| 1 | 黄土高原中部450ka以来植被演化的有机碳同位素与分子化石记录显示文摘黄土高原地质历史时期不同时间尺度上的植被演化规律与气候环境影响因素,以及植被替代性指标的解译等问题还值得进一步研究.本工作拟通过对灵台黄土剖面450ka以来黄土-古土壤样品总有机碳同位素(δ^(13)CTOC)和正构烷烃含量组合参数如C31/C27进行综合对比研究,从而为明晰这些问题提供一些新的讨论和证据.结果表明,450ka以来黄土高原中部C_3、C_4植物混生,以C_3植物为主;按生活型则草本、木本混生,以草本植物为主.在黄土高原气候较温暖湿润的MIS9(S3时期),MIS5(S1时期)阶段,可能出现过C_3木本植物的短暂增多,但总体上不存在大面积的森林.在阶段性变化上,黄土高原130ka以来草本植物总体增多,可能与区域性气候干旱化有关.在轨道尺度上,全新世较末次冰期,MIS11(S4时期)较MIS12(L5时期)C_3草本植物减少;在其他几个冰期旋回,间冰期较相应冰期C_3草本植物增多.植被替代性指标与建群种蒿属孢粉量的变化吻合较好,其变化可能与冰期旋回上水热配置有关.MIS1(S0时期)与MIS11(S4时期)气候相似,但全新世时期松属乔木的大量增多,暗示了人类活动和生态因子火活动的影响. | 周斌 古再丽努尔·外力 France PETERSE Michael I BIRD | 2016 | 中国科学:地球科学2016，46，4： | 11 |
| 2 | Natural history of hepatic metastases from colorectal cancer-pathobiological pathways with clinical significance显示文摘Colorectal cancer hepatic metastases represent the final stage of a multi-step biological process.This process starts with a series of mutations in colonic epithelial cells,continues with their detachment from the large intestine,dissemination through the blood and/or lymphatic circulation,attachment to the hepatic sinusoids and interactions with the sinusoidal cells,such as sinusoidal endothelial cells,Kupffer cells,stellate cells and pit cells.The metastatic sequence terminates with colorectal cancer cell invasion,adaptation and colonisation of the hepatic parenchyma.All these events,termed the colorectal cancer invasion-metastasis cascade,include multiple molecular pathways,intercellular interactions and expression of a plethora of chemokines and growth factors,and adhesion molecules,such as the selectins,the integrins or the cadherins,as well as enzymes including matrix metalloproteinases.This review aims to present recent advances that provide insights into these cell-biological events and emphasizes those that may be amenable to therapeutic targeting. | Konstantinos A Paschos Ali W Majeed Nigel C Bird | 2014 | World Journal of Gastroenterology2014，20，14： | 10 |
| 3 | On the mechanical behavior of the human biliary system显示文摘This paper reviews the progress made in understanding the mechanical behaviour of the biliary system. Gallstones and diseases of the biliary tract affect more than 10% of the adult population. The complications of gallstones, i.e. acute pancreatitis and obstructive jandice, can be lethal, and patients with acalculous gallbladder pain often pose diagnostic difficulties and undergo repeated ultrasound scans and oral cholecystograms. Moreover, surgery to remove the gallbladder in these patients, in an attempt to relieve the symptoms, gives variable results. Extensive research has been carried out to understand the physiological and pathological functions of the biliary system, but the mechanism of the pathogenesis of gallstones and pain production still remain poorly understood. It is believed that the mechanical factors play an essential role in the mechanisms of the gallstone formation and biliary diseases. However, despite the extensive literature in clinical studies, only limited work has been carried out to study the biliary system from the mechanical point of view. In this paper, we discuss the state of art knowledge of the fluid dynamics of bile flow in the biliary tract, the solid mechanics of the gallbladder and bile ducts, recent mathematical and numerical modelling of the system, and finally the future challenges in the area. | Xiaoyu Luo Wenguang Li Nigel Bird Swee Boon Chin NA Hill Alan G Johnson | 2007 | World Journal of Gastroenterology2007，13，9： | 9 |
| 4 | Organic carbon isotope and molecular fossil records of vegetation evolution in central Loess Plateau since 450 kyr显示文摘Significant uncertainties remain regarding the temporal evolution of natural vegetation during the Quaternary, and drivers of past vegetation change, on the Chinese Loess Plateau(CLP). This study presents analyses of total organic carbon isotopic composition(TOC) and n-alkane ratios(C31/C27) from the Lingtai loess-palaeosol sequence on the central CLP over the last 450 kyr. The results demonstrate that the vegetation in this region comprised a mix of C_3 and C_4 plants of herb and woody growth-form. C_3 plants dominated for most of the last 450 kyr, but this did not lead to extensive forest. C_3 woody