关于抽象代数中两个结论的证明——关于自由Abel群及高斯整数环的注记

对抽象代数中如下两个结论：（1）存在自由Abel群;（2）高斯整数环是欧氏环。在文献[1]、[2]、[3]中都给出了传统理论意义上的证明。此文分别给出一种不同于已有文献的证明方法。     

跨语言信息检索的偏最小二乘方法研究

基于辞典的模式和机器系统翻译的技术一度成为人们进行跨语言信息检索的热点研究技术.基于辞典的模式就是采用机读辞典来做翻译,这里主要的问题是词汇的歧义性,另一个问题是辞典本身的覆盖度不够,翻译往往不够确切.为解决上述问题,本文提出了一种基于偏最小二乘理论的中间语义的跨语言信息检索方法.     

论“杯具”的音译——从文化的本体论特征谈起

"杯具",这一中国网络当红语录,它与"悲剧"一词同音且同义,但它却更生动形象的体现着当下中国人的心理.随着它的广泛流行,已被中国人渐渐的接受,因此,作为一种独特的文化而沉淀下来.文章结合文化的本体论特性及其传播,来研究"杯具"的翻译,并借此进一步探讨文化专有名词的音译与传播.     

公共艺术教育在普通高校素质教育中的作用及实现途径

公共艺术教育是高等院校素质教育的一项重要内容,在提高大学生综合素质,促进大学生身心和谐健康发展,培养创新思维等方面具有重要作用。针对目前公共艺术教育实施过程中所存在的问题,各高校应从课程设置、管理机构、师资队伍、教学设施、教学环境、教育评估等方面,加强公共艺术教育的建设,保障公共艺术教育的顺利开展和健康运行,充分发挥公共艺术教育在促进大学生全面发展方面的重要作用。     

中学语文阅读教学的三个层次

在中学语文教学中必须实行有层次的阅读教学。阅读教学要引导学生重视语言的分析和品味,把握分析比较的方法,在尊重文本、尊重历史的基础上,积极主动思考,大胆创新。     

新建本科院校新生心理健康调查与分析

通过对某新建本科院校新生的心理普查,发现:大学新生在情绪性格、人际关系等方面存在着一定的困惑;新生的心理健康状况男女基本在同一水平上;农林类专业新生的心理测量结果不容乐观;家庭年收入水平对于UPI的总分分布率有显著影响。因此,加强新生心理适应期的健康教育,帮助新生设计合理的生涯规划,在新生中开展有效的贫困生教育工作显得尤为重要。     

Successful recanalization of chronic total occlusion of the superior mesenteric artery by transradial approach

It is a challenge to confirm chronic mesenteric ischemia (CMI) as a cause of gastrointestinal (Gl) symptoms such as postprandial epigastric bloating,anorexia,and debilitating weight loss.Endovascular intervention for CMI has been gaining popularity because of the high morbidity associated with surgical revascularization.However,in EVI for superior mesenteric artery (SMA) occlusion,the transfemoral approach is limited by difficulty in coaxial alignment of the guiding catheter,which leads to insufficient back-up support.Herein,we report on a 58-year-old male patient with chronic total occlusion of the SMA,which was successfully revascularized by endovascular intervention via the left radial artery.Transradial endovascutar therapy may be another treatment option for the treatment of CMI.     

Congenital atresia of the left main coronary artery in an infant

Congenital atresia of the left main coronary artery is a rare occurrence, and surgical revascularizationbypass graft is required. We here report a rare case of congenital coronary anomaly in an infant. A 10-month-old male infant was admitted to the hospital with heart failure symptoms. Echocardiographic examinations revealed mitral valve regurgitation and ischemic changes of the anterolateral papillary muscle and chordae. Coronary angiography showed atresia of the left main coronary artery with a severe hypoplastic left anterior descending artery and a circumflex coronary artery. Unfortunately, sudden cardiac arrest occurred after catheterization and the infant did not recover despite of immediate cardiopulmonary resuscitation. Further studies are needed to find a newer diagnostic method to detect coronary anomaly in an infant, and coronary angiography, if necessary, has to be performed very carefully.     

Clodronate-containing liposomes attenuate lung injury in rats with severe acute pancreatitis

Objectives:Severe acute pancreatitis(SAP) can lead to acute lung injury(ALI) .The purpose of this paper is to investigate the protective effect of clodronate-containing liposomes on ALI in rats with SAP.Methods:The thin film method was used to prepare liposomes.Sprague-Dawley rats were randomly divided into three groups.After the SAP model was established by injecting 5%(w/v) sodium taurocholate(2 ml/kg body weight) into the subcapsular space of the pancreata,normal saline was administered to the control(C) group,phosphate buffer solution(PBS) -containing liposome to the Pgroup,and clodronate-containing liposome to the Tgroup through tail veins.Blood samples were obtained from the superior mesenteric vein at 2 and 6 h to measure the levels of amylase,interleukin-6(IL-6) ,and tumor necrosis factor-α(TNF-α) .Morphological changes in the pancreata and lung were observed using hematoxylin and eosin(HE) staining,while cell apoptosis was detected using terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling(TUNEL) .In addition,the macrophage marker cluster of differentiation 68(CD68) in lung tissue was detected with immunohistochemistry.Results:Blood levels of amylase,IL-6,and TNF-αwere significantly increased in the Pgroup compared to those in the Tgroup(P0.05) .In the Tgroup,large numbers of TUNEL-positive cells were observed,but no or few in the C and Pgroups.Gross inspection and HE staining of pancreata and lung showed dramatic tissue damage,including inflammation and necrosis in the Pgroup.Less remarkable changes were noted in the Tgroup,and the C group exhibited normal histology.The histological scores according to Kaiser's criteria were consistent with HE findings.The number of CD68-positive macrophages decreased in the Tgroup.Conclusions:Clodronate-containing liposomes have a protective effect against ALI in rats with SAP.Blockade of macrophages may represent a novel therapeutic strategy in SAP.
