摘要 目的 研究腹腔化疗及联合使用重组人生长激素 (rhGH)对小鼠结肠癌肝转移的影响。方法  42只BALB/c小鼠以小鼠结肠癌细胞 (CT2 6 )经脾接种建立肝转移模型后随机分为 3组 ,化疗组小鼠每日腹膜腔注射 5 Fu 2 0mg/kg ;联合组在化疗组基础上每日皮下注射rhGH 2IU/kg ;对照组仅以生理盐水分别行皮下及腹膜腔注射 ,疗程 7天。 2周后部分动物处死 ,观察肝转移情况 ,其余动物待其自然死亡以比较生存期。 结果 联合组血浆总蛋白明显高于化疗组和对照组 (P <0 .0 1)。与对照组相比 ,化疗组和联合组的肝转移发生率较低 ,转移瘤数目较少 ,肝脏重量明显较低 (P <0 .0 5 ) ,小鼠生存期延长近一倍 (P <0 .0 5 )。联合组肿瘤细胞周期中静止期 (G0 /G1期 )细胞百分比高于其他两组 (P <0 .0 5 )。肿瘤细胞增殖指数 (PI)在联合使用rhGH组显著降低 (P <0 .0 5 )。 结论 腹腔化疗明显降低小鼠结肠癌肝转移的发生 ,延长生存期 ;给予rhGH可以调整细胞增殖周期 ,提高周期特异性化疗药物的敏感性 ,降低肿瘤细胞增殖活性。
