简介：客观：借助于高分辨率图象分析(HRIA)预言食道的上皮的发育异常的结果。方法：无征状的成年人从Linxian县的Heshun公社在1983为食管的汽球细胞学被检查。93严重发育异常和食管的122温和发育异常被选择。借助于与电视照相机装备的一台Axiomat显微镜，在染色奶头的有鳞的上皮的中间的层的保存得很好的房间的100个正常原子核随机被检验。结果：93个cytologically诊断的严重发育异常盒子，24,14和7分别地在3，5和9年里进行了到癌。在另外的48个盒子中，发育异常仍然是马厩或regressed到正常。另外的盒子被用作控制。根据染色质特征，盒子的正确诊断被HRIA在75.0%完成(18/24)，85.7%(12/14)并且(6/7)85.7%盒子检验了，分别地(P<0.001)。122cytologically诊断的温和发育异常，16,13和12个盒子分别地在3，5和9年里进行了到癌。另外的81个盒子仍然是马厩或regressed到正常。正确诊断被HRIA在93.8%做(15/16)，76.9%(10/13)并且(10/12)833%盒子检验了，分别地(P<0.001)。结论：HRIA检验的染色质原子特征能预言癌症前期的损害的结果并且从non-progressor区别progressor。它能为chemo预防试用的效率的评估被用作代理人端点biomarkers。

简介：对在中间风险、高风险的子宫内膜的癌症的辅助治疗的实践和结果的现在的模式客观。有从1999～2006的中间风险、高风险的子宫内膜的癌症的224个女人上的方法回顾的数据被考察。所有病人经历了外科的阶段。辅助治疗的模式，加化疗由骨盆的放射疗法，化疗，和放射疗法组成，被估计。3年、5年的疾病特定的幸存(决策支持系统)率用Kaplan-Meier方法被计算。结果处于5年的决策支持系统率的差别在辅助的组和非辅助的组之间是统计上重要的(80.65%对63.80%，P=0.040)。在经历了辅助治疗的110个高风险的病人，两5年的决策支持系统率和周期性的率独自与放射疗法相比在联合放射疗法和化疗组是显著地不同的，化疗独自组织(决策支持系统率，P=0.049；周期性的率，P=0.047)。在经历了辅助治疗的83个中间风险的女人，在联合放射疗法之中处于5年的决策支持系统率和复发率没有重要差别，化疗，独自一个的放射疗法和化疗独自组织(决策支持系统率，P=0.776；周期性的率，P=0.937)。加化疗的结论辅助放射疗法在高风险的子宫内膜的癌症病人独自与独自一个的放射疗法和化疗相比与更高5年的决策支持系统率和更低的复发率被联系。有中间风险的子宫内膜的癌症的病人可能不是可能的得益于辅助联合放射疗法和化疗。

简介：目的：开发一个新奇方法由DHPLC检测CpGmethylation。方法：在DNA与钠重亚硫酸盐被对待以后，失配修理基因hMLHl倡导者被聚合酶链反应(PCR)放大。DHPLC被用来在他们的部分使中毒的温度分开PCR产品。BstUI消化试金也为比较学习被使用。结果：A294bp乐队被PCR在结肠癌房间线RKO和胃的癌症房间线PACM82的每件DNA样品以后获得。这二个乐队能被DHPLC在53掳C(为RKO的保留时间6.7min对为PACM82的6.2min)完全分开。当PACM82不是methylated时，自从methylation能保护C的变换到T并且在重亚硫酸盐治疗以后使更高的C/G满意，我们断定在RKO房间的hMLHl倡导者是methylated，导致推迟的时间。从BstUI消化试金的与那些一致的这些结果。结论：在hMLHl的CpG岛的Methylation能被DHPLC在重亚硫酸盐修正以后方便地检测。
