| 1 | On the combined effect of soil fertility and topography on tree growth in subtropical forest ecosystems—a study from SE China显示文摘Aims The aim of our research was to understand small-scale effects of topography and soil fertility on tree growth in a forest biodiversity and ecosystem functioning(BEF)experiment in subtropical SE China.Methods Geomorphometric terrain analyses were carried out at a spatial resolution of 5×5 m.Soil samples of different depth increments and data on tree height were collected from a total of 566 plots(667 m2 each).The soils were analyzed for carbon(soil organic carbon[SOC]),nitrogen,acidity,cation exchange capacity(CEC),exchangeable cations and base saturation as soil fertility attributes.All plots were classified into geomorphological units.Analyses of variance and linear regressions were applied to all terrain,soil fertility and tree growth attributes.Important Findings In general,young and shallow soils and relatively small differences in stable soil properties suggest that soil erosion has truncated the soils to a large extent over the whole area of the experiment.This explains the concurrently increasing CEC and SOC stocks downslope,in hollows and in valleys.However,colluvial,carbon-rich sediments are missing widely due to the convexity of the footslopes caused by uplift and removal of eroded sediments by adjacent waterways.The results showed that soil fertility is mainly influenced by topography.Monte-Carlo flow accumulation(MCCA),curvature,slope and aspect significantly affected soil fertility.Furthermore,soil fertility was affected by the different geomorphological positions on the experimental sites with ridge and spur positions showing lower exchangeable base cation contents,especially potassium(K),due to leaching.This geomorphological effect of soil fertility is most pronounced in the topsoil and decreases when considering the subsoil down to 50 cm depth.Few soil fertility attributes affect tree height after 1-2 years of growth,among which C stocks proved to be most important while pH_(KCl)and CEC only played minor roles.Nevertheless,soil acidity and a high proportion of Al on the exchange complex affected tree height even after only 1-2 years growth.Hence,our study showed that forest nutrition is coupled to a recycling of litter nutrients,and does not only depend on subsequent supply of nutrients from the mineral soil.Besides soil fertility,topography affected tree height.We found that especially MCCA as indicator of water availability affected tree growth at small-scale,as well as aspect.Overall,our synthesis on the interrelation between fertility,topography and tree growth in a subtropical forest ecosystem in SE China showed that topographic heterogeneity lead to ecological gradients across geomorphological positions.In this respect,small-scale soil-plant interactions in a young forest can serve as a driver for the future development of vegetation and biodiversity control on soil fertility.In addition,it shows that terrain attributes should be accounted for in ecological research. | Thomas Scholten Philipp Goebes Peter Kühn Steffen Seitz Thorsten Assmann Jürgen Bauhus Helge Bruelheide Francois Buscot Alexandra Erfmeier Markus Fischer Werner Härdtle Jin-Sheng He Keping Ma Pascal A.Niklaus Michael Scherer-Lorenzen Bernhard Schmid Xuezheng Shi Zhengshan Song Goddert von Oheimb Christian Wirth Tesfaye Wubet Karsten Schmidt | 2017 | Journal of Plant Ecology2017,10,1: | 22 |
| 2 | Simultaneous development of diabetic ketoacidosis and Hashitoxicosis in a patient treated with pegylated interferon-alpha for chronic hepatitis C显示文摘Classical interferon-alpha has been shown to be correlated with the development of a variety of autoimmune disorders. A 38 year-old female patient developed simultaneously diabetic ketoacidosis and hyperthyroidism 5 mo following initiation of treatment with pegylated interferon-α and ribavirin for chronic hepatitis C. High titers of glutamic acid decarboxylase, antinuclear and thyroid (thyroid peroxidase and thyroglobulin) antibodies were detected. Antiviral treatment was withdrawn and the patient was treated with insulin for insulin-dependent diabetes mellitus and propranolol for hyperthyroidism. Twelve months after cessation of pegylated interferon-α therapy the patient was euthyroid without any medication but remained insulin-dependent. | Aspasia S Soultati Spyridon P Dourakis Alexandra Alexopoulou Melanie Deutsch Athanasios J Archimandritis | 2007 | World Journal of Gastroenterology2007,13,8: | 15 |
