摘 要:目的:探讨丹皮酚与三七总皂苷配伍应用对血管紧张素Ⅱ(angiotensinⅡ,AngⅡ)诱导增殖的心脏成纤维细胞胶原合成的调节作用。方法:选取原代培养的乳鼠心脏成纤维细胞,随机分为6组,分别为空白组,模型组,丹皮酚(45 mg·L^(-1))组,三七总皂苷(50 mg·L^(-1))组,丹皮酚与三七总皂苷配伍的高、低剂量(丹皮酚45,30 mg·L^(-1)+三七总皂苷50,30 mg·L^(-1))组。药物干预48 h,采用逆转录-聚合酶链式反应(RT-PCR)法检测Ⅰ型胶原,Ⅲ型胶原的mRNA表达水平,蛋白质免疫印迹(Western blot)法检测各组细胞的Ⅰ型胶原和Ⅲ型胶原的蛋白表达水平。结果:与空白组比较,模型组Ⅰ型胶原和Ⅲ型胶原的mRNA及蛋白表达明显升高(P<0.01);与模型组比较,AngⅡ可刺激心脏成纤维细胞(cardiac fibroblasts,CFs)的增殖,丹皮酚,三七总皂苷及其配伍的高、低剂量均可抑制Ⅰ型胶原和Ⅲ型胶原的mRNA及蛋白表达(P<0.05),其中配伍组的抑制作用较优,且配伍高剂量作用时抑制效果更佳。结论:丹皮酚和三七总皂苷配伍组方可抑制血管紧张素Ⅱ诱导增殖的心脏成纤维细胞Ⅰ型胶原和Ⅲ型胶原蛋白的基因表达,显示明显的协同效应。Objective: To investigate the effect of combination of paeonol( Pae) and Notoginseng Radix et Rhizoma saponins( NRS) on expressions of type Ⅰ and Ⅲ collagen in proliferation of cardiac fibroblasts induced by angiotensin Ⅱ( AngⅡ). Method: Primary cultured cardiac fibroblasts( CFs) of neonatal rats were randomly divided into six groups: blank group, model group, Pae group( 45 mg ·L-1),NRS group( 50 mg·L-1),combined Pae and NRS high-dose and low-dose groups( Pae 45,30 mg·L-1+ NRS 50,30 mg·L-1). The mRNA expressions of type Ⅰ and Ⅲ collagen were detected by RT-PCR after drug intervention for 48 h. The protein expressions of type Ⅰ and Ⅲ collagen were determined by Western blot. Result: As compared with the blank group,the mRNA expressions and protein expressions of type Ⅰ and Ⅲ collagen were significantly increased in model group( P〈0. 01). Compared with the model group,the proliferation of CFs were stimulated by AngⅡ,and the mRNA and protein expressions of type Ⅰ and Ⅲ collagen were inhibited by Pae group,NRS group,and the combined Pae and NRS high-dose and low-dose groups( P〈0. 05). The combined groups had better efffect than other groups,and the combined high-dose group had the best inhibitory effect. Conclusion: The combination of Pae and NRS can inhibit the gene expressions of type Ⅰ and Ⅲ collagen in cardiac fibroblasts induced by AngⅡ,and shows significant synergistic effects.
