过去一百多年,各国对肿瘤浩浩荡荡的研究并没有取得突破性进展,就如Leaf^([1])在2004年Fortune所提到:"Why We're Losing the War on Cancer——and How to Win it?”。近10多年来,基因组学、功能基因组学、高通量生物芯片、新一代测序及生物信息学、高通量RNAi等前沿技术的迅猛发展,国际癌症基因组(ICGC)项目的启动,使得我们将有机会看清肿瘤的全貌,一直在不断重演的“盲人摸象”式研究的历史有望结束。展开更多

However,few studies have addressed the mechanism by which elevated CO_2 may affect the growth of medicinal plants. Isatis indigotica Fortune is a widely used Chinese medicinal herb with multiple pharmacological properties. To investigate the physiological mechanism of I.indigotica response to elevated [CO_2], plants were grown at either ambient [CO_2](385 μmol mol^(-1)) or elevated [CO_2] (590 μmol mol^(-1)) in an open-top chamber (OTC)experimental facility in North China. A significant reduction in transpiration rate (T_r) and stomatal conductance (g_s) and a large increase in water-use efficiency contributed to an increase in net photosynthetic rate (Pn) under elevated [CO_2] 76 days after sowing. Leaf non-photochemical quenching (NPQ) was decreased, so that more energy was used in effective quantum yield of PSII photochemistry (Φ_(PSⅡ)) under elevated [CO_2]. High ΦPSII,meaning high electron transfer efficiency, also increased Pn. The [CO_2]-induced increase in photosynthesis significantly increased biomass by 36.8%. Amounts of metabolic compounds involved in sucrose metabolism, pyrimidine metabolism, flavonoid biosynthesis, and other processes in leaves were reduced under elevated [CO_2]. These results showed that the fertilization effect of elevated [CO_2] is conducive to increasing dry weight but not secondary metabolism in I. indigotica.展开更多

The purposes of discussing the ethic of crop resources are to protect the ecology and safety of crops, to gain sustainable development, furthermore, to choose and form the production structure that is favorable to saving crop resources and protecting the ecology of crops. Plant genetic engineering is the technology of molecule breeding of rearrangement of inheritance materials at the level of molecule directionally, of improving plant properties and of breeding high quality and yield varieties of crops. The prominent effects of the technology on the crop ecological system are human subjective factors increasing as well as violating the nature and intensifying the conflict between human being and nature. Therefore, in plant genetic engineering, crop resources exploitation should follow certain ethic principles. Under the theory of ethics of natural resources, by the means of biologinal-statistics, the author systematically analyzed the possible model of crop resources transfer between generations as well as the transfer mode of magnitude of real materials and magnitude of value.展开更多

She writes plenty of poems with unique perspectives, bold and innovative themes and various writing techniques. And her poetry possesses incomparable originality. Her close attention is often devoted to those seemingly trifling and subtle things. This paper is to explore her four poems which manifest she is always morally pure and indifferent to fame and fortune. It can be seen that self-cultivation is far more significant than physical achievement.展开更多
