Objective To examine the epidemiology of kidney stone in Pudong New Area ofShanghai and analyze its risk factors. Methods 12 565 residents with the age above 16 years weresurveyed. All subjects needed to answer a questionnaire concerning their sex,age,geographic loca tions,occupation,education status and family history of renal calculi,etc. Ultrasound examinationwas used to diagnose the kidney stone. Results The average prevalence of kidney stone was 3.15%(396/12565),4. 05%(247/6096)in the men and 2.30%(149/6469) in the women,respectively (P<0. 05). The prevalence increased significantly with age of men,whereas the prevalence was highest forwomen aged 50-59. The prevalence between city and rural was not significantly different before age60 (2.58% vs 2. 62%,P>0. 05),whereas the prevalence were significantly different after age 60(6.28% vs 3.36%,P<0.05). The prevalence of subjects with a family history of renal calculi washigher than that without family history (32.02% vs 2.06%,P<0. 01). The prevalence in manage ment staff and vehicle drivers were the highest. Conclusions The prevalence of kidney stone in Pud ong New Area of Shanghai was lower than that in south of China. The relative risk increased in sub jects of aged men,women aged 50 59,with family history of renal calculi,management staff and ve hicle drivers. An understanding of the epidemiology particularly the interactions among different fac tors,may help lead to approach that reduce the risk of stone formation.

Building a strong public health system has become an urgent task in the new era. Based on more than eight years of systematic research， we believe that five aspects need to be prioritized for a strong system. First， we should change the perspective on public health， using the word “gonggong jiankang” to replace “gonggong weisheng” and the word “gonggong jiankang tixi” to replace “gonggong weisheng tixi”， to lead the public health system development. Second， we should develop a suitable public health system and continuously improve the health capacity for governance. Third， we should make it clear that the goal of building a strong system is not far-fetched， and we need to consolidate the existing institutional advantages of China’s public health system： when encountering major problems， we can maintain a unified goal and mobilize the whole society to cooperate effectively to accomplish the goal. However， we need to make up for shortcomings one by one， especially to solve the key problem of lacking a strong coordination mechanism in daily work. Fourth， we should pursue excellence and consolidate the“suitable” mechanism proven in the process of coping with the COVID-19， so that efficient mechanisms to deal with major issues can be used in routine work， and efforts should be made to consolidate the advantages of prevention and control of infectious diseases and emergency response，so as to achieve the balanced development of regions categories and units.Finally， it is necessary to strengthen the coordination of government and research institutions， in the aspects of technological innovation， talent team building and accurate consulting services， and work together to pursue a suitable and strong system to realize the modernization of the health system and capacity for governance.

ObjectiveTo analyze the changes in the degree of coordination of China's major epidemic prevention and control efforts before and after the outbreak of the Corona Virus Disease 2019 (COVID-19), so as to explore the impact of epidemic prevention and control measures on coordination dynamics. MethodsA total of 3 864 policy documents related to epidemic prevention and control from January 2000 to December 2020 across 31 provinces (autonomous regions, and municipalities) in China were systematically collected. Contents specific to collaborative and cooperative efforts were extracted, and the extent of interdepartmental coordination were quantified to assess the effectiveness of epidemic prevention and control efforts. Wilcoxon signed-rank test was adopted to statistically analyze the differences between the indicators before and after the epidemic. ResultsThe average overall coordination level for major epidemic prevention and control in 31 provinces (autonomous regions, and municipalities) increased from 43.06% to 97.62%, and the average coordination levels in the eastern, central, and western China soared from 42.29%, 37.50%, and 47.46%, to 98.81%, 96.20%, and 97.46%, respectively, with statistically significant differences (all P<0.05). In terms of department categorization, coordination levels in the professional departments and the key support departments peaked at 100.00%, while other support departments rose to 95.43%, with an increase of 77.15%, 181.85%, and 139.89%, respectively, exhibiting noteworthy statistically significant differences (all P<0.001). ConclusionThe scope of coordination departments of China’s major epidemic prevention and control exists a remarkable surge following the COVID-19 outbreak, notable heightened coordination is particularly observed among the key support departments. Future endeavors should prioritize the roles played by diverse departments in epidemic prevention and control, enhancing both the clarity of departmental responsibilities and the effectiveness of interdepartmental coordination.

ObjectiveTo systematically evaluate the public health governance capacity of 40 cities in Jiangsu, Zhejiang, and Anhui Provinces, providing a scientific evaluation basis for building a "Healthy Yangtze River Delta". MethodsA comprehensive collection of policy documents, public information reports, and research literature related to public health governance capacity in Jiangsu, Zhejiang, and Anhui Provinces was conducted, totaling 6 920 policy documents, 1 720 information reports, and 1 200 literature pieces. Based on the evaluation standards for an appropriate public health system established by the research team, the basic status of public health governance capacity was assessed to identify the strengths and weaknesses of the 40 cities. ResultsIn 2022, the public health governance capacity score for the 40 cities in Jiangsu, Zhejiang, and Anhui Provinces was (562.5±38.0) points. In terms of specific areas, the emergency response field received the highest score of (791.4±49.7) points, while the chronic disease prevention and control field received the lowest score of (368.2±29.6) points. The Jiangsu-Zhejiang-Anhui region has largely achieved the strategic priority of health, gradually improved public health legal regulations, and established a basic organizational framework with a solid foundation for information and data infrastructure. However, challenges still need to be addressed, such as unstable government funding for public health, unclear departmental responsibilities, and barriers to information interoperability. ConclusionThe public health governance capacity of the 40 cities in Jiangsu, Zhejiang, and Anhui Province has been at a moderate level, but disparities have still existed across regions and fields. In the future, while continuing to deepen existing advantages, it is essential to accurately identify the causes of problems, establish a long-term and stable investment mechanism, enhance information connectivity mechanisms, further clarify departmental responsibilities, and promote the achievement of the "Healthy Yangtze River Delta" goal.
