| 1 | Tight junctions in inflammatory bowel diseases and inflammatory bowel disease associated colorectal cancer显示文摘Inflammatory bowel diseases are characterised by inflammation that compromises the integrity of the epithelial barrier. The intestinal epithelium is not only a static barrier but has evolved complex mechanisms to control and regulate bacterial interactions with the mucosal surface. Apical tight junction proteins are critical in the maintenance of epithelial barrier function and control of paracellular permeability. The characterisation of alterations in tight junction proteins as key players in epithelial barrier function in inflammatory bowel diseases is rapidly enhancing our understanding of critical mechanisms in disease pathogenesis as well as novel therapeutic opportunities. Here we give an overview of recent literature focusing on the role of tight junction proteins, in particular claudins, in inflammatory bowel diseases and inflammatory bowel disease associated colorectal cancer. | Jonathan Landy Emma Ronde Nick English Sue K Clark Ailsa L Hart Stella C Knight Paul J Ciclitira Hafid Omar Al-Hassi | 2016 | World Journal of Gastroenterology2016，22，11： | 39 |
| 2 | Reduction of Cancer Risk With an Oral Supplement of Selenium显示文摘The hypothesis that a dietary Supplement of selenium (Se) may reduce cancer risk was tested experimetally in humans. Patients with histories of basal/squarnous cell carcinomas of the skin were assigned randomly in double-blind fashion to dally oral supplements of either Seenriched yeast (200 μg Se/day), or a low-Se yeast placebo. A total of 1312 patients recruited in 1983-1990 were followed with regular dermatologic examinations through 1993 for a total of 8269 person-years of observation. Skin cancer diagnoses were confirmed histologically.Plasma Se concentration was determined at 6-12 months intervals. All deaths and patient-reported illnesses were recorded; reported cancers were confirmed and documented by consultation with the patient medical care providers. The results indicate that Se did not significantly affect the primary endpoints: incidences of recurrent basal/squarnous cell carcinomas of the skin. However, Setreatment was associated with reductions in several secondary endpoints:total mortality, mortality from all cancers combined, as well as the incidence of all cancers combined, lung cancer, colorectal cancer and prostate cancer. The consistencies of these associations over time, between study clinics and for the leading cancer sltes strongly suggests benefits of Se-supplementation for this cohort of patients, supporting the hypopthesis that supplemental Se can reduce cancer risk. Although Se did no shown protective effects against nonmelanoma skin cancers, the suggested reductions in risks to other frequent cancers demand further evaluation in well controlled cliflical intervention | G·F·COMBSJR L·C·CLARK 等 | 1997 | Biomedical and Environmental Sciences1997，10，2： | 21 |
| 3 | Passive expansion of sub-maximally dilated transjugular intrahepatic portosystemic shunts and assessment of clinical outcomes显示文摘AIM To assess for passive expansion of sub-maximally dilated transjugular intrahepatic portosystemic shunts(TIPS) and compare outcomes with maximally dilated TIPS.METHODS Polytetrafluoroethylene covered TIPS(Viatorr) from July 2002 to December 2013 were retrospectively reviewed at two hospitals in a single institution. Two hundred and thirty patients had TIPS maximally dilated to 10 mm(m TIPS), while 43 patients who were at increased risk for hepatic encephalopathy(HE), based on clinical evaluation or low pre-TIPS portosystemic gradient(PSG), had 10 mm TIPS sub-maximally dilated to 8 mm(sm TIPS). Group characteristics(age, gender, Model for End-Stage Liver Disease score, post-TIPS PSG and clinical outcomes were compared between groups, including clinical success(ascites or varices), primary patency,primary assisted patency, and severe post-TIPS HE. A subset of fourteen patients with sm TIPS underwent follow-up computed tomography imaging after TIPS creation, and were grouped based on time of imaging(< 6 mo and > 6 mo). Change in diameter and crosssectional area were measured with 3D imaging software to evaluate for passive expansion.RESULTS Patient characteristics were similar between the sm TIPS and m TIPS groups, except for pre-TIPS portosystemic gradient, which was lower in the sm TIPS group(19.4 mm Hg ± 6.8 vs 22.4 mm Hg ± 7.1, P = 0.01). Primary patency and primary assisted patency between sm TIPS and m TIPS was not significantly different(P = 0.64 and 0.55, respectively). Four of the 55 patients(7%) with sm TIPS required TIPS reduction for severe refractory HE, while this occurred in 6 of the 218 patients(3%) with m TIPS(P = 0.12). For the 14 patients with follow-up computed tomography(CT) imaging, the median imaging follow-up was 373 d. There was an increase in median TIPS diameter, median percent diameter change, median area, and median percent area change in patients with CT follow-up greater than 6 mo after TIPS placement compared to follow-up within 6 mo(8.45 mm, 5.58%, 56.04 mm^2, and 11.48%, respectively, P = 0.01).CONCLUSION Passive expansion of sm TIPS does occur but clinical outcomes of sm TIPS and m TIPS were similar. Sub-maximal dilation can prevent complications related to overshunting in select patients. | Michael C Hsu Charles N Weber S William Stavropoulos Timothy W Clark Scott O Trerotola Richard D Shlansky Goldberg Michael C Soulen Gregory J Nadolski | 2017 | World Journal of Hepatology2017，9，12： | 11 |
