| 1 | Management of borderline and locally advanced pancreatic cancer:Where do we stand?显示文摘Many patients with pancreas cancer present with locally advanced pancreatic cancer(LAPC).The principle tools used for diagnosis and staging of LAPC include endoscopic ultrasound,axial imaging with computed tomography and magnetic resonance imaging,and diagnostic laparoscopy.The definition of resectability has historically been vague,as there is considerable debate and controversy as to the definition of LAPC.For the patient with LAPC,there is some level of involvement of the surrounding vascular structures,which include the superior mesenteric artery,celiac axis,hepatic artery,superior mesenteric vein,or portal vein.When feasible,most surgeons would recommend possible surgical resection for patients with borderline LAPC,with the goal of an R0 resection.For initially unresectable LAPC,neoadjuvant should be strongly considered.Specifically,these patients should be offered neoadjuvant therapy,and the tumor should be assessed for possible response and eventual resection.The efficacy of neoadjuvant therapy with this approach as a bridge to potential curative resection is broad,ranging from 3%-79%.The different modalities of neoadjuvant therapy include sin-gle or multi-agent chemotherapy combined with radiation,chemotherapy alone,and chemotherapy followed by chemotherapy with radiation.This review focuses on patients with LAPC and addresses recent advances and controversies in the field. | Jin He Andrew J Page Matthew Weiss Christopher L Wolfgang Joseph M Herman Timothy M Pawlik | 2014 | World Journal of Gastroenterology2014,20,9: | 11 |
| 2 | Update on the natural history of intracranial atherosclerotic disease: A critical review显示文摘Intracranial atherosclerotic disease (ICAD) contributes to a significant number of ischemic strokes. There is debate in the recent literature concerning the impact of the location of stenosis in ICAD on outcome. Some reports have suggested that disease processes and outcomes vary by vessel location, potentially altering the natural history and indications for intervention. Here we have performed a comprehensive, critical review of the natural history of ICAD by vessel in an attempt to assess the differences in disease specific to each of the vascular territories. Our assessment concludes that only minor differences exist between patients with different vessels affected in vessel-specific ICAD. We have found that middle cerebral artery disease confers a lower mortality than vessel-specific ICAD in other intracranial vessels, asymptomatic disease follows a more benign course than symptomatic disease, andthat plaque progression or the detection of microemboli on transcranial Doppler may predict poor outcome. Given the expanding indications for treatment of ICAD and rapidly developing endovascular techniques to confront this disease, a thorough understanding of the natural history of ICAD aids the interventional neuroradiologist in determining when to treat and how to predict outcome in this patient population. | Ricardo J Komotar Christopher P Kellner Daniel M Raper Dorothea Strozyk Randall T Higashida Philip M Meyers | 2010 | World Journal of Radiology2010,2,5: | 8 |
| 3 | Dietary advanced glycation end-products aggravate non-alcoholic fatty liver disease显示文摘AIM To determine if manipulation of dietary advanced glycation end product(AGE), intake affects nonalcoholic fatty liver disease(NAFLD) progression and whether these effects are mediated via RAGE. METHODS Male C57Bl6 mice were fed a high fat, high fructose, high cholesterol(HFHC) diet for 33 wk and compared with animals on normal chow. A third group were given a HFHC diet that was high in AGEs. Another group was given a HFHC diet that was marinated in vinegar to prevent the formation of AGEs. In a second experiment, RAGE KO animals were fed a HFHC diet or a high AGE HFHC diet and compared with wildtype controls. Hepatic biochemistry, histology, picrosirius red morphometry and hepatic mR NA were determined. RESULTS Long-term consumption of the HFHC diet generated significant steatohepatitis and fibrosis after 33 wk. In this model, hepatic 4-hydroxynonenal content(a marker of chronic oxidative stress), hepatocyte ballooning, picrosirius red staining, α-smooth muscle actin and collagen type 1A gene expression were all significantly increased. Increasing the AGE content of the HFHC diet by baking further increased these markers of liver damage, but this was abrogated by pre-marination in acetic acid. In response to the HFHC diet, RAGE-/-animals developed NASH of similar severity to RAGE+/+ animals but were protected from the additional harmful effects of the high AGE containing diet. Studies in isolated Kupffer cells showed that AGEs increase cell proliferation and oxidative stress, providing a likely mechanism through which these compounds contribute to liver injury. CONCLUSION In the HFHC model of NAFLD, manipulation of dietary AGEs modulates liver injury, inflammation, and liver fibrosis via a RAGE dependent pathway. This suggests that pharmacological and dietary strategies targeting the AGE/RAGE pathway could slow the progression of NAFLD. | Christopher Leung Chandana B Herath Zhiyuan Jia Sof Andrikopoulos Bronwyn E Brown Michael J Davies Leni R Rivera John B Furness Josephine M Forbes Peter W Angus | 2016 | World Journal of Gastroenterology2016,22,35: | 7 |
