摘要
内毒素血症进展凶险,易诱发多脏器损伤,但目前尚无特异高效的治疗手段。清开灵注射液(Qingkailing Injection, QKLI)和生脉注射液(Shengmai Injection, SMI)临床上均具有抗炎、抗内毒素、保护脏器等多种功效。该研究拟采用角叉菜胶与内毒素先后注射入大鼠体内,建立内毒素血症大鼠模型,通过将不同剂量QKLI和SMI分别及联合腹腔注射到模型大鼠体内,然后检测大鼠体内白细胞数量、血小板数量、细胞因子含量、生化指标和主要脏器病理改变,从而探讨这2种中药注射剂联合应用对内毒素血症大鼠各项生理生化指标改变及急性脏器损伤的保护是否具有协同增效作用。结果显示,模型组大鼠出现了明显的内毒素血症症状,即白细胞减少,血小板下降,细胞因子(IL-6、TNF-α)含量升高,肝肾功能生化指标升高,肝脏、肾脏和肺部出现病理损害。QKLI单独用药能缓解内毒素血症模型的上述症状,在一定程度上减轻脏器损伤。SMI单独用药对内毒素血症并发的弥散性血管内凝血(disseminated intravascular coagulation, DIC)、细胞因子分泌等改善作用不显著,但对肺、肝和肾炎症病变程度有一定减轻作用。QKLI和SMI联合用药,对于提高内毒素血症大鼠外周血血小板数量,改善肝肾功能,降低炎性因子,保护肺、肝、肾等脏器结构等都有明显作用,并且在相同剂量药物情况下,QKLI和SMI联合用药改善作用比两药单独应用者强,显示一定的协同增效作用。
As a dangerous disease with rapid progression, endotoxemia is easy to induce the damage to multiple organs. However, its specific and efficient treatment methods are still lacking at present. Both Qingkailing Injection(QKLI) and Shengmai Injection(SMI) have been proved effective in anti-inflammation, anti-endotoxin and organ protection. In this study, carrageenan and endotoxin were injected successively into rats to establish an endotoxemia model. Different doses of QKLI and SMI were administered to the endotoxemia rats by intraperitoneal injection separately or in combination. Then the count of white blood cells, the number of platelets, the content of cytokines, biochemical indexes, organ coefficient and pathological changes of main organs in the rats were detected. The results showed that the rats in the model group had obvious symptoms of endotoxemia, i.e., leucopenia, thrombocytopenia, increase in cytokines(IL-6 and TNF-α) and biochemical indexes of liver and kidney function as well as pathological damage to liver, kidney and lung. QKLI alone can alleviate the above symptoms of endotoxemia and the organ injury. SMI alone is less effective in improving disseminated intravascular coagulation(DIC) and cytokine secretion complicated with endotoxemia, but capable of reducing the inflammation degree of the lung, liver and kidney. The combination of QKLI and SMI remarkably increased the number of platelets in the peripheral blood, improved the liver and kidney function and reduced inflammatory factors, with lung, liver, kidney and other organ structures protected well. Moreover, the improvement effect of the combination of QKLI and SMI was stronger than those of the two injections alone at fixed doses, indicative of a synergistic effect.
