| 2 | Adhesive small bowel adhesions obstruction: Evolutions in diagnosis, management and prevention显示文摘Intra-abdominal adhesions following abdominal surgery represent a major unsolved problem. They are the first cause of small bowel obstruction. Diagnosis is based on clinical evaluation, water-soluble contrast followthrough and computed tomography scan. For patients presenting no signs of strangulation, peritonitis or severe intestinal impairment there is good evidence to support non-operative management. Open surgery is the preferred method for the surgical treatment of adhesive small bowel obstruction, in case of suspected strangulation or after failed conservative management, but laparoscopy is gaining widespread acceptance especially in selected group of patients. 'Good' surgical technique and anti-adhesive barriers are the main current concepts of adhesion prevention. We discuss current knowledge in modern diagnosis and evolving strategies for management and prevention that are leading to stratified care for patients. | Fausto Catena Salomone Di Saverio Federico Coccolini Luca Ansaloni Belinda De Simone Massimo Sartelli Harry Van Goor | 2016 | World Journal of Gastrointestinal Surgery2016，8，3： | 28 |
| 3 | Advanced gastric cancer:what we know and what we stillhave to learn显示文摘Gastric cancer is a common neoplastic disease and, more precisely, is the third leading cause of cancer death in the world, with differences amongst geographic areas. The definition of advanced gastric cancer is still debated. Different stadiating systems lead to slightly different stadiation of the disease, thus leading to variations between the single countries in the treatment and outcomes. In the present review all the possibilities of treatment for advanced gastric cancer have been analyzed. Surgery, the cornerstone of treatment for advanced gastric cancer, is analyzed first, followed by an investigation of the different forms and drugs of chemotherapy and radiotherapy. New frontiers in treatment suggest the growing consideration for intraperitoneal administration of chemotherapeutics and combination of traditional drugs with new ones. Moreover, the necessity to prevent the relapse of the disease leads to the consideration of administering intraperitoneal chemotherapy earlier in the therapeutical algorithm. | Federico Coccolini Giulia Montori Marco Ceresoli Simona Cima Maria Carla Valli Gabriela E Nita Arianna Heyer Fausto Catena Luca Ansaloni | 2016 | World Journal of Gastroenterology2016，22，3： | 25 |
| 4 | Systemic inflammation and immune response after laparotomy vs laparoscopy in patients with acute cholecystitis, complicated by peritonitis显示文摘AIM: To evaluate acute cholecystitis, complicated by peritonitis, acute phase response and immunological status in patients treated by laparoscopic or open approach. METHODS: From January 2002 to May 2012, we conducted a prospective randomized study on 45 consecutive patients (27 women, 18 men; mean age 58 years). These subjects were taken from a total of 681 patients who were hospitalised presenting similar preoperative findings: acute upper abdominal pain with tenderness, involuntary guarding under the right hypochondrium and/or in the flank; fever higher than 38 ℃, leukocytosis greater than 10 × 10 9 /L or both, and ultrasonographic evidence of calculous cholecystitis possibly complicated by peritonitis. These patients had undergone cholecystectomy for acute calculous cholecystitis,complicated by bile peritonitis. Randomly, 23 patients were assigned to laparoscopic cholecystectomy (LC), and 22 patients to open cholecystectomy (OC). Blood samples were collected from all patients before operation and at days 1, 3 and 6 after surgery. Serum bacteraemia, endotoxaemia, white blood cells (WBCs), WBC subpopulations, human leukocyte antigen-DR (HLA-DR), neutrophil elastase, interleukin-1 (IL-1) and IL-6, and C-reactive protein (CRP) were measured at 0, 30, 60, 90, 120 and 180 min, at 4, 6, 12, 24 h, and then daily (8 A.M.) until post-operative day 6.RESULTS: The two groups were comparable in the severity of peritoneal contamination as indicated by the viable bacterial count (open group = 90% of positive cultures vs laparoscopic group = 87%) and endotoxin