Suddenly, Yu Dong turned around abruptly and said in a deep voice: "Do you know how much impact genetic modification will have on human beings? Whether it's good or bad? I'll give you a ready-made example, just your eyes. ”

"My eyes?"

"yes, I'll give you an analogy, don't mind." Yu Dong said with a smile.

"If there is no cure for your eye disease, blindness is the reality you are about to face, but your 'genetic research' is the only treatment that can give you back your sight, will you accept it?"

"That's nature." Zhang Tianlin replied without thinking.

"Don't rush to answer." Yu Dong continued, "Since 'gene therapy' has just come out, it is still unstable in many aspects. Its side effects are so great that it may even take your life, will you still accept it? ”

Zhang Tianlin just thought that Yu Dong was only talking about it out of concern for his old friends, but now it seems that he does not agree with his own point of view.

Sometimes, Zhang Tianlin thinks that as an expert in a certain field, in order to achieve scientific progress and benefit mankind, he will do his best, and even sacrifice his own life.

However, there will always be people who have to stand up, who speak out against it, who criticize it, and you need to make your point of view to them, try to convince them, and more than once.

It's ridiculous to think about!

If those people don't understand, why ask for their consent?

In the final analysis, it is the hearts of the people who are at work.

The human heart can be expressed in terms of morality and human rights, and can also be interpreted in terms of kindness and malice.

The human heart is flawed, and the most intuitive is desire.

It's not just lust, when a person's desire for money, power, status, and fame exceeds a certain limit, the human heart may be distorted. In this way, it leads to the terrible fact that you will do whatever it takes to get what you want.

At that time, he will be so blessed that he will not allow others to think of him.

In addition, he will try his best to suppress anyone or anything that threatens him, and he will use any means to fight back until he is eliminated.

Zhang Tianlin's mind was churning, and he didn't know why he thought of these things.

"The meaning of the existence of anything is that it exists, and existence must have meaning." Zhang Tianlin said unhurriedly, "'genetic modification' will definitely benefit mankind, but it will also bring bad effects, this is the two sides of things, and everything is inevitable." ”

"I admit it, but I just want to advise you to think carefully about the negative effects of genetic modification, and whether you can afford it." Yu Dong's tone softened, "Or can human beings afford it." ”

"Old Yu, don't worry," Zhang Tianlin said sincerely, "I assure you that I will not easily apply it to humans until I get real experimental data." I know how much of an impact it has on humans......"

Yu Dong smiled, originally just reminded him, but he didn't expect to say so much.

So he said, "Your research topic is too advanced, and I am purely curious. It's just out of the concern of an old friend, don't think about it. ”

"No, no." Zhang Tianlin smiled and said, "What kind of person are you, to be honest, I know better than you, hahaha." ”

After saying this, Zhang Tianlin signaled that he was really leaving.

"If you feel uncomfortable, call me immediately!" Yu Dong asked again.

After Zhang Tianlin's figure disappeared at the end of the corridor, Yu Dong's face changed.

He sighed, slumped in his chair, pondered for a moment, and still had a sad face.

He couldn't cure his old friend's eye disease because it was discovered too late, the lesion had already occurred, and it was in an advanced malignant stage.

The ensuing symptoms are obvious, starting with blindness in the right eye, then blindness in the left eye, and then spreading to the heart and lungs......

This cycle is very fast, less than half a year, maybe shorter.

"Only by completely removing both eyes and all the tissues around the eyes may be able to save his life, but for him, it is better to die."

Yu Dong muttered to himself, he really couldn't think of any medical methods.

"What needs to be done is still to be done, maybe there will be a miracle."

"Xiao Zhang, there are two things that you need to deal with. The first thing I did was to contact the United Government Medical College, and I said that my schedule had changed at the last minute, and that I would cancel my lecture tomorrow morning. ”

"But Dean, the medical school has made enough preparations, just waiting for you to ......"

Yu Dong didn't wait for him to finish, and said calmly: "They will understand, and I believe that you will also do this well." ”

"Okay." Xiao Zhang said reluctantly.

"The second thing is to inform the doctors in the department above the rank of associate professor to gather in the conference room at half past eight tomorrow morning, and say that an important academic discussion will be held."

"Remember, all doctors above the rank of associate professor are required to participate!" Zhang Tianlin emphasized.

As Professor Yu's assistant, Xiao Zhang had never encountered such a thing, and his intuition told him that something important had to happen.

He didn't dare to ask more, so he immediately went to do it.

After a patient explanation, the first thing was finally done, although the medical school showed dissatisfaction, but in view of Yu Dong's reputation, he didn't say much.

After Zhang Tianlin left the Central Hospital, he did not return to the Aerospace Institute, but went straight to the Institute of Biology. After going upstairs, he went straight to the Genomics Research Section, where his colleagues greeted him.

Zhang Tianlin walked into the locker room to change clothes, and then entered the laboratory.

After a long delay in the hospital, he couldn't wait to see the results of the experiment!

"Xu Shan, how is it, is the data out?"

As soon as he entered the laboratory, Zhang Tianlin couldn't help but ask.

A middle-aged man in a white lab coat appeared in front of him, although the lab coat was a little wide, but it still couldn't hide his strong body.

Xu Shan neither looked back nor turned around, but replied motionlessly: "Mentor, you are here." A set of data has been released, but it is not ideal, and I am conducting a second experiment......"

It turned out that he was injecting some kind of liquid into the three mice, so he didn't turn around.

Zhang Tianlin slowly approached, and only after Xu Shan's operation was completed did he ask, "The data is not ideal?" What happened? ”

"It's quite different from the expected result...... Xu Shan said with a bit of frustration.

"Be specific."

"According to the expected setting, the fusion degree should reach 80% and the devouring level should reach 50%. However, the actual data shows that the fusion degree is 40%, and the phagocytosis is as high as 70%, which is too far from the set value. ”

"Well, the deviation is indeed quite large," Zhang Tianlin thought thoughtfully, "What happened to the three guinea pigs?" ”

"All dead!" Xu Shan swallowed a mouthful of saliva as he spoke, "The whole process lasted less than half an hour, and the three mice died one after another. And when he died, his whole body convulsed intermittently, and it seemed to be painful. ”

"Alas, less than half an hour ......"

Zhang Tianlin looked at Xu Shan's regretful appearance, reached out and patted him on the shoulder, and said with a smile: "Don't be discouraged, doing research is like this, you need to experiment over and over again." Moreover, every factor in the process of the experiment can have a big impact on the experiment, even the most subtle changes. It's not the first day you've experimented, and you might succeed next time. ”

"However, my mentor, if you theoretically extrapolate that even if the gene fusion is only half of the set value, the main gene will still accept some foreign genes. Moreover, the process is also very slow, according to the theoretical value, it is about an hour and a half! ”

Xu Shan was puzzled, trying to think about every detail of the whole process, trying to find out the loopholes.
