摘要
目的研究痛风性关节炎患者外周血单个核细胞中端粒重复序列结合蛋白1(TRF1)、端粒重复序列结合蛋白2(TRF2)及核苷酸结合寡聚化结构域样受体3(NLRP3)炎性体的变化趋势。方法选择2013年6月2015年3月在绵阳市中心医院就诊的急性期(30例)、慢性期(30例)、间歇期(30例)痛风性关节炎90患者,另选择30例健康者为对照,采集外周血单个核细胞并检测NLRP3、凋亡相关斑点样蛋白(ASC)、半胱氨酸天冬氨酸蛋白酶1(Caspase1)、TRF1、TRF2、淋巴细胞功能相关抗原(LFA1)含量,采集血清并检测血清中白介素1β(IL-1β)含量。结果痛风性关节炎患者外周血单个核细胞中NLRP3、ASC、Caspase1、TRF1、TRF2、LFA1的m RNA含量以及IL-1β含量均高于健康者,差异有统计学意义(P<0.05);急性期患者外周血单个核细胞中NLRP3、ASC、Caspase1、TRF1、TRF2、LFA1的m RNA含量以及血清中IL-1β含量高于慢性期和间歇期患者,差异有统计学意义(P<0.05);慢性期患者外周血单个核细胞中NLRP3、ASC、Caspase1、TRF1、TRF2、LFA1的m RNA含量以及血清中IL-1β含量高于间歇期患者,差异有统计学意义(P<0.05)。血清中IL-1β含量与外周血单个核细胞中NLRP3、ASC、Caspase1的含量呈正相关(r=0.882、0.718、0.784,P<0.05);外周血中LFA-1含量与外周血单个核细胞中TRF1、TRF2的含量呈正相关(r=0.748、0.842,P<0.05)。结论痛风性关节炎患者外周血单个核细胞中TRF1、TRF2及NLRP3炎性体的表达增多,能够通过调节炎症和免疫反应来参与病情的发展。
