| 2 | Bone Regeneration Based on Tissue Engineering Conceptions – A 21st Century Perspective显示文摘The role of Bone Tissue Engineering in the field of Regenerative Medicine has been the topic of substantial research over the past two decades.Technological advances have improved orthopaedic implants and surgical techniques for bone reconstruction.However,improvements in surgical techniques to reconstruct bone have been limited by the paucity of autologous materials available and donor site morbidity.Recent advances in the development of biomaterials have provided attractive alternatives to bone grafting expanding the surgical options for restoring the form and function of injured bone.Specifically,novel bioactive(second generation)biomaterials have been developed that are characterised by controlled action and reaction to the host tissue environment,whilst exhibiting controlled chemical breakdown and resorption with an ultimate replacement by regenerating tissue.Future generations of biomaterials(third generation)are designed to be not only osteoconductive but also osteoinductive,i.e.to stimulate regeneration of host tissues by combining tissue engineering and in situ tissue regeneration methods with a focus on novel applications.These techniques will lead to novel possibilities for tissue regeneration and repair.At present,tissue engineered constructs that may find future use as bone grafts for complex skeletal defects,whether from post-traumatic,degenerative,neoplastic or congenital/developmental'origin'require osseous reconstruction to ensure structural and functional integrity.Engineering functional bone using combinations of cells,scaffolds and bioactive factors is a promising strategy and a particular feature for future development in the area of hybrid materials which are able to exhibit suitable biomimetic and mechanical properties.This review will discuss the state of the art in this field and what we can expect from future generations of bone regeneration concepts. | Jan Henkel Maria A.Woodruff Devakara R.Epari Roland Steck Vaida Glatt Ian C.Dickinson Peter F.M.Choong Michael A.Schuetz Dietmar W.Hutmacher | 2013 | Bone Research2013,1,3: | 33 |
| 3 | Distinct gut microbiota profiles in patients with primary sclerosing cholangitis and ulcerative colitis显示文摘AIM To characterize the gut bacterial microbiota of patients with primary sclerosing cholangitis(PSC) and ulcerative colitis(UC).METHODS Stool samples were collected and relevant clinical data obtained from 106 study participants, 43 PSC patients with(n = 32) or without(n = 11) concomitant inflammatory bowel disease, 32 UC patients, and 31 healthy controls. The V3 and V4 regions of the 16 S ribosomal RNA gene were sequenced on Illumina Mi Seq platform to cover low taxonomic levels. Data were further processed in QIIME employing Ma As Lin and LEf Se tools for analysis of the output data.RESULTS Microbial profiles in both PSC and UC were characterized by low bacterial diversity and significant change in global microbial composition. Rothia, Enterococcus, Streptococcus, Veillonella, and three other genera were markedly overrepresented in PSC regardless of concomitant inflammatory bowel disease(IBD). Rothia, Veillonella and Streptococcus were tracked to the species level to identify Rothia mucilaginosa, Streptococcus infantus, S. alactolyticus, and S. equi along with Veillonella parvula and V. dispar. PSC was further characterized by decreased abundance of Adlercreutzia equolifaciens and Prevotella copri. Decrease