摘要: 目的: 探究辛伐他汀(simvastatin) 对肾血管性高血压心肌纤维化及结缔组织生长因子(CTGF) 表达的影响。方法: 建立二肾一夹肾血管性高血压(2K1C-RH) 大鼠模型, 将实验大鼠随机分为3 组:假手术组、高血压组、辛伐他汀治疗组。术后4 周末,开始以辛伐他汀(5 mg·kg-1·d-1) 灌胃, 共8 周。测量大鼠收缩压(SBP) 、心肌总胶原容积分数、心肌胶原浓度以及CTGF 的表达。结果: 与假手术组相比,高血压组的收缩压、心肌总胶原容积分数、心肌胶原浓度显著增加(P<0. 01), CTGF 表达上调(P<0. 01), 辛伐他汀抑制2K1C-RH 大鼠心肌纤维化的发展和心肌组织中CTGF 的表达(P<0. 05) 。结论: 辛伐他汀能抑制高血压心肌纤维化, 可能与下调CTGF 的表达有关。

Abstract: AIM: To investigate the effects of simvastatin on myocardial fibrosis and connective tissue growth factor (CTGF ) in renovascular hypertensive rats.METHODS: The experimental rats were randomly divided into three groups, such as sham operation group rats, hyperpiesia rats and hyperpiesia rats treated with simvastatin (5 mg㎏kg-1·d-1). Systolic blood pressure (SBP) was measured and collagen concentration (Coll) was also detected in terms of hydroxyproline concentration. VanGieson and immunohistochemistry staining combined with computed morphometry were used to evaluate the total collagen volume fraction (CVF) and CTGF expression in left ventricular tissue.RESULTS: Compared with sham operation group rats, the SBP, CVF, Coll and CTGF expression increased markedly in hyperpiesia rats (P<0. 01). Compared with the hyperpiesia rats, simvastatin inhibited myocardial fibrosis significantly and decreased CTGF expression (P<0. 05).CONCLUSION: Simvastatin can inhibit the development of myocardial fibrosis in renovascular hypertensive rats, which may be related to the decreased expression of cardiac CTGF.
