方法：采用逆转录巢式酶链免疫反应，对41例结直肠癌组织及其配对的癌旁正常组织和25例良性腺瘤的FHIT基因进行检测。
Methods: Matched normal and cancerous tissues from 41 patients with colorectal cancer and 25 patients with colorectal adenoma were examined for FHIT expression using RT-PCR.
方法用SP法进行石蜡切片免疫组化染色，检测57例直肠癌组织、46例癌旁组织及20例正常直肠组织中P 16蛋白的表达。
Methods The expression of P16 protein in 57 cases of rectum cancer, 46 cases of adjacent tissue and 20 cases of normal rectum tissue was tested by immunohistochemical SP method.
结果：与癌旁正常组织相比，结肠直肠癌组织表达较高水平的CD 133。
Results Stronger expression of CD133 was observed in colorectal carcinoma specimens, compared with that in normal tissues.
