Objective:To provide theoretical support and practice model for improving the clinical medical education supervision system of university-affiliated hospitals.Methods:This study focused on the group of reserve teaching supervision experts. Through literature research, questionnaire survey, and expert interview, the Competency Evaluation Criteria for Reserve Teaching Supervision Experts was constructed, which was implemented according to the training framework of "theory, practice, summary, and feedback". The paired t-test was performed using SPSS 24.0. Results:The research team formulated the Competency Evaluation Criteria for Reserve Teaching Supervision Experts through expert interviews. Six basic competencies and three advanced competencies for reserve teaching supervision experts were identified and their weights were assigned. A supervision team was established with supervision experts (including reserve teaching supervision experts) and teaching staff at a ratio of 1∶6.9, achieving an increase in the coverage of supervised specialties. A toolkit for enhancing the supervision capabilities of reserve experts was developed, and its effectiveness was analyzed. Statistical analysis showed that the overall score gap between reserve teaching supervision experts and senior supervision experts gradually narrowed. In terms of teaching demeanor and teaching effectiveness, there were no significant differences between the two types of experts. However, in terms of teaching content scores, there was a significant difference between reserve teaching supervision experts and senior supervision experts ( P<0.05). Conclusions:The training mechanism of reserve teaching supervision experts can effectively bridge the structural defects of the traditional supervision team. However, further emphasis is needed on the standardization and professionalization of teaching content supervision.

Objective To evaluate the efficacy of an online-to-offline(O2O)health education guided by the'Timing Theory'in improving self-management behaviours among the patients with glaucoma after day surgery.Methods In this randomised controlled study conducted between July and December 2022,70 patients with glaucoma after day surgery in our hospital were assigned to a control group and an experimental group,with 35 patients per group.Patients in control group received routine nursing care,while those in experimental group received O2O health education based on timing theory in addition to the routine nursing care.Outcomes were evaluated using the glaucoma awareness and knowledge questionnaire(GAKQ),self-efficacy to manage chronic disease scale(SEMCD)and glaucoma self-management questionnaire(GSMQ)at baseline,at 1 month and 3 months after surgery.Results A total of 32 patients in the experimental group and 27 in the control group completed the study.The generalised estimating equation(GEE)analysis showed a significant difference,respectively,in total score of GSMQ in interaction effect(F=8.408,P=0.015)and SEMC in time main effect(F=54.660,P<0.001).There were significant differences in total scores of GAKQ in time main effect,inter-group main effect and interaction effect(F=128.483,P<0.001;F=7.991,P<0.05;F=32.652,P<0.001,respectively).At one-month after intervention,the experimental group showed significantly higher GAKQ and SEMCD scores than the control group(Z=-2.004,P<0.05;Z=-2.029,P<0.05,respectively).At 1-and 3-months after intervention,the experimental group demonstrated significantly higher GAKQ scores(Z=-3.987,P<0.001;Z=-4.505,P<0.001,respectively).Conclusion The timing theory based O2O health education significantly improves knowledge of glaucoma,self-efficacy and self-management behaviours among day surgery patients and helps patients better cope with perioperative self-management over day surgery.

Objective:To test the difficulty, discrimination, and reliability of the ICU Nurse Pressure Injury Prevention and Care Knowledge Questionnaire.Methods:Two researchers independently translated the ICU Nurse Pressure Injury Prevention and Care Knowledge Questionnaire and cross-checked it to form a Chinese version of the questionnaire. The Chinese version of the ICU Nurse Pressure Injury Prevention and Care Knowledge Questionnaire consists of 24 items, with correct answers scoring one point and incorrect answers scoring zero points, with a total score of 24 points. Convenience sampling was used to select ICU nurses from 14 GradeⅢ Class A hospitals in five provinces/autonomous regions and two municipalities in China for the survey between April and July 2023. The difficulty index, discrimination index, and Cronbach's α coefficient of the questionnaire were analyzed.Results:A total of 1 121 questionnaires were distributed, with 1 020 valid responses, yielding a valid response rate of 90.99%. The mean score of the 1 020 ICU nurses on the Chinese version of the ICU Nurse Pressure Injury Prevention and Care Knowledge Questionnaire was (16.10±5.58) , with a minimum score of 4.00 and a maximum score of 24.00. The Cronbach's α coefficient of the Chinese version of the ICU Nurse Pressure Injury Prevention and Care Knowledge Questionnaire was 0.91. The questionnaire's overall difficulty and discrimination indexes were 0.67 and 0.59, respectively.Conclusions:The Chinese version of the ICU Nurse Pressure Injury Prevention and Care Knowledge Questionnaire has appropriate difficulty, moderate discrimination, and strong reliability, making it a valuable tool for assessing ICU nurses' knowledge of pressure injury-related topics.

OBJECTIVE To mine the cardiovascular safety signal of relugolix， and provide a reference for the listing of this drug in China and future clinical safety drug evaluation. METHODS The adverse event （AE） report data of relugolix， as the primary or secondary suspected drug， was collected from the FDA Adverse Event Reporting System （FAERS） from the first quarter of 2021 to the third quarter of 2023. The reporting odds ratio （ROR） method was used for data mining. The AEs in the FAERS database were identified and coded using preferred terms （PT） stated in version 24.0 of the Medical Dictionary for Drug Regulatory Activities （MedDRA）. The AEs of the target drug were identified by the narrow standardized MedDRA query （SMQ） terms and high-level term （HLT）. Sensitivity analysis was conducted using AEs suspected to be primarily or secondarily related to relugolix or related to drug interaction and concomitant drug， and broad SMQ terms. RESULTS A total of 4 354 relugolix-related AE reports were extracted. In the primary analysis， nine SMQ terms were analyzed， involving 2 positive signals such as dyslipidemia and hyperglycemia/new onset diabetes mellitus. Eleven HLTs were analyzed， and three positive signals were detected for three terms including cholesterol analyses， triglyceride analyses and hyperglycemia conditions （non-alternative analysis）. Sensitivity analysis results indicated the reliability of the study findings. CONCLUSIONS Relugolix may induce risk signals related to high blood lipids and high blood glucose， but no moderate risk signals such as hypertension， heart disease， and stroke are found. During relugolix treatment in clinical practice， attention must be paid to hyperlipidemia and hyperglycemia-related AE.

Chewing-side preference is one of the risk factors for temporomandibular disorders (TMD), and people with chewing-side preference is more prone to have short and displaced condyles, increased articular eminence inclination and glenoid fossa depth. The proportion of TMD patients with chewing-side preference is often higher than that of the normal subjects. Clinical studies have shown a strong correlation between chewing-side preference and TMD symptoms and signs; and animal studies have shown that chewing-side preference can affect the growth, development, damage and repair of the mandible. After long-term unilateral mastication, changes in the stress within the joint cause the imbalance of temporomandibular joint (TMJ) structural reconstruction, the transformation and even destruction of the fiber structure of masticatory muscle, resulting in uncoordinated movement of bilateral muscles. The joint neurogenic diseases caused by the increase of neuropeptide substance P and calcitonin-gene-related-peptide (CGRP) released locally by TMJ may be the mechanism of TMD. This article reviews the research progress of the influence of chewing-side preference on the structure of TMJ, the relationship between chewing-side preference and TMD, and the related mechanisms.
