摘要 目的观察急性淋巴细胞白血病(ALL)患儿骨髓组织中miR-155表达变化,并探讨其临床意义。方法选择ALL患儿46例(观察组),非血液病儿童17例(对照组),采用qRT-PCR检测各组miR-155,并分析miR-155表达与ALL临床病理参数的关系。结果观察组及对照组miR-155相对表达量分别为(26.8±10.1)×10-4、(4.3±1.2)×10-4,两组比较,P<0.05。观察组低危型、中危型、高危型者miR-155相对表达量分别为(3.30±1.15)×10-4、(5.28±1.75)×10-4、(7.30±2.15)×10-4,两两比较,P均<0.05;治疗前及治疗第33天miR-155相对表达量分别为(9.30±4.15)×10-4、(3.30±0.15)×10-4,两者比较,P<0.05。结论 ALL患儿骨髓组织miR-155表达升高,miR-155高表达与儿童ALL的发生发展以及预后密切相关。
