| 1 | Acute pancreatitis at the beginning of the 21st century: The state of the art显示文摘Acute pancreatitis is an acute inflammatory disease of the pancreas which can lead to a systemic inflammatory response syndrome with significant morbidity and mortality in 20% of patients. Gallstones and alcohol consumption are the most frequent causes of pancreatitis in adults. The treatment of mild acute pancreatitis is conservative and supportive; however severe episodes characterized by necrosis of the pancreatic tissue may require surgical intervention. Advanced understanding of the pathology, and increased interest in assessment of disease severity are the cornerstones of future management strategies of this complex and heterogeneous disease in the 21st century. | Alfredo F Tonsi Matilde Bacchion Stefano Crippa Giuseppe Malleo Claudio Bassi | 2009 | World Journal of Gastroenterology2009,15,24: | 54 |
| 2 | Gut microbiota role in irritable bowel syndrome:Newtherapeutic strategies显示文摘In the last decade the impressive expansion of our knowledge of the vast microbial community that resides in the human intestine, the gut microbiota, has provided support to the concept that a disturbed intestinal ecology might promote development and maintenance of symptoms in irritable bowel syndrome(IBS). As a correlate, manipulation of gut microbiota represents a new strategy for the treatment of this multifactorial disease. A number of attempts have been made to modulate the gut bacterial composition, following the idea that expansion of bacterial species considered as beneficial(Lactobacilli and Bifidobacteria) associated with the reduction of those considered harmful(Clostridium, Escherichia coli, Salmonella, Shigella and Pseudomonas) should attenuate IBS symptoms. In this conceptual framework, probiotics appear an attractive option in terms of both efficacy and safety, while prebiotics, synbiotics and antibiotics still need confirmation. Fecal transplant is an old treatment translated from the cure of intestinal infective pathologies that has recently gained a new life as therapeutic option for those patients with a disturbed gut ecosystem, but data on IBS are scanty and randomized, placebo-controlled studies are required. | Eleonora Distrutti Lorenzo Monaldi Patrizia Ricci Stefano Fiorucci | 2016 | World Journal of Gastroenterology2016,22,7: | 60 |
| 3 | Role of microRNAs in translation regulation and cancer显示文摘MicroRNAs(miRNAs) are pervasively expressed and regulate most biological functions. They function by modulating transcriptional and translational programs and therefore they orchestrate both physiological and pathological processes, such as development, cell differentiation, proliferation, apoptosis and tumor growth. miRNAs work as small guide molecules in RNA silencing, by negatively regulating the expression of several genes both at mRNA and protein level, by degrading their mRNA target and/or by silencing translation. One of the most recent advances in the field is the comprehension of their role in oncogenesis. The number of miRNA genes is increasing and an alteration in the level of miRNAs is involved in the initiation, progression and metastases formation of several tumors. Some tumor types show a distinct miRNA signature that distinguishes them from normal tissues and from other cancer types. Genetic and biochemical evidence supports the essential role of miRNAs in tumor development. Although the abnormal expression of miRNAs in cancer cells is a widely accepted phenomenon, the cause of this dysregulation is still unknown. Here, we discuss the biogenesis of miRNAs, focusing on the mechanisms by which they regulate protein synthesis. In addition we debate on their role in cancer, highlighting their potential to become therapeutic targets. | Stefania Oliveto Marilena Mancino Nicola Manfrini Stefano Biffo | 2017 | World Journal of Biological Chemistry2017,8,1: | 60 |
