Listening to the fat man's shouting, several people turned their heads to look at him, and Xu Yi asked the fat man, "What's wrong?"

The fat man said: "I have seen a lot of scenes on TV that are like this: a group of people go into the mountains or see a heavy snowfall, and then after a while, the people inside shout, 'Why can't I see anything', and then as soon as the camera turns, there are people in white coats, holding medical records, and telling their families with a stern face that this person has snow blindness and may be blind, and the emotional family is really acting!"

Liu Liping heard this, and burst out laughing: "People call this the form of art table, we don't have this kind of disease here, and we are not ophthalmology doctors, so it's not strange to know, not everyone is the same as a monster like the third child." You haven't seen that there are still 800 miles away to knock down the devil with one shot, or tear the devil by hand, I wonder why there are so many strange people and knights, this war of resistance has to be fought for eight years, is the Kuomintang and the Communist Party really soft to this?"

The fat man shook his head: "I haven't watched anti-Japanese war dramas for many years, I'm aesthetically tired of this thing, and I feel sick to my stomach when I see the guns all over the screen." ”

Hu Yifei sighed: "The Anti-Japanese War is a scar in the hearts of the Chinese people, and this low-quality Anti-Japanese War drama is just to repeatedly provoke this scar and make it difficult to heal. What's more, the TV series does not have the function of entertaining and educating, so filming is undoubtedly consuming the patriotic plot of the Chinese people. ”

The fat man nodded: "Yes, but if there is such a bloody TV series, you can directly hang a sign in your heart to the director and screenwriter who filmed this TV series, with two big characters written on it." It's good to see the movies and TV series he makes and writes again, and it's good to stay away, and it's not worth wasting your time for the helpless. Anyway, this is the year when entertainment is paramount. There are more directors who can pant than dogs who can pan, and you are eliminated one by one. Even to death, there are countless films that you haven't even heard of. ”

Hu Yifei said: "In fact, this also reflects the strict zhòng of the phenomenon of following the trend, this taste wants to seek innovation and change, and there are too many unreliable things filmed." ”

Liu Liping covered her mouth, she usually has nothing to do when she watches TV series on the Internet, this topic reminds her of a lot of similar plots, so she said with a smile: "It is still possible to resist the war with millet and rifles, blindly relying on cold weapons such as knives, guns, bows and arrows, is this reliable? In those years, there was no such thing as weapon control, is it so difficult to kill a few devils and upgrade them into guns, and this bow and arrow can be more powerful than a rifle?"

The fat man said in surprise: "Looking at these things, you can analyze this, this IQ is okay? It's just that if this is changed, if you kill all the devils, how will you let others shoot them? Even if you don't have to care about other people's lives and deaths, what if this blocks your way to make a sequel? Don't you know that this TV series also has the saying that raising thieves is self-respecting!"

"Dead fat, you have a problem with your IQ!"

Xu Yi has never had much time and opportunity to look at this. I didn't have much say about this, but I laughed and listened to a few people complaining there, until a few people stopped, and then continued, "The main factor of these lesions must be long-term exposure to large doses of ultraviolet light, which is the basis of lesions." As for whether the amount of salt on the body surface will have a promoting effect on the lesion, I still do not know, these can only be said to be my guesses, and the accuracy needs to be further investigated. I'll look for literature reports to confirm it later. I just don't know if we have relevant materials in the library. Subsequently, Xu Yi continued: "Normal cells still have a certain resistance to a low concentration of salt solution such as soaking in seawater for a short time. Even if it's really the factor I'm talking about, then be careful to rinse it out in time. Coupled with proper protection and reduced exposure time, there may be a lot less sunburn. Of course, if you have photosensitive dermatitis, or those who have a melanin synthesis disorder, you will still get sunburned even if you don't go to the beach. ”

Hearing Xu Yi say this, Liu Liping felt a little strange: "Is there still photosensitive dermatitis, can you still live if you are allergic to light?"

Xu Yi shook his head with a smile: "Actually, it's just because of exposure to ultraviolet rays that the body has allergies, it's not that this person is really allergic to light." The energy level of ultraviolet rays is relatively high, and the ultraviolet rays that penetrate the skin will cause a series of physical and chemical reactions, and some people are allergic to the products of these reactions, so it is called photosensitive dermatitis. ”

"For example, to change the conformation of certain molecules, this can be applied to the treatment of neonatal jaundice. Now, in order to reduce side effects, blue light exposure is used instead, which can make the molecular conformation of bilirubin change, which is easier to be eliminated from the body, so as to quickly reduce the bilirubin in the baby's body. In addition, celery, for example, contains a certain amount of psoralen. ”

Hearing Xu Yi say psoralen, Liu Liping looked up at Xu Yi and wanted to ask him.

