摘  要:目的探讨新疆维吾尔族类风湿关节炎与HLA—DR4基因的相关性。方法采用特异性引物一聚合酶链反应(PCR—SSP)对新疆维吾尔族157例类风湿关节炎患者和118例健康人的HLA—DR4基因进行检测。结果HLA—DR4基因在维吾尔族类风湿关节炎患者和健康人群中基因频率分别为41.4%和28.8%,两组比较差异有统计学意义(P〈0.05)。在类风湿关节炎患者中,HLA.DR4基因阳性组与阴性组在性别、发病年龄比较差异无统计学意义(P〉0.05),将病程分为≤2年和〉2年组,差异有统计学意义(P〈0.01);HLA—DR4基因阳性组与阴性组在血沉、C反应蛋白、抗CCP抗体比较差异无统计学意义(P〉0.05),两组类风湿因子比较差异有统计学意义(P〈0.05),HLA—DR4阳性组与阴性组在晨僵、关节压痛数、关节肿胀数、双手x线片骨破坏等方面比较差异均无统计学意义(P〉0.05)。结论HLA—DR4基因是新疆维吾尔族人群类风湿关节炎的易感基因,与国内汉族类风湿关节炎患者HLA—DR4阳性率34%~62%报道结果基本一致。Objective To analyze the HLA-DR4 gene associations with RA in the Uygur nation- ality of Xinjiang region. Methods The methods of DNA amplification with sequence specific primers-pol- ymerase chain reaction(PCR-SSP) was used to determine the ttLA-DR4 gene in 157 RA patients and 118 heahhy controls from the Uygur nationality of Xinjiang region. Results The frequency of HLA-DR4 was 41.4% in Uygur nationality and 28.8% in healthy control group of Xinjiang region(P 〈0.05). There is no statistically significant difference in sex,age of onset between the DR4 + and DR4- in RA patients(P 〉0.05 ) ,the diffcrence was significant in duration of disease between ≤2 years and 〉2 years in RA pa- tients (P 〈 0.01 ) ;There is no difference in ESR, CRP, anti-CCP between the DR4 + and DR4- in RA pa- tients( P 〉 0.05 ) , the difference was signifcant in RF( P 〈 0.05 ) ;There is no difference in morning stiff- ness,the pain number of joints,the swell numher of joints and X-ray about osteoclasia(P 〉 0.05). Con- clusion HLA-DR4 gene is the p,'edisposing gene for RA in the Xinjiang Uygur patients. Its positive rate is ahnost consistent with the reported results for Chinese Han RA patients(34%-62% ).
