厦门沿海的砂壳纤毛虫(原生动物,纤毛门,砂壳目)

对厦门沿海6个代表性站位砂壳纤毛虫进行了为期1年的采集,共分离鉴定了27种砂壳纤毛虫,其中拟铃虫属Tintinnopsis 20种,薄铃虫属Leprotintinnus 3种,类铃虫属Codonellopsis 2种,领细壳虫属Stenosemella 1种以及网纹虫属Favella 1种。对该5属27种砂壳纤毛虫进行形态学描述,并提供了显微照片,其中侧胀拟铃虫Tintinnopsis ventricosoides Meunier,1910为中国新记录种。国家自然科学基金(91751207和41306125);;海洋公益性行业科研专项经费(201505003-3);;中海石油有限公司项目(CNOOCKJ125FZDXM00TJ001-2014,CNOOC-KJ125FZDXM00ZJ001-2014)资助~

Clinical analysis of anti-N-methyl-D-aspartate receptor encephalitis patients with cerebellar ataxia

摘要：&nbsp;目的:分析总结合并小脑共济失调的抗N-甲基-D-天冬氨酸受体（NMDAR）脑炎患者的临床特点。方法:回顾分析北京协和医院2011&mdash;2019年诊治的抗NMDAR脑炎患者中合并小脑共济失调患者的临床表现、实验室检查结果、治疗与预后。结果:347例抗NMDAR脑炎患者中共有15例（4.3%）合并小脑共济失调，其中1例患者合并卵巢畸胎瘤，男性7例，女性8例，中位年龄28岁，从脑炎发病到出现小脑症状平均病程30.8 d，极期改良Rankin量表（mRS）评分平均3.73分，脑脊液白细胞中位数28&times;10 6/L。15例患者均接受了一线免疫治疗，1例患者接受了利妥昔单抗二线免疫治疗，9例患者接受了吗替麦考酚酯长程免疫治疗。随访时间7~66个月，末次mRS评分平均2.73分，预后良好者（mRS评分&le;2分）6例（6/15） 。结论:抗NMDAR脑炎合并小脑共济失调者相对少见，此类患者在神经功能方面预后较差，应及时识别抗NMDAR脑炎患者的小脑共济失调症状，采用规范的免疫治疗方案和长程免疫治疗，以期改善预后。</p

Shift of Economic Emphases of China's Eastern,Central and Western Regions——A Comparative Study

将我国分为东、中、西3大区域,分别分析其1995~2010年经济重心的演变轨迹,分析显示东部地区经济重心先南移后北移,中部呈现“南—北—南“趋势,而西部经济重心则持续北移,并据此趋势预测未来演变态势。强调加快西部地区南部省区的建设,深入分析拉动gdP增长的“三驾马车“对3大地区的不同影响,为缩小地区经济差距及协调区域发展提供理论依据。Considering the three parts of China,the eastern,central and western regions,this paper studies the shift trends of economic emphases in these areas during 1995—2010.It is shown that the emphasis of the eastern region moved from north to south and then turned back to the north again,while the central region followed a south-north-south pattern,and the western region showed a persistent northward trend.Based on these observations,forecasts of the future trend can be made.It is stressed that development of the south provinces in the western region must be speeded up.Effects of the "three demands" on the growing GDP are analyzed,and a theoretical foundation is laid for narrowing the inter-regional differences and promoting the economical progress of all regions

Recent Biotechnological Applications of Glyco-Nanomaterials

Thanks to the chemically tunable sizes and physical (e.g. electronic, photonic and magnetic) properties, nanomaterials are recently being applied as imaging agents or spectroscopic tools to monitor cellular or biological systems. However, unfunctionalized nanomaterials have a perceived, potential risk of cytotoxicity and a typical lack of cell-specific function. Given the distinct roles of glycans in nature, aqueous solubility/dispersability, biocompatibility, and as endogenous ligands, the properties of nanomaterials can be improved and directed by constructing glycosylated hybrids. In this mini-review, recent developments of glyco-nanomaterials including carbon-based nanomaterials, magnetic nanoparticles, and gold nanoparticles will be discussed. © 2011 American Chemical Society

20世纪90年代LUCC过程对中国农田光温生产潜力的影响——基于气候观测与遥感土地利用动态观测数据

在20世纪90年代中国气候观测数据和遥感土地利用动态观测数据的支持下,计算了中国20世纪90年代农田光温生产潜力的变化.结果表明:20世纪90年代的LUCC过程直接导致了中国农田光温生产潜力总量和区域分布的变化,总体趋势是南减北增,总量净增加2622万吨;在各种土地利用类型之间的相互转变和转化过程中,耕地扩张和农田损失是导致全国农田光温生产潜力总量净变化的主要原因,耕地扩张使全国农田光温生产潜力总量净增加8335万吨,占全国农田光温生产潜力总量的3.50%,主要分布在东北、西北和华北等农林、农牧交错区和沙漠绿洲区,主要是由于该地区大面积的农田开垦所导致;农田损失使全国农田光温生产潜力总量净减少5713万吨,占全国农田光温生产潜力总量的2.40%,主要分布在黄淮海平原、长江三角洲、珠江三角洲、陇中、东南沿海、四川盆地东南部以及乌鲁木齐—石河子一带,主要是由于该区域经济发展较快,城市扩张明显,城乡建设用地大量侵占耕地的缘故
