medical road with you

Chapter 84
In the next three months, Song Tianwen often brought some samples for them to test. Lu Ping and Yue Jin were busy designing primers and doing experiments every day. Now Lu Ping could go through the experimental process with his eyes closed.

And Song Tianwen, except for sending samples, hardly stayed in the laboratory, and asked Yuejin for advice on what Lu Ping didn't understand. Rather than saying that Song Tianwen was Lu Ping's mentor, it would be better to say that Yuejin was her mentor.

Doing the same thing every day for three months in a row would make most people feel bored, but Lu Ping didn't.Although they are all PCRs, there are still differences between testing a certain gene of a virus and testing a human cancer gene or a certain genetic disease gene.

After careful observation, Lu Ping finally found that the amplification rate of viral genes was significantly higher than that of a certain gene in human cells.

In fact, this is also easy to explain. The genetic material of viruses is seldom very simple, just piled up loosely, while the genetic material DNA of human beings undergoes helical, supercoiled, coiled and compressed, and finally forms dense chromosomes.

The spatial structure differs so much, so the process of denaturation, extension and renaturation naturally also differs a lot.

However, every start-up procedure of the current PCR instrument is the same.

Can you design a set of gene amplification procedures specifically for viruses, and make some adjustments to the reaction steps of denaturation-annealing-extension, at least to shorten the experimental time.

At present, a PCR process takes about two to three hours. It is very meaningful to reduce the time by half by improving the technology and greatly improve the efficiency.

Looking at a pile of data in the computer, this idea came to Lu Ping's mind.

This is the difference between Lu Ping and ordinary people. When ordinary people face repetitive and tedious work, they tend to feel bored and their attitude becomes more and more perfunctory. However, Lu Ping can find something different from this seemingly repetitive and boring work.

Just like the physical examination at Huaguang Hospital back then, others were already impatient, but Lu Ping was able to discover some patterns.

Lu Ping has been working in the laboratory for almost three months. During the three months, Lu Ping will work overtime for eight out of ten days, and every time he works overtime, Tianhai will accompany Lu Ping to work overtime.

On this day, at 09:30 in the evening, Lu Ping and Tianhai drove home together.

On the way, Lu Ping told Tianhai what he thought about during the day.

Tianhai did not comment first, but asked: "You have been in the laboratory for three months, what do you do every day?"

"PCR!"

"PCR, is it possible that you only do PCR every day, and your instructor won't teach you some new scientific research techniques?"

Now Lu Ping does PCR by Tianhai's ear every day, and Tianhai has some understanding of this technology.

Lu Ping didn't think too much about it, and replied honestly: "Teacher Song comes here occasionally to send a sample, and rarely stays in the laboratory."

Tianhai's face darkened: "Your mentor is really good enough."

"You haven't told me what you think of me?"

"Don't worry, I'll check the information first when I get home!"

When he got home, Lu Ping went to wash up, but Tianhai took out his notebook and searched for Song Tianwen.

There is an introduction in the encyclopedia, a professor of virology at Huada School of Medicine, who is good at PCR technology, a normal introduction, no problem.

Tianhai thought for a while, and then searched for PCR testing laboratories. Large medical institutions and scientific research institutions have such laboratories, but there are also many small private companies that also provide PCR testing technology. These small companies will have poorer medical conditions than those in remote areas. cooperation with small hospitals.In this way, small hospitals claim to have PCR technology that can detect XXX, and those small companies can also benefit from it, and patients can also get the medical services they want. It can be said that all three parties are beneficial, but how can these small companies have PCR experiments? room?

To know that the establishment of a PCR laboratory requires high conditions, what is behind these small companies?
Tianhai thought for a while, clicked on the link of a small company, and found the company's legal representative, Lu Chuan.

Lu Chuan?Having never heard of this person, Tianhai clicked on the link of another small company, still Lu Chuan!

The third one was Lu Chuan!
Tianhai frowned, clicked on Song Tianwen's personal introduction again, looked up his resume, Weibo account, and finally found a clue from a casual Weibo record.

Lu Chuan is Song Tianwen's wife!

No wonder Lu Ping had to work overtime all day long. It turned out that his tutor was doing free labor and making money for others.

This Song Tianwen, using the school's resources and using his own students for personal gain, is too abominable!

Tianhai clenched his fists in anger when he thought about it!
"What are you looking at?"

After washing, Lu Ping moved to Tianhai's computer, and Tianhai closed the computer calmly.

"Pingping, your first year of research is almost over, have you ever thought about when you will start your subject?"

"I haven't thought about it yet. People say that it is usually a second-year research topic."

Tianhai couldn't help but support his forehead, his wife is really naive and simple, after thinking about it, Tianhai said to Lu Ping: "Pingping, the note you gave me today is quite good, if it is a very good topic for your graduate thesis of."

