摘要目的：观察初发急性髓系白血病（AML）患者血清中巨噬细胞炎症蛋白-1α（MIP-1α）、干扰素γ诱导蛋白10（IP-10）、血管生成素-1（Ang-1）的表达水平，探讨其在 AML 发病中的临床意义。方法采用ELISA 法检测54例初发 AML 患者（观察组）、20例健康者（健康对照组）血清 MIP-1α、IP-10、Ang-1的含量。结果观察组 MIP-1α、IP-10、Ang-1的含量[（198．813±53．923）pg／mL、（2．332±0．745）ng／mL、（1．593±0．447）ng／mL]均明显高于健康对照组[（153．309±44．475）pg／mL、（1．569±0．485）ng／mL、（0．838±0．333）ng／mL]（t ＝3．369、5．133、6．856，均 P ＜0．05）。亚组分析，在预后良好组、预后中等组、预后不良组中， MIP-1α的含量分别为（141．524±27．510）pg／mL、（196．370±31．966）pg／mL、（269．892±54．795）pg／mL， IP-10的含量分别为（2．085±0．332）ng／mL、（2．307±0．696）ng／mL、（2．685±0．348）ng／mL，Ang-1的含量分别为（1．248±0．454）ng／mL、（1．5999±0．386）ng／mL、（1．951±0．359）ng／mL。预后良好组 MIP-1α、Ang-1表达水平显著低于预后中等组和预后不良组（q ＝6．100、11．438、3．603，5．742，均 P ＜0．05）。但 IP-10的含量与NCCN 预后分组无相关性（q ＝1．225、2．643、2．016，均 P ＞0．05）。观察组血清 MIP-1α、Ang-1表达呈正相关关系（r ＝0．324，P ＜0．05）。结论初发 AML 患者血清 MIP-1α、IP-10、Ang-1的含量在不同预后分组中存在差异，提示其可能对患者临床治疗方案的选择及预后判断有一定的指导意义。

abstractsObjective To study the expression of macrophage inflammatory protein-1α(MIP-1α),inter-feron gamma inducible protein 10(IP -10)and angiopoietin -1 (Ang -1)in primary acute myelogenous leukemia (AML),and clarify their clinical significance.Methods ELISA was used to detect the expressions of MIP -1α,IP-10 and Ang -1 in serum samples from 54 AML patients(observation group),and twenty volunteers(normal control&nbsp;group).Results The expression levels of MIP -1α,IP -10 and Ang -1 in the observation group[(198.813 ± 53.923)pg/mL,(2.332 ±0.745)ng/mL,(1.593 ±0.447)ng/mL]were significantly higher than the normal control group[(153.309 ±44.475)pg/mL,(1.569 ±0.485)ng/mL,(0.838 ±0.333)ng/mL](t =3.369,5.133,6.856, all P <0.05).Subgroup analysis,during the groups of better -risk,intermediate -risk and poor -risk,the contents of MIP -1αwere (141.524 ±27.510)pg/mL,(196.370 ±31.966)pg/mL,(269.892 ±54.795)pg/mL;the contents of IP -10 were (2.085 ±0.332)ng/mL,(2.307 ±0.696)ng/mL,(2.685 ±0.348)ng/mL;the contents of Ang -1 were (1.248 ±0.454)ng/mL,(1.599 ±0.386)ng/mL,(1.951 ±0.359)ng/mL.The levels of MIP -1αand Ang -1 in the better -risk group were significantly lower than those in the intermediate -risk group and poor -risk group (q =6.100,11.438,3.603,5.742,all P <0.05).While the levels of IP -10 had no closely correlation with NCCN risk status(q =1.225,2.643,2.016,all P >0.05).There were remarkable correlation between the serum expression levels of MIP -1αand Ang -1 (r =0.324,P <0.05).Conclusion There are differences of serum MIP -1α, IP -10 and Ang -1 in the different NCCN prognosis groups,which reflect they may have certain guiding significance in the choice of clinical treatment and the prognosis for newly diagnosed AML.
