| 1 | “文化诧异”现象研究显示文摘本文调查中国学生与外籍教师在课堂内外交往中所发生的“文化诧异”现象。以问卷形式共收集案例201件。按引起诧异的原因归纳成10类,如“不热情好客”,“对陌生人不必要的礼貌”等等。本文同时调查了中国学生对引起他们诧异的行为的价值评估。调查结果显示社团价值至上(东方文化)和个人价值至上(西方文化)的差异是引起诧异的主要原因。 | 朱维芳 Sarah Trenholm | 1997 | 外语教学与研究1997,29,1: | 75 |
| 2 | 淹水土壤有机酸积累与秸秆碳氮比及氮供应的关系显示文摘有机酸积累和毒害是稻田秸秆还田中受到广泛关注的问题。本文以水稻与小麦秸秆为材料,采用淹水培养研究了甲酸、乙酸、丙酸及丁酸在土壤中的积累及其与秸秆碳氮比、氮肥添加量的关系。结果表明,在不施用氮肥的情况下,随秸秆用量的增加,秸秆处理的有机酸积累均显著增多。与稻秸处理相比,麦秸处理的有机酸(尤其是丙酸)积累量显著较高,土壤溶液中NH4+浓度显著较低。加入尿素明显减少有机酸积累,促进CH4排放,但对CO2的排放无显著影响;氮素的影响在麦秸处理中表现的尤为明显。上述结果说明麦秸的高碳氮比增加了无机氮的生物固定,抑制有机酸向CH4转化,从而导致麦秸处理有机酸积累量高于稻秸处理。施用氮肥是减少麦秸还田后有机酸积累的有效措施之一,但此措施将可能促进CH4的排放。 | 单玉华 蔡祖聪 韩勇 Sarah E Johnson Roland J Buresh | 2006 | 土壤学报2006,43,6: | 68 |
| 3 | 美国临床肿瘤学会IV期非小细胞肺癌化疗的临床实践指南更新显示文摘本文旨在为IV期非小细胞肺癌患者的治疗提供更新版推荐。本文资料检索源自2002年以来公布的相关随机试验文献。此指南范围限于化疗与生物治疗。更新委员会对这些文献进行了总结并提供了推荐更新。162篇文献符合标准被纳入参考。本推荐基于可改善总生存期的治疗方法。仅改善无进展生存期的治疗方法推动了对毒性及生存质量的监测。对于体力状态评分为0分或1分患者的一线治疗,可推荐以铂类为基础的细胞毒性药物的两药联用。对铂类治疗有禁忌的患者,可采用非铂类细胞毒性两药联合。对于体力状态评分为2分的患者,单一细胞毒性药物即可。对于疾病进展或经过4个周期的治疗仍对治疗无反应的患者,应停止一线细胞毒性化疗。即使在6个周期后患者对治疗仍有反应,亦应停止两药细胞毒性化疗。对于伴有明确的表皮生长因子受体(epidermal growth factor receptor,EGFR)突变的患者,可推荐一线采用吉非替尼治疗;对于EGFR突变为阴性或不明确的患者,细胞毒性化疗更佳。除具有特定临床特征的患者外,可推荐贝伐单抗与卡铂-紫杉醇联用。对于通过免疫组化证实EGFR阳性的肿瘤患者,可推荐西妥昔单抗与顺铂-长春瑞滨联用。多西紫杉醇、厄洛替尼、吉非替尼或培美曲塞被推荐作为二线治疗。对于未曾接受过厄洛替尼或吉非替尼治疗的患者,可推荐厄洛替尼作为三线治疗。现有数据不足以推荐常规三线采用细胞毒性药物。已有的证据也不足以推荐常规应用分子标记物选择化疗。 | Christopher G.

