| 1 | 关岭及相关生物群沉积与生态环境的探讨显示文摘根据近年来对黔东南至滇东关岭、兴义、贞丰和罗平等地中-晚三叠世含海生爬行动物骨架和(或)深水海百合黑色岩系(通常所称黑色页岩)化石库的研究,现将该区岩石地层单位划分,以及这些黑色岩系化石库生物组合特征、时代、分布、沉积和古地理环境概括如下:1)在关岭—兴义地区中-晚三叠世(安尼期、拉丁期和早卡尼期)地层中,至少夹有3层、甚至4层含海生爬行动物的黑色岩系化石库(或黑色'页岩'化石库),自下而上产盘县生物群、兴义生物群和关岭生物群。云南罗平地区中三叠统关岭组中新发现的'罗平生物群'与盘县生物群层位大致相当。贞丰龙场赖石科组上部新挖掘出的30m厚产创口海百合、双壳类及菊石的黑色岩系,应该是研究地区最高层位的海相三叠纪黑色岩系,时代似属晚三叠世早卡尼期晚期;2)推测这些含海生爬行动物骨架的黑色岩系化石库是在印支造山运动影响下,伴随南盘江前陆盆地隆升和闭合,在扬子克拉通台地边缘所形成的一个或几个边缘凹陷、或边缘盆地之中形成的,这些凹陷或盆地形成之初,表层水充氧,且具有很好的食物链结构,有利于各类海生生物生活;后来的海平面上升至最大海泛期,以及由此引起缺氧和含硫化氢水位的上升,导致这些凹陷逐渐变成安静、滞流的死亡之海和黑色岩系化石库;3)关岭生物群产于晚三叠世卡尼期早期小凹组下段上部黑色岩系之中,是一个典型的在滞流、缺氧且海底没有食腐动物边缘局限盆地中所形成的黑色页岩化石库,以产大量海生爬行动物和深水假浮游海百合为特征,此外还有个别的两栖类和原始龟类发现;4)产于竹杆坡组近底部黑色岩系中的兴义生物群,以产大量肿肋龙类为特点,尤以个体较小的贵州龙最为常见,共生的还有多种鱼类化石,在生物组合和产出层位上,可与阿尔卑斯南部Meride灰岩所夹黑色含沥青页岩化石库对比,时代似应归属拉丁期早或中期;大量米虾在竹杆坡组近底部含贵州龙层的发现,推测兴义生物群可能形成于台地边缘早期并不缺氧,且具有理想食物链结构的浅水、超盐的凹陷或盆地之中。由于存在浮游生物—虾—贵州龙—欧龙—虾—浮游生物所组成的生态组合和食物链结构,从而为解释以肿肋龙类为代表的兴义生物群的繁衍和多生提供了依据;接踵而来的沉积速率下降和缺氧水位的上升,以及间歇性火山作用,导致该特有生态体系的崩溃和化石库的形成。根据对贞丰挽澜竹杆坡组底部首次发现的棘皮动物的化石库的研究,指出该化石库系由海星、细小蛇尾、底栖海百合茎、海胆和海参等5类棘皮动物化石和含贵州龙骨架碎片组成,其下为8m厚夹有薄层的骨层的凝缩层沉积,后者位于硬底之上。此种沉积和埋藏模式与德国上壳灰岩早拉丁期的棘皮动物化石库类似,是在近岸海水不太浅的内陆棚的环境下,由于风暴潮作用所形成的化石库,他们与在滞流、缺氧海底、通过化石聚集所形成的化石库是不同的;5)产盘县生物群的黑色岩系化石库主要见于盘县羊件和普安青山中三叠世(安尼期)关岭组中,与云南罗平地区的'罗平生物群'在层位及生物组合上大致相当,均以含大量混鱼龙、幻龙和欧龙,以及鱼类为特点,共生的还有大量节肢动物。所不同的是后者由于靠近滨岸,故而出现大量幼年期的鱼类以及虾类和鲎类化石,推测他们形成于靠近古陆或滨岸的台缘浅水表层充氧的正常、且有时超盐的凹陷之中,时代上早于阿尔卑斯南部安尼期/拉丁期比塞娄组;其集群死亡除因后期盆地滞流、缺氧外,可能还与风暴和火山作用有关。 | 汪啸风 陈孝红 程龙 王传尚 Bachmann G H Sander M Hagdorn H | 2009 | 古生物学报2009,48,3: | 24 |
| 2 | Upper-gastrointestinal bleeding secondary to peptic ulcer disease:Incidence and outcomes显示文摘AIM:To evaluate the incidence,surgery,mortality,and readmission of upper gastrointestinal bleeding(UGIB)secondary to peptic ulcer disease(PUD).METHODS:Administrative databases identified all hospitalizations for UGIB secondary to PUD in Alberta,Canada from 2004 to 2010(n=7079)using the International Classification of Diseases Codes(ICD-10).A subset of the data was validated using endoscopy reports.Positive predictive value and sensitivity with 95%confidence intervals(CI)were calculated.Incidence of UGIB secondary to PUD was calculated.Logistic regression was used to evaluate surgery,in-hospital mortality,and 30-d readmission to hospital with recurrent UGIB secondary to PUD.Co-variants accounted for in our logistic regression model included:age,sex,area of residence(i.e.,urban vs rural),number of Charlson comorbidities,presence of perforated PUD,undergoing upper endoscopy,year of admission,and interventional radiological attempt at controlling