Therapeutic Effects and Molecular Network Mechanism of Chinese herbs for Coronavirus Disease-19

Abstract Background: The coronavirus disease-19 (COVID-19) outbreak on December 2019.The present study was aimed to explore the therapeutic effects and the network pharmacology mechanism of Chinese herbs in COVID-19 patients. Methods: In this retrospective study, demographic, clinical signs, radiography, and laboratory of 78 patients were analysis from patients' medical records. Network pharmacology was applied to characterize the action mechanism of herbs decoction. Results: Of all patients were imported cases with familial aggregation. Survival analysis showed that the proportion of cough (χ2 =3.864, P=0.049) and fever (χ2 =5.549, P=0.018) in TCM group declined faster than control group. There was a significant radiographic lesions remission difference between groups (χ2 =7.666, P=0.006). After adjusted by baseline data, the changes of Lymphocytes, ALT and LDH were greater in TCM group (P=0.023, 0.005, 0.015, respectively). A total of 1852 ingredients in 13 herbs were obtained, among which, the ingredients-target network included 168 compounds and 189 targets, 38 GO terms and 63 pathways were found in enrichment analysis. Conclusion: The therapeutic effect of Chinese herbs was amelioration of cough and fever, facilitated the absorption of inflammatory infiltrates seen in the lungs, and increased the number of lymphocytes, protection of liver function via the mechanism of inhibition of coronavirus attack organs and immune cells directly. Molecular mechanisms need to be further validate in vitro and vivo.
