Serum untargeted metabolomics analysis of mice after myocardial infarction affected by qiliqiangxin capsule

Qiliqiangxin (QLQX) capsule consists of 11 herbs, namely Huang qi (astragalus membranaceus), Ren shen (ginseng), Fu zi (radix aconiti carmichaeli), Dan shen (salvia miltiorrhiza), Ting li zi (lepidium seed), Ze xie (rhizoma alismatis), Yu zhu (radix polygonati officinalis), Gui zhi (cassia twig), Hong hua (carthamus tinctorious), Xiang jia Pi (cortex periplocae), Chen Pi (pericarpium citri reticulatae), and it is a standardized commercial formula designed to address yang deficiency and to restore the balance of qi in the heart. QLQX is also known to invigorate the blood and promote the circulation of the blood and to promote the use of fluids to relieve water retention and edema, and can be used in cardiovascular diseases such as mild to moderate congestive heart failure resulting from coronary artery disease and hypertension. The further research on the effect of QLQX on cardiac function in mice after myocardial infarction was manipulated. QLQX was given to mice in myocardial infarction model by gavage with appropriate dosage and the samples were analyzed at the end of the animal experiments through the UHPLC-Q-Exactive LC-MS. The liquid mass spectrometry was used to collect and followed by further analysis of the corresponding metabolites and metabolic pathways using metabolomics analysis. As a result, 9 differential metabolites were identified, with 15 being up-regulated and 4 down-regulated following intervention with QLQX. Then the metabolic pathways by KEGG enrichment pathway bubble diagram was analyzed, and 4 metabolic pathways were obtained, and combined with the metabolites that had been screened and analyzed together, finally the two differential metabolites, 2,5-Dihydroxybenzenesulfonic Acid and o-Cresol sulfate were found. The Glycerophospholipid metabolism pathway was closely related to the remaining seven differential metabolites, and the pathway might be an important pathway related to the effects of QLQX on cardiac function in mice.