in genus Phascolarctobacterium was linked to presence of colonic inflammation regardless of IBD phenotype. Akkermansia muciniphila, Butyricicoccus pullicaecorum and Clostridium colinum were decreased in UC along with genus Roseburia. Low levels of serum albumin were significantly correlated with enrichment of order Actinomycetales.CONCLUSION PSC is associated with specific gut microbes independently of concomitant IBD and several bacterial taxa clearly distinguish IBD phenotypes(PSC-IBD and UC). | Lukas Bajer Miloslav Kverka Martin Kostovcik Peter Macinga Jiri Dvorak Zuzana Stehlikova Jan Brezina Pavel Wohl Julius Spicak Pavel Drastich | 2017 | World Journal of Gastroenterology2017,23,25: | 22 |

| 6 | Sirolimus inhibits growth of human hepatoma cells alone or combined with tacrolimus, while tacrolimus promotes cell growth显示文摘AIM: Standard immunosuppression after organ transplantation stimulates tumor growth. Sirolimus has a strong antiproliferative and a tumor inhibiting effect. The purpose is to assess the effect on tumor growth of the immunosuppressive compounds sirolimus and tacrolimus alone and in combination on cells of human hepatocellular carcinoma.METHODS: We used the human cell lines SK-Hep 1 and Hep 3B derived from hepatocellular carcinoma. Proliferation analyses after treatment with sirolimus, tacrolimus, or the combination of both were performed. FACS analyses were done to reveal cell cycle changes and apoptotic cell death. The expression of apoptosis-related proteins was estimated by Western blots.RESULTS: Sirolimus alone or combined with tacrolimus inhibited the growth of both cell lines after 5 d by up to 35% in SK-Hep 1 cells, and by up to 68% in Hep 3B cells at 25 ng/mL. Tacrolimus alone stimulated the growth by 12% after 5 ng/mL and by 25% after 25 ng/mL in Hep 3B cells. We found an increase of apoptotic Hep 3B cells from 6 to 16%, and a G1-arrest in SK-Hep 1 cells with an increase of cells from 61 to 82%, when sirolimus and tacrolimus were combined. Bcl-2 was down-regulated in Hep 3B, but not in SK-Hep 1 cells after combined treatment.CONCLUSION: Sirolimus appears to inhibit the growth of hepatocellular carcinoma cells alone and in combination with tacrolimus. Sirolimus seems to inhibit the growth stimulation of tacrolimus. | Guido Schumacher Marijke Oidtmann Anne Rueggeberg Dietmar Jacob Sven Jonas Jan M.

| 9 | Cyclooxygenase-2 polymorphisms and the risk of esophageal adeno-or squamous cell carcinoma显示文摘AIM:To determine whether-1195 A→G and/or-765 G→C polymorphisms in Cyclooxygenase-2(COX-2 ) may have a risk modifying effect on the development of esophageal carcinoma in a Dutch Caucasian population.METHODS:Two study groups were recruited, 252 patients with esophageal carcinoma and 240 healthy controls, matched for race, age, gender and recruiting area.DNA was isolated from whole blood and used for genotyping.PCR products were digested with restriction enzymes and products were analyzed by agarose gel electrophoresis.Odds ratios(OR) and 95% confldence intervals(CI) were estimated.RESULTS:The distribution of the-1195 A→G polymorphism was signif icantly different in esophageal cancer patients compared to controls.The-1195 GG genotype resulted in a higher risk of developing esophageal adenocarcinoma(OR = 3.85, 95% CI:1.45-10.3) compared with the-1195 AA genotype as a reference.The-765 G→C genotype distribution was not different between the two groups.The GG/ GG haplotype was present more often in esophageal adenocarcinoma patients than in