new person? Segil cannaviro said that the head, the head transplant is who, the body only as an organ transplant. After the successful transplantation of the head, the memory and original functions of the brain subject will be preserved. Even if the psychological and trauma influence the behavior habits, the "mental world" of the person will not be changed.

What is the chance of success?

Segil cannavillo thought that the world's first head transplant was like the first human landing on the moon. At that time, he said that the survival rate after landing on the moon was 50%, but he thought that if everything was ready, the success rate of the first head transplant would be 90%.

Problem 1 solved:

Central neuralgia is the most frequent postoperative complication after transplantation. If it is not solved, even if the head transplantation is successful, people will die of central neuralgia. At present, "medical maniacs" have developed methods and drugs to overcome this disease.

Problem 2 solved:

Traditional medicine holds that once the central nervous system is damaged, it cannot be recovered, and once the spine is broken, it will not regenerate. But medical fanatics have proposed that through a kind of spinal cord "adhesive" to regenerate it, the patients with high paraplegia can stand up again, and the central nerve connection in the head transplantation should be able to overcome, which is also the core research problem of Ren Xiaoping's continuous attempts to brain transplantation.

Problem 3 solved:

The medical fanatics believe that from the previous experiments, there will be no super rejection after head transplantation. The long-term and chronic rejection needs to be studied according to the specific situation.

The first patient will be a 30-year-old Russian scientist

Valery donov, a 30-year-old Russian computer scientist, was born with congenital muscular dystrophy, which worsens every year. He wanted to have a healthy body before he left the world. He had a fiancee. He wanted to live a normal life. So in April, he agreed to undergo a head transplant from segil cannaviro, becoming the first to eat crabs.

In May 1908, gusty, a doctor in Chicago, USA, carried out the first case of dog head transplantation with text and picture records. He cut off the head of one dog and transplanted it under the neck of the other, so that the dog had two heads. Unfortunately, after a few minutes, the dog's head stopped moving, and the transplant failed.

In the 1950s, dmikov, a Soviet scientist, succeeded in "manufacturing" a double headed dog by trying to transplant animal heads through surgery.

In 1956, Zhao Shijie of No.2 Affiliated Hospital of Harbin Medical University challenged the dog head transplantation, and the two dog heads survived for 5 days and 4 hours.

In 1970, Robert white, an American neurosurgeon, transplanted the head of a living macaque into another headless macaque. However, white was unable to connect the spinal cord of the two, resulting in the final paralysis of the monkey, which only survived for 8 days. In 2013, Ren Xiaoping's scientific research team of the second hospital of Harbin Medical University carried out the mouse experiment of the first brain transplantation. After the operation, the mice with the new brain began to breathe and recover their heartbeat, and survived for a period of time. And began to challenge the monkey's brain transplant.

In June 2013, Italian neuroscientist segil cannaviro published a paper in the International Journal of Neurosurgery, saying that the main obstacles of head transplantation have been overcome.

In April 2015, a 30-year-old Russian computer scientist who was born with muscular dystrophy volunteered to become the first person in the world to have a "head transplant". Italian neuroscientist segil cannaviro accepted his proposal and said the operation would be completed within two years. As for the news that the head transplantation will be completed within two years, segil cannaviro said that this time is not accurate. At present, there are still some difficulties to be solved and the specific time cannot be determined. However, he believed that in the next few years, various difficulties should be solved to complete the head transplantation.
