5贵州锦丰(烂泥沟)超大型金矿床构造解析及构造成矿作用显示文摘在矿区大比例尺填图的基础上,运用构造解析的理论和方法,对贵州锦丰(烂泥沟)金矿的构造特征、构造演化和构造控矿作用进行了系统的阐述。矿区构造线主要分为近NS向、NW向和NE向3组,其中NW向构造线控制了矿区的构造格架。构造变形主要经历了同生期裂陷、造山期挤压、后碰撞造山侧向挤压和岩石圈伸展等4个阶段。盆地裂陷期间(D2-T2)形成的同生断层为后续的构造活动提供了最初的构造薄弱面,并成为主要的热液通道;造山期挤压期间(T3)形成了矿区最为明显的近NS向和NW向大型倒转褶皱和逆冲断层以及配套的NE向右旋走滑断层;后碰撞造山侧向挤压期间(J1)形成走向NE的叠加褶皱,并在F2-F3'X'型断裂系上形成近EW向的拉张区,矿质沿着拉张的空间沉淀就位;燕山期(J2-K)岩石圈伸展,形成小规模的近水平逆断层。上述4个主要构造变形阶段与右江盆地的裂陷-闭合-坍塌的发展演化历史相吻合,成矿发生在由挤压向拉张过渡的构造体制转换阶段。造山期逆冲作用形成的构造闭圈和后碰撞造山期间挤压向伸展转变的过程中形成的局部张性构造环境是矿质得以大量聚集、沉淀的主要构造控制因素。构造成矿作用是锦丰(烂泥沟)金矿单一矿体垂向延深1000m以上的主要制约因素。构造成矿的观点将为在滇黔桂'金三角'卡林型金矿带的深部找矿提供重要的理论依据。陈懋弘 毛景文 Phillip J.Uttley Tony Norman 吴六灵 郑建民 秦运忠 2007矿床地质2007,26,4:51
6香港华人妇女产后抑郁危险因素的前瞻性研究显示文摘目的:产后抑郁是一种常见的精神障碍,对产妇、新生儿和其它家庭成员导致广泛的伤害。产后抑郁的病因学研究大多是基于西方样本,对其中的社会文化原因也缺乏实证研究。本研究从人口学、心理社会及种族文化因素等方面探讨中国妇女产后抑郁症状学的决定因素。方法:在大学附属综合医院产前门诊连续收集登记的中国孕妇959例,从她们第一次产前检查开始评估(基线),以后分别在孕期的最后3个月、产后即刻和产后3个月时评估。调查涉及的危险因素分6个方面:人口学和社会经济背景,躯体疾病及精神疾病病史, 产前抑郁情绪,围生期应激源,人际关系,和种族文化环境。采用等级回归进行分析。因变量是产后3个月时的抑郁评分。结果:决定产后抑郁症状学的因素有:目前的生活事件,缺乏社会支持,婚姻不满意,既往有故意自伤史,以及产前存在抑郁情绪。婆媳关系不好和没有陪月在产后阶段也与抑郁评分高有关联。结论:西方研究所确立的产后抑郁危险因素大体适用于中国妇女。产褥期的社会文化特点同样对产妇情绪有影响。Dominic TS Lee Alexander SK Yip Sandra SM Chan Fiona FY Lee Tony YS Leung Tony KH Chung 2005中国心理卫生杂志2005,19,9:50
7Pyogenic liver abscess:An audit of 10 years’experience显示文摘AIM:To describe our own experience with pyogenic liver abscesses over the past 10 years and investigate the risk factors associated with failure of initial percutaneous therapy.METHODS:A retrospective study of records of 63 PLA patients presenting between 1998 and 2008 to Australian tertiary referral centre,were reviewed.Amoebic and hydatid abscesses were excluded.Demographic,clinical,radiological,and microbiological characteristics,as well as surgical/radiological interventions,were recorded.RESULTS:Sixty-three patients(42 males,21 females) aged 65(±14) years[mean±(SD) ]had prodromal symptoms for a median(interquartile range;IQR) of 7(5-14) d.Only 59%of patients were febrile at presentation;however,the serum C-reactive protein was elevated in all 47 in whom it was measured.Liver function tests were non-specifically abnormal.67%of patients had a solitary abscess,while 32%had>3 abscesses with a median(IQR) diameter of 6.3(4-9) cm.Causative organisms were:Streptococcus milleri 25%,Klebsiella pneumoniae 21%,and Escherichia coli 16%.A presumptive cryptogenic cause was most common (34%).Four patients died in this series:one from sepsis,two from advanced cancer,and one from acute myocardial infarction.The initial procedure was radiological aspiration±drainage in 54 and surgery in two patients.17%underwent surgical management during their hospitalization.Serum hypoalbuminaemia[mean (95%CI) :32(29-35) g/L vs 28(25-31) g/L,P=0.045] on presentation was found to be the only factor related to failure of initial percutaneous therapy on univariate analysis.CONCLUSION:PLA is a diagnostic challenge,because the presentation of this condition is non-specific.Intravenous antibiotics and radiological drainage in the first instance allows resolution of most PLAs;However,a small proportion of patients still require surgical drainage.Tony CY Pang Thomas Fung Jaswinder Samra Thomas J Hugh Ross C Smith 2011World Journal of Gastroenterology2011,17,12:46
