Abstract:
Objective:To observe expression level change of miRNA?126 in the myocardial tissue of rats with myocardial infarction and to observe the influence of Shuxuetong injection. Methods:Myocardial infarction model was established in 80 SD rats, 60 surviv?al rats were randomly divided into Shuxuetong group and model group, the other 30 rats were randomly selected as control group. After the success of the modeling, Shuxuetong group received Shuxuetong injection treatment, model group and control group received same amount of normal saline. Real?time quantitative PCR was used to detect miRNA?126 expression levels in rat myocardial tissue at dife?rent time after operation. Results: After 7 days and 14 days, miRNA?126 expression levels in rats myocardial tissue in Shuxuetong group and model group were significantly lower than that in the control group ( P<0?05) , but there was no difference between the two groups. After 14 days, miRNA?126 expression levels in the Shuxuetong group were higher than that after 7 days ( P<0?05) . Conclu?sions:miRNA?126 in 7 days after myocardial infarction significantly reduced. With the passing of time, miRNA?126 expression levels increased gradually and Shuxuetong can increase the expression levels of miRNA?126 .