controls(OR = 3.45, 95% CI:1.24-9.58;with AG/AG as a reference).The same trends were observed in patients with squamous cell carcinomas, however, the results did not reach statistical signif icance.CONCLUSION:Presence of the COX-2-1195 GG genotype and of the GG/GG haplotype may result in a higher risk of developing esophageal carcinoma. | Jón O Kristinsson Paul van Westerveld Rene HM te Morsche Hennie MJ Roelofs T Wobbes Ben JM Witteman Adriaan CITL Tan Martijn GH van Oijen Jan BMJ Jansen Wilbert HM Peters | 2009 | World Journal of Gastroenterology2009,15,28: | 11 |
| 10 | Different antibiotic susceptibility between antrum and corpus of the stomach,a possible reason for treatment failure of Helicobacter pylori infection显示文摘AIM:To assess whether antibiotic resistance varies between the antrum and corpus of the stomach of patients that are either Helicobacter pylori(H.pylori)therapy-naive or pre-treated.METHODS:H.pylori strains were isolated from antrum and corpus biopsies from 66 patients that received a diagnostic gastroduodenoscopy for variant clinical indications.Antimicrobial susceptibility to amoxicillin,clarithromycin,tetracycline,metronidazole,levofloxacin and rifabutin was tested with the E-test method on IsoSensitest agar with 10 vol%defibrinated horse blood.In patients with a different antibiotic susceptibility pattern between the isolates from the antrum and corpus,DNA fingerprinting via random amplified polymorphic DNA analysis was performed to detect differences among DNA patterns of H.pylori isolates.RESULTS:Primary,secondary and tertiary resistance to clarithromycin was 6.9%,53.8%and 83.3%,retrospectively.Metronidazole and levofloxacin resistance also increased according to the number of previous treatments(17.2%,69.2%,83.3%;13.8%,23.1%,33.3%).Tertiary resistance to rifabutin was detected in12.5%of patients.In none of the 66 patients a resistance against amoxicillin or tetracycline was detectable.Discordant antibiotic susceptibility between antrum and corpus isolates for different antibiotics was seen in 15.2%(10/66)of the patients.Two out of those ten patients were naive to any H.pylori antibiotic treatment.The remaining eight patients previously received at least one eradication therapy.DNA fingerprinting analysis revealed no substantial differences among DNA patterns between antrum and corpus isolates in the majority of patients suggesting an infection with a single H.pylori strain.CONCLUSION:Different antibiotic susceptibility between antrum and corpus biopsies is a common phenomenon and a possible explanation for treatment failure.Resistant H.pylori strains may be missed if just one biopsy from one anatomic site of the stomach is taken for H.pylori susceptibility testing. | Michael Selgrad Ina Tammer Cosima Langner Jan Bornschein Julia Mei?le Arne Kandulski Mariya Varbanova Thomas Wex Dirk Schlüter Peter Malfertheiner | 2014 | World Journal of Gastroenterology2014,20,43: | 10 |

| 13 | 基于TerraSAR-X强度图像相关法测量三峡树坪滑坡时空形变显示文摘三峡工程蓄水之后,有可能引起两岸滑坡的发生。本文以三峡库区树坪为研究区域,对不同时相的TerraSAR-X的强度图进行相关计算,求解出2009年2月至2009年10月期间发生的滑坡位移场时空演化。结果表明,在滑坡发生的前几个月,累积变形量很小;在滑坡发生的两三个月当中,变形量比较大,平均位移达到51cm;之后的几个月中,变形量又恢复到平静期的数值,与布设在该区的位移伸缩计结果一致。从本文的研究可以看出,该方法不仅能计算出滑坡引起的形变场,而且能探测地面形变的早期信号,可以用它作为三峡库区未来滑坡监测的重要技术手段。 | 李小凡 MULLER Jan Peter 方晨 赵永红 | 2011 | 岩石学报2011,27,12: | 8 |
