摘 要:目的:观察异丙酚对油酸性急性肺损伤(ALI)兔血清TNFα-、IL-1β水平的影响,探讨异丙酚治疗油酸型ALI的可能机制。方法:健康日本大耳白兔24只,随机分成对照组(Ⅰ组)、急性肺损伤组(Ⅱ组)和异丙酚治疗组(Ⅲ组)。Ⅱ、Ⅲ组兔静脉注射油酸0.08 mL/kg,复制日本大耳白兔ALI模型。建模成功后Ⅲ组静脉注射异丙酚8 mg.kg-1.h-1,Ⅰ组和Ⅱ组静脉注射生理盐水0.8 mL.kg-1.h-1至实验结束。各组大耳白兔分别在输入异丙酚或生理盐水前(T0)和给药后1 h(T1)、2 h(T2)、3 h(T3)、4 h(T4)采集动脉血用ELISA法检测血清TNF-α、IL-1β,同时进行血气分析,计算PaO2/FiO2结果:Ⅰ组血清中TNF-α、IL-1β浓度各时点无明显变化(P>0.05)。Ⅱ组TNFα-浓度在T1开始升高,T2达高峰,T3、T4有下降但仍高于T0(P<0.05),与Ⅰ组相应时点比较升高明显(P<0.05)。Ⅲ组各时点TNF-α浓度升高明显低于Ⅱ组(P<0.05)。与T0比较,Ⅱ组血清IL-1β浓度在T1开始升高,T4达高峰(P<0.05),各时点浓度均明显高于Ⅰ组(P<0.05),Ⅲ组IL-1β浓度升高程度低于Ⅱ组(P<0.05)。Ⅰ组各时点氧合指数无明显变化。Ⅱ、Ⅲ组随着时间延长氧合指数逐渐下降,明显低于Ⅰ组(P<0.05),Ⅲ组氧合指数下降幅度较Ⅱ组低(P<0.05)。结论:异丙酚能通过降低油酸性ALI兔血清TNF-α、IL-1β的释放,提高油酸性ALI后氧合指数,对兔油酸性ALI起到一定的保护效果。AIM: To observe the effects of propofol on serum TNF-α,IL-1β in rabbit with acute lung injury(ALI) induced by oleic acid(OA) and explore its possible protective mechanism and provide evidence for the choice of anesthesia drug in clinical anesthesia.METHODS: Twenty four health Japanese white rabbits were randomly divided into three groups(n=8): control group(group Ⅰ),model group(groupⅡ) and propofol treatment group(group Ⅲ).The rabbits in group Ⅱ and Ⅲ were injected oleic acid(OA)(0.08 mL/kg) by marginal veins of ear to establish ALI models.The rabbits of group Ⅲ were injected propofol(8 mg·kg-1·h-1) with pump,while group Ⅰ and group Ⅱ were injected normal saline(0.8 mL·kg-1·h-1) to end of the experiment after establishing the ALI models successfully.The concentration of TNF-α and interleukin-1β in serum were detected by ELISA at the points of propofol or normal saline infusion(T0),1 h after administration(T1),2 h after administration(T2),3 h after administration(T3),4 h after administration(T4),and blood gas analysis of them had been performed to calculate the PaO2/FiO2 Ratio.RESULTS:The concentrations of TNF-α and interleukin-1β in serum in group Ⅰ had no difference at different points(P0.05).The concentration of TNF-α began to increase at T1,reached to peak at T2 and decreased at T3,T4,but still higher than those of T0(P0.05).The concentrations of TNF-α in group Ⅱ increased more obviously than those of group Ⅰ(P0.05) and were lower in group Ⅲ than those of group Ⅱ(P0.05) at the corresponding time point.Compared with T0 the concentrations of interleukin-1β in groupⅠbegan to increase at T1,reached to the peak at T4(P0.05) and were higher than those of group Ⅰ at the corresponding time points(P0.05),increased lowerly in group Ⅲ than those of group Ⅱ(P0.05).The oxygenation index at different time points had no significant change in group Ⅰ,decreased gradually after establi
