| 1 | Measurements of dihadron correlations relative to the event plane in Au+Au collisions at√^(S)NN=200 GeV显示文摘Dihadron azimuthal correlations containing a high transverse momentum(pr)trigger particle are sensit-ive to the properties of the nuclear medium created at RHIC through the strong interactions occurring between the traversing parton and the medium,ie.jet-quenching.Previous measurements revealed a strong modification to di-hadron azimuthal correlations in Au+Au collisions with respect to ptp and d+Au collisions.The modification in-creases with the collision centrality,suggesting a path-length or energy density dependence to the je-quenching ef-fect.This paper reports STAR measurements of dihadron azimuthal correlations in mid-central(20%-60%)Au+Au collisions at√^(S)NN=200 GeV as a function of the trigger particle's azimuthal angle relative to the event plane,Ф_(s)=|Ф_(t)-ψ_(Ep)|.The azimuthal correlation is studied as a function of both the trigger and associated particle pr.The subtractions of the combinatorial background and anisotropic flow,assuming Zero Yield At Minimum(ZYAM),are described.The correlation results are first discussed with subtraction of the even harmonic(elliptic and quadrangu-lar)flow backgrounds.The away-side correlation is strongly modifed,and the modification varies withФ_(s),with a double-peak structure for out-of-plane trigger particles.The near-side ridge(long range pseudo-rapidity△_(η)correla-tion)appears to drop with increasingФ_(s)while the jet-like component remains approximately constant.The correla-tion functions are further studied with the subtraction of odd harmonic triangular flow background arising from fluc-tuations.It is found that the triangular flow,while responsible for the majority of the amplitudes,is not sufficient to explain theφs-dependence of the ridge or the away-side double-peak structure.The dropping ridge withФ_(s)could be attributed to aФ_(s)-dependent lliptie anisotropy;however,the physics mechanism of the ridge remains an open ques-tion.Even with aФ_(s)-dependent elliptic flow,the away-side correlation structure is robust.These results,with extens-ive systematic studies of the dihadron correlations as a function ofФ_(s),trigger and associated particle pT,and the pseudo-rapidity range△_(η),should provide stringent inputs to help understand the underlying physics mechanisms of jet-medium interactions in high energy nuclear collisions. | H.Agakishiev M.M.Aggarwal Z.Ahammed A.V.Alakhverdyants I.Alekseev J.Alford B.D.Anderson C.D.Anson

| 2 | Methods for a blind analysis of isobar data collected by the STAR collaboration显示文摘In 2018,the STAR collaboration collected data from^(96)_(44)Ru+^(96)_(44)Ru and^(96)_(40)Zr+^(96)_(40)Zr at√^(S)NN=200 Ge V to search for the presence of the chiral magnetic effect in collisions of nuclei.The isobar collision species alternated frequently between 9644 Ru+^(96)_(44)Ru and^(96)_(40)Zr+^(96)_(40)Zr.In order to conduct blind analyses of studies related to the chiral magnetic effect in these isobar data,STAR developed a three-step blind analysis procedure.Analysts are initially provided a'reference sample'of data,comprised of a mix of events from the two species,the order of which respects time-dependent changes in run conditions.After tuning analysis codes and performing time-dependent quality assurance on the reference sample,analysts are provided a species-blind sample suitable for calculating efficiencies and corrections for individual≈30-min data-taking runs.For this sample,species-specific information is disguised,but individual output files contain data from a single isobar species.Only run-by-run corrections and code alteration subsequent to these corrections are allowed at this stage.Following these modifications,the'frozen'code is passed over the fully un-blind data,completing the blind analysis.As a check of the feasibility of the blind analysis procedure,analysts completed a'mock data challenge,'analyzing data from Au+Au collisions at√^(S)NN=27 Ge V,collected in 2018.The Au+Au data were prepared in the same manner intended for the isobar blind data.The details of the blind analysis procedure and results from the mock data challenge are presented. | J.Adam L.Adamczyk J.R.Adams J.K.Adkins G.Agakishiev M.M.Aggarwal Z.Ahammed