| 14 | 正常人额面QRS电轴的年龄趋势以及对肢体导联QRS波振幅的影响显示文摘目的调查和评估正常人额面QRS电轴的年龄趋势以及对肢体导联QRS波振幅的影响。方法采集5360例(男性3614例、女性1746例,年龄范围18~84岁)正常健康人12导联心电图分为5个年龄组,计算和分析各年龄组额面QRS电轴的中位数以及肢体导联QRS波振幅的中位数和96%的正常范围上、下限。结果随年龄增长,男、女额面QRS中位数电轴一致性地逐渐向左(上)偏移大约27°(从70°偏移到43°,P<0.001)。Ⅰ和aVL导联的R波振幅随年龄增长显著增加(P<0.001),而下壁导联Ⅱ、Ⅲ和aVF的R波振幅随年龄增长显著降低(P>0.001)。肢体导联R波振幅随年龄的变化趋势与额面QRS电轴的年龄趋势相一致。结论正常人额面QRS电轴随年龄增长逐渐向左(上)偏移,呈现明确的年龄趋势。QRS电轴的生理性演变可引起肢体导联QRS波振幅呈现明显的年龄差异。显然,把一个相同的左心室肥大心电图诊断标准应用到不同年龄组人群是不合适的。 | 吴杰 Jan A Kors Peter R Rijnbeek Gerard van Herpen 徐春芳 陆再英 | 2006 | 中华心律失常学杂志2006,10,3: | 8 |
| 15 | Association between hepatitis B and metabolic syndrome:Current state of the art显示文摘Chronic hepatitis B(CHB)is a global health issue that increases the risk of liver cirrhosis and hepatocellular carcinoma in infected patients.Metabolic syndrome(Met S)is a disease endemic mostly to the developed countries.It is associated with high cardiovascular mortality and morbidity,diabetes mellitus as well as cancer.In this manuscript,we systematically review the published data on the relationship between Met S and CHB infection.Multiple studies have described highly variable correlations between CHB on one hand and Met S,non-alcoholic fatty liver disease and dyslipidemia on the other.No association between CHB and diabetes mellitus or atherosclerosis has been described as of now.The presence of Met S in patients infected with hepatitis B virus increases the risk of fibrosis,cirrhosis and hepatocellular carcinoma.Appropriate lifestyle,but also pharmacological interventions are needed to prevent the development of these complications. | Peter Jarcuska Sylvia Drazilova Jan Fedacko Daniel Pella Martin Janicko | 2016 | World Journal of Gastroenterology2016,22,1: | 8 |
| 16 | Clinical trial perspective for adult and juvenile Huntington's disease using genetically-engineered mesenchymal stem cells显示文摘Progress to date from our group and others indicate that using genetically-engineered mesenchymal stem cells(MSC) to secrete brain-derived neurotrophic factor(BDNF) supports our plan to submit an Investigational New Drug application to the Food and Drug Administration for the future planned Phase 1 safety and tolerability trial of MSC/BDNF in patients with Huntington's disease(HD). There are also potential applications of this approach beyond HD. Our biological delivery system for BDNF sets the precedent for adult stem cell therapy in the brain and could potentially be modified for other neurodegenerative disorders such as amyotrophic lateral sclerosis(ALS), spinocerebellar ataxia(SCA), Alzheimer's disease, and some forms of Parkinson's disease. The MSC/BDNF product could also be considered for studies of regeneration in traumatic brain injury, spinal cord and peripheral nerve injury. This work also provides a platform for our future gene editing studies, since we will again use MSCs to deliver the needed molecules into the central nervous system. | Peter Deng Audrey Torrest Kari Pollock Heather Dahlenburg Geralyn Annett Jan A.Nolta Kyle D.Fink | 2016 | Neural Regeneration Research2016,11,5: | 7 |
| 17 | 成人健康人群心电图正常范围的调查显示文摘目的调查和评估我国成人健康人群心电图的正常范围。方法采集5360例(男性3614例,女性1746例,年龄范围18~84岁)健康人12导联同步心电图并按性别分为5个年龄组,计算和分析男、女各年龄组心电图参数的中位数及96%范围的正常上、下限,并比较其年龄和性别差异。结果PR间期、QTc间期、额面QRS电轴呈现明确的年龄趋势(P〈0.001)。PR间期、QRS波时限、QTc间期及不同导联QRS波和T波振幅存在明显的性别差异(P〈0.001)。男性PR间期上限值约为200ms,女性PR间期上限值从180ms随年龄增长逐渐增加到200ms。男性QRS波时限上限值为120ms,女性为109ms。各年龄组男、女性QTc间期上限值均〉440ms,女性QTc间期〉440ms的发生率(12.8%)明显高于男性(6.2%)。男性QRS电轴的正常范围为-37°~+94°,女性为-27°~+91°.Q波时限正常范围有明确的导联依赖性。在胸前导联,男性T波幅度的正常值不超过1.44mV,女性不超过0.9mV;在肢体导联,男性不超过0.54mV,女性不超过0.45mV。值得注意的是,肢体导联QRS振幅随年龄增长的变化规律与额面QRS电轴随年龄增长逐渐向左(上)偏移相一致;女性V,导联的R波振幅随年龄增长而增加。结论我国成人健康人群心电图参数存在明显的年龄及性别差异,适当调整传统的正常标准,可望进一步提高心电图诊断的质量。 | 吴杰 汪道文 陆再英 徐春芳 Jan A.

