AIM: To observe the improvement effects of berberine on glycated brain damages in model rats induced by D-galactose. METHODS: The model rats of protein glycation were induced by intraperitoneal administration of D-galactose(150 mg/kg?d) for 8 weeks,and all rats were treated with berberine(high dose 300 mg/kg,middle dose 150 mg/kg,low dose 75 mg/kg) for 6 weeks.The activity of aldose reductase in red blood cells,the amount of glycated products(fructosamine in serum,glycohaemoglobin,advanced gtycation end-products),and the content of AGEs in brain tissue,calcium ion in brain cells were measured.Moreover,mitochondria in brain hippocampus cells were observed under electronic microscope. RESULTS: High dose and middle dose of berberine could decrease the activity of aldose reductase in red blood cells(P

Objective To study the effect of dialysis adcquacy,microinflammation and residual renal function on nutritional status of hemodialysis patients.Methods One hundred and fourteen patients were enrolled in this study.Kt/V,?_2-MG and serum iPTH were measured as markers of hemodialysis adequacy.Nutritional evaluation included MQSGA,Alb,Hb,TF,IGF-1,IGFBP-3 and anthropometrics such as HGS,BSF,TSF,MAC,MAMC and AMA.Serum IL-6,TNF-?and CRP were detected to assess microinflammation.Urinary volume of 24 hours was measured to investigate the residual renal function (RRF).Results (1)There were different correlations and regressive associations of Kt/V,iPTH and?_2-MG with HGS,MAMC,AMA,Alb,Hb,nPCR,IGF-1 and MQSGA respectively.(2) There were significant correlations and regressive associations of RRF to HGS,TSF,MAMC,Alb,nPCR and IGF-1 within the first year of hemodialysis.(3) There were different correlations and regression relationships of IL-6,TNF-?and CRP with HGS、MAMC、AMA、Alb、TSF、Hb、nPCR、IGF-1 respectively.(4) Multivariate analysis showed that Kt/V,iPTH,IL-6, TNF-?,?_2-MG and RRF were influencing factors,among them,Kt/V,iPTH,IL-6 and TNF-?were independent predictors of nutritional status.Conclusions Hemodialysis adequacy and micruinflammation may impact on nutritional status.Residual renal function may be involved in nutritional status in the first year of hemodialysis.Kt/V,iPTH,IL-6 and TNF-?are independent factors affecting nutritional status.

Objective To study the imaging of inner ear malformations in children with congenital sensorineural hearing loss(SNHL).Methods CT and MRI examinations were performed on children with SNHL diagnosed by audiological test.One hundred and eighty-eight patients with complete imaging information were obtained.The imaging of inner ear malformations was analyzed according to Sennaroglu's classification. Results Thirty-five patients(54 ears) were found with inner ear malformations by CT and MRI,3 of whom(5 ears) were accompanied by outer and middle ear malformations.Among the 35 patients,2(4 ears) were found to be common cavity deformity,1(1 ear) cochlear hypoplasia,13(26 ears) incomplete partition II(Mondini deformity),4(7 ears) vestibule dilation,13(19 ears) semicircular canal deformity and 19(34 ears) large vestibular aqueduct.Internal auditory canal was found narrow in 7 patients(10 ears) and wide in 1(2 ears) with classic Mondini deformity. Conclusion CT and MRI examinations are of great importance to the diagnosis and treatment of inner ear malformations in children with congenital SNHL,especially for the candidates of cochlear implantation.

OBJECTIVETo evaluate the curative effect and surigical skills of reconstruction intramedullary nailing in the treatment of ipsilateral femoral neck and shaft fractures.

METHODSFrom January 2007 to January 2013, 13 patients with ipsilateral femoral neck and shaft fractures were treated by reconstruction intramedullary nailing including 11 males and 2 females with an average age of 38.9 yeas old ranging from 25 to 53 years old. For femoral neck fractures,10 cases were basilar neck fracture, 3 were transcervical fractures and according to Garden classification,10 were type II, 2 were type III and 1 was type IV. For feormal shaft fracture, 5 were type I, 4 were type II, 3 were type III and 1 was type IV according to Winquist classification. The location of all 13 feormal shaft fractures were all in the uper 3/4 of the feormal shaft. Complications and postoperative function were recorded and evaluated.

RESULTSEleven patients were followed up for 23.45 months (12 to 36 months). Time from injury to operation was 5.9 days in average. Malunion of femoral neck fracture happened in 1 patient, nonunion of femoral shaft fracture happened in 2 patients. NO femoral head osteonecrosis, infection and malunion of femoral shaft fracture happened. According to Friedman-Wyman classification, 8 cases get good result, 2 get faii and 1 get poor.

CONCLUSIONReconstruction intramedullary nailing is a good choice for the ipsilateral femoral neck and shaft fractures with the advantages of less soft-tissue trauma and complications.