level (open group = 33.21 ± 6.32 pg/mL vs laparoscopic group = 35.02 ± 7.23 pg/mL). Four subjects in the OC group (18.1%) and 1 subject (4.3%) in the LC group (P < 0.05) developed intra-abdominal abscess. Severe leukocytosis (range 15.8-19.6/mL) was observed only after OC but not after LC, mostly due to an increase in neutrophils (days 1 and 3, P < 0.05). This value returned to the normal range within 3-4 d after LC and 5-7 d after OC. Other WBC types and lymphocyte subpopulations showed no significant variation. On the first day after surgery, a statistically significant difference was observed in HLA-DR expression between LC (13.0 ± 5.2) and OC (6.0 ± 4.2) (P < 0.05). A statistically significant change in plasma elastase concentration was recorded post-operatively at days 1, 3, and 6 in patients from the OC group when compared to the LC group (P < 0.05). In the OC group, the serum levels of IL-1 and IL-6 began to increase considerably from the first to the sixth hour after surgery. In the LC group, the increase of serum IL-1 and IL-6 levels was delayed and the peak values were notably lower than those in the OC group. Significant differences between the groups, for these two cytokines, were observed from the second to the twenty-fourth hour (P < 0.05) after surgery. The mean values of serum CRP in the LC group on post-operative days (1 and 3) were also lower than those in the OC group (P < 0.05). Systemic concentration of endotoxin was higher in the OC group at all intra-operative sampling times, but reached significance only when the gallbladder was removed (OC group = 36.81 ± 6.4 ρg/mLvs LC group = 16.74 ± 4.1 ρg/mL, P < 0.05). One hour after surgery, microbiological analysis of blood cultures detected 7 different bacterial species after laparotomy, and 4 species after laparoscopy (P < 0.05). CONCLUSION: OC increased the incidence of bacteraemia, endotoxaemia and systemic inflammation compared with LC and caused lower transient immunological defense, leading to enhanced sepsis in the patients examined. | Federico Sista Mario Schietroma Giuseppe De Santis Antonella Mattei Emanuela Marina Cecilia Federica Piccione Sergio Leardi Francesco Carlei Gianfranco Amicucci | 2013 | World Journal of Gastrointestinal Surgery2013，5，4： | 23 |
| 5 | Efficacy of rituximab in gastric diffuse large B cell lymphoma patients显示文摘AIM:To evaluate retrospectively the efficacy of rituximab plus chemotherapy in gastric diffuse large B cell lymphoma(DLBCL).METHODS:Sixty patients(median age:58 years)with histologically confirmed gastric DLBCL treated at four Italian institutions between 2000 and 2007,were included in this analysis.Patients were selected by stage (Ⅰ-Ⅳ,Lugano staging system),European Cooperative Oncology Group performance status(0-2)and treatment strategies.Treatment strategies were chemotherapy alone(group A,n=30)[scheduled as cyclophosphamide,doxorubicin,vincristine and prednisone (CHOP)and CHOP-like],and chemotherapy combined with rituximab(group B,n=30).The primary end point of the study was complete response(CR)rate;the secondary end points were disease-free survival (DFS)at 5 years and overall survival(OS).RESULTS:Median follow-up was 62 mo(range:31102 mo).We observed a significant difference between the two groups(A vs B)in terms of CR[76.6%(23/30) vs 100%,P=0.04)and DFS at 5 years[73.3%(22/30) vs 100%,P=0.03).To date,19 group A(63.3%) patients are alive and 11 have died,while all group B patients are alive.No significant differences in toxicity were observed between the two groups.CONCLUSION:Rituximab in combination with chemotherapy improves CR rate,DFS and OS.Further prospective trials are needed to confirm our results. | Davide Leopardo Giuseppe Di Lorenzo Amalia De Renzo Piera Federico Serena Luponio Carlo Buonerba Elide Matano Gerardina Merola Martina Imbimbo Enzo Montesarchio Antonio Rea Maria Carmela Merola Sabino De Placido Giovannella Palmieri | 2010 | World Journal of Gastroenterology2010，16，20： | 19 |
