In the operating room of the underground shopping mall research institute, Xia Cheng, female doctors, Jiang Hua, and Xia Lian are preparing to operate on a boy Duoduo who is covered with abnormal limb tissues due to genetic mutations. Pen % fun % Pavilion www.biquge.info

For more than ten days, they gave up all grievances and incomprehension, endured all kinds of humiliation in the spirit of humanitarianism and the conscience of scientific workers, turned a deaf ear to what was going on outside the window, and concentrated on gene therapy for several children with physical abnormalities.

They checked the information, did experiments, injected injections, and operated on the knife to make every effort to achieve excellence and meticulousness. They would rather get a few inflamements on their bodies, rot a few pieces of meat, or even risk their lives than let their children suffer a little mental and physical pain caused by treatment failures or mistakes.

Naturally, their efforts were not in vain. The DNA and blood tests and cell tissues of the children who received the genes gradually became normal, and the wounds that had undergone surgery healed miraculously quickly, and the scars disappeared quickly. They follow Zhenzhen's daughter Xia Nu all day long under the care of Rasha, running, jumping, talking and laughing, like a flock of happy birds.

Duoduo, who underwent surgery today, was the last and the most difficult one.

As mentioned earlier, Duoduo is the second boy born by Hua'er after Zhenzhen's daughter Xia Nu was born, but her image is far inferior to Xia Nu. Not only is he not good-looking, but he also has a lot of abnormal hypertrophic body tissue, and he is the most serious one of the children with abnormal genetic mutations.

However, his mother Hua'er is worthy of her name, there is no extra muscle maggot on her body, her melon seed face is black and red, her breasts are plump and huge, but her waist is slender and soft, her legs are long, her buttocks are not big or small, and she walks lightly and elegantly. Among the eight women who underwent human experiments, she was the most beautiful along with Zhenzhen.

But her son Duoduo is different, he looks strange and terrifying. He is not tall, only a few tens of centimeters, his body is short, but his head is huge, like a languin, two horns like bamboo shoots grow on his forehead, his eyes are large, as bright as steel bells, his thin and short body has three hands, and the shortest of them, the one like a cactus is long on his right shoulder, and the four legs, two long and two short, and the two short ones are symmetrically long on the upper part of the long legs, and the lower part of the waist, which looks like a baby's small hand. At first glance, he resembles a crab man or a twig man.

Duoduo is not like Xia Nu, he can't speak clearly, he doesn't seem to be able to speak, he can only "chatter" nonsense. When he screamed, his zigzag lips mechanically closed up and down like the mouths of a robot or puppet. The only thing that gives him an aura is his big sparkling eyes.

After several consultations, Xia Cheng and the others agreed that Duoduo was the most serious of the seven children, with the most complex surgery and the greatest risk. Therefore, put the treatment of him in the last place.

The flowers brought the flowers. The flowers are still so good-looking, with delicate facial features, delicate figures, no more and no less parts of the body, very standard. But her son is still so ugly, with pimples and branches on his body, which makes people frightened and worried, and they dare not look at it more.

?? Such a mother and son make people very puzzled. From a genetic point of view, Hua'er should not have given birth to such a child with such a physical abnormality to the extreme. At least it should be as standard flesh and blood as Zhenzhen gave birth to a summer girl!

?? Of course, it's not the flowers' fault. If it's wrong, it's the man who gave her the mutated gene. However, the man has not come forward and has not taken all the responsibility. That man was an animal, even worse than an animal!

?? Before the surgery, Hua'er has to sign an operation sheet. Although the difficulty and risks of the operation were clearly written on the list, Xia Cheng still asked the female doctor to explain to Hua'er in detail. Because the flowers are currently the only guardians of the flowers.

??” Duoduo's surgery is very complicated, the risk is very high, you have to be mentally prepared!" Although the female doctor smiled kindly, her words made Hua'er feel startled and puzzled.

?? Hua'er said: "Isn't it just to cut off the extra things on your body? The first few children are like this, I don't see any risk!"

??” Duoduo is not the same as their situation. The female doctor said.

??” What's the difference, isn't it all bone and muscle hyperplasia caused by genetic mutations? Just cut off the hyperplasia with a knife!" Hua'er said disapprovingly.

