| 1 | Diabetic nephropathy and inflammation显示文摘Diabetic nephropathy(DN) is the leading cause of end-stage renal failure worldwide. Besides, diabetic nephropathy is associated with cardiovascular disease, and increases mortality of diabetic patients. Several factors are involved in the pathophysiology of DN, including metabolic and hemodynamic alterations, oxidative stress, and activation of the renin-angiotensin system. In recent years, new pathways involved in the development and progression of diabetic kidney disease have been elucidated; accumulated data have emphasized the critical role of inflammation in the pathogenesis of diabetic nephropathy. Expression of cell adhesion molecules, growth factors, chemokines and pro-inflammatory cytokines are increased in the renal tissues of diabetic patients, and serum and urinary levels of cytokines and cell adhesion molecules, correlated with albuminuria. In this paper we review the role of inflammation in the development of diabetic nephropathy, discussing some of the major inflammatory cytokines involved in the pathogenesis of diabetic nephropathy, including the role of adipokines, and take part in other mediators of inflammation, as adhesion molecules. | Montserrat B Duran-Salgado Alberto F Rubio-Guerra | 2014 | World Journal of Diabetes2014，5，3： | 169 |
| 2 | Liver cirrhosis and diabetes:Risk factors,pathophysiology,clinical implications and management显示文摘About 30% of patients with cirrhosis have diabetes mellitus(DM).Nowadays,it is a matter for debate whether type 2 DM in the absence of obesity and hypertriglyceridemia may be a risk factor for chronic liver disease.DM,which develops as a complication of cirrhosis,is known as 'hepatogenous diabetes'.Insulin resistance in muscular and adipose tissues and hyperinsulinemia seem to be the pathophysiologic bases of diabetes in liver disease.An impaired response of the islet β-cells of the pancreas and hepatic insulin resistance are also contributory factors.Non-alcoholic fatty liver disease,alcoholic cirrhosis,chronic hepatitis C(CHC) and hemochromatosis are more frequently associated with DM.Insulin resistance increases the failure of the response to treatment in patients with CHC and enhances progression of fibrosis.DM in cirrhotic patients may be subclinical.Hepatogenous diabetes is clinically different from that of type 2 DM,since it is less frequently associated with microangiopathy and patients more frequently suffer complications of cirrhosis.DM increases the mortality of cirrhotic patients.Treatment of the diabetes is complex due to liver damage and hepatotoxicity of oral hypoglycemic drugs.This manuscript will review evidence that exists in relation to:type 2 DM alone or as part of the metabolic syndrome in the development of liver disease;factors involved in the genesis of hepatogenous diabetes;the impact of DM on the clinical outcome of liver disease;the management of DM in cirrhotic patients and the role of DM as a risk factor for the occurrence and exacerbation of hepatocellular carcinoma. | Diego Garcia-Compean Joel Omar Jaquez-Quintana Jose Alberto Gonzalez-Gonzalez Hector Maldonado-Garza | 2009 | World Journal of Gastroenterology2009，15，3： | 112 |
| 3 | 一种基于高斯混合模型的轨迹预测算法显示文摘在智能交通控制系统、军事数字化战场、辅助驾驶系统中,实时、精确、可靠的移动对象不确定性轨迹预测具有极高的应用价值.智能轨迹预测不仅可以提供精准的基于位置的服务,而且可以提前监测和预判交通状况,进而推荐最佳路线,已经成为移动对象数据库研究的热点,亟需设计准确而高效的位置预测方法.针对现有方法的不足,提出了基于高斯混合模型的轨迹预测方法 GMTP,主要步骤包括:(1)针对复杂运动模式利用高斯混合模型建模;(2)利用高斯混合模型计算不同运动模式的概率分布,进而将轨迹数据划分为不同分量;(3)利用高斯过程回归预测移动对象最可能的运动轨迹.GMTP是高斯非线性概率统计模型,其优势在于:计算结果不仅是位置预测值,更是关于移动对象未来所有可能运动轨迹的概率分布,可以利用概率统计分布特性获得某种运动模式(如匀加速运动)下的位置预测.大量真实轨迹数据集上的实验结果表明:与相同参数设置下的高斯回归预测和卡尔曼滤波预测法相比,GMTP的预测准确性平均提高了22.2%和23.8%,预测时间平均缩减了92.7%和95.9%. | 乔少杰 金琨 韩楠 唐常杰 格桑多吉 Louis Alberto GUTIERREZ | 2015 | 软件学报2015，26，5： | 111 |
| 4 | Pathophysiological 角色和在糖尿病的 nephropathy 的发炎的治疗学的含意显示文摘 Diabetes mellitus and its complications are becoming one of the most important health problems in the world. Diabetic nephropathy is now the main cause of end-stage renal disease. The mechanisms leading tothe development and progression of renal injury are not well known. Therefore, it is very important to f ind new pathogenic pathways to provide opportunities for early diagnosis and targets for novel treatments. At the present time, we know that activation of innate immunity with development of a chronic low grade inflammatory response is a recognized factor in the pathogenesis of diabetic nephropathy. Numerous experimental and clinical studies have shown the participation of different inflammatory molecules and pathways in the pathophysiology of this complication. | Desirée Luis-Rodríguez Alberto Martínez-Castelao José Luis Górriz Fernando de lvaro Juan F Navarro-González | 2012 | World Journal of Diabetes2012，3，1： | 55 |
