[Intervention mechanism of psychological sub-health by Baihe Dihuang Tang based on network pharmacology].

This study was designed to screen the targets of bioactive ingredients of Baihe Dihuang Tang, and investigate the "multi-components, multi-targets and multi-pathways" intervention mechanism of Baihe Dihuang Tang on psychological sub-health. The ADME/T calculation method was used to screen the active ingredient of Baihe Dihuang Tang, and then using ADME/T calculation method to filtrate the active components of Baihe Dihuang Tang, then Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), Pharm Mapper database and Medical Subject Headings (MeSH) were combined to forecast and filtrate the targets of the main active ingredients. In addition, the predicted targets were verified by the Surflex-dock in Sybyl. The Cytoscape software was used to construct the Baihe Dihuang Tang ingredients-targets-disease network, while Clue GO software was used to analyze the molecular function and biological process of the targets. There are total 11 active ingredients and 21 targets in Baihe Dihuang Tang. A good interaction between them was supported by the score. The 21 targets were mainly involved in gamma-aminobutyric acid signaling pathway, c AMP metabolic process and monoamine transport relevant biological processes. Thus, Baihe Dihuang Tang may play a role in the intervention of psychological sub-health by regulating the activity of G-protein coupled amine receptor and the expression of monoamine neurotransmitter, which reflects the features of traditional Chinese medicine multi-components, multi-targets and multi-pathways. This research provides evidences on the pharmacological mechanism of Baihe Dihuang Tang effect on psychological sub-health.