Objective To evaluate biomechanical effect of bone cement distribution on lumbar vertebral body with osteoporotic fracture.Methods Forty nine lumbar vertebrae (L1-L5) specimens were collected from 12 old cadavers.After exerting axial pressure load on every specimen,the initial intensity and stiffness were measured,and then vertebral body crush fracture models were established.According to zones where bone cement was injected in vertebrae,the specimens were divided into one control group and six experimental groups:A,B,C,D,E,F groups,i.e.unilateral anterior 2/3 group,unilateral posterior 2/3 group,unilateral whole group,bilateral anterior 2/3 group,bilateral posterior 2/3 group,and bilateral whole group,respectively,including 7 specimens in each group.In A,B,C groups,unipedicular balloon kyphoplasty was done,while in D,E,F groups,bipedicular balloon kyphoplasty was done.Then the maximum compressive strength and stiffness were measured.Results After percutaneous kyphoplasty,the maximum strength in all experimental groups was significantly greater than that in the control group.There were no significant differences in strength between A and B groups,between C,D and E groups.For the maximum strength,the results of comparison were:F group ＞ C group,D and C groups ＞ A and B groups.Except for F group,the stiffness in other 5 experimental groups was significantly lower than its initial value.There were no significant differences in stiffness between A,B,and C groups,between D and E groups.However,the stiffness in F group was greater than those in D and E groups,and it was greater in bilateral groups than those in unilateral groups.Conclusion Bone cement distribution in lumbar vertebral body can affect biomechanical property of vertebral body,and the bilateral distribution can cause better biomechanical effect than unilateral distribution.The ideal distribution zone of bone cement is in the anterior 2/3 of the vertebral body.

Objective To summarize the clinical characteristics,diagnosis and treatment of malignant tumor after renal transplantation.Methods The clinical data of 2106 renal transplants in 1945 patients undertaken in our hospital from September 1978 to December 2009 was retrospectively studied.Results Of these 1945 patients, 39 cases were diagnosed as having malignant tumor (incidence: 2.0 ％).The interval between transplantation and clinical diagnosis ranged from 8 to 124 months with a median of 57.0 months.Among the 39 cases of malignancy, there were 22 urinary system carcinomas, 8 digestive system carcinomas,2 lung cancers,2 breast cancers,2 lymphomas,1 dura small cell carcinoma,1 pleura poorly differentiated carcinoma and 1 metastatic carcinoma of liver with unknown primary tumor. Surgery was conducted in 28 patients,of which 16 were survived but the other 12 patients died of metastasis ranged from 3 months to 96 months (median,33 months) after operation.11 cases without operation died within from 3 d to 36 months (median,5 months) after diagnosis.Conclusions The incidence of malignant tumors in renal transplant recipients increased markedly.The most common type of the malignant tumors is urinary system carcinoma.The key measure of success in treating malignancy after renal transplantation is early diagnosis and surgical resection.

Objective To analyze reasons of open operation after percutaneous vertebroplasty.Methods From January 2008 to January 2012,516 patients (587 vertebrae) underwent percutaneous vertebroplasty in our hospital.Among them,13 patients occurred serious complications after operation:9 cases of spinal cord injury and 4 cases of nerve root injury.There were 5 males and 9 females,aged from 53 to 72 years (average,64.5 years).There were 10 cases of osteoporotic fracture,2 cases of vertebral metastases and 1 case of vertebral hemangioma.The lesion segments were as follows:T7 in 1 case,T8 in 1 case,T9 in 2 cases,T10 in 1 case,T11 in 1 case,T12 in 2 cases,L1 in 3 cases,L3 in 1 case and L4 in 1 case.According to the American Spinal Injury Association (ASIA) classification,9 patients with spinal cord injury were rated as follows:grade A in 2 cases,grade B in 1 case and grade C in 6 cases.Four patients with nerve root injury had skin hypesthesia,and the muscle strengths of them were grade Ⅱ.All patients underwent posterior open operation 4-12 h after definite diagnosis.Results Thirteen patients were followed up for 3 to 47 months (average,14.1 months).The reasons of open operation were as follows:bone cement leakage in 6 cases (46.2％,6/13),puncture failure in 3 cases (23.1％,3/13) and indication select error in 4 cases (30.8％,4/13).All 6 cases of bone cement leakage were non vascular leakage,including 2 cases of leakage into the spinal canal and 4 cases of leakage into the nerve root canal.At final follow up,the muscle strength was improved to grade V in 3 patients with nerve root injury and grade Ⅳ in remaining 1 patient.And skin sensation was also improved.The ASIA grade of 7 patients with spinal cord injury was improved:grade D in 4 cases and grade E in 3 cases.For remaining 2 patients,there was no change in ASIA grade.Conclusion The reasons of open operation after percutaneous vertebroplasty include bone cement leakage,puncture failure,and indication select error.And bone cement leakage is the most common.
