| 1 | Advanced gastric cancer:Current treatment landscape and future perspectives显示文摘Gastric cancer currently ranks fourth in cancer-related mortality worldwide. In the western world, it is most often diagnosed at an advanced stage, after becoming metastatic at distant sites. Patients with advanced disease(locally advanced or metastatic) have a somber prognosis, with a median overall survival of 10-12 mo, and palliative chemotherapy is the mainstay of treatment. In recent years, novel approaches using inhibition of human epidermal growth factor receptor 2(HER2) have demonstrated significant improvements in progression-free and overall survival, compared with chemotherapy alone, in first-line treatment of patients with overexpression of HER2. In addition, both second-line chemotherapy and treatment with the vascular endothelial growth factor receptor-inhibitor ramucirumab demonstrated significant benefits in terms of overall survival, compared with best supportive care, in randomized studies. Moreover, ramucirumab in combination with chemotherapy demonstrated further significant benefits in terms of progression-free and overall survival, compared with chemotherapy alone, in second-line treatment for patients with metastatic gastric cancer. A recently published molecular classification of gastric cancer is expected to improve patient stratification and selection for clinical trials and provide a roadmap for future drug development. Nevertheless, despite these developments the prognosis of patients with advanced gastric cancer remains poor. In this review we discuss current standards of care and outline major topics of drug development in gastric cancer. | Antonia Digklia Anna Dorothea Wagner | 2016 | World Journal of Gastroenterology2016，22，8： | 108 |
| 2 | Helicobacter pylori in dental plaque and stomach of patients from Northern Brazil显示文摘AIM: To establish whether virulence factor genes vacA and cagA are present in Helicobacter pylori (H. pylori) retrieved from gastric mucosa and dental plaque in pa-tients with dyspepsia. METHODS: Cumulative dental plaque specimens and gastric biopsies were submitted to histological exami-nation, rapid urease test and polymerase chain reac-tion (PCR) assays to detect the presence of cagA and vacA polymorphisms.RESULTS: Detection of H. pylori from dental plaque and gastric biopsy samples was greater by PCR com-pared to histological examination and the rapid ure-ase test. DNA from H. pylori was detected in 96% of gastric mucosa samples and in 72% of dental plaque samples. Sixty-three (89%) of 71 dental plaque sam-ples that were H. pylori-positive also exhibited identical vacA and cagA genotypes in gastric mucosa. The most common genotype was vacAs1bm1 and cagA positive, either in dental plaque or gastric mucosa. These viru-lent H. pylori isolates were involved in the severity of clinical outcome.CONCLUSION: These pathogenic strains were found simultaneously in dental plaque and gastric mucosa, which suggests that gastric infection is correlated with the presence of H. pylori in the mouth. | Mnica Baraúna Assumpo Luisa Caricio Martins Hivana Patricia Melo Barbosa Katarine Antonia dos Santos Barile Sintia Silva de Almeida Paulo Pimentel Assumpo Tereza Cristina de Oliveira Corvelo | 2010 | World Journal of Gastroenterology2010，16，24： | 29 |
| 3 | 新疆石人子沟遗址出土家马的DNA研究显示文摘运用古DNA技术对新疆石人子沟遗址的墓葬中出土的古代家马样本进行遗传学分析。共选取5匹家马骨骼样本,从中提取DNA并对线粒体DNA控制区和毛色控制基因的核DNA进行PCR扩增。全部样本获得了线粒体DNA序列,在这5个序列中共检测出3个不同的单倍型,可以归属到3个不同的谱系A,B和E。毛色控制基因的SNP检测结果显示石人子沟遗址古代家马有栗色(chestnut)、枣色(bay)和金黄色(palomino)3种不同毛色。尽管样本量很小,但是线粒体DNA和毛色控制基因的核DNA研究均显示出石人子沟遗址的古代家马具有较高的遗传多样性。结合古代文献记载和新疆的特殊地理位置,支持新疆是家马引入中国的一个重要通道的观点。此外,金黄色马与墓主人同葬于墓室,可能是当时特殊的选择,表明马在古代人类社会中具有着重要的地位。 | 赵欣 Antonia T Rodrigues 尤悦 王建新 马健 任萌 袁靖 杨东亚 | 2014 | 第四纪研究2014，34，1： | 19 |
| 4 | role of microRNAs in the main molecular pathways of hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC) is the most common primary liver malignant neoplasia. HCC is characterized by a poor prognosis. The need to find new molecular markers for its diagnosis and prognosis has led to a progressive increase in the number of scientific studies on this topic. MicroRNAs(miRNAs) are small noncoding RNA that play a role in almost all main cellular pathways. miRNAs are involved in the regulation of expression of the major tumor-related genes in carcinogenesis, acting as oncogenes or tumor suppressor genes. The aim of this review was to identify papers published in 2017 investigating