摘要
目的了解血管生成素样蛋白(ANGPTL)3及ANGPTL4在RA患者血清中的表达情况,初步探讨ANGPTL3、ANGPTL4与RA临床表现及实验室指标的相关性。方法收集72例RA患者及28例健康体检者血清及临床资料,应用ELISA检测血清ANGPTL3、ANGPTL4、NF-κB受体活化因子配体(RANKL)水平,组间数据比较采用非参数秩和检验,两因素间关系采用Spearman相关分析。结果①RA患者血清ANGPTL3水平较对照升高[800.325(577.477,1 750.636)pg/ml和487.900(382.340,565.499)pg/ml,Z=-6.082,P<0.05];RA患者血清ANGPTL4水平较对照升高[1 036.199(853.347,1 746.677)pg/ml和706.095(558.571,807.302)pg/ml,Z=-5.962,P<0.05];②RA患者血清ANGPTL3、ANGPTL4水平随疾病活动加重而升高[ANGPTL3:低活动组457.265(373.709,605.296)pg/ml,中活动组785.815(679.156,1 308.785)pg/ml,高活动组1 502.038(817.713,1 960.493)pg/ml,P<0.05;ANGPTL4:低活动组737.604(467.040,918.222)pg/ml,中活动组991.227(819.456,1 699.972)pg/ml,高活动组1 842.310(1 252.023,2 669.902)pg/m1,P<0.05];③RA患者血清ANGPTL3、ANGPTL4与RANKL呈正相关(r分别为0.554、0.619,P<0.05);④RA患者双手加腕关节X线片提示无骨破坏者血清ANGPTL4水平低于有骨破坏者[927.590(737.604,1409.798)pg/ml和1 624.071(949.432,2 622.371)pg/ml,Z=-2.483,P<0.05]。结论RA患者血清ANGPTL3、ANGPTL4水平显著升高,二者与疾病活动性相关,后者还与骨破坏相关,可能成为判断疾病活动及骨破坏的新指标。
