| 1 | Altered trends in carbon uptake in China’s terrestrial ecosystems under the enhanced summer monsoon and warming hiatus显示文摘The carbon budgets in terrestrial ecosystems in China are strongly coupled with climate changes.Over the past decade,China has experienced dramatic climate changes characterized by enhanced summer monsoon and decelerated warming.However,the changes in the trends of terrestrial net ecosystem production(NEP)in China under climate changes are not well documented.Here,we used three ecosystem models to simulate the spatiotemporal variations in China's NEP during 1982–2010 and quantify the contribution of the strengthened summer monsoon and warming hiatus to the NEP variations in four distinct climatic regions of the country.Our results revealed a decadal-scale shift in NEP from a downtrend of–5.95 Tg C/yr^2(reduced sink)during 1982–2000 to an uptrend of 14.22 Tg C/yr^2(enhanced sink)during 2000–10.This shift was essentially induced by the strengthened summer monsoon,which stimulated carbon uptake,and the warming hiatus,which lessened the decrease in the NEP trend.Compared to the contribution of 56.3%by the climate effect,atmospheric CO2 concentration and nitrogen deposition had relatively small contributions(8.6 and 11.3%,respectively)to the shift.In conclusion,within the context of the global-warming hiatus,the strengthening of the summer monsoon is a critical climate factor that enhances carbon uptake in China due to the asymmetric response of photosynthesis and respiration.Our study not only revealed the shift in ecosystem carbon sequestration in China in recent decades,but also provides some insight for understanding ecosystem carbon dynamics in other monsoonal areas. | Honglin He Shaoqiang Wang Li Zhang Junbang Wang Xiaoli Ren Lei Zhou Shilong Piao Hao Yan Weimin Ju Fengxue Gu Shiyong Yu Yuanhe Yang Miaomiao Wang Zhongen Niu Rcmg Ge Huimin Yan Mei Huang Guoyi Zhou Yongfei Bai Zongqiang Xie Zhiyao Tang Bingfang Wu Leiming Zhang Nianpeng He Qiufeng Wang Guirui Yu | 2019 | National Science Review2019，6，3： | 24 |
| 2 | Determining "abnormal" levator hiatus distensibility using three-dimensional transperineal ultrasound in Chinese women显示文摘The dimension of the levator hiatus is a possible predictor of pelvic organ prolapse (POP). Thisretrospective study investigated 360 women who went to urogynecological clinic for pelvic floor discomfort.Levator hiatus dimensions were obtained by three-dimensional transperineal ultrasound and results werecompared between women with and without significantly objective prolapse (International Continence SocietyPOP quantification, grade 2 or higher). Receiver operating characteristic (ROC) curve analyses were performed todetermine valid screening index for detecting abnormal levator hiatus distensibility. Women with significantlyobjective prolapse had significantly higher levator hiatus dimensions than those without (all P 〈 0.001). ROCcurve analyses confirmed that hiatal area (HA) of 19.5 cm2 during Valsalva maneuver can be used as single-screening index for abnormal levator hiatus distensibility with sensitivity of 0.80 and specificity of 0.70. In thisstudy, we used a two-step method and achieved higher sensibility (0.80 vs. 0.87) without reducing specificity (0.70vs. 0.71) compared with a single-screening index method. As a result, we suggest that HA ≥ 19.5 cm2 duringValsalva maneuver is an indicator of abnormal levator hiatus distensibility in Chinese women and that the two-step method has higher sensitivity in detecting abnormal distensibility. | Chaoran Dou Qin Li Tao Ying Yulin Yan Xia Wang Bing Hu | 2018 | Frontiers of Medicine2018，12，5： | 21 |
