1核磁共振法表征硫黄用量对天然橡胶交联密度及结构的影响显示文摘用核磁共振(NMR)法测定了硫黄用量及硫化温度对天然橡胶(NR)硫化胶交联结构的影响,并与传统的平衡溶胀法进行了对比。结果表明,用NMR法可以测定硫化胶的总交联密度、未硫化胶的物理交联密度和由于交联反应产生的化学交联密度;NR硫化胶的总交联密度和化学交联密度随硫黄用量的增加而呈线性增加;随着硫黄用量的增加,交联密度增加,NR硫化胶的纵向弛豫时间和横向弛豫时间下降;NR硫化胶的交联密度越大,弛豫时间对温度的依赖性越小;NMR法可以清晰展示NR/硫黄/促进剂NS硫化体系的硫化过程中橡胶交联点间的相对分子质量、化学交联密度及橡胶大分子连到橡胶交联网络上的演变过程。赵菲 张萍 赵树高 Winfried Kuhn 于建 2008合成橡胶工业2008,31,2:38
2用核磁共振法研究促进剂对硫黄硫化天然橡胶结构的影响显示文摘用核磁共振交联密度仪研究了次磺酰胺类促进剂NS、DZ和CZ对天然橡胶硫化胶结构的影响,考察了相同用量下促进剂种类与天然橡胶硫化胶交联密度的关系。结果表明,在基本配方和硫化条件相同的情况下,促进剂的相对分子质量越低,天然橡胶硫化胶的交联密度越高。硫化胶的交联密度不仅对核磁共振的横向弛豫时间有影响,而且影响其纵向弛豫时间。随着交联密度的增加,硫化胶的核磁共振弛豫时间缩短,弛豫时间对温度的依赖性减弱。赵菲 毕薇娜 张萍 于建 Winfried Kuhn 2008合成橡胶工业2008,31,1:33

6Psychosocial issues in evidence-based guidelines on inflammatory bowel diseases: A review显示文摘AIM:To study statements and recommendations on psychosocial issues as presented in international evidence-based guidelines on the management of inflammatory bowel diseases(IBD).METHODS:MEDLINE,guidelines International Network,National Guideline Clearing House and National Institute for Health and Care Excellence were searched from January 2006 to June 30,2013 for evidencebased guidelines on the management of IBD.RESULTS:The search yielded 364 hits.Thirteen guidelines were included in the review,of which three wereprepared in Asia,eight in Europe and two in the United States.Eleven guidelines made statements and recommendations on psychosocial issues.The guidelines were concordant in that mental health disorders and stress do not contribute to the aetiology of IBD,but that they can influence its course.It was recommended that IBD-patients should be screened for psychological distress.If indicated,psychotherapy and/or psychopharmacological therapy should be recommended.IBDcentres should collaborate with mental health care specialists.Tobacco smoking patients with Crohn’s disease should be advised to quit.CONCLUSION:Patients and mental health specialists should be able to participate in future guideline groups to contribute to establishing recommendations on psychosocial issues in IBD.Future guidelines should acknowledge the presence of psychosocial problems in IBD-patients and encourage screening for psychological distress.Winfried Huser Gabriele Moser Petra Klose Antonina Mikocka-Walus 2014World Journal of Gastroenterology2014,20,13:14

12Association of the GNAS1 T393C polymorphism with tumor stage and survival in gastric cancer显示文摘AIM:To analyze the impact of the GNAS1 T393C polymorphism on prognosis and histopathology of gastric cancer.METHODS:Genomic DNA was extracted from paraffinembedded tissues of 122 patients with primary gastric carcinoma and from the blood of 820 healthy white individuals.Allelic discrimination was performed by quantitative real-time polymerase chain reaction.Genotyping was correlated with histopathologic parameters and with overall survival according to the Kaplan-Meier approach and with multivariate analysis by multiple stepwise regression.RESULTS:Thirty-nine(32%) patients displayed a CC genotype,57(46.7%) a CT genotype and 26(21.3%) a TT genotype.The frequency of the C allele(fC) in the patient group was 0.55,which was not signif icantly different from that of healthy blood donors.The distribution was compatible with the Hardy-Weinberg equilibrium.Analysis of clinicopathological parameters did not show any signif icant correlation of the T393C genotype with gender(P=0.50),differentiation(P=0.29),pT-category(P=0.19),pN-category(P=0.30),pM-category(P=0.25),R-category(P=0.95),the classifications according to WHO(P=0.34),Laurén(P=0.16),Goseki(P=1.00) and Ming(P=0.74).Dichotomization between C+(CC+CT) and C-genotypes(TT),however,revealed signif icantly more advanced tumor stages(P=0.023) and lower survival rates(P=0.043) for C allele carriers.CONCLUSION:The present study provides strong evidence to suggest that the GNAS1 T393C allele carrier status influences tumor progression and survival in gastric cancer with higher tumor stages and a worse outcome for C allele carriers.Hakan Alakus Stefan P Mnig Ute Warnecke-Eberz Gül Alakus Günther Winde Uta Drebber Klaus J Schmitz Kurt W Schmid Kathrin Riemann Winfried Siffert Elfriede Bollschweiler Arnulf H Hlscher Ralf Metzger 2009World Journal of Gastroenterology2009,15,48:3

