To the Editor:Frailty status represents one of the core determinants for the individualization of glycated hemoglobin(HbA1c)targets in the elderly ***,the most validated tools to quantify frailty,which are complex and involve multiple dimensions of assessment,are rarely used in the clinical practice of diabetes ***,a simple and practical metric for the evaluation of frailty is *** strength is an easily measurable,objective,and reproducible metric for assessing frailty status.[1]It is correlated with overall muscle strength and has been reported to be signicantly related to important health outcomes both in the general population[2,3]and in patients with diabetes.[4]Therefore,grip strength could be a useful marker for patient strati-cation in diabetes *** this context,this study aimed to examine the associations between HbA1c and all-cause mortality across categories of grip strength,as a measure of frailty status,in older adults with type 2 diabetes in the UK *** researches had applied to access the UK Biobank database with the application approval number of 82812.

元认知是以监测和控制为核心的动态调节活动。本研究以9岁儿童、年轻人和老年人为研究对象,分别采用选点任务和词对学习任务,在知觉元认知和高阶元认知层次考察元认知监测和控制及其关系随年龄变化的特点。结果显示:(1)儿童的知觉元认知和高阶元认知监控能力大都低于年轻人;(2)老年人的知觉元认知能力与年轻人相似,但高阶元认知能力则低于年轻人;(3)老年人和年轻人一样能够在记忆监测中利用控制线索,而9岁儿童尚未表现出这种能力。本研究从发展的角度,支持了知觉元认知与高阶元认知能力具有领域特殊性的理论假设,并对监测和控制的关系发展进行了讨论。

武术散打起源于中国,近代散打在我国已发展了30多年,经过一代又一代散打人的不懈努力,我国的散打总体水平已处于世界前列。我国散打中、小级别在国际上有一定的优势,技术发展也日益透彻,成绩也较为突出,多次获得世锦赛金牌,而大级别散打运动员并没有取得国际领先地位,在国内的关注度也较低,本文通过分析大级别运动员比赛中拳、腿、摔等动作中的频率及有效得分率,得到最实用,成功率最高的技术动作,能使今后的散打大级别运动员在比赛与训练中得到事半功倍的效果,为日后的训练目标、有效得分率提供间接的参考。本文采用文献资料、录像观察、数理统计等方法,对第13届全国运动会武术散打决赛的男子大级别运动员(共8人,6场)进行技术运用统计分析,研究表明:单击拳法、单击腿法、拳腿组合是大级别运动员比赛中主要的进攻技术与得分手段,其中,拳腿组合与近身摔法的得分率较高,拳法的成功率较低,建议男子大级别运动员在训练中以拳腿组合、近身摔法为主,同时加强组合拳法的运用次数及单击拳法的杀伤力。

荆楚文化是中华民族文化的重要组成部分,继承了很多商朝、周朝的文明,源远流长,薪火相传,历久弥新,体现出区别于其他地域的特点,在推动荆楚地区经济发展方面发挥了重要作用。茶叶是中国传统文明的象征,考古发现,6000年前生活在余姚田螺山的先民已经开始种植茶树。作为传统饮品之一的茶叶的包装设计在产品推广和增强茶叶品牌的市场竞争力方面起着重要作用。文章主要概括茶文化和荆楚文化的背景及研究意义,介绍茶叶包装的发展状况以及不足之处,以荆楚传统植物纹样为切入点,整理归纳荆楚植物纹样的背景与分类,探讨它们在茶叶包装设计中的运用。同时,文章还系统调查我国茶叶包装发展现状和不足之处,分析荆楚传统纹样,提取莲花纹、梅花纹、牡丹纹这三种不同的植物纹样,并在将荆楚传统植物纹样应用到茶叶包装设计之前进行信息收集与调研,以更好地将植物纹样与茶叶包装有机结合。在设计实践中,分别从以下几个方面应用荆楚植物纹样:一是纹样的取形延意,二是线性线条的灵活运用,三是其他衍生产品的应用。不断改进并深入研究,不仅可以进一步突出茶叶包装的设计特色,还有利于人们深入了解中国传统文化,感受中国传统纹样的魅力。
