| 1 | Laparoscopic natural orifice specimen extraction-colectomy: A systematic review显示文摘Over the last 20 years, laparoscopic colorectal surgery has shown equal efficacy for benign and malignant colorectal diseases when compared to open surgery. However, a laparoscopic approach reduces postoperative morbidity and shortens hospital stay. In the quest to optimize outcomes after laparoscopic colorectal surgery, reduction of access trauma could be a way to improve recovery. To date, one method to reduce access trauma is natural orifice specimen extraction(NOSE). NOSE aims to reduce access trauma in laparoscopic colorectal surgery. The specimen is delivered via a natural orifice and the anastomosis is created intracorporeally. Different methods are used to extract the specimen and to create a bowel anastomosis. Currently, specimens are delivered transcolonically, transrectally, transanally, or transvaginally. Each of these NOSEprocedures raises specific issues with regard to operative technique and application. The presumed benefits of NOSE-procedures are less pain, lower analgesia requirements, faster recovery, shorter hospital stay, better cosmetic results, and lower incisional hernia rates. Avoidance of extraction site laparotomy is the most important characteristic of NOSE. Concerns associated with the NOSE-technique include bacterial contamination of the peritoneal cavity, inflammatory response, and postoperative outcomes, including postoperative pain and the functional and oncologic outcomes. These issues need to be studied in prospective randomized controlled trials. The aim of this systematic review is to describe the role of NOSE in minimally invasive colorectal surgery. | Albert M Wolthuis Anthony de Buck van Overstraeten André D'Hoore | 2014 | World Journal of Gastroenterology2014，20，36： | 65 |

| 3 | Feasibility and safety of autologous bone marrow mononuclear cell transplantation in patients with advanced chronic liver disease显示文摘AIM: To evaluate the safety and feasibility of bone marrow cell (BMC) transplantation in patients with chronic liver disease on the waiting list for liver transplantation. METHODS: Ten patients (eight males) with chronic liver disease were enrolled to receive infusion of autologous bone marrow-derived cells. Seven patients were classified as Child-Pugh B and three as Child-Pugh C. Baseline assessment included complete clinical and laboratory evaluation and abdominal MRI. Approximately 50 ml of bone marrow aspirate was prepared by centrifugation in a ficoll-hypaque gradient. At least of 100 millions of mononuclear-enriched BMCs were infused into the hepatic artery using the routine technique for arterial chemoembolization for liver tumors. Patients were followed up for adverse events up to 4 mo. RESULTS: The median age of the patients was 52 years (range 24-70 years). All patients were discharged 48 h after BMC infusion. Two patients complained ofmild pain at the bone marrow needle puncture site. No other complications or specific side effects related to the procedure were observed. Bilirubin levels were lower at 1 (2.19 ± 0.9) and 4 mo (2.10 ± 1.0) after cell transplantation that baseline levels (2.78 ± 1.2). Albumin levels 4 mo after BMC infusion (3.73 ± 0.5) were higher than baseline levels (3.47 ± 0.5). International normalized ratio (INR) decreased from 1.48 (SD = 0.23) to 1.43 (SD = 0.23) one month after cell transplantation. CONCLUSION: BMC infusion into hepatic artery of patients with advanced chronic liver disease is safe and feasible. In addition, a decrease in mean serum bilirubin and INR levels and an increase in albumin levels are observed. Our data warrant further studies in order to evaluate the effect of BMC transplantation in patients with advanced chronic liver disease. | Andre Castro lyra Milena Botelho Pereira Soares luiz Flavio Maia da Silva Marcos Fraga Fortes André Goyanna Pinheiro Silva Augusto César de Andrade Mota Sheilla A Oliveira Eduardo lorens Braga Wilson Andrade de Carvalho Bernd Genser Ricardo Ribeiro dos Santos luiz Guilherme Costa lyra | 2007 | World Journal of Gastroenterology2007，13，7： | 21 |
