1宁芜(南京-芜湖)盆地火山岩的年代学及其意义显示文摘宁芜盆地是长江中下游地区最重要的火山岩盆地之一,发育有龙王山、大王山、姑山和娘娘山4组以安山质火山岩为主的地层.通过对4组火山岩中熔岩的锆石LA-ICP MS同位素定年,得到各组火山岩形成的时间分别为:龙王山组(134.8±1.3)Ma、大王山组(132.2±1.6)Ma、姑山组(129.5±0.8)Ma和娘娘山组(126.6±1.1)Ma.宁芜盆地内火山岩皆形成于早白垩世,火山岩浆活动发生的起止时间约为135~127Ma,持续时间在8~10Ma左右.包括宁芜盆地在内的长江中下游地区各火山岩盆地均不存在侏罗纪火山岩浆活动.研究结果为进一步探讨和认识长江中下游及中国东部中生代构造-岩浆-成矿作用提供了新的年代学成果.周涛发 范裕 袁峰 张乐骏 钱兵 马良 杨西飞 David R COOKE 2011中国科学:地球科学2011,41,7:55
2Geochronology and significance of volcanic rocks in the Ning-Wu Basin of China显示文摘The Ning-Wu(Nanjing-Wuhu) Basin is one of the most important volcanic basins in the Middle-Lower Yangtze River Valley,eastern China.It consists of four volcanic units,i.e.,the Longwangshan,Dawangshan,Gushan,and Niangniangshan Formations.Their LA-ICP MS U-Pb zircon ages are 134.8±1.8,132.2±1.6,129.5±0.8,and 126.8±0.6 Ma,respectively.Results of this study indicate that all volcanic rocks in the Ning-Wu Basin were formed in the Early Cretaceous from 135 to 127 Ma,lasting 8-10 m.y.No Jurassic volcanic activities occurred in any of the volcanic basins of the Middle-Lower Yangtze River Valley,including the Ning-Wu Basin.These new chronological results provide significant evidence for further study of this region to improve our understanding of Mesozoic tectonic,magmatic,and metallogenic processes of eastern China.ZHOU TaoFa FAN Yu YUAN Feng ZHANG LeJun QIAN Bin MA Liang YANG XiFei David R COOKE 2011Science China Earth Sciences2011,54,2:33
3Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed.Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee 2014World Journal of Clinical Oncology2014,5,2:5

5相对于男性,女性进行冠状动脉造影产生的额外的心血管病风险与严重受损的冠状动脉血流储备,而非阻塞性疾病相关显示文摘与男性相比,女性的心血管病死亡率更高,但是阻塞性冠状动脉疾病(coronary artery disease,CAD)在女性中不太普遍。冠状动脉血流储备(coronary flow reserve,CFR)是大、小血管CAD和心肌缺血的综合测量指标,可识别出具有心血管病死亡风险的患者,但其在临床实践中不是常规测量的指标。该研究试图调查性别、CFR和血管造影CAD严重程度对不良心血管事件的影响。刘莉 叶鹏 Taqueti VR Shaw LJ Cook NR Murthy VL Shah NR Foster CR Hainer J Blankstein R Dorbala S Di Carli MF 2016中华高血压杂志2016,24,11:2

7高羊茅干草部分替代玉米和紫花苜蓿青贮饲料对奶牛消化、泌乳性能的影响显示文摘试验旨在研究高羊茅干草替代玉米或紫花苜蓿青贮对奶牛中性洗涤纤维(NDF)消化率、泌乳性能的影响。选取初产哺乳荷斯坦奶牛(产奶75±35 d)24头,经产荷斯坦奶牛(产奶68±19 d)40头,随机分成4组,共设置32个进料闸门,记录采食量。每组8个进料阀门,以1头牛为1个试验单位,每头牛试验过程中可接触8个进料闸门。试验用高羊茅干草(TF)取代玉米青贮饲料(CS)或紫花苜蓿青贮饲料(AS),试验设计为:33%AS和67%CS(空白组)、60%TF和40%AS(试验1组)、60%TF和40%CS(试验2组)、33%TF和67%CS(试验3组)。试验进行7周,前2周进行预饲。试验结果表明,各组间牛奶产量无显著差异,平均值为40.4 kg·d^(-1)。各组间牛奶中脂肪含量和浓度、蛋白质含量和浓度均无显著差异,平均值为1.58 kg·d^(-1)和3.94%、1.28 kg·d^(-1)和3.15%。与试验1组(22.1 kg·d^(-1))、试验3组(22.7 kg·d^(-1))相比,空白组的干物质摄入量最高,为24.5kg·d^(-1)。各组间总的干物质消化率无显著差异,平均值为66.2%。与试验2组(44.4%)、试验3组(45.3%)相比,空白组的NDF消化率较低,为37.8%,与试验1组(42.4%)相近。各组间奶牛体内NDF消化率(42.3%)与预估的NDF消化率(42.6%)相近。试验结果表明,饲喂高羊茅干草可提高饲料中NDF消化率,部分替代玉米和紫花苜蓿时对产奶量无显著影响,在市场价格较低时,可作为经济实用的奶牛饲料。Bender R W Lopes F Cook D E Combs D K 2016饲料博览2016,0,8:2
