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：得到中央neurocytoma的更好的识别并且减少的目的错误诊断。回顾的评论识别了中央neurocytoma的15个盒子的方法。中央neurocytoma的所有情况为他们的临床的症状，病理学的变化，染色的immunohistochemical，预后和微分诊断被分析。临床列在后面在上面被执行。在那里的结果1064年是8男性和7女性(中部32.93年)。最普通的介绍症状是与增加的intracranial压力(ICP)有关的那些，包括头疼(100%)，papilledema(93%)并且呕吐(80%)。所有肿瘤位于室的系统。肿瘤由一致房间组成与围着原子核和一个好染色质模式，并且在一些区域，有perinuclear光圈的小房间能被看见。特别地，无核的区域可以有一个好fibrillary矩阵(neuropil)。原子atypia和脉管的增长分别地出现在二种情况中。焦点的坏死能在一种情况中被看见。Immunohistochemical调查结果包括了synaptophysin(15/15)的表示，神经原特定的enolase(12/15)和glialfibrillary酸的蛋白质(GFAP)(3/15)。MIB-1增长索引从0.812.5%，并且在估计的15个盒子中的3个中是超过2%。11个病人的后续信息是可得到的。结论中央neurocytoma一般来说，但是在里面有有利预后一些情况，临床的功课能是好攻击的。GFAP确实，增长索引和脉管的增长的增加可能建议一个更恶意的过程。