| 4 | H pylori (CagA) and Epstein-Barr virus infection in gastric carcinomas:Correlation with p53 mutation and c-Myc,Bcl-2 and Bax expression显示文摘AIM: To investigate the interrelationship between H pylori and Epstein-Barr virus (EBV) infection in the gastric carcinogenesis having in focus the p53 mutation and the c-Myc, Bcl-2 and Bax expression. METHODS: seventy-one gastric carcinoma tissues were assessed by polymerase chain reaction (PCR) for H pylori and in situ hybridization for EBV. c-Myc, Bcl-2 and Bax expression were detected by immunohistochemistry and single-stranded conformational polymorphism (SSCP) for p53 mutation. RESULTS: The positivity rates for H pylori and EBV were 94.4% and 8.45%, respectively. The majority of the cases displayed only the H pylori presence. All EBV positive cases were also H pylori positive. None infectious agent was observed in 5.55% of the cases. The intestinal type tumor was more frequent in the co-infected and non-infected groups. The female predominated in the non-infected group showing statistical significance (70.4% vs 29.6%, P=0.039). The Bcl-2 was only detected in the group exclusively infected by H pylori. However, c-Myc and Bax were detected in the three groups but with a low frequency in the co-infected group. Mutation of p53 was present in all groups, with the highest frequencies in the H pylori positive groups. CONCLUSION: The frequency of H pylori infection in gastric carcinomas was high. The presented data indicated that gastric carcinogenesis has different pathways depending of the presence of the two investigated infectious agents, suggesting a possible involvement of H pylori with apoptotic process. The low expression of c-Myc and Bax in the EBV-positive groups suggests that EBV may inhibit the expression of these proteins. Nevertheless, p53 mutation shows to be a relevant alteration, independent of both infectious agents. | Valeska Portela Lima Marcos Antonio Pereira de Lima Angela Rosa André Márcia Valéria Pitombeira Ferreira Marcos Aurélio Pessoa Barros Sílvia Helena Barem Rabenhorst | 2008 | World Journal of Gastroenterology2008，14，6： | 17 |
| 5 | Challenges in the diagnosis and treatment of gestational trophoblastic neoplasia worldwide显示文摘Gestational trophoblastic neoplasia(GTN) is a rare tumor that originates from pregnancy that includes invasive mole, choriocarcinoma(CCA), placental site trophoblastic tumor and epithelioid trophoblastic tumor(PSTT/ETT). GTN presents different degrees of proliferation, invasion and dissemination, but, if treated in reference centers, has high cure rates, even in multi-metastatic cases.The diagnosis of GTN following a hydatidiform molar pregnancy is made according to the International Federation of Gynecology and Obstetrics(FIGO)2000 criteria: four or more plateaued human chorionic gonadotropin(hCG)concentrations over three weeks; rise in hCG for three consecutive weekly measurements over at least a period of 2 weeks or more; and an elevated but falling hCG concentrations six or more months after molar evacuation. However,the latter reason for treatment is no longer used by many centers. In addition,GTN is diagnosed with a pathological diagnosis of CCA or PSTT/ETT. For staging after a molar pregnancy, FIGO recommends pelvic-transvaginal Doppler ultrasound and chest X-ray. In cases of pulmonary metastases with more than 1cm, the screening should be complemented with chest computed tomography and brain magnetic resonance image. Single agent chemotherapy, usually Methotrexate(MTX) or Actinomycin-D(Act-D), can cure about 70% of patients with FIGO/World Health Organization(WHO) prognosis risk score ≤ 6(low risk), reserving multiple agent chemotherapy, such as EMA/CO(Etoposide,MTX, Act-D, Cyclophosphamide and Oncovin) for cases with FIGO/WHO prognosis risk score ≥ 7(high risk) that is often metastatic. Best overall cure rates for low and high risk disease is close to 100% and > 95%, respectively. The management of PSTT/ETT differs and cure rates tend to be a bit lower. The early diagnosis of this disease and the appropriate treatment avoid maternal death,allow the healing and maintenance of the reproductive potential of these women. | Antonio Braga Paulo Mora Andréia Cristina de Melo Angélica Nogueira-Rodrigues Joffre Amim-Junior Jorge Rezende-Filho Michael J Seckl | 2019 | World Journal of Clinical Oncology2019，10，2： | 15 |
| 6 | Endoscopy vs surgery in the treatment of early gastric cancer:Systematic review显示文摘AIM: To report a systematic review,establishing the available data to an unpublished 2a strength of evidence,better handling clinical practice.METHODS: A systematic review was performed using MEDLINE,EMBASE,Cochrane,LILACS,Scopus and CINAHL databases. Information of the selected studies was extracted on characteristics of trial participants,inclusion and exclusion criteria,interventions(mainly,mucosal resection and submucosal dissection vs surgical approach) and outcomes(adverse events,different survival rates,mortality,recurrence and complete resection rates). To ascertain the validity of eligible studies,the risk of bias was measured using the Newcastle-Ottawa Quality Assessment Scale. The analysis of the absolute risk of the outcomes was performed using the software Rev Man,by