摘要 目的:研究肿瘤坏死因子β(TNFβ)基因多态性与西方型、亚洲型多发性硬化(MS)的相关性。方法:采用聚合酶链式反应-限制性片段长度多态性(PCR-RFLP)技术对22例西方型MS患者、36例亚洲型MS患者和79名健康人进行TNFβ基因多态性分析。对两型MS组患者分别进行神经功能缺损程度的扩展病残状态(EDSS)评分、首发年龄、病程、发病次数等临床资料收集。结果:①亚洲型MS组TNFβ1等位基因频率为51.39%,较健康人(27.85%)明显升高(P<0.01)。②西方型MS组与亚洲型MS组基因型为TNFβ1/1、TNFβ1/2、TNFβ2/2的EDSS评分组间比较差异均无统计学意义(P>0.05)。③两亚型在EDSS评分、首发年龄、性别、病程、发病次数诸方面均无统计学意义。结论:TNFβ1等位基因与亚洲型MS的易患性有关。TNFβ基因多态性与EDSS评分无明显相关性。
