Objective To explore the risk factors for mineral and bone disorder in maintenance hemodialysis patients, and to construct and validate a nomogram prediction model. Methods A total of 306 patients undergoing maintenance hemodialysis at Shanghai Eighth People’s Hospital from January 2021 to May 2025 were selected as study subjects and randomly divided into a training set (n＝214) and a validation set (n＝92) in a 7∶3 ratio. In the training set, patients were divided into a normal bone mineral metabolism group and an abnormal bone mineral metabolism group, and related factors were compared between the two groups. The multivariate logistic regression analysis was used to identify the influencing factors of mineral and bone disorder in maintenance hemodialysis patients in the training set, and a nomogram prediction model was constructed. ROC curves were drawn to evaluate the ability of the nomogram model for predicting mineral and bone disorder in these patients. Calibration curves and Hosmer-Lemeshow goodness-of-fit test were used to analyze the consistency of the predictive probability of nomogram model and actual probability of mineral and bone disorder in these patients. The decision curve was used to assess the clinical benefit using nomogram prediction model. Results Among the 306 hemodialysis patients, 254 patients had mineral and bone disorder, accounting for 83.01%. Among the 214 patients in the training set, 177 had mineral and bone disorder, accounting for 82.71%. In the training set, age, gender, body mass index (BMI), hypertension rate, dialysis age, blood urea nitrogen (BUN), hemoglobin (Hb), albumin (ALB), alkaline phosphatase (ALP), serum creatinine (SCr), uric acid (UA), estimated glomerular filtration rate (eGFR), and rate of taking phosphate binders were statistically significant different between the two groups (P＜0.05). The multivariate logistic regression analysis showed higher age, female, hypertension, longer dialysis duration, decreased eGFR, and not taking phosphate binders were identified as risk factors for mineral and bone disorder in maintenance hemodialysis patients (P＜0.01). The nomogram prediction model was constructed. The area under the ROC curve of the model for mineral and bone disorder in the training set and validation set was 0.895 (95%CI 0.850-0.941) and 0.881 (95%CI 0.830-0.932), respectively, with maximum Youden indice of 0.650 and 0.600, sensitivity of 0.856 and 0.849, and specificity of 0.794 and 0.751. The Hosmer-Lemeshow test showed the nomogram prediction model had good consistency in predictive probabilities with actual probabilities in training set and validation set. The decision curve showed the nomogram model could bring clinical net benefits when the threshold probabilities in the training set and validation set were less than 0.96 and 0.91. Conclusions The nomogram prediction model constructed based on six independent risk factors including age, gender, hypertension, dialysis duration, eGFR, and using phosphate binders or not, shows good discrimination and calibration, with good clinical predictive ability, which could provide guidance for the management of maintenance hemodialysis patients.

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.

