| 1 | Recent advances in the diagnosis and treatment of acute myocardial infarction显示文摘The Third Universal Definition of Myocardial Infarction(MI) requires cardiac myocyte necrosis with an increase and/or a decrease in a patient's plasma of cardiac troponin(cT n) with at least one cT n measurement greater than the 99 th percentile of the upper normal reference limit during:(1) symptoms of myocardialischemia;(2) new significant electrocardiogram(ECG) ST-segment/T-wave changes or left bundle branch block;(3) the development of pathological ECG Q waves;(4) new loss of viable myocardium or regional wall motion abnormality identified by an imaging procedure; or(5) identification of intracoronary thrombus by angiography or autopsy.Myocardial infarction,when diagnosed,is now classified into five types.Detection of a rise and a fall of troponin are essential to the diagnosis of acute MI.However,high sensitivity troponin assays can increase the sensitivity but decrease the specificity of MI diagnosis.The ECG remains a cornerstone in the diagnosis of MI and should be frequently repeated,especially if the initial ECG is not diagnostic of MI.There have been significant advances in adjunctive pharmacotherapy,procedural techniques and stent technology in the treatment of patients with MIs.The routine use of antiplatelet agents such as clopidogrel,prasugrel or ticagrelor,in addition to aspirin,reduces patient morbidity and mortality.Percutaneous coronary intervention(PCI) in a timely manner is the primary treatment of patients with acute ST segment elevation MI.Drug eluting coronary stents are safe and beneficial with primary coronary intervention.Treatment with direct thrombin inhibitors during PCI is non-inferior to unfractionated heparin and glycoprotein Ⅱb/Ⅲa receptor antagonists and is associated with a significant reduction in bleeding.The intra-coronary use of a glycoprotein Ⅱb/Ⅲa antagonist can reduce infarct size.Pre- and post-conditioning techniques can provide additional cardioprotection.However,the incidence and mortality due to MI continues to be high despite all these recent advances.The initial ten year experience with autologous human bone marrow mononuclear cells(BMCs) in patients with MI showed modest but significant increases in left ventricular(LV) ejection fraction,decreases in LV endsystolic volume and reductions in MI size.These studies established that the intramyocardial or intracoronary administration of stem cells is safe.However,many of these studies consisted of small numbers of patients who were not randomized to BMCs or placebo.The recent LateT ime,Time,and Swiss Multicenter Trials in patientswith MI did not demonstrate significant improvement in patient LV ejection fraction with BMCs in comparison with placebo.Possible explanations include the early use of PCI in these patients,heterogeneous BMC populations which died prematurely from patients with chronic ischemic disease,red blood cell contamination which decreases BMC renewal,and heparin which decreases BMC migration.In contrast,cardiac stem cells from the right atrial appendage and ventricular septum and apex in the SCIPIO and CADUCEUS Trials appear to reduce patient MI size and increase viable myocardium.Additional clinical studies with cardiac stem cells are in progress. | Koushik Reddy Asma Khaliq Robert J Henning | 2015 | World Journal of Cardiology2015,7,5: | 107 |

