Objective:To construct a preventive maintenance path based on risk control model for medical equipment in the operating room,and analyze its application effect in the management for medical equipment in the operating room.Methods:Based on 7 key factors included equipment characteristics,usage duration,startup frequency,operating efficiency,operator skills,maintenance frequency,and technical support in risk control model,we followed management mode of preventive maintenance,and constructed a preventive maintenance path from six dimensions which included management of equipment application,preventive maintenance and upkeep,predictive maintenance,fault repair,post upkeep,and quality monitoring.A total of 215 used medical equipment in operating room at Xiaolan People's Hospital of ZhongShan from January 2022 to December 2022 were selected,and the equipment during January and December 2022 received maintenance management by using conventional management method,and these during January and December 2023 received maintenance management by using preventive maintenance path method based on risk control model for medical equipment(model management method).The quality of management and operation for equipment between two kinds of management methods were compared.A self-designed questionnaire was adopted to investigate the operators'satisfaction for service quality of equipment in operating rooms.Results:The average standardization degree of using equipment,efficiency of maintenance,timely maintenance,and qualification rate of quality inspection of adopting model management method were respectively(94.43±4.26)%,(97.74±1.53)%,(86.78±6.72)%and(96.48±3.02)%,all of which were higher than those of adopting conventional method(t=22.583,34.738,14.820,18.577,P<0.05).The average rate of starting equipment and self-repair rate of the model management method were significantly higher than those of the conventional method,and the differences were statistically significant(t=10.355,7.624,12.811,P<0.05).The satisfaction scores of operators who used management for adopting model management method were higher than those for adopting conventional management method in applying and managing equipment,preventive upkeep,predictive maintenance,fault repair,post upkeep and quality monitoring,and the differences were statistically significant(t=18.653,22.942,18.752,23.673,40.055,37.120,P<0.05).Conclusion:The preventive maintenance path based on risk control model for medical equipment in operating room can improve the management quality for equipment in operating room,and enhance management effectiveness and operators'satisfaction.

Objective To investigate the anti-inflammatory protective effects of remimazolam on microglial cells and elucidates the potential molecular mechanisms underlying these effects. Methods The mouse microglial cell line (BV2) was selected as the research object. The following groups were set up:the control group (complete medium),the Rema group (200 μg/mL remimazolam),the model group (1 μg/mL lipopolysaccharide,LPS),and different-concentration administration groups (1 μg/mL LPS+50,100,200 μg/mL remimazolam). In the Rema group,cells were treated with 200 μg/mL remimazolam alone for 26 h. In the model group,cells were treated with LPS for 24 h. In the different-concentration administration groups,cells were pre-treated with different concentrations of remimazolam for 2 h,and then treated with LPS for 24 h. The effects of LPS and remimazolam on the morphology of BV2 cells were observed and evaluated using an optical microscope. Cell viability was determined using the CCK-8 assay,while the expression and secretion of inflammatory cytokines were quantified by quantitative real-time PCR and ELISA. Reactive oxygen species (ROS) levels were measured using a fluorescent probe. Additionally,malondial-dehyde (MDA) content,superoxide dismutase (SOD) activity,and glutathione peroxidase (GSH) activity were evaluated using respective assay kits. Western blot analysis was conducted to examine the protein expression levels of Bax,Bcl-2,IL-1β,RAGE,NF-κB,p-NF-κB,IκBα,p-IκBα,iNOS,and Arg-1. Immunofluorescence staining was employed to visualize NF-κB nuclear translocation and M1/M2 polarization in the cells. Results Compared to the control group,LPS-treated BV2 cells demonstrated significantly reduced cell viability,elevated expression and se-cretion of inflammatory cytokines (TNF-α,IL-6,IL-1β),decreased activities of SOD and GSH,and increased in-tracellular levels of MDA and ROS. Additionally,RAGE protein levels were upregulated,along with enhanced phos-phorylation of IκBα and NF-κB,leading to observable NF-κB nuclear translocation. The expression of the M1 marker iNOS was upregulated,while that of the M2 marker Arg-1 was downregulated. In contrast,in the LPS+Rema group,cell viability was restored,expression and secretion of inflammatory cytokines were attenuated,SOD and GSH activities were improved,and levels of MDA and ROS were reduced compared to the LPS group. Furthermore,RAGE protein expression and phosphorylation levels of IκBα and NF-κB were diminished,inhibiting NF-κB nuclear translocation. The expression of the M1 marker iNOS was downregulated,while that of the M2 marker Arg-1 was up-regulated. Conclusion Remimazolam mitigates LPS-induced inflammation by facilitating the transition of microglial cells from the M1 to the M2 phenotype via modulation of the NF-κB pathway and reduction of ROS production.

