| 摘 要： | 目的 研究三七总皂苷(PNS)对非酒精性脂肪性肝病(NAFLD)小鼠肝脏脂质沉积及一氧化氮(NO)-诱导型一氧化氮合酶(iNOS)-核因子κB(NF-κB)信号通路的影响。方法 随机将40只雄性BALB/c小鼠分为对照组、模型组、三七总皂苷(PNS)干预组和辛伐他汀干预组,每组10只。采用高脂饲料持续喂养法建立NAFLD小鼠模型,然后分别给予生理盐水或PNS或辛伐他汀灌胃干预12 w。使用全自动生化仪检测血清总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白(HDL-C)、低密度脂蛋白(LDL-C)、丙氨酸氨基转移(ALT)和天冬氨酸氨基转移酶(AST),采用Western Blot法检测肝组织NO-iNOS-NF-κB通路蛋白表达。结果 PNS干预组动物体质量、肝质量和内脏脂肪比分别为(31.6±1.7)g、(6.3±0.9)g和(3.4±0.5)%,显著低于模型组【分别为(36.5±2.0)g、(8.1±1.2)g和(4.3±0.8)%,P<0.05】;血清TC、TG和LDL-C水平分别为(2.5±0.8)mmol/L、(0.9±0.3)mmol/L和(1.1±0.3)mmol/L,显著低于模型组【分别为(4.5±1.6)mmol/L、(2.7±1.1)mmol/L和(2.3±0.6)mmol/L,P<0.05】,而血清HDL-C水平为(0.4±0.2)mmol/L,显著高于模型组【(0.2±0.1)mmol/L,P<0.05】;血清ALT和AST水平分别为(32.5±6.8)U/L和(41.3±6.8)U/L,显著低于模型组【分别为(65.2±8.7)U/L和(62.7±6.9)U/L,P<0.05】;PNS干预组肝组织NO、iNOS和p-NF-κB蛋白表达相对水平分别为(1.2±0.2)、(1.1±0.1)和(1.2±0.2),显著低于模型组【分别为(5.3±0.6)、(4.8±0.5)和(5.6±0.5),P<0.05】。结论 三七总皂苷可能通过抑制NO/iNOS/NF-κB通路蛋白表达从而有效降低NAFLD小鼠血脂水平,改善肝组织脂质沉积。

| Abstract: | Objective The aim of this experiment was to explore the effect of panax notoginsenosides(PNS)on liver steatosis and nitric oxide(NO)-induced nitrogen monoxide synthase(iNOS)-nuclear factor kappa-B(NF-κB)pathway protein expression in mice with high-fat-induced non-alcoholic fatty liver diseases(NAFLD).Methods 40 male BALB/c mice were randomly divided into normal,model,PNS-intervened and simvastatin-intervened group,with 10 mice in each group.The NAFLD model in mice was established by feeding high fat diet for 12 weeks.After the successful model completion,the mice were feed with normal saline,PNS solution or simvastatin solution for 12 weeks.Serum total cholesterol(TC),triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C),alanine aminotransferase(ALT)and aspartate aminotransferase(AST)levels were detected.The protein expressions of NO-iNOS-NF-κB pathway in liver tissues were detected by Western bloting.Results The body mass,liver mass and visceral fat ratio in PNS-intervened group were(31.6±1.7)g,(6.3±0.9)g and(3.4±0.5)%,significantly lower than(36.5±2.0)g,(8.1±1.2)g and(4.3±0.8)%,P<0.05]in the model group;serum TC,TG and LDL-C levels were(2.5±0.8)mmol/L,(0.9±0.3)mmol/L and(1.1±0.3)mmol/L,significantly lower than(4.5±1.6)mmol/L,(2.7±1.1)mmol/L and(2.3±0.6)mmol/L,respectively,P<0.05],while serum HDL-C level was(0.4±0.2)mmol/L,significantly higher than(0.2±0.1)mmol/L in the model group(P<0.05);serum ALT and AST levels were(32.5±6.8)U/L and(41.3±6.8)U/L,significantly lower than(65.2±8.7)U/L and(62.7±6.9)U/L,respectively,P<0.05]in the model group;the relative protein expressions of NO,iNOS and p-NF-κB were(1.2±0.2),(1.1±0.1)and(1.2±0.2),significantly lower than(5.3±0.6),(4.8±0.5)and(5.6±0.5),respectively,P<0.05]in the model group.Conclusion PNS could effectively reduce blood lipids levels and alleviate liver steatosis in mice with NAFLD,which might be related to the inhibition NO/iNOS/NF-κB pathway protein expression. |