plants were more abundant in MIS9(S3 period) and MIS5(S1 period) during warm and humid climate conditions. Herbs increased in the region since 130 kyr, possibly as a result of increased aridity. On the orbital timescales, there was a reduction of C_3 herbal plants in MIS11(S4) than in MIS12(L5), and in Holocene than in the last glacial period. Our isotope and n-alkane proxy records are in agreement with Artemisia pollen changes in the region, which is/was the dominant species in this area and varying due to different heat and water conditions between glacial and interglacial periods. Though the climate in MIS1(S0) was similar to that in MIS11(S4), a significant increase in woody plants during the Holocene suggests the impact of human activities and ecological effects of changes in fire activity. | ZHOU Bin WALI Guzalnur Francien PETERSE Michael I BIRD | 2016 | Science China Earth Sciences2016，59，6： | 7 |
| 5 | Resistin mediates the hepatic stellate cell phenotype显示文摘AIM: To describe the role of resistin in liver fibrosis. METHODS: For the in vivo animal study, Sprague Dawley rats were subjected to bile duct ligation (BDL) for 4 wk. Rat liver, adipose tissue (epididymal fat) and serum were analyzed for resistin expression. For the in vitro experiment, rat primary hepatic stellate cells (HSCs) and Kupffer cells (KCs) were used. HSCs were exposed to recombinant resistin, and collagenⅠ, transforming growth factor β1, α smooth muscle actin, tissue inhibitor of metalloproteinase 1 and connective tissue growth factor expression were analyzed. Resistin gene and protein expression was quantified as was the expression of pro-inflammatory cytokines including tumor necrosis factor α (TNFα), interleukin (IL)-1, IL-6, IL-8 and monocyte chemotactic protein-1 (MCP-1). The effects of resistin on HSC proliferation, migration and apoptosis were determined. The effects of resistin on KCs were also investigated. RESULTS: Following BDL, rat epididymal fat and serum rather than liver showed higher resistin expression compared to control rats. In liver, resistin was expressed in quiescent HSCs and KCs. Resistin treatment resulted in enhancement of TNFα , IL-6 , IL-8 and MCP-1 gene expression and increased IL-6 and MCP-1 protein in HSCs. Resistin activated HSC phospho-MAPK/p38, and p38 inhibition diminished IL-6 and MCP-1 expression. Furthermore, resistin facilitated HSC proliferation and migration, but decreased apoptosis which was via an IL-6 and MCP-1 mechanism. Finally, resistin-induced transforming growth factor β1 from KCs enhanced HSC collagenⅠexpression. CONCLUSION: Resistin directly and indirectly modulates HSC behavior towards a more pro-fibrogenic phenotype. | Zhi-Xia Dong Lin Su Joanne Brymora Claire Bird Qing Xie Jacob George Jian-Hua Wang | 2013 | World Journal of Gastroenterology2013，19，28： | 4 |
| 6 | Uncommon presentation of a common disease-Bouveret's syndrome:A case report and systematic literature review显示文摘AIM To investigate and summarise the current evidence surrounding management of Bouveret's syndrome(BS).METHODS A MEDLINE search was performed for the BS. The search was conducted independently by two clinicians(Yahya ALHabbal and Matthew Ng) in April 2016. A case of BS is also described.RESULTS A total of 315 articles, published from 1967 to 2016, were found. For a clinically meaningful clinical review, articles published before 01/01/1990 and were excluded, leaving 235 unique articles to review. Twenty-seven articles were not available(neither by direct communication nor through inter-library transfer). These were also excluded. The final number of articles reviewed was 208. There were 161 case reports, 13 reviews, 23 images(radiological and clinical images), and 11 letters to editor. Female to male ratio was 1.82. Mean age was 74 years. Treatment modalities included laparotomy in the majority of cases, laparoscopic surgery, endoscopic surgery and shockwave lithotripsy.CONCLUSION There is limited evidence in the literature about the appropriate approach. We suggest an algorithm for management of BS. | Yahya AL-Habbal Matthew Ng David Bird Trevor McQuillan Haytham AL-Khaffaf | 2017 | World Journal of Gastrointestinal Surgery2017，9，1： | 4 |
