强直性脊柱炎患者外周血可溶性CD146的表达及意义

背景:研究发现在炎症因子的刺激下内皮细胞和活化的T细胞表面表达CD146显著增加,故推测CD146可能参与了组织的炎症反应.目的:观察强直性脊柱炎患者外周血可溶性CD146的表达水平和临床意义.方法:选择上海交通大学附属第六人民医院住院的强直性脊柱炎患者62例,分为两组.活动期组46例,非活动组16例.同时选择同期医院健康职工和大学生20名为对照组.在强直性脊柱炎患者初诊时评估BASDAI、BASFI、强直性脊柱炎患者总体评分(PGA)、夜间痛、总体背痛评分、晨僵时间并测定红细胞沉降率、C-反应蛋白水平.应用ELISA法检测62例强直性脊柱炎患者与20例正常人外周血可溶性CD146的表达水平、魏氏法测定血沉及免疫比浊法测定C-反应蛋白.对强直性脊柱炎患者可溶性CD146与各项检测指标相关分析.结果与结论:强直性脊柱炎患者的外周血清可溶性CD146的表达水平较正常对照组显著增高(P＜0.05):活动期强直性脊柱炎患者可溶性CD146的表达水平较非活动期和正常对照组显著增高(P＜0.05);强直性脊柱炎患者血清可溶性CD146的表达水平与BASDAI呈正相关(P＜0.05);累及外周关节型者血清可溶性CD146较单独中轴型强直性脊柱炎患者和正常对照组显著增高(P＜0.05).结果表明,外周可溶性CD146表达水平的增加与强直性脊柱炎患者疾病的活动性有关,其可能参与了强直性脊柱炎的发病过程.

Significance and expression of soluble CD146 in peripheral blood from patients with ankylosing spondlitis

BACKGROUND: Research has been reported that serum soluble CD146 (sCD146) expression was improved on the surface of endothelial cells and activated T cells by the stimulation of inflammatory factor. Therefore, it predicts that CD146 may participate in inflammatory reaction of tissue. OBJECTIVE: To investigate the expression and clinical significance of serum sCD146 in peripheral blood from patients with ankylosing spondylitis. METHODS: A total of 62 patients with ankylosing spondylitis were selected from the...
