[Objective]To determine a surgical plan for the treatment of scoliosis. [Methods]A consecutive series of scoliosis patients were admitted from Oct. 1,2007 to Feb. 29,2008. The preliminary operation programs (including diagnosis,operative approach,upper instrumented vertebra,lowest instrumented vertebra,whether to need selective fusion of main thoracic curve and multiple operations) were formulated by the attending physicians.Preliminary operation programs were decided on by a symposium. A comparison was made between the two kinds of programs.[Results]Data from 143 consecutive scoliosis patients were reviewed. The average age at the time of operation was 16.1 years (2-49 years) and the average curve was 56.9? (range,15?~115? ). There were 6 spine surgeons involved in the study. The accepted programs formulated by the symposium occurred in 46 (32.2%) cases. One of these cases was changed in surgical approach and need selective fusion of main thoracic curve,19 in upper instrumented vertebra and 29 in lower instrumented vertebra. There were no changes in diagnosis and need multistage operations. Operation programs were difficult to formulated in patients aged less than 20,with Cobb's angle≤70?and thoracic curve patterns. [Conclusion]Preoperative symposium for treatment of idiopathic scoliosis influenced the preliminary operation programs in 32.2%. Sympoium appears to have a significant role in drawing up a more perfect operation program.

Bone morphogenetic protein-1(BMP-1) and its related molecules are members of metalloendoproteinase astacin family, including BMP-1, mTLD, mTLL-1 and mTLL-2. Even though all of them lack of the ability to induce bone or cartilage formation directly, they play key roles in numerable activities in ECM from embryo to adult, then affect the procedure and the result of osteogenesis and bone remodeling directly or indirectly. They are critical in maturation and deposition of some major collagen types, and in regulating the signaling of some growth factors in TGF-? superfamily by degradation of TGF-? inhibitor such as Chordin. The investigations about tissue distribution of BMP-1 and its related proteinases and also gene knock-out studies strongly indicate that they play key roles in osteogenesis and bone development.

18 years(n=160) were included. CMH method and FPH model were applied to analyse statistically final height of Shanghai children and their midparental height. Results There was a considerable disparity in stature between the Chinese and the Swedish study populations(P

International Classification of Functioning, Disability and Health (ICF) is one of core classifications launched by WHO. This paper discussed interactive model of functioning and disability and terminological system based on ICF and approaches of the developments of standardized measurement instruments.

Objective To probe the new mechanism of simvastatin on high-fat diet-induced kidney dam-age. Methods Female SD rats were subjected to a standard control diet(SCD)or high-fat diet(HFD)for 20 weeks,then the HFD group was randomly divided into HFD group and HFD group with simvastatin treatment (HFD+ST,10mg·kg-1·d-1 )for another 8 weeks. The expression of adiponectin,adiponectin receptors R1 and R2, Adenosine 5′-monophosphate(AMP)-activated protein kinase(AMPK),peroxisome proliferator-activated receptorα(PPARα),glucose regulated protein 78(GRP78)and GADD153(CHOP)in kidney were assessed respective-ly. Results Body weight and serum lipid levels in HFD group significantly increased ,expression of adiponectin and its receptors significantly down-regulated. Phosphorylation of AMPKα and PPARα expression decreased,and expression of GRP78 and CHOP up-regulated significantly. Above indexes in simvastatin treatment groups improved significantly. Conclusion Simvastatin can improve high-fat induced kidney damages ,probably by increasing expression of adiponectin and its receptors ,decreasing endoplasmic reticulum stress.

Analgesics are widely used in fracture patients before and after operation.The analgesics frequently used include non-steroidal anti-inflammatory drugs,as well as central nerve and local medications.Recently,researches report that some analgesics may inhibit fracture healing,which has attracted much attention from orthopedic surgeons.However,there are researchers who hold opposite opinions.Accordingly,this paper reviews the progress in research concerning the effect of analgesics on fracture healing.

