1Signet-ring cell carcinoma of the stomach: Impact on prognosis and specific therapeutic challenge显示文摘While the incidence of gastric cancer has decreased worldwide in recent decades,the incidence of signetring cell carcinoma(SRCC) is rising. SRCC has a specific epidemiology and oncogenesis and has two forms: early gastric cancer,which can be resected endoscopically in some cases and which has a better outcome than non-SRCC,and advanced gastric cancer,which is generally thought to have a worse prognosis and lower chemosensitivity than non-SRCC. However,the prognosis of SRCC and its chemosensitivity with specific regimens are still controversial as SRCC is not specifically identified in most studies and its poor prognosis may be due to its more advanced stage. It therefore remains unclear if a specific therapeutic strategy is justified,as the benefit of perioperative chemotherapy and the value of taxanebased chemotherapy are unclear. In this review we analyze recent data on the epidemiology,oncogenesis,prognosis and specific therapeutic strategies in both early and advanced SRCC of the stomach and in hereditary diffuse gastric cancer.Simon Pernot Thibault Voron Geraldine Perkins Christine Lagorce-Pages Anne Berger Julien Taieb 2015World Journal of Gastroenterology2015,21,40:30
2Colorectal cancer and immunity:what we know and perspectives显示文摘Strong evidence supports the concept of immunosurveillance and immunoediting in colorectal cancer.In particular,the density of T CD8+and CD45+lymphocyte infiltration was recently shown to have a better prognostic value than the classic tumor node metastasis classification factor.Other immune subsets,as macrophages,natural killer cells or unconventionnal lymphocytes,seem to play an important role.Induction of regulatory T cells(Tregs)or immunosuppressive molecules such as PD-1 or CTLA-4 and downregulation of antigen-presenting molecules are major escape mechanisms to antitumor immune response.The development of these mechanisms is a major obstacle to the establishment of an effective immune response,but also to the use of immunotherapy.Although im-munotherapy is not yet routinely used in colorectal cancer,we now know that most treatments used(chemotherapy and biotherapy)have immunomodulatory effects,such as induction of immunogenic cell death by chemotherapy,inhibition of immunosuppression by antiangiogenic agents,and antibody-dependent cytotoxicity induced by cetuximab.Finally,many immunotherapy strategies are being developed and tested in phaseⅠtoⅢclinical trials.The most promising strategies are boosting the immune system with cytokines,inhibition of immunoregulatory checkpoints,vaccination with vectorized antigens,and adoptive cell therapy.Comprehension of antitumor immune response and combination of the different approaches of immunotherapy may allow the use of effective immunotherapy for treatment of colorectal cancer in the near future.Simon Pernot Magali Terme Thibault Voron Orianne Colussi Elie Marcheteau Eric Tartour Julien Taieb 2014World Journal of Gastroenterology2014,20,14:19

5Neoadjuvant sorafenib combined with gemcitabine plus oxaliplatin in advanced hepatocellular carcinoma显示文摘This paper reports the first case of a patient with hepatocellular carcinoma with lymph node metastasis treated by sorafenib combined with gemcitabine plus oxaliplatin,with a partial response and normalization of α fetoprotein,which allowed curative surgery.The potential synergy between these three drugs needs to be confirmed,and is currently being investigated in a randomized phase Ⅱ trial.Nicolas Williet Olivier Dubreuil Tarek Boussaha Isabelle Trouilloud Bruno Landi Martin Housset Muriel Botti Philippe Rougier Jacques Belghiti Julien Taieb 2011World Journal of Gastroenterology2011,17,17:8