| 19 | Tree diversity and nectar composition affect arthropod visitors on extrafloral nectaries in a diversity experiment显示文摘Aims Plants with extrafloral nectaries(EFNs)are common in tropical and subtropical habitats and,despite many other arthropods also forage for EFN,most studies solely focused on the defense mutualisms between EFN plants and ants.This study aims at a quantitative assessment of the entire arthropod community that visits EFN trees to compare visitor communities between different tree species to disentangle the mechanisms that may drive EFN visitor community composition.We also test for tree diversity effects on EFN visitors,as it is unknown if local tree species richness relates to the abundance and species richness of arthropods foraging for EFN.Methods We sampled EFN-visiting arthropods in the experimental tree species richness gradient of the BEF-China Experiment,the currently largest forest diversity experiment in the world,and tested if tree species richness affects EFN visitors and if visitor community composition differs between EFN tree species.In a second step,we analyzed the EFN of Ailanthus altissima and Triadica cochinchinensis,the two EFN tree species with highest visitor abundance,for sugars and amino acids(AA)to test if tree species-specific differences in nectar chemistry translate to differing visitor communities.Lastly,we conducted a choice experiment using different artificial nectar solutions to test if nectar quality affects foraging decisions of ants,the most frequent EFN visitors in our study sites.Important Findings EFN trees in young successional forests in subtropical South-East China are visited by a diverse assemblage of arthropods including ants,beetles,flies,and spiders.Albeit ants accounted for about 75%of all individuals,non-ant visitors were by far more species rich.Visitor abundance and species richness declined with increasing tree species richness,suggesting a resource dilution effect,because plots with more tree species had proportionally less EFN tree individuals and thus lower nectar availability.Ailanthus altissima and T.cochinchinensis were visited by different arthropods and their nectar had species-specific AA composition and sugar concentration,indicating that differences in visitors may,at least partly,be explained by differences in nectar chemistry.These findings are supported by the choice experiment,in which artificial nectars containing sugar solutions supplemented with essential AAs attracted more ants than pure sugar solutions or sugar solutions supplemented with non-essential AAs.Our results improve the understanding of the complex ecology of EFN trees,a plant life form that might be crucial for understanding how tree diversity influences patterns of tree growth in young successional tropical and subtropical forests. | Michael Staab Joel Methorst Jan Peters Nico Blüthgen Alexandra-Maria Klein | 2017 | Journal of Plant Ecology2017,10,1: | 6 |
| 20 | 美国国家卒中协会短暂性脑缺血发作处理指南显示文摘目的:短暂性脑缺血发作(TIA)是常见和重要的卒中先兆。其处理方法多样,大多数发表的指南在近年来均未被更新。我们试图制定一个全面的、无偏倚的、循证的TIA处理指南。方法:根据一种客观标准(可以预测在该研究领域中执业医师对专家提名的文献测量学方法)挑选出15名专家组成员。通过系统回顾检索到过去发表的指南,由专家对其中的推荐意见的质量进行独立评价。选择出质量最高的推荐意见,然后让专家组采用改良Delphi法通过多次问卷调查的方式进行修订,从而对新的修改达成共识。给专家们提供近期临床研究的系统评价,要求专家根据新的证据判断措辞修改的合理性并且根据证据等级和质量对最终的推荐意见进行评定。不允许专家在预期有可能存在任何利益冲突的专题方面提出推荐意见。结果:通过系统回顾检索到257个指南,其中有13篇文献包括的137条推荐意见符合所有纳入标准。需要6次重复的问卷调查对53条最终推荐意见的措辞达成共识。最终的推荐意见涉及TIA的初步处理、评价、内科治疗、外科治疗和危险因素控制。结论:对TIA患者医疗诊治的最终推荐意见强调了紧急评价和治疗的重要性。这种用于制定本指南的新方法是可行的,考虑到了快速更新并能减少偏倚。 | S.