| 6 | Potential pathophysiological role for the vitamin D deficiency in essential hypertension显示文摘Vitamin D deficiency has been indicated as a pandemicemerging public health problem. In addition to the well-known role on calcium-phosphorus homeostasis in thebone, vitamin D-mediated processes have been recentlyinvestigated on other diseases, such as infections, can-cer and cardiovascular diseases. Recently, both the dis-covery of paracrine actions of vitamin D(recognized as'local vitamin D system') and the link of vitamin D with renin-angiotensin-aldosterone system and the fibroblast growth factor 23/klotho pathways highlighted its ac-tive cardiovascular activity. Focusing on hypertension, this review summarizes the more recent experimental evidence involving the vitamin D system and deficiency in the cardiovascular pathophysiology. In particular, we updated the vascular synthesis/catabolism of vitamin D and its complex interactions between the various endocrine networks involved in the regulation of blood pressure in humans. On the other hand, the conflicting results emerged from the comparison between obser-vational and interventional studies emphasize the frag-mentary nature of our knowledge in the field of vitamin D and hypertension, strongly suggesting the need of further researches in this field. | Federico Carbone Fran?ois Mach Nicolas Vuilleumier Fabrizio Montecucco | 2014 | World Journal of Cardiology2014，6，5： | 17 |

| 8 | Silymarin in non alcoholic fatty liver disease显示文摘AIM: This study was undertaken to evaluate the hepatic effects of silybum marianum on non alcoholic fatty liver disease (NAFLD). METHODS: In 72 patients affected by NAFLD, main metabolic, hepatic and anti-inflammatory parameters were assayed after 3 mo of a restricted diet and before silymarin treatment (twice a day orally). The brightness of liver echography texture (hepatorenal ratio brightness) was also defined at same time. These evaluations were repeated after 6 mo of treatment. RESULTS: Serum levels of some metabolic and anti-inflammatory data nonsignificantly lowered after 6 mo of silymarin. On the contrary, Steato test, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transpeptidase were significantly (P < 0.001) reduced. Instead, the AST/ALT ratio unchanged. Finally, the hepatorenal brightness ratio, as an index of hepatic steatosis, significantly (P < 0.05) dropped. CONCLUSION: The obtained results indicate that silymarin appears to be effective to reduce the biochemical, inflammatory and ultrasonic indices of hepatic steatosis. Some parameters indicative of early stage of atherosclerosis were also lowered. | Fulvio Cacciapuoti Anna Scognamiglio Rossella Palumbo Raffaele Forte Federico Cacciapuoti | 2013 | World Journal of Hepatology2013，5，3： | 17 |

| 10 | Acute appendicitis: Epidemiology, treatment and outcomesanalysis of 16544 consecutive cases显示文摘AIM To investigate the epidemiology,treatment and outcomes of acute appendicitis(AA) in a large population study.METHODS This is a retrospective cohort study derived from the administrative dataset of the Bergamo district healthcare system(more than 1 million inhabitants) from 1997 to 2013.Data about treatment,surgery,length of stay were collected.Moreover for each patients were registered data about relapse of appendicitis and hospital admission due to intestinal obstruction.RESULTS From 1997 to 2013 in the Bergamo district we collected 16544 cases of AA,with a crude incidence rate of 89/100000 inhabitants per year; mean age was 24.51 ± 16.17,54.7% were male and the mean Charlson's comorbidity index was 0.32 ± 0.92.Mortality was < 0.0001%.Appendectomy was performed in 94.7% of the patients and the mean length of stay was 5.08 ± 2.88 d; the cumulative hospital stay was 5.19 ± 3.36 d and 1.2% of patients had at least one further hospitalization due intestinal occlusion.Laparoscopic appendectomy was performed in 48% of cases.Percent of 5.34 the patients were treated conservatively with a mean length of stay of 3.98 ± 3.96 d; the relapse rate was 23.1% and the cumulative hospital stay during the study period was 5.46 ± 6.05 d.CONCLUSION The treatment of acute appendicitis in Northern Italy is slowly changing,with the large diffusion of laparoscopic approach; conservative treatment of non-complicated appendicitis is still a neglected option,but rich of promising results. | Marco Ceresoli Alberto Zucchi Niccolò Allievi Asaf Harbi Michele Pisano Giulia Montori Arianna Heyer Gabriela E Nita Luca Ansaloni Federico Coccolini | 2016 | World Journal of Gastrointestinal Surgery2016，8，10： | 14 |