?? The female doctor smiled and patiently explained: "Although Duoduo is also a lesion caused by mutant genes, it is much more serious than the previous children in any way. For example, the number of bone and muscle hyperplasia is large, the location is important, and the surgery is difficult, so the risk is high. In addition, because the child's biological father is unknown and not at the scene, many parameters are missing, such as blood, cells, DMA comparison, etc. ”

"It's also different from theirs in terms of treatment. Xia Cheng also said, "For example, the first few children, according to the results of blood examination and the analysis of the lesion site, can replace or supplement the defective genes in the patient's body with normal function." In other words, the purpose of treatment can be achieved by transferring certain genetic material into the patient's body, making it express in the body, and replacing the diseased tissue. ”

"In terms of specific operation," Xia Cheng continued, Gene correction --- is used to correct the abnormal bases in the disease-causing genes, while the normal part is retained; gene replacement --- the normal genes are used to replace the disease-causing genes in situ through homologous recombination technology, so that the DNA in the cells is completely restored to the normal state; gene supplementation --- introduces the normal genes into somatic cells and expresses them through non-site-specific integration of genes to compensate for the function of the defective genes, or enhances the function of the original genes, but the disease-causing genes themselves are not removed; genes are inactivated --- specific antisense nucleic acids (antisense RNAs). , antisense DNA) and ribozyme are introduced into cells to block the abnormal expression of certain genes at the transcriptional and translational levels to achieve the purpose of treatment, and suicide genes, that is, a gene in some viruses or bacteria can produce an enzyme that can convert the original cytotoxic or low-toxicity drug precursors into cytotoxic substances and kill the cell itself, such genes are called "suicide genes". For the first few children, only one or two of these five methods of operation are required, and a maximum of three can be used. But for Duoduo, all five must be used, and even two more immunotherapy and drug resistance therapy must be added. ”

"What is immunity and drug resistance therapy?" said the female doctor, "It is to introduce the corresponding and antigenic determinant genes that produce antiviral or tumor immunity into the body's cells to achieve the purpose of treatment." Such as the introduction and expression of cytokine genes. In the treatment of tumors, drug-resistant gene therapy is to introduce anti-drug toxicity genes into human cells in order to improve the body's ability to tolerate chemotherapy drugs, so that the body can tolerate higher doses of chemotherapy. For example, MDR-1 in the multidrug resistance gene is introduced into bone marrow stem cells. ”

Xia Cheng said: "To say that the difficulty is high, it refers to the comprehensive use of the first five methods. Because, as far as I know, there has not been a single case in which a combination of five methods has been used to treat a genetic mutation. To say that the risk is high refers to the last two. Because immunogene therapy and drug-resistant gene therapy are mainly extraordinary measures for cancer patients. If the young Duoduo comes to these two treatments after the first few treatments, I am afraid it will ......"

"I'm afraid of what?" Flower asked in horror.

"I am afraid that due to chemotherapy, the main organs will be severely damaged and I will die of failure. The female doctor said bluntly.

"So we say, as a mother, you should be fully mentally prepared!" Xia Cheng said.

"Sign it!" the female doctor urged.

The flower bowed her head and was silent for a long time. She suddenly looked up, but didn't say anything, only a pitiful and hesitant gaze on her son's face. Then she looked up and asked Xia Chengdao, "What if you don't have surgery?"

"The abnormal tissues and limbs in his body will also grow and become more human-like, and animals will not be like moking, which is still good. ”

"What about the bad ones?" asked Flower.

"Live for two months at most. Xia Cheng said sadly.

Duoduo seemed to understand Xia Cheng's words, her little hands slapped on the flowers, and her mouth was "chirping" and begging, as if to say: "Mom, I want surgery, I want surgery!"

"What if it happens?" asked Hua'er again.

Xia Cheng said: "Although surgery and treatment are difficult and risky. But after surgery and treatment, Duoduo will return to normal genes like the previous children, and the excess limbs and tissues on her body will be removed, and she will not grow any longer. That is, he is the same as a normal person. Of course, the wind grows quickly, and the premature speech and maturity are the same as the previous children, but it is by no means a disease, but a normal and healthy person. ”

After hearing this, Hua'er suddenly stood up, took Duoduo's long hand, and knelt in front of Xia Cheng and the female doctor.
