1IDO1 in cancer: a Gemini of immune checkpoints显示文摘Indoleamine 2,3-dioxygenase 1(IDO1)is a rate-limiting metabolic enzyme that converts the essential amino acid tryptophan(Trp)into downstream catabolites known as kynurenines.Coincidently,numerous studies have demonstrated that IDO1 is highly expressed in multiple types of human cancer.Preclinical studies have further introduced an interesting paradox:while single-agent treatment with IDO1 enzyme inhibitor has a negligible effect on decreasing the established cancer burden,approaches combining select therapies with IDO1 blockade tend to yield a synergistic benefit against tumor growth and/or animal subject survival.Given the high expression of IDO1 among multiple cancer types along with the lack of monotherapeutic efficacy,these data suggest that there is a more complex mechanism of action than previously appreciated.Similar to the dual faces of the astrological Gemini,we highlight the multiple roles of IDO1 and review its canonical association with IDO1-dependent tryptophan metabolism,as well as documented evidence confirming the dispensability of enzyme activity for its immunosuppressive effects.The gene transcript levels for IDO1 highlight its strong association with T-cell infiltration,but the lack of a universal prognostic significance among all cancer subtypes.Finally,ongoing clinical trials are discussed with consideration of IDO1-targeting strategies that enhance the efficacy of immunotherapy for cancer patients。Lijie Zhai Erik Ladomersky Alicia Lenzen Brenda Nguyen Ricky Patel Kristen L Lauing Meijing Wu Derek A Wainwright 2018Cellular & Molecular Immunology2018,15,5:17
2Renin and angiotensinogen expression and functions in growth and apoptosis of human glioblastoma显示文摘The expression and function in growth and apoptosis of the renin-angiotensin system(RAS)was evaluated inhuman glioblastoma.Renin and angiotensinogen(AGT)mRNAs and proteins were found by in situ hybridisationand immunohistochemistry in glioblastoma cells.Angiotensinogen was present in glioblastoma cystic fluids.Thus,human glioblastoma cells produce renin and AGT and secrete AGT.Human glioblastoma and glioblastoma cellsexpressed renin,AGT,renin receptor,AT(2)and/or AT(1)mRNAs and proteins determined by RT-PCR and/Juillerat-Jeanneret L Celerier J Chapuis Bernasconi C Nguyen G Wostl W Maerki HP Janzer RC Corvol P Gasc JM 2004中国神经肿瘤杂志2004,2,1:8

4基于FRN技术的我国不同地区典型土壤保持措施的有效性评价显示文摘选择中国西南-东北样带4个典型土壤侵蚀区,包括位于长江上游的西昌,黄土高原延安,北方风蚀区的丰宁和东北黑土区的拜泉,应用环境放射性核素(FRN)技术研究了不同土壤保持措施在减少土壤侵蚀、改善土壤质量方面的作用。在西昌,137Cs和210Pbex的测定结果表明,不同植被覆盖结构减少土壤侵蚀的作用为:灌木>有地被物的乔木>草类>无地被物的乔木;在延安,利用137Cs示踪技术对坡地景观的产沙量估算结果表明,梯田和林草地相对于坡耕地产沙量分别减少了49%和80%,林草地的土壤有机质、碱解氮和速效磷含量相对于坡耕地分别增加了255%、198%和18%,梯田土壤有机质、碱解氮和速效磷含量分别增加了121%、103%和162%,而土壤容重分别降低了1.6%和6.4%;在丰宁,对7Be的测定结果表明,与传统耕作方式相比,4年免耕+作物高留茬(50~56cm)和免耕+作物低留茬(25cm)分别使土壤侵蚀速率下降44%和33%;在拜泉,通过137Cs测定结果发现,坡改梯使土壤流侵蚀降低14%,等高耕作使土壤侵蚀量减少了34%。研究结果说明,灌木林覆盖、林草复合结构是控制西南侵蚀山地土壤侵蚀的优选生物配置措施,梯田和林草复合结构在控制黄土高原土壤侵蚀和改善土壤质量方面有重要作用,免耕+高留茬措施是我国北方风蚀区防治土壤侵蚀退化的有效措施,等高耕作应当成为防治东北黑土区土壤侵蚀的关键措施。于寒青 李勇 Nguyen M L Funk R 刘国强 李俊杰 2012核农学报2012,26,2:6
5A Rapid and Cost-Effective Method for Genotyping Genome-Edited Animals:A Heteroduplex Mobility Assay Using Microfluidic Capillary Electrophoresis显示文摘The recent emergence and application of engineered endonucleases have led to the development of genome editing tools capable of rapidly implementing various targeted genome editions in a wide range of species.Moreover,these novel tools have become easier to use and have resulted in a great increase of applications.Whilst gene knockout(KO) or knockin(KI) animal models are relatively easy to achieve,there is a bottleneck in the detection and analysis of these mutations.Although several methods exist to detect these targeted mutations,we developed a heteroduplex mobility assay on an automated microfluidic capillary electrophoresis system named HMA-CE in order to accelerate the genotyping process.The HMA-CE method uses a simple PCR amplification of genomic DNA(gDNA) followed by an automated capillary electrophoresis step which reveals a heteroduplexes(HD) signature for each mutation.This allows efficient discrimination of wild-type and genome-edited animals down to the single base pair level.Vanessa Chenouard Lucas Brusselle Jean-Marie Heslan Séverine Remy Séverine Ménoret Claire Usal Laure-Hélène Ouisse Tuan Huy NGuyen Ignacio Anegon Laurent Tesson 2016Journal of Genetics and Genomics2016,43,5:4
