Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

BACKGROUND:Apoptosis and autophagy imbalance in the hippocampal region of perimenopausal depressed rats are closely related to cognitive decline.Whether aerobic exercise can reduce apoptosis by promoting hippocampal autophagy and thus improve the learning and memory abilities of perimenopausal depressed rats is not clear.OBJECTIVE:To investigate the possible mechanism by which 4-week moderate-intensity treadmill exercise improves learning memory ability in ovariectomized stressed rats.METHODS:Forty Sprague-Dawely rats were randomly divided into four groups,namely,sham operation group(n=10),ovariectomized group(n=10),ovariectomized stress group(n=10)and ovariectomized stress exercise group(n=10).Except for the sham operation group,the ovaries were removed in the other three groups to establish a perimenopausal rat model,and then a depressed rat model was established by chronic unpredictable stress in the latter two groups.The rats in the ovariectomized stress exercise group underwent a 4-week moderate-intensity treadmill exercise.Tail suspension test and sucrose preference test were performed to text depression-like behaviors in rats after exercise and stress.The eight-arm maze experiment was used to test the learning and memory behaviors of rats after exercise and stress.Western blot was used to detect the protein levels of AMP-activated protein kinase/UNC-51 like autophagy activating kinase 1/mammalian target of rapamycin(AMPK/mTOR/ULK1),hippocampus apoptotic factor Caspase-3 and the protein expression of autophagy markers LC-3II/Beclin-1 in the hippocampus.RESULTS AND CONCLUSION:(1)Compared with the sham operation group,rats in the ovariectomized and ovariectomized stress groups had prolonged resting time in the tail suspension test and decreased sugar-water intake and sugar-water preference in the sucrose preference test.(2)Ovary removal reduced the learning memory capacity of rats,as evidenced behaviorally by a significant increase in the number of working memory errors,the number of reference memory errors,and the completion time,and an even more pronounced increase in the above measures in the ovariectomized stress group.(3)Compared with the ovariectomized group,there was a significant reduction in the number of working memory errors,the number of reference memory errors,and the completion time in the ovariectomized stress group.(4)Compared with the sham operation group,in the ovariectomized and ovariectomized stress groups,the expression of hippocampal apoptotic factor Caspase 3 protein was significantly elevated,the expression of autophagy-related factors proteins Beclin-1 and LC3II,as well as the protein expression of AMPK and ULK1,was decreased,whereas the expression of mTOR protein was elevated.Changes in the above indicators were more significant in the ovariectomized stress group.(5)Compared with the ovariectomized stress group,in the ovariectomized stress exercise group,the protein expression of Caspase 3 was significantly decreased,the protein expression of Beclin-1 and LC3II was significantly increased,the protein expression of AMPK and ULK1 was significantly increased,and the protein expression of mTOR was significantly reduced.To conclude,4-week moderate-intensity treadmill exercise may promote cellular autophagy and reduce apoptosis through the AMPK/mTOR/ULK1 autophagy signaling pathway,thereby enhancing the learning and memory capacity of rats with ovariectomized depression

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

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 utilize single-cell RNA sequencing (scRNA-seq) to untangle the temporal expression profiles of molecules associated with congenital tooth agenesis and dental hard tissue formation during mouse molar development, and to construct a comprehensive cell atlas spanning the entire developmental period from E13.5 to P7.5, thereby providing new insights into the molecular mechanisms underlying abnormal tooth development.Methods:scRNA-seq data of murine mandibular molar tooth germs at five developmental stages (E13.5, E14.5, E16.5, P3.5, P7.5) were obtained from the GEO database (accession: GSE189381). The Seurat pipeline was employed for quality control, data normalization, dimensionality reduction, and Harmony-based batch effect correction. Cellular subpopulations were identified through uniform manifold approximation and projection dimensionality reduction, while developmental trajectories were reconstructed using Monocle for pseudotime analysis.Results:scRNA-seq analysis profiling identified 27 distinct cellular clusters, which were annotated into twelve major cell types including epithelial cells, mesenchymal cells, and endothelial cells. Msx1 exhibited a bimodal expression pattern. Pax9 reached its peak at E14.5 and then gradually decreased. Eda had a low expression level with a diffuse distribution. In contrast, Amelx and Enam were barely expressed during the embryonic stage and were activated at P3.5. Dspp was ectopically highly expressed in epithelial cells from P3.5 to P7.5, while Dmp1 was specifically upregulated in mesenchymal cells at P7.5.Conclusions:The temporal expression patterns of key regulatory genes for tooth agenesis (Msx1, Pax9, Eda), ameloblast differentiation (Amelx, Enam), and odontoblast development (Dspp, Dmp1) during mouse molar development. These findings provide a theoretical foundation and potential therapeutic targets for deciphering the molecular mechanisms underlying tooth agenesis and other developmental dental anomalies, paving the way for targeted clinical interventions.

Objective To explore the application of artificial intelligence (AI) in the standardized training of thoracic surgery residents, specifically in enhancing clinical skills and anatomical understanding through AI-assisted lung nodule identification and lung segment anatomy teaching. Methods Thoracic surgery residents undergoing standardized training at Peking Union Medical College Hospital from September 2023 to September 2024 were selected. They were randomly assigned to a trial group and a control group using a random number table. The trial group used AI-assisted three-dimensional reconstruction technology for lung nodule identification, while the control group used conventional chest CT images. After basic teaching and self-practice, the ability to identify lung nodules on the same patient CT images was evaluated, and feedback was collected through questionnaires. Results A total of 72 residents participated in the study, including 30 (41.7%) males and 42 (58.3%) females, with an average age of (24.0±3.0) years. The trial group showed significantly better overall diagnostic accuracy for lung nodules (91.9% vs. 73.3%) and lung segment identification (100.0% vs. 83.70%) compared to the control group, and the reading time was significantly shorter [ (118.5±10.5) s vs. (332.1±20.2) s, P<0.01]. Questionnaire results indicated that 94.4% of the residents had a positive attitude toward AI technology, and 91.7% believed that it improved diagnostic accuracy. Conclusion AI-assisted teaching significantly improves thoracic surgery residents’ ability to read images and clinical thinking, providing a new direction for the reform of standardized training.
