| 1 | Different profile of cytokine synthesis according to the severity of acute pancreatitis显示文摘AIM: To evaluate the cellular synthetic ability of cytokines involved in pro- and anti-inflammatory reactions in patients with AP.METHODS: Sixty-seven patients with AP (16 severe,51 mild) and 10 controls were included in the study.Cultures of whole blood were performed in samples obtained within the first 72 h from the onset of pain.Serum levels of interleukins (IL) 6, 8, 10, and TNF-α were measured at baseline and in the supernatant of cultures with (functional reserve) or without stimulation with phytohemaglutinin.RESULTS: Basal levels of cytokines were significantly higher in patients with severe AP. A significant increase of all pro-inflammatory cytokines vs basal levels was observed in the supernatant after 24 h of whole blood cultures in patients, but not in controls. In contrast, IL-10 increased significantly in the supernatant of cultures only in patients with mild AP. Cells showed a statistically significant functional reserve for all IL in patients with mild, but only for pro-inflammatory cytokines in patients with severe AP.CONCLUSION: A marked activation of immune system may be observed in patients with AP, being balanced between pro- and anti-inflammatory cytokines in patients with mild but not severe AP. A reduced functional reserve for the synthesis of IL-10 may be observed in patients with severe AP, which might lead to a worst prognosis. | Raquel Laveda Juan Martínez Carlos Mu■oz Juan Carlos Penalva Jesus Sáez Germán Belda Salvador Navarro Faust Feu Anton Mas José Ma Palazón José Sánchez-Payá José Such Miguel Pérez-Mateo | 2005 | World Journal of Gastroenterology2005，11，34： | 24 |
| 2 | Clinical value of rapid urine trypsinogen-2 test strip, urinary trypsinogen activation peptide, and serum and urinary activation peptide of carboxypeptidase B in acute pancreatitis显示文摘AIM: To assess the usefulness of urinary trypsinogen-2 test strip, urinary trypsinogen activation peptide (TAP),and serum and urine concentrations of the activation peptide of carboxypeptidase B (CAPAP) in the diagnosisof acute pancreatitis.METHODS: Patients with acute abdominal pain and hospitalized within 24 h after the onset of symptoms were prospectively studied. Urinary trypsinogen-2 was considered positive when a clear blue line was observed (detection limit 50 μg/L). Urinary TAP was measured using a quantitative solid-phase ELISA, and serum and urinary CAPAP by a radioimmunoassay method.RESULTS: Acute abdominal pain was due to acute pancreatitis in 50 patients and turned out to be extrapancreatic in origin in 22 patients. Patients with acute pancreatitis showed significantly higher median levels of serum and urinary CAPAP levels, as well as amylase and lipase than extrapancreatic controls. Median TAP levels were similar in both groups. The urinary trypsinogen-2 test strip was positive in 68% of patients with acute pancreatitis and 13.6% in extrapancreatic controls (P<0.01). Urinary CAPAP was the most reliable test for the diagnosis of acute pancreatitis (sensitivity 66.7%, specificity 95.5%, positive and negative predictive values 96.6% and 56.7%, respectively), with a 14.6 positive likelihood ratio for a cut-off value of 2.32 nmol/L.CONCLUSION: In patients with acute abdominal pain,hospitalized within 24 h of symptom onset, CAPAP in serum and urine was a reliable diagnostic marker of acute pancreatitis. Urinary trypsinogen-2 test strip showed a clinical value similar to amylase and lipase.Urinary TAP was not a useful screening test for the diagnosis of acute pancreatitis. | Jesús Sáez Juan Martínez Celia Trigo José Sánchez-Payá Luis Compay Raquel Laveda Pilar Grió Cristina García Miguel Pérez-Mateo | 2005 | World Journal of Gastroenterology2005，11，46： | 21 |
| 3 | Recruitment maneuvers in acute respiratory distress syndrome: The safe way is the best way显示文摘Acute respiratory distress syndrome(ARDS) represents a serious problem in critically ill patients and is associated with in-hospital mortality rates of 33%-52%. Recruitment maneuvers(RMs) are a simple, low-cost, feasible intervention that can be performed at the bedside in patients with ARDS. RMs are characterized by the application of airway pressure to increase transpulmonary pressure transiently. Once non-aerated lung units are reopened, improvements are observed in respiratory system mechanics, alveolar reaeration on computed tomography, and improvements in gas exchange(functional recruitment). However, the reopening process could lead to vascular compression, which can be associated with overinflation, and gas exchange may not improve as expected(anatomical recruitment). The purpose of this review was to discuss the effects of different RM strategies- sustained inflation, intermittent