| 3 | 高密度光释光测年揭示的距今约15~10ka黄土高原侵蚀事件显示文摘中国黄土堆积作为晚新生代陆相最好的古气候记录之一,得到了众多研究,其揭示的冰期-间冰期时间尺度的气候变化具有全球意义.但是,中国黄土研究中还有一些基本科学问题或假设没有得到证实,从而使一些研究结论受到质疑.为了进一步认识黄土堆积的连续性、绝对年龄和时间分辨率等问题,对黄土高原西北-东南方向上代表性的晚更新世-全新世黄土剖面进行了间距10cm的连续光释光年龄测定和古气候替代性指标测试,获得了108个绝对年龄数据.结果发现,在黄土高原塬区代表性的晚第四纪黄土剖面中存在约4~5ka的间断.这一直接的年代学证据表明,在千年时间尺度上黄土沉积是不连续的.新的年代证据指出,以前基于粉尘沉降模式获得的时间标尺是不准确的,从而使已发表的关于亚轨道时间尺度黄土古气候记录的研究工作需要重新审视.初步分析认为,黄土堆积的加剧侵蚀可能受气候变化控制. | 鹿化煜 Thomas Stevens 弋双文 孙雪峰 | 2006 | 科学通报2006，51，23： | 25 |
| 4 | An erosional hiatus in Chinese loess sequences revealed by closely spaced optical dating显示文摘Chinese loess deposits are some of the best continental records of palaeoclimatic and pa- laeoenvironmental changes in the late Cenozoic. Many investigations have shown that the long-time climate variations recorded by the loess-paleosol sequences can be correlated with global environ- mental changes. However,there are still some foundational questions concerning loess deposition that are not well answered,casting uncertainty on many previous conclusions,especially high-resolu- tion palaeoclimatic records. In this study,three typical loess-paleosol sections spanning the last glacial cy- cle were closely sampled for optically stimulated lu- minescence (OSL) dating and palaeoclimate inter- pretation along a northwest-southeast transect in Chinese Loess Plateau. Results show that there is a 4-5 ka hiatus in the typical loess deposits,and as a consequence suggests that the loess record is not continuous over millennial time scales. As such,pre- vious conclusions on climatic and environmental changes at millennial-centennial time scale,recon- structed through the loess record,should be reinves- tigated. The erosional hiatus may be forced by a pe- riod with strengthened East Asian winter monsoon and the less vegetation cover in the investigated sites. | LU Huayu Thomas Stevens YI Shuangwen SUN Xuefeng | 2006 | Chinese Science Bulletin2006，51，18： | 17 |

| 6 | One hundred and seventy-eight consecutive pancreatoduodenectomies without mortality:role of the multidisciplinary approach显示文摘BACKGROUND:Pancreatoduodenectomy offers the only chance of cure for patients with periampullary cancers.This,however,is a major undertaking in most patients and is associated with a significant morbidity and mortality.A multidisciplinary approach to the workup and follow-up of patients undergoing pancreatoduodenectomy was initiated at our institution to improve the diagnosis,resection rate,mortality and morbidity.We undertook the study to assess the effect of this approach on diagnosis,resection rates and short-term outcomes such as morbidity and mortality.METHODS:A prospective database of patients presenting with periampullary cancers to a single surgeon between April 2004 and April 2010 was reviewed.All cases were discussed at a multidisciplinary meeting comprising surgeons,gastroenterologists,radiologists,oncologists,radiation oncologists,pathologists and nursing staff.A standardized investigation and management algorithm was followed.Complications were graded according to the Clavien-Dindo classification.RESULTS:A total of 295 patients with a periampullary lesion were discussed and 178 underwent pancreatoduodenectomy (resection rate 60%).Sixty-one patients (34%) required either a vascular or an additional organ resection.Eighty-nine patients experienced complications,of which the commonest was blood transfusion (12%).Thirty-four patients (19%) had major complications,i.e.grade 3 or above.There was no in-hospital,30-day or 60-day mortality.CONCLUSIONS:Pancreatoduodenectomy can safely be performed in high-volume centers with very low mortality.The surgeon's role should be careful patient selection,intensive preoperative investigations,use of a team approach,and an unbiased discussion at a multidisciplinary meeting to optimize the outcome in these patients. | Jaswinder S Samra Raul Alvarado Bachmann Julian Choi Anthony Gill Michael Neale Vikram Puttaswamy Cameron Bell Ian Norton Sarah Cho Steven Blome Ritchie Maher Sivakumar Gananadha Thomas J Hugh | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，4： | 8 |
