| 摘 要： | 目的观察COPADG对食管癌裸鼠肿瘤增殖与细胞凋亡的影响,并探讨其机制。方法建立人食管癌Eca-109裸鼠移植瘤模型并随机分为A、B、C、D四组,分别给予生理盐水、COPADG、5-FU、COPADG＋5-FU灌胃0.2ml,1次/d,连用28 d。测量动物体质量、肿瘤质量计算抑瘤率,采用免疫细胞化学法检测肿瘤组织中的Bcl-2、Caspase-3、PCNA。结果A、B、C、D组抑瘤率分别为0、54.16%、38.78%、73.91%,早期细胞凋亡率分别为6.02%、11.47%、13.05%、21.56%,晚期细胞凋亡率分别为12.65%、20.99%、13.23%、21.6%,B、C、D组与A组比较,P均〈0.01;D组抑瘤率与B、C组比较,P均〈0.01。与A组比较,B、C、D组Bcl-2、PCNA表达明显降低,Caspase-3表达明显增加（P均〈0.01）。结论COPADG可抑制食管癌裸鼠肿瘤增殖、诱导癌细胞凋亡,该作用可能与降低Bcl-2、PCNA表达以及增加Caspase-3表达有关。
