Positive and negative HCV RNAstrands of the cultured cells and growth mediawere detected by reverse transcriptase-polymerase chain reaction ( RT-PCR ) eachmonth. Core and NS5 proteins of HCV werefurther tested using immunohistochemical SPmethod and in situ RT-PCR.RESULTS HCV RNA positive strands wereconsistently detected the cultured cells for oneyear. The negative-strand RNA in LCL cells andthe positive-strand RNA in supernatants wereobserved intermittently. Immunohistochemicalresults medicated expression of HCV NS3 and Cproteins in LCL cytoplasm mostly. The positivesignal of PCR product was dark blue and mainlylocalized to the LCL cytoplasm.

7曹雪涛院士科研团队论文荣膺中国百篇最具影响国际学术论文--长链非编码RNA1nc-DC通过STAT3调控人DC的分化和功能显示文摘树突状细胞(DC)是免疫系统中重要的抗原提呈细胞,其成熟和功能状态决定着免疫应答的走向和强度。哺乳动物基因组能够转录产生大量的长链非编码RNA(long noncoding RNA,IncRNA),其在免疫系统中的功能还知之甚少。 曹雪涛院十科研团队王品副教授课题组采用了转录组芯片二代测序高通量筛选方法、RNA-pulldown、ChIP-seq等技术展开了对IncRNA在DC分化和功能中作用的研究,发现并鉴定了特异性高表达于DC的1ncRNA,命名为1nc-DC,其可通过抑制STAT3去磷酸化,从而促进DC分化和功能。该研究成果发表于Science杂志[2014,344(6181):310-313],并于2015年12月被评为“中国百篇最具影响国际学术论文”。wang p xue y han y lin l wu c xu s jiang z xu j liu q cao x 2016中国肿瘤生物治疗杂志2016,23,1:10
8桑叶多糖对早期断奶仔猪生长性能、腹泻、血液指标和肠道菌群的影响显示文摘研究旨在探讨日粮补充桑叶多糖(MLPs)对早期断奶仔猪生长性能、腹泻、血液生化指标和肠道菌群的影响。共选取(28±2)日龄、体重为(9.18±0.46)kg的'杜洛克×长白×约克夏'杂交断奶仔猪150头,随机分成5个处理组,每组6个重复,每个重复5头猪。饮食处理如下:对照组(CT):基础日粮(BD);低剂量桑叶多糖组(LT):0.3 g·kg-1MLPs+BD;中剂量桑叶多糖组(MT):0.6 g·kg-1MLPs+BD;高剂量桑叶多糖组(HT):0.9 g·kg-1MLPs+BD;抗生素处理组(AT):0.15 g·kg-1金霉素+BD。分别在第0、10、21天的早晨,每头猪空腹测量体重并记录采食量,这些数据用来计算平均日增重(ADG)、平均日采食量(ADFI)和料重比(F/G)。每天两次(上午和下午)对每头仔猪的腹泻状况进行检查并记录。在试验结束时,收集血液样本用于生化分析,并收集盲肠、结肠和直肠内容物进行识别和量化相关的肠道菌群。研究结果表明,MLPs处理组间的日增重、平均日采食量和料重比无显著差异(P>0.05),但低剂量组(LT)、中剂量组(MT)、高剂量组(HT)的平均日采食量高于对照组(CT)和抗生素组(AT)。并且,LT、MT和HT组的料重比低于CT和AT组。与CT和AT组相比,LT、MT和HT组仔猪的腹泻发病率也显著降低(P<0.05)。生化分析表明,MLPs各处理组仔猪的血糖(GLU)水平均显著低于CT或AT组(P<0.05)。MT和HT组血液尿素氮(BUN)水平与CT和AT组存在显著差异(P<0.05),HT组T3水平显著高于CT和AT组(P<0.05)。虽然MLPs各处理组的T4水平与AT组并没有显著差异(P>0.05),但MT组的胰岛素样生长因子Ⅰ(IGF-Ⅰ)和生长激素(GH)水平较CT或AT组均显著升高(P<0.05)。LT、MT和HT 3组在抑制肠道大肠杆菌生长和促进肠道乳酸杆菌和双歧杆菌生长的整体效果上均优于CT和AT组。值得注意的是,与CT和AT组相比,HT组(0.9 g·kg-1MLPs)对抑制肠道大肠杆菌以及促进肠道有益菌群具有更显著效果(P<0.05)。结果表明,日粮添加桑叶多糖可以改善早期断奶仔猪肠道菌群的生态环境,降低腹泻率,提高整体生长性能。Zhao X J Lin L Luo Q L Ye M Q Luo G Q Kuang Z S 2015饲料博览2015,0,7:7

12Research on Abrasives in the Chemical Mechanical Polishing Process for Silicon Nitride Balls显示文摘Silicon nitride (Si 3N 4) has been the main material for balls in ceramic ball bearings, for its lower density, high strength, high hardness, fine thermal stability and anticorrosive, and is widely used in various fields, such as high speed and high temperature areojet engines, precision machine tools and chemical engineer machines. Silicon nitride ceramics is a kind of brittle and hard material that is difficult to machining. In the traditional finishing process of silicon nitride balls, balls are lapped by expensive diamond abrasive. The machining is inefficiency and the cost is high, but also lots of pits, scratch subsurface micro crazes and dislocations will be caused on the surface of the balls, the performance of the ball bearings would be declined seriously. In these year, a kind of new technology known as chemical mechanical polishing is introduced in the ultraprecision machining process of ceramic balls. In this technology, abrasives such as ZrO 2, CeO 2 whose hardness is close to or lower than the work material (Si 3N 4) are used to polishing the balls. In special slurry, these abrasives can chemo-mechanically react with the work material and environment (air or water) to generate softer material (SiO 2). And the resultants will be removed easily at 0.1 nm level. So the surface defects can be minimized, very smooth surface (Ra=4 nm) and fine sphericity (0.15~0.25 μm ) can be obtained, and the machining efficiency is also improved. The action mechanism of the abrasives in the chemical mechanical polishing process in finishing of silicon nitride ball will be introduced in this paper.YUAN Ju-long, Lü Bing-hai, LIN Xü, JI Shi-ming, ZHANG Li-bin (Mechanical and Electronic Engineering College, Zhejiang University of Technology, Hangzhou 310014, China) 2002厦门大学学报(自然科学版)2002,41,S1:5