| 3 | Changes in air temperature over China in response to the recent global warming hiatus显示文摘The 1998-2012 global wanning hiatus has aroused great public interest over the past several years.Based on the air temperature measurements from 622 meteorological stations in China,the temperature response to the global warming hiatus was analyzed at national and regional scales.We found that air temperature changed-0.221°C/10a during 1998-2012,which was lower than the long-term trend for 1960-1998 by 0.427°C/10a.Therefore,the warming hiatus in China was more pronounced than the global mean.Winter played a domi nant role in the nati on wide warming hiatus,con tributi ng 74.13%,while summer contributed the least among the four seasons.Furthermore,the warming hiatus was spatial heterogeneous across different climate conditions in China.Comparing the three geographic zones,the monsoon region of eastern China,arid region of northwestern China,and high frigid region of the Tibetan Plateau,there was significant cooling in eastern and northwestern China.In eastern China,which contributed 53.79%,the trend magnitudes were 0.896°C/10a in winter and 0.134°C/10a in summer.In the Tibeta n Plateau,air temperature in creased by 0.204°C/10a,indicating a lack of a significant warming hiatus.More broadly,the warming hiatus in China may have been associated with the negative phase of PDO and reduction in sunspot numbers and total solar radiation.Finally,although a warming hiatus occurred in China from 1998 to 2012,air temperature rapidly increased after 2012 and will likely to continuously warm in the next few years. | DU Qinqin ZHANG Mingjun WANG Shengjie CHE Cunwei MA Rong MA Zhuanzhuan | 2019 | Journal of Geographical Sciences2019，29，4： | 9 |
| 4 | Os isotope dating and growth hiatuses of Co-rich crust from central Pacific显示文摘Up to now, accurate determination of the growth age and hiatuses of the Co-rich crust is still a difficult work, which constrains the researches on the genesis, growth process, controlling factors, regional tectonics, paleo-oceanographic background, etc. of the Co-rich crust. This paper describes our work in determining the initial growth age of the Co-rich crust to be of the late Cretaceous Campanian Stage (about 75-80 Ma), by selecting the Co-rich crust with clear multi-layer structures in a central Pacific seamount for layer-by-layer sample analysis and using a number of chronological methods, such as Co flux dating, dating by correlation with 187Os/188Os evolution curves of seawater, and stratigraphic divi- sion by calcareous nannofossils. We have also discovered growth hiatuses with different time intervals in the early Paleocene, middle Eocene, late Eocene and early-middle Miocene, respectively. These re- sults have provided an important age background for further researches on the Co-rich crust growth process and the paleo-oceanographic environment evolution thereby revealed in the said region. | LI JiangShan FANG NianQiao QU WenJun DING Xuan GAO LianFeng WU ChangHang ZHANG ZhenGuo | 2008 | Science China Earth Sciences2008，51，10： | 6 |
| 5 | 1960-2013年黄土高原地区气温变化对Hiatus现象的响应显示文摘为研究黄土高原地区对全球变暖“停滞”现象是否存在响应,运用1960-2013年黄土高原地区114气象站点月平均气温、平均最高气温、平均最低气温数据,对数据进行了均一化的检验和订正,使用线性趋势法、距平值法、Mann-Kendall趋势检验法分析了黄土高原地区近54 a气温的变化特征,并分析了黄土高原地区气温变化对Hiatus现象的响应过程。结果显示:(1)1960-2013年平均气温升温显著,升温率为0.27℃/10 a,平均最低气温升温率(0.35℃/10 a)>平均最高气温(0.297℃/10 a)>平均气温(0.27℃/10 a),空间上平均气温、平均最高气温升温率由东南向西北增加;(2)1960s以来平均气温、平均最低气温、最高气温后一个年代气温距平值大于前一个年代,平均气温和平均最低气温冬季升温最显著,平均最高气温秋季升温最显著;(3)黄土高原地区在Hiatus期间出现升温减缓趋势,期间气温变化倾向率为-0.33℃/10 a,Hiatus期间气温降低是由冬季气温显著降低引起的,夏季气温呈不显著升高趋势。平均最低与最高气温也在Hiatus期间出现升温减缓趋势,全球气温变化的Hiatus现象在黄土高原地区有明显的区域响应,黄土高原地区处于北半球干旱区与湿润区的过渡带,是气候变化的敏感带,其气温变化一定程度上证实了1998-2013年全球升温减缓的趋势是存在的。 | 张耀宗 张勃 刘艳艳 张多勇 | 2020 | 水土保持研究2020，27，4： | 6 |
| 6 | Could CMIP6 climate models reproduce the early-2000s global warming slowdown?显示文摘The unexpected global warming slowdown during 1998–2013 challenges the existing scientific understanding of global temperature change mechanisms,and thus the simulation and prediction ability of state-of-the-art climate models since most models participating in phase 5 of the Coupled Model Intercomparison Project(CMIP5)cannot simulate it.Here,we examine whether the new-generation climate models in CMIP6 can reproduce the recent global warming slowdown,and further evaluate their capacities for simulating key-scale natural variabilities which are the most likely causes of the slowdown.The results show that although the CMIP6 models present some encouraging improvements when compared with CMIP5,most of them still fail to reproduce the warming slowdown.They considerably overestimate the warming rate observed in 1998–2013,exhibiting an obvious warming acceleration rather than the observed