Methods: The hospital initiated an emergency plan involving multi-departmental defense and control. It adopted a series of nosocomial infection prevention and control measures, including strengthening pre-examination and triage, optimizing the consultation process, improving the hospital’s architectural composition, implementing graded risk management, enhancing personal protection, and implementing staff training and supervision. Descriptive research was used to evaluate the short-term effects of these in-hospital prevention and control strategies. The analysis compared changes in related evaluation indicators between January 24, 2020 and February 12, 2020 (Chinese Lunar New Year’s Eve 2020 to lunar January 19) and the corresponding lunar period of the previous year. Results: Compared to the same period last year, the outpatient fever rate increased by 1.85-fold (P P Conclusion: The nosocomial infection prevention and control strategies implemented during this specific period improved the detection and control abilities for the COVID-19 source of infection and enhanced the compliance with measures. This likely contributed significantly to avoiding the occurrence of nosocomial infection.展开更多

文摘Objective:To investigate the lifestyle and myopia among primary school students in urban areas of Fujian with the context of myopia prevention and control measures,aiming to provide scientific evidence for identifying high-risk myopia population and formulating effective intervention strategies.Methods:A cross-sectional study was conducted from October to November 2023,enrolling 811 fourth-grade students from three primary schools in three cities across Fujian.Personal information and lifestyle-related pattern were collected using customized questionnaire.Participants underwent comprehensive ophthalmic assessments including distance visual acuity tests and refractive examinations.Logistic regression analysis was used to assess the impact of lifestyle on the onset of myopia.Results:The prevalence of myopia among fourth-grade students in urban primary schools in Fujian was 46.4%.Only 25.8%students engaged in outdoor activities for more than 2 hours daily,while63.3%participated in outdoor activities during class breaks.Multivariate Logistic regression analysis revealed that outdoor activities during class breaks(OR=0.646(95%confidence interval(CI):0.473-0.881),P=0.006)and daily time spent outdoors(2-3 hours,OR=0.682(95%CI:0.466-0.993),P=0.047;more than 3 hours,OR=0.403(95%CI:0.192-0.796),P=0.01)were independent protective factors against myopia.Lifestyle significantly enhanced the predictive performance for myopia(P=0.01).Additionally,parental myopia(one parent with myopia,OR=2.247(95%CI:1.612-3.145),P<0.001;both parents with myopia,OR=4.824(95%CI:3.262-7.204),P<0.001)emerged as a key risk factor for myopia.Conclusions:There is considerable scope for improving the lifestyle of primary school students in urban areas of Fujian.Lifestyle is strongly associated with myopia onset,highlighting the need for schools and families to actively encourage students to engage in more outdoor activities and take breaks outdoors to prevent and control myopia.Students with parents,especially both parents,having myopia should be considered as a key target group for myopia prevention efforts.

文摘Objective Alzheimer’s disease(AD)presents a significant global health challenge with a steadily increasing prevalence and impact.This comprehensive review aimed to delve into the epidemiology,pathophysiology,pharmacological therapies,emerging research,challenges,and future directions of AD.Major findings from recent studies were synthesised,encompassing insights into the global prevalence,molecular pathology,high-risk factors,and therapeutic interventions,including cholinesterase inhibitors,glutamate receptor antagonists,and antibodies against Aβand tau proteins.Additionally,emerging research areas such as gene therapy and lipid nanoparticles were highlighted.This review emphasised the urgent need for ongoing research on novel therapeutic avenues and addressing the challenges in AD diagnosis,treatment,and care.Future perspectives underscore the potential of disease-modifying treatments,personalised medical approaches,and holistic interventions to alleviate the growing burden of AD on individuals,families,and healthcare systems worldwide.By fostering collaboration and innovation,we can strive towards a future where effective prevention,early detection,and personalised treatments enhance the lives of millions affected by AD globally.
文摘Objective: To evaluate the role of prevention and control strategies for nosocomial infection in a tertiary teaching hospital during the sudden outbreak of Corona Virus Disease 2019 (COVID-19). Methods: The hospital initiated an emergency plan involving multi-departmental defense and control. It adopted a series of nosocomial infection prevention and control measures, including strengthening pre-examination and triage, optimizing the consultation process, improving the hospital’s architectural composition, implementing graded risk management, enhancing personal protection, and implementing staff training and supervision. Descriptive research was used to evaluate the short-term effects of these in-hospital prevention and control strategies. The analysis compared changes in related evaluation indicators between January 24, 2020 and February 12, 2020 (Chinese Lunar New Year’s Eve 2020 to lunar January 19) and the corresponding lunar period of the previous year. Results: Compared to the same period last year, the outpatient fever rate increased by 1.85-fold (P P Conclusion: The nosocomial infection prevention and control strategies implemented during this specific period improved the detection and control abilities for the COVID-19 source of infection and enhanced the compliance with measures. This likely contributed significantly to avoiding the occurrence of nosocomial infection.
文摘The problem of gastric cancer(GC)prevention remains relevant for a long time.Various methods of population serological screening of atrophic gastritis and precancerous changes in the gastric mucosa have been created at present.Modern endoscopic and morphological methods of verification of the diagnosis of precancerous diseases and changes in the gastric mucosa have been introduced into the practice of gastroenterologists and oncologists.GC risk stratification systems allow the formation of risk groups that require population screening.Practical hints for population serological screening of atrophic gastritis,endoscopic and morphological verification of precancerous changes and diseases of the stomach recommend using it:When developing state programs for the prevention of stomach cancer;when implementing preventive measures for stomach cancer by doctors of all specialties;the authors also offer the possibility of use by anyone over the age of 40,provided that they seek methodological help from their doctor;in the work of health schools in any medical and preventive institutions.The use of an assessment system of certain risk factor signatures with prognostic value would add significant assistance to preventive measures against GC.

文摘Aiming at reducing the dust pollution during the tunneling process and improving the application efficiency of air curtain dust prevention technology,according to the changes of radial jet velocity(v_(r)),axial extraction velocity(v_(e))and extraction distance(L)in the formation process of air curtain,the numerical simulation method was used to analyze the rules of airflow structure evolution and the diffusion characteristics of dust particles in fully mechanized excavation tunnel.The results indicate that as v_(r) and v_(e) increase,the migration path of the wall jet of the air curtain changes into an axial direction;as L decreases,the migration distance increases accordingly.These phenomena make the airflow distribution in the working face tends to be uniform.The dust diffusion distance reduces as well,wherein,the range of the discrete area of dust particles decreases sharply,until all dust particles are concentrated in the accumulation area.On this basis,the v_(r),v_(e) and L were optimized and applied in the 63_(up) 08 fully mechanized working face.By the application of the optimal parameters,the average dust removal efficiency at the driver’s position increased by 71%.The dust concentration was reduced and the working environment had been improved effectively.
