2、1)、PC2组(紫杉醇001ttg/ml+llN铂0.01~g/m1)。无菌环境下实施4Gy照射。采用MTT法观察SGC细胞增殖抑制率;以流式细胞技术检测细胞凋亡及周期变化。结果PC1组和PC2组胃癌SGC细胞抑制率分别为(76.6±7.7)和(68.3士2.6),明显高于P1组的(46.74-4.5)、P2组的(39.2士5.3)、C1组的(41.4±0.2)和C2组的(25.6±1.3)(P3、离体胃癌细胞放疗有明显增敏作用。【关键词】胃癌;SGC细胞;紫杉醇;顺铂;放疗【中图分类号】R734【文献标识码】A【文章编号10253-3685(2012)18—2134—03Sensitizingeff~tsofcombineduseofpaclitaxelandcisplatinintensivechemotherapyonradiotherapyingastriccancercellsinvitro,Mei,SUJun,XIAYingqiu.SchoolofPublicHealth,NaingMedicalUniversity,Nanj4、ing210029,CHINA[Abstract]ObjectiveToobservetheinvitrochangesofcellproliferationandcellcycleofgastriccancereelllineSGCunderwentcombineduseofpaclitaxelandcisplatinintensivechemotherapywithradiotherapy.MethodsTheSGCcellsculturedinvitrowereseededin96一wellplates,whichwereassigned5、into6groupsofP1(treatedwithpaclitaxel0.1ttg/m1),P2(treatedwithpaclitaxel0.01/zg/m1),C1(treatedwithcisplatin0.1ttg/m1),C2(treatedwithcisplatin0.01/~g/m1),PC1(P1+C1)andPC2(P2+C2).The4Gyradiotherapywasperformedundersterilecondition.Thedepressionrateofeellproliferationwascalcula6、tedwithMTTassay.Thechangesofapoptosisandcellcycleweredetectedbyflowcytometry.ResultsThedepressionratesofcellproliferationingroupsofPC1andPC2were(76.64-7.7)%and(68.3±2.6),whichwerehigherthan(46.7±4.5)%ingroupPl,(39.24-5.3)ingroupP2(41.4±o.2)ingroupC1,and(25.6±1.3)ingroupC2(P<7、0.01).TheSGCcellcyclesaftercombinationofpaclitaxel。cisplatinandradiotherapywereblockedmainlyatstageofG2/M,whichincontrolgroupweremainlyatstageofG1(P8、forgastriccancercellsinvitro.[Keywords]Gastriccancer;Paclitaxel;Cisplatin;R
