大学英语的词汇教学

词汇是语言的三大要素之一,是构筑语言大厦的基石,是语言表达的主要承担者。正如语言学家D．A．Wilkins(1972)所说,“without grammer little can be conveyed,without vocabulary nothing can be conveyed．”(没有语法,人们可以表达的事物寥寥无几;而没有词汇,则无法表达任何事物)。能否突破词汇关,是英语学习成败的关键。没有词汇,     

Syntax score predicts clinical outcome in patients with three-vessel coronary artery disease undergoing percutaneous coronary intervention

Background  The Syntax score was recently developed as a comprehensive, angiographic tool grading the complexity of coronary artery disease (CAD). It aims to assist in patient selection and risk stratification of patients with extensive CAD undergoing revascularization. However, the prognostic value of the Syntax score in patients undergoing percutaneous coronary intervention (PCI) has not been validated. The aim of this study was to evaluate its role in predicting long-term incidences of major adverse cardiac and cerebrovascular events (MACCE) in patients undergoing PCI for 3-vessel disease.

Methods  Two hundred and three consecutive patients with de novo 3-vessel CAD undergoing PCI with sirolimus-eluting stents were studied. Their angiograms were scored according to the Syntax score. The patients were divided into tertiles according to the Syntax score: lowest Syntax score tertile (Syntax score ≤22), intermediate Syntax score tertile (Syntax score of 23 to 32), and the highest Syntax score tertile (Syntax score ≥33). During the 1-year follow-up, the MACCE-free survival curves were estimated by the Kaplan-Meier method. Univariate and multivariate Cox proportional hazard regression analyses were performed to evaluate the relation between the Syntax score and the incidence of MACCE. Performance of the Syntax score was studied with respect to predicting the rate of MACCE by receiver operator characteristic (ROC) curves with an area under the curve.

Results  The overall Syntax score ranged from 6 to 66 with mean ± standard deviation of 27.9±12.6 and a median of 26. At 1 year, the Syntax score significantly predicted the risk of MACCE (HR 1.07/U increase, 95% CI 1.04 to 1.11, P <0.001). The rate of MACCE was significantly increased among patients in the highest Syntax score tertile (17.9%) as compared with those with the lowest Syntax score tertile (1.4%, P <0.001) or intermediate Syntax score tertile (6.2%, P=0.041). After the adjustment for all potential confounders, the Syntax score remained a significant predictor of the rate of MACCE (adjusted HR 1.12/U increase, 95% CI 1.05 to 1.20, P <0.001). The Syntax score accurately predicted MACCE with an area under the receiver operator curve of 0.77 (95% CI 0.65 to 0.90, P <0.001). A Syntax score of 29.5 was identified as the optimal cutoff to predict MACCE with a sensitivity of 82.4% and specificity of 65.6%.

Conclusion  The Syntax score predicts the risk of MACCE in patients with 3-vessel disease undergoing PCI.

基于知识元标引的中医古籍研究回顾与反思

回顾国内以往知识元研究,结合当前中医古籍知识元研究工作,探讨中医古籍研究的部分现存问题.中医古籍知识元研究工作重点在于知识元标引平台的研发以及中医基础理论的数据化处理.知识元的概念是文本中的词或短语;知识元的文本可以借助文言语法与知识图谱三元组概念进行数据提取;建立语义关系,即语义三元组的描述,可分为表达不同描述对象(实体)之间语言逻辑的"实体—关系—实体"形式,与表达描述性语句的"实体—属性—属性值"形式.语义三元组间的逻辑关系及其描述,要求对古籍文本进行词、句法、语义、语用等全方位的考察.逻辑语法的研究或可为知识元研究开拓新路径.     

新生胶囊的质量标准研究

 目的 建立新生胶囊的质量控制方法。方法 采用TLC对新生胶囊中的黄芪、赤芍、延胡索、洋金花和甘草进行了定性,并用薄层扫描法对黄茂中的黄芪甲苷进行了含量测定。结果 黄芪甲苷在2～7μg·μl〈sup〉-1〈/sup〉范围内呈线性关系,回收率为96.3%,RSD为2.3%。结论该法简单快速,结果可命,可用于控制新生胶囊的质量。
