摘要: 目的: 研究NF-κB信号转导通路与复发性口腔溃疡(RAU)易感性的相关性。方法: 采用ELISA方法检测124例RAU患者和133例健康对照者中NFκBp50、NFκBp65、IκBα、IKK的血清含量,则用限制性片段长度多态性-聚合酶链式反应(RFLP-PCR)进行NFκB-94 ins/del ATTG位点的基因多态性分析,用比值比(OR)和95%可信区间(95%CI)估计相对危险度,采用SPSS 20.0软件包对数据进行统计学分析。结果: RAU组患者血清NFκBp50、NFκBp65、IKK 水平均显著低于正常对照组(P<0.05),RAU组患者血清IκBα水平均显著高于正常对照组(P<0.05)。NFκB-94 ins/del ATTG位点在基因型频率与等位基因频率的分布上,病例组与正常对照组之间均有显著差异(P<0.05)。NFκB-94 ins/del ATTG位点基因型ID(OR=3.073,95%CI=1.557-6.067)与DD(OR=4.851,95%CI=2.264-10.393)为高风险基因型,D等位基因为高风险等位基因(OR=2.079,95%CI=1.462-2.957)。结论: NF-κB信号转导通路与复发性口腔溃疡有一定关系。NFκB-94 ins/del ATTG位点是RAU患者的易感基因位点。NFκB-94 ins/del ATTG位点携带D等位基因,患RAU的风险性是携带I等位基因的2.079倍。

Abstract: PURPOSE: To explore the possible relationship between recurrent aphthous ulcer (RAU) and nuclear factor-κB signaling pathway. METHODS: A total of 124 RAU patients were recruited for this study. The control group consisted of 133 healthy subjects. Serum NFκBp50, NFκBp65, IκBα and IKK concentration were detected by ELISA.NFκB-94 ins/del ATTG sites were detected by restriction fragment length polymorphism-polymerase chain reaction (RFLP-PCR). Relative risk ratios were estimated by odds ratios (OR) and 95% confidence interval (95%CI). Statistical analysis was performed using SPSS 20.0 software package. RESULTS: Serum NFκBp50, NFκBp65 and IKK levels in RAU patients were significantly lower than those of the controls (P<0.05). Serum IκBα level in RAU patients was significantly higher than those of the controls (P<0.05). Significant differences were found in the genotype frequencies or allele frequencies of NFκB-94 ins/del ATTG sites between RAU patients and controls (P<0.05). ID genotype(OR=3.073,95%CI=1.557-6.067), DD genotype (OR=4.851,95%CI=2.264-10.393), and D allele (OR=2.079,95%CI=1.462-2.957) at NFκB-94 ins/del ATTG site exhibited high risks of RAU. CONCLUSIONS: NF kappa B signaling pathway is associated with RAU.NFκB-94 ins/del ATTG sites are associated with higher risk of RAU. NFκB-94 ins/del ATTG D allele may serve as genetic determinants for RAU.
