| 1 | Hypertriglyceridemia-induced pancreatitis: A case-based review显示文摘Hypertriglyceridemia is an established cause of pancreatitis. In a case-based approach, we present a review of hypertriglyceridemia and how it can cause pancreatitis. We outline how to investigate and manage such patients. A 35 year old man presented to the emergency department with abdominal pain and biochemical evidence of acute pancreatitis. There was no history of alcohol consumption and biliary imaging was normal. The only relevant past medical history was that of mild hyperlipidemia, treated with diet alone. Physical exam revealed epigastric tenderness, right lateral rectus palsy, lipemia retinalis, bitemporal hemianopsia and a delay in the relaxation phase of his ankle reflexes. Subsequent laboratory investigation revealed marked hypertriglyceridemia and panhypopituarism. An enhanced CT scan of the head revealed a large suprasellar mass impinging on the optic chiasm and hypothalamus. The patient was treated supportively; thyroid replacement and lipid lowering agents were started. He underwent a successful resection of a craniopharyngioma. Post- operatively, the patient did well on hormone replacement therapy. He has had no further attacks of pancreatitis. This case highlights many of the factors involved in the regulation of triglyceride metabolism. We review the common causes of hypertriglyceridemia and the proposed mechanisms resulting in pancreatitis. The incidence and management of hypertriglyceridemia- induced pancreatitis are also discussed. | S Ian Gan Alun L Edwards Christopher J Symonds Paul L Beck | 2006 | World Journal of Gastroenterology2006，12，44： | 35 |

| 3 | Correlation of MRI-determined small bowel Crohn’s disease categories with medical response and surgical pathology显示文摘AIM: To determine whether magnetic resonance imaging (MRI) can be used to categorize small bowel Crohn's disease (SB CD) into groups that correlate with response to medical therapy and surgical pathology.METHODS: Data was collected from all patients with MRI evidence of SB CD without significant colonic disease over a 32-mo period. Two radiologists, blinded to clinical findings, evaluated each MRI and grouped them based on bowel wall thickness and wall enhancement. These categories were: (1) 'fibrosis', (2) 'mild segmental hyper-enhancement and mild wall thickening', (3) 'mild segmental hyper-enhancement and marked wall thickening', (4) 'marked segmental transmural hyper-enhancement'. Patient response to additional medical therapy post-MRI was prospectively determined at 8-wk. Non-responders underwent endoscopy and were offered therapeutic endoscopy or surgery. Surgical pathology was assessed against the MRI category. RESULTS: Fifty-five patients were included. Females and category '2' patients were more likely, and patients with luminal narrowing and hold-up less likely, to respond to medical therapy (P < 0.05). Seventeen patients underwent surgery. The surgical pathologicalfindings of fibrosis and the severity of inflammation correlated with the MRI category in all cases.CONCLUSION: Our fi ndings suggest that SB CD can be grouped by the MRI f indings and that these groups are associated with patients more likely to respond to continued medical therapy. The MRI categories also correlated with the presence and level of intestinal inflammation and fibrosis on surgical pathology, and may be of prognostic use in the management of CD patients. | Ian Craig Lawrance Christopher J Welman Peter Shipman Kevin Murray | 2009 | World Journal of Gastroenterology2009，15，27： | 12 |
| 4 | One hundred and seventy-eight consecutive pancreatoduodenectomies without mortality:role of the multidisciplinary approach显示文摘BACKGROUND:Pancreatoduodenectomy offers the only chance of cure for patients with periampullary cancers.This,however,is a major undertaking in most patients and is associated with a significant morbidity and mortality.A multidisciplinary approach to the workup and follow-up of patients undergoing pancreatoduodenectomy was initiated at our institution to improve the diagnosis,resection rate,mortality and morbidity.We undertook the study to assess the effect of this approach on diagnosis,resection rates and short-term outcomes such as morbidity and mortality.METHODS:A prospective database of patients presenting with periampullary cancers to a single surgeon between April 2004 and April 2010 was reviewed.All cases were discussed at a multidisciplinary meeting comprising surgeons,gastroenterologists,radiologists,oncologists,radiation oncologists,pathologists and nursing staff.A standardized investigation and management algorithm was followed.Complications were graded according to the Clavien-Dindo classification.RESULTS:A total of 295 patients with a periampullary lesion were discussed and 178 underwent pancreatoduodenectomy (resection rate 60%).Sixty-one patients (34%) required either a vascular or an additional organ resection.Eighty-nine patients