Micro-check

Zhou Xun knew that it was useless to talk about science to this woman. She didn't know what science was at all, maybe she didn't even know how to write these two words.

People live in their own environment. Some people spend their whole lives in a small village, some people live in a bigger world, and some people aim to explore the truth of this world. Some people have power and money, and some people have Culture has knowledge, some people have nothing, in order to survive, it is already extremely difficult.

As the hosts of pathogens in this world, these people are all indistinguishable. If there is any difference, it only comes from the mutation of certain genes, such as differences in cell surface receptors, and from the essence of human beings. On the face of it, there is really no difference.

In terms of sickness, man and man are completely equal before God.However, whether you will be exposed to these pathogenic factors has a lot to do with the environment in which people live, their rights and money, their culture and temperament, and so on.

People who like to have sex with many people are more likely to be infected with microorganisms that cause sexually transmitted diseases; people in nuclear leakage areas are naturally more likely to get cancer; people who have been in smog environments are more likely to develop respiratory diseases The possibility will be even greater... and the woman in front of Zhou Xun's family, because there is not much knowledge and behavior to prevent pathogenic microorganisms or parasite infection, the possibility of infection with pathogenic microorganisms or parasites will be even greater.But even if they were infected with these healing microorganisms or parasites, some people attributed it to a ghost, and died because they did not receive standardized treatment.

But it's useless to talk to them about any scientific things, because they don't have the most basic common sense in this area, so they can't understand.

Zhou Xun said: "I will do a test right away, but the results won't come until tomorrow. Is your son hospitalized?"

The woman said, "I have to live again. It costs money to stay in the hospital all the time, and there is no adult to watch at home."

Zhou Xun said: "As long as it is treated well, there will be no problem. Don't believe in those superstitious practices, or it will really harm your son."

Probably because of Zhou Xun's gentle words, the other party was comforted and went back to the ward.

In fact, there are quite a few patients who send samples for examination every day. As far as their microorganisms are concerned, there are at least a dozen of them. But Zhou Xun is very concerned about that woman, maybe she is too pitiful.

Zhou Xun finished the experiment in the afternoon, talked to his colleagues, and went to Dr. Du, the doctor who prescribes the test sheet, to ask about the patient's condition. The possibility is very high. Control his body temperature and give him antibiotics first, and wait for your test results to come out. But it should still be very likely that Salmonella is present. It’s just that there is still no way to do serotype on your side?”

Dr. Du is a young doctor in his 30s. He is more convinced of Zhou Xun's testing ability and insight, so he is willing to discuss some patients' conditions with him, and even consulted him on some testing issues.It was precisely because the two had more topics to talk about that Zhou Xun came to talk to him.

Laboratory, radiology, ultrasound and other auxiliary departments have always been in the status of second-class citizens in the hospital. Not only do they get less money, but they also have a low status. Many clinicians think highly of themselves and are unwilling to deal with people in these departments. If you respond, most of the time you are bossing around and asking about the result.In particular, some experts and doctors who think they have senior qualifications and high status are not willing to talk to them. Sometimes the test results are ambiguous and it takes time to redo them, which will delay their treatment and medication. It is not new for the testers to be blamed. Of course, the accuracy of the test results is questioned, and it often happens.Not to mention young people like Zhou Xun, Director Wang was pointed at his nose and scolded before. Of course, Director Wang's character naturally scolded back.

Although the status of the laboratory department is now much higher than before with the continuous development of laboratory medicine, the conflict with the clinical departments has not been alleviated too much.

Therefore, if he is not a clinical doctor with a good acquaintance, Zhou Xun will not get along with him to make fun of himself.

Zhou Xun said: "The department did not buy serum for typing. It is too late to buy it now, mainly because the leaders are afraid that they will not approve it. A set still costs tens of thousands."

Dr. Du was also helpless.

Zhou Xun gave a suggestion, "I have kept the bacteria isolated and purified from his samples every time, and kept them in the refrigerator. After this time, I asked the disease control teacher to send them to the provincial disease control department for molecular analysis. I just don’t know if the disease control teacher is willing to send it. One of them has to be responsible for many kinds of diseases. If they are too busy, they probably don’t want to do it. If they are willing to send it, I can save it. While calling, I asked them to help speed up the process, and the results would be available in one day. Molecular typing can best explain the problem, whether it is the same strain or re-infection with other bacteria. But I think the same strain is the most likely.”

Dr. Du said: "This is too troublesome."

Zhou Xun said: "The patient's family seems to have no money, and it is impossible to ask them to pay for these inspections. The CDC needs to monitor food-borne pathogens. I happen to know someone from the provincial CDC who monitors salmonella. Although he is also busy, it shouldn’t be a problem to help bring a few samples. And the patient’s repeated infection is most likely due to repeated exposure to pathogenic bacteria in his home. If the teacher from the disease control side can go to his home to take a sample to see what it is Just let him re-infect."

Dr. Du said, "Are they willing to do this?"

Zhou Xun said: "If you explain the situation clearly, there should be no problem. After all, human life is at stake."

Dr. Du said: "If you have the heart, you can do it."

Seeing that he was busy with other patients, Zhou Xun went to the ward to check on the patient.

