1Feasibility and safety of autologous bone marrow mononuclear cell transplantation in patients with advanced chronic liver disease显示文摘AIM: To evaluate the safety and feasibility of bone marrow cell (BMC) transplantation in patients with chronic liver disease on the waiting list for liver transplantation. METHODS: Ten patients (eight males) with chronic liver disease were enrolled to receive infusion of autologous bone marrow-derived cells. Seven patients were classified as Child-Pugh B and three as Child-Pugh C. Baseline assessment included complete clinical and laboratory evaluation and abdominal MRI. Approximately 50 ml of bone marrow aspirate was prepared by centrifugation in a ficoll-hypaque gradient. At least of 100 millions of mononuclear-enriched BMCs were infused into the hepatic artery using the routine technique for arterial chemoembolization for liver tumors. Patients were followed up for adverse events up to 4 mo. RESULTS: The median age of the patients was 52 years (range 24-70 years). All patients were discharged 48 h after BMC infusion. Two patients complained ofmild pain at the bone marrow needle puncture site. No other complications or specific side effects related to the procedure were observed. Bilirubin levels were lower at 1 (2.19 ± 0.9) and 4 mo (2.10 ± 1.0) after cell transplantation that baseline levels (2.78 ± 1.2). Albumin levels 4 mo after BMC infusion (3.73 ± 0.5) were higher than baseline levels (3.47 ± 0.5). International normalized ratio (INR) decreased from 1.48 (SD = 0.23) to 1.43 (SD = 0.23) one month after cell transplantation. CONCLUSION: BMC infusion into hepatic artery of patients with advanced chronic liver disease is safe and feasible. In addition, a decrease in mean serum bilirubin and INR levels and an increase in albumin levels are observed. Our data warrant further studies in order to evaluate the effect of BMC transplantation in patients with advanced chronic liver disease.Andre Castro lyra Milena Botelho Pereira Soares luiz Flavio Maia da Silva Marcos Fraga Fortes André Goyanna Pinheiro Silva Augusto César de Andrade Mota Sheilla A Oliveira Eduardo lorens Braga Wilson Andrade de Carvalho Bernd Genser Ricardo Ribeiro dos Santos luiz Guilherme Costa lyra 2007World Journal of Gastroenterology2007,13,7:21
2皮质下小血管病诊断的共识声明显示文摘血管性认知损害是用于描述一组涉及大血管和小血管的散发性和遗传性异质性疾病的诊断术语。皮质下小血管病可导致腔隙性梗死和进行性白质损害。被称为宾斯旺格病(Binswanger's disease, BD)的进行性白质损害患者构成了从单纯血管性疾病到合并神经变性病变的疾病谱。BD患者是一个相对同质性的亚组,存在缺氧缺血、腔隙性梗死和炎症,它们协同作用破坏血脑屏障和髓鞘。通过临床、脑脊液、神经心理学和影像学检查获得的多模式疾病标记物能促进该亚组患者的鉴别。本共识声明确定了一系列基于基础病理学改变的潜在生物学标记物,这将有助于诊断以及将来协作性治疗试验的患者选择。Gary A Rosenberg Anders Wallin Joanna M Wardlaw Hugh S Markus Joan Montaner Leslie Wolfson Costantino Iadecola Berislav V Zlokovic Anne Joutel Martin Dichgans Marco Duering Reinhold Schmidt Amos D Korczyn Lea T Grinberg Helena C Chui Vladimir Hachinski 王训师 张劼 陈涵丰 俞娅美 徐子奇 罗本燕 2016国际脑血管病杂志2016,24,6:18
3Novel genetic markers in inflammatory bowel disease显示文摘Genetic factors play a significant role in determining inflammatory bowel disease(IBD)susceptibility.Epidemiologic data support genetic contribution to the pathogenesis of IBD,which include familial aggregation,twin studies,racial and ethnic differences in disease prevalence.Linkage studies have identified several susceptibility genes contained in different genomic regions named IBD1 to IBD9.Nucleotide oligomerization domain(NOD2)and human leukocyte antigen(HLA)genes are the most extensively studied genetic regions(IBD1 and IBD3 respectively)in