deceleration.This is probably associated with their deficiencies in simulating the distinct temperature change signals from the human-induced long-term warming trend and/or the three crucial natural variabilities at interannual,interdecadal,and multidecadal scales.In contrast,the 4 models that can successfully reproduce the slowdown show relatively high skills in simulating the long-term warming trend and the three keyscale natural variabilities.Our work may provide important insight for the simulation and prediction of near-term climate changes. | Meng WEI Qi SHU Zhenya SONG Yajuan SONG Xiaodan YANG Yongqing GUO Xinfang LI Fangli QIAO | 2021 | Science China Earth Sciences2021，64，6： | 5 |
| 7 | Changes in Aridity in Response to the Global Warming Hiatus显示文摘The global warming slowdown or warming hiatus, began around the year 2000 and has persisted for nearly 15 years. Most studies have focused on the interpretation of the hiatus in temperature. In this study, changes in a global aridity index(AI) were analyzed by using a newly developed dynamical adjustment method that can successfully identify and separate dynamically induced and radiatively forced aridity changes in the raw data. The AI and Palmer Drought Severity Index produced a wetting zone over the mid-to-high latitudes of the Northern Hemisphere in recent decades. The dynamical adjustment analysis suggested that this wetting zone occurred in response to the global warming hiatus. The dynamically induced AI(DAI) played a major role in the AI changes during the hiatus period,and its relationships with the North Atlantic Oscillation(NAO), Pacific Decadal Oscillation(PDO), and Atlantic Multi-decadal Oscillation(AMO) also indicated that different phases of the NAO, PDO, and AMO contributed to different performances of the DAI over the Northern Hemisphere. Although the aridity wetting over the mid-to-high latitudes may relieve long-term drying in certain regions, the hiatus is temporary, and so is the relief. Accelerated global warming will return when the NAO, PDO, and AMO revert to their opposite phases in the future, and the wetting zone is likely to disappear. | Xiaodan GUAN Jianping HUANG Ruixia GUO | 2017 | Journal of Meteorological Research2017，31，1： | 5 |
| 8 | Abrupt temperature change and a warming hiatus from 1951 to 2014 in Inner Mongolia, China显示文摘An abrupt temperature change and a warming hiatus have strongly influenced the global climate.This study focused on these changes in Inner Mongolia, China. This study used the central clustering method, Mann-Kendall mutation test and other methods to explore the abrupt temperature change and warming hiatus in three different temperature zones of the study region based on average annual data series.Among the temperature metrics investigated, average minimum temperature(Tnav) shifted the earliest,followed by average temperature(Tnv) and average maximum temperature(Txav). The latest change was observed in summer(1990 s), whereas the earliest was observed in winter(1970 s). Before and after the abrupt temperature change, Tnav fluctuated considerably, whereas there was only a slight change in Txav.Before and after the abrupt temperature change, the winter temperature changed more dramatically than the summer temperature. Before the abrupt temperature change, Tnav in the central region(0.322°C/10 a)and west region(0.48°C/10 a) contributed the most to the increasing temperatures. After the abrupt temperature change, Tnav in winter in the central region(0.519°C/10 a) and in autumn in the west region(0.729°C/10 a) contributed the most to the temperature increases. Overall, in the years in which temperature shifts occurred early, a warming hiatus also appeared early. The three temperature metrics in spring(1991)in the east region were the first to exhibit a warming hiatus. In the east region, Txav displayed the lowest rate of increase(0.412°C/a) in the period after the abrupt temperature change and before the warming hiatus,and the highest rate of increase after the warming hiatus. | MA Long LI Hongyu LIU Tingxi LIANG Longteng | 2019 | Journal of Arid Land2019，11，2： | 3 |

