1、陕西中医学院硕士学位论文培元抗癌汤对H22瘤株移植瘤小鼠端粒酶和C--myc癌基因表达影响的实验研究姓名:吴昭利申请学位级别:硕士专业:中西医结合临床指导教师:李仁廷201204摘要rlUrPlflllllfflfIIffllffIIfflllIllflUf\2109708目的:建造移植型动物模型(腹水型瘤株移植瘤小鼠)模型,来探讨培元抗癌汤对肝癌小鼠的癌细胞生长的影响及作用机制,通过对端粒酶和C-myc致癌基因表达来分析,进而为培元抗癌汤在临床上的应用提供理论依据。方法:将90只健康昆明小鼠中提取15
2、只作为空白对照组(A组),剩余75只小鼠分别在腋下种植相同量的H22腹水型瘤株悬液,共同造膜,将造膜成功的小鼠纳入60只,随即分为4组。分别为:空白对照组(A组),荷瘤对照组(B组),替加氟组(C组),培元抗癌汤组(D组),培元抗癌汤(中剂量)十替加氟组(E组)。各组小鼠分别给予相应实验药物灌胃,灌胃一次一日,连用14天药。每日观察小鼠一般情况、体重、及死亡等情况并详细记录,第15天将所有小鼠进行处死,取瘤组织、胸腺、组织、脾脏。测量其重量,计算抑瘤率,免疫器官(胸腺、脾脏)指数,同时按组别固定瘤块,免
3、疫组化法检测端粒酶和C-myc致癌基因表达情况,并分析两者间的相关性。结果:l、培元抗癌汤组、替加氟组及培元抗癌汤+替加氟组荷瘤小鼠瘤体重量明显小于荷瘤对照组(P4、元抗癌汤能抑制移植性H22荷瘤小鼠瘤体的生长,保护小鼠的正常脏器功能,提高免疫功能。其机制和下调端粒酶和C-myc致癌基因的表达水平有关。关键词:培元抗癌汤;H22腹水型肝癌;免疫组化;端粒酶;C-myc。TheeffectofPeiYuanKangAiTangoftheexpressionOfteIomeraseandC—myconcogeneinH22transpIantationTumorMiceAbstractObjective:Tobuiidthetransplantanimalmodels(5、ascitestumorstraintransplantedtumorsinmice)modeltoexploretheeffectandmechanismofPeiyuananticancerdecoctionon1ivercancerinmice,thegrowthofcancercells,telomeraseandC—myconcogeneexpressionanalysis,andthusprovidetheexperimentalbasisinclinicalPeiYuanKangAiTan6、g.Method:Withdraws1590healthKunmingmouseinastheblankcontrolgroup(Agroup),thesurplus75micehangthefluidseparatelyinarmpitplantercommensurability’SH22ascites1ump,makesthemembranetogether,willmakethemembranesuccessfulmousetointegrate60.dividesinto4groupsimme7、diately.Respectivelyis:Theblankcontrolgroup(Agroup),theDutchiumpcontrolgroup(Bgroup),foraddsthefluorinegroup(Cgroup),PeiYuanKangAiTangZu(Dgroup),PeiYuanKangAiTang(dosage)+fortoaddthefluorinegroup(Egroup).Eachgroupofmicegivethecorrespondingexperimentmedic8、inetofillthestomachseparately,filIsstomachonetimeonfirst,isusedtogether14dayofmedicine.Observesthemousemotion,theordinarycircumstances,thebodyweighteveryday,andsituationsandthedetailedrecordandSOondeath,the15thdaywiIiposse
