| 1 | Dysregulation of innate immunity in ulcerative colitis patients who fail anti-tumor necrosis factor therapy显示文摘AIM To study the innate immune function in ulcerative colitis(UC) patients who fail to respond to anti-tumor necrosis factor(TNF) therapy.METHODS Effects of anti-TNF therapy, inflammation and medications on innate immune function were assessed by measuring peripheral blood mononuclear cell(PBMC) cytokine expression from 18 inflammatory bowel disease patients pre- and 3 mo post-anti-TNF therapy. Toll-like receptor(TLR) expression and cytokine production post TLR stimulation was assessed in UC 'responders'(n = 12) and 'non-responders'(n = 12) and compared to healthy controls(n = 12). Erythrocyte sedimentation rate(ESR) and C-reactive protein(CRP) levels were measured in blood to assess disease severity/activity and inflammation. Pro-inflammatory(TNF, IL-1β, IL-6), immuno-regulatory(IL-10), Th1(IL-12, IFNγ) and Th2(IL-9, IL-13, IL-17A) cytokine expression was measured with enzyme-linked immunosorbent assay while TLR cellular composition and intracellular signalling was assessed with FACS.RESULTS Prior to anti-TNF therapy, responders and nonresponders had similar level of disease severity and activity. PBMC's ability to respond to TLR stimulation was not affected by TNF therapy, patient's severity of the disease and inflammation or their medication use. At baseline, non-responders had elevated innate but not adaptive immune responses compared to responders(P < 0.05). Following TLR stimulation, nonresponders had consistently reduced innate cytokine responses to all TLRs compared to healthy controls(P < 0.01) and diminished TNF(P < 0.001) and IL-1β(P < 0.01) production compared to responders. This innate immune dysfunction was associated with reduced number of circulating plasmacytoid dendritic cells(p DCs)(P < 0.01) but increased number of CD4+ regulatory T cells(Tregs)(P = 0.03) as well as intracellular accumulation of IRAK4 in non-responders following TLR-2,-4 and-7 activation(P < 0.001). CONCLUSION Reduced innate immunity in non-responders may explain reduced efficacy to anti-TNF therapy. These serological markers may prove useful in predicting the outcome of costly anti-TNF therapy. | Angela C Baird Dominic Mallon Graham Radford-Smith Julien Boyer Thierry Piche Susan L Prescott Ian C Lawrance Meri K Tulic | 2016 | World Journal of Gastroenterology2016，22，41： | 10 |
| 2 | Small bowel MRI enteroclysis or follow through:Which is optimal?显示文摘AIM:To determine if a nasojejunal tube(NJT) is required for optimal examination of enteroclysis and if patients can be examined only in the supine position.METHODS:Data were collected from all patients undergoing small bowel(SB) magnetic resonance imaging(MRI) examination over a 32-mo period.Patients either underwent a magnetic resonance(MR) follow-through(MRFT) or a MR enteroclysis(MRE) in the supine position.The quality of proximal and distal SB distension as well as the presence of motion artefact and image quality were assessed by 2 radiologists.RESULTS:One hundred and fourteen MR studies were undertaken(MRFT-49,MRE-65) in 108 patients in the supine position only.Image artefact was more frequent in MRE than in MRFT(29.2% vs 18.4%) ,but was not statistically significant(P = 0.30) .Adequate distension of the distal SB was obtained in 97.8% of MRFT examinations and in 95.4% of MRE examinations,respectively.Proximal SB distension was,however,less frequently optimal in MRFT than in MRE(P = 0.0036) ,particularly in patients over the age of 50 years(P = 0.0099) .Image quality was good in all examinations.CONCLUSION:All patients could be successfully imaged in the supine position.MRE and MRFT are equivalent for distal SB distension and artefact effects.Proximal SB distension is frequently less optimal in MRFT than in MRE.MRE is,therefore,the preferred MR examination method of the SB. | Ian C Lawrance Christopher J Welman Peter Shipman Kevin Murray | 2009 | World Journal of Gastroenterology2009，15，42： | 7 |