bleeding.A subgroup analysis(n=6356)compared outcomes of patients with gastric ulcers to those with duodenal ulcers.Adjusted estimates are presented as odds ratios(OR)with95%CI.RESULTS:The positive predictive value and sensitivity of ICD-10 coding for UGIB secondary to PUD were85.2%(95%CI:80.2%-90.2%)and 77.1%(95%CI:69.1%-85.2%),respectively.The annual incidence between 2004 and 2010 ranged from 35.4 to 41.2 per100000.Overall risk of surgery,in-hospital mortality,and 30-d readmission to hospital for UGIB secondary to PUD were 4.3%,8.5%,and 4.7%,respectively.Interventional radiology to control bleeding was performed in 0.6%of patients and 76%of these patients avoided surgical intervention.Thirty-day readmission significantly increased from 3.1%in 2004 to 5.2%in 2010(OR=1.07;95%CI:1.01-1.14).Rural residents(OR rural vs urban:2.35;95%CI:1.83-3.01)and older individuals(OR≥65 vs<65:1.57;95%CI:1.21-2.04)were at higher odds of being readmitted to hospital.Patients with duodenal ulcers had higher odds of dying(OR=1.27;95%CI:1.05-1.53),requiring surgery(OR=1.73;95%CI:1.34-2.23),and being readmitted to hospital(OR=1.54;95%CI:1.19-1.99)when compared to gastric ulcers.CONCLUSION:UGIB secondary to PUD,particularly duodenal ulcers,was associated with significant morbidity and mortality.Early readmissions increased over time and occurred more commonly in rural areas. | Samuel Quan Alexandra Frolkis Kaylee Milne Natalie Molodecky Hong Yang Elijah Dixon Chad G Ball Robert P Myers Subrata Ghosh Robert Hilsden Sander Veldhuyzen van Zanten Gilaad G Kaplan | 2014 | World Journal of Gastroenterology2014,20,46: | 21 |

| 4 | 中低收入国家癫痫过早死亡:国际抗癫痫联盟死亡率专业组系统评价显示文摘为了确定中低收入国家(Low-and middle-income countries,LMICs)癫痫相关的危险因素大小与过早死亡原因,专业组对来自LMICs(世界银行定义)的死亡率及癫痫相关文献报道进行系统检索,根据代表性,病例、诊断和死亡率的确证度对研究进行评估,并提取癫痫患者中的标准化死亡比(Standardized mortality ratios,SMR)和死亡率数据。研究调查了死亡的危险因素和原因。据估计,在高质量的群体研究中,癫痫患者年死亡率为19.8/1 000(9.7/1 000~45.1/1 000),加权中位SMR为2.6(1.3~7.2)。而临床队列研究显示的死亡率为7.1/1 000(1.6/1 000~25.1/1 000),加权中位SMR在男性中为5.0,女性中为4.5。在儿童和青少年、症状性癫痫或治疗依从性低的患者中发现了相对较高的SMR。群体研究显示,LMICs癫痫患者死亡的主要原因中直接归因于癫痫的平均比例死亡比(Proportional mortality ratio,PMR)为27.3%(5.0%~73.5%)。这些直接原因包括癫痫持续状态(报道的PMR为5.0%~56.5%)和癫痫猝死(Sudden unexpected death in epilepsy,SUDEP)(报道的PMR为1.0%~18.9%),与癫痫相关的间接死亡原因包括溺水、头部创伤和烧伤。LMICs癫痫患者的早亡率明显高于高收入国家。在LMICs,死亡率过高可能与患者难以获得医疗资源有关,例如发生癫痫持续状态时,以及包括溺水、头外伤和烧伤在内的可预防死因。这类过高的早亡率可以通过进行关于死亡风险的教育,提高治疗,包括抗癫痫药物治疗的可得性而大大降低。 | Levira F Thurman DJ Sander JW Hauser WA Hesdorffer DC Masanja H OdermattP Logroscino G Newton CR 陆璐 童馨 慕洁 | 2019 | 癫痫杂志2019,5,1: | 2 |
