摘要 目的 探讨早产儿脑损伤、母亲的绒毛膜羊膜炎与脐血白细胞介素 6 (IL 6 )水平三者间的相互关系 ,了解临床检测脐血IL 6水平的意义 ,为临床预防和诊断早产儿脑损伤提供理论依据。方法 用酶联免疫吸附试验检测 31例早产儿脐血中IL 6水平 ,用头颅超声或CT诊断早产儿脑损伤 ,对母亲的胎膜组织行病理检查。结果  (1)母亲有绒毛膜羊膜炎组早产儿脑损伤发生的频率为75 % ,较无绒毛膜羊膜炎组的脑损伤发生频率 (32 % )显著增高 ;有脑损伤的早产儿脐血IL 6水平中位数为 1 7μg/L ,范围为 0 1~ 14 3μg/L ,明显高于无脑损伤组 (中位数为 0 8μg/L ,范围为 0 3~ 3 7μg/L) ;脑损伤伴母亲感染组脐血IL 6水平中位数为 2 3μg/L ,范围为 1 2~ 14 3μg/L ,较不伴母亲感染组(中位数为 1 2 μg/L ,范围为 0 1~ 2 4μg/L)明显升高。 (2 )以头颅影像学结果为依据 ,脐血中IL 6水平≥ 1 2 μg/L可作为诊断与感染相关的早产儿脑损伤的标准 ,其敏感度为 80 % ,特异度为 75 %。结论 母亲的绒毛膜羊膜炎与早产儿脑损伤的发生有密切关系。脐血IL 6水平不仅可以反映母亲的感染情况 ,还可预示早产儿有无脑损伤 ,故临床检测脐血中的IL 6有临床实用价值。 Objectives To examine the relationship among neonatal brain damage, maternal chorioamnionitis and umbilical cord serum interleukin 6(IL 6) concentration, to evaluate the clinical significance of examining umbilical cord serum IL 6 concentration, and to provide a new method for preventing and diagnosing brain damage in the preterm neonates Methods This study involved 31 preterms (1) The umbilical cord serum IL 6 concentration of neonates was detected by enzyme linked immunosorbent assay; (2) Matern...
