Creutzfeldt-Jakob disease(CJD)is a rapidly progressive and fatal neurodegenerative disorder caused by prions,with certain infectivity and iatrogenic transmission risks.With the rapid progress and application of new dia-gnostic biomarkers and detection methods,as well as the construction and improvement of surveillance and reporting systems,the detection of CJD in patients domestically and internationally has shown an increasing trend year by year.Due to its long incubation period and heterogeneity of early symptoms,early identification and diagnosis of the disease is difficult,increasing the risk of transmission within medical institutions.Currently,there is a lack of con-sensus on the infection prevention and control of CJD.In order to timely identify and diagnose CJD as well as effec-tively block its transmission in medical institutions,this consensus summarizes 15 clinical concerns and formulates 24 specific recommendations based on the latest domestic and international research findings and clinical evidence,as well as combines with clinical practice,aiming to standardize healthcare-associated infection prevention and control measures for CJD and reduce its transmission risk in medical institutions.

OBJECTIVE To explore the construction path and effectiveness of dynamic zoning management model during dengue fever pandemic,and to provide evidence for optimizing hospital-acquired infection control strategies.METHODS Retrospective analysis method was conducted,the practical data of dengue fever epidemic prevention and control in a tertiary general hospital in 2024 as the sample,to evaluate the application effect of the"zoned treatment-dynamic allocation-environmental coordination"trinity prevention and control model.Based on the optimized infection prevention and control strategies implemented during the epidemic,such as the"core ward-specialist collaboration"dynamic zoning,flexible ward expansion,hierarchical disinfection,real-time dynamic re-source allocation mechanism,and precise environmental intervention,a comprehensive evaluation of prevention and control efficiency was conducted across key dimensions including infection control,resource utilization,pre-vention and control costs and patient outcomes.RESULTS Through the construction of flexible wards,the number of expanded isolation beds accounted for 44.13％(331/750)of the total beds,including 144 beds(19.20％)in core wards and 187 beds(24.93％)in specialist collaborative wards.The expansion of specialist collaborative wards increased the isolation admission capacity by 129.86％.The two types of wards admitted 57.27％of single-disease dengue patients and 42.73％of isolated patients with combined diagnosis and treatment needs from inter-nal medicine,surgery,obstetrics,gynecology,and pediatrics.The minimum ratio of flexible buffer isolation beds was 6.34％(21/331),with a maximum daily treatment capacity of 310 patients.Data showed:hospital infec-tion incidence rate was 0,peak adult mosquito density was 0.13 mosquitoes/trap·night,prevention and control cost was 95.22 yuan per case,and patient satisfaction increased by 1.98％(95.09 vs.93.24,P=0.014).CONCLUSIONS The"dynamic zoning"model achieves rapid spatial elastic reconstruction of inpatient wards for"peace-epidemic conversion"through the coordination of three links.Based on effectively blocking in-hospital transmission,it ensures the needs of multi-specialty treatment,enabling the hospital to strike a balance between the bottom line of prevention and control safety and the fulfillment of diversified medical service requirements dur-ing the epidemic outbreak period.It can provide standardized prevention and control solutions for medical institu-tions to respond to public health emergencies of vector-borne infectious diseases,and achieve the goal of zero cross infection of hospital-acquired Dengue.

In order to improve the operation difficulties in the narrow space of the nasal maxillary sinus, the nasal continuum minimally invasive surgical robot system is designed. The ball-and-socket joints and NiTiNol tubes are used as the main body of the continuum structure to improve the degree of freedom. The hardware systems and software systems are designed. The security control policies are planned. Finally, the robot confirmed prototype experiments are conducted and the feasibility of continuum robot confirmed through master-slave control experiment and animal experiment.
