[摘要] 目的：观察氨茶碱对重症胎粪吸入新生兔的肿瘤坏死因子-α(TNF-α)和白细胞介素-8(IL-8)的影响。方法：将24只新生兔随机分成灌入胎粪后实施同步间歇指令通气(SIMV)应用氨茶碱组(氨茶碱组，n=6)、灌入胎粪后实施同步间歇指令通气组(氨茶碱对照组，n=6)、胎粪灌入后不予通气组(通气对照组，n=6)以及灌生理盐水不予通气组(空白组，n=6)。氨茶碱对照组和氨茶碱组给予机械通气6 h。氨茶碱组在胎粪灌注后0.5 h和2.5 h后静脉给予氨茶碱(2.0 mg/kg)，并用酶联免疫吸附试验(ELISA法)测定肺组织匀浆液及支气管肺泡灌洗液(BALF)中TNF-α和IL-8含量。结果：氨茶碱组和氨茶碱对照组比较肺组织匀浆和BALF中TNF-α和IL-8含量降低，差异均有统计学意义(均P<0.05)。与通气对照组、空白组比较，氨茶碱对照组、氨茶碱组的肺组织匀浆和BALF中TNF-α和IL-8含量明显升高，差异均有统计学意义(均P<0.05)。结论：氨茶碱可以降低新生兔重症胎粪吸入肺组织匀浆和BALF中TNF-α和IL-8的水平。

[Abstract] Objective: To observe effect Aminophylline on the levels of the tumor necrosis factor-α (TNF-α) and interleukin-8 (IL-8) of newborn rabbits with severe meconium aspiration. Methods: 24 newborn rabbits were randomly divided into four groups: implement synchronized intermittent mandatory ventilation (SIMV) after meconium instillation treated with Aminophylline (Aminophylline group, n=6), implement synchronized intermittent mandatory ventilation after meconium instillation (Aminophylline control group, n=6), no ventilation after meconium instillation (ventilation control group, n=6) and the saline irrigation with no ventilation group (control group, n=6). Aminophylline control group and Aminophylline group received 6 hours of mechanical ventilation. Rabbits intravenously received Aminophylline (2.0 mg/kg) at two doses 0.5 h and 2.5 h after meconium instillation in Aminophylline group ......
