Abstract:
Objective　To study the effect of rosuvastatin（ROS） on the proliferation and apoptosis of atrial fibroblasts in patients with rheumatic heart disease and atrial fibrillation（AF） in vitro.Methods　Fifty patients with rheumatic heart disease and permanent AF in the Department of Cardiovascular Surgery of the First Affiliated Hospital of Xinxiang Medical University from January to December 2018 were selected as the study objects.The left auricular tissue of patients was obtained and the degree of fibrosis was observed by Massion staining.Then the fibroblasts isolated from the left auricular tissue and then were divided into control group,10-5 mol·L-1ROS，10-6 mol·L-1 ROS group，10-7 mol·L-1 ROS group,10-5 mol·L-1 ROS+10-5 mol·L-1 farnesyl pyrophosphate (FPP) group， 10-6 mol·L-1 ROS+10-5 mol·L-1 FPP group,10-7 mol·L-1 ROS+10-5 mol·L-1 FPP group.The cells in above intervention groups were given 100 μL Dulbecco′s modified Eagle medium(DMEM) containing the corresponding final concentration of the above drugs and co-cultured for 72 hours;the cells in control group were given the same volume of DMEM medium containing 10% fetal bovine serum.The proliferation and DNA synthesis of the fibroblasts were measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and Edu method respectively.The expression of apoptosis related genes were detected by real-time fluorescence quantitative polymerase chain reaction.Results　The left auricular tissue of the patients with rheumatic heart disease and permanent AF showed the obvious proliferation of fibroblasts and some cardiac myocytes appeared apoptosis and dissolution.The collagen volume fraction was （10.25±1.10）%.The proliferation ability of fibroblasts in all intervention groups was lower than that in the control group (P<0.05),the proliferation ability of fibroblasts in 10-7 mol·L-1 ROS + 10-5 mol·L-1 FPP group,10-6 mol·L-1 ROS + 10-5 mol·L-1 FPP group,10-5 mol·L-1 ROS + 10-5 mol·L-1 FPP group was higher than that in the corresponding concentration ROS group (P<0.05).The DNA synthesize rate of fibroblasts in all intervention groups was lower than that in the control group (P<0.05),the DNA synthesize rate of fibroblasts in 10-7 mol·L-1 ROS + 10-5 mol·L-1 FPP group,10-6 mol·L-1 ROS + 10-5 mol·L-1 FPP group,10-5 mol·L-1 ROS + 10-5 mol·L-1 FPP group was higher than that in the corresponding concentration ROS group (P< 0.05).The relative expression of anti-apoptosis genes Bcl-2 and inhibitor of apoptosis protein 1(IAP-1) in fibroblasts in all intervention groups was lower than that in the control group (P<0.05),the relative expression of proapoptotic genes Bax and Smac was higher than that in the control group (P<0.05).The relative expression of Bcl-2 and IAP-1 in the 10-7 mol·L-1 ROS + 10-5 mol·L-1 FPP group,10-6 mol·L-1 ROS + 10-5 mol·L-1 FPP group,10-5 mol·L-1 ROS + 10-5 mol·L-1 FPP group was higher than that in the corresponding concentration ROS group (P<0.05),the relative expression of Bax and Smac was higher than that in the corresponding concentration ROS group (P<0.05).Conclusion　There is obvious fibrosis in the left atrium tissue of patients with rheumatic heart disease and AF,and the ROS can inhibit the proliferation of fibroblasts and promote its apoptosis.
