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.

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 explore the role of fibroblast growth factor 21 (FGF21) in rats with severe acute pancreatitis-associated acute lung injury (SAP-ALI) and its related molecular mechanisms.Methods:Twenty-four healthy male SD rats were randomly divided into 4 groups (random number, n=6 per group): Control group, SAP group, FGF21 intervention group (SAP+FGF21 group), and autophagy inhibitor group (SAP+FGF21+3-MA group). The SAP model was established by retrograde injection of 3.5% sodium taurocholate into the pancreatic duct. In SAP+FGF21 group, FGF21 10 mg/kg was intraperitoneally injected at 1 hour before modeling. In SAP+FGF21+3-MA group, FGF21 10 mg/kg and 3-MA 20 mg/kg were intraperitoneally injected at 1 h before modeling. Serum amylase activity was detected by biochemical kit. Plasma levels of tumor necrosis factor alpha (TNF-α) and FGF21 were detected by ELISA. HE staining was used to observe the pathological changes of pancreas and lung tissues. Immunofluorescence was used to detect the protein level of FGF21 in lung tissue. Western blot was used to detect the expression levels of autophagy-related proteins in lung tissue. Autophagosomes in lung tissue were observed by electron microscopy. Results:Compared with the Control group, the plasma and lung tissue FGF21 levels in SAP group were significantly decreased (both P<0.001) , severe pancreatic and lung tissue damage, and elevated plasma TNF-α levels ( P<0.001). Western Blot and transmission electron microscopy showed that: The expression of LC3Ⅱ/Ⅰ in lung tissue of SAP group was down-regulated [(0.912±0.052) vs. (0.700±0.135), P<0.001], and P62 protein level was up-regulated [(0.475±0.068) vs. (0.687±0.070), P<0.001] , and reduced autophagosome counts in the SAP group. In contrast, the SAP+FGF21 group showed elevated FGF21 levels (both P<0.01), attenuated pancreatic and lung injury ( P<0.001), decreased TNF-α levels [(280.10±49.36) pg/mL vs. (86.32±66.00) pg/mL, P<0.001]. Lung tissue of LC3 Ⅱ/Ⅰ levels increase [(0.700±0.135) vs. (0.853±0.073), P<0.01], P62 protein levels cut [(0.687±0.070) vs. (0.538±0.030), P<0.01] ], and increased autophagosomes and autolysosomes under electron microscopy. Compared with SAP+FGF21 group, the expression levels of FGF21 in plasma and lung tissue in SAP+FGF21+3-MA group were not significantly changed, and the level of autophagy was decreased. Pancreas and lung tissue injury was severe ( P<0.001), Plasma TNF-α level obviously higher [(86.32±66.00) pg/mL vs. (212.90±11.56) pg/mL, P<0.05]. Conclusion:FGF21 may play a protective role in SAP-ALI by up-regulating the level of autophagy.

