In this study, the modified zeolite with certain hydrophobicity was prepared by modifying natural zeolite by the silane coupling agents such as vinyltrimethoxysilane (VTMO), trimethoxysilane (TMS) and trimethylchlorosilane (TMCS). The modified zeolite has a higher hydrophobicity and adsorption capacity than natural zeolite while ensuring the advantages of natural zeolite, which is more conducive to the adsorption of organic pollutants from aqueous solution. The adsorption experiment on naphthalene in aqueous solution shows that the modified zeolite has a stronger adsorption capacity. In the adsorption thermodynamics experiment, the isothermal adsorption models such as Freundlich and Langmuir can better describe the adsorption of naphthalene on modified zeolite, but the isothermal adsorption model Freundlich has a higher correlation. At 303K, the static adsorption capacity is 339μg/g. The kinetic analysis shows that the adsorption of naphthalene on modified zeolite conforms to the quasi-second order kinetic model.

微生物燃料电池(MFC)是利用生物催化剂将污水有机物中的化学能直接转化为电能的技术,因其功率密度和能量转化效率低,电极制作成本高,限制了其大规模实际应用。因此如何提高电极的催化性能并降低电极制作成本成为MFC的研究重点方向。由于石墨烯基杂化材料具有良好的导电性和催化特性,因此石墨烯基杂化材料成为在MFC电极应用中的热点之一。本文综述了近年来MFC石墨烯基杂化电极材料的最新研究进展,重点讨论了改性石墨烯电极、金属及非金属/石墨烯杂化电极、金属氧化物/石墨烯杂化电极、聚合物/石墨烯杂化电极和石墨烯凝胶电极的设计思路和制备方法及其催化性能,着重分析了石墨烯基阳极和阴极杂化材料对MFC产电性能的影响。最后对石墨烯基杂化材料在MFC应用中存在的问题及研究前景进行了总结和展望。

Background Treatment of extensive post-traumatic composite bone and soft tissue defects remains a complicated therapeutic problem and a challenge for surgeons. We investigated the application of local flaps and Ilizarov osteogenesis in the reestablishment of severe combined defects of tibial bone and soft tissue. Methods Sixteen patients with bone and soft tissue defects were included. The mean age of the patients was 31.5 years. The average time from injury to initial surgery was 14.4 weeks. The average soft tissue and bone defect sizes were 92.9 cm2 and 8.7 cm, respectively. Local flaps were created to reconstruct the soft tissue defects. The Ilizarov external fixator or the Orthofix Limb Reconstruction System was used to reconstruct bony defects using delayed distraction osteogenesis. Results Two myocutaneous flaps and 14 reverse island flaps were applied. All transferred flaps survived. Fifteen patients healed with equal leg length, and one healed with a residual leg-length discrepancy of 1.5 cm. One patient with an Ilizarov external fixator developed ankle joint stiffening and a pin-track infection that was successfully treated with oral antibiotics. No patient developed pin loosening. All patients walked without assistance. Fifteen patients returned to their work, and one lost her job. The results were evaluated using the Paley bone and functional assessment scores. The bone assessment results were excellent in 14 and good in two patients. Functional assessment scores were excellent in 13, good in two, and fair in one patient. Conclusion The combination of local flaps and sequential distraction osteogenesis can be used for successful reconstruction of defects of incorporated bone and soft tissue.

Background A virtual reality simulator provides a novel training model for improving surgical skills in a variety of fields. They can simulate a variety of surgical scenarios to improve the overall skills required for endoscopic operations, and also record the operative process of trainees in real-time and allow for objective evaluation. At present, some simulators for transurethral resection of the prostate （TURP） are available. The utility of virtual reality simulators in training of transurethral prostatectomy was investigated. Methods Thirty-eight urologists were randomly selected to take part in a simulation based training of TURP using the TURPSimTM system. Pre and post-training global rate scale （GRS） scores and objective parameters recorded by the simulator were assessed. Then, questionnaires were filled out. Results Compared with baseline levels, the GRS scores of trainees increased （18.0±4.0 vs. 12.4±4.2, P 〈0.001）, while the rate of capsule resection （26.3%±0.6% vs. 21.2%±0.4%, P 〈0.001）, amount of blood loss （（125.8±86.3） ml vs. （83.7±41.6） ml, P 〈0.001）, external sphincter injury （3.6±2.9 vs. 2.0±2.0, P 〈0.001 ） decreased significantly after training. Most trainees were satisfied with the simulator based training and believed that the simulator accurately mimicked actual surgical procedures and could help improve their surgical skills. Conclusions As a new method of training on transurethral prostatectomy skills, training of TURP using a virtual simulator can help urologists improve their surgical skills and safety. Therefore, the application of the TURPSimTM system in education and training of urologic surgery is warranted.

Biodiversity research increasingly relies on distribution networks for dealing with large-scale primary data. Up-to-date information on biodiversity is critical for the proper management and conservation of any area. The first step towards conservation should be to compile an authoritative species inventory or checklist. Catalogue of Life:Higher Plants in China(CNPC) is an ongoing biodiversity informatics project with the aim to integrate existing higher plants inventory data, and provide access via an internet based web service to public user and the scientific community. The CNPC, for the first time, provides integrated and authoritative taxonomic information on higher plant species found in China, and this database will be permanent, free and continously updated. Presently,a total of 34 377 species have been included in the database. Among of them,16 620 species are only found in China. Taxa are classified into 432 families and 3 941 genera. The CNPC will be an important source for scientists working on Chinese flora, and will play an important role in helping to achieve the targets set under the Global Strategy for Plant Conservation in the future

The role of late embryogenesis abundant （LEA） proteins in stress tolerance was examined by using a yeast expression system. LEA protein tolerance to the abotic stresses in plants involved in salt, drought and freezing stresses and additional tolerance to heat, NaHCO3 （salt-alkali） and ultraviolet radiation was also investigated. The transgenic yeast harboring the Tamarix LEA gene （DQ663481） was generated under the control of inducible GAL promoter （pYES2 vector）, yeast cells transformed with pYES2 empty vector were also generated as a control. Stress tolerance tests showed that LEA yeast transformants exhibited a higher survival rates than the control transformants under high temperature, NaHCO3, ultraviolet radiation, salt （NaCl）, drought and freezing, indicating that the LEA gene is tolerant to these abiotic stresses. These results suggest that the LEA gene is resistant to a wider repertoire of stresses and may play a common role in plant acclimation to the examined stress conditions.