| 4 | 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 |
| 5 | Risk stratification for ST segment elevation myocardial infarction in the era of primary percutaneous coronary intervention显示文摘Acute coronary syndromes presenting with ST elevation are usually treated with emergency reperfusion/revascularisation therapy. In contrast current evidence and national guidelines recommend risk stratification for non ST segment elevation myocardial infarction(NSTEMI) with the decision on revascularisation dependent on perceived clinical risk. Risk stratification for STEMI has no recommendation. Statistical risk scoring techniques in NSTEMI have been demonstrated to improve outcomes however their uptake has been poor perhaps due to questions over their discrimination and concern for application to individuals who may not have been adequately represented in clinical trials. STEMI is perceived to carry sufficient risk to warrant emergency coronary intervention [by primary percutaneous coronary intervention(PPCI)] even if this results in a delay to reperfusion with immediate thrombolysis. Immediate thrombolysis may be as effective in patients presenting early, or at low risk, but physicians are poor at assessing clinical and procedural risks and currently are not required to consider this. Inadequate data on risk stratification in STEMI inhibits the option of immediate fibrinolysis, which may be cost-effective. Currently the mode of reperfusion for STEMI defaults to emergency angiography and percutaneous coronary intervention ignoring alternative strategies. This review article examines the current risk scores and evidence base for risk stratification for STEMI patients. The requirements for an ideal STEMI risk score are discussed. | Richard A Brogan Christopher J Malkin Philip D Batin Alexander D Simms James M McLenachan Christopher P Gale | 2014 | World Journal of Cardiology2014,6,8: | 6 |
| 6 | 子痫前期:病理生理学和临床意义显示文摘子痫前期是一种常见疾病,尤其影响首次妊娠。其临床表现多样,但通常表现为高血压和蛋白尿。这些全身症状是由于在合体滋养细胞的压力作用下,胎盘释放了可溶性因子。子痫前期主要有早发型和迟发型2种亚型,其他几种亚型目前尚未确定。早发型子痫前期是由于胎盘缺陷而出现,而迟发型子痫前期可能是由于胎盘的正常衰老,以及母体对心血管和代谢疾病的遗传易感性交互产生。子痫前期因胎盘和母体因素产生的原因因人而异。最近的研究主要集中在早孕期的胎盘-子宫相互作用。本文旨在对关于子痫前期的预测、预防和治疗方法的最新文献进行归纳综述。 | Graham J Burton Christopher W Redman James M Roberts Ashley Moffett 秦萌(译) 金滢 潘凌亚(校 | 2019 | 英国医学杂志中文版2019,22,11: | 6 |

| 8 | Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed. | Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee | 2014 | World Journal of Clinical Oncology2014,5,2: | 5 |
| 9 | Tumor Antigen Specific Activation of Primary Human T-Cells Expressing a Virally Encoded Chimeric T-Cell Receptor Specific for p185HER2显示文摘We have developed and tested chimeric T-cell receptors (TCR) specific for p185HER2. In these experiments, retroviral vectors expressing the N29γ or N29ζ receptors were constructed in pRET6. Amphotropic viral producer cells were established in the GALV-based PG13 packaging cell line. Ficoll purified human peripheral blood lymphocytes (PBL) were virally transduced using an optimized protocol incorporating activation with immobilized anti-CD3/anti-CD28 monoclonal anti- bodies, followed by viral infection in the presence of fibronectin fragment CH296. Transduced cells were co-cultured with human tumor cell lines that overexpress (SK-OV-3) or underexpress (MCF7) p185HER2 to assay for antigen specific im- mune responses. Both CM+ and CD8+ T-cells transduced with the N29γ or N29ζ chTCR demonstrated HER2-specific anti- gen responses, as determined by release of Th1 like cytokines, and cellular cytotoxicity assays. Our results support the fea- sibility of adoptive immunotherapy with genetically modified T-cells expressing a chTCR specific for p185HER2. | 杨建民 Michael S FRIEDMAN Christopher M REYNOLDS Marianne T HUBEN Lee WILKE Jennifer FULLER 李桥 Zelig ESHHAR James J MULE Kevin T MCDONAGH | 2004 | Journal of Microbiology and Immunology2004,2,4: | 5 |

| 12 | Statin use and cognitive function in middle-aged adults with type 1 diabetes显示文摘AIM To test associations between statin use and cognitive impairment in adults with childhood-onset type 1 diabetes(T1D).METHODS In 2010-13, n = 108 middle-aged participants from ongoing observational Pittsburgh Epidemiology of Diabetes Complications Study underwent neurocognitive assessment(mean age and T1 D duration of 49 and 41 years, respectively). All were diagnosed with childhoodonset(i.e., prior to age 18) T1 D between 1950 and 1980 and were seen within one year of diagnosis at Children's Hospital of Pittsburgh. Self-reported statin use(yes/no and if yes, name of statin) was collected biennially from parent study baseline(1986-1988) to time of neurocognitive testing. Logistic regression models tested associations between statin use groups and cognitive impairment(defined as having two or more cognitive test scores 