The little boy, thin and lifeless, was on an infusion.His mother and grandma watched over him, anxious.His mother was wiping his body according to the doctor's advice, and his grandmother was just holding the beads and begging for God's blessing. She also thought that hospitalization was too expensive and useless. She wanted her daughter-in-law to take the child back. It might be more effective for them to hire someone else. bigger.Zhou Xun is not a person who is good at persuading people, because his way of thinking makes him seldom resonate with others in words, so he stopped persuading, took a few glances and went back to the department.

Patients infected with pathogenic microorganisms will show many symptoms. Before the development of microbiological testing science, clinicians treated according to symptoms. Now, the detection of pathogenic microorganisms is the most accurate judgment standard and evidence.Of course, even with the development of inspection science, many advanced instruments provide many methods for this science, not every pathogenic bacteria can be directly detected.Among them there is the problem of false positives and false negatives. In addition, the samples taken do not contain pathogenic bacteria, or the samples containing pathogenic bacteria cannot be obtained. These problems all exist.

But even so, it has established the important position of microbiological testing in the treatment of diseases caused by pathogenic microorganisms.

This also makes the status of the laboratory department in the hospital no longer as low and embarrassing as before.

However, the latest technology and instruments are used for inspection, which naturally costs a lot of money.

The cheapest way to do genotyping of several Salmonella samples is naturally to design primers and run the gel by yourself. The cost is low, but it takes a lot of energy and time, and the current laboratory has no equipment at all; you can also send samples to the company for testing. Sequencing and then comparing, this process will take a week back and forth, and the price will not be cheap; it takes a short time to do it with ready-made kits, but this hospital does not have kits and instruments at all, and the cost is not high. Less, the cost is about hundreds to thousands, and the patients absolutely cannot afford it.

These fine and more precise tests are based on high-end talents, expensive equipment, and expensive reagent consumables, because patients cannot afford them. Not to mention these small hospitals in the county, many large hospitals in the city have It is impossible to carry out these tasks, and only a few large hospitals will carry out them, and because these projects are basically not covered by medical insurance reimbursement, there will be fewer patients who are willing to do these projects.

Zhou Xun is naturally very clear about these situations, so he thought of other ways to do it.

Zhou Xun was not familiar with the micro-examination staff of the county's CDC, so he had to call the provincial CDC staff to ask about the situation. The inspection staff called Zhou Xun, who called the teacher surnamed Yang. Regarding AIDS, there was no way to help deliver the bacteria, so I called the teacher who wanted to send Mycobacterium tuberculosis to the province to help bring the samples.

Zhou Xun is very grateful. After agreeing, he took the strains that were isolated and purified before and the strains that had not grown well this time to the CDC in the evening, and gave them to the staff who had been waiting for him, and told her to send them to After giving it to someone, he returned home.It is necessary to deliver in the evening because it takes a long time to go to City C by car, and the staff who deliver the samples will leave the house at [-]:[-] the next morning.Zhou Xun didn't want to take the samples to her so early, so he might as well send them over after get off work.

The next day, Zhou Xun went to see Dr. Du and went to see the boy in the ward. His condition had improved and he no longer had a fever, but he still had diarrhea symptoms and had been receiving infusions.

Because the situation has improved, and the nurse has been assuring the patient's mother and grandmother that the medicines prescribed can be reimbursed, the other family restrained themselves and did not leave the hospital directly.

Some patients have no way to communicate at home, they don't want to see a doctor, they don't even go through the discharge procedures, and they don't know the doctor, so they just leave. This kind of situation is not uncommon here.

So they are still there, Zhou Xun is relieved.

At seven o'clock that evening, Zhou Xun had already left work and was at home. He didn't want to eat out, so he cooked the quick-frozen Chaoshou made for him by Zhou Ning at his residence. There were tomato stuffing, lotus root stuffing, and There are coriander and meat stuffing, Zhou Xun likes to eat.

It's just that Zhou Ning's cooking is delicious, and Zhou Xun's cooking is a pot of noodle broth. Although the appearance is not very good, it is not unpalatable to eat.

Li Xi called Zhou Xun and said, "I finished it for you after working overtime. They are all Salmonella typhimurium. After typing, they are the same strain."

"If you want the results there, I will send you a copy for you and Teacher Yang, who is in disease control. You said you want to go to the patient's home for sampling, but you can go there. However, typhoid fever can be carried by domestic animals and mice, and it is easy to get infected in the hospital. And now it is summer, the weather is hot, and it is the season of high incidence of typhoid fever Salmonella, you may divide a lot. If you divide, you should send someone to send it. I also agreed with Teacher Yang, and she said that I will be promoted. Sub-high school, she is short of articles. She will take the sample to the province and we will take her to do it. She has completed her training and can use this case and sample to write an article. Your hospital doesn’t mind. "

After all, it was Zhou Xun who isolated and purified the strains. Teacher Yang wanted to use it for subsequent molecular identification and typing of strains to write an article, so Li Xi naturally had to ask Zhou Xun.

Zhou Xun smiled and said, "Thank you for your willingness to help with the follow-up, why would I mind. Besides, most of the work and money are done by you."

When Zhou Xun went to work the next day, he told Dr. Du about the test results given by the disease control department. He then went to the patient to explain the situation, and expressed his desire to go to their home for pathogenic bacteria testing, and said that the source of infection was detected. After where, pay attention to control in the future, and there will be no re-infection.

The boy's mother was very cooperative and said, "Then are you going now?"

Zhou Xun said: "No, when you leave the hospital, I will take another doctor with you, and we will send you home."

Zhou Xun is likable, and the boy's mother readily agreed.