| 3 | Restoration of energy level in the early phase of acute pediatric pancreatitis显示文摘Acute pancreatitis (AP) is a serious inflammatory disease with rising incidence both in the adult and pediatric populations. It has been shown that mitochondrial injury and energy depletion are the earliest intracellular events in the early phase of AP. Moreover, it has been revealed that restoration of intracellular ATP level restores cellular functions and defends the cells from death. We have recently shown in a systematic review and meta-analysis that early enteral feeding is beneficial in adults; however, no reviews are available concerning the effect of early enteral feeding in pediatric AP. In this minireview, our aim was to systematically analyse the literature on the treatmentof acute pediatric pancreatitis. The preferred reporting items for systematic review(PRISMA-P) were followed, and the question was drafted based on participants, intervention, comparison and outcomes: P: patients under the age of twenty-one suffering from acute pancreatitis; I: early enteral nutrition (per os and nasogastric- or nasojejunal tube started within 48 h); C: nil per os therapy; O: length of hospitalization, need for treatment at an intensive care unit, development of severe AP, lung injury (including lung oedema and pleural effusion), white blood cell count and pain score on admission. Altogether, 632 articles (Pub Med: 131; EMBASE: 501) were found. After detailed screening of eligible papers, five of them met inclusion criteria. Only retrospective clinical trials were available. Due to insufficient information from the authors, it was only possible to address length of hospitalization as an outcome of the study. Our mini-meta-analysis showed that early enteral nutrition significantly(SD = 0.806, P = 0.034) decreases length of hospitalization compared with nil per os diet in acute pediatric pancreatitis. In this minireview, we clearly show that early enteral nutrition, started within 24-48 h, is beneficial in acute pediatric pancreatitis. Prospective studies and better presentation of research are crucially needed to achieve a higher level of evidence. | Dóra Mosztbacher Nelli Farkas Margit Solymár Gabriella Pár Judit Bajor ákos Szucs József Czimmer Katalin Márta Alexandra Mikó Zoltán Rumbus Péter Varjú Péter Hegyi Andrea Párniczky | 2017 | World Journal of Gastroenterology2017,23,6: | 8 |
| 4 | 大气二氧化氮与每日总死亡率、心血管和呼吸系统疾病死亡率的短期关联:398个城市的多中心分析显示文摘目的:采用统一的分析方案,评估全球多个国家/地区的二氧化氮(NO_(2))与总死亡率、心血管和呼吸系统疾病死亡率之间的短期关联。研究设计:采用两阶段的时间序列分析方法、过度离散的广义线性模型和多水平meta分析。研究地点:22个低到高收入国家/地区的398个城市。主要结局指标:1973—2018年逐日总死亡人数(6280万人)、心血管疾病死亡人数(1970万人)和呼吸系统疾病死亡人数(550万人)。结果:平均而言,NO_(2)浓度在滞后1天(前1天)每增加10μg/m^(3),会导致总死亡率、心血管和呼吸系统疾病死亡率分别增加0.46%(95%可信区间0.36%~0.57%)、0.37%(0.22%~0.51%)、0.47%(0.21%~0.72%)。在对共污染物(PM_(10)、PM_(2.5)、臭氧、二氧化硫和一氧化碳)进行调整后,这些关联仍然很稳定。所有3种死因的暴露-反应曲线几乎是线性的,没有明显的阈值。在398个城市中,可归因于高过假定零水平的NO_(2)浓度造成的死亡比例为1.23%(95%可信区间0.96%~1.51%)。结论:这项多中心研究提供了关于NO_(2)短期暴露与总死亡率、心血管和呼吸系统死亡风险之间的独立和线性关联的关键证据,说明通过加强NO_(2)的控制和监管限制标准,可获得人群水平的健康收益。 | 孟夏 刘聪(校) 陈仁杰 郑湃(译) 阚海东(校) Francesco Sera Ana Vicedo-Cabrera Ai Milojevic Maria Guo Yuming Tong Shilu Micheline de Sousa Zanotti Stagliorio Coelh Paulo Hilario Nascimento Saldiva Eric Lavigne Patricia Matus Correa Nicolas Valdes Ortega Samuel Osorio Garcia Jan Kysely Ales Urban Hans Orru Marek Maasikmets Jouni J K Jaakkola Niilo Ryti Veronika Huber Alexandra Schneider Klea Katsouyanni Antonis Analitis Masahiro Hashizume Yasushi Honda Chris Fook Sheng Ng Baltazar Nunes João Paulo Teixeira Iulian Horia Holobaca Simona Fratianni Ho Kim Aurelio Tobias Carmeníniguez Bertil Forsberg ChristoferÅström Martina S Ragettli Yue-Liang Leon Guo Shih-Chun Pan Shanshan Li Michelle L Bell Antonella Zanobetti Joel Schwartz Tangchun Wu Antonio Gasparrini | 2021 | 英国医学杂志中文版2021,24,8: | 7 |
| 5 | Cholangiocarcinoma:A 7-year experience at a single center in Greece显示文摘AIM: To evaluate survival rate and clinical outcome of cholangiocarcinoma.METHODS: The medical records of 34 patients with cholangiocarcinoma,seen at a single hospital between the years 1999-2006,were retrospectively reviewed.RESULTS: Thirty-four patients with a median age of 75 years were included.Seventeen (50%) had painless jaundice at presentation.Sixteen (47.1%) were perihilar,15 (44.1%) extrahepatic and three (8.8%) intrahepatic.Endoscopic retrograde cholangiography (ERCP) and/or magnetic resonance cholangiography (MRCP) were used for the diagnosis.Pathologic confirmation was obtained in seven and positive cytological examination in three.Thirteen patients had co-morbidities (38.2%).Four cases were managed with complete surgical resection.All the rest of the cases (30) were characterized as non-resectable due to advanced stage of the disease.Palliative biliary drainage was performed in 26/30 (86.6%).The mean follow-up was 32 mo (95% CI,20-43 mo).Overall median survival was 8.7 mo (95% CI,2-16 mo).The probability of 1-year,2-year and 3-year survival was 46%,20% and 7%,respectively.The survival was slightly longer in patients who underwent resection compared to those who did not,but this difference failed to reach statistical significance.Patients who underwent biliary drainage had an advantage in survival compared to those who did not (probability of survival 53% vs 0% at 1 year,respectively,P = 0.038).CONCLUSION: Patients with cholangiocarcinoma were usually elderly with co-morbidities and/or advanced disease at presentation.Even though a slight amelioration in survival with palliative biliary drainage was observed,patients had dismal outcome without resection of the tumor. | Alexandra Alexopoulou Aspasia Soultati Spyros P Dourakis Larissa Vasilieva Athanasios J Archimandritis | 2008 | World Journal of Gastroenterology2008,14,40: | 3 |

