2紧急避孕药系统评估显示文摘目的:评估两种(0.75mg双剂、1.5mg单剂)左炔诺孕酮(LNG)及两种低剂量(10mg、25mg)米非司酮(MFP)紧急避孕方案的有效性和副作用。方法:通过电子及手工检索方式检索相关文献,筛选出其中的随机对照临床试验,提取信息并进行Meta分析。结果:共检索到63篇相关文献,其中28篇纳入本评估。结果显示,两种剂量LNG方案有效性及副反应的发生率均相似。在服用紧急避孕药后无性生活的对象中,25mgMFP与10mgMFP(方法失败率)相似,然而25mgMFP总失败率(在所有对象中计算出的失败率)略低于10mgMFP,但差别没有统计学意义。25mgMFP方案恶心发生率比10mgMFP方案略高。10mgMFP方案与单剂1.5mgLNG方案总失败率相似,而前者方法失败率略低。25mgMFP方案方法失败率与总失败率均略低于单剂及双剂LNG方案,但差别无统计学意义。MFP紧急避孕方案月经延迟的发生率比LNG方案高,而后者点滴出血的发生率比前者高。无保护性生活后越早接受紧急避孕,失败率越低。结论:两种LNG方案和两种MFP方案有效性和副反应发生基本相似,由于LNG为传统避孕药物,其安全性已被证实,并为非处方药,故优先推荐使用LNG方案,单剂1.5mgLNG方案更为方便。孙月莲 车焱 丁永刚 周维谨 韩耀玲 方可娟 Olav Meirik Peter Fajans 2005中国计划生育学杂志2005,13,4:11
3预变形结合人工时效对Al-Mg-Si合金力学性能的影响(英文)显示文摘研究预变形结合人工时效处理对AA6060铝合金强度和韧性的影响。对经过均匀化热处理和挤压加工的AA6060铝合金进行固溶处理,然后对材料实施0-10%的预变形并再进行时效处理或者在人工时效过程中进行同步变形。通过对不同时效处理后的合金的显微硬度和拉伸性能分析,发现预变形对材料的时效行为和力学性能有显著影响,它可以使合金的时效速度明显加快。比较预变形和同步变形对人工时效的影响发现,同步变形结合人工时效可以使该合金在更短的时间内得到更好的力学性能。对两种变形对时效行为的影响机理进行了探讨。Michal KOLAR Ketill Olav PEDERSEN Sverre GULBRANDSEN-DAHL Knut MARTHINSEN 2012Transactions of Nonferrous Metals Society of China2012,22,8:10

53D non-isothermal phase-field simulation of microstructure evolution during selective laser sintering显示文摘During selective laser sintering(SLS),the microstructure evolution and local temperature variation interact mutually.Application of conventional isothermal sintering model is thereby insufficient to describe SLS.In this work,we construct our model from entropy level,and derive the non-isothermal kinetics for order parameters along with the heat transfer equation coupled with microstructure evolution.Influences from partial melting and laser-powder interaction are also addressed.We then perform 3D finite element non-isothermal phase-field simulations of the SLS single scan.To confront the high computation cost,we propose a novel algorithm analogy to minimum coloring problem and manage to simulate a system of 200 grains with grain tracking algorithm using as low as 8 non-conserved order parameters.Specifically,applying the model to SLS of the stainless steel 316L powder,we identify the influences of laser power and scan speed on microstructural features,including the porosity,surface morphology,temperature profile,grain geometry,and densification.We further validate the first-order kinetics of the transient porosity during densification,and demonstrate the applicability of the developed model in predicting the linkage of densification factor to the specific energy input during SLS.Yangyiwei Yang Olav Ragnvaldsen Yang Bai Min Yi Bai-Xiang Xu 2019npj Computational Materials2019,,1:8
6钠-葡萄糖共转运蛋白-2抑制剂或胰高血糖素样肽-1受体激动剂治疗成人2型糖尿病:临床实践指南显示文摘临床问题对于存在不同心血管风险及肾脏结局的2型糖尿病患者,在原有生活方式干预和/或其他降糖药物的基础上加用钠-葡萄糖共转运蛋白2(SGLT-2)抑制剂和胰高血糖素样肽1(GLP-1)受体激动剂的获益及风险是什么?现行做法几十年来,2型糖尿病的治疗决策都以控制血糖为主导。SGLT-2抑制剂和GLP-1受体激动剂在传统观念中常被用于二甲双胍治疗后血糖仍控制不佳的患者。目前这一现状已经发生了改变,这得益于多项临床研究结果。研究显示SGLT-2抑制剂和GLP-1受体激动剂拥有独立于药物降糖作用之外的对于动脉粥样硬化性心血管病(CVD)和慢性肾脏病(CKD)的获益。建议本指南阐述了针对不同风险分层的成人2型糖尿病患者使用SGLT-2抑制剂或GLP-1受体激动剂的建议。•伴有3种或更少的心血管风险因素且不存在CVD或CKD:不建议启动SGLT-2抑制剂或GLP-1受体激动剂治疗。(推荐等级:弱)•伴有3种以上心血管风险因素且不存在CVD或CKD:建议启动SGLT-2抑制剂治疗,不建议启动GLP-1受体激动剂治疗。(推荐等级:弱)•已经存在CVD或CKD:建议启动SGLT-2抑制剂治疗和GLP-1受体激动剂治疗。