Erythropoietin inhibits angiotensin Ⅱ induced cardiomyocyte hypertrophy in vitro via activating PI3K/Akt-eNOS pathway

Objective To explore the effect of erythropoietin (EPO) on angiotensin Ⅱ (Ang Ⅱ) induced neonatal rat cardiomyocyte hypertrophy and the association with PI3K/Akt-eNOS signaling pathway. Methods Cardiomyocytes were isolated from new-born Sprague-Dawley rats and stimulated by Ang Ⅱ in vitro. The cell surface area and mRNA expression of atrial natriuretic factor (ANF) of cardiomyocytes were determined in the presence and absence of various concentrations of EPO, phosphatidylinositol 3'-kinase (PI3K) inhibitor LY294002 and nitric oxide synthase (NOS) inhibitor L-NAME. Intracellular signal molecules, such as Akt, phosphorylated Akt, eNOS and phosphorylated eNOS protein expressions were detected by western blot. Nitric oxide (NO) level in the supernatant of cultured cardiomyocytes was assayed by NO assay kit. Results EPO (20 U/ml) significantly inhibited Ang Ⅱ induced cardiomyocyte hypertrophy as shown by decreased cell surface area and ANF mRNA expression (all P ＜0.05). EPO also activated Akt and enhanced the expression of eNOS and its phosphorylation (all P ＜ 0.05), increased the NO production (P ＜0.01). These effects could be partially abolished by cotreatment with LY294002 or L-NAME (all P ＜ 0.05). Conclusion EPO attenuates Ang Ⅱ induced cardiomyocytes hypertrophy via activating PI3K-Akt-eNOS pathway and promoting NO production.

西洛他唑抗动脉粥样硬化的作用机制

目的观察西洛他唑对兔动脉粥样硬化斑块组织的影响,进一步探讨西洛他唑抗动脉粥样硬化作用及其可能机制。方法将30只新西兰雄性白兔随机分为正常对照组、高脂饮食组和西洛他唑组。酶法检测血脂,免疫沉淀法测定血清C反应蛋白水平,免疫组织化学检测基质金属蛋白酶9和核因子κB的表达,病理形态学分析各组主动脉内膜厚度和斑块面积,逆转录聚合酶链反应检测血管组织单核细胞趋化蛋白1mRNA的表达。结果实验第12周末,西洛他唑组总胆固醇、甘油三酯和低密度脂蛋白胆固醇水平低于高脂饮食组,但高于正常对照组(P均<0.01);西洛他唑组主动脉内膜厚度和斑块面积低于高脂饮食组,但大于正常对照组(P均<0.01);西洛他唑组核因子κB、单核细胞趋化蛋白1和基质金属蛋白酶9的表达弱于高脂饮食组,但强于正常对照组(P均<0.01)。结论西洛他唑有抗动脉粥样硬化作用,其作用机制可能与下调核因子κB、单核细胞趋化蛋白1及基质金属蛋白酶9的表达有关。     

LC术前行MRCP检查指征的探讨

目的：探讨LC术前行MRCP检查的指征。方法回顾分析1300例LC术前行MRCP检查的临床资料,其中：单纯胆囊组300例,高危因素胆囊组1000例,与同期1300例LC术前仅行B超检查的临床资料进行对照分析。结果对于高危因素胆囊患者, MRCP组在LC术前发现胆道变异、减少术中胆道损伤及术后胆道残余结石发生率,降低中转开腹率,明显优于B超组,两组间有统计学差异;对于单纯胆囊MRCP组与B超无统计学差异。结论高危因素胆囊患者,是LC术前行MRCP检查的指征。
