Review[Air pollution, climate change and health: from evidence to action].
The adverse effects of air pollution and climate change on human health have already been a major global environmental issue, and the challenges in China are even more severe. In this issue, titled "Air Pollution Climate, Change and Health" , we present a series of articles that reviewed and analyzed the impact of air pollution and climate change on human health systematically, and propose recommendations for the next phase of research. Meanwhile, we introduce the latest achievements of the World Health Organization (WHO) in coping with air pollution and health, summarize the first WHO Global Conference on Air Pollution and Health, and provide evidence-based guidelines for control and prevention of climate change and air pollution in China.

[Short-term effects of household indoor- and outdoor-originating fine particulate matters on heart rate and heart rate variability in chronic obstructive pulmonary diseases patients, Beijing].
Objective: To assess the associations of indoor fine particulate matter (PM(2.5)) from outdoor and indoor sources with heart rate (HR) and heart rate variability (HRV) in patients with chronic obstructive pulmonary disease (COPD) of Beijing. Methods: A total of 40 male patients in a stable stage of COPD were recruited from a hospital in a panel study in Beijing with 5 consecutive days of measurement for each subject. General information and disease history of the participants from questionnaires were obtained prior to the study. ⋯ Each 10 μg/m(3) increase at 12 h outdoor-originated PM(2.5) moving average was associated with 0.7% (95%CI: -2.7%, -1.4%), 0.2% (95%CI: -1.9%, 1.4%), 0.7% (95%CI: -1.4%, -0.1%) and 0.2% (95%CI: -1.3%, 0.9%) reduction in HF, LF, SDNN and rMSSD, respectively (P<0.001). Each 10 μg/m(3) increase at 8 h indoor-originated PM(2.5) and outdoor-originated PM(2.5) moving average was associated with 0.7% (95%CI: 0.4%, 1.0%) and 0.4% (95%CI: 0.2%, 0.6%) increase in HR. Conclusion: Exposure to indoor-originated PM(2.5) was more strongly associations with HRV indices and HR compared with outdoor-originated PM(2.5) in male COPD patients.
