The M1/M2 phenotypic shift of microglia after spinal cord injury plays an important role in the regulation of neuroinflammation during the secondary injury phase of spinal cord injury.Regulation of shifting microglia ...The M1/M2 phenotypic shift of microglia after spinal cord injury plays an important role in the regulation of neuroinflammation during the secondary injury phase of spinal cord injury.Regulation of shifting microglia polarization from M1(neurotoxic and proinflammatory type)to M2(neuroprotective and anti-inflammatory type)after spinal cord injury appears to be crucial.Tryptanthrin possesses an anti-inflammatory biological function.However,its roles and the underlying molecular mechanisms in spinal cord injury remain unknown.In this study,we found that tryptanthrin inhibited microglia-derived inflammation by promoting polarization to the M2 phenotype in vitro.Tryptanthrin promoted M2 polarization through inactivating the cGAS/STING/NF-κB pathway.Additionally,we found that targeting the cGAS/STING/NF-κB pathway with tryptanthrin shifted microglia from the M1 to M2 phenotype after spinal cord injury,inhibited neuronal loss,and promoted tissue repair and functional recovery in a mouse model of spinal cord injury.Finally,using a conditional co-culture system,we found that microglia treated with tryptanthrin suppressed endoplasmic reticulum stress-related neuronal apoptosis.Taken together,these results suggest that by targeting the cGAS/STING/NF-κB axis,tryptanthrin attenuates microglia-derived neuroinflammation and promotes functional recovery after spinal cord injury through shifting microglia polarization to the M2 phenotype.展开更多

文摘Flavonoids have been reported to have therapeutic potential for spinal cord injury.Hawthorn leaves have abundant content and species of total flavonoids,and studies of the effects of the total flavonoids of hawthorn leaves on spinal cord injury have not been published in or outside China.Therefore,Sprague-Dawley rats were used to establish a spinal cord injury model by Allen's method.Rats were intraperitoneally injected with 0.2 m L of different concentrations of total flavonoids of hawthorn leaves(5,10,and 20 mg/kg)after spinal cord injury.Injections were administered once every 6 hours,three times a day,for 14 days.After treatment with various concentrations of total flavonoids of hawthorn leaves,the Basso,Beattie,and Bresnahan scores and histological staining indicated decreases in the lesion cavity and number of apoptotic cells of the injured spinal cord tissue;the morphological arrangement of the myelin sheath and nerve cells tended to be regular;and the Nissl bodies in neurons increased.The Basso,Beattie,and Bresnahan scores of treated spinal cord injury rats were increased.Western blot assays showed that the expression levels of pro-apoptotic Bax and cleaved caspase-3 were decreased,but the expression level of the anti-apoptotic Bcl-2 protein was increased.The improvement of the above physiological indicators showed a dose-dependent relationship with the concentration of total flavonoids of hawthorn leaves.The above findings confirm that total flavonoids of hawthorn leaves can reduce apoptosis and exert neuroprotective effects to promote the recovery of the motor function of rats with spinal cord injury.This study was approved by the Ethics Committee of the Guangxi Medical University of China(approval No.201810042)in October 2018.

文摘Promotion of new blood vessel formation is a new strategy for treating ischemic stroke.Non-coding miRNAs have been recently considered potential therapeutic targets for ischemic stroke.miR-181b has been shown to promote angiogenesis in hypoxia and traumatic brain injury model,while its effect on ischemic stroke remains elusive.In this study,we found that overexpression of miR-181b in brain microvascular endothelial cells subjected to oxygen-glucose deprivation in vitro restored cell prolife ration and enhanced angiogenesis.In rat models of focal cerebral ischemia,ove rexpression of miR-181b reduced infarction volume,promoted angiogenesis in ischemic penumbra,and improved neurological function.We further investigated the molecular mechanism by which miR-181b participates in angiogenesis after ischemic stroke and found that miR-181b directly bound to the 3’-UTR of phosphatase and tensin homolog(PTEN) mRNA to induce PTEN downregulation,leading to activation of the protein kinase B(Akt) pathway,upregulated expression of vascular endothelial growth facto rs,down-regulated expression of endostatin,and promoted angiogenesis.Taken togethe r,these results indicate that exogenous miR-181b exhibits neuroprotective effects on ischemic stro ke through activating the PTEN/Akt signal pathway and promoting angiogenesis.
文摘Objective: To evaluate the therapeutic effect of infantile massage on intestinal adhesions after abdominal operation and its influence on the recovery of intestinal function. Methods: 60 children with intestinal adhesions after abdominal operation in our hospital from October 2019 to June 2020 were selected and divided into two groups according to different treatment schemes, study group (n = 30) and control group (n = 30). The former was given infantile massage, while the latter was not treated after operation. The incidence of postoperative intestinal adhesion was compared between the two groups, and the results of anal exhaust, defecation time and abdominal pain disappearance time of the two groups were compared. Results: the incidence of postoperative intestinal adhesion in the study group was lower than that in the control group (P < 0.05);compared with the control group, the average time of anal exhaust and defecation, appetite recovery and abdominal pain disappearance in the study group was shorter than that in the control group (P < 0.05). Conclusion: infantile massage after abdominal operation can reduce the incidence of postoperative intestinal adhesion, shorten the time of anal exhaust and defecation, appetite recovery and abdominal pain disappearance, and promote the rapid recovery of intestinal function.

