Zhou Xun went to work, and Zhou Ning was not idle. He visited some local medicine shops and specialty shops around him, and bought some things to study at home.

Zhou Xun came home and saw that he had bought so many things, so he asked, "Do you want to take it home as a souvenir?"

Zhou Ning shook her head, "I didn't tell everyone that I came here, at most I brought some back to Ke Mei's house. It's just that these beef jerky are made of good meat, so I dare not eat them."

Zhou Xun said: "Then don't eat it. When my uncle was still in the state, he took care of these things for a while. At that time, he sent a lot of local products to the family, and they were almost the same things. It shouldn't be a problem. You If you want something with better quality, you can also tell me, and I will ask him to find someone to bring it to you."

Zhou Ning knew that Zhou Xun's uncle worked in the government, but she didn't know what to do, so she asked, "Apart from uncle, do you have any other relatives on your mother's side?"

Zhou Xun said: "My grandfather only has three children, and one aunt who has settled in Canada. She is still unmarried and alone. She is afraid that my mother will say about her, so she always comes back every few years."

Zhou Ning said: "My mother has quite a few brothers and sisters, but I'm not close to them, and I seldom have any contact with them."

Zhou Xun hugged him comfortingly, and said, "From now on, all my relationships will be yours."

Zhou Ning smiled, and then asked Zhou Xun: "Do you know Chuanbei? I bought some. The air quality in City C is poor. I'll take it back to make soup."

Zhou Xun picked up the Chuanbei on the table and identified it for a while. Although he knew that Chuanbei wanted to hold the moon in his arms, he looked left and right without seeing why, so he said: "Chuanbei is a perennial herb. The plant usually has only one stem, and one stem only blooms a flower at the top, and then bears a fritillaria, so fritillaria is less fruitful, so it is rare and expensive, and it is said that fritillary is the smallest fruit that bears at first. The best, and the most expensive to sell. After that, the fruit will grow bigger and bigger every year. The efficacy of the medicine will not be as high as before, and the price will be cheaper. But I know very little about Chinese herbal medicines, so a classmate went to She told me about the food and drug inspection. I can’t guarantee you that this is true, I asked the Chinese medicine teacher who bought us Astragalus before to buy some Chuanbei, and send it back when the time comes, you can use that to make soup.”

In fact, you can also find uncle, uncle's old subordinates, who are now in charge of these things in the state, must have the best things.But these little things, he will never go to him.And there is no major matter to go to him, so Zhou Xun has never asked him for help to solve things, except for calling him to say hello sometimes. Of course, last time his mother went to him to take care of the business except.

Zhou Ning looked at the things she bought, and said, "Then what should I do with these?"

Zhou Xun smiled: "Maybe I will send it to the teacher who makes traditional Chinese medicine to help palm eyes, or just eat it like this, it should be fine."

Zhou Ning also laughed and said, "Forget it. I'm going to make dinner."

Zhou Ning lived in the county for three days, and after spending enough time with Zhou Xun, she went back to City C.

Sometimes there are rare cases of virus or bacterial infection in the hospital. Small hospitals like them have no way to test these samples, or some large hospitals have the ability to do these tests, but they are unwilling to do so because of the rare cases. In order to waste manpower and material resources due to the situation, these samples will be sent to provincial disease control with experts and testing capabilities, and the hospital where he is now will also send these samples, so Zhou Xun and the meeting The driver who sent the samples was familiar with it.It happened that the hospital wanted to send samples to save disease control, so he asked the colleague and the driver who were going to send the samples to help carry two boxes of private goods. Drive to Ke Mei's house to pick up the box.

And Zhou Ning only needs to carry a bag to take the bus back to City C. The things he bought are all in those two boxes. Anyway, they are basically dry goods or cured meat, and it doesn't matter if they can be stored for a few days.

In fact, Zhou Ning didn't want Zhou Xun to bother others, and wanted to take it back to the city by herself, but Zhou Xun felt that those things were too heavy, and it was too troublesome to move them around. It was better for Zhou Ning to drive to get them.

Besides, Zhou Ning had to go to Ke Mei's house to pick up Taotao, so she just picked up her things by the way, it was not troublesome at all.

Zhou Xun gave these reasons, and Zhou Ning said with a smile: "Then why don't you bother Ke Mei?"

Zhou Xun said: "It's okay to bother her a little bit. Anyway, there are some things in the box that were bought for her. She took them home by the way, which saves trouble."

Zhou Xun is always very stable in front of outsiders, and he is very assertive and able to handle things when he encounters things. But in front of Zhou Ning, sometimes he is very childish. Zhou Ning pinches his face, which is regarded as accepting Zhou Xun this arrangement.

Zhou Xun sent Zhou Ning to take the morning bus early in the morning before going to work.

He sent Zhou Ning away with his front foot, but he started thinking about Zhou Ning with his back foot.

