Benefits of repeated air-root-pruning of seedlings when stepping up to progressively larger containers include excellent lateral root distribution immediately below the root collar and an exceptionally fibrous root ball. To evaluate long-term field performance of repeatedly air-root-pruned container stock, three plantings of swamp white oak (Quercus bicolor Willd.) 10 to 13 years old were located that also included bareroot planting stock. Initial and final stem diameter and height and above-ground green weights were determined on randomly selected trees at each site. On a site with a sandy, excessively drained, high pH soil, trees (age 10) from container stock were 1.5 times taller, 2.3 times larger in dbh, and 2.8 times greater in green weight than trees from bareroot stock which averaged only 2.9 m tall, 3.9 cm dbh, and 16.3 kg green weight. On a site with high clay, poor internal drainage, and frequent flooding, trees (age 12) from container stock were 1.4 times taller, 1.8 times larger in dbh, and 4.1 times greater in green weight than trees from bareroot stock which averaged 4 m tall, 7.3 cm dbh, and 28 kg green weight. On an upland site with deep loess soils, there was a trend for trees (age 13) from container stock to be only slightly larger than trees from bareroot stock with each stock type averaging 9.6 m tall, 20 cm dbh, and 177 kg green weight. Repeated air-root pruning produced lateral roots immediately below the root collar that resulted in large container stock with large well-balanced root systems that were competitive on harsh or less than ideal oak sites. Although the process is relatively labor intensive, propagation of repeatedly air-root-pruned container stock is readily adaptable internationally to locally available sources of organic matter and open-bottom containers.

目的据报道,在新辅助化疗过程中或之后行正电子发射体层摄影(PeT)示肿瘤18F-脱氧葡萄糖(FDG)摄取减低,可预测食管癌的病理学缓解。我们的目的是在前瞻性临床实验中应用标准化新辅助化疗方案来确定代谢反应是否可预测病理学缓解。方法一项非随机临床试验,包括接受治疗的潜在可治愈的食管癌病人。使用标准化化疗方案(奥沙利铂和5-氟尿嘧啶两个疗程)。化疗前行PeT/CT,且在第2疗程开始后24～28d复查PeT/CT。结果入选48例,平均年龄65岁,男性37例。应用最大标准摄取值(SUVmax)(42%)中位百分比降低来定义代谢反应,病理学缓解可见于71%(17/24)的代谢反应,无反应者为33%(8/24;P=0.009,敏感度68%,特异度70%)。病理学缓解可见于81%(13/16)具有完全代谢反应的病例和38%不完全代谢反应的病例(12/32;P=0.0042,敏感度52%,特异度87%),但无基于组织学的显著效应。结论代谢反应与病理学缓解之间具有显著相关性,但预测病理学缓解的准确性仍相对较低。要点①PeT/CT可预测食管癌病人其肿瘤对化疗的反应。②采用标准化化疗的前瞻性研究。③PeT/CT表现和疾病反应之间具有显著相关性。④然而预测病理学缓解的准确性仍相对较低。

计算科学是一门正在兴起的综合性学科,它依赖于先进的计算机及计算技术对理论科学、大型实验、观测数据、应用科学、国防以及社会科学进行模型化、模拟与仿真、计算等。特别是对极复杂系统进行模型与程序化,然后利用计算机给出严格理论及实验无法达到的过程数据或者直接模拟出整个复杂过程的演变或者预测过程的发展趋势。对基础科学、应用科学、国防科学、社会科学以及工程技术等的发展有着不可估量的科学作用与经济效益。其中,随着信息化和网络化的不断普及与深入,社会动态变化的速度和规模已经提高到一个前所未有的水平,计算科学在社会科学中的深入应用,即计算社会科学也将成为科研信息化发展中一个新的热点。本刊对《Science》2009年2月发表的一篇关于计算社会科学的文章《Computational Social Science》进行了摘编,该文由美国多个大学及研究机构的共15名研究人员共同编写,文章从计算社会科学的数据获取、研究方法及其制约因素,以及人才的培养等几个方面,描述了计算社会科学的发展、讨论了社会科学研究的特点等。其主要目的是想借此文向广大读者介绍计算社会科学这一学科理念,推动这一对于提高社会科学研究水平和规范性的研究方法在国内的发展,并以此进一步繁荣我国社会科学研究工作。