| 5 | Nitrosamine and related food intake and gastric and oesophageal cancer risk: A systematic review of the epidemiological evidence显示文摘瞄准:学习在亚硝酸根和亚硝基胺吸入和胃的癌症(GC ) 之间的协会在肉和处理的肉吸入之间, GC 和食道的癌症(OC ) ,并且在保存的鱼,蔬菜和吸的食物摄取和 GC 之间。方法:在这篇文章,我们从 1985-2005 考察了所有出版的队和盒子控制研究,并且分析了在亚硝基胺和亚硝酸根吸入和最重要的相关食物摄取(喝的肉和处理的肉,保存蔬菜和鱼,吸的食物和啤酒) 和 GC 或 OC 风险之间的关系。61 研究, 11 个队和 50 盒子控制研究被包括。结果:从盒子控制研究的证据与 GC 支持了在亚硝酸根和亚硝基胺吸入之间的一个协会,但是证据在与 OC 的关系是不够的。盒子控制研究的一个高比例为两个瘤(GC 上的 16 研究中的 11 个和 OC 上的 18 研究中的 11 个) 与肉吸入发现了一个积极协会。盒子控制研究的一个相对大的数字显示出支持在处理的肉吸入和 GC 和 OC 风险之间的一个积极协会的相当一致的结果(GC 上的 14 研究中的 10 个和 9 中的 8 个在 OC 上学习) 。几乎所有盒子控制研究发现了在保存的鱼,蔬菜和吸的食物摄取和 GC 之间的一个积极、重要的协会。关于 OC 的证据是更有限的。从队的证据学习的外套从盒子控制研究比那不够或更不一致。结论:可得到的证据支持在亚硝酸根和亚硝基胺吸入和 GC 之间的一个积极协会,在肉和处理的肉吸入和 GC 和 OC 之间,并且在保存的鱼,蔬菜和吸的食物摄取和 GC 之间,但是不是最后的。 | Paula Jakszyn Carlos Alberto González | 2006 | World Journal of Gastroenterology2006，12，27： | 42 |

| 7 | Aggressive blood pressure treatment of hypertensive intracerebral hemorrhage may lead to global cerebral hypoperfusion:Case report and imaging perspective显示文摘Hypoperfusion injury related to blood pressure decrease in acute hypertensive intracerebral hemorrhage continues to be a controversial topic. Aggressive treatment is provided with the intent to stop the ongoing bleeding. However, there may be additional factors, including autoregulation and increased intracranial pressure, that may limit this approach. We present here a case of acute hypertensive intracerebral hemorrhage, in which aggressive blood pressure management to levels within the normal range led to global cerebral ischemia within multiple border zones. Global cerebral ischemia may be of concern in the management of hypertensive hemorrhage in the presence of premorbid poorly controlled blood pressure and increased intracranial pressure. | Jose Gavito-Higuera Rakesh Khatri Ihtesham A Qureshi Alberto Maud Gustavo J Rodriguez | 2017 | World Journal of Radiology2017，9，12： | 49 |
| 8 | Two-dimensional speckle tracking echocardiography for the assessment of atrial function显示文摘Echocardiography is the most common diagnostic method for assessing atrial function but the technique has some limitations. Traditionally, assessment of left atrial function has been performed by measuring volumes with 2D echocardiography. Additionally, it can be assessed with transmitral Doppler and pulmonary vein Doppler. Recently, an alternative method has been incorporated, namely, measurement of myocardial deformation with color tissue Doppler-derived strain. However, this method has several limitations, such as suboptimal reproducibility, angle-dependence, signal artifacts and the fact that it only measures regional strain and does not obtain information about the curved portion of the atrial roof. To overcome these limitations in the quantification of atrial function, the use of speckle tracking echocardiography (STE) strain has been proposed. This technique is not derived from Doppler but rather from 2D echocardiography; it is angle-independent and allows one to measure global as well as regional atrial strain. In this editorial, we describe the physical and pathophysiological concepts of STE and underline the clinical usefulness of this new technique. | Tomás Francisco Cianciulli María Cristina Saccheri Jorge Alberto Lax Alejandra Marina Bermann Daniel Ernesto Ferreiro | 2010 | World Journal of Cardiology2010，2，7： | 39 |