| 10 | Osmium isotope of the Co-rich crust from seamount Allison, central Pacific and its use for determination of growth hiatus and growth age显示文摘Based on its microstructure, Co-rich crust A1-1 from seamount Allison, central Pacific, was scraped at averaged interval of 1.3 mm to measure osmium isotopic composition, and subsequently to establish the 187Os/188Os profile of scraping section of the crust. By observing the variation of 187Os/188Os under 10Be chronology and matching it to the well-known seawater Os isotope evolution of the past 40 Ma, two growth hiatuses (H1 and H2) occurring in the periods respectively between 13.6 and 29.6 Ma and between 8 and 9.8 Ma in the crust were recognized. According to the two hiatuses, the dating scheme for each scraped layer of the crust was suggested. For the upper layers younger than 6.8Ma, their growth ages were calibrated under 10Be chronology; for the lower layers older than 6.8Ma, their growth ages were obtained from 187Os/188Os evaluation curve by linear interpolation. Hereby, the age for the most inner layer of the crust was determined to be 39.5 Ma. H1 and H2 exactly correspond to the boundary between phosphatization and non-phosphatization and volcanic ash layer in the crust, respectively. | MENG XianWei LIU YanGuang QU WenJun SHI XueFa | 2008 | Science China Earth Sciences2008，51，10： | 2 |
| 11 | The relationship between the growth process of the ferromanganese crusts in the Pacific seamount and Cenozoic ocean evolvement显示文摘Base on the Os isotope stratigraphy together with the empirical growth rate models using Co concentrations, the growth ages of the ferromanganese crusts MHD79 and MP3D10 distributed in the seamount of Pacific are confirmed. Through the contrast and research on the previous achievements including ODP Leg 144 and the crusts CD29-2, N5E-06 and N1-15 of the seamount of the Central Pacific, the uniform five growth and growth hiatus periods of them are found, and closely related to the Cenozoic ocean evolvement process. In the Paleocene Carbon Isotope Maximum (PCIM), the rise of the global ocean productivity promoted the growth of the seamount crust; the first growth hiatus (I) of the ferromanganese crust finished. In the Paleocene-Eocene Thermal Maximum (PETM), though the vertical exchange of seawater was weakened, the strong terrestrial chemical weathering led to the input of a great amount of the terrigenous nutrients, which made the bioproductivity rise, so there were no crust hiatuses. During 52-50 Ma, the Early Eocene Optimum Climate (EECO), the two poles were warm, the latitudinal temperature gradient was small, the wind-driven sea circulation and upwelling activity were weak, the terrestrial weathering was also weakened, the open ocean bioproductivity decreased, and the ferromanganese crust had growth hiatus again (II). From early Middle Eocene-Late Eocene, Oligocene, it was a long-term gradually cooling process, the strengthening of the sea circulation and upwelling led to a rise of bioproductivity, and increase of the content of the hydrogenous element Fe, Mn and Co and the biogenous element Cu, Zn, so that was the most favorable stage for the growth of ferromanganese crust (growth periods III and IV) in the studied area. The hiatus III corresponded with the Eocene-Oligocene boundary, is inferred to relate with the global climate transformation, celestial body impact event in the Eocene-Oligocene transition. From the early to the middle Miocene, a large-scale growth hiatus (hiatus period IV) of the ferromanganese crust in the studied area is inferred to relate with temporary warm up climate and ephemeral withdrawal of Antarctic bottom water in the early Miocene. After that, the Antarctic ice sheets extended, the bottom water circumfluence strengthened, the ocean fertility increased, and the once interrupted crust continued to grow in the late Miocene (growth period V). | DING Xuan GAO LianFeng FANG NianQiao QU WenJun LIU Jian LI JiangShan | 2009 | Science China Earth Sciences2009，52，8： | 2 |