80年代初澳大利亚人Warren和marshall成功地从人胃中培养出螺旋样细菌,由于与空肠弯曲菌相似而称为幽门弯曲菌,之后根据其生物学特性命名为幽门螺杆菌。目前可以肯定,幽门螺杆菌(Hp)可引起慢性B型胃及胃、十二指肠溃疡。此外,Hp感染为胃腺癌及淋巴瘤的易患因素之一。近年来,许多研究提示,Hp与荨麻疹有关。亦有少数研究显示,Hp与红斑痤疮(Rosazea)、干燥综合征、雷诺综合征、系统性硬皮病、Schonlein-Henoch紫癜及Sweet综合征、萎缩性皮炎有关。值得注意的是,这些疾病都与胃肠道有某种共同联系,这些器官系统中存在原发疾病的临床免疫表现或伴随局灶感染症状。

世界核心医学期刊文摘（心脏病学分册） 2006年第11期2卷 3-4页

作者： Hock Ong M.e. Ornato J.P. edwards D.P. 任付先 Department of emergency Medicine Virginia Commonwealth University Medical Center 1250 E Marshall St Richmond VA 23298-0401 United States Dr.

Context: Only 1%to 8%of adults with out-of-hospital cardiac arrest survive to hospital discharge. Objective: To compare resuscitation outcomes before and after an urban emergency medical services(eMS) system switched from manual cardiopulmonary resuscitation(CPR) to load-distributing band(LDB) CPR. Design, Setting, and Patients: A phased, observational cohort evaluation with intention-to-treat analysis of 783 adults with out-of-hospital, nontraumatic cardiac arrest. A total of 499 patients were included in the manual CPR phase(January 1, 2001, to March 31, 2003) and 284 patients in the LDB-CPR phase(December 20, 2003, to March 31, 2005); of these patients, the LDB device was applied in 210 patients. Intervention: Urban eMS system change from manual CPR to LDB-CPR. Main Outcome Measures: Return of spontaneous circulation(ROSC), with secondary outcome measures of survival to hospital admission and hospital discharge, and neurological outcome at discharge. Results:Patients in the manual CPR and LDB-CPR phases were comparable except for a faster response time interval(mean difference, 26 seconds) and more eMS-witnessed arrests(18.7%vs 12.6%) with LDB. Rates for ROSC and survival were increased with LDB-CPR compared with manual CPR(for ROSC, 34.5%; 95%confidence interval[CI], 29.2%-40.3%vs 20.2%; 95%CI, 16.9%-24.0%; adjusted odds ratio[OR], 1.94; 95%CI, 1.38-2.72; for survival to hospital admission, 20.9%; 95%CI, 16.6%-26.1%vs 11.1%; 95%CI, 8.6%-14.2%; adjusted OR, 1.88; 95%CI, 1.23-2.86; and for survival to hospital discharge, 9.7%; 95%CI, 6.7%-13.8%vs 2.9%; 95%CI, 1.7%-4.8%; adjusted OR, 2.27; 95%CI, 1.11-4.77). In secondary analysis of the 210 patients in whom the LDB device was applied, 38 patients(18.1%) survived to hospital admission(95%CI, 13.4%-23.9%) and 12 patients(5.7%) survived to hospital discharge(95%CI, 3.0%-9.3%). Among patients in the manual CPR and LDB-CPR groups who survived to hospital discharge, there was no significant difference between groups in C

A search for the rare decay B^(0)→J/ψФis performed using Pp collision data collected with the LHCb dete-ctor at centre-of-mass energies of 7,8 and 13 TeV,corresponding to an integrated luminosity of9 *** significant signal of the decay is observed and an upper limitof 1.1x 10^(-7)at 90%confidence level is set on the branching fraction.
