"We are very concerned about the Omicron cases imported from abroad in China. According to the epidemic theory of traditional Chinese medicine for thousands of years, we still need to grasp the core pathogenesis and symptom evolution law of the disease, and carry out syndrome differentiation and treatment in combination with the onset season, region and people's physical characteristics." Novel coronavirus pneumonia was launched in December in December 16th. The State Administration of traditional Chinese medicine should be the deputy head of the group of experts, the vice president of Guangzhou University of Chinese Medicine and vice president of Guangdong Province Traditional Chinese Medical Hospital, Zhang Zhongde, who is the leading group of the new crown pneumonia epidemic prevention and control work. Zhang Zhongde said that recently, new mutant strains have an epidemic trend abroad. Traditional Chinese medicine has its mechanism for the typing and treatment of epidemic diseases. At present, the main clinical manifestations of the disease are still being collected. According to the theoretical system of traditional Chinese medicine, if there is a patient, the doctor will go to the scene to collect clinical symptoms at the first time, analyze the core pathogenesis, and according to the symptom law after collection, Only by looking at the differences with the past can we determine the treatment principles and prescription drugs. "Practice shows that traditional Chinese medicine has a good effect on the light and common types of people infected with delta variant strain, and also has a certain effect on blocking severe cases." Zhang Zhongde said. Zhang Zhongde introduced that it was clinically found that the proportion of fever among infected people with delta variant virus was more than 80%, mainly including high fever, cold aversion, headache, dry throat, fatigue, abdominal distention, loss of appetite and other symptoms. Severe patients had obvious symptoms of acute deficiency such as asthma, hypoxia and sweating, and the proportion was relatively high. After in-depth discussion and comprehensive analysis, the expert group concluded that the current round of epidemic situation still belongs to damp toxin depression, and the core etiology and pathogenesis of traditional Chinese medicine have not changed greatly. Only due to different factors such as region, climate and eating habits, there are differences in symptom characteristics, different emphasis points of damp heat, as well as cold, heat, dryness and silt, Clinically, it is also in line with the viewpoint of "three factors and measures" of traditional Chinese medicine. For example, the symptoms of diarrhea, vomiting and nausea are more obvious in patients in Xiamen and Putian, Fujian, and the dampness evil is more serious, which is related to region and eating habits. The symptoms of dry cough, dry throat, dry mouth and pharyngeal itching in patients in Northwest China such as Gansu are obvious, which is in line with the performance of "dryness evil invading the lung". Therefore, according to the viewpoint of "three factors and measures" of traditional Chinese medicine, all localities can distinguish symptoms, treat diseases and adjust treatment appropriately on the basis of the original "three drugs and three parties" in the eighth edition. Severe patients were treated with ginseng early and whole course. At the same time, we should also pay attention to the simultaneous treatment of lung and intestines and regulating intestines to treat the lung. Patients with obstructed stool should reuse rhubarb to keep the stool unobstructed. "Traditional Chinese medicine is still very effective in treating people infected with delta virus." Zhang Zhongde said, for example, 166 local cases were treated during the epidemic in Guangzhou from May to June. Among them, 118 patients were treated with traditional Chinese medicine alone, accounting for more than 71%, which successfully blocked the transformation of 57 patients with severe tendency to severe. Zhang Zhongde stressed that traditional Chinese medicine has the characteristics and advantages of multi-component, multi link and multi-target in the treatment of diseases. In the clinical diagnosis and treatment of diseases, traditional Chinese medicine needs to analyze and summarize the main symptoms and characteristics of patients. The most important thing is to find the core pathogenesis of the disease and determine the treatment plan. Novel coronavirus pneumonia has played a unique role in fighting against new crown pneumonia. How can we explain its mechanism and mechanism? In response, Zhang Weidong of Naval Military Medical University responded that with the support of many national projects, it has carried out a large number of basic research and adopted many modern means in the mechanism research at the molecular, cellular and animal levels. For example, in the mild stage, we can see that traditional Chinese medicine has a good effect on cough, fever and fatigue. What is the mechanism behind it? Further research found that "three drugs and three prescriptions" in mild disease stage can improve body immunity. In the critical stage, because of the over immunity of COVID-19 and the emergence of an "inflammatory storm", Chinese medicine can regulate the inflammatory storm and inhibit the release of excess inflammatory factors from immune cells to alleviate the inflammatory storm. "In terms of mechanism research, we speak with data and find that some components in traditional Chinese medicine have played a good role, such as glycyrrhizic acid in licorice, ephedrine in ephedra, baicalin and wogonin in Scutellaria baicalensis." Zhang Weidong said. Li Yu, director of the science and Technology Department of the State Administration of traditional Chinese medicine, said that we should give full play to the advantages of the integration of clinical scientific research of traditional Chinese medicine and promote clinical and mechanism research at the same time. Obtain the clinical efficacy evidence of traditional Chinese medicine, clarify the mechanism of traditional Chinese medicine from multiple levels, and use scientific methods to clarify and explain the efficacy and mechanism of traditional Chinese medicine.
