| 1 | Correlation of N-myc downstream-regulated gene 1 expression with clinical outcomes of colorectal cancer patients of different race/ethnicity显示文摘AIM: To evaluate the role of N-myc downstream-regulated gene 1 (NDRG1) expression in prognosis and survival of colorectal cancer patients with different ethnic backgrounds. METHODS: Because NDRG1 is a downstream target of p53 and hypoxia inducible factor-1α (HIF-1α),we examined NDRG1 expression together with p53 and HIF-1α by immunohistochemistry. A total of 157 colorectal cancer specimens including 80 from Japanese patients and 77 from US patients were examined. The correlation between protein expression with clinicopathological features and survival after surgery was analyzed.in colorectal tumor compared with normal epithelium in both Japanese and US patient groups. Expression of NDRG1 protein was significantly correlated with lymphatic invasion,venous invasion,depth of invasion,histopathological type,and Dukes' stage in Japanese colorectal cancer patients. NDRG1 expression was correlated to histopathological type,Dukes' stage and HIF-1α expression in US-Caucasian patients but not in US-African American patients. Interestingly,Kaplan-Meier survival analysis demonstrated that NDRG1 expression correlated significantly with poorer survival in US-African American patients but not in other patient groups. However,in p53-positive US cases,NDRG1 positivity correlated significantly with better survival. In addition,NDRG1 expression also correlated significantly with improved survival in US patients with stages Ⅲ and Ⅳ tumors without chemotherapy. In Japanese patients with stages Ⅱ and Ⅲ tumors,strong NDRG1 staining in p53-positive tumors correlated significantly with improved survival but negatively in patients without chemotherapy. CONCLUSION: NDRG1 expression was correlated with various clinicopathological features and clinical outcomes in colorectal cancer depending on the race/ethnicity of the patients. NDRG1 may serve as a biological basis for the disparity of clinical outcomes of colorectal cancer patients with different ethnic backgrounds. | Minori Koshiji Kensuke Kumamoto Keiichirou Morimura Yasufumi Utsumi Michiko Aizawa Masami Hoshino Shinji Ohki Seiichi Takenoshita Max Costa Thérèse Commes David Piquemal Curtis C Harris Kam-Meng Tchou-Wong | 2007 | World Journal of Gastroenterology2007,13,20: | 25 |

| 5 | Ultrasound-assessed non-culprit and culprit coronary vessels differ by age and gender显示文摘AIM: To investigate age-and gender-related differences in non-culprit versus culprit coronary vessels assessed with virtual histology intravascular ultrasound (VH-IVUS). METHODS: In 390 patients referred for coronary angiography to a single center (Luzerner Kantonsspital, Switzerland) between May 2007 and January 2011, 691 proximal vessel segments in left anterior descending, circumflex and/or right coronary arteries were imaged by VH-IVUS. Plaque burden and plaque composition(fibrous, fibro-fatty, necrotic core and dense calcium volumes) were analyzed in 3 age tertiles, according to gender and separated for vessels containing non-culprit or culprit lesions. To classify as vessel containing a culprit lesion, the patient had to present with an acute coronary syndrome, and the VH-IVUS had to be performed in a vessel segment containing the culprit lesion according to conventional coronary angiography. RESULTS: In non-culprit vessels the plaque burden increased significantly with aging (in men from 37% ± 12% in the lowest to 46% ± 10% in the highest age tertile, P < 0.001; in women from 30% ± 9% to 40% ± 11%, P < 0.001); men had higher plaque burden than women at any age (P < 0.001 for each of the 3 age tertiles). In culprit vessels of the lowest age tertile, plaque burden was significantly higher than that in non- culprit vessels (in men 48% ± 6%, P < 0.001 as compared to non-culprit vessels; in women 44% ± 18%, P = 0.004 as compared to non-culprit vessels). Plaque burden of culprit vessels did not significantly change during aging (plaque burden in men of the highest age tertile 51% ± 9%, P = 0.523 as compared to lowest age tertile; in women of the highest age tertile 49% ± 8%, P = 0.449 as compared to lowest age tertile). In men, plaque morphology of culprit vessels became increasingly rupture-prone during aging (increasing percentages of necrotic core and dense calcium), whereas