Methods: Chemical components and targets of Guiyuan Ointment were screened from the TCMSP database and BATMAN database. CFS targets were collected through GeneCards, OMIM, and DisGenet databases. The intersection of Guiyuan Ointment’s action targets and disease targets was taken. Cytoscape Version 3.9.1 was used to create a Venn diagram of drug and disease targets. The STRING database was employed to construct a protein-protein interaction (PPI) network diagram, and key targets were screened using the CytoNCA plugin in Cytoscape 3.8.2 software. The intersection targets were imported into the David database, and gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed using the microbioinformatics program. Cytoscape 3.8.2 was used to construct the Guiyuan Ointment drug-effective component-target and drug-component-target-pathway networks. Finally, molecular docking validation was conducted using AutoDock Vina software. Results: A total of 111 active components of Guiyuan Ointment were retrieved, among which quercetin, isoflavanone, poriferasta-7,22E-dien-3beta-ol, hancinol, and orchinol are key components for the prevention and treatment of CFS by Guiyuan Ointment. There are 507 CFS-related targets, with IL-6 (interleukin-6), TNF (tumor necrosis factor), STAT3 (signal transducer and activator of transcription 3), JUN, BCL2 (B-cell lymphoma/leukemia-2), HIF1A (hypoxia-inducible factor 1α subunit), AKT1 (AKT serine/threonine kinase 1), CASP3 (caspase-3), MMP9 (matrix metallopeptidase 9), and NFKB1 (nuclear factor kappa B subunit 1) being key targets for the prevention and treatment of CFS. GO enrichment analysis showed that in terms of biological processes, it may involve negative regulation of apoptosis, positive regulation of cell proliferation, positive regulation of protein phosphorylation, and positive regulation of endothelial cell proliferation, etc. The main molecular functions include enzyme binding, receptor binding, and protease binding, etc. The main cellular functions involve mitochondria, protein complexes, and cell organelles bound to the intracellular membrane, etc. KEGG enrichment analysis yielded a total of 186 signaling pathways, mainly related to the PI3K-Akt pathway, Kaposi’s sarcoma-associated herpesvirus infection, and mitogen-activated protein kinase signaling pathway, etc. The molecular docking results indicated that the core action targets and main active components in Guiyuan Ointment have stable binding activity. Conclusion: Guiyuan Ointment combines key active components such as quercetin, poriferasta-7,22E-dien-3beta-ol, orchinol, and isoflavanone with targets like IL6, TNF, STAT3, JUN, BCL2, HIF1A, AKT1, and CASP3. By regulating multiple signaling pathways such as PI3K/Akt, MAPK, and NF-κB, it modulates various biological processes in CFS patients, including immune response, cell apoptosis, and metabolic disorders. Through activating anti-apoptotic pathways, inhibiting the production of pro-inflammatory factors, and regulating energy metabolism, it verifies the multi-target and multi-pathway regulation of this formula, exerting synergistic effects on multiple targets and pathways, and significantly improving the symptoms of CFS.展开更多
