| 1 | T1ρ/T2 mapping and histopathology of degenerative cartilage in advanced knee osteoarthritis显示文摘AIM To investigate whether normal thickness cartilage in osteoarthritic knees demonstrate depletion of proteoglycan or collagen content compared to healthy knees.METHODS Magnetic resonance(MR) images were acquired from5 subjects scheduled for total knee arthroplasty(TKA)(mean age 70 years) and 20 young healthy control subjects without knee pain(mean age 28.9 years). MR images of T1ρ mapping, T2 mapping, and fat suppressed proton-density weighted sequences were obtained.Following TKA each condyle was divided into 4 parts(distal medial, posterior medial, distal lateral, posterior lateral) for cartilage analysis. Twenty specimens(bone and cartilage blocks) were examined. For each joint,the degree and extent of cartilage destruction was determined using the Osteoarthritis Research Society International cartilage histopathology assessment system.In magnetic resonance imaging(MRI) analysis, 2 readers performed cartilage segmentation for T1ρ/T2 values and cartilage thickness measurement.RESULTS Eleven areas in MRI including normal or near normal cartilage thickness were selected. The corresponding histopathological sections demonstrated mild to moderate osteoarthritis(OA). There was no significant difference in cartilage thickness in MRI between control and advanced OA samples [medial distal condyle, P = 0.461;medial posterior condyle(MPC), P = 0.352; lateral distal condyle, P = 0.654; lateral posterior condyle, P = 0.550],suggesting arthritic specimens were morphologically similar to normal or early staged degenerative cartilage.Cartilage T2 and T1ρ values from the MPC were significantly higher among the patients with advanced OA(P= 0.043). For remaining condylar samples there was no statistical difference in T2 and T1ρ values between cases and controls but there was a trend towards higher values in advanced OA patients. CONCLUSION Though cartilage is morphologically normal or near normal, degenerative changes exist in advanced OA patients. These changes can be detected with T2 and T1ρ MRI techniques. | Benjamin S Kester Philip M Carpenter Hon J Yu Taiki Nozaki Yasuhito Kaneko Hiroshi Yoshioka Ran Schwarzkopf | 2017 | World Journal of Orthopedics2017，8，4： | 12 |

| 3 | 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 |

| 5 | Predictors of suboptimal bowel preparation in asymptomatic patients undergoing average-risk screening colonoscopy显示文摘AIM To identify risk factors for a suboptimal preparation among a population undergoing screening or surveillance colonoscopy.METHODS Retrospective review of the University of Michigan and Veteran's Administration(VA) Hospital records from 2009 to identify patients age 50 and older who underwent screening or surveillance procedure and had resection of polyps less than 1 cm in size and no more than 2 polyps. Patients with inflammatory bowel disease or a family history of colorectal cancer were excluded. Suboptimal procedures were defined as procedure preparations categorized as fair, poor or inadequate by the endoscopist. Multivariable logistic regression was used to identify predictors of suboptimal preparation.RESULTS Of 4427 colonoscopies reviewed, 2401 met our inclusion criteria and were analyzed. Of our population, 16% had a suboptimal preparation. African Americans were 70% more likely to have a suboptimal preparation(95%CI: 1.2-2.4). Univariable analysis revealed that narcotic and tricyclic antidepressants(TCA) use, diabetes, prep type, site(VA vs non-VA), and presence of a gastroenterology(GI) fellow were associated with suboptimal prep quality. In a multivariable model controlling for gender, age, ethnicity, procedure site and presence of a GI fellow, diabetes [odds ratio(OR) = 2.3; 95%CI: 1.6-3.2], TCA use(OR = 2.5; 95%CI: 1.3-4.9), narcotic use(OR = 1.7; 95%CI: 1.2-2.5) and Miralax-Gatorade prep vs 4L polyethylene glycol 3350(OR = 0.6; 95%CI: 0.4-0.9) were associated with a suboptimal prep quality. CONCLUSION Diabetes, narcotics use and TCA use were identified as predictors of poor preparation in screening colonoscopies while Miralax-Gatorade preps were associated with better bowel preparation. | Shail M Govani Eric E Elliott Stacy B Menees Stephanie L Judd Sameer D Saini Constantinos P Anastassiades Annette L Urganus Suzanna J Boyce Philip S Schoenfeld | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，17： | 7 |
| 6 | 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 |
| 7 | It is safe to use transdermal glyceryl trinitrate to lower blood pressure in patients with acute ischaemic stroke with carotid stenosis显示文摘Background There is concern that blood pressure(BP)lowering in acute stroke may compromise cerebral perfusion and worsen outcome in the presence of carotid stenosis.We assessed the effect of glyceryl trinitrate(GTN)in patients with carotid stenosis using data from the Efficacy of Nitric Oxide in Stroke(ENOS)Trial.Methods ENOS randomised 4011 patients with acute stroke and raised systolic BP(140-220 mm Hg)to transdermal GTN or no GTN within 48 hours of onset.Those on prestroke antihypertensives were also randomised to stop or continue their medication for 7 days.The primary outcome was the modified Rankin Scale(mRS)at day 90.Ipsilateral carotid stenosis was split:<30%;30-<50%;50-<70%;≥70%.Data are ORs with 95%CIs adjusted for baseline prognostic factors.results 2023(60.5%)ischaemic stroke participants had carotid imaging.As compared with<30%,≥70%ipsilateral stenosis was associated with an unfavourable shift in mRS(worse outcome)at 90 days(OR 1.88,95%CI 1.44 to 2.44,p<0.001).Those with≥70%stenosis who received GTN versus no GTN had a favourable shift in mRS(OR 0.56,95%CI 0.34 to 0.93,p=0.024).In those with 50-<70%stenosis,continuing versus stopping prestroke antihypertensives was associated with worse disability,mood,quality of life and cognition at 90 days.Clinical outcomes did not differ across bilateral stenosis groups.Conclusions Following ischaemic stroke,severe ipsilateral carotid stenosis is associated with worse functional outcome at 90 days.GTN appears safe in ipsilateral or bilateral carotid stenosis,and might improve outcome in severe ipsilateral carotid stenosis. | Jason P Appleton Lisa J Woodhouse Andrew Belcher Daniel Bereczki Eivind Berge Valeria Caso Hui Meng Chang Hanne K Christensen Ronan Collins John Gommans Ann C Laska George Ntaios Serefnur Ozturk Gillian M Sare Szabolcs Szatmari Yongjun Wang Joanna M Wardlaw Nikola Sprigg Philip M Bath for the ENOS investigators | 2019 | Stroke & Vascular Neurology2019，4，1： | 6 |