8Use of portal pressure studies in the management of variceal haemorrhage显示文摘Portal hypertension occurs as a complication of liver cirrhosis and complications such as variceal bleeding lead to significant demands on resources. Endoscopy is the gold standard method for screening cirrhotic patients however universal endoscopic screening may mean a lot of unnecessary procedures as the presence of oesophageal varices is variable hence a large time and cost burden on endoscopy units to carry out both screening and subsequent follow up of variceal bleeds. A less invasive method to identify those at high risk of bleeding would allow earlier prophylactic measures to be applied. Hepatic venous pressure gradient (HVPG) is an acceptable indirect measurement of portal hypertension and predictor of the complications of portal hypertension in adult cirrhotics. Varices develop at a HVPG of 10-12 mmHg with the appearance of other complications with HPVG > 12 mmHg. Variceal bleeding does not occur in pressures under 12 mmHg. HPVG > 20 mmHg measured early after admission is a significant prognostic indicator of failure to control bleeding varices, indeed early transjugular intrahepatic portosystemic shunt (TIPS) in such circumstances reduces mortality significantly. HVPG can be used to identify responders to medical therapy. Patients who do not achieve the suggested reduction targets in HVPG have a high risk of rebleeding despite endoscopic ligation and may not derive significant overall mortality benefit from endoscopic intervention alone, ultimately requiring TIPS or liver transplantation. Early HVPG measurements following a variceal bleed can help to identify those at risk of treatment failure who may benefit from early intervention with TIPS. Therefore, we suggest using HVPG measurement as the investigation of choice in those with confirmed cirrhosis in place of endoscopy for intitial variceal screening and, where indicated, a trial of B-blockade, either intravenously during the initial pressure study with assessment of response or oral therapy with repeat HVPG six weeks later. In those with elevated pressures, primary medical prophylaxis could be commenced with subsequent close monitoring of HVPG thus negating the need for endoscopy at this point. All patients presenting with variceal haemorrhage should undergo HVPG measurement and those with a gradient greater than 20 mmHg should be considered for early TIPS. By introducing portal pressure studies into a management algorithm for variceal bleeding, the number of endoscopies required for further intervention and follow up can be reduced leading to significant savings in terms of cost and demand on resources.Jennifer Addley Tony CK Tham William Jonathan Cash 2012World Journal of Gastrointestinal Endoscopy2012,4,7:37
9Exploitation of Fenton and Fenton-like reagents as alternative conditioners for alum sludge conditioning显示文摘The use of Fenton's reagent(Fe2+/H2O2) and Fenton-like reagents containing transition metals of Cu(II) ,Zn(II) ,Co(II) ,and Mn(II) for an alum sludge conditioning to improve its dewaterability was investigated. The results obtained were compared with those obtained from conditioning the same alum sludge using cationic and anionic polymers. Experimental results show that Fenton's reagent was the best among the Fenton and Fenton-like reagents for the alum sludge conditioning. A considerable effiectiveness of capillary suction time(CST) reduction efflciency of 47% can be achieved under test conditions of Fe2+/H2O2 = 20/125 mg/g DS(dry solid) and pH 6.0. The observation of floc-like particles after Fenton's reagent conditioning of alum sludge suggested that the mechanism of Fenton's reagent conditioning was different from that of polymer conditioning. In spite of the lower efflciency in the CST reduction of Fenton's reagent in alum sludge conditioning compared to that of polymer conditioning,Fenton's reagent o?ers a more environmentally safe option. This study provided an example of proactive treatment engineering,which is aimed at seeking a safe alternative to the use of polymers in sludge conditioning towards achieving a more sustainable sludge management strategy.Maha A.

