目的分析阳新县2011年-2013年活动性肺结核患者痰标本的性状、留痰时间对检测结果的影响,了解活动性肺结核患者涂阳人群分布特征,为快速发现传染性肺结核,有效控制结核病提供科学依据。方法根据《中国结核病防治工作指南》的实验方法,对痰标本直接涂片、采用萋-尼氏染色法进行染色,光学显微镜镜检。结果不同性状的痰标本及留痰时间对抗酸杆菌阳性检出率有影响;涂阳患者在年龄、职业的分布有差异。结论干酪痰阳性检出率最高,血痰次之,唾液最低。清晨痰阳性检出率高于夜间痰、即时痰。涂阳患者的年龄分布主要以老年为主,15岁~24岁年龄组的青少年次之;职业分布主要以农民为主。
Objective To analyze the influence of the sputum samples of sputum specimens from patients with active pulmonary tuberculosis in Yangxin County from 2011 to 2013 on the detection results and understand the distribution characteristics of smear positive people in patients with active pulmonary tuberculosis and to provide scientific information for rapid detection of infectious pulmonary tuberculosis and effective control of tuberculosis in accordance with. Methods According to the experimental method of “Guidelines for Tuberculosis Prevention and Control in China”, sputum samples were smeared directly and stained with 萋 -Nihs stain and examined with light microscopy. Results The sputum samples with different traits and sputum retention time had an impact on the positive detection rate of acid-fast bacilli. There were differences in the age and occupational distribution of smear-positive patients. Conclusions The positive rate of sputum positive in cheese is the highest, followed by sputum in sputum and the lowest in saliva. Positive sputum sputum positive detection rate higher than night sputum, instant sputum. The age distribution of smear-positive patients mainly dominated by old people, followed by adolescents aged 15-24 years. The occupational distribution was mainly dominated by peasants.
