| 2 | Immune regulatory properties of multipotent mesenchymal stromal cells:Where do we stand?显示文摘Multipotent mesenchymal stromal cells (MSC) can be isolated and efficiently expanded from almost every single body tissue and have the ability of self-renewal and differentiation into various mesodermal cell lineages. Moreover, these cells are considered immunologically privileged, related to a lack of surface expression of costimulatory molecules required for complete T cell activation. Recently, it has been observed that MSC are capable of suppressing the immune response by inhibiting the maturation of dendritic cells and suppressing the function of T lymphocytes, B lymphocytes and natural killer cells in autoimmune and inflammatory diseases as a new strategy for immunosuppression. The understanding of immune regulation mechanisms by MSC is necessary for their use as immunotherapy in clinical applications for several diseases. | ênio José Bassi Carlos Alberto Mayora Aita Niels Olsen Saraiva Camara | 2011 | World Journal of Stem Cells2011，3，1： | 27 |

| 4 | miR-20b, miR-98, miR-125b-1*, and let-7e* as new potential diagnostic biomarkers in ulcerative colitis显示文摘AIM:To use microarray-based miRNA profiling of colonic mucosal biopsies from patients with ulcerative colitis (UC), Crohn's disease (CD), and controls in order to identify new potential miRNA biomarkers in inflammatory bowel disease. METHODS:Colonic mucosal pinch biopsies from the descending part were obtained endoscopically from patients with active UC or CD, quiescent UC or CD, as well as healthy controls. Total RNA was isolated and miRNA expression assessed using the miRNA microarray Geniom Biochip miRNA Homo sapiens (Febit GmbH, Heidelberg, Germany). Data analysis was carried out by principal component analysis and projection to latent structure-discriminant analysis using the SIMCA-P+12 software package (Umetrics, Umea, Sweden). The microarray data were subsequently validated by quantitative real-time polymerase chain reaction (qPCR) performed on colonic tissue samples from active UC patients (n = 20), patients with quiescent UC (n = 19), and healthy controls (n = 20). The qPCR results were analyzed with Mann-WhitneyU test.In silico prediction analysis were performed to identify potential miRNA target genes and the predicted miRNA targets were then compared with all UC associated susceptibility genes reported in the literature. RESULTS:The colonic mucosal miRNA transcriptome differs significantly between UC and controls, UC and CD, as well as between UC patients with mucosal inflammation and those without. However, no clear differences in the transcriptome of patients with CD and controls were found. The miRNAs with the strongest differential power were identified (miR-20b, miR-99a, miR-203, miR-26b, and miR-98) and found to be upregulated more than a 10-fold in active UC as compared to quiescent UC, CD, and controls. Two miRNAs, miR-125b-1* and let-7e*, were up-regulated more than 5-fold in quiescent UC compared to active UC, CD, and controls. Four of the seven miRNAs (miR-20b, miR-98, miR-125b-1*, and let-7e*) were validated by qPCR and found to be specifically upregulated in patients with UC. Usingin silico analysis we found several predicted pro-inflammatory target genes involved in various pathways, such as mitogen-activated protein kinase and cytokine signaling, which are both key signaling pathways in UC.CONCLUSION:The present study provides the first evidence that miR-20b, miR-98, miR-125b-1*, and let7e* are deregulated in patients with UC. The level of these miRNAs may serve as new potential biomarkers for this chronic disease. | Mehmet Coskun Jacob Tveiten Bjerrum Jakob Benedict Seidelin Jesper Thorvald Troelsen JΦrgen Olsen Ole Haagen Nielsen | 2013 | World Journal of Gastroenterology2013，19，27： | 19 |
