What are the scientific and technological breakthroughs behind the transplantation of pig hearts in

Introduction: American heart disease patients have received pig heart transplantation, which also allows netizens to see the development of science and technology. With the continuous changes of society and times, some people are also able to see advanced technology.

As a doctor, you must first think about your patients, so it is not easy for such a technique. <>

At that time, it was a 57-year-old heart disease patient, because he could not find a matching heart in the hospital, so he used pig heart for transplantation, and found that human genes matched pig heart very well. Many people don't pay attention to their diet in their lives, so as a patient with advanced heart disease, it is very good to have a chance of survival, but after having such technology, many people are also very shocked, and they did not expect that pig hearts can match the human body. There are many medical people who are constantly exploring and researching, and because of their contributions, everyone can see how powerful technology is.

No matter in **, the first thing to do is to protect your body, you can't eat what you can't eat, because this will also lead to the occurrence of some diseases, so like some people with heart disease If they can still live, then they also cherish their body very much, when you accept some genetically modified organisms, you must think about it clearly, think about whether you can do it. <>

The first reaction of most netizens when they saw such a thing was shock, in fact, this is also the first time that the heart of a genetically modified pig has been transplanted into a human heart, so it also allows you to witness the continuous progress of technology. If you like to smoke, you must quit your bad habits, take care of your body, and you must start from usual, don't wait until you have no way to recover, and then think about curing the disease, then it is too late at this time.

This transplant is the first to show that a genetically modified animal heart can function like a human heart when transplanted into a human body, and the body does not immediately reject the animal heart. The team will also continue to observe patients for some time to determine if xenotransplant technology can continue to work and save lives.

American heart disease patients have achieved pig heart transplantation, overcome cross-species organ transplantation, solve the immune rejection of pig organs in the human body, solve the spread of xenoviruses in the human body, and realize gene "knockout", knock out and human rejection genes, and prevent them from gene expression.

It has made breakthroughs in genetic science and technology, as well as surgical operations, transplantation technology, medical technology, and scientific and technological exploration and research.

The heart of a pig is relatively large, the heart of a human is relatively small, the blood vessels of a pig are more, the blood vessels of a person are less, the beating frequency of a pig is faster, and the beating frequency of a person is slower.

The biggest difference is that all the adipose tissue of people is yellow, while our common pork, cattle and sheep fat are white. Heart fat is no exception.

There is no difference between a pig's heart and a human heart, but it is not necessarily inside, and there may be some pig manifestations after transplanting a pig's heart.

There is no difference, because they are all mammals, and there is not much difference in the heart.

Introduction: Recently, we saw such news, that is, according to some ** news in the United States Today, we saw that a patient in the United States successfully transplanted the heart of a pig, which aroused the curiosity of many people. So what are the problems that every heart disease patient will face in the process of receiving a pig heart transplant?

Let's find out.

First, some problems faced

First of all, we know that this patient's current condition is relatively good, and his genes have also been modified during the surgical transplant process, so we will continue to observe, everything is in an unknown state. We all know that he still has hope after his heart transplant, he is still in the observation period, his heart disease is relatively serious, and it is in the advanced stage, he hopes that he can ** and be able to act after the transplant. We will find that the operation of this medical team is also relatively good, and through the research results of one more year may change the fate of many people, and their surgery is also a step forward in solving the shortage of organs, and saving more people through some xenotransplanted organs.

2. Overcome some difficult problems

We know that human organs and animal organs are very different, and it can be transplanted well in the human body, first of all, we must overcome some rejection functions, and there are also some virus excretions, so these are all things that need to be overcome. We can find that in this operation, it is not only a matter of technology, it is a major challenge, and when faced with these challenges, people are brave enough to solve it, and give hope to people, and also save more people. So you will find that this problem is relatively large, in the eyes of many people may be a successful and innovative initiative, but in the eyes of the doctor he may be a very difficult and effective task, through years of investigation and actual combat to have today's results, so everything is still unknown, continue to observe to find out whether this method is feasible, so everything is under observation, looking forward to better results.

The difficult problem is how to connect the pig heart with the human blood vessels, how to preserve the pig heart, whether it can be transplanted without barriers, and the adaptability of the heart and the acceptance capacity of the human body should be determined during the transplantation process.

To avoid rejection, pay attention to the connection of blood vessels, and also pay attention to the degree of matching. It is necessary to pay attention to avoid bacterial infection, and also to break through some key technical problems.

During the operation, I encountered the problem of rejection, because the heart of a pig is different from that of a human, and the blood vessels are very thick, so it is particularly difficult to suture.

The man is in good condition after surgery, but what the future holds, everything is still unknown, and experts also said that they can only observe further.

For every sick patient, ** is a very desirable thing, but not all diseases can **, only the doctor can do his best. In such a situation, doctors will continue to study according to their own specialties can be the best program, and for the transplantation of pig hearts into the human body, it is a very bold medical attempt, if successful, then it will represent the further development of human medical technology.

1. The world's first pig heart transplanted into the human body.

According to overseas ** reports, on January 10, a fifty-year-old man in the United States suffered from advanced heart disease, and heart transplantation was his only hope for survival, but we all know that it is very difficult to find a suitable organ source, especially when there are many patients who need organ transplants, and the organ inventory is even tighter. So, in the end, the man agreed to undergo a pig heart transplant, and the operation was finally completed after 7 hours. <>

Second, the man is in good condition after the operation, but what the future will be is still unknown.