| 12 | Stable Isotope Evidence for Recent Global Warming Hiatus显示文摘Global mean surface air temperature(SAT)has remained relative stagnant since the late 1990s,a phenomenon known as global warming hiatus.Despite widespread concern and discussion,there is still an open question about whether this hiatus exists,partly due to the biases in observations.The stable isotopic composition of precipitation in mid-and high-latitude continents closely tracks change of the air temperature,providing an alternative to evaluate global warming hiatus.Here we use the long-term precipitation δ^18O records available to investigate changes in SAT over the period 1970–2016.The results reveal slight decline in δ^18O anomaly from 1998 to 2012,with a slope of?0.0004‰decade?1 which is significantly different from that of pre-1998 interval This downwardδ18O anomaly trend suggests a slight cooling for about?0.001℃ decade?1,corroborating the recent hiatus in global warming.Our work provides new evidence for recent global warming hiatus and highlights the potential of utilizing precipitation isotope for tracking climate changes. | Rui Wang Zhongfang Liu | 2020 | Journal of Earth Science2020，31，2： | 2 |
| 13 | Silurian integrative stratigraphy and timescale of China显示文摘Silurian is a period with the shortest duration in Phanerozoic except for the Neogene and Quaternary. It represents an important and unique interval when the biotic diversity recovered quickly after the end-Ordovician mass extinction, different paleoplates or terranes conjoined, big oceans disappeared or narrowed, climate and sea level changed frequently, global biotic provincialism became weaker, some primitive plants started to occupy the land. Silurian is also the first system of which all the chronostratigraphic stratotypes(i.e. the GSSPs) including four series and seven stages were established by the International Subcommission on Silurian Stratigraphy(ISSS). Nonetheless, during the post-GSSP studies conducted by ISSS in the middle1980 s, some Silurian GSSPs were found to have some congenital defects such as no index fossils available that hinder the high resolution subdivision and correlation on a regional or global scale. In this paper, based on the latest development of Silurian study in China, the progress in biostratigraphy, chronostratigraphy, event stratigraphy(such as facies differentiation, heterochrony of black shales, marine red beds, carbonate rocks and reefs), chemostratigraphy, and tectonic stratigraphy(e.g., widespread of the late Silurian rocks in South China and its tectonic implication) are systematically summarized. Some existing problems and the areas to be focused in future work are also discussed. It is suitable for chronostratigraphic study to concentrate not only on the boundary but also doing multidisciplinary analysis on the biotic, chemical, magnetic, environmental, and chronologic aspects, in order to enhance the reliability and the potential for regional and global correlation of a certain GSSP.Some important achievements are expected in these areas in the Silurian study in China:(1) ecostratigraphy and basin analysis of the Llandovery, and the correlation of integrative stratigraphy with a high resolution;(2) establishment of the Wenlock to Pridoli chronostratigraphic framework;(3) the chemo-and magnetic stratigraphy and the age of some key intervals and horizons;(4)further investigation on paleogeography and plate tectonics; and(5) origin and early evolution of the terrestrial ecosystem. Some new breakthroughs might occur in the restudy on some of those problematic GSSPs of some particular series and stages. | Jiayu RONG Yi WANG Renbin ZHAN Junxuan FAN Bing HUANG Peng TANG Yue LI Xiaole ZHANG Rongchang WU Guangxu WANG Xin WEI | 2019 | Science China Earth Sciences2019，62，1： | 2 |

Finally a quantitativecurve of Late Permian relative sea-level change in the Ziyun area is presented with timecoordinates. | Zhou Yaoqi Lu Yongchao Li Sitian and Wang Hongzhen China University of Petroleum, Dongying, Shandong China University of Geosciences, Beijing Fei Zhenbi | 1997 | Acta Geologica Sinica(English Edition)1997，71，3： | 2 |
