These studies support the hypothesis that ih might arise from invading angioblasts or placental cells and these epcs excessively secrete vascular growth factors , resulting in an increasing favorable local environment for endothelial proliferation , and contribute to aberrant endothelial growth in ih 认为可能的发病机制是调控细胞增殖及分化的基因区发生突变的内皮祖细胞过度分泌血管形成因子，造成局部微环境血管形成抑制的失衡，内皮细胞迅速增殖而形成婴幼儿血管瘤。
Based on the applications in cell marking of fluorescent probe , the developing trends are described including approaches and methods of increasing the compatibility of fluorescent probe with bodies tissue , the validity for labeling towards the aberrant cell , improving the sensitivity and reducing toxicity of fluorescent probe 并针对目前荧光染料探针分子的应用现状，分析了未来的发展趋势，包括增强荧光染料探针分子与人体组织的相容性、靶向性，提高其灵敏度，降低毒性等的方法和途径。
Abstract : through analysing systematically the conditions of engineerin g geology and hydrogeology , the regimes of groundwater level and data of deep wells , the p aleorelief , and the groundwater levels measured during the periods of foundation investigation of each existing building , the aberrant cause of groundwater level at yangfangdian and its vicinity was derived , and the approximate scope of grou ndwater level anomalies in the above - mentioned area in march , 1999 was obtained by calculation 文摘:该文全面系统地分析了羊坊店及其附近地区的工程地质和水文地质条件、地下水位动态、深井资料、古地形及现有建筑勘探时实测水位资料，指出了羊坊店及其附近地区地下水位异常的原因，并通过计算得出了1999年3月份该地区地下水位异常的大致范围。
Here we show that seeral of these targets sensitize lung cancer cells to paclitaxel concentrations 1 , 000 - fold lower than otherwise required for a significant response , and we identify mechanistic relationships between cancer - associated aberrant gene expression programmes and the basic cellular machinery required for robust mitotic progression 在研究中我们结果显示这些靶目标使得肺癌细胞对于1000倍浓度的紫杉醇敏感性低于另外一种要求的显著反应，由此我们确定了在肿瘤相关异常基因表达过程中和简单的细胞机制中强大有丝分裂进程两者间的机制关系。
