In his last life, Li Zheng was not only a professor at Huaqing University, but also the director of the National Institute of Materia Medica. He is no stranger to this medical problem that has raged on the front lines of clinical practice 30 years later.
Li Zheng remembered that a week before his sudden death, the National Ministry of Health of China made a large-scale work report on the issue of "resistant strains" at the National Health Conference, and made it part of the next five-year plan. As a key task, provinces and cities have followed up, and many provincial and municipal health departments have even listed the frequency of antibiotic use as an important indicator for the hospital's year-end assessment.
In Li Zheng's view, this is inevitably a bit overkill. In many large cities and large hospitals, patients with fever below 39 degrees will never hang on to the water, which has led to the strange phenomenon of many patients abandoning large hospitals and crowding into small clinics.
"Crack." Zhang Yuejun put a large box of documents on the table with no effort.
"This is all the materials and manuscripts in Professor Xu's lab."
Li Zheng nodded, flipped through the box, and found a slightly yellowed leather notebook.
This is Xu Mingsheng's project notes. He hastily flipped through it. His preparatory work has been done perfectly. All the materials are classified into categories, and it is clear which materials can lead to what conclusions. This provided great convenience for Li Zheng's subsequent work.
"The sample from the hospital hasn't been delivered yet?" Li Zheng looked at his watch, frowning even tighter.
It was already nine-thirty in the evening, and the sleet and snow hit the glass windows of the laboratory, making a light tapping sound.
"I told the security guard when I just came in, and someone will call as soon as they come."
Li Zheng pursed his lips. He put the notebook in his hand on the table, took off his lab coat, put on his coat and held an umbrella and ran into the rain. Precious, he was not used to sitting in the laboratory and waiting.
"Hey, Li Zheng, I'll go with you!" Zhang Yuejun shouted from behind, and quickly followed after he put on a raincoat without changing his clothes.
Hong Kong implements a capitalist system. The capitalist system attaches great importance to the protection of private property. However, because of this, the urban construction of Hong Kong is not as good as the inland of later generations. Because most of the land in Xiangjiang is private, you have to pay rent to the owner of the land on time every month if you want to set up a street lamp on it, so the infrastructure in many parts of Xiangjiang is not commensurate with its prosperous economy.
For example, on the road from Qingyuan to the city center, there are very few street lights, and in the cold and dark night, only a little dim yellow in the distance gives people hope.
Li Zheng and Zhang Yuejun walked for about ten minutes when they saw a person in the rain and snow holding a flashlight in one hand and a large cardboard box in the other.
The cardboard box was already a little wet, and the little girl was lying on the cardboard box almost all over, blocking the rain and snow with her body.
The white nurse uniform was particularly conspicuous in the dark night, and Li Zheng stepped forward quickly.
"People from Mary's Hospital?" he asked.
The little girl raised her head when she heard the words, her body still kept the shape covering the whole cardboard box, and the whole person showed a funny shape.
"I'm Li Zheng."
"Are you Mr. Li Zheng?"
The little girl called out in surprise, "I'm sorry, I sent the sample to the airport first, and it's a bit late when I come here."
Queen Mary Hospital discovered the first case of drug-resistant strain infection two days ago, but because drug-resistant strain infection is a very rare phenomenon in Hong Kong, the hospital did not pay enough attention, and only asked the cleaning auntie Strengthen disinfection.
It was not until a large-scale outbreak of drug-resistant strains in the hospital that doctors found papers on drug-resistant strains by scholars in international journals. The moment they saw the papers, the doctors broke down in a cold sweat.
According to the instructions of the British General Hospital, Queen Mary Hospital immediately blocked the hospital to avoid the further spread of drug-resistant strains, but for those in the hospital, especially those whose inflammation had not completely subsided shortly after the operation, this was a A test of life.
Li Zheng took the box from the little girl, he took off his jacket and covered it on the cardboard box, and then said to the little girl: "Come on, come to my laboratory and drink a cup of hot water, otherwise you will have another drug-resistant bacteria when you go back. of infected people.”
Saying that, he quickly ran to the laboratory holding the cardboard box.
The little girl was already wet, but the information in the carton was really good, and she was not wet at all.
Zhang Yuejun looked at Li Zheng's slightly thin back without a coat, and felt an indescribable feeling in his heart, as if there was an extremely warm emotion in his heart that was about to burst out all at once.
He trotted all the way to keep up. When he ran into the laboratory, Li Zheng had already put the sample into the culture tank.
"Isolation measures are taken before entering." Li Zheng said without raising his head when he heard the voice at the door.