11Update on hepatocellular carcinoma: Pathologists' review显示文摘Histopathologic diversity and several distinct histologic subtypes of hepatocellular carcinoma(HCC) are well-recognized. Recent advances in molecular pathology and growing knowledge about the biology associated with distinct histologic features and immuno-profile in HCC allowed pathologists to update classifications. Improving sub-classification will allow for more clinically relevant diagnoses and may allow for stratification into biologically meaningful subgroups. Therefore, immuno-histochemical and molecular testing are not only diagnostically useful, but also are being incorporated as crucial components in predicting prognosis of the patients with HCC. Possibilities of targeted therapy are being explored in HCC, and it will be important for pathologists to provide any data that may be valuable from a theranostic perspective. Herein, we review and provide updates regarding the pathologic sub-classification of HCC.Pathologic diagnostic approach and the role of biomarkers as prognosticators are reviewed. Further, the histopathology of four particular subtypes of HCC:Steatohepatitic, clear cell, fibrolamellar and scirrhous-and their clinical relevance, and the recent consensus on combined HCC-cholangiocarcinoma is summarized. Finally, emerging novel biomarkers and new approaches to HCC stratification are reviewed.Tony El Jabbour Stephen M Lagana Hwajeong Lee 2019World Journal of Gastroenterology2019,25,14:25
12Risk factors and outcome of bacterial infections in cirrhosis显示文摘Viable and non-viable pathological bacterial translocation promote a self-perpetuating circle of dysfunctional immune activation and systemic inflammation facilitating infections and organ failure in advanced cirrhosis.Bacterial infections and sepsis are now recognized as a distinct stage in the natural progression of chronic liver disease as they accelerate organ failure and contribute to the high mortality observed in decompensated cirrhosis.The increasing knowledge of structural,immunological and hemodynamic pathophysiology in advanced cirrhosis has not yet translated into significantly improved outcomes of bacterial infections over the last decades.Therefore,early identification of patients at the highest risk for developing infections and infectionrelated complications is required to tailor the currently available measures of surveillance,prophylaxis and therapy to the patients in need in order to improve the detrimental outcome of bacterial infections in cirrhosis.Tony Bruns Henning W Zimmermann Andreas Stallmach 2014World Journal of Gastroenterology2014,20,10:24

14Extracellular vesicle activities regulating macrophage- and tissue-mediated injury and repair responses显示文摘Macrophages are typically identified as classically activated(M1) macrophages and alternatively activated(M2) macrophages,which respectively exhibit pro-and anti-inflammatory phenotypes,and the balance between these two subtypes plays a critical role in the regulation of tissue inflammation,injury,and repair processes.Recent studies indicate that tissue cells and macrophages interact via the release of small extracellular vesicles(EVs) in processes where EVs released by stressed tissue cells can promote the activation and polarization of adjacent macrophages which can in turn release EVs and factors that can promote cell stress and tissue inflammation and injury and vice versa.This review discusses the roles of such EVs in resulating such interactions to influence tissue inflammation and injury in a number of acute and chronic inflammatory disease conditions,and the potential applications,advantage and concerns for using EV-based therapeutic approaches to treat such conditions,including their potential role of drug carriers for the treatment of infectious diseases.Qian Hu Christopher J.Lyon Jesse K.Fletcher Wenfu Tang Meihua Wan Tony Y.Hu 2021Acta Pharmaceutica Sinica B2021,11,6:22
