1慢性炎症、肿瘤微环境与癌变显示文摘某些肿瘤发生前或发生时常有慢性炎症。抗炎疗法在癌症的预防及治疗中也显现出一定的疗效。创伤愈合演变为癌症前兆的具体机理已成为当前研究的热点。已有研究证实,炎症介质、炎症相关基因多态性与癌变之间存在病原学关系。潜在的炎症过程可通过不同的机理影响肿瘤间室与癌症分期,Tamas A. Gonda Shuiping Tu Timothy C. Wang 丁燕(翻译) 南娟(翻译) 刘谦(校对) 2009中国肺癌杂志2009,12,9:55
2Perianal disease,small bowel disease,smoking,prior steroid or early azathioprine/biological therapy are predictors of disease behavior change in patients with Crohn's disease显示文摘AIM:To assess the combined effect of disease phenotype, smoking and medical therapy [steroid, azathioprine(AZA), AZA/biological therapy] on the probability of disease behavior change in a Caucasian cohort of patients with Crohn's disease(CD).METHODS:Three hundred and forty well-characterized, unrelated, consecutive CD patients were analyzed(M/F:155/185, duration:9.4 ± 7.5 years) with a complete clinical follow-up.Medical records including disease phenotype according to the Montreal classification, extraintestinal manifestations, use of medications and surgical events were analyzed retrospectively.Patients were interviewed on their smoking habits at the time of diagnosis and during the regular follow-up visits.RESULTS:A change in disease behavior was observed in 30.8% of patients with an initially non-stricturing, non-penetrating disease behavior after a mean diseaseduration of 9.0 ± 7.2 years.In a logistic regression analysis corrected for disease duration, perianal disease, smoking, steroid use, early AZA or AZA/ biological therapy use were independent predictors of disease behavior change.In a subsequent Kaplan-Meier survival analysis and a proportional Cox regression analysis, disease location(P = 0.001), presence of perianal disease(P < 0.001), prior steroid use(P = 0.006), early AZA(P = 0.005) or AZA/biological therapy(P = 0.002), or smoking(P = 0.032) were independent predictors of disease behavior change.CONCLUSION:Our data suggest that perianal disease, small bowel disease, smoking, prior steroid use, early AZA or AZA/biological therapy are all predictors of disease behavior change in CD patients.Peter Laszlo Lakatos Zsofia Czegledi Tamas Szamosi Janos Banai Gyula David Ferenc Zsigmond Tunde Pandur Zsuzsanna Erdelyi Orsolya Gemela Janos Papp Laszlo Lakatos 2009World Journal of Gastroenterology2009,15,28:14
3Toll-like receptor 4 and NOD2/CARD15 mutations in Hungarian patients with Crohn's disease: Phenotype-genotype correlations显示文摘AIM: To determine common NOD2/CARD15 mutations and TLR4 D299G polymorphism in Hungarian patients with CD.METHODS: A total of 527 unrelated patients with CD (male/female: 265/262, age: 37.1 (SD 7.6) years) and 200 healthy subjects were included. DNA was screened for possible NOD2/CARD15 mutations by denaturing highperformance liquid chromatography (confirmed by direct sequencing). TLR4 D299G was tested by PCR-RFLP.RESULTS: NOD2/CARD15 mutations were found in 185patients (35.1%) and in 33 controls (16.5%, P<0.0001).SNP8/R702W (10.8% vs 6%, P = 0.02), SNP13/3020insC (19.4% vs 5%, P<0.0001) and exon4 R703C (2.1% vs 0%, P = 0.02) mutations were more frequent in CD, while the frequency of SNP12/G908R was not increased. The frequency of TLR4 D299G was not different (CD: 9.9% vscontrols: 12.0%). Variant NOD2/CARD15 allele was associated with an increased risk for CD (ORhet = 1.71,95%CI = 1.12-2.6, P= 0.0001, ORtwo-riskalleles = 25.2,95%CI = 4.37- , P<0.0001), early disease onset (carrier:26.4 years vs non-carrier: 29.8 years, P = 0.0006), ileal disease (81.9% vs 69.5%, OR = 1.99, 95%CI = 1.29-3.08,P = 0.02, presence of NOD2/CARD15 and TLR4: 86.7% vs64.8%), stricturing behavior (OR = 1.69, 95%CI = 1.13-2.55,P = 0.026) and increased need for resection (OR=1.71,95%CI: 1.13-2.62, P= 0.01), but not with duration, extraintestinal manifestations, familial disease or smoking. TLR4exhibited a modifier effect: age of onset in wt/TLR4 D299G carriers: 27.4 years vs NOD2mut/TLR D299G: 23 years (P= 0.06), in NOD2mut/wt: 26.7 years.CONCLUSION: These results confirm that variant NOD2/CARD15 (R702W, R703C and 3020insC) alleles are associated with earlier disease onset, ileal disease,stricturing disease behavior in Hungarian CD patients. In contrast, although the frequency of TLR4 D299G polymorphism was not different from controls, NOD2/TLR4mutation carriers tended to present at earlier age.Peter Laszlo Lakatos Laszlo Lakatos Ferenc Szalay Claudia Willheim-Polli Christoph (O|¨)sterreicher Zsolt Tulassay Tamas Molnar Walter Reinisch Janos Papp Gyula Mozsik Hungarian IBD Study Group Peter Ferenci 2005World Journal of Gastroenterology2005,11,10:14
4Effect of melatonin on the severity of L-arginine-induced experimental acute pancreatitis in rats显示文摘瞄准:决定 melatonin 预告的处理的效果并且在 L 精氨酸(L-Arg ) 的严厉上处理以后在老鼠的导致的试验性的胰腺炎。方法:男 Wistar 老鼠(25 ) 被划分成五个组。那些在 1h 的间隔在组 A 收到了 3.2g/kg 体重 L-Arg i.p 的二注射。在组麻省,老鼠与 50 mg/kg 体重 melatonin i.p 被对待在 L-Arg 管理以前的 30 min。在组 AM,在 L-Arg 被给以后,老鼠收到了 melatonin 1h 的一样的剂量。在组 M, melatonin 的单次量是以前描述了被管理。在组 C,对照动物收到了生理盐水注射 i.p 所有老鼠被给在第二 L-Arg 注射以后的 24 h。结果:引起严重引起坏死胰腺炎的 L-Arg 管理在浆液淀粉酶水平,胰腺的重量 / 身体重量比率(pw/bw ) ,胰腺的 IL-6 内容和 myeloperoxidase 由重要举起证实了活动,相对控制值。浆液淀粉酶水平的举起显著地在与仅仅与 L-Arg 注射的老鼠相比给 melatonin 追随者 L-Arg 的老鼠被减少。胰腺的抗氧化剂酶(Cu/Zn-superoxide 歧化酶(Cu/Zn-SOD ) 和过氧化氢酶(猫)) 的活动显著地被增加在胰腺炎以后的 24 h 感应。显著地在 L-Arg 之前给的 Melatonin 在独自与 L-Arg 对待的老鼠相对那减少了胰腺的猫活动。在肝, L-Arg 显著地每氧化水平,和谷胱甘肽过氧化物酶和 Cu/Zn-SOD 活动增加了类脂化合物,而 Mn 草皮活动作为与控制老鼠相比被减少。Melatonin 预告的处理阻止了这些变化。结论:Melatonin 是能在尖锐胰腺炎期间抵抗一些 L-Arg-induced 变化的一种抗氧化剂,并且可能因此在有尖锐引起坏死胰腺炎的病人的支持的治疗有用。Annamaria Szabolcs Russel J Reiter Tamas Letoha Peter Hegyi Gabor Papai Ilona Varga Katalin Jarmay Jozsef Kaszaki Reka Sari Zoltan Rakonczay Jr Janos Lonovics Tamas Takacs 2006World Journal of Gastroenterology2006,12,2:13
5Smoking in inflammatory bowel diseases:Good,bad or ugly?显示文摘吸烟是在煽动性的肠疾病(IBD ) 的一个重要环境因素,有在 ulcerative (UC ) 和 Crohn'disease (CD ) 的不同效果。最近的元分析部分证实了那支吸烟被发现对 ulcerative 保护的以前的调查结果,减少并且在疾病的发作以后,可能改进它的功课对结肠切除术的需要。然而,吸烟增加开发 CD 的风险并且变得更坏它的功课,为类固醇,抑制免疫力的药和重新操作增加需要。吸烟停止加重 ulcerative 并且改进 CD。数据是不管多么,象涉及这种双关系的潜在的机制一样大部分矛盾仍然是未知的。在这篇评论文章,作者考察在煽动性的肠疾病吸烟的角色。Peter Laszlo Lakatos Tamas Szamosi Laszlo Lakatos 2007World Journal of Gastroenterology2007,13,46:11
6Presepsin teardown- pitfalls of biomarkers in the diagnosis and prognosis of bacterial infection in cirrhosis显示文摘AIM To evaluate the diagnostic and prognostic value of presepsin in cirrhosis-associated bacterial infections. METHODS Two hundred and sixteen patients with cirrhosis were enrolled. At admission, the presence of bacterial infections and level of plasma presepsin, serum C-reactive protein(CRP) and procalcitonin(PCT) were evaluated. Patients were followed for three months to assess the possible association between presepsin level and short-term mortality.RESULTS Present 34.7 of patients had bacterial infection. Presepsin levels were significantly higher in patients with infection than without(median, 1002 pg/m L vs 477 pg/m L, P < 0.001), increasing with the severity of infection [organ failure(OF): Yes vs No, 2358 pg/m L vs 710 pg/m L, P < 0.001]. Diagnostic accuracy of presepsin for severe infections was similar to PCT and superior to CRP(AUC-ROC: 0.85, 0.85 and 0.66, respectively, P = NS for presepsin vs PCT and P < 0.01 for presepsin vs CRP). At the optimal cut-off value of presepsin > 1206 pg/m L sensitivity, specificity, positive predictive values and negative predictive values were as follows: 87.5%, 74.5%, 61.8% and 92.7%. The accuracy of presepsin, however, decreased in advanced stage of the disease or in the presence of renal failure, most probably because of the significantly elevated presepsin levels in non-infected patients. 