This study was to evaluate the efficacy and toxicity of LCAHFR combined with FP chemotherapy in treating esophageal cancer. Methods: Reports of randomized clinical trials on LCAHFR combined with FP chemotherapy for esophageal cancer published between January 1999 and January 2009 were researched through Wanfang, CNKI, and PubMed databases. RevMan4.2 software was used for Meta-analysis. Results: Twenty-one reports, including 2030 patients, were included in the meta-analysis. Of the 2030 patients, 1006 underwent LCAHFR (LCAHFR group), and 1024 underwent LCAHFR combined with FP chemotherapy (combination group). Compared with those of the LCAHFR group, the 1-, 2-, 3-, 5-years survival rates and 1-, 2-, 3-year local control rates of the combination group were significant increased, and the acute toxicity was also increased, but chronic toxicity showed no significant difference. C onclusions: LCAHFR combined with FP chemotherapy can improve the survival rate and the local control rate of the patients with esophageal cancer. The increased acute toxicity need to be concerned, whereas the chronic toxicity needs a long-term observation.展开更多

Taking help from available questionnaires and also incorporating views from the teachers of the related subjects, the relevant Likert type items were selected. The drafted version of the questionnaire was finalized taking into account feedback from the subject experts. The focus was on simple language to ensure clarity to the students to facilitate accuracy of the collected data. The developed questionnaire consists of five domains involving fifteen Likert type items including a global item. For assessment of its reliability and validity, data were collected among two groups of undergraduate students studying two courses namely Accounts (n = 190) and Law (n = 90). For assessing questionnaire, Karl Pearson Correlation Coefficient, Cronbach’s Alpha coefficient and four factor solutions under factor analysis were used. The analytical results were quite consistent across the data sets (that are, accounts, law and pooled together) that exhibit good psychometric properties. It may thus be concluded that the questionnaire is valid, reliable and may measure what it is intended to measure.展开更多

Thus, tur...Recent years, problems of the current college English courses, such as test-oriented teaching, wasteful duplication of language skills teaching, etc., have been criticized by educators and students in China. Thus, turning skill-based English courses into content-based ESP (English for Special Purposes) courses has become a tendency at colleges and universities in China. The purpose of this paper is to analyze factors influencing the design of such courses through the means of questionnaire, individual interviews, data survey (e.g., educational plans) etc.. We found the following factors throw light on the questions relating to curriculum design of ESP courses: (1) the learners' learning needs; (2) the social needs (esp. labor market needs); and (3) the academic needs from the university. The analysis serves to reveal the gap between the school system and actual social and students needs. With these factors in mind, designers of such courses can adjust goals, contents, approaches, and assessments in the practical teaching. And thus these factors would enable content-based ESP courses to reflect learners' needs better and lead to more effective langrage learning in college English teaching field.展开更多

HCTCRB has been designed and used as a basis for empirical approaches and in empirical practices. These methods are not all-encompassing enough to adequately explain the behaviour of HCTCRB in the field. Recent developments in mechanistic approaches have proven more reliable in the design and analysis of pavement, making it possible to more effectively document the characteristics of HCTCRB. The aim of this study was to carry out laboratory testing to assess the mechanical characteristics of HCTCRB. Conventional triaxial tests and repeated load triaxial tests (RLT tests) were performed. Factors affecting the performance of HCTCRB, namely hydration periods and the amount of added water were also investigated. It was found that the shear strength parameters of HCTCRB were 177 kPa for cohesion (c) and 42~ for the internal friction angle (~). The hydration period, and the water added in this investigation affected the performance of HCTCRB. However, the related trends associated with such factors could not be assessed. All HCTCRB samples showed stress-dependency behaviour. Based on the stress stages of this experiment, the resilient modulus values of HCTCRB ranged from 300 MPa to 1100 MPa. CIRCLY, a computer program based on the multi-layer elastic theory was used in the mechanistic approach to pavement design and analysis, to determine the performance of a typical pavement model using HCTCRB as a base course layer. The mechanistic pavement design parameters for HCTCRB as a base course material were then introduced. The analysis suggests that the suitable depth for HCTCRB as a base layer for WA roads is at least 185 mm for the design equivalent standard axle (ESA) of 10 million.展开更多
