Liquid phase epitaxy （LPE） is a mature technology. Early experiments on single magnetic crystal films fabricated by LPE were focused mainly on thick films for microwave and magneto-optical devices. The LPE is an excellent way to make a thick film, low damping magnetic garnet film and high-quality magneto-optical material. Today, the principal challenge in the applied material is to create sub-micrometer devices by using modern photolithography technique. Until now the magnetic garnet films fabricated by LPE still show the best quality even on a nanoscale （about 100 nm）, which was considered to be impossible for LPE method.

作者： HUANG yu-juan wu Yi-long XIE Song-xi YANG Jing-ji HUANG Yi-sheng LIAO Ri-qiang Department of Lung Cancer Cancer Center Guangdong Provincial People＇s Hospital Guangzhou 510080 China

Background Conventional treatment for non-small cell lung cancer （NSCLC） brain metastases （BM） is whole-brain radiotherapy （WBRT）. The efficacy is limited. It might be increased by a potent radiosensitizer such as gemcitabine, which is believed to cross the disrupted blood-brain barrier. The primary objective of this study was to determine the maximum tolerated dose （MTD） of weekly gemcitabine given concurrently with WBRT. Methods Patients with BM from NSCLC were included. The dose of WBRT was 3750 cGy （total 15 times, 3 weeks）. Gemcitabine was given concurrently with WBRT on days 1, 8 and 15. The starting dose was 400 mg/m^2, escalated by 100 mg/m^2 increments. At least three patients were included per level. Dose limiting toxicity （DLT） was defined as grade 4 hematological or grade 2 neurological toxicity. When two or more patients experience DLT, the MTD was reached. Results A total of 16 patients were included; 69% had a performance status （PS） 1 （Eastern Cooperative Oncology Group, ECOG）. A total of 69% had concurrent active extra cranial diseases. All had more than 3 BM. Up to 600 mg/m^2 （level 3） no neurology toxicity was observed. At 600 mg/m^2 two out of 9 patients developed grade 4 thrombocytopenia. One of the two patients＇ thrombocytopenia was confused with disseminated intravascular coagulation （DIC）. At 700 mg/m^2 two out of 4 patients developed neurotoxicities. One developed grade 3 seizure and cognitive disorder. Another patient developed suspected grade 2 muscle weakness. Conclusions The MTD was reached at a dose of 700 mg/m^2. The dose of 600 mg/m^2 would be considered for further study.

Although solar steam generation strategy is efficient in desalinating seawater,it is still challenging to achieve continuous solar-thermal desalination of seawater and catalytic degradation of organic ***,dynamic regulations of hydrogen bonding networks and solvation structures are realized by designing an asymmetric bilayer membrane consisting of a bacterial cellulose/carbon nanotube/Co_(2)(OH)_(2)CO_(3)nanorod top layer and a bacterial cellulose/Co_(2)(OH)_(2)CO_(3)nanorod(BCH)bottom ***,the hydrogen bonding networks inside the membrane can be tuned by the rich surface–OH groups of the bacterial cellulose and Co_(2)(OH)_(2)CO_(3)as well as the ions and radicals in situ generated during the catalysis ***,both SO_(4)^(2−)and HSO_(5)−can regulate the solvation structure of Na^(+)and be adsorbed more preferentially on the evaporation surface than Cl^(−),thus hindering the de-solvation of the solvated Na^(+)and subsequent nucleation/growth of ***,the heat generated by the solar-thermal energy conversion can accelerate the reaction kinetics and enhance the catalytic degradation *** work provides a flow-bed water purification system with an asymmetric solar-thermal and catalytic membrane for synergistic solar thermal desalination of seawater/brine and catalytic degradation of organic pollutants.

目的研究强直性脊柱炎(ankylosing spondylitis,AS)患者的饮食习惯与健康人群的差异,探讨饮食这一环境因素在AS发病中的作用。方法对2014年7月到2015年4月在我科就诊的123例AS患者及年龄、性别匹配的120例健康志愿者进行饮食习惯的现况调查,采用单因素及多因素分析比较AS患者和健康对照人群饮食习惯的差异。根据Bath强直性脊柱炎病情活动指数(BASDAI)将AS患者分为病情活动组(BASDAI>4分)和病情无活动组(BASDAI≤4分),研究病情活动与饮食习惯的关系;根据HLA-B27的表达将患者分为HLA-B27阳性组和HLA-B27阴性组,研究饮食和HLA-B27的交互作用对AS发病的影响。结果 AS患者和健康对照人群之间在饮食口味倾向、主食结构、平均每天高胆固醇食物、每天豆类制品、是否吸烟、饮酒频率等饮食习惯上差异存在统计学意义(P<0.05)。多因素分析发现嗜辣口味、每天适量豆制品摄入、适量饮酒是AS发病的保护因素,每天吸烟是AS发病的独立危险因素(P<0.05)。AS病情活动与饮食习惯无关。HLA-B27阳性的患者在饮食口味倾向、豆制品的摄入、吸烟、饮酒等方面与健康对照人群差异有统计学意义(P<0.05,P<0.01)。结论饮食结构不同可能是AS发病的重要环境因素之一,HLA-B27与饮食习惯对AS发病的影响可能存在交互作用。
