【摘要】 目的：研究参芪复方改善2型糖尿病大血管病变炎症反应与胰岛素抵抗的作用机理,为以益气养阴、活血化瘀为治疗原则的参芪复方在临床的广泛应用提供理论依据。方法：GK大鼠饮水中加入N-硝基-L-精氨酸甲酯(L-NAME),同时给高脂饮食35d造模。实验按GK大鼠随机血糖分为GK组18只、模型组(为阳性对照)19只、西药阿托伐他汀组(简称为西药组)18只、中药参芪复方组(简称为中药组)18只,SPF级Wistar大鼠18只作为正常Wistar对照组(简称为Wistar组),共5组。造模同时开始给药,连续35天。观察一般状况、摄食量、饮水量及体重变化。实验结束时葡萄糖氧化酶法测定空腹血糖(FPG)；酶法测定血清总胆固醇、甘油三酯(TC、TG); ELISA法测定血清C-反应蛋白(CRP)；放射免疫法测血清胰岛素(INS)含量,计算胰岛素抵抗指数(IRI)、胰岛素敏感性指数(IAI)；用Real-TimePCR测定胸主动脉ICAM-1mRNA的表达,并观察光镜下的病理形态变化。结果：中药组动物在实验结束后FPG、TC、TG、CRP、INS的含量均较模型组有显著下降(p<0.01或p<0.05),IRI较模型组显著降低(p<0.01),IAI较模型组显著升高(p<0.01)。ICAM-1mRNA的表达也较模型组明显降低(p<0.01)。中药组动物腹主动脉内膜病变数目及程度均有明显减少(p<0.05)。结论：参芪复方具有改善T2DM大血管病变炎症反应与胰岛素抵抗的作用。其作用可能是通过以下机制完成：①降低FPG和血清TC、TG含量；②降低血清CRP含量；③抑制主动脉ICAM-1mRNA的表达；④减轻胰岛素抵抗,升高胰岛素敏感性。更多还原

【Abstract】 Objective To research the mechanisms of ShenQi compound recipe(SQCR)treating type 2 diabetes mellitus (T2DM) on macrovascular complications of the Inflammatory response and insulin resistance. To provid the theory bases of representing with SQCR applying Traditional Chinese Medicine in clinic.Methods Copied T2DM model with macrovascular complications by adding Nω-nitio-L-arginine methyl ester (L-NAME) in drinking water and giving high fat diet 35 days. Divided animals into five groups according to the level of blood sugar: Goto-Kakizaki(GK), model, Atorvastatin(westernmedicine), ShenQi compound recipe(Traditional Chinese Medicine)and normal control and administrated when Copying T2DM model with macrovascular complications except normal control group. During the experiment period, observed general status and measured the values of drinking, eating, body weight. At the end, estimated Fasting blood glucose(FPG)、total cholesterol(TC)、Triglyceride(TG) with serologic enzyme method; C-reactive protein(CRP) with enzyme-linked immunosorbent assay (ELISA); insulin (INS) with radio immunoassay, count IRI、IAI; abdominal aorta intercellular adhesion molecule-1 (ICAM-1)mRNA with real time RT-PCR; abdominal aorta pathologic with light microscope.Results FPG、IRI,content of TC、TG、CRP、INS were all decreased in SQCR group compared with model group (p<0.01 or p<0.05). IAI was increased in SQCR group compared with model group (p<0.01). The expression of abdominal aorta ICAM-1mRNA in SQCR group was also decreased remarkable compared with model group (p<0.01). SQCR could decrease the amount and the degree of infiltrated in abdominal aorta.Conclusions SQCR has remarkable effect on macrovascular complications and Improve vascular endothelial function. The mechanisms of it may realize as follows:①Decreased FPG and the content of TC、TG;②Decreased the content of CRP;③Inhibited the expression of abdominal aorta ICAM-1mRNA;④Reduced insulin resistance and increased insulin sensitivity.更多还原
