There is increasing evidence that the gut microbiota affects the incidence and progression of central nervous system diseases via the brain-gut axis.The spinal cord is a vital important part of the central nervous system;however,the underlying association between spinal cord injury and gut interactions remains unknown.Recent studies suggest that patients with spinal cord injury frequently experience intestinal dysfunction and gut dysbiosis.Alterations in the gut microbiota can cause disruption in the intestinal barrier and trigger neurogenic inflammatory responses which may impede recovery after spinal cord injury.This review summarizes existing clinical and basic research on the relationship between the gut microbiota and spinal cord injury.Our research identified three key points.First,the gut microbiota in patients with spinal cord injury presents a key characteristic and gut dysbiosis may profoundly influence multiple organs and systems in patients with spinal cord injury.Second,following spinal cord injury,weakened intestinal peristalsis,prolonged intestinal transport time,and immune dysfunction of the intestine caused by abnormal autonomic nerve function,as well as frequent antibiotic treatment,may induce gut dysbiosis.Third,the gut microbiota and associated metabolites may act on central neurons and affect recovery after spinal cord injury;cytokines and the Toll-like receptor ligand pathways have been identified as crucial mechanisms in the communication between the gut microbiota and central nervous system.Fecal microbiota transplantation,probiotics,dietary interventions,and other therapies have been shown to serve a neuroprotective role in spinal cord injury by modulating the gut microbiota.Therapies targeting the gut microbiota or associated metabolites are a promising approach to promote functional recovery and improve the complications of spinal cord injury. 展开更多

Alzheimer’s disease is a common neurodegenerative disorder defined by decreased reasoning abilities,memory loss,and cognitive deterioration.The presence of the blood-brain barrier presents a major obstacle to the development of effective drug therapies for Alzheimer’s disease.The use of ultrasound as a novel physical modulation approach has garnered widespread attention in recent years.As a safe and feasible therapeutic and drug-delivery method,ultrasound has shown promise in improving cognitive deficits.This article provides a summary of the application of ultrasound technology for treating Alzheimer’s disease over the past 5 years,including standalone ultrasound treatment,ultrasound combined with microbubbles or drug therapy,and magnetic resonance imaging-guided focused ultrasound therapy.Emphasis is placed on the benefits of introducing these treatment methods and their potential mechanisms.We found that several ultrasound methods can open the blood-brain barrier and effectively alleviate amyloid-βplaque deposition.We believe that ultrasound is an effective therapy for Alzheimer’s disease,and this review provides a theoretical basis for future ultrasound treatment methods. 展开更多
