| 1 | 庐枞盆地侵入岩的时空格架及其对成矿的制约显示文摘庐枞中生代火山盆地位于长江中下游断陷带内,地处扬子板块的北缘。庐枞盆地内火山岩和侵入岩分布广泛,包括龙门院、砖桥、双庙和浮山四组火山岩以及34个侵入岩体。本次工作在详细野外地质调查的基础上,结合作者已有的5个岩体(巴家滩岩体、城山岩体、花山岩体、黄梅尖岩体和枞阳岩体)年代学的研究工作,系统开展了盆地侵入岩体的年代学和时空分布特征研究。通过侵入岩锆石LA-ICP-MSU-Pb定年方法,本次研究确定庐枞盆地内15个主要侵入岩体的成岩时代分别为:黄屯岩体134.4±2.2Ma、岳山岩体132.7±1.5Ma、拔茅山岩体132.7±1.9Ma、尖山岩体132.0±1.3Ma、谢瓦泥岩体131.6±1.1Ma、龙桥岩体131.1±1.5Ma、焦冲岩体129.6±1.3Ma、土地山岩体127.4±2.8Ma、凤凰山岩体128.4±0.9Ma、罗岭岩体126.3±2.0Ma、龙王尖岩体126.5±1.5Ma、小岭岩体126.2±1.8Ma、大缸窑岩体125.9±1.3Ma、巴坛岩体125.1±1.1Ma、毛王庙岩体123.9±1.9Ma。从而得出庐枞盆地内侵入岩的成岩时代界于134~123Ma之间,属于早白垩世,并进一步将庐枞盆地内侵入岩划分成2期,其中早期侵入岩主要为二长岩和闪长岩类,主要分布在盆地北部,与龙门院旋回和砖桥旋回火山活动关系密切,岩体侵位受火山机构和北东向构造联合控制,成岩时代为134~130Ma;晚期侵入岩还可分为两类,第一类主要为正长岩类,分布在盆地南部,主要受盆地内火山机构和北北东向断裂控制,侵入活动与双庙旋回和浮山旋回火山岩浆活动相对应,成岩时代为129~123Ma;第二类主要为A型花岗岩,分布于盆地东南缘,成岩时代为126~123Ma,主要受区域北北东向大断裂控制,而与盆地火山机构无关。庐枞盆地内与岩浆岩有关的铁、铜、金、铅、锌、铀矿床可划分为3个成矿系列,其中砖桥旋回形成的二长岩类与罗河、泥河和龙桥等铁矿床、岳山铅锌矿床及井边和拔茅山铜矿床关系密切,双庙旋回形成的正长岩类与马口等铁矿床关系密切,而晚期的A型花岗岩与3440矿床等金、铀矿化关系密切。长江中下游地区燕山期存在145~136Ma、135~127Ma、126~123Ma等三期成岩(成矿)作用,庐枞盆地内侵入岩对应于该区域第二和第三期岩浆活动的产物,其形成时代明显晚于长江中下游成矿带断隆区内与斑岩型-矽卡岩型铜(铁)、金矿床有关的高钾钙碱性岩体(第一期)。庐枞盆地内侵入岩形成于区域岩石圈伸展的构造环境。 | 周涛发 范裕 袁峰 宋传中 张乐骏 钱存超 陆三明 David RC | 2010 | 岩石学报2010，26，9： | 181 |
| 2 | 宁芜盆地闪长玢岩的形成时代及对成矿的指示意义显示文摘宁芜盆地是长江中下游成矿带的重要组成部分和玢岩型铁矿床的主要产地,盆地内广泛产出闪长玢岩,这类岩体与铁矿床的形成关系密切,但其精确的成岩成矿时代及其形成构造背景的研究仍十分薄弱。本次工作在详细野外地质工作的基础上,系统开展了盆地内与铁矿床有关的7个闪长玢岩体的年代学研究,通过对闪长玢岩锆石LA-ICP-MS同位素定年方法,确定了盆地内主要闪长玢岩体,凹山岩体、陶村岩体、和尚桥岩体、东山岩体、白象山岩体、和睦山岩体和姑山岩体的成岩时代分别为130.2±2.0Ma、130.7±1.8Ma、131.1±1.5Ma、131.1±3.1Ma、130.0±1.4Ma、131.1±1.9Ma和129.2±1.7Ma。定年结果表明盆地内闪长玢岩成岩年龄均为130Ma左右,其成岩年龄可以近似代表铁矿床的成矿年龄。长江中下游地区存在145~136Ma、135~127Ma、126~123Ma三期成岩(成矿)作用,宁芜盆地内闪长玢岩是第二期岩浆活动的产物,其形成时代明显晚于长江中下游成矿带断隆区内与斑岩型-矽卡岩型铜(铁)、金矿床有关的高钾钙碱性岩体。宁芜盆地内闪长玢岩及玢岩型铁矿床形成于区域岩石圈伸展构造环境。 | 范裕 周涛发 袁峰 张乐骏 钱兵 马良 David RC | 2010 | 岩石学报2010，26，9： | 94 |

| 4 | 美国国立老化研究所与阿尔茨海默病协会诊断指南写作组:阿尔茨海默病痴呆诊断标准的推荐显示文摘由美国国立老化研究所(NIA)和阿尔茨海默病(AD)协会组织了一个工作组,负责修订1984年版AD痴呆的诊断标准。旨在确保修订后的标准具有足够的灵活性,既可供缺乏神经心理学测验、先进的影像技术和脑脊液检查措施的普通医务人员使用,也可供具备上述措施的科研、临床试验的专业研究者使用。新的标准广泛适用于各种原因的痴呆以及专门针对AD痴呆的标准,保留了1984年版标准中的“很可能的AD痴呆”的总体框架。在过去27年的经验基础上,工作组对临床诊断标准做了一些修改,保留了“可能的AD痴呆”的术语,但对其进行了更有针对性的重新定义。在科研用的“很可能的和可能的AD痴呆”的诊断标准中纳入了生物标志物证据。AD痴呆的核心临床标准仍将是临床实践中诊断的基础,但用生物标志物证据来提高AD痴呆诊断的病理生理学特异性也被人们寄予厚望。要实现AD痴呆的生物标志物诊断,还有许多工作摆在面前。 | McKhann GM Knopman DS Chertkow H Hyman BT Jack CR Jr Kawas CH Klunk WE Koroshetz WJ Manly J J Mayeux R Mohs RC Morris JC Rossor MN Scheltens P Carrillo MC Thies B Weintraub S Phelps CH 贾建平(译) 陆璐(译) 张逸驰(译) 黄丽(译) 韩阅(译) | 2012 | 中华神经科杂志2012，45，5： | 52 |
