Objective: To explore the application effectiveness of healthcare failure mode and effect analysis (HFMEA) in optimizing intelligent blood logistics transport pathways for safety assurance. Methods: Data from 1 851 cases of intelligent blood logistics transport were collected between September 2023 and March 2025. Based on the implementation phases of HFMEA measures, the cases were divided into a control group (n=120), observation group 1 (n=219), and observation group 2 (n=1 512). Through systematic analysis of the transport processes, hazard scoring and decision tree analysis were conducted for each process, and phased optimization measures were implemented for high-risk failure modes. Results: The transport duration of intelligent blood logistics was 35.5 (20.8, 71.1) min in the control group, 25.1 (10.9, 40.7) min in observation group 1, and 9.9 (4.2, 44.5) min in observation group 2. Observation group 2 exhibited significantly shorter transport time compared to both observation group 1 and the control group, with statistically significant differences between groups (P<0.000 1). Conclusion: The implementation of HFMEA-driven measures significantly reduced intelligent blood logistics transport duration, thereby fostering the evolution of smart hospital ecosystems while enhancing healthcare service quality and operational efficiency.

Objective To examine the changing prevalence and antimicrobial resistance profiles of Burkholderia cepacia in 52 hospitals across China from 2015 to 2021.Methods A total of 9 261 strains of B.cepacia were collected from 52 hospitals between January 1,2015 and December 31,2021.Antimicrobial susceptibility of the strains was tested using Kirby-Bauer method or automated antimicrobial susceptibility testing systems according to a unified protocol.The results were interpreted according to the breakpoints released in the Clinical & Laboratory Standards Institute(CLSI)guidelines(2023 edition).Results A total of 9 261 strains of B.cepacia were isolated from all age groups,especially elderly patients.The proportion was 11.1％(1 032 strains)in children,significantly lower than the proportion in adults.About half(46.5％,4 310/9 261)of the strains were isolated from patients at least 60 years old and 42.3％(3 919/9 261)of the strains were isolated from young adults.Most isolates(71.1％)were isolated from sputum and respiratory secretions,followed by urine(10.7％)and blood samples(8.1％).B.cepacia isolates were highly susceptible to the five antimicrobial agents recommended in the CLSI M100 document(33rd edition,2023).B.cepacia isolates showed relatively higher resistance rates to meropenem and levofloxacin.However,the resistance rates to ceftazidime,trimethoprim-sulfamethoxazole,and minocycline remained below 8.1％.The percentage of B.cepacia strains resistant to levofloxacin was the highest compared to other antibiotics in any of the three age groups(from 12.4％in the patients＜18 years old to 20.6％in the patients aged 60 years or older).Conclusions B.cepacia is one of the clinically important non-fermenting gram-negative bacteria.Accurate and timely reporting of antimicrobial susceptibility test results and ongoing antimicrobial resistance surveillance are helpful for rational prescription of antimicrobial agents and proper prevention and control of nosocomial infections.

Objective To summarize the changing prevalence of carbapenem resistance in Enterobacterales based on the data of CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021 for improving antimicrobial treatment in clinical practice.Methods Antimicrobial susceptibility testing was performed using a commercial automated susceptibility testing system according to the unified CHINET protocol.The results were interpreted according to the breakpoints of the Clinical & Laboratory Standards Institute(CLSI)M100 31st ed in 2021.Results Over the seven-year period(2015-2021),the overall prevalence of carbapenem-resistant Enterobacterales(CRE)was 9.43％(62 342/661 235).The prevalence of CRE strains in Klebsiella pneumoniae,Citrobacter freundii,and Enterobacter cloacae was 22.38％,9.73％,and 8.47％,respectively.The prevalence of CRE strains in Escherichia coli was 1.99％.A few CRE strains were also identified in Salmonella and Shigella.The CRE strains were mainly isolated from respiratory specimens(44.23±2.80)％,followed by blood(20.88±3.40)％and urine(18.40±3.45)％.Intensive care units(ICUs)were the major source of the CRE strains(27.43±5.20)％.CRE strains were resistant to all the β-lactam antibiotics tested and most non-β-lactam antimicrobial agents.The CRE strains were relatively susceptible to tigecycline and polymyxins with low resistance rates.Conclusions The prevalence of CRE strains was increasing from 2015 to 2021.CRE strains were highly resistant to most of the antibacterial drugs used in clinical practice.Clinicians should prescribe antimicrobial agents rationally.Hospitals should strengthen antibiotic stewardship in key clinical settings such as ICUs,and take effective infection control measures to curb CRE outbreak and epidemic in hospitals.