Counting the days, there are still nearly 20 days before I can see Zhou Ning, and suddenly I feel unbearable.

He had to let himself divert his attention and devote himself to his work.

At noon that day, other colleagues went home for dinner, and Zhou Xun was the only one who was still in the testing laboratory. After a while, he went to eat at the restaurant where he had been eating lunch.In fact, Zhou Ning wanted to make him a bento for lunch, but Zhou Xun refused because there was no place for hot meals in the laboratory. He didn't want Zhou Ning to be so tired all the time, and it would be too troublesome to cook.

The sun outside is very dazzling, but it will feel a little cold in the laboratory. Zhou Xun took off his white coat and was about to go to eat. Feel hot, hold back.

Maybe Zhou Ning will not get used to it when she returns from such a cool place to such a hot place.Zhou Xun thought so.

Just as he was about to go out, a person who was familiar with the road almost ran into him.

Zhou Xun saw that she was a middle-aged woman, but Zhou Xun had no way to call her a big sister. Once, he picked up a patient and called her "big sister". Later, when he looked at the person's inspection form, the age written on it was only 26. She was many years younger than him, and since then he stopped calling these weather-beaten women "big sisters", but he couldn't call them little sisters or beauties, so he didn't know what to call them.

"Hello, what's the matter, you can't enter here casually." Zhou Xun stopped the visitor.

He forgot who came, but the person who came did not forget him. When he saw him, he said, "Doctor, I sent this for examination. I sent it before, and you were here."

Zhou Xun went to put on gloves to take the sample, read the list again, and then heard the family member chattering, and then he remembered who it was.

It was the one who took her son to see a doctor a few days ago, and her son was infected with salmonella.

Ordinarily, based on the living hygiene habits of the rural people here, her son is infected with salmonella, and other members of the family are also very likely to be infected. However, the immunity of adults is generally higher, and most people will be fine after a few diarrhea. Yes, but children and the elderly have low immunity. After eating something infected with Salmonella, there is a higher probability of diarrhea, abdominal pain, fever, nausea, vomiting, chills, lethargy and other symptoms that cannot be cured, and sometimes death .

Zhou Xun asked, "Is your son alright?"

The woman said: "I went back to take the medicine. I got better yesterday, but today it got worse again. We had to bring him to see him again. It's just diarrhea, why hasn't it been fine."

she complained.

Zhou Xun comforted her and said, "Don't worry, it will be fine. Have you taken the inspection form from last time?"

She said: "I took it. The doctor said that it was infected with something. I don't know much about it."

She took out the inspection form issued by the laboratory department out of her pocket and wanted to show it to Zhou Xun. Zhou Xun said, "Don't show it to me. This report is from me. Your son is infected with salmonella, which is usually at least It takes five or six days to take the medicine to have an effect."

"It's been five days. The doctor in front put my son in the hospital, and we're going through the hospitalization procedures. It's just diarrhea, why is it so troublesome, are you prescribing medicines for us indiscriminately, is there something wrong with the previous medicines?" She keeps complaining.

Zhou Xun said: "This is not a simple diarrhea. He still has a fever, is nauseated and can't eat, and is afraid of the cold and has been sleeping all the time, right?"

The other party saw that Zhou Xun knew things like a god without seeing the patient, so he stopped complaining blindly and said, "Then what's wrong with him."

Zhou Xun said: "Follow what the doctor said first."

"If he looks like this, it is likely that he has become resistant to the drug. It is necessary to change the drug. And it is difficult to deal with fever. It is better to be hospitalized for observation." Zhou Xun asked again, "Except for your son, other people in your family have had stomach problems. Symptoms of abdominal pain and diarrhea?"

The woman said: "How do you know this, maybe it hurts a bit, but I don't care too much, I don't remember it."

Zhou Xun sighed in his heart, and asked again: "Did he eat anything, didn't you eat anything? Like cold bacon, eggs, etc."

The woman said: "There is bacon to eat, and eggs are also for him. He is not in good health, so he needs to make up for it."

Zhou Xun said: "It's likely that he just ate these, but the food was not clean, that's why he got sick like this. Everything you feed him in the future must be cooked and hot, and you have to wash your hands before eating."

After the woman agreed, she left, not knowing if she would remember, or if she would do so.

There was no drug susceptibility test for Salmonella before, but after Zhou Xun went to talk to the patient's doctor, he said that he would do a drug susceptibility test for the patient, and it would be better to use the medicine at that time.

The receiving doctor said: "Drug sensitivity was not included in the order prescribed to them, and if they were given an additional order for drug sensitivity, they might cause trouble. Moreover, the hospital had never done drug sensitivity before, and there was no price. There is no way to make a bill. The medicine he used before is not good, just change it."