computingrisk differences(RD) of dichotomous variables. Data on RD and 95%CIs for each outcome were calculated using the Mantel-Haenszel test and inconsistency was qualified and reported in χ2 and the Higgins method(I2). Sensitivity analysis was performed when heterogeneity was higher than 50%,a subsequent assay was done and other findings were compiled.RESULTS: Eleven retrospective cohort studies were selected. The included records involved 2654 patients with early gastric cancer that filled the absolute or expanded indications for endoscopic resection. Threeyear survival data were available for six studies(n = 1197). There were no risk differences(RD) after endoscopic and surgical treatment(RD = 0.01,95%CI:-0.02-0.05,P = 0.51). Five-year survival data(n = 2310) showed no difference between the two groups(RD = 0.01,95%CI:-0.01-0.03,P = 0.46). Recurrence data were analized in five studies(1331 patients) and there was no difference between the approaches(RD = 0.01,95%CI:-0.00-0.02,P = 0.09). Adverse event data were identified in eight studies(n = 2439). A significant difference was detected(RD =-0.08,95%CI:-0.10--0.05,P < 0.05),demonstrating better results with endoscopy. Mortality data were obtained in four studies(n = 1107). There was no difference between the groups(RD =-0.01,95%CI:-0.02-0.00,P = 0.22).CONCLUSION: Three-,5-year survival,recurrence and mortality are similar for both groups. Considering complication,endoscopy is better and,analyzing complete resection data,it is worse than surgery. | André Kondo Eduardo Guimaraes Hourneaux de Moura Wanderley Marques Bernardo Osmar Kenji Yagi Diogo Turiani Hourneaux de Moura Eduardo Turiani Hourneaux de Moura José Gon?alves Pereira Bravo Kendi Yamazaki Paulo Sakai | 2015 | World Journal of Gastroenterology2015，21，46： | 12 |
| 7 | Role of mi RNAs and their potential to be useful as diagnostic and prognostic biomarkers in gastric cancer显示文摘Alterations in epigenetic control of gene expression play an important role in many diseases, including gastric cancer. Many studies have identified a large number of upregulated oncogenic mi RNAs and downregulated tumour-suppressor mi RNAs in this type of cancer. In this review, we provide an overview of the role of mi RNAs, pointing to their potential to be useful as diagnostic and/or prognostic biomarkers in gastric cancer. Moreover, we discuss the influence of polymorphisms and epigenetic modifications on mi RNA activity. | Kelly Cristina da Silva Oliveira Taíssa Maíra Thomaz Araújo Camila Inagaki Albuquerque Gabriela Alcantara Barata Carolina Oliveira Gigek Mariana Ferreira Leal Fernanda Wisnieski Fernando Augusto Rodrigues Mello Junior André Salim Khayat Paulo Pimentel de Assumpcao Rommel Mário Rodriguez Burbano Marília Cardoso Smith Danielle Queiroz Calcagno | 2016 | World Journal of Gastroenterology2016，22，35： | 11 |
| 8 | Biliary tract schwannoma:A rare cause of obstructive jaundice in a young patient显示文摘Schwannoma is a tumor derived from Schwann cells which usually arises in the upper extremities, trunk, head and neck, retroperitoneum, mediastinum, pelvis, and peritoneum. However, it can arise in the gastro-intestinal tract, including biliary tract. We present a 24-year-old male patient with obstructive jaundice, whose investigation with computed tomography abdomen showed focal wall thickening in the common hepatic duct, difficult to differentiate with hilar adenocarcinoma. He was diagnosed intraoperatively schwannoma of common bile duct and treated with local resection. The patient recovered well without signs of recurrence of the lesion after 12 mo. We also reviewed the common bile duct schwannoma related in the literature and evaluated the difficulty in pre and intraoperative differential diagnosis with adenocarcinoma hilar. Resection is the treatment of choice for such cases and the tumordid not recur in any of the resected cases. | Gilton Marques Fonseca André Luis Montagnini Manoel de Souza Rocha Rosely Antunes Patzina Mário Vinícius Angelete Alvarez Bernardes Ivan Cecconello José Jukemura | 2012 | World Journal of Gastroenterology2012，18，37： | 10 |
