ObjectiveTo evaluate the public health governance capacity in Jiangsu Province and provide an optimized pathway for the construction of a “strong, rich, beautiful, and high-quality” new Jiangsu. MethodsA total of 806 policy documents, 658 public information reports, and 148 research literatures related to public health governance capacity in Jiangsu Province from January 1995 to December 2023 were collected. The status of current public health goverance was assessed based on the evaluation criteria suitable for public health systems, and the strengths and the weaknesses of the system were identified. ResultsThe public health governance capability of Jiangsu Province was scored at 738.3 points, ranking 3rd nationally. Maternal health care and emergency response capacities achieved leading positions nationwide, both ranking 2nd. Jiangsu had exhibited a standardized guidance in the strategic level, a well-established management mechanism, an extensive coverage in information collection, and a scientifically established health targets setting. However, bottlenecks remained, including an unclear division of responsibilities across organizational departments, an insufficient public-health workforce, the absence of a stable growth mechanism for government funding investment, and difficulties in promptly identifying public needs. ConclusionJiangsu’s public-health system demonstrates leading nationally, yet several components remain underdeveloped. Future efforts should consolidate advantages while addressing weaknesses, further diversify content and forms, establish a stable funding increase mechanism, and clarify departmental functions, thereby providing solid health support for realizing the developmental goals of a “strong, rich, beautiful and high-quality” new Jiangsu.

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.

This article explores the technological innovations and clinical prospects of robot-assisted hiatal hernia repair (RAHHR). RAHHR demonstrates outstanding performance in hiatal hernia repair, particularly for complex hernias, owing to its advantages such as 3D visualization and 7-degree-of-freedom robotic arms, which contribute to reduced recurrence rates and accelerated recovery. However, challenges remain, including high costs and limited operative space. Future directions include the development of single-port robotic systems, force feedback technology, and AI-powered surgical navigation. Standardized training and technological innovations are expected to promote its widespread application.

[Purpose]To analyze the incidence and mortality of oral and pharyngeal cancer in can-cer registration areas of Hunan Province in 2021 and the trend changes from 2012 to 2021.[Methods]Data on oral and pharyngeal cancer incidence and mortality from 2012 to 2021 were collected from 78 quality-controlled cancer registries in Hunan Province,with population data sourced from household registration statistics provided by public security authorities.Indicators such as crude incidence and mortality rates,age-standardized incidence and mortality rates by Chinese standard population(ASIRC/ASMRC),and world standard population(ASIRW,ASMRW)in 2021 were calculated.The Chinese standard population(2000 national census)and Segi's world standard population were used for standardization.Joinpoint Regression Program 4.9.0.0 software was used to fit a Log-linear regression model,and the average annual percentage change(AAPC)of ASIRC/ASMRC of oral and pharyngeal cancer from 2012 to 2021 was calculated to analyze the changing trends.[Results]In 2021,the crude incidence rate of oral and pharyngeal cancer in cancer registration areas of Hunan Province was 9.28/105(15.14/105 for males and 3.07/105 for fe-males),with an ASIRC of 6.10/105;the crude mortality rate was 3.75/105(6.19/105 for males and 1.16/105 for females),with an ASMRC of 2.16/105.Both the incidence and mortality rates in male were significantly higher than those in female.Age distribution analysis showed that the incidence rate of oral and pharyngeal cancer increased with age after 30 years old,peaking in the age group of 60～64 years old(22.29/105);the mortality rate continued to rise after 35 years old,reaching the peak in the population aged ≥85 years old(14.52/105).Trend analysis from 2012 to 2021 indicated that the crude incidence rate and ASIRC of oral and pharyngeal cancer increased from 3.50/105 and 2.63/105 in 2012 to 9.28/105 and 6.10/105 in 2021,with AAPC of 12.33％and 10.80％,re-spectively;the crude mortality rate and ASMRC also showed upward trends(AAPC of 9.87％and 7.21％,respectively);all trend changes were statistically significant(all P＜0.05).Sex stratification revealed that the AAPC of ASIRC and ASMRC of oral and pharyngeal cancer in male were higher than those in female(AAPC of ASIRC:12.65％for males vs 4.28％for females;AAPC of ASMRC:8.79％for males vs 4.13％for females).Age-specific trend analysis found that the ASIRC of oral and pharyngeal cancer in the population aged ≤ 44 years old showed an upward trend(AAPC=11.73％,P＜0.001),with the AAPC of male in this group reaching 14.57％;the AAPC of ASIRC for the age groups of 45～64 years old and ≥65 years old were 11.03％and 9.74％,respectively,and the AAPC of ASMRC for these two groups were 10.05％and 8.19％,respectively,with all trend changes being statistically significant(all P＜0.05);there was no statistically significant change in the ASMRC of the population aged ≤44 years old(AAPC=5.66％,P=0.087).[Conclusion]The incidence and mortality rates of oral and pharyngeal cancer in cancer registration areas of Hunan Province remain high and show an upward trend,with a tendency of younger onset.Males and middle-aged and elderly populations are the key focuses of prevention and control.