1.5SD or worse than published norms) while linear regression models tested associations between statin use groups and cognitive domain z-scores(domains: Verbal IQ, memory, executive function, psychomotor speed, and visuo-construction). All models controlled for education and age. To address confounding by indication, models were repeated using a propensity score for statin use.RESULTS Of the 108 participants, 51 reported never using statins. Median duration of statin use among the 57 ever users was 6 years. These 57 ever statin users were split to create two groups(≤ or > median years of statin use): 1-6 years(n = 25), and 7-12 years(n = 32). Compared with never users, using statins 1-6 years tripled the odds of cognitive impairment(OR = 3.16; 95%CI: 0.93-10.72; P = 0.06) and using statins 7-12 years almost quintupled the odds of cognitive impairment(OR = 4.84; 95%CI: 1.63-14.44; P = 0.005). Compared with never users, using statins 1-6 or 7-12 years was related to worse performance in the memory domain(β =-0.52; P = 0.003, and-0.39; P = 0.014, respectively). Adjusting for coronary artery disease, low density lipoprotein cholesterol, and Apo E4 status did not substantially alter results, and none of these covariates were significantly related to cognitive outcomes(all P > 0.05). Propensity score analyses support that associations between poor cognitive outcomes and statin use were not due merely to confounding by indication. CONCLUSION Statin use was associated with cognitive impairment, particularly affecting memory, in these middle-aged adults with childhood-onset T1 D, whom at this age, should not yet manifest age-related memory deficits. | Karen A Nunley Trevor J Orchard Christopher M Ryan Rachel Miller Tina Costacou Caterina Rosano | 2017 | World Journal of Diabetes2017,8,6: | 2 |

| 16 | Evolution of endovascular mechanical thrombectomy for acute ischemic stroke显示文摘Acute ischemic stroke(AIS) is a common medical problem associated with significant morbidity and mortality worldwide. A small proportion of AIS patients meet eligibility criteria for intravenous thrombolysis(IVT) with recombinant tissue plasminogen activator, and its efficacy for large vessel occlusion is poor. Therefore, an increasing number of patients with AIS are being treated with endovascular mechanical thrombectomy when IVT is ineffective or contraindicated. Rapid advancement in catheter-based and endovascular device technology has led to significant improvements in rates of cerebral reperfusion with these devices. Stentrievers and modern aspiration catheters have now surpassed earlier generation devices in the degree and rapidity of revascularization. This progress has been achieved with no concurrent increase in risk of major complications or mortality, both when used alone or in combination with IVT. The initial randomized controlled trials comparing endovascular therapy to IVT for AIS failed to show superior outcomes with endovascular treatment, butkey limitations of each trial may limit the significance of these results to current practice. While endovascular devices and operator experience continue to evolve, we are optimistic that this will be accompanied by improvements in patient outcomes. This review highlights the major endovascular devices used in current practice and the trials which have investigated their efficacy. | Colin J Przybylowski Dale Ding Robert M Starke Christopher R Durst R Webster Crowley Kenneth C Liu | 2014 | World Journal of Clinical Cases2014,2,11: | 2 |

| 18 | Transepithelial leak in Barrett's esophagus patients: The role of proton pump inhibitors显示文摘AIM: To determine if the observed paracellular sucrose leak in Barrett's esophagus patients is due to their proton pump inhibitor (PPI) use. METHODS: The in vivo sucrose permeability test was administered to healthy controls, to Barrett's patients and to non-Barrett's patients on continuous PPI therapy. Degree of leak was tested for correlation with presence of Barrett's, use of PPIs, and length of Barrett's segment and duration of PPI use. RESULTS: Barrett's patients manifested a near 3-fold greater, upper gastrointestinal sucrose leak than healthy controls. A decrease of sucrose leak was observed in Barrett's patients who ceased PPI use for 7 d.Although initial introduction of PPI use (in a PPI-na ve population) results in dramatic increase in sucrose leak, long-term, continuous PPI use manifested a slow spontaneous decline in leak. The sucrose leak observed in Barrett's patients showed no correlation to the amount of Barrett's tissue present in the esophagus. CONCLUSION: Although future research is needed to determine the degree of paracellular leak in actual Barrett's mucosa, the relatively high degree of leak observed with in vivo sucrose permeability measurement of Barrett's patients reflects their PPI use and not their Barrett's tissue per se . | Christopher Farrell Melissa Morgan Owen Tully Kevin Wolov Keith Kearney Benjamin Ngo Giancarlo Mercogliano James J Thornton Mary Carmen Valenzano James M Mullin | 2012 | World Journal of Gastroenterology2012,18,22: | 2 |