| 6 | 2018加拿大心境障碍与焦虑障碍治疗协作组/国际双相障碍学会指南:双相障碍的管理显示文摘加拿大心境障碍与焦虑障碍治疗协作组(Canadian Network for Mood and Anxiety Treatments,CANMAT)曾于2005年发布了第1版双相障碍管理指南,并分别于2007、2009和2013年对该指南进行了更新,其中最近的2次更新是与国际双相障碍学会(International Society for Bipolar Disorders,ISBD)合作完成。2018版CANMAT/ISBD双相障碍治疗指南(以下简称指南)反映了自2005年首版指南发表以来本领域取得的重大进展,包括疾病诊断与疾病管理的更新以及药物治疗与心理治疗的近期研究进展。这些前沿进展中综合考虑了循证证据的级别,并基于治疗疗效、临床实践经验、安全性、耐受性和药物导致的转相风险等,对一线、二线及三线治疗方案进行了简明而清晰的推荐。本指南中新增内容涵盖了双相Ⅰ型障碍(BD-Ⅰ)的躁狂发作急性期、抑郁发作急性期和双相障碍维持期的一线及二线治疗推荐等级划分。这种对治疗推荐等级的划分综合考虑了治疗方法对双相障碍不同时相的影响,将进一步帮助临床医生做出基于循证证据的治疗决策。锂盐、喹硫平、双丙戊酸盐、阿塞那平、阿立哌唑、帕利哌酮、利培酮和卡利拉嗪单药或联合使用被推荐为躁狂发作急性期的一线治疗选择。BD-Ⅰ抑郁期的一线治疗选择包括喹硫平、鲁拉西酮、锂盐、拉莫三嗪单药,鲁拉西酮联合锂盐或双丙戊酸盐或拉莫三嗪辅助治疗。尽管急性期治疗有效的药物通常应继续用于BD-Ⅰ的维持期治疗,但也存在一些特殊情况(例如抗抑郁药)。现有数据表明,锂盐、喹硫平、双丙戊酸盐、拉莫三嗪、阿塞那平和阿立哌唑单药或联合治疗应被视为维持治疗的初始或更换治疗方案时的一线选择。除了探讨BD-Ⅰ的相关问题外,本指南中还对双相Ⅱ型障碍(BD-Ⅱ)的临床管理进行了系统回顾并给予治疗推荐,同时针对特殊人群也有相关推荐,如处于各个生殖周期的女性、儿童、青少年和老年人。此外,本指南中还讨论了特定精神疾病及共病(如物质滥用、焦虑障碍和代谢性疾病)的影响。最后,本指南中概述了安全性和药物监测的相关问题。CANMAT/ISBD工作组希望本指南能够成为全球临床医生的实用工具。 | Lakshmi N Yatham Sidney H Kennedy Sagar V Parikh Ayal Sehaffer David J Bond Benicio N Frey Verinder Sharma Benjamin I Goldstein Soham Rej Serge Beaulieu Martin Alda Glenda MaeQueen Roumen V Milev Arun Ravindran Claire O'Donovan Diane Mclntosh Raymond W Lam Gustavo Vazquez Flavio Kapczinski Roger S Melntyre Jan Kozicky Shigenobu Kanba Beny Lafer Trisha Suppes Joseph R Calabrese Eduard Vieta Gin Malhi Robert M Post Michael Berk 胡晨(译) 王刚(译) | 2019 | 中华精神科杂志2019,52,1: | 25 |
| 7 | 2016年国际抗癫痫联盟癫痫发作分类的更新及介绍显示文摘国际抗癫痫联盟(ILAE)提出了癫痫发作类型的操作性修订方案。此修订的目的包括认识到一些发作类型既可以是局灶起源亦可以为全面起源,允许临床在不能观察到发作起源的情况下进行发作分类,纳入某些尚不了解的发作类型,以及采用更加易懂的命名。由于现有知识不足以形成一个科学的分类方案,2016年的分类方案是在1981年和2010年分类的基础上进行的操作性(实用性)修订。新分类的变化包括:(1)'部分性'改为'局灶性';(2)起源未知的癫痫发作也可以归类;(3)知觉状态用作局灶性发作的区分因素;(4)删除'认知障碍性'、'简单部分性'、'复杂部分性'、'精神性'、'继发全面性'等术语;(5)认识到局灶性强直、阵挛、失张力、肌阵挛和癫痫性痉挛发作,这些发作也有双侧性类型;(6)增加了新的全面性发作类型:伴眼睑肌阵挛的失神发作,肌阵挛失神发作,肌阵挛-失张力发作,阵挛-强直-阵挛发作,癫痫性痉挛;癫痫性痉挛可以是局灶性、全面性或起源不明性;(7)双侧强直阵挛发作取代了继发全面性发作。新的分类方案并未进行根本性的改变,但可以使癫痫发作类型的命名有较大的灵活性和透明度。 | Robert S Fisher J Helen Cross 陈佳 王玉平 吴逊 | 2017 | 癫痫杂志2017,3,1: | 25 |
| 8 | 胸腔镜肺叶切除术显示文摘背景与目的:尽管14年前我们就已报道在胸腔镜下可完成解剖意义上彻底的肺叶切除和淋巴结清扫,但关于这一术式的争论以及胸外科医师们提出的如何完成这种手术的疑问,使这种术式的被接受程度受到了限制。随着对这一术式持支持态度的人不断增多,这一术式的开展也越来越广泛。本文将讨论该术式的手术技术,临床疗效,以及关于这种术式的各种争论。方法:1992—2005年间我们共进行胸腔镜肺叶切除术1315例,其中女性700例(53.2%),男性615例(46.8%),患者平均年龄71.2岁。患者术后病理诊断:良性病变53例,肺部转移性肿瘤28例,淋巴瘤5例,肺癌1015例。腺癌在原发性肺癌中占63.1%。解剖意义上彻底的肺门切除和淋巴结活检或清扫均通过观察监视器屏幕完成,切口长约5cm,不需撑开肋骨。结果:9例(0.8%)死亡(无术中死亡及出血死亡患者)。932例(84.7%)术后没有出现并发症。1100例患者中有45例(4.1%)需输血。中位住院时间3d,平均住院时间4.78d。180例(20%)患者于术后第1天或第2天出院。28例(2.5%)患者术中转为开胸手术。5例(0.57%)患者术后切口出现复发。其中2003年内,在224例肺叶切除中89%通过胸腔镜完成。结论:在胸腔镜下可完成解剖意义上彻底的肺叶切除,且并发症率和死亡率较低。术中出血及切口复发的风险很小。 | Robert J McKenna Ward Houck 罗晓阳 | 2006 | 中国癌症杂志2006,16,8: | 20 |
| 9 | Role of ion channels in gastrointestinal cancer显示文摘In their seminal papers Hanahan and Weinberg described oncogenic processes a normal cell undergoes to be transformed into a cancer cell.The functions of ion channels in the gastrointestinal(GI)tract influence a variety of cellular processes,many of which overlap with these hallmarks of cancer.In this review we focus on the roles of the calcium(Ca^2+),sodium(Na^+),potassium(K^+),chloride(Cl^-)and zinc(Zn^2+)transporters in GI cancer,with a special emphasis on the roles of the KCNQ1 K+channel and CFTR Cl-channel in colorectal cancer(CRC).Ca^2+is a ubiquitous second messenger,serving as a signaling molecule for a variety of cellular processes such as control of the cell cycle,apoptosis,and migration.Various members of the TRP superfamily,including TRPM8,TRPM7,TRPM6 and TRPM2,have been implicated in GI cancers,especially through overexpression in pancreatic adenocarcinomas and down-regulation in colon cancer.Voltage-gated sodium channels(VGSCs)are classically associated with the initiation and conduction of action potentials in electrically excitable cells such as neurons and muscle cells.The VGSC NaV1.5 is abundantly expressed in human colorectal CRC cell lines as well as being highly expressed in primary CRC samples.Studies have demonstrated that conductance through NaV1.5 contributes significantly to CRC cell invasiveness and cancer progression.Zn2+transporters of the ZIP/SLC39A and ZnT/SLC30A families are dysregulated in all major GI organ cancers,in particular,ZIP4 up-regulation in pancreatic cancer(PC).More than 70 K+channel genes,clustered in four families,are found expressed in the GI tract,where they regulate a range of cellular processes,including gastrin secretion in the stomach and anion secretion and