4Comparative review of vertebroplasty and kyphoplasty显示文摘The aim of this review is to compare the effectiveness of percutaneous vertebroplasty and kyphoplasty to treat pain and improve functional outcome from ver-tebral fractures secondary to osteoporosis and tumor conditions. In 2009, two open randomized controlled trials published in the New England Journal of Medicine questioned the value of vertebroplasty in treating ver-tebral compression fractures. Nevertheless, the prac-tice of physicians treating these conditions has barely changed. The objective of this review is to try to clarify the most important issues, based on our own experi-ence and the reported evidence about both techniques, and to guide towards the most appropriate choice of treatment of vertebral fractures, although many ques-tions still remain unanswered.Ferno Ruiz Santiago Alicia Santiago Chinchilla Luis Guzmán álvarez Antonio Luis Pérez Abela Maria del Mar Castellano García Miguel Pajares López 2014World Journal of Radiology2014,6,6:30
5尿钠排泄、血压、心血管病与死亡率的关系:社区前瞻性流行病学队列研究显示文摘WHO建议人群钠摄人<2 g/d作为预防心血管病的措施之一,但这一目标在任何国家都没有实现。该建议主要基于短期血压试验的个体水平数据,没有来自随机试验或观察性研究的关于低钠摄入与降低心血管事件的数据。前瞻性城市农村流行病学研究目前正在21个国家进行。该文对其中18个国家的数据进行分析,其中包含了临床结果数据。Mente A O'Donnell M Rangarajan S McQueen M Dagenais G Wielgosz A Lear S Ah STL Wei L Diaz R Avezum A Lopez-Jaramillo P Lanas F Mony P Szuba A Iqbal R Yusuf R Mohammadifard N Khatib R Yusoff K Ismail N Gulec S Rosengren A Yusufali A Kruger L Tsolekile LP Chifamba J Dans A Alhabib KF Yeates K Teo K Yusuf S 刘莉 叶鹏 2018中华高血压杂志2018,26,12:29
6中国两栖动物保护需求总述显示文摘通过对中国两栖动物物种生物多样性现状的全面分析,与世界许多国家相比,中国是一个重要的全球优先保护地区.横断山区、南岭山区和武夷山区3个区域的两栖动物物种多样性特别丰富.有尾两栖类物种较无尾类受胁程度更高.几个物种数相对较少的铃蟾科、隐腮鲵科、小鲵科和蝾螈科显示出了高的受胁倾向.像世界其它地方一样,高海拔地区溪流繁殖的森林物种受胁程度更高.对中国两栖动物而言,生境丧失、污染和过度捕捉是最主要的致危因素.过度捕捉虽然影响不如生境丧失深远,但它更可能导致一个物种种群的快速衰落.针对5个方面的保护挑战,提出了优先研究领域和保护行动方面的建议.谢锋 刘惠宁 Simon N Stuart Janice S Chanson Neil A Cox Debra L Fischman 2006中国科学(C辑)2006,36,6:28
7Laparoscopic and robot-assisted laparoscopic digestivesurgery:Present and future directions显示文摘Laparoscopic surgery is applied today worldwide to most digestive procedures. In some of them, such as cholecystectomy, Nissen's fundoplication or obesity surgery, laparoscopy has become the standard in practice. In others, such as colon or gastric resection, the laparoscopic approach is frequently used and its usefulness is unquestionable. More complex procedures, such as esophageal, liver or pancreatic resections are, however, more infrequently performed, due to the high grade of skill necessary. As a result, there is less clinical evidence to support its implementation. In the recent years, robot-assisted laparoscopic surgery has been increasingly applied, again with little evidence for comparison with the conventional laparoscopic approach. This review will focus on the complex digestive procedures as well as those whose use in standard practice could be more controversial. Also novel robot-assisted procedures will be updated.Juan C Rodríguez-Sanjuán Marcos Gómez-Ruiz Soledad Trugeda-Carrera Carlos Manuel-Palazuelos Antonio López-Useros Manuel Gómez-Fleitas 2016World Journal of Gastroenterology2016,22,6:27

10Metallothionein:An overview显示文摘Metallothioneins (MTs) were discovered in 1957 by Margoshes and Vallee and identified as low-molecular weight and sulphydryl rich proteins. It is not surprising that most mammalian tissues contain age related basal levels of MTs since they are involved in metalloregulatory processes that include cell growth and multiplication. In an effort to understand the biology of this intriguing tumor, various biomarkers such as oncogenes, p53 tumor suppressor gene, waf 1 protein, proliferating cell nuclear antigen, telomerase, microsatellite markers and cytogenetic changes have been examined. One biomarker which has recently shown to be expressed in various human tumors but still less reported in carcinoma is MT. Immunohistochemical detection of MT proteins in cold acetone-fixed paraffin embedded liver sections was performed by the streptavidin-avidin-biotin immuno- peroxidase complex method.N Thirumoorthy KT Manisenthil Kumar A Shyam Sundar L Panayappan Malay Chatterjee 2007World Journal of Gastroenterology2007,13,7:21