| 4 | Risk of cardiovascular,cardiac and arrhythmic complications in patients with non-alcoholic fatty liver disease显示文摘Non-alcoholic fatty liver disease(NAFLD)has emerged as a public health problem of epidemic proportions worldwide.Accumulating clinical and epidemiological evidence indicates that NAFLD is not only associated with liver-related morbidity and mortality but also with an increased risk of coronary heart disease(CHD),abnormalities of cardiac function and structure(e.g.,left ventricular dysfunction and hypertrophy,and heart failure),valvular heart disease(e.g.,aortic valve sclerosis)and arrhythmias(e.g.,atrial fibrillation).Experimental evidence suggests that NAFLD itself,especially in its more severe forms,exacerbates systemic/hepatic insulin resistance,causes atherogenic dyslipidemia,and releases a variety of pro-inflammatory,pro-coagulant and pro-fibrogenic mediators that may play important roles in the pathophysiology of cardiac and arrhythmic complications.Collectively,these findings suggest that patients with NAFLD may benefit from more intensive surveillance and early treatment interventions to decrease the risk for CHD and other cardiac/arrhythmic complications.The purpose of this clinical review is to summarize the rapidly expanding body of evidence that supports a strong association between NAFLD and cardiovascular,cardiac and arrhythmic complications,to briefly examine the putative biological mechanisms underlying this association,and to discuss some of the current treatment options that may influence both NAFLD and its related cardiac and arrhythmic complications. | Stefano Ballestri Amedeo Lonardo Stefano Bonapace Christopher D Byrne Paola Loria Giovanni Targher | 2014 | World Journal of Gastroenterology2014,20,7: | 55 |
| 5 | Worldwide epidemiology of liver hydatidosis including the Mediterranean area显示文摘The worldwide incidence and prevalence of cystic echinococcosis have fallen dramatically over the past several decades.Nonetheless,infection with Echinococcus granulosus(E.granulosus)remains a major public health issue in several countries and regions,even in places where it was previously at low levels,as a result of a reduction of control programmes due to economic problems and lack of resources.Geographic distribution differs by country and region depending on the presence in that country of large numbers of nomadic or semi-nomadic sheep and goat flocks that represent the intermediate host of the parasite,and their close contact with the final host,the dog,which mostly provides the transmission of infection to humans.The greatest prevalence of cystic echinococcosis in human and animal hosts is found in countries of the temperate zones,including several parts of Eurasia(the Mediterranean regions,southern and central parts of Russia,central Asia,China),Australia,some parts of America(especially South America)and north and east Africa.Echinococcosis is currently considered an endemic zoonotic disease in the Mediterranean region.The most frequent strain associated with human cystic echinococcosis appears to be the common sheep strain(G1).This strain appears to be widely distributed in all continents.The purpose of this review is to examine the distribution of E.granulosus and the epidemiology of a re-emerging disease such as cystic echinococcosis. | Giuseppe Grosso Salvatore Gruttadauria Antonio Biondi Stefano Marventano Antonio Mistretta | 2012 | World Journal of Gastroenterology2012,18,13: | 36 |

| 7 | Hepatocellular carcinoma in nonalcoholic fatty liver: Role of environmental and genetic factors显示文摘Hepatocellular carcinoma(HCC) is the fourth cause of cancer related mortality, and its incidence is rapidly increasing. Viral hepatitis, alcohol abuse, and exposure to hepatotoxins are major risk factors, but nonalcoholic fatty liver disease(NAFLD) associated with obesity, insulin resistance, and type 2 diabetes, is an increasingly recognized trigger, especially in developed countries. Older age, severity of insulin resistance and diabetes, and iron overload have been reported to predispose to HCC in this context. Remarkably, HCCs have been reported in non-cirrhotic livers in a higher proportion of cases in NAFLD patients than in other etiologies. Inherited factors have also been implicated to explain the different individual susceptibility to develop HCC, and their role seems magnified in fatty liver, where only a minority of affected subjects progresses to cancer. In particular, the common I148 M variant of the PNPLA3 gene influencing hepatic lipid metabolism