fluid balance in the intestinal tract.Several distinct types of K+channels are found dysregulated in the GI tract.Notable are hERG1 upregulation in PC,gastric cancer(GC)and CRC,leading to enhanced cancer angiogenesis and invasion,and KCNQ1 down-regulation in CRC,where KCNQ1 expression is associated with enhanced disease-free survival in stage II,III,and IV disease.Cl-channels are critical for a range of cellular and tissue processes in the GI tract,especially fluid balance in the colon.Most notable is CFTR,whose deficiency leads to mucus blockage,microbial dysbiosis and inflammation in the intestinal tract.CFTR is a tumor suppressor in several GI cancers.Cystic fibrosis patients are at a significant risk for CRC and low levels of CFTR expression are associated with poor overall disease-free survival in sporadic CRC.Two other classes of chloride channels that are dysregulated in GI cancers are the chloride intracellular channels(CLIC1,3&4)and the chloride channel accessory proteins(CLCA1,2,4).CLIC1&4 are upregulated in PC,GC,gallbladder cancer,and CRC,while the CLCA proteins have been reported to be down-regulated in CRC.In summary,it is clear,from the diverse influences of ion channels,that their aberrant expression and/or activity can contribute to malignant transformation and tumor progression.Further,because ion channels are often localized to the plasma membrane and subject to multiple layers of regulation,they represent promising clinical targets for therapeutic intervention including the repurposing of current drugs. | Kyle J Anderson Robert T Cormier Patricia M Scott | 2019 | World Journal of Gastroenterology2019,25,38: | 19 |

| 11 | Mechanisms underlying feed intolerance in the critically ill: Implications for treatment显示文摘Malnutrition is associated with poor outcomes in critically ill patients. Although nutritional support is yet to be proven to improve mortality in non-malnourished critically ill patients, early enteral feeding is considered best practice. However, enteral feeding is often limited by delayed gastric emptying. The best method to clinically identify delayed gastric emptying and feed intolerance is unclear. Gastric residual volume (GRV) measured at the bedside is widely used as a surrogate marker for gastric emptying, but the value of GRV measurement has recently been disputed. While the mechanisms underlying delayed gastric emptying require further investigation, recent research has given a better appreciation of the pathophysiology. A number of pharmacological strategies are available to improve the success of feeding. Recent data suggest a combination of intravenous metoclopramide and erythromycin to be the most successful treatment, but novel drug therapies should be explored. Simpler methods to access the duodenum and more distal small bowel for feed delivery are also under investigation. This review summarises current understanding of the factors responsible for, and mechanisms underlying feed intolerance in critical illness, together with the evidence for current practices. Areas requiring further research are also highlighted. | Adam Deane Marianne J Chapman Robert J Fraser Laura K Bryant Carly Burgstad Nam Q Nguyen | 2007 | World Journal of Gastroenterology2007,13,29: | 18 |

| 13 | Obesity and non-alcoholic fatty liver disease: Disparate associations among asian populations显示文摘obesity is a global epidemic contributing to an increas-ing prevalence of obesity-related systemic disorders, including nonalcoholic fatty liver disease. The rising prevalence of nonalcoholic steatohepatitis(NASh) will in the near future lead to end-stage liver disease in a large cohort of patients with NASh-related cirrhosis and NASh is predicted to be a leading indication for liver transplantation in the coming decade. however, the prevalence of obesity and the progression of hepatic histological damage associated with NASh exhibit sig-nificant ethnic disparities. Despite a significantly lower body mass index and lower rates of obesity compared to other ethnic groups, Asians continue to demonstrate a significant prevalence of hypertension, diabetes, met-abolic syndrome and NASh. Ethnic disparities in central adiposity and visceral fat distribution have been hy-pothesized to contribute to these ethnic disparities. The current review focuses on the epidemiology of obesity and NASh among Asian populations. | Robert J Wong Aijaz Ahmed | 2014 | World Journal of Hepatology2014,6,5: | 15 |

