The uses of a patient-based dietetic data-collection systern

The F.I.P. (Financial Information Project) dietetic package allows the collection of basic patient data, which then can be processed to give valuable clinical and management information for use by all dietitians in a dietetic department. The advent of the Korner Reports (DHSS, 1984a) and their implementation highlighted the need to computerize certain aspects of data collection in dietetic departments. Within the West Midlands Regional Health Authority a group of dietitians worked with the Regional Management Services Department to adapt a community nursing system, F.I.P., for use by dietitians. The system was piloted for all paramedical services in 1987 with one health district (North Warwickshire) piloting the dietetic package. It is now used by a range of dietetic and paramedical departments. This paper outlines the system and its uses.     

心血管病流行病学研究必需的基础和专业知识

本文从心血管病流行病学研究工作的实际体会中提出:当前要提高科研工作水平的关键是提高研究防治队伍的科学素质.其中包括:应具备流行病学和生物统计学的基本知识,必要的心血管病临床知识和实践经验,关心常见心血管病的基础研究进展,和学习有关专业的知识,如营养学、行为医学、遗传学等.解决的办法除集中培训,个人努力学习外,更需组织有不同专业基础而有志于心血管病流行病学研究工作的人员密切合作,相互学习,取长补短,以达到共同提高.     

明清时期新安药店及其医药学作用

新安药店始于宋，成于明，至清末一度达到鼎盛。较有代表的宋有“陆氏保和堂”，明有“徐保元堂”、“正田药店”、“胞与堂”等，清有“胡庆余堂”、“胡咸春”、“种德堂”等。这些药店明多为医家兼营，清多为徽商经营。新安药店作为集医疗、生产、经营一体的传统手工业，至今不少成为著名药厂，如“武汉健民制药厂”、“胡庆余堂”等。其在生产、经营、管理上积累了许多经验，同时在方剂学以及药物炮炙、贮藏、采集、加工、成方制作等方面皆有不少成就。     

Family system test (FAST): Are parents' and children's family constructs either different or similar,or both?

Perceptions of family cohesion and hierarchy structures were assessed by theFamily System Test (FAST), a clinically-derived figure placement technique. Parents (N=140) and their preadolescent offspring (N=70) completed typical and conflict representations in individual as well as group settings. Typical representations were characterized by balanced family structures (i.e. cohesive and moderately hierarchical) and those displaying conflict situations showed predominantly unbalanced patterns. FAST portrayals were related to respondent (mother vs. father vs. child). Fathers represented typical family relations as balanced more often than mothers. Regarding conflict representations, children were more likely than fathers to portray the family as unbalanced. However, analyses of representations of the same family (i.e. intra-family comparisons) indicated that all respondents differed in their perceptions and, that fathers' typical portrayals showed most often the same structure as those done by the family members as a group.     

化工废水中N-亚硝基二正丙胺的吹扫捕集-GC-MS测定法

目的建立简单快速提取并测定N-亚硝基二正丙胺(NDPA)的方法。方法采用Trap3捕集管,利用标准吹扫捕集程序(吹扫气体流速40ml/min,吹扫时间11min,解吸温度225℃,解吸时间4min,烘烤温度230℃,烘烤时间10min),有效富集了化工废水中μg/L级的NDPA,建立了吹扫捕集(P&T)气相色谱质谱联用(GC-MS)化学源(CI)选择离子模式(uSIS)快速、准确分析废水中NDPA的分析方法。结果方法的相对标准偏差为7.5%;废水的加标回收率在62.60%～96.31%;在5～30μg/L范围内线性良好,线性回归系数为0.978;方法的最低检出限为3μg/L。结论采用P&T-GC-MS/CI/uSIS法可用于化工废水中半挥发性有机物NDPA的测定。

The epidemiology of urinary dysfunction in Chinese women

The epidemiology of urinary dysfunction in a Chinese population living in Hong Kong was investigated. Fifteen hundred ethnic Chinese women answered a telephone questionnaire including symptoms of urinary dysfunction, anthropometric measurements, obstetric history and place of birth. The relative predictive value of these factors was analyzed using logistic regression. The prevalence of urinary dysfunction was 13%. Ten percent reported stress incontinence, and 4% had urgency or urge incontinence. The strongest predictor was place of birth, with women born in mainland China having the highest prevalence of pure stress incontinence (OR 1.33, CI 1.1–1.6). For the symptoms of detrusor instability age was the strongest predictor, with women over 50 years being at greater risk (OR 2.8, CI 1.6–5.0). Contrary to earlier beliefs, urinary dysfunction in Chinese women is as common as in Caucasian women. Place of birth is the strongest predictor for pure stress incontinence, with women born in mainland China being at greater risk. This suggests that environmental factors in early life have a differential effect on the development of urinary incontinence. EDITORIAL COMMENT: Taiwan Chinese women have a comparable prevalence of urinary dysfunction with Hong Kong Chinese women. A survey representing a multistage sample of 82 678 women aged 18 years or older was conducted in the Taipei area from January to June 1993. A total of 818 cases were interviewed by trained students. One hundred and eighty-nine (23.1%) of the respondents reported having had some degree of incontinence in the preceding 12 months, 28 (3.4%) reporting regular incontinence. Most presented with stress urinary incontinence, whereas urge incontinence and mixed incontinence were more commonly seen in the elderly group (aged 60 years or older). The risk factors for urinary incontinence included age, number of vaginal deliveries (>3), number of abortions (>2) and maternal history of incontinence. Voiding symptoms (irritative or obstructive) and constipation were significantly more prevalent among respondents with incontinence than those without (P<0.001). This evidence also indicates that the long-held belief that Chinese women have a much lower prevalence of urinary dysfunction than western women has all but ended.
