摘　　要：目的探究榆林地区气象因素与慢性阻塞性肺疾病(COPD)急性加重的关系。方法回顾性分析2019年1月至2020年1月经榆林市第一医院治疗的200例COPD急性加重患者的临床资料以及入院期间榆林地区的气象情况(日平均气温、日平均气压、日平均相对湿度、日平均温极差、日平均日照时间、日平均风速)。分析患者的菌群分布及不同季节COPD急性加重患者的病菌检出情况;采用Spearman相关分析法分析气象因素与COPD急性加重的相关性。结果革兰阴性细菌的株数分布率为53.00%,革兰阳性细菌株数分布率为19.00%,真菌株数分布率为28.00%;春季COPD急性加重患者的细菌阳性率、革兰阴性感染率明显高于夏季、秋季和冬季的患者,差异具有统计学意义(P<0.05),而四季的革兰阳性细菌感染率及真菌感染率比较差异无统计学意义(P>0.05);榆林地区COPD急性加重入院率与日平均气温、日平均湿度、日平均日照时间呈负相关(r=-0.467、-0.326、-0.374,P<0.05),痰细菌培养阳性检出率与日平均气温、日平均湿度呈负相关(r=-0.635、-0.552,P<0.05);呼吸衰竭发生率与日平均气压、日平均温极差呈正相关(r=0.216、0.564,P<0.05),与日平均气温、日平均日照时间呈负相关(r=-0.519、-0.362,P<0.05);COPD患者的急性加重入院率、痰细菌培养阳性检出率及呼吸衰竭发生率与日平均风速无相关性(r=-0.409、-0.196、-0.121,P>0.05)。结论COPD急性加重与该地区气象因素密切相关,其中以日平均气温、日平均湿度、日平均气压、日平均日照时间最为显著。急性加重时病原菌检出阳性率最高的季节为春季,以革兰阴性细菌为主。Objective To explore the relationship between meteorological factors and acute exacerbation of chronic obstructive pulmonary disease(COPD)in Yulin region.Methods A retrospective analysis was conducted on the clinical data of 200 patients with acute exacerbation of COPD treated at the First Hospital of Yulin from January 2019 to January 2020,along with the meteorological conditions in Yulin during their hospitalization(daily average temperature,daily average atmospheric pressure,daily average relative humidity,daily average temperature difference,daily average sunshine duration,daily average wind speed).The distribution of bacterial communities in patients and the detection of bacteria in patients with acute exacerbation of COPD in different seasons were analyzed.Spearman correlation analysis was used to analyze the correlation between meteorological factors and acute exacerbation of COPD.Results The distribution rate of Gram-negative bacteria,Gram-positive bacteria,fungi was 53.00%,19.00%,28.00%,respectively.The bacterial positive rate and Gram-negative infection rate of patients with acute exacerbation of COPD in spring were significantly higher than those in summer,autumn,and winter(P<0.05).There was no statistically significant difference in the infection rates of Gram-positive bacteria and fungi among the four seasons(P>0.05).The admission rate of acute exacerbation of COPD in Yulin area is negatively correlated with daily average temperature,daily average humidity,and daily average sunshine time(r=-0.467,-0.326,-0.374,P<0.05),while the positive detection rate of sputum bacterial culture was negatively correlated with daily average temperature and daily average humidity(r=-0.635,-0.552,P<0.05).The incidence of respiratory failure was positively correlated with daily average air pressure and temperature range(r=0.216,0.564,P<0.05),and negatively correlated with daily average air temperature and daily average sunshine time(r=-0.519,-0.362,P<0.05).The acute exacerbation admission rate,positive sputum bacterial c