When Xu Yi saw her gaze, he naturally knew what she wanted to ask, so he smiled and nodded: "That's right, it's the psoralen that is also contained in the broken paper." This small molecule of furans is not destroyed by cooking and can enter the human body through the digestive tract. ”

"Psoralen is also a photosensitive substance, and the external application of psoralen can make the skin red, swollen and pigmented in the light area, and there are many people who use this property to treat vitiligo. However, some people who are highly sensitive to psoralen will have stricter allergy symptoms after eating celery and then getting exposed to the sun. Babies with porphyria will fluoresce under a specific wavelength of ultraviolet light because their urine contains porphyrins, and babies with porphyria may even be disabled by strong light. ”

Liu Liping nodded: "Oh, I see." ”

Hu Yifei looked at Xu Yi and asked, "Third child, you said this, why don't you seem to have anything in our books?"

Xu Yi said with a smile: "There are still too few people engaged in basic medical research in China, and the content of our textbooks is even more strict and lagging behind. The things on foreign periodicals and magazines are more detailed and in-depth than our domestic research, and there are many foreign academic journals in our library, if you go to borrow them, you will know. ”

The fat man sighed: "The third child has changed his career to be the boss, which is really a big loss to the medical industry." If the third child is in a suitable position, plus enough time, he will definitely become a generation of famous doctors!"

Xu Yi shook his head: "What about famous doctors, even if they are famous doctors these days, don't they have to be restricted by this system? Even if I really stay in the hospital, I'm afraid that I won't be able to do anything other than see a doctor, and even if I don't have this kind of learning environment now, it's hard to say what the level will be in the long run." And it's not profitable, if there is no article, there is no benefit of the research will definitely not be supported by any hospital, if you don't oppose this research and study to occupy working time, it's good, or it's just a mind to drill in the research, strict zhòng out of the clinic, so even famous doctors are often famous, how many famous doctors can't even look at the diseases of related specialties at all?"

Yan Peimin also shook his head: "That's right, after all, money is the first word, if you want to research, you can't do without money, you are out of this sea of suffering, you don't have to think about the job title or anything, wait for me to be miserable, in the future, I can find a research institute or something like that, which is more or less convenient to get funds." This is to find a private enterprise, but I am afraid that this project and money, people have the final say, what results you want to have, it is basically nonsense, I can only hope that the salary and benefits can be more. ”

"Don't be too discouraged, you haven't started reading yet, so you don't have to think about what will happen after graduation so early. If you want to engage in research, you must find a way to enter a state-owned research institution, or at least find a relevant university. There is no need to expect private capital to engage in research, if that is the case, I am afraid that you can only follow the trend to do those jobs that avoid patents to do generic drugs, and it is difficult to have the opportunity to do any research and development work in this life, and it is too difficult to come up with results in the domestic environment. ”

Yan Peimin sighed: "Yes, so I can only take one step at a time, let's wait for the Hu Peel first." ”

Xu Yi looked at a few people, and then said: "Even if I am really at a high level, so what, compared to the patients I treat, there are still more people who cannot be treated because they can't pay the high medical bills. It is impossible for me alone to change the social status quo in which rich people spend money to see a doctor, and those who have no money can only wait for death. If I really agree to go to the attached hospital, I am afraid that this situation will be seen more, and sooner or later I will have to get tired of watching patients die in front of me, but not because of technical problems, but only because of economic factors. At least I went home and only had to treat the people in the village, which could not be solved, and I did not expect to make a profit for a small problem. It can alleviate the problem of difficulty in seeing a doctor in the village, and there will be no such thing as looking down on the doctor in my place. And they have become richer, so they will naturally improve their living conditions, plus they have money to see a doctor, it can be said that this is at least a good thing for the people in the village. ”

After saying this, Xu Yi turned the topic back again, and continued: "As for using saline to make a mask, I can be sure that there will be no adverse reactions. ”

Liu Liping remembered the question that others had said in their previous posts, so she asked: "There are no adverse reactions, so why are some people allergic to this thing?"

Xu Yi smiled and shook his head: "People will never be allergic to normal saline, now that the production technology is so mature, there should be no such thing as bringing pyrogens or antigens into the saline, this is not because they accidentally polluted the saline, or because they added something strange to the saline to make the mask." ”

Liu Liping asked again, "The former is possible, but who would add strange things to the salt water?" (to be continued......)
