目的 观察雪莲通脉丸对冠心病气虚血瘀证小鼠内皮素-1（ET-1）、一氧化氮（NO）和血管紧张素转换酶（ACE）的调节作用。方法 建立冠心病气虚血瘀证小鼠模型,随机分为空白对照组、模型对照组、地奥心血康组和雪莲通脉丸组。给药4周后取小鼠血清,ELISA试剂盒测定ET-1、NO和ACE浓度。结果 与模型组比较,雪莲通脉丸组NO浓度显著升高,差异具有统计学意义（P〈0.01）;ET-1浓度降低,差异具有统计学意义（P〈0.05）;ACE浓度显著降低,差异具有统计学意义（P〈0.01）。与地奥心血康组比较,雪莲通脉丸组NO浓度显著升高,ACE浓度显著降低,差异具有统计学意义（P〈0.01）。结论 冠心病气虚血瘀证的发生可能与血管内皮细胞的功能指标具有相关性。其中,冠心病气虚血瘀证可能与血清ET-1、ACE浓度呈正相关、与血清NO浓度呈负相关。雪莲通脉丸对冠心病气虚血瘀证小鼠血管内皮细胞的功能指标具有调节作用,其机制可能与升高血清NO浓度、降低ET-1、ACE浓度有关,且与地奥心血康组比较在改善血清NO、ACE方面具有一定优势。

英文摘要：

Objective To observe the regulatory effects of Xuelian Tongmai Pill （XTP） on endothelin-1 （ET-1）, nitric oxide （NO） and angiotensin converting enzyme （ACE） in coronary heart disease mice models with Qi deficiency and blood stasis syndrome. Methods Coronary heart disease mice models with Qi deficiency and blood stasis syndrome were established and then distributed to blank control group, model control group, Di＇ao Xinxuekang group and XTP group. Serum of each group were picked after four weeks. The concentration of ET-1, NO and ACE were measured by ELISA. Results Compared with model group, concentration of NO was highly elevated with statistical significance （P〈0.01）; ET-1 was decreased with statistical significance （P〈0.05）; ACE was prominently decreased with statistical significance （P〈0.01）. Compared with Di＇ao Xinxuekang group, the concentration of NO was highly increased, while ACE was significantly decreased, the diffrences have statistical significance （P〈0.01）. Conclusion Morbidity of coronary disease with Qi deficiency and blood stasis syndrome may be related to the indicators of vascular endothelial cell function. Qi deficiency and blood stasis syndrome Serum concentration of showed positive relations with ET-1 and ACE, while negative relation with NO concentration. XTP showed regulatory function on the indicator of vascular endothelial cell function. The mechanism may be related to the increasing of serum concentration of NO and decreasing of ET-1 and ACE. In addition, XTP showed more advantages in improving serum NO and ACE concentration.
