小学生诗词楹联经典诵读开展方式的探究

诗词楹联是传统文化中的重要组成部分,读起来朗朗上口。诗词的历史非常悠久,从商周时期的《诗经》到唐诗宋词再到近代诗词,留给学生的是丰富的文化遗产。而楹联的历史也非常悠久,广义的楹联可以追溯到《诗经》时期,因为诗经中有很多对仗的语句,例如“昔我往矣,杨柳依依;今我来思,雨雪霏霏”等。狭义的楹联从五代后蜀主孟昶开始就已经非常普遍了。而到了明清时期,对对联的风俗非常盛行,对对联成为文人士大夫们重要的娱乐方式。可以说,诗词和楹联以其短小精悍的特点成为了古代流传最广的文学形式之一。因此,小学阶段朗诵诗词楹联是对传统文化的有力传承和发扬。

Understanding divergent domestication traits from the whole-genome sequencing of swamp- and river-buffalo populations

Domesticated buffaloes have been integral to rice-paddy agro-ecosystems for millennia, yet relatively little is known about the buffalo genomics. Here, we sequenced and assembled reference genomes for both swamp and river buffaloes and we re-sequenced 230 individuals (132 swamp buffaloes and 98 river buffaloes) sampled from across Asia and Europe. Beyond the many actionable insights that our study revealed about the domestication, basic physiology and breeding of buffalo, we made the striking discovery that the divergent domestication traits between swamp and river buffaloes can be explained with recent selections of genes on social behavior, digestion metabolism, strengths and milk production.     

A stage-specific cell-manipulation platform for inducing endothelialization on demand

Endothelialization is of great significance for vascular remodeling, as well as for the success of implanted vascular grafts/stents in cardiovascular disease treatment. However, desirable endothelialization on synthetic biomaterials remains greatly challenging owing to extreme difficulty in offering dynamic guidance on endothelial cell (EC) functions resembling the native extracellular matrix-mediated effects. Here, we demonstrate a bilayer platform with near-infrared-triggered transformable topographies, which can alter the geometries and functions of human ECs by tunable topographical cues in a remote-controlled manner, yet cause no damage to the cell viability. The migration and the adhesion/spreading of human ECs are respectively promoted by the temporary anisotropic and permanent isotropic topographies of the platform in turn, which appropriately meet the requirements of stage-specific EC manipulation for endothelialization. In addition to the potential of promoting the development of a new generation of vascular grafts/stents enabling rapid endothelialization, this stage-specific cell-manipulation platform also holds promise in various biomedical fields, since the needs for stepwise control over different cell functions are common in wound healing and various tissue-regeneration processes.