influences HCC risk independently of its effect on the progression of liver fibrosis. Recently, rare loss-of-function mutations in Apolipoprotein B resulting in very low density lipoproteins hepatic retention and in Telomerase reverse transcriptase influencing cellular senescence have also been linked to HCC in NAFLD. Indeed, hepatic stellate cells senescence has been suggested to bridge tissue aging with alterations of the intestinal microbiota in the pathogenesis of obesity-related HCC. A deeper understanding of the mechanisms mediating hepatic carcinogenesis during insulin resistance, and the identification of its genetic determinants will hopefully provide new diagnostic and therapeutic tools. | Paola Dongiovanni Stefano Romeo Luca Valenti | 2014 | World Journal of Gastroenterology2014,20,36: | 38 |
| 8 | 流化床内颗粒流体两相流的CFD模拟显示文摘采用先进的CFD模拟技术分析流化床内两相复杂体系的非线性流体动力学特征已得到普遍认同,但是由于不同研究者对颗粒与颗粒以及颗粒与流体之间相互作用力认识的差异,导致欧拉-欧拉框架下动量守恒方程的不同表达形式。本文在总结文献中有关颗粒黏性力、固相压力和两相间作用力的基础上,从双流体理论出发,提出了一个考虑拟平衡态下固体颗粒对流体相和固相动量守恒方程均有影响的简捷流体动力学模型。该模型的主要特点是表征颗粒离散属性的特征长度视为颗粒直径的同一数量级。随后在CFX4.4商业化软件平台上通过增加用户自定义子程序,对网格尺度、时间步长和最大颗粒堆积率的无关性进行检验,介绍了作者近年来采用该模型模拟二维/三维流化床内液固体系的散式流态化、气固GeldartA类物料的散式/聚式流态化和床层塌落特性以及GeldartB/D类物料的鼓泡/射流流态化和床层塌落的研究进展。模拟的主要结果与经典理论、本研究实验和文献报道数据相一致,说明该模型可以用来预测流化床内密相颗粒流体体系的动力学特性。 | 张锴 Brandani Stefano | 2010 | 化工学报2010,61,9: | 33 |

| 10 | Introducing an enhanced recovery after surgery program in colorectal surgery:A single center experience显示文摘AIM:To study the implementation of an enhanced recovery after surgery(ERAS)program at a large University Hospital from'pilot study'to'standard of care'.METHODS:The study was designed as a prospective single centre cohort study.A prospective evaluation of compliance to a protocol based on full application of all ERAS principles,through the progressive steps of its implementation,was performed.Results achieved in the initial pilot study conducted by a dedicated team(n=47)were compared to those achieved in the shared protocol phase(n=143)three years later.Outcomes were length of postoperative hospital stay,readmission rate,compliance to the protocol and morbidity.Primary endpoint was the description of the results and the identification of critical issues of large scale implementation of an ERAS program in colorectal surgery emerged in the experience of a single center.Secondary endpoint was the identification of interventions that have been proven to be effective for facilitating the transition from traditional care pathways to a multimodal management protocol according to ERAS principles in colorectal surgery at a single center.RESULTS:During the initial pilot study(March 2009 to December 2010;47 patients)conducted by a dedicated multidisciplinary team,compliance to the items of ERAS protocol was 93%,with a median length of hospital stay(LOS)of 3 d.Early anastomotic fistulas were observed in 2 cases(4.2%),which required reoperation(Clavien-Dindo gradeⅢb).None of the patients had been discharged before the onset of the complication,which could therefore receive prompt treatment.There were also four(8.5%)minor complications(ClavienDindo gradeⅡ).Thirty days readmission rate was 4%.Perioperative mortality was nil.After implementation of the protocol throughout the Hospital in unselected patients(May 2012 to December 2012;147 patients)compliance was 74%,with a median LOS of 6 d.Early anastomotic fistulas were observed in 11 cases(7.7%),5(3.5%)of which required reoperation(Clavien-Dindo gradeⅢb).Two early anastomotic fistulas were treated by radiologic/endoscopic manoeuvres and 4 were treated conservatively.There were also 36(25.2%)minor complications,21(14.7%)of which were Clavien-Dindo gradeⅡand 15(10.5%)of which were Clavien-Dindo gradeⅠ.Only two patients whose course was adversely affected by the development of an anastomotic leak had been discharged before the onset of the complication itself,requiring readmission.Readmission rate within 30 d was 4%.Perioperative mortality was 1%.CONCLUSION:Our results confirm that introduction of an ERAS protocol for colorectal surgery allows quickerpostoperative recovery and shortens the length of stay compared to historical series. | Stefano Bona Mattia Molteni Riccardo Rosati Ugo Elmore Pietro Bagnoli Roberta Monzani Monica Caravaca Marco Montorsi | 2014 | World Journal of Gastroenterology2014,20,46: | 30 |
