以云南四种典型材用丛生竹（龙竹、甜龙竹、黄竹和油勒竹）宏观构造、组织结构、主要物理力学性质和化学组份等竹材主要生物学特性的研究分析结果为依据，提出了竹大片刨花板的结构、制板工艺和设备与原料竹材生物学特性之间应有的适应性关系。继而，通过实验室系列化试验和工厂试生产，确定了竹大片刨花板的应有性能和最佳工艺条件包括竹大片刨花的最佳质量指标及其最佳制备条件。

Down-regulated expression of PTEN and up-regulated expression of VEGF〓 were considered as two important events in tumorigenesis of ovarian cancer and could act as molecular markers to indicate the pathobiological behaviors of ovarian cancer. Decreased PTEN expression and increased VEGF〓 expression were closely associated with tumorigenesis and pathobiological behaviors of ovarian endometrioid and serous cancer respectively. Reduced expression of PTEN gene might be involved in carcinogenesis and progression of ovarian cancer by up-regulating the VEGF〓 expression to enhance angiogenesis.

在卵巢癌组织中PTEN基因mRNA表达下调和VEGF〓基因mRNA表达上调是卵巢癌发生的重要分子事件，可作为反映卵巢癌病理生物学行为的指标，且分别与卵巢内膜样癌和浆液性囊腺癌的发生和病理生物学行为关系密切；PTEN基因mRNA表达降低可能通过上调VEGF〓基因mRNA表达促进新生血管形成，进而参与卵巢癌的发生和侵袭。

Furthermore, preliminary work also performed to examine whether PI3K/AKT signal transduction pathway was activated in the process of refractory leukemia development. Materials and methods An immortalized human bone marrow stromal cell line, HS-5, was introduced to establish a bi-phase culture system for the cultivation of B-lineage precursor leukemia cells. ELISA and RT-PCR were used to investigate the expression of VEGF and its receptors in the leukemia cell lines and primary childhood leukemia cells in different treated groups. Flow cytometory method and immunofluorescent staining were employed to examine the apoptosis signals both in the VP16 treated and untreated leukemia cells. Western blot was utilized to explore the PI3K/AKT activated status in the drug induced or uninduced leukemia cells and lymphocytes from healthy donors.