sighs, and stepwise increases of positive end-expiratory pressure(PEEP) and/or airway inspiratory pressure- on the following parameters: hemodynamics, oxygenation, barotrauma episodes, and lung recruitability through physiological variables and imaging techniques. RMs and PEEP titration are interdependent events for the success of ventilatory management. PEEP should be adjusted on the basis of respiratory system mechanics and oxygenation. Recent systematic reviews and meta-analyses suggest that RMs are associated with lower mortality in patients with ARDS. However, the optimal RM method(i.e., that providing the best balance of benefit and harm) and the effects of RMs on clinical outcome are still under discussion, and further evidence is needed. | Raquel S Santos Pedro L Silva Paolo Pelosi Patricia RM Rocco | 2015 | World Journal of Critical Care Medicine2015，4，4： | 19 |
| 4 | Causes and consequences of microsatellite instability in gastric carcinogenesis显示文摘Loss of DNA mismatch repair(MMR) function, due to somatic or germline epi/genetic alterations of MMR genes leads to the accumulation of numerous mutations across the genome, creating a molecular phenotype known as microsatellite instability(MSI). In gastric cancer(g C), MSI occurs in about 15% to 30% of the cases. This review summarizes the current knowledge on the molecular mechanisms underlying the acquisition of MSI in g C as well as on the clinic, pathologic and molecular consequences of the MSI phenotype. Additionally, current therapeutic strategies for g C and their applicability in the MSI subset are also discussed. | Sérgia Velho Maria Sofia Fernandes Marina Leite Ceu Figueiredo Raquel Seruca | 2014 | World Journal of Gastroenterology2014，20，44： | 14 |
| 5 | Phase angle obtained by bioelectrical impedance analysis independently predicts mortality in patients with cirrhosis显示文摘AIM To evaluate the prognostic value of the phase angle(PA)obtained from bioelectrical impedance analysis(BIA) for mortality prediction in patients with cirrhosis. METHODS In total, 134 male cirrhotic patients prospectively completed clinical evaluations and nutritional assessment by BIA to obtain PAs during a 36-mo follow-up period. Mortality risk was analyzed by applying the PA cutoff point recently proposed as a malnutrition marker(PA ≤ 4.9°) in Kaplan-Meier curves and multivariate Cox regression models. RESULTS The patients were divided into two groups according to the PA cutoff value(PA > 4.9°, n = 73; PA ≤ 4.9°, n = 61). Weight, height, and body mass index were similar in both groups, but patients with PAs > 4.9° were younger and had higher mid-arm muscle circumference, albumin, and handgrip-strength values and lower severe ascites and encephalopathy incidences, interleukin(IL)-6/IL-10 ratios and C-reactive protein levels than did patients with PAs ≤ 4.9°(P ≤ 0.05). Forty-eight(35.80%) patients died due to cirrhosis, with a median of 18 mo(interquartile range, 3.3-25.6 mo) follow-up until death. Thirty-one(64.60%) of these patients were from the PA ≤ 4.9° group. PA ≤ 4.9° significantly and independently affected the mortality model adjusted for Model for End-Stage Liver Disease score and age(hazard ratio = 2.05, 95%CI: 1.11-3.77, P = 0.021). In addition, Kaplan-Meier curves showed that patients with PAs ≤ 4.9° were significantly more likely to die. CONCLUSION In male patients with cirrhosis, the PA ≤ 4.9° cutoff was associated independently with mortality and identified patients with worse metabolic, nutritional, and disease progression profiles. The PA may be a useful and reliable bedside tool to evaluate prognosis in cirrhosis. | Giliane Belarmino Maria Cristina Gonzalez Raquel S Torrinhas Priscila Sala Wellington Andraus Luiz Augusto Carneiro D'Albuquerque Rosa Maria R Pereira Valéria F Caparbo Graziela R Ravacci Lucas Damiani Steven B Heymsfield Dan L Waitzberg | 2017 | World Journal of Hepatology2017，9，7： | 11 |

| 7 | Sex-specific effects of Eugenia punicifolia extract on gastric ulcer healing in rats显示文摘AIM To evaluate the sex-specific effects of a hydroalcoholic extract from Eugenia punicifolia(HEEP) leaves on gastric ulcer healing.METHODS In this rat study involving males, intact(cycling) females, and ovariectomized females, gastric ulcers were induced using acetic acid. A vehicle, lansoprazole, or HEEP was administered for 14 d after ulcer induction. Body weight was monitored throughout the treatment period. At the end of treatment, the rats were euthanized and the following in vivo and in vitro investigations were performed: macroscopic examination of the lesion area and organ weights, biochemical analysis, zymography, and evaluation of protein expression levels. Additionally, the concentration-dependent effect of HEEP was evaluated in terms of subacute toxicity