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.

Objective:To explore the correlation between the ratio of serum free triiodothyronine/free thyroxine (FT3/FT4) and carotid atherosclerosis in a population undergoing physical examination.Methods:This retrospective cross-sectional study consecutively enrolled 4 031 adult healthy examinees who underwent both carotid ultrasound and serum thyroid hormone level testing at the Health Management Center of Shengjing Hospital Affiliated to China Medical University from January 2017 to December 2023. The general information, anthropometric measurements, and related laboratory indicators were collected. Based on carotid ultrasound results, the participants were divided into carotid atherosclerosis group (2 382 cases) and non-carotid atherosclerosis group (1 649 cases). According to the median FT3/FT4 ratio (0.35), participants were further categorized into a high FT3/FT4 ratio group (1 998 cases) and a low FT3/FT4 ratio group (2 033 cases). Receiver operating characteristic (ROC) curve analysis was performed to assess the diagnostic value of serum FT3/FT4 levels for carotid atherosclerosis. Additionally, the carotid atherosclerosis group was subdivided into carotid intima-media thickness (CIMT) thickening group (1 006 cases) and plaque formation group (1 376 cases). Stepwise logistic regression analysis was used to assess the correlation between FT3/FT4 levels and different severity of carotid artery stiffness.Results:Among the 4 031 health examinees included in the study, the detection rate of carotid atherosclerosis was 59.09% (2 382/4 031). The FT3/FT4 ratio in the carotid atherosclerosis group was significantly lower than that in the non-carotid atherosclerosis group (0.34 vs 0.39, Z=-19.958, P<0.001). The incidence rate of carotid atherosclerosis in the high FT3/FT4 ratio group was significantly lower than that in the low FT3/FT4 ratio group (46.7% vs 71.3%, Z=251.797, P<0.001). Multivariate regression analysis revealed that the FT3/FT4 ratio was an independent protective factor for carotid atherosclerosis ( OR=0.493, 95% CI: 0.458-0.529), with a protective effect comparable to high-density lipoprotein cholesterol ( OR=0.659, 95% CI: 0.543-0.801), while fasting blood glucose ( OR=1.566) and low-density lipoprotein cholesterol ( OR=1.164) were risk factors. ROC curve analysis showed that the area under the curve (AUC) of the FT3/FT4 ratio for diagnosing carotid atherosclerosis was 0.685 (sensitivity 79.3%, specificity 50.2%, cutoff value 0.39). In the analysis of carotid atherosclerosis subtypes, the FT3/FT4 ratio in the plaque formation group (0.328) was significantly lower than that in the CIMT thickening group (0.360) and the non-stiffness group (0.391)(all P<0.001), and it exhibited a stronger protective effect against plaque formation ( OR=0.297, 95% CI: 0.256-0.344). Conclusion:The FT3/FT4 ratio shows a dose-response relationship with the severity of carotid artery sclerosis and can serve as an auxiliary screening indicator for individuals at high cardiovascular risk. To enhance diagnostic efficacy, it is recommended to integrate this measure with other metabolic indicators.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Purpose: The purpose of this study was to use data mining methods to establish a simple and reliable predictive model based on the risk factors related to gallbladder stones (GS) to assist in their diagnosis and reduce medical costs. Materials and Methods: This was a retrospective cross-sectional study. A total of 4215 participants underwent annual health examinations between January 2019 and December 2019 at the Physical Examination Center of Shengjing Hospital Affiliated to China Medical University. After rigorous data screening, the records of 2105 medical examiners were included for the construction of J48, multilayer perceptron (MLP), Bayes Net, and Naïve Bayes algorithms. A ten-fold cross-validation method was used to verify the recognition model and determine the best classification algorithm for GS. Results: The performance of these models was evaluated using metrics of accuracy, precision, recall, F-measure, and area under the receiver operating characteristic curve. Comparison of the F-measure for each algorithm revealed that the F-measure values for MLP and J48 (0.867 and 0.858, respectively) were not statistically significantly different (p>0.05), although they were significantly higher than the F-measure values for Bayes Net and Naïve Bayes (0.824 and 0.831, respectively; p<0.05). Conclusion The results of this study showed that MLP and J48 algorithms are effective at screening individuals for the risk of GS.The key attributes of data mining can further promote the prevention of GS through targeted community intervention, improve the outcome of GS, and reduce the burden on the medical system.

