Methods Left ventricular mass index (LVMI), intracardiac RAS andbFGF were determined at 0.5 h, 4h, 1day (1d), 5 days (5d), 10 days (10d) and 30 days (30d) afterabdominal aorta constriction in rats (OG) and compared with false operation rats (CG).

• 方法采用Wistar大鼠腹主动脉部分结扎组（OG），并与假手术组（CG）对比检测6个时相点（0.；5小时、4小时、1天、5天、10天和30天）的左心室重量指数（LVWI）、心肌局部bFGF和RAS。