文摘Schwann cell transplantation is considered one of the most promising cell-based therapy to repair injured spinal cord due to its unique growth-promoting and myelin-forming properties.A the Food and Drug Administration-approved Phase I clinical trial has been conducted to evaluate the safety of transplanted human autologous Schwann cells to treat patients with spinal cord injury.A major challenge for Schwann cell transplantation is that grafted Schwann cells are confined within the lesion cavity,and they do not migrate into the host environment due to the inhibitory barrier formed by injury-induced glial scar,thus limiting axonal reentry into the host spinal cord.Here we introduce a combinatorial strategy by suppressing the inhibitory extracellular environment with injection of lentivirus-mediated transfection of chondroitinase ABC gene at the rostral and caudal borders of the lesion site and simultaneously leveraging the repair capacity of transplanted Schwann cells in adult rats following a mid-thoracic contusive spinal cord injury.We report that when the glial scar was degraded by chondroitinase ABC at the rostral and caudal lesion borders,Schwann cells migrated for considerable distances in both rostral and caudal directions.Such Schwann cell migration led to enhanced axonal regrowth,including the serotonergic and dopaminergic axons originating from supraspinal regions,and promoted recovery of locomotor and urinary bladder functions.Importantly,the Schwann cell survival and axonal regrowth persisted up to 6 months after the injury,even when treatment was delayed for 3 months to mimic chronic spinal cord injury.These findings collectively show promising evidence for a combinatorial strategy with chondroitinase ABC and Schwann cells in promoting remodeling and recovery of function following spinal cord injury.

文摘The M1/M2 phenotypic shift of microglia after spinal cord injury plays an important role in the regulation of neuroinflammation during the secondary injury phase of spinal cord injury.Regulation of shifting microglia polarization from M1(neurotoxic and proinflammatory type)to M2(neuroprotective and anti-inflammatory type)after spinal cord injury appears to be crucial.Tryptanthrin possesses an anti-inflammatory biological function.However,its roles and the underlying molecular mechanisms in spinal cord injury remain unknown.In this study,we found that tryptanthrin inhibited microglia-derived inflammation by promoting polarization to the M2 phenotype in vitro.Tryptanthrin promoted M2 polarization through inactivating the cGAS/STING/NF-κB pathway.Additionally,we found that targeting the cGAS/STING/NF-κB pathway with tryptanthrin shifted microglia from the M1 to M2 phenotype after spinal cord injury,inhibited neuronal loss,and promoted tissue repair and functional recovery in a mouse model of spinal cord injury.Finally,using a conditional co-culture system,we found that microglia treated with tryptanthrin suppressed endoplasmic reticulum stress-related neuronal apoptosis.Taken together,these results suggest that by targeting the cGAS/STING/NF-κB axis,tryptanthrin attenuates microglia-derived neuroinflammation and promotes functional recovery after spinal cord injury through shifting microglia polarization to the M2 phenotype.

