[Objective]To investigate the protective effects of rhEPO on neuromotor function and apoptosis of neural cell,after it was peritoneally injected at different time in rats with traumatic spinal cord injury(SCI).[Method]A total of 48 adult male Sprague-Dawley rats weighting 270 ?10 g were randomly divided into four groups.Rats in normal group(n=6)and sham group(n=6)underwent laminectomy producure only.In control group,rats(n=18)received normal saline epidurally at 1,6 and 24 hours after injury.Treatment group(n=18)received 5000 iu/kg body weight of recombinant humane erythropoietin administered epidurally at 1,6 and 24 hours after injury.SCI was induced with 70g/cm impact according to the improved Allen method.Behavioral evaluation of the rats was made 48 hours after trauma using the Basso,Beattie,and Bresnahan(BBB)scoring system and Rivlin's tiltboard experiment.Injured spinal cord tissue cell apoptosis was examined by the terminal deoxynucleotidal transferase-mediated dUTP-biotin nick end abeling(TUNEL)reaction at 48 hour.Fasl and Caspase-3 expression was determined by immunohistochemical analysis at 48 hours after injury.The results were observed by light microscope and analyzed by SPSS statistics software.[Result]Compared to the control group,neuromotor function was significantly improved at 1,6,and 24 hours after injury in the experiment group.The indexes of neural cell decreased significantly(P

Objective To evaluate the clinical effect of endovascular embolization for traumatic carotid cavernous fistula (TCCF).Methods In 20 patients with TCCF,10 were treated with the detachable balloon embolization,4 were treated with the detachable balloon embolization and coils,2 were treated with coils alone,3 were treated with coils and Onyx,and 1 was treated with covered stenting.Two of them were embolized again because of leaking balloon.Results Eighteen of the 20 patients were embolizeded successfully once,2 were embolizeded successfully twice.The patency rate of internal carotid artery was 100％.No operation-related complications occurred.Conclusions Endovascular embolization is a simply,safe and reliable method of curative effect for the treatment of TCCF.

Objective To study the length changes of the inferior glenohumeral ligament(IGHL) during shoulder abduction with MRI and 3D software.Methods Fourteen right shoulder joints of 14 healthy volunteers were evaluated in 7 isometric abduction positions(0?,30?,60?,90?,120?,150?,and 180?) using MRI scanning.3D shoulder models were reconstructed and the attachment points of the ligaments were located.The shortest ligament lengths were calculated between each origin and insertion in 3D space for each abduction position.Results During shoulder abduction,the 3D distance of AIGHL was found to elongate and attained the maximal length at 120? abduction(54.5 mm?3.0 mm)(P

ObjectiveTo investigate the expression of miR-155 and miR-146a in peripheral blood mononuclear cells (PBMC) and plasma of rheumatoid arthritis (RA) patients.MethodsPBMC and plasma were separated from the peripheral blood of 34 RA patients and 15 healthy individuals.Total RNAs were isolated and miRNAs were purified.The levels of miR-155 and miR-146a were determined by quantitative reverse transcription PCR(qRT-PCR).U6 was used as housekeeping control.The amount of target miRNA was normalized relative to the amount of U6(ΔCt=ΔCtmiRNA-ΔCtU6).Relative expression levels were expressed as 2 △-ΔCt.Data were analyzed using SPSS 13.0 software.The test of homogeneity of variance and unpaired t-test was used to compare between groups.P values(2-tailed) less than 0.05 were considered as statistically significant.ResultsThe expressions of PBMC and plasma miR-155 were higher in RA patients than those in the healthy control individuals(0.08±0.08 vs 0.05±0.03,t=-2.225,P＜0.05; 5.9±6.7 vs 1.3±2.0,t=-3.677,P＜0.05).The expression of miR-146a in PBMC and plasma of RA patients and controls were(1.3±1.2 vs 0.8±0.6,t=-2.154,P＜0.05)and(741±1001 vs 300±295,t=-1.669,P＞0.05).According to their DAS28 value,RA patients were divided into high activity group (23 cases,DAS28≥5.0) and low disease activity group( 11cases,DAS28＜5.0).The plasma miR-155 and miR-146a expressions were significantly higher in high activity group than those in low activity group.There were no significant differences in the expression of PBMC miR-155 and miR-146a between the two groups.ConclusionThe expression of PBMC and plasma miR-155 and miR-146a are higher in RA patients.The expression of plasma miR-155 and miR-146a are associated with RA patients' activity.Plasma miR-155 and miR-146a may be potential non-invasive biomarkers for RA diagnosis anddisease activity assessment.

