水被认为是 2 1世纪的战略性资源。在国际流域中 ,对跨国水资源的管理提出一个新的框架以解决由国际河流引发的冲突是非常重要的。本文针对国际河流引起的争端作了一个总体描述 ,焦点集中在欧盟成员国上。国际以至全球环境管理的概念发展迅速 ,这对国际社会在国际河流管理上所持的态度产生了重大的影响。建立这些新概念、原则及机构有助于将国际河流管理中所关注的环境方面的复杂问题具体化。有关水资源管理的全球性协议应该在一个共同的总框架下提出 ,同时还要在计划、管理、执行方面写出明确具体的协议。这对于达到社会、环境、技术、法律和风俗习惯之间的平衡发展及充分结合是非常重要的。目前联合国已经提出了一个新的非航运水域水的利用公约 ,这是在解决国际争端长期而艰苦的过程中取得的一个显著成果。

9号染色体四倍体患者的先天性膈疝1例

世界核心医学期刊文摘（儿科学分册） 2006年第4期2卷 39-39页

Tetrasomy of the short arm of chromosome 9 constitutes a rare condition resulting in a well clinically recognized syndrome. In our case, in addition to the characteristic phenotype at birth, the existence of a hernia-type Bochdalek diaphragmatic defect was found. Cytogenetic analysis revealed a nonmosaic case of an isochromosome of the entire short arm of chromosome 9 with no involvement of the heterochromatic region of the long arm: 47, XX, + i (9p). Because chromosome 9 contains several gene locus for enzymes and receptors of the retinoid pathway, this case potentially contributes to retinoid hypothesis in the etiology of congenital diaphragmatic hernia.
