目的:探讨三氧化二砷(As2 O3)联合紫杉醇(paclitaxel,PTX)对肺癌的治疗作用。方法噻唑蓝法(methyl thiazolyl tetrazolium,MTT)检测As2 O3联合PTX抑制肺癌A549细胞的增殖。采用激光共聚焦显微镜观察给药后对肺癌A549细胞的凋亡诱导作用。通过构建体外肿瘤球模型观察给药后对肿瘤球的生长抑制,模拟给药后药物在体内对肿瘤生长的抑制能力。建立肺癌裸鼠移植瘤模型,随机分为生理盐水组、As2 O3干预组、PTX干预组和联合干预组。每天分别用设定浓度的生理盐水、As2 O3、PTX、As2 O3+PTX对移植瘤小鼠腹腔内注射给药。观察给药后肿瘤大小的变化,计算抑瘤率。对肿瘤切片分别采用苏木精-伊红染色法(hematoxylin-eosin staining,HE)进行染色,考察As2 O3、PTX、As2 O3+PTX诱导体内肿瘤细胞凋亡的效果。结果肺癌A549细胞给药48 h后,生理盐水组、As2 O3干预组、PTX 干预组和联合干预组对肿瘤细胞的抑制率分别为(3.35±0.21)%、(47.55±2.25)%、(64.64±3.35)%和(84.58±3.76)%,各药物干预组与生理盐水组相比,差异的具有统计学意义(P<0.01)。生理盐水组诱导肿瘤细胞早期凋亡率为0.26%,As2 O3干预组为9.7%,PTX干预组为17.8%,联合干预组为42.5%,而与生理盐水组、As2 O3干预组和PTX干预组相比,联合干预组能够增加肿瘤细胞早期凋亡率,差异具有统计学意义(P<0.01)。肿瘤球给药7d后生理盐水组肿瘤球体积增大1.36倍,As2 O3干预组、PTX干预组和联合干预组分别使肿瘤体积减小到原体积的(77.35±2.31)%、(61.68±2.44)%和(44.85±3.34)%,差异均具有统计学意义(P<0.01)。荷瘤裸鼠治疗实验以生理盐水组为对照,As2O3干预组、PTX干预组和联合干预组对肿瘤生长的抑制率分别为(22.4±4.5)%、(39.5±6.2)%和(69.5±7.3)%,联合干预组与其他组间差异具有统计学意义(P<0.01)。结论As2 O3能够有效增强PTX 抑制A549细胞的增殖和裸鼠异位肿瘤的生长,As2 O3联合PTX 可能作为肺癌潜在有效的治疗手段。
