摘 要:目的评估载脂蛋白C-Ⅲ(Apolipoprotein,ApoC-Ⅲ)在溃疡性结肠炎(UC)的诊断及鉴别诊断中的作用。方法收集病理科2003~2011年存档的肠组织标本,UC组38例,克罗恩病(CD)组29例,肠结核组31例,肠淋巴瘤组32例,感染性肠炎组32例,白塞病组28例,正常体检组10例,采用免疫组化检测结肠黏膜的ApoC-Ⅲ表达情况,并用图像分析技术计数切片的阳性细胞数,取光学显微镜下的平均阳性细胞数作为计数标准。结果 UC患者肠粘膜组织中ApoC-Ⅲ的表达(44.44±10.71)显著高于肠结核组(20.76±4.77)、克罗恩病组(18.80±3.60)、肠淋巴瘤组(18.83±3.79)、白塞病组(19.02±3.04)、感染性肠炎组(20.56±3.35)和正常组(30.17±6.27,均P<0.05);正常组(30.17±6.27)又高于肠结核组(20.76±4.77)、克罗恩病组(18.80±3.60)、肠淋巴瘤组(18.83±3.79)、白塞病组(19.02±3.04)和感染性肠炎组(20.56±3.35,均P<0.05);但其它5组之间无差异(P>0.05)。结论 ApoC-Ⅲ在UC患者肠粘膜组织的表达较肠结核组、克罗恩病组、肠淋巴瘤组、白塞病组、感染性肠炎组和正常对照组明显增强,提示ApoC-Ⅲ与UC关系密切,可能与UC的发生发展过程相关,并在UC的诊断和鉴别诊断中起关键作用。Objective To evaluate the role of ApoC-Ⅲ in the diagnosis and differential diagnosis of UC. Methods Intestinal tissue samples were retrieved from 2003-2011 archived specimen at Department of Pathology, and assigned to UC group (n=38), CD group (n=29), ITB group (n=31), IL group (n=32), infectious enteritis group (n=32) and Behcet's disease group(n=28). 10 cases were recruited as normal control group. The expression of ApoC-± in colonic mucosa were detected by immunohistochemistry. Positive cells were counted by Image Analysis. Results The expression rate of ApoC-Ⅲ in intestinal mucosa of UC patients(44.44±10.71)was significantly higher than that of ITB(20.76±4.77), CD (18.80±3.60) , IL(18. 83±3. 79) , Behcet's disease(19.02±3.04), Infectious enteritis (20.56+3.35) and normal control(30. 17±6.27)(p〈0.05). That of normal control(30. 17±6.27) was higher than ITB(20. 76±4. 77) , CD(18.80±3.60) , IL(18.83±3.79) , Behcet's disease(19.02±3.04) , Infectious enteritis(20.56±3.35) (p〈0.05). While there was no significant difference among the other five groups(p〈0.05). Conclusion ApoC-Ⅲ is related with UC closely, and may play an imoortant role in the !oathogenesis, diagnosis and differential diagnosis of UC.