| 15 | Radioembolization for the treatment of unresectable hepatocellular carcinoma:A clinical review显示文摘Hepatocellular carcinoma(HCC)is the sixth most common cancer in the world.The majority of patients with HCC present with unresectable disease.These patients have historically had limited treatment options secondary to HCC demonstrating chemoresistance to the currently available systemic therapies.Additionally, normal liver parenchyma has shown intolerance to tumoricidal radiation doses,limiting the use of external beam radiation.Because of these limitations,novel percutaneous liver-directed therapies have emerged. The targeted infusion of radioactive microspheres (radioembolization)represents one such therapy. Radioembolization is a minimally invasive transcatheter therapy through which radioactive microspheres are infused into the hepatic arteries that supply tumor. Once infused,these microspheres traverse the hepatic vascular plexus and selectively implant within the tumor arterioles.Embedded within the arterioles, the 90Y impregnated microspheres emit high energy and low penetrating radiation doses selectively to the tumor.Radioembolization has recently shown promise for the treatment of patients with unresectable HCC. The objective of this review article is to highlight twocurrently available radioembolic devices(90Y,188Rh)and provide the reader with a recent review of the literature. | Saad M Ibrahim Robert J Lewandowski Kent T Sato Vanessa L Gates Laura Kulik Mary F Mulcahy Robert K Ryu Reed A Omary Riad Salem | 2008 | World Journal of Gastroenterology2008,14,11: | 14 |

| 18 | Surveillance-response systems: the key to elimination of tropical diseases显示文摘Tropical diseases remain a major cause of morbidity and mortality in developing countries.Although combined health efforts brought about significant improvements over the past 20 years,communities in resource-constrained settings lack the means of strengthening their environment in directions that would provide less favourable conditions for pathogens.Still,the impact of infectious diseases is declining worldwide along with progress made regarding responses to basic health problems and improving health services delivery to the most vulnerable populations.The London Declaration on Neglected Tropical Diseases(NTDs),initiated by the World Health Organization’s NTD roadmap,set out the path towards control and eventual elimination of several tropical diseases by 2020,providing an impetus for local and regional disease elimination programmes.Tropical diseases are often patchy and erratic,and there are differing priorities in resources-limited and endemic countries at various levels of their public health systems.In order to identify and prioritize strategic research on elimination of tropical diseases,the‘First Forum on Surveillance-Response System Leading to Tropical Diseases Elimination’was convened in Shanghai in June 2012.Current strategies and the NTD roadmap were reviewed,followed by discussions on how to identify and critically examine prevailing challenges and opportunities,including inter-sectoral collaboration and approaches for elimination of several infectious,tropical diseases.A priority research agenda within a‘One Health-One World’frame of global health was developed,including(i)the establishment of a platform for resource-sharing and effective surveillance-response systems for Asia Pacific and Africa with an initial focus on elimination of lymphatic filariasis,malaria and schistosomiasis;(ii)development of new strategies,tools and approaches,such as improved diagnostics and antimalarial therapies;(iii)rigorous validation of surveillance-response systems;and(iv)designing pilot studies to transfer Chinese experiences of successful surveillance-response systems to endemic countries with limited resources. | Ernest Tambo Lin Ai Xia Zhou Jun-Hu Chen Wei Hu Robert Bergquist Jia-Gang Guo Jürg Utzinger Marcel Tanner Xiao-Nong Zhou | 2014 | Infectious Diseases of Poverty2014,3,1: | 14 |
