The occurrence and development of lung cancer was a complex multi-factorial multi-step biological process,and apoptosis imbalance was closely related to it.puma was a new member of the apoptosis-related genes that was initially identified in 2001,and was the downstream garget gene of p53,and through p53-dependent and non-dependent pathway to promote apoptosis.

肺癌的发生发展是一多因子、多步骤的复杂生物学过程,与凋亡失衡有着密切的关系。puma是2001年新发现的凋亡相关基因领域新成员之一,是p53的下游靶基因,可通过p53依赖和p53非依赖途径促进细胞凋亡,其介导的凋亡机制在肿瘤包括肺癌发展的多阶段中都起到重要的作用。

Metazoan transcription regulation occurs through the concerted action of multiple transcription factors that bind co-operatively to cis-regulatory modules.

多细胞动物的转录调控通过协同的结合到顺式调控元件的多个转录因子的协同作用而发生。

Gabor-ring is often used in texture feature extraction, but it is based on the assumption that texture is narrowband signal and can not applied to most actual textured images that have more than one center frequency in power spectrum. To overcome the limitation of existing method, an improved method is proposed. According to this method, Gabor filters are constructed in accordance with the spectrum feature vector of texture, and a relaxation parameter is used to determine the effect of difference filters so as to integrate the frequencies and phases into the process of extraction.

Gabor环(即在频率域成环形分布的Gabor滤波器组)常被用于提取图像纹理特征,但它是以"纹理是窄带信号"为基础的,实际的纹理图像并不能很好地满足"窄带信号"的假设,用一个中心频率来描述一种纹理对能量集中在多个频率点的纹理图像往往不能取得理想的效果,而根据频谱特征值向量构造Gabor环的改进方法,通过松弛因子的加入改变不同滤波器的作用强度,综合考虑了多频率多相位对纹理特征提取的影响。

Third,the supernal vitality and regenerative ability of primitive myth.

河南神话的基本特征主要表现为:多文化因子的融合;多神话与传说的并存;原生神话超强的生命力与再生力;地域性与超地域性;神话与传说的相互生成;神话演变过程中的非逻辑性与超时代性。

Diopter, corneal curvature, depth of anterior chamber and the axial length of the eyes were measured. We calculated the concordance of hyperopia, intrapair correlation coefficient and heritability index of monozygous and dizygous twins.

调查了同卵和异卵双生子的屈光度、角膜曲率半径、前房深度、眼轴长度,计算了远视的一致率,同卵和异卵双生子的组内相关系数及遗传指数等项目,证实远视眼是一种多因子遗传病,它的发生除了与多个遗传性状如角膜曲率半径、前房深度、眼轴长度等有关外,还与环境因素有关。

In this study, the methodology of linear structural rela- tionship model of latent variable has been studied which is the first time in China. Some extended conclusions have been come up to, such as multi-factor congeneric measure model, the reliability of measurable variable and its hy- pothesis test, the relation between standardized solution and unstandardized solution, multidimensional path model with measure errors, and multilevel model of latent vari- able. Some examples have been shown to help apply these results in practice, such as the analyses of the children growth-development data, the bone density data and the health resources data by means of latent variable model. Not only have new explanations for these data been achieved, but also powerful patterns for applying the theoretical methods in medical sciences and other fields.
