中文摘要:
      人群归因分值(人群归因危险度百分比,PAF)是广大流行病学工作者熟悉的公共卫生学指标.PAF的计算主要根据某个危险因素对某病的相对危险度(RR)和人群中该危险因素的暴露比例(Pe).文中介绍由RR和Pe估计PAF列线图的制作方法,以便快速简捷地估算PAF。
英文摘要:
      Objective To establish a rapid method for testing drug sussceptibility on Mycobacterium tuberculosis.Methods Taking absolute Concentration method for drug susceptibility testing of M.tuberculosis as the"gold standard",we examined the drug-resistant of M.tuberculosis strain with nitrate reducrase assay (NRA) and the drug-resistant of M.tuberculosis germ in sputum with NRA. Results NRA and absolute concentration method was basically comparable with NRA susceptibility as 96.5% and the specificity was 100%,When comparing with traditional absolute concentration method, NRA could shorten the time about 3 weeks.Using NRA to test the drug-resistant of M.tuberculosis germ in sputum,its susceptibility was more than 66.7% and specificity was 100%,within 10-20 days. Conclusion NRA could be used as a rapid drug susceptibility testing on M.tuberculosis.