| 11 | Coronary microvascular dysfunction in diabetes mellitus:A review显示文摘The exploration of coronary microcirculatory dysfunction in diabetes has accelerated in recent years.Cardiac function is compromised in diabetes.Diabetic patients manifest accelerated atherosclerosis in coronary arteries.These data are confirmed in diabetic animal mod-els,where lesions of small coronary arteries have been described.These concepts are epitomized in the classic microvascular complications of diabetes,i.e.blindness,kidney failure and distal dry gangrene.Most importantly,accumulating data indicate that insights gained from the link between inflammation and diabetes can yield predictive and prognostic information of considerable clinical utility.This review summarizes the evidence for the predisposing factors and the mechanisms involved in diabetes,and assesses the current state of knowledge regarding the triggers for inflammation in this disease.We evaluate the roles of hyperglycemia,oxidative stress,polyol pathway,protein kinase C,advanced glycation end products,insulin resistance,peroxisome proliferator-activated receptor-γ,inflammation,and diabetic cardiomyopathy as a 'stem cell disease'.Furthermore,we discuss the mechanisms responsible for impaired coronary arteriole function.Finally,we consider how new insights in diabetes may provide innovative therapeutic strategies. | Andrea Picchi Stefano Capobianco Marta Focardi | 2010 | World Journal of Cardiology2010,2,11: | 24 |
| 12 | Extraintestinal manifestations in inflammatory bowel disease显示文摘Inflammatory bowel diseases (IBD) can be really considered to be systemic diseases since they are often associated with extraintestinal manifestations,complications, and other autoimmune disorders. Indeed,physicians who care for patients with ulcerative colitis and Crohn's disease, the two major forms of IBD, face a new clinical challenge every day, worsened by the very frequent rate of extraintestinal complications. The goal of this review is to provide an overview and an update on the extraintestinal complications occurring in IBD.Indeed, this paper highlights how virtually almost every organ system can be involved, principally eyes, skin,joints, kidneys, liver and biliary tracts, and vasculature (or vascular system) are the most common sites of systemic IBD and their involvement is dependent on different mechanisms. | Silvio Danese Stefano Semeraro Alfredo Papa Italia Roberto Franco Scaldaferri Giuseppe Fedeli Giovanni Gasbarrini Antonio Gasbarrini | 2005 | World Journal of Gastroenterology2005,11,46: | 24 |
| 13 | Low-volume plus ascorbic acid vs high-volume plus simethicone bowel preparation before colonoscopy显示文摘AIM:To investigate the effectiveness of low-volumeplus ascorbic acid [polyethylene glycol plus ascorbicacid(PEG + Asc) ] and high-volume plus simethicone[polyethylene glycol plus simethicone(PEG + Sim) ]bowel preparations.METHODS:A total of one hundred and forty-fourout patients(76 males) ,aged from 20 to 84 years(me-dian age 59.5 years) ,who attended our Department,were divided into two groups,age and sex matched,and underwent colonoscopy. Two questionnaires,onefor patients reporting acceptability and the other forendoscopists evaluating bowel cleansing effectivenes saccording to validated scales,were completed. Indications,timing of examination and endoscopical findings were recorded. Biopsy forceps were used as a measuring tool in order to determine polyp endoscopic sizeestimation. Difficulty in completing the preparation wasrated in a 5-point Likert scale(1 = easy to 5 = un-able) . Adverse experiences(fullness,cramps,nausea,vomiting,ab dominal pain,headache and insomnia) ,number of evacuations and types of activities performed during preparation(walking or resting in bed) were also investigated.RESULTS:Seventy-two patients were selected for eachgroup. The two groups were age and sex matched aswell as being comparable in terms of medical historyand drug therapies taken. Fourteen patients droppedout from the trial because they did not complete the preparation procedure. Ratings of global bowel cleansing examinations were considered to be