摘　　要：目的:研究黏蛋白(MUC2)在结肠正常组织、结肠良性腺瘤组织和结肠癌组织中的表达状况,以及MUC2的表达情况与结肠癌患者临床资料的关联。方法:选择2011年3月-2015年3月本院手术切除的结肠正常组织15例,结肠良性腺瘤组织41例及结肠癌组织121例,应用免疫组织化学技术检测MUC2在不同组织中的表达。结果:(1)MUC2在结肠正常组织、结肠良性腺瘤组织和结肠癌组织中的阳性表达率分别为100%(15/15)、73.17%(30/41)和46.28%(56/121),不同组织中MUC2阳性表达率比较,差异有统计学意义(P<0.01)。(2)MUC2高表达的结肠癌患者组织分型、淋巴结转移及肿瘤分期均优于MUC2低表达患者,比较差异均有统计学意义(P<0.05)。结论:结肠癌中MUC2的表达状况与组织分型、淋巴结转移和肿瘤分期有关。MUC2的表达下调可能参与了结肠癌的发生、发展、浸润和转移等过程。Objective：To investigate the expression of MUC2 in normal colorectal tissue,colorectal adenomas and colorectal carcinomas,and to explore the relation between the expression of MUC2 and its associated clinical data.Method：15 cases of normal colorectal tissues,41 cases of colorectal adenomas tissues and 121 cases of colorectal carcinomas tissues in our hospital were selected from March 2011 to March 2015.The expression of MUC2 in different tissues were detected by immunohistochemistry.Result：（1）The positive expression rates of MUC2 in normal colorectal tissues,colorectal adenomas tissues and colorectal carcinomas tissues were 100%（15/15）,73.17%（30/41） and 46.28%（56/121） respectively.The differences of the positive expression rates in different tissues were statistically significant（P〈0.01）.（2）The histological differentiation,lymph node metastasis and tumor stage in patients with high expression rates of MUC2 were better than those in patients with low expression rates of MUC2,the differences were statistically significant（P〈0.05）.Conclusion：The expression of MUC2 in colorectal carcinomas has relationships with histological differentiation,lymph node metastasis and tumor stage.The down-regulation of MUC2 expression may play a role in the carcinogenesis,progression,infiltration,metastasis and other processes of colorectal carcinomas.
