摘　　要：目的:探讨miR17-92簇各成员在痛风患者外周血单个核细胞(PBMCs)中的表达,预测其可能靶点及作用通路,评估其在痛风中可能的作用机制及临床意义。方法:选取川北医学院附属医院67例痛风性关节炎(GA)患者,其中急性痛风性关节炎(AG)患者22例,间歇期痛风(IG)患者45例,对照组选取35例正常健康体检者(HC)。RT-qPCR检测miR17-92簇、IFN-γ、IL-10及JAK-STAT通路部分成员表达,收集相关实验室指标分析其相关性。结果:miR17、miR18a、miR19a、miR20a、miR19b在AG、IG、HC中表达差异均有统计学意义(H=8.753,P<0.05;H=6.338,P<0.05;H=6.523,P<0.05;H=9.061,P<0.05;H=9.729,P<0.01)。JAK3、STAT2在AG、IG、HC三组中表达差异有统计学意义(H=10.349,P<0.01;H=14.801,P<0.01)。IFN-γ在三组间表达差异有统计学意义(H=8.734,P<0.05)。AG患者miR18a表达与IBIL、Crea、MO、HGB呈负相关,miR19a表达与TC、UA、HGB呈负相关,miR20a表达与Crea呈负相关,miR19b表达与UA、HGB呈负相关。IG患者miR17表达与IBIL、WBC、LY、MO均呈负相关,miR18a表达与ALP呈正相关,miR19a表达与TC、UA呈负相关,miR20a表达与ADA、UA呈负相关。结论:miR17-92簇可能通过靶向JAK-STAT通路调控痛风发生发展、参与痛风临床生理病理过程。Objective:To explore expression of each member of miR17-92 cluster in peripheral blood mononuclear cells(PBMCs)of patients with gout,to predict their possible targets and pathways of action,and to evaluate their possible mechanism and clinical significance in gout.Methods:A total 67 gouty arthritis(GA)patients were selected,including 22 patients with acute gout arthritis(AG)and 45 patients with intermittent gout(IG),and 35 normal health control(HC)were selected in Affiliated Hospital of North Sichuan Medical College.RT-qPCR measured expressions of miR17-92 cluster,IFN-γ,IL-10 and some members of JAK-STAT pathway,and relevant laboratory indicators were collected to analyze correlation between each other.Results:Relative expressions of miR17,miR18a,miR19a,miR20a and miR19b were significantly changed in AG,IG and HC(H=8.753,P<0.05;H=6.338,P<0.05;H=6.523,P<0.05;H=9.061,P<0.05;H=9.729,P<0.01).JAK3 and STAT2 expressions were statistically different in AG,IG and HC groups(H=10.349,P<0.01;H=14.801,P<0.01).Expression of IFN-γwas statistically different among AG,IG and HC groups(H=8.734,P<0.05).In AG patients,miR18a expression was inversely correlated with IBIL,Crea,MO and HGB.miR19a ex-pression was negatively associated and TC,UA and HGB.miR20a expression was negatively associated with Crea.miR19b expression was negatively associated with UA and HGB.In IG patients,miR17 expression was negatively associated with IBIL,WBC,LY and MO.miR18a expression was positively associated with ALP,miR19a expression was negatively associated with TC and UA,and miR20a expression was negatively associated with ADA and UA.Conclusion:miR17-92 cluster may regulate development and partici-pate in clinical pathology of gout by targeting JAK-STAT pathway.
