               [摘   要] 目的:探讨伴 FMS 样酪氨酸激酶 3 受体(FMS like tyrosine kinase 3 receptor,FLT3)突变的初诊急性髓系白血病
               (acute myeloid leukemia,AML)患者外周血淋巴细胞亚群、细胞因子表达水平及其与血细胞计数、突变类型之间的相关性。
                方法:168 例伴FLT3突变的AML患者纳入研究,进一步对FLT3突变类型进行分类,收集患者治疗前外周血淋巴细胞亚群、细
                胞因子数据及血细胞计数,分析其之间的相关性。结果:与健康对照组相比,伴FLT3突变的AML患者治疗前外周血CD4、白介

                AML患者的血细胞计数及FLT3突变类型与淋巴细胞亚群和细胞因子的表达水平有关,可能有助于AML危险分层并对AML患者
                的预后有一定影响。

               [Abstract] Objective:To investigate the peripheral blood lymphocyte subsets and cytokine expression levels in newly diagnosed
                acute myeloid leukemia(AML)patients with FMS like tyrosine kinase 3 receptor(FLT3)mutations,and their correlation with blood cell
                counts and mutation types. Methods:A total of 168 AML patients with FLT3 mutations were included in the study. The FLT3 mutation
                types were further classified,and the lymphocyte subsets,cytokines and blood cell count in peripheral blood of patients before
                treatment were collected to analyze their correlation. Results:Compared with the healthy control group,the expression levels of CD4,
                interleukin 6(IL ⁃ 6),and IL ⁃ 10 in peripheral blood of patients with FLT3 mutations were increased before treatment,while the
                expression levels of CD8,CD16 + CD56,IL ⁃ 2,tumor necrosis factor(TNF),and interferon gamma(IFN ⁃ γ)were decreased.
                According to leukocyte count,the distributions of CD3,CD4,CD8,CD19,IL⁃4 and IL⁃10 were different among the groups(P=0.039,
                P=0.024,P=0.034,P=0.008,P=0.048,P=0.024). According to platelet count,the distributions of CD19,CD16+CD56 were different

                                                                                            +
                                                                   +
                                                                             +
                among groups(P=0.030,P=0.045). It can be divided into FLT3⁃ITD 、FLT3⁃TKD 、FLT3⁃(ITD +TKD )and FLT3⁃(ITD +TKD ).