| 3 | Aberrant cytological localization of p16 and CDK4 in colorectal epithelia in the normal adenoma carcinoma sequence显示文摘AIM: To study the correlation between the patterns of subcellular expression of p16 and CDK4 in colorectal epithelia in the normal-adenoma-carcinoma sequence. METHODS: Paraffin sections of 43 cases of normal colorectal epithelia and corresponding adenomas as well as carcinomas were analysed immunocytochemically for subcellular expression of p16 and CDK4 proteins. RESULTS: Most carcinomas showed more cytoplasmic overexpression for p16 and CDK4 than the adenomas from which they arised or the adjacent normal mucosa. Most normal or non-neoplastic epithelia showed more p16 and CDK4 expression in the nucleus than their adjacent adenomas and carcinomas. There was a significant difference between the subcellular expression pattern of p16 and CDK4 in normal-adenoma-carcinoma sequence epithelia (P < 0.001). Neither p16 nor CDK4 subcellular patterns correlated with histological grade or Dukes’ stage. CONCLUSION: Interaction of expression of p16 and CDK4 plays an important role in the Rb/p16 pathway. Overexpression of p16 and CDK4 in the cytoplasm, as well as loss expression of p16 in the nucleus might be important in the evolution of colorectal carcinoma from adenoma and, of adenoma from normal epithelia. | PO Zhao Xin Mao Ian C Talbot | 2006 | World Journal of Gastroenterology2006，12，39： | 5 |

| 6 | Long-distance ABA transport can mediate distal tissue responses by affecting local ABA concentrations显示文摘Environmental stresses that perturb plant Hwater relations influence abscisic acid(ABA) concentrations, but it is unclear whether long-distance ABA transport contributes to changes in local ABA levels. To determine the physiological relevance of ABA transport, we made reciprocal-and self-grafts of ABA-deficient flacca mutant and wild-type(WT) tomato plants, in which low phosphorus(P) conditions decreased ABA concentrations while salinity increased ABA concentrations. Whereas foliar ABA concentrations in the WT scions were rootstock independent under control conditions, salinity resulted in long-distance transport of ABA: flacca scions had approximately twice as much ABA when grafted on WT rootstocks compared to flacca rootstocks. Root ABA concentrations were scion dependent: both WT and flacca rootstocks had less ABA with the flacca mutant scion than with the WT scion under control conditions. In WT scions, whereas rootstock genotype had limited effects on stomatal conductance under control conditions, a flacca rootstock decreased leaf area of stressed plants, presumably due to attenuated root-to-shoot ABA transport. In flacca scions, a WT rootstock decreased stomatal conductance but increased leaf area of stressed plants, likely due to enhanced root-to-shoot ABA transport. Thus, long-distance ABA transport can affect responses in distal tissues by changing local ABA concentrations. | Wenrao Li Carlos de Ollas Ian C Dodd | 2018 | Journal of Integrative Plant Biology2018，60，1： | 5 |
| 7 | Refining pathological evaluation of neoadjuvant therapy for adenocarcinoma of the esophagus显示文摘AIM:To assess tumour regression grade(TRG)and lymph node downstaging to help define patients who benefit from neoadjuvant chemotherapy.METHODS:Two hundred and eighteen consecutive patients with adenocarcinoma of the esophagus or gastro-esophageal junction treated with surgery alone or neoadjuvant chemotherapy and surgery between 2005and 2011 at a single institution were reviewed.Triplet neoadjuvant chemotherapy consisting of platinum,fluoropyrimidine and anthracycline was considered for operable patients(World Health Organization performance status≤2)with clinical stage T2-4 N0-1.Response to neoadjuvant chemotherapy(NAC)was assessed using TRG,as described by Mandard et al.In addition lymph node downstaging was also assessed.Lymph node downstaging was defined by cN1 at diagnosis:assessed radiologically(computed tomography,positron emission tomography,endoscopic ultrasonography),then pathologically recorded as N0 after surgery;ypN0 if NAC given prior to surgery,or pN0if surgery alone.Patients were followed up for 5 years post surgery.Recurrence was defined radiologically,with or without pathological confirmation.An association was examined between t TRG and lymph node downstaging with disease free survival(DFS)and a comprehensive range of clinicopathological characteristics.RESULTS:Two hundred and eighteen patients underwent esophageal resection during the study interval with a mean follow up of 3 years(median follow up:2.552,95%CI:2.022-3.081).There was a 1.8%(n=4)inpatient mortality rate.One hundred and thirty-six(62.4%)patients received NAC,with 74.3%(n=101)of patients demonstrating some signs of pathological tumour regression(TRG 1-4)and 5.9%(n=8)having a complete pathological response.Forty four point one percent(n=60)had downstaging of their nodal disease(cN1 to ypN0),compared to only 15.9%(n=13)that underwent surgery alone(pre-operatively overstaged:cN1 to pN0),(P<0.0001).Response to NAC was associated with significantly increased DFS(mean DFS;TRG 1-2:5.1years,95%CI:4.6-5.6 vs TRG 3-5:2.8 years,95%CI:2.2-3.3,P<0.0001).Nodal down-staging conferred a significant DFS advantage for those patients with a poor primary tumour response to NAC(median DFS;TRG 3-5 and nodal down-staging:5.533 years,95%CI:3.558-7.531 vs TRG 3-5 and no nodal down-staging:1.114 years,95%CI:0.961-1.267,P<0.0001).CONCLUSION:Response to NAC in the primary tumour and in the lymph nodes are both independently associated with improved DFS. | Fergus Noble Luke Nolan Adrian C Bateman James P Byrne Jamie J Kelly Ian S Bailey Donna M Sharland Charlotte N Rees Timothy J Iveson Tim J Underwood Andrew R Bateman | 2013 | World Journal of Gastroenterology2013，19，48： | 4 |
