| 1 | Interstitial cells of Cajal in the gut-A gastroenterologist’s point of view显示文摘Alterations of normal function of interstitial cells of Cajal (ICC) are reported in many intestinal disorders. Diagnosis of their involvement is rare (infrequent), but necessary to propose a specifi c treatment. This article reviews the place of ICC in the pathogenesis of achalasia, gastroesophageal reflux disease, infantile hypertrophic pyloric stenosis, chronic intestinal pseudoobstruction and slow transit constipation. Moreover we discuss the role of the Cajal cells in the development of stromal tumors of the gastrointestinal tract. | Lucian M Negreanu Philippe Assor Bogdan Mateescu Catalin Cirstoiu | 2008 | World Journal of Gastroenterology2008，14，41： | 27 |
| 2 | Noninvasive investigations for non alcoholic fatty liver disease and liver fi brosis显示文摘Non-alcoholic fatty liver disease (NAFLD) includes a spectrum of diseases that have insulin resistance in common and are associated with metabolic conditions such as obesity, type 2 diabetes mellitus, and dyslipidemia. NAFLD ranges from simple liver steatosis, which follows a benign course, to nonalcoholic steatohepatitis (NASH), a more severe entity, with necroinflmmation and f ibrosis, which can progress to cryptogenic cirrhosis and end-stage liver disease. Liver biopsy remains the gold standard for evaluating the degree of hepatic necroinflammation and f ibrosis; however, several noninvasive investigations, such as serum biomarkers, have been developed to establish the diagnosis and also to evaluate treatment response. These markers are currently neither available in all centers nor validated in extensive studies. Examples include high-sensitivity C reactive protein and plasma pentraxin 3, which are associated with extensive liver f ibrosis in NASH. Interleukin-6 correlates with inflammation, and cytokeratin-18 represents a marker of hepatocyte apoptosis (prominent in NASH and absent in simple steatosis). Tissue polypep-tide specif ic antigen seems to have a clinical utility in the follow-up of obese patients with NASH. | Carmen Fierbinteanu-Braticevici Ion Dina Ana Petrisor Laura Tribus Lucian Negreanu Catalin Carstoiu | 2010 | World Journal of Gastroenterology2010，16，38： | 21 |
| 3 | San copolymer membranes with ion exchangers for Cu(Ⅱ)removal from synthetic wastewater by electrodialysis显示文摘Heterogeneous membranes were obtained by using styrene-acrylonitrile copolymer(SAN)blends with low content of ion-exchanger particles(5 wt.%). The membranes obtained by phase inversion were used for the removal of copper ions from synthetic wastewater solutions by electrodialytic separation. The electrodialysis was conducted in a three cell unit, without electrolyte recirculation. The process, under potentiostatic or galvanostatic control, was followed by p H and conductivity measurements in the solution. The electrodialytic performance,evaluated in terms of extraction removal degree(rd) of copper ions, was better under potentiostatic control then by the galvanostatic one and the highest(over 70%) was attained at8 V. The membrane efficiency at small ion-exchanger load was explained by the migration of resin particles toward the pores surface during the phase inversion. The prepared membranes were characterized by various techniques i.e. optical microscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis and differential thermal analysis and contact angle measurements. | Simona Caprarescu Mihai Cosmin Corobea Violeta Purcar Catalin Ilie Spataru Raluca Ianchis Gabriel Vasilievici Zina Vuluga | 2015 | Journal of Environmental Sciences2015，27，9： | 8 |
