1用于储层预测和监测的地震属性技术显示文摘70年代与80年代期间,在石油勘探中用得最多的地震属性是基于振幅的瞬时属性。然而,到了90年代,地震属性技术在几个方面已经取得了巨大的进展。现在,地震属性技术的范围包括计算单道瞬时同相轴属性到提取更复杂的多道分时窗的地震同相轴属性以及到生成地震属性体。地震属性技术的应用电从简单检测振幅异常发展到监测流体前缘随时间的变化。地震属性技术能从地震数据中提取其他方法无法提取的信息,它能增加地球物理在石油工业目前的黄金焦点领域(即含油气储层预测、储层描述和储层监测)中的应用和价值。什么是地震属性地震属性是从地震数据中产生的几何的、运动学的、动力学或统计特征的具体测量。Quincy Chen Steve Sidney 张翠兰 1998国外油气勘探1998,10,2:32

4量子限域纳米半导体上低碳烷烃的光助催化氧化显示文摘利用So l-G el及摸板技术定向合成了具有量子限域特征的ZnFe2O4纳米半导体催化剂(Q-ZnFe2O4)。分别采用XRD,DRS,FS,In situ EPR及光催化等手段对合成的纳米半导体的结构,表面化学物理特性,表面界面电荷转移特性及选择催化特性进行了深入研究。研究结果表明:采用定向合成技术可以在室温下合成具有尖晶石结构的Q-ZnFe2O4纳米晶半导体。DRS及FS结果证明样品呈现显著的量子限域效应及表面界面效应。原位辐射顺磁共振光谱结果表明:光生的电子和空穴可以分别在体相及表相Fe3+位置被同时俘获。临氧条件下,量子限域Q-ZnFe2O4纳米半导体受光激发后,光生电子可由表相Fe3+转移给四面体位置的Zn2+,即表相Fe3+可以作为光生载流子的生成中心;吸附的分子氧可以俘获迁移的电子形成高活性的羟基自由基。温和条件下,Q-ZnFe2O4纳米晶半导体可以高效活化分子氧实现低碳烷烃的光催化选择氧化,其中醇类羟基化合物的选择性可接近60%。李新勇 王玉新 鞠晓东 陈永英 Quincy Teng 2006渤海大学学报(自然科学版)2006,27,1:5
5Assessing adequacy of emergency provider documentation among interhospital transferred patients with acute aortic dissection显示文摘BACKGROUND: Acute aortic dissection(AoD) is a hypertensive emergency often requiring the transfer of patients to higher care hospitals; thus, clinical care documentation and compliance with the Emergency Medical Treatment and Active Labor Act(EMTALA) is crucial. The study assessed emergency providers(EP) documentation of clinical care and EMTALA compliance among interhospital transferred AoD patients.METHODS: This retrospective study examined adult patients transferred directly from a referring emergency department(ED) to a quaternary academic center between January 1, 2011 and September 30, 2015. The primary outcome was the percentage of records with adequate documentation of clinical care(ADoCC). The secondary outcome was the percentage of records with adequate documentation of EMTALA compliance(ADoEMTALA). RESULTS: There were 563 electronically identified patients with 287 included in the final analysis. One hundred and five(36.6%) patients had ADoCC while 166(57.8%) patients had ADoEMTALA. Patients with inadequate documentation of EMTALA(IDoEMTALA) were associated with a higher likelihood of not meeting the American Heart Association(AHA) ED Departure SBP guideline(OR 1.8, 95% CI 1.03–3.2, P=0.04). Male gender, handwritten type of documentation, and transport by air were associated with an increased risk of inadequate documentation of clinical care(IDoCC), while receiving continuous infusion was associated with higher risk of IDoEMTALA.CONCLUSION: Documentation of clinical care and EMTALA compliance by Emergency Providers is poor. Inadequate EMTALA documentation was associated with a higher likelihood of patients not meeting the AHA ED Departure SBP guideline. Therefore, Emergency Providers should thoroughly document clinical care and EMTALA compliance among this critically ill group before transfer.Mark Rose Carina Newton Benchaa Boualam Nancy Bogne Adam Ketchum Umang Shah Jordan Mitchell Safura Tanveer Tucker Lurie Walesia Robinson Rebecca Duncan Stephen Thom Quincy Khoi Tran 2019World Journal of Emergency Medicine2019,10,2:5
6Outcome predictors for severely brain-injured patients directly admitted or transferred from emergency departments to a trauma center显示文摘Dear editor,After sustaining severe traumatic brain injury(TBI),patients frequently require invasive mechanical ventilation(MV).However,up to 26%of patients require tracheostomy due to failure to wean from the ventilator.[1]The decision of when to perform tracheostomy is important as it balances the risk between avoiding prolonged MV and avoiding risk of tracheostomy.Early predictors for tracheostomy,i.e.,clinical factors when patients first present to an Emergency Department after trauma or when patient fi rst arrive at a regional trauma center,can help clinicians’medical decision-making process.Ryne Jenkins Nicholas A.Morris Bryce Haac Richard Van Besien Deborah MStein Neeraj Badjatia Amir Medic Gaurika Mester Quincy K.Tran 2020World Journal of Emergency Medicine2020,11,2:4
