Abstract Background At present, scholars believe that severe COVID-19 is related to a variety of basic diseases, and we also observe this point using multi-omics method. The latest sequencing data of severe COVID-19 patients were combined to analyze the pathological mechanism, and pharmacological experimental research on local drugs was conducted, and a compound ingredient was found to have potential medicinal value. Results Here, we observed, for patients with severe COVID-19 disease, the differential miRNA expression is mainly low but having higher expression of mRNA. These differential mRNA expressions are associated with the activation of inflammatory pathways and ultimately with hypoxia and coagulation. Using database analysis, we found that Yi Xin Tong Mai Granule(YXTMG) might regulate COVID-19 through Toll-like receptor signaling pathway by acting on different immune targets. We found a new molecular mechanism for COVID-19 to turn the crisis around, the down-regulated miR-181a-5p mediates the up-regulation of PLAU and SERPINE1 molecules to cause cardiovascular adverse events, and YXTMG may prevent it. At the same time, molecular docking indicated that the its various components have anti-inflammatory activity. In vitro studies, we confirmed that YXTMG had antioxidant and anti-inflammatory activities. Conclusions The study has supplemented the potential mechanism for the conversion of mild to critical COVID-19 disease and screened the Chinese medicines for improving these factors, providing methodological reference for disease pathology and drug development.