14Hydroxyethylstarch revisited for acute brain injury treatment显示文摘Infusion of the colloid hydroxyethylstarch has been used for volume substitution to maintain hemodynamics and microcirculation after e.g., severe blood loss.In the last decade it was revealed that hydroxyethylstarch can aggravate acute kidney injury, especially in septic patients.Because of the serious risk for critically ill patients, the administration of hydroxyethylstarch was restricted for clinical use.Animal studies and recently published in vitro experiments showed that hydroxyethylstarch might exert protective effects on the blood-brain barrier.Since the prevention of blood-brain barrier disruption was shown to go along with the reduction of brain damage after several kinds of insults, we revisit the topic hydroxyethylstarch and discuss a possible niche for the application of hydroxyethylstarch in acute brain injury treatment.Martin A.Schick Malgorzata Burek Carola Y.Forster Michiaki Nagai Christian Wunder Winfried Neuhaus 2021Neural Regeneration Research2021,16,7:2

20Microbiological screenings for infection control in unaccompanied minor refugees: the German Armed Forces Medical Service's experience显示文摘Background:The German Military Medical Service contributed to the medical screening of unaccompanied minor refugees(UMRs)coming to Germany in 2014 and 2015.In this study,a broad range of diagnostic procedures was applied to identify microorganisms with clinical or public health significance.Previously,those tests had only been used to screen soldiers returning from tropical deployments.This instance is the first time the approach has been studied in a humanitarian context.Methods:The offered screenings included blood cell counts,hepatitis B serology and microscopy of the stool to look for protozoa and worm eggs as well as PCR from stool samples targeting pathogenic bacteria,protozoa and helminths.If individuals refused certain assessments,their decision to do so was accepted.A total of 219 apparently healthy male UMRs coming from Afghanistan,Egypt,Somalia,Eritrea,Syria,Ghana,Guinea,Iran,Algeria,Iraq,Benin,Gambia,Libya,Morocco,Pakistan,and Palestine were assessed.All UMRs who were examined at the study department were included in the assessment.Results:We detected decreasing frequencies of pathogens that included diarrhoea-associated bacteria[Campylobacter(C.)jejuni,enteropathogenic Escherichia(E.)coli(EPEC),enterotoxic E.coli(ETEC),enteroaggregative E.coli(EAEC),enteroinvasive E.coli(EIEC)/Shigella spp.),Giardia(G.)duodenalis,helminths(comprising Schistosoma spp.,Hymenolepis(H.)nana,Strongyloides(S.)stercoralis]as well as hepatitis B virus.Pathogenic microorganisms dominated the samples by far.While G.duodenalis was detected in 11.4%of the assessed UMRs,the incidence of newly identified cases in the German population was 4.5 cases per 100,000 inhabitants.Conclusion:We conclude that the applied in-house PCR screening systems,which have proven to be useful for screening military returnees from tropical deployments,can also be used for health assessment of immigrants from the respective sites.Apparently healthy UMRs may be enterically colonized with a broad variety of pathogenic and apathogenic microorganisms.Increased colonization rates,as shown for G.duodenalis,can pose a hygiene problem in centralized homes for asylum seekers.Winfried Maaβen Dorothea Wiemer Claudia Frey Christina Kreuzberg Egbert Tannich Rebecca Hinz Andreas Wille Andreas Fritsch Ralf Matthias Hagen Hagen Frickmann 2018Military Medical Research2018,5,1:2
