BACKGROUND:Pyroptosis participate in the degradation of the extracellular matrix of chondrocytes,synovial inflammation and pain,and plays an important role in the prevention and treatment of osteoarthritis.In addition,exercise can inhibit the occurrence of pyroptosis to regulate the progression of osteoarthritis,which has become a research hot spot in the prevention and treatment of osteoarthritis. OBJECTIVE:To summarize the regulatory role of pyroptosis in osteoarthritis and the mechanism of exercise-mediated pyroptosis in osteoarthritis. METHODS:PubMed and CNKI databases were searched during 1992 to 2024 with the keywords"pyroptosis,osteoarthritis,chondrocyte pyroptosis,synovial cell pyroptosis,exercise"in English and Chinese,respectively.Finally,71 relevant articles were selected according to the inclusion and exclusion criteria. RESULTS AND CONCLUSION:(1)Osteoarthritis is a chronic degenerative joint disease characterized by the breakdown of cartilage extracellular matrix,synovial inflammation,and subchondral bone remodeling.This condition often leads to organic lesions,bone pain,and functional impairment.(2)Pyroptosis,a distinct programmed cell death mechanism,involves cell lysis and the release of inflammatory cytokines,triggering a robust inflammatory response,and is closely related to the development of osteoarthritis.Pyroptosis can result in the release of numerous inflammatory factors,thereby activate the nuclear factor kappa-B transcription and increase pyroptosis protein production,and in turn exacerbate the occurrence and development of osteoarthritis.Therefore,pyroptosis can be a new direction for the prevention and treatment of osteoarthritis.(3)Exercise has been shown to down-regulate the pyroptosis protein signaling pathway and inhibit the expression of related inflammatory factors,thereby playing a pivotal role in osteoarthritis prevention and treatment.Aerobic and anaerobic exercises can delay the pathological process of osteoarthritis by inhibiting the occurrence of pyroptosis.Moderate-intensity aerobic exercise is most effective in improving osteoarthritis by inhibiting pyroptosis signaling pathways,while anaerobic exercise can have beneficial effects on osteoarthritis by improving muscle mass.

BackgroundGraduate students frequently face life events， many of which may adversely affect their mental well-being. However， the interaction between life events and the development of depression， anxiety， and somatic symptoms remains unclear. ObjectiveTo explore the relationship between life events and the development of depressive， anxiety and somatic symptoms in graduate students， thereby informing prevention strategies for these conditions. MethodsA sample of 6 722 newly enrolled graduate students at a comprehensive university in Southwest China from September to November 2018 was selected. The assessment was conducted using the Adolescent Self-rating Life Events Checklist （ASLEC）， the 7-item Generalized Anxiety Disorder scale-7 item （GAD-7）， the Patient Health Questionnaire Depression Scale-9 item （PHQ-9）， and the Patient Health Questionnaire-15 （PHQ-15）. Network analysis was implemented by using the bootnet and qgraph packages in the R software （version 4.2.3）， with centrality indices calculated to identify core and bridge symptoms within the network. ResultsThe study encompassed a total of 6 171 graduate students， representing 91.80% of the target population. The prevalence rates of anxiety， depressive， and somatic symptoms among graduate students were 12.59% （777/6 171）， 16.63% （1 026/6 171）， and 27.66% （1 707/6 171）， respectively. Network analysis revealed that 'academic stress' was the core symptom with the highest strength and expected influence （both values=1.207）， while 'feeling down， depressed， or hopeless' was the bridge symptom with the highest bridge strength and bridge expected influence （both values=0.454）. There was no significant difference in global network strength and edge weight between women and men （P>0.05）. ConclusionAcademic stress， emerging as the core symptom， assumes a dominant position within the symptom network and exhibits strong interactions with other negative affective states. There was no gender difference in the network structure.

Objective:Ménière's disease（MD） is a common disorder of the inner ear. The fluctuating clinical symptoms and the absence of gold standards for diagnosis have posed serious problems for clinical diagnosis and treatment over the years. With the development of science and technology, artificial intelligence （AI） has been widely used in the field of medicine, and the potential of AI application to MD is demonstrated. The purpose of this review is to outline the use of AI in MD. Initially, specific instances where AI aids in differentiating MD from other causes of vertigo are presented. Furthermore, the role of AI in the evaluation of Endolymphatic Hydrops （EH）, particularly through imaging and biochemical assays, is highlighted due to its correlation with MD. Additionally, the effectiveness of AI in managing MD patients and forecasting disease progression is examined. In conclusion, the prevalent challenges hindering the clinical integration of AI in MD treatment are discussed, alongside potential strategies to surmount these barriers.
