"Ah, Aunt Mei, you came just in time, we are talking about ......"

"We're saying, how does this genetic treatment work?" Xia Cheng didn't wait for Lasha to finish speaking, so he took her words and said to Mei Xiang, "You are very good at this, come up with ideas! Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ”

"Really?" Mei Xiang said, "I seem to have heard you say about the river, Jiangxi Yulin." Hey, who is Jiangxi Yulin?"

Jiang Hua was young and reacted quickly, knowing that Mei Xiang listened to the speech inside outside, and she made a mistake if she didn't tell the truth. So he said, "Professor Xia asked us to study gene therapy for those children. But in the research, everyone was puzzled as to why Bulp suddenly wanted to kill Professor Xia, so they asked Professor Xia what was going on? Professor Xia said that it was because Professor Xia asked Bulge Tower to tell him who Jiangxi Yulin was, but Bulp refused to answer, so Professor Xia bit Bulge's ear in anger, which made Bulp Tower kill. ”

Rasa said excitedly: "Jiangxi Yulin is a traitor to the earth, he betrayed Professor Xia's scientific research achievements and the round-trip time and path of Professor Xia and his party to participate in the Harmony Star Scientific Expedition to the tower, and accurately told the tower. Therefore, our 203 spaceship was hijacked by the Araceans, and we were kidnapped by the Bulge. ”

"Teacher Mei, it is said that you and Professor Xia are classmates in college, who do you say knows the exact time of his interstellar trip?" Carter asked.

Mei Xiang said: "It's true that Lao Xia and I are classmates in college, and we used to ...... He specializes in the study of genes for the rapid development of life, and I know it. But I didn't hear him say anything about his interstellar trip, and I didn't hear anyone say it. Hey, probably because we haven't been in touch for a decade or two!"

Rasha was straightforward and said, "Aunt Mei, I heard Professor Xia say that this person nicknamed Jiangxi Yulin has been following Professor Xia to study the genes of the rapid development of life for more than 20 years, and he is both a friend of Bulp Tower and a friend of Professor Xia, and he is now by Professor Xia's side. Aunt Mei, it can't be you, right?"

Mei Xiang smiled stunned and said, "Miss Rasha is in the Arabian Nights, right? I just said that it is true that Lao Xia and I are classmates in college, and we have been in love. I also know that my old classmates are dedicated to the study of genes for the rapid development of life. But I didn't know about his interstellar trip at all, I didn't hear him say it, and I didn't hear anyone say it. I also have my own research project, and I have no interest in everything about him, let alone time to inquire about it. Besides, if it were me, would I let my daughter Yang Li go all the way? She, but my sweetheart! My student Xia Lian also knows this. ”

"I believe what Teacher Mei said. She can't be Jiangxi Yulin. Xia Lian said.

"Forget it!" Xia Cheng said, "Let's get back to business, let's study the gene therapy for those children!"

"Professor Xia," Rasha asked, "do you really agree to give Bulge a gene therapy to a few monsters?

"No!" Xia Cheng said categorically, "I agreed to give gene therapy to several children, not out of persecution or aiding in abuse, but out of the conscience and love of a life scientist, who is responsible for the normal survival and existence of human beings." You know, though they look strange, they are also human beings. Some of them may not be able to save their lives if they do not receive gene therapy in time. We are scientists who study the healthy development of life, and we cannot afford to save them without saving them, and watch them die. ”

Besides, Xia Cheng regained his senses under the inspiration of Branini and his daughter Xia Lian, and saw the hope that the interstellar police would come to the rescue. Gene therapy may be a good opportunity and a countermeasure, so why not kill two birds with one stone?

"Rasha, you go and replace the female doctor and let her study with us as well. By the way, the refusal jackals also called together. Summer said to Rasha.

"You can't stop barking, he's a bulge!" said Carter.

"Out of the way. Xia Cheng said, "I have observed this kid very well, since his brother K Tiger and K Leopard were killed by Bulge, he seems to have changed as a person, and he is not hostile to us." Go, and call him with you. ”

"OK!" Rasa replied and wanted to go out.

"Slow!" Xia Cheng stopped Rasa again and said to everyone, "Let's all go to the conference room! Tell the female doctor, call the two Aracean doctors, and let's go to the conference room to study together. ”

"Okay!" Rasha replied.

"Teacher, are you okay, this body?" Jiang Hua asked.

"Okay!" Xia Cheng got out of bed with the support of his daughter Xia Lian, and said while getting dressed, "To be honest, after I came to Tiannanxing, I really didn't do anything practical except to treat the husband of the woman in the underground street and save his life. But unfortunately, her husband was later beaten to death by Bulta's bodyguards. This time, I really want to do something useful to humanity. If our earthly gene therapy method is also effective for aliens, I think it will be the best thing in the universe. As far as I know, the aliens on many planets are overwhelmed by how useless and horrible and ugly things grow on their bodies are overwhelmed by what they want to do about it!"

A few minutes later, everyone came to the conference room and sat down.

