1全科医学科研的范畴、研究需求和适用方法——《欧洲全科医学/家庭医学和基本医疗保健科研纲要》中文摘译显示文摘本文对《欧洲全科医学/家庭医学和基本医疗保健科研纲要》的中文译稿进行了重点摘登。该文件由欧洲全科医学科研网络制订,包括7部分内容:序言、导言、方法、结果、独立章节,讨论和启示。作为在欧洲发展全科医学科研的核心指南,该文件对欧洲的全科医学学科和科研发展产生了深远的影响。欧洲的全科医学体系和以此为基础而构建的学科理论共识与我国全科医学当前的实际情况可能更为接近。因篇幅所限,本文刊登了其中最重要,对中国研究者也最实用的5部分内容,包括:(1)导言——全科医学的核心能力/特征以及全科医学科研的意义;(2)结果——全科医学的6个核心领域(基本保健管理、'以人为本'的照护、解决具体问题的技能、综合的方法、以社区为导向、整体的方法)的科研范畴,研究需求和适用方法;(3)独立章节——如何发展基本的科研能力和避免常见的科研失误;(4)讨论——未来的全科医学科研重点;(5)启示——科学协会、研究机构、患者参与、科研工作、期刊、科研政策在发展学科方面应注重的问题。因欧洲的全科医学体制和我国较为相似,且存在一定的科研发展代差,该文件在当前阶段也可为我国全科医学研究者所用,基于全科医学学科的视角,从概念、分类学、范围和科研方法等方面,为我国全科医学科研的发展提供参照。Eva Hummers-Pradier Martin Beyer Patrick Chevallier Sophia Eilat-Tsanani Christos Lionis Lieve Peremans Davorina Petek Imre Rurik Jean Karl Soler Henri E.J.H.Stoffers Pinar Topsever Mehmet Ungan Paul van Royen Hanny Prick 2022中国全科医学2022,25,9:4
2The E3 Ubiquitin Ligase gp78 Protects against ER Stress in Zebrafish Liver显示文摘Enhanced endoplasmic reticulum(ER)-associated protein degradation(ERAD) activity by the unfolded protein response(UPR) represents one of the mechanisms for restoring ER homeostasis.In vitro evidence indicates that the mammalian gp78 protein is an E3 ubiquitin ligase that facilitates ERAD by polyubiquitinating and targeting proteins for proteasomal degradation under both physiologic and stress conditions.However,the in vivo function of gp78 in maintaining ER protein homeostasis remains untested.Here we show that like its mammalian counterpart,the zebrafish gp78 is also an E3 ubiquitin ligase as revealed by in vitro ubiquitination assays.Expression analysis uncovered that gp78 is highly expressed in several organs,including liver and brain,of both larval and adult fish.Treatment of larvae or adult fish with tunicamycin induces ER stress and upregulates the expression of several key components of the gp78 ERAD complex in the liver.Moreover,liver-specific overexpression of the dominant-negative form of gp78(gp78-R2M) renders liver more sensitive to tunicamycin-induced ER stress and enhances the expression of sterol response element binding protein(Srebp)-target genes,which was largely suppressed in fish overexpressing wild-type gp78.Together,these data indicate that gp78 plays a critical role in protecting against ER stress in liver.Zhiliang Chen Petek Ballar Yu Fu Jia Luo Shaojun Du Shengyun Fang 2014Journal of Genetics and Genomics2014,41,7:3
3海兰W-80父母代种鸡产蛋曲线数学模型分析研究显示文摘为探究海兰W-80父母代种鸡在我国饲养环境下的产蛋规律,本实验分别测定了3个种鸡场各10827、10147、21204只海兰W-80父母代种鸡全期产蛋性能,分别采用伍德模型(Woodmodel)、分室模型(McMillan model)和杨宁模型拟合其产蛋率曲线,使用Gompertz、Logistic和Von Bertalanffy模型拟合其累计产蛋数曲线,根据R^(2)、赤池信息准则(AIC)和贝叶斯信息准则(BIC)选择最优模型,并与饲养标准进行产蛋性能比较。结果显示,曲线拟合模型F检验均差异显著,可用于海兰W-80父母代种鸡产蛋率和累计产蛋数拟合;产蛋率拟合杨宁模型R^(2)最高(R^(2)=0.987~0.994),分室模型次之(R2=0.927~0.977),伍德模型拟合度最低(R2=0.509~0.652),且AIC与BIC指数依次为杨宁模型<分室模型<伍德模型。Gompertz、Logistic、Von Bertalanffy模型拟合3个种鸡场累计产蛋数曲线R^(2)分别为0.996~0.997、0.989~0.990、0.998~0.999,且VonBertalanffy模型AIC与BIC指数最低。本实验中海兰W-80父母代种鸡开产较饲养标准早4~11 d,70周龄累计产蛋数高于标准上限5~12个,但92%产蛋率高峰持续时间较短。综上,杨宁模型和Von Bertalanffy模型分别适用于海兰W-80父母代种鸡产蛋率和累计产蛋数的拟合,可评估和预测其产蛋规律。此外,应避免种鸡开产过早,以防产蛋高峰持续时间缩短,影响全期产蛋性能。曾丹 闫文亮 Petek Settar Turkmut 李秀业 王斌 韩晓飞 石玉祥 高亚辉 2021中国畜牧杂志2021,57,10:2
4十五肽BPC157减弱慢性苯丙胺诱导的行为障碍(英文)显示文摘AIM: To investigate the effect of pentadecapeptide BPC 157 on chronic exposure to amphetamine in rats, particularly the changes commonly referred in chronic amphetamine studies as tolerance ( lesser grade of stereotyped behavior, without increased excitability) and reverse tolerance (ie, prominent stereotyped behavior and heightened startle response upon late amphetamine challenges). METHODS: After initial application (initial single dose-regimen), amphetamine (10 mg/kg, ip) was given once daily till d 5 ( continuous administration-regimen), and thereafter on d 8, 16, and 46 (intermittent administration regimen). For stereotyped behavior and heightened startle response the observation period was 120 min after amphetamine application, and each animal was observed for 10 s in 5 min intervals. Pentadecapeptide BPC 157 (10 μg/kg or 10 ng/kg, ip) or saline (5.0 mL/kg, ip) were given only at the beginning of the experiment, simultaneously with the initial dose of amphetamine. RESULTS: In relation toPredrag SIKIRIC, Nikola JELOVAC, Andjelka JELOVAC-GJELDUM, Goran DODIG, Mario STARESINIC, Tornislav ANIC, Ivan ZORICIC, Davor RAK, Darko PEROVIC, Gorana ARALICA, Gojko BULJAT, Ingrid PRKACEV, Martina LOVRIC-BENCIC, Jadranka SEPAROVIC, Sven SEIWERTH, Rudolf RUCMAN, Marijan PETEK, Branko TURKOVIC, Tihomil ZIGER, AJenka BOBAN-BLAGAIC, Vlado BEDEKOVIC, Ante TONKIC, Slaven BABIC ( Department of Pharmacology, Medical Faculty University of Zagreb, Croatia) 2002Acta Pharmacologica Sinica2002,23,5:2
