摘要
目的探讨膝关节骨性关节炎(KOA)患者关节液中差异表达的微小RNA(miRNAs)及其临床意义。方法选择KOA患者和体检健康者各33例,均为女性。采集受试者关节液标本,随机从中各选择3例份,采用miRNA芯片技术检测差异表达的miRNAs(差异表达的标准定义为上调或下调≥2倍)。采用Real-time PCR法检测剩余KOA患者和体检健康者关节液(各30例份)中差异表达miRNAs的相对表达量,对芯片检测结果进行验证。结果与体检健康者比较,KOA患者关节液中上调≥2倍的miRNAs有3个(miR-9、miR-155、miR-98),下调≥2倍的miRNAs有4个(miR-140、miR-27a、miR-146a、miR-138)。KOA患者关节液miR-9、miR-155、miR-98相对表达量均高于体检健康者,miR-140、miR-27a、miR-146a和miR-138相对表达量均低于体检健康者(P均<0.05)。结论 KOA患者关节液miR-9、miR-155、miR-98表达升高,miR-140、miR-27a、miR-146a和miR-138表达降低;上述miRNAs表达变化可能与KOA的发病有关。