the role of miRNAs in HCC tumorigenesis. miRNAs were classified according to their role in the main molecular pathways involved in HCC tumorigenesis:(1) m TOR;(2) Wnt;(3) JAK/STAT;(4) apoptosis; and(5) MAPK. The role of miRNAs in prognosis/response prediction was taken into consideration. Bearing in mind that the analysis of miRNAs in serum and other body fluids would be crucial for clinical management, the role of circulating miRNAs in HCC patients was also investigated. The most represented mi RNA-regulated pathway in HCC is m TOR, but apoptosis, Wnt, JAK/STAT or MAPK pathways are also influenced by mi RNA expression levels. These miRNAs could thus be used in clinical practice as diagnostic, prognostic or therapeutic targets for HCC treatment. | Francesco Vasuri Michela Visani Giorgia Acquaviva Thomas Brand Michelangelo Fiorentino Annalisa Pession Giovanni Tallini Antonia D’Errico Dario de Biase | 2018 | World Journal of Gastroenterology2018，24，25： | 16 |
| 5 | Neo-adjuvant chemo(radio)therapy in gastric cancer: Current status and future perspectives显示文摘In the last 20 years, several clinical trials on neoadjuvant chemotherapy and chemo-radiotherapy as a therapeutic approach for locally advanced gastric cancer have been performed. Even if more data are necessary to define the roles of these approaches, the results of preoperative treatments in the combined treatment of gastric adenocarcinoma are encouraging because this approach has led to a higher rate of curative surgical resection. Owing to the results of most recent randomized phase III studies, neoadjuvant chemotherapy for locally advanced resectable gastric cancer has satisfied the determination of level I evidence. Remaining concerns pertain to the choice of the optimal therapy regimen, strict patient selection by accurate pre-operative staging, standardization of surgical procedures, and valid criteria for response evaluation. New well-designed trials will be necessary to find the best therapeutic approach in pre-operative settings and the best way to combine old-generation chemotherapeutic drugs with new-generation molecules. | Alberto Biondi Maria C Lirosi Domenico D'Ugo Valeria Fico Riccardo Ricci Francesco Santullo Antonia Rizzuto Ferdinando CM Cananzi Roberto Persiani | 2015 | World Journal of Gastrointestinal Oncology2015，7，12： | 13 |
| 6 | Chronic hepatitis B: Advances in treatment显示文摘Treatment of chronic hepatitis B(CHB) has markedly improved in the last 15 years due to the availability of direct antivirals which greatly increase therapeutic options. Currently, there are two classes of agents licensed for CHB treatment: standard or pegylated interferon alpha(IFN or Peg-IFN) and five nucleoside/nucleotide analogues(NAs). Long-term treatment with NAs is the treatment option most often used in the majority of CHB patients. Entecavir and tenofovir, the most potent NAs with high barrier to resistance, are recommended as first-line monotherapy by all major treatment guidelines and can lead to long-lasting viro-logical suppression, resulting in histological improve-ment or reversal of advanced fibrosis and reduction in disease progression and liver-related complications. In this review, we focus on current treatment strategies of chronic hepatitis B and discuss the most recent efficacy and safety data from clinical trials and real life clinical practice. Recent findings of response-guided approach-es are also discussed. | Teresa Antonia Santantonio Massimo Fasano | 2014 | World Journal of Hepatology2014，6，5： | 12 |
| 7 | Role of MGMT as biomarker in colorectal cancer显示文摘O6-methylguanine DNA methyltransferase(MGMT) gene promoter methylation plays an important role in colorectal carcinogenesis, occurring in about 30%-40% of metastatic colorectal cancer. Its prognostic role has not been defined yet, but loss of expression of MGMT, which is secondary to gene promoter methylation, results in an interesting high response to alkylating agents such as dacarbazine and temozolomide. In a phase 2 study on heavily pre-treated patients with MGMT methylated metastatic colorectal cancer, temozolomide achieved about 30% of disease control rate. Activating mutations of RAS or BRAF genes as well as mismatch repair deficiency may represent mechanisms of resistance to alkylating agents, but a dose-dense schedule of temozolomide may potentially restore sensitivity in RAS-mutant patients. Further development of temozolomide in MGMT methylated colorectal cancer includes investigation of synergic combinations with other agents such as fluoropyrimidines and research for additional biomarkers, in order to better define the role of temozolomide in the treatment of individual patients. | Alessandro Inno Giuseppe Fanetti Maria Di Bartolomeo Stefania Gori Claudia Maggi Massimo Cirillo Roberto Iacovelli Federico Nichetti Antonia Martinetti Filippo de Braud Ilaria Bossi Filippo Pietrantonio | 2014 | World Journal of Clinical Cases2014，2，12： | 10 |
