Objective To explore the effect of carbon monoxide (CO) and ozone (O3) in the air on the myocardial infarction mortality in Ningbo,Zhejiang province,from 2011 to 2015.Methods The data of daily air quality surveillance and the causes of deaths in Ningbo from January 1,2011 to December 31,2015 were collected and the time series study using a generalized additive model was conducted to evaluate the relationship between the mortality of myocardial infarction and the air pollutants after adjustment for the long-term trend of death,weather conditions,"days of the week" and other confounding factors.Results The daily average concentrations of CO and O3 in Ningbo during 2011-2015 were 0.90 (0.02-3.31) mg/m3 and 82.78 (4-236) μg/m3,respectively.A total of 5 388 myocardial infarction deaths occurred,with a daily average of 3 deaths.In single-pollutant model,an increase of 0.1 mg/m3 in average concentration of CO could increase the risk of myocardial infarction mortality by 1.06％ (95％ CI:0.29％-1.93％) in general population,and by 1.26％ (95％ CI:0.28％-2.24％) in aged people aged ≥65 years in lagged 6 days,but the influence was not significant in people aged ＜65 years.The influence had no significant difference in males,but it increased the risk of myocardial infarction mortality by 1.77％ in females (95％ CI:0.44％-3.13％).In multipollutant model,CO did remain robust after adjusting for other co-pollutants.Whereas the effect of O3 had no significant influence.Conclusion These findings suggested that the increased risk of daily myocardial infarction mortality was associated with the increase of CO concentration,but no such association was found for O3 in Ningbo.

Purpose/Significance The present situation of the talent team construction in the information departments of public hospi-tals of traditional Chinese medicine(TCM)in Guangxi is analyzed to provide references for optimizing the talent team construction in this field.Method/Process Taking the personnel in the information departments of secondary and above public TCM hospitals in Guangxi in 2022 as the research objects,statistical methods such as Wilcoxon rank sum test,x2 test and Spearman correlation analysis are used to an-alyze the distribution of the research objects and discuss the existing problems in talent team construction.Result/Conclusion The aver-age number of personnel in the information departments of secondary and above public TCM hospitals in Guangxi is 4.39,accounting for 0.80％of the total number of employees.The overall quantity is insufficient,and the distribution is uneven among regions and hospital levels.The talent structure of tertiary TCM hospitals is relatively better than that of secondary TCM hospitals.
