Objective:To explore the impact mechanism of strategic human resource management (SHRM) capabilities in hospital clinical departments on departmental organizational performance, providing references for improving the overall performance of hospitals.Methods:The research subjects were 46 clinical departments of a tertiary public hospital in Beijing. Using a stratified sampling method, at least one middle-level manager was selected from each department, and 30% of the medical staff were randomly sampled from each professional title level within the department. A self-made questionnaire was used to investigate the SHRM capabilities of each department from September to December 2023. The organizational performance of clinical departments was assessed using the departmental performance evaluation system established by the hospital. First, the performance target values for each department in 2023 were set based on the historical data from 2020 to 2022. Then, the actual performance evaluation data of 2023 were compared with the target values to calculate the achievement rate or deviation. Finally, the comprehensive performance scores of each department were calculated by weighting. The performance scores of the departments in 2023 were used as the outcome variable, while SHRM capabilities, department size, number of beds, and whether the department was a key department were used as antecedent condition variables. Fuzzy-set qualitative comparative analysis (fsQCA) was employed to explore the combinations of antecedent conditions that lead to high and low organizational performance in clinical departments.Results:A total of 1 391 valid questionnaires were collected. The weighted average score of SHRM capabilities in clinical departments was (4.23±0.27) points, and the total score of organizational performance evaluation in 2023 was 70.75 (52.50, 79.47) points. The consistency of each antecedent condition variable did not reach the critical value of 0.90, indicating that none of them were sufficient to be a necessary condition for high or low organizational performance in the departments. Two pathways to high organizational performance and two pathways to low organizational performance were identified. The solution consistency for the high organizational performance pathway was 0.83, with a coverage of 0.35, and both core conditions, acquisition capability and maintenance capability, were present. The solution consistency for the low organizational performance pathway was 0.85, with a coverage of 0.08, and the core conditions, development capability, was absent.Conclusions:Different combinations of antecedent condition variables, including the strategic human resource management capability of clinical departments, had varying impacts on the organizational performance of clinical departments. The possession of human resource acquisition, maintenance, and development capabilities by clinical departments was an essential condition for achieving high organizational performance. It is recommended to strengthen the construction of these three capabilities and emphasize the coordinated development of human resource management capabilities to enhance the organizational performance of clinical departments.

Mechanical thrombectomy has established efficacy in treating acute ischemic stroke caused by large vessel occlusion.However,for acute ischemic stroke associated with distal medium vessel occlusion(MeVO),endovascular recanalization remains challenging due to small vessel diameter,tortuous anatomy,and limited distal perfusion territory.As there is insufficient evidence to support application of mechanical thrombectomy for distal MeVO,it is not currently established as a standard indication for endovascular therapy.With advancements in the miniaturization and navigability of interventional devices,distal MeVO is gradually emerging as a potential target for mechanical thrombectomy.Nevertheless,occlusion of perforating arteries remains unsuitable for this technique due to their excessively small vessel caliber.This article reviewed the anatomical features and classification,imaging diagnosis,relevant clinical research,and novel materials and technologies pertaining to distal MeVO,aiming to provide reference for recanalization strategies in patients with this condition.

Objective To explore the role and potential mechanisms of plasma-activated solution(PAS)in alleviating dextran sulfate sodium salt(DSS)-induced ulcerative colitis.Methods We constructed a DSS-induced ulcerative colitis mouse model and evaluated the effect of PAS in vivo by observing mouse weight,calculating disease activity indexes,detecting inflammatory factors and oxidative stress indicators through ELISA.We also evaluated the effect of PAS on colon cell proliferation and migration ability through clone formation experiments,scratch experiments,and used Western blotting to determine the expression levels of proliferation-related proteins.Results PAS significantly reversed DSS-induced weight loss and increased disease activity indexes in mice(P＜0.05).The serum inflammatory cytokine levels(TNF-α,IL-6 and IL-1β)in PAS group were significantly reduced compared to those in DSS group(P＜0.05).PAS treatment could improve the imbalance of colonic redox homeostasis including changes of malondialdehyde,catalase and superoxide dismutase caused by DSS(P＜0.05).After the use of endothelial nitric oxide synthase inhibitors,changes in various indicators caused by in vivo PAS disappeared(P＜0.001).The clone formation ability of colon cells was stronger in the group treated with PAS,and the expression of proliferation-related proteins increased.Cell scratch experiments suggested that intervention with PAS could reverse the decrease in cell migration ability caused by lipopolysaccharide(P＜0.001).After the application of endothelial nitric oxide synthase inhibitors,the pro-proliferative and migratory effects of PAS disappeared(P＜0.05).Conclusion PAS alleviate DSS-induced colitis in mice and promote colonic epithelial cell repair through the eNOS pathway.

