    Abstract: Abstract 4163 Background Acute myelogenous leukemia (AML) is generally looked upon as a heterogeneous group of different entities originating from the malignant transformation of a hematopoietic progenitor or stem cell. AML incidence increases with age. AML is associated with a poor prognosis, particularly in older patients. The poor prognosis in older adults is because of a combination of factors, including a larger proportion of cases with adverse-risk cytogenetics and other deleterious genetic and epigenetic changes, lower rates of achieving complete remission with intensive chemotherapy, higher risk of disease recurrence after achieving remission, greater comorbidity, inability to tolerate conventional allogeneic bone marrow transplantation regimens, and other adverse prognostic factors. The outlook for these patients remains dismal and little progress as been made in the last two decades. Current treatment of elderly AML consists of intensive chemotherapy with an anthracycline and a cytarabine. To evaluate our progress in the diagnosis, treatment and outcome of this condition, we reviewed the reports of 93 newly diagnosed acute myeloid leukaemia patients 〉 /=55 years of age admitted to our department between 2003 and 2007. Methods A retrospective chart review was performed of 93 patients 〉 /=55 years of age diagnosed with acute myeloid leukemia. The clinical efficacy was observed and the overall survival(OS) were analyzed. Results Median age of patients was 66 (range 55-88) years, 69 patients(74%) received a combination of an anthracycline and a cytarabine, either mitoxantrone per day on days 1, 2(MA),or 35 mg/m2 pirarubicin(TA) 7–8mg/m2 or idarubicin per day on days 1, 2 (IA). Each patient was given 100mg/m2 cytarabine intravenously per day for 7 days. And 24 patients (26%) were untreated. Total CR rate was 45% after 2 regimens. Only 3 patients happened to early death. The median period of the bone marrow depression is 19 days. The follow-up was ended at Aug 2008 year. Median survival of the treated patients was 256 days and it was significantly (P = 0.003) different from the untreated patients(66 days). Of the treated group, 7 patients were still alive, and the longest time was more than 6 years. Conclusions The prognosis of acute myeloid leukemia in older patients remains poor, but the anthracycline chemotherapy seems to improve the outcomes among older with AML. For this difficult patient cohort, it is a better treatment that can exert a more selective anti-leukaemic activity whilst not suppressing normal haemopoiesis or having significant systemic toxicities.

    Abstract: Background: Our preliminary research found that STAT3, IL-17A, and IL-21 expressed in cGVHD patients. So, we provide the blocking STAT3 signal to the induction of Treg cells differentiation, and to provide experimental basis on new targets of cGVHD immunotherapy. Methods: 1. Mice spleen CD4+ CD62L+ naiveT cells were separated by immune magnetic bead and then activated for 72 h. After 96 h infection with STAT3-shRNA and negative control lentivirus, the Th subgroup proportion were measured by flow cytometry. Th related cytokines levels test by Luminex. Real time quantitative PCR was to detect STAT3 and Th subgroup related transcription factor mRNA levels. CD117+ mouse bone marrow stem progenitor cells were sorted by flow cytometry, and transfected by STAT3-shRNA. Inhibition of STAT3 gene in mRNA level was measured at 96 h. Cell proliferation activity was test with CCK8 kit, and cell apoptosis rate determined by flow cytometry. Differentiation of CD117+ cells was induced by 2.2% of methyl cellulose and different cytokines. 