| 1 | 生物质燃烧颗粒物有机示踪化合物的测定和应用显示文摘使用气相色谱-质谱法对2002年7月-2003年7月的北京市大气粗、细颗粒物样品中的左旋葡聚糖等糖类化合物进行了测定。结果表明,左旋葡聚糖主要存在于细颗粒中,可以作为示踪化合物来研究生物质燃烧现象。生物质燃烧对北京市大气颗粒物有较重要的贡献,对应于12%-40%的PM2.5有机碳和10%-33%的PM10有机碳。北京市在2002年10月和11月受到明显的生物质燃烧的影响,可能由于农田秸杆焚烧和秋季落叶焚烧。2003年5月7日颗粒物样品受到直线距离约为1000 km以外的内蒙古自治区呼伦贝尔市大兴安岭林区森林大火烟雾的影响。生物质燃烧事件具有突发性,可以长距离传输;生物质作为农村生物燃料的使用其燃烧排放具有经常性和持久性的特征。 | 张烃 刘咸德 董树屏 祁辉 Hélène Cachier Magda Claeys | 2006 | 岩矿测试2006，25，2： | 17 |
| 2 | Occult hepatitis B virus infection among Egyptian blood donors显示文摘AIM:To identify blood donors with occult hepatitis B virus(HBV) infection(OBI) to promote safe blood donation.METHODS:Descriptive cross sectional study was conducted on 3167 blood donors negative for hepatitis B surface antigen(HBsAg),hepatitis C antibody(HCV Ab) and human immunodeficiency virus Ab.They were subjected to the detection of alanine aminotransferase(ALT) and aspartate transaminase(AST) and screening for anti-HBV core antibodies(total) by two different techniques;[Monoliza antibodies to hepatitis B core(Anti-HBc) Plus-Bio-Rad] and(ARC-HBc total-ABBOT).Positive samples were subjected to quantitative detection of antibodies to hepatitis B surface(anti-HBs)(ETI-AB-AUK-3,Dia Sorin-Italy).Serum anti-HBs titers > 10 IU/L was considered positive.Quantitative HBV DNA by real time polymerase chain reaction(PCR)(QIAGEN-Germany) with 3.8 IU/mL detection limit was estimated for blood units with negative serum anti-HBs and also for 32 whose anti-HBs serum titers were > 1000 IU/L.Also,265 recipients were included,34 of whom were followed up for 3-6 mo.Recipients were investigated for ALT and AST,HBV serological markers:HBsAg(ETI-MAK-4,Dia Sorin-Italy),anti-HBc,quantitative detection of anti-HBs and HBV-DNA.RESULTS:525/3167(16.6%) of blood units were positive for total anti-HBc,64% of those were antiHBs positive.Confirmation by ARCHITECT anti-HBc assay were carried out for 498/525 anti-HBc positive samples,where 451(90.6%) confirmed positive.Reactivity for anti-HBc was considered confirmed only if two positive results were obtained for each sample,giving an overall prevalence of 451/3167(14.2%) for total anti-HBc.HBV DNA was quantified by real time PCR in 52/303(17.2%) of anti-HBc positive blood donors(viral load range:5 to 3.5 x 105 IU/mL) with a median of 200 IU/mL(mean:1.8 x 104 ± 5.1 x 104 IU/mL).AntiHBc was the only marker in 68.6% of donors.Univariate and multivariate logistic analysis for identifying risk factors associated with anti-HBc and HBV-DNA positivity among blood donors showed that age above thirty and marriage were the most significant risk factors for prediction of anti-HBc positivity with AOR 1.8(1.4-2.4) and 1.4(1.0-1.9) respectively.Other risk factors as gender,history of blood transfusion,diabetes mellitus,frequent injections,tattooing,previous surgery,hospitalization,Bilharziasis or positive family history of HBV or HCV infections were not found to be associated with positive anti-HBc antibodies.Among anti-HBc positive blood donors,age below thirty was the most significant risk factor for prediction of HBV-DNA positivity with AOR 3.8(1.8-7.9).According to HBV-DNA concentration,positive samples were divided in two groups;group one with HBV-DNA ≥ 200 IU/mL(n = 27) and group two with HBV-DNA < 200 IU/mL(n = 26).No significant difference was detected between both groups as regards mean age,gender,liver enzymes or HBV markers.Serological profiles of all followed up blood recipients showed that,all were negative for the studied HBV markers.Also,HBV DNA was not detected among studied recipients,none developed post-transfusion hepatitis(PTH) and the clinical outcome was good.CONCLUSION:OBI is prevalent among blood donors.Nucleic acid amplification/HBV anti core screening should be considered for high risk recipients to eliminate risk of unsafe blood donation. | Zeinab N Said Manal H El Sayed Iman I Salama Enas K Aboel-Magd Magda H Mahmoud Maged El Setouhy Faten Mouftah Manal B Azzab Heidi Goubran Amal Bassili Gamal E Esmat | 2013 | World Journal of Hepatology2013，5，2： | 4 |
| 3 | Prediction of delayed graft function using different scoring algorithms: A single-center experience显示文摘AIM To compare the performance of 3 published delayed graftfunction(DGF) calculators that compute the theoretical risk of DGF for each patient.METHODS This single-center,retrospective study included 247 consecutive kidney transplants from a deceased donor.These kidney transplantations were performed at our institution between January 2003 and December 2012.We compared the occurrence of observed DGF in our cohort with the predicted DGF according to three different published calculators. The accuracy of the calculators was evaluated by means of the c-index(receiver operating characteristic curve).RESULTS DGF occurred in 15.3% of the transplants under study.The c index of the Irish calculator provided an area under the curve(AUC) of 0.69 indicating an acceptable level of prediction,in contrast to the poor performance of the Jeldres nomogram(AUC = 0.54) and the Chapal nomogram(AUC = 0.51). With the Irish algorithm the predicted DGF risk and the observed DGF probabilities were close. The mean calculated DGF risk was significantly different between DGF-positive and DGF-negative subjects(P < 0.0001). However,at the level of the individual patient the calculated risk of DGF overlapped very widely with ranges from 10% to 51% for recipients with DGF and from 4% to 56% for those without DGF.The sensitivity,specificity and positive predictive value of a calculated DGF risk ≥ 30% with the Irish nomogram were 32%,91% and 38%. CONCLUSION Predictive models for DGF after kidney transplantation are performant in the population in which they were derived,but less so in external validations. | Magda Michalak Kristien Wouters Erik Fransen Rachel Hellemans Amaryllis H Van Craenenbroeck Marie M Couttenye Bart Bracke Dirk K Ysebaert Vera Hartman Kathleen De Greef Thiery Chapelle Geert Roeyen Gerda Van Beeumen Marie-Paule Emonds Daniel Abramowicz Jean-Louis Bosmans | 2017 | World Journal of Transplantation2017，7，5： | 3 |