"You think my idea is good?" Lu Ping's eyes lit up, and his focus was only on this.

Tianhai put on a serious attitude: "Pingping, listen to me and tell you well. Tomorrow, you will go to your tutor to discuss it, tell him that you want to start a project, and tell him your ideas, but Remember, don't get too specific, just mention it roughly!"

"Oh, okay." Lu Ping didn't think too much about it!
Seeing that his wife hadn't grasped the key point, Tianhai confessed again: "Also, I need to tell your tutor, because you are going to open a project, and it will take some time to do some research in this area, so tell him, I hope there will be less lab work!"

Lu Ping still had no sense: "Why do you want to reduce the work in the laboratory, I really like doing experiments in the laboratory!"

Tianhai was really speechless, his wife was being sold at this time, and she was happy to help count the money. With his face, Tianhai showed a lesson tone: "You work overtime until ninety o'clock every day. You don't feel sorry for yourself, but I do. Woolen cloth!"

If Lu Ping took overtime for her own research, Tianhai would admit it, but she is making money for others, and she has no salary yet!
As soon as Tianhai got angry, Lu Ping immediately gave up: "Okay, I got it, husband, I'll talk to my tutor tomorrow."

Seeing Lu Ping's aggrieved look, Tianhai felt distressed again, took Lu Ping over, gently stroked her hair and comforted her: "Hey, I love you, and now that you have your own research direction, you must It took a lot of energy."

Lu Ping nodded obediently: "Well, my husband, I understand!"

Hey, Tianhai couldn't help but sigh in his heart!As long as there is a way, Tianhai doesn't want Lu Ping to follow this Song Tianwen anymore, but he has been following Song Tianwen for almost a year, so this is the only way to go!I hope that Lu Ping can start the project smoothly and finish the thesis graduation soon!

**
When he arrived at the school the next day, Lu Ping didn't go to the laboratory, but went directly to Song Tianwen's office.Since you feel that you need to start a project, you should discuss it with your tutor early.

Unexpectedly, there were other people in the office.

"I don't care, now, you must let me start a subject immediately. My second year of graduate school is almost over. If I don't start a subject, my graduation may be delayed!"

It was the sound of Yue Jin. Lu Ping's hand that was going to knock on the door hung in the air, and he raised his ears to listen to the corner of the wall.

"You don't have a good direction yourself, and you blame me for not giving you a class!" Song Tianwen's tone was also very bad!
"You force me to do the test for you all day long, how can I have time to study the direction!"

"If you don't work hard, you will be relying on others!"

"Song Tianwen, I know that you have been delaying in helping me with the project because you want me to give you a free job for one more year. I have already investigated what you did. If you force me again, I will report it to the school. I have also found out about your use of power for personal gain and your falsified papers!"

"You, are you threatening me?" Song Tianwen's voice was somewhat sinister.

"Anyway, I don't expect my graduate student to graduate smoothly. We're going to die!"

"Okay, Yue Jin, have you improved your skills today?"

Lu Ping strained his ears to continue listening, when he heard Song Tianwen yell loudly: "Who's outside?"

Lu Ping was startled, and knocked on the door quickly: "Mr. Song, can I come in?"

"Come in!"

Lu Ping pushed the door open, saw Yue Jin, and pretended to be surprised: "Hey, senior brother, are you here?"

Yue Jin hummed and ignored her.

"What do you want from me?" Song Tianwen said impatiently.

"Teacher Song, do I want to start a project?" Lu Ping cut to the chase.

As soon as Song Tianwen heard the word subject, he felt a headache, what happened today, one or two had to start a subject.

Suppressing his dissatisfaction, Song Tianwen asked, "Do you have any direction?"

"There is."

As soon as he heard it, Song Tianwen's expression softened immediately: "Which direction is it, tell me."

Lu Ping roughly explained his thoughts to Song Tianwen. After listening to it, Song Tianwen exclaimed, "Yes, this idea is good!"

After finishing speaking, he looked at Yuejin again, his eyes flickering: "Lu Ping, it happens that your brother Yue also wants to conduct more in-depth research in this area, why don't you two conduct research in this direction together."

Hearing what Song Tianwen said, Yue Jin was taken aback for a moment, and then looked up at Song Tianwen. Song Tianwen gave him a hard look, and then nodded meaningfully. Yue Jin understood what Song Tianwen meant, and struggled in his heart , finally nodded.

Lu Ping was not so thoughtful, and agreed on the spot: "Okay, Senior Brother Yue, please give me more advice in the future."

Thinking of Tianhai's instruction, Lu Ping said one more sentence: "By the way, Teacher Song, there is one more thing."

"what's up?"