IBD.Mutations of the NOD2 gene are associated with Crohn's disease(CD)and several HLA genes are associated with ulcerative colitis(UC)and CD.Toll like receptors(TLRs)have an important role in the innate immune response against infections by mediating recognition of pathogen-associated microbial patterns.Studying single-nucleotide polymorphisms(SNPs)in molecules involved in bacterial recognition seems to be essential to define genetic backgrounds at risk of IBD.Recently,numerous new genes have been identified to be involved in the genetic susceptibility to IBD:NOD1/Caspase-activation recruitment domains 4(CARD4),Chemokine ligand 20(CCL20),IL-11,and IL-18 among others.The characterization of these novel genes potentially will lead to the identification of therapeutic agents and clinical assessment of phenotype and prognosis in patients with IBD.Lorena Rodríguez-Bores Gabriela C Fonseca Marco A Villeda Jesús K Yamamoto-Furusho 2007World Journal of Gastroenterology2007,13,42:8

53D additive manufactured composite scaffolds with antibiotic-loaded lamellar fillers for bone infection prevention and tissue regeneration显示文摘Bone infections following open bone fracture or implant surgery remain a challenge in the orthopedics field.In order to avoid high doses of systemic drug administration,optimized local antibiotic release from scaffolds is required.3D additive manufactured(AM)scaffolds made with biodegradable polymers are ideal to support bone healing in non-union scenarios and can be given antimicrobial properties by the incorporation of antibiotics.In this study,ciprofloxacin and gentamicin intercalated in the interlamellar spaces of magnesium aluminum layered double hydroxides(MgAl)andα-zirconium phosphates(ZrP),respectively,are dispersed within a thermoplastic polymer by melt compounding and subsequently processed via high temperature melt extrusion AM(~190◦C)into 3D scaffolds.The inorganic fillers enable a sustained antibiotics release through the polymer matrix,controlled by antibiotics counterions exchange or pH conditions.Importantly,both antibiotics retain their functionality after the manufacturing process at high temperatures,as verified by their activity against both Gram+and Gram-bacterial strains.Moreover,scaffolds loaded with filler-antibiotic do not impair human mesenchymal stromal cells osteogenic differentiation,allowing matrix mineralization and the expression of relevant osteogenic markers.Overall,these results suggest the possibility of fabricating dual functionality 3D scaffolds via high temperature melt extrusion for bone regeneration and infection prevention.María C´amara-Torres Stacy Duarte Ravi Sinha Ainhoa Egizabal Noelia´Alvarez Maria Bastianini Michele Sisani Paolo Scopece Marco Scatto Alessandro Bonetto Antonio Marcomini Alberto Sanchez Alessandro Patelli Carlos Mota Lorenzo Moroni 2021Bioactive Materials2021,6,4:2
6FeNb在钢液中的溶化行为及在钢包精炼过程中提高Nb收得率的最佳工艺显示文摘阐述了标准铌铁(FeNb)的微观组织特性及其溶入钢液中的研究结果。在实验室的感应炉中进行了不同温度下的非连续试验,分析了固相FeNb与钢液凝固层界面的微观组织,并与原始FeNb粒子的微观组织进行了对比。这些试验研究结果可以阐释FeNb的溶解机制和它在不同炼钢温度下的融入动力学条件。标准FeNb在钢水中溶解的试验结果证实FeNb颗粒的溶解速率高于有关文献中报告的结果,它们认为FeNb粒子的熔化温度高(>1600℃),所以在其模型中假定FeNb的溶解仅是通过固相粒子的扩散实现。本项工作得到的试验证据为标准FeNb的溶解机理提供了一种新的说法:在1500~1510℃受其共晶区的熔化行为控制,在1530~1575℃温度范围内则由初始板条相的熔化行为所主导,也就是说,均低于1600℃左右的炼钢温度。根据这些研究结果和炼钢厂已有的生产经验,对于微合金化钢在二次精炼阶段加入FeNb推荐了最优的工艺。Edmundo Burgos Cruz Daniel Pallos Fridman Marcelo C Carboni Rogério Contato Guimares Marcos A Stuart Nogueira Ferdinando Luiz Cavallante 王厚昕 2010世界钢铁2010,,6:2
