Objective To provide anatomical evidence for a safe osteotomy line and direction in periacetabular osteotomy.Methods The pelvic CT images of 18 adults were obtained.With the help of Mimics software,three-dimensional CT reconstruction was performed,and periacetabular osteotomy was simulated.The length of osteotomy lines on the ilium,ischium and iliac columna posterior was measured,and the relationship between osteotomy lines and anatomic landmarks was explored. Results The length of osteotomy lines on the ilium,ischium and iliac columna posterior was(50.96?7.09) mm,(36.46?5.92)mm and(55.28?6.42) mm,respectively.The angles between the osteotomy line on the ilium and that on the iliac columna posterior,between the osteotomy line on the ischium and that on the iliac columna posterior,and between the osteotomy line on the iliac columna posterior and quadrilateral surface were 120.21??5.96?,115.49??6.46? and 60.31??4.96?,respectively.And the real periacetabular osteotomy has been performed on the pelvic specimens for verification.The vertical distances between the ending point of osteotomy line on the ilium and iliopectineal line,between osteotomy line on the ischium and iliopectineal line,and between the osteotomy line on the iliac columna posterior and greater sciatic notch were(11.98?5.26) mm,(45.08?8.59) mm and(18.52?6.49) mm,respectively. Conclusion The length and angles of osteotomy lines in periacetabular osteotomy can be well measured by three-dimensional reconstruction,and the relationship between the osteotomy lines and anatomic landmarks can also be well displayed,which provides anatomical data for the clinical application of periacetabular osteotomy.

Background The ubiquitin-proteasome pathway(UPP)involves 80%-90% degradation of all in- tracellular proteins.Both ubiquitin and rat component 3 of proteasome(RC3)are hence considered to be central me- diators for cell biology.Objective To evaluate the effect of simvastatin on neointimal hyperplasia and the expres- sion of ubiquitin and rat component 3 of proteasome(RC3)after balloon injury in carotid artery.Methods Thirty- two male SD rats were randomly to receive,low dose(0.4 mg/ng,n=8),or moderate(4 mg/ng,n=8),or high- dose(40 mg/ng,n=8)of simvastatin treatment for 28 days.Common carotid aortic artery was injuried rat ballon. The ratio of intima-media(I/M)thickness was determined.The expression level of ubiquitin and RC3 mRNA were assessed by RT-PCR.The expression level of ubiquitin protein was examined with immunohistochemistry. Results Simvastatin inhibited the expression of ubiquitin and RC3 mRNA and ubiquitin protein in dose dependent manner.The intima-media ratio(-50.2 %)and the expression of ubiquitin(-60.3 %)and RC3 mRNA and ubiq- uitin protein(-60.5 %)was reduced by the high dose simvastatin [40 mg/(kg?d)](P

Objective To explore the relationship between cough variant asthma (CVA) and mycoplasma pneumoniae (MP) infection.Methods Fifty children with CVA were chosen as the experimental group at random,and 50 children with acute upper respiratory infection,who went to the hospital in the same time and with similar age,were chosen as control group.The MP-IgM of children in both groups were tested by the granule agglutinating method.Results Significant difference (? 2=9.013 P

0.05).Setting the threshold of MOV at 6.4 cm~3 offered the best compromise between sensitivity (84.8%)and specificity(87.5%),and setting the threshold of MaxOV at 8.6 cm~3 offered the best compromise between sensitivity(75.8%)and specificity(95.2%)and setting the threshold of MFN at 8 offered the best compromise between sensitivity(86.7%)and specificity(78.3%).Conclusions Ovarian morphology by ultrasonography yields satisfactory diagnostic accuracy for adolescent PCOS.Taking MOV≥ 6.4 cm~3 or MaxOV≥8.6 cm~3 or MFN≥8 as an ultraphonic criterion for pubertal PCOS offer the best compromise between sensitivity and specificity.

Dystonia is a common movement disorder characterized by abnormal gestures and involuntary movement as a result of incoordinate contraction of agonistic and antagonistic muscles.The underlying pathogenesis is very complicated and there are various clinical manifestations.The recent findings in genetics and clinical features of primary dystonia,dystonia-plus syndrome and heredodegenerative dystonia are introduced in this paper.
