Phenylketonuria? This kind of disease is rare.

Chen Hao looked through the medical record card made by the hospital, handed the medical record card back to Ms. Hu, and said, "The hospital's diagnosis and treatment report is not wrong, your child does have phenylketonuria." ”

Phenylketonuria is caused by enzyme defects in the metabolic pathway of phenylalanine, and is named because children excrete a large amount of metabolites such as phenylpyruvate in their urine, and is an autosomal recessive inheritance.

When both parents are carriers of the gene, there is a 25% chance that they will pass on the gene to their children and cause them to develop phenylketonuria from birth.

This Ms. Hu's luck is really not ordinarily bad, a quarter of the probability is that they have caught up, and both children have inherited phenylketonuria.

Phenylalanine is an essential amino acid that the body cannot produce on its own and depends on food.

If there is no phenylalanine, protein cannot be synthesized in the human body, and if there is no protein, it will be malnourished, and in severe cases, people will not be able to survive.

However, if phenylketonuria patients consume high-protein foods, phenylalanine cannot be metabolized normally, and excessive phenylalanine accumulates in the body, which will damage the child's intelligence.

Therefore, the amount of phenylalanine in the food eaten by the child should not be sufficient to maintain the child's growth and development, but not excessive. Otherwise, it will cause harm. Therefore, children with phenylketonuria must follow a low-phenylalanine diet, and the few grams of food needed at each meal must be weighed before meals.

Chen Hao pointed at the boy and said to Ms. Hu: "This is your son?" ”

"Yes, because after he was born, our parents did not know that he had this disease, and as a result, he was fed ordinary food, and then his hair gradually turned yellow, his skin turned white, and after three months he developed intellectual and speech development disorders. Due to the late detection and lack of money for treatment, Xiaoke's current intelligence is similar to that of a four-year-old child. Xiaoke, call your uncle well. ”

"Hello uncle." Xiao Ke smiled innocently, and the words he spat out were indistinct.

Chen Hao responded with a smile: "That's good." You should have found out about your daughter's condition as soon as she was born, right? ”

"Yes," Ms. Hu replied, "because of the lessons of Xiaoke, we did a newborn screening for the child as soon as she was born." Once it was determined that she also had phenylketonuria, we started feeding her special food. ”

"But even if you buy the cheapest special food in China, you will spend 2,000 to 3,000 yuan a month on the special food for your child. Because of the poor family economy, even if there are donations from well-wishers, we can only ensure the supply of special food for our daughter Xiaojuan, while my brother Xiaoke can only eat ordinary food, and as a result, Xiaoke's intelligence becomes worse and worse. Dr. Chan, is there any hope for the illness of the two children? ”

"Mom, I want to have a birthday cake, I want to eat ice cream." At this time, Xiaojuan raised her head and pleaded with her mother.

"Xiaojuan, when the doctor uncle takes care of your illness, my mother will buy it for you immediately." Ms. Hu recalled that she had eaten a popsicle last summer, only to find that her daughter had secretly picked up the wrapping paper of the popsicle from the garbage bag, and she couldn't help but feel sad.

Chen Hao looked at Ms. Hu and her two children and said, "Phenylketonuria is a genetic disease, which can only be controlled according to current medical conditions, and cannot be completely cured. Your son has impaired his intellect and is generally irreversible. You say that I will be able to cure these two children, but I can't jump to conclusions, I can only say do my best. ”

Chen Hao's words were a bit conservative, and Chen Hao knew that Qian Qian had the ability to cure this genetic disease caused by genetic defects. Because Qianqian had altered the genes in Zhao Jianjie's body, causing him to suffer from systemic lupus erythematosus, a genetic disease. The current Xiaolong also has this ability, but Chen Hao is reluctant to talk too much, otherwise it will give people a feeling of bragging.

"Is that a cure likely?" From Chen Hao's tone, Ms. Hu heard a different feeling, and Chen Hao did not refuse directly.

"Fifty percent." Chen Hao casually reported a number.

This figure was much beyond Ms. Hu's expectations, and the words she had heard the most in the past were "impossible" and "hopeless".

"Then please Dr. Chen, please save my child." Ms. Hu didn't care about whether Chen Hao was a liar or not, for the sake of her children, let alone a liar, even if it was a fire pit, Ms. Hu would jump off without hesitation.

"Okay, your daughter will come first today, and your son will be seriously ill, so let's wait until tomorrow."

After obtaining Ms. Hu's consent, Chen Hao left her daughter Xiaojuan alone, and after letting Xiaojuan sleep, Chen Hao pierced the silver needle into Xiaojuan's neck and began to urge the true qi to lose to Xiaolong.

Because the genes in the genetic material of the cells are defective, Chen Hao needs to use nanorobots to repair the genes of each cell. If you compare a patient to a building, then cells are every brick. Can you imagine how long it would take to fill all the holes in every brick in a building?

Therefore, the treatment of genetic diseases is a very huge project, fortunately, this work of repairing genes does not need to be done by Chen Hao himself, otherwise he would have to go crazy.

With the support of Chen Hao's huge energy, Xiaolong commanded the nanobots to repair genes efficiently and accurately.

An hour passed, and Chen Hao saw that most of his energy had been consumed, but the work of repairing genes was only halfway through, and if this continued, his energy was exhausted, and he could not complete the repair of genes.

Chen Hao didn't want to give up halfway. What to do? Can you try to absorb the energy from the outside world while exporting it to the little dragon?

Try it again. After Chen Hao transported the true qi to the brain domain, he separated a thin wisp of U-turn and returned to the Qi Sea Acupoint after completing the half-circle of energy circulation, and Chen Hao found that there was really energy entering his body.

It may be that there is no control of the mind and full attention, or it may be the weakness of the circulating energy, and the energy that enters the body every time is pitiful, not even one-tenth of what it is on a normal day.

However, although the mosquito legs are small, they are also meat, it is better than nothing, Chen Hao secretly comforted himself in his heart.

In this way, Chen Hao lost his true qi to Xiaolong, and at the same time carried out energy circulation to replenish the lost true qi and energy, so that although the speed of repairing genes slowed down, he could persist for a longer time.

Even so, Chen Hao almost couldn't hold on, and in the last ten minutes, almost every minute Chen Hao could faint anytime and anywhere. By the time all the girl's genetic repair was completed, the energy in Chen Hao's body would be exhausted.

Looking at Chen Hao at this time, his face was pale and sweaty, his hands and feet were weak, panting like a cow, and he almost collapsed to the ground.

Chen Hao sat on the edge of the bed panting, and kept thanking: thank you for the summoning system, thank you Xiaolong, thank you for the breakthrough this morning, thank you for the petite Xiaojuan, thank you AATV, thank you BBTV, thank you CCTV......