According to the doctor who operated on the man, the heart was taken from a genetically modified pig, that is, modified. The man has woken up after receiving a pig heart transplant and is currently in good health, but doctors cannot guarantee that he will not have any health problems in the future, after all, this is the first heart transplant in the world. <>

3. What is your personal opinion?

Throughout the world, medical technology has advanced step by step, and there is no overnight success. Therefore, it is now a great step forward in the history of medicine to be able to transplant pig hearts, and if the man does not have other physical problems or minor problems in the future, I believe that such news will be more sensational around the world, and it will also represent a higher level for human beings to solve the problem of organ scarcity. So, I think we need to keep an eye on news like this and feel the miracle that comes from medicine.

The man's current condition is still very good, although the body has obvious rejection after the transplant, but under the treatment of the doctor, his current vital signs are relatively stable, and there is not much danger to life.

The man's current state is still very good, and he has done a good conditioning, his physical condition is also very perfect, he has received a good **, and his nutrition can keep up.

The man is in great shape because he's already through it and he's recovering, so I admire the local skills.

The man here is currently in good physical condition, there is no rejection at present, his vital signs are relatively stable, and there is no danger to his life for the time being.

The patient was transplanted with a pig heart, and the patient is currently in good condition and has not experienced any rejection. <>

I think this is a milestone in the development of the patient once the patient is determined not to have any rejection. Then it means that more and more people with heart disease will have hope of life and can survive. <>

This great feat came from Bartley Griffith, director of the Heart Transplant Program, whose patient was not qualified to transplant a human heart. Therefore, he came up with another transplantation option, which is to transplant the heart of a pig. In order to survive, the patient can only choose to accept it.

Luckily, he seemed to have made the right bet and he was recovering well after the surgery. <>

However, it should be clarified that the pig heart used this time is not an ordinary pig heart, but a pig heart that has been processed by genetically modified technology. Because many pig body parts have made outstanding contributions to human treatment, experts have once again put heart transplants on pigs' heads. Ready for experiments very early, pigs are waiting for someone to come and experiment.

This is not the first time that people have wanted to borrow animal hearts to save humans, and scientists have long wanted to use primate hearts to transplant them into humans. But unfortunately it failed in the end, and the baby who was transplanted with a heart died after only nine months of life. For a long time after this event, scientists were looking for suitable animal hearts for transplantation.

Pigs are the second test subject. <>

Personally, I hope that the result of this surgery will be a perfect success, that is, the life of the old man can continue to be extended, and there will be no rejection. Because in this way, many people with heart disease can have a chance to survive. Many people are looking forward to this outcome, especially those who have heart disease in their families and are desperate to find the right source of heart to help their families.

And once the pig heart can really adapt well in the human body, then the cost of heart transplantation will be reduced, and it will not be so expensive.

At present, the patient is in good condition, but this is the first time this heart transplant has been performed, and it is not known if there will be other adverse effects, but regardless of the future situation, it shows that science and technology are advancing.

At the moment the patient is in good condition, the pigs used in the transplant surgery have been genetically modified, but the rest of the situation is unknown, and we expect everything to get better.

At present, the operation has been successful, and the current condition is good, there are no complications, and we will continue to pay attention to the follow-up.

The completion of this operation has made a great breakthrough in organ transplantation technology, and the demand for organs in today's society is very large, and the success of this operation means that human beings will have access to endless organs or tissues, and a new era of medicine will come, which greatly encourages the confidence of the medical community and provides a good example for everyone.

In the United States, this surgery is of epoch-making significance for the clinical medicine industry. The difficulty of this surgery is very high, which is a boon for heart patients.

This technology has changed the fate of many people, further solved the crisis of organ shortages, and offered hope for a potential organ transplant in the future.

Introduction: From a medical point of view, this is also a very brave attempt. Because some relevant medical examinations and data evaluation must have been done before the transplant, although the patient passed away, it promoted the development of medicine from another point of view. <>

Probably most people felt a little sad when they saw the news, because Qinglu eventually passed away from this patient. But at this time, there are also some people who feel that from a medical point of view, this operation is also a very brave attempt. Because in this process, we have collected a lot of data, and at the same time, it has laid a certain foundation for the future development of medicine.

So this patient is very great, and it is because of his dedication that this operation can go smoothly. This surgery is also the first in the world, so it can be seen that scientists and patients have worked together. <>

I heard that many people also have a general understanding of this operation, because this patient's condition is very serious, but he can't wait for a suitable heart. So at this time, the researchers came up with a new method, which was to transplant pig hearts to patients. Some relevant studies and data evaluation were also done before the transplantation, and the data after the surgery were also very normal, and the patients did not have any other adverse reactions.

Although the man eventually left, his dedication also led to the development of medicine in the valley belt. Because in the process of surgery, it also brought new insights to scientists, and also provided them with some other ideas. <>

When most people saw this news, they felt a little incredulous. Because everyone didn't expect that pig hearts could be transplanted into human bodies, at this time, netizens also put forward some of their own ideas, and they thought that it could be replaced by the hearts of other animals. In response to this idea, the people concerned also made this choice, and the reason why everyone made such a choice is because the heart of a pig is similar to the heart of a human.

So researchers have been working in this direction, and at the same time want to find completely new methods.