| 11 | Far lateral lumbar disc herniation part 1: Imaging, neurophysiology and clinical features显示文摘Far lateral lumbar disc herniations(FLLDH)represent a separate category of disc pathology which includes both intraforaminal and extraforaminal lumbar disc herniations,that are characterized by a peculiar clinical presentation,diagnostic and treatment modalities as compared to the more frequent median and paramedian disc hernias.Surgical treatment often represents the only effective weapon for the cure of this disease and over the years different approaches have been developed that can reach the region of the foramen or external to it,with different degrees of invasiveness.The diagnosis is more demanding and still underestimated as it requires a more detailed knowledge in the spine anatomy and dedicated radiological studies.Computerized tomography and in particular magnetic resonance imaging are the appropriate tools for the diagnosis of FLLDH.Despite the widespread use of these diagnostic tests,many cases of FLLDH are overlooked due to insufficiently detailed radiological examinations or due to the execution of exams not focused to the foraminal or the extraforaminal region.Neurophysiological studies represent a valid aid in the diagnostic classification of this pathology and in some cases they can facilitate the differential diagnosis with other types of radiculopathies.In the present study,a comprehensive review of the clinical presentation,epidemiology,radiological study and the neurophysiological aspects is presented. | Luigi Valentino Berra Andrea Di Rita Federico Longhitano Enrico Mailland Paolo Reganati Alessandro Frati Antonio Santoro | 2021 | World Journal of Orthopedics2021，12，12： | 14 |
| 12 | Fat:A matter of disturbance for the immune system显示文摘Obesity is increasingly being recognized as a risk factor for a number of benign and malignant gastrointestinal conditions. However, literature on the underlying pathophysiological mechanisms is sparse and ambiguous. There is compelling evidence that both overnutrition and undernutrition negatively interfere with the immune system. Overnutrition has been found to increase susceptibility to the development of inflammatory diseases, autoimmune diseases and cancer. In the regulation of immune and in? ammatory processes, white adipose tissue plays a critical role, not only as an energy store but also as an important endocrine organ. The obese state is characterised by a low-grade systemic in? ammation, mainly as a result of increased adipocytes as well as fat resident-and recruited-macrophage activity. In the past few years, various products of adipose tissue including adipokines and cytokines have been characterised and a number of pathways linking adipose tissue metabolism with the immune system have been identified. Activation of the innate immune system plays a major role in hepatic steatosis. Non-alcoholic fatty liver disease includes a wide spectrum of diseases, from pure steatosis to non-alcoholic steato-hepatitis in the absence of signif icant alcohol consumption. Although steatosis is considered a non-progressive disease, non-alcoholic steatohepatitis may deteriorate in advanced chronic liver diseases, cirrhosis, and hepatocellular carcinoma. An important parallel between obesityrelated pathology of adipose tissue and liver pertains to the emerging role of macrophages, and growing evidence suggests that Kupffer cells critically contribute to progression of non-alcoholic fatty liver disease. Moreover, a close link between specif ic immune activation and atherosclerosis has been well established, suggesting that fat can directly trigger immune responses. This review discusses the role of fat as 'a matter of disturbance for the immune system' with a focus on hepatic steatosis. | Alessandro Federico Elena D’Aiuto Francesco Borriello Giusi Barra Antonietta Gerarda Gravina Marco Romano Raffaele De Palma | 2010 | World Journal of Gastroenterology2010，16，38： | 12 |
