Objective:To investigate the risk factors for refracture after percutaneous kyphoplasty (PKP) in patients with osteoporotic vertebral compression fracture (OVCF).Methods:A retrospective cohort study was conducted on the clinical data of 149 OVCF patients who were admitted to the First Affiliated Hospital of Soochow University from June 2019 to June 2022, including 21 males and 128 females, aged 56-97 years [(73.2±8.7)years]. Initial surgical segments included T 7 in 1 patient, T 8 in 10, T 9 in 6, T 10 in 6, T 11 in 19, T 12 in 28, L 1 in 38, L 2 in 18, L 3 in 11, L 4 in 7 and L 5 in 5. Patients were divided into refracture group ( n=32) and non-refracture group ( n=117) according to whether they had postoperative refracture after PKP. Refractured surgical segments included T 8 in 2 patients, T 9 in 2, T 11 in 4, T 12 in 5, L 1 in 7, L 2 in 4, L 3 in 6, and L 5 in 2. The age, gender, underlying diseases (hypertension, diabetes), body mass index (BMI), preoperative bone mineral density (BMD), smoking history, drinking history, follow-up time, preoperative visual analogue scale (VAS), and preoperative Oswestry dysfunction index (ODI) of the two groups were recorded. Preoperative paravertebral muscle-related parameters of the two groups were calculated including cross-sectional area of bilateral psoas, bilateral erector spinae, bilateral multifidus, and vertebral bodies, paravertebral muscle mass, and vertebral bone quality (VBQ) score. Univariate analysis was performed to evaluate the correlation between the fore-mentioned indicators and postoperative refracture after PKP in OVCF patients. Multivariate logistic regression analysis was employed to identify the independent risk factors for postoperative refracture after PKP in OVCF patients. Results:Univariate analysis revealed that there was certain correlation of BMI, preoperative BMD, cross-sectional area of bilateral psoas, bilateral erector spinae, bilateral multifidus, paravertebral muscle mass and VBQ score with postoperative refracture after PKP in OVCF patients ( P<0.01), while no correlation was found between age, gender, hypertension, diabetes, smoking history, drinking history, follow-up time, preoperative VAS, preoperative ODI, or cross-sectional area of vertebral bodies and postoperative refracture after PKP in OVCF patients ( P>0.05). Multivariate logistic regression analysis showed that preoperative BMD ≤-3.4 SD ( OR=0.27, 95% CI 0.09, 0.80, P<0.05), paravertebral muscle mass ≤281.2% ( OR=0.98, 95% CI 0.97, 0.99, P<0.01) and VBQ score ≥4.8 points ( OR=4.41, 95% CI 1.18, 16.44, P<0.05) were significantly correlated with postoperative refracture after PKP in OVCF patients. Conclusion:Preoperative BMD ≤-3.4 SD, paravertebral muscle mass ≤281.2%, and VBQ score ≥4.8 points are the independent risk factors for refracture after PKP in OVCF patients.

Proteasome activator PA28γ,also known as Ki antigen,REGγ or PSME3,is first found as Ki antigen in the serum of a patient with systemic lupus erythematosus,which belongs to 11S proteasome activator family together with PA28α and PA28β.In the amino acid sequence,PA28γ has 25%homology with PA28α and PA28β and its seven-subunit homomer is a 20S proteasome acti-vator,which mainly exists in the nucleus and participates in ubiquitin and ATP-dependent or independent protein degradation.More and more studies have reported the role of PA28γ in human immune-related diseases.This article reviews the function of PA28γ as a proteasome activator and its role in immune-related diseases including cancer,inflammation and virus infection-related diseases and other diseases in recent years,so as to reveal the role of PA28γ in the occurrence and development of immune-related diseases and its potential as a target for immunotherapy.

Objective To explore the high-quality development path of tertiary public hospitals and provide scientific reference for deepening the reform of public hospitals.Methods Based on SPO theory,it constructed an analytical framework for the high-quality development of tertiary public hospitals,collected data of a quarterly monitoring in-dex for the performance assessment and high-quality development of tertiary public hospitals in a certain province in 2023,and analysed 73 tertiary public hospitals participating in the performance assessment as the object of analy-sis,and adopted the fuzzy-set Qualitative Comparative Analysis to explore different condition sets of high-quality de-velopment of tertiary public hospitals and reveal the path of high-quality development of public hospitals.Results High-quality development is the result of multi-factor interaction.Four configurations were identified to promote the high-quality development of tertiary public hospitals:service quality-technology-driven path,service quality-driven path,comprehensive service-driven path,and service quality-benefit-driven path.Quality safety and functional orientation were found to be the core elements in promoting high-quality development of public hospitals.Conclusion Hospitals at all levels should strengthen the guidance of party building,combine with the actual functional positioning,take quality and safety as the core,and optimize the combination conditions of technical level,personnel structure,service process,and cost control.It is essential to clarify the development strategy of hospitals,implement the dynamic concept,and realize the high-quality development of public hospitals.

Objective To empirically analyze the status quo of high-quality development of public hospitals in S Province,provides reference for promoting high-quality development of public hospitals.Methods SPSS 26.0 soft-ware and text analysis method were used to process the high-quality development monitoring data of tertiary public hospitals in S Province,and the qualitative interview results obtained by field investigation were comprehensively ana-lyzed.Results In terms of capacity improvement,public hospitals actively take measures such as the construction of medical union and the reform of payment methods to improve their capacity.Specialized hospitals and maternity and child care hospitals need to be improved in some indicators.In terms of structural optimization,the quality of medi-cal services is high in all regions.The proportion of medical service revenue and the proportion of high-grade surgery still need to be increased.In terms of innovation and efficiency improvement,the application level of electronic medi-cal records has made remarkable progress in various regions.There are differences in the funding of scientific re-search projects.In terms of cultural cohesion,patient satisfaction was higher.There is improvement room in the satisfaction of medical staff.Conclusion Third-level public hospitals in S province have achieved certain results in high-quality de-velopment,but there are still problems,such as the need to further integrate party building work with hospital busi-ness work,the lack of connection between performance incentive and performance evaluation index system,and the need to improve the satisfaction of medical staff.It is necessary to solve the problem and improve the quality and efficiency of medical service.

Objective To sort out and quantitatively evaluate the policies of"Internet+Nursing Service",and provide reference for the formulation and improvement of policies.Methods It uses ROST CM 6.0 software to mine the text data of 6"Internet+Nursing service"policies,constructs Policy Modeling Consistency(PMC)index model,and uses 9 first-class variables and 43 second-class variables to quantitatively evaluate the"Internet+Nursing service"policies.Results Among the 6 policies,1 policies were of good grade,5 policies were of acceptable grade,and the mean value of PMC index was 6.40,which was at the level of qualified or above,with higher scores on the primary variables X7 policy tools(0.95),X1 policy nature(0.92)and X9 policy evaluation(0.83),and lower scores on X8 incentive methods(0.63),X2 issuing organizations(0.58),and X5 policy timeliness(0.25).Conclusion The construction of the policy framework of"Internet+Nursing Service"in China is in the exploratory stage,and there is still room for improvement.It is recommended to improve the continuity and standardization of"Internet+Nursing Service"through rational planning of policy timing,comprehensive implementation of division of labour and coordination,and adoption of diversified incentives,etc.,so as to facilitate the high-quality development of public hospitals.
