| 1 | Blood glucose changes surrounding initiation of tumor-necrosis factor inhibitors and conventional disease-modifying anti-rheumatic drugs in veterans with rheumatoid arthritis显示文摘AIM To determine the scope of acute hypoglycemic effects for certain anti-rheumatic medications in a large retrospective observational study. METHODS Patients enrolled in the Veterans Affairs Rheumatoid Arthritis (VARA) registry were selected who, during follow-up, initiated treatment with tumor necrosis factor inhibitors (TNFi's, including etanercept, adalimumab, infliximab, golimumab, or certolizumab), prednisone, or conventional disease-modifying anti-rheumatic drugs(DMARDs), and for whom proximate random blood glucose (RBG) measurements were available within a window 2-wk prior to, and 6 mo following, medication initiation. Similar data were obtained for patients with proximate values available for glycosylated hemoglobin A1C values within a window 2 mo preceding, and 12 mo following, medication initiation. RBG and A1C measurements were compared before and after initiation events using paired t-tests, and multivariate regression analysis was performed including established comorbidities and demographics.RESULTS Two thousands one hundred and eleven patients contributed at least one proximate measurement surrounding the initiation of any examined medication. A significant decrease in RBG was noted surrounding 653 individual hydroxychloroquine-initiation events(-3.68 mg/dL, P = 0.04), while an increase was noted for RBG surrounding 665 prednisone-initiation events(+5.85 mg/d L, P < 0.01). A statistically significant decrease in A1C was noted for sulfasalazine initiation, as measured by 49 individual initiation events(-0.70%, P < 0.01). Multivariate regression analyses, using methotrexate as the referent, suggest sulfasalazine (β =-0.58, P = 0.01) and hydroxychloroquine(β =-5.78, P = 0.01) use as predictors of lower post-medicationinitiation RBG and A1C values, respectively. Analysis by drug class suggested prednisone (or glucocorticoids) as predictive of higher medication-initiation event RBG among all start events as compared to DMARDs, while this analysis did not show any drug class-level effect for TNFi. A diagnosis of congestive heart failure(β = 4.69, P = 0.03) was predictive for higher post-initiation RBG values among all medication-initiation events.CONCLUSION No statistically significant hypoglycemic effects surrounding TNFi initiation were observed in this large cohort. Sulfasalazine and hydroxychloroquine may have epidemiologically significant acute hypoglycemic effects. | Patrick R Wood Evan Manning Joshua F Baker Bryant England Lisa Davis Grant W Cannon Ted R Mikuls Liron Caplan | 2018 | World Journal of Diabetes2018，9，2： | 8 |
| 2 | Epidemiology of inflammatory bowel disease in South America: A systematic review显示文摘BACKGROUND The worldwide epidemiology of inflammatory bowel disease(IBD)is rapidly changing.Increasing Crohn’s disease(CD)and ulcerative colitis(UC)incidence and prevalence have been recorded in developing regions such as Asia,Africa and Eastern Europe where it was previously thought to be uncommon.Whether this is also the case in South America is not well known.Demonstration that developing regions worldwide have increasing IBD incidence would indicate that environmental change plays a significant role in the development of IBD.AIM To report the incidence,prevalence and disease characteristics of CD and UC within the South American continent.METHODS A systematic review was conducted by searching published studies in major international and regional databases(MEDLINE,EMBASE and Scopus)between January 1990 and December 2018.Outcomes considered were incidence,prevalence,phenotype,environmental and genetic factors,ethnicity and gender.A pair of independent reviewers screened and reviewed all identified articles.RESULTS One hundred and sixty two citations were initially retrieved with 18 studies included