28-d mortality rate was higher among patients with > 1277 pg/m L compared to those with ≤ 1277 pg/m L(46.9% vs 11.6%, P < 0.001). In a binary logistic regression analysis, however, only PCT(OR = 1.81, 95%CI: 1.09-3.01, P = 0.022) but neither presepsin nor CRP were independent risk factor for 28-d mortality after adjusting with MELD score and leukocyte count.CONCLUSION Presepsin is a valuable new biomarker for defining severe infections in cirrhosis, proving same efficacy as PCT. However, it is not a useful marker of short-term mortality.Maria Papp Tamas Tornai Zsuzsanna Vitalis Istvan Tornai David Tornai Tamas Dinya Andrea Sumegi Peter Antal-Szalmas 2016World Journal of Gastroenterology2016,22,41:9
7新疆北部白冠攀雀的巢与巢址选择显示文摘2008年4—7月,在新疆北部对白冠攀雀巢址选择进行了研究。白冠攀雀的营巢习性特殊,巢呈囊袋状,结构甚为精致。对于白冠攀雀巢的研究,采用总面积调查法,进行地毯式的搜寻,并结合标图法对其进行标记,绘制分布图。研究结果共发现巢125个,营巢位于于临近湖泊、河流等水域附近的柳树、杨树、桦树等阔叶树上。营巢树种以柳树为主,占68.80%。巢的高度平均为(5.3±2.5)m,营巢于乔木的中下部(约1/3处),约70%的巢离河边不足30m。对于巢址选择的研究,将原始记录中与巢址选择有关的特征变量进行主成分分析,分析表明,影响白冠攀雀巢址选择的主要因素有4种,依次为:郁闭度因素(包括营巢树胸径、巢上郁闭度)、营巢树种因素(包括营巢树种、树高、巢位高度和乔木种类)、方位因素(包括距河边距离和巢向)、食物与巢材因素。梅宇 马鸣 胡宝文 Dusan Brinkhuizen Tamas Szekely 2009Zoological Research2009,30,5:7
8Staging of portal hypertension and portosystemic shunts using dynamic nuclear medicine investigations显示文摘AIM: To explore portal hypertension and portosys-temic shunts and to stage chronic liver disease (CLD) based on the pathophysiology of portal hemodynam-ics. METHODS: Per-rectal portal scintigraphy (PRPS) was performed on 312 patients with CLD and liver angio-scintigraphy (LAS) on 231 of them. The control group included 25 healthy subjects. We developed a new model of PRPS interpretation by introducing two new parameters,the liver transit time (LTT) and the circu-lation time between right heart and liver (RHLT). LTT for each lobe was used to evaluate the early portal hypertension. RHLT is useful in cirrhosis to detect liver areas missing portal in? ow. We calculated the classical per-rectal portal shunt index (PRSI) at PRPS and the hepatic perfusion index (HPI) at LAS. RESULTS: The normal LTT value was 24 ± 1 s. Abnor-mal LTT had PPV = 100% for CLD. Twenty-seven non-cirrhotic patients had LTT increased up to 35 s (median 27 s). RHLT (42 ± 1 s) was not related to liver disease. Cirrhosis could be excluded in all patients with PRSI < 5% (P < 0.01). PRSI > 30% had PPV = 100% for cirrhosis. Based on PRPS and LAS we propose the clas-sifi cation of CLD in 5 hemodynamic stages. Stage 0 is normal (LTT = 24 s,PRSI < 5%). In stage 1,LTT is increased,while PRSI remains normal. In stage 2,LTT is decreased between 16 s and 23 s,whereas PRSI is increased between 5% and 10%. In stage 3,PRSI is increased to 10%-30%,and LTT becomes undetect-able by PRPS due to the portosystemic shunts. Stage 4 includes the patients with PRSI > 30%. RHLT and HPI were used to subtype stage 4. In our study stage 0 had NPV = 100% for CLD,stage 1 had PPV = 100% for non-cirrhotic CLD,stages 2 and 3 represented the transition from chronic hepatitis to cirrhosis,stage 4 had PPV = 100% for cirrhosis. CONCLUSION: LTT allows the detection of early por-tal hypertension and of opening of transhepatic shunts. PRSI is useful in CLD with extrahepatic portosystemic shunts. Our hemodynamic model stages the evolution of portal hypertension and portosystemic shunts. It may be of use in the selection of patients for interferon therapy.Mircea Dragoteanu Ioan A Balea Liliana A Dina Cecilia D Piglesan Ioana Grigorescu Stefan Tamas Sabin O Cotul 2008World Journal of Gastroenterology2008,14,24:7
