OBJECTIVE: To explore the preparation of nano-silver acupuncture needles and evaluate the appearance, structure and properties. METHODS: Stainless steel acupuncture needles were pretreated by polishing with sandpaper and cleaning with ultrapure water and absolute ethanol. As the working electrodes, the needles were placed in an electrolyte solution contained silver nitrate (AgNO₃), potassium nitrate (KNO₃), and polyvinylpyrrolidone (PVP); and the silver nanoparticles were deposited at a constant voltage of -0.2 V for 1 200 s. The heat-treatment was conducted at 600 ℃ for 15 min in an argon atmosphere to strengthen the adhesion between the nanoparticles and the substrate. The surface appearance and structure of nano-silver acupuncture needles were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The electrical conductivity, thermal conductivity and biocompatibility of the needles were evaluated. The cytotoxicity and biocompatibility of the sample were assessed using the CCK-8 assay. According to the national standard, Acupuncture Needles (GB 2024-2016), the other physicochemical performances of nano-silver acupuncture needles were tested. RESULTS: ①By controlling the AgNO₃ concentration and the molar ratio of AgNO₃ to PVP, it was found that at an AgNO₃ concentration of 2 mmol/L and a molar ratio of 5∶1, silver nanoparticles with the diameter of 50-100 nm, regular appearance, and uniform distribution were obtained. At a lower concentration, the size of silver nanoparticles was smaller and unevenly distributed particles, whereas a higher concentration tended to produce a dendritic structure. ②By sandpaper polishing, acid etching pretreatment, and heat-treatment at 600 ℃ under argon for 15 min, the adhesion of silver nanoparticles on the surface of the needle body was strengthened, and the simulated pig skin puncture test showed the intact coating without shedding. ③SEM found that the silver nanoparticles were uniformly deposited, forming a nanofilm approximately 1.5 μm thick; XRD analysis showed the diffraction peaks corresponding to cubic crystal silver (111), (200), (220) and (311); and XPS detected characteristic peaks of Ag 3d3/2 and Ag 3d5/2, confirming the successful deposition and good crystallinity of the silver nanoparticles. ④Resistivity measurements indicated that the nano-silver acupuncture needles exhibited a resistivity of approximately 0.15 Ω·cm, about three times lower than that of unmodified stainless steel needles. The infrared thermography demonstrated that their thermal conductivity was superior to that of traditional acupuncture needles. In vitro CCK-8 cytotoxicity assay showed that the nano-silver acupuncture needles had no adverse effects on human skin fibroblasts and possessed good biocompatibility. ⑤ The key parameters such as needle tip performance, hardness, and the adhesion between the needle body and handle were in compliance with the requirements in Acupuncture Needles (GB 2024-2016), ensuring a quality guarantee provided for clinical applications. CONCLUSION The preparation of nano-silver acupuncture needles effectively overcomes the insufficient toughness of traditional silver needles and improves the electrical and thermal conductivity of stainless acupuncture needles.

With the continuous development of China's economy,the people expect for higher quality medical services,and medical humanistic care is increasingly emphasized.Under this background,the"Duplex Linkage Mode",which integrates medical social workers and volunteers,has emerged.This paper reviews the current state of applying the mode in China,ex-pounds its benefits,and details its application within hospital services.This application covers guidance for outpatient and emer-gency department,inpatient ward services,hospice care,and community residents volunteer services.In addition,this paper proposes suggestions on furth for optimizing recruitment and training programs,improving management systems,establishing intel-ligent management systems,and improving volunteer support mechanisms.These measures aim to promote the sustainable and healthy development of medical humanistic services and to support the implementation of the Healthy China Initiative.

The development of health-promoting hospitals is an important part of the Healthy China Initiative， facilitating the transformation of medical institutions from a primary focus on medical and surgical treatments to a patient-centered approach prioritizing public health. To promote the scientific， standardized， and sustainable development of health-promoting hospitals， the Shanghai Municipal Center for Health Promotion， together with Shanghai General Hospital and other institutions， has jointly developed the Standards for the Development of Health⁃promoting Hospitals （Standards） in accordance with the principles of scientific rigor， feasibility， and advancing with the times. The Standards outlines the requirements for the development of health-promoting hospitals across four aspects： organizational and institutional guarantees， creation of a healthy environment， implementation of health education and promotion， and evaluation. It is applicable to all levels and types of public medical institutions in Shanghai， and can also be referred to and implemented by other medical institutions. The introduction of the Standards is of great significance for promoting the formation of a long-term mechanism in health-promoting hospitals. This paper introduces the basis， principles， main content， precautions， and implementation suggestions of the Standards. Taking into account relevant policies and standards， it interprets the technical aspects in the process of developing health-promoting hospitals， which is helpful for medical institutions and their management to better understand and apply the standards in their work.

