Objective: Maxillary and mandible fractures are severe intermaxillary injuries,frequently involving other vital organs,and usually difficult to be treated.This study discusses the treatment of maxillary and mandible fractures.Methods: We retrospectively analyzed the clinical data of 39 cases of maxillary fractures and/or mandible fractures.Results: Of the 39 cases,34 males,5 females and 84.64% aged from 20 to 50,87.17% were caused by vehicle accidents,and 94.87% were accompanied by injuries of other parts of the body.After surgical treatment,78.95% gained normal or basically normal ocular esthetic results and 68% achieved good or improved facial esthetic results.Conclusion: The results of treatment are closely related with the type and severity of fracture and the time and plan of treatment.Preoperative CT scanning and facial profile three-dimensional reconstruction are necessitated for a thorough evaluation of the fractures and an analysis of the causes and extent of facial and ocular changes.The best treatment plan for maxillary and/or mandible fractures would include anatomic reduction by surgery,intermaxillary elastic traction and rigid internal fixation with the Ti plate.

Objective To understand the air microorganisms pollution and the community structure and distribution characteristics of outdoor airborne microbes in Xi'an in autumn.Methods Airborne microbes were sampled by fallen plates method in autumn,2006 in Xi'an at three typical sites,factories region,garden greenbelt region and main traffic region.Results The results showed that the total concentration of airborne microbes at the factories region and garden greenbelt region,main traffic region was 2 500 cfu/m~3,1 354 cfu/m~3 and 4 404 cfu/m~3 respectively.Bacteria and fungal genus were predominant.Gram positive bacteria were much more than Gram negative bacteria.There were 20 genera of bacteria and 8 fungal genus were detected. Micrococcui,Bacillus,Staphylococcus and Pseudornonus were predominant.The most frequently isolated fungal genus were Penicillium,Paecilomces,Cladosporium and Nonsporulatiny mycelia.The community structure of airborne fungal genus and the dominant genus in different function region was significantly different.The distribution characteristic of airborne microbe concentration in different function region was different.The concentration of airborne bacteria was significantly lower in garden greenbelt region than factories region and main traffic region,whereas the concentration of airborne fungi in garden greenbelt region was higher than that in factories region and main traffic region.Conclusion The distribution of the airbome microbes shows a characteristic of time and space,it is affected not only by the environment and pollution,but also by the other factors such as human activities,animals and plants.

Background Optic neuritis is closely associated with multiple sclerosis (MS).Its pathogenesis is uncompletely clear,and less basic researches are carried out at home and abroad. Objective This study was to reveal the expression of myelin basic protein (MBP) in the optic nerve of rat with experimental allergic encephalomyelitis (EAE) and to provide a theoretical evidence for the research of the relationship of optic neuritis with MS. Methods Fifty clean Wistar rats were randomized into the control group and immune 8,12,18 and 25 days groups.Myelencephalon was collected from 5 guinea pigs to prepare the homogenate and mixed with the isovolumetric complete Freud' s adjuvant (CFA).The 0.5 ml mixed antigen emulsifier was subcutancously injected into the 4 maps together with Bordetella pertussis 0.2 ml under the cutancous of dorsalis pedis at 0 and 48 hours to induce the EAE.Behavior of the rats was evaluated to score the neurological function.The optical nerve sections were prepared 8,12,18 and 25 days after immunology for the histopathological examination,and immunochemistry and Western blot were used to detect the expression of MBP in optic nerve.The use of the animals complied with the Regulation for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission. Results The disorder of motor nerve was seen 12 days following the immune,and the clinical neural functional scores were significantly higher 12 day and peaked on 18 days myelination and then gradually reduced.The histopathological examination showed that the irregular alignment of neural fiber was found at 12 days,and changes of cellular structure,edema of neural shaft bunch were observed at 18 days.However,the abnormal cells were significantly less 25 days following the immune.Immunochemistry showed that the MBP was expressed mainly in the myelination of optic nerve fibers.The numbers of positive cells for MBP were (115.75±26.49)cells/5 fields at the 12th day,showing a significant lowing in comparison with (167.44±22.49)cells/5 fields of control group (t=4.537,P＜0.05 ).The positive cells were lest at the 18th day with the values ( 75.57 ± 34.54) cells/5 fields ( t =6.362,P＜0.01 ).At the 25th day,positive cells increased to ( 117.63 ± 13.78) cells/5 fields,which still was lower than those of the control group ( t =4.068,P＜0.05 ).Western blot assay illuminated that with the prolong of immune time,MBP/β-actin ratio in optic nerve was gradually reduced and followed the same pattern at the 12th day( t =4.639,P＜0.05 ).At 18 days after immune in comparison with the control group,the expression of MBP/β-actin ratio in optic nerve was the least (t=8.427,P＜0.01). Conclusions MBP can be degraded in rat optic nerve.This is a further evidence that optic neuritis is a severe demyelination disease.It is clearly related to MS.

Immobilized penicillin acylase was used for bioconversion of penicillin G into 6-APA in aqueous two-phase systems consisted of a light-sensitive polymer PNBC and a pH-sensitive polymer PADB.Partition coefficients of 6-APA was found to be:about 5.78,in the presence of 1% NaCl.Enzyme kinetic showed that reaction reached equilibrium at 7h or so.The 6-APA mole yields were 85.3%(pH 7.8,and 20 ℃) and this value was about 20%higher than control in reaction of single aqueous phase buffer.Partition coefficient of penicillin G(Na) washardly changeable,while partition coefficient of product,6-APA and phenylacetate acid was significantly changeable.Reason is due to Donnan effect of phase systems andhydrophobicity of products.The change of partition coefficients of products also affects bioconversion yield of products.In the aqueous two-phase systems,substrate,penicillin G,products 6-APA and phenylacetate acid are biased in top phase,while immobilized penicillin acylase is completely partitioned in bottom.Substrate,penicillin G enters into bottom phase,and it is catalyzed into 6-APA and phenylacetate acid,then the products enter into top phase.Finally,inhibition of substrate and products is removed to result in improvement of products yield.Moreover,immobilized enzymehashigher efficiency than immobilized cells and occupy smaller volume.Comparing with free enzyme,immobilized enzymehashigher stability,longer use life,completely partitioned in bottom phase and recycle.Bioconversion in two-phase systems using immobilized penicillin acylase showed outstanding advantage.The light-sensitive copolymer forming aqueous two-phase systems could be recovered by laser radiation at 488 nm or filtrated 450 nm light,while pH-sensitive polymer PADB could be recovered by isoelectric point(pH 4.1).The recovery of the two copolymers was 95%~99%.

In industrial glutamate fermentation, intermitted feeding glucose with the help of off-line glucose measurement is generally necessary. This kind of feeding strategy could cause large variations in glucose concentration so that it is not favorable for the achievement of efficient and stable glutamate fermentation. Glutamate fermentation is characterized with typical non-growth association behavior, and during glutamate production phase glucose consumption is closely correlated with ammonia consumption. In this study, glucose concentration was controlled at various pre-determined levels by predicting glucose consumption amount and thus its concentration with the aid of on-line monitoring ammonia consumption. When glucose concentration was controlled around a lower level of 5 g/L~10 g/L, the final glutamate concentration could reach a relatively higher level of 80 g/L. In this way, the huge osmotic stress change due to the large glucose concentration variation with the intermitted feeding method could be avoided and the glutamate fermentation performance enhancement be expected.