| 9 | Endoscopic stenting for inoperable malignant biliary obstruction: A systematic review and meta-analysis显示文摘AIM: To analyze through meta-analyses the benefits of two types of stents in the inoperable malignant biliary obstruction.METHODS: A systematic review of randomized clinical trials(RCT) was conducted, with the last update on March 2015, using EMBASE, CINAHL(EBSCO), MEDLINE, LILACS/CENTRAL(BVS), SCOPUS, CAPES(Brazil), and gray literature. Information of the selected studies was extracted in sight of six outcomes: primarily regarding dysfunction, complication and reintervention rates; and secondarily costs, survival, and patency time. The data about characteristics of trial participants, inclusion and exclusion criteria and types of stents were also extracted. The bias was mainly assessed through the JADAD scale. This meta-analysis was registered in the PROSPERO database by the number CRD42014015078. The analysis of the absolute risk of the outcomes was performed using the software Rev Man, by computing risk differences(RD) of dichotomous variables and mean differences(MD) of continuous variables. Data on RD and MD for each primary outcome were calculated using the MantelHaenszel test and inconsistency was qualified and reported in χ2 and the Higgins method(I2). Sensitivity analysis was performed when heterogeneity was higher than 50%, a subsequent assay was done and other findings were compiled. Student's t-test was used for the comparison of weighted arithmetic means regarding secondary outcomes.RESULTS: Initial searching identified 3660 studies; 3539 were excluded through title, repetition, and/or abstract, while 121 studies were fully assessed and were excluded mainly because they did not compare self-expanding metal stents(SEMS) and plastic stents(PS), leading to thirteen RCT selected, with 13 articles and 1133 subjects meta-analyzed. The mean age was 69.5 years old, that were affected mostly by bile duct(proximal) and pancreatic tumors(distal). The preferred SEMS diameter used was the 10 mm(30 Fr) and the preferred PS diameter used was 10 Fr. In the metaanalysis, SEMS had lower overall stent dysfunction compared to PS(21.6% vs 46.8%, P < 0.00001) and fewer re-interventions(21.6% vs 56.6%, P < 0.00001), with no difference in complications(13.7% vs 15.9%, P = 0.16). In the secondary analysis, the mean survival rate was higher in the SEMS group(182 d vs 150 d, P < 0.0001), with a higher patency period(250 d vs 124 d, P < 0.0001) and a lower cost per patient(4193.98 vs 4728.65 Euros, P < 0.0985).CONCLUSION: SEMS are associated with lower stent dysfunction, lower re-intervention rates, better survival, and higher patency time. Complications and costs showed no difference. | Leonardo Zorrón Pu Eduardo Guimaraes Hourneaux de Moura Wanderley Marques Bernardo Felipe Iankelevich Baracat Ernesto Quaresma Mendonca AndréKondo Gustavo Oliveira Luz Carlos Kiyoshi Furuya Júnior Everson Luiz de Almeida Artifon | 2015 | World Journal of Gastroenterology2015，21，47： | 10 |
| 10 | Interrelationship between chromosome 8 aneuploidy,C-MYC amplification and increased expression in individuals from northern Brazil with gastric adenocarcinoma显示文摘AIM: To investigate chromosome 8 numerical aberra- tions, C-MYC oncogene alterations and its expression in gastric cancer and to correlate these findings with histo- pathological characteristics of gastric tumors. METHODS: Specimens were collected surgically from seven patients with gastric adenocarcinomas. Immu- nostaining for C-MYC and dual-color fluorescence in situ hybridization (FISH) for C-MYC gene and chromosome 8 centromere were performed. RESULTS: All the cases showed chromosome 8 aneu- ploidy and C-MYC amplification, in both the diffuse and intestinal histopathological types of Lauren. No significant difference (P < 0.05) was observed between the level ofchromosome 8 ploidy and the site, stage or histological type of the adenocarcinomas. C-MYC high amplification, like homogeneously stained regions (HSRs) and double minutes (DMs), was observed only in the intestinal-type. Structural rearrangement of C-MYC, like translocation, was observed only in the diffuse type. Regarding C-MYC gene, a significant difference (P < 0.05) was observed between the two histological types. The C-MYC protein was expressed in all the studied cases. In the intestinal- type the C-MYC immunoreactivity was localized only in the nucleus and in the diffuse type in the nucleus and cytoplasm. CONCLUSION: Distinct patterns of alterations between intestinal and diffuse types of gastric tumors support the hypothesis that these types follow different genetic path- ways. | Danielle Queiroz Calcagno Mariana Ferreira Leal Aline Damaceno Seabra Andre Salim Khayat Elizabeth Suchi Chen Samia Demachki Paulo Pimentel Assumpcao Mario Henrique Girao Faria Silvia Helena Barem Rabenhorst Márcia Valéria Pitombeira Ferreira Marília de Arruda Cardoso Smith Rommel Rodríguez Burbano | 2006 | World Journal of Gastroenterology2006，12，38： | 9 |
