基于伪F统计量的模糊聚类方法在医疗质量综合评价中的应用

目的探讨一种新的基于伪F统计量的最佳聚类分析方法,该方法不需要预先选择类的数目作为先验值.并有效地应用于医疗质量的综合评价.方法首先,应用FCM模糊聚类法(Fuzzy Clustering Method)进行聚类,然后应用PFS(Pseudo F-statistics)统计量作为一个判别函数来确定最佳类数目.结果将该方法应用于某院2002年度各科室医疗质量综合评价,得到了一种合理的综合评价结果.结论该方法基于没有聚类数据的任何先验知识和组成成分信息的前提下,考虑如何确定数据的分类结构.根据应用的情况,发现该方法是医疗质量综合评价的有力工具.

Natural Course of Silicosis in Dust-exposed Workers

Silica-containing dust and silicosis have beenattracting more and more attention with numerousresearches worldwide[1 ,2], especially in China .However ,few studies have been conducted con-cerning the criteria of the period and content ofmedical examination of health surveillance for dust-exposed workers[3]. Since 1986 an epidemiologicalstudy onthe relation of silica dust exposure ,silico-sis and lung cancer was jointly made by TongjiMedical College , US National Cancer Institute andthe US …     

我国疾病预防控制中心人力配置标准研究

目的提出我国疾病预防控制中心人力配置标准。方法以履行公共职能为原则,以工作效率提高为前提,通过对现有人力配置的调整获得人力配置标准。结果按未来3～5年内公共职能落实程度计,省级疾病预防控制中心人力配置标准为336人,市级疾病预防控制中心为102人,县级疾病预防控制中心为33人,全国需要配置140016人;按未来10年内公共职能落实程度计,省级疾病预防控制中心人力配置标准为386人,市级疾病预防控制中心为112人,县级疾病预防控制中心为38人,全国需要配置159086人。结论无论是何种人力配置标准,都意味着现有人力配置数量的大幅度削减,精简人力、提高素质是疾病预防控制中心人力配置的必然趋势。     

不同诊断标准对上海市浦东新区40岁以上社区人群糖代谢类型分布的影响

目的比较不同诊断标准对社区自然人群糖代谢类型分布的影响。方法抽取2002年上海市浦东新区社区自然人群糖尿病调查数据库中40岁以上人群1716例,分别按照1999年世界卫生组织(WHO)和 2003年美国糖尿病学会(ADA)糖尿病诊断标准划分人群糖代谢类型。结果 40岁以上人群中,糖尿病患病率为 10．4％。与WHO标准相比,ADA标准所诊断的糖调节受损患病率升高8．9％(从21.3％至30．2％),而正常葡萄糖耐量下降8．9％(从68．3％至59．4％)。ADA标准新确定的空腹葡萄糖受损与正常葡萄糖耐量比较,其体重指数(40～49岁)和腰臀比(50～59岁)明显增加,而与WHO标准确定的空腹葡萄糖受损的差异无显著性。结论上海市浦东新区40岁以上社区自然人群糖代谢异常患病率较高,不同诊断标准对糖代谢类型比例有明显的影响,ADA新的诊断标准比WHO标准更有利于早期发现高危糖尿病人群。     

Overview Of Stability Study Designs

Stability requirements for the worldwide registration of pharmaceutical products have changed dramatically in the past few years. A series of guidelines on the design, conduct, and data analysis of stability studies of pharmaceuticals have been published by the International Conference on Harmonization (ICH); however, the statistical discussion on study design is limited. In this paper, stability designs including full, bracketing, and matrixing designs will be exemplified. The statistical aspects of these stability designs will be discussed in relation to the recent ICH guidelines. The statistical and regulatory considerations on the selection of stability design will also be presented. The stability study should be well designed so the shelf life of the drug product can be estimated with a high degree of accuracy and precision. Several commonly used criteria for design comparison will be presented. Finally, a case study is presented to illustrate the potential problems of an overreduced design from the statistical and regulatory perspectives.

     

A new concept for the non-invasive treatment of Adolescent Idiopathic Scoliosis: The Corrective Movement© principle integrated in the SpineCor System

Purpose. To evaluate the change in spinal curvature and posture of Idiopathic Scoliosis patients when a curve specific ‘Corrective Movement^© Principle’ (CMP) is applied.

Methods. This prospective interventional study was carried out on a group of 639 patients (92.3% females) having idiopathic scoliosis treated with the SpineCor brace. All girls were premenarchal or less than 1 year postmenarchal. Assessment of brace effectiveness followed the SRS outcome criteria for bracing. The clinical, radiological and postural evaluations assisted to define the patient classification, which guided the unique application of the CMP to each type of curvature.

Results. A total of 583 patients met the outcome criteria. Overall, 349 patients have a definitive outcome. Successful treatment was achieved in 259 (74.2%) of the 349 patients from the fitting to the weaning of the brace. Some 51 immature patients (14.6%) required surgical fusion while receiving treatment. Eight mature patients out of 298 (2.7%) required surgery within 2 years of follow-up beyond skeletal maturity.

Conclusion. The SpineCor brace is effective for the treatment of adolescent idiopathic scoliosis. Moreover, positive outcomes are maintained after 2 years because 151 (93.2%) of 162 patients stabilized or corrected their end of bracing Cobb angle up to 2 years after bracing.