| 4 | Upper esophageal sphincter abnormalities are strongly predictive of treatment response in patients with achalasia显示文摘AIM: To investigate the relationship between upper esophageal sphincter abnormalities achalasia treatment METHODS: We performed a retrospective study of 41 consecutive patients referred for high resolution esophageal manometry with a final manometric diagnosis of achalasia. Patients were sub-divided by presence or absence of Upper esophageal sphincter(UES) abnormality, and clinical and manometric profiles were compared.Correlation between UES abnormality and sub-type(i.e.,hypertensive, hypotensive or impaired relaxation) and a number of variables, including qualitative treatment response, achalasia sub-type, co-morbid medical illness,psychiatric illness, surgical history, dominant presentingsymptom, treatment type, age and gender were also evaluated.RESULTS: Among all 41 patients, 24(58.54%) had a UES abnormality present. There were no significant differences between the groups in terms of age, gender or any other clinical or demographic profiles. Among those with UES abnormalities, the majority were either hypertensive(41.67%) or had impaired relaxation(37.5%) as compared to hypotensive(20.83%), although this did not reach statistical significance(P = 0.42). There was no specific association between treatment response and treatment type received; however, there was a significant association between UES abnormalities and treatment response. In patients with achalasia and concomitant UES abnormalities, 87.5% had poor treatment response, while only 12.5% had favorable response. In contrast, in patients with achalasia and no UES abnormalities, the majority(78.57%) had good treatment response, as compared to 21.43% with poor treatment response(P = 0.0001). After controlling for achalasia sub-type, those with UES abnormality had 26 times greater odds of poor treatment response than those with no UES abnormality(P = 0.009). Similarly, after controlling for treatment type, those with UES abnormality had 13.9 times greater odds of poor treatment response compared to those with no UES abnormality(P = 0.017).CONCLUSION: The presence of UES abnormalities in patients with achalasia significantly predicted poorer treatment response as compared to those with normal UES function. | Simon C Mathews Maria Ciarleglio Yamile Haito Chavez John O Clarke Ellen Stein Bani Chander Roland | 2014 | World Journal of Clinical Cases2014，2，9： | 5 |

| 10 | A next-generation marker genotyping platform(AmpSeq)in heterozygous crops:a case study for marker-assisted selection in grapevine显示文摘Marker-assisted selection(MAS)is often employed in crop breeding programs to accelerate and enhance cultivar development,via selection during the juvenile phase and parental selection prior to crossing.Next-generation sequencing and its derivative technologies have been used for genome-wide molecular marker discovery.To bridge the gap between marker development and MAS implementation,this study developed a novel practical strategy with a semi-automated pipeline that incorporates trait-associated single nucleotide polymorphism marker discovery,low-cost genotyping through amplicon sequencing(AmpSeq)and decision making.The results document the development of a MAS package derived from genotyping-by-sequencing using three traits(flower sex,disease resistance and acylated anthocyanins)in grapevine breeding.The vast majority of sequence reads(⩾99%)were from the targeted regions.Across 380 individuals and up to 31 amplicons sequenced in each lane of MiSeq data,most amplicons(83 to 87%)had<10%missing data,and read depth had a median of 220–244×.Several strengths of the AmpSeq platform that make this approach of broad interest in diverse crop species include accuracy,flexibility,speed,high-throughput,low-cost and easily automated analysis. | Shanshan Yang Jonathan Fresnedo-Ramíre Minghui Wang Linda Cote Peter Schweitzer Paola Barba Elizabeth M Takacs Matthew Clark James Luby David C Manns Gavin Sacks Anna Katharine Mansfield Jason Londo Anne Fennell David Gadoury Bruce Reisch Lance Cadle-Davidson Qi Sun | 2016 | Horticulture Research2016，3，1： | 2 |