| 11 | Transanal total mesorectal excision:Towards standardization of technique显示文摘AIM: To describe the role of Transanal total mesorectal excision(Ta TME) in minimally invasive rectal cancer surgery, to examine the differences in patient selection and in reported surgical techniques and their impactson postoperative outcomes and to discuss the future of Ta TME. METHODS: MEDLINE(Pub Med), EMBASE, and The Cochrane Library were systematically searched through the 1st of March 2015 using a predefined search strategy. RESULTS: A total of 20 studies with 323 patients were included. Most studies were single-arm prospective studies with fewer than 100 patients. Multiple transanal access platforms were used, and the laparoscopic approach was either multi- or single port. The procedure was initiated transanally or transabdominally. If a simultaneous approach with 2 operating surgeons was chosen, the operative time was significantly reduced. CONCLUSION: Ta TME was also associated with better TME specimens and a longer distal resection margin. Ta TME is thus feasible in expert hands, but the learning curve and safety profile are not well defined. Longterm follow-up regarding anal function and oncological outcomes should be performed in the future. | Albert M Wolthuis Gabriele Bislenghi Anthony de Buck van Overstraeten André D'Hoore | 2015 | World Journal of Gastroenterology2015，21，44： | 9 |
| 12 | Titanium dioxide induced inflammation in the small intestine显示文摘AIM:To investigate the effects of titanium dioxide (TiO2) nanoparticles (NPTiO 2 ) and microparticles (MPTiO 2 ) on the inflammatory response in the small intestine of mice. METHODS: Bl 57/6 male mice received distilled water suspensions containing TiO 2 (100 mg/kg body weight) as NPTiO 2 (66 nm), or MPTiO 2 (260 nm) by gavage for 10 d, once a day; the control group received only distilled water. At the end of the treatment the duodenum, jejunum and ileum were extracted for assessment of cytokines, inflammatory cells and titanium content. The cytokines interleukin (IL)-1b, IL-4, IL-6, IL-8, IL-10, IL-12, IL-13, IL-17, IL-23, tumor necrosis factor-α (TNF-α), intracellular interferon-γ (IFN-γ) and transforming growth factor-β (TGF-β) were evaluated by enzyme-linked immunosorbent assay in segments of jejunum and ileum (mucosa and underlying muscular tissue). CD4 + and CD8 + T cells, natural killer cells, and dendritic cells were evaluated in duodenum, jejunum and ileum samples fixed in 10% formalin by immuno-histochemistry. The titanium content was determined by inductively coupled plasma atomic emission spectrometry. RESULTS: We found increased levels of T CD4 + cells (cells/mm 2 ) in duodenum:NP 1240 ± 139.4, MP 1070 ± 154.7 vs 458 ± 50.39 (P < 0.01); jejunum:NP 908.4 ± 130.3, MP 813.8 ± 103.8 vs 526.6 ± 61.43 (P < 0.05); and ileum:NP 818.60 ± 123.0, MP 640.1 ± 32.75 vs 466.9 ± 22.4 (P < 0.05). In comparison to the control group, the groups receiving TiO 2 showed a statistically significant increase in the levels of the inflammatory cytokines IL-12, IL-4, IL-23, TNF-α, IFN-γ and TGF-β. The cytokine production was more pronounced in the ileum (mean ± SE):IL-12: NP 33.98 ± 11.76, MP 74.11 ± 25.65 vs 19.06 ± 3.92 (P < 0.05); IL-4: NP 17.36 ± 9.96, MP 22.94 ± 7.47 vs 2.19 ± 0.65 (P < 0.05); IL-23: NP 157.20 ± 75.80, MP 134.50 ± 38.31 vs 22.34 ± 5.81 (P < 0.05); TNFα: NP 3.71 ± 1.33, MP 5.44 ± 1.67 vs 0.99± 019 (P < 0.05); IFNγ: NP 15.85 ± 9.99, MP 34.08 ± 11.44 vs 2.81 ± 0.69 (P < 0.05); and TGF-β: NP 780.70 ± 318.50, MP 1409.00 ± 502.20 vs 205.50 ± 63.93 (P < 0.05). CONCLUSION:Our findings indicate that TiO2 particles induce a Th1-mediated inflammatory response in the small bowel in mice. | Carolina Maciel Nogueira Walter Mendes de Azevedo Maria Lucia Zaidan Dagli Sérgio Hiroshi Toma AndréZonetti de Arruda Leite Maria Laura Lordello Iêda Nishitokukado Carmen Lúcia Ortiz-Agostinho Maria IrmaSeixas Duarte Marcelo Alves Ferreira Aytan Miranda Sipahi | 2012 | World Journal of Gastroenterology2012，18，34： | 8 |
| 13 | Short-term complementary and alternative medicine on quality of life in women with fibromyalgia显示文摘BACKGROUND:Fibromyalgia(FMS)is a syndrome characterized by chronic widespread musculoskeletal pain,whose etiology is not completely understood.Different therapeutic approaches have been used with inconsistent results.This observation does not invalidate the continued search for alternative treatments aimed at improving quality of life(Qo L)in FMS.OBJECTIVE:This study compared three classical traditional Chinese medicine(TCM)therapies:acupuncture(AC),electroacupuncture(EAC)and moxibustion(MX)in the management of pain and promotion of Qo L in FMS patients.DESIGN,SETTING,PARTICIPANTS AND INTERVENTIONS:A preliminary,group-assigned,comparative study enrolled 30 women,mean age(46.90±9.24)years(range 20–60 years),who met the 1990 American College of Rheumatology criteria for FMS diagnosis and a pain-pressure threshold(PPT)< 4 kg/cm^2.The study