Objective:To investigate the long-term outcomes of using 3D-printed preformed titanium meshes in repair and reconstruction of orbital region.Methods:A retrospective analysis was conducted on patients with tumors invading the naso-orbito-maxillary region who underwent surgical resection and repair/reconstruction with 3D-printed preformed titanium meshes. The patients were collected at three medical centers (the Third Affiliated Hospital of Sun Yat-sen University, Xijing Hospital of Air Force Military Medical University, and Shenzhen Longgang District Ear, Nose and Throat Hospital) from 2016 to 2023. Tumor extent was evaluated radiologically, and the surgical approaches, reconstruction outcomes, surgical complications, and long-term follow-up results were analyzed.Results:A total of 46 patients from the three centers were included in this study, comprising 27 males and 19 females, with an average age of 51 years (range: from 13 to 86 years). Among them, 4 patients had benign tumors, while the remaining 42 had malignant tumors. The median follow-up duration was 60.7 months (range: from 19.0 to 75.0 months). Postoperatively, symmetrical globe position was achieved in 38 cases without significant diplopia; 4 cases exhibited enophthalmos without diplopia, and 4 cases had enophthalmos with diplopia. Twelve patients received preoperative radiotherapy, and 30 patients received postoperative radiotherapy. Six patients developed enophthalmos, and 6 experienced titanium mesh exposure after radiotherapy. Following treatment completion, 3 patients underwent repair using frontal flaps, 1 using a superficial temporal artery island flap, and 2 using free flaps. All remaining patients showed no postoperative infections, and their wounds healed normally.Conclusion:The application of 3D-printed preformed titanium mesh enables precise repair of postoperative defects in patients with naso-orbital tumors, facilitating reliable reconstruction of the orbital and facial contours with straightforward operation and dependable outcomes.

OBJECTIVE To study the anatomic characteristics of the anterior ethmoidal canal(AEC)based on 0.1 mm ultra-high resolution CT.METHODS Nine cadavers(18 side orbits)fixed in 10%buffered formalin were enrolled and underwent U-HRCT and MSCT.Divided AEC into horizontal,superior oblique,and inferior oblique segments and observed the displaying rate of each section.Subjective evaluation of display situation was performed by two experienced radiologists independently.The diameter of each AEC segment was measured.RESULTS No significant difference was found in the display rate of the horizontal and superior oblique segments between U-HRCT and MSCT groups(P>0.05),the display rate of inferior oblique segment of U-HRCT group was significantly higher than MSCT group(P<0.05).There was no significant difference in the objective evaluation results between two evaluators and consistency was strong.Subjective scores of each segment of AEC in U-HRCT group were 10.00 points(9.75 points,10.00 points),2.00 points(2.00 points,3.00 points)and 8.00 points(6.00 points,10.00 points),in MSCT group were7.00 points(5.75 points,8.00 points),2.00 points(2.00 points,2.00 points)and 2.00 points(2.00 points,4.00 points).Subjective scores of horizontal and inferior oblique segments of AEC in U-HRCT were higher than MSCT(P<0.05).The anteroposterior diameter of the horizontal section of AEC is(0.92±0.12)mm,the axial diameter is(1.04±0.22)mm.The anteroposterior diameter of the inferior oblique segment is(0.47±0.08)mm,and the transverse diameter is(0.50±0.06)mm.The anteroposterior diameter of the superior oblique segments is(0.66±0.11)mm,and the transverse diameter is(0.72±0.20)mm.CONCLUSION U-HRCT is better to evaluate AEC than MSCT.It could be used to help to study the anatomic characteristics of AEC before surgery to avoid complications.

