Time passed little by little, and no one in the operating room dared to relax for half a minute. And Zhang Yan is still in a coma under the anesthetic effect.

Zhang Yan's adoptive father and adoptive mother clasped their hands together, feeling uneasy in their hearts.

The hours of surgery were short and long, and none of the people waiting during this time even drank water or went to the bathroom.

"Abba, the operation is complete!" The small red voice sounded in Lu Zixin's ears, and suddenly, all the people waiting stood up and looked at Lu Zixin.

Lu Zixin nodded and said, "Don't worry, everyone, the doctor should come to inform you soon." ”

After a short time, the surgeon looked tired and came to inform him of the situation, and he said: "The transplant is basically successful, but the follow-up reaction is still being observed." For the next month, the patient will be kept in a sterile chamber for observation. ”

Hearing his words, everyone barely breathed a sigh of relief. Just because the transplant is successful does not mean that the treatment has been successful. It also depends on whether the patient will have rejection, and whether the 3D printed bone marrow really works.

"Thank you, doctor, thank you!" Zhang Yan's adoptive parents stepped forward to thank him.

Lu Zixin knows that transplant surgery is not the end of treatment, but the beginning!

In the following time, Zhang Yan's condition was closely watched by the treatment team.

Because she had just undergone surgery, the new bone marrow and white blood cells in her body had not yet grown, so she lost her immunity to bacteria and had to stay in a sterile warehouse. Even if you eat and drink, you must disinfect it with a high protein input.

The first few days were the healing period of the operation, and Zhang Yan's body did not have major adverse reactions and was still under control.

A week later, after observation, Zhang Yan's white blood cells began to grow, which proved that her immune system was beginning to rebuild.

According to this situation, after twenty days, she will be able to transfer to the general ward. The attending physician analyzed that during this time, Lu Zixin often took time to observe Zhang Yan's condition.

In other parts of the city of the future, construction is taking place, and majestic buildings are being built, especially the landmark science and technology tower in the center of the city, which has laid the foundation, penetrates deep into the underground rock formations, and uses polymer polymeric metal materials and scientific structural design to resist large-scale natural disasters.

A full month has passed since Zhang Yan's bone marrow transplant, and Zhang Yan has officially been transferred from the sterile warehouse to the general ward to continue observation.

If her condition improves, it means that the treatment is basically successful, and the treatment will be successful.

"Yanyan, look, I painted a picture for you. In the ward, Hong Xiaoxiao showed Zhang Yan her paintings, which were portraits of Zhang Yan, which looked a little abstract.

This is not a computer-based synthesis by Hongxiao, but a painting that simulates human neural networks and physiological responses, which is of great significance.

Of course, the little girl Zhang Yan didn't know this, she smiled and said, "Is this me?

Hong Xiaoxiao showed an innocent smile like a child, and in the projection, there seemed to be more agility.

Outside the ward, Zhang Yan's adoptive mother saw this scene, her eyes gradually softened, and she hoped that this scene could continue to be staged.

This time, reality did not disappoint her. Zhang Yan was observed in the general ward for two months, not only did there be no rejection, but also recovered quickly, and the white blood cells in her body have returned to normal, which means that her illness is basically cured!

"This is another miracle in medicine! Bioprinted organs can replace donated organs, and there is no rejection reaction, how many patients will benefit from this!" Every staff member in the hospital is sincerely happy.

Zhang Yan can already be discharged from the hospital, and after being discharged from the hospital, she still needs to pay attention to her diet and life. Go to the hospital regularly for check-ups, and if there is any abnormal reaction, you should give us feedback in time. When the doctor informed Zhang Yan's adoptive parents, both of them wept with emotion.

How many days and nights, worrying, sleepless nights. I thought it would end in a tragedy, but I didn't expect that under the power of science and technology, Zhang Yan was reborn, how not to move and excite them.

On Zhang Yan's birthday before she was discharged from the hospital, the medical staff also held a birthday for the little girl.

The ward was projected by Hong Xiaoxiao, turning into a brilliant sea of sunflowers, in the sea of flowers, the little girl wore a garland, laughing innocently, this scene was recorded by the instrument, becoming a precious scene in the history of medicine!

The next day, the scene went viral in the news media.

Today's Express: "The first case of 3D bioprinted organ transplantation was successful, and the patient has been cured!"

People's News: "Hongxin International Hospital has created another brilliant achievement, artificial organs can be transplanted!"

Headline: "The world's first 3D bioprinted bone marrow transplant was successful, and bioprinting will solve another problem in the medical community?"

Even the scientists of the National Biomedical Center congratulated and expressed their happiness and blessings for the medical innovation of Hongxin International Hospital.

Of course, there are also references to the ethical aspects of science in this technology. Hongxin International Hospital immediately stated that it would conduct experiments or treatments under the supervision of a biomedical ethics committee, and that the technology would be used in medical treatment.

After the successful 3D bioprinting bone marrow transplantation, Hongxin International Hospital has successively tried 3D printing blood and kidney, all of which have been successfully treated, which has further increased the patients' confidence in 3D bioprinting technology.

Hongxin Group said that it will establish the world's largest "3D Bioprinting Technology Co., Ltd." in the city of the future, which will provide medical institutions around the world with materials needed for blood and organ transplantation, and alleviate the problem of shortage of blood banks and organ banks.

From now on, the number of patients who die due to lack of blood or lack of matching transplanted organs or rejection of transplanted organs will be greatly reduced.

Because of this news, the city of the future has become popular again, and the capital groups that have come here to invest and build are lining up to grab their heads.

And the general public is also looking for ways to move to the city of the future. Now everyone can see that this city is destined to become great!

Just when everyone was still attracted by 3D bioprinting technology and the city of the future, a piece of news suddenly broke out and took everyone's attention.

At a world-class robotics show in the United States, Boston Robotics showcased their latest "intelligent power robot".

In the field of robotics, Boston Robotics has always been at the forefront of the world. And this time, the intelligent robots they showed were more agile and intelligent than before. In some respects, they have completely surpassed humans.

Boston Robotics announced that it has received a large number of orders from the civilian and military sectors and will continue to invest in building smarter, more powerful robots.