was conducted in a teaching tertiary-care medical institution from May 2010 through April 2012.AC,EAC and MX were delivered for 30 min,once a week,for 8 weeks,bilaterally at Neiguan(PC6),Hegu(LI4),Yanglingquan(GB34),Sanyinjiao(SP6)and Taichong(LR3)acupoints.MAIN OUTCOME MEASURES:Each week,immediately before treatment and after treatment,subjects were tested for PPTs,Wong-Baker Faces Pain Scale(WBFPS;for pain intensity)and Medical Outcomes Study 36-item Short Form Health Survey(SF-36:for Qo L).RESULTS:There was no signifi cant improvement in pain or reduction of tender points in any of the groups studied,at the end of the 8th session.Signifi cant improvement of Qo L was perceived in vitality(after AC treatment)and in mental health(after EAC and MX treatments).CONCLUSION:TCM therapies(AC,EAC and MX)promoted an improvement in the Qo L in two areas(vitality and mental health)in FMS women.Further large-scale clinical trials are required to confi rm this effect. | Paulo Araujo Dias Andre Brito Bastos Guimaraes Andrea de Oliveira Albuquerque Karoline Lucas de Oliveira Maria Luzete Costa Cavalcante Sergio Botelho Guimaraes | 2016 | Journal of Integrative Medicine2016，14，1： | 7 |
| 14 | Systematic review: The placebo effect of psychological interventions in the treatment of irritable bowel syndrome显示文摘AIM To determine the placebo response rate associated with different types of placebo interventions used in psychological intervention studies for irritable bowel syndrome. METHODS Randomized controlled trials comparing psychological interventions(stress management/relaxation therapy(cognitive) behavioral therapy, short-term psychodynamic therapy, and hypnotherapy) for the treatment of adult patients with irritable bowel syndrome(IBS) diagnosed with the Manning or Rome criteria with an adequate placebo control treatment and reporting data on IBS symptom severity were identified by searching Pub Med, Embase, the Cochrane Library, CINAHL and Psyc INFO databases. Full-text articles that were written in English and published between 1966 and February 2016 in peer-reviewed journals were selected for the present review. Placebo interventions were considered to be adequate if the number of sessions and the amount of time spent with the therapist were the same as in the active treatment. The placebo response rate(PRR) was computed for IBS symptom severity(primary outcome measure) as well as for anxiety, depression and quality of life(secondary outcome measures). RESULTS Six studies, with a total of 555 patients met the inclusion criteria. Four studies used an educational intervention, whereas two studies used a form of supportive therapy as the placebo intervention. The PRR for IBS symptom severity ranged from 25% to 59%, with a pooled mean of 41.4%. The relative PRR for the secondary outcome measures ranged from 0% to 267% for anxiety, 6% to 52% for depression 20% to 125% for quality of life. The PRR associated with pharmacological treatments, treatment with dietary bran and complementary medicine ranged from 37.5% to 47%. Contrary to our expectations, the PRR in studies on psychological interventions was comparable to that in studies on pharmacological, dietary and alternative medical interventions.CONCLUSION The PRR is probably determined to a larger extent by patient-related factors, such as expectations and desire for the treatment to be effective, than the content of the placebo intervention. | Carla E Flik Laura Bakker Wijnand Laan Yanda R van Rood André JPM Smout Niek J de Wit | 2017 | World Journal of Gastroenterology2017，23，12： | 7 |
| 15 | Cyano-containing ionic liquids for the extraction of aromatic hydrocarbons from an aromatic/aliphatic mixture显示文摘Ionic liquids can replace conventional solvents in aromatic/aliphatic extractions, if they have higher aromatic distribution coef- ficients and higher or similar aromatic/aliphatic selectivities. Also physical properties, such as density and viscosity, must be taken into account if a solvent is applied in an industrial extraction process. Cyano-containing ionic liquids have a lower den- sity than the benchmark solvent sulfolane and a higher viscosity. Sulfolane is from a hydrodynamic point of view a better sol- vent than ionic liquids for the aromatic/aliphatic extraction. The most suitable ionic liquids for the extraction of aromatic hy- drocarbons from a mixture of aromatic and aliphatic hydrocarbons are [bmim]C(CN)3, [3-mebupy]N(CN)2, [3-mebupy]C(CN)3, [3-mebupy]B(CN)4 and [mebupyrr]B(CN)4. They have factors of 1.2-2.3 higher mass-based distribution coefficients than sul- folane and a similar or higher, up to a factor of 1.9 higher, aromatic/aliphatic selectivity than sulfolane.