11Golgi protein-73:A biomarker for assessing cirrhosis and prognosis of liver disease patients显示文摘BACKGROUND Reliable biomarkers of cirrhosis,hepatocellular carcinoma(HCC),or progression of chronic liver diseases are missing.In this context,Golgi protein-73(GP73)also called Golgi phosphoprotein-2,was originally defined as a resident Golgi type II transmembrane protein expressed in epithelial cells.As a result,GP73 expression was found primarily in biliary epithelial cells,with only slight detection in hepatocytes.However,in patients with acute or chronic liver diseases and especially in HCC,the expression of GP73 is significantly up-regulated in hepatocytes.So far,few studies have assessed GP73 as a diagnostic or prognostic marker of liver fibrosis and disease progression.AIM To assess serum GP73 efficacy as a diagnostic marker of cirrhosis and/or HCC or as predictor of liver disease progression.METHODS GP73 serum levels were retrospectively determined by a novel GP73 ELISA(QUANTA Lite®GP73,Inova Diagnostics,Inc.,Research Use Only)in a large cohort of 632 consecutive patients with chronic viral and non-viral liver diseases collected from two tertiary Academic centers in Larissa,Greece(n=366)and Debrecen,Hungary(n=266).Aspartate aminotransferase(AST)/Platelets(PLT)ratio index(APRI)was also calculated at the relevant time points in all patients.Two hundred and three patients had chronic hepatitis B,183 chronic hepatitis C,198 alcoholic liver disease,28 autoimmune cholestatic liver diseases,15 autoimmune hepatitis,and 5 with other liver-related disorders.The duration of follow-up was 50(57)mo[median(interquartile range)].The development of cirrhosis,liver decompensation and/or HCC during follow-up were assessed according to internationally accepted guidelines.In particular,the surveillance for the development of HCC was performed regularly with ultrasound imaging and alpha-fetoprotein(AFP)determination every 6 mo in cirrhotic and every 12 mo in non-cirrhotic patients.RESULTS Increased serum levels of GP73(>20 units)were detected at initial evaluation in 277 out of 632 patients(43.8%).GP73-seropositivity correlated at baseline with the presence of cirrhosis(96.4%vs 51.5%,P<0.001),decompensation of cirrhosis(60.3%vs 35.5%,P<0.001),presence of HCC(18.4%vs 7.9%,P<0.001)and advanced HCC stage(52.9%vs 14.8%,P=0.002).GP73 had higher diagnostic accuracy for the presence of cirrhosis compared to APRI score[Area under the curve(AUC)(95%CI):0.909(0.885-0.934)vs 0.849(0.813-0.886),P=0.003].Combination of GP73 with APRI improved further the accuracy(AUC:0.925)compared to GP73(AUC:0.909,P=0.005)or APRI alone(AUC:0.849,P<0.001).GP73 levels were significantly higher in HCC patients compared to non-HCC[22.5(29.2)vs 16(20.3)units,P<0.001)and positively associated with BCLC stage[stage 0:13.9(10.8);stage A:17.1(16.8);stage B:19.6(22.3);stage C:32.2(30.8);stage D:45.3(86.6)units,P<0.001]and tumor dimensions[very early:13.9(10.8);intermediate:19.6(18.4);advanced:29.1(33.6)units,P=0.004].However,the discriminative ability for HCC diagnosis was relatively low[AUC(95%CI):0.623(0.570-0.675)].Kaplan-Meier analysis showed that the detection of GP73 in patients with compensated cirrhosis at baseline,was prognostic of higher rates of decompensation(P=0.036),HCC development(P=0.08),and liver-related deaths(P<0.001)during follow-up.CONCLUSION GP73 alone appears efficient for detecting cirrhosis and superior to APRI determination.In combination with APRI,its diagnostic performance can be further improved.Most importantly,the simple GP73 measurement proved promising for predicting a worse outcome of patients with both viral and nonviral chronic liver diseases.Nikolaos K Gatselis Tamás Tornai Zakera Shums Kalliopi Zachou Asterios Saitis Stella Gabeta Roger Albesa Gary L Norman Mária Papp George N Dalekos 2020World Journal of Gastroenterology2020,26,34:21

