Myocardial ischemia (MI), a condition in which the heart is unable to function due to insufficient blood and oxygen supply, is a major cause of death from coronary heart disease (CHD). Yiqi Tongluo capsule (YTC) is a Chinese patent drug which commonly used for treatment of MI in clinic. However, the related active components of YTC for treatment of MI were still uncovered. This paper is aimed to study the quality markers (Q-markers) of YTC and further optimize the extraction process of YTC based on Q-markers, providing research foundation for the further modern pharmaceutical preparations of YTC. We firstly used UPLC-QTOF-MS to analyze the constituents of YTC absorbed in blood, then isoprenaline (ISO) induced H9c2 cell model was used further screen the active constituents with protective effects on cardiomyocytes. After that, the orthogonal table (L9 (3⁴)) was used to optimize the extraction process with three levels of 4 factors (water addition, immersion time, extraction time and decoction times). Finally, the HPLC fingerprint of 15 batches of optimized YTC was established. In our present study, a total of 33 components were identified in YTC, of which 10 components were absorbed in blood. Among the 10 components, 8 compounds had significant protective effects on ISO stimulated H9c2 cells, including Paeoniflorin, Ferulic acid, Calycosin, Senkyunolide A, N-butylphthalide, Z-ligustilide, LevistilideA, and Astragaloside IV, which were considered as the Q-markers of YTC. The optimized extraction process based on Q-marker as follows: soaking 1 h, then adding 8 times water to extract 3 times by decoction, each extraction lasts 1.5 h. The HPLC fingerprint of optimized YTC was established with 15 batches of YTC samples, and the optimized YTC samples has no significant toxicity to the heart, liver, spleen, lungs, and brain tissues of rats.

BACKGROUNDIschemic stroke is caused by local lesions of the central nervous system and is a severe cerebrovascular disease. A traditional Chinese medicine, Yiqi Tongluo Granule (YQTL), shows valuable therapeutic effects. However, the substances and mechanisms remain unclear.PURPOSEWe combined network pharmacology, multi-omics, and molecular biology to elucidate the mechanisms by which YQTL protects against CIRI.STUDY DESIGNWe innovatively created a combined strategy of network pharmacology, transcriptomics, proteomics and molecular biology to study the active ingredients and mechanisms of YQTL. We performed a network pharmacology study of active ingredients absorbed by the brain to explore the targets, biological processes and pathways of YQTL against CIRI. We also conducted further mechanistic analyses at the gene and protein levels using transcriptomics, proteomics, and molecular biology techniques.RESULTSYQTL significantly decreased the infarction volume percentage and improved the neurological function of mice with CIRI, inhibited hippocampal neuronal death, and suppressed apoptosis. Fifteen active ingredients of YQTL were detected in the brains of rats. Network pharmacology combined with multi-omics revealed that the 15 ingredients regulated 19 pathways via 82 targets. Further analysis suggested that YQTL protected against CIRI via the PI3K-Akt signaling pathway, MAPK signaling pathway, and cAMP signaling pathway.CONCLUSIONWe confirmed that YQTL protected against CIRI by inhibiting nerve cell apoptosis enhanced by the PI3K-Akt signaling pathway.

Doxorubicin (DOX) is a broad-spectrum chemotherapeutic drug used in clinical treatment of malignant tumors. It has a high anticancer activity but also high cardiotoxicity. The aim of this study was to explore the mechanism of Tongmai Yangxin pills (TMYXPs) in ameliorating DOX-induced cardiotoxicity through integrated metabolomics and network pharmacology. In this study, first, an ultrahigh-performance liquid chromatography-quadrupole-time-of-flight/mass spectrometry (UPLC-Q-TOF/MS) metabonomics strategy was established to obtain metabolite information and potential biomarkers were determined after data processing. Second, network pharmacological analysis was used to evaluate the active components, drug-disease targets, and key pathways of TMYXPs to alleviate DOX-induced cardiotoxicity. Targets from the network pharmacology analysis and metabolites from plasma metabolomics were jointly analyzed to select crucial metabolic pathways. Finally, the related proteins were verified by integrating the above results and the possible mechanism of TMYXPs to alleviate DOX-induced cardiotoxicity was studied. After metabolomics data processing, 17 different metabolites were screened, and it was found that TMYXPs played a role in myocardial protection mainly by affecting the tricarboxylic acid (TCA) cycle of myocardial cells. A total of 71 targets and 20 related pathways were screened out with network pharmacological analysis. Based on the combined analysis of 71 targets and different metabolites, TMYXPs probably played a role in myocardial protection through regulating upstream proteins of the insulin signaling pathway, MAPK signaling pathway, and p53 signaling pathway, as well as the regulation of metabolites related to energy metabolism. They then further affected the downstream Bax/Bcl-2-Cyt c-caspase-9 axis, inhibiting the myocardial cell apoptosis signaling pathway. The results of this study may contribute to the clinical application of TMYXPs in DOX-induced cardiotoxicity.