"It's just that my family has some troubles recently, so I can't work overtime as frequently as before."

Song Tianwen's face darkened again when he heard it, but when he thought of someone reporting him to use the school's resources for personal gain yesterday, he thought about it and decided to restrain himself a bit recently, so he nodded: "Okay, I understand, since there is something at home , go home early and settle the matter."

Lu Ping didn't expect it to go so smoothly, and replied with a smile: "Thank you, Teacher Song!"

As soon as he returned to the laboratory, Yue Jin asked Lu Ping: "Junior Sister, how did you come up with the direction of the subject?"

Lu Ping pointed to a pile of data in front of the computer and said, look, I compared the results of virus genes with the results of detection of human cancer genes and analyzed them. Is there a big difference? I thought of this research direction.

Looking at the carefully sorted data, Yue Jin suddenly felt very guilty. Lu Ping sat at the same job every day like him. Lu Pingneng had a whim, why he didn't do it.

Thinking that Song Tianwen would let him steal Lu Ping's subject, Yue Jin felt uncomfortable, but thinking of the possibility of delaying his graduation, Yue Jin swallowed the words again.

"Lu Ping, do you know why Professor Song suddenly found you as his graduate student?" Yue Jin asked suddenly.

"Because I want to major in viruses, the professor happens to be studying this direction!"

Yue Jin looked at Lu Ping's innocent face, and couldn't help worrying, so he said: "That's because a graduate student he brought up before couldn't stand his style, so he gave up his graduate degree directly. He found you because he was short of staff."

Lu Ping looked at Yue Jin with puzzled eyes, not understanding what he wanted to say.

Yue Jin simply put it more bluntly: "Song Tianwen is not a good person, you'd better be careful."

"Oh!" Lu Ping nodded half-understanding.

With the research direction in mind, the spirit came in: "Let's finish testing the remaining samples as soon as possible, and then start the research on the subject."

"it is good!"

The two put on their lab coats and gloves, and got to work again.

At six o'clock in the evening, there was one left to be tested.

"Didn't you have something to do at home, you go back first and I'll finish the last one." Yue Jin was suddenly very active.

Thinking of Tianhai's instructions, Lu Ping smiled and said, "Well, thanks for your hard work, brother, I'll go back first."

As soon as Lu Ping opened the door, Tianhai arrived.

"Don't you have to work overtime today?"

"no need!"

"Did you tell me everything I asked you to say yesterday?" Tianhai asked again.

"Well, it's all said."

"Well, good boy, let's go, go home and treat you well."

I've been eating food outside recently, and Tianhai is a little tired of eating, so I'm going home to make a good meal today.

"Honey, have you learned how to cook again?" Lu Ping asked while holding Tianhai's arm.

Tianhai nodded Lu Ping's little nose: "You will know when you get home."

"Do you need me to help you?"

"Okay!"

Washing vegetables, chopping vegetables, mincing meat, kneading noodles, the two of them worked hard for more than an hour, and finally made a pot of fried noodles.

White mung bean sprouts, yellow carrot shreds, green cucumber shreds, chewy noodles, topped with delicious meat sauce, wow, just smelling it makes Lu Ping's mouth water.

With a sound of 'suction', Lu Ping took a big mouthful of noodles, dipping his mouth in brown sauce.

"Honey, it's delicious, it's so delicious! You're amazing." Lu Ping agreed with noodles in his mouth.

Hearing Lu Ping's ambiguous voice, Tianhai smiled and patted Lu Ping's head: "Good boy, eat well."

Picking up a few noodles, Tianhai took small bites, without the sound of sucking, and the sauce wouldn't fly everywhere.

Lu Ping couldn't help feeling that no matter how many years passed, people's habits would never change. The way Tianhai eats Zhajiang now is exactly the same as when he ate the bowl of noodles with clear soup and water.

After drinking and eating enough, Lu Ping turned on the desktop computer and began to look up information.

"What are you looking at?" After a while, Tianhai came over.

"I'm going to start researching that topic tomorrow. I'll check if anyone has already done research on it?"

"Well, don't be in a hurry." Tianhai said, taking Lu Ping's hand off the mouse and putting it in his palm to play with.

Lu Ping sensed something was wrong with Tianhai, and asked, "Tianhai, what's wrong?"

Tianhai looked aggrieved: "Honey, don't you think you've neglected me a little bit lately?"

Lu Ping tilted his head and thought, is there any? Recently they went to work together in the morning, and they would spare time to chat with him for a while at noon, and they also went home together in the evening. Except for the time in the laboratory, she stayed beside him. How could this suddenly happen to him?
Seeing Lu Ping's stupid look, Tianhai was angry and funny, and nodded her forehead suddenly: "I ask you, what day is today?"
