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 traditional Chinese medicine compound cell culture fluid and application thereof. The traditional Chinese medicine compound cell culture fluid comprises a basic culture medium, and 1 L of the basic culture medium contains 2-10 mg of notoginsenoside R1, 1-5 mg of notoginsenoside Rb1, 1-5 mg of notoginsenoside Rg1, 0.1-1 mg of notoginsenoside Rg3, 0.5-2 mg of notoginsenoside Re, 1-6 [mu] g of shikonin, 5-15 [mu] g of cordycepin and 1-20 mg of basil polysaccharide. In the traditional Chinese medicine compound cell culture fluid, notoginsenoside Rg3 can be combined with shikonin, so that the cytotoxicity can be enhanced, cord blood NK cells are promoted to be differentiated to mature functional phenotypes with high cytotoxic activity, and the killing efficiency of the NK cells on various tumor target cells is remarkably improved; the notoginsenoside Rb1 is combined with the basil polysaccharide, so that the NK cells can be driven to expand and grow, the activity of the NK cells can be maintained, and the cell purity can be improved, so that the persistence of the cell activity can be enhanced, and the tumor killing rate of the NK cells can be improved.

This invention discloses a kit for detecting SNP molecular markers related to the content of notoginsenoside R1 in Panax notoginseng, and its application in breeding for the trait of notoginsenoside R1 content in Panax notoginseng. The SNP molecular marker is SNP9-188989821, located at base position 188989821 on chromosome 5, with a mutation type of C / G. The KASP primer combination developed in this invention can accurately distinguish between Panax notoginseng with high and low notoginsenoside R1 content, and can be applied to molecular marker-assisted breeding of Panax notoginseng, shortening the breeding cycle of new varieties. Furthermore, the detection cost is low, it is not limited by the environment, and the detection results are highly accurate and easily reproducible. This has important theoretical and practical guiding significance for accelerating the genetic improvement process of breeding Panax notoginseng with high notoginsenoside R1 content and improving breeding selection efficiency.
