Wang Lin and Zheng Yajun have been good friends since childhood. Although they are married now, they still see each other frequently. At the beginning of the new semester, Zheng Yajun's baby son is 4 years old. Zheng Yajun wants Pangpang to go to Cambridge Kindergarten, which is far from home but with good education quality. But to register, people refused to accept it on the grounds that they were not children in the jurisdiction. When Wang Lin invited Zheng Yajun for a drink, he was worried. During the dinner, Zheng Yajun told Wang Lin about his sadness. I didn't expect Wang Lin to say that he could solve the problem of Xiaopang entering the park. It turns out that Wang Lin's sister-in-law is the kindergarten teacher. Through her, Pangpang finally entered the kindergarten smoothly.
On New Year's Day, Zheng Yajun Branch gave each employee a box of high-quality herring. In order to thank Wang Lin, Zheng Yajun gave the box of herring to Wang Lin intact.
One night a week after this happened, Zheng Yajun came home from work and just walked to his own corridor when he suddenly saw two people in police uniforms standing in front of his house. When they saw Zheng Yajun, they quickly stepped forward and confirmed that it was Zheng Yajun in front of them. They showed their work permit and said they had something to investigate and would take him to the police station. To the police station, Zheng Yajun just know, friend wang Lin died at noon. The hospital diagnosed the death as eating herring. The herring that Wang Lin ate was given to them by Zheng Yajun a week ago. Hearing Wang Lin's death letter, Zheng Yajun was shocked and heartbroken. But when the police said that Wang Lin's death was due to eating the herring he sent, Zheng Yajun was shocked. Zheng Yajun was very wronged. He didn't even leave a herring, let alone unpack it, and sent it directly to Wang Lin. Unexpectedly, how did Wang Lin die when he kindly sent herring? Zheng Yajun reflected the whole process of sending fish to the police. The police said that asking Zheng Yajun to help Zheng Yajun investigate did not mean that he was the murderer, because the direct cause of Wang Lin's death was eating herring, and the box of herring was indeed sent by Zheng Yajun. Zheng Yajun told everything he knew. However, the police did not let Zheng Yajun go home.
A day later, the police told Zheng Yajun that the investigation into Wang Lin's death showed that although she still ate herring, it had nothing to do with Zheng Yajun. Zheng Yajun's suspicion of murdering his best friend has been cleared, and he can go home freely. After being free, Zheng Yajun's heart was not relaxed. First of all, he was sad to lose a good friend, and at the same time, Wang Lin died because he ate the herring he sent. Zheng Yajun always feels bumpy and uncomfortable. So, he took the opportunity to visit Wang Lin's family and met Wang Lin's daughter-in-law. He wants to find out the cause of Wang Lin's death.
Through the story of Wang Lin's daughter-in-law, Zheng Yajun finally knew the cause of Wang Lin's death. Since Zheng Yajun sent the box of herring, Wang Lin, who likes cooking, learned the skills of making ketchup herring with another chef friend. It happened that Wang Lin's company had a holiday that day, so he happily cooked a whole plate of herring in tomato sauce at home. After the herring in tomato sauce was cooked, he originally wanted to share food with his wife, but her colleague in the company suddenly fell ill that day, and her enthusiastic daughter-in-law Wang Lin didn't come home for dinner. Wang Lin enjoys food alone. Unexpectedly, about 20 minutes after Wang Lin finished eating, he called his wife and said that his face had grown a lot of pimples, which made him itch, his heart beat, he was flustered, he couldn't breathe and he wanted to vomit. Wang Lin's daughter-in-law is busy contacting a colleague with an expert she knows. When she heard Wang Lin's phone call, she asked him to come to the hospital himself and said that she was in the hospital. Wang Lin's daughter-in-law finished and went to work again. It has been an hour since my colleague's mother was admitted to the hospital. Wang Lin's daughter-in-law suddenly remembered a phone call from Wang Lin. Call Wang Lin at once, but no one answers the phone. Wang Lin's daughter-in-law immediately took a taxi home and pushed the door open. She found Wang Lin lying on the floor of the living room, her face flushed, and she vomited some food on the floor. Wang Lin's daughter-in-law panicked and hugged Wang Lin, shouting and screaming. Wang Lin was still breathing and asked her for help. He eats herring. Wang Lin's daughter-in-law immediately called an ambulance. However, when Wang Lin was taken to the hospital, Wang Lin had died before the doctor could rescue him. Wang Lin's daughter-in-law doesn't know how her husband, who was fine in the morning, suddenly died in the morning. She was puzzled and thought that when she met Wang Lin, Wang Lin told him that she had eaten herring. Wang Lin's daughter-in-law thinks that perhaps herring is poisonous. I told the doctor that the doctor was diagnosing Wang Lin's death, and this situation reflected by Wang Lin's daughter-in-law caught their attention. They also believe that Wang Lin's death is related to herring. Associated with the source of herring, Wang Lin's daughter-in-law immediately went to the police station to report the case, so there was a scene in which Zheng Yajun was brought back to the police station for investigation.
But why did the police quickly eliminate Zheng Yajun's suspicion? It turned out that through the unremitting efforts of doctors, Wang Lin's death was finally found out. It turned out that Wang Lin was unfortunately infected with tuberculosis in the spring. In order to treat this infectious disease, Wang Lin has been taking first-line anti-tuberculosis drugs such as rifampicin and isoniazid according to the doctor's advice. And isoniazid, a drug, has a good effect of killing mycobacterium tuberculosis, but it also has many side effects, and even has a taboo that can kill people, that is, you must not eat with marine fish while taking isoniazid. Because the content of histamine in marine fish animals such as sardines, herring and tuna is high, isoniazid can inhibit monoamine oxidase, which makes histamine difficult to decompose. If you eat this sea fish while taking isoniazid, you will have symptoms of histamine poisoning. If such patients can be treated in time at the early stage of eating, they will not be life-threatening. But Wang Lin stayed at home too long, so he lost his life. Knowing the real cause of Wang Lin's death, Zheng Yajun felt more guilty and guilty. Although he didn't murder his best friend, Wang Lin wouldn't have left this world early if he hadn't sent the box of deadly herring himself.
In regret, Zheng Yajun also began to hate the doctor who treated Wang Lin. He once went to Wang Lin's attending doctor and asked him why he had such a serious taboo to take isoniazid. Why did he tell the patient when he prescribed medicine as a doctor? In the face of Zheng Yajun's criticism, the doctor seems innocent. He said, after all, this is a case, because he has never encountered such a thing in his medical experience. And he doesn't know that taking isoniazid is taboo and he can't eat herring with him. If even doctors don't know about such contraindications, what about ordinary people without medical knowledge? Is it more likely to lose your life because of ignorance? Zheng Yajun decided to teach himself medical knowledge. Through research, he learned for the first time that when taking isoniazid, he could not only eat fish food, but also know that he could not drink red wine and cheese.
