2、cadherin)、波形蛋白(Vimentin)和转化生长因子一p(TGF—p)表达的影响。方法40只小鼠随机分为肺复康组(17.2g生~/kg)、5一Fu组(25mg/kg)、Lewis肺癌模型组、正常组。检测肿瘤体积、肿瘤质量以及癌、癌旁组织中E—cadherin、Vimentin和TGF—B的蛋白表达情况。结果与模型组相比,肺复康组肿瘤体积减小(P<0.01),肿瘤质量降低(P<0.01);肺复康组抑瘤率为36%。与正常组比较,模型组癌及癌旁组织E—cadherin表达降低(P3、P<0.叭);与模型组癌及癌旁组织相比,肺复康组癌及癌旁组织E—cadherin表达升高(P0.05)。结论肺复康对Lewis肺癌小鼠肿瘤的生长具有一定的抑制作用;并能上调E—cadherin的表达,从而促进肿瘤细胞问的同质粘附而抑制肿瘤的侵袭、转移。[关键词]肺复康;Lewis肺癌;E一钙黏蛋白;波形蛋白;转化生长因子一B[中图分类号~R285.5;R734.2[文献标识码]A[文章编号]doi:10.3969/j.issn.1674—070X.2015.03.009.04、30.04EfectsofFeifukangontheGrowthofTumorandExpressionofE-cadherin,Vimentin.andTGF一13inMicewithLewisLungCancerX/ADan'2LIYongmins,TANXiooninf,KUANGChao2.GUOJiomheng'’。.SchoolofPharmacy,HunanUniversityofChineseMedicine,Changsha,Hunan410208,China,"2.HunanProvinceEducationDe5、partrnentKeyLaboratoryofModernizationofTraditionalChineseMedicine,Changsha,Hunan410208,China,3.HunanAcademyofTraditionalChineseMedicine,Changsha,Hunan410006,China)[Abstract]ObjectiveTostudytheFeifukangextractonthechangesofgrowthoftumorandlevelsofE—cadherin,Vimentin.andT6、GF-13incancerousandpara-carcinomatissuesofmicewithLewislungcancer.Methods40micewererandomlydividedintoFeifukang(17.2gcrudedrug&g),5-Fu(25mg/kg),modelandnormalgroup.Thetumorvolume,tumorweight,andtheexpressionsofE-cadherin,Vimentin,andTGF-13incancerousandpara-carcinomatis7、suesweremeasured.ResultsComparedwithmodelgroup,thetumorvolumeandweightinFeifukanggroupwassignificantlydecreased(P(0.o1),andthetumorinhibitoryrateinFeifukanggroupwas36%.Comparedwithnormalgroup,expressionsofE-eadherinweresignificantlydecreased(P<0.O1),expressionsofvimenti8、nandTGF—pincancerousandpara—carcinomatissuesofmodelgroupweresignificantlyincreasedfp<0.01).Comparedwiththeexpr