| 4 | 幽门螺杆菌根除治疗对非酒精性脂肪肝病患者肝脂肪变化的影响:一项随机对照先导研究显示文摘背景:幽门螺杆菌(Hp)感染可导致胰岛素抵抗和非酒精性脂肪肝病(NAFLD)。本研究旨在评估Hp根除治疗(HPET)与标准治疗(SMT)对NAFLD患者的影响。方法:80例伴有Hp感染的NAFLD患者随机分入SMT组(36例,饮食和锻炼)和HPET组(44例,除饮食和锻炼标准治疗外,予以阿莫西林+克拉红霉素+泮托拉唑三联疗法对Hp进行根除治疗)。检测受控衰减参数(CAP)、体脂参数、肝酶、血脂及包括稳态模型胰岛素抵抗指数(HOMA-IR)在内的血糖参数,比较治疗前及治疗后24周两组患者上述指标的差异。结果:64例患者纳入改良意向性分析,其中SMT组28例,HPET组36例。治疗后24周,SMT组和HPET组患者CAP评分均显著下降(P=0.002和P<0.001),但CAP变化值两组差异无统计学意义(P=0.213)。24周时,HPET组有68%的患者成功根除Hp,与治疗无应答者及SMT组患者相比,Hp根除者HOMA-IR显著改善(P=0.007)。治疗后24周,两组患者肝酶水平均显著下降,但变化值两组差异无统计学意义;血脂水平在治疗前后无显著改变,且两组间差异亦无统计学意义。HPET组患者谷胱甘肽显著下降,但变化值两组差异无统计学意义。结论:与标准治疗相比,辅以Hp根除治疗并不能进一步减轻NAFLD患者的肝脂肪变性和进一步降低肝酶水平,但成功根除Hp可以使HOMA-IR获得显著改善(临床注册号:CTRI/2017/05/008608)。 | Vikas Maharshi Pooja Gupta Vijay L.Kumar Ashish Datt Upadhyay Prasenjit Das Rajni Yadav Baibaswata Nayak Ramesh Kumar Shalimar | 2020 | Gastroenterology Report2020，8，2： | 1 |
| 5 | Best practices in teaching endoscopy according to a Delphi survey of gastroenterology trainees显示文摘Introduction Endoscopy is a core component of gastroenterology training[1],yet there are no guidelines on how endoscopists should teach the procedure[2].Across most programs in the USA,endoscopy training follows an apprenticeship model,in which trainees develop skills through supervised,hands-on practice[3].Although some programs use assessment tools to determine proficiency in performing endoscopy procedures,most rely principally on procedural volume and subjective evaluations.As a result,endoscopic training is variable across and within institutions. | Michael Fuchs Justin L.Sewell Navin L.Kumar | 2021 | Gastroenterology Report2021，9，6： | 0 |

| 7 | 基于网络的上消化道内镜SAFE-T工具:实时评估胃肠专科医生内镜培训效果显示文摘背景:导师评估是胃肠专科医生内镜培训的一个关键部分。本研究旨在建立和验证一个简明的、基于网络的上消化道内镜培训效果实时评估工具。方法:我们建立了针对上消化道内镜的专科医生内镜培训技能评估(SAFE-T)工具,在一个5部分的问卷中获取总结性和格式化的反馈。该工具与既往已获验证的结肠镜SAFE-T相似,是基于网络开展应用的。我们应用该工具对2018-2019学年的15名胃肠专科医生(培训期1、2、3年各5名)。为确保评估的可靠性,由一名独立评审人对不同的上消化道内镜操作技术进行评估,完成SAFE-T和内镜能力评估(ACE)两份量表。结果:20名高年资医生在研究期间对15名专科医生进行了413次SAFE-T评估。不同培训学年的专科医生平均SAFE-T评分存在显著差异,第一学年医生的评分低于第二学年(3.31 vs 4.25,P<0.001),第二学年低于第三学年(4.25 vs 4.56,P<0.001)。随着内镜操作难度的增加,平均SAFE-T评分下降,简单操作的评分高于中等操作(3.98 vs 3.39,P<0.001),中等操作高于困难操作(3.39 vs 2.84,P=0.042)。导师与独立评审人同时观察评估一项内镜操作,其SAFE-T评分一致性良好(Kappa=0.815,P=0.001)。SAFE-T评分与ACE评分高度相关(r=0.76,P=0.011)。结论:我们建立并验证了SAFE-T这种简明的、基于网络的工具,用以实时评估胃肠专科医生上消化道内镜培训效果的有效性。 | Navin L.Kumar Guillaume Kugener Kelly E.Hathorn Molly L.Perencevich Kunal Jajoo John R.Saltzman | 2020 | Gastroenterology Report2020，8，6： | 0 |
| 8 | Antimalarial drug artesunate affords protection against carrageenan induced acute inflammation in rat显示文摘Artesunate, an antimalarial drug, has been shown to inhibit the release of inflammatory mediators in various disease conditions. The present study was carried out to evaluate the anti-edematogenic effect of arte- sunate in the rat paw edema model. Inflammation was induced in the hind paw of rat by sub-plantar injection of 0.1 mL of 0.5% carrageenan and the paw volume was measured up to a fixed mark just before the injection and then after 3 h. The difference in two volumes gave a measure of edema formation. At 3h the level of TNF-α, PGE_(2) and myeloperoxidase were estimated in the inflamed paw tissue. Treatment of rats with single dose of artesunate at 50 and 150 mg/kg produced a dose-dependent inhibition in paw inflammation where a significant reduction in edema volume and mediator release was observed. Our study shows that by inhibiting the release of inflam- matory mediators artesunate affords protection against acute inflammation induced in the rat paw and suggests that it has a potential to be used in the treatment of inflammatory disease conditions. | Vijay L.KUMAR B.GURUPRASAD Priyanka CHAUDHARY | 2014 | BIOCELL2014，38，1： | 0 |
