ObjectiveTo explore the mechanism of Herllamo Bathart Essential Oil Shower Gel for the external treatment of psoriasis by employing the network pharmacology method.MethodsThe main component of Herllamo Bathart Essential Oil Shower Gel was Gleditsia sinensis, and the active chemical components and its corresponding effect targets of Gleditsia sinensis were screened by using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform. Targets related to psoriasis were retrieved by employing the GeneCards and OMIM databases. The Venny 2.1.0 platform was used to obtain intersection targets between active chemical components of Gleditsia sinensis and targets related to psoriasis. For targets related to Gleditsia sinensis for treating psoriasis, the Cytoscape 3.8.2 software was used to establish network diagram of active chemical components of Gleditsia sinensis-disease targets of psoriasis, and protein-protein interaction (PPI) network was established by the STRING database, as well as the Gene Ontology (GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed. ResultsA total of 5 active chemical components from Gleditsia sinensis, including stigmasterol, sitosterol, stigmast-4-ene-3,6-dione, epicatechin, and eicosanoid-11-enoic acid, were obtained, and there were 162 corresponding effect targets in total. There were 4104 targets related to psoriasis in total, and 106 intersection targets were obtained after acquiring intersection between active chemical components of Gleditsia sinensis and targets related to psoriasis. The network diagram of active chemical components of Gleditsia sinensis-disease targets of psoriasis revealed that epicatechin had the highest degree value, and it played the most important role in the treatment of psoriasis with Gleditsia sinensis. The results of PPI network topology analysis indicated that the key targets of Gleditsia sinensis for the external treatment of psoriasis were VEGFA, AKT1, TNF, IL-6, MMP9, PTGS2, IL-1β, JUN, EGF, and Caspase-3. The results of enrichment analysis indicated that Gleditsia sinensis for the treatment of psoriasis involved biological processes in terms of response to inorganic substances, response to hormones, negative regulation of cell mass proliferation, positive regulation of cell migration, etc.,involved cellular compositions with respect to membrane raft, membrane microdomain, transcriptional regulatory complex, and cystic cavity, etc.,and involved molecular functions of DNA binding and transcription factor binding, transcription factor binding, RNA polymerase II specific DNA binding and transcription factor binding, protein homologous dimerization activity, etc., as well as involved signaling pathways in terms of TNF signaling pathway, IL-17 signaling pathway, etc. ConclusionThe main component of Gleditsia sinensis from Herllamo Bathart Essential Oil Shower Gel may act on VEGFA, AKT1, TNF, IL-6, MMP9, and other relevant targets, affect IL-17, TNF, and other signaling pathways, so as to achieve the purpose of treatment of psoriasis by active chemical components in terms of epicatechin, stigmasterol, stigmast-4-ene-3,6-dione, eicosanoid-11-enoic acid, and sitosterol, etc.
