| 2 | Dehydration melting of solid amphibolite at 2.0 GPa: Effects of time and temperature显示文摘Two sets of dehydration-melting with a natural solid amphibolite, collected from North Himalayan structure zone, Tibet, have been carried out in multi-anvil apparatus at 2.0 GPa and 800―1000℃, for 12―200 h. One is keeping the pressure at 2.0 GPa and the annealing time of 12 h, changing the temperature (800―1000℃). The other is keeping the pressure at 2.0 GPa and temperature at 850℃, varying the annealing time (12―200 h). The products are inspected with microscope and electron probe. The results indicate that at 2.0 GPa, annealing time of 12 h, garnets, melts and clinopyroxenes occur in amphibolite gradually with increasing temperature and the chemical compositions of melt vary from tonalite to granodiorite, and then to tonalite. However, at 2.0 GPa and 850℃, with the annealing time increasing, the garnets, melts and cli-nopyroxenes also occur in amphibolite gradually and the chemical compositions of melt vary from tonalite to granodiorite. In both cases, melts interconnect with each other when the contents of melt are over the 5 vol.%. the viscosities of the melt produced in amphibolite at temperature higher than 850℃ are on a level with 104 Pa·s. The interconnected melt with such a viscosity may segregate from the source rock and form the magma over reasonable geological time. Therefore, it is believed that at the lower part of the overthickened crust, the tonlitic and grano-dioritic magma may be generated through the dehydration melting of amphibolite. | ZHOU Wenge1, XIE Hongsen1, LIU Yonggang1, ZHENG Xiaogang1, ZHAO Zhidan2 & ZHOU Hui3 1.

| 5 | Contrast-enhanced ultrasound in diagnosis and characterization of focal hepatic lesions显示文摘The extensive use of imaging techniques in differential diagnosis of abdominal conditions and screening of hepatocellular carcinoma in patients with chronic hepatic diseases,has led to an important increase in identification of focal liver lesions.The development of contrastenhanced ultrasound(CEUS) opens a new window in the diagnosis and follow-up of these lesions.This technique offers obvious advantages over the computed tomography and magnetic resonance,without a decrease in its sensitivity and specificity.The new second generation contrast agents,due to their intravascular distribution,allow a continuous evaluation of the enhancement pattern,which is crucial in characterization of liver lesions.The dual blood supply in the liver shows three different phases,namely arterial,portal and late phases.The enhancement during portal and late phases can give important information about the lesion's behavior.Each liver lesion has a different enhancement pattern that makes possible an accurate approach to their diagnosis.The role of emerging techniques as a contrastenhanced three-dimensional US is also discussed.In this article,the advantages,indications and technique employed during CEUS and the different enhancement patterns of most benign and malignant focal liver lesions are discussed. | Inés Gómez Molins Juan Manuel Fernández Font Juan Carrero álvaro Jose Luís Lledó Navarro Marta Fernández Gil Conrado M Fernández Rodríguez | 2010 | World Journal of Radiology2010，2，12： | 14 |
| 6 | Accuracy and responses of genomic selection on key traits in apple breeding显示文摘The application of genomic selection in fruit tree crops is expected to enhance breeding eficiency by increasing prediction accuracy,increasing selection intensity and decreasing generation interval.The objectives of this study were to assess the accuracy of prediction and selection response in commercial apple breeding programmes for key traits.The training population comprised 977 individuals derived from 20 pedigreed fllsib families.Historic phenotypic data were available on 10 traits related to productivity and fruit external appearance and genotypic data for 7829 SNPs obtained with an llumina 20K SNP array.From these data,a genome-wide prediction model was built and subsequently used to calculate genomic breeding values of five application fllsib families.The application families had genotypes at 364 SNPs from a dedicated 512 SNP array,and these genotypic data were extended to the high-density level by imputation.These five families were phenotyped for 