in this systematic review.The majority of included studies were from Brazil(n=13,72%).The incidence of UC ranged from 4.3-5.3/100000 personyears whilst the incidence of CD ranged from 0.74-3.5/100000 person-years.Prevalence ranged from 15.0-24.1/100000 inhabitants for UC and from 2.4-14.1/100000 inhabitants for CD.The incidence and prevalence of both UC and CD has increased significantly in Brazil over the past 21 years.Pancolitis was the most common disease distribution in patients with UC whilst colonic involvement was the most common distribution in CD.People residing in urban areas were at higher risk of developing both CD and UC.CONCLUSION The IBD burden in South America is increasing at a rate possibly even greater than other developing regions around the world.There is a paucity of highquality epidemiological studies and further robust and representative data are required to further explore modifiable risk factors and disease phenotypes. | Sriharan Selvaratnam Santiago Gullino Lisa Shim Eric Lee Alice Lee Sudarshan Paramsothy Rupert W Leong | 2019 | World Journal of Gastroenterology2019，25，47： | 5 |
| 3 | Iron increases HMOX1 and decreases hepatitis C viral expression in HCV-expressing cells显示文摘AIM:To investigate effects of iron on oxidative stress, heme oxygenase-1(HMOX1)and hepatitis C viral(HCV) expression in human hepatoma cells stably expressing HCV proteins. METHODS:Effects of iron on oxidative stress,HMOX1, and HCV expression were assessed in CON1 cells. Measurements included mRNA by quantitative reverse transcription-polymerase chain reaction,and protein levels by Western blots. RESULTS:Iron,in the form of ferric nitrilotriacetate,increased oxidative stress and up-regulated HMOX1 gene expression.Iron did not affect mRNA or protein levels of Bach1,a repressor of HMOX1.Silencing the up-regulation of HMOX1 nuclear factor-erythroid 2-related factor 2(Nrf2)by Nrf2-siRNA decreased FeNTA-mediated up-regulation of HMOX1 mRNA levels.These iron effects were completely blocked by deferoxamine(DFO).Iron also significantly decreased levels of HCV core mRNA and protein by 80%-90%, nonstructural 5A mRNA by 90%and protein by about 50%in the Con1 full length HCV replicon cells, whereas DFO increased them. CONCLUSION:Excess iron up-regulates HMOX1 and down-regulates HCV gene expression in hepatoma cells.This probably mitigates liver injury caused by combined iron overload and HCV infection. | Wei-Hong Hou Lisa Rossi Ying Shan Jian-Yu Zheng Richard W Lambrecht Herbert L Bonkovsky | 2009 | World Journal of Gastroenterology2009，15，36： | 5 |
| 4 | Multiband emission from single β-NaYF_(4)(Yb,Er) nanoparticles at high excitation power densities and comparison to ensemble studies显示文摘Ensemble and single particle studies of the excitation power density (P)-dependent upconversion luminescence (UCL) of core and core-shell β-NaYF_(4):Yb,Er upconversion nanoparticles (UCNPs) doped with 20% Yb^(3+) and 1% or 3% Er^(^(3+)) performed over a P regime of 6 orders of magnitude reveal an increasing contribution of the emission from high energy Er^(3+) levels at P > 1 kW/cm^(2). This changes the overall emission color from initially green over yellow to white. While initially the green and with increasing P the red emission dominate in ensemble measurements at P < 1 kW/cm^(2), the increasing population of higher Er^(^(3+)) energy levels by multiphotonic processes at higher P in single particle studies results in a multitude of emission bands in the ultraviolet/visible/near infrared (UV/vis/NIR) accompanied by a decreased contribution of the red luminescence. Based upon a thorough analysis of the P-dependence of UCL, the emission bands activated at high P were grouped and assigned to 2–3, 3–4, and 4 photonic processes involving energy transfer (ET), excited-state absorption (ESA), cross-relaxation (CR), back energy transfer (BET), and non-radiative relaxation processes (nRP). This underlines the P-tunability of UCNP brightness and color and highlights the potential of P-dependent measurements for mechanistic studies required to manifest the population pathways of the different Er^(3+) levels. | Florian Frenzel Christian Würth Oleksii Dukhno Frédéric Przybilla Lisa MWiesholler Verena Muhr Thomas Hirsch Yves Mély Ute Resch-Genger | 2021 | Nano Research2021，14，11： | 3 |