The drug resistance mechanism of bacteria is very complex. The production of antibiotic inactivating enzymes and the change of the target of antibiotics. It is definitely not an easy task to try one by one antibiotics and find a suitable one.
If it is a multi-drug resistant bacterial infection... Li Zheng's hand holding the test tube is tight, then the existing antibiotics may not be able to play a role.
"Zhang Yuejun, all the antibacterial drugs are classified into lactams, aminoglycosides, macrolides, tetracyclines, lincomycins, etc. We will try them one by one slowly." Li Zheng said.
Repeated attempts, this is a boring and untechnical thing. Li Zheng has not done similar work himself for a long time, but in front of life, there are no honorary professors, research institute deans, pharmaceutical geniuses, only one effort A man who races against death.
When you focus on doing one thing, time will pass very fast, and before you know it, it is already bright.
Zheng Lingling and a few classmates slowly walked towards Qingyuan.
"Okay, just take a look. If Li Zheng is doing an experiment, you must not go in and disturb." Zheng Lingling couldn't help but reminded again, seeing everyone looking around.
After the opening ceremony of Qingyuan, Li Zheng has not returned to the school to take classes, but the news that he has a private laboratory has long been rumored in Hong Kong University.
The classmates are still studying hard for the qualifications to enter the laboratory. A new transfer student actually has his own laboratory, and the news praised the advanced equipment of Li Zheng's laboratory, the beautiful environment, and the faint Putting it on top of an existing biomedical laboratory will naturally attract the attention of insiders.
Li Zheng's classmates, although they haven't graduated yet, are still insiders. In line with the principle of satisfying curiosity, the students quickly targeted Zheng Lingling, who was recruited by Li Zheng.
"This is actually a laboratory! This is a villa area!" A girl couldn't help but exclaimed.
"This used to be a villa area. Because it's close to the school, my mother planned to buy a set for me here. Unfortunately, half of the villa was built, and the developer went bankrupt."
"No. 1 and No. 2 are Li Zheng's own laboratory. No. 3, No. 4, No. 5 are still empty." Zheng Lingling introduced to the crowd.
"Alright, just take a look." Zheng Lingling emphasized again.
Seeing everyone nodding, Zheng Lingling timidly led the person to the No. 2 laboratory, but it was strange that there was no one in the No. 2 laboratory.
Is it in Lab 1? But didn't Li Zheng say that he would only go to the No. 1 laboratory if he did work on vaccines, bacteria, and viruses.
"Lingling, I saw an initiative from the student union this morning. It's not the flu outbreak, and there aren't enough medical staff. Students from our medical school can definitely volunteer." A girl suddenly said.
It is customary for medical students to volunteer in hospitals, especially for medical students, it is almost mandatory.
Zheng Lingling's brows furrowed. She is indeed a member of the student union, but now she has a job and a boss. She can't use Li Zheng's salary to do other things.
"You can ask Li Zheng to go with you." When the girl said this, a blush quickly appeared on her cheeks.
Zheng Lingling…
Don't think she's stupid, she also has a boyfriend, can't see the girl's mind
Zheng Lingling shrugged, "You are trying to invite me." Although she only worked in the laboratory for a few days, Zheng Lingling fully understood the essence of Li Zheng, that person is a workaholic.
She felt that it was entirely possible for Li Zheng to spend the rest of his life with the laboratory.
The girl lowered her head and said nothing.
In front of Laboratory No. 1, Zheng Lingling pushed open the door and went in. As soon as she stepped into her right leg, she heard a serious voice inside.
"Change clothes, wear a mask, and take protective measures!"
Zheng Lingling was stunned, only to realize that there were actually three people in the laboratory. Li Zheng and Zhang Yuejun kept repeating and mixing movements, while the other kept writing and drawing on their notebooks.
Is this an experiment
She immediately changed into a white coat and put on a mask. Even if she couldn't get started, it would be fine if she had experienced eye addiction.
The rest of the classmates looked at each other and saw that Li Zheng didn't mean to greet them at all, so they couldn't help feeling a little unhappy. After a few points, they became proud. So many classmates came together without even saying hello.
Classmates, look at me, I look at you, with a hint of embarrassment on her face, the girl who spoke earlier, with the encouragement of her companions, said: "Li Zheng, now that the flu is breaking out, the major hospitals in Xiangjiang are enduring the lack, we plan to go to Are you interested in being a volunteer?"
"Tetracyclines can be ruled out, and the response of drug-resistant strains is so weak that it can be ignored." Li Zheng said to Zhang Yuejun, while drawing a big cross on the word tetracyclines on the notebook.
