Objective: To evaluate the efficacy of second-generation tyrosine kinase inhibitor (TKI) in treating chronic myeloid leukemia (CML).
Methods: A total of 97 patients with CML were enrolled. The patients were treated with TKI and monitored with complete blood count, cytogenetic and molecular indicators during the course of therapy.
In an attempt to establish the advantages of fluorescence in situ hybridization (FISH) studies over conventional cytogenetic (CC) analysis, a total of 2302 de novo MDS patients from 31 Chinese institutions were prospectively selected in the present study for both CC and standardized FISH analysis for +8, -7/7q-, -5/5q-, 20q- and-Y chromosomal abnormalities. CC analysis was successful in 94.0% of the patients; of these patients, 35.

Objective: To evaluate the effects of tyrosine kinase inhibitors (TKI) in the treatment of chronic myeloid leukemia.
Methods: There were total 655 cases of chronic myeloid leukemia treated in one single-institution enrolled in this study. The dosage of TKI Imatinib was 400 mg/d for chronic phase, 600 mg/d for accelerated and blast phase respectively.
Recent data indicates that nucleoside/nucleotide analogue (NUC) is effective in preventing and controlling hepatitis B virus (HBV) reactivation in HBV-carrying cancer patients who undergo chemotherapy, but the ideal antiviral agent and optimal application protocol still needs to be determined. Meanwhile, it is uncertain whether those with past HBV infection require antiviral prophylaxis during chemotherapy. This report retrospectively analyzed non-Hodgkin's lymphoma (NHL) patients seen from January, 2004 to June, 2009 in West China Hospital.

Objective: To measure the levels of hormones in chronic myelogenous leukemia (CML) patients receiving imatinib mesylate (IM) and evaluate the effects of IM on endocrine system.
Methods: 69 patients with CML while taking IM were enrolled and a total of 86 peripheral blood samples were detected. The levels of total triiodothyronine (TT3), total tetraiodothyronine (TT4), thyroid stimulating hormone (TSH), testosterone, progesterone, estradiol (E2), plasma total cortisol (PTC) at 8:00-10:00 am measured.

The purpose of this study was to detect the minimal residual disease (MRD) in peripheral blood of newly diagnosed patients with acute myeloid leukemia (AML) on day 8 of induction chemotherapy and analyze the correlation between day 8 MRD (D8RD) and therapeutic effectiveness. 29 adult patients (13 males and 16 females, aged 16 - 75 years, median 41 years) with AML diagnosed and treated in West China Hospital from September 2009 to June 2010 were analyzed and followed up in the study. The leukemia-associated aberrant immunophenotype (LAIP) of all the patients were detected by multiparameter flow cytometry (FCM) before therapy.

In this study we compared results of flow cytometric immunophenotype (FCI) with cytomorphology, histopathology and clinical findings in a series of patients with NK cell neoplasms with peripheral blood and/or bone marrow involvement, and the FCI of neoplastic and normal NK cells were compared. Retrospective data and specimens (bone marrow aspiration or peripheral blood) from 71 cases of NK cell neoplasms were obtained.

The aim of study was to investigate the immunophenotype characteristics and prognosis of acute leukemia patients with cross-expressing lymphoid and myeloid lineage-associated antigens. The immunophenotypes of leukemic cells were examined by using flow cytometry. All patients were classified into several groups according to FAB subtypes and immunophenotyping.

Objective: To evaluate the value of flow cytometric immunophenotyping of cerebrospinal fluid (CSF) cells in the diagnosis of central nervous system leukemia.
Methods: Ninety two CSF samples were analyzed with 4-color flow cytometry. Antibody panles CD19/CD34/CD3/CD45, CD117/CD34/CD5/CD45, CD7/CD34/ CD19/CD45, CD7/CD3/HLA-DR/CD45, CD20/CD10/CD3/CD45, and anti-g/anti-lambda/CD19/CD45 were used in determining cell composition and detecting abnormal cells.
Objective: To explore demographic characteristics, current diagnosis and treatment patterns of chronic myelogenous leukemia (CML) patients in China.
Methods: Data of hospitalized CML patients in 2005 whole year and outpatient information (July 1 through September 30, 2006) from 15 hospitals throughout China were analyzed.
Results: A total of 1824 CML cases were analyzed, including 722 inpatients and 1102 outpatients.

Objective: To explore the correlation between hOCT1 polymorphism and imatinib mesylate (IM) effectiveness in chronic myelogenous leukemia(CML) patients, and to provide for the clinical individual personalized therapy.
Methods: Fifty-three CML and 23 non-CML patients were enrolled in this study. Blood or bone marrow samples were collected.

Objective: To measure the expression of hOCT1 gene in patients with Chronic Myelogeneous Leukemia (CML) and to explore its role in the progress of the disease and responding to Imatinib Mesylate (IM) treatment.
Methods: Sixty three peripheral blood or bone marrow samples were taken from 30 patients with CML (20 in chronic phase, 10 in advanced phase). The samples were divided into two groups: responding (optimal and suboptimal) and non-responding according to effectiveness of the IM treatment.

Objective: To explore the MMP-9 expression profile in peritoneal inflammatory macrophages and granulocytes in Mip-1alpha-, CCR1- and CCR5-deficient mice.
Methods: In sodium thioglycolate-induced murine peritonitis models, peritoneal macrophages and granulocytes were harvested, identified and purified from WT mice and Mip-1alpha-, CCR1-, CCR5-deficient mice. The RT-PCR was applied to evaluate the expression of MMP-9 in macrophages and granulocytes of different group of mice.

This study was purposed to investigate the changes in quantum and function of gammadelta T cell subsets, and to explore its significance in pathogenesis of acquired pure red cell aplastic anemia (A-PRCA). Eleven patients were diagnosed as A-PRCA based on bone marrow smear and biopsy, and were treated with cyclosporine A and glucosidorum tripterygll totorum. The flow cytometry technique was used for analyses of T cells subsets and gammadelta T cells.

To explore the effect of arsenic trioxide (As2O3) on growth and secretion of interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) of bone marrow stroma cells (BMSC) from the patients with multiple myeloma (MM). Specimens of bone marrow aspiration from MM patients were used to establish BMSC cultures. BMSC and human MM cell line CZ-1 were cultured together or alone in the absence or presence of As2O3 at various concentrations (1-20.

To investigate the immune regulatory effects of human bone marrow mesenchymal stem cells on alloantigen T lymphocyte in vitro, human MSCs were isolated and expanded from bone marrow cells, and identified with cell morphology, and the phenotypes were assessed by immunohistochemistry and flow cytometry. As the stimulation factor of T lymphocytes proliferation, either PHA or dendritic cells isolated from cord blood were cocultured with CD2(+) T lymphocytes from peripheral blood mononuclear cells by magnetic beads with or without MSC in 96-well plats for seven days. T cell proliferation was assessed by [(3)H]-thymidine incorporation using a liquid scintillation counter.

Immune mediated suppression of hematopoiesis has been considered as one of the most important mechanisms leading to pancytopenia in myelodysplastic syndromes. This research was aimed at evaluating immune state of the MDS patients, analyzing the peripheral blood T cell subsets and CD3zeta chain expression and searching the possible reasons of hematopoietic disorders in 11 cases of MDS. Peripheral blood mononuclear cells were collected from 11 patients whose diagnosis was confirmed according to the new WHO diagnostic criteria.
