Type 2 diabetes mellitus （T2DM） is a multifaceted metabolic condition characterized by chronic hyperglycemia （elevated blood sugar levels） and insulin resistance （IR）. We have isolated a new homogeneous polysaccharide， LYTP-3， (7.22 × 105Da) with anti-diabetic activity， from large leaf yellow tea （LYT） by biological activity-guided sequential separation and activity evaluation. Using a T2DM mouse model， we demonstrate that oral administration of LYTP-3 can reduce blood lipid levels， alleviate hyperglycemia and glucose tolerance， and inhibit insulin resistance. LYTP-3 ameliorated T2DM treatment by activating the liver X receptor alpha （LXRα）-ATP-binding cassette （ABC） transporter （LXRα-ABCA1/ABCG1） signaling pathway， which is regulated by the gut microbiota. The strain Lachnospiraceae bacterium A4 is potentially the key to this improvement. Additionally， we have solved the molecular structure of LYTP-3 using nuclear magnetic resonance （NMR）， and methylation analyses. The main backbone of LYTP-3 consists of 1，2，4-α-L-Rhap， 1，4-α-D-Galp， 1，6-α-D-Glcp， with branches of 1，4-β-D-Galp， 1，6-β-D-GalpA， 1，3，6-β-D-Manp， 1，2-α-L-Rhap， T-β-Manp， and T-β-Galp. The findings of this study suggest that LYTP-3 may serve as a potential gut microbiota modulator in the treatment of T2DM.

二战后，全球经贸联系日益密切，国际多边经济合作大体经历了初建、大调整、大发展和大变革等四个演进历程。从推进方式看，主要采取了创设正式的国际经济组织、签订区域性贸易经济协定、建立论坛性的组织机构、提出具有排他性的倡议等四种模式。从实施效果看，第一种和第二种对实质性推进国际经济合作的效果最好，也最有影响力；第三种效果次之；第四种目前效果不佳。从演进趋势看，近年来欧美等国通过“小多边”形式推进国际多边经济合作的趋势愈发明显，对我国的影响不容忽视。鉴于此，我们应深刻理解国际多边经济合作动态演进的必然性，科学把握共建“一带一路”多边合作的本质，突出共建“一带一路”与发达国家推进国际多边合作的三大差异，努力推动共建“一带一路”进入高质量发展的新阶段。

我国非通用语高等教育始终以服务国家战略需求为核心要义，具有鲜明的思政导向。当前，高校非通用语课程思政教学实践中面临着多重困境：任课教师对思政育人理念认识不足或存在误区，“两张皮”现象相对严重；教材陈旧滞后，思政元素匮乏，无法满足新时代课程思政的要求；教学方式传统单一，未能充分激发学生的学习兴趣；教学评价机制缺失或不完善，无法准确考量学生在课程思政教学中的思想变化与成长；等等。为了应对如上困境，在教育数字化转型背景下，应充分依托数字化技术全方位推动教师育人理念及能力建设；开发非通用语数字化思政资源库，丰富育人内容；推动教学方式数智化转型，增强教学的创新性与互动性；创设智慧化多元评价机制，科学评估思政成效，从而实现非通用语课程思政的提质增效。

作者： Rui Yu xi Cao chengyang Zhu Qingqing chen Ziyi Yan Binbin Jiang Junjie Mao xianwen Wei Key Laboratory of Electrochemical Clean Energy of Anhui Higher Education Institutes College of Chemistry and Materials ScienceAnhui Normal University Anhui Provincial Key Laboratory of Advanced Catalysis and Energy Materials School of Chemistry and Chemical Engineering Anqing Normal University School of Chemistry and Chemical Engineering Anhui University of Technology

Developing highly efficient and cost-effective electrocatalysts for hydrogen evolution reaction（HER） is grandly challenging in alkaline and alkaline seawater electrolytes. Herein, the asymmetric interfacial active sites with Ru nanoparticles and Ni single atoms in Ru/Ni-N-C were designed through a solvothermal-pyrolysis process. Constructing highly asymmetric interfacial active sites with a strong electron delocalization effect significantly improves HER kinetics. As expected, Ru/Ni-N-C requires low overpotentials with around 20 mV at 10 mA cm-2and robust durability over 48 h in alkaline and alkaline seawater *** at 200 mA cm-2, the overpotentials are close to 100 mV in both above electrolytes for Ru/Ni-N-C. Density function theory calculation results suggest that the asymmetric interface between Ru nanoparticle and Ni-N-C could accelerate the dissociation of water molecules and modulate the hydrogen species, consequently improving the HER performances. This work opens a unique approach for constructing advanced materials for energy conversion.