| 7 | Acupuncture'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 | 2017 | Journal of Integrative Medicine2017,15,6: | 29 |
| 8 | Helicobacter pylori eradication therapy for functional dyspepsia: Systematic review and meta-analysis显示文摘AIM: To evaluate whether Helicobacter pylori(H. pylori) eradication therapy benefits patients with functional dyspepsia(FD).METHODS: Randomized controlled trials(RCTs) investigating the efficacy and safety of H. pylori eradication therapy for patients with functional dyspepsia published in English(up to May 2015) were identified by searching Pub Med, EMBASE, and The Cochrane Library. Pooled estimates were measured using the fixed or random effect model. Overall effect was expressed as a pooled risk ratio(RR) or a standard mean difference(SMD). All data were analyzed with Review Manager 5.3 and Stata 12.0.RESULTS: This systematic review included 25 RCTs with a total of 5555 patients with FD. Twenty-three of these studies were used to evaluate the benefits of H. pylori eradication therapy for symptom improvement; the pooled RR was 1.23(95%CI: 1.12-1.36, P < 0.0001). H. pylori eradication therapy demonstrated symptom improvement during long-term follow-up at ≥ 1 year(RR = 1.24; 95%CI: 1.12-1.37, P < 0.0001) but not during short-term follow-up at < 1 year(RR = 1.26; 95%CI: 0.83-1.92, P = 0.27). Seven studies showed no benefit of H. pylori eradication therapy on quality of life with an SMD of-0.01(95%CI:-0.11 to 0.08, P = 0.80). Six studies demonstrated that H. pylori eradication therapy reduced the development of peptic ulcer disease compared to no eradication therapy(RR = 0.35; 95%CI: 0.18-0.68, P = 0.002). Eight studies showed that H. pylori eradication therapy increased the likelihood of treatment-related side effects compared to no eradication therapy(RR = 2.02; 95%CI: 1.12-3.65, P = 0.02). Ten studies demonstrated that patients who received H. pylori eradication therapy were more likely to obtain histologic resolution of chronic gastritis compared to those who did not receive eradication therapy(RR = 7.13; 95%CI: 3.68-13.81, P < 0.00001).CONCLUSION: The decision to eradicate H. pylori in patients with functional dyspepsia requires individual assessment. | Li-Jun Du Bin-Rui Chen John J Kim Sarah Kim Jin-Hua Shen Ning Dai | 2016 | World Journal of Gastroenterology2016,22,12: | 30 |

| 12 | High Performance In Vivo Near-IR (>1 μm) Imaging and Photothermal Cancer Therapy with Carbon Nanotubes显示文摘Short single-walled carbon nanotubes(SWNTs)functionalized by PEGylated phospholipids are biologically non-toxic and long-circulating nanomaterials with intrinsic near infrared photoluminescence(NIR PL),characteristic Raman spectra,and strong optical absorbance in the near infrared(NIR).This work demonstrates the first dual application of intravenously injected SWNTs as photoluminescent agents for in vivo tumor imaging in the 1.0-1.4μm emission region and as NIR absorbers and heaters at 808 nm for photothermal tumor elimination at the lowest injected dose(70μg of SWNT/mouse,equivalent to 3.6 mg/kg)and laser irradiation power(0.6 W/cm2)reported to date.Ex vivo resonance Raman imaging revealed the SWNT distribution within tumors at a high spatial resolution.Complete tumor elimination was achieved for large numbers of photothermally treated mice without any toxic side effects after more than six months post-treatment.Further,side-by-side experiments were carried out to compare the performance of SWNTs and gold nanorods(AuNRs)at an injected dose of 700μg of AuNR/mouse(equivalent to 35 mg/kg)in NIR photothermal ablation of tumors in vivo.Highly effective tumor elimination with SWNTs was achieved at 10 times lower injected doses and lower irradiation powers than for AuNRs.These results suggest there are significant benefits of utilizing the intrinsic properties of biocompatible SWNTs for combined cancer imaging and therapy. | Joshua T.Robinson Kevin Welsher Scott M.Tabakman Sarah P.Sherlock Hailiang Wang Richard Luong Hongjie Dai | 2010 | Nano Research2010,3,11: | 20 |
