摘要
目的探讨肺复张方法和潮气量对急性呼吸窘迫综合征(ARDS)家兔肺泡灌洗液(BALF)中TNF-α、IL-8及IL-10的影响。方法建立ARDS家兔模型,用ELISA法检测不同组别家兔BALF中的TNF-α、IL-8及IL-10,并比较检测结果。结果呼气末正压(PEEP)递增法组BALF中的TNF-α、IL-8显著低于控制性肺膨胀(SI)组及ARDS组,而IL-10显著高于SI组及ARDS组(均P<0.01)。不同潮气量中,小潮气量组BALF中的TNF-α、IL-8显著低于其他潮气量组,而IL-10显著高于其他潮气量组(均P<0.01)。PEEP递增法组中,小潮气量组BALF中的TNF-α、IL-8显著低于其他潮气量组,而IL-10显著高于其他潮气量组(均P<0.01)。结论 PEEP递增法+小潮气量可抑制ARDS家兔BALF中的TNF-α、IL-8的释放,增加IL-10的释放,减轻肺内炎症反应。
Objective To determine changes and significance of different lung recruitment and tidal volume on TNF-α,IL-8 and IL-10 in bronchoalveolar lavage fluids(BALF) of rabbits with acute respiratory distress syndrome(ARDS).Methods After ARDS rabbit model was developed.TNF-α,IL-8 and IL-10 in different groups of rabbits BALF were measured by ELISA and comparison of determined results was performed.Results TNF-α,IL-8 in positive end-expiratory pressure(PEEP) increase group were significantly lower than those in the suatained inflation(SI) group and the ARDS group,but IL-10 was obviously higher than that in the SI group and the ARDS group(P0.01).In different tidal volume groups,TNF-α,IL-8 of BALF in small tidal volume group was significantly lower than those in the other groups,but IL-10 was obviously higher than that in the other tidal volume groups(P0.01).In PEEP increase groups,TNF-α,IL-8 of BALF in small tidal volume group were significantly lower than those in the other tidal volume groups,IL-10 was obviously higher than that in the other tidal volume groups(P0.01).Conclusion PEEP increase and small tidal volume inhibit the release of TNF-α,IL-8 in BALF of ARDS rabbits,increase the release of IL-10,and release inflammatory response within the lungs.
