Firstly, we used a network proximity approach to calculate and compare the effectiveness of the formula with that of Western drugs for each type of angina, including all targets and intersecting targets, from a topological perspective. Secondly, we compared the mechanisms of action of the two angina pectoris at three levels and five aspects, including conventional and modular analysis approaches. Thirdly, based on the unique functions of each angina in the complex heterogeneous network, we designed a reverse process for finding the material basis using dynamic, static, and enriched items as well as a total item. Finally, the designed inverse process, material basis, and mechanism of action were validated.
The target network of Xuefu Zhuyu decoction is closer to the target network of each type of angina than that of Western drugs, and the intersection targets have a closer proximity. Comparison of the mechanisms of action showed that stable angina and unstable angina had 158 common targets, while the unique targets were 34 and 1, respectively. Modularity analysis showed that the GO similarity of target modules was highly correlated with KEGG similarity. We ended up with 67 compounds upregulated for stable angina and 47 compounds upregulated for unstable angina. Our results were validated by literature mining, high-volume molecular docking, and miRNA enrichment analysis.
For both types of angina pectoris, Xuefu Zhuyu decoction is superior to Western drugs. A comparison of various aspects led to the unique mechanisms of action, from which the material basis of each type of angina was deduced.
首先，我们采用网络接近度方法，从拓扑学角度计算并比较该方剂与西药针对每种类型心绞痛（包括所有靶点和交集靶点）的有效性。其次，我们从三个层次和五个方面比较了两种心绞痛的作用机制，包括常规和模块化分析方法。第三，基于每种心绞痛在复杂异质网络中的独特功能，我们设计了一个反向过程，以动态、静态、富集项以及总项为基础来寻找物质基础。最后，对设计的反向过程、物质基础和作用机制进行了验证。
血府逐瘀汤的靶点网络比西药的靶点网络更接近每种类型心绞痛的靶点网络，且交集靶点的接近度更高。作用机制比较显示，稳定型心绞痛和不稳定型心绞痛有158个共同靶点，而独特靶点分别为34个和1个。模块化分析表明，靶点模块的GO相似性与KEGG相似性高度相关。我们最终得到了67种稳定型心绞痛上调的化合物和47种不稳定型心绞痛上调的化合物。我们的结果通过文献挖掘、大量分子对接和miRNA富集分析得到了验证。
对于两种类型的心绞痛，血府逐瘀汤均优于西药。多方面比较得出了独特的作用机制，由此推导出每种类型心绞痛的物质基础。