| 8 | Single-center study comparing computed tomography colonography with conventional colonoscopy显示文摘AIM:To compare the results from computed tomography (CT) colonography with conventional colonoscopy in symptomatic patients referred for colonoscopy. METHODS: The study included 227 adult outpatients, mean age 60 years, with appropriate indications for colonoscopy. CT colonography and colonoscopy were performed on the same day in a metropolitan teaching hospital. Colonoscopists were initially blinded to the results of CT colonography but there was segmental unblinding during the procedure. The primary outcome measures were the sensitivity and specificity of CT colonography for the identification of polyps seen at colonoscopy (i.e. analysis by polyp). Secondary outcome measures included an analysis by patient, extracolonic findings at CT colonography, adverse events with both procedures and patient acceptance and preference. RESULTS: Twenty-five patients (11%) were excluded from the analysis because of incomplete colonoscopy or poor bowel preparation that affected either CT colonography, colonoscopy or both procedures. Polyps and masses (usually cancers) were detected at colonoscopy and CT colonography in 35% and 42% of patients, respectively. Of nine patients with a finaldiagnosis of cancer, eight (89%) were identified by CT colonography as masses (5) or polyps (3). For polyps analyzed according to polyp, the overall sensitivity of CT colonography was 50% (95% CI, 39%-61%) but this increased to 71% (95% CI, 52%-85%) for polyps ≥ 6 mm in size. Similarly, specificity for all polyps was 48% (95% CI, 39%-58%) increasing to 67% (95% CI, 56%-76%) for polyps ≥ 6 mm. Adverse events were uncommon but included one colonic perforation at colonoscopy. Patient acceptance was high for both procedures but preference favoured CT colonography. CONCLUSION: Although CT colonography was more sensitive in this study than in some previous studies, the procedure is not yet sensitive enough for widespread application in symptomatic patients. | Ian C Roberts-Thomson Graeme R Tucker Peter J Hewett Peter Cheung Ruben A Sebben EE Win Khoo Julie D Marker Wayne K Clapton | 2008 | World Journal of Gastroenterology2008，14，3： | 4 |
| 9 | Preventing infective complications in inflammatory bowel disease显示文摘Over the past decade there has been a dramatic change in the treatment of patients with Crohn’s disease and ulcerative colitis,which comprise the inflammatory bowel diseases(IBD).This is due to the increasing use of immunosuppressives and in particular the biological agents,which are being used earlier in the course of disease,and for longer durations,as these therapies result in better clinical outcomes for patients.This,however,has the potential to increase the risk of opportunistic and serious infections in these patients,most of which are preventable.Much like the risk for potential malignancy resulting from the use of these therapies long-term,a balance needs to be struck between medication use to control the disease with minimization of the risk of an opportunistic infection.This outcome is achieved by the physician’s tailored use of justified therapies,and the patients’education and actions to minimize infection risk.The purpose of this review is to explore the evidence and guidelines available to all physicians managing patients with IBD using immunomodulating agents and to aid in the prevention of opportunistic infections. | Justine Mill Ian C Lawrance | 2014 | World Journal of Gastroenterology2014，20，29： | 4 |

| 12 | Iron:An emerging factor in colorectal carcinogenesis显示文摘The carcinogenic potential of iron in colorectal cancer(CRC) is not fully understood.Iron is able to undergo reduction and oxidation,making it important in many physiological processes.This inherent redox property of iron,however,also renders it toxic when it is present in excess.Iron-mediated generation of reactive oxygen species via the Fenton reaction,if uncontrolled,may lead to cell damage as a result of lipid peroxidation and oxidative DNA and protein damage.This may promote carcinogenesis through increased genomic instability,chromosomal rearrangements as well as mutations of proto-oncogenes and tumour suppressor genes. Carcinogenesis is also affected by inflammation which is exacerbated by iron.Population studies indicate an association between high dietary iron intake and CRC risk.In this editorial,we examine the link betweeniron-induced oxidative stress and inflammation on the pathogenesis of CRC. | Anita CG Chua Borut Klopcic Ian C Lawrance John K Olynyk Debbie Trinder | 2010 | World Journal of Gastroenterology2010，16，6： | 3 |
