Objective: To analyze the prevalence status and clustering patterns of risk factors for chronic diseases among adult residents in Rui' an City, Zhejiang Province, so as to provide a basis for formulating strategies for the prevention and control of chronic diseases and implementing risk factor interventions. Methods: A multi-stage random cluster sampling method was used to select residents aged ≥18 years in 5 townships (sub-districts) of Rui' an City as survey subjects from December 2023 to March 2024. Data on basic information, history of major chronic diseases, lifestyle behaviors, height, weight, and blood biochemical indicators were collected through questionnaire surveys, physical examinations, and laboratory tests. Descriptive analysis was used to analyze the prevalence status of 5 risk factors for chronic diseases. K-means clustering analysis was used to analyze clustering patterns. Results: A total of 3 060 people were surveyed, including 1 476 males, accounting for 48.24%, and 1 584 females, accounting for 51.76%. The median age was 49.00 (interquartile range, 25.00) years. There were 1 275 cases (41.67%) of hypertension, 462 cases (15.10%) of diabetes, and 1 460 cases (47.71%) of dyslipidemia. Insufficient fruit and vegetable intake, excessive salt intake, overweight and obesity, excessive red meat intake, and smoking involved 2 201, 1 878, 1 541, 1 337, and 571 people, with prevalences of 71.93%, 61.37%, 50.36%, 43.69%, and 18.66%, respectively. K-means clustering analysis identified 4 clustering patterns: smoking-insufficient fruit and vegetable intake type (249 people, accounting for 8.20%), low intake type (1 421 people, accounting for 46.75%). high red meat type (245 people, accounting for 8.07%), and high BMI-high salt type (1 118 people, accounting for 36.96%). The prevalences of hypertension and diabetes were higher in adult residents of the high BMI-high salt type, at 56.53% and 20.30%, respectively. The prevalence of dyslipidemia was higher in adult residents of the smoking-insufficient fruit and vegetable intake type, at 59.44%. Conclusions The prevalence of insufficient fruit and vegetable intake among adult residents in Rui' an City is relatively high. The clustering pattern of chronic disease risk factors is dominated by the low intake type. The prevalence of chronic diseases is higher in adult residents of the high BMI-high salt type and smoking-insufficient fruit and vegetable intake type. It is suggested to carry out health education and collaborative intervention of risk factors for different risk groups.

With changes in lifestyle,the incidence of osteoporotic vertebral burst fractures is increasing.These fractures are prone to being underdiagnosed or misdiagnosed.In severe cases,they can lead to nonunion,kyphotic deformity,and even neurological injury.The best treatment plan for such unstable fractures has always been controversial.On the one hand,the fracture degree is severe and the morphology is complex,and there is no unified classification standard.On the other hand,the general condition and bone quality of the patients are poor,which affects the surgical decision.This article reviews the progress in the diagnosis and treatment of osteoporotic lumbar body blowout fractures.

Objective To assess the mid-term clinical prognosis and radiological outcomes of a novel expandable PEEK(polyetheretherketone)vertebral replacement device used for anterior and middle column recon-struction in the thoracolumbar spine of osteoporotic patients.Methods A retrospective analysis was performed on 52 patients with single-segment osteoporotic thoracolumbar fractures who underwent vertebral body replacement surgery between January 2020 and December 2023.The surgical procedures included either a thoracoscopic or minimally invasive anterior approach,combined with posterior short-segment cement-augmented screw fixation.According to the type of replacement material used,patients were categorized into two groups:the novel PEEK group and the titanium Mesh cage group.Data on surgical time,intraoperative blood loss,and postoperative complications were collected.The Visual Analogue Score(VAS),Oswestry Disability Index(ODI),local kyphotic angle(LKA),fusion segment height(D-line),anterior vertebral body height(AVBH),and posterior vertebral body height(PVBH)were assessed at three stages:preoperatively,immediately postoperatively,and during the final follow-up.Results All patients were successfully discharged.In the PEEK group,the average operative time was(235.28±58.69)minutes,and intraoperative blood loss was(680.00±163.30)mL.The mean follow-up duration was(14.12±2.44)months.The VAS score decreased significantly from(7.44±0.87)preoperatively to(2.24±0.93)at the final follow-up,and the ODI score also decreased significantly from(42.64±4.86)preoperatively to(11.84±3.73)at the final follow-up,indicating substantial improvement in symptoms and function(P<0.05).At the final follow-up,LKA,D-line,and AVBH exhibited partial loss compared to immediate postoperative values(P>0.05),but they remained significantly improved compared to preoperative values(P<0.05).The postoperative complication rate was 12.00%(3/25),and the fusion rate at the final follow-up was 100.00%.Similarly,the Mesh group effectively improved patient symptoms,function,and vertebral height(P<0.05).However,at the final follow-up,the PEEK group demonstrated significantly better LKA,D-line,and AVBH values compared to the Mesh group(P<0.05).Conclusion The short-segment cement-augmented internal fixation in combination with the novel expandable PEEK replacement device represents a viable solution for anterior column reconstruction in osteoporotic thoracolumbar fractures,as evidenced by its mid-term outcomes of effective pain relief,significant functional improvement,sustained maintenance of vertebral height,and successful deformity correction.