1 year and their phenotypes were compared to the predicted breeding values.Accuracy of genomic prediction across the 10 traits reached a maximum value of 0.5 and had a median value of 0.19.The accuracies were strongly affected by the phenotypic distribution and heritability of traits.In the largest family,significant selection response was observed for traits with high heritability and symmetric phenotypic distribution.Traits that showed non-significant response often had reduced and skewed phenotypic variation or low heritability.Among the five application families the accuracies were uncorrelated to the degree of relatedness to the training population.The results underline the potential of genomic prediction to accelerate breeding progress in outbred fruit tree crops that still need to overcome long generation intervals and extensive phenotyping costs. | Hélène Muranty Michela Troggio Inès Ben Sadok Mehdi Al Rifaï Annemarie Auwerkerken Elisa Banchi Riccardo Velasco Piergiorgio Stevanato W.Eric van de Weg Mario Di Guardo Satish Kumar François Laurens Marco C.A.M.Bink | 2015 | Horticulture Research2015，2，1： | 14 |
| 7 | Solutions for submucosal injection: What to choose and how to do it显示文摘During the past decades, endoscopic resection techniques have gradually improved and gained more importance for the management of premalignant lesions and early cancers. These endoscopic resection techniques can be divided in 3 major groups: snare polipectomy, endoscopic mucosal resection(EMR) and endoscopic submucosal dissection(ESD). The use of submucosal injection is essential for the majority of EMR techniques and is an integral part of ESD,whereas during polipectomy it is not crucial in most cases except to prevent bleeding in large polyps and/or those with large stalks as an alternative to mechanical methods. Injection provides a lifting up effect of the lesion separating it from the muscular layer, thereby reducing thermal injury and the risk of perforation and bleeding while also facilitating en-bloc resection by improving technical feasibility. With this work, we aim to review the most common endoscopic resection techniques and the importance of submucosal injection in each one of them. For that, we present some of the most commonly used submucosal injection solutions, taking into account their advantages and disadvantages. We also discuss, based on current recommendations and our own experience, how and when to preform submucosal injection, depending on lesions features and endoscopic resection technique that′s being used, to assure complete resection and to prevent associated adverse events. Finally, we also present and discuss some new proposed submucosal injection solutions,endoscopic resection techniques and devices that may have a major impact on the future of therapeutic endoscopy. | Rui Castro Diogo Libanio Inês Pita Mário Dinis-Ribeiro | 2019 | World Journal of Gastroenterology2019，25，7： | 13 |

| 9 | Gut-brain connection: The neuroprotective effects of the anti-diabetic drug liraglutide显示文摘Long-acting glucagon-like peptide-1(GLP-1) analogues marketed for type 2 diabetes(T2D) treatment have been showing positive and protective effects in several different tissues, including pancreas, heart or even brain. This gut secreted hormone plays a potent insulinotropic activity and an important role in maintaining glucose homeostasis. Furthermore, growing evidences suggest the occurrence of several commonalities between T2 D and neurodegenerative diseases, insulin resistance being pointed as a main cause for cognitive decline and increased risk to develop dementia. In this regard, it has also been suggested that stimulation of brain insulin signaling may have a protective role against cognitive deficits. As GLP-1 receptors(GLP-1R) are expressed throughout the central nervous system and GLP-1 may cross the blood-brain-barrier, an emerging hypothesis suggests that they may be promising therapeutic targets against brain dysfunctional insulin signaling-related pathologies. Importantly, GLP-1 actions depend not only on the direct effect mediated by its receptor activation, but also on the gut-brain axis involving an exchange of signals between both tissues via the vagal nerve, thereby regulating numerous physiological functions(e.g., energy