Objective To explore the application of plasma-activated solution(PAS)in the treatment of peritoneal metastasis in mice.Methods A mice model of peritoneal tumor transplantation was established,and PAS was prepared for intervention in the mice.The growth of the peritoneally transplanted tumor was assessed using in vivo imaging technology,while the apoptosis level was evaluated through flow cytometry,immunofluorescence,and Western blotting.Results At the in vitro level,there was no significant impact on tumor cell apoptosis level under adherent conditions observed when utilizing PAS(P＞0.05).Under non-adherent condition,PAS significantly augmented tumor cell apoptosis level(P＜0.05),substantially increased the proportion of deceased cells(P＜0.05),and markedly elevated intracellular total and mitochondrial reactive oxygen species levels(P＜0.05).In vivo level,using PAS following peritoneal transplanted tumor formation exhibited no noteworthy influence on peritoneal transplanted tumor growth(P＞0.05),while immediate utilization of PAS during model conducting effectively reduced abdominal tumor spread(P＜0.05).Conclusion PAS inhibits tumor peritoneal dissemination in mice by promoting tumor cell anoikis.

Objective This study aimed to investigate the antimicrobial resistance profiles of bacterial strains isolated from pediatric intensive care units(PICU)in China for better antimicrobial therapy.Methods Clinical isolates were collected from 17 institutions,including tertiary care children's hospitals and pediatric department of tertiary general hospitals in China from January 1,2020 to December 31,2022.Antimicrobial susceptibility testing was carried out according to a unified protocol using Kirby-Bauer method or automated systems.Results were interpreted according to the breakpoints released by the Clinical and Laboratory Standards Institute(CLSI)in 2020.Results A total of 10 688 isolates were collected,including gram-positive organisms(39.2％)and gram-negative organisms(60.8％).The top three organisms were S.aureus(13.6％,1 453/10 688),A.baumannii(10.0％,1 067/10 688),and coagulase-negative Staphylococcus(9.9％,1 058/10 688).Multi-drug resistant organisms(MDROs)were very common in children.The prevalence of methicillin-resistant Staphylococcus aureus(MRSA),carbapenem-resistant Enterobacterales(CRE),carbapenem-resistant E.coli,carbapenem-resistant K.pneumoniae(CRKP),carbapenem-resistant A.baumannii(CRAB),and carbapenem-resistant P.aeruginosa(CRPA)was 41.1％,19.4％,8.8％,30.9％,67.4％,and 28.8％,respectively.Overall,more than 50％of Enterobacteriales isolates were resistant to cephalosporins,while nearly 25％of Enterobacteriales isolates were resistant to carbapenems.MDROs were highly resistant to commonly used antibiotics.More than 80％of CRE and CRAB strains were resistant to all beta-lactam antibiotics.CRE and CRAB showed low resistance rates to tigecycline and polymyxin.CRPA showed lower resistance rates to piperacillin,beta-lactamase inhibitor combinations than the resistance rates to third and fourth generation cephalosporins.All of the Staphylococcus and Enterococcus isolates were susceptible to vancomycin and tigecycline.None of PRSP strains isolated from meningitis and nonmeningitis samples were resistant to rifampicin,vancomycin,or linezolid.The prevalence of β-lactamase-negative ampicillin-resistant(BLNAR)strains was 43.3％in Haemophilus influenzae.Conclusions MDROs were prevalent in PICU.It is necessary to establish an effective multidisciplinary team(MDT)to control the antimicrobial resistance.

