Early exercise training after stroke is a therapeutic strategy that has been paid w idespread attention. A series of studies found that early exercise training after stroke can increase expression of neurotrophic factors and maintain the integrity of the blood-brain barrier by inhibiting acute neuroinflammation and apoptosis, and reduce brain damage. This artice reviews the neuroprotective roles of early exercise training after stroke and their possible molecular mechanisms.

Background:Small bowel capsule endoscopy(SBCE)has become a first-line procedure for examining small bowel diseases. Aims:To evaluate the diagnostic value of SBCE in patients with mid-gastrointestinal bleeding(MGIB). Methods:MGIB patients who underwent SBCE from Jan. 2012 to Dec. 2014 at the Third People’s Hospital of Bengbu were enrolled. Diagnostic value of SBCE in MGIB was analyzed. Re-bleeding was followed up by outpatient visit and telephone. Results:Forty-four consecutive MGIB patients underwent SBCE procedures,the detection rate was 95. 5% and the positive rate was 65. 9% . Vascular abnormality(37. 9% ),inflammation(31. 0% )and tumor(20. 7% )were the three major etiology in SBCE positive patients. Follow-up results showed that re-bleeding rate in SBCE positive group was significantly higher than in non-positive group(41. 4% vs. 13. 3% ,P < 0. 05). Conclusions:Vascular abnormality is still the most major etiology of MGIB,meanwhile the proportions of inflammation and tumor are increasing. SBCE has a high detection rate and positive rate in initial screening of MGIB,and the risk of re-bleeding in patients with negative SBCE is low.

Objective To investigate the effect of early rehabilitation on rats' motor performance after moderate or severe experimental traumatic brain injury (TBI).Methods After adult Sprague-Dawley rats had received moderate or severe TBI,they were randomly assigned to either a 24 hour exercise group (group A),a 3-day exercise group (group B),a 7-day exercise group (group C) or a control group.Each group was composed of 8 rats.The exercise group endured forced treadmill training on an electric treadmill for 14 consecutive days initiated 24 hours,3 days or 7 days post TBI.The foot-fault and cylinder tests were performed on the 6th,12th,18th,24th and 28th day post injury.On the 28th day the rats were sacrificed and the brains were removed and frozen.The frozen coronal brain sections were stained with cresyl violet (CV) for quantitative evaluation of cortical lesion volume.Results The rats in groups B and C showed significant decreases in the percentage of left forelimb foot faults compared with the control group at the 18th,24th and28th day after injury.In addition,the rats of group C demonstrated significant decreases in the percentage of left forelimb foot-fault at the 12th day after injury.There was no significant difference between group A and the control group in terms of foot fault scores in any of the subsequent test sessions.In the cylinder test the forelimb use asymmetry scores of neither group A nor group B were significantly different from the control group.Group C showed marked locomotor asymmetry improvement at day 28 post-injury.There was no significantly different loss of hemispheric tissue between those groups.Conclusion After treadmill exercise for 14 consecutive days initiated at 3 or 7 days following moderate or severe TBI,rats' motor function improved.The cortical lesion volume was not associated with recovery of motor function.
7.Regulatory effect of microRNAs on neuroplasticity of ischemic stroke
International Journal of Cerebrovascular Diseases 2021;29(5):382-387
Ischemic stroke is one of the main causes of disability and death. Although intravenous thrombolysis and endovascular mechanical thrombectomy can achieve cerebral vascular recanalization, most patients with ischemic stroke leave serious neurological deficits due to missed treatment window. Neural plasticity is the basis of neural function repair. Recent studies have shown that microRNAs play an indispensable role in regulating neural plasticity. This article reviews the regulatory role of microRNAs on neural plasticity in ischemic stroke, in order to provide reference for the treatment of ischemic stroke.

Objective To investigate the effects and mechanisms of median nerve electrical stimulation on synaptic plasticity in ischemic stroke rats.Methods 18 healthy male SD rats were randomly divided into Sham group(n = 6),ischemic stroke group(MCAO group,n = 6)and median nerve electrical stimulation group(MNES group,n = 6).The left middle cerebral artery occlusion model of rats was established by thread plug method.Thread plug was not inserted in sham group.The median nerve electrical stimulation group was given median nerve electrical stimulation intervention on the 3rd day after modeling,and intervention on the next day.After intervention for 7 times,behavioral detection,HE staining was used to detect median nerve injury.Nissl staining was used to detect cerebral infarction volume.Western blot was used for detection of the expression level of proteins related to synaptic plasticity,and electron microscopy was performed.Results HE staining showed that median nerve electrical stimulation did not cause damage to the median nerve in stroke rats,and the median nerve membrane was intact without obvious inflammatory cells.Compared with MCAO group,the neural function,motor function and coordination of the injured forelimb in MNES group were significantly improved(P<0.01).Compared with MCAO group,cerebral infarction volume in MNES group was significantly reduced(P<0.05),the pyknosis of Nissl bodies in ischemic penumbra decreased.Compared with MCAO group,the expression levels of synaptic plastication-related proteins PSD95 and synI in the cortex of MNES group were significantly up-regulated after median nerve electrical stimulation(P<0.05),the number of synapses in the ischemic cortex increased significantly(P<0.01).Conclusion Median nerve electrical stimulation is a safe and effective therapeutic measure to improve nerve function after stroke,and its mechanism is related to promoting synaptic plasticity.
