Abstract:[Objective]To study the mechanisms and effects of Shengqing Jiangzhuo prescription to improve the insulin sensitivity of MSG rats.[Methods]Copy the MSG obese rat models,which were randomly divided into model group,rosiglitazone group,fenofibrate group,three dose of Shengqing Jiangzhuo prescription.Then choose 8 normal rats as the normal control group.Measure the levels of glucose in skeletal muscle and the level of leptin in serum after administration for 50 days.Real-time PCR detect the expression level of PPAR,leptin,IRS1,IRS2,GLUT4 in skeletal muscle.[Results]Compared with the normal group,the model group improved the level of glucose in skeletal muscle and the level of leptin in serum significantly (P<0.01),and decreased the expression of PPAR,leptin,IRS1,IRS2,GLUT4 significantly(P<0.01,P<0.05).Compared with the model group,each of groups had some improvements of the level of glucose in skeletal muscle and the level of leptin and the level of genes expression.[Conclusion]Shengqing Jiangzhuo prescription improve the insulin sensitivity in MSG rats which by activating the genes expression of PPAR and leptin.
Key words:Shengqing Jiangzhuo prescription;MSG rats;insulin resistance

[目的]基于前期研究清热化痰方可以提高青霉素在慢性阻塞性肺疾病急性加重期(AECOPD)痰热证大鼠模型肺组织中药物浓度基础上,研究清热化痰方是否通过改善AECOPD受损肺组织的形态结构来利于抗生素在肺组织内的转运。[方法]50只Wistar雄性大鼠随机分为正常组、模型组、氨溴索组、二陈汤组、蒌芩止嗽煎组各10只。用熏吸香烟加气管内注射内毒素及鼻腔滴入金黄色葡萄球菌,鼓风干燥箱中进行风热刺激的方法建立大鼠AECOPD痰热证模型,病理组织使用苏木精-伊红(HE)染色,应用图文分析软件(IPP6.0)测量肺平均内衬间隔(MLI)、平均肺泡数(MAN)、肺泡腔面积与总面积比(PAA);同时对Weigert染色标本测量弹力纤维的相对面积。[结果]病理结果显示,AECOPD模型组与正常组比较肺组织结构严重受损,炎症细胞增多,说明模型复制成功,蒌芩止嗽煎组与氨溴索组受到破坏相对较轻,二陈汤组次之。MAN及PAA:蒌芩止嗽煎组、氨溴索组、二陈汤组与模型组相比较差异有统计学意义。Weigert染色显示,肺泡壁弹力纤维,其中以蒌芩止嗽煎组弹力纤维含量最高,以模型组受破坏最严重,其顺序从高到低依次为蒌芩止嗽煎组、氨溴索组、正常组、二陈汤组和模型组。……
