摘要 目的探讨血乳酸和肿瘤坏死因子-α(TNF-α)在早产儿坏死性小肠结肠炎(NEC)中的变化及临床意义。方法选取2008—2011年我院收治的Ⅱ~Ⅲ期NEC早产儿为观察组,并根据临床评价分期,按1:1比例选择同期非NEC早产儿为对照组,观察组在确诊NEC后即刻采血,对照组选择相同时间点取血。分别用Vitros250干化学分析仪测定血乳酸浓度,ELISA法测定血浆TNF-α浓度。结果 NECⅡ期患儿(18例)血乳酸和TNF-α水平分别为(6.4±0.7)mmol/L,(34.1±4.6)ng/dl;NECⅢ期患儿(9例)血乳酸和TNF-α水平分别为(8.5±0.6)mmol/L,(39.6±2.4)ng/dl;对照组分别为(1.6±0.4)mmol/L,(17.5±5.3)ng/dl。NEC患儿血乳酸和TNF-α水平显著高于对照组,Ⅲ期患儿高于Ⅱ期患儿,差异有统计学意义(P<0.05);血乳酸和TNF-α含量与NEC分期均呈正相关关系(r分别为0.71、0.51,P<0.01)。结论 NEC患儿血乳酸和TNF-α浓度明显高于对照组,与临床分期基本一致,检测血浆中乳酸和TNF-α水平,对于疾病的早期诊断、病情程度的判断及疗效的评价有一定临床意义。
