简介：目的探讨微小染色体维持蛋白5（MCM5）在胃癌组织中的表达及其意义。方法用免疫组织化学SP方法检测21例胃溃疡组织、30例不同时期胃癌组织中MCM5的表达。结果MCM5高表达于胃癌细胞核，胃癌组织中的MCM5表达率为63.3%（19/30），胃溃疡组织中MCM5表达率4.7%（1/21），两者相比差异有统计学意义（P〈0.05）；Ⅳ期胃癌患者的MCM5表达明显高于Ⅱ-Ⅲ期的表达（P〉0.05），Ⅱ-Ⅲ期的表达明显高于Ⅰ期（P〈0.01）。结论MCM5与胃癌发生、发展相关，可作为新的胃癌增殖标志物。

简介：目的：探讨腹腔镜结合“蓝碟”行双原发结直肠癌手术技巧及临床疗效。方法回顾性分析2009年9月至2014年5月唐山市人民医院胃肠外科应用腹腔镜与“蓝碟”相结合对5例双原发结直肠癌患者实施双原发癌根治性手术的临床资料。结果5例患者手术均获得成功，无1例中转开腹，无围手术期死亡，手术平均时间185min；术中平均出血115ml，切除淋巴结总数平均为30个。术后恢复良好，无切口感染、吻合口瘘等并发症。结论对于无远处转移的同时性双原发结直肠癌应用腹腔镜与“蓝碟”相结合实施双原发癌根治性切除手术，安全、可行，可减轻对患者的创伤，并可以获得良好的治疗效果。