14Cell Death Mechanisms Induced by Cytotoxic Lymphocytes显示文摘One of the functions of the immune system is to recognize and destroy abnormal or infected cells to maintain homeostasis. This is accomplished by cytotoxic lymphocytes. Cytotoxicity is a highly organized multifactor process. Here,we reviewed the apoptosis pathways induced by the two main cytotoxic lymphocyte subsets,natural killer(NK) cells and CD8+ T cells. In base to recent experimental evidence,we reviewed NK receptors involved in recognition of target-cell,as well as lytic molecules such as perforin,granzymes-A and-B,and granulysin. In addition,we reviewed the Fas-FasL intercellular linkage mediated pathway,and briefly the cross-linking of tumor necrosis factor(TNF) and TNF receptor pathway. We discussed three models of possible molecular interaction between lytic molecules from effector cytotoxic cells and target-cell membrane to induction of apoptosis.Chávez-Galán L Arenas-Del Angel MC Zenteno E Chávez R Lascurain R 2009Cellular & Molecular Immunology2009,6,1:17
15Is rectal indomethacin effective in preventing of post-endoscopic retrograde cholangiopancreatography pancreatitis?显示文摘AIM:To investigate the effectiveness of rectally administered indomethacin in the prophylaxis of post-endoscopic retrograde cholangiopancreatography(ERCP)pancreatitis and hyperamylasaemia in a multicentre study.METHODS:A prospective,randomised,placebocontrolled multicentre study in five endoscopic units was conducted on 686 patients randomised to receive a suppository containing 100 mg indomethacin,or an inert placebo,10-15 min before ERCP.Post-ERCP pancreatitis and hyperamylasaemia were evaluated 24 h following the procedure on the basis of clinical signs and laboratory parameters,and computed tomography/magnetic resonance imaging findings if required.RESULTS:Twenty-one patients were excluded because of incompleteness of their data or because of protocol violation.The results of 665 investigations were evaluated:347 in the indomethacin group and 318 in the placebo group.The distributions of the risk factors in the two groups did not differ significantly.Pancreatitis developed in 42 patients(6.3%):it was mild in34(5.1%)and severe in eight(1.2%)cases.Hyperamylaesemia occurred in 160 patients(24.1%).There was no significant difference between the indomethacin and placebo groups in the incidence of either postERCP pancreatitis(5.8%vs 6.9%)or hyperamylasaemia(23.3%vs 24.8%).Similarly,subgroup analysis did not reveal any significant differences between the two groups.CONCLUSION:100 mg rectal indomethacin administered before ERCP did not prove effective in preventing post-ERCP pancreatitis.Zoltán Dbrnte Zoltán Szepes Ferenc Izbéki Judit Gervain László Lakatos Gyula Pécsi Miklós Ihász Lilla Lakner Erzsébet Toldy László Czakó 2014World Journal of Gastroenterology2014,20,29:16
16Systematic review and meta-analysis of colon cleansing preparations in patients with inflammatory bowel disease显示文摘AIM To performed a systematic review and meta-analysis to determine any possible differences in terms of effectiveness, safety and tolerability between existing colon-cleansing products in patients with inflammatory bowel disease.METHODS Systematic searches were performed( January 1980-September 2016) using MEDLINE, EMBASE, Scopus, CENTRAL and ISI Web of knowledge for randomized trials assessing preparations with or without adjuvants, given in split and non-split dosing, and in high(> 3 L) or low-volume(2 L or less) regimens. Bowel cleansing quality was the primary outcome. Secondary outcomes included patient willingness-torepeat the procedure and side effects/complications.RESULTS Out of 439 citations, 4 trials fulfilled our inclusion criteria(n = 449 patients). One trial assessed the impact of adding simethicone to polyethylene glycol(PEG) 4 L with no effect on bowel cleansing quality, but a better tolerance. Another trial compared senna to castor oil, again without any differences in term of bowel cleansing. Two trials compared the efficacy of PEG high-volume vs PEG low-volume associated to an adjuvant in split-dose regimens: PEG low-dose efficacy was not different to PEG high-dose; OR = 0.84(0.37-1.92). A higher proportion of patients were willing to repeat low-volume preparations vs high-volume; OR = 5.11(1.31-20.0). CONCLUSION In inflammatory bowel disease population, PEG lowvolume regimen seems not inferior to PEG high-volume to clean the colon, and yields improved willingness-torepeat. Further additional research is urgently required to compare contemporary products in this population.Sophie Restellini Omar Kherad Talat Bessissow Charles Ménard Myriam Martel Maryam Taheri Tanjani Peter L Lakatos Alan N Barkun 2017World Journal of Gastroenterology2017,23,32:16