| 13 | Outcomes after arthroscopic repair of rotator cuff tears in the setting of mild to moderate glenohumeral osteoarthritis显示文摘BACKGROUND Rotator cuff pathology is a very common source of shoulder pain.Similarly,osteoarthritis of the glenohumeral joint can cause shoulder pain and produce similar symptoms.Surgical management can be indicated for both pathologies,however,outcomes data is limited when examining rotator cuff repair(RCR) in the setting of glenohumeral arthritis(GHOA).Thus,this study sought to determine outcomes for patients who undergo RCR in the setting of GHOA.AIM To evaluate if a relationship exists between outcomes of RCR in the setting of GHOA.METHODS This was a retrospective analysis of patients who underwent arthroscopic rotator cuff repair with concurrent glenohumeral osteoarthritis between 2010-2017.Patients were stratified based on rotator cuff tear size and glenohumeral osteoarthritis severity.Cohorts were paired 1:1 with patients without glenohumeral osteoarthritis.Patients included had a minimum two year follow-up.Rate of conversion to total shoulder arthroplasty,complication rates following initial surgery,and patient-reported outcome measures were collected.RESULTS A total of 142 patients were included.The number of patients that required total shoulder arthroplasty within two years after index surgery was low.2/71(2.8%) patients with GHOA,and 1/71(1.4%) without GHOA.Following rotator cuff repair,both groups showed favorable patientreported outcomes.CONCLUSION Patients with glenohumeral osteoarthritis who underwent arthroscopic rotator cuff repair showed comparable outcomes to patients without glenohumeral osteoarthritis. | Ian S Hong Allison J Rao Tyler L CarlLee Joshua D Meade Daniel J Hurwit Gregory Scarola David P Trofa Shadley C Schiffern Nady Hamid Patrick M Connor James E Fleischli Bryan Michael Saltzman | 2022 | World Journal of Orthopedics2022，13，7： | 2 |
| 14 | 肩关节肿瘤切除和重建后的患肢功能观察显示文摘目的肩关节肿瘤切除后,探讨不同重建方式的患肢长期功能。方法回顾性分析32例肩关节肿瘤保肢患者的临床资料。重建方式包括:8例一期肩关节融合,7例假体异体骨复合物,6例功能性间隔物,5例未行重建或悬吊术,3例假体,2例带血管蒂腓骨和1例异体骨。结果23例生存患者平均随访81个月。不同重建方式的功能评分分别为:一期肩关节融合为87%,主动运动优良,肩部有力;假体异体骨复合物为79%,间隔物为66%,未重建为85%,假体为60%和带血管蒂腓骨为73%。结论肩关节肿瘤的重建方式是根据切除范围和患者的实际需要来选择。如外展肌群无法重建,肩关节融合的功能良好,肩部有力;如果外展肌群可以重建,假体异体骨复合物功能较好。 | 王晋 Ian C Dickinson | 2006 | 中华外科杂志2006，44，12： | 2 |
| 15 | 在 7T 的多原子的磁性的回声光谱学的应用显示文摘 AIM: To discuss the advantages of ultra-high field (7T) for 1H and 13C magnetic resonance spectroscopy (MRS) studies of metabolism.made at both 3 and 7T using 1H MRS. Measurements of glycogen and lipids in muscle were measured using 13C and 1H MRS respectively. RESULTS: In the brain, increased signal-to-noise ratio (SNR) and dispersion allows spectral separation of the amino-acids glutamate, glutamine and γ-aminobutyric acid (GABA), without the need for sophisticated editing sequences. Improved quantification of these me-tabolites is demonstrated at 7T relative to 3T. SNR was 36% higher, and measurement repeatability (% coefficients of variation) was 4%, 10% and 10% at 7T, vs 8%, 29% and 21% at 3T for glutamate, glutamine and GABA respectively. Measurements at 7T were used to compare metabolite levels in the anterior cingulate cortex (ACC) and insula. Creatine and glutamate levels were found to be significantly higher in the insula compared to the ACC (P < 0.05). In muscle, the increased SNR and spectral resolution at 7T enables interleaved studies of glycogen (13C) and intra-myocellular lipid (IMCL) and extra-myocellular lipid (EMCL) (1H) following exercise and refeeding. Glycogen levels were sig-nificantly decreased following exercise (-28% at 50% VO2 max; -58% at 75% VO2 max). Interestingly, levels of glycogen in the hamstrings followed those in the quadriceps, despite reduce exercise loading. No changes in IMCL and EMCL were found in the study. CONCLUSION: The demonstrated improvements in brain and muscle MRS measurements at 7T will increase the potential for use in investigating human metabolism and changes due to pathologies. | Mary C Stephenson Frances Gunner Antonio Napolitano Paul L Greenhaff Ian A MacDonald Nadeem Saeed William Vennart Susan T Francis Peter G Morris | 2011 | World Journal of Radiology2011，3，4： | 2 |
