BACKGROUND:Zinc-based alloy medical implant materials have excellent mechanical properties,complete degradability and good biocompatibility,and are mainly used in orthopedic implants,cardiovascular stents,bile duct stents,tracheal stents,nerve catheters,etc. OBJECTIVE:To review the research progress of biodegradable zinc-based alloys in bone defect repair and prospect the promising research direction and achievements of zinc-based materials. METHODS:After searching PubMed,Web of Science,WanFang Data,and CNKI databases from the establishment of the database to June 2023,various relevant articles on biodegradable zinc-based alloys for bone implant material research were collected.The basic characteristics of biodegradable zinc based alloys were summarized,and the role of zinc-based alloys in promoting bone tissue repair was sorted and summarized.The current research hotspots and shortcomings were discussed. RESULTS AND CONCLUSION:(1)Zinc-based alloys have good biocompatibility.Using zinc-based alloys as the matrix material,with the help of scaffold structure construction technology and coating optimization process,the bone conductivity of zinc-based alloys will be effectively improved,and their degradation products will have efficient bone induction to regulate the gene expression of osteoblasts and osteoclasts,thereby promoting the repair and reconstruction of bone defects.(2)However,in the research on optimizing zinc-based alloys,the coating process is relatively insufficient,and additive loading technology is still lacking.(3)Zinc-based alloys have excellent mechanical and biological properties.Through special processes,their bone conductivity and osteoinductivity can be increased to effectively improve their ability to promote bone repair and reconstruction,and it is expected to further achieve the development of personalized transplant materials.Further research and development are needed to optimize the integration of coating and additive loading technologies into zinc-based alloys.

Objective To explore the effectiveness of Failure Modes and Effects Analysis(FMEA)in emergency man-agement of sudden incidents involving outpatient and emergency patients in general hospitals,to provide references for the optimi-zation of emergency response process for such incidents.Methods Based on FMEA,we identified and evaluated risks in the e-mergency response procedures for sudden incidents involving outpatient and emergency patients in general hospitals.Potential fail-ure modes were analyzed to identify key risks with a Risk Priority Number(RPN)greater than 125.Continuous quality improve-ment measures were implemented to control these risks,and the effectiveness of these controls was evaluated using chi-square tests for statistical analysis.Results A total of 16 risk points in 4 major areas were identified.After implementing continuous quality improvement measures,the RPNs of these high-risk points decreased to below 125,effectively controlling the potential risks.This intervention significantly improved the utilization rate of emergency equipment,the timely reporting rate of sudden in-cidents,the timely feedback rate of emergency response,with statistically significant differences(P＜0.01).Conclusion The application of FMEA to outpatient and emergency management of sudden incidents helps optimize the emergency response process,thus enhancing the emergency response capability of general hospitals and ensuring effective handling of such incidents.

Objective:It aims to evaluate the impact of National Pharmaceutical Centralized Purchase(NPCP)and continuation policies on drug utilization,pricing,and expenditure,providing insights for optimizing national procurement strategies.Methods:Using descriptive statistics,a statistical analysis was conducted to examine changes in drug procurement amounts,Defined Daily Doses(DDDs),Defined Daily Dose cost(DDDc),and generic drug substitution rates pre-and post-implementation of the NPCP and continuation policies in hospitals and pharmacies across four municipalities.Results:The policy successfully achieved its goals of streamlining procurement processes,reducing drug prices,and promoting generic drug substitution.However,a notable trend of originator drug diversion to the retail sector was observed,indicating lingering patient reservations towards generics.Conclusion:It is needed to clarty the relation ship between NPCP continous policy and the medical insurance payment standard decision,strengthen the real-world evaluation on selected drug efficacy and safety,enhance the publicity on rated generic drugs,and promote the acceptance of public awareness.
