简介:客观:为了学习表达式和apoptosis的临床的价值,在乳癌控制基因bcl-2和bax。方法:在在1996在我们的医院里从操作获得的41乳癌的蛋白质bax和bcl-2与正常的胸纸巾用ABCimmunohistochemical污点试金并且与10个盒子相比被检测。结果:在正常的胸组织的bax的积极的率是90%并且在乳癌是59%,与他们之间的重要统计差别(P<0.05),但是在bcl-2没有统计差别蛋白质表示。在41乳癌之中,有淋巴节点转移(21个盒子)的组有显然低的bax表示(43%)和高bcl-2表示(76%),给没有淋巴节点转移的组显示出重要差别(P<0.05)。结论:bcl-2的antiapoptosis功能是比在乳癌的bax强壮的。蛋白质bax和bcl-2试金可能在理解乳癌的生物行为是有用的。

简介:目的研究扶正固本颗粒联合顺铂对荷瘤小鼠体内抗肿瘤治疗及T细胞免疫调节的影响。方法选取昆明种小鼠120只,雌雄各半,随机分为6组,每组20只,建立小鼠S180腹腔积液瘤模型。空白组,无任何处理;模型组:等体积蒸馏水灌胃;化疗组:顺铂注射液(1mg/kg)腹腔注射;低、中、高剂量组:顺铂注射液(1mg/kg)腹腔注射联合扶正固本颗粒(5.625、11.250、22.500g/kg)灌胃给药,每日给药1次,共10天,观察小鼠一般情况,记录体重变化,计算抑瘤率、脏器指数,流式细胞仪检测小鼠外周血中CD4^+、CD8^+及T淋巴细胞亚群水平。结果化疗组和低、中、高剂量组的抑瘤率分别为65.5%、43.2%、44.0%、57.6%。与化疗组比较,低、中、高剂量组小鼠体重与血液中Th1/Th2水平均提高;中、高剂量组小鼠胸腺指数和血液中CD4^+、Th1、Th17水平均提高,CD8^+水平降低;高剂量组小鼠血液中Th2、Treg水平下降,Th17/Treg水平提高,差异均有统计学意义(P﹤0.05)。结论顺铂联合高剂量扶正固本颗粒治疗较单独化疗能增强荷瘤小鼠T细胞免疫。
简介:目的:探讨塔斯品碱衍生物TPD7对乳腺癌细胞MCF-7和ZR-75-30细胞迁移和侵袭的影响,阐明TPD7抑制细胞迁移和侵袭可能的作用机制。方法:采用细胞划痕法、Transwell小室侵袭法检测MCF-7和ZR-75-30细胞的迁移和侵袭。采用Westernblot法检测MMP9、β-catenin及c-Myc的蛋白表达。RT-PCR法检测β-catenin及c-Myc的mRNA表达。结果:TPD7对MCF-7细胞和ZR-75-30细胞迁移和侵袭均有显著抑制作用,且下调MMP9、β-catenin、c-Myc的蛋白表达和mRNA表达,呈剂量依赖性。结论:TPD7抑制乳腺癌MCF-7和ZR-75-30细胞迁移和侵袭,可能是通过Wnt信号通路抑制上皮-间质转化。

简介:目的总结门静脉压力(FPP)≥35cmH2O肝癌病人的外科治疗经验。方法回顾性分析1998年1月至2004年10月外科手术的11例FPP≥35cmH2O肝癌病人的手术资料、术后近期并发症及随访情况。结果全部病例手术均获得成功,无术中死亡。围手术期死亡率18.2%,术后并发症发生率100%,其中因上消化道大出血及肝功能衰竭死亡各2例(36.4%)。术后3mo、6mo及1年、2年、3年生存率分别为63.4%、36.4%、18.2%、18.2%、0%。结论FPP≥35cmH2O肝癌病人的手术切除有较高的并发症和死亡率,因此作者建议应将FPP≥35cmH2O肝癌视为肝部分切除的相对禁忌症。
