Objectives This study was design to develop a semi-quantitative Chinese Food Frequency Questionnaire （FFQ） and to conduct a validation study for the questionnaire. Methods Based on the survey experience in recent years, a new Chinese food frequency questionnaire （FFQ） with 149 items in 17 food categories was developed. A validation study on this new FFQ was conducted in Jiangsu and Beijing of China between 1999 and 2001. The period of study covered 1 year and the FFQ was validated by comparing with data obtained by a six repeated 24-hour recalls for 3 consecutive days, or a totally 18-day 24- hour recall throughout the year. A total of 271 healthy adult subjects were enrolled in the study. Food and nutrient intakes measured by the 18-day dietary recalls and food frequency questionnaires （FFQs） were computed in the National Institute for Nutrition and Food Safety, China CDC using the existing nutrition database. The average daily intake of foods and nutrients over the 18-day recall was used to compare with FFQ1 and FFQ2, which was conducted at the beginning and the end of the year, respectively. All statistical analyses were carried out using SAS software version 6.12.

膳食脂肪和心脏代谢健康:证据、争议和指导共识

中国化学会第28届学术年会

作者： John D.Holliday Peter willett Information School University of Sheffield

Any similarity measure that is to be used for similarity-based virtual screening （SBVS） has three principal components:the structure representation,the weighting scheme,and the similarity coefficient [1].The many previous studies of SBVS that have been carried out have demonstrated that effective screening can be achieved using binary fingerprints and the Tanimoto *** studies [2,3] discussed the interactions between representation,weighting scheme and similarity coefficient when a chemical similarity measure is *** their study,it was shown that the Tanimoto coefficient is effective for binary （unweighted） similarity searching,but it has been suggested that other coefficients may be superior to the Tanimoto coefficient when applied to non-binary representations [4].In this study,we consider of different similarity coefficients when used with weighted fingerprints and different datasets,*** class,heterogeneous class or high diversity datasets,to evaluate the effectiveness the similarity measure for SBVS.
