    摘要:

    目的 探讨血必净(XBJ)对多脏器功能障碍综合征(MODS)炎性因子的影响。方法 将90只Wistar大鼠随机分为对照组、模型组与XBJ组。尾静脉注射内毒素(LPS)(15 μg / kg)建立MODS模型。观察各组的体征表现,用ELISA方法检测TNF-α、IL-1α、IL-4 和 IL-10的表达水平。结果 ① 对照组、模型组和XBJ组的死亡率分别为:0、37%和20%;② 与模型组相比XBJ可促进了TNF-α的表达,同时抑制IL-1α的表达,且TNF-α和IL-1α高表达集中在6h~24h;③ 模型组与XBJ组IL-4的表达量在6h~12h与对照组相比明显升高(P<0.05);模型组IL-10在6h~48h与对照组相比明显升高(P<0.05);XBJ组IL-10的表达水平在6h与对照组相比明显升高(P<0.05)。结论 XBJ能降低LPS介导的大鼠MODS的死亡率,可同时促进TNF-α释放和抑制IL-1α、IL-4和IL-10释放,有效改善MODS的反应状态。

    Abstract:

    Objective To evaluate the influence of Xuebijing (XBJ) by inflammation cytokines of multiple organ dysfunction syndrome (MODS). Methods 90 rats were randomly separated into 3 groups, the control group and XBJ group were infused 15 μg / kg LPS in vena caudalis, Then the physical sign appearance was observed and collection the serum to determine the expression concentration of TNF-α、IL-1α、IL-4 and IL-10 by ELISA in each group at different times. Results ① The death rate of rats were the percent of 0, 37, and 20 in the control group,model group and XBJ group, respectively. ② The XBJ enhance the increased amplitude of TNF-α and deduce the increased amplitude of IL-1α by compared with model group, the expression concentration peak of TNF-α and IL-1α is 6h~24h. ③ The expression concentration of IL-4 in model group and XBJ group in model group has significant ascendant compared with control group at 6h~48h; XBJ group has significant have significant ascendant compared with control group at 6h~12h (p<0.05).The expression concentration of IL-10 ascendant compared with control group at 6h (p<0.05). Conclusion The results demonstrated that XBJ could degrade the death rate of MODS induced by LPS,and it could reduce the increased amplitude of TNF-α, whereas enhance the increased amplitude of the serum IL-1α,IL-4 and IL-10, it could also prevent those rats from changing into MODS efficiently.
