2Colon cancer-associated B2 Escherichia coli colonize gut mucosa and promote cell proliferation显示文摘AIM:To provide further insight into the characterization of mucosa-associated Escherichia coli(E.coli)isolated from the colonic mucosa of cancer patients.METHODS:Phylogroups and the presence of cyclomodulin-encoding genes of mucosa-associated E.coli from colon cancer and diverticulosis specimens weredetermined by PCR.Adhesion and invasion experiments were performed with I-407 intestinal epithelial cells using gentamicin protection assay.Carcinoembryonic antigen-related cell adhesion molecule 6(CEACAM6)expression in T84 intestinal epithelial cells was measured by enzyme-linked immunosorbent assay and by Western Blot.Gut colonization,inflammation and procarcinogenic potential were assessed in a chronic infection model using CEABAC10 transgenic mice.Cell proliferation was analyzed by real-time mRNA quantification of PCNA and immunohistochemistry staining of Ki67.RESULTS:Analysis of mucosa-associated E.coli from colon cancer and diverticulosis specimens showed that whatever the origin of the E.coli strains,86%of cyclomodulin-positive E.coli belonged to B2 phylogroup and most harbored polyketide synthase(pks)island,which encodes colibactin,and/or cytotoxic necrotizing factor(cnf)genes.In vitro assays using I-407 intestinal epithelial cells revealed that mucosa-associated B2 E.coli strains were poorly adherent and invasive.However,mucosa-associated B2 E.coli similarly to Crohn’s disease-associated E.coli are able to induce CEACAM6expression in T84 intestinal epithelial cells.In addition,in vivo experiments using a chronic infection model of CEACAM6 expressing mice showed that B2 E.coli strain11G5 isolated from colon cancer is able to highly persist in the gut,and to induce colon inflammation,epithelial damages and cell proliferation.CONCLUSION:In conclusion,these data bring new insights into the ability of E.coli isolated from patients with colon cancer to establish persistent colonization,exacerbate inflammation and trigger carcinogenesis.Jennifer Raisch Emmanuel Buc Mathilde Bonnet Pierre Sauvanet Emilie Vazeille Amélie de Vallée Pierre Déchelotte Claude Darcha Denis Pezet Richard Bonnet Marie-Agnès Bringer Arlette Darfeuille-Michaud 2014World Journal of Gastroenterology2014,20,21:12
3Role of CARD15,DLG5 and OCTN genes polymorphisms in children with inflammatory bowel diseases显示文摘AIM: To investigate the contribution of variants of CARD15, OCTN1/2 and DLG5 genes in disease predispo- sition and phenotypes in a large Italian cohort of pediatric patients with inflammatory bowel diseases (IBD). METHODS: Two hundred patients with Crohn’s disease (CD), 186 ulcerative colitis (UC) patients, 434 par- ents (217 trios), and 347 healthy controls (HC) were studied. Polymorphisms of the three major variants of CARD15, 1672C/T and -207G/C SNPs for OCTN genes, IGR2096a_1 and IGR2198a_1 SNPs for the IBD5 locus, and 113G/A variant of the DLG5 gene were evaluated. Potential correlations with clinical sub-phenotypes were investigated. RESULTS: Polymorphisms of CARD15 were significantly associated with CD, and at least one variant was found in 38% of patients (15% in HC, OR = 2.7, P < 0.001). Homozygosis for both OCTN1/2 variants was more com- mon in CD patients (1672TT 24%, -207CC 29%) than in HC (16% and 21%, respectively; P = 0.03), with an in- creased frequency of the TC haplotype (44.8% vs 38.3% in HC, P = 0.04). No association with the DLG5 variant was found. CD carriers of OCTN1/2 and DLG5 variants more frequently had penetrating disease (P = 0.04 and P = 0.01), while carriers of CARD15 more frequently had ileal localization (P = 0.03). No gene-gene interaction was found. In UC patients, the TC haplotype was morefrequent (45.4%, P = 0.03), but no genotype/phenotype correlation was observed. CONCLUSION: Polymorphisms of CARD15 and OCTN genes, but not DLG5 are associated with pediatric on- set of CD. Polymorphisms of CARD15, OCTN, and DLG5 genes exert a weak influence on CD phenotype.S Cucchiara A Latiano O Palmieri AM Staiano R D'Incà G Guariso G Vieni V Rutigliano O Borrelli MR Valvano V Annese 2007World Journal of Gastroenterology2007,13,8:9

5D-二聚体预测稳定型冠状动脉性心脏病患者的长期病因特异性死亡率、心血管事件和癌症显示文摘交联纤维蛋白的降解产物D-二聚体是高凝状态和血栓形成事件的标志。D-二聚体水平中度升高与血管疾病患者静脉和动脉事件的风险相关。在缺血性疾病长期普伐他汀干预(long-term intervention with pravastatin in ischemic disease,LIPID)试验中,研究者在存在其他危险因素的背景下,评估了D-二聚体水平在预测长期血管转归、病因特异性死亡率和新发癌症中的作用。刘青 叶鹏 Simes J Robledo KP White HD Espinoza D Stewart RA Sullivan DR Zeller T Hague W Nestel PJ Glasziou PP Keech AC Elliott J Blankenberg S Tonkin AM LIPID study investigators 2018中华高血压杂志2018,26,3:6
6Role of ischaemic preconditioning in liver regeneration following major liver resection and transplantation显示文摘Liver ischaemic preconditioning (IPC) is known to protect the liver from the detrimental effects of ischaemic-reperfusion injury (IRI), which contributes significantly to the morbidity and mortality following major liver surgery. Recent studies have focused on the role of IPC in liver regeneration, the precise mechanism of which are not completely understood. This review discusses the current understanding of the mechanism of liver regeneration and the role of IPC in this setting. Relevant articles were reviewed from the published literature using the Medline database.

