[摘要] 目的 探讨一氧化氮(NO)以及一氧化氮合酶(NOS)对于再生障碍性贫血(AA)以及缺铁血性贫血(IDA)诊断及疗效判定的意义。方法 收集2010年1月—2013年9月期间,该院收治的AA患者24例作为AA组,并收集同期初诊IDA患者24例作为IDA组,选择同期健康体检者24例作为对照组,测定并对比分析3组的血清NO以及NOS水平。结果 AA组以及IDA组的血清NO浓度以及NOS活性均显著高于对照组(P<0.05),AA组和IDA组之间差异无统计学意义(P>0.05);经相应治疗后,AA组和IDA组的NO及NOS均恢复正常,且与对照组比较,差异无统计学意义(P>0.05)。结论 NO以及NOS可能参与了AA及IDA的发病过程,对于AA及IDA的诊断以及疗效判定均具有一定的意义。

[Abstract] Objective To investigate the significance of nitric oxide (NO) and nitric oxide synthase (NOS) for the diagnosis and curative effect evaluation of aplastic anemia (AA) and iron deficiency anemia (IDA). Methods 24 cases of AA patients admitted in our hospital from January, 2010 to September, 2013 were selected as the AA group, and 24 cases of patients newly diagnosed with IDA patients during the same period were selected as the IDA group, and 24 cases of healthy people underwent physical examination during the same period were selected as the control group. The serum NO and NOS levels of these three groups were measured, compared and analyzed. Results The serum NO concentration and NOS activity in AA group and IDA group were significantly higher than those of the control group (P<0.05), but there was no significant difference in serum NO concentration and NOS activity between AA group and IDA group (P>0.05); after treatment, the serum NO concentration and NOS activity in AA group and IDA group returned to normal, and compared with those of the control group, the difference was not statistically significant (P>0.05). Conclusion NO and NOS may be involved in the pathogenesis of AA and IDA, and which have certain significance in the diagnosis and curative effect judgment of AA and IDA.

一氧化氮(NO)以及一氧化氮合酶(NOS)是由L-精氨酸在催化作用下生成的脂溶性气体,两者的分子结构中均存在不配对电子,属于自由基。目前已有大量研究证实,NO在调节免疫系统、神经系统、心血管系统以及呼吸体统功能,并维持各系统生理平衡之中具有重要作用。NOS在体内诸多脏器细胞中均有分布,不同组织中由NOS所合成的NO生理功能存在一定的差异,且其所参与的病理过程也不同。目前临床研究发现,NO对于造血系统也具有一定的作用,NO与NOS在贫血发病中的作用也越来越受到医学界的关注[1]。该研究于2010年1月—2013年9月间主要通过检测再生障碍性贫血(AA)以及缺血性贫血(IDA)患者的血清NO及NOS,旨在探讨NO及NOS以AA、IDA之间的关系,现报道如下。
