摘　　要：[目的]观察小柴胡汤联合环磷酰胺对腹水瘤细胞株(EAC)肝癌小鼠体重、肿瘤间质血管生成影响。[方法]使用随机平行对照方法,将40只昆明小鼠,采用完全随机化分组方法分为模型组、中药组、西药组、联合组,每组10只。各组皮下注射浓度为2.0×106/ml的EAC肝癌小鼠细胞株0.2ml/只造模,分别给予小柴胡汤、环磷酰胺、小柴胡汤+环磷酰胺灌胃。免疫组化法检测血管内皮生长因子(VEGF)表达、光镜下观察形态学改变,透射电镜观察肿瘤组织血管生成。[结果]中药组、西药组、联合组VEGF阳性表达,瘤组织内的VEGF蛋白表达阳性率和平均染色强度均低于模型组(P<0.01),联合组最明显。光镜下显示:中药组、西药组、联合组肿瘤间质毛细血管数量均减少,联合组最为明显,中药组次之。电镜下显示:中药组、联合组都可以破坏肿瘤组织内新生毛细血管结构,联合组破坏最严重。[结论]小柴胡汤联合环磷酰胺可降低EAC肝癌小鼠瘤组织中VEGF蛋白表达;、抑制肿瘤间质血管生长。[ Objective ] Discuss the anti - cancer function and mechanism of small entrapement soup and western chemotherapeutics cyclophosphamide on EAC mice affected liver cancer. [Methods] 40 mice from Kuming, hypodermic injection of 2.0 x 106/mL EAC cancer liver mice cell line 0.2mL/, treat it with en- trapement soup, cyclophosphamide, entrapement soup and cyclophosphamide separately, Immune group test the law endothelium growth factor express. The morphological changes were observed under the light micro- scope. Then find the situation of hepatumor cells with transmission electron microscope. [ Results ] lmmunohistochemistry showed, XiaoChaiHu group, CTX group, XiaoChaiHu ＋ CTX group VEGF po - sitive expression, XiaoChaiHu group, CTX group, XiaoChaiHu ＋ CTX group VEGF po - sitive expression rate and average strength in dyeing were lower than the control group, XiaoChaiHu ＋ CTX group to reduce the most obvious. Under light microscope, XiaoChaiHu group, CTX group, XiaoChaiHu ＋ CTX group can reduce the quantity of tumor stromal capillaries in newborn, XiaoChaiHu ＋ CTX group is the most obvious. XiaoChaiHu group is the second. Under electron microscope, XiaoChaiHu group, CTX group, XiaoChaiHu ＋ CTX group can damage the structure of tumor stromal capillaries in newborn , xeht ＋ CTX group to damage the most obvious. [ Conclusions ] XiaoChaiHu Decoction combined with Cyclophosphamide may reduce liver cancer in mice EAC tumor VEGF protein expression and restrain the grown of the Tumor interstitial vascularity.
