Basic mechanisms of peripheral nerve injury and treatment via electrical stimulation

Previous studies on the mechanisms of peripheral nerve injury(PNI)have mainly focused on the pathophysiological changes within a single injury site.However,recent studies have indicated that within the central nervous system,PNI can lead to changes in both injury sites and target organs at the cellular and molecular levels.Therefore,the basic mechanisms of PNI have not been comprehensively understood.Although electrical stimulation was found to promote axonal regeneration and functional rehabilitation after PNI,as well as to alleviate neuropathic pain,the specific mechanisms of successful PNI treatment are unclear.We summarize and discuss the basic mechanisms of PNI and of treatment via electrical stimulation.After PNI,activity in the central nervous system(spinal cord)is altered,which can limit regeneration of the damaged nerve.For example,cell apoptosis and synaptic stripping in the anterior horn of the spinal cord can reduce the speed of nerve regeneration.The pathological changes in the posterior horn of the spinal cord can modulate sensory abnormalities after PNI.This can be observed in cases of ectopic discharge of the dorsal root ganglion leading to increased pain signal transmission.The injured site of the peripheral nerve is also an important factor affecting post-PNI repair.After PNI,the proximal end of the injured site sends out axial buds to innervate both the skin and muscle at the injury site.A slow speed of axon regeneration leads to low nerve regeneration.Therefore,it can take a long time for the proximal nerve to reinnervate the skin and muscle at the injured site.From the perspective of target organs,long-term denervation can cause atrophy of the corresponding skeletal muscle,which leads to abnormal sensory perception and hyperalgesia,and finally,the loss of target organ function.The mechanisms underlying the use of electrical stimulation to treat PNI include the inhibition of synaptic stripping,addressing the excessive excitability of the dorsal root ganglion,alleviating neuropathic pain,improving neurological function,and accelerating nerve regeneration.Electrical stimulation of target organs can reduce the atrophy of denervated skeletal muscle and promote the recovery of sensory function.Findings from the included studies confirm that after PNI,a series of physiological and pathological changes occur in the spinal cord,injury site,and target organs,leading to dysfunction.Electrical stimulation may address the pathophysiological changes mentioned above,thus promoting nerve regeneration and ameliorating dysfunction.

Role of mitochondrial quality control in exercise-induced health adaptation

Long-term endurance training or physical activity has been confirmed not only to improve physical performance, but to bring about an obvious beneficial effect on human health; however, the mechanism of this effect is not clear. The most studied health adaptations in skeletal muscle response to endurance exercise are increased muscle glycogen level and insulin sensitivity, fiber type transformation toward oxidative myofibers, and increased mitochondrial content/function. Mitochondria are dynamic organelles in eukaryotic cells critical in physical performance and disease occurrence. The mitochondrial life cycle spans biogenesis, maintenance, and clearance. Exercise training may promote each of these processes and confer positive impacts on skeletal muscle contractile and metabolic functions. This review focused on the regulation of these processes by endurance exercise and discussed its potential benefits in health and disease. We presented evidence suggesting that exercise training potentiates not only the biogenesis of mitochondria but also the removal of old and unhealthy mitochondria through mitochondrial quality control.

An ultrasound-guided percutaneous electrical nerve stimulation regimen devised using finite element modeling promotes functional recovery after median nerve transection

Percutaneous electrical nerve stimulation of an injured nerve can promote and accelerate peripheral nerve regeneration and improve function.When performing acupuncture and moxibustion,locating the injured nerve using ultrasound before percutaneous nerve stimulation can help prevent further injury to an already injured nerve.However,stimulation parameters have not been standardized.In this study,we constructed a multi-layer human forearm model using finite element modeling.Taking current density and activated function as optimization indicators,the optimal percutaneous nerve stimulation parameters were established.The optimal parameters were parallel placement located 3 cm apart with the injury site at the midpoint between the needles.To validate the efficacy of this regimen,we performed a randomized controlled trial in 23 patients with median nerve transection who underwent neurorrhaphy.Patients who received conventional rehabilitation combined with percutaneous electrical nerve stimulation experienced greater improvement in sensory function,motor function,and grip strength than those who received conventional rehabilitation combined with transcutaneous electrical nerve stimulation.These findings suggest that the percutaneous electrical nerve stimulation regimen established in this study can improve global median nerve function in patients with median nerve transection.