| 4 | Angiogenesis of hepatocellular carcinoma: An immunohistochemistry study显示文摘BACKGROUND Although hepatocellular carcinoma(HCC) is one of the most vascular solid tumors, antiangiogenic therapy has not induced the expected results.AIM To uncover immunohistochemical(IHC) aspects of angiogenesis in HCC.METHODS A retrospective cohort study was performed and 50 cases of HCC were randomly selected. The angiogenesis particularities were evaluated based on the IHC markers Cyclooxygenase-2(COX-2), vascular endothelial growth factor(VEGF) A and the endothelial area(EA) was counted using the antibodies CD31 and CD105.RESULTS The angiogenic phenotype evaluated with VEGF-A was more expressed in small tumors without vascular invasion(pT1), whereas COX-2 was rather expressed in dedifferentiated tumors developed in non-cirrhotic liver. The CD31-related EA value decreased in parallel with increasing COX-2 intensity but was higher in HCC cases developed in patients with cirrhosis. The CD105-related EA was higher in tumors developed in patients without associated hepatitis.CONCLUSION In patients with HCC developed in cirrhosis, the newly formed vessels are rather immature and their genesis is mediated via VEGF. In patients with non-cirrhotic liver, COX-2 intensity and number of mature neoformed vessels increases in parallel with HCC dedifferentiation. | Decebal Fodor Ioan Jung Sabin Turdean Catalin Satala Simona Gurzu | 2019 | World Journal of Hepatology2019，11，3： | 6 |
| 5 | Pseudomembranous colitis associated with a triple therapy for Helicobacter pylori eradication显示文摘Helicobacter pylori(H.pylori)is one of the most common chronic bacterial infections in humans,affecting half of world’s population.Therapy for H.pylori infection has proven to be both effective and safe.The oneweek triple therapy including proton pump inhibitor,clarithromycin,and amoxicillin or metronidazole is still recommended as a first-line treatment to eradicate H.pylori infection in countries with low clarithromycin resistance.Generally,this therapy is well-tolerated,with only a few and usually minor side effects.However,rare but severe adverse effects such as pseudomembranous colitis have been reported,Clostridium difficile(C.difficile)infection being the main causative factor in all cases.We report the cases of two women who developed pseudomembranous colitis after a 1-wk triple therapy consisting of pantoprazole 20 mg bid,clarithromycin 500 mg bid,and amoxicillin 1 g bid to eradicate H.pylori infection.A limited colonoscopy showed typical appearance of pseudomembranous colitis,and the stool test for C.difficile toxins was positive.Rapid resolution of symptoms and negative C.difficile toxins were obtained in both patients with oral vancomycin.No relapse occurred during a four and eleven-month,respectively,follow up.These cases suggest that physicians should have a high index of suspicion for pseudomembranous colitis when evaluate patients with diarrhea following H.pylori eradication therapy. | Anca Trifan Irina Girleanu Camelia Cojocariu Catalin Sfarti Ana Maria Singeap Carmen Dorobat Lucia Grigore Carol Stanciu | 2013 | World Journal of Gastroenterology2013，19，42： | 5 |
| 6 | Solid solution or amorphous phase formation in TiZr-based ternary to quinternary multi-principal-element films显示文摘TiZr-based multicomponent metallic films composed of 3–5 constituents with almost equal atomic concentrations were prepared by cosputtering of pure metallic targets in an Ar atmosphere.X-ray diffraction was employed to determine phase composition,crystalline structure,lattice parameters,texture and crystallite size of the deposited films.The deposited films exhibited only solid solution(fcc,bcc or hcp) or amorphous phases,no intermetallic components being detected.It was found that the hcp structure was stabilized by the presence of Hf or Y,bcc by Nb or Al and fcc by Cu.For the investigated films,the atomic size difference,mixing enthalpy,mixing entropy,Gibbs free energy of mixing and the electronegativity difference for solid solution and amorphous phases were calculated based on Miedema's approach of the regular solution model.It was shown that the atomic size difference and the ratio between the Gibbs free energies of mixing of the solid solution and amorphous phases were the most significant parameters controlling the film crystallinity. | Mariana Braic Viorel Braic Alina Vladescu Catalin N.Zoita Mihai Balaceanu | 2014 | Progress in Natural Science:Materials International2014，24，4： | 4 |