| 13 | Doxorubicin-eluting bead vs conventional transcatheter arterial chemoembolization for hepatocellular carcinoma before liver transplantation显示文摘AIM:To assess the possible effect of two different types of preoperative transcatheter arterial chemoembolization(TACE)on recurrence-free survival after liver transplantation(LT)in patients with hepatocellular carcinoma(HCC)and to analyze the effects of TACE on tumor histology.METHODS:We retrospectively analyzed the histological features of 130 HCC nodules in 63 native livers removed at transplantation.Patients who received any other type of treatment such as radiofrequency tumor ablation,percutaneous ethanol ablation or who were not treated at all were excluded.All patients in the present study were within the Milan Criteria at the last imaging findings before transplantation.Doxorubicineluting bead TACE(DEB-TACE)was performed in 22patients(38 nodules),and conventional TACE(c-TACE)in 16(25 nodules).Patients’and tumors’characteristics were retrospectively reviewed.We performed a pernodule analysis of the explanted livers to establish the mean percentage of necrosis of any nodule treated by TACE(conventional or DEB)and a per-patient analysis to establish the percentage of necrosis in the cumulative tumor area,including 21 nodules not reached by TACE.Inflammatory and fibrotic changes in the tissue surrounding the tumor nodule were analyzed and categorized as poor/absent,moderate and enhanced reaction.Uni-and multivariate analysis of risk factors for HCC-recurrence were performed.RESULTS:The number and diameter of the nodules,the time spent on the waiting list and the number of treatments were similar in the two groups.A trend towards higher appropriate response rates(necrosis≥90%)was observed in the DEB-TACE group(44.7%vs32.0%,P=0.2834).The mean percentage of necrosis in the cumulative tumor area was 58.8%±36.6%in the DEB-TACE group and 50.2%±38.1%in the c-TACE group(P=0.4856).Fibrotic and inflammatory reactions surrounding the tumor nodule were markedly more common in the DEB-TACE group(P<0.0001,for both the parameters).The three-year recurrence-free survival was higher in DEB-TACE-treated patients than in conventionally treated patients(87.4%vs 61.5%,P=0.0493).Other factors affecting recurrence-free survival included viable tumor beyond Milan Criteria on histopathological examination,the percentage of necrosis on CTA≤50%and a pre-transplant serum-fetoprotein level greater than 70 ng/mL.On multivariate analysis,the lack of treatment with DEB-TACE,high levels of-fetoprotein and viable tumor beyond Milan Criteria at histology examination were identified as independent predictors of tumor recurrence.CONCLUSION:DEB-TACE can effectively promote tumor necrosis and improves recurrence-free survival after LT in HCC. | Daniele Nicolini Gianluca Svegliati-Baroni Roberto Candelari Cinzia Mincarelli Alessandra Mandolesi Italo Bearzi Federico Mocchegiani Andrea Vecchi Roberto Montalti Antonio Benedetti Andrea Risaliti Marco Vivarelli | 2013 | World Journal of Gastroenterology2013，19，34： | 12 |
| 14 | Normal and abnormal spine and thoracic cage development显示文摘Development of the spine and thoracic cage consists of a complex series of events involving multiple metabolic processes, genes and signaling pathways. During growth, complex phenomena occur in rapid succession. This succession of events, this establishment of elements, is programmed according to a hierarchy. These events are well synchronized to maintain harmonious limb, spine and thoracic cage relationships, as growth in the various body segments does not occur simultaneously at the same magnitude or rate. In most severe cases of untreated progressive earlyonset spinal deformities, respiratory insufficiency and pulmonary and cardiac hypertension(cor pulmonale), which characterize thoracic insufficiency syndrome(TIS), can develop, sometimes leading to death. TIS is the inability of the thorax to ensure normal breathing. This clinical condition can be linked to costo-vertebral malformations(e.g., fused ribs, hemivertebrae, congenital bars), neuromuscular diseases(e.g., expiratory congenital hypotonia), Jeune or Jarcho-Levin syndromes or to 50% to 75% fusion of the thoracic spine before seven years of age. Complex spinal deformities alter normal growth plate development, and vertebral bodies become progressively distorted, perpetuating the disorder. Therefore, many scoliotic deformities can become growth plate disorders over time. This review aims to provide a comprehensive review of how spinal deformities can affect normal spine and thoracic cage growth. Previous conceptualizations are integrated with more recent scientific data to provide a better understanding of both normal and abnormal spine and thoracic cage growth. | Federico Canavese Alain Dimeglio | 2013 | World Journal of Orthopedics2013，4，4： | 12 |
