1Acupuncture's Role in Solving the Opioid Epidemic: Evidence, Cost-Effectiveness, and Care Availability for Acupuncture as a Primary, Non-Pharmacologic Method for Pain Relief and Management-White Paper 2017显示文摘The United States(U.S.) is facing a national opioid epidemic, and medical systems are in need of nonpharmacologic strategies that can be employed to decrease the public's opioid dependence. Acupuncture has emerged as a powerful, evidence-based, safe, cost-effective, and available treatment modality suitable to meeting this need. Acupuncture has been shown to be effective for the management of numerous types of pain conditions, and mechanisms of action for acupuncture have been described and are understandable from biomedical, physiologic perspectives. Further, acupuncture's cost-effectiveness can dramatically decrease health care expenditures, both from the standpoint of treating acute pain and through avoiding addiction to opioids that requires costly care, destroys quality of life, and can lead to fatal overdose. Numerous federal regulatory agencies have advised or mandated that healthcare systems and providers offer non-pharmacologic treatment options for pain. Acupuncture stands out as the most evidence-based, immediately available choice to fulfil these calls. Acupuncture can safely, easily, and cost-effectively be incorporated into hospital settings as diverse as the emergency department, labor and delivery suites, andneonatal intensive care units to treat a variety of commonly seen pain conditions. Acupuncture is already being successful y and meaningfully utilized by the Veterans Administration and various branches of the U.S. Military, in some studies demonstrably decreasing the volume of opioids prescribed when included in care.arthur yin fan david w.miller bonnie bolash matthew bauer john mcdonald sarah faggert hongjian he yong ming li amy matecki lindy camardella mel hopper koppelman jennifer a.m.stone lindsay meade john pang 2017Journal of Integrative Medicine2017,15,6:29
2施用生物炭和秸秆对石灰性褐土氮肥去向的影响显示文摘为明确秸秆直接还田和秸秆炭化为生物炭后施入土壤对氮肥转化(植株吸收、土壤残留及损失)的影响,采用大田微区试验,运用15N标记示踪技术,分析了石灰性褐土施用生物炭和秸秆后氮肥的去向,并阐明其影响机制。试验共设3个处理,单施化肥(NPK)、施化肥并施生物炭(NPK+B)以及施化肥并施秸秆(NPK+S)。结果表明:石灰性褐土上高粱植株当季的氮肥吸收率、土壤残留率和损失率分别是18.41%~24.94%、22.67%~35.47%和46.12%~52.40%;与NPK处理相比,NPK+B和NPK+S处理高粱植株的氮肥利用率分别降低2.20个百分点和6.53个百分点(P<0.05),土壤残留率分别增加5.58个百分点(P<0.05)和12.80个百分点(P<0.05),氮肥损失率分别降低3.40个百分点和6.28个百分点(P<0.05);施用秸秆显著提高了土壤活性有机碳含量、土壤微生物数量及代谢活性,增强了氮肥转化过程中土壤微生物对肥料氮的固定,从而减少氮肥损失。因此,与施用生物炭比较,秸秆直接还田是提高石灰性褐土氮肥有效性及秸秆资源合理利用的更有效途径。武爱莲 王劲松 董二伟 王立革 郭珺 南江宽 韩雄 Louis McDonald 焦晓燕 2019土壤学报2019,56,1:22

5不同水分条件下秸秆生物炭对高粱生长和养分含量的影响显示文摘【目的】研究不同水分条件下秸秆生物炭对高粱生长、养分含量以及土壤理化性质和养分含量的影响,以探明秸秆生物炭对高粱生长的作用效果。【方法】以高粱'晋杂34号'为供试作物,石灰性褐土为供试土壤进行盆栽试验。试验设3个水分处理,分别为正常供水,田间持水量的85%(W1);轻度胁迫,田间持水量的65%(W2);重度胁迫,田间持水量的45%(W3)。设5个秸秆生物炭添加量,分别占土壤干重的0、0.5%、1%、3%和6%。高粱出苗后70天调查株高,采集地上部(茎和叶),测定生物量、N、P、K、Ca、Mg、Fe、Mn、Cu和Zn的含量,同时采集土样测定pH值、EC、有机质、全氮、有效磷、速效钾、交换性Ca和Mg、有效Fe、Mn、Cu和Zn的含量。【结果】干旱胁迫显著降低了高粱生物量和株高;施用0.5%秸秆生物炭显著增加了重度干旱胁迫条件下高粱生物量,但是当施用量>1%时不同水分条件下高粱生物量和株高均显著降低。干旱胁迫降低了高粱P含量,增加了K、Ca、Mn和Zn的含量;秸秆生物炭提高了高粱K和Zn含量,降低了N、P和Mg的含量;随着水分含量的减少,作物收获后土壤有效Mn和有效Zn含量降低;添加生物炭显著提高了土壤速效K和有效Zn的含量,但是当施用量大于1%时,土壤交换性Mg、有效Fe和有效Mn的含量显著降低。【结论】供试条件下,施用0.5%秸秆生物炭能够提高高粱钾和锌的含量,促进干旱胁迫条件下(45%田间持水量)高粱的生长,但过量施用(>1%)会对高粱生长产生抑制作用。南江宽 王浩 王劲松 董二伟 武爱莲 焦晓燕 Louis McDonald 2018植物营养与肥料学报2018,24,4:11