| 8 | Novel agents and new therapeutic approaches for treatment of multiple myeloma显示文摘This review summarizes the therapeutic strategies and the drugs actually in development for the management of myeloma patients. Multiple myeloma is caused by the expansion of monoclonal plasma cells and secretion of M-protein(immunoglobulins, Bence Jones protein and free light chains). Multiple myeloma still remains an incurable disease with a high incidence rate in the elderly, despite the introduction of several new therapeutic agents(bortezomib, lenalidomide and thalidomide) which have changed its natural history. The high heterogeneity of this disease leads to large differences in clinical responses to treatments. Thus, the choice of the best treatment is a difficult issue. However, the introduction of new drugs has made it possible to achieve high response rates and good quality respons-es with long-term disease control. Interactions between tumor cells and their bone marrow microenvironment play a pivotal role in the development, maintenance, and progression of myeloma, inducing also drug resistance. These knowledges have improved treatment options, leading to the approval of new drugs which not only target the malignant cell itself, but also its microenvironment. These agents are in preclinical/early clinical evaluation and they appear to further improve disease control, but their use is still not approved outside of clinical trials. | Roberto Ria Antonia Reale Angelo Vacca | 2014 | World Journal of Methodology2014，4，2： | 10 |
| 9 | Respiratory mechanics in brain injury: A review显示文摘Several clinical and experimental studies have shown that lung injury occurs shortly after brain damage. The responsible mechanisms involve neurogenic pulmonary edema, inflammation, the harmful action of neurotransmitters, or autonomic system dysfunction. Mechanical ventilation, an essential component of life support in brain-damaged patients(BD), may be an additional traumatic factor to the already injured or susceptible to injury lungs of these patients thus worsening lung injury, in case that non lung protective ventilator settings are applied. Measurement of respiratory mechanics in BD patients, as well as assessment of their evolution during mechanical ventilation, may lead to preclinical lung injury detection early enough, allowing thus the selection of the appropriate ventilator settings to avoid ventilatorinduced lung injury. The aim of this review is to explore the mechanical properties of the respiratory system in BD patients along with the underlying mechanisms, and to translate the evidence of animal and clinical studies into therapeutic implications regarding the mechanical ventilation of these critically ill patients. | Antonia Koutsoukou Maria Katsiari Stylianos E Orfanos Anastasia Kotanidou Maria Daganou Magdalini Kyriakopoulou Nikolaos G Koulouris Nikoletta Rovina | 2016 | World Journal of Critical Care Medicine2016，5，1： | 7 |
| 10 | Identification and Cloning of Differentially Expressed Genes Involved in the Interaction Between Potato and Phytophthora infestans using a Subtractive Hybridization and cDNA-AFLP Combinational Approach显示文摘Using a subtractive hybridization (SH)/cDNA-AFLP combinational approach,differentially expressed genes involved in the potato-Phytophthora infestans interaction were identified.These included genes potentially controlling pathogenesis or avr genes in P.infestans as well as those potentially involved in potato resistance or susceptibility to this pathogen.Forty-one differentially expressed transcriptderived fragments (TDFs),resulting from the interaction,were cloned and sequenced.Two TDFs,suggested as potential pathogenicity factors,have sequence similarity to N-succinyl diaminopimelate aminotransferase and a transcriptional regulator,TetR family gene,respectively.Two other TDFs,suggested as potential avr genes,have sequence similarity to an EST sequence from Avr4/Cf-4/Avr9/Cf9 and a P.infestans avirulence-associated