摘要
目的:研究肿瘤坏死因子βTNFβ基因多态性与吉兰-巴雷综合征( GBS )的两种主要亚型-急性炎症性脱髓鞘性多发性神经病(AIDP)和急性运动性轴索型神经病(AMAN)的易感性和预后的关系。方法对我院在2008至2011年收治的吉兰-巴雷综合征患者进行电生理标准分型,在疾病高峰期和发病1年后随访时进行Hughes神经功能评分;采用聚合酶链式反应-限制性片段长度多态性( PCR-RFLP )技术对41例AIDP患者、52例AMAN患者和98名健康人进行TNFβ基因多态性分析。结果 AIDP组TNFβ基因型分布与对照组没有差别,TNFβG等位基因频率明显高于对照组(37.8%,25%);AMAN组TNFβ基因型分布与对照组相比有差别,TNFβG等位基因频率明显高于对照组(40.4%,25%),P<0.05;GBS重症型患者(Hughes评分4~6分)TNFβG等位基因频率明显高于对照组(40.6%,25%),P<0.05。 GBS预后较差患者(Hughes评分>2分)TNFβG等位基因频率明显高于对照组(47.5%,25%),P<0.05。结论 TNFβG等位基因与GBS两种亚型的易患性有关,携带有TNFβG等位基因患者更倾向有较严重的疾病病程且预后较差。
Objective To study the relations between the susceptibility to AIDP and AMAN , two subsets of GBS, and the frequencies of TNFβgene polymorpsim; Methods The patients with GBS were recruited between 2008 and 2011 and retrospectively reviewed .The gene polymorphism of TNFβdetected by means of polymerase chain reaction (PCR) with restriction fragment length polymorphisms (RFLP) techniques.Results TNFβG frequency increases significantly in AIDP group, AMAN group,severe group and poor outcome group than controls (37.8%, 40.4%, 40.6%, 47.5%vs.25%) .Conclusion AMAN and AIDP are the main subtypes of GBS in northeastern China.The two main subsets of GBS susceptibility is associated with TNFβG allele,and patients with the G allele of TNFβare likely to have more severe pathogenesis and poor outcomes .
