          摘   要  目的  观察内源性代谢物中康酸联合乳酸钠林格注射液(LR)延长高原条件下失血性休克大鼠黄金救治时间窗的作用及
          复苏效果。方法  将大鼠分为休克组、LR组和5、20、50 mg/kg中康酸+LR组,每组20只,以考察加用中康酸对黄金救治时间窗的
          影响。各组大鼠以低压缺氧舱饲养+脾动脉离断的方式构建高原条件下非控制性失血性休克模型后,休克组大鼠不进行复苏,LR
          组和中康酸+LR组大鼠以LR或中康酸联合LR进行低压复苏,观察各组大鼠的血压控制情况、输液量、失血率和存活情况。进一
          步将大鼠分为正常组、休克组和中康酸(50 mg/kg)+LR组,每组10只或20只,以考察加用中康酸延长黄金救治时间窗后的复苏效
          果。除正常组外,其余各组同法构建高原条件下非控制性失血性休克模型。休克组大鼠不进行复苏;中康酸+LR组大鼠以中康酸
          联合LR进行低压复苏至3 h,结扎脾动脉止血,记录输液量和失血率,随后按2倍失血量进行LR复苏。检测中康酸+LR组大鼠不
          同时间点的血气指标,观察各组大鼠的存活情况、舌下微循环灌注功能相关指标、肝/肾血流量、重要器官功能相关指标和肺/脑含
          水量。结果  单纯LR复苏能使休克大鼠平均动脉压(MAP)在50~60 mmHg内维持约1 h,中康酸与LR联合应用可使其MAP在
          50~60 mmHg稳定维持3 h以上,且50 mg/kg中康酸+LR组大鼠的输液量、失血率均较LR组显著减少(P<0.05)。LR组大鼠低压
          维持至1 h后,存活率为52.94%,无大鼠存活超过2 h;5、20、50 mg/kg中康酸+LR组大鼠低压维持至1 h后,存活率均超过80%;20、
          50 mg/kg 中康酸+LR 组大鼠低压维持至 3 h 后,存活率仍超过 70%。经中康酸联合 LR 彻底复苏后,该组大鼠的 72 h 存活率为
          43.75%,其血气指标均较休克期末显著改善(P<0.05)。与休克组比较,中康酸+LR组大鼠彻底复苏后的舌下微循环相关指标和
          肝、肾血流量均显著恢复(P<0.05),心、肝、肾功能相关指标和肺含水量均显著降低(P<0.05)。结论  中康酸联合LR可显著延长
          高原条件下失血性休克大鼠黄金救治时间窗,改善其血气指标、舌下微血管循环灌注及肝/肾血流量,减轻重要器官功能损伤和肺
          水肿,提高休克大鼠的存活率。

          Effect  of  mesaconate  combined  with  LR  on  prolonging  the  golden  treatment  time  window  and  its
          resuscitation efficacy for hemorrhagic shock rats under high-altitude conditions

          ABSTRACT    OBJECTIVE  To  observe  the  effects  of  endogenous  metabolite  mesaconate  combined  with  Sodium  lactate  Ringer’s
          injection (LR) on prolonging the golden treatment time window and its resuscitation efficacy in rats with hemorrhagic shock under
          high-altitude  conditions.  METHODS  Rats  were  divided  into  the  shock  group,  LR  group,  and  5,  20,  50  mg/kg  mesaconate+LR
          groups, with 20 rats in each group, to investigate the effect of additional use of mesaconate on the golden treatment time window.
          After establishing a model of uncontrolled hemorrhagic shock under high-altitude conditions in all groups by housing in a hypobaric
          hypoxia  chamber  combined  with  splenic  artery  transection,  rats  in  the  shock  group  received  no  resuscitation,  while  rats  in  the  LR
          group  and  mesaconate+LR  groups  underwent  low-pressure  resuscitation  with  LR  or  mesaconate  combined  with  LR.  Blood  pressure
          control, fluid infusion volume, blood loss rate and survival status were observed in each group. Rats were further divided into the
          normal group, shock group and mesaconate (50 mg/kg)+LR group, with 10 or 20 rats in each group, to evaluate the resuscitation
          effects after extending the golden treatment time window by additionally using mesaconate. Except for the normal group, the other
                                                              groups  underwent  the  same  procedure  to  establish  an
