【摘要】 目的:探讨儿童哮喘发作与鼻病毒感染的关系。方法:采用逆转录聚合酶链反应(RT-PCR)方法对72例哮喘发作期患儿进行鼻病毒(RV)检测,并进行不同年龄组病原分布情况比较,同时设立健康对照组。结果:72例哮喘发作期患儿中检出RV阳性病例29例(27.8%),与健康对照组相比差异有显著性;3岁以上年龄组RV感染率为51.9%(27/52),明显高于3岁以下组,两者差异有显著性。结论:小儿哮喘发作与RV感染密切相关,RSV是诱发3岁以上哮喘发作的主要因素。更多还原

【Abstract】 Objective To explore the relationship of rhinovirus(RV)with asthma exacerbation in children.Method To detect the RV frequently irritate acute respiratory tract infection in children in72cases with asthma exacerbation by reverse tran-scription-PCR(RT-PCR).Results Evidence of RV were obtained in29cases(27.8%)of the group of asthma exacerbation,in the group of >3years,27cases were found positive(51.9%),a significant difference was found in the two groups of different ages.Conclusion27.8%of the asthma attacks in children were precipitated by acute RV infections,the ratio in>3years was51.9%,RV was the most common agent in asthma exacerbation of >3years.更多还原