The imaging techniques have been widely used in the diagnosis of chronic osteomyelitis,including plain radiography,magnetic resonance imaging,computed tomography and radionuclide imaging.Plain radiography is useful in the early detection of suspected osteomyelitis,but its sensitivity is low.Due to its high resolution and sensitivity,MRI has been the most widely used but its specificity is relatively poor.CT is mainly recommended for diagnosis of chronic osteomyelitis in complicated anatomic regions.Radionuclide imaging will have prospects of broad application due to its diverse radiotracers and high sensitivity.This paper reviewed the research of imaging modalities in diagnosis of chronic osteomyelitis.

Objective To investigate the adrenal histopathology damage in critically ill non-survival children,and the incidence of adrenal damage,and to explore the risk factors for the adrenal hemorrhage and necrosis in critically ill children.Methods A total of 141 critically ill non-survival children was admitted in this study in Hunan Children's Hospital from January 1,2005 to December 30,2012.Clinical data in children were systematically collected,including age,sex,sodium,potassium,blood gas analysis,liver and kidney function,blood clotting function,etiology,treatment and pediatric clinical illness score (PCIS) or neonatal critical illness score (NCIS),and pathological data.All data were analyzed by SPSS 18.0.Results Logistic regression analysis showed the factors of adrenal hemorrhage and necrosis of critically ill non-survival children were sepsis,PCIS score ＜ 80 critically ill children are risk factors for adrenal hemorrhage necrosis (P ＜ 0.05),ORwas 3.659 (95％ CI:1.344-9.965),and 2.325 (95％ CI:1.028 -5.258).Intravenous corticosteroids were protective factors for critically ill non-survival children with adrenal hemorrhage necrosis (P ＜ 0.05),and ORwas 0.377 (95％ CI:0.163-0.875).Conclusions There were two significant risk factors of adrenal hemorrhage and necrosis:sepsis and critical illness score less than 80 points.Intravenous corticosteroid is a protective factor in critically ill children.

Objective To understand the result coincidence of 4 hematology analyzers (LH780 ,LH750 ,XN-1000 ,and XS-1000i) .Methods 20 samples of routine blood test were selected and detected by different hematology analyzers whose within-run precision and between-run precision all met the requirements of WS/T 406 standard .LH750 was chose to be the reference instru-ment ,and its detection results were standard values .The relative deviations and coincidence rates of WBC ,RBC ,Hb ,HCT , PLT ,MCV ,MCH and MCHC of the other 3 hematology analyzers were calculated .The WBC and PLT coincidence results of 82 cases of low-WBC samples ,86 cases of low-PLT samples ,and 35 cases of platelet aggregation samples were investigated .Results The coincidence rates of all items were more than 90% between LH780 and LH750 .For XN-1000/XS-1000i ,the coincidence rate was 80% in HCT ,and which were less than 80% in MCV and MCHC ,and more than 85% in other items .After readjusting the calibration factors of HCT of XN-1000 and XS-1000i ,the coincidence rates of HCT ,MCV and MCHC were all increased to more than 85% .The coincidence rates of WBC and PLT were less than 70% in low-WBC samples (WBC<1 .0 × 109/L) and low-PLT samples (PLT<30 × 109/L) .The results of WBC and PLT could not reach the relative deviation standards in 35 platelet aggrega-tion samples .Conclusion The comparative tests should be carried out among different hematology analyzers in one laboratory .

Osteomyelitis,particularly chronic one,is still a huge challenge to orthopedic surgeons.The current treatment for osteomyelitis centers on sensitive antibiotic coverage and surgical debridement of nonviable tissue.However,treatment failure and recurrence are common.Recently,adjunctive therapies such as hyperbaric oxygenation have been widely applied in treatment of osteomyelitis to promote sanative effect on osteomyelitis.In this review,we will outline the rationales and current status of potential adjunctive therapies in osteomyelitis management.