| 5 | Obstructive jaundice due to hepatobiliary cystadenoma or cystadenocarcinoma显示文摘Hepatobiliary cystadenomas (HBC) and cystadenocarci- nomas are rare cystic lesions. Most patients with these lesions are asymptomatic, but presentation with ob- structive jaundice may occur. The first patient presented with intermittent colicky pain and recurrent obstructive jaundice. Imaging studies revealed a polypoid lesion in the left hepatic duct. The second patient had recurrent jaundice and cholangitis. Endoscopic retrograde cholan- giopancreatography (ERCP) showed a cystic lesion at the confluence of the hepatic duct. In the third patient with intermittent jaundice and cholangitis, cholangioscopy re- vealed a papillomatous structure protruding into the left bile duct system. In the fourth patient with obstructive jaundice, CT-scan showed slight dilatation of the intrahe- patic bile ducts and dilatation of the common bile duct of 3 cm. ERCP showed filling of a cystic lesion. All patients underwent partial liver resection, revealing HBC in the specimen. In the fifth patient presenting with obstructive jaundice, ultrasound examination showed a hyperecho- genic cystic lesion centrally in the liver. The resection specimen revealed a hepatobiliary cystadenocarcinoma. HBC and cystadenocarcinoma may give rise to obstruc- tive jaundice. Evaluation with cross-sectional imaging techniques is useful. ERCP is a useful tool to differentiate extraductal from intraductal obstruction. | Deha Erdogan Olivier RC Busch Erik AJ Rauws Otto M van Delden Dirk J Gouma Thomas M van Gulik | 2006 | World Journal of Gastroenterology2006，12，35： | 26 |
| 6 | 黄连素片对钙离子通道的拮抗作用显示文摘本研究以药理学的方法检测了黄连素片对Ca2+通道的拮抗作用。结果表明黄连素片的水溶液能明显抑制Ca2+的内流.拮抗L型钙通道促进剂Bayk8644对钙通道的激活,从而降低SD大鼠胸主动脉的收缩性,40μg/ml浓度的黄连素片对Ca2+通道的抑制作用与10-8mol/L浓度的尼群地平相似。同时用Bayk8644使SD大鼠胸主动脉收缩后,黄连素片能以剂量依赖方式引发收缩动脉的自发性舒张。80mg/L浓度的黄连素片能使10-7mol/LBayk8644所致的收缩血管基本达到100%的舒张,其作用与10-7mol/L的尼群地平相似。说明黄连素片具有抑制电压控制的钙通道的作用,这可能是它具有心血管药理作用的基础。 | 司晓晨 Webb,RC | 1996 | 南京中医药大学学报1996，12，6： | 24 |

| 8 | Results of percutaneous sclerotherapy and surgical treatment in patients with symptomatic simple liver cysts and polycystic liver disease显示文摘AIM: To evaluate the results of the treatment of simple liver cysts (solitary and multiple) and polycystic liver disease (PLD) using percutaneous sclerotherapy and/or surgical procedures in a single tertiary referral centre. METHODS: Retrospective analysis of 54 patients referred for evaluation and possible treatment of simple liver cysts (solitary and multiple) and PLD, from January 1997 to July 2006. RESULTS: Simple liver cysts were treated in 41 pts (76/) with a mean size of 12.6 cm. The most common reason for referral was abdominal pain or discomfort (85/). Percutaneous sclerotherapy was performed as initial treatment in 30 pts, showing cyst recurrence in 6 pts (20/). Surgical treatment was initially performed in 11 pts with cyst recurrence in 3 pts (27/). PLD was treated in 13 pts (24/) with a mean size of the dominant cyst of 13 cm. Percutaneous sclerotherapy for PLD was performed in 9 pts with recurrence in 7 pts (77.8/). Surgical treatment for PLD was undertaken in 4 pts (30.8/) with recurrence in all. Eventually, 2 pts with PLD in the presence of polycystic kidney disease underwent liver-and kidney