experienced complications,of which the commonest was blood transfusion (12%).Thirty-four patients (19%) had major complications,i.e.grade 3 or above.There was no in-hospital,30-day or 60-day mortality.CONCLUSIONS:Pancreatoduodenectomy can safely be performed in high-volume centers with very low mortality.The surgeon's role should be careful patient selection,intensive preoperative investigations,use of a team approach,and an unbiased discussion at a multidisciplinary meeting to optimize the outcome in these patients. | Jaswinder S Samra Raul Alvarado Bachmann Julian Choi Anthony Gill Michael Neale Vikram Puttaswamy Cameron Bell Ian Norton Sarah Cho Steven Blome Ritchie Maher Sivakumar Gananadha Thomas J Hugh | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，4： | 8 |
| 5 | Apoptosis block as a barrier to effective therapy in non small cell lung cancer显示文摘Lung cancer, is the most common cause of cancer death in men and second only to breast cancer in women. Currently, the first line therapy of choice is platinumbased combination chemotherapy. A therapeutic plateau has been reached with the prognosis for patients with advanced non-small cell lung cancer(NSCLC) remaining poor. New biomarkers of prognosis as well as new therapies focusing on molecular targets are emerging helping to identify patients who are likely to benefit from therapy. Despite this, drug resistance remains the major cause for treatment failure. In this article we review the role of apoptosis in mediating drug resistance in NSCLC. Better understanding of this fundamental biological process may provide a rationale for overcoming the current therapeutic plateau. | Ian Paul J Mark Jones | 2014 | World Journal of Clinical Oncology2014，5，4： | 7 |
| 6 | Radiofrequency ablation for early oesophageal squamous neoplasia:Outcomes form United Kingdom registry显示文摘AIM:To report outcomes on patients undergoing radiofrequency ablation(RFA)for early oesophageal squamous neoplasia from a National Registry.METHODS:A Prospective cohort study from 8 tertiary referral centres in the United Kingdom.Patients with squamous high grade dysplasia(HGD)and early squamous cell carcinoma(ESCC)confined to the mucosa were treated.Visible lesions were removed by endoscopic mucosal resection(EMR)before RFA.Following initial RFA treatment,patients were followed up 3monthly.Residual flat dysplasia was treated with RFA until complete reversal dysplasia(CR-D)was achieved or progression to invasive Squamous cell cancer defined as infiltration into the submucosa layer or beyond.The main outcome measures were CR-D at 12 mo from start of treatment,long term durability,progression to cancer and adverse events.RESULTS:Twenty patients with squamous HGD/ESCC completed treatment protocol.Five patients(25%)had EMR before starting RFA treatment.CR-D was 50%at12 mo with a median of 1 RFA treatment,mean 1.5(range 1-3).Two further patients achieved CR-D with repeat RFA after this time.Eighty per cent with CR-D remain dysplasia free at latest biopsy,with median follow up 24 mo(IQR 17-54).Six of 20 patients(30%)progressed to invasive cancer at 1 year.Four patients(20%)required endoscopic dilatations for symptomatic structuring after treatment.Two of these patients have required serial dilatations thereafter for symptomatic dysphagia with a median of 4 dilatations per patient.The other 2 patients required only a single dilatation to achieve an adequate symptomatic response.One patient developed cancer during follow up after end of treatment protocol.CONCLUSION:The role of RFA in these patients re-mains unclear.In our series 50%patients responded at12 mo.These figures are lower than limited published data. | Rehan J Haidry Mohammed A Butt Jason Dunn Matthew Banks Abhinav Gupta Howard Smart Pradeep Bhandari Lesley Ann Smith Robert Willert Grant Fullarton Morris John Massimo Di Pietro Ian Penman Marco Novelli Laurence B Lovat | 2013 | World Journal of Gastroenterology2013，19，36： | 7 |
| 7 | 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 |
| 8 | Characterisation of Neonicotinoid and Pymetrozine Resistance in Strains of Bemisia tabaci(Hemiptera:Aleyrodidae)from China显示文摘Four strains of the Q biotype and one of the B biotype of the whitefly Bemisia tabaci collected from China were characterised for resistance to four neonicotinoid insecticides and pymetrozine.Q biotype strains showed moderate to strong resistance to imidacloprid,thiamethoxam and acetamiprid,but little or no cross-resistance to dinotefuron.Resistance to neonicotinoids was consistently associated with resistance to pymetrozine,despite the latter having a distinct(though unresolved)mode of action.The single B biotype strain proved largely susceptible to all the insecticides investigated.Resistance in the Q biotype strains was associated with over-expression of a cytochrome P450 monooxygenase gene,CYP6CM1,whose substrate specificity presumably accounts for the observed cross-resistance profiles. | RAO Qiong XU Yong-hua LUO Chen ZHANG Hong-yu Christopher M Jones Greg J Devine KevinGorman Ian Denholm | 2012 | Journal of Integrative Agriculture2012，11，2： | 7 |
