D-4F在七氟烷处理对急性高糖血症小鼠血管保护中的作用及机制
D-4F enhances sevoflurane-induced vascular protection during acute hyperglycemia
摘要
Abstract
AIM:To investigate the effects of sevoflurane-induced vascular protection by apolipoprotein A-1 mimetic D-4F during acute hyperglycemia.METHODS:Thrty-two male C57BL/6J mice were randomly assigned to 4 groups (n =8).Control group(CON group),D-4Fgroup,acute hyperglycemia group (AHG group),dextrose 2 g/kg (intraperitoneal injection);AHG + D-4F group.Blood glucose,isometric aortic tension,nitric oxide (NO) were measured in mice in the absence or presence of sevoflurane (1.71%).Expressions of eNOS,p-eNOS,Cav-1 in arterioles were determined by Western blot.Superoxide generation species (ROS) were assessed in human umbilical vein endothelial cells (HUVEC) cultured in 5.5 or 20.0 mmol/L glucose with isoflurane (0.5 mmol/L) in the presence or absence of brefeldin A (BFA,4 μg/mL) or D-4F (0.5 μg/mL).RESULTS:Vasodilation,phosphorylations,NO production of eNOS were decreased while Cav-1 expression was increased during acute hyperglycemia.D-4F increased endothelium-dependent vasodilation (P < 0.01) while decreased Cav-1 expression and ROS production in HG + D-4F group after sevoflurane-induction.CONCLUSION:Polipoprotein A-1 mimetic D-4F can enhance sevoflurane-induced vascular protection,decrease Cav-1 expression and ROS production while increase NO production during acute hyperglycemia.关键词
