目的 探讨血必净与乌司他丁对内毒素(LPS)致绵羊高原多器官功能障碍综合征(H-MODS)的防治作用.方法 将25只绵羊从亚高原地区兰州(海拔1500 m)运输到高原地区桑科草原(海拔3200 m)后随机分为对照组(A组)、模型组(B组)、乌司他丁治疗组(C组)、血必净治疗组(D组).动物全麻后,以6 μg/kg LPS于30 min内静脉泵入建立H-MODS模型.在静脉泵入LPS后,C组、D组分别静脉滴注乌司他丁(30 000 U/kg)、血必净(2 mL/kg)注射液,均每天2次,连续3 d.A组和B组静脉滴注同剂量的生理盐水.于0、6、12、24、48和72 h测定不同时间点各组血清生化指标、血常规.结果 与B组比较,C组和D组动脉血氧饱和度下降幅度较小;治疗组AST、ALT、TBIL和Cr升高低于B组(P〈0.05);D组在个别时间点各项指标改善优于C组.B、C和D组绵羊的死亡率分别为71.4%、42.8%和28.6%.结论 乌司他丁和血必净均能降低 LPS诱导的H-MODS死亡率,对肺脏、肝脏和肾脏等多器官损伤具有一定的治疗作用,两者比较血必净治疗效果可能优于乌司他丁.
Objective To determine the therapeutic effect of utinastatin (UTI) and Xuebijing (XBJ) on multiple organ dysfunction syndrome at high altitude (H - MODS) in sheep model induced by lipopolysaccharide (LPS). Methods After 25 sheep were transported from LANZHOU at 1500 m altitude to SANKE grassland at 3200 m altitude, then randomly divided into 4 groups: normal control group (group A), H -MODS group (group B), UTI treatment group (group C), XBJ treatment group (group D). The anaesthetized sheep received intravenous infusion of LPS (6 Ixg/kg) to induced H - MODS in group B, group C and group D. The animals received injection of UTI (30 000 U/kg) for 3 days, twice daily in group C and XBJ (2 mL/kg)for 3 days twice daily in group D. Blood samples were taken for determination of serum alanine aminotransferase ( ALT), aspartate aminotransferase ( AST), creatinine (Cr), total bilirubin(TBIL) and blood routine at O(basement), 6, 12, 24, 48 and 72 h respectively. Results PaO2 decreased as early as at 6 h after injection of LPS. Compared with group B, PaO2 decreased less significantly in two treatment groups. AST, ALT, TBIL and Cr were significantly lower than those in group B ( P 〈 0.05), also there were obvious differences at some times between group C and group D. The animal mortality was 71.4%, 42.8% and 28.6% in group B, group C and group D respectively. Conclusion Application of UTI and XBJ could reduce the mortality of H - MODS animals induced by LPS. They have protective effects on lung, liver and kidney injuries in H - MODS animals. XBJ would have an advantage over UTI in protective effect.
