Objective:To analyze the three-dimensional radiographic characteristics of solid variant of odontogenic keratocyst(SOKC)using multi-slice spiral tomography(MSCT).Methods:Clinical records,histopathological reports and MSCT images of 8 patients were retrospectively acquired,radiographic features,including lesion site,size,borders,jaw expansion,internal structures and relationship with surrounding tissues were analyzed.Results:8 cases(4 males and 4 females)aged 37-65 years were included.Among them,4 lesions were located in the maxilla and the other 4 in mandible.Clinically,the lesions manifested as an enlargement of the affected area in the jaw bone,with pain present in 6 cases.On MSCT scans,all lesions showed evident jaw expansion.The boundaries of the lesions were clear in 3 cases,and unclear in 5 cases.4 cases exhibited multilocular radiolucent lesions,while the other 4 cases showed mixed radiolucent/opaque lesions resembling fibro-osseous lesion.The maxilla lesions involved the palate,na-sal cavity,maxillary sinus and orbital floor.All mandible SOKCs were recurrent and infectious,with involvement of the surrounding soft tissue.Conclusion:SOKC exhibits imaging characteristics that differentiate from conventional odontogenic keratocysts.Radio-graphically,it presents as a benign or low-grade malignant solid jaw mass.

Objective To extract the core elements and connotation definitions of the concept of organizational resilience of County Medical Community (CMC),in order to explore effective ways to enhance the organizational resilience of CMC.Methods Based on the Atomic spectrum,as of October 31,2023,52 articles related to organizational resilience in the health system were included for concept images extraction,calculating the frequency and occurrence rate of concept images,extracting the concept of organizational resilience in the health system,and deducing the core elements and definitions of the concept of organizational resilience in CMC were derived through the comparison of similarities and differences.Results Although both the healthcare system and the CMC are composite organizations,there are differences in environmental pressure,organizational size,and resource reserves.The concept of organizational resilience of CMC is defined as the advanced process of resilience functions exhibited by CMC in response to emergencies,internal and external threats,and social pressures that constrain the sustainable development of the organization,including redundant preparation,stable recovery,and response to growth,as well as their ability to absorb,adapt,and transform disruptive events.This not only maintains the basic structure and functions of the organization,but also enables the organization to grow against the trend.Conclusion Breaking through the traditional hierarchical structure in terms of structural resilience,achieving a deep integration and coordination mechanism of the medical community horizontally and vertically.Breaking through traditional static planar functions in terms of functional resilience,enhancing the driving force within the medical community through dynamic growth mechanisms.

Objective Establish a relationship model between the outcome of inpatient rehabilitation treatment and the influencing factors of rehabilitation effect,explore the evaluation method of inpatient rehabilitation service effect.Methods Using a neural network model to construct a functional relationship model between the outcomes of inpatient rehabilitation treatment and the factors affecting rehabilitation effectiveness,in order to predict the expected rehabilitation outcomes of patients receiving inpatient treatment.Compare the distribution of the difference between the actual discharge ICF total score and the predicted ICF total score to determine the effectiveness of rehabilitation treatment.Results As a result,a total of 1 334 hospitalized rehabilitation cases of brain injury patients were included in this study for analysis.Based on the evaluation indicators and standards of prediction accuracy,the optimal model was selected and the rehabilitation effect was evaluated.Conclusion Based on the ICF-RS-17 measurement of patient entry and exit function scores,the functional status of hospitalized rehabilitation patients themselves,and related possible influencing factors,a relationship model between inpatient rehabilitation treatment outcomes and influencing factors is constructed.It provides a certain scientific basis for establishing an effective evaluation method for the actual clinical rehabilitation effect,and also provides reference suggestions for the realization of value-based payment of rehabilitation medical insurance.

AIM:This study aims to investigate the expression and prognostic value of ubiquitin-conjugating enzyme E2C(UBE2C)in hepatocellular carcinoma(HCC),and to explore its impact on cancer stemness and the regulato-ry mechanisms.METHODS:(1)The TCGA and GEO databases were used to analyze UBE2C mRNA expression levels in HCC tissues and their correlation with prognosis using bioinformatics techniques,and these findings were further vali-dated in postoperative specimens from 107 HCC patients.The GEPIA database was used to analyze the correlation be-tween UBE2C and steroid receptor coactivator(SRC).(2)The CCK8,colony formation,wound healing,and spheroid formation assays were used to assess the effects of UBE2C on HCC cell proliferation,migration,and stemness.The inter-action between UBE2C and signal transducer and activator of transcription 3(STAT3),as well as its regulatory mecha-nism,was examined by Western blot and co-immunoprecipitation assays.(3)The subcutaneous xenograft model in nude mice was employed to validate the role of UBE2C in tumor growth in vivo.RESULTS:(1)Bioinformatics analysis re-vealed that UBE2C expression was significantly up-regulated in HCC tissues compared with adjacent normal tissues(P<0.05 in TCGA,and P<0.01 in GEO).Consistently,analysis of HCC specimens confirmed that high UBE2C expression was associated with shortened overall survival and disease-free survival of HCC patients(P<0.05).Furthermore,analysis using the GEPIA database revealed a positive correlation between UBE2C and SRC(P<0.01).(2)In vitro experiments demonstrated that UBE2C significantly promotes the proliferation and migration of HCC cells.Based on these findings,we presumed that UBE2C may regulate the phosphorylation of STAT3 at the Y705 site by modulating SRC activity,thereby in-fluencing the stemness characteristics of tumor cells.(3)In vivo experiments further confirmed that UBE2C inhibition sig-nificantly suppressed tumor growth.CONCLUSION:The UBE2C promoted proliferation and migration of HCC cells and regulated the stemness of HCC cells by interacting with STAT3.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.
