Plasma treatment is a powerful tool to tune the properties of two-dimensional materials. Previous studies have utilized various plasma treatments on two-dimensional materials. We find a new effect of plasma treatment. After controlled oxygen-plasma treatment on field-effect transistors based on two-dimensional SnSe2, the capacitive coupling between the silicon back gate and the channel through the 300 nm SiO2 dielectric can be dramatically enhanced by about two orders of magnitude(from 11 n F/cm^2 to 880 nF/cm^2), reaching good efficiency of ionliquid gating. At the same time, plasma treated devices show large hysteresis in the gate sweep demonstrating memory behavior. We reveal that this spontaneous ion gating and hysteresis are achieved with the assistance of a thin layer of water film automatically formed on the sample surface with water molecules from the ambient air, due to the change in hydrophilicity of the plasma treated samples. The water film acts as the ion liquid to couple the back gate and the channel. Thanks to the rich carrier dynamics in plasma-treated two-dimensional transistors, synaptic functions are realized to demonstrate short-and long-term memories in a single device. This work provides a new perspective on the effects of plasma treatment and a facile route for realizing neuromorphic devices.

Dwarfing breeding of wheat in the world is confined to the exploitation of recessive dwarfing sources. None of the dominant dwarfing sources discovered in common wheat (Triticum aestivum L.) has found wide exploitation in wheat breeding due to the extreme dwarfness of their plants (2055 cm). We found in our work that some stable mutant lines with their plant height enhanced to different extents could be obtained in large populations derived from the stock seeds of the dominant dwarfing sources Aibian1 carrying Rht10 on 4DS and being 2055 cm tall and Aisu2 carrying Rht3 on 4BS and being 55 cm tall, or from their descendants of induced mutation treatments, or from the segregating descendants of their crosses with mid- or tall-statured genotypes. Subsequently, we studied these mutation-derived lines differing in plant height with near isogenic lines and observed that the character of their enhanced plant height bred true, each carrying a semi-dominant dwarfing gene for a definite height and that as the plant height of the mutation-derived lines increased, the yield-contributing characters of their near isogenic lines were significantly improved. When test crosses with marker genes and physiological and biochemical genetic marker tests were performed to re-localize the semi-dominant dwarfing genes carried by the mutation-derived lines, it was confirmed that they shared common loci with Rht10 and Rht3 and that they were all mutation-derived multiple alleles. It is thus speculated that dominant dwarfing genes are of 'multi-allelic polymorphism'. In other words, dominant dwarfing genes, which are ultra-dwarfing, are liable to develop by mutation into a group of multiple alleles with plant height enhanced to different extents and some may have a height close to the ideal plant height for wheat breeding. Therefore, these results offer a fundamentally new approach for the exploitation of dominant dwarfing sources in wheat breeding.

基本养老保险中的低收入参保者对养老保险待遇依赖性更强。为研究基本养老保险是否能够为低收入者提供适度的保障水平问题,本文借鉴经济合作与发展组织(Organization for Economic Co-operation and Development, OECD)养老保险体系“三层次”理论厘清了我国基本养老保险制度功能定位,即城乡居民基本养老保险和城镇职工基本养老保险在养老保险体系中承担的功能分别是缓解贫困与消费平滑,并据此分别设定了两种制度待遇适度水平的上限与下限;利用2019年CHFS微观数据以及2006~2023年《中国统计年鉴》数据,模拟测算了我国基本养老保险低收入参保者的替代率分布状况,并结合适度区间分析了适度水平,计算了低收入参保者的缴费负担。研究发现:城乡居民基本养老保险低收入参保者替代率水平普遍低于适度标准;城镇职工基本养老保险低收入参保者替代率水平相对较高,但缴费负担过重。为解决以上问题,本文设计了两种优化方案:补充建立非缴费的第一层次养老保险为城乡居民养老保险低收入参保者提供定额补贴;降低城镇职工基本养老保险最低缴费基数。以上两种方案均增加了位于适度区间的参保者比例,对提高我国基本养老保险待遇水平的适度性具有一定促进作用。

背景:软骨组织工程主要由种子细胞、生物支架、生长因子3方面组成,如何完善软骨组织工程修复一直是科研工作者研究的重点。目的:全面了解应用软骨组织工程修复软骨损伤的研究现状。方法:计算机检索PubMed和CNKI数据库中2005/2010相关文献。以"Cartilage,tissue engineering,repair"或"关节软骨、组织工程、修复"为检索词进行检索。纳入与软骨组织工程密切相关的文献,排除重复性研究。结果与结论:共检索到167篇文献,排除无关重复的文献,保留20篇文献进行综述。研究认为种子细胞是软骨组织工程最关键的方面,包括软骨细胞、骨髓间充质干细胞、胚胎干细胞和通过基因工程得到的种子细胞。目前应用最多、应用前景最好的是骨髓间充质干细胞。生物支架经历了一个漫长的过程,趋向于复合性和功能性的方向发展。各种生长因子在组织工程中必不可少。转化生长因子、胰岛素样生长因子、骨形态发生蛋白等在软骨修复中发挥了重要的功能。

目的观察电针对血管性痴呆（VD）大鼠学习记忆功能的影响，探讨电针治疗VD的作用机制。方法将40只Sprague—Dawley大鼠分为似手术组、模型组、电针组和西药组，除假手术组行假手术外，其余各组建立VD大鼠模型。电针组术后给予电针百会、大椎穴治疗，药物组给予尼莫地半灌胃，均治疗10d。采用Morris水迷宫试验检测大鼠学习记忆能力，微电极记录海马齿状回长时程增强效应，免疫组织化学染色技术观察脑组织海马突触素（Syp）染色情况。结果与模型组比较，电针组和西药组治疗后水迷宫逃避潜伏期11月显缩短（P〈0．01），相同时间内在原平台象限跨越相应平台次数明显增多（P〈0．01），高频刺激后相对群峰电位潜伏期缩短、相对兴奋性突触后电位斜率和相对群峰电位幅值增大（P〈0．05），Syp免疫阳性细胞积分光密度值显著增大（P〈0．01）。结论电针大鼠百会、大椎穴能改善大鼠学习记忆能力，其机制可能是通过促进海马Syp的表达从而增强海马突触可塑性以及加快海马神经元突触传递过程来实现。