adequate in91% of PEG + Asc and 88% of PEG + Sim patients.Residual Stool Score indicated similar levels of amountand consistency of residual stool;there was a significant difference in the percentage of bowel wall visuali-zation in favour of PEG + Sim patients. In the PEG +Sim group,12 adenomas ≤ 10 mm diameter(5/left co-lon + 7/right colon) vs 9(8/left colon + 1/right colon) in the PEG + Asc group were diagnosed. Visualization of small lesions seems to be one of the primary advantages of the PEG + Sim preparation.CONCLUSION:PEG + Asc is a good alternative solution as a bowel preparation but more improvements arenecessary in order to achieve the target of a perfect preparation. | Stefano Pontone Rita Angelini Monica Standoli Gregorio Patrizi Franco Culasso Paolo Pontone Adriano Redler | 2011 | World Journal of Gastroenterology2011,17,42: | 22 |
| 14 | Downstaging disease in patients with hepatocellular carcinoma outside up-to-seven criteria: Strategies using degradable starch microspheres transcatheter arterial chemo-embolization显示文摘AIM: To evaluate the downstaging rates in hepatitis C virus-patients with hepatocellular carcinoma(HCC), treated with degradable starch microspheres transcatheter arterial chemoembolization(DSM-TACE), to reach new-Milan-criteria(nM C) for transplantation. METHODS: This study was approved by the Ethics Committee of our institution. From September 2013 to March 2014 eight patients(5 men and 3 women) with liver cirrhosis and multinodular HCC, that did not meet n MC at baseline, were enrolled in this study. Patients who received any other type of treatment such as termal ablation or percutaneous ethanol injection were excluded. DSM-TACE was performed in all patients using Embo Cept? S and doxorubicin. Baseline and follow-up computed tomography or magnetic resonance imaging was assessed measuring the longest enhancing axial dimension of each tumor according to the modified Response Evaluation Criteria In Solid Tumors measure-ments, and medical records were reviewed.RESULTS: DSM-TACE was successfully performed in all patients without major complication. We treated 35 lesions(mean 4.3 per patient). Six of eight patients(75%) had their HCC downstaged to meet nM C. Every patient whose disease was downstaged eventually underwent transplantation. The six patients who received transplant were still living at the time of this writing, without recurrence of HCC. Baseline age(P = 0.25), Model for End-stage Liver Disease score(P = 0. 77), and α-fetoprotein level(P = 1.00) were similar between patients with and without downstaged HCC. CONCLUSION: DSM-TACE represents a safely and effective treatment option with similar safety and efficacy of conventional chemoembolization and could be successfully performed also for downstaging disease in patients without n MC, allowing them to reach liver transplantation. | Antonio Orlacchio Fabrizio Chegai Stefano Merolla Simona Francioso Costantino Del Giudice Mario Angelico Giuseppe Tisone Giovanni Simonetti | 2015 | World Journal of Hepatology2015,7,12: | 23 |
| 15 | Gut microbiota in autism and mood disorders显示文摘The hypothesis of an important role of gut microbiota in the maintenance of physiological state into the gastrointestinal(GI)system is supported by several studies that have shown a qualitative and quantitative alteration of the intestinal flora in a number of gastrointestinal and extra-gastrointestinal diseases.In the last few years,the importance of gut microbiota impairment in the etiopathogenesis of pathology such as autism,dementia and mood disorder,has been raised.The evidence of the inflammatory state alteration,highlighted in disorders such as schizophrenia,major depressive disorder and bipolar disorder,strongly recalls the microbiota alteration,highly suggesting an important role of the alteration of GI system also in neuropsychiatric disorders.Up to now,available evidences display that the impairment of gut microbiota plays a key role in the development of autism and mood disorders.The application of therapeutic modulators of gut microbiota to autism and mood disorders has been experienced only in experimental settings to date,with few but promising results.A deeper assessment of the role of gut microbiota in the development of autism spectrum disorder(ASD),as well as the advancement of the therapeutic armamentarium for the modulation of gut microbiota is warranted for a better management of ASD and mood disorders. | Francesca Mangiola Gianluca Ianiro Francesco Franceschi Stefano Fagiuoli Giovanni Gasbarrini Antonio Gasbarrini | 2016 | World Journal of Gastroenterology2016,22,1: | 23 |
