Education of dentists in China

China is geographically located in the east of Asia and its population exceeds 1.3 billion. An understanding of dental education in China is thus of interest. However, as there is little published information on this topic, this paper provides information about China regarding its dental history, dental school system including curriculum and dental licensure. High school graduates take a nationwide entrance examination to apply for dental school, of which there are more than 50 in China. A five year dental education leads to the BDS degree. Dental school graduates must then pass the nationwide licensure examination to practise dentistry. Currently, there are not adequate numbers of dentists to provide the necessary oral health care for people living outside metropolitan areas.     

Physical Activity and Sedentary Behaviors among Chinese Children: Recent Trends and Correlates

Objective This study was aimed at examining the trends and correlates of physical activity (PA) and sedentary behaviors among Chinese children. Methods A total of 4,341 subjects (6,936 observations) aged 6–17 years who participated in the China Health and Nutrition Survey (2004–2015) were included. Of the subjects, 41％ participated in the survey twice or more. Random-effects ordinal regression models and repeated-measures mixed-effects models were used to examine the PA trends. Quantile regression models were applied to examine the factors influencing PA and sedentary behaviors. Results From 2004 to 2015, the prevalence of physical inactivity among Chinese children aged 6–17 years increased by 5.5％ [odds ratio (OR), 1.51; 95％ confidence interval (CI), 1.19–1.90; P < 0.001]. The PA volume declined by 5.8 metabolic equivalent of task-hr/week (P < 0.001), and the time spent in sedentary behaviors increased by 1.8 hr/week (P < 0.001). Age, ethnicity, and region showed significant effects on the PA volume across the quartiles (P < 0.001). Across the quartiles, sedentary time was significantly higher in the children residing in urban areas (P < 0.001) or areas with high urbanization levels (P ≤ 0.005) than in their counterparts. Conclusions A declining PA trend among Chinese children aged 6–17 years was observed from 2004 to 2015, and certain subgroups and geographical areas are at higher risk of physical inactivity.

栉风沐雨 春华秋实 中国尿控事业发展历程回顾——纪念《中华泌尿外科杂志》创刊40周年

尿控是泌尿外科学的重要分支学科,也是最为复杂的领域之一。我国尿控领域的科研与临床工作起步较晚、起点较低。近40年来,在全国泌尿界同仁的共同努力下,我国尿控领域在尿动力学、尿失禁、膀胱过度活动症、神经泌尿学、功能泌尿学、盆底功能障碍等领域有了飞速发展,取得了显著进步,但与国际水平相比仍存在一定差距。《中华泌尿外科杂志》一直伴随着中国尿控事业的发展,正值她创刊40周年之际,我们以检索到的杂志发表论文为循证依据展开综述,系统回顾我国尿控事业的发展历程,展示学科建设成果,以兹祝贺《中华泌尿外科杂志》40岁生日,并鞭策激励我国尿控工作者更加努力,共同推动我国尿控事业向更高水平发展。     

Origin and epidemic status of porcine epidemic diarrhea virus variants in China

From 2010, porcine epidemic diarrhea virus (PEDV) variants caused sequential outbreaks of disease in Asia and the United States. In this retrospective study, 49 complete spike (S) gene sequences were obtained from PEDV strains collected in China from 2014 to 2016. We observed that variant PEDV strains with novel insertions, deletions, and multiple S gene recombination types were present in China. In addition, mixed infections involving different variant strains were observed in some areas. Based on phylogenetic and recombination analyses, we determined that the newly emerged PEDV variants potentially originated via recombination between the earliest Chinese G1 genogroup strain, JS‐2004‐2 and earlier Korean pandemic strains. These findings provide important information for understanding ongoing PEDV outbreaks and suggest that novel variants make it more difficult to prevent PEDV infection.     

Description and plasmid characterization of the qnrD determinant in Proteeae in Wenzhou,Southern China
