Aim To investigate the protective effect and the underline mechanisms of total flavonoids from Sorbus Tianschanica L leaf (TFST) against myocardial ischemia/reperfusion (I/R) injury.Methods The I/R injury model of rat isolated heart was prepared by improved Langendorff retrograde perfusion method.Following the treatment,the coronary blood flow levels (CF),left ventricular developed pressure (LVDP) and maximal rise/fall rate of left ventricular pressure (±dp/dt_(max)) were monitored as the myocardial function.The superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in myocardial tissue were measured by the commercial kits. The in vitro anti-oxidative capacity of TFST was detected by the DPPH and lipid peroxidation reaction system.Results Compared with I/R injury group, pre-incubation with TFST (6.0 mg·L~(-1)) significantly improved the LVDP,±dp/dt_(max) and CF during reperfusion. TFST (6.0 mg·L~(-1)) treatment significantly increased the SOD activities and reduced the MDA levels in myocardium tissue.Moreover,TFST (from 6.25 to 100.0 mg·L~(-1)) scavenged the DPPH, hydroxyl radical and superoxide anion free radicals, and inhibited the lipid peroxidation reaction in a concentration-dependent way.Conclusions All the results demonstrate that TFST possesses the cardioprotective effect on ischemia/reperfusion injury.This efficacy may be due to its antioxidative activity.
3.Role of genes in the pathogenesis of keratoconus
International Eye Science 2024;24(10):1588-1594
Keratoconus(KC)is a disease characterized by limited corneal cone-like protrusions accompanied by thinning of the corneal stroma in the area of protrusion, which commonly occurs before and after puberty, manifests itself bilaterally, and is a potentially blinding ophthalmic disease. It is a potentially blinding eye disease. Studies have shown that its pathogenesis is related to environmental factors, inflammatory response, immune function, and mechanical stimulation, but the mechanism of the occurrence and progression of KC has not yet been conclusively determined. A variety of genes, represented by corneal remodeling-related genes, have been found to have some influence on the development of cone cornea. More studies are still digging into the genetic targets associated with the development of cone cornea. This article reviews the targets and influence of genes in the pathogenesis of cone cornea, to explore the application value of genes in the early diagnosis and intervention of cone cornea, and to provide new ideas for future research on the pathogenesis of cone cornea.
