摘　　要：目的探讨PM2.5浓度对老年慢性支气管炎急性发作的影响。方法选择北京市城市中心区及其他地区的患者资料,监测并记录每日医院周围大气细颗粒污染物PM2.5和PM10的浓度以及平均气温、最高气温、最低气温、风速、相对湿度、气压、能见度等7项气象因子。记录两地区每日老年慢性支气管炎急性发作患者例数。结果 1每日住院的老年慢性支气管炎急性发作患者例数同PM2.5浓度呈正相关,同平均气温、最高气温、最低气温均呈负相关,且与最低气温相关度更大;同气压、相对湿度、风速及能见度均呈负相关。2老年慢性支气管炎急性发作患者例数随PM2.5等级升高而增多。结论老年慢性支气管炎急性发作受PM2.5浓度影响,PM2.5浓度监测对老年慢性呼吸系统疾病急性发作具有预警作用。Objective To investigate the effect of PM2.5 concentration on acute onset of chronic bronchitis. Method The clinical data of Beijing city center and other areas were selected to monitor and record daily fine particulate air pollution around the station PM2.5, PM10 concentrations, and the average temperature, maximum temperature, minimum temperature, wind speed, relative humidity, barometric pressure, visibility seven meteorological factors. The number of cases of chronic bronchitis in patients with acute exacerbation everyday was recorded. Result ①Daily hospital visits attack was positively correlated with the concentration of PM2.5, with the average, maximum and minimum temperatures were negatively correlated, and the minimum temperature associated with relatively greater;same barometric pressure, relative humidity, wind speed and visibility were negatively correlated.②The number of acute exacerbation of chronic bronchitis as PM2.5 level increased and growth. Conclusion Acute exacerbation of chronic bronchitis affected by the concentration of PM2.5, PM2.5 concentration monitoring can play a role in early warning of the onset of senile acute and chronic respiratory diseases.
