目的 观察消癌平联合奥曲肽对鼠H22移植瘤的抑瘤作用,寻找最佳抑瘤浓度,并初步探讨其可能的作用机制.方法 建立小鼠皮下H22移植瘤模型,成瘤后将实验动物分为正常组,模型对照组,消癌平低、中、高剂量组,奥曲肽组,消癌平低、中、高剂量分别联合奥曲肽组,计算各瘤体体积,绘制肿瘤生长曲线,腹腔注射给药14d,计算抑瘤率,光镜下观察组织病理变化;流式细胞仪测外周血中CD3+ NK1.1-T细胞,CD3-NK1.1+NK细胞,CD3+ NK1.1+NKT细胞的比例.结果 与模型对照组比较,各用药组对H22肝癌的生长均有一定的抑制作用,联合用药组的抑瘤作用优于单药组,以高剂量消癌平联合奥曲肽的作用最好.荷瘤模型组与正常对照组比较,T细胞、NK细胞和NKT细胞比例明显降低(P<0.05);药物干预后各组T细胞、NK细胞和NKT细胞比例均有一定程度的增强,以高剂量消癌平联合奥曲肽组增强最为明显.且联合用药组与奥曲肽组、相应剂量的消癌平单药组相比,T细胞、NK细胞和NKT细胞比例明显升高(P<0.05).结论 高剂量消癌平联合奥曲肽为抑瘤的最佳药效浓度,其抑制肿瘤生长的作用可能与改善荷瘤小鼠机体的免疫状态,增强机体的抗肿瘤能力有关.

Objective To observe the inhibitory effect of xiaoaiping injection and octreotide on H22 tumor-bearing mice and find the best drug concentration,then to explore its mechanism.Methods Establish a mouse H22 subcutaneous tumor model.After tumor the experiment animals were divided into normal control group,model group,Xiaoaiping low,medium and high dose group,octreotide group,and the group of XAP low,medium and high dose groups were combined with OCT.Calculate the tumor's volume and draw the tumor growth curve.Intraperitoneal injection for 14 days,Inhibitory rate was calculated; To observe its pathological changes by light microscope; The ratio.of CD3 + NK1.1-T cells,CD3-NK1.1 + NKcells,CD3 + NK1.1 + NK-Tcells in peripheral blood were measured by flow cytometry.Results Compared with the control group,H22 liver cancer in different treatment group had a certain inhibition effect on growth,The inhibitory effect of the combination group was better than single-agent group,High-dose Xiaoaiping + octreotide was best,Tumor model group compared with normal control group,The ratio of T cells,NK cells and NKT cells was significantly lower(P <0.05) ; T cells,NK cells and NKT cells after treatment in each group had some enhancement,High-dose Xiaoaiping + octreotide was the most obvious,the ratio of T cells,NK cells and NKT cells of the combination group was significantly more than the single-drug group and the same concentration of octreotide monotherapy Xiaoaiping group(P < 0.05).Conclusion High-dose Xiaoaiping + octreotide is the best drug for the inhibitory drug concentration.The inhibition of tumor growth may pass to improve the tumorbearing mice with immune status and enhance the body's anti-tumor capacity.