| 5 | 一种房颤风险评分系统的建立(Framingham心脏研究):基于社区的队列研究显示文摘背景房颤导致了发病率和病死率的显著上升。本研究旨在建立一种预测个体罹患房颤绝对风险的风险评分系统,并提供研究人员评价新危险因素的流程。方法作者评估了Framingham心脏研究中于1968年6月至1987年9月间进行了8044次检测的4764例参与者(55%为女性,年龄45~95岁)。此后,参与者被随访至房颤首发,随访期最长达10年。多变量Coxi回归确认出1(1年内罹患房颤的临床危险因素。次级分析纳入了常规超声心动图检测指标(5152例4参与者,7156次检测)对房颤风险进行再分层评估,并评价超声检测指标能否提高风险预测能力。结果4764例参与者中的457例4(10%)罹患房颤。年龄、性别、体重指数、收缩压、降压治疗、PR间期、有临床意义的心脏杂音及心力衰竭与房颤相关,并被纳入了风险评分模型(除体重指数P=0.08外,其余均为P〈0.05),模型的C统计量为0.78(95%CI0.76~0.80)。10年房颤风险随年龄变化:年龄〈65岁的人群中53例(1%)风险高于15%,而〉65岁的人群中为783例(27%)。为提高预测能力而纳入超声检测指标仅使模型C统计量略微增高,由0.78(95%C10.75~0.80)增至0.79(95%CI0.77~0.82:P=0.005)。超声心动图检测指标并不能改善风险再分层评估(P=0.18)。结论基于社区医疗中易得的临床因素建立的风险评分系统,有助于确认社区个体罹患房颤的风险,评估技术或标志物能否改善风险预测,以及针对高危个体采取预防措施。 | Renate B Schnabel Lisa M Sullivan Daniel Levy Michael J Pencina Joseph M Massaro Ralph B D'Agostino Sr Christopher Newton-Cheh Jennifer F Yamamoto Jared W Magnani Thomas M Tadros William B Kannel Thomas J Wang Patrick T Ellinor Philip A Wolf Ramachanclran S Vasan Emelia J Benjamin 黄刚(译) | 2009 | 世界临床医学2009，，9： | 2 |
| 6 | Analysis of the nitric oxide-cyclic guanosine monophosphate pathway in experimental liver cirrhosis suggests phosphodiesterase-5 as potential target to treat portal hypertension显示文摘AIM To investigate the potential effect of inhibitors of phosphodiesterase-5(PDE-5) for therapy of portal hypertension in liver cirrhosis.METHODS In the rat model of thioacetamide-induced liver fibrosis/cirrhosis the nitric oxide-cyclic guanosine monophosphate(NO-cGMP) pathway was investigated. Expression and localization of PDE-5, the enzyme that converts vasodilating cGMP into inactive 5'-GMP, was in the focus of the study. Hepatic gene expression of key components of the NO-cGMP pathway was determined by qRT-PCR: Endothelial NO synthase(eNOS), inducible NO synthase(iNOS), soluble guanylate cyclase subunits α1 and β1(sGCa1, sGCb1), and PDE-5. Hepatic PDE-5 protein expression and localization were detected by immunohistochemistry. Serum cGMP concentrations were measured using ELISA. Acute effects of the PDE-5 inhibitor Sildenafil(0.1 mg/kg or 1.0 mg/kg) on portal and systemic hemodynamics were investigated using pressure transducers.RESULTS Hepatic gene expression of eNOS(2.2-fold; P = 0.003), sGCa1(1.7-fold; P = 0.003), sGCb1(3.0-fold; P = 0.003), and PDE-5(11-fold; P = 0.003) was increased in cirrhotic livers compared to healthy livers. Overexpression of PDE-5(7.7-fold; P = 0.006) was less pronounced in fibrotic livers. iNOS expression was only detected in fibrotic and cirrhotic livers. In healthy liver, PDE-5 protein was localized primarily in zone 3 hepatocytes and to a lesser extent in perisinusoidal cells. This zonation was disturbed in cirrhosis: PDE-5 protein expression in perisinusoidal cells was induced approximately 8-fold. In addition, PDE-5-expressing cells were also found in fibrous septa. Serum cGMP concentrations were reduced in rats with cirrhotic livers by approximately 40%. Inhibition of PDE-5 by Sildenafil caused a significant increase in serum cGMP concentrations [+ 64% in healthy rats(P = 0.024), + 85% in cirrhotic rats(P = 0.018)]. Concomitantly, the portal venous pressure was reduced by 19% in rats with liver cirrhosis. CONCLUSION Overexpression and abrogated zonation of PDE-5 likely contribute to the pathogenesis of cirrhotic portal hypertension. PDE-5 inhibition may therefore be a reasonable therapeutic approach for portal hypertension. | Denise Schaffner Adhara Lazaro Peter Deibert Peter Hasselblatt Patrick Stoll Lisa Fauth Manfred W Baumstark Irmgard Merfort Annette Schmitt-Graeff Wolfgang Kreisel | 2018 | World Journal of Gastroenterology2018，24，38： | 2 |