gene,respectively.Genes’ expression and origin were confirmed using Southern blots,Northern blots and qRT-PCR.I.e.,potential resistance gene DL81 was induced at 12 hpi in the moderately resistant cultivar,whereas it was down-regulated as early as 6 hpi in the susceptible cultivar.On the other hand,DL21 was induced at 6 hpi (3.38-fold) in response to the highly aggressive isolate (US8) and strongly up-regulated thereafter (25.13-fold at 120 hpi.),whereas it was only slightly up-regulated in response to the weakly aggressive isolate US11 (3.82-fold at 96 hpi),suggesting its potential involvement as a susceptibility gene. | Maria Antonia Henriquez Fouad Daayf | 2010 | Journal of Integrative Plant Biology2010，52，5： | 6 |
| 11 | Acoustic radiation force impulse imaging for assessing liver fibrosis in alcoholic liver disease显示文摘AIM: To evaluate the performance of elastography by ultrasound with acoustic radiation force impulse(ARFI) in determining fibrosis stage in patients with alcoholic liver disease(ALD) undergoing alcoholic detoxification in relation to biopsy.METHODS: Eighty-three patients with ALD undergoing detoxification were prospectively enrolled. Each patient underwent ARFI imaging and a liver biopsy onthe same day. Fibrosis was staged according to the METAVIR scoring system. The median of 10 valid ARFI measurements was calculated for each patient.RESULTS: Sixty-nine males and thirteen females(one patient excluded due to insufficient biopsy size) were assessed with a mean alcohol consumption of 132.4 ± 128.8 standard drinks per week and mean cumulative year duration of 17.6 ± 9.5 years. Sensitivity and specificity were respectively 82.4%(0.70-0.95) and 83.3%(0.73-0.94)(AUROC = 0.87) for F ≥ 2 with a cut-off value of 1.63m/s; 82.4%(0.64-1.00) and 78.5%(0.69-0.89)(AUROC = 0.86) for F ≥ 3 with a cut-off value of 1.84m/s; and 92.3%(0.78-1.00] and 81.6%(0.72-0.90)(AUROC = 0.89) for F = 4 with a cut-off value of 1.94 m/s.CONCLUSION: ARFI is an accurate, non-invasive and easy method for assessing liver fibrosis in patients with ALD undergoing alcoholic detoxification. | Anita Kiani Vanessa Brun Fabrice Lainé Bruno Turlin Jeff Morcet Sophie Michalak Antonia Le Gruyer Ludivine Legros Edouard Bardou-Jacquet Yves Gandon Romain Moirand | 2016 | World Journal of Gastroenterology2016，22，20： | 6 |
| 12 | Focus on acute diarrhoeal disease显示文摘Diarrhoea is an alteration of normal bowel movement characterized by an increase in the water content, volume, or frequency of stools. Diarrhoea needs to be classif ied according to the trends over time (acute or chronic) and to the characteristics of the stools (watery, fatty, inflammatory). Secretory diarrhoeas, mostly acute and of viral aetiology in more than 70% of cases, are by far the most important subtype of diarrhoeas in terms of frequency, incidence and mortality (over 2.5 million deaths/year in developing countries). Natural and synthetic opiates such as morphine, codeine, and loperamide which react with endogenous opiates (enkephalins, beta-endorphins, dynorphins) mainly act on intestinal motility and slow down transit. An antidiarrhoeal drug developed in recent years, racecadotril, acts as an enkephalinase inhibitor. Clinical studies have shown that it is just as effective as loperamide in resolving acute diarrhoea but with greater reduction in pain and abdominal distension. Some studies have explored the prevalence of diarrhoea in old age. An epidemiological study carried out in Italy by 133 General Practitioners on 5515 elderly outpatients reported a prevalence of diarrhoea, def ined according to the Rome criteria, of 9.1%. Infectious diseases (19%) and drug use (16%) were the most common causes of diarrhoea in old age. Regardless of the cause, the treatment of elderly patients with diarrhoea must include rehydration and nutritional support. Every year, more than 50 million tourists travel from industrialized countries to places where hygiene levels are poor. At least 75% of those travelling for short periods mention health problems, and in particular traveller's diarrhoea. | Fabio Baldi Maria Antonia Bianco Gerardo Nardone Alberto Pilotto Emanuela Zamparo | 2009 | World Journal of Gastroenterology2009，15，27： | 6 |