homeostasis, glucose-dependent insulin secretion, as well as appetite and weight control). Amongst the incretin/GLP-1 mimetics class of anti-T2 D drugs with an increasingly described neuroprotective potential, the already marketed liraglutide emerged as a GLP-1R agonist highly resistant to dipeptidyl peptidase-4 degradation(thereby having an increased half-life) and whose systemic GLP-1R activity is comparable to that of native GLP-1. Importantly, several preclinical studies showed anti-apoptotic, anti-inflammatory, anti-oxidant and neuroprotective effects of liraglutide against T2 D, stroke and Alzheimer disease(AD), whereas several clinical trials, demonstrated some surprising benefits of liraglutide on weight loss, microglia inhibition, behavior and cognition, and in AD biomarkers. Herein, we discuss the GLP-1 action through the gut-brain axis, the hormone's regulation of some autonomic functions and liraglutide's neuroprotective potential. | Emanuel Monteiro Candeias Inês Carolina Sebastio Susana Maria Cardoso Sónia Catarina Correia Cristina Isabel Carvalho Ana Isabel Plácido Maria Sancha Santos Catarina Resende Oliveira Paula Isabel Moreira Ana Isabel Duarte | 2015 | World Journal of Diabetes2015，6，6： | 9 |
| 10 | The results and prognosis of different treatment modalities for solitary metastatic lung tumor from nasopharyngeal carcinoma:a retrospective study of 105 cases显示文摘Background and Objective:Nasopharyngeal carcinoma (NPC) is known for its propensity for distant metastases.Lung metastasis is one of the most important causes of death for patients with NPC.Solitary metastatic lung tumor from NPC is a distinctive group associated with a better survival.This study was to find a more effective treatment modality and prognostic factors for the group.Methods:Clinical data of 105 cases of solitary metastatic lung tumor from NPC were retrospectively analyzed.Survival rate was calculated by the Kaplan-Meier method.The difference of survival between the patients treated by different modalities was evaluated by the log-rank test.The Cox univariate and multivariate analyses of gender, age, pathologic type, stage, adjuvant chemotherapy, evaluation of treatment for NPC, disease-free interval, size of metastatic tumor, pulmonary hilar and/or mediastinal lymph node metastasis, treatment modalities, recurrent distant metastases and/or relapse of NPC were conducted.Results:The local control rate was 53.8% in chemotherapy group, 88.0% in radiotherapy +/-chemotherapy group, and 96.4% in operation +/-chemotherapy group (P<0.01).The most promising progression-free survival (PFS) and overall survival (OS) were obtained with operation +/-chemotherapy and followed by radiotherapy +/-chemotherapy.Both of them showed much better efficacy than chemotherapy (P<0.001).The Cox multivariate analysis showed that recurrent distant metastases and/or relapse of NPC affected the survival (OR=2.087, 95% CI=1.277-3.410, P=0.003).The T stage of NPC, size of metastatic tumor, hilar and/or mediastinal lymph node metastasis, and the treatment modality were independent prognostic factors.Conclusions:Operation +/-chemotherapy and radiotherapy +/-chemotherapy are better treatment of solitary metastatic lung tumor from NPC, which could improve the local control and prolong the PFS and OS.Chemotherapy is recommended for patients with higher T stage of NPC, size of metastatic tumor ≥3 cm, pulmonary hilar and/or mediastinal lymph node metastasis. | Jun Ma1,2, Zhe-Sheng Wen1,2, Peng Lin1,2, Xin Wang1,2, Fang-Yun Xie1,3 1 State Key Laboratory of Oncology in South China, Guangzhou, Guangdong 510060, P.R.China 2 Department of Thoracic Oncology, Sun Yat-sen University Cancer Center, Guangzhou, Guangdong 510060, P.R.China 3 Department of Radiation Oncology, Sun Yat-sen University Cancer Center, Guangzhou, Guangdong 510060, P.R.China Department of Thoracic Surgery, Shanxi Provincial People’s Hospital, Taiyuan, Shanxi 030012, P.R.China | 2010 | Chinese Journal of Cancer2010，29，9： | 9 |
| 11 | Mitochondrial DNA A1555G mutation screening using a testing kit method and its significance in preventing aminoglycoside-related hearing loss显示文摘To report a new screening method for mitochondrial DNA 1555A→G mutation and the results of genotype analysis in 19 maternal inherited deafness pedigrees.