| 9 | Biomarkers in schizophrenia:A focus on blood based diagnostics and theranostics显示文摘Identifying biomarkers that can be used as diagnostics or predictors of treatment response(theranostics) in people with schizophrenia(Sz) will be an important step towards being able to provide personalized treatment. Findings from the studies in brain tissue have not yet been translated into biomarkers that are practical in clinical use because brain biopsies are not acceptable and neuroimaging techniques are expensive and the results are inconclusive. Thus, in recent years, there has been search for blood-based biomarkers for Sz as a valid alternative. Although there are some encouraging preliminary data to support the notion of peripheral biomarkers for Sz, it must be acknowledged that Sz is a complex and heterogeneous disorder which needs to be further dissected into subtype using biological based and clinical markers. The scope of this review is to critically examine published blood-based biomarker of Sz, focusing on possible uses for diagnosis, treatment response, or their relationship with schizophreniaassociated phenotype. We sorted the studies into six categories which include:(1) brain-derived neurotrophic factor;(2) inflammation and immune function;(3) neurochemistry;(4) oxidative stress response and metabolism;(5) epigenetics and micro RNA; and(6) transcriptome and proteome studies. This review also summarized the molecules which have been conclusively reported as potential blood-based biomarkers for Sz in different blood cell types. Finally, we further discusses the pitfall of current blood-based studies and suggest that a prediction model-based, Sz specific, bloodoriented study design as well as standardize blood collection conditions would be useful for Sz biomarker development. | Chi-Yu Lai Elizabeth Scarr Madhara Udawela Ian Everall Wei J Chen Brian Dean | 2016 | World Journal of Psychiatry2016，6，1： | 6 |

| 12 | Capsule endoscopy in suspected small bowel Crohn's disease:Economic impact of disease diagnosis and treatment显示文摘AIM: To model clinical and economic benef its of capsule endoscopy (CE) compared to ileo-colonoscopy and small bowel follow-through (SBFT) for evaluation of suspected Crohn’s disease (CD). METHODS: Using decision analytic modeling, total and yearly costs of diagnostic work-up for suspected CD were calculated, including procedure-related adverse events, hospitalizations, off ice visits, and medications. The model compared CE to SBFT following ileo-colonoscopy and secondarily compared CE to SBFT for initial evaluation. RESULTS: Aggregate charges for newly diagnosed, medically managed patients are approximately $8295. Patients requiring aggressive medical management costs are $29 508; requiring hospitalization, $49 074. At sensitivity > 98.7% and specifi city of > 86.4%, CE is less costly than SBFT. CONCLUSION: Costs of CE for diagnostic evaluationof suspected CD is comparable to SBFT and may be used immediately following ileo-colonoscopy. | Jonathan A Leighton Ian M Gralnek Randel E Richner Michael J Lacey Frank J Papatheofanis | 2009 | World Journal of Gastroenterology2009，15，45： | 5 |

| 14 | 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 |
| 15 | 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 |
| 16 | Radial artery access site complications during cardiac procedures,clinical implications and potential solutions: The role of nitric oxide显示文摘Percutaneous coronary intervention for the treatment of coronary artery disease is most commonly performed in the UK through the radial artery,as this is considered to be safer than the femoral approach.However,despite improvements in technology and techniques,complications can occur.The most common complication,arterial spasm,can cause intense pain and,in some cases,procedural failure.The incidence of spasm is dependent on several variables,including operator experience,artery size,and equipment used.An antispasmolytic cocktail can be applied to reduce spasm,which usually includes an exogenous nitric oxide(NO)donor(glyceryl trinitrate).NO is an endogenous local vasodilator and therefore is a potential target for anti-spasm intervention.However,systemic administration can result in unwanted side-effects,such as hypotension.A method that adopts local delivery of NO might be advantageous.This review article describes the mechanisms involved in radial artery spasm,discusses the advantages and disadvantages of current strategies to reduce spasm,and highlight the potential of NO-loaded nanoporous materials for use in this setting. | Emma M Coghill Timothy Johnson Russell E Morris Ian L Megson Stephen J Leslie | 2020 | World Journal of Cardiology2020，12，1： | 4 |
