目的检测热休克转录因子2(HSF2)在溃疡性结肠炎(UC)、克罗恩病、肠结核、肠淋巴瘤、感染性肠炎、白塞病及正常结肠黏膜中的表达情况。方法收集病理科2003年至2011年存档的肠组织标本:UC组38例,克罗恩病组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HSF2的表达情况。采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患者结肠黏膜组织中HSF2的表达(64.64±15.17)明显高于其他6组(克罗恩病组、肠结核组、肠淋巴瘤组、感染性肠炎组、白塞病组、正常体检组)(32.44±5.94、36.93±6.32、36.16±6.55、37.86±7.76、34.90±5.92、35.54±6.76,P〈0.05),而这6组间差异无统计学意义(P〉0.05)。结论HSF2在UC患者结肠黏膜组织的表达较克罗恩病组、肠结核组、肠淋巴瘤组、感染性肠炎组、白塞病组及正常体检组明显增强,提示HSF2与UC关系密切,HSF2可能对UC的发病、诊断和鉴别诊断起重要作用。
Objective To investigate the expression of HSF2 in colonic mucosa of patients with ul- cerative colitis (UC), Crohn's disease ( C D), intestinal tuberculosis ( ITB), intestinal lymphoma ( IL), infectious enteritis, Behcetg disease and normal control. Methods Intestinal tissue samples were retrieved from 2003 -2011 archived specimen at the 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 Beh- cet's disease group (n =28). 10 cases were recruited as normal control group. The expression of HSF2 in colonic mucosa were detected by immunohistochemistry. Positive cells were counted by Image Analysis. Re- suits The expression rate of HSF2 in intestinal mucosa of UC patients ( 64. 64 ±15.17 ) was significantly higher than that of CD ( 32.44± 5.94 ), ITB ( 36. 93 ±6. 32 ), IL ( 36. 16 ±6. 55 ), infectious enteritis (37.86 ±7. 76), Behcet's disease (34. 90 ±5.92) and normal control (35.54 ±6. 76) (P 〈0. 05), while there was no significant difference among the latter six groups ( P 〉 0. 05 ). Conclusion HSF2 is closely re- lated with UC, and may play an important role in the pathogenesis, diagnosis and differential diagnosis of UC.