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 evaluate the therapeutic effectiveness of adult patients with Kashin-Beck disease (KBD) in Gansu Province, and provide guidance for rational and effective treatment of KBD patients.Methods:The KBD patients who participated in the "2021 Basic Public Health Service Subsidy Key Endemic Disease Prevention and Control Project" in Gansu Province were selected as the research subjects. Gender, age, clinical grading characteristics, and treatment plan selection of all subjects were analyzed, and the treatment effectiveness of KBD patients in different regions was evaluated.Results:A total of 6 711 KBD patients were included in the treatment program, including 3 139 males (46.8%) and 3 572 females (53.2%), 3 157 cases (47.0%) of patients aged 60 and 3 554 cases (53.0%) over 60 years old. There were 3 921, 2 166, and 624 patients with grades Ⅰ, Ⅱ, and Ⅲ, respectively, accounting for 58.4%, 32.3%, and 9.3%, respectively. The gender, age composition, and clinical grading among KBD patients included in different regions were compared, and the differences were statistically significant (χ 2 = 194.34, 47.44, 408.61, P < 0.001). In the distribution of treatment schemes, the number of patients who selected "drug treatment", "drug treatment combined with physical therapy", "drug treatment combined with acupuncture and moxibustion/massage", "drug treatment combined with acupuncture and moxibustion/massage combined with physical therapy", and "other treatment schemes" were 4 084 (60.9%), 726 (10.8%), 672 (10.0%), 443 (6.6%), and 786 (11.7%), respectively. The distribution of treatment plans in different regions was compared, and the difference was statistically significant (χ 2 = 1 088.38, P < 0.001). The total effective rate of KBD patients was 84.5% (5 668/6 711). The total effective rates of KBD patients with different clinical grades were ranked from high to low as grade Ⅲ (87.3%, 545/624), grade Ⅱ (86.4%, 1 871/2 166), and grade Ⅰ (82.9%, 3 252/3 921). The total effective rate of KBD patients with different treatment schemes from high to low was "drug treatment combined with acupuncture and moxibustion/massage combined with physical therapy" (91.0%, 403/443), "drug treatment combined with physical therapy" (87.1%, 632/726), "drug treatment" (86.7%, 3 539/4 084), "drug treatment combined with acupuncture and moxibustion/massage" (82.3%, 553/672), and "other treatment schemes" (68.8%, 541/786). The total effective rate of KBD patients in different regions, from high to low, was as follows: Linxia Hui Autonomous Prefecture (100%, 144/144), Qingyang City (88.7%, 3 562/4 017), Pingliang City (85.0%, 1 327/1 562), Gannan Tibetan Autonomous Prefecture (83.9%, 78/93), Dingxi City (70.9%, 151/213), Tianshui City (62.5%, 125/200), and Longnan City (58.3%, 281/482). The total effective rate of KBD patients in different clinical grades, treatment schemes, and regions was compared, and the differences were statistically significant (χ 2 = 16.95, 181.72, 435.80, P < 0.001). Conclusions:The overall effective rate of treatment for KBD patients in Gansu Province is relatively high, but there are significant differences in therapeutic outcomes among cities (prefectures); it is related to the treatment scheme and the clinical grading of patients. The scheme of "drug treatment combined with acupuncture and moxibustion/massage combined with physical therapy" has better efficacy.

Intelligent acupuncture-moxibustion medical equipment is an important force in promoting the inheritance, innovation, and modernization of acupuncture-moxibustion. This paper reviews the development status of intelligent acupuncture-moxibustion medical equipment and related new technologies, as well as the challenges faced. It is found that, with the advancement of technologies such as big data and artificial intelligence, acupuncture-moxibustion medical equipment has shown characteristics of greater precision, miniaturization, intelligence, and portability. However, deficiencies remain in areas such as standardization and regulation, including relatively low rates of effective transformation and a lack of innovation in research outcomes. Therefore, there is an urgent need to formulate corresponding strategies: improving the development of relevant standards for intelligent acupuncture-moxibustion medical equipment, encouraging the integration of medicine and engineering, cultivating interdisciplinary talents, and strengthening the protection of invention patents. It is necessary to establish a demand-oriented pathway connecting "equipment development, equipment evaluation, product formation" through multiple stages such as talent training and research project initiation, thereby promoting the modernization and standardization of intelligent acupuncture-moxibustion medical equipment and supporting the revitalization of traditional medicine.

Objective:To study the current prevalence and temporal patterns of Keshan disease in Gansu Province, thereby establishing a scientific foundation for development of targeted prevention and control strategies.Methods:From March 2019 to October 2021, monitoring of Keshan disease was conducted in all affected townships (towns) across 28 counties (districts, cities) in Gansu Province. Demographic data were collected from affected villages, and suspected chronic Keshan disease cases were identified through village clinics, township health centers, county hospitals, and other medical institutions. These suspected cases were diagnostically verified according to the "Diagnosis of Keshan Disease" (WS/T 210-2011). Current chronic Keshan disease cases underwent re-examination and follow-up monitoring.Results:There were a total of 254 endemic townships (towns) and 2 611 endemic villages across the province, with a permanent resident population of 3.667 1 million in the affected areas. New cases of chronic Keshan disease continued to emerge throughout the study period, totaling 6 cases. From 2020 to 2021, among the total number of chronic Keshan disease cases, 88.92% (923/1 038) remained stable in condition, while mortality cases accounted for 9.54% (99/1 038). Over the past three years, there were 886 males and 687 females with current chronic Keshan disease, mainly aged between 50 and 60 years old, accounting for 38.78% (610/1 573).Conclusions:While Keshan disease in Gansu Province maintains a sustained level of elimination, new chronic cases continue to emerge. It is essential to enhance disease surveillance efforts, and effectively consolidate the achievements in Keshan disease prevention and control measures.