7Factors associated with refractory pain in emergency patients admitted to emergency general surgery显示文摘BACKGROUND: Oligoanalgesia in emergency departments (EDs) is multifactorial. A previousstudy reported that emergency providers did not adequately manage patients with severe paindespite objective findings for surgical pathologies. Our study aims to investigate clinical andlaboratory factors, in addition to providers’ interventions, that might have been associated witholigoanalgesia in a group of ED patients with moderate and severe pains due to surgical pathologies.METHODS: We conducted a retrospective study of adult patients who were transferred directlyfrom referring EDs to the emergency general surgery (EGS) service at a quaternary academic centerbetween January 2014 and December 2016. Patients who were intubated, did not have adequaterecords, or had mild pain were excluded. The primary outcome was refractory pain, which wasdefi ned as pain reduction <2 units on the 0–10 pain scale between triage and ED departure.RESULTS: We analyzed 200 patients, and 58 (29%) had refractory pain. Patients with refractory painhad signifi cantly higher disease severity, serum lactate (3.4±2.0 mg/dL vs. 1.4±0.9 mg/dL, P=0.001), and lessfrequent pain medication administration (median [interquartile range], 3 [3–5] vs. 4 [3–7], P=0.001), whencompared to patients with no refractory pain. Multivariable logistic regression showed that the number of painmedication administration (odds ratio [OR] 0.80, 95% confi dence interval [95% CI] 0.68–0.98) and ED serumlactate levels (OR 3.80, 95% CI 2.10–6.80) were signifi cantly associated with the likelihood of refractory pain.CONCLUSIONS: In ED patients transferring to EGS service, elevated serum lactate levelswere associated with a higher likelihood of refractory pain.William Gilliam Jackson FBarr Brandon Bruns Brandon Cave Jordan Mitchell Tina Nguyen Jamie Palmer Mark Rose Safura Tanveer Chris Yum Quincy K.Tran 2021World Journal of Emergency Medicine2021,12,1:2
8Post-hepatectomy liver regeneration in the context of bile acid homeostasis and the gut-liver signaling axis显示文摘Background:Liver regeneration following partial hepatectomy(PHx)is a complicated process involving multiple organs and several types of signaling networks.The bile acid-activated metabolic pathways occupy an auxiliary yet important chapter in the entire biochemical story.PHx is characterized by rapid but transient bile acid overload in the liver,which constitutes the first wave of proliferative signaling in the remnant hepatocytes.Bile acids trigger hepatocyte proliferation through activation of several nuclear receptors.Following biliary passage into the intestines,enterocytes reabsorb the bile acids,which results in the activation of farnesoid X receptor(FXR),the consequent excretion of fibroblast growth factor(FGF)19/FGF15,and its release into the enterohepatic circulation.FGF19/FGF15 subsequently binds to its cognate receptor,fibroblast growth factor receptor 4(FGFR4)complexed withβ-klotho,on the hepatocyte membrane,which initiates the second wave of proliferative signaling.Because some bile acids are toxic,the remnant hepatocytes must resolve the potentially detrimental state of bile acid excess.Therefore,the hepatocytes orchestrate a bile acid detoxification and elimination response as a protective mechanism in concurrence with the proliferative signaling.The response in part results in the excretion of(biotransformed)bile acids into the canalicular system,causing the bile acids to end up in the intestines.Relevance for patients:Recently,FXR agonists have been shown to promote regeneration via the gut-liver axis.This type of pharmacological intervention may prove beneficial for patients with hepatobiliary tumors undergoing PHx.In light of these developments,the review provides an in-depth account of the pathways that underlie post-PHx liver regeneration in the context of bile acid homeostasis in the liver and the gut-liver signaling axis.Lianne de Haan Sarah Jvan der Lely Anne-Loes K.Warps Quincy Hofsink Pim B.Olthof Mark J.de Keijzer Daniel A.Lionarons Lionel Mendes-Dias Bote G.Bruinsma Korkut Uygun Hartmut Jaeschke Geoffrey C.Farrell Narci Teoh Rowan Fvan Golen Tiangang Li Michal Heger 2018Journal of Clinical & Translational Research2018,4,1:2