2. BALB/c female mice, after the linear accelerator 700cGy of whole body irradiation, accepted miHA mismatched male B10. D2 mice bone marrow cells and spleen cells (8 x 106, 1:1). Randomly assigned 6 mice of cGVHD clinical score of 0.6 or above to each group. After STAT3-shRNA or negative control lentivirus treatment, the observe end point was 58th day after transplantation. The clinical and pathologic scores compared. Th17 and Treg cells measured by flow cytometry. Th related cytokines measured by Luminex. Purpose genes in blood and protein expression levels in target organs were found by Q-PCR and western blot test, respectively. Results: 1. The Th17 / Treg ratio of shRNA group was significantly decreased than that in the NC group (P 〈 0.05). Except for the Foxp3 gene, other purpose genes, including T-bet, Gata3, RORγt, TGFβ, Notch1, and Jagged2 mRNA levelsin interference group were cut. GM-CSF, IFN-gamma, beta, IL- 3, IL-2, IL-4, IL-6, TNF alpha, IL-17, IL-22a, IL-27, and IL-9 factor expression levels were significant difference between shRNA and negative control group (P 〈 0.05). There was no significant difference of cell proliferation activity, early apoptosis rate, and differentiation ability in STAT3-shRNA treated CD117+ bone marrow, compared with negative control group and blank control group (P 〉 0.05). 2. After 50th day, shRNA treatment group appear hair recovery, energy recovery, weight gain, shortness of breath better, mean of cGVHD score decreased. At the 58th day, clinical scores of cGVHD between shRNA treatment group and the negative control group overall mean difference was statistically significant (P 〈 0.05). cGVHD pathological score of lungs in shRNA treat group reduced (P 〈 0.05). STAT3mRNA levels in peripheral blood, phosphorylated STAT3, and STAT3 expression level of lung declined than control groups. The proportion of Th17 / Treg cells of spleen was significant reduced in shRNA group, compared with negative control group (P 〈 0.05). Conclusion: 1. STAT3 knocking down in naïve CD4 + Th cells induced the increased Treg cells, and the decreased Th17 cells. IL-2 confirmed to promote the growth of Treg cells. It speculated that blocking STAT3 might bring Th9 cells differentiation. STAT3 blocking in CD117+ stem progenitor cells have no significant effect on the proliferation, apoptosis and differentiation, validation the safety of STAT3-shRNA. 2. STAT3-shRNA treatment cGVHD mice in vivo achieved curative effect. The main target organs was the lung, which might be closely related to the fall in the proportion of Th17 /Treg. STAT3 may be used as a new target for immunotherapy of cGVHD.

CML-CP patients who received imatinib or transplantation from January 4, 2004 to October 10, 2011 in the Department of Hematology at Guangdong General Hospital (GGH) were enrolled in this study. A total of 131 patients, including 90 and 41 in the imatinib and allo-HSCT groups, respectively, were enrolled. The two groups including HRQOL investigation were well matched for gender, marital status, employment status, educational background, and Sokal score at diagnosis. There were no significant differences in the five-year EFS, PFS and OS between the two groups. The HRQOL was measured using EORTC QLQ-C30. Those questions include five multi-item function scales (Physical, Role, Emotional, Cognitive and Social Functioning), a combined Global Health Status/QOL scale, and a number of individual items (appetite loss, dyspnea, diarrhea, constipation, sleep disturbances, and financial impact). In terms of HRQOL, with the exception of social functioning (64.9 vs. 77.5, P=0.035), there was no significant difference in many of the HRQOL scores between the imatinib and transplant groups: global HRQOL, role function, physical function, emotional function and cognitive function. However, symptoms including nausea/vomiting (14.8 vs. 3.2, P=0.013), diarrhea (18.4 vs. 2.5, P=0.001), and financial difficulty (56.9 vs. 33.3, P=0.023) more negatively impacted the imatinib group (P 〈 0.05). Persistent cGVHD reduced the HRQOL of the allo-HSCT group, compared with the non-cGVHD and historic cGVHD group. Although imatinib and transplantation have similar long-term medical outcomes, allo-HSCT provides better social function, moderate symptoms, and lower financial burden. Thus, the role of allo-HSCT for CML-CP should be reevaluated in developing countries in the era of TKIs.

