摘要 目的探讨广东地区汉族人群TGF-β1(+915G/C)以及IL-1β(-31C/T)基因多态性及其与类风湿性关节炎(RA)相关性。方法分别采用PCR-SSP技术(TGF-β1+915G/C的检测)和PCR-RFLP技术(IL-1β-31C/T的检测)检测120例健康体检者和111例RA患者基因型。结果TGF-β1(+915)有GG、GC、CC3种基因型,健康体检者与RA患者间的基因型差异无统计学意义(2=0.05,P=0.975);IL-1β(-31)有CT、CC和TT3种基因型,健康体检者和RA患者间的基因型差异有统计学意义(2=8.86,P=0.012),且RA患者的C等位基因频率明显高于健康对照组(2=6.34,P=0.012,OR=1.64,95%CI:1.11~2.41);在RA患者组中,急性期患者的C等位基因频率亦明显高于缓解期的C等位基因频率(2=28.63,P=0.000,OR=6.87,95%CI:2.40~20.27)。结论TGF-β1(+915)基因多态性与RA无相关性;IL-1β(-31)基因多态性与RA具有相关性,且C等位基因可能是RA疾病的易感基因,CC基因型的人患RA疾病的概率较高。
