摘要: 目的:探讨Caspase-8在原发性干燥综合征唇腺组织中的表达及意义,并分析它的表达与临床特征的相关性。方法:采用免疫组化和Western blotting的方法检测55例原发性干燥综合征患者和15例健康者唇腺组织中Caspase-8蛋白的表达,测量吸光度值,采用SPSS14.0软件包对两组结果进行统计学分析。结果 原发性干燥综合征唇腺组织中Caspase-8在蛋白水平上有表达,与健康对照组相比明显升高(P<0.05),并与疾病的病程呈正相关,但与其他临床特征之间不存在明显相关性。结论:Caspase-8在原发性干燥综合征患者唇腺组织中高表达,且与疾病的病程相关,Caspase-8介导的细胞凋亡途径可能参与了原发性干燥综合征的发病过程。

Abstract: PURPOSE:To explore the expression and significance of Caspase-8 in the labial glands of patients with primary Sjogren’s Syndrome(pSS). Analysis the relationship between the expression of them and the clinical manifestations in pSS.METHODS:Fivty-five cases with pSS and fifteen controls were collected.Immunohistochemistry and Western blotting were used to examine Caspase-8 protein in labial glands of two groups,the IOD and the A were measured and the data were analyzed by statistical analysis.RESULTS:The expression of Caspase-8 protein in pSS was positively correlated with the disease course and significantly higher than those in control group(P<0.05),but has no correlation with the other clinical manifestations.CONCLUSIONS:The expression of Caspase-8 in pSS was increased,which was related to the disease course. Apoptosis pathway mediated by Caspase-8 may contribute to the formation and progression of pSS.