6我国四级政府创新政策体系下的企业响应策略与行动:基于扎根理论的多案例研究显示文摘企业如何响应创新政策是政府创新政策能否发挥作用的关键。本文以我国6家高新技术企业为研究对象,采用多案例研究方法和扎根理论来探索科技企业对我国中央、省、市、区/县四级政府创新政策及其体系的响应机制,并构建了'认知-策略-行动'理论模型。研究发现,企业不仅会从政策文本中看到政策资源,还能从四级政府创新政策的竞争体系中感知到政治压力和市场压力,并识别出产业信息。并且,不同企业对不同层级政府创新政策的认知水平不同,这种认知上的差异使得企业对不同层级政府创新政策采取不同的响应策略。田志龙 陈丽玲 Taieb Hafsi 顾佳林 2021管理评论2021,33,12:5
7Cytokine and apoptosis gene polymorphisms influence the outcome of hepatitis C virus infection显示文摘BACKGROUND:Hepatitis C virus (HCV) infection is thought to be chronic and the factors leading to viral clearance or persistence are poorly understood.This study was undertaken to investigate the possibility of a significant relationship between the spontaneous clearance or the persistence of hepatitis C virus (HCV) infection and cytokine and apoptosis gene polymorphisms in Tunisian patients on hemodialysis.METHODS:Polymorphisms of the genes IL-1 (-889 IL-1α,-511 and +3954 IL-1β,IL-1Ra),IL-18 (-137 and-607),IL-12 (-1188) and Apo1/Fas (-670) were determined by PCR-RFLP,PCR-SSP and PCR-VNTR in 100 healthy blood donors and 100 patients infected with HCV and undergoing hemodialysis.The patients were classified into two groups:G1 consisted of 76 active chronic hepatitis patients (positive for HCV RNA) and G2 consisted of 24 hemodialysed patients who spontaneously eliminated the virus (negative for HCV RNA).RESULTS:The frequency of genotype association [-137GC/-607CA] IL-18 was higher in G2 (41.7%) than in G1 (15.8%) (P=0.008;OR=0.26;95% CI,0.10-0.73).We also found a higher frequency of the AA genotype of the Apo1/Fas gene in G2 (41.6%) than in G1 (17.5%) (P=0.026;OR=3.49;95% CI,1.13-10.69).Adjustment for known covariate factors (age,gender and genotype) confirmed these univariate findings and revealed that the genotype association GC-CA of the (-137 and-607) IL-18 gene and the AA genotype of the Apo1/Fas gene were associated with the clearance of HCV (P=0.041 and 0.017,respectively).CONCLUSION:The two genotypes GC-CA of the (-137 and-607) IL-18 polymorphism and the AA genotype of the Apo1/Fas gene influence the outcome of HCV infection in Tunisian patients on hemodialysis.Leila Ksiaa Cheikhrouhou Imen Sfar Hajer Aounallah-Skhiri Houda Aouadi Salwa Jendoubi-Ayed Taieb Ben Abdallah Khaled Ayed Yousr Lakhoua-Gorgi 2011Hepatobiliary & Pancreatic Diseases International2011,10,3:4

9Natural evolution of hepatitis C virus infection in hemodialysis Tunisian patients and CTLA-4 SNP's显示文摘AIM: To analyze the polymorphisms of CTLA-4 gene involved in the response against hepatitis C virus(HCV) infection.METHODS: We recruited 500 hemodialysed patients from several hemodialysis centers, all HCV-antibody positive, spread over different regions of Tunisia, as part of a national survey in 2008 conducted in the laboratory of immunology at the Charles Nicolle hospital Tunisia, classified into two groups G1(PCR+) and G2(PCR-) according to the presence or absence of viral RNA. Of these patients, 307 were followed prospectively on a viral molecular level over a period from 2002 to 2008, divided into two groups based on the persistence and viral clearance. PCR-RFLP was performed for the analysis of SNPs(+49) A/G and(+6230) G/A CTLA-4 for these 500 patients and 358 healthy controls.RESULTS: Analysis of clinical and virological charac-teristics of our cohort suggests a nosocomial infection in our hemodialysed patients with transfusion history as a primary risk factor and a predominance of genotype 1b. The haplotype analysis revealed an increase of frequencies of GG(+49)/(CT60) CTLA-4 in the entire patients group compared to controls(P = 0.0036 and OR = 1.42; 95%CI: 1.12-1.79, respectively). This haplotype is therefore associated with susceptibility to HCV infection. CONCLUSION: Our study suggests a possible role of CTLA-4 polymorphisms in the outcome of HCV infection in the Tunisian hemodialysed population.Leila Ksiaa Cheikhrouhou Yousr Lakhoua-Gorgi Imen Sfar Salwa Jendoubi-Ayed Houda Aouadi Mouna Makhlouf Khaled Ayed Taieb Ben Abdallah 2015World Journal of Gastroenterology2015,21,35:2