(推荐等级:弱)•已经存在CVD和CKD:建议启动SGLT-2抑制剂治疗(推荐等级:强)和GLP-1受体激动剂治疗。(推荐等级:弱)•对于那些想要进一步降低CVD和CKD结局风险的患者:推荐优先启用SGLT-2抑制剂治疗而非GLP-1受体激动剂治疗。(推荐等级:弱)这项指南是如何制订的一个由患者、临床医生和方法学家共同组成的国际小组提出了这些推荐意见。这些推荐意见基于可信度较高的指南的标准,并使用GRADE分级方法进行评估。该小组采用了息者个体化的观点。证据一项关于获益与风险的系统综述和网络meta分析(764项随机对照研究,包括421346例参与者)发现SGLT-2抑制剂和GLP-1受体激动剂可以降低总体死亡率、心肌梗死发生率、终末期肾病或肾衰竭的发生率(中等至高等质量的证据)。在不同的亚组中这些药物对卒中、因心力衰竭所致住院和其他主要不良事件有不同的影响。药物绝对获益的程度因患者个体风险的不同有很大的差异。(例如,对于接受了超过5年药物治疗的1000例患者,在最低风险人群中死亡人数减少了5人,在最高风险人群中死亡人数减少了48人)。一项关于预后的综述确认了14种风险预测模型,其中一种(RECODe)在证据总结中报告了大部分基线风险评估数据,小组利用该模型以支持风险分层的建议。考虑到患者的价值观及个体差异,指南推荐的支撑证据包括一项对已发表论文的系统综述、一项患者焦点小组研究、一项临床问题总结,以及一项指南调查。指南解读我们依据不同的CVD和CKD风险水平,综合考虑获益、风险和其他因素的平衡,以及每一个风险组别的实际问题,来对推荐意见进行分层。本指南强烈建议CVD和CKD患者使用SGLT-2抑制剂治疗,这说明专家组认为其具有显著的获益。而对于其他成人2型糖尿病患者,推荐等级较弱,这说明专家组想要在获益、风险及治疗花费上取得一个更好的平衡。临床医生通过该指南可以使用可靠的风险计算模型,如RECODe,来明确其患者的个体心血管和肾脏疾病风险。医患交互式总结临床证据和制订决策有助于患者知晓治疗选择,包括进行共同决策。2型糖尿病人群(全球患病率不断增长1-2)正面临着不断增加的心血管疾病、肾脏病和其他并发症的风险3。数十年来,2型糖尿病的管理始终以控制血糖及糖化血红蛋白(HbA1c)为治疗目标4-5,但是,最近的高质量随机对照研究已经对这种以血糖为中心的治疗模式发起了挑战。研究结果显示,强化血糖控制未必会降低大血管不良事件,它还可能带来不利影响监管机构现在要求新型糖尿病药物必须证明其具有心血管和肾脏获益才能获得批准。对两类新药--钠-葡萄糖共转运蛋白2(SGLT-2)抑制剂和胰高血糖素样肽1(GLP-1)受体激动剂(见框图1)的临床试验结果显示,在现有治疗方案(常规治疗)之上加用这些药物,对死亡、心肌梗死、卒中、心力衰竭和肾脏的结局(如进展为终末期肾病)都有获益8-12。Sheyu Li Per Olav Vandvik Lyubov Lytvyn Gordon H Guyatt Suetonia C Palmer Rene Rodriguez-Gutierrez Farid Foroutan Thomas Agoritsas Reed A C Siemieniuk Michael Walsh Lawrie Frere David J Tunnicliffe Evi V Nagler Veena Manja Bjφrn Olav Asvold Vivekanand Jha Mieke Vermandere Karim Gariani Qian Zhao Yan Ren Emma Jane Cartwright Patrick Gee Alan Wickes Linda Fems Robin Wright Ling Li Qiukui Hao Reem A Mustafa 郭鹤鸣(译) 2021英国医学杂志中文版2021,24,9:7
7Non-invasive biomarkers for monitoring the fibrogenic process in liver:A short survey显示文摘The clinical course ofchronic liver diseases is significantly dependent on the progression rate and the extent offibrosis, i.e. the non-structured replacement of necrotic parenchyma by extracellular matrix. Fibrogenesis, i.e. the development offibrosis can be regarded as an unlimited wound healing process, which is based on matrix (connective tissue) synthesis in activated hepatic stellate cells, fibroblasts (fibrocytes), hepatocytes and biliary epithelial cells, which are converted to matrix-producing (myo-)fibroblasts by a process defined as epithelial-mesenchymal transition. Blood (noninvasive) biomarkers offibrogenesis and fibrosis can be divided into class and class analytes. Class biomarkers are those single tests, which are based on the pathophysiology offibrosis, whereas class biomarkers aremostly multiparametric algorithms, which have been statistically evaluated with regard to the detection and activity ofongoing fibrosis. Currently available markers fulfil the criteria ofideal clinical-chemical tests only partially, but increased understanding ofthe complex pathogenesis offibrosis offers additional ways for pathophysiologically well based serum (plasma) biomarkers. They include TGF-β-driven marker proteins, bone marrow-derived cells (fibrocytes), and cytokines, which govern proand anti-fibrotic activities. Proteomic and glycomic approaches ofserum are under investigation to set up specific protein or carbohydrate profiles in patients with liver fibrosis. These and other novel parameters will supplement or eventually replaceliver biopsy/histology, high resolution imaging analysis, and elastography for the detection and monitoring of patients at risk ofdeveloping liver fibrosis.Axel M Gressner Chun-Fang Gao Olav A Gressner 2009World Journal of Gastroenterology2009,15,20:5