and cytotoxicity.RESULTS Compared to the vehicle, HEEP demonstrated a great healing capacity by substantially reducing the ulcerative lesion area in males(52.44%), intact females(85.22%), and ovariectomized females(65.47%), confirming that HEEP accelerates the healing of acetic acidinduced gastric lesions and suggesting that this effect is modulated by female sex hormones. The antiulcer effect of HEEP was mediated by prostaglandin E2 only in male rats. Overall, the beneficial effect of HEEP was the highest in intact females. Notably, HEEP promoted the expression of vascular endothelial growth factor(intact vs ovariectomized females) and decreased the expression of Caspase-8 and Bcl-2(intact female vs male or ovariectomized female). Additionally, HEEP enhanced fibroblast proliferation and migration into a wounded area in vitro, confirming its healing effect. Finally, no sign of subacute toxicity or cytotoxicity of HEEP was observed.CONCLUSION In gastric ulcers, HEEP-induced healing(modulated by female sex hormones; in males, mediated by prostaglandin) involves extracellular matrix remodeling, with gastric mucosa cell proliferation and migration. | Larissa Lucena Périco Vinícius Peixoto Rodrigues Rie Ohara Gabriela Bueno Vania Vasti Alfieri Nunes Raquel Cássia dos Santos Ana Carolina Lima Camargo Luis Antuio Justulin Joior Sérgio Faloni de Andrade Viviane Miranda Bispo Steimbach Luísa Mota da Silva Lúcia Regina Machado da Rocha Wagner Vilegas Catarina dos Santos Clélia Akiko Hiruma-Lima | 2018 | World Journal of Gastroenterology2018，24，38： | 3 |

| 9 | Ascorbic acid and prunasin,two candidate biomarkers for endodormancy release in almond flower buds identified by a nontargeted metabolomic study显示文摘Temperate fruit trees belonging to Prunus species have the ability to suspend(induce dormancy)and resume growth periodically in response to environmental and seasonal conditions.Endodormancy release requires the long-term accumulation of chill.Upon accumulation of cultivar-specific chill requirements,plants enter the state of ecodormancy,which means the ability to grow has been restored,depending on the fulfilment of heat requirements.As many different metabolic pathways are implicated in endodormancy release,we have performed a metabolomic analysis,using the ultra-high-performance liquid chromatography–quadrupole time-of-flying(UPLC–QToF)technique.We assayed flower buds in different stages of endodormancy in four almond cultivars with different flowering times:the extra-early Desmayo Largueta,the late Antoñeta,the extra-late Penta,and the ultra-late Tardona.An orthogonal projection to latent-structure discriminant-analysis model was created to observe differences between endodormant and ecodormant flower buds.The metabolites showing the most significant variation were searched against the Metlin,HMDB,and KEGG libraries,which allowed us to identify 87 metabolites.These metabolites were subsequently assigned to specific pathways,such as abscisic acid biosynthesis,phenylpropanoid biosynthesis,and D-sorbitol metabolism,among others.The two metabolites that exhibited the most significant variations in all the cultivars studied with fold changes of up to 6.49 were ascorbic acid and prunasin.For the first time,these two metabolites have been proposed as potential biomarkers for endodormancy release in almond.Given the high synteny present between the Rosaceae species,these results could be extrapolated to other important crops like peach,plum,cherry,or apricot,among others. | Jesús Guillamón Guillamón Ángela Sánchez Prudencio JoséEnrique Yuste Federico Dicenta Raquel Sánchez-Pérez | 2020 | Horticulture Research2020，7，1： | 2 |
| 10 | Paclobutrazol and Its Use in Fruit Production:A Review显示文摘There are documentary records referring to paclobutrazol(PBZ)as a growth bioregulator that inhibits the gibberellin synthesis and its application increases yields in fruit and vegetable crop productions.Its agronomic management includes it as an emerging technology to reduce vigour,promote flower induction and flower development in fruit trees with increased economic returns.Its use is banned in some countries because of concerns about residues that can cause harmful effects on the environment.Therefore,the aim of this article was to collect,analyse and summarise relevant information on the use of PBZ in fruit tree production and its possible risks to the environment.The results obtained indicated that the application of PBZ can be effective in solving some problems related to flowering if it is applied in the right amount and at the right time.However,it is necessary to elucidate the physiological processes with which it is associated and its response to be taken into account to increase yield.PBZ is currently used in fruit trees such as mango,lime,apple and guava,increasing their productivity.However,some studies have shown its residual effect on the environment.Therefore,PBZ is a viable strategy,because it presents a series of advantages in the production of fruit trees.However,it is vital to generate protocols that seek its regulation with a rational and sustainable approach. | Laura Raquel Orozco-Meléndez Ofelia Adriana Hernández-Rodríguez Oscar Cruz-Álvarez Loreto Robles-Hernández Graciela Dolores Avila-Quezada Esteban Sánchez Chavez DamiánAarón Porras-Flores Dámaris Leopoldina Ojeda-Barrios | 2022 | Phyton-International Journal of Experimental Botany2022，91，1： | 2 |

