Prolonged chronic phase in chronic myelogenous leukemia after homoharringtonine therapy.

Background: Homoharringtonine (HHT) is effective in treating late stage chronic myelogenous leukaemia (CML), but little is known about long term maintenance during complete cytogenetic response. Long term efficacy and toxicity profiles of low dose HHT were evaluated in this study.

Methods: One hundred and six patients with CML received 1.

[Influence of methylprednisolone on cell component of donor graft and on H-2 haploidentical hematopoietic stem cell transplantation in mice].

Objective: To explore the influence of methylprednisolone (MP) on cellular component in donor graft and on H-2 haploidentical hematopoietic stem cell transplantation (HSCT) in mice.

Methods: A murine model of H-2 haploidentical HSCT was established by using of c57BL/6J male mouse as donor and (c57BL/6J x LB/C) F1 female mouse as recipient. The donor mouse received peripheral-blood (PB) progenitor cells mobilization regimens consisted of recombinant human granulocyte colony-stimulating factor (rhGCSF) alone (control group) or combined with MP in dose of 2 mg/kg daily [small-dose (SD) group], 10 mg/kg daily [middle-dose (MD) group], and 50 mg/kg daily [large-dose (LD) group] respectively.

[Antisperm-antibodies induced by testicular torsion and its influence on testicular function].

Objective: To investigate the changes of antisperm antibodies (AsAb), sexual hormones, and inhibin B (INH B) in patients before and after testicular torsion, as well as the effects of these factors on testicular function and reproduction.

Methods: Ten patients with single acute testicular torsion (left side 9 and right side 1), aged 16-45 years (19.6 on average), disease course of 3-6 days (averaging 4.

Mycophenolic acid inhibits SLE-associated cytokine expression and promotes apoptosis of peripheral blood mononuclear cells from patients with systemic lupus erythematosus.

Aim: To investigate the effect of the novel immunosuppressant mycophenolic acid (MPA) on cytokine production and apoptosis of the peripheral blood mononuclear cells (PBMC) of patients with systemic lupus erythematosus (SLE).

Methods: The levels of IL-10, IL-12, IFN-gamma, sFas and sFasL in the supernatants of cultured PBMC from 41 SLE patients was determined by the ABC-ELISA method. The percentage of IFN-gamma(+)IL-10(-), IFN-gamma(-)IL-10(+), and IFN-gamma(+)IL-10(+) subsets in CD4+ cells were detected by three-color flow cytometry.
