Objective To investigate the effects of quercetin on cell viability,apoptosis,autophagy,and phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt)/mammalian target of rapamycin(mTOR)signaling pathway in human prostate cell carcinoma PC-3 cells.Methods PC-3 cells were cultured in vitro,and cell viability was detected by CCK-8.Apoptosis was detected by TUNEL staining.Autophagy vesicle was observed by acridine orange staining.Autophagosomes was observed by GFP-LC3 plasmid transfection analysis.Expressions of autophagy-related protein microtubule associated protein 1 light chain 3 fusion protein(LC3)and Beclin-1 and PI3K/Akt/mTOR signaling pathway protein were detected by Western blot analysis.Results Quercetin inhibited cell viability in a dose-time dependent manner and induced apoptosis.Quercetin increased the number of autophagy vesicles and autophagosomes in PC-3 cells.Quercetin increased the expressions of LC3-Ⅱ/LC3-Ⅰ and Beclin-1 in PC-3 cells and decreased the expression of phosphorylated-PI3K,phosphorylated-Akt and phosphorylated-mTOR.Conclusion Quercetin may induce autophagy by inactivating PI3K/Akt/mTOR signaling pathway in PC-3 cells.
目的 探讨血管紧张素转化酶抑制剂(ACEI类药物)在心力衰竭早期的临床干预效果,为临床用药提供参考.方法 收集符合诊断标准的心力衰竭早期患者104例,随机分为两组,对照组(49例)给予积极治疗原发病、控制危险因素等治疗,治疗组(55例)在上述治疗之上加用ACEI类药物:依那普利,干预6个月.观察干预3个月前后的心功能分级、氨基末端前体BNP(NT-proBNP)、心力衰竭超声指数变化,干预6个月心力衰竭超声指数变化及药物不良反应.结果 55例治疗组患者有50例(90.91%)维持在心功能I级,49例对照组患者有30例(61.22%)维持在心功能I级(P<0.05).两组干预前的NT-proBNP水平无显著差异(P<0.05);干预3个月,治疗组NT-proBNP水平较对照组显著下降(P<0.05).使用重复测量的方差分析结果表明,干预前、干预3个月及6个月心衰超声指数水平的两组间、不同时间及组别与时间的交互作用均有统计学意义(P<0.05),治疗组干预3个月、6个月的心力衰竭超声指数水平均较治疗前降低.治疗组药物不良反应发生率为9.09%,与对照组比较差异无统计学意义(P<0.05).结论 在心力衰竭的诊治过程中,应该重视心力衰竭的早期诊断,ACEI类药物早期干预能取得较好的治疗效果.
