RESULTS: The average dose of venlafaxine was (196±s 48) mgd^(-1), the average effective time was (8±3) d, and the effective rate was 68%.

Results: The proliferation of Kasumi-l cell was obviously inhibited by VPA on dose- and time-dependent manner. The IC50 was 2.33 mmol/L treated with VPA for 72 h. Incubation with VPA, the cell ratio at G0/C1 phase increased. VPA induced myeloid cell differentiation antigen CD11b to increase with a time-and dose-dependent way and caused apoptosis. Wright's staining and light microscope were used to show the morphology of partial differentiation and obvious apoptosis with 3 mmol/L VPA for 72 hours. The typical DNA ladder of apoptosis characteristic was observed with DNA gel electrophoresis.