| 7 | 睾酮和良性前列腺增生症显示文摘由于医患双方对于男性迟发性腺功能减退症状的警觉,使得近期针对此类患者的睾酮治疗增多。但是考虑到睾酮治疗对前列腺的影响,尤其可能增加前列腺癌发病风险,促进了该方面的研究进展。出乎意料的是大量的回顾性或小样本随机研究提示睾酮治疗或可改善男性下尿路症状。虽然此改善的确切机理仍在争论中,但或许和代谢综合征密切相关。对于临床医生,这些研究的结果虽然让人期待,但是缺乏高等级证据支持。因此在诊断迟发性腺功能减退症或考虑睾酮治疗前,仍需对患者进行包括病史、体检和睾酮测量在内的全面临床检查。睾酮补充治疗可能导致尿潴留和加重下尿路症状,这些产品说明上标注的风险依然存在,应该在用药前向患者解释说明。 | Thomas R Jarvis Bilal Chughtai Steven A Kaplan | 2015 | Asian Journal of Andrology2015，17，2： | 7 |
| 8 | 烧伤治疗历史的回顾与展望显示文摘机体损伤涉及临床医学多学科,烧伤为平时和战时常见的一种组织损伤,它的修复包括维持机体的内环境稳定和不同深度的组织损伤后的修复全过程。近50年来,我国现代烧伤临床和研究发展迅速,业绩显著。虽然有不少创新成就,但由于对外交流还不够,尚未达到足够影响力,有些工作还不被人所知,我们应当一方面加强对外学术交流,扩大影响,另一方面,随时关注国际动态,做到知己知彼。为了使我国广大临床工作者系统了解美国烧伤临床和研究的概况,本刊组织了数位专家翻译由美国著名的烧伤专家David Heradon主编,近百余位专家撰写的Total Burn Care(第二版)2002年出版的美国最权威的烧伤治疗一书,将在本刊连续刊登,供同道们参考,该文有许多值得我们思考的地方。学诸专家之长,结合我国国情,走自己的创新之路,把我国烧伤治疗和研究推向新水平,为丰富国际烧伤医学宝库而奋斗。 | Steven Thomas Roberte Barrow David N Herndon 孙永华 | 2007 | 中华损伤与修复杂志(电子版)2007，2，3： | 6 |
| 9 | Clinical outcome of pediatric collagenous gastritis: Case series and review of literature显示文摘Collagenous gastritis (CG) is characterized by patchy subepithelial collagen bands. Effective treatment and the clinical and histological outcome of CG in children are poorly defined. The aim of this study is to summarize the published literature on the clinical outcome and response to therapy of pediatric CG including two new cases. We performed a search in Pubmed, OVID for related terms; articles including management and clinical and/or endo-histologic follow up information were included and abstracted. Reported findings were pooled in a dedicated database including the corresponding data extracted from chart review in our patients with CG. Twenty-four patients were included (17 females) with a mean age of 11.7 years. The clinical presentation included iron deficiency anemia and dyspepsia. The reported duration of follow up (in 18 patients) ranged between 0.2-14 years. Despite most subjects presenting with anemia including one requiring blood transfusion, oral iron therapy was only documented in 12 patients. Other treatment modalities were antisecretory measures in 13 patients; proton pump inhibitors (12), or histamine-2 blockers (3), sucralfate (5), prednisolone (6), oral budesonide in 3 patients where one received it in fish oil and triple therapy (3). Three (13%) patients showed no clinical improvement despite therapy; conversely 19 out of 22 were reported with improved symptoms including 8 with complete symptom resolution. Spontaneous clinical resolution without antisecretory, anti-inflammatory or gastroprotective agents was noted in 5 patients (4 received only supplemental iron). Follow up endohistopathologic data (17 patients) included persistent collagen band and stable Mononuclear cell infiltrate in 12 patients with histopathologic improvement in 5 patients. Neither collagen band thickness nor mononuclear cell infiltrate correlated with clinical course. Intestinal metaplasia and endocrine cell hyperplasia were reported (1) raising the concern of long term malignant transformation. In summary, CG in children is a chronic disease, typically with a variable clinical response and an indolent course that is distinct from the adult phenotype. Long term therapy usually inclused iron supplementation but cannot be standardized, given the chronicity of the disease, variability of response and potential for adverse events. | Nadia Mazen Hijaz Seth Steven Septer James Degaetano Thomas Mario Attard | 2013 | World Journal of Gastroenterology2013，19，9： | 5 |