| 13 | Influence of ellagic acid on prostate cancer cell proliferation:A caspase-dependent pathway显示文摘Objective:To evaluate the effect of allagic acid treatment on the cell viability of human prostate cancer cells.Methods:Ellagic acid(10-100 mol/L) treatment(48 h) of human prostate carcinoma PC3 cells was found to result in a dose-dependent inhibition of cell growth and apoptosis of PC3 cells as assessed by MTT assay,western blotting.flow cytometry and confocal microscopy.Results:We observed that ellagic acid treatment of PC3 cells resulted in a dose dependent inhibition of cell growth/cell viability.This ellagic acid caused cell growth inhibition was found to be accompanied by induction of apoptosis,as assessed by the cleavage of poly (ADP-ribose) polymerase(PARP) and morphological changes.Further,induction of apoptosis accompanied a decrease in the levels of antiapoptotic protein Bcl-2 and increase in proapoptotic protein Bax.thus shifting the Bax:Bcl-2 ratio in favor of apoptosis.Ellagic acid treatment of PC3 cells was also found to result in significant activation of caspases,as shown by the dose dependent decrease in the protein expression of procaspase-3,-6.-8 and -9.This ellagic acid-mediated induction of apoptosis was significantly(80%-90%) inhibited by the caspase inhibitor N-benzyloxycarbonyl-Val-Ala-Asp(OMe)-fluoromethylketone(Z-VAD-FMK).Thus these data suggested an essential role of caspases in ellagic acid-mediated apoptosis of PC3 cells.Conclusions:It is tempting to suggest that consumption of tropical pigmented fruits and vegetables could be an effective strategy to combat prostate cancer. | Arshi Malik Sarah Afaq Mohammad Shahid Kafil Akhtar Abdullah Assiri | 2011 | Asian Pacific Journal of Tropical Medicine2011,4,7: | 18 |

| 15 | The utility of point-of-care ultrasound in the assessment of volume status in acute and critically ill patients显示文摘BACKGROUND:Volume resuscitation has only been demonstrated to be effective in approximately fifty percent of patients.The remaining patients do not respond to volume resuscitation and may even develop adverse outcomes(such as acute pulmonary edema necessitating endotracheal intubation).We believe that point-of-care ultrasound is an excellent modality by which to adequately predict which patients may benefi t from volume resuscitation.DATA RESOURCES:We performed a search using PubMed,Scopus,and MEDLINE.The following search terms were used:fluid responsiveness,ultrasound,non-invasive,hemodynamic,fluid challenge,and passive leg raise.Preference was given to clinical trials and review articles that were most relevant to the topic of assessing a patient’s cardiovascular ability to respond to intravenous fl uid administration using ultrasound.RESULTS:Point-of-care ultrasound can be easily employed to measure the diameter and collapsibility of various large vessels including the inferior vena cava,common carotid artery,subclavian vein,internal jugular vein,and femoral vein.Such parameters are closely related to dynamic measures of fluid responsiveness and can be used by providers to help guide fluid resuscitation in critically ill patients.CONCLUSION:Ultrasound in combination with passive leg raise is a non-invasive,costand time-effective modality that can be employed to assess volume status and response to fluid resuscitation.Traditionally sonographic studies have focused on the evaluation of large veins such as the inferior vena cava,and internal jugular vein.A number of recently published studies also demonstrate the usefulness of evaluating large arteries to predict volume status. | Ali Pourmand Matthew Pyle David Yamane Kazi Sumon Sarah E.Frasure | 2019 | World Journal of Emergency Medicine2019,10,4: | 18 |