8我国长效口服避孕药的系统评估显示文摘目的:评估复方炔诺孕酮和复方左炔诺孕酮两种长效口服避孕药的有效性、安全性和可接受性。方法:见“我国常用口服避孕药和宫内节育器系统评估方法概述”(中国计划生育学杂志, 2005年1期17页)。结果:一项随机对照临床试验的结果显示,复方左炔诺孕酮的失败率(校正Pearl指数:1 1 /100妇女年)显著低于复方炔诺孕酮(2 3 /100妇女年) (P<0 05),复方左炔诺孕酮和复方炔诺孕酮1年续用率分别为82 05 /100妇女和73 62 /100妇女,副反应和月经紊乱是两种长效药停用的主要原因;其他研究提示,复方炔诺孕酮的1年失败率2 0 /100妇女,恶心、头昏和白带增多等副反应发生率超过50%,且白带增多不随服药周期的增加而减少,其它副反应,如恶心、头昏、头痛和经量改变等随使用周期的延长而减少;部分研究的临床和实验室检测结果显示,复方左炔诺孕酮和复方炔诺孕酮对血压、血脂和肝功能等指标有影响。结论:已有的数据表明长效口服避孕药的有效性低于其它长效激素类避孕方法和短效口服避孕药。长效口服避孕药中雌激素含量是目前使用的短效口服药中1个月炔雌醇合计量的4 8倍,基于现有资料和已被证实的长期使用高剂量雌激素的危险性,建议临床不提倡使用长效口服避孕药。丁永刚 方可娟 周维谨 车焱 孙月莲 韩耀玲 Olav Meirik Peter Fajans 2005中国计划生育学杂志2005,13,6:5

13Connective tissue growth factor reacts as an IL-6/STAT3-regulated hepatic negative acute phase protein显示文摘AIM:To investigate the mechanisms involved in a possible modulator role of interleukin(IL) -6 signalling on CYR61-CTGF-NOV(CCN) 2/connective tissue growth factor(CTGF) expression in hepatocytes(PC) and to look for a relation between serum concentrations of these two parameters in patients with acute inflammation. METHODS:Expression of CCN2/CTGF,p-STAT3,p-Smad 3/1 and p-Smad2 was examined in primary freshly isolated rat or cryo-preserved human PC exposed to various stimuli by Western blotting,electrophoretic mobility shift assay(EMSA) ,reporter-gene-assays and reversetranscriptase polymerase chain reaction. RESULTS:IL-6 strongly down-regulated CCN2/CTGF protein and mRNA expression in PC,enhanceable by extracellular presence of the soluble IL-6 receptor gp80,and supported by an inverse relation between IL-6 and CCN2/CTGF concentrations in patients'sera.The inhi-bition of TGFβ1 driven CCN2/CTGF expression by IL-6 did not involve a modulation of Smad2(and Smad1/3) signalling.However,the STAT3 SH2 domain binding peptide,a selective inhibitor of STAT3 DNA binding activity,counteracted the inhibitory effect of IL-6 on CCN2/CTGF expression much more pronounced than pyrrolidine-dithiocarbamate,an inhibitor primarily of STAT3 phosphorylation.An EMSA confirmed STAT3 binding to the proposed proximal STAT binding site in the CCN2/CTGF promoter. CONCLUSION:CCN2/CTGF is identified as a hepatocellular negative acute phase protein which is downregulated by IL-6 via the STAT3 pathway through interaction on the DNA binding level.Olav A Gressner Ieva Peredniene Axel M Gressner 2011World Journal of Gastroenterology2011,17,2:3
