Abstract

The invention discloses an application of notoginsenoside R1 in preparation of drugs for treating small intestinal mucosal injury, intestinal inflammatory cell infiltration and increase in microvessel permeability caused by ischemia/reperfusion. The application is realized by a way that the notoginsenoside R1 inhibits I[kappa]B[alpha] degradation and metastasis of NF-[kappa]BP65 translocates to cell nuclei, and then inhibits inflammatory cytokine release; the application is realized by a way that the notoginsenoside R1 inhibits leukocytes to swim out of microvessels, so as to avoid infiltration in tissues; the application is realized by a way that the notoginsenoside R1 inhibits cell apoptosis; the application is realized by a way that the notoginsenoside R1 inhibits degradation of vascular intercellular tight-junction proteins and inhibits plasma albumin leakage; and the application is realized by a way that the notoginsenoside R1 regulates ATP5D, increases the content of ATP in intestinal canal tissues, and promotes repair of intestinal mucosa epithelial cells.

Description

Technical field [0001] The invention relates to the application of a medicine, in particular to the protective effect of notoginsenoside R1 on small intestinal ischemia-reperfusion injury. Background technique [0002] Small bowel ischemia / reperfusion (I / R) injury can occur under many conditions, such as superior mesenteric artery embolism, small bowel transplantation, cardiopulmonary bypass, abdominal aortic aneurysm surgery, trauma or hemorrhagic shock. Small bowel ischemia-reperfusion can lead to sepsis, systemic inflammatory response syndrome and multiple organ failure, with high incidence and mortality. [0003] The generation of oxygen free radicals and the initiation of the inflammatory cascade have long been considered to be the two main mechanisms that cause small bowel ischemia-reperfusion injury. Treatment targeting oxidative stress and inflammation has always been the focus of previous research. However, the results are still unsatisfactory. Because the oxidative str...