9Diagnostic and therapeutic biomarkers in pancreaticobiliary malignancy显示文摘Pancreatic ductal adenocarcinoma(PDAC) and cholangiocarcinoma(CCA) are two malignancies that carry significant morbidity and mortality. The poor prognoses of these cancers are strongly related to lack of effective screening modalities as well as few therapeutic options. In this review, we highlight novel biomarkers that have the potential to be used as diagnostic, prognostic and predictive markers. The focus of this review is biomarkers that can be evaluated on endoscopically-obtained biopsies or brush specimens in the pre-operative setting. We also provide an overview of novel serum based markers in the early diagnosis of both PDAC and CCA. In pancreatic cancer, the emphasis is placed on prognostic and theranostic markers, whereas in CCA the utility of molecular markers in diagnosis and prognosis are highlighted.Domenico Viterbo Valerie Gausman Tamas Gonda 2016World Journal of Gastrointestinal Endoscopy2016,8,3:6
10Overview and comparison of guidelines for management of pancreatic cystic neoplasms显示文摘Pancreatic cysts are identified at an increasing frequency.Although mucinous cystic neoplasms represent a pre-malignant condition,the majority of these lesions do not progress to cancer.Over the last 10 years several societies have established guidelines for the diagnosis,initial evaluation and surveillance of these lesions.Here we provide an overview of five commonly used guidelines:2015 American Gastroenterological Association,2017 International Association of Pancreatology,American College of Gastroenterology 2018,European Study Group and American College of Radiology.We describe the similarities and differences between the methods used to formulate these guidelines,the population they target and their approaches towards initial evaluation and surveillance of cystic lesions.Aws Hasan Kavel Visrodia James J Farrell Tamas A Gonda 2019World Journal of Gastroenterology2019,25,31:5
11Gut barrier failure biomarkers are associated with poor disease outcome in patients with primary sclerosing cholangitis显示文摘AIM To assess the prevalence of a panel of serologic markers that reflect gut barrier dysfunction in a mixed cohort of pediatric and adult primary sclerosing cholangitis(PSC) patients.METHODS Sera of 67 PSC patients [median age(range): 32(5-79) years, concomitant IBD: 67% and cirrhosis: 20%] were assayed for the presence of antibodies against to F-actin(AAA Ig A/Ig G) and gliadin(AGA Ig A/Ig G)] and for serum level of intestinal fatty acid-binding protein(I-FABP) by ELISA. Markers of lipopolysaccharide(LPS) exposure [LPS binding protein(LBP)] and various antimicrobial antibodies [anti-OMP Plus Ig A and endotoxin core Ig A antibody(Endo CAb)] were also determined. Poor disease outcome was defined as orthotopic liver transplantation and/or liver-related death during the follow-up [median: 99(14-106) mo]. One hundred and fifty-three healthy subjects(HCONT) and 172 ulcerative colitis(UC) patients were the controls. RESULTS A total of 28.4%, 28.0%, 9% and 20.9% of PSC patients were positive for AAA Ig A, AAA Ig G, AGA Ig A and AGA Ig G, respectively. Frequencies of AAA Ig A and AAA Ig G(P < 0.001, for both) and AGA Ig G(P = 0.01, for both) but not AGA Ig A were significantly higher compared to both of the HCONT and the UC groups. In survival analysis, AAA Ig A-positivity was revealed as an independent predictor of poor disease outcome after adjusting either for the presence of cirrhosis [HR = 5.15(1.27-20.86), P = 0.022 or for the Mayo risk score(HR = 4.24(0.99-18.21), P = 0.052]. AAA Ig A-positivity was significantly associated with higher frequency of antimicrobial antibodies(P < 0.001 for Endo Cab Ig A and P = 0.012 for anti-OMP Plus Ig A) and higher level of the enterocyte damage marker(median I-FABP_(AAA Ig A pos vs neg): 365 vs 166 pg/m L, P = 0.011), but not with serum LBP level. CONCLUSION Presence of Ig A type AAA identified PSC patients with progressive disease. Moreover, it is associated with enhanced mucosal immune response to various microbial antigens and enterocyte damage further highlighting the importance of the gut-liver interaction in PSC.Tamas Tornai Eszter Palyu Zsuzsanna Vitalis Istvan Tornai David Tornai Peter Antal-Szalmas Gary L Norman Zakera Shums Gabor Veres Antal Dezsofi Gabriella Par Alajos Par Peter Orosz Ferenc Szalay Peter Laszlo Lakatos Maria Papp 2017World Journal of Gastroenterology2017,23,29:5
12西北干旱区农田春小麦蒸散量的空间插值方法显示文摘综合运用传统统计分析方法和地质统计分析方法,研究了西北旱区春小麦蒸散量在不同生育阶段的时空变异特征,并分析了试验区表层土壤储水量和叶面积指数对春小麦蒸散量的影响关系,通过分析比较,筛选表层土壤储水量为协同因子,并将其应用到试验区春小麦蒸散量的空间插值研究中。研究结果表明:在所研究的条件下,即使外观较为均匀、面积相对较小的农田,春小麦蒸散量仍具有较高的空间变异(变异系数范围0.328~0.495);当降雨入渗深度小于20cm时,表层土壤储水量(0—20cm)是影响研究区春小麦蒸散量变异的主要因子,春小麦不同生育期累积蒸散量与表层土壤储水量变化的相关系数在0.8—0.9之间,远大于春小麦累积蒸散量与叶面积指数的相关系数;基于表层土壤储水量的蒸散量协同克里金空间插值分析与地面实测结果相比,仅42个蒸散量地面采样数据即可保证研究区春小麦蒸散量估计精度高于90%。王春梅 孟庆岩 占玉林 刘苗 王靓 Tamas Jancso 2014农业机械学报2014,45,11:4
13Pulmonary embolization as primary manifestation of hepatocellular carcinoma with intracardiac penetration: A case report显示文摘Intracardiac manifestation of hepatocellular carcinoma (HCC) is a rare condition and an uncommon finding even at autopsy. Pulmonary tumor embolism as a presenting feature of HCC has been published only twice previously.In our case report, a 63-year-old man presented with high fever and six episodes of recurrent pneumonias during the last half year. Echocardiography was performed, a solid mass was found in the right atrium. Transesophageal echocardiography proved a tumor mass in the inferior vena cava (ⅣC) extending into the right atrium, abdominal ultrasound revealed tumor mass in the ⅣC and a solid tumor in the liver. Combined liver and heart surgery was attempted in order to remove the tumor mass from both the liver and the right atrium. Acute cor pulmonale occurred during tumor removal from the right atrium and the patient expired. In addition to local factors the possibility of embolization should arise in the background of recurrent pneumonia. Occult carcinoma must be included in possible causes of recurrent pulmonary embolism. Searching for primary malignancy should include HCC as frequent cause of hypercoagulability. In case of HCC, echocardiography is suggested because of the possibility of expansion in MC or right atrium and tumor-embolization.Elod Papp Zsuzsanna Keszthelyi Nagy Karoly Kalmar Lajos Papp Csaba Weninger Tamas Tornoczky Endre Kalman Kalman Toth Tamas Habon 2005World Journal of Gastroenterology2005,11,15:4

