Assessing the Effectiveness of a Cervical Cancer Screening Program in a Hospital-based Study

This study compared HPV testing and liquid-based cytology （LCT） as performance indicators for cervical cancer screening in a hospital-based study. A total of 61,193 outpatients were screened initially by LCT. Samples with screening results showing atypical squamous cells of undetermined significance （ASC-US） or worse were referred for colposcopy, and some samples were tested for high-risk HPV types with the Hybrid Capture II system （HC II）. Data on LCT （n=61,193） and HC II （n=1056） results were analysed. Overall test positivity for LCT was 2.53% using an ASC-US threshold, 3.11% using a low-grade squamous intraepithelial lesion （LSIL） threshold, and 0.67% using a high-grade squamous intraepithelial lesion （HSIL） threshold. A total of 1839 women （84% of the 3893 patients with abnormal cytology） underwent colposcopy-directed biopsy. HPV was positive in 80.3% of women with cervical intraepithelial neoplasia 1 （CIN1）, 88.3% of those with CIN2, 79.2% of women with CIN3 and 50% （2 of 4） of women with invasive cancer. There was a significant increase in the detection of CIN2 or worse with adjunct HPV testing of women with ASC-US and LSIL However, there were detection of CIN2＋ cases no differences in the with adjunct HPV testing of women with HSlI.. The results indicate that HPV testing for HSlL triage should not be recommended in cervical cancer screening.

A Case Study of Intercultural Interventions for Chinese University Students During Study Abroad Program in the University of Minnesota

In 21st Century, Chinese and American universities are experiencing great development in the number of students studying abroad. This research adopts the method of natural investigation, selecting Chinese student samples during study abroad program in the University of Minnesota to complete the designed questionnaires to examine the intercultural interventions taken before, during and after this type of study abroad in Chinese universities. Also, after students complete the questionnaires, email communication is made to analyze the reasons for their answers to the questionnaires. The questionnaire results and email communication show that there is a great gap in the practice of intercultural interventions in study abroad programs between Chinese universities and students expectations. It is time for Chinese universities to design appropriate intercultural interventions in order to maximize Chinese university students＇ intercultural development during study abroad. These intercultural interventions should be run consistently to cover the phrases of pre-departure, during and after the study abroad program. Also, more dynamic and interactive intercultural interventions rather than knowledge-based intercultural instructions or guidance should be the focus for intercultural interventions.

A Study on Standards System ofChinese Environmental Labeling Program

Implementing Outlines for the Chinese Environmental Labeling Program Byawarding certificates and labels to related manufacturers in accordance with certain environmentallabeling standards, environmental labeling, also called ''Green Label''or ''Eco-label'', certifies viagovernmental departments or public and private organizations that the whole process of producing,using, recalling and disposing of manufacturers'' products is in compliance with certainenvironmental requirements. Many countries are establishing and promoting environmental labelingplans. Environmental labeling, as an important promotion means for prevention and control ofpollution in a market-oriented manner, is being extended and developed constantly across the world.

Effect of dexamethasone on intelligence and hearing in preterm infants: a meta-analysis

OBJECTIVE： A meta-analysis of published randomized controlled trials investigating the long- term effect of dexamethasone on the nervous system of preterm infants. DATA SOURCES： Online literature retrieval was conducted using The Cochrane Library （from January 1993 to June 2013）, EMBASE （from January 1980 to June 2013）, MEDLINE （from Janu- ary 1963 to June 2013）, OVID （from January 1993 to June 2013）, Springer （from January 1994 to June 2013） and Chinese Academic Journal Full-text Database （from January 1994 to June 2013）. Key words were preterm infants and dexamethasone in English and Chinese. STUDY SELECTION： Selected studies were randomized controlled trials assessing the effect of intravenous dexamethasone in preterm infants. The quality of the included papers was evaluated and those without the development of the nervous system and animal experiments were exclud- ed. Quality assessment was performed through bias risk evaluation in accordance with Cochrane Handbook 5.1.0 software in the Cochrane Collaboration. The homogeneous studies were analyzed and compared using Revman 5.2.6 software, and then effect model was selected and analyzed. Those papers failed to be included in the meta-analysis were subjected to descriptive analysis. MAIN OUTCOME MEASURES： Nervous system injury in preterm infants. RESULTS： Ten randomized controlled trials were screened, involving 1,038 subjects. Among them 512 cases received dexamethasone treatment while 526 cases served as placebo control group and blank control group. Meta-analysis results showed that the incidence of cerebral palsy, visual im- pairment and hearing loss in preterm infants after dexamethasone treatment within 7 days after birth was similar to that in the control group （RR = 1.47, 95%CI： 0.97-2.21; RR = 1.46, 95%CI： 0.97-2.20; RR = 0.80, 95%CI： 0.54-1.18; P 〉 0.05）, but intelligence quotient was significantly de- creased compared with the control group （MD = -3.55, 95%CI： -6.59 to -0.51; P = 0.02）. Prete rm infants treated with dexamethasone 7 days after birth demonstrated an incidence of cerebral palsy and visual impairment, and changes in intelligence quotient similar to those in the control group （RR = 1.26, 95%CI： 0.89-1.79; RR = 1.37, 95%CI： 0.73-2.59; RR = 0.53, 95%CI： 0.32-0.89; RR = 1.66, 95%CI： -4.7 to 8.01; P 〉 0.05）. However, the incidence of hearing loss was significantly increased compared with that in the control group （RR = 0.53, 95%CI： 0.32-0.89; P = 0.02）. CONCLUSION： Dexamethasone may affect the intelligence of preterm infants in the early stages after birth, but may lead to hearing impairment at later stages after birth. More reliable conclusions should be made through large-size, multi-center, well-designed randomized controlled trials.

Biosystems Engineering Curricula in Europe

This paper describes the history of the harmonisation of agricultural/biosystems engineering degree study programs in Europe from 1989, when the need for this process was widely felt, until now, when this need was partly satisfied through the implementation of the projects of two EU funded thematic networks, i.e., USAEE-TN and ERABEE-TN. The objective of this paper is to contribute to promote, in each EU country and elsewhere, the process of harmonisation of agricultural/biosystems engineering degree study programs, and student and graduate mobility within the EU, as well as between the EU and the USA. At present, in Europe, this harmonisation process is aided by the key results of the projects of USAEE-TN, ERABEE-TN and POMSEBES. USAEE developed some core curricula, to be used as benchmarks for European agricultural/biosystems engineering degree study programs, and a web-based database of these study programs. ERABEE promoted the transition from agricultural engineering to biosystems engineering and established the recognition procedures of new European study programs in biosystems engineering. The EU-US POMSEBES consortium built up a platform for exchange of experiences and ideas between the USA and the EU, aimed at： enhancing the quality and linkage of research and education; establishing appropriate policy oriented measures; promoting compatible degree study programs in biosystems engineering, within the EU as well as between the EU and the USA.

AN OVERALL STUDY OF CONVERGENCE CONDITIONS FOR ALGORITHMS IN NONLINEAR PROGRAMMING

Since the point-to-set maps were introduced by Zangwill in the study of conceptual algorithms, various sufficient conditions for the algorithms to be of global convergence have been established.In this paper, the relations among all these conditions are illustrated by a unified approach;still more, unlike the sufficient conditions previously given in the literature,a new necessary condition is put forward at the end of the paper, so that it implies more applications.
