Mechanism study on preventive and curative effects of Buyang Huanwu decoction in Qi deficiency and blood stasis diseases based on network analysis

In this study, researchers adopted the network analysis method to study Buyang Huanwu decoction at three levels, namely chemical ingredients, targets and diseases, and discovered the potential effect of Buyang Huanwu decoction in cancer treatment. Besides, they analyzed the "target-target" network of Buyang Huanwu decoction based on diseases, calculated four network indexes, namely node centrality, closeness centrality, betweenness centrality and eigenvector centrality for a comprehensive evaluation on the importance and significance of each target in the network. Afterwards, key targets of Buyang Huanwu decoction were excavated to obtain two important targets--COX-2 and PPAR-gamma, which may be important targets involved in the qi deficiency and blood stasis diseases. Meanwhile, the two targets were the basis to build the core network of "chemical component-target-disease" of Buyang Huanwu decoction, which provided reference for further studies on the effect of Buyang Huanwu decoction in treating qi deficiency and blood stasis diseases. According to the study, the network analysis method was helpful to excavate potential targets Buyang Huanwu decoction in treating qi deficiency and blood stasis diseases, and could provide methodological reference for revealing the mechanism of Buyang Huanwu decoction at multiple levels, with a guiding significance for interpreting mechanisms of traditional Chinese medicinal formulae and developing new drugs.