| 12 | Helicobacter pylori and EBV in gastric carcinomas:Methylation status and microsatellite instability显示文摘AIM:To verify the methylation status of CDH1, DAPK, COX2, hMLH1 and CDKN2A genes and to evaluate their association with Helicobacter pylori (H. pylori)-cagA+ and Epstein Barr virus (EBV) infections in gastric adenocarcinomas.METHODS: Methylation-specific PCR (MSP) assay was performed in 89 primary gastric carcinomas (intestinal and diffuse types). Microsatellite instability (MSI) analysis was performed using the BAT26 primer set and PCR products were analyzed with the ABI PRISM 3100 Genetic Analyzer using Genescan 3.7 software (Applied Biosystems). Detection of H. pylori and genotyping were performed by PCR, using specifi c primers for ureaseC and cagA genes. The presence of EBV was assessed by in situ hybridization. Statistical analyses were performed using the χ2 or Fisher's exact test.RESULTS: The most frequent hypermethylated gene was COX-2 (63.5%) followed by DAPK (55.7%), CDH1 (51%), CDKN2A (36%) and hMLH1 (30.3%). Intestinal and diffuse adenocarcinomas showed different methylation profiles and there was an association between methylation of E-CDH1 and H. pylori-cagA+ in the intestinal adenocarcinoma type. MSI was correlated with hMLH1 methylation. There was an inverse correlation between DAPK hypermethylation and MSI.CONCLUSION: We found a strong association between CDH1 methylation and H. pylori-cagA+ in intestinal-type gastric cancer, association of MSI and better prognosis and an heterogeneous COX-2 overexpression. | Adriana Camargo Ferrasi Nídia Alice Pinheiro Silvia Helena Barem Rabenhorst Otávia Luisa Caballero Maria Aparecida Marchesan Rodrigues Fabrício de Carvalho Celso Vieira de Souza Leite Marcia Valéria Pitombeira Ferreira Marcos Aurélio Pessoa Barros Maria Inês de Moura Campos Pardini | 2010 | World Journal of Gastroenterology2010，16，3： | 6 |

| 15 | CT-guided needle biopsy through mandibular area for the diagnosis of nasopharyngeal carcinoma in the parapharyngeal space显示文摘Background and Objective: The primary submucous type of nasopharyngeal carcinoma (NPC) or the recurrent NPC in the parapharyngeal space is difficult to be diagnosed histologically by conventional biopsy because of the obstruction of the surrounding structures. This study was performed to evaluate the needle biopsy approach through the madibular area into the parapharyngeal space under the guidance of computed tomography (CT) for NPC. Methods: Between July 6, 2005 and October 23, 2009, a total of 6 patients were enrolled into the study. Two patients with cervical lymph node metastasis were clinically suspicious of NPC according to their clinical manifestations. However, no cancer cell could be found by repeated nasopharyngeal biopsies followed by histologic examinations. The other 4 patients were diagnosed with recurrent NPCs by magnetic resonance imaging (MRI) or/and positron emission tomography (PET)-CT scan, showing tumors in the parapharyngeal spaces in 3 patients and enlarged retropharyngeal lymph node in 1 patient. The CT-guided puncture was performed through the mandibular skin and the cutting needle biopsy was taken at the parapharyngeal space focus. Results: All the cutting needle biopsies of projected locations have been performed safely. Finally, all the 7 specimens met the requirement of pathologic diagnosis and the cases were all confirmed histologically to be NPCs. The main complication was mild ache at the puncture point. No blood vessel or nerve was injured and no patient needed special treatment. Conclusions: The CT-guided puncture biopsy of the parapharyngeal space through the mandibular area is simple and feasible. It can be an additional option for routine nasopharyngeal biopsy. | Yong Su1,2, Chong Zhao1,2, Wen-Jie Li1,2, Xue-Ying Deng1,3, Rui-Fang Zeng1,2, Nian-Ji Cui1,2, Tai-Xiang Lu1,2 1 State Key Laboratory of Oncology in South China, Guangzhou, Guangdong 510060, P.