| 5 | Cytoprotective role of heme oxygenase-1 and heme degradation derived end products in liver injury显示文摘The activation of heme oxygenase-1(HO-1) appears to be an endogenous defensive mechanism used by cells to reduce inflammation and tissue damage in a number of injury models. HO-1, a stress-responsive enzyme that catabolizes heme into carbon monoxide(CO), biliverdin and iron, has previously been shown to protect grafts from ischemia/reperfusion and rejection.In addition, the products of the HO-catalyzed reaction, particularly CO and biliverdin/bilirubin, have been shown to exert protective effects in the liver against a number of stimuli, as in chronic hepatitis C and in transplanted liver grafts. Furthermore, the induction of HO-1 expression can protect the liver against damage caused by a number of chemical compounds. More specifically, the CO derived from HO-1-mediated heme catabolism has been shown to be involved in the regulation of inflammation; furthermore, administration of low concentrations of exogenous CO has a protective effect against inflammation. Both murine and human HO-1 deficiencies have systemic manifestations associated with iron metabolism, such as hepatic overload(with signs of a chronic hepatitis) and iron deficiency anemia(with paradoxical increased levels of ferritin).Hypoxia induces HO-1 expression in multiple rodent,bovine and monkey cell lines, but interestingly, hypoxia represses expression of the human HO-1 gene in a variety of human cell types(endothelial cells, epithelial cells, T cells). These data suggest that HO-1 and CO are promising novel therapeutic molecules for patients with inflammatory diseases. In this review, we present what is currently known regarding the role of HO-1 in liver injuries and in particular, we focus on the implications of targeted induction of HO-1 as a potential therapeutic strategy to protect the liver against chemically induced injury. | Clarice Silvia Taemi Origassa Niels Olsen Saraiva Cmara | 2013 | World Journal of Hepatology2013，5，10： | 17 |
| 6 | Innate lymphoid cells in tissue homeostasis and diseases显示文摘Innate lymphoid cells(ILCs) are the most recently discovered family of innate immune cells. They are a part of the innate immune system, but develop from the lymphoid lineage. They lack pattern-recognition receptors and rearranged receptors, and therefore cannot directly mediate antigen specific responses. The progenitors specifically associated with the ILCs lineage have been uncovered, enabling the distinction between ILCs and natural killer cells. Based on the requirement of specific transcription factors and their patterns of cytokine production, ILCs are categorized into three subsets(ILC1, ILC2 and ILC3). First observed in mucosal surfaces, these cell populations interact with hematopoietic and non-hematopoietic cells throughout the body during homeostasis and diseases, promoting immunity, commensal microbiota tolerance, tissue repair and inflammation. Over the last 8 years, ILCs came into the spotlight as an essential cell type able to integrate diverse host immune responses. Recently, it became known that ILC subsets play a key role in immune responses at barrier surfaces, interacting with the microbiota, nutrients and metabolites. Since the liver receives the venous blood directly from the intestinal vein, the intestine and liver are essential to maintain tolerance and can rapidly respond to infections or tissue damage. Therefore, in this review, we discuss recent findings regarding ILC functions in homeostasis and disease, with a focus on the intestine and liver. | Aline Ignacio Cristiane Naffah Souza Breda Niels Olsen Saraiva Camara | 2017 | World Journal of Hepatology2017，9，23： | 12 |