transplantation because of deterioration of liver and kidney function. CONCLUSION: The majority of patients with simple liver cysts and PLD are referred for progressive abdominal pain. As initial treatment, percutaneous sclerotherapy is appropriate. Surgical deroofing is indicated in caseof cyst recurrence after percutaneous sclerotherapy. However, the results of percutaneous sclerotherapy and surgical treatment for PLD are disappointing. Partial liver resection is indicated when there is suspicion of a pre-malignant lesion. | Deha Erdogan Otto M van Delden Erik AJ Rauws Olivier RC Busch Johan S Lameris Dirk J Gouma Thomas M van Gulik | 2007 | World Journal of Gastroenterology2007，13，22： | 15 |
| 9 | Immunoexpression of cyclooxygenase-2 in primary gastric carcinomas and lymph node metastases显示文摘AIM: To evaluate immunoexpression of cyclooxygenase-2 (COX-2) in primary gastric carcinomas and respective lymph node metastases. METHODS: Immunohistochemistry to analyze COX-2 expression was performed on tissue microarray slices obtained from 36 specimens of gastrectomy and satellite lymph nodes from patients with gastric carcinoma. RESULTS: Immunostaining was seen in most cases, and COX-2 expression was higher in lymph node me-tastases than in corresponding primary gastric tumors of intestinal, diffuse and mixed carcinomas, with a statistically signif icant difference in the diffuse histotype (P = 0.0108). CONCLUSION: COX-2 immunoexpression occurs frequently in primary gastric carcinomas, but higher expression of this enzyme is observed in lymph node metastases of the diffuse histotype. | Paulo RC Almeida Francisco VA Ferreira Cássio C Santos Francisco D Rocha-Filho Raul RP Feitosa Esther AA Falco Belise K Cavada Roberto CP Lima-Júnior Ronaldo A Ribeiro | 2012 | World Journal of Gastroenterology2012，18，8： | 14 |

| 17 | Experimental and numerical studies on new multi-dimensional earthquake isolation and mitigation device:Horizontal properties显示文摘Earthquake is a complex multi-dimensional excitation. Counter-measures of such multi-dimensional excitation on many critical structures,such as long-span structures and high-rise buildings,must be taken into account to avert the structural failure. Many types of earthquake mitigation or isolation devices for mitigating earthquake-induced effects in the horizontal direction have been proposed and applied to real applications. However,study on multi-dimensional earthquake isolation and mitigation devices for structures has been received much less attention. In this paper,a new multi-dimensional earthquake isolation and mitigation device was developed and tested. Effects of excitation frequency and environmental temperature on horizontal properties of this device were considered. At the same time,fatigue properties of the device under different amplitude horizontal excitations were also