14Experimental Investigation on the Vapor Chambers with Sintered Copper Powder Wick显示文摘High power electronics units generate high-density heat flux,which poses a significant threat to the reliability of these devices.The vapor chamber(VC)has a very high heat transfer rate and has a wide range of applications in the heat dissipation of electronic products.VCs with sintered copper powder wicks sized as irregular shape copper powder 50μm(I-50μm),I-75μm,I-110μm,I-150μm were studied in this paper.The effect of liquid filling ratio was discussed.The results indicated that the thermal resistance of all VCs decreased with the increase of heating power.The capillary performance of wick was the dominant factor for the heat transfer performance of VCs with different kinds of wick.A capillary performance factor was proposed to evaluate the capillary performance of VCs.The capillary performance factor of VC with the wick of I-75μm was much higher than that of the other types of VC in this study.The heat source surface temperature of VCs could be affected by filling ratio and wick structure.But,it should be insensitive to the filling ratio when a better capillary performance factor was obtained.With the same heating area and similar structure,the maximum heat flux density of the VC would decrease as the height of vapor cavity decreased.HUANG Dou JIA Li WU Hong AAKER Olav 2021Journal of Thermal Science2021,30,6:3

16The oral commensal Streptococcus mitis activates the aryl hydrocarbon receptor in human oral epithelial cells显示文摘Streptococcus mitis(S. mitis) is a pioneer commensal bacterial species colonizing many of the surfaces of the oral cavity in healthy individuals. Yet, not much information is available regarding its interaction with the host. We used examination of its transcriptional regulation in oral keratinocytes to elucidate some of its potential roles in the oral cavity. Transcription factor analysis of oral keratinocytes predicted S. mitis-mediated activation of aryl hydrocarbon receptor(Ah R). Activation and functionality of Ah R was confirmed through nuclear translocation determined by immunofluorescence microscopy and real-time polymerase chain reaction with reverse transcription analysis of CYP1A1, the hallmark gene for Ah R activation. Addition of Streptococcus mutans or Streptococcus gordonii did not induce CYP1A1 transcription in the keratinocyte cultures. Introduction of an Ah R-specific inhibitor revealed that S. mitis-mediated transcription of CXCL2 and CXCL8 was regulated by Ah R. Elevated levels of prostaglandin E2(enzyme-linked immunosorbent assay) in supernatants from S. mitis-treated oral epithelial cells were also attenuated by inhibition of Ah R activity. The observed Ah R-regulated activities point to a contribution of S. mitis in the regulation of inflammatory responses and thereby to wound healing in the oral cavity. The concept that the oral commensal microbiota can induce Ah R activation is important, also in view of the role that Ah R has in modulation of T-cell differentiation and as an anti-inflammatory factor in macrophages.stian a engen gro h rørvik olav schreurs inger js blix karl schenck 2017International Journal of Oral Science2017,9,3:2
17无支架含铜宫内节育器(吉妮)与TCu380A宫内节育器:多中心随机比较性研究8年结果(摘要)显示文摘1前言 终止使用宫内节育器(IUD)的常见原因是出血、疼痛或出血和疼痛并存,以及脱落,这些情况可能与传统IUD的支架及大小密切相关。因此1980年天津和杰医疗器械有限公司开始研发无支架的含铜IUD。1989年,世界卫生组织(WHO)人类生殖研究与发展项目(HRP)组组织了吉妮IUD与TCu380AIUD的多中心随机临床比较性研究,评估两种IUD的妊娠率、脱落率和与IUD使用有关的终止率。Olav Meirik Patrick J.