Objective:To investigate the effect of repetitive transcranial magnetic stimulation(rTMS)on sleep structure and quality in children with autism spectrum disorder(ASD).Methods:Sixty children with ASD who met the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)criteria were randomly assigned to rTMS treatment group and pseudo-treatment group.The rTMS group received bilateral low-frequency(0.5 Hz)stimulation,and the pseudo-treatment group received pseudo-stimulation at the same time and place.Sleep quality and autism symptoms were assessed at baseline,midpoint(15 sessions),and endpoint(30 sessions),using the Childhood Sleep Disorders Scale(SDSC)and the Behavior Rating Scale for Children with Autism Spectrum Disorders(ABC)before treatment,15 times and 30 times of intervention,and statistical analysis was performed.Results:There was no significant difference in SDSC factor and total score between the two groups before treatment(P＞0.05).After 15 and 30 treatments,the total scores of SDSC and all factors were lower in the rTMS group than in the pseudo-treatment group(P＜0.05).Repeated measurement ANOVA found that there was an interaction be-tween the groups and the number of interventions,that is,the scores of the two groups had different downward trends,and the decline of the treatment group was more obvious than that of the pseudo-treatment group.There was no significant difference in the interaction between ABC scale scores and intervention times(P＞0.05).Conclu-sion:Repetitive transcranial magnetic stimulation significantly improves the sleep structure and quality in children with autism spectrum disorder.

Objective To examine the expression levels of inflammatory factors,including IL-6,IL-10,MMP-9,IL-17A,and LDH,in the cerebrospinal fluid(CSF)of patients with spontaneous intracerebral hemor-rhage(sICH),and to investigate their associations with disease severity and clinical outcomes.Methods A total of 168 patients with sICH admitted to Tangshan GongRen Hospital between January 2023 and January 2025 were prospectively enrolled as the study group,while 30 non-sICH patients who underwent lumbar puncture during the same period served as the control group.Levels of inflammatory factors in CSF were compared between the two groups.Spearman's rank correlation analysis was performed to assess the association between inflammatory factor levels and clinical severity in sICH patients.Binary logistic regression analysis was conducted to identify independent predictors of sICH prognosis.Receiver operating characteristic(ROC)curve analysis was employed to evaluate the prognostic value of these inflammatory factors in sICH.Results The levels of IL-6,IL-10,MMP-9,IL-17A,and LDH in the CSF of patients with sICH were significantly higher than those in non-sICH patients(all P<0.05).Furthermore,among sICH patients,these biomarker levels exhibited a graded increase according to disease severity:severe>moderate>mild(all P<0.05).Spearman correlation analysis revealed significant positive correlations between CSF levels of IL-6,IL-10,MMP-9,IL-17A,and LDH and the NIHSS scores,with correlation coefficients(r)of 0.686,0.553,0.685,0.593,and 0.695,respectively(all P<0.05).When comparing the prognoses of sICH patients,hematoma size,NIHSS score,and CSF levels of IL-6,IL-10,MMP-9,IL-17A,and LDH were significantly higher in the deceased group than in the survival group(P<0.05),whereas ApoA1 levels were lower in the deceased group(P<0.05).Logistic regression analysis revealed that hematoma size,NIHSS score,and elevated CSF levels of IL-6,IL-10,MMP-9,IL-17A,and LDH were independent risk factors for mortality in sICH patients(P<0.05).ROC curve analysis showed that the AUC values for CSF IL-6,IL-10,MMP-9,IL-17A,and LDH in predicting sICH prognosis were 0.794,0.754,0.670,0.717,and 0.683,respectively.Notably,the combination of CSF inflammatory markers with hematoma size and NIHSS score yielded an AUC of 0.993,demonstrating significantly greater predictive accuracy than CSF inflammatory markers alone(P<0.05).Conclusions The levels of inflammatory factors in the CSF,including IL-6,IL-10,MMP-9,IL-17A,and LDH,were elevated in patients with sICH and positively correlated with disease severity.Combining CSF inflammatory markers with the NIHSS score and hematoma size improved the predictive accuracy for sICH prognosis.