studied experimentally. The equivalent standard solid model which can effectively describe the effect of frequency and temperature on the horizontal properties of the device was proposed and verified. From the experimental results,it may be concluded that the multi-dimensional earthquake isolation and mitigation device owns fine energy dissipation and fatigue resistance capabilities. | XU ZhaoDong1, ZENG Xiao2, HUANG XingHuai1 & LU LiHeng1 1 RC&PC Key Laboratory of MOE, Southeast University, Nanjing 210096, China 2 Huaxin Past & Telecom Consulting and Designing Institute Co.

| 19 | Pulmonary infection control window in treatment of severe respiratory failure of chronic obstructive pulmonary diseases: a prospective, randomized controlled, multi-centred study显示文摘Background Early withdraw from invasive mechanical ventilation (MV) followed by noninvasive MV is a new strategy for changing modes of treatment. This study was conducted to estimate the feasibility and the efficacy of early extubation and sequential noninvasive MV commenced at beginning of pulmonary infection control window in patients with exacerbated hypercapnic respiratory failure caused by chronic obstructive pulmonary diseases (COPD). Methods A prospective, randomized controlled study was conducted in eleven teaching hospitals' respiratory or medical intensive care units in China. Ninety intubated COPD patients with severe hypercapnic respiratory failure triggered by pulmonary infection (pneumonia or purulent bronchitis) were involved in the study. When the pulmonary infection had been controlled by antibiotics and comprehensive therapy, the 'pulmonary infection control window (PIC window)' has been reached. Each case was randomly assigned to study group (extubation and noninvasive MV via facial mask immediately) or control group (invasive MV was received continuously after PIC window by using conventional weaning technique).Results Study group (n=47) and control group (n=43) had similar clinical characteristics initially and at the time of PIC window. Compared with control group, study group had shorter duration of invasive MV [(6.4±4.4) days vs (11.3±6.2) days, P=0.000], lower rate of ventilator associated pneumonia (VAP) (3/47 vs 12/43, P=0.014), fewer days in ICU [(12±8) days vs (16±11) days, P=0.047] and lower hospital mortality (1/47 vs 7/43, P=0.025).Conclusions In COPD patients requiring intubation and invasive MV for hypercapnic respiratory failure, which is exacerbated by pulmonary infection, early extubation followed by noninvasive MV initiated at the start of PIC window may decrease significantly the duration of invasive MV, the risk of VAP and hospital mortality. | Wang, C Zhan, QY Cao, ZX Wei, LQ Cheng, ZZ Liu, S Zhang, JL Chen, RC Luo, Q Niu, SF Zhu, L Wu, DW Fang, BM Wu, TH Wang, CZ Liu, YN | 2005 | Chinese Medical Journal2005，，19： | 6 |
