Method: Drug components and targets are screened through TCMSP and HERB databases, and disease targets are obtained with the help of GeneCards and DisGeNET databases. The “drug-active ingredients-target” network diagram is built with Cytoscape 3.9.1 software, and the genes of intersection targets are analyzed with GO and KEGG based on the DAVID database, and molecular binding energy is calculated with the help of Autodock operation. Results: 20 chemical components of Sanren decoction were screened, and 97 common targets of chemical composition targets and strients of strilearly. “Sanren decoction - chemical composition - total target - methyl flow” network diagram screen screening 5 core compounds, namely Quercetin, Kaempferol, Luteolin, Puerarin, 7-methoxy-2 methyl isoflavones. PPI network topology analysis and KEGG pathway enrichment analysis found that Sanren decoction can play a role in treating thyroid flow by acting on core targets such as signaling pathways. Molecular docking verifies the interaction between its main components and key targets, of which 10,11-Dimethoxynareline has a high docking affinity with the core targets RAF1, PRKCQ and PIK3CG. Conclusion: Network pharmacology combined with molecular docking technology reveals that Sanren Decoction can treat strients, targets and multiple pathways, providing new ideas and theoretical basis for further in-depth research and clinical application.展开更多

In many years of clinical practice, Professor Luo Yan found that people with MGD often suffer from acne, especially young people, which may be related to the secretion of large amounts of lipids from sebaceous glands, resulting in obstruction of the opening of hair follicles and meibomian glands. Professor Luo Yan believed that the pathogenesis was mainly due to the dampness and heat of the spleen and stomach accumulated in the skin and eyelids, so the treatment was used to strengthen spleen, clear heat and remove dampness, promote blood circulation and clear eyes, and Sanren Decoction was used to add and reduce prescription, which achieved remarkable results in clinical practice, as reported below.展开更多