| 18 | 男男性行为人群同性恋身份自我认同与艾滋病危险因素的相关性显示文摘[目的]探索男男性接触者(MSM)对自己同性恋身份的认同及其与艾滋病相关危险因素的关系。[方法]使用统一设计的调查问卷,对利用'滚雪球'、'网络动员'等途径招募的151名MSM采用匿名面对面询问方式调查其自我认同、性行为、性伴网络、吸毒史和健康相关行为。[结果]消极自我认同的比例为56.29%(85/151)。文化程度与自我认同有关联性(χ2=8.022,P<0.05)。自认性取向为同性恋的积极自我认同比例高于自认性取向为双性恋和异性恋者(χ2=5.108,P<0.05)。不同自我认同和与男性首次性行为年龄、与异性结婚可能性、人类免疫缺陷病毒(HIV)抗体检测率、过去6个月有异性性伴/固定男性伴/多次男性伴等因素的关联有统计学意义(P值均<0.05),其中积极自我认同的MSM与男性首次性行为更多发生在20岁以前、与异性结婚可能性小、更易接受HIV检测服务、拥有固定男性伴比例高、拥有异性性伴和多次男性伴的比例小。[结论]MSM人群消极自我认同的比例较高,其无保护性交和多性伴较广泛地存在,主动求医进行HIV抗体检测率较低,感染HIV危险性和传播桥梁作用也更大。应广泛开展社会反歧视宣传,促进MSM积极自我认同,增进艾滋病预防服务利用,有效降低艾滋病传播的风险。 | 石国政 殷方兰 张永 宁镇 钟培松 Sarah Jane Steele Ted Myers | 2012 | 环境与职业医学2012,29,5: | 16 |
| 19 | Light-absorbing Particles in Snow and Ice: Measurement and Modeling of Climatic and Hydrological impact显示文摘Light absorbing particles(LAP, e.g., black carbon, brown carbon, and dust) influence water and energy budgets of the atmosphere and snowpack in multiple ways. In addition to their effects associated with atmospheric heating by absorption of solar radiation and interactions with clouds, LAP in snow on land and ice can reduce the surface reflectance(a.k.a., surface darkening), which is likely to accelerate the snow aging process and further reduces snow albedo and increases the speed of snowpack melt. LAP in snow and ice(LAPSI) has been identified as one of major forcings affecting climate change, e.g.in the fourth and fifth assessment reports of IPCC. However, the uncertainty level in quantifying this effect remains very high. In this review paper, we document various technical methods of measuring LAPSI and review the progress made in measuring the LAPSI in Arctic, Tibetan Plateau and other mid-latitude regions. We also report the progress in modeling the mass concentrations, albedo reduction, radiative forcing, and climatic and hydrological impact of LAPSI at global and regional scales. Finally we identify some research needs for reducing the uncertainties in the impact of LAPSI on global and regional climate and the hydrological cycle. | Yun QIAN Teppei J.YASUNARI Sarah J.DOHERTY Mark G.FLANNER William K.M.LAU MING Jing Hailong WANG Mo WANG Stephen G.WARREN Rudong ZHANG | 2015 | Advances in Atmospheric Sciences2015,32,1: | 16 |
| 20 | Uplift, climate and biotic changes at the Eocene-Oligocene transition in south-eastern Tibet显示文摘The uplift history of south-eastern Tibet is crucial to understanding processes driving the tectonic evolution of the Tibetan Plateau and surrounding areas.Underpinning existing palaeoaltimetric studies has been regional mapping based in large part on biostratigraphy that assumes a Neogene modernization of the highly diverse,but threatened,Asian biota.Here,with new radiometric dating and newly collected plant-fossil archives,we quantify the surface height of part of the south-eastern margin of Tibet in the latest Eocene(~34 Ma)to be^3 km and rising,possibly attaining its present elevation(3.9 km)in the early Oligocene.We also find that the Eocene–Oligocene transition in south-eastern Tibet witnessed leaf-size diminution and a floral composition change from sub-tropical/warm temperate to cool temperate,likely reflective of both uplift and secular climate change,and that,by the latest Eocene,floral modernization on Tibet had already taken place,implying modernization was deeply rooted in the Palaeogene. | Tao Su Robert A.