Objective To characterize the changing species distribution and antibiotic resistance profiles of respiratory isolates in hospitals participating in the CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021.Methods Commercial automated antimicrobial susceptibility testing systems and disk diffusion method were used to test the susceptibility of respiratory bacterial isolates to antimicrobial agents following the standardized technical protocol established by the CHINET program.Results A total of 589 746 respiratory isolates were collected from 2015 to 2021.Overall,82.6％of the isolates were Gram-negative bacteria and 17.4％were Gram-positive bacteria.The bacterial isolates from outpatients and inpatients accounted for(6.0±0.9)％and(94.0±0.1)％,respectively.The top microorganisms were Klebsiella spp.,Acinetobacter spp.,Pseudomonas aeruginosa,Staphylococcus aureus,Haemophilus spp.,Stenotrophomonas maltophilia,Escherichia coli,and Streptococcus pneumoniae.Each microorganism was isolated from significantly more males than from females(P＜0.05).The overall prevalence of methicillin-resistant S.aureus(MRSA)was 39.9％.The prevalence of penicillin-resistant S.pneumoniae was 1.4％.The prevalence of extended-spectrum β-lactamase(ESBL)-producing E.coli and K.pneumoniae was 67.8％and 41.3％,respectively.The overall prevalence of carbapenem-resistant E.coli,K.pneumoniae,Enterobacter cloacae,Pseudomonas aeruginosa,and Acinetobacter baumannii was 3.7％,20.8％,9.4％,29.8％,and 73.3％,respectively.The prevalence of β-lactamase was 96.1％in Moraxella catarrhalis and 60.0％in Haemophilus influenzae.The H.influenzae isolates from children(＜18 years)showed significantly higher resistance rates to β-lactam antibiotics than the isolates from adults(P＜0.05).Conclusions Gram-negative bacteria are still predominant in respiratory isolates associated with serious antibiotic resistance.Antimicrobial resistance surveillance should be strengthened in clinical practice to support accurate etiological diagnosis and appropriate antimicrobial therapy based on antimicrobial susceptibility testing results.

ObjectiveTo improve the accuracy of discrete element method in simulating the processing of traditional Chinese medicine（TCM） powder system under low shear conditions. MethodsIn this study， extract powders of Tongsaimai tablets and Qige granules were used as the research objects， the angle of repose（AOR） and effective angle of internal friction of the two materials were determined by AOR test method and shear cell test method. Based on the Hertz-Mindlin with JKR V2 contact model and particle scaling theory， taking the particle-particle restitution coefficient（A）， particle-particle static friction coefficient（B）， particle-particle rolling friction coefficient（C）， particle-steel restitution coefficient（D）， particle-steel static friction coefficient（E）， particle-steel rolling friction coefficient（F） and Johnson-Kendall-Roberts（JKR） surface energy（G） as test factors， the simulated contact parameters of Tongsaimai tablets extract powder were first calibrated with a single reference value using AOR as the reference value， and then the simulated contact parameters of Tongsaimai tablets extract powder as well as Qige granules extract powder were co-calibrated with AOR and effective angle of internal friction as the joint reference value， respectively. Then， Plackett-Burman design was used to screen the critical contact parameters that have a significant effect on the simulated reference value， and the steepest ascent design was used to determine the optimal range of the critical contact parameters， finally， the regression model between the critical contact parameters and the simulated reference values was established through the design of the response surface test， and the critical contact parameters were calibrated based on the regression model and the desirability function approach. ResultsThe optimal combination of discrete elemental contact parameters A-G for Tongsaimai tablets extract powder under a single reference value was 0.100， 0.718， 0.616， 0.100， 0.400， 0.250 and 0.075 J·m^-2， which was validated to have relative errors of 0.10% and -8.64% for the simulated AOR and the simulated effective angle of internal friction， respectively. And the optimal combination of discrete elemental contact parameters A-G for Tongsaimai tablets extract powder at the joint reference values was 0.100， 0.682， 0.598， 0.100， 0.521， 0.294 and 0.075 J·m^-2， which was verified to have relative errors of 0.10% and -0.18% for the simulated AOR and the simulated effective angle of internal friction， respectively. The optimal combination of discrete elemental contact parameters A-G for Qige granules extract powder at the joint reference values was 0.150， 0.370， 0.330， 0.150， 0.500， 0.500 and 0.100 J·m^-2， which was verified to have relative errors of 2.70% and -1.30% for the simulated AOR and the simulated effective angle of internal friction， respectively. Compared with the single reference value method， the joint calibration method not only increased the number of the critical contact parameters for characterizing particle-device interactions， but also was more accurate and reliable. ConclusionCompared with the results of single reference value calibration， the results obtained by the method of joint calibration of discrete element simulation contact parameters with AOR and effective angle of internal friction as the reference values are more accurate， which can provide more accurate and reliable simulation physical property data for the simulation experiments of TCM extract powder under low shear process conditions.

