The students were scrambling to go, and Ye Zhenzhen deliberately said: "A business trip is not a tour, especially this time I went to the wild to catch wild mice, which is very hard." ”

"I'm not afraid of hard work, isn't it just catching mice, putting rat cages, rat traps, and sticking rat boards...... I'll do all of that. Yang Fei volunteered to recommend himself.

Gao Fushan said nonchalantly: "No matter how hard it is, can there be a half-buried dead pig? ”

Ye Zhenzhen said with a smile: "In fact, these two situations are equal, although the corpse is disgusting, it is within the controllable range, and in the wild of Huludao in the northeast, there are many snakes, insects, rats and ants, and the situation in the wild is complicated, no more than in the city and in the countryside, it is also very dangerous." ”

Ma Hui is a girl, originally heard Xiao Gao say how to deal with dead pigs and human corpses at the scene of the Sichuan-Streptococcus suis epidemic, and her heart was already disgusted, but now she heard that there are so many dangers in the wild, and she retreated from such a thing as a business trip to the field, "Teacher Ye, you shouldn't need a girl to catch mice in the wild, right?"

"Well, this kind of dangerous physical work is generally not allowed to go to girls, like going to the hospital to collect specimens of death cases, you have to be careful, and it is easy and labor-saving, but you can go. ”

Ma Hui was a graduate student majoring in biology and had never seen a dead person, let alone taken a sample of a dead person, so she couldn't help but ask in horror: "Sampling dead people? Aren't all the case specimens in the hospital taken by doctors? Why should we go?"

Ye Zhenzhen remembered a death case sampling activity she had participated in before, and said: "In some cases, our disease control personnel still need to go to the sampling site in person, so as to facilitate communication and operation. ”

"Teacher Ye, have you ever sampled the dead?" asked Ma Hui curiously.

"Well, I went once, last summer, there was a mad dog bite incident in the suburbs of Beijing, the bite was a fifty-year-old janitor, the old man was just rubbed by the mad dog on the skin on his arm, a little blood, the old man didn't take it seriously, he didn't get the rabies vaccine, a month later, the old man fell ill, admitted to a suburban hospital, and soon died, the doctor suspected that it was rabies, the old man's family wanted to get the diagnosis report, and wanted to file a lawsuit with the mad dog owner for compensation, so I found the Chinese CDC Mr. Nan here, Mr. Nan arranged for me to cooperate with the doctor to sample the deceased。 ”

Yang Fei has a medical background and knows the pathogenesis of rabies, so he asked: "Rabies patients collect saliva and cerebrospinal fluid for examination, what specimens do they need to collect after they die?"

"The gold standard for diagnosing rabies is to isolate the rabies virus from a patient specimen, and the best specimen for virus isolation is brain tissue," explains Yeh. ”

"Teacher Ye, are you going to collect the brain tissue of the deceased?" Ma Hui asked in surprise.

"Well, Mr. Nan discussed with the family of the deceased and reached an agreement to collect the entire brain tissue of the deceased, in addition to giving a detailed examination report, the rest will be studied in our laboratory. ”

Different from Ma Hui's nervousness, Yang Fei asked excitedly: "How do you operate the brain tissue of dead people?

Ye Zhenzhen shook her head, "No, most of them are carried out by doctors in the hospital, and I am an assistant, because at that time, the entire braincase of the deceased was sawed open and the complete brain tissue was taken out, and finally the doctor sutured it again, and from the surface, I couldn't see anything unusual about the deceased." ”

Ye Zhenzhen said it simply, but the whole process is only known to those who have experienced it.

Ma Hui had another fear of sampling the deceased, but Yang Fei sighed thoughtfully: "It doesn't sound so terrifying, it's better than Xiao Gao said to go to the epidemic site to deal with the dead pig carcass, I still want to follow Mr. Nan to Huludao in the northeast to catch wild mice." ”

Gao Fushan also echoed: "I also want to go, after all, I have already had the experience of going out to deal with the epidemic." ”

Ma Hui said on the side: "You all want to go, what about our proposal report?"

According to the previous arrangement, this week there will be a proposal presentation meeting, at which the proposal reports of the new students will be reviewed.

Whether the proposal report can be passed determines whether the freshmen can successfully enter the next experimental stage, and it is also one of the basis materials for the graduation thesis defense committee to review the students' graduation defense qualifications, so everyone attaches great importance to it.

Yang Fei didn't care, "Is there anything that can't pass the proposal report? Isn't every student who enters the laboratory have their own topic?"

Ye Zhenzhen didn't expect Yang Fei to think like this in her heart, thinking that the proposal report was just a formality, this kind of thinking was unacceptable, so she hurriedly corrected it and said: "Although the proposal report can be passed, some people pass it at one time, some people revise it three or four times, or even five, six, seven or eight times before passing, others have entered the mid-term assessment, and some people have passed the proposal report, and they are admitted at the same time, and the difference is so big." ”

Yang Fei asked incredulously: "Really, the opening report will also be stuck, and Teacher Nan's requirements are so strict?"

Ye Zhenzhen explained: "It's not that Mr. Nan is strict, but the proposal report is very important, but don't worry too much, as long as you look at the information carefully, especially the previous research results of the laboratory, and turn those things into your own, so that you can have your own ideas, so that the proposal report will no longer be a problem." ”

Yang Fei seemed to have an understanding, "Oh, it sounds like this, my proposal report has to go back and change it, I hope it can be passed in one time." ”

Gao Fushan also kept it in mind and said: "I will also go back to change it, but the proposal report presentation meeting should be held before going to Huludao in the Northeast, otherwise how would Mr. Nan listen to our proposal report?"

Ye Zhenzhen casually flipped through the desk calendar on the table, it was already early September, because of the Sichuan-Streptococcus suis epidemic, which was delayed for a few days, and the opening report statement meeting must be completed before the eleventh holiday, so the matter of going to Huludao in the northeast to catch wild mice will be pushed back.

Ye Zhenzhen looked at the desk calendar and said: "Teacher Nan will definitely participate in the opening report presentation meeting, as for going to Huludao in the northeast to catch wild mice......

Before the next words could be spoken, a magnetic voice suddenly continued, "Northeast Huludao, I'm not going." ”

Vera Ye and the students looked up at the same time in the direction where the sound was coming from.

Nan Zhiqiao didn't know when he came behind everyone, and he didn't know how much he heard from the conversation just now, and his sudden words surprised everyone.

Ye Zhenzhen was the first to react and asked: "Don't you go to Huludao in the Northeast? Will this year's wild rat hunting activities be canceled?"

"No cancellations, it's just that I'm not going. Nan Zhiqiao explained.

"Who are you going to send?"

Nan Zhiqiao's eyes swept over the students, some expected, some worried, and finally, Nan Zhiqiao's eyes fixed on the two boys who had entered the laboratory this year, and said, "Xiao Yang and Xiao Gao go." ”
