This invention belongs to the field of biomedical technology, specifically relating to a composition for treating ischemic heart disease and its application. This invention combines two or more of ginsenoside Rg1, ginsenoside Rb1, ginsenoside Re, and notoginsenoside R1, which can significantly downregulate the levels of myocardial enzymes, aspartate aminotransferase (AST), creatine kinase (CK), and lactate dehydrogenase (LDH) in myocardial coronary effusion, with an inhibitory effect significantly higher than that of a single saponin component and the positive control drug verapamil. Simultaneously, the composition exhibits better recovery capabilities for coronary flow (CF), left ventricular developmental pressure (LVDP), maximum rate of decrease in left ventricular pressure (-dp / dtmax), and heart rate (HR) in myocardial coronary effusion. Therefore, the composition can alleviate and treat myocardial ischemia-reperfusion injury through multiple targets and mechanisms, fundamentally inhibiting the development of ischemic heart disease.

The invention discloses a preparation method and application of an anti-inflammatory and vascularization-promoting sequential drug release composite fiber dressing, the dressing is loaded with functionalized core-shell structure nanoparticles NGR1-cMSN-coated CMOFs, and the nanoparticles are loaded with a vascularization-promoting drug notoginsenoside R1 by taking carboxylated mesoporous silica (cMSN) in an inner layer as a core; the metal organic framework ZIF-8 on the outer layer is used as a shell, and an anti-inflammatory drug curcumin is loaded. Through the exquisite core-shell structure design, sequential release of drugs in the wound repair process is achieved: the ZIF-8 layer firstly responds to the subacid environment of the wound to be rapidly degraded, and curcumin is released for early-stage anti-inflammation; then, the notoginsenoside R1 is slowly released by the mesoporous silicon dioxide core, and later angiogenesis is promoted. The synergistic effect mechanism of first anti-inflammation and then blood vessel promotion can effectively overcome the healing disorder of the diabetic wound and significantly accelerate the wound repair process. The dressing prepared by the invention has good biocompatibility and repairing function, and has wide application prospect in the field of chronic wound treatment.
