3Sedation and safety of propofol for therapeutic endoscopic retrograde cholangiopancreatography显示文摘Endoscopic retrograde cholangiopancrea tography(ERCP) is the most complex gastrointestinal procedure,which needs patients’ cooperation. The aim of this study was to observe the quality and safey of sedation with propofol in patients undergoing therapeutic ERCP. METHODS:Seventy patients who had undergone therapeutic ERCP were randomly divided into two groups.One group, given intravenously propofol, and the other sedated with routine method, served as the control. Blood pressure, heart rate,oxygen saturation were monitored and cardiorespiratory event was observed. Patient cooperation,performance, recovery time and amnesia served as variables postoperation. RESULTS:Blood pressure elevated in four patients in the propofol group, less than in the control group(P<0.01). Seven patients showed decreased blood pressure after administration of propofol,but none in the control group (P<0.01). Twelve patients in the control group showed mild or significant resistance, but none in the propofol group (P<0.01). The time for performance in the propofol group(P<0.05) was shorter than in the control group. Patient recovery was quicker in the propofol group than in the control group (P<0.01). The degree of amnesia better in the propofol group than in the control group ( P<0.01). The degree of amnesia was also better in the propofol group than in the control group (P<0.01). CONCLUSIONS:Propofol proves to be an excellent sedative for therapeutic ERCP. Being effective and safe, it shows a shorter ERCP duration but quick recovery and better amnesia. It is better than other routine sedatives.Digestive Department (Chen WX, Lin HJ, Gu Q, Zhong XQ, Yu CH, Li YM and Gu ZY) and Department of Intensive Care Unit (Zhang WF), First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou 310003 , China 2005Hepatobiliary & Pancreatic Diseases International2005,4,3:10
4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
5The biological function of type I receptors of bone morphogenetic protein in bone显示文摘Bone morphogenetic proteins(BMPs) have multiple roles in skeletal development, homeostasis and regeneration. BMPs signal via type I and type II serine/threonine kinase receptors(BMPRI and BMPRII). In recent decades, genetic studies in humans and mice have demonstrated that perturbations in BMP signaling via BMPRI resulted in various diseases in bone, cartilage, and muscles. In this review, we focus on all three types of BMPRI, which consist of activin-like kinase 2(ALK2, also called type IA activin receptor), activinlike kinase 3(ALK3, also called BMPRIA), and activin-like kinase 6(ALK6, also called BMPRIB). The research areas covered include the current progress regarding the roles of these receptors during myogenesis,chondrogenesis, and osteogenesis. Understanding the physiological and pathological functions of these receptors at the cellular and molecular levels will advance drug development and tissue regeneration for treating musculoskeletal diseases and bone defects in the future.Shuxian Lin Kathy KH Svoboda Jian Q Feng Xinquan Jiang 2016Bone Research2016,4,2:10
6A Novel Square-wave Pulse Rotation Modulation Strategy for Modular Multilevel Converters显示文摘悬浮直流电容电压的均衡问题是模块组合多电平变换器(modular multilevel converter,MMC)的关键问题之一。提出一种可实现MMC直流电容电压平衡的方波脉冲循环调制(square-wave pulse rotation modulation,SWPRM)策略,在保证合成的阶梯波输出波形不变的前提下,根据MMC的拓扑结构和工作原理,对传统方波脉冲列进行脉冲优化,并按照一定的次序和切换周期进行循环和判断反相调整,获得的循环方波脉冲列作为最终驱动脉冲用于实现对MMC的控制。实验结果表明,采用提出的方波脉冲循环调制策略无需任何电容电压控制措施,在较低开关频率下,实现了MMC各功率单元间有功能量的平均分配和直流电容电压的均衡。YANG Xiaofeng LIN Zhiqin ZHENG Trillion Q YOU Xiaojie 2013中国电机工程学报2013,33,9:9
7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

9全颗粒饲料对奶牛生产性能的影响显示文摘饲料中的中性洗涤纤维(NDF)含量和饲料颗粒直径是影响瘤胃功能的重要因素。试验评估了以颗粒饲料为主的奶牛瘤胃健康情况、NDF消化率和生产性能。选取8头荷斯坦母牛(336±30 d,体重346±35 kg),随机分配到交叉重复试验组中,奶牛安置于牛栏,自由采食。试验期为3周,前两周是适应期,最后一周为数据收集期。各组饲粮原料相同,但物理形式不同,分为全混合日粮(TMR)和颗粒料(直径=8 mm)。两组间物理有效NDF(pe NDF)不同,TMR组为39.8%,颗粒料组为11.8%。在试验过程中,干物质采食量(DMI)、饮水量、瘤胃反刍时间、瘤胃温度和pH情况均记录。3周后收集粪样,确定潜在的可消化NDF总消化率(pdNDF)。每阶段结束后计算平均日增重和饲料转化率。颗粒料组的DMI、DMI/体重和饮水量更高。而两组间平均日增重和饲料转化率无显著差异。颗粒料组的瘤胃反刍时间为241 min·d-1低于TMR组的507 min·d-1。饲料的不同物理外形对瘤胃温度、瘤胃pH无显著影响。TMR组的pdNDF总消化率为90.25%高于颗粒料组的86.82%。试验结果表明,动物易接受完整的颗粒饲料,DMI较高,且反刍时间减少,但瘤胃pH无显著变化。TMR组的pdNDF消化率显著增加。尽管两组奶牛在DMI和纤维消化方面表现不同,但总体表现相似,两组饲料的保存时间与其物理形式有关。在短期内,提供能满足NDF需求的完全颗粒饲料可改善瘤胃健康状况和动物生产性能,而较长时间的数据则需要进一步试验。Wang J Yang M Cao M Lin Y Che L Q Duraipandiyan V Al-Dhabi N A Fang Z F Xu S Y Feng B Liu G Wu D Bonfante E Palmonari A Mammi L Canestrari G Fustini M Formigoni A 2016饲料博览2016,0,12:2