Objective: To explore the protective effect and mechanism of Rhodiola rosea(Rho) bionic nanomedicine in rats with acute pancreatitis. Methods: Erythrocyte membrane vesicles(EMV) were used as biomimetic nanomedicine coating materials to construct Rho biomimetic nanomedicine. Meanwhile, rat models of acute pancreatitis were constructed and divided into acute pancreatitis model(AP) group, Rho group, EMV group and Rhodiola rosea erythrocyte membrane vesicles(R-EMV) group. R-EMV group rats were further treated with NLRP3 activator BMS-986299(R-EMV+BMS-986299 group) and inhibitor MCC950(R-EMV+MCC950 group). The changes of abdominal water volume were observed, and serum levels of interleukin(IL-6), IL-1β, endothelin(ET), diamine oxidase(DAO), malondialdehyde(MDA), superoxide dismutase(SOD) and glutathione(GSH) were detected by enzyme-linked immunosorbent assay(ELISA). Hematoxylin-eosin(HE) staining was used to observe the pathological changes of pancreatic tissue. Immunohistochemistry, reverse transcription-polymerase chain reaction(RT-PCR) and Western blot were used to analyze the expression of NOD-like receptor protein 3(NLRP3) and nuclear transcription factor-Kappa B(NF-κB) in pancreatic tissue. Results: The prepared R-EMVs were nearly circular, the average particle size was(244.61±1.08) nm, and the Zeta potential was-(11.13±1.25) mV. At the same time, the EMV could load(58.67±0.79) μg of Rho. Compared with Sham group, the abdominal water volume of rats in AP group was significantly higher(t=33.79,P<0.01), and the levels of peripheral blood immune indexes IL-1β, IL-6, ET and DAO increased(t=38.25, 42.54, 29.20, 34.92, allP<0.01). In AP group, there were obvious tissue hyperemia and edema, widening of lobular space, infiltration of a large number of inflammatory cells, and increased pancreatic pathological score(t=30.06,P<0.01). Compared with AP group, abdominal water volume, dry-wet weight ratio of pancreas, pathological score, amylase and lipase levels in Rho group decreased(F=1 523.7, 543.3, 839.9, 446.1, 172.2,P<0.05). Compared with other groups, the levels of serum IL-1β, IL-6, ET and DAO in AP group decreased to some extent. Compared with AP group, NF-κB p65 and NLRP3 protein levels and NF-κB and NLRP3 immunohistochemical staining scores decreased in R-EMV group(t=24.54 and 26.91, bothP<0.001). At the same time, the levels of serum IL-1β, IL-6, ET, DAO, MDA, SOD and GSH in R-EMV+MCC950 group were significantly lower than those in AP group, R-EMV group and R-EMV+BMS-986299 group. Conclusion R-EMV has a good pancreatic protection effect in acute pancreatitis, which is related to reducing the activity of NF-κB/NLRP3 pathway and down-regulating the expression of inflammatory factors such as IL-6 and oxidative stress indicators such as MDA.

Objective:To compare the efficacy of unilateral percutaneous kyphoplasty (PKP) and unilateral PKP combined with posterior medial branch block of the contralateral spinal nerve in the treatment of lumbar osteoporotic vertebral compression fracture (OVCF) in the elderly.Methods:A retrospective cohort study was conducted to analyze the clinical data of 161 aged patients with newly developed lumbar OVCF, admitted to Xi′an Central Hospital Affiliated to Xi′an Jiaotong University School of Medicine from January 2019 to January 2023, including 58 males and 103 females, aged 61-88 [(72.9±6.3)years]. All the patients were diagnosed with type II compression fracture based on acute symptomatic osteoporotic thoracolumbar fracture classification (ASOTLF). Seventy-eight patients underwent unilateral PKP (PKP group), while the other 83 patients underwent unilateral PKP combined with posterior medial branch block of the contralateral spinal nerve (PKP+contralateral block group). The operation time, intraoperative blood loss, and length of hospital stay were recorded. Beck index of the injured vertebra, Cobb angle of lumbar lordosis, Roland-Morris disability (RMD) score, visual analogue scale (VAS), and Oswestry disability index (ODI) were evaluated before operation, at 1 day, 1 week, 1 month, 3 months after operation, and at the last follow-up. The incidence of complications such as cement leakage was recorded as well.Results:All the patients were followed up for 6-8 months [(6.7±0.6)months]. There were no significant differences between the two groups in the operation time, intraoperative blood loss, or length of hospital stay ( P>0.05). The Beck index of the injured vertebra and Cobb angle of lumbar lordosis were not significantly different between the two groups before operation, at 1 day, 1 week, 1 month, 3 months after operation, and at the last follow-up ( P>0.05). The RMD score of the injured vertebra, VAS score, and ODI were not significantly different between the two groups before operation ( P>0.05). At 1 day, 1 week, 1 month, 3 months after operation, and at the last follow-up, the RMD scores in the PKP+contralateral block group were (11.23±1.05)points, (10.90±1.11)points, (10.10±1.06)points, (9.94±1.06)points, and (9.60±0.83)points respectively, which were all lower than (17.55±0.71)points, (15.78±0.86)points, (13.42±0.92)points, (10.67±0.78)points, and (9.78±0.72)points in the PKP group ( P<0.05 or 0.01); the VAS scores in the PKP+contralateral block group were (3.02±0.60)points, (2.96±0.55)points, (2.92±0.57)points, (2.88±0.61)points, and (2.70±0.51)points respectively, which were all lower than (3.60±0.57)points, (3.47±0.55)points, (3.32±0.46)points, (2.99±0.47)points, and (2.77±0.42)points in the PKP group ( P<0.05 or 0.01); the ODI values in the PKP+contralateral block group were 14.43±1.29, 14.54±1.24, 14.63±1.32, 14.37±1.31, and 13.42±1.45 respectively, which were all lower than 16.72±1.64, 16.09±1.49, 14.82±1.53, 14.74±1.46, and 13.69±1.75 in the PKP group ( P<0.05 or 0.01). The bone cement leakage rate was 12.0% (10/83) in the PKP+contralateral block group, similar to 11.5% (9/78) in the PKP group ( P>0.05). No other complications such as neurovascular injury, pulmonary embolism or adjacent vertebral fracture were found in either groups. Conclusion:In the treatment of lumbar OVCF in the elderly, unilateral PKP combined with posterior medial branch block of the contralateral spinal nerve is similar to unilateral PKP in terms of the operation time, intraoperative blood loss, length of hospital stay, effectiveness of reduction, and incidence of complications, but it can achieve better pain relief and more satisfactory functional recovery.

