The burden of disease attributed to the indoor exposure to sulfur dioxide (SO 2 ), nitrogen dioxide (NO 2 ), ozone (O 3 ), and carbon monoxide (CO) is not clear, and the quantitative concentration-response relationship is a prerequisite. This is a systematic review to summarize the quantitative concentration-response relationships by screening and analyzing the polled effects of population-based epidemiological studies. After collecting literature published between 1980 and 2019, a total of 19 health outcomes in 101 studies with 182 health risk estimates were recruited. By meta-analysis, the leave-one-out sensitivity analysis and Egger's test for publication bias, the robust and reliable effects were found for SO 2 (per 10 μg/m 3 ) with chronic obstructive pulmonary diseases (COPD) (pooled relative risks [RRs] 1.016, 95% CI:1.012-1.021) and cardiovascular diseases (CVD) (RR 1.012, 95%CI: 007-1.018), respectively. NO 2 (per 10 μg/m 3 ) had the pooled RRs for childhood asthma, preterm birth, lung cancer, diabetes, and COPD by 1.

This paper conducts a physiological and biochemical regulation analysis on the elite rowers' weekly pre-competition training session, taking Guangdong men's lightweight rowing team as study object. Methods: literature study, expert interview, test and mathematical statistics. Results: Firstly, the weekly training session consists differentdistance rowing on water, core strength training on land with proper load-intensity, which mainly focuses on aerobic training and intensifies training according to the rowers' weak points during the full length rowing; Secondly, the performance in simulation games and the final game indicate the effectiveness of the training with improvement of whole distance rowing results, the rowers' lactic acid indexes rise as their performances improve. Conclusions: the weekly rowing training mode reasonably allocates land training and water training, which proves its effectiveness through analyzing the rowers' physiological and biochemical changes during training sessions and games. This research is applicable to the monitoring of physiological and biochemical index for elite rowers' weekly pre-competition training session.
