Analysis on the Cohesive and Coherent Features of John Kennedy's First Inaugural Address

John Kennedy's first inaugural address is one of the widely appreciated speeches worldwide. It is famous not only for calling up the American people to well serve the country, but also for its extraordinary linguistic power to arouse the listeners' emotions, which lies to a great extent in the marvelous employment of the cohesive and coherent devices in the process of its delivery. Cohesion and coherence are two elementary and significant concepts in the theoretical system of discourse analysis. There-fore, they play an important role in the structuring, arrangement, interpretation and analysis of a discourse. In this sense, it is significant to analyze the cohesive and coherent features of John Kennedy's first inaugural address in order to obtain a penetrating comprehension of the speech in many aspects. A detailed analysis on the cohesive and coherent features of the speech has been conducted in this paper. In the aspect of cohesion in the address, the devices employed fall into two categories: structural cohesion and non-structural cohesion. Structural cohesive devices used in the discourse are mainly grammatical cohesion and lexical cohesion like repetition, ellipsis, conjunction, etc. Non-structural methods adopted in the speech are transitivity, mood and modality, thematic progression, parallel structure and so on. In the aspect of coherence, five levels of coherent methods have been employed, namely, lexical level, syntax level, semantic level, phonological level and social semiotic level. The neat intermingling of the cohesive and coherent methods function cooperatively and lead to the smooth going of the text.

Does St.John's Wort cause regression in gastrointestinal system adenocarcinomas?

St.John's Wort(SJW) is an old herb which has long been consumed widely for its anti-inflammatory,antiviral,and anti-depressive properties.Here we present a detailed clinical evaluation of three cases(two colon and one duodenal adenocarcinoma) with remarkable and intensive lymphoplasmocytic host reaction,at the basal part of tumor,intensive fibrosis,giant cells,plasma cell increase in lymph nodes and few giant cells in germinal centers in resection specimens.The observation of similar host reaction in those tumors having otherwise usual appearance was interesting.None of the cases received neoadjuvant chemoradiotherapy or additional treatment before surgery but only SJW.These cases are presented to increase the awareness about such cases.Further research is needed to reveal the possible effect of SJW,which has long been consumed for different treatment purposes,on human tumors.

A Comparative Image Study of two Love Songs——The Sun Rising by John Donne and The Love Song of J.Alfred Prufrock by T.S Eliot

The Sun Rising is one of the most famous metaphysical poems of John Donne.The Love Song of J.Alfred Prufrock is known as the first Modernist poem of T.S Eliot.This paper mainly aims to analyze the strikingly unconventional images use in the two poems,and make comments on their effect on expressing the poet emotions.

An Analysis of the Readers' Roles in the Construction of Meaning in John Donne's The Flea under Reader-Oriented Theory

Among the sundry studies in China on John Donne's The Flea,there has been none done from the perspective of Reader-Oriented Theory to probe into the readers' roles in the construction of meaning.The present article under Wolfgang Iser's theories,in a further pursuit of the expansion of the gestalt of such studies on the poem,aims at exploring the readers' active roles in complementing,completing and recreating the textual meaning,and differentiating the implied reader and the actual reader through the poem as well as attempting to fulfill the construction of the reading cognitive model through the interpretation of the conceit the flea.

Effect of St. John＇s wort extract on depressive disorder in elderly patients with unstable angina

The elderly patients with coronary heart disease （CHD） are often accompanied with depression. This study aimed to assess the effect of St. John＇s wort extract （SWE） on depressive disorder in elderly patients with unstable angina pectoris. Altogether 170 patients who met the set criteria were enrolled in this prospective study. They were randomly divided into SWE group （44 patients）, Deanxit group （44）, psychotherapy group （42）, and control group （40）. The effectiveness of SWE was evaluated by reduced percentage of Hamilton depression （HAMD） scale and reduced frequency of angina pectoris attack, which were measured before and at 12 weeks after the treatment with SWE. The reduced percentages of HAMD scale were 79.5%, 56.8% and 57.1% in the SWE, Deanxit and psychotherapy groups, respectively. Compared with the control, the three groups had significant differences in the percentages （P〈0.001）. The improvement after the treatment was more significant in the SWE group than in the Deanxit or psychotherapy group （P〈0,05）. The improvement of angina pectoris evaluated by the Canadian Cardiac Society Classification was significantly better in the treatment groups （88.7%, 65.9%, 57.1%） than in the control group, and it was marked in the SWE group （P〈0.001）. Angina pectoris attack, its frequencies, durations and electrocardiographic changes were significantly improved in the treatment groups than in the control group （F=6.05, 4.58, 5.12, P〈0.01）. They are markedly improved in the SWE group （P〈0.05）. SWE can improve depressive symptoms more significantly in elderly patients with unstable angina pectoris than Deanxit or psychotherapy, proving that SWE contributes to better treatment of angina attack as well.

