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.

BACKGROUND:Previous studies have found that the susceptibility genes of adiponectin gene and calpain 10 gene of type 2 diabetes are closely related with the incidence of diabetes in Chinese renal transplantation patients. So, are other susceptibility genes of type 2 diabetes also associated with posttransplantation diabetes mel itus? OBJECTIVE:To investigate the association between the zinc transporter solute carrier family 30 member 8 (SLC30A8) gene polymorphism and the posttransplantation diabetes mel itus. METHODS:A total of 97 patients with posttransplantation diabetes mel itus and 301 patents without posttransplantation diabetes mel itus (control group) were selected, and then the SLC30A8 gene rs13266634 genotype was detected with real-time PCR method. The association between gene polymorphism and posttransplantation diabetes mel itus was analyzed with Logistic regression test. RESULTS AND CONCLUSION:There were significant differences in al ele frequencies and genotype distributions of rs13266634 between the patients with and without posttransplantation diabetes mel itus (P<0.05). After adjustments of age, sex, body weight and body mass index, the incidence of posttransplantation diabetes mel itus of the CC genotype patients was 2.108 times to that of the TT genotype patients (odds ratio=2.108, 95%confidence interval:1.075-4.131, P=0.044);and the incidence of posttransplantation diabetes mel itus of the CC+CT genotype patients was 1.862 times to that of the TT genotype patients (odds ratio=1.862, 95%confidence interval:1.049-3.306, P=0.034). The results suggest that the C-al ele in rs13266634 of SLC30A8 gene is the independent risk factor of posttransplantation diabetes mel itus.

Objective By using cardiac ischemia reperfusion model, the muscarinic receptor path way of cardiac signal conduction in both young and aged myocardium was studied. The aim was to study the pathogenesis of ischemia reperfusion injury in aged myocardium. Methods 20 dogs (15～20 kg) were randomly divided into two groups: group A (young, 3～4 years old, n=10), group B (old, 7～8 years old, n=10). All dogs underwent 60 minutes of global ischemia and 30 minutes of reperfusion under cardiopulmonary bypass (CPB). A tunnel was inserted through the left ventricular apex, to measure the LVEDP、+dp/dt、-dp/dt and ECG. . Myocardial specimens were collected at the beginning of reperfusion, 30 min after reperfusion and 60 min after reperfusion. Myocardium was prepared or studied of density of muscarinic receptor, G protein level, cGMP, guanylate cyclase activity, value of NO, protein level of eNOS, mRNA level of iNOS and eNOS. Results (1) Group B had higher LVEDP but lower +dp/dt max and -dp/dt max than group A in each stage. After CPB, the LVEDP showed no difference between pre and post surgery in two groups, while +dp/dt max and -dp/dt max were decreased in both groups, more significantly in group B. (2) At 30 min and 60 min after reperfusion, the density of M receptor was significantly increased in group B than that in group A. (3) There was no significant difference in Gs pre and post surgery in group A. Compared with group B, the level of Gi decreased significantly after the reperfusion in group A. There were decreasing in Gs and Gi after reperfusion in group B, more greater in the former. The ratio of Gi/Gs in group B was much higher than that in group A. (4) Compared with group A, the mRNA level of eNOS and protein level of eNOS decreased more significantly in group B during each stage of reperfusion. After ischemia reperfusion, the mRNA level of iNOS, NO, cGMP and guanylate cyclase activity were obviously increased in group B than that in group A.Conclusion (1) After the cardiac surgery in elder model, the M receptor path way increased significantly, which is negatively correlated with cardiac function, hence promote the ischemia reperfusion injury in elder myocardium. (2) In the ischemia reperfusion injury in elder myocardium, higher vagotonic does more harm to the old myocardium through NO and NO cGMP pathway.

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.

Objective To discuss the implications of orbital septum repairing and crimpling in the plastic surgery of lower eyelid bags. Methods The ultimate results were analyzed in the patients (aged less than 40) who received three different operations from six months to five years and the effect of operation and recrudescence of lower eyelid sag were observed. The procedures included simple fat removal, fat removal plus orbicularis oculi hanging, and orbicularis oculi hanging plus orbital septum repairing and crimplling. Results Since 2002, 157 cases were treated, and the ultimate effects of patients were analyzed. 86 cases treated with orbicularis oculi hanging plus orbital septum repairing and crimplling reached the best results without recurrence. 71 cases treated with simple fat removal or fat removal plus orbicularis oculi hanging experienced recurrence in different degree within a short period. Conclusion The weakness and laxation of the former wall causes the formation of lower eyelid bag, the appearance and recrudescence mainly locate below the former wall. Orbital septum repairing and crimpling most effectively strengthen the underside of the former wall. Orbicularis oculi hanging strengthens the top of the former wall and prevents any complications. The effects of the last procedure are better than that of the other two in the near future or in the long term.