6A Comprehensive Evaluation of Tourism Climate Suitability in Qinghai Province, China显示文摘Qinghai Province is an important component of the Qinghai-Tibet Plateau in China. Scientific evaluation of the suitability of Qinghai's climate for tourism can contribute to overcoming obstacles posed by climate on sustainable tourism development in Qinghai Province, including disparities between the low and high seasons, high altitude health concerns, and weather events. A tourism climate suitability evaluation model of the Qinghai-Tibet Plateau is constructed (Tourism Climate Suitability Index, or TCSI), and tourism climate suitability is comprehensively evaluated for Qinghai Province from climate data from 1960 to 2009. Results show that: (I) There is clear distributional characteristics of spatial-temporal variability of TCSI values in Qinghai Province. (II) Tourism climate suitability in Qinghai Province has significant seasonal and regional differences. The year is divided into a very suitable period (July and August), suitable tourism periods (from April and October), less suitable periods (From Nov to Mar). June to August is the most suitable tourism period in Qinghai. Qinghai Province is divided into five levels of tourism climate suitability: most suitable regions, very suitable regions, suitable regions, less suitable regions, and unsuitable region. (III) The key factor which influences regional differences in tourism climatic suitability is atmospheric oxygen. And the key factors which chiefly influence seasonal differences of tourism climate suitability are temperature and humidity, the wind chill factor, and barrier weather.TANG Chengcai ZHONG Linshen KRISTEN McDonald CHENG Shengkui 2012Journal of Mountain Science2012,9,3:11

9在结肠和直肠的癌症的淋巴节点收获: 当前的考虑显示文摘 The prognostic significance of identifying lymph node(LN) metastases following surgical resection for colon and rectal cancer is well recognized and is reflected in accurate staging of the disease.An established body of evidence exists,demonstrating an association between a higher total LN count and improved survival,particularly for node negative colon cancer.In node positive disease,however,the lymph node ratios may represent a better prognostic indicator,although the impact of this on clinical treatment has yet to be universally established.By extension,strategies to increase surgical node harvest and/or laboratory methods to increase LN yield seem logical and might improve cancer staging.However,debate prevails as to whether or not these extrapolations are clinically relevant,particularly when very high LN counts are sought.Current guidelines recommend a minimum of 12 nodes harvested as the standard of care,yet the evidence for such is questionable as it is unclear whether an increasing the LN count results in improved survival.Findings from modern treatments,including down-staging in rectal cancer using pre-operative chemoradiotherapy,paradoxically suggest that lower LN count,or indeed complete absence of LNs,are associated with improved survival;implying that using a specific number of LNs harvested as a measure of surgical quality is not always appropriate.The pursuit of a sufficient LN harvest represents good clinical practice;however,recent evidence shows that the exhaustive searching for very high LN yields may be unnecessary and has little in? uence on modern approaches to treatment.James R McDonald Andrew G Renehan Sarah T O’Dwyer Najib Y Haboubi 2012World Journal of Gastrointestinal Surgery2012,4,1:8