The publication trend showed a " double peak", showing a downward trend. The research hotspots in literature related to medical quality and safety management in China since the new medical reform have focused on practice exploration and influencing factors. The trend of future research is to closely follow the background of the times in medical quality and safety management research and intelligent medical quality and safety management evaluation system research.Conclusions:In the future, research on medical quality and safety management should be more in line with the changes of medical reform policies, focus on high-quality development to deepen the research on micro issues, promote information construction to continuously improve the indicator evaluation system, so as to promote the sustainable and high-quality development of medical quality and safety management in China.

Objective:To construct a theoretical model of medical quality and safety management based on the current situation of medical quality and safety management mode in China, providing reference for continuous improvement of medical quality and safety management.Methods:The CNKI database was used as the data source to search literature, with a high citation index H=38 as the judgment standard, the core literature related to the quality and safety management in China was selected. Based on the structure-process-outcome (SPO) model, Nvivo qualitative analysis software was used to code and analyze the included literature, sort out the relevant elements of China′s medical quality and safety management, and clarify the logical relationship between the elements, forming a generalized SPO model of China′s medical quality and safety management.Results:Through a systematic summary and review of relevant literature, a generalized SPO model for medical quality and safety management was proposed, including 5 structural elements (organizational structure, personnel management, resource management, informatization, management standards), 2 process elements (management methods, service processes), and 3 outcome elements (patient outcomes, employee outcomes, organizational results). The logical relationships between and within the three major elements were constructed.Conclusions:To improve the level of medical quality and safety management in China, the structural dimension should be focused on clarifying the responsibilities of the main body of quality management, establishing an independent and perfect quality control department, strengthening the investment and construction of information technology, and promoting the implementation of the medical quality management standard; the process dimension should be focused on promoting the rational application of quality management tools; and the outcome dimension should be focused on strengthening the management of patient safety and improving the individual satisfaction.

Objective:To systematically construct the foreign medical quality and safety management model by searching the English literature related to medical quality and safety management, so as to provide reference for improving the level of medical quality and safety management in China.Methods:The Web of Science database was used as the data source, the English literature related to medical quality and safety management in foreign countries was screened following the PRISMA guidelines, and the content of the screened literature was analyzed using qualitative text analysis based on the Structure Process System Outcome (SPSO) theoretical model.Results:In this study, a total of 37 articles were screened, 5 first-level themes of structure, process, system, outcome and continuous quality improvement were identified, 16 second-level themes were found, and their functional relationships were established. A theoretical model of the SPSO-Extension (SPSO-E) for medical quality and safety management was constructed, added new elements of the external environment, organizational outcome and employee outcome, and refined the continuous quality improvement into three segments of quality checking, problem handling and quality consolidation.Conclusions:In order to improve medical quality and safety management in China, the internal management model of the hospital should be dynamically adjusted according to the changes of external environment, and the result dimension should pay attention to the improvement of organization′s operational effectiveness and the physiological and psychological aspects of the staff. The final management results have a feedback effect on the hospital′s resource allocation, service delivery, organizational arrangements and cultural construction, promoting continuous improvement and enhancement of the hospital′s quality.

Objective To explore methods to measure the management level of Chinese hospitals in natural conditions of Chinese hospitals, for improvement of their operation efficiency. Methods The methodology of World Management Survey( WMS) was introduced, and the questionnaire was localized using expert consultation method. Double-blind telephone interviews were conducted to investigate the management level of Chinese hospitals in the four dimensions of standardized operation, performance monitoring, target setting and talent management. Results The management level of hospitals in China varied greatly from places. Among them, the hospital management scoring was found to range from 2. 50 to 2. 75 in most cases, averaging 2. 55. These hospitals scored relatively poor at the four specific management practices of hospital layout(2.48), performance communication(2.27), talents retention, and clarity and comparability of objectives(2. 45). Management level of a hospital was correlated to such factors as its history, ownership form, human capital and hospital size. Conclusions This study uses WMS methodology to quantify Chinese hospital management. The overall management level of Chinese hospitals is expected to improve with much gaps to cover. At this stage, it is imperative to solve the unbalanced and inadequate development of hospital management levels, among regions, hospital grades and forms of ownership.