| 10 | Dysfunctional stem and progenitor cells impair fracture healing with age显示文摘Successful fracture healing requires the simultaneous regeneration of both the bone and vasculature;mesenchymal stem cells (MSCs) are directed to replace the bone tissue, while endothelial progenitor cells (EPCs) form the new vasculature that supplies blood to the fracture site. In the elderly, the healing process is slowed, partly due to decreased regenerative function of these stem and progenitor cells. MSCs from older individuals are impaired with regard to cell number, proliferative capacity, ability to migrate, and osteochondrogenic differentiation potential. The proliferation, migration and function of EPCs are also compromised with advanced age. Although the reasons for cellular dysfunction with age are complex and multidimensional, reduced expression of growth factors, accumulation of oxidative damage from reactive oxygen species, and altered signaling of the Sirtuin-1 pathway are contributing factors to aging at the cellular level of both MSCs and EPCs. Because of these geriatric-specific issues, effective treatment for fracture repair may require new therapeutic techniques to restore cellular function. Some suggested directions for potential treatments include cellular therapies, pharmacological agents, treatments targeting age-related molecular mechanisms, and physical therapeutics. Advanced age is the primary risk factor for a fracture, due to the low bone mass and inferior bone quality associated with aging;a better understanding of the dysfunctional behavior of the aging cell will provide a foundation for new treatments to decrease healing time and reduce the development of complications during the extended recovery from fracture healing in the elderly. | Diane R Wagner Sonali Karnik Zachary J Gunderson Jeffery J Nielsen Alanna Fennimore Hunter J Promer Jonathan W Lowery M Terry Loghmani Philip S Low Todd O McKinley Melissa A Kacena Matthias Clauss Jiliang Li | 2019 | World Journal of Stem Cells2019，11，6： | 3 |

