Objective Human facial morphology is an appearance phenotype with high heritability,high diversity,and complexity.Traditional facial morphological genetic analysis is mostly based on facial landmark measurements,using linear regression for genome-wide association studies,but this method extracts limited facial morphological feature information.This study established an extraction method for multidimensional facial representations and validated the correlation between 473 single-nucleotide polymorphisms(SNPs)previously reported to be significantly associated with facial features and facial representations in the Han Chinese population.Methods After acquiring facial 3D images,3D morphable face models and HR-net network were used to align and quantify the 3D images,obtaining high-density 3D facial point cloud data.After unsupervised clustering of the point cloud,principal component analysis was applied to reduce dimensionality and extract multidimensional morphological phenotypes for each facial region.Based on these multidimensional phenotypes,partial least squares regression(PLSR)and canonical correlation analysis(CCA)were used for genetic association analysis.Results A total of 10 SNPs were validated to be significantly associated with facial morphology in Han Chinese,of which 7 SNPs were validated by the PLSR method,2 SNPs were validated by the CCA method,and 1 SNP was validated by both methods.Conclusion Among the 10 significantly associated SNP sites,9 related facial morphological regions were consistent with previous reports in other populations,indicating that genes affecting complex facial morphology have cross-population effects.

Objective:To investigate the impact of perceived barriers to cardiac rehabilitation on adherence to cardiac rehabilitation and the mediating effect of cardiac impact denial in elderly patients after percutaneous coronary intervention (PCI) .Methods:This study was a cross-sectional survey. From August 2023 to July 2024, 336 elderly patients with PCI who were discharged from the First Affiliated Hospital of Wenzhou Medical University and needed phaseⅡ cardiac rehabilitation were selected for the study. General Information Questionnaire, Adherence of Cardiac Rehabilitation Assessment Scale in Patients with Coronary Heart Disease (ACRAS-CHD) , Cardiac Rehabilitation Barriers Scale (CRBS) , and Cardiac Denial of Impact Scale (CDIS) were used to survey the patients. Bootstrap method was used to sample 5 000 for mediating effect tests.Results:A total of 336 questionnaires were distributed and 324 valid questionnaires were recovered, with a valid recovery rate of 96.43% (324/336) . Among 324 elderly patients after PCI, ACRAS-CHD score, CRBS score, and CDIS score were (73.19±5.46) , (79.35±6.60) , and (30.57±3.66) , respectively. The direct effect of perceived barriers to cardiac rehabilitation on adherence to cardiac rehabilitation in elderly patients after PCI was -0.368, which accounted for 74.49% (-0.368/-0.494) of the total effect. The mediating effect of cardiac impact denial between perceived barriers to cardiac rehabilitation and adherence to cardiac rehabilitation in elderly patients after PCI was -0.126, which accounted for 25.51% of the total effect (-0.126/-0.494) .Conclusions:Elderly patients after PCI have poor adherence to cardiac rehabilitation. Perceived cardiac rehabilitation barriers reduce cardiac rehabilitation adherence in elderly patients after PCI, and cardiac impact denial exerts a partial mediating effect between perceived cardiac rehabilitation barriers and cardiac rehabilitation adherence.

OBJECTIVE To analyze the manager post competency evaluation scale in central sterile supply depart-ment based on the iceberg model and test its reliability and validity.METHODS A pool of items was constructed based on literature research and semi-structured interviews.The scale was further refined through expert meetings and a pilot survey.A convenience sampling method was used to select 362 managers from central sterile supply de-partments in medical institutions at various levels in Hunan Province in Jan.2024 as survey subjects.Question-naires were administered,and the reliability and validity of the scale were tested.RESULTS The final version of the scale encompassed five dimensions:personal traits,management abilities,professional abilities,other abili-ties,professional knowledge and skills,with a total of 39 items.The item-level validity coefficients of the scale ranged from 0.83 to 1.00,and the content validity index was 0.93.Exploratory factor analysis revealed a Bartlett's test value of 4 723.828(P＜0.001),a KMO test coefficient of 0.937 and a cumulative variance explanation rate of 74.34％for the five common factors.Confirmatory factor analysis results indicated that the root mean square error of approximation(RSEMA)was＜0.08,the root mean square residual(RMR)was＜0.05,and both the incre-mental fit index(IFI)and comparative fit index(CFI)were＞0.9.The Cronbach's α coefficient of the scale was 0.977,the split-half reliability was 0.955,and the test-retest reliability was 0.952.CONCLUSIONS The manager post competency evaluation scale in central sterile supply departments developed in this study demonstrates rela-tively good reliability and validity.It can effectively evaluate manager post competency and provide references for improving related evaluation systems and optimizing training programs.

BackgroundSevere mental disorders are characterized by high recurrence rate， high disability rate， high rates of harmful incidents， and low treatment-seeking rate， with affected patients demonstrating increased frequencies of dangerous behaviors. Ningxia Hui Autonomous Region has implemented community management for patients with severe mental disorders across the region since 2004， while the current status and regional characteristics of the managed patients remain unclear. ObjectiveTo analyze the current status of management and treatment of patients with severe mental disorders in Ningxia Hui Autonomous Region， and to explore their regional distribution characteristics， so as to provide references for optimizing regional prevention and control strategies. MethodsPatients with severe mental disorders diagnosed and registered in the Severe Mental Disorder Management Information Platform of Ningxia Hui Autonomous Region from August 1， 2011 to December 31， 2021 were selected. Patients' basic information， management indicators， and treatment metrics were extracted from the platform， followed by descriptive statistical analysis of the corresponding data. ResultsAs of December 31， 2021， the permanent resident population of Ningxia Hui Autonomous Region was 6 946 540， with 29 787 registered patients with severe mental disorders. The majority of the patients were female （50.25%）， aged 18-59 years （79.01%）， with educational level of junior high school or below （84.63%）， married （52.87%）， farmers （56.01%）， and diagnosed with schizophrenia （55.91%）， while ethnic minority patients accounted for a relatively high proportion （31.35%）. In 2021， the reported prevalence rate of severe mental disorders in Ningxia Hui Autonomous Region was 0.43%， with standardized management and regular medication adherence rates at 90.39% and 66.34%， respectively. The standardized management rate in 8 counties/districts （36.36%） was lower than the average level of Ningxia Hui Autonomous Region， while 10 counties/districts （45.45%） showed below-average medication adherence rates， of which 6 counties/districts（60.00%） were located in the south-central region. ConclusionPatients with severe mental disorders in Ningxia Hui Autonomous Region are predominantly young and middle-aged adults with low level of education， and those in the central-southern region demonstrate lower medication adherence. ［Funded by Key Research and Development Program Project of Ningxia Hui Autonomous Region （number， 2023BEG02029）］

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.