Atrial fibrillation (AF) is the most common supraventricular arrhythmia, characterized by high morbidity and mortality.The mechanism of AF is not very clear, and there is still a lack of effective radical treatments.Therefore, the prevention of AF is particularly important.Different dietary patterns are closely related to the occurrence and development of AF.This study reviewed the relationships of different dietary factors such as the Mediterranean diet, the Dietary Approaches to Stop Hypertension (DASH diet), fish and ω-3 polyunsaturated fatty acids, olive oil, nuts, caffeine, chocolate, alcohol, fried food and salt with the occurrence of AF, and explored its mechanism of action.

Osteosarcoma is a kind of bone tumor with highly proliferative and invasive properties, a high incidence of pulmonary metastasis and a poor prognosis. Chemotherapy is the mainstay of treatment for osteosarcoma. Currently, there are no molecular targeted drugs approved for osteosarcoma treatment, particularly effective drugs for osteosarcoma with pulmonary metastases. It has been reported that fibroblast activation protein alpha (FAPα) is upregulated in osteosarcoma and critically associated with osteosarcoma progression and metastasis, demonstrating that FAPα-targeted agents might be a promising therapeutic strategy for osteosarcoma. In the present study, we reported that the FAPα-activated vinblastine prodrug Z-GP-DAVLBH exhibited potent antitumor activities against FAPα-positive osteosarcoma cells in vitro and in vivo. Z-GP-DAVLBH inhibited the growth and induced the apoptosis of osteosarcoma cells. Importantly, it also decreased the migration and invasion capacities and reversed epithelial-mesenchymal transition (EMT) of osteosarcoma cells in vitro and suppressed pulmonary metastasis of osteosarcoma xenografts in vivo. Mechanistically, Z-GP-DAVLBH suppressed the AXL/AKT/GSK-3β/β-catenin pathway, leading to inhibition of the growth and metastatic spread of osteosarcoma cells. These findings demonstrate that Z-GP-DAVLBH is a promising agent for the treatment of FAPα-positive osteosarcoma, particularly osteosarcoma with pulmonary metastases.

Objective  To analyze the prevalence and risk factors of hyperuricemia (HUA) in Shenyang City, and to provide evidence for the prevention and treatment of HUA in this region. Methods From January 2013 to December 2020, 98,327 subjects who underwent physical examination in Shengjing Hospital of China Medical University in Shenyang were selected. The detection rate of HUA was calculated, and the risk factors of HUA were analyzed by multivariate logistic regression analysis. Results From 2013 to 2020, the overall prevalence of HUA was 22.48%, 30.75% in males and 9.13% in females. The prevalence rate in the male was significantly higher than that in the female (P<0.05). Except for a slight decrease in 2015 and 2020, the total prevalence rate showed an increasing trend year by year. With the increase of age, the prevalence of HUA in males decreased, while in females, it decreased slightly from 40 to 59 years old and increased significantly after 60 years old. With the increase of BMI (Body Mass Index), the prevalence of HUA also increased, and the difference was statistically significant (P<0.05). Logistic regression analysis showed that male, body mass index, physical examination year, hypertension, hyperlipidemia, hyperglycemia, triglyceride, LDL-C, abnormal liver and renal function were positively correlated with HUA, while age and HDL-C were negatively correlated with HUA. Conclusion  HUA occurs mainly in male people among physical examination population in Shenyang. With the increase of BMI, HUA increases.