| 15 | 沉默短片断的实质的发生内视镜地在一个成年日本主要照顾惯例怀疑了食道的组织变形显示文摘 AIM: To determine the incidence and characteristics of endoscopically suspected esophageal metaplasia (ESEM) in a primary adult care institution. METHODS: Eight hundred and thirty two consecutive individuals (mean age, 67.6 years) undergoing upper gastrointestinal endoscopy between January 2009 and December 2010 were included in this study. The diagnosis of ESEM was based on the criteria proposed by the Japan Esophageal Society, and was classified as long segment ESEM (3 cm or more) or short segment ESEM (< 3cm). Short segment ESEM was further divided into circumferential and partial types. Age, gender, hiatus hernia, esophagitis, gastroesophageal reflux disease (GERD)-suggested symptoms, and antacid medications were recorded as background factors. Esophagitis was graded according to the Los Angeles classification. Hiatus hernia was divided into absent and at least partially present. RESULTS: Long and short segment ESEM were found in 0 and 184 (22.1%) patients, respectively (mean age of short segment ESEM patients, 68.3 years). Male gender and hiatus hernia were shown to be signifi cant factors affecting short segment ESEM by both univariate (P = 0.03 and P = 9.9x10-18) and multivariate [Odds ratio (OR) = 1.45; P = 0.04, and OR = 43.3; P = 1.5x10-7)] analyses. Two thirds of patients with short segment ESEM did not have GERD-suggested symptoms. There was no correlation between short segment ESEM and GERD-suggested symptoms. | Shouji Shimoyama Toshihisa Ogawa Toshiyuki Toma Kousuke Hirano Shuichi Noji | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，2： | 1 |
| 16 | Warming hiatus-and evergreen conifers in Altay-Sayan Region,Siberia显示文摘'Warming hiatus' occurred in the AltaySayan Mountain Region, Siberia in c. 1997–2014. We analyzed evergreen conifer(EGC) stands area(satellite data) and trees(Siberian pine, Pinus sibirica Du Tour, Siberian fir, Abies sibirica Ledeb.) growth increment(dendrochronology data) response to climate variables before and during the hiatus. During the hiatus, EGC area increased in the highlands(>1000 m)(+30%), whereas at low and middle elevations(<1000 m. a.s.l.) the EGC area decreased(-7%). The EGC area increase was observed on the rain-ward northwest slopes mainly. In highlands, EGC area increase mainly correlated with summer air temperature, whereas at low and middle elevations EGC area decrease correlated with drought index SPEI and vapor pressure deficit(VPD). EGC mortality(fir and Siberian pine) in lowland was caused by the synergy of water stress(inciting factor) and barkbeetle attacks(contributing factor). Tree growth increment(GI) dynamics differs with respect to elevation. At high elevation(1700 m) GI permanently increased since warming onset, whereas at the middle(900 m) and low elevations(450 m) GI increased until c. 1983 yr. with followed depression. That GI 'breakpoint' occurred about a decade before hiatus onset. In spite of growth depression, during hiatus GI was higher than that in pre-warming period. At high elevation, GI positively responded to elevated June temperatures and negatively to moisture increase(precipitation, root zone moisture content, VPD, and SPEI). At low elevation GI negatively responded to June temperatures and positively to moisture increase. For both, low and high elevation, these patterns persisted throughout the study period(1967–2014). On the contrary, at middle elevations GI dependence on climate variables switch after breakpoint year(1983). Before breakpoint, June air temperature(positive correlation) and moisture(negative correlations) controlled GI. Further temperature increase leads GI depression and switched correlation signs to opposite(from positive to negative with temperature, and from negative to positive with moisture variables). | Viacheslav I.KHARUK Sergei T.IM Il'ya A.PETROV | 2018 | Journal of Mountain Science2018，15，12： | 1 |
| 17 | Preservation potential of individual couplet and deposition rates on mudflats in the Changjiang Estuary显示文摘Non-barrier mudflats in the Changjiang Estuary is examined to obtain preservation potentials and deposition rates over different time scales. The preservation potential of couplet is ca. 46.6% within daily scale and decreases as the time-interval extending, with 9.2% on a semi-lunar scale and 3.7% on a seasonal scale. In the long term, only 1.6% of daily deposition can potentially be preserved in the tidal flat sequence and other 98.4% have been eroded and leave sedimentary discordances, discernable or un-discernable, in the mudflat deposits. A negative log-linear relationship is examined between sedimentation rates and the time spans. The length of sedimentary hiatuses on the mudflat deposition were estimated with considerable uncertainty, but it can provide from an actualistic base some further insights into the nature and origin of ancient mudflat deposits with emphasis on the sedimentary discordances. | 范代读 李从先 陈美发 丁平兴 邓兵 杨守业 刘曙光 | 2001 | Science China Chemistry2001，44，S1： | 0 |
