2、-2mRNA表达情况。结果与阴性对照组比较,金龙胶囊治疗组(B、D组)抑瘤率分别为26.94%、51.61%,联合用药组(D组)效果最佳。治疗组微血管密度分别为18.83±0.75、14.17土0.75,联合用药组最为显著,而单药顺铂组与对照组在抑瘤率和微血管密度表达上均无差异(P>0.05)。金龙胶囊治疗组(B、D组)Bc1.2mRNA表达较对照组有显著差异(P<0.001),但两组之间无差异(P:0.369);四组之间在VEGFmRNA表达上无明显差异(P>0.05)。结论金龙胶囊对荷A549裸鼠移植瘤有抑制作用,联合顺铂用药有显
3、著协同作用,其作用机制可能与抑制肿瘤微血管形成、诱导细胞凋亡增加有关。关键词:肺癌;金龙胶囊;顺铂;血管内皮生长因子;微血管密度;裸鼠移植瘤doi:10.3969/j.issn.1003.8914.2014.07.017文章编号:1003—8914(2014)-07-1387-04EfectofJinLongCapsuleCombinedWithCisplatinonTumorGrowthofHumanLungAdenocarcinoma(A549)XenograftsinNudeMiceDaiMingYangQingrongZhon
