孔子故事大约从唐代开始进入俗文学领域。此后演述孔子故事的俗文学作品不绝如缕。明清时期,孔子故事又借鼓词说唱传播开来。明末贾凫西《太师挚适齐》、清中叶曹汉阁《孔夫子鼓儿词》等,均秉持寓教于乐的动机,说唱孔子故事,传播孔子之道。清末民初,新文化运动兴起,孔子之道遭受很大冲击。一些文人创作的鼓词,形象地揭示了孔子之道在乱世没落的命运。不过,民间鼓词仍在以鲜活可喜的艺术形式继续演绎孔子故事。总的说来,鼓词通过演绎孔子故事、传播孔子之道,有效地扩大了孔子在民间的影响。

Developing green insulation materials has become an important direction for future *** a new environmental insulation liquid,natural ester can effectively delay cellulose insulation polymer *** the mechanism of natural ester delaying the cellulose ageing could promote its application in power *** this study,based on the accelerated thermal ageing of pressboard immersed in natural ester and 25#mineral oil at 120°C for 221 days,the thermal ageing rate and the levelling off degree of polymerisation(LODP)for two kinds of oil-impregnated pressboards were *** molecular level mechanism of natural ester delaying cellulose degradation and keeping higher LODP value was proposed using molecular dynamics *** the early stage of thermal ageing,cellulose with a higher degree of polymerisation(DP)can form many hydrogen bonds with hydronium ions,and their binding energy is stronger,which can accelerate the acid hydrolysis of cellulose,causing the DP of pressboard immersed in natural ester and mineral oil to decrease *** the breaking of the cellulose molecular chain,the number of hydrogen bonds and binding energy between cellulose and hydronium ions becomes smaller and the thermal ageing rate decreases *** the end stage of ageing,it is difficult for the hydronium ions to enter the crystalline cellulose,acid hydrolysis of crystalline cellulose is hard to conduct,leading to the occurrence of the LODP *** degradation rate of cellulose in natural ester is only 50%of that in mineral *** cellulose LODP value in natural ester is over 200 larger than that in mineral *** with the mineral oil-cellulose system,natural ester can form hydrogen bonds with hydronium ions and lead to fewer hydronium ions in cellulose,fewer hydrogen bonds and smaller binding energy between cellulose and hydronium ions,which can reduce the acid hydrolysis reaction of *** study provides a theoretical explanation for

肠道菌群携带的基因被认为是人类的“第二基因组”,肠道菌群也是抗生素耐药基因(ARG)的储存库。肠道菌群组成和功能的紊乱与多种疾病有关。而抗生素的使用打破了肠道菌群原有的稳态,加剧了ARG的传播和扩散,增加了特异性ARG的丰度,对临床治疗造成不良影响。本文就肠道菌群及耐药基因组与抗生素之间的关系做一综述,并对未来研究方向进行展望,以期为肠道耐药基因组的研究提供新思路,同时为临床上合理使用抗生素提供理论依据。

Hybrid rice(Oryza sativa)generally outperforms its inbred parents in yield and stress tolerance,a phenomenon termed heterosis,but the underlying mechanism is not completely ***,we combined transcriptome,proteome,physiological,and heterosis analyses to examine the salt response of super hybrid rice Chaoyou1000(CY1000).In addition to surpassing the mean values for its two parents(mid-parent heterosis),CY1000 exhibited a higher reactive oxygen species scavenging ability than both its parents(over-parent heterosis or heterobeltiosis).Nonadditive expression and allele-specific gene expression assays showed that the glutathione S-transferase gene OsGSTU26 and the amino acid transporter gene OsAAT30 may have major roles in heterosis for salt tolerance,acting in an overdominant fashion in ***,we identified OsWRKY72 as a common transcription factor that binds and regulates OsGSTU26 and *** salt-sensitive phenotypes were associated with the OsWRKY72^(paternal)genotype or the OsAAT30^(maternal)genotype in core rice germplasm ***72^(paternal)specifically repressed the expression of OsGSTU26 under salt stress,leading to salinity sensitivity,while OsWRKY72^(maternal)specifically repressed OsAAT30,resulting in salinity *** results suggest that the OsWRKY72-OsAAT30/OsGSTU26 module may play an important role in heterosis for salt tolerance in an overdominant fashion in CY1000 hybrid rice,providing valuable clues to elucidate the mechanism of heterosis for salinity tolerance in hybrid rice.
