摘 要:目的通过动态监测再生障碍性贫血(AA)患儿行异基因造血干细胞移植后+1、+3、+6和+12个月CD3^+、CD4^+、CD8^+、CD4^+/CD8^+、CD56^+、CD4^+CD25high^+FOXP3^+水平,探讨AA患儿免疫功能与发病机制之间的关系及与发生移植物抗宿主病(GVHD)的意义。方法选取2013年1月至2014年1月在安徽医科大学附属北京军区总医院血液科行异基因造血干细胞移植的12例AA患儿,其中男4例,女8例;平均年龄7.92(3—14)岁;人类白细胞抗原(HLA)配型全相合5例,HIA配型不全相合7例。采用流式细胞术动态监测AA患儿移植前及移植后+1、+3、+6和+12个月CD3^+、CD4^+、CD8^+、CD4^+/CD8^+、CD56^+、CD4^+CD25high^+FOXP3^+水平,健康对照组同期监测的12例健康儿童T淋巴细胞亚群水平。结果随访至2015年3月,移植前12例AA患儿中10例存在细胞免疫异常(CD4^+/CD8^+比值倒置),与健康对照组相比,AA患儿移植前CD3^+细胞略高、分别为(66.79±7.35)%和(62.74±5.58)%(P=0.043),CD4^+细胞减低,分别为(33.73±7.26)%和(39.54±3.46)%(P=0.037),CD8^+细胞明显增高,分别为(35.69±6.78)%和(25.34±4.36)%(P=0.000),CD4^+/CD8^+比值明显减低,分别为1.23±0.56和1.78±0.34(P=0.001),CD56^+细胞明显降低,分别为(7.46±2.80)%和(16.73±3.70)%(P=0.000),CD4^+CD25high^+FOXP3^+细胞明显降低,分别为(3.3±1.5)%和(8.1±1.3)%(P=0.003),差异均有统计学意义(P均〈0.05)。移植后患儿CD3^+、CD4^+、CD8^+、CD4^+/CD8^+、CD56^+、CD4^+CD25high^+FOXP3^+水平都有不同程度的恢复,基本在+12个月恢复正常。移植后+1、+3、+6和+12个月,CD4^+CD25high^+FOXP3^+水平在GVHD阳性组与阴性组分别为(0.4±0.6)%和Objective To explore the clinical significance of the relationship between the immune function and the pathogenesis of aplastic anemia in children with aplastic anemia(AA) ,along with the incidence of graft versus host disease (GVHD) by monitoring the changes of T lymphocyte subsets dynamically in + 1, + 3, + 6, + 12 months for blood disease patients after allogeneic hematopoietic stem cell transplantation. Methods Twelve AA patients re- ceived allogeneic hematopoietic stem cell transplantation in Department of Hematology, the Affiliated General Hospital of Beijing Military Region of Anhui Medical University,from January 2013 to January 2014 ,including 4 male and 8 fe- male, with average age of 7.92 years old(3 -14 years old) with 5 cases of human leukocyte antigen (HLA) matched and 7 cases of HLA mismatched. The level of T lymphocyte subsets including CD3^+ , CD4 ^+ , CD8^+ , CD4^+/CD8^+ , CD56^+ , CD4^+ CD25 high^+ FOXP3^+ were monitored with flow cytometry before transplantation and in + 1, + 3, + 6, + 12 months after transplantation dynamically in the peripheral blood. While in the same period the level of T lymphocyte subsets was monitored in 12 cases of healthy children at the same period as the healthy control group. Results Fol- lowed up to March 2015,10 cases had abnormal cellular immunity (CD4^+ /CD8^+ ratio inversion) in the 12 AA pa- tients. Compared with the control group, in the AA group, CD3^+ was slightly higher, (66.79± 7.35) % and (62.74 ± 5.58 ) % respectively ( P = 0.043 ), CD4^+ was decreased by ( 33.73 ± 7.26) % and ( 39.54 ± 3.46 ) % respectively (P = 0.037 ), CD8^+ was increased by (35.69 ± 6.78 ) % and (25.34 ± 4.36) %, respectively ( P = 0.000), CD4^+ / CD8 ^+ decreased by 1.23±0.56 and 1.78± 0.34 respectively ( P = 0. 001 ) and CD56^+ was decreased by (7.46 ± 2.80)% and (16.73 ±3.70)% respectively (P =0. 000) ,CD4^+ CD25 high+ FOXP3^+ was decreased by
