摘要: 目的:研究解毒通络胶囊(JDTL)对糖尿病(DM)大鼠心肌结缔组织生长因子(CTGF)mRNA表达的影响及对心肌的保护作用。 方法:Wistar大鼠诱发糖尿病模型后,随机分为解毒通络胶囊治疗组、苯那普利治疗组及DM未治疗组,以10只正常大鼠作为对照。12周末检测血糖、血脂、心肌组织血管紧张素Ⅱ,应用RT-PCR检测心肌CTGF mRNA的表达水平。结果:DM未治疗组心肌组织血管紧张素Ⅱ含量、CTGF mRNA的表达明显高于对照组和治疗组(P<0.01)。结论:持续高糖能导致心肌血管紧张素Ⅱ含量增高、CTGF mRNA表达增强,而解毒通络胶囊能在一定程度上降低血管紧张素Ⅱ含量,抑制CTGF mRNA表达,从而可能减轻糖尿病性心肌病的病理变化。

Abstract: Objective To investigate the effects of JieDuTongLuo(JDTL) capsule on connective tissue growth factor(CTGF) expression in myocardial tissue in rats with diabetes mellitus(DM). Methods A total of 36 Wistar rats with DM induced by streptozotocin(STZ) were randomly divided into JDTL capsule-treated group, Benazepril-treated group, and untreated group, 10 normal rats was used as control. The levels of blood sugar, blood lipid and myocardial AngⅡ were measured by immunoradiometry and myocardial CTGF mRNA was detected by RT-PCR after 12 weeks. Results The content of myocardial Ang Ⅱ and the expression of CTGF mRNA were significantly higher in untreated group than those in control and treated groups (P<0.01). Conclusion Long lasted hyperglycemia can lead to the increase of myocardial Ang Ⅱ content and the over-expression of CTGF mRNA in myocardial tissue in diabetic rats. JDTL capsule may partly suppress it and decrease significantly the myocardial injury in diabetic rats.
