ObjectiveTo systematically assess the public health governance capacity in Zhejiang Province, to conduct an in-depth analysis of its strengths and weaknesses, so as to provide scientific basis and strategic recommendations for further enhancement. MethodsA systematic collection of policy documents, public information reports, and research literature related to public health governance capacity in Zhejiang Province from 2002 to 2023 was conducted (encompassing a total of 1 263 policy documents, 138 pieces of information reports and 631 research articles). Based on the evaluation criteria suitable for public health systems previously developed by the research team, the basic status and magnitude of change in public health governance capacity in Zhejiang Province was evaluated. Additionally, normative gap analyses were employed to identify the strengths and weaknesses. ResultsZhejiang Province ranked 4th nationwide in terms of public health governance capacity with a score of 733.4 points (1 000.0-point maximum). The province has effectively implemented the principle of health first (scoring 698.5 points in the assessment of health-first strategy implementation) and attached sufficient importance to health-related goals (scoring 658.2 points in the scientific rationality of goal setting). However, the implementation of inter-departmental coordination and incentive mechanisms only scored 178.7 points, the feasibility of management and monitoring mechanisms scored even lower at only 144.0 points, and the coverage of incentive mechanisms scored 286.0 points. ConclusionZhejiang Province has effectively implemented its health first strategy and attached great importance to health targets, but still needs to strengthen cross-departmental coordination mechanisms and health-oriented incentives.

Objective:To analyze the incidence and mortality of pancreatic cancer in China from 1992 to 2021, and to explore the effects of age, period, and cohort on pancreatic cancer incidence and mortality.Methods:Data from the Global Burden of Disease Study (GBD) 2021 database were used to analyze the incidence and mortality of pancreatic cancer in China from 1992 to 2021. The Joinpoint software was applied to analyze the time trends of standardized incidence and mortality rates, and to calculate the average annual percentage change. An age-period-cohort model was constructed to analyze the effects of age, period, and birth cohort on the trends of pancreatic cancer incidence and mortality. The disease burden of pancreatic cancer deaths attributed to risk factors such as hyperglycemia and smoking was analyzed.Results:In 2021, the incidence of pancreatic cancer in China was 8.34/100 000, and the mortality rate was 8.41/100 000, representing increases of 150.45% and 145.19%, respectively, compared to 1992 (3.33/100 000 and 3.43/100 000) . By sex, the incidence (9.93/100 000) and mortality (9.91/100 000) rates in males in 2021 were higher than those in females (6.68/100 000 and 6.83/100 000) . From 1992 to 2021, the standardized incidence and mortality rates of pancreatic cancer in China showed upward trends, with average annual increases of 0.80% and 0.62%, respectively, both of which were statistically significant (both P<0.001) . Age effect results indicated a general increasing trend in pancreatic cancer incidence, with a steady rise in the 15-49 age group, a sharp increase after the age of 50, and a peak in the over 85 age group at 68.64/100 000. The mortality rate showed a slow increase in the 15-79 age group, with a marked rise and peak in the 80-84 age group at 196.51/100 000. Period effect results showed an overall upward trend in the period relative risk ( RR) for pancreatic cancer incidence, with the highest risk in 2017-2021 ( RR=1.09, 95% CI: 1.05-1.13, P=0.012) , compared to the reference period 2002-2006 ( RR=1) . The RR for pancreatic cancer mortality showed a fluctuating trend, with the highest risk in 2012-2016 ( RR=1.60, 95% CI: 1.07-2.38, P=0.021) , compared to the reference period 2002-2006 ( RR=1) . The results of cohort effect showed that the incidence and mortality risk of pancreatic cancer in China generally increased with the increase of years. With the 1952-1956 birth cohort as the reference cohort ( RR=1) , the incidence ( RR=1.18, 95% CI: 0.99-1.40, P=0.032) and mortality ( RR=1.63, 95% CI: 0.12-11.53, P=0.042) risk of pancreatic cancer were the highest in the 1987-1991 birth cohort, and showed decreasing trends after the 1992-1996 birth cohort. The proportion of pancreatic cancer deaths attributable to high blood glucose showed an increasing trend, while those attributable to smoking showed a decreasing trend. Conclusions:From 1992 to 2021, the standardized incidence and mortality rates of pancreatic cancer in China have continued to rise, with males having higher incidence and mortality rates than females. Age, period, and cohort all significantly influence the trends in pancreatic cancer incidence and mortality. The trend in pancreatic cancer deaths attributable to high blood glucose is increasing.

Objective To explore the relative positioning of the superior orbital fissure and internal carotid artery through CT three-dimensional reconstruction,and to provide anatomical references for safe dissection during surgeries involving the orbital apex from a radiological perspective.Methods Totally 64 cases(128 sides)of head and neck CT angiography were analyzed and Mimics 21.0 software was employed for three-dimensional reconstruction.Measurements were taken on the three-dimensional models,including the distance from the inner boundary of the superior orbital fissure to the anterior convexity,proximaldural ring,and distaldural ring of the internal carotid artery.Distances were also measured from the lower boundary of the superior orbital fissure to the anterior convexity,proximaldural ring,and distaldural ring of the internal carotid artery.Additionally,measurements were taken from the upper boundary of the superior orbital fissure to the anterior convexity,proximaldural ring,and distaldural ring of the internal carotid artery.Patient demographic data such as gender,age,and sphenoid sinus aeration were recorded,and anatomical variations were analyzed in correlation with the measured result.Results Distances were measured as follows,d1(6.32±1.98)mm,d2(7.13±2.66)mm,and d3(9.88±2.29)mm from the inner boundary of the superior orbital fissure to the anterior convexity,proximaldural ring,and distaldural ring of the internal carotid artery,respectively.Distances were also measured as d4(11.93±2.17)mm,d5(10.39±2.36)mm,and d6(16.18±2.28)mm from the lower boundary of the superior orbital fissure to the anterior convexity,proximaldural ring,and distaldural ring of the internal carotid artery,respectively.Distances from the upper boundary of the superior orbital fissure to the anterior convexity,proximaldural ring,and distaldural ring of the internal carotid artery were measured as d7(7.91±2.55)mm,d8(9.63±2.99)mm,and d9(10.09±2.72)mm,respectively.The relative distance between the superior orbital fissure and the cavernous segment of the internal carotid artery was significantly greater in males than in females.In patients under 20 years of age,d7-d9 were significantly smaller than in patients over 20 years old,with statistically significant differences.There was a correlation between the type of sphenoid sinus aeration and the main measured parameters d1-d6,while the degree of sphenoid sinus aeration and the presence of the superior orbital fissure were not significantly correlated with the main measured parameters.Conclusion Three-dimensional reconstruction based on CT angiography provides a better assessment of the distance between the superior orbital fissure and internal carotid artery.This method holds clinical reference value for orbital apex surgeries and ensures a safe dissection distance.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.