Objective:To explore the ideological and political education elements and methods in the introduction to nursing course, so as to enhance its ideological educational effectiveness. Methods:In February 2024, based on a "three-stage" teaching model (pre-class, in-class, and post-class), this study reformed the ideological and political education plan for the introduction to nursing course by integrating online and offline case studies and resources, expanding educational materials, and organizing teaching assessments and effectiveness surveys. A semester-long ideological and political education practice was implemented for 237 first-year nursing students from four classes in Medical College of Xinjiang University of Science and Technology. The effectiveness was evaluated by exam scores and a self-designed Introduction to Nursing Teaching Effectiveness Evaluation Scale under the ideological and political education framework. Results:Among the 237 students, there were 107 males and 130 females, aged (18.50 ± 1.12) years old, 63 achieved a passing grade, 149 achieved a good grade, and 18 achieved an excellent grade, with a pass rate of 97.05% (230/237). The scores of the six dimensions of interest stimulation in teaching methods, acceptance of teaching methods, knowledge review and application, knowledge comprehension and retention, self-challenge and improvement, and satisfaction with learning outcomes within 1 week after the end of the course scores were (3.92 ± 1.11), (4.21 ± 0.82), (4.05 ± 0.97), (4.05 ± 0.89), (4.11 ± 0.94), (4.03 ± 0.90) points, which were significantly higher than 1 week before the start of the course (3.43 ± 1.00), (3.54 ± 1.03), (3.48 ± 1.08), (3.47 ± 1.04), (3.52 ± 1.05), (3.47 ± 1.01) points. The differences were statistically significant ( t values were -19.38- -13.22, all P < 0.01). Conclusions:The "three-stage" teaching model in the introduction to nursing course effectively integrates professional education with ideological and political education, improves students′ academic performance, enhances learning effectiveness in nursing practice, and strengthens the overall impact of ideological and political education.

Purpose To explore the diagnostic value of two-dimensional speckle tracking echocardiography(2D-STE)in differentiating left ventricular hypertrophy(LVH)caused by Fabry disease from other etiologies.Materials and Methods A total of 23 patients clinically confirmed Fabry disease with LVH(Fabry disease group)in Peking University First Hospital from August 2014 to February 2023,retrospectively.23 patients with hypertensive LVH(hypertensive LVH group)and 23 with hypertrophic cardiomyopathy(HCM)(HCM group)were also included.Conventional echocardiographic parameters and 2D-STE-derived left atrial strain and left ventricular longitudinal strain were analyzed and compared among the three groups.LASSO regression was used to select variables and construct a diagnostic model to differentiate hypertensive LVH,HCM and Fabry disease group.Results The Fabry disease group showed significantly reduced left ventricular global longitudinal strain and segmental left ventricular longitudinal strain in the basal anterior wall,basal anterolateral wall and mid inferior wall compared to the hypertensive LVH group(P<0.05).There were no significant differences in left atrial strain,left ventricular global longitudinal strain and segmental left ventricular longitudinal strain between the Fabry disease and HCM groups(P>0.05).Compared to the conventional echocardiography-based model,the combined model did not significantly improve diagnostic accuracy for differentiating the three etiologies(Z=-1.314--0.594,all P>0.05).Conclusion Compared to patients with hypertensive LVH,HCM and Fabry disease group exhibit varying degrees of decrease in global and segmental longitudinal strain of the left atrium and left ventricle.Additional measurements of left ventricular longitudinal strain and left atrial strain do not provide significant incremental diagnostic value over conventional echocardiography in distinguishing among Fabry disease,hypertensive LVH and HCM.
