Atrial fibrillation (AF) is the most common arrhythmia in clinical practice. It has a high prevalence and poor prognosis. The application of antiarrhythmic drugs and even surgery cannot completely treat the disease, and there are many sequelae. AF can be classified into the category of "palpitation" in Chinese medicine according to its symptoms. Acupuncture has a significant effect on AF. The authors find that an important mechanism of acupuncture in AF treatment is to regulate the cardiac vagus nerve. Therefore, this article intends to review the distribution and function of vagus nerve in the heart, the application and the regulatroy effect for the treatment of AF.

OBJECTIVE: To investigate the relationship between physical activity and genetic risk and their combined effects on the risk of developing chronic obstructive pulmonary disease. METHODS: This prospective cohort study included 318,085 biobank participants from the UK. Physical activity was assessed using the short form of the International Physical Activity Questionnaire. The participants were stratified into low-, intermediate-, and high-genetic-risk groups based on their polygenic risk scores. Multivariate Cox regression models and multiplicative interaction analyses were used. RESULTS: During a median follow-up period of 13 years, 9,209 participants were diagnosed with chronic obstructive pulmonary disease. For low genetic risk, compared to low physical activity, the hazard ratios ( HRs) for moderate and high physical activity were 0.853 (95% confidence interval [ CI]: 0.748-0.972) and 0.831 (95% CI: 0.727-0.950), respectively. For intermediate genetic risk, the HRs were 0.829 (95% CI: 0.758-0.905) and 0.835 (95% CI: 0.764-0.914), respectively. For participants with high genetic risk, the HRs were 0.809 (95% CI: 0.746-0.877) and 0.818 (95% CI: 0.754-0.888), respectively. A significant interaction was observed between genetic risk and physical activity. CONCLUSION Moderate or high levels of physical activity were associated with a lower risk of developing chronic obstructive pulmonary disease across all genetic risk groups, highlighting the need to tailor activity interventions for genetically susceptible individuals.

Skeletal muscle is the basis of body movement,and it is an important support to maintain daily life activities.In recent years,the incidence of skeletal muscle atrophy has been increasing year by year,which has seriously affected the lives of individuals and brought a certain burden to the family and society,how to prevent and control skeletal muscle atrophy has attracted extensive attention from various disciplines.Exercise as a safe,easy-to-operate,and inexpen-sive treatment has been widely used in the treatment of many chronic diseases.To explore the role of exercise training in the treatment of muscular dystrophy-like diseases,we review the key role of exercise in the reconstruction process of skele-tal muscle atrophy from the molecular mechanism of skeletal muscle atrophy and regeneration,thus providing new ideas and insights for the clinical treatment of muscle atrophy.

In recent years,there has been a significant rise in the incidence of peripheral nerve injury(PNI),highlighting the urgent need for effective treatment strategies.The inflammation and pain hypersensitivity associated with PNI greatly diminish patients'quality of life.Although there are promising treatment approaches for nerve injury,the com-plex pathological mechanisms underlying neuropathic pain caused by PNI present significant challenges for clinical manage-ment.Extensive research has established that the development of neuropathic pain is closely linked to nerve conduction and related signaling molecules.Among these,P2X4 receptor(P2X4R),an ATP-dependent ion channel,is involved in nerve signal transmission and associated pathways-plays a crucial role in the progression of neuropathic pain.This article offers a comprehensive overview of the function and distribution of P2X4R,investigates its pathological mechanisms in PNI-induced neuropathic pain,and elucidates its relationship with peripheral neuropathic pain disorders.Through this explo-ration,we aim to provide valuable insights that could inform the development of novel clinical strategies for pain management.