Xia Cheng said: "Today we are going to study the problem of gene therapy for several children. Except for Captain Carter and Jackal, the others are life science workers from Earth and Aracea. In particular, the female doctor and Ms. Mei Xiang are experts in this area. I don't know about the female doctor, but I do know that Ms. Mei Xiang has a deep research experience in gene therapy. Moreover, her husband, Vice Mayor Yang Yinqing, is also a supporter of my scientific research project from beginning to end, and he was also born in this field. Well, let's give the floor to Ms. May first. Everyone is welcome!"

After a round of applause, Mei Xiang said: "Professor Xia has won the award! Who in the world does not know that Xia Cheng, a well-known earth life scientist, has devoted his whole life to researching the genes of rapid development of life, breaking Darwin's theory of biological heredity and survival, which has dominated the biological world for nearly 1,000 years. The creation and practice of life is not only the only way to survive the fittest, but also to enrich, improve and create new life forms by relying on high-end scientific means of human beings. As for gene therapy, although I didn't study medicine directly in college, and I also engaged in teaching after graduation, I have never engaged in gene therapy, but I am not very unfamiliar. Because life and genes are closely linked, we also know a little about gene therapy. ”

"Teacher Mei, then tell us about it, it's okay to have a long insight!" Carter said.

"But no matter what I say, in front of Lao Xia, Professor Xia and this female doctor, they are all class axes. Mei Xiang said.

Xia Cheng said: "It doesn't matter, in a sense, everyone sitting here is a family. The family doesn't talk to each other, female doctor, you say yes?"

"That's right!" said the female doctor, "Teacher Mei, you can rest assured that you can just say it, and we will listen to you." ”

Mei Xiang said, "Okay, since everyone wants to hear it, I'll talk about it! ”

Mei Xiang coughed twice, cleared her throat, smiled, and said, "Gene therapy is mainly gene therapy (geherapy) for genetic diseases in medicine. It refers to the application of genetic engineering technology to introduce normal genes into the cells of patients to correct the defects of disease-causing genes and cure genetic diseases. The correction pathway can either repair the defective gene in situ or transfer a functional, normal gene into a part of the cell's genome to replace the defective gene to function. As she spoke, she turned around and asked the female doctor, "On Earth, we understand it like this, but in Aracea, I don't know if we understand it this way, right?"

The female doctor said, "Teacher Mei is right. Gene therapy is one of the high-tech biomedical techniques that introduce human normal genes or genes with therapeutic effects into human target cells in a certain way to correct gene defects or exert therapeutic effects, so as to achieve the purpose of treating diseases.

"So what are the methods of gene therapy?" Mei Xiang said, "At present, the methods of gene transfer on Earth are divided into biological methods, physical methods and chemical methods. Adenovirus vectors are one of the most commonly used viral vectors for gene therapy. Of course, with the development of science, there will be many and more advanced methods. You say yes, female doctor?"

"Yes. "A gene is the basic functional unit that carries the genetic information of an organism, and it is a specific sequence located on a chromosome. The introduction of exogenous genes into biological cells must be carried out with the help of certain technical methods or vectors. At Aracea, gene therapy is currently mainly used to treat diseases that pose a serious threat to human health, such as hemophilia, cystic fibrosis, familial hypercholesterolemia and other genetic diseases, as well as malignant tumors, cardiovascular diseases, infectious diseases, etc. However, the treatment is different from the conventional approach. “

"Not bad!" Mei Xiang said, "gene therapy is different from conventional treatments. In general, the treatment of diseases targets various symptoms caused by genetic abnormalities, while gene therapy targets the root cause of the disease --- the abnormal genes themselves. I don't know what methods are currently being used for Aranan Star. “

The female doctor said: "At Aracea, there are currently two forms of gene therapy: one is somatic gene therapy, and the other is germ cell gene therapy. The former is being widely used, while the latter is limited by its ability to cause genetic alterations. “

"As far as I know, the specific forms of gene therapy commonly used on Earth are: 1 Gene correction, that is, correcting the abnormal bases in the disease-causing genes, while the normal part is retained. 2. Gene replacement, that is, the use of normal genes through homologous recombination technology, in situ replacement of pathogenic genes, so that the DNA in the cell completely returns to the normal state. 3. Gene addition, that is, the normal gene is introduced into somatic cells and expressed through non-site-specific integration of genes to compensate for the function of defective genes or enhance the function of original genes, but this form of pathogenic genes themselves has not been removed. 4. Gene inactivation, that is, specific antisense nucleic acids (antisense RNA, antisense DNA) and ribozyme are introduced into cells to block the abnormal expression of certain genes at the transcription and translation levels, so as to achieve the purpose of treatment. 5 Suicide genes, a gene in some viruses or bacteria can produce an enzyme that converts the original non-cytotoxic or low-toxicity drug precursors into cytotoxic substances and kills the cells themselves. “

"Crackling ....."

The wonderful presentation of gene therapy from theory to practice by female scientists from the two planets ushered in enthusiastic support from the audience.

The female doctor said, "Don't welcome you yet, as for whether what we said is right or not, Professor Xia hasn't said anything yet!"

Mei Xiang also said: "Yes, let's listen to Lao Xia, Professor Xia's opinions!"

Xia Cheng smiled and said: "The two female scientists on the two planets have interpreted gene therapy so perfectly, do I have anything else to say? If I really want to say it, I will say, how to start working according to the actual situation of the individuals we want gene therapy, that is, several children!"