| 13 | Prophylaxis with ketotifen in rats with portal hypertension:involvement of mast cell and eicosanoids显示文摘BACKGROUND:Since we have previously shown an increase of mast cells in the small bowel and in the mesenteric lymph nodes in the rats with prehepatic portal hypertension,it can be hypothesized that this essential inflammatory cell would be involved in the pathogeny of the splanchnic changes related to portal hypertension. METHODS:To verify this hypothesis,we first studied mast cell infiltration in the ileum and in the mesenteric lymph nodes in sham-operated male Wistar rats(n=12) and in short-term prehepatic portal hypertensive rats (n=12),and the serum levels of rat mast cell protease Ⅱ(RMCP-Ⅱ)by ELISA.In a second set of experiments ketotifen,a mast cell stabilizer drug,was administered to sham-operated(n=10)and portal hypertensive(n=12) rats 24 hours before the intervention and prostanoids (PGE2,PGI2,TXB2)and leukotrienes(LTC4,LTB4)were assayed by RIA,mast cell infiltration in the ileum and in the mesenteric lymph nodes and the serum levels of RMCP-Ⅱwere also studied,to show its effectiveness to prevent the mesenteric alterations produced by the inflammatory mediators released by the mast cell. RESULTS:Forty-eight hours after the intervention RMCP-Ⅱ (P<0.05),PGE2(P<0.001)and LTC4 serum levels decreased and mast cell number and RMCP-Ⅱlevels increased in mesenteric lymph nodes in portal hypertensive rats.Prophylactic administration of ketotifen reduced portal pressure(P<0.001),serum levels of PGE2(P<0.001)and RMCP-Ⅱ(P<0.001)in mesenteric lymph nodes. CONCLUSIONS:In acute portal hypertension in the rat,the mast cell translocation from intestinal mucosa to mesenteric lymph nodes,where they are activated and degranulates,would represent a defence mechanism to avoid the activation of an acute and massive inflammatory response in this location.Prophylactic administration of ketotifen is able to reduce the splanchnic inflammatory changes related to acute portal hypertension in the rat. | Fernando Sánchez-Patán Raquel Anchuelo Elena Vara Cruz García Yolanoa Saavedra Patri Vergara Carmen Cuellar Marta Rodero Maria-Angeles Aller Jaime Arias | 2008 | Hepatobiliary & Pancreatic Diseases International2008，7，4： | 2 |

| 16 | Family history and disease outcomes in patients with Crohn's disease:A comparison between China and the United States显示文摘AIM To investigate the differences in family history of inflammatory bowel disease(IBD) and clinical outcomes among individuals with Crohn's disease(CD) residing in China and the United States.METHODS We performed a survey-based cross-sectional study of participants with CD recruited from China and the United States.We compared the prevalence of IBD family history and history of ileal involvement,CD-related surgeries and IBD medications in China and the United States,adjusting for potential confounders.RESULTS We recruited 49 participants from China and 145 from the United States.The prevalence of family history of IBD was significantly lower in China compared with the United States(China:4.1%,United States:39.3%).The three most commonly affected types of relatives were cousin,sibling,and parent in the United States compared with child and sibling in China.Ileal involvement(China:63.3%,United States:63.5%) and surgery for CD(China:51.0%,United States:49.7%) were nearly equivalent in the two countries.CONCLUSION The lower prevalence of familial clustering of IBD in China may suggest that the etiology of CD is less attributed to genetic background or a family-shared environment compared with the United States.Despite the potential difference in etiology,surgery and ileal involvement were similar in the two countries.Examining the changes in family history during the continuing rise in IBD may provide further insight into the etiology of CD. | Pei-Qi Wang Jun Hu Elie S Al Kazzi Eboselume Akhuemonkhan Min Zhi Xiang Gao Raquel Holand de Paula Pessoa Sami Ghazaleh Tuhina Cornelius Suhel Abbas Sabunwala Shadi Ghadermarzi Kartikeya Tripathi Mark Lazarev Pin-Jin Hu Susan Hutfless | 2016 | World Journal of Gastrointestinal Pharmacology and Therapeutics2016，7，4： | 2 |