| 17 | Opioid growth factor and the treatment of human pancreatic cancer:A review显示文摘Opioid growth factor(OGF),chemically termed[Met5]-enkephalin,and its receptor,OGF receptor(OGFr),form a biological axis that tonically regulates cell proliferation by delaying the G1/S interface of the cell cycle under homeostatic conditions or in neoplasia.Modulation of the OGF-OGFr pathway mediates the course of pancreatic cancer,with exogenous OGF or upregulation of OGFr repressing growth of human pancreatic cancer cells in culture and in nude mice.OGF therapy alone or in combination with standard chemotherapies such as gemcitabine and 5-fluorouracil results in enhanced inhibition of DNA synthesis and tumor growth.Molecular manipulation of OGFr confirms that the receptor is specific for OGF’s inhibitory action.Preclinical studies have warranted PhaseⅠand PhaseⅡclinical trials using OGF infusions as a treatment for patients with advanced,unresectable pancreatic cancers.OGF,an endogenous neuropeptide,is a safe,non-toxic,and effective biotherapy that utilizes the OGF-OGFr axis to mediate pancreatic tumor progression. | Ian S Zagon Patricia J McLaughlin | 2014 | World Journal of Gastroenterology2014，20，9： | 4 |
| 18 | Comparison of visual acuity outcomes between ranibizumab and bevacizumab treatment in neovascular age-related macular degeneration显示文摘AIM:To compare visual acuity(VA) outcomes between intravitreal injection of bevacizumab and ranibizumab in the treatment of neovascular age-related macular degeneration(AMD).· METHODS:We conducted a consecutive,retrospective case series study in patients with newly diagnosed all type choroidal neovascularization(CNV) secondary to AMD who received an intravitreal injection of bevacizumab(1.25mg) or ranibizumab(0.3mg) at Lions Eye Institute,Western Australia from Mar.2006 to May 2008.All patients received injection at baseline with additional monthly injections given at the discretion of the treating physician.Main outcome measures were changes in VA.· RESULTS:There were 371 consecutive patients received injection at least in one eye with at least 6 months of follow up(median of 12.0 months).Bevacizumab treatment prevented 221 out of 278(79.5%) patients from losing <15 letters in VA compared with 79 out of 93(84.9%) of ranibizumab treated patients(P=0.25).While 68(24.5%) of bevacizumab treated patients gained ≥15 letters of VA compared with 24(25.8%) of ranibizumab treated patients(P=0.79).75.3% and 66.2% patients benefited from ranibizumab and bevacizumab respectively with final VA better than 6/60(P=0.10).Multivariate analysis showed that pre-treatment VA was negatively associated with benefit outcome.Assignment of injection was not associated with VA outcome of benefit after adjusting the covariate(P=0.857).CONCLUSION:There are no difference in treatment efficacy in terms of VA between bevacizumab and ranibizumab in routine clinical condition. | Ian J Constable Ian L McAllister Timothy Isaacs | 2011 | International Journal of Ophthalmology(English edition)2011，4，1： | 3 |

| 20 | Giant hepatic extra-gastrointestinal stromal tumor treated with cytoreductive surgery and adjuvant systemic therapy:A case report and review of literature显示文摘BACKGROUND Primary extra-gastrointestinal stromal tumors(E-GIST)of the liver are rare.The clinical presentation may range from asymptomatic to bleeding or manifestations of mass effect.Oncologic surgery followed by adjuvant therapy with imatinib is the standard of care.However,under specific circumstances,a cytoreductive approach may represent a therapeutic option.We describe herein the case of an 84-year-old woman who presented with a tender,protruding epigastric mass.Abdominal computed tomography scan revealed a large,heterogeneous mass located across segments III,IV,V,and VIII of the liver.The initial approach was transarterial embolization of the tumor,which elicited no appreciable response.Considering the large size and central location of the tumor and the advanced age of the patient,non-anatomic complete resection was indicated.Due to substantial intraoperative bleeding and hemodynamic instability,only a near-complete resection could be achieved.Histopathology and immunohistochemical staining confirmed the diagnosis of primary E-GIST of the liver.Considering the risk/benefit ratio for therapeutic options,debulking surgery may represent a strategy to control pain and prolong survival.CASE SUMMARY Here,we present a case report of a patient diagnosed with E-GIST primary of the liver,which was indicated a cytoreductive surgery and adjuvant therapy with imatinib.CONCLUSION E-GIST primary of the liver is a rare conditional,the treatment is with systemic therapy and total resection surgery.However,a cytoreductive surgery will be necessary when a complete resection is no possible. | Michel Ribeiro Fernandes Caroline Lorenzoni Almeida Ghezzi Tomaz J M Grezzana-Filho Flávia Heinz Feier Ian Leipnitz Aljamir Duarte Chedid Carlos Thadeu Schmidt Cerski Marcio Fernandes Chedid Cléber RositoPinto Kruel | 2021 | World Journal of Gastrointestinal Surgery2021，13，3： | 3 |