Objective To improve the operation method of rupture of Achilles tendon for decreasing complication. Methods Total 39cases with closed rupture of Achilles tendon were selected in this study. Short incision was made at achilles tendon wall, reveal and anneal the broken ends, using Kirschner wire and steel-wire to make rectangle frame ,intradermic fixation of fracture away from the broken ends, then sutured ends with rarities and smoothing,functional exercise after 6weeks ankle rest position fixation. Results According to the Arner Lindholm evaluation system,the treatment outcome were excellent in 34 cases ,and good in 5cases. No complication including re-rupture skin ,tendon necrosis and infection were found after operation. Conclusion Repaired closed rupture of Achilles tendon with short incision and rectangle frame, assisted with ankle rest position fixation after operation wasa worthy way for treating closed rupture of a chilles tendon.

Objective To analyze and explore the operative effect of coraccid process basilar part fractures combined injury of ligamental structure. Methods Use ilium-fascia lata complex tissue to reconstruct coronoid process of ulna and medial collateral ligament, recoverd anterior and wall horn anatomic structure of elbow joint. Total 9 cases of ulna coracoid process fractures concomitancy with elbow posterior dislocation . Among these one with olec-ranon fracture,five patients with head of radius fracture. Anterior trance joint approach was used,removal bone chips, restore defect with ilium-fascia lata complex tissue after cuting and trimming. Once reduction was achieved,fixed with screw. Repaird the collateral ligament and anterior joint capsule use the fascia lata, If there were combined fracture of the radius head or olecranon fracture,fixed through lateral approach,All injured extremities were treated with a posterior plaster splint with functional position for 3 weeks followed by elbow rehabilitation training. Results According to Moneys evaluation method,2 patients were classified as excellent ,5 as good,l as fair and 1 as poor. The excellent and good rate was 77. 8%. Two patients with gently ossifying myositis but no patients with wound infection,internal fixation loosening or break,elbow joint destabilizing orcorpus libemm. Conclusions Coracoid process basilar part fractures was simultaneous with the instability of osteal frame and soft tissue. To attain the favourable anatomical foundation for elbow joint functional recovery, it should rebuild the height and shape of coronoid process first and think highly of repair or rebuild medial collateral ligament and joint capsule. It reconstructed the coronoid process osteal frame and soft tissue instability at the same time to use ilium-fascia lata complex tissue. The operative procedure is simplify with reliability effect and fine functional rehabilitation.

Objective To investigate the curative effects of the traditional surgical method of posterior pedicle Schanz screw fixa-tion with partially stripping injured paravertebral muscle in treating thoracolumbar fracture .Methods 52 cases with thoracolumbar fracture underwent posterior pedicle Schanz screw fixation to partially strip injured paravertebral muscle from January ,2010 to Jan-uary ,2012 .The patients were divided into partially stripping injured paravertebral muscle group (32 cases) and traditionally strip-ping injured paravertebral muscle group(20 cases) .The blood loss ,postoperative drainage ,kyphosis postoperative 3 d VAS scores , vertebral height correction rate ,Cobb angle correction ,Oswestry dysfunction indexes were copmared .Results Comparing with tra-ditionally stripping injured paravertebral muscle group ,the partially stripping injured paravertebral muscle group has better effect in transperative blood loss ,postoperative drainage and postoperative 3 d VAS scores ,the differences were statistically significant .But there was no statistical significance between the two groups in vertebral height correction rate ,kyphosis Cobb angle correction ,Os-westry dysfunction indexes .Conclusion Partially strip injured paravertebral muscle has less painful than traditional surgery does , being safe and effective with small invasion and easy to recover .
