The major aeroallergens in Guangxi, China

Over a 2-year period we have identified pollen grains from 48 families of grasses, as well as mould spores and mite particles during air sampling in Guangxi Province. The major aeroallergens were Artemisia, Moraceae and Euophoribiacea, and the spores of Aspergillus, Penicillinum, Cephalosporium and Helminthosporium. Mites were probably also one of the major outdoor aeroallergens. Our investigations also included inspection of the vegetation of the geographical area involved, as well as skin testing on 774 subjects using extracts of 37 aeroallergens. We believe that this work has provided fundamental information on seasonal allergy in Southern China and South-east Asia.     

某部队急性腹泻病监测报告 Ⅰ.流行病学部分

１９９１年６月～１９９２年５月在驻粤某部队进行了急性腹泻病的主动监测。年发病率为０．６４～１．０次／人／年。发病率与相对湿度（Ｘ２）、气温（Ｘ３），特别是雨量（Ｘ１）的关系经多元回归分析表明呈正相关。ｙ＝１．９８＋０．０２ｘ１＋０．０２ｘ２＋０．０７ｘ３，ｒ＝０．８７２７，Ｐ＜０．０１。病例－对照研究结果提示，饭前、便后不洗手等生活习惯用腹泻发病有密切关系。２６．３％的患者有淋雨、腹部受凉或感冒等     

Research on rapid identification of auto-microbiology system for pathogenic yeast.

The auto-microbiology system yeast biochemical card (AMS-YBC; Vitek System, Inc.) was studied in 77 clinical isolates and 50 laboratory kept isolates on the basis of routine identification. Results of 123 isolates were obtained in 24 hours, while that of the other 4 in 48 hours. 122 (96.1%) were coincidently identified with AMS and routine method. The results suggest that AMS is a rapid, accurate and simple identification method for common pathogenic yeast.

     

颅颌面形态有限元分析系统的初步建立

初步建立一个用于颅颌面形态变化研究的有限元分析系统。方法：程序用ＢｏｒｌａｎｄＣ语言编写，对临床常用的Ｘ线头颅定位片进行分析，将呆分析的头颅定位片描在硫酸纸上，用图形数值化仪把节点输入计算机。根据有限元分析法的原理，将头颅定位片上的颅颌面结构份割许多三角形单元，用应变张量来描述颅颌面形态变化。     

中学生自我差异和心理健康的关系

目的 分析中学生自我差异与心理健康的关系。方法 采用自行修订的自我差异量表和SCL—90对500名中学生进行调查。结果 初中生现实自我与理想自我的差异（AI）和现实自我与应该自我的差异（AO）这两类自我差异分数都显著高于高中生。中学生两类自我差异各因子与心理健康各因子之间都显著相关（P〈0.05）。AI道德自我差异对初中生的心理健康有预测作用;AI心理自我差异与AI自我认同差异对高中生的心理健康有预测作用。结论 应针对中学生的心理特点,提高其对自我的认识,减少诱发心理问题的因素,促进中学生心理健康。     

Lung cancer and prior tuberculosis infection in Shanghai

In a population-based case-control study of lung cancer in Shanghai involving interviews during 1984-86 with 1,405 cancer patients and 1,495 controls, a significant 50% elevation in the risk of lung cancer, adjusted for cigarette smoking, was observed among persons who had a history of tuberculosis. Among those diagnosed with tuberculosis within the past 20 years, the risk exceeded 2.5-fold. In males the lung cancers tended to occur on the same side as the previous tuberculosis infection. For both sexes, the effect of recent tuberculosis was most apparent for adenocarcinoma and peripheral tumours. No relationship was found between lung cancer risk and the type of tuberculosis therapy, including use of isoniazid. The findings suggest that tuberculosis may predispose to lung cancer, with the association most apparent among recent survivors of the infection.