Zhou Xun said: "The drug resistance rate of Salmonella is so high now, and many strains are resistant to seven or eight drugs. Let me do it first. There is no need to issue additional inspection sheets for them."

Because no drug resistance test of Salmonella had been carried out before, there was no standing drug-sensitive tablet here, so he had to prescribe various antibiotics. The drug susceptibility test was carried out on the patient's strain isolated and purified in the previous time, and the patient's sample this time was subjected to another isolation test.

Zhou Xun was busy all afternoon and forgot to eat. When other colleagues came to work, he realized that he hadn't eaten yet, so he hurried out to eat a bowl of noodles.

Fortunately, the management here is loose, so he can go out to eat a bowl of noodles. If it was before, he would never go out to eat during working hours.

Zhou Ning called Zhou Xun when she got home in the afternoon, cleaned up the house, went to Ke Mei’s house in the evening to pick up the box and picked up Taotao, and held Taotao and Zhou Xun’s video in the evening, Taotao didn’t look thin , It was about a few days away from Zhou Ning, and he, who had always been arrogant and disdainful to take care of his two-legged beast, lowered his noble head and stuck it in Zhou Ning's arms.

Zhou Xun got the results of the drug susceptibility test on the second day. Unfortunately, the tetracycline, streptomycin, kanamycin, ofloxacin, ciprofloxacin, and gentamicin tested were all resistant. Drugs, only the fourth-generation quinolones and cephalosporins have no resistance.

He fed back the results to the clinical doctor, and the other party took the medicine more confidently.

Afterwards, Zhou Xun did a second sample to isolate and purify the drug resistance of Salmonella, and the result was the same as the first one. After he fed back the results to the receiving doctor, he ignored the matter.

When he went to see the doctor for other matters, he was relieved when he heard that the patient's condition had improved and he had been discharged from the hospital.

In places with difficult conditions, the child's mortality rate is always higher, but no one wants to see a good child leave this world because of this infection, and it is always happy to be able to recover. Zhou Xun even ate an extra bowl of rice at noon that day.

In the evening, while checking the literature and chatting with Zhou Ning on QQ video, he mentioned this matter to Zhou Ning, and Zhou Ning said, "Salmonella infection can be so serious?"

He has no common sense and concepts in this area, so he is very confused.

Zhou Xun said: "The fatality rate is more than 3%, so if you have stomach pain, diarrhea, fever and chills, don't think it's a trivial matter and let it pass. You should go to the hospital for treatment."

Zhou Ning explained clearly, and then asked how to avoid infection, Zhou Xun said with a smile: "Many cooked meat products, eggs and even some fruits are infected with salmonella, so wash your hands before meals, reheat the cooked meat products bought in the supermarket before eating , do not eat raw eggs, wash the fruit well, the problem is not big. In the past, KFC and tomatoes carried salmonella in the United States and caused a large-scale outbreak of salmonellosis in the population. In fact, there are many such cases in China, but many people are infected and do not go to the doctor. , so there are only a few statistical results.”

Zhou Ning was about to be told by Zhou Xun that the obsession with cleanliness was even worse, so Zhou Xun had no choice but to comfort him again. Zhou Ning asked, "Then these situations cannot be controlled?"

"This is the work of disease control. For example, if we admit and treat infected people, they will report to the foodborne disease surveillance system. They can see it from the system, and they will come to collect the bacteria. If there are infected people in the same place at a certain time Multiple infections may represent an outbreak caused by the same strain of bacteria, and they will investigate the source to avoid further infections. Especially schools or large companies with restaurants, if this happens, they will immediately investigate the cause."

"Schools and big companies are okay, but if it is a scattered crowd, how can it be said that there is an epidemic? Can you find out the source?" Zhou Ning was very puzzled.

Zhou Xun said: "Just as people can judge father and son through their genes, so can microorganisms. There are many molecular biology methods that can prove whether the bacteria infected by those people are the same strain, and their genes can also explain the problem."

Zhou Ning smiled and said, "It feels like investigating a case."

"Yes." Zhou Xun said.

Zhou Xun thought that the patient who had been infected with salmonella would not come again. Unexpectedly, within a few days, his mother appeared at the door of the laboratory again. Rushing to the laboratory, Zhou Xun was really helpless to her.

But what is even more helpless is that her son is still the same problem as before.

She sent the sample and said to Zhou Xun worriedly: "They all said that my son has hit a ghost. If the hospital can't cure him anymore, we will go to the Living Buddha."

Zhou Xun said in amazement: "He may have relapsed or repeated infection, don't be superstitious. Isn't your family Han Chinese?"

"It's Han Chinese." The other party said.

Zhou Xun said: "You should still believe in science and hospitals."

The other party's face was full of sadness, and the son's illness was about to overwhelm this woman.

Probably her husband went out to work, and she and her mother-in-law were the only ones at home.

Zhou Xun sympathized with her very much.
