Objective To explore the influence of 3D printed individualized tissue compensators on the dose of the radiotherapy target area and the radiotherapy accuracy in intensity-modulated radiotherapy for vul-var carcinoma.Methods Twenty patients with vulvar cancer who visited this hospital from December 2022 to December 2024 were selected as the research subjects and divided into the control group and 3D group accord-ing to the random number table method,10 cases in each group.The control group used the conventional tis-sue compensators,while the 3D group used the 3D printed individualized tissue compensators.The dosimetric results of the target area and normal tissues were compared between the two groups.Results Compared with the control group,the maximum dose[(5 501.00+22.12)cGy vs.(5 659.60+84.59)cGy],average dose[(5 203.60+52.45)cGy vs.(5 258.70+42.95)cGy]and dose of 2％target volume[(5 360.30+63.70)cGy vs.(5 408.90+91.90)cGy]in the 3D group were lower,and the homogeneity index(0.12+0.01 vs.0.13+0.02)and conformity index(1.16+0.05 vs.1.23+0.04)were better,and the differences were statistically significant(P＜0.05).There was no statistically significant difference in dose of 30％clinical target volume of the bladder and rectum between the two groups(P＞0.05).During and after radiotherapy,among 20 cases,4 cases presented with grade 3 skin reactions,which were wet peeling,with 2 cases in each of the two groups.The remaining 16 cases had the grade 1 to 2 skin reactions.Conclusion In intensity-modulated radiotherapy for vulvar carcinoma,the dose distribution of 3D-printed personalized tissue compensators is superior to that of conventional organizational compensators.

Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.

Objective:To investigate the application effect of entrustable professional activities (EPAs) in competency evaluation of dermatology residents, to practice the goal of hierarchical progressive training for EPAs competency in dermatology residents, and to improve the competency of physicians.Methods:A questionnaire survey was conducted among 8 clinical instructors and 165 residents who received standardized residency training in Department of Dermatology, The First Affiliated Hospital of Jinzhou Medical University, from September 2019 to September 2022, and self-assessment and trainer-assessment were performed based on EPAs. The Kruskal-Wallis H test and the Mann-Whitney U test were used for comparison of entrustable level between the dermatology residents of different grades. Results:The scores of both trainer-assessment and self-assessment based on EPAs increased with the increase in the grade of the resident physicians, and the resident physicians of the third year (the PGY3 group) had the highest levels of trainer-assessment and self-assessment based on EPAs. The resident physicians of all grades showed relatively low assessment scores of EPA4 (making a medical decision), EPA8 (recognize a patient requiring urgent or emergent care and initiate evaluation and management), EPA14 (clinical teaching), and EPA15 (public health events management). There were significant differences in all EPAs items of trainer-assessment and self-assessment between the residents of different grades (Kruskal-Wallis test, P<0.05). There was a significant difference in trainer-assessment between PGY1 and PGY2 and between PGY1 and PGY3 (Bonferroni P correction, P<0.05), while there was no significant difference between the PGY2 and PGY3 groups ( P>0.05). Conclusions:There are differences in the evaluation of EPAs in dermatology residents of different grades, and hierarchical progressive training of EPAs competency can effectively improve the clinical competency of dermatology residents. Given the inconsistency between the scores of self-assessment and trainer-assessment, it is necessary to improve the feedback plan in the future.

Objective: To investigate the relationship between depressive symptoms and frailty among middle-aged and elderly populations, so as to provide insights into the early identification and prevention of frailty. Methods: Based on the 2018 database of China Health and Retirement Longitudinal Study (CHARLS), demographic information, lifestyle and self-rated health status were collected from people aged 50 years and older. Depression symptoms were evaluated using the Short Version of Center for Epidemiological Studies Depression Scales (CES-D-10), and the frailty status was evaluated using frailty index. The relationship between depressive symptoms and frailty among middle-aged and elderly populations were using a multivariable logistic regression model, and the dose-response relationship was analyzed using a restricted cubic spline model. Results: A total of 5 172 individuals were enrolled, including 2 495 males (48.24%) and 2 677 females (51.76%), with a median age of 63.00 (interquartile range, 12.00) years, a median CES-D-10 score of 7.00 (interquartile range, 9.00) scores. There were 1 560 participants (30.16%) detected with mild depressive symptoms, 360 participants (6.96%) detected with moderate to severe depressive symptoms. Multivariable logistic regression analysis showed that after adjusting for gender, age, educational level, marital status, smoking, alcohol consumption and self-rated health status, participants who had mild depressive symptoms (OR=4.226, 95%CI: 3.625-4.928) and moderate to severe depressive symptoms (OR=10.737, 95%CI: 8.259-13.958) had a higher risk of frailty. The restricted cubic spline model showed a nonlinear relationship between depressive symptoms and frailty among middle-aged and elderly populations. When the CES-D-10 scores were greater than 7, the risk of frailty increased with higher CES-D-10 scores. Conclusion The degree of depressive symptoms in middle-aged and elderly people is associated with frailty, and there is a nonlinear relationship between the two.
