摘要 目的:观察分化抑制因子4(Id4)在非霍奇金淋巴瘤组织(non-Hodgkin’s lymphoma,NHL)和反应性增生(RH)组织中的表达差异,及其与肿瘤增殖活性的关系,探讨Id4在淋巴瘤发生、发展中的可能作用。方法:选取2006~2008年郑州大学第一附属医院病理科存档石蜡标本80例,其中NHL70例,RH10例。应用免疫组织化学S-P法检测Id4和Ki-67分别在NHL和RH中的表达水平。结果:Id4在NHL中的表达率为35.7%(25/70),而在RH中的表达率为70.0%(7/10),两者之间存在统计学差异(P<0.05)。Ki-67在NHL中的表达率为75.7%(53/70),明显高于RH中的表达率10.0%(1/10,P<0.05),而且Ki-67阳性强度随着NHL恶性程度的增加而增高。Id4和Ki-67的表达与患者性别、年龄、免疫分型及肿瘤原发部位等因素无明显相关(P>0.05)。结论:Id4在NHL中的表达明显降低,可作为NHL与RH鉴别诊断的一个参考指标。