| 9 | Short-chain fatty acids act as antiinflammatory mediators by regulating prostaglandin E_2 and cytokines显示文摘AIM:To investigate the effect of short-chain fatty ac-ids (SCFAs) on production of prostaglandin E2 (PGE2),cytokines and chemokines in human monocytes.METHODS:Human neutrophils and monocytes were isolated from human whole blood by using 1-Step Polymorph and RosetteSep Human Monocyte Enrich-ment Cocktail,respectively. Human GPR41 and GPR43 mRNA expression was examined by quantitative real-time polymerase chain reaction. The calcium flux assay was used to examine the biological activities of SCFAs in human neutrophils and monocytes. The effect ofSCFAs on human monocytes and peripheral blood mononuclear cells (PBMC) was studied by measuring PGE2,cytokines and chemokines in the supernatant. The effect of SCFAs in vivo was examined by intraplantar injection into rat paws.RESULTS:Human GPR43 is highly expressed in human neutrophils and monocytes. SCFAs induce robust calcium flux in human neutrophils,but not in human monocytes. In this study,we show that SCFAs can in-duce human monocyte release of PGE2 and that this effect can be enhanced in the presence of lipopolysac-charide (LPS). In addition,we demonstrate that PGE2 production induced by SCFA was inhibited by pertussis toxin,suggesting the involvement of a receptor-mediated mechanism. Furthermore,SCFAs can specifi cally inhibit constitutive monocyte chemotactic protein-1 (MCP-1) production and LPS-induced interleukin-10 (IL-10) production in human monocytes without affecting the secretion of other cytokines and chemokines examined. Similar activities were observed in human PBMC for the release of PGE2,MCP-1 and IL-10 after SCFA treatment. In addition,SCFAs inhibit LPS-induced production of tumor necrosis factor-α and interferon-γ in human PBMC. Finally,we show that SCFAs and LPS can induce PGE2 production in vivo by intraplantar injection into rat paws (P < 0.01). CONCLUSION:SCFAs can have distinct antiinflammatory activities due to their regulation of PGE2,cytokine and chemokine release from human immune cells. | Mary Ann Cox James Jackson Michaela Stanton Alberto Rojas-Triana Loretta Bober Maureen Laverty Xiaoxin Yang Feng Zhu Jianjun Liu Suke Wang Frederick Monsma Galya Vassileva Maureen Maguire Eric Gustafson Marvin Bayne Chuan-Chu Chou Daniel Lundell Chung-Her Jenh | 2009 | World Journal of Gastroenterology2009，15，44： | 30 |
| 10 | Gastric cancer: Current status of lymph node dissection显示文摘D2 procedure has been accepted in Far East as the standard treatment for both early(EGC) and advanced gastric cancer(AGC) for many decades. Recently EGC has been successfully treated with endoscopy by endoscopic mucosal resection or endoscopic submucosal dissection, when restricted or extended Gotoda's criteria can be applied and D1+ surgery is offered only to patients not fitted for less invasive treatment. Furthermore, two randomised controlled trials(RCTs) have been demonstrating the non inferiority of minimally invasive technique as compared to standard open surgery for the treatment of early cases and recently the feasibility of adequate D1+ dissection has been demonstrated also for the robot assisted technique. In case of AGC the debate on the extent of nodal dissection has been open for many decades. While D2 gastrectomy was performed as the standard procedure in eastern countries, mostly based on observational and retrospective studies, in the west the Medical Research Council(MRC), Dutch and Italian RCTs have been conducted to show a survival benefit of D2 over D1 with evidence based medicine. Unfortunately both the MRC and the Dutch trials failed to show a survival benefit after the D2 procedure, mostly due to the significant increase of postoperative morbidity and mortality, which was referred to splenopancreatectomy. Only 15 years after the conclusion of its accrual, the Dutch trial could report a significant decrease of recur-rence after D2 procedure. Recently the long term survival analysis of the Italian RCT could demonstrate a benefit for patients with positive nodes treated with D2 gastrectomy without splenopancreatectomy. As nowadays also in western countries D2 procedure can be done safely with pancreas preserving technique and without preventive splenectomy, it has been suggested in several national guidelines as the recommended procedure for patients with AGC. | Maurizio Degiuli Giovanni De Manzoni Alberto Di Leo Domenico D'Ugo Erica Galasso Daniele Marrelli Roberto Petrioli Karol Polom Franco Roviello Francesco Santullo Mario Morino | 2016 | World Journal of Gastroenterology2016，22，10： | 29 |