10武汉市养老院老年人生活质量及其影响因素显示文摘目的了解武汉市养老院老年人的生活质量状况及其影响因素。方法采用一般资料问卷和长期照顾生活质量量表对武汉市5所养老院107位老年人进行调查。结果武汉市养老院老人生活质量平均分偏低,为(6.22±1.42)分;得分最低的是'参加社会活动'和'与家人或朋友进行支持性沟通'。多因素分析显示影响养老院老年人生活质量的因素为自理能力、养老院居住的满意度、健康状况及养老院性质。结论武汉市养老院老年人生活质量有待提高。改善其生活质量应该鼓励老年人参加更多的社会活动;帮助建立较好的家庭社会支持系统;另外老年人的自理能力、养老院居住的满意度及健康状况应予关注。裴先波 高莹 张青 Tracey McDonald 2016中国老年学杂志2016,36,17:8
11硒的价态与浓度水平对6种植物种子发芽和根际生长的影响显示文摘本文研究了硒的价态(Se6+和Se4+)和浓度水平(0~100mgSe·L-1)对6种植物(大麦、小麦、花椰菜、萝卜、苜蓿和欧芹)种子萌发和根际生长特性的影响。结果表明,低浓度硒(<1mgSe·L-1)对种子发芽促进作用不明显,而高浓度硒(>4mgSe·L-1)则有显著抑制作用,不同种子对硒的抗性表现不同。根长和芽长的测定结果表明,低浓度对花椰菜和小麦种子生长具有显著促进作用,对欧芹种子表现出抑制作用。较高浓度(1~4mg·L-1)即对花椰菜、苜蓿和欧芹的根生长表现出抑制作用,高浓度对小麦、大麦和萝卜根生长有抑制作用,且使芽生长受到抑制的硒浓度高于根生长。比较价态,低硒时六价对花椰菜生长的促进作用显著高于四价,高硒时小麦和苜蓿对硒的抗性表现为六价硒强于四价硒,其余科属差异不显著。不同科属对硒的抗性为禾本科小麦和大麦最强,十字花科花椰菜和萝卜次之,豆科苜蓿较差,伞形科欧芹最差。毛晖 王朝辉 Graham Lyons Glenn McDonald 2011农业环境科学学报2011,30,10:8

15Wet Pressing Models to Reduce Energy Consumption in Papermaking显示文摘Improved wet pressing reduces the need for drying and consequently energy needed in papermaking. Accordingly, it is desirable to optimize wet pressing, but the process is very complex with many interacting variables. It is therefore desirable to employ a mathematical model that accounts for the major variables to estimate the effects of changes in equipment and operating variables. This paper descibes such a model called the Decreasing Permeability Model (DPM). Mill and pilot plant applications over a wide range of basis weights for paper and paper board are described.J.David McDonald Richard J.Kerekes Joe R.Zhao 2019Paper And Biomaterials2019,4,1:5

19Socio-Economic Impact Assessment of Intelligent Transport Systems显示文摘A general review of the socio-economic impact of the intelligent transport system (ITS) is pre-sented with a case study to demonstrate the data envelopment analysis method. Cost-benefit analyses are still the dominant method for evaluating ITS and other transport engineering projects, while cost effective analyses and multi-criteria appraisals are widely used to define and prioritize objectives by providing useful information for the most promising policy decisions. Both cost-benefit analyses and a data envelopment analysis method are applied to analyze the socio-economic impact of convoy driving systems. The main findings are that a convoy provides a worthwhile benefit-cost ratio when more than 30% of the traffics in the convoys and the traffic load exceeds 5500 vehicles/h for a three-lane motorway. The results also show that for a fixed percentage of convoys, increased demand will increase the data envelopment analysis method relative efficiency and that the neglect of certain output indicators of an ITS may result in underestimation of the system effects.隽志才 吴建平 Mike McDonald 2006Tsinghua Science and Technology2006,11,3:3
