| 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 |

| 3 | How to perform gastrointestinal ultrasound: anatomy and normal findings显示文摘Gastrointestinal ultrasound is a practical, safe, cheap and reproducible diagnostic tool in inflammatorybowel disease gaining global prominence amongst clinicians. Understanding the embryological processes of the intestinal tract assists in the interpretation of abnormal sonographic findings. In general terms, the examination principally comprises interrogation of the colon, mesentery and small intestine using both lowfrequency and high-frequency probes. Interpretation of findings on GIUS includes assessment of bowel wall thickness, symmetry of this thickness, evidence of transmural changes, assessment of vascularity using Doppler imaging and assessment of other specific features including lymph nodes, mesentery and luminal motility. In addition to B-mode imaging, transperineal ultrasonography, elastography and contrast-enhanced ultrasonography are useful adjuncts. This supplement expands upon these features in more depth. | Nathan S S Atkinson Robert V Bryant Yi Dong Christian Maaser Torsten Kucharzik Giovanni Maconi Anil K Asthana Michael Blaivas Adrian Goudie Odd Helge Gilja Dieter Nuernberg Dagmar Schreiber-Dietrich Christoph F Dietrich | 2017 | World Journal of Gastroenterology2017，23，38： | 5 |

| 5 | Overweight and obesity in hip and knee arthroplasty:Evaluation of 6078 cases显示文摘AIM: To evaluate a possible association between thevarious levels of obesity and peri-operative characteristics of the procedure in patients who underwent endoprosthetic joint replacement in hip and knee joints. METHODS: We hypothesized that obese patients were treated for later stage of osteoarthritis, that more conservative implants were used, and the intraand perioperative complications increased for such patients. We evaluated all patients with body mass index(BMI) ≥ 25 who were treated in our institution from January 2011 to September 2013 for a primary total hip arthroplasty(THA) or total knee arthroplasty(TKA). Patients were split up by the levels of obesity according to the classification of the World Health Organization. Average age at the time of primary arthroplasty, preoperative Harris Hip Score(HHS), Hospital for Special Surgery score(HSS), gender, type of implanted prosthesis, and intra-and postoperative complications were evaluated.RESULTS: Six thousand and seventy-eight patients with a BMI ≥ 25 were treated with a primary THA or TKA. Age decreased significantly(P < 0.001) by increasing obesity in both the THA and TKA. HHS and HSS were at significantly lower levels at the time of treatment in the super-obese population(P < 0.001). Distribution patterns of the type of endoprostheses used changed with an increasing BMI. Peri- and postoperative complications were similar in form and quantity to those of the normal population. CONCLUSION: Higher BMI leads to endoprosthetic treatment in younger age, which is carried out at significantly lower levels of preoperative joint function. | Daniel Guenther Stefan Schmidl Till O Klatte Harald K Widhalm Mohamed Omar Christian Krettek Thorsten Gehrke Daniel Kendoff Carl Haasper | 2015 | World Journal of Orthopedics2015，6，1： | 4 |
| 6 | Keratinocytes costimulate naive human T cells via CD2: a potential target to prevent the development of proinflammatory Th1 cells in the skin显示文摘The interplay between keratinocytes and immune cells,especially T cells,plays an important role in the pathogenesis of chronic inflammatory skin diseases.During psoriasis,keratinocytes attract T cells by releasing chemokines,while skin-infiltrating selfreactive T cells secrete proinflammatory cytokines,e.g.,IFN γand IL-17A,that cause epidermal hyperplasia.Similarly,in chronic graftversus-host disease,allogenic IFN γ-producing Th1/Tc1 and IL-17-producing Th17/Tc17 cells are recruited by keratinocyte-derived chemokines and accumulate in the skin.However,whether keratinocytes act as nonprofessional antigen-presenting cells to directly activate naive human T cells in the epidermis remains unknown.Here,we demonstrate that under proinflammatory conditions,primary human keratinocytes indeed activate naive human T cells.This activation required cell contact and costimulatory signaling via CD58/CD2 and CD54/LFA-1.Naive T cells costimulated by keratinocytes selectively differentiated into Th1 and Th17 cells.In particular,keratinocyte-initiated Th1 differentiation was dependent on costimulation through CD58/CD2.The latter molecule initiated STAT1 signaling and IFN γproduction in T cells.Costimulation of T cells by keratinocytes resulting in Th1 and Th17 differentiation represents a new explanation for the local enrichment of Th1 and Th17 cells in the skin of patients with a chronic inflammatory skin disease.Consequently,local interference with T cell–keratinocyte interactions may represent a novel strategy for the treatment of Th1 and Th17 cell-driven skin diseases. | Christian Orlik Daniel Deibel Johanna Küblbeck Emre Balta Sabina Ganskih Jüri Habicht Beate Niesler Jutta Schröder-Braunstein Knut Schäkel Guido Wabnitz Yvonne Samstag | 2020 | Cellular & Molecular Immunology2020，17，4： | 4 |