| 15 | Use of Voltage Limits for Current Limitations in Grid-forming Converters显示文摘Renewable generation interfaced through gridforming converters are proposed as a replacement for synchronous generators in power systems.However,compared to the synchronous generator,the power electronics converter has a strict limit on the current to avoid overcurrent damage.The gridforming converter acts like a voltage source,directily controlling the voltage.This conflicts with the operation of the conventional current limit control,which is applied to a current source.The switch between the voltage control and current control aimed to impose the current limit leads to synchronization instability.This paper proposes a novel control scheme which can be applied to the grid forming voltage control in order to enforce current limits.The proposed method has been verified through simulation and hardware tests in both symmetrical and asymmetrical faults to perform current suppression while maintaining synchronization stability in the voltage control mode. | Junru Chen Federico Prystupczuk Terence O’Donnell | 2020 | CSEE Journal of Power and Energy Systems2020，6，2： | 12 |
| 16 | 中国谷物醋的感官风味特征分析显示文摘为了分析中国谷物醋(Chinese cereal vinegars,CCV)的感官风味特征,收集了中国四大传统名醋产区山西、四川、福建和江苏的8个品牌,3种不同陈酿程度的食醋产品共24个,对它们的感官风味进行了分析和比较。结果表明,仅巧克力味、烘焙味、肉汤味等少数几种风味是这些CCV产品共有的,而其他一些风味,如胶水味、水果味和甘草味,为某些CCV产品所特有。研究还发现,陈酿对提升CCV的烘焙味和巧克力味起到了非常关键的作用,而原材料在某些产品风味,如甘草味的形成中可能起到了重要作用。 | GIUDICI Paolo 陈福生 杨浩然 盛峰 LEMMETTI Federico BONCIANI Tommaso MARASTONI Emanuele CORRADINI Giuseppe | 2017 | 中国酿造2017，36，9： | 11 |
| 17 | Role of MGMT as biomarker in colorectal cancer显示文摘O6-methylguanine DNA methyltransferase(MGMT) gene promoter methylation plays an important role in colorectal carcinogenesis, occurring in about 30%-40% of metastatic colorectal cancer. Its prognostic role has not been defined yet, but loss of expression of MGMT, which is secondary to gene promoter methylation, results in an interesting high response to alkylating agents such as dacarbazine and temozolomide. In a phase 2 study on heavily pre-treated patients with MGMT methylated metastatic colorectal cancer, temozolomide achieved about 30% of disease control rate. Activating mutations of RAS or BRAF genes as well as mismatch repair deficiency may represent mechanisms of resistance to alkylating agents, but a dose-dense schedule of temozolomide may potentially restore sensitivity in RAS-mutant patients. Further development of temozolomide in MGMT methylated colorectal cancer includes investigation of synergic combinations with other agents such as fluoropyrimidines and research for additional biomarkers, in order to better define the role of temozolomide in the treatment of individual patients. | Alessandro Inno Giuseppe Fanetti Maria Di Bartolomeo Stefania Gori Claudia Maggi Massimo Cirillo Roberto Iacovelli Federico Nichetti Antonia Martinetti Filippo de Braud Ilaria Bossi Filippo Pietrantonio | 2014 | World Journal of Clinical Cases2014，2，12： | 10 |
| 18 | Haplotype of prostaglandin synthase 2/cyclooxygenase 2 is involved in the susceptibility to inflammatory bowel disease显示文摘AIM: Prostaglandin G/H synthase 2 (PTGS2 or COX2) is one of the key factors in the cellular response to inflammation.PTGS2 is expressed in the affected intestinal segments of patients with inflammatory bowel diseases (IBD). In IBD patients, non-steroidal anti-inflammatory drugs, which have been shown to reduce both the production and activity of PTGS2, may activate IBD and aggravate the symptoms.We aimed at examining genetic variants of PTGS2 that may be risk factors for IBD.METHODS: We genotyped 291 individuals diagnosed with IBD and 367 controls from the Dutch population for the five most frequent polymorphisms of the PTGS2 gene.Clinical data were collected on all patients. DNA was