Genius to remember the address of this site in one second: []The fastest update! No ads! Just when everyone's gift giving event this year should end here, I didn't expect that a special promotional video made everyone who was excitedly discussing quiet again.

The promotional video tells a story about a firefighter who unfortunately encountered a deflagration while participating in a major fire search and rescue process, which eventually resulted in 70% of the firefighter's body being severely burned.

Although rescued, the firefighter was out of danger and returned to health. The disfigurement caused by the burns on the body will accompany the firefighter for a lifetime, especially the severe burns on the face, which lead to disfigurement. Although after several skin grafts, the firefighter's face still could not be restored to its original state. The scars made the firefighter feel inferior and even reluctant to see people.

And when his daughter saw the scary scar on his face and cried in fright, it made all the audience feel distressed.

As soon as the picture turned, there were various patients who were disfigured due to skin damage and inconvenienced in the video, and finally followed the words: "I want to go surfing on the beach in a bikini", and the desire to twist The girl's face is over.

Wu Hao reappeared in front of the camera, this time he did not bring a habitual smile, but said seriously to the crowd: "These are some disfigured patients with skin damage due to various reasons. Disfigurement thus isolates them from the whole society, and they become aliens in people's eyes. Wherever they go, they receive strange attention.

It is also under these strange attention that this group of people became more and more inferior, isolated, and some even did not want to see anyone, and some directly chose extreme behavior such as suicide.

How to save this group of people, how to bring them back to health. The health here is not only the health of the skin, but also the health of the mind, which is what we have been paying attention to and researching.

And if you want these people to be mentally healthy, to make them confident and to live a normal life again, then it is necessary to change their status quo and repair their injured skin as before.

At present, regarding skin repair, the most effective and direct way to treat skin damage is skin grafting, one is autologous skin grafting and the other is allogeneic skin grafting.

The so-called autologous skin grafting is to use your own skin to repair the damaged skin. In general, it is mainly used to repair the skin that is exposed on the outside, and the skin of choice is often the skin of the less important body parts hidden under the clothes, such as the skin of the buttocks.

Because it is smooth and delicate, it is often used as the first choice for facial skin repair. Many people use the skin on their buttocks for facial skin grafts.

[In other words, the best way to read aloud and listen to books is Mimi reading, .r. to install the latest version. 】

However, there are many people who are unable to use it, especially some patients with severe body burns, who do not have a piece of skin that can be used, and naturally cannot perform autologous transplantation.

Then the only method left for them is allogeneic transplantation. There are two methods in this regard. One method is to use the skin of other donors for transplantation. However, this type of skin often has a strong rejection reaction, and the success rate is not high. And there are also some problems with this kind of allotransplantation. For example, if it is a face transplant, then the person's appearance will also change to become a donor, staring at the donor's identity and life, which will inevitably affect the transplanter and the donor. troubles the lives of the family members.

There is another kind of allogeneic skin transplantation using pig skin or tilapia skin. Although these are animal skins, they can also be transplanted. It is not to replace human skin with pig skin or fish skin, but a temporary repair process that allows the patient's exposed dermis to be protected and repaired. When the new skin grows, the transplanted pig and fish skin will automatically fall off.

Of course, this kind of animal skin graft will also produce rejection, but this is not a problem, because it is only for temporary use. The real problem is that the skin that grows in this way won't return to its original shape at all, and it will still show large scars.

Therefore, this method can only be used for burn treatment, and cannot be used for skin repair at all. "

Speaking of this, Wu Hao stopped, then looked at the camera and smiled: "Believe me, everyone knows what we are going to do.

That's right, we've been working on the research and development of medical technology, and artificial skin is also a technology area that we're focusing on.

Next, I would like to introduce our latest scientific and technological achievements in the field of medical technology, which is a special New Year's gift for you. "

After talking about this, Wu Hao paused for a while, then took a breath and continued: "As you all know, we have been working on the bionic research technology of human organs.

Under this project, there are two research directions. One is to use modern technology to create intelligent bionic artificial organs that can replace the original organs. Prosthetic limbs, we are already entering clinical trials of intelligent bionic electronic prosthetic eyes, intelligent bionic artificial hearts and so on.

The other direction is to reproduce a brand-new human organ through technologies such as biocloning or bioprinting, which can be used to replace the original damaged organ technology.

Research in these two directions has always been going hand in hand, but the former, namely electronic bionic organ technology, has achieved fruitful results. So far, many blockbuster technology products have been launched, and tens of thousands of patients have been saved and cured, allowing them to return to normal life. .

As for another biological replica organ technology, progress has been very slow. There are many reasons for this. On the one hand, of course, it is a technical problem. It is easier said than done to reproduce an identical human organ, and the technical difficulty is too great.

On the other hand, there are legal and ethical issues. A little carelessness in this regard is likely to bring huge public pressure on ourselves.

So our research is difficult and slow, but it continues.

With the continuous investment of a large number of human, material and financial resources, we have also made some achievements one after another. Today, what we want to introduce to you is the bioprinting skin technology based on our bioprinting technology, using bioprinters to print out real skin that is exactly the same as human skin, thereby replacing the original skin. Damage the skin, so that the disfigured patients with damaged skin can reappear in front of everyone with a normal appearance and return to a normal life. "