| 11 | Immune regulatory properties of multipotent mesenchymal stromal cells:Where do we stand?显示文摘Multipotent mesenchymal stromal cells (MSC) can be isolated and efficiently expanded from almost every single body tissue and have the ability of self-renewal and differentiation into various mesodermal cell lineages. Moreover, these cells are considered immunologically privileged, related to a lack of surface expression of costimulatory molecules required for complete T cell activation. Recently, it has been observed that MSC are capable of suppressing the immune response by inhibiting the maturation of dendritic cells and suppressing the function of T lymphocytes, B lymphocytes and natural killer cells in autoimmune and inflammatory diseases as a new strategy for immunosuppression. The understanding of immune regulation mechanisms by MSC is necessary for their use as immunotherapy in clinical applications for several diseases. | ênio José Bassi Carlos Alberto Mayora Aita Niels Olsen Saraiva Camara | 2011 | World Journal of Stem Cells2011，3，1： | 27 |
| 12 | Acute recurrent pancreatitis:Etiopathogenesis, diagnosis and treatment显示文摘Acute recurrent pancreatitis(ARP)refers to a clinical entity characterized by episodes of acute pancreatitis which occurs on more than one occasion.Recurrence of pancreatitis generally occurs in a setting of normal morpho-functional gland,however,an established chronic disease may be found either on the occasion of the first episode of pancreatitis or during the follow-up.The aetiology of ARP can be identified in the majority of patients.Most common causes include common bile duct stones or sludge and bile crystals;sphincter of oddi dysfunction;anatomical ductal variants interfering with pancreatic juice outflow;obstruction of the main pancreatic duct or pancreatico-biliary junction;genetic mutations;alcohol consumption.However,despite diagnostic technologies,the aetiology of ARP still remains unknown in up to 30%of cases:in these cases the term'idiopathic'is used.Because occult bile stone disease and sphincter of oddi dysfunction account for the majority of cases,cholecystectomy,and eventually the endoscopic biliary and/or pancreatic sphincterotomy are curative in most of cases.Endoscopic biliary sphincterotomy appeared to be a curative procedure per se in about 80%of patients.Ursodeoxycholic acid oral treatment alone has also been reported effective for treatment of biliary sludge.In uncertain cases toxinbotulin injection may help in identifying some sphincter of oddi dysfunction,but this treatment is not widely used.In the last twenty years,pancreatic endotherapy has been proven effective in cases of recurrent pancreatitis depending on pancreatic ductal obstruction,independently from the cause of obstruction,and has been widely used instead of more aggressive approaches. | Pier Alberto Testoni | 2014 | World Journal of Gastroenterology2014，20，45： | 27 |

| 15 | H pylori infection and systemic antibodies to CagA and heat shock protein 60 in patients with coronary heart disease显示文摘AIM: To determine the overall prevalence of H pylori and CagA positive H pylori infection and the prevalence of other bacterial and viral causes of chronic infection in patients with coronary heart disease (CHD), and the potential role of anti-heat-shock protein 60 (Hsp60) anti- body response to these proteins in increasing the risk of CHD development. METHODS: Eighty patients with CHD and 160 controls were employed. We also compared the levels of anti- heat-shock protein 60 (Hsp60) antibodies in the two groups. The H pylori infection and the CagA status were determined serologically, using commercially available enzyme-linked immunosorbent assays (ELISA), and a Western blotting method developed in our laboratory. Systemic antibodies to Hsp60 were determined by a sandwich ELISA, using a polyclonal antibody to Hsp60 to sensitise polystyrene plates and a commercially available human Hsp60 as an antigen. RESULTS: The overall prevalence of H pylori infec- tion was 78.7% (n = 63) in patients and 76.2% (n = 122) in controls (P = 0.07). Patients infected by CagA- positive (CagA+) H pylori strains were 71.4% (n = 45) vs 52.4% of infected controls (P = 0.030, OR = 2.27). Sys-temic levels of IgG to Hsp60 were increased in H pylori- negative patients compared with uninfected controls (P < 0.001) and CagA-positive infected patients compared with CagA-positive infected controls (P = 0.007). CONCLUSION: CagA positive H pylori infection may concur to the development of CHD; high levels of anti- Hsp60 antibodies may constitute a marker and/or a con- comitant pathogenic factor of the disease. | Cristina Lenzi Alberto Palazzuoli Nicola Giordano Giuliano Alegente Catia Gonnelli Maria Stella Campagna Annalisa Santucci Michele Sozzi Panagiotis Papakostas Fabio Rollo Ranuccio Nuti Natale Figura | 2006 | World Journal of Gastroenterology2006，12，48： | 23 |
