The influence of home environmental factors and life style on children＇s respiratory health in Xi＇an

To assess associations between home indoor air environments and asthma,allergies and pneumonia,children aged 1–8 years were surveyed from 12 kindergartens in the city of Xi’an.2,020 questionnaires were responded with a response rate of 83.5%.The prevalences of doctor diagnosed asthma,hay fever,and pneumonia were 2.9%,3.6%,and 28.3%,respectively.Living close to a highway was a risk factor for current rhinitis(AOR 1.5,95%CI 1.2–1.8),eczema(AOR 1.7,95%CI 1.2–2.5),and diagnosed pneumonia(AOR 1.3,95%CI 1.0–1.6).Dampness problems in the home were associated with 50%–130%increases in the prevalences of asthma and allergy.Airing bed linen under sun-shine was protective,especially against rhinitis.Pet avoidance was consistently and significantly associated with asthma and allergy(AOR 1.3–2.4).Decoration of the home during children’s early life is a risk factor for current rhinitis(AOR 1.9,95%CI 1.3–2.9)and eczema(AOR 1.9,95%CI1.1–3.6).Risk factors for pneumonia were living in an apartment(AOR 1.4,95%CI 1.1–1.8),latex wall paint(AOR 1.3,95%CI 1.0–1.7),dampness(AOR 1.4–1.5),breast feeding\3 months(AOR 1.3,95%CI 1.0–1.7),never airing bed linen in sunshine(AOR 1.3,95%CI1.3–1.6),and cleaning children’s room less frequently than once per day(AOR 1.4,95%CI 1.1–1.7).This study demonstrates that home indoor environmental and life style factors may influence the health of children in Xi’an.

Mapinfo数据的坐标转换方法研究

本文根据三种方式深入探讨了带属性的MapInfo数据的坐标转换方法：一种通过VC和MapX编程调入“.tab”文件,实现WINDOWS窗口界面化的输入和显示方式,通过输入七参数或四参数,快速实现了坐标系之间的一系列转换;一种通过AutoCAD Map 3D软-导入和导出“.tab”文件,利用平移、旋转、缩放命令实现四参数转换;一种在.prj文件中定义坐标系,通过改变投影来进行转换.这三种方式最终都以WGS-84坐标转换为BJ54坐标为例子进行了验证,取得良好结果.

Biological Applications of Macrocyclic Schiff Base Ligands and Their Metal Complexes: A Survey of the Literature (2005–2019)

This article aims to provide a survey of biological applications of Schiff base macrocycles and their metal complexes, with emphasis given to the synthesis of the compounds and to their uses as antibacterial and antifungal agents. The literature on the subject, published during the 2005–2019 period, is shortly reviewed. This is an informed report collecting information on the addressed topic in a concise systematic way, and can be expected to be useful as a fast literature catalogue for researchers working on this and related domains.     

医疗卫生工作者心理健康水平现状

 为了解医疗卫生工作者心理健康水平的现状，从2017年科技工作者心理状况调查的数据中选取医疗卫生工作者样本1463人，同时抽取其他科技工作者1441人作为对照组。调查结果发现：医疗卫生工作者抑郁风险低于对照组，焦虑和自杀意念与对照组无显著差异，工作倦怠及情感衰竭度显著高于对照组；医疗卫生工作者心理健康群体差异明显，50岁后抑郁和焦虑水平均降低，正高级职称人群的抑郁和焦虑水平均较低。情绪调控方式上，压制组表现出更多的抑郁和焦虑风险；同时，医疗卫生工作者存在睡眠时间不足、运动次数和运动时长不足、工作时长过长的问题；在心理健康服务方面，医疗卫生工作者整体优于对照组。建议改善医疗卫生工作者工作时长和工作压力，倡导健康生活方式，并提高情绪调节能力。     

文科生大学数学学习情况调查研究