| 16 | 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 |
| 17 | Total mesorectal excision for mid and low rectal cancer: laparoscopic vs robotic surgery显示文摘AIM: To compare the short- and long-term outcomes of laparoscopic and robotic surgery for middle and low rectal cancer.METHODS: This is a retrospective study on a prospectively collected database containing 111 patients who underwent minimally invasive rectal resection with total mesorectal excision(TME) with curative intent between January 2008 and December 2014(robot, n = 53; laparoscopy, n = 58). The patients all had a diagnosis of middle and low rectal adenocarcinoma with stage?Ⅰ-Ⅲ disease. The median follow-up period was 37.4 mo. Perioperative results, morbidity a pathological data were evaluated and compared. The 3-year overall survival and disease-free survival rates were calculated and compared.RESULTS: Patients were comparable in terms of preoperative and demographic parameters. The median surgery time was 192 min for laparoscopic TME(L-TME) and 342 min for robotic TME(R-TME)(P < 0.001). There were no differences found in the rates of conversion to open surgery and morbidity. Thepatients who underwent laparoscopic surgery stayed in the hospital two days longer than the robotic group patients(8 d for L-TME and 6 d for R-TME, P < 0.001). The pathologic evaluation showed a higher number of harvested lymph nodes in the robotic group(18 for R-TME, 11 for L-TME, P < 0.001) and a shorter distal resection margin for laparoscopic patients(1.5 cm for L-TME, 2.5 cm for R-TME, P < 0.001). The three-year overall survival and disease-free survival rates were similar between groups.CONCLUSION: Both L-TME and R-TME achieved acceptable clinical and oncologic outcomes. The robotic technique showed some advantages in rectal surgery that should be validated by further studies. | Francesco Feroci Andrea Vannucchi Paolo Pietro Bianchi Stefano Cantafio Alessia Garzi Giampaolo Formisano Marco Scatizzi | 2016 | World Journal of Gastroenterology2016,22,13: | 22 |
| 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 |

| 20 | Climate and litter C/N ratio constrain soil organic carbon accumulation显示文摘Soil organic carbon(SOC) plays critical roles in stabilizing atmospheric CO2 concentration, but the mechanistic controls on the amount and distribution of SOC on global scales are not well understood. In turn, this has hampered the ability to model global C budgets and to find measures to mitigate climate change. Here, based on the data from a large field survey campaign with 2600 plots across China’s forest ecosystems and a global collection of published data from forested land, we find that a low litter carbon-to-nitrogen ratio(C/N) and high wetness index(P/PET, precipitation-to-potentialevapotranspiration ratio) are the two factors that promote SOC accumulation, with only minor contributions of litter quantity and soil texture. The field survey data demonstrated that high plant diversity decreased litter C/N and thus indirectly promoted SOC accumulation by increasing the litter quality. We conclude that any changes in plant-community composition, plant-species richness and environmental factors that can reduce the litter C/N ratio, or climatic changes that increase wetness index, may promote SOC accumulation. The study provides a guideline for modeling the carbon cycle of various ecosystem scales and formulates the principle for land-based actions for mitigating the rising atmospheric CO2 concentration. | Guoyi Zhou Shan Xu Philippe Ciais Stefano Manzoni Jingyun Fang Guirui Yu Xuli Tang Ping Zhou Wantong Wang Junhua Yan Gengxu Wang Keping Ma Shenggong Li Sheng Du Shijie Han Youxin Ma Deqiang Zhang Juxiu Liu Shizhong Liu Guowei Chu Qianmei Zhang Yuelin Li Wenjuan Huang Hai Ren Xiankai Lu Xiuzhi Chen | 2019 | National Science Review2019,6,4: | 21 |
