摘 要:目的:探讨中性粒细胞碱性磷酸酶(NAP)在急性髓系白血病(AML)患者中的表达情况及临床意义。方法:流式细胞术检测53例AML患者及50例正常对照组外周血NAP的表达水平;ELISA检测53例AML患者及50例正常对照组血浆中粒细胞一集落刺激因子(G.CSF)、中性粒细胞弹性蛋白酶(NE)、白细胞介素-8(IL-8)水平。结果:AML患者外周血NAP[1159(563~2033)AB/c]表达低于正常对照组[1862(1345~2382)AB/c],差异有统计学意义(P〈0.05);AML患者血浆中G-CSF、NE及IL-8[34.36(25.17~47.24)ng/L、397.56(324.63~563.84)pg/mL、585.34(403.61~866.54)pg/mL]表达低于正常对照组[54.52(46.27~77.14)ng/L、689.74(496.78~899.14)pg/mL、832.36(625.17~998.24)pg/mL],差异有统计学意L(P〈0.05)。AML患者外周血NAP的水平与血清中G.CSF水平呈正相关(r=0.621.P=0.007)。结论:AML外周血中NAP表达显著降低,同时伴随血浆中性粒细胞相关因子G—CSF、NE及IL-8分泌减少,推测AML患者中性粒细胞免疫功能受到抑制。Objective To investigate the expression of NAP in patients with acute myeloid leukemia (AML). Methods Expression of NAP of peripheral blood was assessed by flow cytometry. The serum levels of G-CSF, NE and IL-18 in 53 patients with AML and 50 healthy controls were examined by ELISA. Results The expression of NAP in AML patients [ 1 159(563 - 2 033)AB/c] was decreased than that of healthy controls [1 862(1 345 - 2 382)AB/c], (P 〈 0.05). The serum levels of G-CSF, NE and IL-8 from AML patients [34.36(25.17- 47.24) ng/L, 397.56(324.63- 563.84) pg/mL, 585.34(403.61 -866.54) pg/mL] were significantly lower than those of healthy controls [ 54.52 (46.27 - 77.14) ng/L, 689.74 (496.78 - 899.14) pg/mL, 832.36(625.17 - 998.24) pg/mL] (P 〈 0.05). The expression of NAP in AML patients was positively correlated with the serum level of G-CSF (r = 0.621, P = 0.007). Conclusions The decreased expression of NAP, G-CSF, NE and IL-8 in the peripheral blood with AML could speculated that neutrophils immune function in patients with AML was restrained.