6Use of the Endocuff during routine colonoscopy examination improves adenoma detection: A meta-analysis显示文摘AIM To perform meta-analysis of the use of Endocuff during average risk screening colonoscopy.METHODS Scopus, Cochrane databases, MEDLINE/Pub Med, and CINAHL were searched in April 2016. Abstracts from Digestive Disease Week, United European Gastroenterology, and the American College of Gastroenterology meeting were also searched from 2004-2015. Studies comparing EC-assisted colonoscopy(EAC) to standard colonoscopy, for any indication, were included in the analysis. The analysis was conducted by using the Mantel-Haenszel or DerS imonian and Laird models with the odds ratio(OR) to assess adenoma detection, cecal intubation rate, and complications performed. RESULTS Nine studies(n = 5624 patients) were included in the analysis. Compared to standard colonoscopy, procedures performed with EC had higher frequencies for adenoma(OR = 1.49, 95%CI: 1.23-1.80; P = 0.03), and sessile serrated adenomas detection(OR = 2.34 95%CI: 1.63-3.36; P < 0.001). There was no significant difference in cecal intubation rates between the EACgroup and standard colonoscopy(OR = 1.26, 95%CI: 0.70-2.27, I2 = 0%; P = 0.44). EAC was associated with a higher risk of complications, most commonly being superficial mucosal injury without higher frequency for perforation.CONCLUSION The use of an EC on colonoscopy appears to improve pre-cancerous polyp detection without any difference in cecal intubation rates compared to standard colonoscopy.Matthew Chin William Karnes M Mazen Jamal John G Lee Robert Lee Jason Samarasena Matthew L Bechtold Douglas L Nguyen 2016World Journal of Gastroenterology2016,22,43:4
7Nutritional and health benefits of semi-elemental diets: A comprehensive summary of the literature显示文摘AIM:To critically review and summarize the literature on nutritional and health outcomes of semi-elemental formulations on various nutritionally vulnerable patient populations who are unable to achieve adequate nutrition from standard oral diets.METHODS:We conducted a comprehensive literature search of Pubmed and Embase databases.We manually screened articles that examined nutritional and health outcomes(e.g.,growth,disease activity,gastrointestinal impairment,mortality,and economic impact)among various patient groups receiving semi-elemental diets.This review focused on full-text articles of randomized controlled clinical trials and other intervention studies,but pertinent abstracts and case studies were also included.Results pertaining primarily to tolerance,digestion,and absorption were summarized for each patient population in this systematic review.RESULTS:Results pertaining primarily to tolerance,digestion,and absorption were summarized for each patient population.The efficacy of semi-elemental whey hydrolyzed protein(WHP)diet have been reported in various nutritionally high risk patient populations including-Crohn’s disease,short bowel syndrome,acute and chronic pancreatitis,cerebral palsy,cystic fibrosis,cerebrovascular accidents,human immunodeficiency virus,critically ill,and geriatrics.Collectively,the evidence from the medical literature indicates that feeding with a semi-elemental diet performs as well or better than parenteral or amino acid based diets in terms of toler-ance,digestion,and nutrient assimilation measures across various disease conditions.CONCLUSION:Based on this comprehensive review of the literature,patient populations who have difficulty digesting or absorbing standard diets may be able to achieve improved health and nutritional outcomes through the use of semi-elemental WHP diets.Dominik D Alexander Lauren C Bylsma Laura Elkayam Douglas L Nguyen 2016World Journal of Gastrointestinal Pharmacology and Therapeutics2016,7,2:3
