摘要 目的探讨核因子-κB(nuclear factor-κB,NF-κB)在新生儿败血症中的表达及意义。方法分别于患儿入院时、入院后24、48h采用流式细胞仪检测外周血白细胞中NF-κB表达的百分数;根据血培养结果将患儿分为败血症组(26例)和非败血症组(31例),对照组为正常新生儿(20例)。结果败血症组外周血中NF-κB的表达明显高于非败血症组和对照组(P<0.0001),而非败血症组与对照组比较差异无统计学意义(P>0.05);败血症组NF-κB的表达水平在入院时明显高于入院后24h和48h(P均<0.0001),入院后24h与48h比较,NF-κB表达水平差异无显著性(P>0.05);非败血症组在入院时、入院后24、48h NF-κB的表达水平差异无显著性。结论NF-κB在新生儿败血症早期表达明显增加,NF-κB的活化可能是败血症炎症发生的分子机制之一。
