Chapter 212 Interested in my genes?
Zhang Shan really didn't expect to sleep for so long,

Such a small situation, so exciting!
Moreover, the experts at this time did not find it troublesome to see Zhang Shan who had awakened.

That look is like the first time humans discovered a giant panda~
It’s not surprising if Zhang Shan can’t sleep!
But at this time he woke up, but things were completely different!

Zhang Shan can understand the mood of the doctors, this case is equivalent to the first dormancy of human beings~
Speaking of sleep mode, it generally describes the machine!
Hibernate mode is when the computer will save an image of the desktop and all open files and documents when it is not in use, and then can be directly disconnected from the power source.On subsequent power-ups, files and documents are restored to open on the desktop as they were originally used.

But in fact, many animals also hibernate!

In order to adapt to changes in the environment, some animals have almost stopped their life activities.

In nature, land animals such as snakes, bats, frogs, hedgehogs, bears, etc. have the habit of hibernating.

Dormancy is a unique physiological process for animals to adapt to the environment and maintain individual survival.

The environmental conditions in nature are ever-changing, and sometimes this change is more severe, and may cause the lack of food or water.

In this case, some animals have a physiological phenomenon of weakened activity, no food, lazy movement, decreased reflex activity, and a lethargic state. This is the dormancy of animals.Animals in a dormant state slow down their breathing and heart rate, body temperature, and basal metabolic rate. In short, all life activities are reduced to a minimum, and they only rely on the substances stored in the body to maintain life.

Both ectotherms and warm-blooded animals have dormancy, but the mechanisms of the two are quite different.

Because the former does not have the ability to regulate body temperature, its body temperature can only change with the change of environmental temperature. Therefore, when the environmental conditions (especially the temperature) are not suitable for its physiological activities, the animals will passively enter a state of paralysis and enter dormancy, and the environmental conditions will return to normal. Never sleep before.

The dormancy of birds and mammals (endothermic animals) is an active adaptation to the environment due to the perfection of thermoregulation.

Human dormancy only exists in certain works of science fiction.

In the movie "Interstellar", astronauts can go to sleep in a dormant waterbed and set their own wake-up time during a long journey in space.

The use of low-temperature hibernation to pass the time is not an original creation of "Interstellar". This technology has appeared in works such as "Alien", "Deep Space Amnesia" and "Three-Body Problem". In The Three-Body Problem, hibernation later became the most common technology for future humans.

Technically, human cryogenic dormancy refers to freezing human beings to minus 196 degrees Celsius in a very short period of time, so that the cells stop their activities and extend the human life cycle infinitely.

In theory, low temperature hibernation can be done.

But from a technical point of view, human beings cannot yet achieve cryogenic hibernation and wake them up.

The main problem is that when the temperature of the human body drops to minus 5 degrees Celsius, the water in the cells freezes and forms ice crystals.These ice crystals can penetrate cell membranes, causing severe tissue damage.

Perhaps in the future this technology may become a reality.There are already several institutions in the world that provide human freezing technology, mainly to provide services for terminally ill people, so that they can be thawed after the problem is overcome in the future.

But in any case, in the current world of human beings, the behavior of entering dormancy at room temperature has never occurred.

Zhang Shan feels that in his current situation, the doctor has restrained himself by not doing slice studies on him~
A little curious look is normal, okay?

Just how should I explain it to the doctor?Should I tell the doctors directly that I have a system in my body, and I need to be down for a while to upgrade the system?
Zhang Shan felt that not only did he not explain the current situation clearly, but he would be transferred to the psychiatric department instead.

It's not impossible, no matter what the doctor asks, just don't know what to say and it's over~
Zhang Shan already regrets that he didn't carefully read the many precautions for system upgrade~
However, it is useless to regret it, so we can only take one step at a time.

~~~
A group of doctors observed for a while~
Soon the leading doctor spoke:

"Mr. Zhang, hello, I'm Director Liang of XXXXXXX. Now your condition is basically fine. You can leave the hospital anytime you want. But do you have time to cooperate with us to carry out some tests?"

Zhang Shan:? ! !
Although I don't know what it is for, but the title is so long, it always feels awesome.

There are also so-called tests.

what test?
"Director Liang, what happened to me before, can you tell me briefly?"

Although he knew what his situation was, Zhang Shan still planned to find out what the doctor thought.

Maybe the doctor didn't consider his situation as dormancy~
After all, there has never been a state of dormancy in human history~
"Mr. Zhang, we preliminarily judge that you are in a light coma due to overwork.

The so-called shallow coma refers to the loss of most of the patient's consciousness, no voluntary movement, no response to sound and light stimuli, painful expressions or defensive reactions such as flinching of limbs in response to painful stimuli.Corneal reflex, pupillary light reflex, eye movement, swallowing reflex, etc. may exist.Breathing, blood pressure, and pulse have no obvious changes..."

Zhang Shan: "Director Liang, now that the situation is clear, which aspect needs to be tested~"

"Mr. Zhang, I'm just curious about your genes~"

???

It is not surprising that women are interested in Zhang Shan's ancestral chromosomes!
But when an old man with gray hair said this face to face, Zhang Shan was in a bad mood!

"Mr. Zhang, it's like this. We conducted some tests on you while you were in a coma, and found that some of your genes were expressed very skillfully, which made us very curious about your genes~"

A woman next to her who looked 30 years old said:
"We found in assays that your gene encoding CCR5 appears to be mutated."

Zhang Shan suddenly became nervous: "What does this mean, is it a disease?"

"Of course not, not only is it not a disease, but it is a good benefit.

With this mutation, your CD4+ T cells cannot express the CCR5 protein.

The HIV virus enters T cells mainly through the "keyhole" of CCR5.Now that the "keyhole" is gone, HIV has no way to enter the cell to replicate and destroy it.

However, this variant occurs frequently in Caucasians (around 10%) but is extremely rare in Asians or Africans.

At present, there is only one cured person in the world -- "Berlin patient". When he suffered from leukemia and underwent bone marrow transplantation, the transplanted bone marrow happened to have this mutant gene.Later, the hiv virus disappeared from his body.