| 7 | Modulating effects of acyl-CoA synthetase 5-derived mitochondrial Wnt2B palmitoylation on intestinal Wnt activity显示文摘AIM:To investigate the role of acyl-CoA synthetase 5(ACSL5)activity in Wnt signaling in intestinal surface epithelia.METHODS:Several cell lines were used to investigate the ACSL5-dependent expression and synthesis of Wnt2B,a mitochondrially expressed protein of the Wnt signaling family.Wnt activity was functionally assessed with a luciferase reporter assay.ACSL5-related biochemical Wnt2B modifications were investigatedwith a modified acyl-exchange assay.The findings from the cell culture models were verified using an Apcmin/+mouse model as well as normal and neoplastic diseased human intestinal tissues.RESULTS:In the presence of ACSL5,Wnt2B was unable to translocate into the nucleus and was enriched in mitochondria,which was paralleled by a significant decrease in Wnt activity.ACSL5-dependent S-palmitoylation of Wnt2B was identified as a molecular reason for mitochondrial Wnt2B accumulation.In cell culture systems,a strong relation of ACSL5 expression,Wnt2B palmitoylation,and degree of malignancy were found.Using normal mucosa,the association of ACSL5 and Wnt2B was seen,but in intestinal neoplasias the mechanism was only rudimentarily observed.CONCLUSION:ACSL5 mediates antiproliferative activities via Wnt2B palmitoylation with diminished Wnt activity.The molecular pathway is probably relevant for intestinal homeostasis,overwhelmed by other pathways in carcinogenesis. | Christina Klaus Ursula Schneider Christian Hedberg Anke K Schütz Jürgen Bernhagen Herbert Waldmann Nikolaus Gassler Elke Kaemmerer | 2014 | World Journal of Gastroenterology2014，20，40： | 4 |
| 8 | Rodent epididymal cDNAs identified by sequence homology to human and canine counterparts显示文摘Aim: Identification of the rodent counterparts of human and canine epididymal cDNAs HE3, HE4 and CeS/Ly6G5C by sequence homology and analysis of their expression patterns and regulation level in the rat. Methods:'Electronic screening' of Expressed Sequence Tag (EST) and genomic databases, followed by RT-PCR and Northern blot analysis. Results: Rodent ESTs and genomic sequences homologous to HE3, HE4 and CeS/Ly6G5C were identified in the public databases and the 'full-length' rat cDNAs cloned. To emphasise their homology to the human and canine genes, they were named Me3/Re3, Me4/Re4 and Re8 for mouse and rat counterparts, respectively, mRNA expression patterns were analysed in rats, including rat HE1 and HE5/CD52 counterparts as controls. Re3 and Re8 mRNAs were only found in the rat epididymis, while Re4 showed a broader tissue distribution. Within the epididymis,Re3 and Re4 mRNAs were detected in all regions; ReS, on the other hand, was restricted to the caput. During postnatal development, Re3 and control mRNAs were found from the earliest stages investigated, while Re8 mRNA was observed only from day 24 postnatum, corresponding to the onset of spermatogenesis in the prepubertal testis.Castration and testosterone supplementation of adult male rats suggested that none of the cloned mRNAs was directly androgen-regulated. Efferent duct ligation, however, showed that Re8 mRNA levels depended on testicular factors other than androgens. Conclusion: The novel rodent cDNAs can now be used to monitor epididymal gene expression more closely and to set up various regulatory and functional studies. | Katrin Kppler-Hanno Christiane Kirchhoff | 2003 | Asian Journal of Andrology2003，5，4： | 4 |
| 9 | 【特刊综述】性腺功能低下在克氏综合征中的角色显示文摘克氏综合症(47,XXY)(KS)是最常见的性染色体异常,也是男性不育和性腺功能低下的常见原因。大部分KS患者终其一生都不知道自己患有这个疾病,只有25%的患者得到诊断,而在青春期前被诊断的更是少数。除了性腺功能低下和无精子症,大多数KS患者都有一定程度的学习障碍,并且可能有多种精神问题。长期性腺功能低下的影响可能使其难以与额外的x染色体引起的基因剂量效应相辨别。不管是什么原因,KS患者常出现身体成分的改变,包括脂肪增加、肌肉减少和骨矿物质流失,同时发生代谢障碍的风险也增加,例如患2型糖尿病和代谢综合征。这些发现应该引起我们的重视,因为他们不仅仅是简单的化验结果,流行病学调查表明KS患者因不同的疾病住院和死亡的风险均增加。KS患者应该在青春期早期就被给予睾丸激素治疗,尽管目前证据不足,因为至今仍未有随机对照试验的文章发表过。在这篇文章里,我们回顾了近期关于KS患者性腺功能低下症的研究进展和睾丸激素治疗的合理性,希望能为这个常见但往往被忽视的综合征提出我们的最佳建议。 | Christian Host Anne Skakkeb k Kristian A Groth Anders Bojesen | 2014 | Asian Journal of Andrology2014，16，2： | 3 |

| 11 | Estimation of Throughfall Erosivity in a Highly Diverse Forest Ecosystem Using Sand-Filled Splash Cups显示文摘Sand-filled splash cups were used to study the erosive power of rainfall and throughfall in the humid subtropics of Southeast China. The splash cup measurements yielded precise and reproducible results under both open field conditions and forest vegetation. The splash cups were exposed to specific forest stands of different ages and to selected species (Schima superba, Castanopsis eyrei, Daphniphyllum oldhamii, Lithocarpus glaber) in the Gutianshan (古田山) National Nature Reserve (GNNR). The results of the measurements under forest vegetation show that the erosive power of throughfall drops to be 2.59 times higher compared to the open field. This accentuates the importance of shrub, herb and litter layers in forest ecosystems to protect the soil against erosion. Coalescing drops from leaves and branches (drips) are responsible for this notable gain in erosive power. Moreover, differences in sandloss between the investigated tree species (deciduous, evergreen) revealed that the erosion potential and the spatial heterogeneity of throughfall are species-specific. This highlights the importance of selecting specific species for afforestation projects considering the prevention of soil erosion. | Christian Geiβler Peter Kühn 史学正 Thomas Scholten | 2010 | Journal of Earth Science2010，21，6： | 2 |
