Objective:
To evaluate the effects of exposure to ozone (O3) on sperm quality during different stages of spermatogenesis.
Methods:
All 1 780 subjects attending to the Reproductive Medicine Center in Renmin Hospital of Wuhan University were recruited from April, 4, 2013 to June, 30, 2015. The subjects were living in Wuhan more than 3 months before attending to the program, aged 20 to 40 years. Semen quality (sperm concentration and sperm count) were measured according to standardized protocols. Corresponding daily 8 hours average concentration of O3, other polluted concentration, average temperature and relative humidity were collected in different time, including lag 0, 10, 70 and 90 d, and lag 0-9 d, lag 10-14 d, lag 70-90 d and lag 0-90 d. After controlling the age, BMI, education level and other confounders, generalized linear Model was used to investigate the association between O3 and sperm quality during different stages of spermatogenesis.
Results:
Average daily concentration of O3 during the study period was (114.20±74.88) μg/m3 and the mean values of sperm concentration and count were (76.32±50.17) millions/ml and (164.77 ± 133.05) millions/sample, respectively. Exposure to O3 was associated with decreasing sperm concentration and count. For every 1 μg/m3 increase of O3, the decrease of sperm concentration during lag 10, lag 0-9 and lag 10-14 days exposure windows were 0.040 (95% 50 and ≥

Objective:To investigate the level of self-compassion among residents and related influencing factors, and to help them improve self-compassion ability, achieve learning goals, and increase the degree of satisfaction with learning.Methods:In July 2022, the random sampling method was used to select 330 residents (postgraduate students majoring in clinical medicine after national unified recruitment) from two grade A tertiary hospitals in Shenyang of Liaoning province in China, and Self-Compassion Scale was used for investigation. SPSS software was used to analyze the degree of satisfaction with industry, learning pressure, the balance between learning and life, and occupational burnout among residents and their association with the level of self-compassion through the chi-square test, the one-way analysis of variance, and the multilevel regression analysis.Results:The residents had a mean self-compassion score of (40.90±6.81), and the residents of the second grade had a lower level of self-compassion than those of the other grades. Major satisfaction and balance between learning and life were positively correlated with self-compassion, and occupational burnout was negatively correlated with self-compassion.Conclusion:There is a relatively insufficient level of self-compassion among residents, and improving self-compassion level may effectively regulate occupational burnout, professional satisfaction, and the balance between learning and life, thereby helping to improve learning and mental health.

Objective To evaluate the association between cold spells and nonaccidental mortality from 2001 to 2011 in the Jiang'an District of Wuhan, China. Methods We collected mortality data for December 2001 to 2010 and January to March 2002 to 2011 in the study area. According to the International Classification of Diseases, we stratified the mortality data into three cause-specific categories:nonaccidental mortality, cardiovascular mortality, and respiratory mortality. We also obtained meteorological data (from the China Meteorological Administration) and ambient pollution data (from the Wuhan Environmental Monitoring Center) during the same periods. In the present study, a cold spell was defined as 5 or more consecutive days with daily average temperatures below the 5th percentile of daily mean temperatures (2.58℃) from January to December in 2001-2011. A distributed lag nonlinear model (DLNM) was applied to assess the acute effect of cold spells on daily nonaccidental mortality. Results During the study period, the total number of nonaccidental deaths was 17 119, including 9 403 (75.5%) among individuals aged over 65 years; 7 968 (46.5%) people died of cardiovascular disease. According to this definition, there were a total of 13 cold spell events and 111 days of duration in Wuhan during the study period. Study days were divided into three periods: non-cold spell days, 2008 cold spell days, and cold spell days in other years. Average daily mean temperatures of the above three periods were(8.2±4.5),(-0.7±1.4), and(0.8±1.2)℃, respectively, corresponding to average daily deaths of 14.0 ± 4.2, 18.2 ± 4.5, and 14.9 ± 4.9 for nonaccidental mortality. After adjusting for long-term trends, seasonal trends, weekdays, holidays, and relative humidity, analysis by the DLNM revealed that cold spells were associated with increased mortality risk, with a cumulative relative risk (RR) of 1.56 (95%CI:1.36-1.79) at lag 0-27 days in 2008, higher than that in other years with 1.23 (95%CI:1.08-1.41). Cold spells were not significantly associated with respiratory mortality and people under 65 years of age;however, during the 2008 cold spell RR increased to 1.96 (95%CI:1.62-2.37) and 1.67 (95%CI: 1.43-1.95) for cardiovascular mortality and older adults (≥65 years old), respectively;both males and females had high mortality risk, with RRs of 1.60 (95%CI:1.33-1.92) and 1.50 (95%CI: 1.23-1.84), respectively. The association between cold spells and mortality remained nearly unchanged with and without adjustment for ambient pollutants (PM10, SO2, and NO2) in the DLNMs. Conclusion In Wuhan, both the 2008 cold spell and cold spells in other years were significantly associated with increased nonaccidental mortality. People with cardiovascular disease and elderly adults may be more susceptible to the impact of cold spells on mortality.
