医药学论文：心脉通胶囊对冠心病患者心肌缺血总负荷影响及其作用机制探讨

内容提要　目的：观察心脉通胶囊对缺血性心脏病的治疗作用。方法：60例冠心病心肌缺血患者随机分为心脉通组(30例，常规西药加心脉通胶囊治疗)与对照组(30例，单用常规西药治疗)，观察治疗前后临床症状计分、心肌缺血总负荷(TIB)、血浆内皮素(ET)、一氧化氮(NO)和血清超氧化物歧化酶(SOD)、丙二醛(MDA)的变化。结果：治疗后心脉通组临床症状计分、TIB、ET、MDA下降幅度明显大于对照组(P＜0.01)，NO、SOD上升水平明显高于对照组(P＜0.01)。结论：心脉通胶囊有较好抗心肌缺血作用，血管内皮保护效应及抗脂质过氧化损伤是其作用机理之一，加用心脉通胶囊治疗缺血性心脏病比单用西药效果更好。

　　Objective: To assess the effect of Xinmaitong (XMT) capsule in treating ischemial cardiac disease.Methods: Sixty coronary heart disease (CHD) patients with myocardial ischemia were divided randomly into two groups. XMT group (30 cases) was treated with XMT plus western medicine, and control group (30 cases) with western medicine alone. The changes of the scores for clinical symptoms, the total ischemia burden (TIB), the plasma endothelin (ET), the nitric oxide (NO), the superoxide dismutase (SOD), and the malonyldialdeyde (MDA) levels were observed before and after treatment.Results: After treatment with XMT the scores of clinica l symptoms, TIB, ET and MDA levels were significantly decreased (P＜0.01), the levels of NO and SOD were significantly increased (P＜0.01) in the XMT group, comparing with the control group these changes were statistically different (P＜0.01).Conclusions: XMT capsule can act against myocardial ischemia effectively, one of the mechanisms of which is protecting the function of vascular endothelium and resisting lipid peroxidation injury. The effects of adding XMT capsule on conventional treatment of western medicine were better than those of using western medicine alone.