8Outcomes of Roux-en-Y gastric bypass and laparoscopic adjustable gastric banding显示文摘AIM:To evaluate weight loss and surgical outcomes of Roux-en-Y gastric bypass(RYGB)and laparoscopic adjustable gastric band(LAGB).METHODS:Data relating to changes in body mass index(BMI)and procedural complications after RYGB(1995-2009;n=609;116M:493F;42.4±0.4 years)or LAGB(2004-2009;n=686;131M:555F;37.2±0.4years)were extracted from prospective databases.RESULTS:Pre-operative BMI was higher in RYGB than LAGB patients(46.8±7.1 kg/m2vs 40.4±4.2 kg/m2,P<001);more patients with BMI<35 kg/m2underwent LAGB than RYGB(17.1%vs 4.1%,P<0.0001).BMI decrease was greater after RYGB.There were direct relationships between weight loss and pre-operative BMI(P<0.001).Although there was no difference in weight loss between genders during the first 3-year post-surgery,male LAGB patients had greater BMI reduction than females(-8.2±4.3 kg/m2vs-3.9±1.9kg/m2,P=0.02).Peri-operative complications occurred more frequently following RYGB than LAGB(8.0%vs0.5%,P<0.001);majority related to wound infection.LAGB had more long-term complications requiring corrective procedures than RYGB(8.9%vs 2.1%,P<0.001).Conversion to RYGB resulted in greater BMI reduction(-9.5±3.8 kg/m2)compared to removal and replacement of the band(-6.0±3.0 kg/m2).Twelve months post-surgery,fasting glucose,total cholesterol and low density lipoprotein levels were significantly lower with the magnitude of reduction greater in RYGB patients.CONCLUSION:RYGB produces substantially greater weight loss than LAGB.Whilst peri-operative complications are greater after RYGB,long-term complication rate is higher following LAGB.Nam Q Nguyen Philip Game Justin Bessell Tamara L Debreceni Melissa Neo Carly M Burgstad Pennie Taylor Gary A Wittert 2013World Journal of Gastroenterology2013,19,36:3

11Bleeding risk with clopidogrel and percutaneous endoscopic gastrostomy显示文摘AIM To compare bleeding within 48 h in patients undergoing percutaneous endoscopic gastrostomy(PEG) with or without clopidogrel.METHODS After institutional review board approval, a retrospective study involving a single center was conducted on adult patients having PEG(1/08-1/14). Patients were divided into two groups: Clopidogrel group consisting of those patients taking clopidogrel within 5 d of PEG and the non-clopidogrel group including those patients not taking clopidogrel within 5 d of the PEG.RESULTS Three hundred and nineteen PEG patients were found. One hundred and sixty-eight males and 151 females with mean body mass index 28.47 ± 9.75 kg/m2 and mean age 65.03 ± 16.11 years were identified. Thirtythree patients were on clopidogrel prior to PEG with 286 patients not on clopidogrel. No patients in either group developed hematochezia, melena, or hematemesiswithin 48 h of percutaneous endoscopic gastrostomy(PEG). No statistical differences were observed between the two groups with 48 h for hemoglobin decrease of > 2 g/dL(2 vs 5 patients; P = 0.16), blood transfusions(2 vs 7 patients; P = 0.24), and repeat endoscopy for possible gastrointestinal bleeding(no patients in either group). CONCLUSION Based on the results, no significant post-procedure bleeding was observed in patients undergoing PEG with recent use of clopidogrel.Umair Sohail Chela Harleen Amin O Mahdi Murtaza Arif Douglas L Nguyen Matthew L Bechtold 2016World Journal of Gastrointestinal Endoscopy2016,8,16:2
