This study aimed to examine the overall effects of PM10 on EDAs for cardiovascular and respiratory diseases,
including specifically, Cerebrovascular Events (CVE), Ischemic Heart Disease (IHD), arrhythmia, Heart
Failure (HF), Upper Respiratory Tract Infection (URTI), Lower Respiratory Tract Infection (LRTI), Chronic
Obstructive Pulmonary Disease (COPD) and asthma. We collected daily data for EDAs from the 10 largest
hospitals in Beijing, between January 2013 and December 2013 as well as daily measurements of PM10 from
17 stations in Beijing. The generalized-additive model was utilized to evaluate the associations between daily
PM10 and cardio-pulmonary disease admissions. In all, there were approximately 56,212 cardiovascular and
92,464 respiratory emergency admissions presented in this study. The largest estimate effects in EDAs of total
cardiovascular disease, CVE, IHD, total respiratory diseases, URTI, LRTI and COPD were found for PM10
at day 4 (accumulative) moving average, were 0.29% (95% CI: 0.12%, 0.46%), 0.36% (95% CI: 0.11%, 0.61%),
0.68% (95% CI: 0.25%, 1.10%), 0.34% (95% CI: 0.22%, 0.47%), 0.35% (95% CI: 0.18%, 0.51%), 0.34% (95% CI:
0.14%, 0.55%), 2.75% (95% CI: 1.38%, 4.12%) respectively. In two-pollutant models and full-pollutant model
modified confounding factors, the positive correlation remained unchanged. The elderly (age ???65 years) and
male subjects were more susceptible to specific respiratory diseases. PM10???s impact on EDAs for HF was
found higher during the hot season however, EDAs for COPD peaked during the cold season. The study
markedly informed that PM10 pollution was strongly associated with EDAs for cardio-pulmonary diseases.

His main research direction is the effect of air pollution on cardiovascular and cerebrovascular diseases and the longitudinal study analysis of early risk factors of Alzheimer’s disease.
