摘要: 目的 探讨麝香保心丸对心力衰竭大鼠肾脏血管紧张素Ⅱ受体(angiotensin Ⅱ receptor, ATR)各亚型表达水平的影响。方法 选择雄性Wistar大鼠80只,采用抽签法随机分为正常对照组(A组,10只)、假手术组(B组,10只),其余60只制作心肌梗死后心力衰竭模型,35只大鼠模型制作成功,并采用抽签法随机分为模型组(C组,9只)、阳性药物对照组(D组,8只)、麝香保心丸小剂量组(E组,9只)和麝香保心丸大剂量组(F组,9只)。取大鼠肾脏皮质,采用反转录聚合酶链反应(RT-PCR)法分别测定各组大鼠ATR各亚型mRNA表达水平。结果 B组与A组AT1R、AT2R比较,差异无统计学意义(P>0.05);与B组比较,C组大鼠AT1R表达明显上调,AT2R表达明显下调,差异均有统计学意义(P<0.05);与C组比较,D、E、F组大鼠AT1R表达明显下调,AT2R表达明显上调,差异有统计学意义(P<0.01);与E组比较,F组大鼠AT1R表达下调更显著(P<0.05)。结论 采用麝香保心丸治疗,可调节大鼠肾脏ATR各亚型的表达,使心力衰竭时上调的AT1R表达下调,下调的AT2R表达上调,对保护肾脏功能、改善心力衰竭起到了有益作用。同时,与小剂量麝香保心丸相比,大剂量麝香保心丸的疗效更为显著。

Abstract: Objective To explore the effect of Shexiangbaoxin pills (SXBXP) on expression of renal angiotensin Ⅱ receptor(ATR) subtypes in rats with heart failure.Methods Eighty male Wistar rats were randomly divided into control group (group A, n=10) and sham operation group (group B, n=10). The heart failure model was established successfully in 35 of the rest 60 male Wistar rats. The 35 heart failure model rats were randomly divided into four group: heart failure model group (group C, n=9), medicine control group (group D, n=8), small dose of SXBXP group (group E, n=9) and large dose of SXBXP group (group F, n=9). The mRNA levels of ATR subtypes of renal cortex were measured by reverse transcription polymerase chain reaction (RT-PCR) in each group. Results Compared with group A, expression of AT1R and AT1R showed no significant difference in group B(P>0.05), compared with group B, expression of AT1R was increased significantly in group C(P<0.05), expression of AT1R was decreased significantly in group C(P<0.01). Compared with group C, expression of AT1R was decreased significantly in group D, E and F(P<0.05), expression of AT1R was increased significantly in group D, E and F(P<0.01). Compared with group E, expression of AT1R was decreased significantly in group F(P<0.05). Conclusion SXBXP regulated the expression of renal ATR subtypes, including the downregulation of AT1R and the upregulation of AT1R in rats with heart failure, and it is also effective to protect renal function and improve heart failure, especially large dose of SXBXP.
