摘要：

目的　运用超声心动图评价粒细胞集落刺激因子(granulocyte colonystimulatingfactor,G CSF)动员自体骨髓干细胞对大鼠心肌梗死(心梗)后左室重构及心功能的影响。方法　40只雄性SD大鼠随机分成G CSF治疗组(16只)、对照组(16只)和假手术组(8只)。治疗组及对照组结扎大鼠冠状动脉左前降支,造成大鼠急性前壁心梗。假手术组仅单纯开胸。心梗后6h起治疗组给予皮下注射G CSF150 μg·kg-1·d-1共5d,其余两组给予生理盐水。心梗前、心梗后1d、2周及6周运用超声心动图评价左室形态及心功能变化。心梗后6周处死大鼠,取出心脏,测量并比较治疗组及对照组的心肌瘢痕指数。结果心肌梗死后6周,与对照组相比,治疗组的左室舒张末期内径(LVDd)和左室收缩末期内径(LVDs)明显减小[LVDd(0.72±0.03)cm对(0.83±0.02)cm,P=0.006;LVDs(0.34±0.03)cm对(0.55±0.03)cm, P<0.001];左室射血分数(LVEF)、缩短分数(FS)则显著增高[LVEF(87.6±2.9)%对(62.5±2.5)%; FS(52.7±2.4)%对(30.6±2.0)%,P均<0.001];Tei指数则明显降低(0.23±0.06对0.44±0.05,P =0.009)。心梗后6周治疗组的瘢痕指数亦较对照组明显降低[(37.3±11.0)%对(51.9±11.5)%,P< 0.05]。结论　G CSF动员自身骨髓干细胞减轻左室重构,改善心功能。超声心动图可