plaque morphology in non-culprit vessels was less rupture-prone and remained constant during aging. In women, necrotic core in non-culprit vessels was very low at young age, but increased during aging resulting in a plaque morphology that was very similar to men. Plaque morphology in culprit vessels of young women and men was similar. CONCLUSION: This study provides evidence that age-and gender-related differences in plaque burden and plaque composition significantly depend on whether the vessel contained a non-culprit or culprit lesion. | Andreas W Schoenenberger Nadja Urbanek Stefan Toggweiler Andreas E Stuck Thérèse J Resink Paul Erne | 2013 | World Journal of Cardiology2013,5,3: | 7 |

| 7 | Prevalence and virological profiles of hepatitis B infection in human immunodeficiency virus patients显示文摘AIM: To determine the prevalence of hepatitis B virus (HBV) in adult human immunodeficiency virus (HIV) patients with CD4+ T-cell count less than 500/mm 3 and without antiretroviral therapy; to describe different HBV-HIV coinfection virological profiles; and to search for factors associated with HBs antigen (HBsAg) presence in these HIV positive patients.METHODS: During four months (June through September 2006), 491 patients were received in four HIV positive monitoring clinical centers in Abidjan. Inclusion criteria: HIV-1 or HIV-1 and 2 positive patients, age ≥ 18 years, CD4+ T-cell count < 500/mL and formal and signed consent of the patient. Realized blood tests included HIV serology, CD4+ T-cell count, quantitative HIV RNA load and HBV serological markers, such as HBsAg and HBc antibody (anti-HBcAb). We performed HBeAg, anti-HBe antibody (anti-HBeAb), anti-HBc IgM and quantitative HBV DNA load in HBsAg positive patients. Anti-HBsAb had been tested in HIV patients with HBsAg negative and anti-HBcAb-positive. HBV DNA was also tested in 188 anti-HBcAb positive patients with HBsAg negative status and without anti-HBsAb. Univariate analysis (Pearsonχ 2 test or Fischer exact test) and multivariate analysis (backward step-wise selection logistic regression) were performed as statistical analysis. RESULTS: Mean age of 491 patients was 36 ± 8.68 years and 73.3% were female. Type-1 HIV was found in 97% and dual-type HIV (type 1 plus type 2) in 3%. World Health Organization (WHO) clinical stage was 1, 2, 3 and 4 respectively in 61 (12.4%), 233 (47.5%), 172 (35%) and 25 patients (5.1%). Median CD4+ T-cell count was 341/mm 3 (interquartile range: 221-470). One hundred and twelve patients had less than 200 CD4+ T-cell/mm 3 . Plasma HIV-1 RNA load was elevated (≥ 5 log 10 copies/mL) in 221 patients (45%). HBsAg and anti-HBcAb prevalence was respectively 13.4% and 72.9%. Of the 66 HBsAg positive patients, 22 were inactive HBV carriers (33.3%), 21 had HBeAg positive hepatitis (31.8%) and 20 had HBeAg negative hepatitis (30.3%). HBeAg and anti-HBeAb were indeterminate in 3 of them. Occult B infection prevalence (HBsAg negative, anti-HBcAb positive, anti-HBsAb negative and detectable HBV DNA) was 21.3%. Three parameters were significantly associated with the presence of HBsAg: male [odds ratio (OR): 2.2;P = 0.005; 95% confidence interval (CI): 1.3-3.8]; WHO stage 4 (OR: 3.2;P = 0.01;95% CI: 1.3-7.9); and aspartate aminotransferase (AST) level higher than the standard (OR: 1.9;P = 0.04; 95% CI: 1.02-3.8). CONCLUSION: HBV infection prevalence is high in HIV-positive patients. HBeAg positive chronic hepatitis and occult HBV infection are more frequent in HIVpositive patients than in HIV negative ones. Parameters associated with HBsAg positivity were male gender, AIDS status and increased AST level. | Koffi Alain Attia Serge Eholié Eugène Messou Christine Danel Sandrine Polneau Henri Chenal Thomas Toni Myreille Mbamy Catherine Seyler Naomi Wakasugi Thérèse N'dri-Yoman Xavier Anglaret | 2012 | World Journal of Hepatology2012,4,7: | 4 |