    Abstract: Xiaomei Chen and Jianyu Weng contributed equally to this study. The outcomes ofrelapsed or refractory acute myeloid leukemia (RR-AML) are poor and effective salvage regimens are urgently needed. We present a study of 14 patients with RR-AML (median age 42years, range 18-65years; male n=12, female n= 2) treated with CLAT regimen, which consisted of cladribine 5mg/m² per day i.v. 2-3 hour on days 1-5, cytarabine 1.0g/m² per day i.v. 4 hours after cladribine on days 1-5, topotecan 1.25mg/m² per day i.v. 4 hours after cytarabine on days1-5 and G-CSF 300ug per day subcutaneous injection on days until neutrophile granulocyte recovery. Total of fourteen patients were included into the study from June 2013 to June 2015, Two (14.3%) patients were relapsed and twelve (85.7%) patients were refractory, 4 of 14 patients were relapsed or refractory after allogeneic-HSCT. Two patients died of invasive fungal infection before the assessment. Seven patients (58.3%) achieved complete remission (CR), and one patient (8.3%) achieved partial remission (PR), the rest patients (33.3%) did not respond (NR). The overall response rate was 66.7%. Following CLAT treatment, four patients with CR underwent allogeneic hematopoietic stem cell transplantation (HSCT) or microtransplantation. The median relapse-free survival (RFS) for RR-AML patients receiving CLAT regimen was 8.6 (range 2-16) months. Thirteen patients developed grade 4 granulocytopenia and thrombocytopenia, the median duration was 13(range 2 to 21) days and12 (range 2 to 21) days, respectively. The most common non-hematological side effects included nausea, vomiting, diarrhoea, and were grade 1/2. The CLAT regimen seems promising for the treatment of patients, and it was well tolerated. This regimen offers an alternative treatment for those patients with RR-AML who have received severe intensive treatment, especially with anthracycline-containing chemotherapy.

    Abstract: Introduction The extensive diversity of the mature T-cell receptor(TCR) is determined primarily by the complementarity-determining regions (CDR3) of the TCR. The CDR3 of both TCRα and TCRβ genes is generated by extensive rearrangement and fusion between the V,D,and J segments and by random insertion and deletion of junctional nucleotides, which yields final products that are quite heterogeneous in size. As a result of these gene rearrangements, each T cell has a unique TCR and the diversity of the T-cell repertoire at any specific time can be characterized by the examination of CDR3 within that population. Using CDR3 spectratying technique, normal individuals demonstrate a highly diverse and polyclonal The aim of our study was to evaluate to investigate restricted expansion of TCR Vβ gene repertoire and the reconstitution of T cell receptor repertoire following allogeneic hematopoietic stem cell transplantation. Methods Patients Ten patients(9 males, 1 females; median age 31 years,range18–45) with 6 chronic myeloid leukemia-chronic phase and 4 cases of acute myelogenous lenkemia(CR1) who underwent HLA-matching sibling or unrelated BMT and/or peripheral blood stem cell transplantation (PBSCT) at our department between July 1999 and May 2000 were considered evaluable restricted expansion of TCR Vβ gene repertoire, the reconstitution of T cell receptor repertoire and oligoclonal T Cell Expansion in Chronic Graft-Versus-Host Disease. RT-PCR and Genes scan analysis (CDR 3 length analysis). Results Only 2-18Vβ genes were found in samples from these ten patients within one year, and there are different distribution in different patients. TCR repertoire complexity was abnormal in all patients, parts of the genes were expansion and part of them were suppressed. Samples from 9 patients with GVHD show V β3 in 7 cases, V β 8 and V β 23 in 6 patients. The results of genescan show that the PCR production of peripheral blood samples from these patients disply oligoclonal. Only 5–22Vβ subfamily T cells were found in samples from these patients whose transplantation more than one year. TCR repertoire complexity was abnormal in all patients. Discussion Following allogeneic BMT, regeneration of T-cell populations with a diverse repertoire can occure by at least two mechanisms: One mechanism is a thymic-dependent pathway, which presumably involves both negative and positive selection and recapitulates fetal ontogeny. Alternatively, regeneration of peripheral T cells may occur through thymic-independent mechanisms. All patients had marked abnormalities in their spectratypes, only 5-22Vβ subfamily T cells were found in samples from these patients, most of it was influenced after transplant, although the number of circulating CD3+ T lymphocytes in these patients have restored at normal lever by flow cytometic analysis, but the CD4+ T cell subset returned slowly in these patients resulting in an inversion of the normal CD4/CD8 ratio for more than 1 year after tuansplantation. Therefore, the analysis of TCRVβ subfamily is a usuaful methods and techniques for monitoring immune reconstitution after transplant.