Objective To explore the efficiency improvement in segmenting neural network with the application of Transformer + U-Net artificial intelligence (AI) and modeling with the application of Python scripts in three-dimensional (3D) printing brachytherapy. Methods A Transformer + U-Net AI neural network model was constructed, and Adam optimizer was used to ensure rapid gradient descent. Computed tomography or magnetic resonance imaging data of patients were standardized and processed as self-made data sets. The training set was used to train AI and the optimal result weight parameters were saved. The test set was used to evaluate the AI ability. Python programming language was used to write an automated script to obtain the output segmentation image and convert it to the STL file for import. The source applicator and needle could be automatically modeled. The time of automatic segmentation and modeling and the time of manual segmentation and modeling were entered by two people, and the difference was verified by paired t-test. Results Dice similarity coefficient (DSC), mean intersection over union (MIOU), and Hausdorff distance (HD95) were used for evaluation. DSC was 0.9341, MIOU was 0.8762, and mean HD95 was 2.516. The mean time of manual segmentation was 1187 s, and the mean time of AI segmentation was 145 s (P < 0.01). The mean time of manual modeling was 321 s, and the mean time of modeling with Python automated scripts was 18 s (P < 0.01). Conclusion The application of Transformer + U-Net automatic segmentation and Python automated scripts can effectively improve work efficiency in the 3D printing brachytherapy for cervical cancer.

Objective: This study explored whether anxiety and core self-evaluation mediate the relationship between negative life events and depressive symptoms in adolescents of the Yi ethnic minority in China. Methods: In this cross-sectional study, a convenience sample of 627 Yi adolescents 10–19 years old (252 males, 40.2%) from primary, middle and high schools in Liangshan Prefecture in China completed the Adolescent Self-Rating Life Events Checklist (ASLEC) to report on negative life events, the Second Edition of the Beck Depression Inventory (BDI-II) to report on depressive symptoms, the Core Self-Evaluations Scale (CSES) to describe core self-evaluation, and the Screen for Child Anxiety-Related Emotional Disorders (SCARED) to report anxiety symptoms. Results: In Pearson correlation analysis, total score and dimension subscores on the ASLEC correlated positively with total score and dimension subscores on the SCARED survey as well as with total score on the BDI. Total ASLEC score and dimension subscores correlated negatively with total CSES score. Mediation analysis indicated that negative life events affected depressive symptoms directly, as well as indirectly via core self-evaluation (mediating effect was 0.087; 95% confidence interval [CI], 0.063–0.113; p<0.001). The chain-mediated pathway effect was significant (mediating effect was 0.017; 95% CI, 0.011–0.026; p<0.001). Conclusion Yi adolescents in Liangshan Prefecture show certain prevalence of anxiety and depression, and they score relatively low on core self-evaluation. In this ethnic group, negative life events can affect depressive symptoms directly as well as indirectly through chain-mediated effects of anxiety and core self-evaluation.
