The synthesis of O-, C-, and N-glycoconjugates has continuously been an attractive research subject due to the growing biological importance of various glycoconjugates. In recent years, by careful changing the glycosylation reaction conditions, especially the amount of activators and the preactivation temperature, （p-Tol）2SO/Tf2O preactivition strategy was developed as a general method for the synthesis of various 0-, C-, and N-glycoconjugates, including related biological active glycoconjugates, such as nucleosides and antigen Lewisa etc. High yields and excellent stereoselectivities were obtained even without the anchimeric assistance at the adjacent position of anomeric carbon. In this review, we predominantly make a review on the progress of the （p-Tol）2SO/Tf2O preactivition strategy from O-, C-sialylation to general O-, N-glvcosvlation.

目的分析苯磺酸瑞马唑仑用于老年全身麻醉腰椎手术患者维持期,对苏醒质量及认知功能的影响。方法选取2021年9月至2023年4月于合肥京东方医院择期行全身麻醉腰椎手术的老年患者60例,采用随机数字表法分为丙泊酚组(n=30)和瑞马唑仑组(n=30)。丙泊酚组泵注瑞芬太尼+丙泊酚维持麻醉,瑞马唑仑组泵注瑞芬太尼+瑞马唑仑维持麻醉。比较两组不同时间点的麻醉相关指标及术后48 h内不良反应发生情况。结果瑞马唑仑组T2、T3时间点平均动脉压(MAP)和心率(HR)、拔管后Ramsay镇静评分及术后24 h、48 h MoCA评分和MMSE评分均高于丙泊酚组(P<0.05)。瑞马唑仑组苏醒时间、拔管时间均短于丙泊酚组,血管活性药物使用率、术后48 h内低血压和注射痛发生率均低于丙泊酚组(P<0.05)。结论相较于丙泊酚,苯磺酸瑞马唑仑用于老年全身麻醉腰椎手术患者维持期更加有利于稳定血流动力学,提高镇静效果和苏醒质量,对患者术后认知功能的影响更小,同时减少不良反应的发生。

A three-dimensional flexible organic framework FOF-1 has been synthesized from the condensation of a tetratopic acylhydrazine and a rigid 4,4-diphenyl-4,4-bipyridinium dialdehyde in water through the quantitative formation of hydrazone bond. FOF-1 is further applied to construct a polycatenane framework FOF-pc-1 through the quantitative cucurbit[7]uril encapsulation for the diphenylbipyridinium subunits of the framework by making use of the dynamic nature of the hydrazone bond in water. The bipyridinium subunits in both frameworks can be reduced their radical cation counterparts to produce conjugated radical cation-linked dynamic organic frameworks rc-FOF-1 or rc-FOF-pc-1. Polycatenation is revealed to enhance the stability of the dynamic frameworks in water, whereas depolycatenation can be reached for both FOF-pc-1 and rc-FOF-pc-1 by using a ferrocene guest to form a more stable complex with CB[7].

Method development has always been and will continue to be a core driving force of microbiome science, In this perspective, we argue that in the next decade, method development in microbiome analysis will be driven by three key changes in both ways of thinking and technological platforms： ① a shift from dissecting microbiota structure by sequencing to tracking microbiota state, function, and intercellular interaction via imaging; ② a shift from interrogating a consortium or population of cells to probing individual cells; and ③a shift from microbiome data analysis to microbiome data science. Some of the recent methoddevelopment efforts by Chinese microbiome scientists and their international collaborators that underlie these technological trends are highlighted here. It is our belief that the China Microbiome Initiative has the opportunity to deliver outstanding ＂Made-in-China＂ tools to the international research community, by building an ambitious, competitive, and collaborative program at the forefront of method development for microbiome science.

The miR-145was down-regulated in the LPS-induced ARDS lung, and mitochondrial dysfunction was observedin alveolar epithelial cells, most obviously at 72 hours after LPS. TargetScan and miRDB databaseswere used to predict the target genes of miR-145. A total of 428 overlapping genes were identifi ed,seven genes were associated with mitochondrial function, and Ogt, Camk2d, Slc8a3, and Slc25a25were verifi ed. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were enriched in themitogen-activated protein kinase (MAPK) signaling pathway, and Gene Ontology (GO) biologicalprocess was mainly enriched in signal transduction and transcription ***: The miR-145 is down-regulated in LPS-induced ARDS, and affects itsdownstream genes targeting mitochondrial functions.

Using the suppression subtractive hybridization method, we isolated five gene families, including proline-rich proteins (PRPs), arabinogalactan proteins (AGPs), expansins, tubulins and lipid transfer proteins (LTPs), from fast elongating cotton fiber cells. Expression profile analysis using cDNA array technology showed that most of these gene families were highly expressed during early cotton fiber developmental stages (0-20 days post anthesis, DPA). Many transcripts accumulated over 50-fold in 10 DPA fiber cells than in 0 DPA samples. The entire gene family -AGP, together with 20 individual members in other 4 gene families, are reported in cotton for the first time. Accumulation of cell wall proteins, wall loosening enzymes, microtubules and lipid transfer proteins may contribute directly to the elongation and development of fiber cells.
