目的 运用中药整合药理学计算平台(TCMIP),探索巴戟天治疗抑郁症的作用机制。方法 借助TCMIP,检索巴戟天所含的化学成分信息;通过网络药理学平台,以"节点连接度"的2倍中位数为卡值,选取中药靶标-疾病基因互作网络的核心节点;在此基础上,计算"节点连接度""节点紧密度"和"节点介度"等3个拓扑结构特征值,筛选出巴戟天治疗抑郁症的核心靶标;基于基因本体数据库(GO)和KEGG通路数据库,确定药物靶标基因所编码蛋白质的分子功能、细胞内定位及其所参与的生物学反应和通路,再进一步构建"中药-成分-靶标-通路"多维关系网络。结果 测得巴戟天所含活性成分19个,主要包括蒽醌类、多糖类、环烯醚萜苷类及其他成分;筛选出巴戟天治疗抑郁症的3个核心靶标,包括5-羟色胺受体2A、2B、2C(HTR2A、HTR2B、HTR2c);结合富集计算,预测巴戟天治疗抑郁症可能与氧化磷酸化、能量代谢、钙信号通路、心肌收缩、内分泌系统、循环系统、神经系统、感觉系统、细胞通讯等通路有关。结论 借助TCMIP,发现巴戟天对抑郁症的干预作用可能与氧化磷酸化、能量代谢、钙信号通路、内分泌系统、循环系统、神经系统、感觉系统、细胞通讯等通路有关。

Objective The integrated pharmacology platform was used to explore the mechanism of morinda in the treatment of depression. Methods With TCMIP, the chemical composition information of M. officinalis was retrieved. Taking the median of 2 times of "node connectivity" as the card value, the core node of the network of Chinese medicine target-disease gene interaction was selected. On this basis, three topological feature values such as "node connectivity" "node tightness" and "node interface" were calculated to screen out core targets for treating depression by M. officinalis. Based on GO and KEGG pathway databases, molecular functions, intracellular localization of proteins encoded by drug target genes and biological responses and pathways involved are determined. The multi-dimensional relationship network of "TCM-component-target-pathway" was further constructed. Results There were 19 active compounds, including anthraquinone, polysaccharides, iridoid glycosides and other compounds.Through the network pharmacology platform, three core targets for treating depression by halberd, including 5-hydroxytryptamine receptor 2A (HTR2A), 5-hydroxytryptamine receptor 2B (HTR2B) and 5-hydroxytryptamine receptor 2c (HTR2c). Combined with enrichment calculation, it was predicted that the treatment of depression by morinda may be related through such pathways as oxidative phosphorylation, energy metabolism, calcium signaling pathway, myocardial contraction, endocrine system, circulatory system, nervous system, sensory system and cell communication.
