Discussion on the relationship between irritable bowel syndrome and premature ejaculation from 5-HT and prediction of natural drugs / 国际中医中药杂志

ABSTRACT

Objective:To explore the relationship between irritable bowel syndrome (IBS) and premature ejaculation (PE) from 5-HT; To predict the natural drugs with therapeutic effect.Methods:Targets related to IBS and PE were screened in the GeneCards, DisGeNET, TTD, OMIM, DrugBank databases. After removing duplicates, the two disease targets were intersected and imported into STRING platform, and the protein interaction network between IBS and PE targets related to 5-HT receptor was obtained. GO enrichment analysis was carried out on the intersected targets by R language, and Coremine Medical platform was used for predicting natural drugs.Results:5-HT1A, 5-HT1B, 5-HT2A, 5-HT2C and 5-HT3A were the common targets related to 5-HT in IBS and PE. GO function enrichment yielded 250 gene function related information, mainly enriched in serotonin receptor signaling pathways, cell response to dopamine, and response to dopamine. The prediction of natural drugs obtained 14 kinds of Chinese materia medica, including Nelumbinis Semen, Nelumbinis Rhizomatis Nodus, Nelumbinis Receptaculum, Nelumbinis Stamen, Nelumbinis Folium, Nelumbinis Plumula, Ginkgo Semen, and Ginkgo Folium.Conclusions:Abnormal 5-HT levels can affect gastrointestinal motility, ejaculation latency, and glans sensitivity. Elevated central 5-HT levels are a common pathogenesis of IBS and PE. The interaction between receptors such as 5-HT1A and 5-HT3A and 5-HT can regulate gastrointestinal motility and secretion activities, intestinal nervous system, and reduce intestinal hypersensitivity; increasing the sensitivity of the 5-HT1A receptor can reduce the ejaculation threshold and promote ejaculation, while increasing the sensitivity of the 5-HT2C receptor can increase the ejaculation threshold.
