作者： Yong Zhou jian Lin Xiaoqiang Zhang Lixin Xu Chun Gu Biao sun Anting Wang Qiwen Zhan Department of Optics and Optical Engineering University of Science and Technology of China Electro-Optics Program University of Dayton

We demonstrate an all fiber passively mode-locked laser emitting a radially polarized beam by using a few-mode fiber Bragg grating to achieve mode selection and spectrum filtering. An offset splicing of single-mode fiber with four-mode fiber is utilized as a mode coupler in the laser cavity. Carbon nanotubes are introduced into the laser cavity as the saturable absorber to achieve self-start mode locking. The laser operates at 1547.5 nm with a narrow spectrum width of 0.3 nm at 30 d B. The emitted mode-locked pulses have a duration of 22.73 ps and repetition of10.61 MHz. A radially polarized beam has been obtained with high mode purity by adjusting the polarization in the laser cavity.

以处理量为1 800 m3/h的亚硫酸钠循环法烟气脱硫装置为实验对象,着重研究吸收液pH值、液气比L/G、吸收液成份和脱硫剂初始浓度等因素对脱硫效率的影响,并对脱硫剂再生过程和再生清液的脱硫特性进行研究.结果表明:吸收液pH值决定硫成份在溶液中的状态,从而影响脱硫效率,当pH>6时,脱硫效率高且随pH增大变化平缓;当pH90%);同等条件下,与NaOH和Na2CO3相比较,Na2SO3的脱硫能力稍低;吸收液Na2SO3浓度在5%～10%范围内脱硫效率大于90%;脱硫剂再生反应过程能很快完成,再生脱硫剂脱硫效率稳定,与新鲜脱硫剂相比脱硫效率略低.

BACKGROUND： With the age growing, changes of behavioral problems in children whose parents had schizophrenia, differences of related factors and ways for particular intervention should be further studied. OBJECTIVE： To survey the behavioral problems in children of different aged patients with chizophrenia and investigate the correlation between behavioral problems and related factors in different aged groups. DESIGN： Cross-sectional study. SETTING： Shandong Mental Health Center. PARTICIPANTS： A total of 364 patients with schizophrenia were selected from eleven psychiatric hospitals from June 1999 to June 2000. There were 179 males and 185 females, and their ages ranged from 28 to 45 years. All patients met modified diagnostic criteria of schizophrenia （the second edition）, China Classification of Mental Diseases and Diagnostic Criteria. Meanwhile, children of the 364 patients were grouped based on their ages, including 6 - 1 l years old group [n -217; 114 males and 103 females; mean age of （9±2） years] and 12 - 16 years old group [n = 147; 99 males and 48 females; mean age of （14±1） years]. The Chinese norms of Achenbach＇s Child Behavior Check List were regarded as the normal control group. METHODS： Children who received self-made mental health related factors inventory and Achenbach＇s Child Behavior Check List were involved in this study. All children and their parents provided the confirmed consent. Achenbach＇s Child Behavior Check List was used for parents to mainly evaluate children, and the results manifested various behavioral problems based on different sexes and different ages. Self-made mental health related factors inventory contained questionnaires for parents and children, respectively. In this study, home situation of parents as well as personality characteristics and educational styles of children were mainly evaluated. MAIN OUTCOME MEASURES： ① Scores of Achenbach＇s Child Behavior Check List in different aged children; ② Scores of self-made

作者：张峤张健单莉新疆医科大学附属肿瘤医院胸部肿瘤科新疆乌鲁木齐830011 中国人民解放军69260部队卫生队新疆乌鲁木齐830002

目的:探究miR-142-5p靶向转录因子YY1调控上皮间质转化(epithelial-mesenchymal transition,EMT)抑制非小细胞肺癌(non-small cell lung cancer,NSCLC)细胞体外转移的机制。方法:qRT-PCR检测肺癌细胞系中YY1和miR-142-5p表达水平;利用生物信息学软件预测并通过双荧光素酶报告基因实验验证miR-142-5p与YY1的结合位点;Transwell实验和划痕愈合实验分析YY1和miR-142-5p过表达对肺癌细胞迁移、侵袭的影响;Western blot与qRT-PCR检测各组细胞内EMT相关蛋白的表达变化。结果:YY1在不同肺癌细胞系中均表达上调,miR-142-5p表现为表达下调;双荧光素酶报告基因实验结果进一步验证了YY1与miR-142-5p的靶向结合相关性;抑制miR-142-5p表达水平能显著提高细胞中YY1表达,而miR-142-5p过表达能显著抑制肺癌细胞中YY1的表达水平,两者表达水平呈负相关;Transwell和划痕实验表明,YY1过表达能够促进肺癌细胞转移,而miR-142-5p过表达会抑制肺癌细胞转移;YY1过表达促进EMT相关蛋白的表达,而miR-142-5p作用相反。结论:miR-142-5p负向调控YY1作用于EMT相关分子表达,进而在体外抑制NSCLC细胞的转移。
