ObjectiveTo investigate the effort of MHA-bBMP implantation combined with limited contacted titanium net duct fixation on femoral shaft bone defect of rabbit.Methods48 rabbits were divided into the experimental group (treated with bionic bone MHA-bBMP plus titanium net duck) and control group (treated with iliac autograft plus titanium net duct) with 24 animals in each group. The rabbit femoral shaft bone defect model was established by cutting 10 mm bone fragment off. After operation, bionic bone MHA-bBMP/iliac autograft was implanted into bone defect area and fixed with limited contacted titanium net duck. The general condition, serum alkaline phosphatase, X-ray, histopathologic examination and electron microscope were performed.ResultsThe fixation stability of titanium net duck in two groups was good. The bone defect of two groups was repaired. The results of phosphatase, X-ray, histopathologic examination and electron microscope of two groups were not significantly different.ConclusionBionic bone MHA-bBMP is a high bioactivity substitute, and can obtain therapeutic effect equal to iliac autograft when repairing rabbit's femoral shaft defect.

Objective To determine relative risk factors for positive surgical margins in extraperitoneal laparoscopic radical prostatectomy(LRP). Methods From February 2004 to September 2007,33 patients(mean age 70 years old)with prostate cancers underwent extraperitoneal LRP.All patients were diagnosed by pathology preoperatively.Gleason score:3+3 14 cases(43%),3+4 11 cases(33%),4+3 6 cases(18%),4+4 2 cases(6%).Clinical stage:T1a-T1b 4 cases(12%),T1c 14 cases(43%),T2a-T2b 5 cases(15%),T2c10 cases(30%).Logistic regression analyses were performed. Results LRP was successfully performed on 31 cases.There were 2 cases converted to open surgery.Nine cases(27%)had PSMs.There were 6 cases(67%)and 4 cases(17%)of clinical stage T2c in PSM and negative surgical margin(NSM)groups respectively(P=0.010).There were 3 cases(33%)and 0(0)with high Gleason score(higher than 7)in PSM and NSM cases(P=0.015).There were 4 cases(44%)and 5 cases(21%)with t-PSA higher than 20dg/ml in PSM and NSM cases respectively(P=0.178).In these 9 cases,there were 4 cases(44%)positive with DRE.However there were 9 in the 24 NSM cases(38%)(P=0.509).Clinical stage T2c was independently positively correlated with PSM(OR=24.69).High Gleason score(higher than 7)and t-PSA higher than 20 ng/ml were positively correlated with PSM. Conclusions Clinical stage is positively correlated with PSM.It is an independent factor.High Gleason score(higher than 7)and t-PSA higher than 20 ng/ml mignt be the risk factors in predicting PSM and should be used together with clinical stage.Positive DRE findings may be also useful to predict PSM.

AIM: To investigate the effect of glomerular intercellular interaction under high glucose concentration on the production of reactive oxygen species (ROS) and transforming growth factor ?_1 (TGF-?_1) in co-cultured human ECV304 cells, and to study the intervention with tea polyphenols (TPs). METHODS: The endothelial cells were cultured alone or co-cultured with mesangial cells in high glucose media with or without TPs for 0 h, 12 h and 36 h, respectively. The activity of SOD and the content of MDA in the media of the system were detected by spectrophotometry. The expression of TGF-?_1 mRNA in the endothelial cells was measured by using semi-quantitative reverse transcription PCR (RT-PCR). RESULTS: High glucose decreased the activity of SOD, increased the content of MDA and up-regulated the expression of TGF-?_1 mRNA in co-cultured ECV304 cells and the effect became more prominent than the single-cultured cells. TPs interrupted it more effectively. CONCLUSION: These data suggest that there is interaction between mesangial cells and ECV304 cells under high glucose concentration. The interaction may markedly up-regulate the production of ROS and the expression of TGF-?_1 in co-cultured ECV304 cells. TPs may protect ECV304 cells by intervening intercellular interaction.

