I can extract side effects

The causes of human death have always been complex. Wars, famines, murders, accidents, and even malnutrition in ancient times were also major causes.

However, after stepping into a modern society with great material abundance and peace and stability, the life span of human beings has been greatly extended, and the average life expectancy has increased to seventy or eighty years old.

In this way, the cause of death begins to become simpler.

Two major causes: disease and aging.

Whether it is disease or aging, it will damage the cells of the human body, causing some organs to begin to fail, which will affect the normal functioning of the entire body and eventually lead to death.

Yes, organ failure has become the biggest cause of death.

Whether it is a systemic infection or natural aging, it starts with the failure of each organ and inevitably leads to death.

So, what if the organ goes on strike and is replaced with a functioning organ.

Wouldn't it be able to greatly alleviate the death of people.

Because of this, organ transplantation has become the most direct way to extend life in modern medicine, and is hailed as one of the greatest medical miracles of the 20th century.

Even the concept of "death" has received a major shock.

In the past, people used to regard the permanent cessation of breathing and heart function as the sign of death.

However, due to the advancement of medical technology, the popularization of cardiopulmonary resuscitation, extracorporeal membrane lung (ECMO) and other technologies, some new problems have arisen, refreshing the human understanding of death.

Because even if the whole brain function stops, after the spontaneous breathing stops, the patient can still rely on measures such as artificial respiration to maintain the blood circulation of the whole body and the functional activities of all organs except the brain for a certain period of time.

This leads to the abnormal phenomenon of "living body, dead brain".

As we all know, the brain is the commander-in-chief of the body and an indispensable organ for human survival. Once the function of the brain ceases permanently, the individual's life will end.

Therefore, under such circumstances, the concept of "brain death" is gradually accepted by people.

The medical community directly revised the definition of death, and judged the irreversible permanent cessation of brain function, that is, the death of the brain stem within 12 hours, as death.

The biggest reason is that human brains cannot be transplanted at present.

Other organs that can be transplanted or replaced with artificial devices are not included in the definition of death.

And organ transplantation, a clinical method that can change life against the sky, has indeed become a means of prolonging the life of the top rich.

The third-generation head of the Rockefeller family found that his physical fitness was not as good as before at the age of 61. In order to control the money empire and continue his bright life, he has performed 6 heart transplants and 2 kidney transplants since then. transplant surgery.

Brutely adopting the most direct method of life extension, organ transplantation, he managed to live to 101 years old.

He even successfully completed the sixth heart transplant at the age of 99. He used a healthy heart that ordinary patients could not wait for, and he used it whenever he wanted, just to live for two more years.

Since the invention of organ transplantation in the 1950s, millions of people have been saved and given a second life.

Up to now, various human organs including heart, intestine, kidney, liver, lung, trachea, spleen, pancreas, retina and skin have been successfully transplanted, which can be described as immeasurable merit.

After organ transplantation, if the immune rejection is well controlled, most people can live for 5-10 years, and if they are in good health, those with less rejection can even live for decades.

Of course, if there is a strong rejection reaction between the donor organ and the recipient, the possible survival time is very short, usually only one or two years.

Therefore, organ transplant patients basically have to take immunosuppressants for life after surgery to prolong their survival.

All in all, although the life span of organ transplantation is limited, the comfort and happiness brought to patients and family members after the operation is unlimited.

However, due to the severe shortage of donor organs, transplantable organs are extremely scarce in the medical market.

Coupled with the existence of a series of problems such as rejection, ethics and morality, organ transplantation has never been popularized, and the lives saved are limited.

Scientists are currently solving this century-old problem. Autologous stem cell cloning of organs, gene-edited xenogeneic organ transplantation, etc. have all begun to make some staged progress, providing new ideas for the development of organ transplantation.

And this is exactly what Wei Kang thought of.

Sanqing has the most cutting-edge biomedical technology in the world, and it is absolutely possible to make rapid progress and make breakthroughs in this field.

He believes that one day human beings will be able to realize the technology of "replacing what is broken" and prolong life for a long time through organ transplantation.

And he has the confidence that the first person to realize this technology is definitely Sanqing.

Even if you can't replace all the organs in your body, you can at least replace one.

Even if the brain cannot be transplanted, it still restricts the length of human lifespan, but it is absolutely no problem to live to the end of life.

That way everyone can at least live to be over 100 years old in good health.

The realization of this achievement is definitely a human medical miracle of bringing the dead back to life, and it can meet the upgrade requirements of the system.

After confirming, he put away the system panel.

The panel suddenly turned into colorful light and disappeared.

Then, what appeared in front of him was a very familiar golden USB flash drive.

"It's probably the information of the 7 medical devices redeemed by the points."

"There are a lot of things this time, so I just stuffed the data into the USB drive."

Wei Kang thought to himself, he couldn't help but recall that when the AI ​​pharmaceutical system was upgraded last time, it was also because of too much data that the system directly manifested a USB flash drive.

He quickly picked it up and plugged it into his laptop.

A golden light flashed again, and the U disk turned into stars and dissipated in the air.

When I opened the desktop, I saw a newly created folder. I clicked it in and looked at it. It was classified into categories, and it contained detailed technical information of these seven devices.