| 7 | Intestinal barrier: A gentlemen's agreement between microbiota and immunity显示文摘Our body is colonized by more than a hundred trillion commensals, represented by viruses, bacteria and fungi. This complex interaction has shown that the microbiome system contributes to the host's adaptation to its environment, providing genes and functionality that give flexibility of diet and modulate the immune system in order not to reject these symbionts. In the intestine,specifically, the microbiota helps developing organ structures, participates of the metabolism of nutrients and induces immunity. Certain components of the microbiota have been shown to trigger inflammatory responses, whereas others, anti-inflammatory responses.The diversity and the composition of the microbiota,thus, play a key role in the maintenance of intestinal homeostasis and explain partially the link between intestinal microbiota changes and gut-related disorders in humans. Tight junction proteins are key molecules for determination of the paracellular permeability. In the context of intestinal inflammatory diseases, the intestinal barrier is compromised, and decreased expression and differential distribution of tight junction proteins is observed. It is still unclear what is the nature of the luminal or mucosal factors that affect the tight junctionproteins function, but the modulation of the immune cells found in the intestinal lamina propria is hypothesized as having a role in this modulation. In this review,we provide an overview of the current understanding of the interaction of the gut microbiota with the immune system in the development and maintenance of the intestinal barrier. | Andrea Moro Caricilli Angela Castoldi Niels Olsen Saraiva Cmara | 2014 | World Journal of Gastrointestinal Pathophysiology2014，5，1： | 11 |

| 10 | uPAR promotes tumor-like biologic behaviors of fibroblast-like synoviocytes through PI3K/Akt signaling pathway in patients with rheumatoid arthritis显示文摘Urokinase-type plasminogen activator receptor(uPAR),is a multifunctional receptor on cell surface,widely present in endothelial cells,fibroblasts,and a variety of malignant cells.Current studies have suggested that uPAR overexpressed on synovial tissues or in synovial fluid or plasma in patients with rheumatoid arthritis(RA).However,there are limited researches regarding the role of uPAR on fibroblast-like synoviocytes of rheumatoid arthritis(RA-FLSs)and its underlying mechanisms.Here,our studies show that the expression of uPAR protein was significantly higher in fibroblast-like synoviocytes(FLSs)from RA than those from osteoarthritis or traumatic injury patients.uPAR gene silencing significantly inhibited RA-FLSs cell proliferation,restrained cell transformation from the G0/G1 phase to S phase,aggravated cell apoptosis,interfered with RA-FLSs cell migration and invasion,and reduced activation of the PI3K/Akt signaling pathway,which may be associated withβ1-integrin.Cell supernatants from uPAR gene-silenced RA-FLSs markedly inhibited the migration and tubule formation ability of the HUVECs(a human endothelial cell line).Therefore,we demonstrate that uPAR changes the biological characteristics of RA-FLSs,and affects neoangiogenesis of synovial tissues in patients with RA.All of these may be associated with theβ1-integrin/PI3K/Akt signaling pathway.These results imply that targeting uPAR and its downstream signal pathway may provide therapeutic effects in RA. | Yan Liu Yun Feng Pan You-qiu Xue Lin-kai Fang Xing-hua Guo Xin Guo Meng Liu Bi-yao Mo Meng-ru Yang Fang Liu Yun-ting Wu Nancy Olsen Song Guo Zheng | 2018 | Cellular & Molecular Immunology2018，15，2： | 9 |

| 12 | Circulating inflammatory factors associated with worse long-term prognosis in colorectal cancer显示文摘AIM To investigate association of circulating inflammatory factors at the time of colorectal cancer(CRC) surgery with survival.METHODS Plasma levels from 174 CRC patients(69 females and 105 men), with median age 70 years(range 29-90), localized in the colon(n = 105) or rectum(n = 69), with stage Ⅰ(n = 24), stage Ⅱ(n = 54), stage Ⅲ(n = 67) and stage Ⅳ(n = 29) were measured using commercially available Bio-Plex Pro? Human Chemokine Panel 40-Plex, including 40 different chemokines, cytokines and interleukins. The prognostic association of each inflammatory factor was analysed as CRC-specific and