本研究旨在探讨不同剂量复方丹参滴丸对缺血-再灌注大鼠心功能的作用及可能机制。
方法
2
32只雄性SD大鼠经结扎左冠状动脉前降支,45min后进行再灌注以构建大鼠心肌缺血-再灌注模型,之后随机分为以下4组(每组8只):不同剂量复方丹参滴丸组(以40、80、120 mg·kg

剂量灌胃给药)及空白对照组(给予等量生理盐水)。另8只大鼠进行相似的操作但不结扎左前降支为假手术组(给予等量生理盐水灌胃)。灌胃给药持续4周。以超声心动图检查评估心功能,HE和Masson三色染色以观察组织形态学变化,CD31/α-SMA免疫荧光以分析鼠心微血管的内皮-间质转化情况,Western blot以检测梗死周边心室组织CD31/α-SMA的表达。用单因素方差分析或Kruskal-Wallis

Objective
2
The present study was conducted to investigate the protective effect on cardiac function and potential mechanism of Compound Danshen Dripping Pills (CDDPs) on myocardial ischemia reperfusion in rats.
Methods
2
Thirty two male SD rats were underwent cardiac reperfusion following 45 minutes of left anterior descending coronary artery ligation, and randomly divided into 4 groups (
n
= 8 ), rats in each group were given different doses of CDDPs (40,80,120 mg·kg
-1
·d
-1
), or normal saline (control group) by gavage. Another 8 rats underwent similar procedure but without LAD ligation were set as sham group (were also given same volume of normal saline by gavage). The treatment lasted for 4 weeks. Then echocardiography was conducted to evaluate the end-point cardiac function. HE and Masson’s trichrome staining were performed to observe the change of histomorphology and fibrosis. CD31/α-SMA immunofluorescence was implemented to investigate the endothelial to mesenchymal transition in cardiac microvessels. Western Blot was used to analyze the expression of α-SMA and CD31 in ventricular tissue of infarcted border zone. Data were analyzed by one-way ANOVA or Kruskal-Wallis
H
non-parametric test.
Results
2
Compared with normal saline group, treatment with different doses of CDDP could increase ejection fraction and fractional shortening significantly (
P
<0.05 at least), decrease left ventricular end-diastolic volume and the E/A ratio significantly (
P
<0.05 at least), reduce the cardiac collagen volume fraction (both
P
<
0.05), and suppress the expression of mesenchymal marker α-SMA in cardiac microvessels detected by immunofluorescent staining(
P
<0.05 at least), and decrease the expression of α-SMA and increase the expression of CD31 in ventricular tissue of infarcted border zone detected by Western blot.
Conclusion

doses of CDDPs for 4 weeks could improve cardiac function in rats underwent ischemia-reperfusion, this might be through reducing the occurrence of endothelial to mesenchymal transition in microvessels within heart tissue, and subsequently decreasing the cardiac fibrosis.