Objective To investigate the chnical effect of modified transforaminal lumbar interbody fusion (TLIF) on the treatment of lumbar degenerative disease. Methods Sixty-two patients with lumbar degenerative disease were treated by the modified TLIF from June 2007 to May 2009. The preoperative diagnosis was lumbar intervertebral disc herniation with spinal instability (28 cases), lumbar intervertebral disc herniation with lumbar stenosis (27 cases ), degenerative spondylohsthesis (7 cases ). Forty-eight cases were single-level and 14 cases were two-level. The patients were evaluated by observing the fusion rate and comparing the visual analog score( VAS ) and Japanese orthopaedics association (JOA) score of preoperation with those of postoperation. Results All the patients were followed up from 15 to 30 (22.77 ± 3.82)months,no nerve injury,leakage of cerebralspinal,infection,the broken of pedical screws and other complications. The fusion rate of segment was 96.8% at the follow-up after 1 year postoperatively. Judgement by JOA score,the rate of improvement was 93.5%(58/62),excellent in 34 cases,good in 24 cases,fair in 4 cases. The postoperative value of V AS and JOA score were higher than those of preoperation (P ＜ 0.05 ), the values when follow-up of 3 months was performed had no statistic al difference with those of final follow-up (P＞0.05). Conclusion The modified TLIF with fully decompression while reducing the accessing spinal canal complications have good clinical efficacy in treating lumbar degenerative disease.

ObjectiveTo explore the clinical outcomes of posterior lumbar interbody fusion using BTwin expandable spinal spacer with microendoscopic discectomy (MED) for lumbar disc herniation accompanying degenerative instability.MethodsFrom March 2006 to May 2010,87 patients with lumbar disc heniation (only one level) accompanying degenerative instability were managed with posterior lumbar interbody fusion using B-Twin with MED,includeing 49 males and 38 females with an average of 47.6 years(range,37-65).Objective level located in L3,4 in 2 cases,L4,5 in 43,and L5S1 in 41.The patients were treated with single BTwin(Single group,n=51) and double B-Twin(Double group,n=36).Clinical outcomes were evaluated with surgical time,blood loss,visual analogue scale (VAS) scores,Oswestry disability questionnaire (ODI),and the pre- and post-operative disk space heights.ResultsThe patients were followed up for an average of 35.8months (range,12-46).All the patients felt the low back pain and radiation pain disappeared or relieved apparently.The mean preoperative ODI and VAS scores decreased from 78％±3％ to 18％±3％,and (8.70±11.3)to (0.65±10.48) at the final follow-up respectively.Disc space increased from a pre-operative height of (8.76±1.3) mm to a post-operative of (11.8±0.6) mm.ODI,VAS and the disk space heights in all patient showed statistical significance,which revealed no statistical significance between the two groups.However,the operation time,blood loss were statistical difference between the two groups.All the patients achieved solid union or probable union at a mean time of 5.6 months (range,3.9-8.6).ConclusionPosterior lumbar interbody fusion using B-Twin with MED can obtain satisfactory outcomes in the treatment of lumbar disc herniation accompanying degenerative instability.Single B-Twin can get similar clinical outcomes,but shorter surgical time,less blood loss,and less medical costs.

Objective To investigate the clinical significance of retinal binding protein (RBP) and Cystatin C in blood and urine in patients with chronic kidney disease (CKD).Methods One hundred and twenty-one patients with CKD in Nephrology Laboratory of The People's Hospital of Xinjiang Uygur Autonomous Region from Aug.2012 to Jan.2013 were served as the case group.Sixty healthy check-up people were considered as control group.Enzyme linked immunosorbent assay was used to detect RBP and Cystatin C in urine,and the immune turbidimetry testing was applied to detect RBP and Cystatin C in blood.The receiveroperating characteristic (ROC) curve and area under curve (AUC) were applied to evaluate the sensibility and diagnostic value of indexes in CKD.Results The positive rate of RBP,Cystatin C in urine and blood were 89.6％,92.6％,52.5％,59.5％ respectively of 12 patients in case group,higher than those in control group (all value were 0,P ＜0.001).ROC curve showed that the sensitivity of urine RBP and Cystatin C were higher than that in blood of case group.AUC of RBP,Cystatin C level in urine and blood were 0.915,0.974,.655,and 0.623 respectively.And 95％ confidence interval were 0.877-0.954,0.956-0.992,0.575-0.736,0.543-0.702 respectively,and the differences are statistically significant (P ＜ 0.001).Conclusion The sensitivity of urine cystatin C and RBP are significantly higher than that in blood,which might be served as a diagnostic marker of CKD and can provide important basis for clinical diagnosis.
