Butyric acid can be used to produce cellulose butyrate fiber and ester derivatives,and to be applied in foodstuffs and perfume industries.Recent researches have found that butyric acid is a preferred carbon source for colonic epithelial cells,and can inhibit histone deacetylase,showing great anticancer potentials.With more and more functions of butyric acid being found and applied in bio-related fields,and with consumer's growing preference to bioproducts,biotechnological production of butyric acid will receive more competence than petroleum-based chemical synthesis.Low product concentration and poor selectivity are presently the main restricting factors.Workers have made considerable progress on more cheep carbon sources,optimization of fermentation process,simplifying downstream processing,and genetic engineering of producing strains.Any achievement on these aspects in the future can contribute to put fermentation of butyric acid into industry.

Geriatrics develops relatively late in medical education, but geriatric medical education is rapidly rising for aggravation of the aging of population.And geriatric medical education is desired of the properties medical sciences, and is also the need of the development itself. Therefore, geriatric medical education should be internationalized, to eventually form distinctive education.

AIMTo demonstrate the protective effect of nitric oxide (NO) on gastric mucosa and its relationship to the acid secretion of parietal cells under stress in rats.

METHODSWater immersion-restraint stress (WRS) model in SD rats was performed. The gastric mucosal ulcer index (UI), NO contents in gastric mucosa and H+, K(+) -ATPase activity of parietal cells were measured. The effects of N(G)-nitro-L-arginine methyl ester(L-NAME) and L-arginine (L-Arg) on the H+, K(+)-ATPase activity of parietal cells and stress-induced gastric mucosal lesion were observed.

RESULTSL-NAME pretreatment decreased NO contents in gastric mucosa, activated H+, K(+) -ATPase activity of parietal cells and aggravated gastric mucosal lesion, whereas L-Arg pretreatment increased NO contents, inhibited H+, K(+) -ATPase activity and significantly ameliorated stress-induced gastric mucosal lesion.

CONCLUSIONEndogenous nitric oxide plays an important role in protecting gastric mucosa from stress-induced lesion by inhibiting H+, K(+) -ATPase activity of parietal cells.

Objective To analyze the sequence of microsatellite and the flanking sequence from four populations of Oncomelania hupensis. Methods We cloned 159 SSR-PCR amplification products of a commonly used primer, (CA)8RY, using O. hupensis genomie DNA as template, and sequenced 82 products Results The sequences obtained were novel O. hupensis genomic sequences but not repeat simple sequence. It was observed that 36 out of 82 clones contained microsatellites between priming sites.The flanking sequences of certain microsatellite were invariant. Both (GA/CT). and (TTAGGG/CCCAA)n were found in four populations of O. hupensis. However, (CAA)n were found only in O. hupensis from Fuqing,Fujian province and (TCTCTG), were found only in O. hupensis from Guichi,Anhui province and (GAA/TTC)n, (CAA/TTG)n, (CAT), were found only in O.hupensis from Puge,Sichuan province. Conclusion The results obtained by SSR-PCR should not be interpreted as the amplification of microsatellite loci, and analytical rules similar to those for Random Amplified Polymorphic DNA should be used. SSR-PCR could not make the most of the priority of microsatellite. It seems better to amplify the microsatellites with the primers designed on the basis of the flanking sequence.

Thermo-therapeutic has been proved to be an effective approach for cancer therapy.This paper introduces a kind of new equipment suitable for liver oncology based on this theory,which uses the RF field as the thermal energy and adopts sequential-delivering technology.Its principle and advantages are introduced in detail.

OBJECTIVETo study the therapeutic efficacy of manipulative reduction and percutaneous pin fixation for the treatment of severely displaced distal tibial fractures in children.

METHODSFrom May 2009 to December 2012,56 children with severely displaced distal tibial fractures were analyzed, who had been treated with manipulative reduction and percutaneous pin fixation. Preoperative fractures were confirmed as severely displaced fractures by X-ray apparatus. There were 33 boys and 23 girls,ranging in age from 3 to 14 years, with an average of 10.1 years. All the fractures were closed without vascular or nerve injuries. According to the bone fracture type, under C-arm fluoroscopy, functional reduction was achieved by manipulative reduction. The fractures were fixed with percutaneous pins. Postoperative X-ray confirmed the functional reduction. Follow-up indexes were recorded: intra-operative and postoperative complications,postoperative radiographic examination, lower extremity length and range of ankle motion. Ankle score system of Teeny was used to evaluate ankle function.

RESULTSAll the patients were followed up, and the duration ranged from 3 to 46 months, with an average duration of 19.4 months. According to the Teeny score standard, 35 patients got an excellent result, 7 good and 3 fair. Pin track reaction was found in 4 cases. The X-ray showed all the fractures healed without shortening deformity or epiphyseal arrest at early stage. All the patients could participate in the normal physical activities, having a normal range of motion and excellent strength of the ankle joint.

CONCLUSIONThe method of manipulative reduction and percutaneous pin fixation is a safe and convenient treatment for severely displaced distal tibial fractures in children. It has several advantages as follow: micro-trauma, tiny tissue damage, firm fixation, and the patients can exercise the function of ankle early, suggesting that it is an effective treatment method.