| 7 | Split-dose or hybrid nonsteroidal anti-inflammatory drugs and Nacetylcysteine therapy for prevention of post-retrograde cholangiopancreatography pancreatitis显示文摘BACKGROUND Despite significant technical and training improvements, the incidence of postendoscopic retrograde cholangiopancreatography(ERCP) pancreatitis(PEP) has not significantly dropped. Although many studies have evaluated the efficacy of various agents, e.g. nonsteroidal anti-inflammatory drugs, octreotide,antioxidants, administered via various dosages, routes(oral, intrarectal or parenteral), and schedules(before or after the procedure), the results have been conflicting.AIM To evaluate efficacy of three pharmacologic prophylactic methods for prevention of PEP.METHODS In this prospective, single-center randomized trial, patients who underwent firsttime ERCP for choledocholithiasis were randomly assigned to three groups. The first group received 600 mg N-acetylcysteine 15 min prior to ERCP, and perrectum administration of 50 mg indomethacin both prior to and after completion of the ERCP. The second group was administered only the 50 mg indomethacin per-rectum both prior to and after the ERCP. The third group was administeredper-rectum 100 mg indomethacin only after the ERCP, representing the control group given the guideline-recommended regimen. The primary end-point was PEP prevention.RESULTS Among the total 211 patients evaluated during the study, 186 fulfilled the inclusion criteria and completed the protocol. The percentages of patients who developed PEP in each of the three groups were not significantly different(χ2 =2.793, P = 0.247). Among the acute PEP cases, for all groups, 14 patients developed mild pancreatitis(77.77%) and 4 moderate. No severe cases of PEP occurred, and in all PEP cases the resolution was favorable. No adverse events related to the medications(digestive hemorrhage, rectal irritation, or allergies)occurred.CONCLUSION The efficacies of split-dose indomethacin and combined administration(Nacetylcysteine with indomethacin) for preventing PEP were similar to that of the standard regimen. | Laura Pavel Gheorghe Gh Balan Alexandra Nicorescu Georgiana Emmanuela Gilca-Blanariu Catalin Sfarti Stefan Chiriac Smaranda Diaconescu Vasile Liviu Drug Gheorghe Balan Gabriela Stefanescu | 2019 | World Journal of Clinical Cases2019，7，3： | 3 |
| 8 | Preparation,characterization and catalytic behavior of Pt-Cu nanoparticles in methane combustion显示文摘Fine and well dispersed Pt-Cu bimetallic nanoparticles stabilized by polyvinyl pyrrolidone (PVP) were synthesized by alkaline polyol method. The molar ratio of Pt to Cu was 1 : 1. Further, the Pt-Cu bimetallic nanoparticles were supported on alumina and their catalytic behavior in methane combustion was investigated. The as-prepared as well as the supported Pt-Cu nanoparticles were characterized by transmission elec-tron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), fractal analysis and X-ray diffraction (XRD). The dependence of methane combustion on the morphology and surface composition of Pt-Cu nanoparticles was analyzed based on the experimental results. | Florica Papa Catalin Negrila Gianina Dobrescu Akane Miyazaki Ioan Balint | 2011 | Journal of Natural Gas Chemistry2011，20，5： | 3 |
| 9 | Robot-assisted surgery for gastric cancer显示文摘Minimally invasive surgery for gastric cancer is a rela-tively new research field, with convincing results mostly stemming from Asian countries. The use of the robotic surgery platform, thus far assessed as a safe procedure, which is also easier to learn, sets the background for a wider spread of minimally invasive technique in the treatment of gastric cancer. This review will cover the literature published so far, analyzing the pros and cons of robotic surgery and highlighting the remaining study questions. | livia procopiuc stefan tudor mircea manuc mircea diculescu catalin vasilescu | 2016 | World Journal of Gastrointestinal Oncology2016，8，1： | 2 |
