摘要 目的通过观察养心颗粒对近似不稳定型心绞痛家兔模型血脂含量的影响,探讨其防治不稳定型心绞痛的确切作用机制。方法家兔35只随机分为空白组、模型组、养心颗粒组、异山梨酯(消心痛)组、阿托伐他汀组。应用球囊损伤颈总动脉、高脂饮食喂养和药物触发的方法复制成近似人类不稳定型心绞痛动物模型。采用酶标法检测血脂含量。结果8周末各造模组三酰甘油(TG)、总胆固醇(TC)、低密度脂蛋白(LDLC)明显升高,高密度脂蛋白(HDLC)明显降低,与空白组比较差异有统计学意义(P<0.01);养心颗粒组TC、LDLC降低,与8周末比较差异有统计学意义(P<0.05),TG、HDLC与8周末比较无统计学意义(P>0.05);消心痛组各项指标均无统计学意义(P>0.05);阿托伐他汀组TG、TC、LDLC明显降低,HDLC升高,与8周末比较差异有统计学意义(P<0.05)。结论养心颗粒可明显降低实验模型的血脂水平,从而减轻高脂血症损害动脉壁内皮依赖性血管舒张功能,这可能是养心颗粒防治不稳定型心绞痛的作用机制之一。
