女性服刑人员精神创伤的特征

目的调查女性服刑人员精神创伤的特征。方法在湖南新路职业学校中,采用多级随机整群抽样的原则抽取471个女性服刑人员,分青少年组（年龄≤25岁）和成年组（〉25岁）。运用创伤性生活事件问卷（TLEQ）和访谈相结合的技术评估她们的精神创伤经历。结果（1）90.4%的女性服刑人员至少经历1件创伤性事件,63.7%至少经历3件或以上的多重创伤。青少年组的事件数量多于成年组（平均为4和3件,P〈0.01）。暴力和毒品相关犯罪组的事件数量相当（平均4件）,都多于经济犯罪组（2件）;中学或相当教育程度者的事件数量最多（4件）,大专或以上者最少（2件）;未婚、离婚/丧偶2组经历的事件数量最多（4件）,已婚组最少（2件）,均差异有显著性（P〈0.05）。（2）最多见的创伤类型是机动车祸（46.9%）、目睹家庭暴力（46.1%）和被抢劫（38.9%）。16.7%的女犯在18岁以前遭遇过性虐待。与成年组相比,青少年组经历了更多的创伤类型为被抢劫、目睹被惨打、目睹家庭暴力,以及儿童期性虐待。结论我国文化背景下,女性服刑人员的精神创伤经历相当普遍,是精神创伤的潜在受害者。     

医学生营养知识与膳食状况调查

Haemophilia in the developing world: successes,frustrations and opportunities

Summary. There is a need to bridge key gaps between high‐ and low‐income countries and individuals; between health policy and clinical practice; and between producers and users of healthcare technology and scientific evidence. The objective of this report was to perform a diagnosis of the situation in the developing world through a survey. This survey was conducted to gather specific information on various aspects related to haemophilia. Countries were chosen by their comparability in infant and adult mortality rates according to the regionalization proposed by the World Health Organization. These indicators are very sensitive to socioeconomic conditions, and have been widely used to study health inequalities. All regions, except Africa and the East Mediterranean, were represented. Africa was excluded because its indicators were not comparable. The East Mediterranean was not represented because of difficulties in contacting investigators. Twenty‐one country representatives were contacted, and 11 answered the questionnaire. Successes obtained by developing countries are based more on the skills and creativity of the local professionals than on the availability of state‐of‐the‐art technology. Frustrations were related to disease underregistration and the limited availability of treatment products. Haemophilia care in the developing world is not as fair as we would like it to be. Governments do not always cover treatment costs, and a very small percentage of the national health budgets is alotted to haemophilia care. The role of the World Federation of Hemophilia was considered crucial by all the investigators surveyed. Training programmes and supply of factor concentrates were the main contributions identified by the respondents.     

广西武鸣华侨农场心血管病危险因素的调查研究

对广西武鸣华侨农场4158人进行基线普查,410人进行膳食调查和作8小时夜尿电解质测定,并将高血压低发区广西的资料与高发区的北京作对比.结果显示,体重指数高是高血压一个重要的危险因素,而体重过重又与膳食中摄入碳水化合物和总热量大有关.另一主要的危险因素是钠,膳食中摄入钠高,尿Na和Na/K比值高者,血压水平和高血压的患病率亦高.     

门诊抗菌药物使用调查

The practice of breast self-examination results in the earlier detection and better clinical course of Japanese women with breast cancer

Using a questionnaire survey, we analyzed the relationship between the frequency of breast self-examination (BSE) and the clinical stage and course of breast cancer in Japanese patients. BSE had been performed monthly by only 5.4% of the patients (M group), occasionally by 35.4% (O group), and not at all by 59.2% (N group). There was a positive relationship between more frequent BSE and an earlier clinical stage, the percentages of Tis/stage 0 and I for the M, O, and N groups being 83%, 44%, and 36%, respectively (P<0.05). The mean maximum tumor diameters for the three groups were 1.7cm, 2.5cm, and 3.0cm, respectively. The tumor size in the M and O groups was significantly smaller than that in the N group atP<0.01 andP<0.05, respectively. The percentages of patients in the M, O, and N groups who underwent breast-conserving therapy were 42%, 11%, and 19%, respectively, with patients who had performed monthly, BSE more frequently undergoing breast-conserving therapy (P<0.05). At a median follow-up time of 34 months, 0%, 3.8%, and 7.6% of the patients from the M, O, and N groups, respectively, had died of breast cancer, the overall survival curve of the M group being significantly better than that of the N group (P<0.01). This retrospective study suggests the positive correlation of BSE frequency with earlier detection, and a more favorable clinical course in Japanese breast cancer patients.
