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.

结果：VPA能显著抑制Kasumi-1细胞的增殖，且呈剂量和时间依赖性，VPA处理Kasumi-1细胞72h时的半数抑制浓度(IC50)为2.33 mmol/L；VPA处理后，细胞周期检测G0/G1期细胞比例逐渐增高；VPA能诱导髓系分化抗原CD11b表达水平的阳性率升高，呈时间及剂量依赖性；VPA能诱导Kasumi-1细胞凋亡，Kasumi-l细胞经VPA3 mmol/L处理72h后，出现典型的凋亡细胞所具有的梯形DNA条带。

Viral infection of the host cell may be switched on by the specific and stable combination of one or several viral envelope protein with one or several glycoprotein receptors available on the cell membrane, which is followed by viral pinocytosis or viral fusion with cell membrance, viral deenvelope, viral particle movement from cytoplasm towards nucleus and the viral gene passage.

病毒感染细胞可能是通过一个或几个病毒包膜蛋白与一个或多个细胞膜上的糖蛋白受体特异稳定地结合而启动，通过病毒胞饮作用或者病毒与胞膜融合、病毒脱包膜、病毒粒子从胞浆到胞核的运动和病毒基因通过核膜的传代将会发生；但参与这些动力过程相关的病毒、细胞结构和生化因子仍不清楚。
