Analysis of Traditional Chinese Medicine Syndromes of 46 Cases of COVID-19 / 中国实验方剂学杂志

ABSTRACT

Objective:To analyze the traditional Chinese medicine（TCM） syndromes of 46 patients with coronavirus disease-2019 (COVID-19) by cluster analysis method. Method:The 46 COVID-19 patients with TCM symptoms, signs, tongue and pulse were analyzed by frequency analysis and clustering analysis, and the TCM syndrome types of COVID-19 patients were classified and summarized by combining clinical expertise, and the evolution law was analyzed by combining the median days of the syndrome collection. Result:The major signs and symptoms of the 46 patients with COVID-19: fever (frequency of 39, accounted for 84.8%), poor appetite (frequency of 44, 95.7%), fatigue (frequency of 42, 91.3%), wheezing breath (frequency of 35, 76.1%), dry mouth (frequency of 21, 45.7%), lung condition short (frequency of 20, 43.5%), defecate pond (frequency of 15, 32.6%), red tongue (frequency 30, accounting for 65.2%), yellowish moss (frequency 27, accounting for 58.7%), and slimy pulse (frequency 30, accounting for 62.5%). TCM syndromes were divided into seven types, i.e. dampness and heat syndrome (13 cases), dampness and toxin syndrome (10 cases), heat stasis syndrome (7 cases), dampness and heat syndrome (5 cases), cold dampness internal invasion syndrome (4 cases), dampness poison blood stasis syndrome (2 cases).According to the time of onset, there were cold and dampness syndrome (median days 6.5 days), dampness was heavier than heat syndrome (10 days), dampness and heat syndrome (10 days), dampness and heat syndrome (11.5 days), heat stagnation of liver and gallbladder syndrome (13 days), dampness and blood stasis syndrome (15 days), and Yin injury syndrome (16 days). Conclusion:Among the 46 cases of COVID -19, damp-heat syndrome was the most common, followed by heat stagnation of liver and gallbladder syndrome, Yin injury and gas consumption syndrome, cold and damp internal invasion syndrome, and dampness and blood stasis syndrome. The pathogenesis of the disease evolved into heat and poison, and later appeared to consume Qi Yin performance.