Immediately he looked up to the sky and laughed loudly: "Haha, I got it! This time punching Johnson and kicking Pfizer, it will definitely work."

The next thing is very simple, the ability to hold money, of course, is to recruit troops first.

In the past, there were only two products in the equipment department. Although a lot of people were recruited, it was far from enough for a dedicated R\u0026D center.

There are tens of thousands of people in the major laboratories of the Pangu Research Institute, and only a few hundred people in the equipment department.

High-end medical equipment has a very high technical content and is an interdisciplinary subject that integrates medicine, biology, mechanics, materials, machinery, electronics, software and other fields.

There are not only high-end technologies such as CT, color Doppler ultrasound, artificial organs, and even brain-computer interface, but also low-end products such as orthopedic consumables, detection boxes, stethoscopes, and tongue depressors.

In short, the threshold is very low, but the ceiling is also very high.

This industry is also a typical talent-intensive and technology-intensive industry, with a long R\u0026D cycle and no less difficulty than aerospace.

Several major foreign medical device companies, such as GSP, not only have technology, talents, and capital, but also have advantages in a complete industrial chain from upstream material research and development to downstream industrial applications.

From these aspects, Sanqing can only be regarded as a novice player who has just started.

So he plans to recruit a group of high-end R\u0026D teams first, and is determined to build a world's most cutting-edge medical device R\u0026D center.

These products in his hands have high technological content. As long as his employees have a thorough understanding of reverse research and development, they will naturally continue to innovate and have independent research and development capabilities like a medical laboratory.

In addition to frantically recruiting equipment talents, he did not forget to find Tang Que and ask him to open a new professional laboratory for stem cell technology.

Stem cell technology does not actually refer to the embryonic stem cells of the rotten street. Even beauty parlors dare to use it to bluff people. "Regenerative medicine" and "stem cell beauty" are all deceitful.

The cutting-edge stem cell technology in today's medicine refers specifically to "induced pluripotent stem cells" (iPS stem cells). This discovery won the Nobel Prize in 2012. It belongs to the third largest biological science after cloning technology and genetic engineering in modern biotechnology. Achievement.

Scientists inject specific genes into human skin cells, successfully transform them into pluripotent stem cells, and differentiate them into embryonic stem cells through special means.

This technology does not use embryonic cells or egg cells, so there is no ethical issue. It can be controlled by gene combination, known as universal cells, and can eventually grow into human tissues or organs.

It can even cross the sex divide and differentiate directly into germ cells.

That is to say, a man can buckle a piece of foot skin, then transform it into iPS stem cells, and finally differentiate into eggs.

It is also possible to use the skin debris of a woman to differentiate into sperm through iPS stem cells.

It can even be differentiated into embryonic cells for self-cloning.

As for the differentiation into hematopoietic stem cells, which greatly reduces immune rejection and benefits bone marrow transplant patients, let alone.

In short, the emergence of this technology has great potential value in clinical treatment and has aroused strong repercussions in various biomedical fields.

Tang Que naturally understood this technique, and was taken aback when he heard the boss's thoughts.

"iPS stem cell laboratory?"

"Self-cloning organ research?"

He slapped his thigh and said with joy: "Great, boss, are we finally going to do some real technical work?"

"I've always been interested in research in this area, but I'm not an expert in this area because I specialize in it."

"Boss, I solemnly recommend a master to you. It just so happens that I have a younger brother who has just finished his Ph.D. in Biology from Eagle State University, and wants to find a promising job when he returns home."

"I'm about to recruit him, but I'm afraid that if the company doesn't engage in this business, it will delay others."

"Of course it's all right now, I'll call him as soon as I go out."

Tang Que said happily: "My junior brother is a genius. He is good at everything, but he is proud of his talents and has a bit of a wild personality. I am afraid that he will not be able to stand the atmosphere when he goes to college. The company is more relaxed. It is best to come to Sanqing. "

"When he was at the University of Pennsylvania, his teacher was Professor Thomson, the father of human embryonic stem cells, and Mr. Yu, the co-inventor of iPS stem cells, was also his senior sister."

He eloquently told all about his junior brother, which aroused Wei Kang's curiosity instantly.

"No problem, you have to check the recruitment. Now there are a lot of talents returning from overseas. HR said that there are too many people submitting resumes every day, even foreigners, and they are too busy."

"However, there are still few real geniuses. Unless there are departments that are particularly short of talents in Sanqing, they would rather be short than excessive, so I have not let go of the quota."

"You also know that the company still gives preferential treatment to real talents, and the atmosphere here is also very relaxed. I believe it is still very attractive."

Wei Kang laughed and said: "Personality is not a problem at all. Besides, no matter how crazy you are, can you still be crazy about Aaron?"

An imperceptible embarrassment flashed in Tang Que's eyes: "Well, my junior brother, he belongs to that special type, and you will know when you see him, but I can guarantee that there will be absolutely no technical problems."

Wei Kang nodded with satisfaction: "Okay, then I can rest assured."

"By the way, what's his name?"

"Ding Mian."

I was really sleepy last night, and I fell asleep while coding. I got up at 5:00 in the morning, and quickly finished coding and posted it. The remaining chapter will be added later.