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.

OBJECTIVE: To summarize the research progress on knee laxity of biomechanics and prevention and treatment after posterior cruciate ligament (PCL) reconstruction. METHODS: The domestic and international literature on the prevention and treatment of knee laxity after PCL reconstruction in recent years was extensively reviewed and analyzed. RESULTS: Different degrees of knee laxity often occur after PCL reconstruction, which can lead to poor prognosis in patients. The causes are associated with a variety of factors, including abnormal graft remodeling (such as differences in healing time and biomechanics among different types of grafts), tunnel position deviation (such as graft wear caused by the "killer turn" effect), and mechanical factors in postoperative rehabilitation (such as improper early weight-bearing and range of motion). These factors may promote graft elongation, increase early posterior tibial translation, and thereby induce knee laxity. CONCLUSION While PCL reconstruction improves knee stability, it is crucial to focus on and prevent postoperative knee laxity. However, current surgical methods are limited by factors such as graft characteristics, surgical technique flaws, and rehabilitation protocols, and thus can not fully correct the issue of abnormal postoperative laxity. Surgical techniques and treatment strategies still need further improvement and optimization to enhance patients' postoperative outcomes and quality of life.

OBJECTIVE: To summarize research progress on enhanced recovery after posterior cruciate ligament (PCL) reconstruction, clarify the core contradictions, effective intervention methods, and evaluation shortcomings in current clinical practice, and provide theoretical support for optimizing clinical rehabilitation strategies. METHODS: Relevant domestic and international literature in recent years was systematically searched. The key technologies and challenges for enhanced recovery after PCL reconstruction were analyzed from three aspects: the core issues of enhanced recovery after PCL reconstruction, treatment strategies, and the post-reconstruction effectiveness evaluation system. RESULTS: Enhanced recovery after PCL reconstruction mainly faces two core problems. First, there is a balance dilemma between graft tendon protection and knee joint function recovery: the tensile capacity of the graft tendon is weak in the early postoperative period, so excessive weight-bearing easily leads to relaxation, while overly conservative immobilization causes muscle atrophy and joint adhesion. Second, the return-to-sport rate is significantly affected by injury type and treatment method: patients with combined multiple ligament or meniscus injuries have a much lower return-to-sport rate than those with isolated PCL injury, and the risk of return-to-sport failure is higher. Current research mainly promotes rehabilitation from two aspects: physical therapy and surgical technology. Physical therapy runs through the perioperative period: preoperatively, muscle strength training, swelling control, and maintenance of joint range of motion are used to optimize surgical conditions; postoperatively, phased intervention is implemented. Surgical technology focuses on minimally invasive and anatomical approaches: arthroscopic surgery reduces injury, double-bundle reconstruction and internal tension-relief technology improve stability, and modified tunnel positioning and special surgical methods avoid the risk of "Killer Turn". Postoperative functional evaluation adopts multi-dimensional indicators: subjective evaluation relies on scales such as Lysholm and International Knee Documentation Committee (IKDC); objective evaluation assesses stability through Telos stress test and posterior drawer test; imaging evaluation takes MRI as the core; psychological evaluation is assisted by the Tampa scale of kinesiophobia-11 (TSK-11). However, there are obvious shortcomings, such as the lack of PCL-specific evaluation tools. CONCLUSION Enhanced recovery after PCL reconstruction requires the integration of precise surgery, individualized rehabilitation, and comprehensive subjective and objective evaluation. In the future, biomaterials and digital technologies should be integrated to optimize the full-cycle management of PCL reconstruction, thereby improving functional recovery and the effect of return to sports.