| 16 | Outcomes of robotic vs laparoscopic hepatectomy:A systematic review and meta-analysis显示文摘AIM: To perform a systematic review and metaanalysis on robotic-assisted vs laparoscopic liver resections.METHODS: A systematic literature search was performed using Pub Med, Scopus and the Cochrane Library Central. Participants of any age and sex, who underwent robotic or laparoscopic liver resection were considered following these criteria:(1) studies comparing robotic and laparoscopic liver resection;(2) studies reporting at least one perioperative outcome; and(3) if more than one study was reported by the same institute, only the most recent was included. The primary outcome measures were set for estimated blood loss, operative time, conversion rate, R1 resection rate, morbidity and mortality rates, hospital stay and major hepatectomy rates.RESULTS: A total of 7 articles, published between 2010 and 2014, fulfilled the selection criteria. The laparoscopic approach was associated with a significant reduction in blood loss and lower operative time(MD = 83.96, 95%CI: 10.51-157.41, P = 0.03; MD = 68.43, 95%CI: 39.22-97.65, P < 0.00001, respectively). No differences were found with respect to conversion rate, R1 resection rate, morbidity and hospital stay.CONCLUSION: Laparoscopic liver resection resulted in reduced blood loss and shorter surgical times compared to robotic liver resections. There was no difference in conversion rate, R1 resection rate, morbidity and length of postoperative stay. | Roberto Montalti Giammauro Berardi Alberto Patriti Marco Vivarelli Roberto Ivan Troisi | 2015 | World Journal of Gastroenterology2015，21，27： | 22 |
| 17 | Robot-assisted laparoscopic vs open gastrectomy for gastric cancer:Systematic review and meta-analysis显示文摘AIM To evaluate the potential effectiveness of robot-assisted gastrectomy(RAG) in comparison to open gastrectomy(OG) for gastric cancer patients.METHODS A comprehensive systematic literature search using PubM ed,EMBASE,and the Cochrane Library was carried out to identify studies comparing RAG and OG in gastric cancer.Participants of any age and sex were considered for inclusion in comparative studies of the two techniques independently from type of gastrectomy.A meta-analysis of short-term perioperative outcomes was performed to evaluate whether RAG is equivalent to OG.The primary outcome measures were set for estimated blood loss,operative time,conversion rate,morbidity,and hospital stay.Secondary among postoperative complications,wound infection,bleeding and anastomotic leakage were also analysed.RESULTS A total of 6 articles,5 retrospective and 1 randomized controlled study,involving 6123 patients overall,with 689(11.3%) cases submitted to RAG and 5434(88.7%) to OG,satisfied the eligibility criteria and were included in the meta-analysis.RAG was associated with longer operation time than OG(weighted mean difference 72.20 min;P < 0.001),but with reduction in blood loss and shorter hospital stay(weighted mean difference-166.83 mL and-1.97 d respectively;P < 0.001).No differences were found with respect to overall postoperative complications(P = 0.65),wound infection(P = 0.35),bleeding(P = 0.65),and anastomotic leakage(P = 0.06).The postoperative mortality rates were similar between the two groups.With respect to oncological outcomes,no statistical differences among the number of harvested lymph nodes were found(weighted mean difference-1.12;P = 0.10).CONCLUSION RAG seems to be a technically valid alternative to OG for performing radical gastrectomy in gastric cancer resulting in safe complications. | Stefano Caruso Alberto Patriti Franco Roviello Lorenzo De Franco Franco Franceschini Graziano Ceccarelli Andrea Coratti | 2017 | World Journal of Clinical Oncology2017，8，3： | 23 |