| 18 | A New Hiatus within the Lutetian of the El Basatin Section,Gebel Mokattam, Egypt:Field and Sedimentological Observations, with Special Emphasis on Nummulites显示文摘The Eocene succession of the El Basatin Section in Gebel Mokattam, east of Cairo, consists, from base to top, of two main units; the Mokattam and Maadi Formations. The Mokattam Formation consists of two Members, the Building Stone Member and the Giushi Member. The Upper Building Stone Member yielded six species of Nummulites belonging to the Upper Lutetian. These species are: Nummulites farisi Hussein et al., 2004; Nummulites cf. praegizehensis Boukhary and Hussein-Kamel, 1993; Nummulites cf. gizehensis(Forsk?l, 1775); Nummulites discorbinus(Schlotheim 1820) and Arxina schwageri(Silvestri, 1928) emended by Boukhary et al. 2012 and Nummulites crassichordatus Boukhary et al., 2010. The Giushi Member yielded three species that indicate a Bartonian age. These species, which continued from their first appearance in the Upper Building Stone Members, are N. discorbinus, A. schwageri and N. crassichordatus. The Maadi Formation, which has been previously considered to be of Bartonian–Priabonian age, is devoid of fossils in the study section. The two members of the Mokattam Formation represent a carbonate platform facies. The deposition of the Upper Building Stone Member was disturbed during the Lutetian by slumping and a convolute-bedding interval, indicating a short hiatus. The subsequent regression resulted in a very shallow marine to near-shore facies in the above Maadi Formation. | SAFIA Menoufy Al RADWAN Abul-Nasr MARWA Askar | 2019 | Acta Geologica Sinica(English Edition)2019，93，1： | 0 |
| 19 | False esophageal hiatus hernia caused by a foreign body: A fatal event显示文摘Foreign body ingestion is a common complaint in gastrointestinal clinics. It is usually not difficult to diagnose because most of the patients report a definitive history of accidental foreign body ingestion. However, in rare cases, patients do not have a clear history. Thus, the actual condition of the patient is difficult to diagnosis or is misdiagnosed; consequently, treatment is delayed or the wrong treatment is administered, respectively. This report describes a fatal case of esophageal perforation caused by an unknowingly ingested fishbone, which resulted in lower esophageal necrosis, chest cavity infection, posterior mediastinum fester, and significant upper gastrointestinal accumulation of blood. However, his clinical symptoms and imaging data are very similar with esophageal hiatal hernia. Unfortunately, because the patient was too late in consulting a physician, he finally died of chest infection and hemorrhage caused by thoracic aortic rupture. First, this case report underlines the importance of immediate consultation with a physician as soon as symptoms are experienced so as not to delay diagnosis and treatment, and thus avoid a fatal outcome. Second, diagnostic imaging should be performed in the early stage, without interference by clinical judgment. Third, when computed tomography reveals esophageal hiatus hernia with stomach incarceration, posterior mediastinal hematoma, and pneumatosis caused by esophageal, a foreign body should be suspected. Finally, medical professionals are responsible for making people aware of the danger of foreign body ingestion, especially among children, those who abuse alcohol, and those who wear dentures, particularly among the elderly, whose discriminability of foreign bodies is decreased, to avoid dire consequences. | Ya-Ping Lu Ming Yao Xu-Yan Zhou Bing Huang Wei-Bo Qi Zhi-Heng Chen Long-Sheng Xu | 2014 | World Journal of Gastroenterology2014，20，39： | 0 |
