Just after Yun Heng submitted relevant information to the relevant departments for the application for clinical trials, he did not encounter much resistance and the project passed the approval.

Yun Heng's experimental data are very detailed and the effect of the drug is very clear. Although it is still dangerous, the benefits are also very considerable. Drugs that can directly cure AIDS are so tempting.

At present, the index of AIDS patients in China is soaring year by year, especially the college student group. The proportion of AIDS patients is increasing year by year, and the Health Bureau has always been very worried.

Even though the drug developed by Yun Heng is a genetic drug, at least there is a precedent for this genetic change.

There is about 10% of the R5 gene in Europe that is born with 32 carbon groups, and it lives well, and it has no harm to the body. Instead, it brings the benefits of immune Hiv virus.

In addition, Yun Heng's experimental results clearly show that this drug only acts on hematopoietic stem cells and r5 genes, and there is no other genetic changes. All the hematopoietic ability of hematopoietic stem cells is normal.

The r5 gene has become a gene that can be immune to the Hiv virus. This is a good thing, and it is naturally impossible not to pass the approval of clinical trials.

This made Chen Changan very depressed. His Down syndrome treatment project also conducted some biological experiments, which effectively suppressed the extra chromosome 21 in the monkey gene. However, due to the unclear effect of the final result, it was too risky to change all genes.

Although men with Down's children basically lose their fertility function, there are also three or four cases of male Down's syndrome having a next generation.

Women with Down syndrome have half the chance of getting pregnant.

Once their next generation carries an extra xist gene, what will happen? When the fertilized egg develops into an embryo, who knows whether this xist gene will randomly capture a chromosome to form a Papist subsection? Once this happens, the baby will not only have one more chromosome 21, but also one less other chromosome. The consequences are terrifying.

No wonder the Drug Administration has not approved clinical trials...

While considering whether to go to small African poor countries such as Ethiopia or the Gambia to conduct clinical trials, Chen Changan is also considering whether his plan is incorrect.

When it comes to genetic changes in the entire human race, the risk coefficient is too great and the public pressure is also very high, even though he successfully developed this gene inhibitor.

However, all cells in Down's body have an extra xist gene implanted, which obviously will not be accepted by the public and scientific scholars.

Once these Down children who have received gene therapy combine with ordinary people and give birth to the next generation and inherit this DNA with one more xist gene, no one can tell what will happen, including Chen Changan.

Chen Changan hesitated.

This time, the treatment plan for Tang's children is the first project he led from project establishment to research and development. In addition to some key technologies, he extracted from the advanced knowledge in his mind, and the specific treatment plan was thought out by himself.

For example, Ruikang's previous R&D projects were like building a house, the treatment plan was design drawings, and the technology was bricks, tile and steel bars.

In the past, Yun Heng and Wang Jia decided on the appearance and design drawings of the house, and then Chen Changan provided some corresponding technical tools as aid.

For this Down syndrome project, Chen Changan needs to design a high-rise building himself, that is, a treatment plan, and then conduct specific research and development.

The problem is that he is not sure whether his treatment plan is correct or not, and whether it will eventually build a dangerous building, which is extremely harmful.

This made him once have the idea of ​​putting aside the hasty idea of ​​running to Africa for clinical trials.

Once this clinical trial is done, the recruited volunteers are implanted with a xist gene and it will be difficult to change it. There is no regret medicine.

If these people's Down syndrome is really cured and even regenerate their ability to reproduce, if this artificially modified gene is spread and integrated into the human gene pool and some unpredictable genetic disasters occur, Chen Changan may become a human sinner.

Chen Changan needs some time to revise his treatment plan, and may even overturn it all.

This is how scientific research is. Even most medical projects in the world, like Chen Changan, are stranded or even stagnated for several years.

Like the previous projects of Ruikang, it was successfully developed in one or two years, and it was abnormal that there was basically no wrong path or the plan was wrong.

Now Chen Changan himself has started a project with his advanced knowledge without ready-made treatment plans, and finally encountered bottlenecks and difficulties.

After much consideration, he decided to temporarily put aside the research topics related to Down syndrome.

It may take another year and a half to re-plan the R&D plan and treatment direction.

However, although the Down syndrome project was temporarily shelved, Ruikang Group did not stop there, and the Anime R&D Base and Ruikang Electronics immediately launched a new project.

【Private Medical Robot】

Or a private family housekeeper is not wrong.

After Li Yuntong took over the task, she took her huge mechanical engineering team to carry out related bionic robot development work.

Chen Changan set a tone for them, that is, the simulation of this robot should not be too high.

It is just not to behave like a real person, do not use bionic skin, and it is best not to create facial features like humans on the face. It is best to make cute humanoid robots like Dabai instead of bionic people.

For ordinary people, buying a bionic robot that is almost the same as humans and going home will be a psychological burden.

Bionics look like they are real people. On the one hand, they will have a uncanny valley effect, and on the other hand, they will put a robot at home that looks like a real person. Even if it absolutely follows any instructions from you, it will always feel strange and requires a lot of courage to adapt to this matter.

Moreover, if some single young people buy a bionic man of the opposite sex, if they do it realistically enough, and the positioning of this robot is service-oriented, there is a high probability that these young people will place some emotions that should not appear on the bionic man.

At that time, all kinds of big things will happen, and even challenges the social outlook and human ethics system...

Therefore, it is best to make a private medical robot image and make people see at a glance that this is a robot.

And considering the characteristics of its home use, it is best to be cute and cute. Robots like Dabai are indeed the most suitable image for home use. I have to say that those who engage in science fiction movies are indeed very visionary.

Chen Changan planned to copy their design ideas.

No, can cultural people be called copying? This is called reference!
