1、江苏医药2013年9月第39卷第17期JiangsuMedJ,September2013,Vol39,No.17·论著·核素标记叶酸偶联白蛋白纳米微球对人卵巢癌细胞生长的影响唐秋莎陈道桢杨蕊臧嘉陈钰郭彩琴【摘要】目的观察核素标记叶酸靶向白蛋白纳米微球对人卵巢癌细胞生长的影响。方法将体外培养的SKOV3人卵巢癌细胞分为八组:阴性对照组(只加RPMI-1640培养液),单纯化疗组(叶酸偶联载药白蛋白磁性纳米微球,不加磁场),单纯放疗组[。铼(豫。Re)标记的叶酸偶联白蛋白磁性纳米微球,不加磁场],单纯热疗组(叶酸偶联白蛋白磁性纳米微球,加磁场)
2、,化疗联合放疗组(Re标记的叶酸偶联载药白蛋白磁性纳米微球,不加磁场),化疗联合热疗组(叶酸偶联载药白蛋白磁性纳米微球,加磁场),放疗联合热疗组(”Re标记的叶酸偶联白蛋白磁性纳米微球,加磁场)和热疗、化疗、放疗联合治疗组(联合治疗组,”Re标记的叶酸偶联载药白蛋白磁性纳米微球,加磁场)。48h后MTT方法测定各组细胞增殖率,流式细胞术测定细胞凋亡率。结果阴性对照组对卵巢癌细胞增殖的抑制作用弱于其他各组,联合治疗组强于其他各组(P3、二倍体凋亡峰;阴性对照组、单纯热疗组、化疗联合放疗组、化疗联合热疗组、放疗联合热疗组和联合治疗组的细胞凋亡率分别为0.08、7.56、17.14、21.64、33.94和57.16。结论磁感应热疗、化疗、核索靶向放疗的联合作用能有效抑制人卵巢癌细胞的生长。【关键词】顺铂;叶酸;白蛋白磁性纳米粒;。铼;卵巢癌【中图分类号】R737【文献标识码】A【文章编号I10253—3685(2013)17—1985—03E船ectof88Re-labeledfolatecouplingwithmagneticalbuminnanoparticlesong4、rowthofSK0V3ovariancancercellsinvitroⅣGusha,CHENDaozhen,YANGRui,eta1.DepartmentofPathologyandPhysiology,SchoolofMedicine,SoutheastUniversity,Naing210009,CJ删[Abstract]ObjectiveToinvestigatetheeffectofRe-labeledfolatecouplingwithmagneticalbuminnanoparticlesonthegrowthofSKOV35、ovariancancercellsinvitro.MethodsSKOV3cellsculturedinvitroweredividedinto8groupsofA(treatedwithRPMI-1640mediumasthecontro1),B(treatedwithfolatecouplingwithdrugloadedmagneticalbuminnanoparticles),C(treatedwithRe-labeledfolatecouplingwithmagneticalbuminnanoparticles),D(treat6、edwithfolatecouplingwithmagneticalbuminnanoparticlesinmagneticfield),E(treatedwithRe-labeledfolatecouplingwithdrug-loadedmagneticalbuminnanoparticles),F(treatedwithfolatecouplingwithdrug-loadedmagneticalbuminnanoparticlesinmagneticfield)。G(treatedwithReqabeledfolatecouplin7、gwithmagneticalbuminnanoparticlesinmagneticfield)andH(treatedwith。Reqabeledfolatecouplingwithdrug-loadedmagneticalbuminnanoparticlesinmagneticfield).Thecel1proliferationrateandcellapoptosisrateweremeasuredbyMTTassayandflowcytometryafter48hours,respectively.ResultsTheinhibi8、toryeffectonproliferationofSKOV3cellswasweakeringroupAthanthatintheothergroups,whichwasst
