[The prevalence of Th17 cells in patients with acute myeloid leukemia].

Objective: To investigate the proportion of Th17 cells in the peripheral blood of the patients with acute myeloid leukemia (AML) and evaluate the potential association of Th17 cells with AML.

Methods: The cytokines IL-17 and TGF-β1 in the peripheral blood of AML patients before therapy (group 1), AML patients in complete remission (AML-CR, group 2) and healthy donors (group 3) were measured by enzyme-linked immunosorbent assay (ELISA). The proportion of Th17 cells of each group was evaluated by flow cytometry.

[Magnetic resonance imaging and pathological evaluation of vacuum sealing drainage efficacy of early treated limb gunshot].

Objective: Gunshot wound spreads to the surrounding tissues and organs, it is difficult to debride and easy to infect. The conventional treatment is thorough, extensive debridement, fully open drainage, which often causes normal tissue damage and complications. To evaluate the effectiveness of vacuum sealing drainage (VSD) treating the penetrating wound in porcine extremity by MRI and pathological methods so as to provide theoretical basis for future clinical use.

[In vitro cytokines-induced differentiation in mononuclear cell derived dendritic cells from chronic myeloid leukemia].

The purpose of this study was to investigate the mechanism of effects of interferon-alpha (IFN-alpha) on chronic myeloid leukemia (CML). Bone marrow mononuclear cells (BMMNC) were obtained from heparinized blood of CML patients by Ficoll-Paque density gradient centrifugation. The expressions of CD1a, CD83, CD86, HLA-ABC, HLA-DR and CD54 on DC induced by IFN-alpha + GM-CSF, IFN-alpha + GM-CSF+IL-4 and IL-4 + GM-CSF for 7 days in vitro were assayed by flow cytometry.

Analysis of dermatomycoses in Lanzhou district of northwestern China.

The skin mycoses, perticularly dermatophytoses, in Lanzhou district, Northwestern China, was investigated during July 2002-June 2003. The specimens from patients suspected of having dermatomycoses were examined microscopically in KOH preparations and cultured on Sabouraud dextrose agar (SDA). Among 1443 suspected cases, 594 were KOH positive and 221 cultures of fungi were isolated.