| 10 | Evaluation of a point of care ultrasound curriculum for Indonesian physicians taught by fi rst-year medical students显示文摘BACKGROUND: The purpose of this study was to assess the short-term efficacy of a 4-week ultrasound curriculum taught by American first-year medical students to general practitioners working in public health care clinics, or puskesmas, in Bandung, Indonesia.METHODS: We performed a prospective, observational study of Indonesian health care practitioners from public clinics in Bandung, Indonesia. These practitioners were enrolled in a 4-week ultrasound training course taught by first-year American medical students. A total of six sessions were held comprising of 38 ultrasound milestones. A pre-course and post-course written exam and practical exam was taken by each participant.RESULTS: We enrolled 41 clinicians in the course. The average pre-course exam score was 35.2% with a 2.4% pass rate, whereas the average post-course exam score was 82.0% with a 92.7% pass rate. The average practical score at the completion of the course was 83.2%(SD=0.145) with 82.9% of the class passing(score above 75.0%).CONCLUSION: Our data suggests that first-year medical students can effectively teach ultrasound to physicians in Indonesia using a 4-week intensive ultrasound training course. Future studies are needed to determine the amount of training required for proficiency and to evaluate the physicians' perceptions of the student-instructors' depth of knowledge and skill in point of care ultrasound. | Jonathan B.Lee Christina Tse Thomas Keown Michael Louthan Christopher Gabriel Alexander Anshus Bima Hasjim Katrina Lee Esther Kim Luke Yu Allen Yu Shadi Lahham Steven Bunch Maili Alvarado Abdulatif Gari John C.Fox | 2017 | World Journal of Emergency Medicine2017，8，4： | 4 |

| 19 | Shoot and root traits in drought tolerant maize(Zea mays L.) hybrids显示文摘This study aimed to investigate the differences in shoot and root traits, and water use and water use efficiency(WUE) in drought tolerant(DT) maize(Zea mays L.) hybrids under full and deficit irrigated conditions. A two-year greenhouse study was conducted with four hybrids(one conventional hybrid, 33D53AM, two commercial DT hybrids, P1151 AM, N75H, and an experimental hybrid, Exp HB) grown under two water regimes(I_(100) and I_(50), referring to 100 and 50% of evapotranspiration requirements). Under water stress, the hybids P1151 AM, N75, and Exp HB showed more drought tolerance and had either greater shoot dry weight or less dry weight reduction than the conventional hybrid(33 D53 AM). However, these three hybrids responded to water stress using different mechanisms. Compared with the conventional hybrid, the two commercial DT hybrids(P1151 AM and N75H) had a smaller leaf area, shoot dry weight, and root system per plant. As a result, these hybrids used less water but had a higher WUE compared with the conventional hybrid. In contrast, the experimental hybrid(ExpHB) produced more shoot biomass by silking stage at both irrigation levels than all other hybrids, but it had relatively lower WUE. The hybrids demonstrated different drought response mechanisms that may require different irrigation management strategies. More investigation and validation are needed under field conditions and in different soil types. | ZHAO Jin XUE Qing-wu Kirk E Jessup HOU Xiao-bo HAO Bao-zhen Thomas H Marek XU Wen-wei Steven R Evett Susan A O'Shaughnessy David K Brauer | 2018 | Journal of Integrative Agriculture2018，17，5： | 3 |
| 20 | 用分子标记研究禾本科赖草属植物可溶性碳水化合物、色素积累和生长特性之间的遗传相关性(英文)显示文摘在低温条件下 ,冷季草的可溶性碳水化合物通常与紫色素的积累、生长的缓慢性及对寒冷的适应性具有相关性。Vrn_1基因对一年生冬性禾本科物种的春化、生长和可溶性碳水化合物的积累有重要作用。本研究以Ley muscinereus×L .triticoides的杂种F1开放授粉获得的F2 群体为材料 ,用 2 0 4个未定位的AFLP分子标记和几个基因组特定的与vrn_1相连锁的DNA标记检测了控制可溶性碳水化合物的积累、紫色素的积累和生长特性等几个数量性状的QTL。根据生长特性和适应性可将Leymuscinereus和L .triticoides区分开来。研究表明可溶性碳水化合物与紫色素的积累呈正相关 ,而且有关基因对这两种性状具有多效性。与之相类似 ,分蘖、叶发育、叶生长、草被剪后的再生长和地下茎的蔓延性这些性状之间也呈正相关 ,控制这些性状的基因具有多效性。但是可溶性碳水化合物的积累与生长的缓慢性无相关性。有几个分子标记包括与vrn_Xm1邻近的一个分子标记对叶可溶性碳水化合物的浓度和低温生长具有正效应。而与vrn_Ns1邻近的一个DNA标记对分蘖具有更加特别的效应。我们推测vrn_1对多年生赖草低温下叶可溶性碳水化合物的积累及生长习性具有数量效应。发现几个DNA标记对可溶性碳水化合物的积累及多个生长特性有较强的作用。 | 胡赞民 Steven R.