基于自适应快速S变换和XGBoost的心电信号精确快速分类方法

针对心电信号(ECG)传统分类方法效率较低的问题,该文提出一种基于自适应快速S变换(AFST)和XGBoost的心电信号精确快速分类方法。该方法首先通过快速定位算法确定心电信号特征频率点,再根据特征频率点自适应调节S变换窗宽因子,增强S变换的时频分辨率的同时避免迭代计算,大大减少运行时间。其次,基于自适应快速S变换的时频矩阵提取12个特征量来表征5种心电信号的特征信息,特征向量维数低,识别能力强。最后,利用XGBoost算法对特征向量进行识别。MIT-BIH心律失常数据库和患者实测数据验证表明,该方法显著地缩短了分类时间,对5种心电信号的分类准确率分别为99.59%和97.32%,适用于实际检测系统中心律失常疾病的快速诊断。

ST酿酒酵母基因工程菌对大鼠肠道菌群的影响

为了研究ST酿酒酵母基因工程菌对大鼠肠道菌群的影响,试验将90只SPF级SD大鼠随机分为空白对照组、工程菌组及酵母菌组,分别灌服生理盐水、工程菌菌液、酿酒酵母菌菌液,持续21 d后连续3 d灌服大肠杆菌H10407菌液,分别收集灌胃7,14,21天及攻毒后的各组大鼠粪便,提取粪便细菌DNA,利用末端限制性片段长度多态性(T-RFLP)、实时荧光定量PCR检测了ST酿酒酵母基因工程菌对肠道菌群微生物可操作单元(OTU)和肠道5种重要细菌(类杆菌、梭菌、肠球菌、双歧杆菌和乳杆菌)数量的变化,并测定了肠道菌群pH值。结果表明:在灌胃期间,工程菌组及酵母菌组的OTU值和双歧杆菌、梭菌数量极显著高于空白对照组(P<0.01),其他细菌数量均不同程度升高。各组pH值均呈现下降趋势,第21天时,工程菌组及酵母菌组pH值极显著低于空白对照组(P<0.01)。攻毒产肠毒素大肠杆菌后,工程菌OTU值和类杆菌、乳杆菌、双歧杆菌数量均极显著高于其他两组(P<0.01),pH值极显著高于空白对照组(P<0.01)。与灌服前相比,工程菌组的OTU值、细菌数量及pH值均变化幅度最小。说明ST酿酒酵母基因工程菌能够改善肠道菌群结构,丰富肠道菌群多态性,降低pH值,增加有益菌群的数量。当动物机体受到产肠毒素大肠杆菌感染时,ST酿酒酵母基因工程菌能够有效降低产肠毒素大肠杆菌对肠道菌群的破坏,发挥预防保护作用,维持肠道内菌群稳定。

慢性丙型肝炎患者血清IL-33、sST2水平的检测及其临床意义

选取2014年1月~2015年10月我院收治的慢性丙型肝炎患者48例作为研究组,另选取同期于我院进行体检的健康志愿者34例作为对照组。采用ELISA法检测所有纳入对象血清中IL-33、s ST2、ALT、AST水平,并进行组间比较。结果研究组血清IL-33、s ST2、ALT、AST水平均明显高于对照组,差异均具有统计学意义（P〈0.05）;研究组患者血清IL-33、s ST2水平与ALT、AST水平呈明显正相关（rIL-33,ALT=0.483,rIL-33,AST=0.501,rs ST2,ALT=0.397,rs ST2,ALT=0.424,P〈0.05）。慢性丙型肝炎患者血清IL-33、s ST2水平异常升高,在一定程度上可反映肝脏的炎症程度,检测其血清水平有助于了解患者肝脏损伤情况,为临床诊治提供一定依据。