15Emblica officinalis improves glycemic status and oxidative stress in STZ induced type 2 diabetic model rats显示文摘Objective:To evaluate the antidiabetic and antioxidant potential of Emblica officinalis(E.officinalis)fruit on normal and type 2 diabetic rats.Methods:Type 2 diabetes was induced into the male Long-Evans rats.The rats were divided into nine groups including control groups receiving water,type 2 diabetic controls,type 2 diabetic rats treated with glibenclamide(T2GT)and type 2diabetic rats treated with aqueous extract of fruit pulp of E.officinalis.They were fed orally for8 weeks with a single feeding.Blood was collected by cutting the tail tip on 0 and 28 days and by decapitation on 56 day.Packed red blood cells and serum were used for evaluating different biochemical parameters.Results:Four weeks administration of aqueous extract of E.officinalis improved oral glucose tolerance in type 2 rats and after 8 weeks it caused significant(P<0.007)reduction in fasting serum glucose level compared to 0 day.Triglycerides decreased by 14%but there was no significant change in serum ALT,creatinine,cholesterol and insulin level in any group.Furthermore,reduced erythrocyte malondialdehyde level showed no significant change(P<0.07)but reduced glutathione content was found to be increased significantly(P<0.05).Conclusions:The aqueous extract of E.officinalis has a promising antidiabetic and antioxidant properties and may be considered for further clinical studies in drug development.Aneesa Ansari Md.Shahed Zaman Shahriar Md.Mehedi Hassan Shukla Rani Das Begum Rokeya Md.Anwarul Haque Md.Enamul Haque Nirupam Biswas Tama Sarkar 2014Asian Pacific Journal of Tropical Medicine2014,7,1:4
16Omics Approaches to Identify PotentialBiomarkers of Inflammatory Diseases in the FocalAdhesion Complex显示文摘Inflammatory diseases such as inflammatory bowel disease(IBD) require recurrent invasive tests, including blood tests, radiology, and endoscopic evaluation both to diagnose and assess disease activity, and to determine optimal therapeutic strategies. Simple ‘bedside' biomarkers could be used in all phases of patient management to avoid unnecessary investigation and guide further management. The focal adhesion complex(FAC) has been implicated in the pathogenesis of multiple inflammatory diseases, including IBD, rheumatoid arthritis, and multiple sclerosis. Utilizing omics technologies has proven to be an efficient approach to identify biomarkers from within the FAC in the field of cancer medicine. Predictive biomarkers are paving the way for the success of precision medicine for cancer patients, but inflammatory diseases have lagged behind in this respect. This review explores the current status of biomarker prediction for inflammatory diseases from within the FAC using omics technologies and highlights the benefits of future potential biomarker identification approaches.Johanne Brooks Alastair Watson Tamas Korcsmaros 2017Genomics, Proteomics & Bioinformatics2017,15,2:4
17Changing human-environment interactions in medium mountains:the Apuseni Mts(Romania)as a case study显示文摘The study of human-environment relationships in mountain areas is important for both theoretical and practical reasons, as many mountain areas suffer similar problems, such as depopulation, unemployment and natural hazards. Medium mountains constitute a special case within mountains, because they are more populated but less attractive as tourist destinations than high mountains. In this context, the Apuseni Mts(Romania) are considered as a case study. In this paper, we apply GIS-based, quantitative methods to characterize the strength and dynamics of human-environment interactions, taking into consideration some environmental factors(elevation, relative height, slope, river distance, lithology, land cover, natural attractions) as well as historical population and recent tourism data. We found that