杏仁对环磷酰胺和3－甲基胆蒽诱变性的抑制效应

本文以小鼠细胞ＳＣＥ和微核率为指标评价了杏仁对抗肿瘤药环磷酰胺和遗传毒物３－甲基胆蒽诱变性的抑制效应，发现中药杏仁无致突变性，而且，对上述两种强诱变剂均有抑制作用。实验结果说明杏仁对突变具有一定和防护作用，并提示杏仁有望成为肿瘤化疗药物毒副作用的拮抗剂。

Multiple ionization of atom clusters by intense soft X-rays from a free-electron laser

Intense radiation from lasers has opened up many new areas of research in physics and chemistry, and has revolutionized optical technology. So far, most work in the field of nonlinear processes has been restricted to infrared, visible and ultraviolet light, although progress in the development of X-ray lasers has been made recently. With the advent of a free-electron laser in the soft-X-ray regime below 100 nm wavelength, a new light source is now available for experiments with intense, short-wavelength radiation that could be used to obtain deeper insights into the structure of matter. Other free-electron sources with even shorter wavelengths are planned for the future. Here we present initial results from a study of the interaction of soft X-ray radiation, generated by a free-electron laser, with Xe atoms and clusters. We find that, whereas Xe atoms become only singly ionized by the absorption of single photons, absorption in clusters is strongly enhanced. On average, each atom in large clusters absorbs up to 400 eV, corresponding to 30 photons. We suggest that the clusters are heated up and electrons are emitted after acquiring sufficient energy. The clusters finally disintegrate completely by Coulomb explosion.     

Structures of Textile-apparel Supply Chain： Concepts and Cases

In recent years, supply chain management （SCM） has been in popularity as a new management philosophy for all industries, including textile and apparel industries. The textile-apparel supply chain is relatively complex because it encompasses many participants such as yarn manufacturers, fabric manufacturers, garment manufacturers and retailers. Although many scholars are engaged in researching SCM in textile and apparel industries, a systematic classification of textile-apparel chain does not exist. The paper proposes three types of textile-apparel chain, nominated vertical integration chain, traditional sourcing chain and 3P-hub （third party as the hub） chain. Different coordinators exist in different types of chain. Three Hong Kong headquartered companies, Esquel Group, TAL Apparel Ltd., and Li ＆ Fang （Trading） Ltd. are used as cases responding to each type of the structures respectively.     

新型双层皮肤组织工程支架的构建

模拟天然皮肤的真、表皮结构,以胶原和壳聚糖为主要原料构建皮肤组织工程双层支架.将固含量0.8%(mass)的胶原-壳聚糖溶液冻干后压膜,经戊二醛交联后再冻干形成双层支架的底层,然后注入固含量0.2%(mass)的胶原-壳聚糖溶液,经冻干、交联、再冻干即得结构较稳定的双层复合海绵支架.在双层支架上培养的小鼠成纤维细胞贴壁生长正常.本研究构建的胶原-壳聚糖双层支架具有良好的结构稳定性和细胞相容性.     

新疆西天山西段金铜成矿带——中亚成矿域东延

新疆西天山西段位于哈萨克斯坦 -伊犁板块的东南部边缘 ,包括伊犁石炭纪裂谷、那拉提地块、哈尔克早古生代被动陆缘褶皱带。主要已知矿床 (点 )按其容矿围岩可分为镁铁 -超镁铁岩型、斑岩型、花岗岩型、矽卡岩型、陆相火山岩型、陆相沉积岩型、浅变质含碳碎屑岩型。根据区内成矿地质条件、矿化特征 ,区内以找金矿主 ,兼顾铜镍矿等。金矿以穆龙套型和火山岩型金矿为主 ,同时注意卡林型和中 -酸性侵入岩内外接触带型 ;铜矿以镁铁 -超镁铁岩型和火山岩型为主。地质与成矿条件与中亚成矿域具有可比性 ,因此 ,新疆西天山西段金铜成矿带应为中亚成矿域东延部分
