[摘要] 目的 探讨脐带血白细胞介素1受体相关激酶-M(interleukin-1 receptor-associatd kinase-M,IRAK-M)基因多态性与新生儿早产及主要并发症的关系。 方法 选择 2015 年1月~2017 年 12 月本院出生的≤34 周的早产儿 200例为研究对象,母亲分娩时取脐带血,测定 IRAK-M基因位点多态性;记录早产儿的临床资料,分析 IRAK-M基因多态性与早产儿主要并发症的关系。 结果 200例早产儿中主要住院情况有创机械通气治疗、吸氧治疗、肺表面活性物质应用、低血压或休克、败血症、发生呼吸暂停。早产儿的IRAK1主要基因分型为 rs3027898 (CC、AC 或AA3 种基因型)和rs1059703(CC、CT或TT3种基因型)。rs3027898(AC+AA)和rs1059703(CT+TT)增加了RDS的发生率,rs3027898(AC+AA)增加了ROP发生率,差异有统计学意义(P<0.05)。 结论 测定脐带血IRAK-M基因多态性可以影响早产儿的主要并发症,有助于评估患儿预后。

[Abstract] Objective To investigate the relationship between polymorphism of interleukin-1 receptor-associative kinase-M(IRAK-M) gene and premature delivery as well as major complications in neonates. Methods A total of 200 premature infants(≤34 weeks) born in our hospital from January 2015 to December 2017 were enrolled. The cord blood was taken when the mother gave birth. And the IRAK-M locus polymorphism was determined. The clinical data of premature infants were recorded and the relationship between IRAK-M gene polymorphism and major complications in preterm infants was analyzed. Results The main hospitalizations in 200 preterm infants were invasive mechanical ventilation, oxygen therapy, pulmonary surfactant application, hypotension or shock, sepsis, and apnea. The main genotype of IRAK1 in premature infants is rs3027898(CC, AC or AA genotypes) and rs1059703(CC, CT or TT3 genotypes). rs3027898 (AC+AA) and rs1059703 (CT+TT) increased the incidence of RDS, and rs3027898 (AC AA) increased the incidence of ROP, and the difference was statistically significant(P<0.05). Conclusion Measuring IRAK-M gene polymorphism in cord blood can affect the main complications of premature infants and help to assess the prognosis of children.

白細胞介素1受体相关激酶(interleukin-1 receptor-associatd kinase-M,IRAK-M)是近年来发现的参与机体先天性免疫反应过程的关键丝/苏氨酸激酶,IRAK家族通过一系列的级联反应,参与调解TOLL样受体(toll like receptor,TLR)L/IL-1受体家族信号转导通路,识别病原相关分子模式,能在IL-1诱导下和 IL-1R 相结合[1]。IRAK-M 还调节获得性免疫的发生和类型,从而构成机体内的第一道免疫防线,可参与调节多种炎性疾病的发生发展[2,3]。但目前针对白细胞介素1受体相关激酶-M(IRAK-M)基因多态性与早产儿及主要并发症的关系研究较少。本研究通过检测临床孕妇脐带血IRAK-M+22148G>A多态位点的基因型,进一步探讨IRAK-M基因多态性与新生儿早产及并发症的关系,为新生儿并发症的早期诊断和预后判定提供依据,为精准医疗提供临床证据。