total mortality.RESULTS Out of 174 patients, 66 died during the follow-up, 40 because of CRC specific mortality. High tertile levels of 8 factors were significantly associated with increased CRC-specific mortality, of which CCL1, CCL20, CCL24, CX3CL1, IL-4 and TNF-α remained significant in a multivariate Cox regression analysis. High tertile levels of 14 factors were associated with increased total mortality, of which CCL1, CCL15, CCL20, CX3CL1, CXCL13, IFN-γ, IL-2, IL-4 and IL-10 remained significant after adjustment for clinical covariates. For most of the inflammatory factors the association between higher tertile levels and an increased mortality in general appeared two years after surgery. High tertile levels of TNF-α and CCL24 were exclusively associated with CRC-specific mortality. The distribution of these factors were not associated with TNM stage with exception for CCL20.CONCLUSION High plasma levels of inflammatory factors are associated with increased risk of mortality among CRC patients and could be potential biomarkers for revealing prognosis. | Renate S Olsen Johnny Nijm Roland E Andersson Jan Dimberg Dick Wagsater | 2017 | World Journal of Gastroenterology2017，23，34： | 8 |

| 14 | Obesity in kidney disease:A heavyweight opponen显示文摘Obesity is an important worldwide challenge that must be faced in most developed and developing countries because of unhealthy nutritional habits.The consequences of obesity and being overweight are observed in different organs,but the kidney is one of the most affected.Excess adipose tissue causes hemodynamic alterations in the kidney that can result in renal disease.However,obesity is also commonly associated with other comorbidities such as chronic inflammation,hypertension and diabetes.This association of several aggravating factors is still a matter of concern in clinical and basic research because the pathophysiologic mechanisms surrounding chronic kidney disease development in obese patients remain unclear.This review will discuss the consequences of obesity in the context of renal injury. | Raphael Jose Ferreira Felizardo Marina Burgos da Silva Cristhiane Favero Aguiar Niels Olsen Saraiva Camara | 2014 | World Journal of Nephrology2014，3，3： | 7 |
| 15 | High salt diet accelerates the progression of murine lupus through dendritic cells via the p38 MAPK and STAT1 signaling pathways显示文摘The increased incidence of systemic lupus erythematosus(SLE)in recent decades might be related to changes in modern dietary habits.Since sodium chloride(NaCl)promotes pathogenic T cell responses,we hypothesize that excessive salt intake contributes to the increased incidence of autoimmune diseases,including SLE.Given the importance of dendritic cells(DCs)in the pathogenesis of SLE,we explored the influence of an excessive sodium chloride diet on DCs in a murine SLE model.We used an induced lupus model in which bone marrow-derived dendritic cells(BMDCs)were incubated with activated lymphocyte-derived DNA(ALD-DNA)and transferred into C57BL/6 recipient mice.We observed that a high-salt diet(HSD)markedly exacerbated lupus progression,which was accompanied by increased DC activation.NaCl treatment also stimulated the maturation,activation and antigenpresenting ability of DCs in vitro.Pretreatment of BMDCs with NaCl also exacerbated BMDC-ALD-DNA-induced lupus.These mice had increased production of autoantibodies and proinflammatory cytokines,more pronounced splenomegaly and lymphadenopathy,and enhanced pathological renal lesions.The p38 MAPK–STAT1 pathway played an important role in NaClinduced DC immune activities.Taken together,our results demonstrate that HSD intake promotes immune activation of DCs through the p38 MAPK–STAT1 signaling pathway and exacerbates the features of SLE.Thus,changes in diet may provide a novel strategy for the prevention or amelioration of lupus or other autoimmune diseases. | Ze Xiu Xiao Xiaojiang Hu Ximei Zhang Zhigang Chen Julie Wang Ke Jin Feng Lin Cao Baoqing Sun Joseph A.Bellanti Nancy Olsen Song Guo Zheng | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 6 |
