Objective To investigate the therapeutic effects and adverse reactions of decitabine combined with IA or CAG regimen in the treatment of elderly patients with acute myeloid leukemia.Methods A retrospective analysis was made to observe the therapeutic effects and adverse reactions of 47 elderly patients with acute myeloid leukemia,who were divided into DAC+IA group (17 cases) and DAC+CAG group (28 cases) according to the different chemotherapy.Results In DAC+IA group,the rate of complete remission was 29.4 ％ (5/17),the rate of partial remission was 35.3 ％ (6/17),the effective rate was 64.7 ％ (11/17).In DAC+CAG group,the rate of complete remission was 26.7 ％ (8/30),the rate of partial remission was 30.0 ％ (9/30),the effective rate was 56.7 ％ (17/30),the difference between the two groups was not statistically significant (x2 =0.227,P =0.716).In DAC+IA group the median remission time and the median suvival time were 4.0 and 8.1 months,respectively.And they were 4.0 and 8.1 months,respectively,in DAC+CAG group.No significant difference was showed between the two groups (P value was 0.835,0.266,respectively).Conclusions Compared with decitabine combined with CAG regimen,decitabine combined with IA regimen has similar effect and can be well tolerated.Accordingly,decitabine combined with IA regimen can be used as first-line treatment for elderly patients with acute myeloid leukemia.

BACKGROUND:Alogeneic hematopoietic stem cel transplantation (alo-HSCT) is an effective mean to cure severe aplastic anemia, and especialy haplotype transplantation is regarded as a transplantation system with Chinese characteristics, and rank at the international leading level. OBJECTIVE:To explore the patterns of haplotype alo-HSCT as a new immune tolerance method for severe aplastic anemia and to solve the transplantation rejection and graft-versus-host disease. METHODS:Twelve patients with severe aplastic anemia who underwent haplotype alo-HSCT at the Department of Hematology, General Hospital of Beijing Military Area, China from April 2013 to May 2014 were enroled. Al these patients received the new regimen of inducing immune tolerance through the application of high-dose cyclophosphamide (400 mg/m2, consecutively 3 days before transplantation; 50 mg/kg, consecutively 3 days after haplotype transplantation). RESULTS AND CONCLUSION:The median time of neutrophil recovery was 17 (13-21) days, and the median time of platelet recovery was 21 (15-31) days. After transplantation, there were one case of degree II acute graft-versus-host disease and one case of chronic graft-versus-host disease, both of which were controled. The folow-up time was 6 months at least, and the median time was 11 months. During the folow-up, one case died of rejection reaction and one case died of severe lung infection. These findings indicate that the new method of inducing immune tolerance with high-dose cyclophosphamide after transplantation for severe aplastic anemia has significant effects in reducing graft-versus-host disease and transplantation-related mortality rate.

Objective To evaluate the relationship between the amount of grafted cells and the incidence of acute graft versus host disease (aGVHD) after haploid hematopoietic stem cell transplantation (haplo-HSCT). Methods Data of 68 patients who underwent haplo-HSCT from Jan 2009 to Dec 2013 were analyzed retrospectively. Influences of different factors on the incidence of Ⅲ-Ⅳ degree of aGVHD after HSCT were evaluated. Results 68 patients including 42 males and 26 females were 5/10-9/10 HLA match with 19 father donors, 24 mother donors, 16 sibling donors and 9 children donors. 51 patients not suffered Ⅲ-Ⅳdegree of aGVHD included 32 males and 19 females with the mean age of 20 years old (5-55 years old). 17 patients sufferedⅢ-Ⅳdegree of aGVHD including 10 males and 7 females with the mean age of 23 years old (5-54 years old). There were no significant differences in the amount of the grafted mononuclear cells (MNC) and CD34+cells, and the white blood cell counts (WBC) and platelet count (Plt) recovered time between two groups (P>0.05). However, MNC number was related to CD34+cell number (P<0.05) and WBC recover time (P<0.05), and the CD34+cells number was related to WBC and Plt recover time (P< 0.05). Conclusion The incidence of Ⅲ-Ⅳ degree of aGVHD is unrelated to the amount of grafted MNC, and CD34+cells.

Objective To improve the diagnosis efficiency of patients with angioimmunoblastic T-cell lymphoma (AILT)by analyzing the clinical characteristics and curative effect of AILT. Methods Retrospective studies were used on clinicopathological features,immunophenotypes,treatment and survival of 20 angioimmunoblastic T-cell lymphoma patients,who were collected between January 2005 and January 2010 of Beijing Military General Hospital. Results In the 20 patients receiving chemotherapy,the median age was 55.9 years old.All of the 20 had lymph nodes and 11 of whom were accompanied with B group of symptoms,which were confirmed by lymph node biopsy and T cell antigen CD3, CD45Ro positive expression in all the patients. ALL of the patients received the CHOP regimen and combining with other treatment such as DICE,ESHAP, Hyper-CVAD or autologous hematopoietic stem cell transplantation. A follow-up by 5 to 69 months showed that median survival was 20.2 (5-69) months and 1,2,and 3-year disease free survival (DFS) were 67 ％,33 ％,and 11％ respectively.8 patients of the group (40 ％) with a sustained remission (CCS) respectively survived 63,47,27,24,24,12,5,1 months so far.Conclusion Most patients were older with many complications during chemotherapy, which resulted in easy relapse, and even the symptoms were alleviated at the early stage of the chemotherapy. IPI prognostic index is more important with long-term survival in AITL.Therefore further studies are required to improve the outcome.