| 19 | Diffusion-weighted magnetic resonance imaging to predict response of hepatocellular carcinoma to chemoembolization显示文摘AIM: To investigate whether intra-procedural diffusion- weighted magnetic resonance imaging can predict response of hepatocellular carcinoma (HCC) during trans- catheter arterial chemoembolization (TACE). METHODS: Sixteen patients (15 male), aged 59 ±11 years (range: 42-81 years) underwent a total of 21 separate treatments for unresectable HCC in a hybrid magnetic resonance/interventional radiology suite. Ana- tomical imaging and diffusion-weighted imaging (b = 0, 500 s/mm2) were performed on a 1.5-T unit. Tumor enhancement and apparent diffusion coefficient (ADC, mm2/s) values were assessed immediately before and at 1 and 3 mo after TACE. We calculated the percent change (PC) in ADC values at all time points. We compared follow-up ADC values to baseline values using a paired t test (α = 0.05). RESULTS: The intra-procedural sensitivity, specificity, and positive and negative predictive values (%) for detecting a complete or partial 1-mo tumor response using ADC PC thresholds of ±5%, ±10%, and ±15% were 77, 67, 91, and 40; 54, 67, 88, and 25; and 46, 100, 100, and 30, respectively. There was no clear predictive value for the 3-mo follow-up. Compared to baseline, the immediate post-procedure and 1-mo mean ADC values both increased; the latter obtaining statistical significance (1.48 ± 0.29 mm2/s vs 1.65 ± 0.35 × 10-3 mm2/s, P < 0.014). CONCLUSION: Intra-procedural ADC changes of > 15% predicted 1-mo anatomical HCC response with the greatest accuracy, and can provide valuable feedback at the time of TACE. | Johnathan C Chung Neel K Naik Robert J Lewandowski Mary F Mulcahy Laura M Kulik Kent T Sato Robert K Ryu Riad Salem Andrew C Larson Reed A Omary | 2010 | World Journal of Gastroenterology2010,16,25: | 13 |
| 20 | Increased hepcidin expression in colorectal carcinogenesis显示文摘AIM:To investigate whether the iron stores regulator hepcidin is implicated in colon cancer-associated anae- mia and whether it might have a role in colorectal car- cinogenesis. METHODS: Mass spectrometry (MALDI-TOF MS and SELDI-TOF MS) was employed to measure hepcidin in urine collected from 56 patients with colorectal cancer. Quantitative Real Time RT-PCR was utilised to determine hepcidin mRNA expression in colorectal cancer tissue. Hepcidin cellular localisation was determined using im- munohistochemistry. RESULTS: We demonstrate that whilst urinary hepcidin expression was not correlated with anaemia it was posi- tively associated with increasing T-stage of colorectal cancer (P < 0.05). Furthermore, we report that hepcidin mRNA is expressed in 34% of colorectal cancer tissue specimens and was correlated with ferroportin repres- sion. This was supported by hepcidin immunoreactivity in colorectal cancer tissue. CONCLUSION: We demonstrate that systemic hepcidin expression is unlikely to be the cause of the systemic anaemia associated with colorectal cancer. However, we demonstrate for the first time that hepcidin is expressed by colorectal cancer tissue and that this may represent a novel oncogenic signalling mechanism. | Douglas G Ward Keith Roberts Matthew J Brookes Howard Joy Ashley Martin Tariq Ismail Robert Spychal Tariq Iqbal Chris Tselepis | 2008 | World Journal of Gastroenterology2008,14,9: | 12 |