| 19 | Clinical scenarios for the use of S100β as a marker of hepatic encephalopathy显示文摘AIM: To evaluate the association between serum concentrations of S100β in patients with cirrhosis and the presence of low grade hepatic encephalopathy(HE).METHODS: This was a cross-sectional study. The population was categorized into four groups healthy subjects, cirrhosis without HE, cirrhosis with covert hepatic encephalopathy(CHE) and cirrhosis with overt HE. Kruskal-Wallis, Mann Whitney's U with Bonferroni adjustment Spearman correlations and area under the ROC were used as appropriate.RESULTS: A total of 61 subjects were included, 46 cirrhotic patients and 15 healthy volunteers. S100β values were different among all groups, and differences remained significant between groups 1 and 2(P < 0.001), and also between groups 2 and 3(P = 0.016), but not between groups 3 and 4. In cirrhotic patients with HE S100β was higher than in patients without HE [0.18(0.14-0.28) ng/m L vs 0.11(0.06-0.14) ng/m L, P < 0.001]. There was a close correlation between serum concentrations of S100β and psychometric hepatic encephalopathy score in patients with cirrhosis without HE compared to the patients with cirrhosis with CHE(r =-0.413, P = 0.019). ROC curve analysis yielded > 0.13 ng/m L as the best cutoff value of S100β for the diagnosis of HE(sensitivity 83.3%, specificity 63.6%).CONCLUSION: Serum concentrations of S100β are higher in patients with cirrhosis than in healthy volunteers, and are further increased in the presence of hepatic encephalopathy. The results suggest that serum biomarkers such as S100β could help in the correct characterization of incipient stages of HE. | Andrés Duarte-Rojo Astrid Ruiz-Margáin Ricardo U Macias-Rodriguez Francisco Javier Cubero José Estradas-Trujillo Rosa Ma Munoz-Fuentes Aldo Torre | 2016 | World Journal of Gastroenterology2016，22，17： | 4 |
| 20 | Outcome in obscure gastrointestinal bleeding after capsule endoscopy显示文摘AIM: To investigate the clinical impact of capsule endoscopy(CE) after an obscure gastrointestinal bleeding(OGIB) episode, focusing on diagnostic work-up, followup and predictive factors of rebleeding. METHODS: Patients who were referred to Hospital del Mar(Barcelona, Spain) between 2007 and 2009 for OGIB who underwent a CE were retrospectively analyzed. Demographic data, current treatment with non-steroid antiinflammtory drugs or anticoagulant drugs, hemoglobin levels, transfusion requirements, previous diagnostic tests for the bleeding episode, as well as CE findings(significant or non-significant), work-up and patient out-comes were analyzed from electronic charts. Variables were compared by χ 2 analysis and Student t test. Risk factors of rebleeding were assessed by Log-rank test, Kaplan-Meier curves and Cox regression model. RESULTS: There were 105 patients [45.7% women, median age of 72 years old(interquartile range 56-79)] and a median follow-up of 326 d(interquartile range 123-641) included in this study. The overall diagnostic yield of CE was 58.1%(55.2% and 63.2%, for patients with occult OGIB and overt OGIB, respectively). In 73 patients(69.5%), OGIB was resolved. Multivariate analysis showed that hemoglobin levels lower than 8 g/dL at diagnosis [hazard ratios(HR) = 2.7, 95%CI: 1.9-6.3], patients aged 70 years and above(HR = 2.1, 95%CI: 1.2-6.1) and significant findings in CE(HR = 2.4, 95%CI: 1.1-5.8) were independent predictors of rebleeding. CONCLUSION: One third of the patients presented with rebleeding after CE; risk factors were hemoglobin levels < 8 g/dL, age ≥ 70 years or the presence of significant lesions. | Alex Caas-Ventura Lucia Márque Xavier Bessa Josep Maria DedeuDepartment of Gastroenterology Hospital del Mar Research Institute Pompeu Fabra University Marc Puigvehí Sílvia Delgado-Aros Ines Ana Ibáez Agustin Seoane Luis Barranco Felipe Bory Montserrat Andreu Begoa González-Suárez | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，11： | 4 |