| 16 | 鱼类消化道菌群与碳水化合物代谢显示文摘碳水化合物氧化分解是鱼类能量的重要来源。由于碳水化合物来源广泛、价格相对低廉,饲料中添加适量碳水化合物,不仅可以降低饲料成本,而且可以节约蛋白原料,减少氨氮排放。然而以往研究表明,鱼类摄入超量碳水化合物时会出现抗病力受损、生长迟缓、脂肪肝、死亡率升高等问题。鱼类消化道微生物参与宿主的糖、脂类和蛋白质等代谢过程,对动物营养代谢有重要的调控作用。提高鱼类对饲料的利用率,对鱼类增产、渔民增收具有重要的现实意义。本研究综述了鱼类对碳水化合物的代谢,以鱼类消化道微生物为出发点,阐述了鱼类消化道微生物调控碳水化合物代谢的方式与可能机制,旨在为鱼类高效利用碳水化合物以及节约饲料中蛋白质提供新视角。 | 鲁程瑶 丁倩雯 冉超 杨雅麟 王安然 张洪玲 张进雄 李解 ERIK Olsen Rolf EINAR Ringo 张震 周志刚 | 2019 | 水产学报2019，43，10： | 6 |
| 17 | Primary total elbow arthroplasty in complex fractures of the distal humerus显示文摘AIM:To evaluate short-to medium term outcome of total elbow arthroplasty(TEA)in complex fractures of the distal humerus.METHODS:A consecutive series of 24 complex distal humerus fractures operated with TEA in the period2006-2012 was evaluated with the Mayo Elbow Performance score(MEPS),plain radiographs,complications and overall satisfaction.The indications for surgery were 1:AO type B3 or C3 or Sheffield type 3 fracture and age above 65 or 2:fracture and severe rheumatoid arthritis.Mean follow-up time was 21 mo.RESULTS:Twenty patients were followed up.Four patients,of which 3 had died,were lost to follow up.According to the AO classification there were 17 C3,1B2 and 2 A2 fractures.Mean follow-up was 21 months(range 4-54).Mean MEPS was 94(range 65-100).Mean flexion was 114 degrees(range 80-140).According to MEPS there were 15 excellent,4 good and 1 fair result.Patient satisfaction:8 excellent,10 good,2 fair and 1poor.There were two revisions due to infection treated successfully with revision and three months of antibiotics.In two patients the locking split had loosened.One was referred to re-insertion and one chose yearly con-trols.Two patients had persistent dysaesthesia of their5th finger,but were able to discriminate between sharp and blunt.CONCLUSION:Our study suggests that TEA in complex fractures of the distal humerus in elderly patients can result in acceptable short-to medium term outcome. | Brian Weng S?rensen Stig Brorson Bo Sanderhoff Olsen | 2014 | World Journal of Orthopedics2014，5，3： | 5 |
| 18 | Initial scalar lithospheric magnetic anomaly map of China and surrounding regions derived from CSES satellite data显示文摘The China Seismo-Electromagnetic Satellite(CSES),China’s first satellite to measure geophysical fields with scientific goals in both space and solid earth physics,was launched successfully in February 2018.It carries high-precision magnetometers to measure the geomagnetic field.In this study,the CSES magnetic data were used to extract the signal of the lithospheric magnetic field caused by magnetized rocks in the crust and uppermost mantle.First,an along-track analysis of the CSES magnetic data was undertaken near the Bangui magnetic anomaly in central Africa and the Tarim magnetic anomaly in China,demonstrating that the CSES magnetic data are indeed sensitive to the lithospheric magnetic anomaly field.Then a lithospheric magnetic anomaly map over China and surrounding regions was derived.This map is consistent with the lithospheric part of the CHAOS-7 model.In particular,it clearly reveals four major magnetic anomalies containing long-wavelength signals at the altitude of lowearth-orbiting satellites.Three magnetic highs are located over the Tarim,Sichuan and Songliao basin,the origins of which could be related to large-scale tectonic-magmatic activities during geological history.A prominent magnetic low is otherwise found in the southern Himalayan-Tibetan plateau,possibly caused by the shallow Curie depth in this region.To further improve the precision of the lithospheric magnetic field model,more detailed data processing and multi-source data merging are needed. | WANG Jie SHEN XuHui YANG YanYan ZEREN ZhiMa HULOT Gauthier OLSEN Nils ZHOU Bin MAGNES Werner DE SANTIS Angelo HUANG JianPing GUO Feng LIU WenLong YU JingBo | 2021 | Science China(Technological Sciences)2021，64，5： | 4 |