Parkin promotes proteasomal degradation of p62： implication of selective vulnerability of neuronal cells in the pathogenesis of Parkinson＇s disease

Mutations or inactivation of parkin, an E3 ubiquitin ligase, are associated with familial form or sporadic Parkinson＇s disease （PD）, respectively, which manifested with the selective vulnerability of neuronal ceils in substantia nigra （SN） and striatum （STR） regions. However, the underlying molecular mechanism linking parkin with the etiology of PD remains elusive. Here we report that p62, a critical regulator for protein quality control, inclusion body formation, selective autophagy and diverse signaling pathways, is a new substrate of parkin. P62 levels were increased in the SN and STR regions, but not in other brain regions in parkin knockout mice. Parkin directly interacts with and ubiquitinates p62 at the K13 to promote proteasomal degradation of p62 even in the absence of ATG5. Pathogenic mutations, knockdown of parkin or mutation of p62 at K13 prevented the degradation of p62. We further showed that parkin deficiency mice have pronounced loss of tyrosine hydroxylase positive neurons and have worse performance in motor test when treated with 6-hydroxydopamine hydrochloride in aged mice. These results suggest that, in addition to their critical role in regulating autophagy, p62 are subjected to parkin mediated proteasomal degradation and implicate that the dysregulation of parkin/p62 axis may involve in the selective vulnerability of neuronal cells during the onset of PD pathogenesis.

Effects of silent myocardial ischemia on functional fitness and physical independence in 60–79-year-old adults

Objective:We examined the effect of silent myocardial ischemia(SMI)on functional fitness levels and physical independence in 60–79-year-old individuals.Methods:We conducted a cross-sectional study with 716 older adults and used an electrocardiograph and an ambulatory electrocardiogram to diagnose those with SMI.Physical independence was assessed using the Composite Physical Function scale,whereas physical fitness was assessed using the Senior Fitness Test battery.Results:The 60-79-year-old females and males with SMI were more likely to have lower scores for lower and upper body strength,agility/dynamic balance,and aerobic endurance(p<0.05)than those without SMI.The scores for lower and upper body flexibility in all age groups for both genders were not significant(p>0.05).Binary logistic regression analysis revealed that old adults with SMI had a higher risk of losing physical independence later in life than those without SMI(p<0.05).Conclusion:This study showed that individuals with SMI have lower fitness levels and increased risk of losing physical independence than those without SMI.

Acute exercise in ozone-polluted air induces apoptosis in rat quadriceps femoris muscle cells via mitochondrial pathway

Ozone(O_(3))pollution can decrease sport performance and induce respiratory toxicity,but relatively few studies have investigated its effects on skeletal muscles.We randomly assigned rats to the following groups based on a 2×4 two-factor factorial design:Air+0,Air+10,Air+15,and Air+20,O_(3)+0,O_(3)+10,O_(3)+15,and O_(3)+20.The rats in the+0 groups rested,whereas those in the+10,+15,and+20 groups ran on a treadmill(in clean air for Air groups and in air polluted with 0.14 parts per million[ppm]O_(3)for O_(3)groups)at speeds of+10,+15,and+20 m/min,respectively,for 1 h.Thereafter,key enzyme activities involving the tricarboxylic acid cycle,oxidative phosphorylation,adenosine triphosphate(ATP)content,histopathological changes,oxidative stress,inflammation factors,and apoptosis were assessed in the rat quadriceps femoris samples.Ozone reduced key enzyme activities and ATP contents in the quadriceps femoris regardless of whether the rats exercised.Pathological changes,inflammatory factors,oxidative stress,and mitochondria-dependent apoptosis were only evident under conditions of exercise combined with ozone and increasingly worsened as exercise intensity increased.These findings suggested that acute exercise under ozone exposure could induce damage to the quadriceps femoris,which would negatively affect sport performance.Ozone-induced disrupted energy metabolism might be an early event that becomes more critical as exercise intensity increases.Therefore,care should be taken when exercising in polluted air,even when ozone pollution is mild.