| 16 | Chronic stress sensitizes rats to pancreatitis induced by cerulein:Role of TNF-α显示文摘AIM:To investigate chronic stress as a susceptibility factor for developing pancreatitis,as well as tumor necrosis factor-α (TNF-α) as a putative sensitizer.METHODS:Rat pancreatic acini were used to analyze the influence of TNF-α on submaximal (50 pmol/L) cholecystokinin (CCK) stimulation.Chronic restraint (4 h every day for 21 d) was used to evaluate the effects of submaximal (0.2 μg/kg per hour) cerulein stimulation on chronically stressed rats.RESULTS:In vitro exposure of pancreatic acini toTNF-α disorganized the actin cytoskeleton.This was further increased by TNF-α/CCK treatment,which additionally reduced amylase secretion,and increased trypsin and nuclear factor-κB activities in a protein-kinase-C δ and ε-dependent manner.TNF-α/CCK also enhanced caspases' activity and lactate dehydrogenase release,induced ATP loss,and augmented the ADP/ATP ratio.In vivo,rats under chronic restraint exhibited elevated serum and pancreatic TNF-α levels.Serum,pancreatic,and lung inflammatory parameters,as well as caspases' activity in pancreatic and lung tissue,were substantially enhanced in stressed/cerulein-treated rats,which also experienced tissues' ATP loss and greater ADP/ATP ratios.Histological examination revealed that stressed/cerulein-treated animals developed abundant pancreatic and lung edema,hemorrhage and leukocyte infiltrate,and pancreatic necrosis.Pancreatitis severity was greatly decreased by treating animals with an anti-TNF-αantibody,which diminished all inflammatory parameters,histopathological scores,and apoptotic/necrotic markers in stressed/cerulein-treated rats.CONCLUSION:In rats,chronic stress increases susceptibility for developing pancreatitis,which involves TNF-α sensitization of pancreatic acinar cells to undergo injury by physiological cerulein stimulation. | Marcelo G Binker Andres A Binker-Cosen Daniel Richards Herbert Y Gaisano Rodica H de Cosen Laura I Cosen-Binker | 2010 | World Journal of Gastroenterology2010，16，44： | 7 |
| 17 | Insights into gastric neuroendocrine tumors burden显示文摘Type 1 gastric neuroendocrine tumors(g NETs)are usually small lesions,restricted to mucosal and sub-mucosal layers of corpus and fundus,with low aggressive behavior,for the majority of cases.Nevertheless,some cases present aggressive behavior.The increasing incidence of g NETs brings together a new relevant problem:how to identify potentially aggressive type 1 g NETs.The challenging problem seems to be finding out signs or features able to predict potentially aggressive cases,allowing a tailored approach,since the involved societies dedicated to provide guidelines for management of these neoplasms apparently failed in producing staging systems able to accurately predict prognosis of these tumors.Additionally,it is also important to try to find out explanations for increasing incidence,as well as to identify potential targets aiming to reach better control of this neoplasia.Here,we discuss potential pathways implicated in aggressive behavior,as well as new strategies to improve clinical management of these tumors. | Taíssa Maíra Thomaz Araújo Williams Fernandes Barra André Salim Khayat Paulo Pimentel de Assumpcao | 2017 | Chinese Journal of Cancer Research2017，29，2： | 7 |
| 18 | Association between Helicobacterpylori, Epstein-Barr virus, human papillomavirus and gastric adenocarcinomas显示文摘AIM To correlate Helicobacter pylori(H. pylori), Epstein-Barr virus(EBV) and human papillomavirus(HPV) with gastric cancer(GC) cases in Pará State, Brazil.METHODS Tissue samples were obtained from 302 gastric adenocarcinomas. A rapid urease test was used to detect the presence of H. pylori, and the presence of the cagA gene in the HP-positive samples was confirmed by PCR. An RNA in situ hybridization test designed to complement Eber1 RNA was used to detect the presence of EBV in the samples, and the L1 region of HPV was detected using nested PCR. Positive HPV samples were genotyped and analyzed for E6 and E7 viral gene expression. Infections were also correlated with the clinical and pathological characteristics of the patients.RESULTS