文摘The presence of endogenous neural stem/progenitor cells in the adult mammalian brain suggests that the central nervous system can be repaired and regenerated after injury.However,whether it is possible to stimulate neurogenesis and reconstruct cortical layers II to VI in non-neurogenic regions,such as the cortex,remains unknown.In this study,we implanted a hyaluronic acid collagen gel loaded with basic fibroblast growth factor into the motor cortex immediately following traumatic injury.Our findings reveal that this gel effectively stimulated the proliferation and migration of endogenous neural stem/progenitor cells,as well as their differentiation into mature and functionally integrated neurons.Importantly,these new neurons reconstructed the architecture of cortical layers II to VI,integrated into the existing neural circuitry,and ultimately led to improved brain function.These findings offer novel insight into potential clinical treatments for traumatic cerebral cortex injuries.
文摘Spinal cord injury(SCI) often results in permanent dysfunction of locomotion,sensation,and autonomic regulation,imposing a substantial burden on both individuals and society(Anjum et al.,2020).SCI has a complex pathophysiology:an initial primary injury(mechanical trauma,axonal disruption,and hemorrhage) is followed by a progressive secondary injury cascade that involves ischemia,neuronal loss,and inflammation.Given the challenges in achieving regeneration of the injured spinal cord,neuroprotection has been at the forefront of clinical research.
文摘BACKGROUND Total knee arthroplasty(TKA)aims to restore motion and alleviate pain,enabling patients to return to daily activities.Despite advances in implants,surgery,and perioperative care,patient dissatisfaction rates remain significant.AIM To determine whether ankle symptoms are associated with inferior results of functional recovery of the knee following TKA.METHODS This prospective study included all patients with advanced knee osteoarthritis who underwent a primary unilateral TKA between August 2019 and December 2019 with data documented by the treating surgeon and outpatient physical therapists.Patients were categorized based on ankle symptoms using the Ame-rican Orthopaedic Foot and Ankle Society(AOFAS)score:(1)Group 1(AOFAS≤85,n=30);and(2)Group 2(AOFAS>85,n=49).Active range of motion(ROM),the Knee Injury and Osteoarthritis Outcome Score(KOOS),and the visual ana-logue scale(VAS)were compared between two groups.RESULTS Postoperative KOOS,ROM,and VAS significantly improved in both groups(P<0.001).However,at three months,KOOS(P=0.02)and extension motion(P=0.01)improvements were significantly greater in group 2.CONCLUSION These findings suggest that preoperative ankle symptoms may negatively impact early knee functional recovery,particularly in KOOS scores and extension motion.
文摘Objective:To investigate the effects of performance-linked early rehabilitation management model on the recovery of neurological function,motor function and activities of daily living in patients after intracerebral hemorrhage surgery.Methods:A randomized controlled trial design was adopted.A total of 120 patients after cerebral hemorrhage surgery admitted to our hospital from June 2023 to June 2024 were selected as the research subjects and were randomly divided into the experimental group and the control group,with 60 cases in each group according to the random number table method.The control group received routine postoperative care and rehabilitation guidance in neurosurgery,while the experimental group implemented an efficacy linkage early rehabilitation management model on the basis of routine care.Before the intervention,4 weeks after the intervention,and 12 weeks after the intervention,the National Institutes of Health Stroke Scale(NIHSS),the Fugl-Meyer Assessment of Motor Function(FMA),and the Barthel Index(BI)were used to assess the degree of neurological deficits,motor function,and activities of daily living in patients,respectively.Results:After 4 weeks and 12 weeks of intervention,the NIHSS scores of the experimental group[(8.5±2.1)points,(5.2±1.8)points]were significantly lower than those of the control group[(10.8±2.4)points,(7.9±2.2)points](P<0.01);FMA scores[(58.4±10.2)points,(78.6±12.4)points]and BI scores[(55.3±11.5)points,(72.8±13.2)points]were significantly higher than those of the control group[(45.2±9.8)points,(62.3±11.7)points;(42.1±10.6)points,(58.4±12.5)points](P<0.01).Conclusion:The performance-linked early rehabilitation management model can effectively promote the recovery of neurological and motor functions in patients after cerebral hemorrhage surgery and significantly improve their ability to take care of themselves in daily living.It is an efficient rehabilitation management strategy.

文摘Spontaneous recovery frequently proves maladaptive or insufficient because the plasticity of the injured adult mammalian central nervous system is limited.This limited plasticity serves as a primary barrier to functional recovery after brain injury.Neuromodulation technologies represent one of the fastest-growing fields in medicine.These techniques utilize electricity,magnetism,sound,and light to restore or optimize brain functions by promoting reorganization or long-term changes that support functional recovery in patients with brain injury.Therefore,this review aims to provide a comprehensive overview of the effects and underlying mechanisms of neuromodulation technologies in supporting motor function recovery after brain injury.Many of these technologies are widely used in clinical practice and show significant improvements in motor function across various types of brain injury.However,studies report negative findings,potentially due to variations in stimulation protocols,differences in observation periods,and the severity of functional impairments among participants across different clinical trials.Additionally,we observed that different neuromodulation techniques share remarkably similar mechanisms,including promoting neuroplasticity,enhancing neurotrophic factor release,improving cerebral blood flow,suppressing neuroinflammation,and providing neuroprotection.Finally,considering the advantages and disadvantages of various neuromodulation techniques,we propose that future development should focus on closed-loop neural circuit stimulation,personalized treatment,interdisciplinary collaboration,and precision stimulation.