| 18 | Laparoscopic and robot-assisted gastrectomy for gastric cancer: Current considerations显示文摘Radical gastrectomy with an adequate lymph-adenectomy is the main procedure which makes it possible to cure patients with resectable gastric cancer(GC). A number of randomized controlled trials and meta-analysis provide phase Ⅲ evidence that laparoscopic gastrectomy is technically safe and that it yields better short-term outcomes than conventional open gastrectomy for early-stage GC. While laparoscopic gastrectomy has become standard therapy for early-stage GC, especially in Asian countries such as Japan and South Korea, the use of minimally invasive techniques is still controversial for the treatment of more advanced tumours, principally due to existing concerns about its oncological adequacy and capacity to carry out an adequately extended lymphadenectomy. Some intrinsic drawbacks of the conventional laparoscopic technique have prevented the worldwide spread of laparoscopic gastrectomyfor cancer and, despite technological advances in recent year, it remains a technically challenging procedure. The introduction of robotic surgery over the last ten years has implied a notable mutation of certain minimally invasive procedures, making it possible to overcome some limitations of the traditional laparoscopic technique. Robot-assisted gastric resection with D2 lymph node dissection has been shown to be safe and feasible in prospective and retrospective studies. However, to date there are no high quality comparative studies investigating the advantages of a robotic approach to GC over traditional laparoscopic and open gastrectomy. On the basis of the literature review here presented, robot-assisted surgery seems to fulfill oncologic criteria for D2 dissection and has a comparable oncologic outcome to traditional laparoscopic and open procedure. Robot-assisted gastrectomy was associated with the trend toward a shorter hospital stay with a comparable morbidity of conventional laparoscopic and open gastrectomy, but randomized clinical trials and longer follow-ups are needed to evaluate the possible influence of robot gastrectomy on GC patient survival. | Stefano Caruso Alberto Patriti Franco Roviello Lorenzo De Franco Franco Franceschini Andrea Coratti Graziano Ceccarelli | 2016 | World Journal of Gastroenterology2016，22，25： | 23 |
| 19 | Splanchnic vasodilation and hyperdynamic circulatory syndrome in cirrhosis显示文摘Portal hypertension is a clinical syndrome which leads to several clinical complications,such as the formation and rupture of esophageal and/or gastric varices,ascites,hepatic encephalopathy and hepato-renal syndrome.In cirrhosis,the primary cause of the increase in portal pressure is the enhanced resistance to portal outflow.However,also an increase in splanchnic blood flow worsens and maintains portal hypertension.The vasodilatation of arterial splanchnic vessels and the opening of collateral circulation are the determinants of the increased splanchnic blood flow.Several vasoactive systems/substances,such as nitric oxide,cyclooxygenase-derivatives,carbon monoxide and endogenous cannabinoids are activated in portal hypertension and are responsible for the marked splanchnic vasodilatation.Moreover,an impaired reactivity to vasoconstrictor systems,such as the sympathetic nervous system,vasopressin,angiotensinⅡand endothelin-1,plays a role in this process.The opening of collateral circulation occurs through the reperfusion and dilatation of preexisting vessels,but also through the generation of new vessels.Splanchnic vasodilatation leads to the onset of the hyperdynamic circulatory syndrome,a syndrome which occurs in pa-tients with portal hypertension and is characterized by increased cardiac output and heart rate,and decreased systemic vascular resistance with low arterial blood pressure.Understanding the pathophysiology of splanchnic vasodilatation and hyperdynamic circulatory syndrome is mandatory for the prevention and treatment of portal hypertension and its severe complications. | Massimo Bolognesi Marco Di Pascoli Alberto Verardo Angelo Gatta | 2014 | World Journal of Gastroenterology2014，20，10： | 21 |