The majority of the 302 samples analyzed were obtained from men(65%) aged 55 years or older(67%) and were classified as the intestinal subtype(55%). All three pathogens were found in the samples analyzed in the present study(H. pylori : 87%, EBV: 20%, HPV: 3%). Overall, 78% of the H. pylori-positive(H. pylori+) samples were cag A +(H. pylori-cag A+), and there was an association between the cytotoxic product of this gene and EBV. Coinfections of H. pylori-cagA+ and EBV were correlated with the most advanced tumor stages. Although only 20% of the tumors were positive for EBV, infection with this virus was associated with distant metastasis. Only the HPV 16 and 18 strains were found in the samples, although no expression of the E6 and E7 oncoproteins was detected. The fundus of the stomach was the region least affected by the pathogens.CONCLUSION HPV was not involved in gastric tumorigenesis. Prophylactic and therapeutic measures against H. pylori and EBV may prevent the development of GC, especially the more aggressive forms. | Carolina Rosal Teixeira de Souza Marcelli Carolini Alves Almeida Andre Salim Khayat Emerson Lucena da Silva Paulo Cardoso Soares Luiz Claudio Chaves Rommel Mario Rodriguez Burbano | 2018 | World Journal of Gastroenterology2018，24，43： | 6 |
| 19 | Pulmonary vein stenosis:Etiology,diagnosis and management显示文摘Pulmonary vein stenosis(PVS) is rare condition characterized by a challenging diagnosis and unfavorable prognosis at advance stages. At present, injury from radiofrequency ablation for atrial fibrillation has become the main cause of the disease. PVS is characterized by a progressive lumen size reduction of one or more pulmonary veins that, when hemodynamically significant, may raise lobar capillary pressure leading to signs and symptoms such as shortness of breath, cough, and hemoptysis. Image techniques(transesophageal echocardiography, computed tomography, magnetic resonance and perfusion imaging) are essential to reach a final diagnosis and decide an appropriate therapy. In this regard, series from referral centers have shown that surgical and transcatheter interventions may improve prognosis. The purpose of this article is to review the etiology, assessment and management of PVS. | Pablo Pazos-López Cristina García-Rodríguez Alba Guitián-González Emilio Paredes-Galán María ángel De La Guarda álvarez-Moure Marta Rodríguez-álvarez José Antonio Baz-Alonso Elvis Teijeira-Fernández Francisco Eugenio Calvo-Iglesias Andrés íniguez-Romo | 2016 | World Journal of Cardiology2016，8，1： | 6 |
| 20 | Transcranial direct current stimulation in psychiatric disorders显示文摘The interest in non-invasive brain stimulation techniques is increasing in recent years. Among these techniques, transcranial direct current stimulation(t DCS) has been the subject of great interest among researchers because of its easiness to use, low cost, benign profile of side effects and encouraging results of research in the field. This interest has generated several studies and randomized clinical trials, particularly in psychiatry. In this review, we provide a summary of the development of the technique and its mechanism of action as well as a review of the methodological aspects of randomized clinical trials in psychiatry, including studies in affective disorders, schizophrenia, obsessive compulsive disorder, child psychiatry and substance use disorder. Finally,we provide an overview of t DCS use in cognitive enhancement as well as a discussion regarding its clinical use and regulatory and ethical issues. Although many promising results regarding t DCS efficacy were described, the total number of studies is still low, highlighting the need of further studies aiming to replicate these findings in larger samples as to provide a definite picture regarding t DCS efficacy in psychiatry. | Gabriel Tortella Roberta Casati Luana V M Aparicio Antonio Mantovani Natasha Senco Giordano D’Urso Jerome Brunelin Fabiana Guarienti Priscila Mara Lorencini Selingardi Débora Muszkat Bernardo de Sampaio Pereira Junior Leandro Valiengo Adriano H Moffa Marcel Simis Lucas Borrione André R Brunoni | 2015 | World Journal of Psychiatry2015，5，1： | 6 |