BACKGROUND: While emotional distress, encompassing anxiety and depression, has been associated with negative clinical outcomes, its impact across various clinical departments and general hospitals has been less explored. Previous studies with limited sample sizes have examined the effectiveness of specific treatments (e.g., antidepressants) rather than a systemic management strategy for outcome improvement in non-psychiatric inpatients. To enhance the understanding of the importance of addressing mental health care needs among non-psychiatric patients in general hospitals, this study retrospectively investigated the impacts of emotional distress and the effects of early detection and management of depression and anxiety on hospital length of stay (LOS) and rate of long LOS (LLOS, i.e., LOS >30 days) in a large sample of non-psychiatric inpatients. METHODS: This retrospective cohort study included 487,871 inpatients from 20 non-psychiatric departments of a general hospital. They were divided, according to whether they underwent a novel strategy to manage emotional distress which deployed the Huaxi Emotional Distress Index (HEI) for brief screening with grading psychological services (BS-GPS), into BS-GPS ( n = 178,883) and non-BS-GPS ( n = 308,988) cohorts. The LOS and rate of LLOS between the BS-GPS and non-BS-GPS cohorts and between subcohorts with and without clinically significant anxiety and/or depression (CSAD, i.e., HEI score ≥11 on admission to the hospital) in the BS-GPS cohort were compared using univariable analyses, multilevel analyses, and/or propensity score-matched analyses, respectively. RESULTS: The detection rate of CSAD in the BS-GPS cohort varied from 2.64% (95% confidence interval [CI]: 2.49%-2.81%) to 20.50% (95% CI: 19.43%-21.62%) across the 20 departments, with a average rate of 5.36%. Significant differences were observed in both the LOS and LLOS rates between the subcohorts with CSAD (12.7 days, 535/9590) and without CSAD (9.5 days, 3800/169,293) and between the BS-GPS (9.6 days, 4335/178,883) and non-BS-GPS (10.8 days, 11,483/308,988) cohorts. These differences remained significant after controlling for confounders using propensity score-matched comparisons. A multilevel analysis indicated that BS-GPS was negatively associated with both LOS and LLOS after controlling for sociodemographics and the departments of patient discharge and remained negatively associated with LLOS after controlling additionally for the year of patient discharge. CONCLUSION Emotional distress significantly prolonged the LOS and increased the LLOS of non-psychiatric inpatients across most departments and general hospitals. These impacts were moderated by the implementation of BS-GPS. Thus, BS-GPS has the potential as an effective, resource-saving strategy for enhancing mental health care and optimizing medical resources in general hospitals.

The correlation between hearing loss (HL) and physical performance in patients receiving maintenance hemodialysis (MHD) remains poorly investigated. This study explored the association between HL and physical performance in patients on MHD. Methods: This multicenter cross-sectional study was conducted between July 2020 and April 2021 in seven hemodialysis centers in Shanghai and Suzhou, China. The hearing assessment was performed using pure-tone average (PTA). Physical performance was assessed using the Timed Up and Go Test (TUGT), handgrip strength, and gait speed. Results: Finally, 838 adult patients (male, 516 [61.6%]; 61.2 ± 2.6 years) were enrolled. Among them, 423 (50.5%) had mild to profound HL (male, 48.6% and female, 53.4%). Patients with HL had poorer physical performance than patients without HL (p < 0.001). TUGT was positively correlated with PTA (r = 0.265, p < 0.001), while handgrip strength and gait speed were negatively correlated with PTA (r = –0.356, p < 0.001 and r = –0.342, p < 0.001, respectively). Physical performance in patients aged <60 years showed significant dose-response relationships with HL. After adjusting for confounders, the odds ratios (95% confidence intervals) for HL across the TUGT quartiles (lowest to highest) were 1.00 (reference), 1.15 (0.73–1.81), 1.69 (1.07–2.70), and 2.87 (1.69–4.88) (p for trend = 0.005). Conclusion: Lower prevalence of HL was associated with a faster TUGT and a stronger handgrip strength in patients on MHD.
