摘 要: | 目的探讨兔冠状动脉微栓塞(CME)后血清肌钙蛋白Ⅰ与血液动力学的关系以及通心络的保护作用。方法日本大耳白兔40只随机分为假手术组、CME组、联合组(通心络+阿司匹林+阿托伐他汀)、非联合组(阿司匹林+阿托伐他汀)。采用酶联荧光分析法检测术前和术后6 h的cTnI数值,颈动脉插管连续观察血液动力学变化。结果 (1)血清cTnI水平:与术前比较,手术后假手术组无显著变化,CME组、联合组、非联合组均显著增高(P<0.05),联合组与非联合组比较差异亦有统计学意义(P<0.05)。(2)血液动力学变化:与术前比较,手术后假手术组仅左室收缩压(LVSP)明显降低,CME组、联合组、非联合组各项指标均降低(P<0.05,P<0.01),与CME组比较,联合组、非联合组均增高(P<0.05,P<0.01),且联合组、非联合组比较差异亦有统计学意义(P<0.01)。(3)相关性分析:除联合组-dp/dtmax外,各组LVSP、-dp/dtmax、dp/dtmax均与血清cTnI水平呈负相关(P<0.05,P<0.01)。结论阿司匹林、阿托伐他汀联合通心络可减轻兔冠状动脉微栓塞后心功能损害。

Abstract: | Objective To investigate the relationship between cTnl and hemodynamic changes and the protective effect of Tongxinuo after coronary micro-embolization(CME) in rats model.Methods 40 Japanese white rabbits randomly divided into sham operation group,CME group,combination Tongxinluo group(Tongxinluo + aspirin + atorvastatin ),noncombination group(Aspirin + atorvastatin ).ELISA assay using fluorescence were applied to analyze preoperative and postoperative cTnI values for 6 h,continuous observation of carotid artery hemodynamics was also applied.Results(1) Serum cTnI is significant negative correlation with hemodynamic(P 0.05).Combination Tongxinluo further reduced myocardial injury after CME(P 0.05).(2) Hemodynamic changes;compared with the preoperative,sham surgery group only left ventricular systolic pressure(LVSP) decreased significantly,CME group,the joint group,non-union group,the indicators are lower(P 0.05,P 0.01),compared with the CME group,combination group,non-combination group were significantly higher(P 0.05,P 0.01),and the combined group,non-union group difference was also statistically significant (P 0.0I).(3) Correlation analysis:in addition to the combined group -dp/dt_(max),each group of LVSP,-dp/dt_(max),dp/ dt_(max) and serum cTnI levels were negatively correlated(P 0.05,P 0.01).Conclusion Aspirin,atorvastatin combined with Tongxinluo reduces rabbit ventricular function after coronary microembolization damage. |