Objective To investigate the effect of donor lymphocyte infusion (DLI) for preventing relapse of leukemia after haplotype hematopoietic stem cell transplantation (HSCT), and evaluate the therapeutic effect and the safety of DLI. Methods The 20 haplotype HSCT patients who received DLI were studied for the occurrence of graft-versus-host disease (GVHD) and long-term survival. Results Eleven of twenty patients survived leukemia-free for a median of 25(4-60) months, and leukemia-free survival rate was 55 %. 9 cases died of relapse. 19 patients occurred acute GEHD (aGVHD) after received DLI, 4 of them were severe.Conclusion The prophylactic DLI is effective for preventing from relapse of leukemia. It might be feasible option.

BACKGROUND:Al ogeneic hematopoietic stem cel transplantation is currently recognized as the first-line therapy for severe aplastic anemia. However, with the popularity of the one-child families, the source of ful y matched hematopoietic stem cel transplantation is limited, so haploidentical hematopoietic stem cel transplantation is favored. OBJECTIVE:To retrospectively compare and analyze the clinical efficacy and safety of haploidentical al ogeneic hematopoietic stem cel transplantation and ful y matched hematopoietic stem cel transplantation for the treatment of severe aplastic anemia. METHODS:Clinical data of 15 patients with severe aplastic anemia (treatment group) who underwent haploidentical al ogeneic hematopoietic stem cel transplantation in the Department of Hematology General Hospital of Beijing Military Region from January 2013 to January 2015 were retrospectively analyzed. Pretreatment regimen was cyclophosphamide, fludarabine, Busulfex, combined with anti-human lymphocyte immune globulin. Donors received granulocyte colony-stimulating factor, and the transplantation method was bone marrow mobilization combined with peripheral blood stem cel transplantation. Combined immunosuppressive agents including cyclosporine A, methotrexate, tacrolimus, were adopted for prevention of graft versus host disease. Another 15 cases of severe aplastic anemia undergoing ful y matched hematopoietic stem cel transplantation served as control group over the same period. Complications and survival of the two groups were statistical y analyzed. RESULTS AND CONCLUSION:By the end of July 2015, the median fol ow-up time of the treatment group was 20.7 months (6-30 months), and hematopoietic reconstruction was achieved in al cases, including four cases of graft versus host disease, five cases of pulmonary infection, three cases of sepsis, and one case died of pulmonary infection, one cases died of sepsis, and two cases died of graft versus host disease. In the control group, the median fol ow-up time was 19.7 months (5-28 months), hematopoietic reconstruction was achieved in al cases. There were three cases of graft versus host disease, four cases of pulmonary infection, one case died of pulmonary infection, and two cases died of graft versus host disease. The total survival rates of the two groups were 73%and 80%respectively, with no significant difference (P=0.67). The haploidentical al ogeneic hematopoietic stem cel transplantation for severe aplastic anemia is safe and effective, and the clinical efficacy is comparable to the ful y matched hematopoietic stem cel transplantation.

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,+1 2 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 201 3 to January 201 4,including 4 male and 8 fe-male,with average age of 7.92 years old(3 -1 4 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,+1 2 months after transplantation dynamically in the peripheral blood.While in the same period the level of T lymphocyte subsets was monitored in 1 2 cases of healthy children at the same period as the healthy control group.Results Fol-lowed up to March 201 5,1 0 cases had abnormal cellular immunity (CD4 +/CD8 + ratio inversion)in the 1 2 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 (1 6.73 ±3.70)% respectively(P =0.000),CD4 +CD25 high +FOXP3 + was decreased by (3.3 ± 1 .5)% and (8.1 ±1 .3)% respectively (P =0.003),whose difference was statistically significant (P <0.05).The lever of CD3 +,CD4 +,CD8 +,CD4 +/CD8 +,CD56 +,CD4 +CD25 high +FOXP3 + had a different degree of recovery after transplantation for all cases and returned to normal in +1 2 months basically.In +1 ,+3,+6,+1 2 months after transplantation,the levels of CD4 +CD25 high +FOXP3 + in GVHD positive group and negative group were (0.4 ± 0.6)% and (1 .6 ±0.7)% respectively,(0.7 ±0.3)% and (2.7 ±0.4)% respectively,(1 .1 ±0.5 )% and (2.9 ±0.7)% respectively,(1 .4 ±0.3)% and (3.6 ±0.2)% respectively,which had statistical significance (P <0.05).Conclusions There was abnormal cell immune function in some cases with AA.After transplantation,the level of CD4 +CD25 high +FOXP3 + is closely related to the acute GVHD,which can be used to predict the occurrence of GVHD.