| 7 | Association between tea consumption and cognitive function in cognitively healthy older adults and older adults with mild cognitive impairment显示文摘Background Prospective studies suggest that tea consumption may decrease the risk for cognitive impairment in late life.However,little research has examined the association between tea consumption and cognitive performance across multiple domains.In addition,no research has examined the benefit of tea consumption on cognitive performance among older adults with existing impairment.Aims The current study examined the association between tea consumption and performance on tasks of global cognitive function,episodic memory and executive function in cognitively healthy(CH)older adults and older adults with mild cognitive impairment(MCI).Methods The analytical sample included 1849 community-dwelling older adults from the Shanghai Brain Aging Study(65.6%female,mean age of 69.50(8.02)years).Following ascertainment of cognitive function,816 were categorised as MCI.In addition to completion of a demographics questionnaire,participants reported their tea consumption and completed a battery of tests to measure global cognitive function,episodic memory and working memory.Results Independent analyses of covariance revealed a significant association between tea consumption and measures of episodic memory;however,these associations were restricted to CH older adults but not older adults with MCI.Tea consumption was not associated with working memory performance.Conclusions The current study suggests that the benefit of tea consumption is restricted to cognitively healthy older adults and does not extend to older adults with MCI. | Hua Xu Alexandra J Fiocco Xiaohua Liu Tao Wang Guanjun Li Shifu Xiao the research group of Shanghai Brain Aging Study | 2021 | General Psychiatry2021,34,4: | 2 |
| 8 | Abnormal liver chemistries as a predictor of COVID-19 severity and clinical outcomes in hospitalized patients显示文摘BACKGROUND Abnormal liver chemistries are common findings in patients with Coronavirus Disease 2019(COVID-19).However,the association of these abnormalities with the severity of COVID-19 and clinical outcomes is poorly understood AIM We aimed to assess the prevalence of elevated liver chemistries in hospitalized patients with COVID-19 and compare the serum liver chemistries to predict the severity and in-hospital mortality.METHODS This retrospective,observational study included 3380 patients with COVID-19 who were hospitalized in the Johns Hopkins Health System(Baltimore,MD,United States).Demographic data,clinical characteristics,laboratory findings,treatment measures,and outcome data were collected.Cox regression modeling was used to explore variables associated with abnormal liver chemistries on admission with disease severity and prognosis RESULTS A total of 2698(70.4%)had abnormal alanine aminotransferase(ALT)at the time of admission.Other more prevalent abnormal liver chemistries were aspartate aminotransferase(AST)(44.4%),alkaline phosphatase(ALP)(16.1%),and total bilirubin(T-Bil)(5.9%).Factors associated with liver injury were older age,Asian ethnicity,other race,being overweight,and obesity.Higher ALT,AST,T-Bil,and ALP levels were more commonly associated with disease severity.Multivariable adjusted Cox regression analysis revealed that abnormal AST and T-Bil were associated with the highest mortality risk than other liver injury indicators during hospitalization.Abnormal AST,T-Bil,and ALP were associated with a need for vasopressor drugs,whereas higher levels of AST,T-Bil,and a decreased albumin levels were associated with mechanical ventilation CONCLUSION Abnormal liver chemistries are common at the time of hospital admission in COVID-19 patients and can be closely related to the patient’s severity and prognosis.Elevated liver chemistries,specifically ALT,AST,ALP,and T-Bil levels,can be used to stratify risk and predict the need for advanced therapies in these patients. | Arunkumar Krishnan Laura Prichett Xueting Tao Saleh A Alqahtani James P Hamilton Esteban Mezey Alexandra T Strauss Ahyoung Kim James J Potter Po-Hung Chen Tinsay A Woreta | 2022 | World Journal of Gastroenterology2022,28,5: | 2 |