It has achieved the overall improvement of the research integrity construction ability of member units of the alliance, organic linkage between government and medical institutions, and efficient combination of internal and external resources, which can provide reference for the research integrity construction of medical institutions in China.

Objective:To evaluate the long-term outcomes and prognostic factors of locally advanced gastric cancer with serosa-invasion.Methods:This study is a retrospective cohort study. The clinical and pathological data of 495 patients with locally advanced gastric cancer with serosa-invasion who underwent laparoscopic radical gastrectomy in Department of General Surgery, the First Hospital Affiliated to Army Medical University from October 2012 to October 2018 was analyzed retrospectively. There were 356 males and 139 females with an age ( M(IQR)) of 59 (16) years (range: 18 to 75 years). Observation indicators included postoperative results and long-term prognosis. The survival curve was drawn by the Kaplan-Meier method. Univariate and multivariate prognostic analysis was performed using the Cox proportional hazards model. Results:Among the 495 patients, a total of 57 patients (11.5%) were lost to follow-up, with a follow-up time of 89 (40) months (range: 23 to 134 months). The 5-year disease-free survival rate (DFS) and the 5-year overall survival rate (OS) were 56.0% and 58.2%, respectively. The 5-year DFS for patients with stage ⅡB, ⅢA, ⅢB, ⅢC were 71.2%, 60.5%, 51.6%, 33.3%, respectively. The 5-year OS for patients with stage ⅡB, ⅢA, ⅢB, ⅢC were 71.2%, 62.2%, 54.1%, 39.3%, respectively. Multivariate analysis showed that age >65 years (DFS: HR=1.402, 95% CI: 1.022 to 1.922, P=0.036; OS: HR=1.461, 95% CI: 1.057 to 2.019, P=0.022), lymph node dissection number less than 25 (DFS: HR=1.348, 95% CI: 1.019 to 1.779, P=0.036; OS: HR=1.376, 95% CI: 1.035 to 1.825, P=0.028), pathological stage Ⅲ (DFS: HR=2.131, 95% CI: 1.444 to 3.144, P<0.01; OS: HR=2.079, 95% CI: 1.406 to 3.074, P<0.01), and no postoperative chemotherapy (DFS: HR=3.127, 95% CI: 2.377 to 4.113, P<0.01; OS: HR=3.768, 95% CI: 2.828 to 5.020, P<0.01) were independent prognostic factors for the decrease in DFS and OS rates. Conclusions:Laparoscopic radical gastrectomy for locally advanced gastric cancer with serosa-invasion could achieve satisfactory long-term oncological outcomes. More lymph node dissection and standardized postoperative adjuvant chemotherapy are expected to further improve the prognosis of patients with locally advanced gastric cancer with serous invasion after laparoscopic radical surgery.
