目的:本项目旨在探讨空气质量指数(AQI)与空气质量,6种空气污染物的浓度,以及扬州鼻出血的发病率。此外,为鼻出血的防治提供参考信息。方法:收集2017年1月至2021年12月扬州大学附属苏北人民医院收治的鼻出血患者资料。此外,当地AQI和6种空气污染物的浓度,即颗粒物(PM2.5,PM10),二氧化硫(SO2),二氧化氮(NO2),一氧化碳(CO),臭氧(O3)在发病时进行了分析。此外,分析了与鼻出血发生率的相关性。结果:2017年至2021年,鼻出血患者24,721例,年龄在0至17岁之间,男性患者多于女性。4月份发病率较高,May,和六月。不同月份及AQI条件下每日鼻出血次数差异有统计学意义(P<0.05)。Spearman相关分析表明,每天鼻出血的数量与AQI浓度呈正相关,CO,扬州市NO2、O3、PM2.5、PM10、SO2,其中O3、PM10和SO2与平均每日鼻出血数高度相关,大气污染物对鼻出血没有明显的时滞效应。结论:扬州地区鼻出血多见于男性,主要发生在0到17岁,与季节性。扬州市鼻出血发生率与大气污染物呈正相关。因此,通过降低日常生活中的AQI指数,降低空气中环境污染物的浓度,可以在一定程度上预防和减少鼻出血的发生。
Objectives: This project aims to explore the relationship between the air quality index (AQI), the concentration of 6 air pollutants, and the incidence of epistaxis in Yangzhou. Also, to provide reference information for the prevention and treatment of
epistaxis. Methods: Data of patients with
epistaxis admitted to the Northern Jiangsu People\'s Hospital Affiliated to Yangzhou University from January 2017 to December 2021 were collected. In addition, the local AQI and the concentrations of 6 air pollutants, namely particulate matter (PM2.5, PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), and ozone (O3), were analyzed at the time of onset. Furthermore, the correlation with the incidence of
epistaxis has been analyzed. Results: From 2017 to 2021, there were 24,721 patients with epistaxis aged from 0 to 17 years old while male patients were more than females. The incidence was higher in April, May, and June. There was a statistically significant difference in the number of daily
epistaxis in different months and under AQI conditions (P < .05). Spearman\'s correlation analysis showed that there was a positive correlation between the number of daily epistaxis and the concentrations of AQI, CO, NO2, O3, PM2.5, PM10, and SO2 in Yangzhou, in which O3, PM10, and SO2 were highly correlated with the average number of daily epistaxis, and there was no obvious time lag effect of air pollutants on
epistaxis. Conclusion: Epistaxis in the Yangzhou area is more common in males, mostly occurs in 0 to 17 years old, with seasonal. There was also a positive correlation between the incidence of epistaxis and air pollutants in Yangzhou. Therefore, by reducing the AQI index in daily life, and reducing the concentration of environmental pollutants in the air, the occurrence of epistaxis could be prevented and reduced to a certain extent.
