| 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 | 上海26万妇女乳房自我检查随机试验显示文摘目的论证指导妇女进行乳房自我检查(BSE)是否能有效降低乳腺癌患者的死亡率。方法自1989年10月起,上海26.6万名年龄在30~64岁的妇女,随机进入指导组(132979名)和对照组(133085名)。在指导组,最初先由医务人员做规范的BSE手法演示,随后的4年中,使用BSE录像带进行二次强化教育,并定期进行BSE指导和在医务人员监察下进行BSE操作。本研究进行5年,全部活动均被记录。队列人群随访到2000年7月,乳腺癌患者的生存状况随访到2001年12月。统计分析采用Kaplan-Meier方法、Logrank检验以及Cox模型。结果指导组检出乳腺癌864例,其中死于乳腺癌133例;对照组检出乳腺癌896例,其中死于乳腺癌130例。两组乳腺癌病例的肿块大小、TNM分期和累积死亡率的差异均无统计学意义(P均>0.05)。但是指导组比对照组有较多和较小的纤维腺瘤被检出(P<0.01)。结论对人群开展BSE教育和指导,未能降低人群的乳腺癌死亡率;接受BSE教育的妇女比没有接受教育的妇女可检出较多的和较小的良性乳房肿块。 | 高道利 David BThomas Roberta M Ray 王文婉 Charlene J Allison 陈范良 Peggy Porter 胡永伟 赵关林 潘雷达 李雯瑾 武春园 Zakia Coriaty Ilonka Evans 林明纲 Helge Stalsberg Steven Gself | 2005 | 中华肿瘤杂志2005，27，6： | 14 |
| 3 | WJD 5^(th) Anniversary Special Issues(2): Type 2 diabetes Effects of exercise training on mitochondrial function in patients with type 2 diabetes显示文摘Type 2 diabetes is characterized by a decreased ability of insulin to facilitate glucose uptake into insulin sensitive tissue,i.e.,skeletal muscle.The mechanism behind this is at the moment unresolved.It has been suggested that increased amount of lipids inside the skeletal muscle(intramuscular triglyceride,diacylglycerol and ceramides)will impair insulin action in skeletal muscle,but data are not consistent in the human literature.It has also been hypothesized that the impaired insulin sensitivity is due to a dysfunction in the mitochondria resulting in an impaired ability to oxidize lipids,but the majority of the literature is not supporting this hypothesis.Recently it has been suggested that the production of reactive oxygen species play an essential role in skeletal muscle insulin sensitivity.It is well accepted that physical activity(endurance,strength and high intensity training)improves insulin sensitivity in healthy humans and in patients with type 2 diabetes.Whether patients with type 2 diabetes have the same beneficial effects(same improvement)as control subjects,when it comes to regular physical activity in regard to mitochondrial function,is not established in the literature.This review will focus only on the effect of physical activity on skeletal muscle(mitochondrial function)in patients with type 2 diabetes. | Steen Larsen Stinna Skaaby J rn W Helge Flemming Dela | 2014 | World Journal of Diabetes2014，5，4： | 2 |
