This study was aimed to examine the expression and promoter CpG island methylation of homeobox B4 (HOXB4) gene in CD34(+) cells from cord blood and peripheral blood mononuclear cells (PBMNCs) from health adult, and to investigate the expression level of HOXB4 in these two cells and its relationship with the promoter methylation. Semi-quantitative reverse(More)
OBJECTIVE To explore the therapeutic efficacy for patients aged over 70 years with acute myeloid leukemia(non-APL). METHODS Clinical data of 19 acute myeloid leukemia patients aged over 70 years admitted in our hospital from March 2006 to April 2016 years were analyzed retrospectively. Among them 15 patients received priming regimen and 4 patients(More)
To explore the effects of arsenic trioxide on multiple myeloma (MM) cell line KM(3) and its possible mechanism, cell viability was counted by trypan-blue exclusion, apoptosis was detected by morphology and DNA ladder; cell cycle was assayed by flow cytometry (FCM), telomerase activity was determined by semi-quantitative telomeric repeat amplification(More)
OBJECTIVE To analyse the clinical feature and natural course of essential thrombocythemia (ET). METHODS A retrospective analysis was conducted in ET patients treated in our hospital during May 1980 to December 2006. RESULTS Four hundred and thirty eight patients (201 males and 237 females with a median age of 48 years) were diagnosed. Hemorrhage(More)
This study was aimed to investigate the effect of fetal bone marrow-derived mesenchymal stem cells (FBM-MSC) on the development of human Th1 cells. FBM-MSC were isolated, cultured and expanded in vitro. The cells were identified by their phenotype profiles and differential capacity. Human CD4(+) T cells from healthy donors were cultured alone or co-cultured(More)
The aim of this study was to explore the regulatory function of interleukin-6(IL-6) on human Th17 cells. Human peripheral blood CD4(+) T cells were purified from healthy donors by anti-CD4 monoclonal antibody (mAb) conjugated microbeads. The experiment was divided into 2 groups. Test group in which CD4(+) T cells (1 × 10(6)/ml) were stimulated by human(More)
Genome-wide hypomethylation has been confirmed in patients with primary immune thrombocytopenia (ITP). Proteins containing methylcytosine-binding domain (MBD) are involved in promoter methylation as transcriptional repressors and promote the gene-silencing effect of DNA methylation. The purpose of this study was to investigate the methylation pattern of T(More)