extracted via normal laboratory methods. Genotyping was carried out using multiplex PCR followed by the Invader Assay and the 5' exonuclease assay (TaqMan). New polymorphism screening was performed by pre-screening with denaturing high-performance liquid chromatography,followed by fluorescent sequencing.RESULTS: Allele 5209G was weakly associated with Crohn's disease (odds ratio [OR] 1.63, 95% confidence interval [CI] 1.03-2.57), and allele 8473T with ulcerative colitis (OR 1.50, 95%CI 1.00-2.27). The haplotype including both alleles showed a strong association with IBD (OR 13.15, 95%CI 3.17-116.15). This haplotype, while rare (-0.3%) in the general population, is found more frequently in patients (3.5%).CONCLUSION: Our data suggest that this haplotype of PTGS2 contributes to the susceptibility of IBD. | David G Cox J Bart A Crusius Petra HM Peeters H Bas Bueno-de-Mesquita A Salvador Pe(n|~)a Federico Canzian | 2005 | World Journal of Gastroenterology2005，11，38： | 10 |
| 19 | Focus on emerging drugs for the treatment of patients with non-alcoholic fatty liver disease显示文摘Non-alcoholic fatty liver disease(NAFLD)has become the most common liver disorder in Western countries and is increasingly being recognized in developing nations.Fatty liver disease encompasses a spectrum of hepatic pathology,ranging from simple steatosis to non-alcoholic steatohepatitis,cirrhosis,hepatocellular carcinoma and end-stage liver disease.Moreover,NAFLD is often associated with other metabolic conditions,such as diabetes mellitus type 2,dyslipidemia and visceral obesity.The most recent guidelines suggest the management and treatment of patients with NAFLD considering both the liver disease and the associated metabolic co-morbidities.Diet and physical exercise are considered the first line of treatment for patients with NAFLD,but their results on therapeutic efficacy are often contrasting.Behavior therapy is necessary most of the time to achieve a sufficient result.Pharmacological therapy includes a wide variety of classes of molecules with different therapeutic targets and,often,little evidence supporting the real efficacy.Despite the abundance of clinical trials,NAFLD therapy remains a challenge for the scientific community,and there are no licensed therapies for NAFLD.Urgently,new pharmacological approaches are needed.Here,we will focus on the challenges facing actual therapeutic strategies and the most recent investigated molecules. | Alessandro Federico Claudio Zulli Ilario de Sio Anna Del Prete Marcello Dallio Mario Masarone Carmela Loguercio | 2014 | World Journal of Gastroenterology2014，20，45： | 10 |
| 20 | Over-the-scope clip closure of two chronic fistulas after gastric band penetration显示文摘Gastrointestinal perforations are conservatively managed at endoscopy by through-the-scope endoclips and covered self expandable stents, according to the size and tissue features of the perforation. This is believed to be the first report of successful closure of two gastrocutaneous fistulas with over-the-scope clips (OTSCs). After laparoscopic gastric banding, a 45-year old woman presented with band erosion and penetration. Despite surgical band removal and gastric wall suturing, external drainage of enteric material persisted for 2 wk, and esophagogastroduodenoscopy demonstrated two adjacent 10-mm and 15-mm fistulous orifices at the esophagogastric junction. After cauterization of the margins, the 10-mm fistulous tract was grasped by the OTSC anchor, invaginated into the applicator cap, and closed by a traumatic OTSC. The other 15-mm fistula was too large to be firmly grasped, and a fully-covered metal stent was temporarily placed. No leak occurred during the following 6 wk. At stent removal: the OTSC was completely embedded in hyperplastic overgrowth; the 15-mm fistula significantly reduced in diameter, and it was closed by another traumatic OTSC. After the procedure, no external fistula recurred and both OTSCs were lost spontaneously after 4 wk. The use of the anchor and the OTSC seem highly effective for successful closure of small chronic perforations. | Federico Iacopini Nicola Di Lorenzo Fabrizio Altorio Marc-Oliver Schurr Agostino Scozzarro | 2010 | World Journal of Gastroenterology2010，16，13： | 10 |
