Analysis of efficacy and prognostic factors of allogeneic hematopoietic stem cell transplantation in treatment of relapsed/refractory acute myeloid leukemia / 白血病·淋巴瘤

Objective:To explore the efficacy and prognostic factors of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of relapsed/refractory acute myeloid leukemia (AML).Methods:The clinical data of 35 patients with relapsed/refractory AML treated with allo-HSCT in the Affiliated Cancer Hospital of Zhengzhou University from June 2011 to October 2018 was retrospectively analyzed. The overall survival (OS), disease-free survival (DFS), graft versus host disease (GVHD) incidence, transplantation related mortality and recurrence rate were calculated, and the risk factors affecting prognosis were analyzed.Results:Hematopoietic reconstitution was obtained in all patients after transplantation. The 100 d incidence of grade Ⅱ-Ⅳ acute GVHD was (22.9±7.7)%, and the 3-year incidence of chronic GVHD was (49.5±10.60)%. The median follow-up time after transplantation was 14.1 months (4.2-89.4 months). In all cases, 18 cases survived (including 16 cases of DFS), and 17 cases died. Fourteen cases relapsed, and the median recurrence time was 4.7 months (2.9-32.4 months). The 3-year OS rate and DFS rate were (44.4±9.3)% and (43.0±9.5)%, respectively. Univariate analysis showed that the non-remission disease before transplantation, poor genetic risk grade before transplantation and recurrence after transplantation were the risk factors for OS (all P < 0.05). The 3-year OS rates in complete remission before transplantation group and non-remission before transplantation group were (63.2±12.0)% and (15.7±12.8)% ( P = 0.025), the 3-year DFS rates were (62.2±12.3)% and (15.3±12.7)% ( P = 0.028), and the 3-year recurrence rates were (28.2±10.7)% and (80.6±15.7)% ( P = 0.057). The 3-year recurrence rate in genetic high-risk group was higher than that in middle-risk group and low-risk group [100.0%, (45.0±12.1)% and (14.3±13.2)%, P = 0.045]. The 3-year tansplantation related mortality was (18.7±7.7)%. Conclusions:Allo-HSCT is an effective method for salvage treatment of relapsed/refractory AML, and recurrence is the main factor affecting survival. Reducing tumor load before transplantation is very important for reducing recurrence and improving curative effect.

Cloning and analysis of a powdery mildew responsive gene CmSAMDC from Cucumis melo L / 生物工程学报

In order to investigate the effect of S-adenosylmethionine decarboxylase (SAMDC) gene in melon resistance to powdery mildew, according to the previous results of EST sequences from cDNA-AFLP library and the melon genome sequence data, the SAMDC gene was isolated from Chinese wild melon clone 'Yuntian930' by RT-PCR and designated as CmSAMDC (GenBank Accession No. KF151861). The mORF (main open reading frame) was 1 095 bp encoding 364 amino acids with a molecular mass of 40 kDa. The predicted protein sequence showed high similarity with Cucumis sativus and Citrofortunella microcarpa. The SDS-PAGE showed that the expression protein was a fusion protein with the molecular weight of 40 kDa, which perfectly matched the mass calculated from the amino acid sequence. Quantitative real-time PCR analysis indicated that the expression level of CmSAMDC reached a maximum at 48 hpi (hours post inoculation) that over 7-fold to 0 hpi, and the expression of CmSAMDC was also detected in tendril, root, leaf and stem. These results indicate that CmSAMDC gene may play protective roles in melon resistance to powdery mildew infection.