| 8 | Hepatitis C virus genotypes distribution and transmission risk factors in Luxembourg from 1991 to 2006显示文摘AIM:To analyze the Hepatitis C virus (HCV) genotype distribution and transmission risk factors in a population of unselected patients in Luxembourg. METHODS:Epidemiological information (gender, age and transmission risks) were collected from 802 patients newly diagnosed for hepatitis C and living in Luxembourg, among whom 228 patients referred from prison. Genotyping using 5'noncoding (5'NC) sequencing was performed. We compared categorical data using the Fisher's exact F-test and odds ratios (OR) were calculated for evaluating association of HCV genotype and risk factors. RESULTS:The sex ratio was predominantly male (2.2) and individuals aged less than 40 years represented 49.6% of the population. Genotype 1 was predominant (53.4%) followed by genotype 3 (33%). Among risk factors, intravenous drug usage (IVDU) was the most frequently reported (71.4%) followed by medical-related transmission (17.6%) including haemophilia, transfusion recipients and other nosocomial reasons. Genotype 3 was significantly associated to IVDU (OR = 4.84, P < 0.0001) whereas genotype 1 was significantly associated with a medical procedure (OR = 2.42, P < 0.001). The HCV genotype distribution from inmate patients differed significantly from the rest of the population (Chi-square test with four degrees of freedom, P < 0.0001) with a higher frequency of genotype 3 (46.5% vs 27.5%) and a lower frequency of genotype 1 and 4 (44.7% vs 56.8% and 5.3% vs 9.6%, respectively). IVDU was nearly exclusively reported as a risk factor in prison. CONCLUSION:We report the first description of the HCV genotype distribution in Luxembourg. The repartition is similar to other European countries, with one of the highest European prevalence rates of genotype 3 (33%). Since serology screening became available in 1991, IVDU remains the most common way of HCV transmission in Luxembourg. | Francois Roman Karin Hawotte Daniel Struck Anne-Marie Ternes Jean-Yves Servais Vic Arendt Patrick Hoffman Robert Hemmer Thérèse Staub Carole Seguin-Devaux Jean-Claude Schmit | 2008 | World Journal of Gastroenterology2008,14,8: | 3 |

| 10 | Deoxynivalenol accumulation and detoxification in cereals and its potential role in wheat-Fusarium graminearum interactions显示文摘Deoxynivalenol(DON)is a prominent mycotoxin showing significant accumulation in cereal plants during infection by the phytopathogen Fusarium graminearum.It is a virulence factor that is important in the spread of F.graminearum within cereal heads,and it causes serious yield losses and significant contamination of cereal grains.In recent decades,genetic and genomic studies have facilitated the characterization of the molecular pathways of DON biosynthesis in F.graminearum and the environmental factors that influence DON accumulation.In addition,diverse scab resistance traits related to the repression of DON accumulation in plants have been identified,and experimental studies of wheat–pathogen interactions have contributed to understanding detoxification mechanisms in host plants.The present review illustrates and summarizes the molecular networks of DON mycotoxin production in F.graminearum and the methods of DON detoxification in plants based on the current literature,which provides molecular targets for crop improvement programs.This review also comprehensively discusses recent advances and challenges related to genetic engineering-mediated cultivar improvements to strengthen scab resistance.Furthermore,ongoing advancements in genetic engineering will enable the application of these molecular targets to develop more scab-resistant wheat cultivars with DON detoxification traits. | Kun Luo Jiao Guo Dejia He Guangwei Li Thérèse Ouellet | 2023 | aBIOTECH2023,4,2: | 2 |

| 12 | 治疗选择偏倚的存在与观察性研究分析:使用倾向积分法和工具变量法评价心脏介入治疗对AMI存活的影响显示文摘背景:对观察性研究中治疗与未治疗患者的结果进行比较时,由于患者预后存在组间差异,因此可发生偏倚,后者常常是因为存在未予观察的治疗选择偏倚。
目的:对下列4种去除观察性研究选择偏倚的分析方法进行比较:多变量模型危险校正法(muhivariable model risk adjustment)、倾向积分危险校正法(propensity score risk adjustment)、倾向匹配法(propensity—based matching)以及工具变量分析法(instrumental variable analysis)。
设计、地点及患者:122124例因急性心肌梗死(AMI)而于1994~1995年住院的、接受医疗保险的老年(年龄65~84岁)患者全国队列。这些患者适合心脏导管检查。基线图表审查取自心血管协作项目并与医疗保险健康管理数据联合以便提供系列预后变量。患者随访7年(至2001年12月31日)以便评估长期存活与住院30天内心脏导管检查两者的关系。
主要观测指标:使用各种分析方法获得的危险校正后相对死亡率。
结果:与未接受心导管检查的患者相比,接受心导管检检查的患者较年轻而且急性心肌梗死的严重度较低。采用标准的统计学危险校正法校正预后因素后,心导管检查与死亡率相对下降50%相关(多变量模型危险矫正法:校正后相对危险度[relative risk,RR],〉0.51;95%可信区间[confidence interval,CI],0.50~0.52。倾向积分危险校正法:校正后RR,0.54;95%CI,0.53~0.55]。倾向配对法:校正后RR,0.54;95%CI,0.52~0.56)。使用局部插管作为一种工具,工具变量分析显示死亡率相对下降16%(校正后RR,0.84;95%CI,0.79~0.90)。随机临床试验中常规介入治疗的生存获益在8%和21%之间。
结论:心导管检查与急性心肌梗死长期死亡率的关系对分析方法高度敏感。对于去除未测量的治疗选择偏倚而言,各种标准危险校正方法具有同样的局限。与标准建模法比较,工具变量分析法可以减少治疗效果偏倚。但是相对于特殊的临床问题,该法更适合回答政策策略问题。 | Thérèse A. Stukel Elliott S. Fisher David E. Wennberg 李呈亿(译) | 2007 | 美国医学会杂志(中文版)2007,26,6: | 2 |
