The coronavirus disease 2019(COVID-19) is an acute respiratory infectious disease listed as a B infectious disease, which is managed according to standards for A infectious disease. Traditional Chinese medicine and integrated traditional Chinese and Western medicine have played an active role in the prevention and control of this epidemic. China's ethnomedicine has recognized infectious diseases since ancient times, and formed a medical system including theory, therapies, formula and herbal medicines for such diseases. Since the outbreak of the COVID-19 epidemic, Tibet Autonomous Region, Qinghai Province, Inner Mongolia Autonomous Region, Xinjiang Uygur Autonomous Region and Chuxiong Autonomous Prefecture of Yunnan, Qiandongnan Autonomous Prefecture of Guizhou have issued the prevention and control programs for COVID-19 using Tibetan, Mongolian, Uygur, Yi and Miao medicines. These programs reflect the wisdom of ethnomedicine in preventing and treating diseases, which have successfully extracted prescriptions and preventive measures for the outbreak of the epidemic from their own medical theories and traditional experiences. In this paper, we summarized and explained the prescriptions and medicinal materials of ethnomedicine in these programs, and the origin of Tibetan medicine prescriptions and Mongolian medicine prescriptions in ancient books were studied. These become the common characteristics of medical prevention and treatment programs for ethnomedicine to formulate therapeutic programs under the guidance of traditional medicine theories, recommend prescriptions and prevention and treatment methods with characteristics of ethnomedicine, and focus on the conve-nience and standardization. However, strengthening the support of science and technology and the popularization to the public, and improving the participation of ethnomedicine in national public health services and the capacity-building to deal with sudden and critical diseases are key contents in the development of ethnomedicine in the future. 10.19540/j.cnki.cjcmm.20200316.408
    In vivo and in vitro antioxidant activity and α-glucosidase, α-amylase inhibitory effects of flavonoids from Cichorium glandulosum seeds. Yao Xincheng,Zhu Ling,Chen Yuxin,Tian Jun,Wang Youwei Food chemistry The aim of this study was to investigate the antioxidant, anti-glucosidase and anti-amylase activities of total flavonoids (TFs) from Cichorium glandulosum seeds, and to analyse its chemical composition by HPLC-ESI/MS. In vitro study, radical scavenging IC50 values of TFs were 7.33±0.093, 9.24±0.100, 154.33±11.38 and 256.7±4.86 μg/ml for DPPH, ABTS, hydroxyl radicals, and superoxide anion, respectively. In the 8-64 mg/ml range, α-glucosidase and α-amylase were inhibited by TFs to a certain extent. In vivo, the treatment groups with TFs (100, 200, 400 mg/kg) showed a significant decrease in the malondialdehyde level, the superoxide dismutase and glutathione levels were restored to almost normal levels, and the catalase and glutathione peroxidase levels significantly increased compared to the CCl4-intoxicated group in rats. The present study suggests that C. glandulosum seeds should be given special attention because of their antioxidant and anti-glucosidase, anti-amylase activity. 10.1016/j.foodchem.2012.12.045