8非甾体抗炎药应用中,环氧合酶2、不对称二甲基精氨酸与心血管危害的关系显示文摘已有大规模、安慰剂对照试验确定了非甾体类抗炎药(nonsteroidal anti—inflammatory drugs,NSAIDs)具有心血管危害性:这归因于环氧合酶2(cyclooxygenase,COX-2)的心脏保护产物受到抑制,尤其是前列环素(prostacyclin,PG12)。NSAID降低心脏保护作用的另一种机制可能是通过增强肾脏中甲基精氨酸的形成来限制一氧化氮在整个脉管系统中的作用。Ricciotti E Castro C Tang SY Briggs WTE West JA Malik D Rhoades SD Meng H Li X Lahens NF Sparks JA Karlson EW Weljie AM Griffin JL FitzGerald GA6 刘青 叶鹏 2018中华高血压杂志2018,26,9:3
9重组脊髓灰质炎病毒用于治疗复发胶质母细胞瘤(英文)显示文摘Background The prognosis of patients with recurrent World Health Organization(WHO)grade IV malignant glioma is dismal,and there is currently no effective therapy.We conducted a dose-finding and toxicity study in this population of patients,evaluating convection-enhanced,intratumoral delivery of the recombinant nonpathogenic polio-rhinovirus chimera(PVSRIPO).PVSRIPO recognizes the poliovirus receptor CD155,which is widely expressed in neoplastic cells of solid tumors and in major components of the tumor microenvironment.Methods We enrolled consecutive adult patients who had recurrent supratentorial WHO grade IV malignant glioma,confirmed on histopathological testing,with measurable disease(contrast-enhancing tumor of≥1 cm and≤5.5 cm in the greatest dimension).The study evaluated seven doses,ranging between 107 and 1010 50%tissue-culture infectious doses(TCID50),first in a dose-escalation phase and then in a dose-expansion phase.Results From May 2012 through May 2017,a total of 61 patients were enrolled and received a dose of PVSRIPO.Dose level-1(5.0×107TCID50)was identified as the phase 2 dose.One dose-limiting toxic effect was observed;a patient in whom dose level 5(1010TCID50)was administered had a grade 4 intracranial hemorrhage immediately after the catheter was removed.To mitigate locoregional inflammation of the infused tumor with prolonged glucocorticoid use,dose level 5 was deescalated to reach the phase 2 dose.In the dose-expansion phase,19%of the patients had a PVSRIPO-related adverse event of grade 3 or higher.Overall survival among the patients who received PVSRIPO reached a plateau of 21%(95%confidence interval,11 to 33)at 24 months that was sustained at 36 months.Conclusions Intratumoral infusion of PVSRIPO in patients with recurrent WHO grade IV malignant glioma confirmed the absence of neurovirulent potential.The survival rate among patients who receivedPVSRIPO immunotherapy was higher at 24 and 36 months than the rate among historical controls.Desjardins A Gromeier M Herndon JE 2nd Beaubier N Bolognesi DP Friedman AH Friedman HS McSherry F Muscat AM Nair S Peters KB Randazzo D Sampson JH Vlahovic G Harrison WT McLendon RE Ashley D Bigner DD 2018中华神经外科疾病研究杂志2018,17,4:2
