肺瘤平膏及其拆方对DC刺激LPAK抗肿瘤活性的影响

Influence on DC Stimulating LPAK Anti-tumor Activity by Feiliuping Extract and Its Decomposed Recipe

  • 摘要: 目的 比较不同中药含药血清对树突状细胞(dendritic cell,DC)刺激LPAK抗肿瘤活性,为指导临床用药提供初步的实验依据。方法从健康人外周血中分离获得PBMC,采用多种细胞因子诱导,获取DC及LPAK,采用中性红摄入比色法检测肺瘤平膏及其拆方含药血清干预DC-LPAK细胞杀伤肿瘤细胞活性的不同。结果LPAK∶Tumor (L∶T)为10∶1或5∶1组时,各中药组DC诱导的LPAK细胞,杀伤活性明显高于对照组(P<0.05)。组内杀伤活性比较,即L∶T(10∶1)与L∶T(5∶1)比较,解毒组、空白DC对照组、T+LPAK组,P<0.05,余各组比较,P>0.05;肺瘤平膏组、益气组、活血组在L∶T为5∶1与10∶1时,诱导LPAK的杀伤活性基本相同。结论肺瘤平膏、活血药、益气药可不同程度增强DC-LPAK杀伤肿瘤细胞的作用,而解毒药则对其有抑制作用。

     

    Abstract: Objective To Discuss the different action of DC-LARK under different Traditional Chinese Medicine,and provide an initial experimental basis on clinical medication. Methods The inducing cultural system was established to induce and differentiate mature dendritic cells from human peripheral blood mononuclear cells (PBMC),PBMC were separated from peripheral blood of healthy people.The cytokines were used jointly to induce and obtain the mature dendritic cells and lymphokine and phytohaemagglutinin activated killer (LPAK).The different influence of Feiliuping Extract and its decomposed recipe on DC stimulating LPAK anti-tumor acitivity was compared. Results The killing activity was significantly higher than comparison group when LPAK∶Tumor (L∶T) equaled 10∶1 or 5∶1(P<0.05). Feiliuping Extract group,YiQi group and Huoxue group had higher effects than JieDu group. Comparing within groups,i.e.comparing L∶T(10∶1) with L∶T(5∶1),JieDu Group,blank DC group,T+LPAK group,P<0.05.The other groups,P>0.05.Feiliuping Extract group,YiQi Group & HuoXue Group has similar effects on stimulating LPAK′s killing activity,while L∶T eaquals 10∶1 or 5∶1. Conclusion Feiliuping Extract,HuoXue herbs & YiQi herbs can strengthen the action of DC stimulating DC-LPAK of killing tumor cells to different extent,however,JieDu herbs has little inhibition action.
