心肌梗死(MI)是一种常见的心血管疾病,其定义为由斑块破裂、血栓形成、管腔狭窄或冠状动脉阻塞引起的心肌缺血和缺氧损伤。然而,急诊经皮冠状动脉介入治疗的发展使缺血心肌的血液灌注得以迅速恢复,挽救了垂死的心肌细胞。近年来,一些心肌细胞的死亡会造成不可逆的损伤,影响心功能的恢复。淫羊藿苷作为一种天然化学提取物,已被用于治疗各种疾病。在这项研究中,我们采用了各种方法来观察MI,包括蛋白质印迹,定量RT-PCR,免疫组化和流式细胞仪分析,淫羊藿苷。研究结果表明,淫羊藿苷可以阻止MI诱导的细胞凋亡。这是通过Nrf 2/HO-1信号通路抑制促炎因子来实现的。这些数据表明,淫羊藿苷可能是一种有效的治疗心肌梗死。
Myocardial infarction (MI) is a prevalent cardiovascular disease defined by myocardial ischemia and hypoxic damage caused by plaque rupture, thrombosis, lumen stenosis, or blockage in the coronary artery. However, the development of emergency percutaneous coronary interventional therapy has enabled the rapid restoration of blood perfusion to ischemic myocardium and the rescue of dying myocardium cells. Some dying myocardium cells have caused irreversible damage and impaired cardiac function recovery in recent years. Icariin has been utilized to treat various ailments as a natural chemical extract. In this study, we employed a variety of approaches to observe MI, including western blotting, quantitative RT–PCR, immunohistochemistry, and flow cytometric analysis using icariin. As demonstrated by the research findings, icariin may prevent MI-induced cell apoptosis. This is accomplished by inhibiting proinflammatory factors via the Nrf2/HO-1 signaling pathways. These data imply that icariin may be an effective treatment for MI.