Objective:To assess the efficacy of parent training (PT) on attention deficit hyperactivity disorder (ADHD) symptoms, behavioral problems, and parenting stress in child with ADHD or ADHD symptoms.Methods:Randomized controlled trials of the effect of PT on ADHD symptoms in Chinese children with ADHD or ADHD symptoms were collected by PsychINFO, PubMed, EMBASE, Web of science, Scopus, China National Knowledge database, WanFang database, the China Science and Technology Journal Database and the China Biology Medicine disc. The quality of the included studies was evaluated by version 2 of the Cochrane tool for assessing risk of bias in randomized trial. Forest plots were drawn using Review Manager 5.4.1, sensitivity analyses of results were performed using Stata 18.0 to assess the stability of the results, and publication bias was assessed using funnel plots and Egger's test.Results:A total of 10 studies containing 571 subjects in the experimental group and 562 subjects in the control group met the inclusion exclusion criteria. Significant differences were observed in various measures, including overall ADHD symptoms (MD=-2.43, 95% CI: -3.95--0.91), inattention (MD=-1.10, 95% CI: -1.94--0.26), hyperactivity/impulsivity (SMD=-0.58, 95% CI: -0.87--0.28), overall conduct problems (SMD=-0.80, 95% CI: -1.05--0.55), conduct problem (SMD=-1.34, 95% CI: -2.31--0.37), learning problem (SMD=-0.81, 95% CI: -1.40--0.23), impulsivity/hyperactivity (SMD=-0.53, 95% CI: -0.78--0.29), hyperactivity index (SMD=-1.27, 95% CI: -1.99--0.55), parenting stress index (SMD=-0.69, 95% CI: -1.12--0.26), difficult child (MD=-1.96, 95% CI: -3.44--0.48), dysfunctional interaction (MD=-3.10, 95% CI: -4.43--1.78), and parenting distress (MD=-3.35, 95% CI: -4.59--2.12)(all P<0.05). However, no significant differences were observed in oppositional-defiant disorder, anxiety, or somatic problem. Conclusions:The initial findings suggested that PT was effective for Chinese children with ADHD or ADHD symptoms.The addition of PT appeared to improve core symptoms of ADHD (inattention and hyperactivity/impulsivity), conduct problems, and parental stress more effectively than routine care alone.

Skeletal muscle wasting refers to a loss of skeletal muscle mass and function.Mitochondrial quality control(MQC)is the basis by which normal physiological mitochondrial function is maintained and mainly involves the regulation of mitochondrial biogenesis,mitochondrial dynamics(fission/fusion),and mitophagy.MQC maintains muscle homeostasis by regulating the relative stability of mitochondrial shape,quantity,and quality.As an economical and effective treatment for muscular atrophy,exercise interventions are widely used,but the relationship between exercise intervention and MQC is not clear.This paper discusses the role of mitochondrial biogenesis,mitochondrial dynamics,and mitophagy in skeletal muscle atrophy and related molecular targets.We thoroughly analyze the mechanisms by which MQC-mediated exercise can improve the skeletal muscle atrophy caused by aging,disuse,and cancer cachexia in order to provide theoretical guidance for intervention.

Osteoarthritis （OA） is characterized by articular cartilage degeneration， synovial hyperplasia， hyperosteogeny， and narrowing of joint space， which can be caused by trauma， inflammation， and other factors. With the increasing global population aging， the incidence of OA is rising year by year， making it a major public health problem that urgently needs to be addressed. Exploring effective treatment schemes is particularly important. The pathogenesis of OA is complex， including oxidative stress， autophagy， and apoptosis. Recent studies have found that ferroptosis， a new type of cell death， is also an important pathogenic factor in OA， characterized by a series of complex changes such as iron ion accumulation， glutathione （GSH） depletion， and mitochondrial dysfunction. Research shows that inhibiting ferroptosis in chondrocytes can promote chondrocyte proliferation， delay extracellular matrix （ECM） degradation， and reduce synovial hyperplasia and inflammation. Targeting ferroptosis is a new direction in the treatment of OA. OA treatment includes intra-articular injections of steroids or hyaluronic acid and artificial joint replacement， but there are limitations. Traditional Chinese medicine （TCM） has been widely used in the treatment of various diseases because of its low cost， low drug resistance， and few side effects. Cell and animal experiments have further confirmed that TCM can intervene in the treatment of OA with ferroptosis from multiple targets， multiple levels， and aspects， but the mechanism of its treatment of OA based on ferroptosis has not been clarified. This paper discussed iron metabolism， lipid peroxidation， cysteine/glutamate transporter system Xc^- （system Xc^-）/GSH/glutathione peroxidase 4 （GPX4） pathway， nicotinamide adenine dinucleotide phosphate（NADPH）/ferroptosis suppressor protein 1 （FSP1）/coenzyme Q₁₀ （CoQ₁₀） pathway， tumor protein p53 in OA， and related molecular targets of Chinese medicine monomers and compounds on ferroptosis inhibition. Their potential therapeutic mechanisms were further analyzed to provide theoretical guidance for the treatment of OA by TCM and useful reference for the research and development of related drugs.
