Objective To study the prevention of gentamicin ototoxicity by resveratrol(Res) in guinea pigs.Methods Auditory brainstem response and cochlear preparation transmission electron microscope were used to evaluate the effects of hair cell on hearing threshold and morphology of hair cell. Serum levels of GM were also tested. It was comprised of five groups,each group had eight animals.GM and Res were tested alone and in combination,besides control group.Results GM group developed a progressive threshold shift. Injury in high frequency was significantly more severe than that in low frequency (P

Objective To study the biomechanics of posterior lumbar interbody fusion with unilateral fixation.Methods 15 bovine lumbers were divided into three groups(intact group,spondylolisthesis group,posterior lumbar interbody fusion with unilateral fixation group as experimental group).Nondestructive tests were performed in pure compression,flexion,extension,and lateral bending on every group.Results Compared with intact group and spondylolisthesis group,after posterior lumbar interbody fusion with unilateral fixation,the mean straining of vertebral body in experimental group increased.The value of experimental group had significant difference from spondylolisthesis group(P ＜ 0.01,P ＜0.05).And the value of experimental group was proximal to intact group (P ＞ 0.05).Conclusion After operation with posterior lumbar interbody fusion with unilateral fixation,the stiffness of vertebral body was approached the intact group during axis compression,flexion,extension and lateral bending.And the initial stability was enough after operation.

ObjectiveTo determine whether the Chinese version of 36-item Short Form Health Survey (SF-36) can be taken as an effective assessment to evaluate the quality of life in patients with knee osteoarthritis. Methods30 patients with knee osteoarthritis were tested twice in 3 d with the Chinese version SF-36 by two standard-trained testers. The Cronbach's α coefficient and intraclass correlation coefficient (ICC) were investigated. ResultsThe ICC of total scores and parts scores in the Chinese version SF-36 were 0.54～0.91, while the Cronbach's α coefficients were 0.70～0.95. ConclusionThe Chinese version SF-36 is reliable in evaluating the quality of life in patients with knee osteoarthritis.

Objective To summarize our experience in treating high risk carotid stenosis. Methods We retrospectively analyzed the clinical characteristics, treatment, and outcomes of 24 patients with high risk carotid stenosis in our department from January 2001 with emphasis on the application of carotid stents and shunting tubes. Results All patients were successfully treated, with 11 patients undergoing carotid angioplasty and stenting (CAS) and 13 patients receiving carotid endarterectomy (CEA) and shunting. No death, stroke, and ischemic neurological deficit occurred in 30 days postoperatively. Conclusion Selective application of CAS and shunting in CEA can effectively reduce complications and improve therapeutic effects in patients with high risk carotid stenosis.

Objective To investigate the effect of costimulatory molecules 4-1BB/4-1BBL on T cell activation with systemic lupus erythematosus(SLE)patients.Methods The expression of NF-kB mRNA and p38 MAPK mRNA of T cells with 20 SLE patients and 20 normal controls before activation,after activation and blocked bv 4-1BB/4-1BBL were detected bv RT-PCR.The protein levels of p-p38 MAPK and NF-kB were detected by Western blot.Results The expression of NF-kB mRNA and p38 MAPK mRNA and the protein expression of NF-kB and p-p38 MAPK of T cell with SLE patients were higher than that of normal controls(P＜0.01).There were more expression of NF-kB mRNA,p38 MAPK mRNA,NF-kB protein and p-p38 MAPK protein of T cell with SLE patients stimulated by anti-CD3 monoantibody(P＜0.01).In anti-4-1BB monoantibody blockage group,there were decreased expression of p38 MAPK mRNA and p-p38 MAPK protein(P＜0.01).but not the decreased NF-kB mRNA and protein expression.Conclusion Costimulatory molecule 4-1BB plays a critical role in T cell activation of SLE by p38 MAPK signal pathway.

Objective To explore the influence of interbody fusion intervertebral fixation on adjacent joint degeneration in patients with lumbar diseases .Methods 56 patients with lumbar diseases who were taken interbody fusion intervertebral fixation were selected as the research subjects ,and the adjacent intervertebral joint degeneration in patients were followed up .Results 56 patients were followed up for 24-72 months,the average time was (41.2 ± 8.3)months.The new clinical symptoms were occurred in 12 cases(21.4%),including 8 cases of low back pain, 3 patients with leg pain,1 case of lumbocrural pain.Radiographic changes occurred in 9 cases(16.1%),9 cases of patients with new clinical symptoms ,including 5 cases of osteophyte formation or exacerbation ,2 cases for adjacent segment instability ( I degree of vertebral spondylolisthesis ) ,1 case of small joint hyperplasia stage spinal stenosis , 1 case of protrusion of intervertebral disc .In 9 patients with imaging performance ,internal fixation of upper adjacent segment degeneration in 7 cases,internal fixation of the adjacent segment degeneration in 2 cases.Conclusion Inter-body fusion intervertebral fixation in the treatment of lumbar diseases ,adjacent joint is prone to degeneration ,so the destruction of adjacent joint operation should be reduced .

Objective To study the expression of polycystin1 and polycystin2 in dissection aorta specimens by Real time PCR and immunohistochemisty. Methods Twelve descending dissection aorta specimens from patients of acute Stanford B dissection were taken during surgery; 12 normal descending aorta specimens were taken from multi-organ donors. The G APDH gene was used as control, gene expression of polycystinl and polycystin2 were compared in these two groups with Real time PCR. The expression of polycystinl and polycystin2 protein were showed with immunohistochemisty in the specimen of these two groups. Three high magnify fields were randomly chosen to count the expression of polycystin1 and polycystin2 protein. The counting of polycystin1 and polycystin2 protein were compared between these two groups. Results The gene expression of polycystinl in AD group is 0. 32 fold as that in the control group (P ＜ 0.01 ) and polyeystin2 in AD group is 0.34 fold as that in the control group (P ＜0.01 ); The protein expression of polyeystinl was 0.47 folds as that in the control group ( P ＜ 0.05 ) and polycystin2 in AD group is 0.35 folds as that in the control group ( P ＜ 0.01 ). Conclusions The expression of polycystin1 and polycystin2 on gene and protein level were down regulated in AD group. The down regulation of polycystinl and polycystin2 may play a pivotal role in the development of AD.

Objective To investigate the diagnosis and the effect of microsurgery in patients with acute spontaneous spinal epidural hematoma (ASSEH). Method Five patients with ASSEH treated with microsurgery and confirmed pathologically were retrospectively analyzed. Results The main clinical presentations were root pain and palsy. The main manifestations of MRI were long-segment epidural lesion of high intensity in T1 and T2-weighted images without enhancement. With the microsurgery system, laminectomy via posterior approach and hematoma removal were successfully undergone with full recovery in all cases. Conclusions MRI assisted with the main clinical symptoms may aid preoperative diagnosis in symptomatic ASSEH. Microsurgery is an effective method for treating ASSEH. Postoperative (rather than preoperative) spinal DSA is advantageous for exclusion of spinal vascular malformation in treating ASSEH.
