[Objective]A new limited contact femoral supracondylar interlocking intramedullary nail(LCFSIIN) was made,which was part of a new custom-made hemi-knee joint,to improve the results of childrens' limb salvage.[Method]A new LCFSIIN was performed and the stress of bolts,intramedullary nails and bone were analyzed by finite dement analysis(FEA) while the bolts were implanted in different angulafions-0?,15?,30?,45?and 60?.[Result]The results of FEA show that the stress of bolts,bone and nails with 15? insertion angles of bolt was the tiniest and well distributed.Stress of bone with 0? insertion angles was more obvious than that with 15?,30?and 45?.The more the angles,the stress of proximal bolt became more obvious and the stress of distal bolt decreasing.[Conclusion]This new LCFSIIN can reduce destruction of biological environment of bone and is easy in use in limb salvage surgery of allograft.

Objective To investigate the expression of insulin-like growth factor-Ⅱ( IGF-II ) and its mRNA in human placenta and to evaluate its role in the pathogenesis pregnancy induced hypertension (PIH). Methods The cellular distribution of IGF-Ⅱin normal and PIH placenta was determined by immunohistochemistry. Trophoblasts were digested,separated,and purified from placenta. IGF-ⅡmRNA expression in trophoblasts was detected by RT-PCR. The mean density was determined by image analysis technique. Results (1) IGF-Ⅱwas mostly found in syncytiotrophoblast,cytotrophoblast and amnio-chorion. The strongest immunoreactivity was observed in the syncytiotrophoblast and cytotrophoblast. (2)The mean density of PIH placenta (0.324?0.042) was significantly lower than that of normotensives (0.360?0.072,P

There is immense interest in the long-chain polyunsaturated fatty acids(LC-PUFAs) on account of their health-beneficial properties.There has been considerable interest in the production of LC-PUFAs in transgenic plants to provide a cheap,sustainable and clean source of these fatty acids.Several main LC-PUFAs,their roles and metabolic pathway in plant are introducedbriefly,progresses on biosynthesis of LC-PUFAs in transgenic plant are reviewed,and strategies for improving the yields of LC-PUFAs in plant are also discussed.

Many unusual fatty acids present in the seed oils of non-food plants are modified at the ?12 position either by the addition of epoxy or hydroxy groups or by the formation of triple (acetylenic) bonds or conjugated double bonds. The introduction of these functionalities into C18 fatty acids is catalyzed by a family of divergent forms of the fatty-acid ?12-desaturase (FAD2) enzyme. Genes encoding these enzymes have now been cloned from a variety of organisms and expressed in transgenic oilseeds. However,the accumulation of the intended fatty acids in transgenic plants has been relatively disappointing,and the mechanisms of these unusual fatty acids biosynthesis and transferring from phosphatidylcholine into storage triacylglycerols still need to be elucidated.

The evolution of the quality control concepts of medical products within the global context and the development of the quality control technology of Chinese medicine are briefly described. Aimed at the bottlenecks in the regulation and quality control of Chinese medicine, using Big Data technology to address the significant challenges in Chinese medicine industry is proposed. For quality standard refinements and internationalization of Chinese medicine, a technological innovation strategy encompassing its methodology, and the R&D direction of the subsequent core technology are also presented.

Objective:This study aims to investigate the method and clinical outcomes of feeding tube placement and periopera-tive nutritional support for esophageal carcinoma patients. Methods:A total of 513 esophageal carcinoma patients who have undergone radical resection and reconstruction by a single operating group between January 2012 and December 2013 participated this study. Feed-ing tubes were inserted via the nasal path of 497 cases and by jejunostomy in 16 cases. Early enteral nutrition (EN) was administered through the feeding tubes 24 h postoperatively with a stepwise increase, whereas supplementation of parenteral nutrition (PN) was ter-minated until total EN. Results:Feeding tubes were successfully inserted in all patients during operation. No death or nutritional and metabolic disorders were documented during the observation period. No differences in anastomotic fistula, pulmonary complication, and incision infection were identified between the nasointestinal and jejunostomy groups (P>0.05). A higher incidence of intestinal ob-struction was observed in the jejunostomy group than in the nasointestinal group (P<0.05). Conclusion:Effective placement of nasoin-testinal tube and early enteral feeding are safe and effective methods for patients who have undergone esophagectomy for esophageal carcinoma.