| 13 | Appropriateness of systemic treatments in unresectable metastatic well-differentiated pancreatic neuroendocrine tumors显示文摘AIM:To evaluate systemic treatment choices in unresectable metastatic well-differentiated pancreatic neuroendocrine tumors(PNETs)and provide consensus treatment recommendations.METHODS:Systemic treatment options for pancreatic neuroendocrine tumors have expanded in recent years to include somatostatin analogs,angiogenesis inhibitors,inhibitors of mammalian target of rapamycinand cytotoxic agents.At this time,there is little data to guide treatment selection and sequence.We therefore assembled a panel of expert physicians to evaluate systemic treatment choices and provide consensus treatment recommendations.Treatment appropriateness ratings were collected using the RAND/UCLA modified Delphi process.After studying the literature,a multidisciplinary panel of 10 physicians assessed the appropriateness of various medical treatment scenarios on a 1-9 scale.Ratings were done both before and after an extended discussion of the evidence.Quantitative measurements of agreement were made and consensus statements developed from the second round ratings.RESULTS:Specialties represented were medical and surgical oncology,interventional radiology,and gastroenterology.Panelists had practiced for a mean of15.5 years(range:6-33).Among 202 rated scenarios,disagreement decreased from 13.2%(26 scenarios)before the face-to-face discussion of evidence to 1%(2)after.In the final ratings,46.5%(94 scenarios)were rated inappropriate,21.8%(44)were uncertain,and30.7%(62)were appropriate.Consensus statements from the scenarios included:(1)it is appropriate to use somatostatin analogs as first line therapy in patients with hormonally functional tumors and may be appropriate in patients who are asymptomatic;(2)it is appropriate to use everolimus,sunitinib,or cytotoxic chemotherapy therapy as first line therapy in patients with symptomatic or progressive tumors;and(3)beyond first line,these same agents can be used.In patients with uncontrolled secretory symptoms,octreotide LAR doses can be titrated up to 60 mg every4 wk or up to 40 mg every 3 or 4 wk.CONCLUSION:Using the Delphi process allowed physician experts to systematically obtain a consensus on the appropriateness of a variety of medical therapies in patients with PNETs. | Jonathan R Strosberg George A Fisher Al B Benson Lowell B Anthony Bulent Arslan John F Gibbs Edward Greeno Renuka V Iyer Michelle K Kim William J Maples Philip A Philip Edward M Wolin Dasha Cherepanov Michael S Broder | 2015 | World Journal of Gastroenterology2015，21，8： | 2 |

| 16 | Is the schatzki ring a unique esophageal entity?显示文摘AIM:To study,whether the association of Schatzki rings with other esophageal disorders support one of the theories about its etiology.METHODS:From 1987 until 2007,all patients with newly diagnosed symptomatic Schatzki rings (SRs) were prospectively registered and followed.All of them underwent structured interviews with regards to clinical symptoms,as well as endoscopic and/or radiographic examinations.Endoscopic and radiographic studies determined the presence of an SR and additional morphological abnormalities.RESULTS:One hundred and sixty-seven patients (125 male,42 female) with a mean age of 57.1±14.6 years were studied.All patients complained of intermittent dysphagia for solid food and 113 (79.6%) patients had a history of food impaction.Patients experienced symptoms for a mean of 4.7±5.2 years before diagnosis.Only in 23.4% of the 64 patients who had endoscopic and/or radiological examinations before their first presentation to our clinic,was the SR previously diagnosed.At presentation,the mean ring diameter was 13.9±4.97 mm.One hundred and sixty-two (97%) patients showed a sliding hiatal hernia.Erosive reflux esophagitis was found in 47 (28.1%) patients.Twenty-six (15.6%) of 167 patients showed single or multiple esophageal webs;five (3.0%) patients exhibited eosinophilic esophagitis;and four (2.4%) had esophageal diverticula.Four (7%) of 57 patients undergoing esophageal manometry had nonspecific esophageal motility disorders.CONCLUSION:Schatzki rings are frequently associated with additional esophageal disorders,which support the assumption of a multifactorial etiology.Despite typical symptoms,SRs might be overlooked. | Michaela Müller Ines Gockel Philip Hedwig Alexander J Eckardt Kathrin Kuhr Jochem Knig Volker F Eckardt | 2011 | World Journal of Gastroenterology2011，17，23： | 2 |

| 19 | Tooth loss and alveolar remodeling in Sinosaurus triassicus (Dinosauria: Theropoda) from the Lower Jurassic strata of the Lufeng Basin, China显示文摘Pathological or traumatic loss of teeth often results in the resorption and remodeling of the affected alveoli in mammals. However, instances of alveolar remodeling in reptiles are rare. A remodeled alveolus in the maxilla of the Chinese theropod Sinosaurus (Lower Jurassic Lower Lufeng Formation) is the first confirmed example of such dental pathology in a dinosaur. Given the known relationship between feeding behavior and tooth damage in theropods (teeth with spalled enamel, tooth crowns embedded in bone) and the absence of dentary, maxillary, and premaxillary osteomyelitis, traumatic loss of a tooth is most likely the cause of alveolar remodeling. Based on the extent of remodeling, the injury and subsequent tooth loss were non-fatal in this individual. | XING LiDa BELL Phil R ROTHSCHILD Bruce M RAN Hao ZHANG JianPing DONG ZhiMing ZHANG Wei CURRIE Philip J | 2013 | Chinese Science Bulletin2013，58，16： | 2 |
