OBJECTIVETo investigate effects of elastic stable intramedullary nails for the treatment of radial neck fracture in children.
METHODSFrom July 2006 to December 2011, 25 children with radical neck fractures, which included 16 males and 9 females aged from 7 to 15 years old (means 10.7), were treated with elastic stable intramedullary nails. According to Judet classification, 6 cases were type II, 17 cases were type III and 2 cases were type IV (including 1 case with type IVa and 1 case with type IVb). The fracture healing, pain, deformity and range of motion of elbow were recorded.
RESULTSAll patients were followed up for 6 to 24 months with an average of 14 months. Twenty-five patients were obtained bone healing. According to Tibone and Stoltz evaluation standard, 18 cases got excellet results, 4 cases in good and 3 cases in moderate.
CONCLUSIONElastic stable intramedullary nails for the treatment of radial neck fracture in children has advantages of simple operation,less trauma and good results.

Corynebacterium glutamicum SA001 is a mutant with lactate dehydrogenase (ldhA) deletion. In order to increase metabolic flux from isocitrate to succinate, and to improve the production of succinate under anaerobic conditions,we transducted the gene aceA coding isocitrate lyase (ICL) from Escherichia coli K12 into Corynebacterium glutamicum SA001 (SA001/pXMJ19-aceA). After 12 h aerobic induction by adding 0.8 mmol/L of IPTG, the recombinant strain was transferred to anaerobic fermentation for 16 h. Succinate reached 14.84 g/L, with a productivity of 0.83 g/(L x h). Compared to C. glutamicum SA001, the activity of ICL of the recombinant strain was increased 5.8-fold, and the succinate productivity was increased 48%. Overexpression of isocitrate lyase will increase the metabolic flux of glyoxylate bypass flowing to succinate.

Objective To investigate the mechanisms of inhibitory effect of Erlotinib,an epidermal growth factor(VEGF) receptor inhibitor,on angiogenesis of pancreatic carncer.Methods①In a tube formation assay,Erlotinib(100?mol/L) was applied to the culture media and compared to the serum free media.The expression of vascular endothelial growth factor(VEGF) in BxPC-3 cells treated with Erlo- tinib at different concentrations(5,50,100,200?mol/L) was determined by RT-PCR.②The xeno grafts derived from BxPC 3 cancer cells were inoculated into the BALB/C nude mice.The mice were treated with either Erlotinib(100 mg/kg of Erlotinib oral lavage daily) or saline for four weeks.The vol- ume of the xenografts was measured and the tumor growth rate was calculated.The microvessel density (MVD) of tumor tissue was determined by immunohistochemistry with an antibody against factorⅧ. Results There were less endothelium cells and close hollow tubular structures in grlotinib treated group compared to the control group in the tube formation assay.The mean weight of xenografts in Erlotinib treated group[(0.397?0.550)g] was significantly lower than that in the control group[(1.570?1.060)g] with a inhibitary rate of 74.5%.The expression of VEGF mRNA in Ertotinib treated groups (=50?mol/L) were decreased comparing to the control group.The VEGF expression in xeno- grafts tumor tissues was also markedly down-regulated.The MVI) was significantly decreased in Erlotinib treated group( 1.86?0.43)than that in the control group (5.98?1.27,P

BACKGROUND:Compared with hydroxyapatite materials and other nano-hydroxyapatite composites, carbon fiber-reinforced nano-hydroxyapatite/polyamide 66 composites have been significantly improved in the mechanical strength, toughness, elastic modulus and other aspects. It can be used for repairing bone defects of loading parts. OBJECTIVE:To investigate the biocompatibility of carbon fiber-reinforced nano-hydroxyapatite/polyamide 66 composites in bone tissues. METHODS:Eight Bama mini pigs were taken to establish models of thoracic vertebral defects and implanted with carbon fiber-reinforced nano-hydroxyapatite/polyamide 66 composites. At 8, 16 and 24 weeks after implantation,the animals were sacrificed, respectively, for bone mineral density detection and hematoxylin-eosin staining. Blood samples for kidney and liver function tests were taken before and 1 and 8 weeks after implantation. RESULTS AND CONCLUSION: Hematoxylin-eosin staining of bone samples showed that the materials could bond with the bone defect interface without rejection, and could induce osteogenesis of chondrocytes. At 8 weeks after surgery, the broken ends of cancelous bone closed and the composite material was wrapped by granulation tissues. At 16 weeks after surgery, granulation tissues were organized and new bone developed directly from fibroblast cels. The new bone tissues were nearly fused with the end of cancelous bone. At 24 weeks after surgery, new bone tissue became mature lamelar bone, and the end of cancelous bone was connected tightly with the composite material. Bone mineral density of the implanted vertebra showed an increase trend at 8, 16 and 24 weeks after implantation. Over time, the bone mass was increased. The liver and kidney function tests showed that there was no significant difference before and after implantation. It is preliminarily believed that the carbon fiber-reinforced nano-hydroxyapatite/polyamide 66 composite has excelent histocompatibility and bioactivity without hepatic toxicity and nephritic toxicity.