population density has strong(r2>0.8) relationships with all relief factors(elevation, relative height, slope, river distance), and that best-fit functions are nonlinear. We outlined the varying demographic scenarios by elevation zones and interpreted the historically switching sign of population change versus elevation relationship. We demonstrated that lithology also has an impact on the spatial distribution of population, although it is notindependent from the relief effect. The land cover of the mainly cultural landscape is very strongly correlated with relief parameters(especially slope), which suggests good adaptation. We pointed out the dominance of karst objects in the natural tourism potential of the Apuseni Mts and also explored further components of real tourism(spas, heritage, towns). Finally, we concluded that the environmental settings investigated do in fact constrain the spatial framework of society, but socio-economic changes in history can be explained from the side of society, which conforms to the theory of cultural possibilism.TELBISZ Tamas IMECS Zoltan MARl Laszlo BOTTLIK Zsolt 2016Journal of Mountain Science2016,13,9:4
18Abnormalities of uterine cervix in women with inflammatory bowel disease显示文摘AIM: To evaluate the prevalence of abnormalities of the uterine cervix in women with inflammatory bowel disease (IBD) when compared to healthy controls. METHODS: One hundred and sixteen patients with IBD [64 with Crohn’s disease (CD) and 52 with ulcerative colitis (UC)] were matched to 116 healthy controls by age (+/- 2 years) at the time of most recent papanicolaou (Pap) smear. Data collected consisted of age, race, marital status, number of pregnancies, abortions/miscarriages, duration and severity of IBD, Pap smear results within five years of enrollment, and treatment with immunosuppressive drugs. Pap smear results were categorized as normal or abnormal including atypical squamous cells of undetermined significance (ASCUS), low-grade squamous intraepithelial lesion (LGSIL), and high-grade squamous intraepithelial lesion (HGSIL). RESULTS: The median age at the time of Pap smear was 46 (range: 17-74) years for the IBD group and matched controls (range: 19-72 years). There were more Caucasian subjects than other ethnicities in the IBD patient group (P = 0.025), as well as fewer abortions (P = 0.008), but there was no significant difference regarding marital status. Eighteen percent of IBD patients had abnormal Pap smears compared to 5% of controls (P = 0.004). Subgroup analysis of the IBD patients revealed no significant differences between CD and UC patients in age, ethnicity, marital status, number of abortions, disease severity, family history of IBD, or disease duration. No significant difference was observedin the number of abnormal Pap smears or the use of immunosuppressive medications between CD and UC patients (P = 0.793). No definitive observation could be made regarding HPV status, as this was not routinely investigated during the timeframe of our study. CONCLUSION: Diagnosis of IBD in women is related to an increased risk of abnormal Pap smear, while type of IBD and exposure to immunosuppressive medications are not. This has significant implications for women with IBD in that Pap smear screening protocols should be conscientiously followed, with appropriate investigation of abnormal results.Jyoti Bhatia Jason Bratcher Burton Korelitz Katherine Vakher Shlomo Mannor Maria Shevchuk Gworgia Panagopoulos Adam Ofer Ecaterina Tamas Panayota Kotsali Oana Vele 2006World Journal of Gastroenterology2006,12,38:3
