BACKGROUND: During the hip replacement, selection of prosthesis often depends on patients' bone condition. There has been no gold standard for selection of prosthesis. It will be of scientific significance to select femoral prostheses implanted under different bone densities through three-dimensional finite element analysis and simulated contrast mechanical tests.OBJECTIVE: Three-dimensional finite element analysis was employed to select femoral prostheses according to different bone densities, and simultaneously simulated contrast mechanical tests were performed to determine the age criteria regarding the selection of femoral prosthesis during the hip replacement.DESIGN, TIME AND SETTING: An open experiment was performed at the Second Department of Orthopedics, First Clinical Hospital of Jilin University and Institute of Biomechanics, Jilin University between September 2006 and May 2007.MATERIALS: Freshly adult femoral specimens were harvested from cadavers.METHODS: Three-dimensional finite element models of femur were established using Solidworks software. Following the known formula, the bone density and elastic modulus at different age brackets were calculated and input into the computer. The human one-foot standing condition was simulated and pressure was loaded on the reconstructed femoral models.MAIN OUTCOME MEASURES: Some biomechanical characteristics of uncemented and cemented femoral prostheses, such as the distress distribution and initial micromovement at different bone densities, were measured.RESULTS: Relatively well-distributed whole distress and slight initial micromovement of uncemented femoral prostheses were found in male patients at 30-60 years old and in female patients at 40-55 years old. Symptoms of cemented femoral prostheses the same as the uncemented femoral prostheses were present in male patients at 60-70 years and in female patients older than 55 years old.CONCLUSION: Results of three-dimensional finite element analysis and simulated contrast mechanical tests suggest that uncemented femoral prostheses provide better therapeutic effects in male patients younger than 60 years and in female patients younger than 55 years than cemented femoral prosthesis.

BackgroundCycloplegia is well accepted for the first refraction estimate in childhood.Yet no good evidence is offered in terms of which cyclopegia is preferable for the different ages and refractive status in children. ObjectiveThis study aimed to compare the effectiveness of cycloplegia between 1% cyclopentolate and 1% atropine sulphate before optometry in ametropia children. Methods This was a prospective clinical trail.The self matched-pairs control randomly observation was designed.One hundred and sixty eyes of 80 children of 4-9 years old with refractive error were recruited in this study.1% cyclopentolate eye drops were topically administered once per 5 minutes for 3 times and 1%optometry was performed 45 minutes after eye dropping.Three days after that,1% atropine then was used 3 times per day for consecutive 3 days and again the refractive diopter was obtained.The differences of the results in autorefraction,retinoscope and residual accommodation were compared between 1% cyclopentolate and 1%atropine eye drops.This trail was approved by the Ethic Committee and written informed consent was obtained from each custodian. Results The autorefraction values were ( 0.55 ±3.52 ) D and ( 2.22 ±3.52) D before and after the administration of 1% atropine with the difference value( 1.66± 1.62) D (t =13.02,P =0.00 ).The autorefraction value was( 1.74±3.46 ) D after dropping of 1% cyclopentolate and the difference value from that of 1% atropine was (0.48 ± 0.46) D ( t =13.08,P =0.00 ).The cy(e)lplegic autorefractions of atropine and cyclopentolate have strong correlation ( R2 =0.98,P =0.000 ).The residual accommodation values were ( 0.32± 0.44 )D and(0.05±0.41 ) D after dropping of 1% cyclopentolate and 1% atropine with the difference( 0.27±0.55 ) D ( t =4.56,P =0.00 ).The difference value of refractive diopter was (0.31 ± 0.37 )D in myopic group,(0.56±0.48 )D in moderate hypermetropic group and(0.59±0.50)D in high myopic group,and that of myopic group was significantly lower than the moderate hypermetropic group ( t =- 3.14,P =0.00 ).No significant difference was found in the autorefraction difference between 4-6 years group and 7 -9 years group [ ( 0.61 ±0.53 ) D vs ( 0.49 ±0.39 ) D ] ( t =1.21,P=0.23 ).The hidden value because of accommodation had weak correlation with the difference value between atopine and cyclopentolate(r=0.43,P=0.00). ConclusionsBoth 1% atropine and 1% cyclopentolate have the cycloplegic effects.This study suggestes that 1% atropine should be used for the optometry of hypermetropia children.

BACKGROUND: Anemia after kidney transplantation has a clinical incidence rate of 30%-40%, is the important risk factor for cardiovascular diseases and kidney failure after kidney transplantation and is also the independent prediction index of patient's death. OBJECTIVE: To analyze the factors related to anemia after kidney transplantation. RESULTS AND CONCLUSION: In the anemia group (n = 225, 27.2%, aged 26-65 years), the incidence rate of anemia in female and male patients was 23% and 37%, respectively (P < 0.05), 46 patients had hypertension and used angiotensin-converting enzyme inhibitor or angiotensin Ⅱ receptor antagonist and 16 patients had chronic erosive gastritis or upper gastrointestinal tract ulcer, with the human survival rate of 85.3% and kidney failure rate of 25.3%. In the non-anemia group (n = 601, 72.8%, 405 males, 196 females, aged 18-71 years), 35 patients had hypertension and used angiotensin-converting enzyme inhibitor or angiotensin Ⅱ receptor antagonist and 14 patients had chronic erosive gastritis or upper gastrointestinal tract ulcer, with the human survival rate of 92.1% and kidney failure rate of 12.6%. There was significant difference in above-mentioned indices between anemia and non-anemia groups (P < 0.05). These results suggest that gender, age, kidney function, digestive tract disease history, and drug application are closely related to anemia after kidney transplantation.
