摘　　要：目的 比较3种不同的人大肠癌裸鼠原位种植肝转移模型,建立稳定有效的人大肠癌裸鼠原位种植肝转移模型.方法 逐步传代法皮下成瘤传5代,采用84只BALB/C-nu/nu裸鼠,随机分为4组,结肠原位荷包缝合法和结肠原位纤维蛋白胶黏合法和结肠微注射1×10^6和1×10^5SW1116细胞法建立大肠癌裸鼠原位种植肝转移模型.各组裸鼠死亡后立即解剖观察原位以及肝脏、肺、脾脏、胰腺、肠系膜等脏器组织的转移并且进行苏木素-伊红（HE）染色进行镜下观察有无转移.结果 荷包缝合组和纤维蛋白胶组结肠原位种植肝转移成功率均为100%比微注射法50.0%和14.3%高,纤维蛋白胶法比其他两种方法所形成的结肠原位肿瘤和肝转移瘤均大而多.HE染色表明肝转移肿瘤性质与结肠原位种植瘤相同.结论 结肠原位纤维蛋白胶黏合法比较其他二种原位种植肝转移模型的手术成功率高,肝转移率高、操作简单.Objective To establish and compare three orthotopic implantation nude mice models of colorectal cancer metastasis to liver. Methods Human SW1116 cell line was inoculated into 5 BALB/ C nude mice. Eighty-four nude mice were divided equally into pouch, fibrin glue, 1×106 cell and 1 × 105 cell microinjection groups. After animals were killed, the metastasis of cancer in situ, the liver, the lung, the spleen, the pancreas, and the mesentery was observed under the microscopy after HE staining. Results The metastasis rate in groups of pouch, fibrin glue, 1×1106 cell and 1×105 cell microinjection was 100% , 100% , 50. 0% and 14. 3% respectively. The liver metastasis tumor in fibrin glue group was bigger than other groups. HE staining indicated that the liver metastasis tumor was derived from colon tumor. Conclusion Among the three orthotopic implantation nude mice models of colorectal cancer metastasis to liver, the fibrin glue method has a high success rate of operation, a high metastasis rate of the liver, and is simple to manipulate.
