包头市居民吸烟状况调查

目的：为了搞清包头市居民的吸烟情况。方法：按照流行病学调查表的要求，由卫生医师逐户、逐人询问调查对象吸烟情况、吸烟量和被动吸烟状况，以及与吸烟有关的年龄、性别和住址，将核实后的调查资料按统一设计程序，采用SAS统计软件包在计算机上进行统计处理。调查结果表明：市区居民吸烟率为38．34％，农牧区居民的吸烟率为50．68％，男性高于女性；吸烟量多在10支以上、25支以下，以农牧区每日吸烟量超过10支者所占比例最大(63．16％)，且男性居民25岁组以后达到高峰一直维持到60岁组；女性居民的被动吸烟者和被动吸烟量较男性多。结论：居民的吸烟状况在性别、年龄、城乡和受教育情况等方面有不同的分布。     

A strategic design approach to develop sustainable product service systems: examples taken from the ‘environmentally friendly innovation’ Italian prize

The product service systems’ (PSS) sustainability potential is described in the framework of the new types of stakeholder relationships and/or partnerships, producing new convergence of economic interests, and a potential concomitant systemic resources optimization.In this perspective, it is argued that the design competencies should move towards those of the ‘strategic design’, thus introducing the concept of ‘strategic design for sustainability’: the design of an innovation strategy, shifting the business focus from designing (and selling) physical products only, to designing (and selling) a system of products and services which are jointly capable of fulfilling specific client demands, while re-orienting current unsustainable trends in production and consumption practices.Some examples of PSS are presented and discussed using the PSS categories ‘services providing added value to the product life cycle’, ‘services providing final results to customers’, and ‘services providing enabling platforms for customers’. The cases derive from an analysis of the ‘environmental friendly innovation’ yearly endowed prize submissions. The Politecnico di Milano University together with the Bocconi University and Legambiente (an environmental NGO) promotes the initiative in Italy.     

低空分层降水和云水同步采集系统的开发和应用

笔者自行开发并研制了低空（ ＜ １ ｋｍ） 分层降水和云水采集系统，该系统成功地应用于福建省厦门市和贵州省贵阳市酸性降水来源和成因的研究中，取得了显著的成果，为探讨酸性降水来源和成因提供了有效的技术手段和支持。该系统可以在一定程度上代替航空测量，目前国内外的类似研究中没有使用该系统进行样品采集的先例，因此该系统的开发填补了国内外相关研究领域的空白     

Factors associated with multiple-pass procedures during chorionic villus sampling: A video analysis

Multiple placental passes during chorionic villus sampling (CVS) increase the risk of fetal loss; however, specific factors that predispose to repeat aspiration have not been delineated. To identify anatomic and technical variables associated with multiple-pass procedures, a detailed review of 205 videotaped CVS procedures (single pass = 163; multiple pass = 42) was performed, blinded to pregnancy outcome. The route of sampling did not influence the need for multiple aspiration attempts (transabdominal—30/ 135; transcervical—12/70), nor was placental location alone discriminatory. However, the combination of a posterior placenta and uterine retroversion was observed more frequently in the multiple-pass cohort (8/42 vs. 9/163; p<0.05). In transabdominal cases, suboptimal needle placement (e.g., perpendicular to the placental long axis) was more common in the initial aspiration of a multiple-pass procedure (21/30 vs. 38/105;p<0.01), while limited penetration of the catheter tip (e.g., just inside the placental edge) characterized a majority of multiple-pass cases in the transcervical subset (7/12 vs. 3/58; p<0.0001). A case-control cohort was constructed to evaluate the impact of these technical variables on sampling efficacy, independent of the influence of uterine position and placental site. In that analysis, suboptimal location and/or orientation of the sampling device remained characteristic of multiple-pass cases. We conclude that further reduction in the frequency of multiple-pass procedures might be achieved by consistent placement of the device tip in the central placental mass. Unlike amniocentesis, where any point of amnion entry will suffice, this technical nuance should be emphasized with CVS to maximize the single-pass success rate.
