AIM:To investigate the therapeutic effects of a novel fluid resuscitation protocol (early fluid resuscitation plus 2％ hydrogen inhalation) on acute kidney injury during septic shock induced by lipopolysaccharide (LPS) in rats.METHODS:Male Wistar rats were randomly divided into 4 groups (15 rats per group):control group,septic shock group,septic shock with early fluid resuscitation group (fluid group) and septic shock with early fluid resuscitation plus 2％ hydrogen inhalation group (fluid + H2 group).The rats were ventilated,and a 2％ hydrogen mixture was used in fluid + H2 group.LPS (10 mg/kg) was administered to establish the septic shock model in rats and fluid resuscitation was performed in fluid group and fluid + H2 group.RESULTS:Fluid resuscitation with 2％ hydrogen inhalation decreased the levels of serum creatinine,blood urea nitrogen and neutrophil gelatinase-associated lipocalin.It also reduced oxidative stress injury and decreased renal tumor necrosis factor-α and interleukin-6 levels compared with fluid resuscitation alone.CONCLUSION:Early fluid resuscitation plus 2％ hydrogen inhalation provided more protection against acute kidney injury during septic shock.%目的:评价联合2％氢气吸入的液体复苏方案对脂多糖(LPS)诱导的脓毒性休克大鼠肾脏的治疗效果.方法:60只Wistar大鼠随机分成4组(每组15只):正常对照(control)组,脓毒性休克(shock)组,脓毒性休克+液体复苏组(fluid组),脓毒性休克+2％氢气吸入联合液体复苏组(fluid+ H2组).大鼠麻醉后予呼吸机辅助通气,fluid+ H2组给予2％氢气空气混合气,其余3组给予单纯空气吸入.10 mg/kgLPS静脉注射,建立脓毒性休克模型,control组给予等量生理盐水静脉注射.Fluid组和fluid+ H2组给予相同液体复苏方案,维持平均动脉压于正常水平.4h后,大鼠经腹主动脉放血处死,留取血液及肾脏标本.结果:联合2％氢气吸入的液体复苏方案与单纯液体复苏比较,血肌酐、尿素氮、中性粒细胞明胶酶相关脂质运载蛋白及肾脏组织TNF-α、IL-6水平明显降低,氧化应激损伤程度明显减轻.结论:联合2％氢气吸入的液体复苏方案更能减轻脓毒症所致急性肾损伤.