| 13 | The role of sphingosine-1-phosphate in bone remodeling and osteoporosis显示文摘Osteoporosis is a systemic bone disease that affects more than 200 million people worldwide and is caused by the disruption of the equilibrium between osteoclastic bone resorption and osteoblastic bone formation. Sphingosine-1-phosphate(S1 P) is a natural,bioactive sphingolipid that has been shown to play a major role in cardiovascular and immunological pathologies by regulating biological and cellular processes, including migration, differentiation, proliferation and survival. Recent studies also suggest a central role for S1 P in bone diseases, including osteoporosis;however, the effects of S1 P, particularly in bone metabolism, remain to be further elucidated. In this review, we summarize the available literature on the role of S1 P in bone metabolism with a focus on osteoporosis. On the cellular level, S1 P acts as an osteoclast-osteoblast coupling factor to promote osteoblast proliferation and bone formation. Moreover, the recruitment of osteoclast precursors to resorption sites is regulated by the interplay of S1 P gradients and S1 P receptor expression. From a clinical perspective, increasing evidence suggests that systemically elevated S1 P blood levels may serve as an independent risk factor for osteoporosis-related fractures. Taken together, S1 P signaling is a potential therapeutic target and may serve as a novel biomarker in patients with systemic bone disease. | Justus M.Grewe Paul-Richard Knapstein Antonia Donat Shan Jiang Daniel JSmit Weixin Xie Johannes Keller | 2022 | Bone Research2022，10，2： | 5 |
| 14 | Expiratory flow-limitation in mechanically ventilated patients: A risk for ventilator-induced lung injury?显示文摘Expiratory flow limitation(EFL), that is the inability of expiratory flow to increase in spite of an increase of the driving pressure, is a common and unrecognized occurrence during mechanical ventilation in a variety of intensive care unit conditions. Recent evidence suggests that the presence of EFL is associated with an increase in mortality, at least in acute respiratory distress syndrome(ARDS) patients, and in pulmonary complications in patients undergoing surgery. EFL is a major cause of intrinsic positive end-expiratory pressure(PEEPi), which in ARDS patients is heterogeneously distributed, with a consequent increase of ventilation/perfusion mismatch and reduction of arterial oxygenation. Airway collapse is frequently concomitant to the presence of EFL.When airways close and reopen during tidal ventilation, abnormally high stresses are generated that can damage the bronchiolar epithelium and uncouple small airways from the alveolar septa, possibly generating the small airways abnormalities detected at autopsy in ARDS. Finally, the high stresses and airway distortion generated downstream the choke points may contribute to parenchymal injury, but this possibility is still unproven. PEEP application can abolish EFL, decrease PEEPi heterogeneity, and limit recruitment/derecruitment.Whether increasing PEEP up to EFL disappearance is a useful criterion for PEEP titration can only be determined by future studies. | Antonia Koutsoukou Matteo Pecchiari | 2019 | World Journal of Critical Care Medicine2019，8，1： | 5 |
| 15 | Surgical resection of a solitary liver metastasis from nasopharyngeal carcinoma: a case report显示文摘BACKGROUND: Nasopharyngeal carcinoma (NPC) has a propensity to develop distant metastases at a high rate and with poor prognosis. Metastatic sites are usually multifocal and involve bones, lungs, liver and distant lymph nodes. Management of metastatic disease is essentially palliative and is based on chemotherapy. METHODS: A 50-year-old man with a solitary liver metastasis from a newly diagnosed NPC was treated by segmentectomy. Prior to surgery, neoadjuvant chemo therapy followed by concurrent chemoradiotherapy was administered. RESULTS: Complete remission of the primary disease was achieved, although the size of the hepatic lesion was increased. After resection of the liver metastasis, no signs of local or distant recurrence was noted during the 6-month follow up. CONCLUSION: Although surgical treatment has a limited role in metastatic NPC, there are rare cases of localized disease with a reasonable outcome after resection. | Spiros Delis Ioannis Biliatis Antonia Bourli Nikolaos Kapranos Christos Dervenis | 2006 | Hepatobiliary & Pancreatic Diseases International2006，5，4： | 4 |
| 16 | Identify multiple myeloma stem cells: Utopia?显示文摘Multiple myeloma(MM) is a hematologic malignancy of monoclonal plasma cells which remains incurable despite recent advances in therapies. The presence of cancer stem cells(CSCs) has been demonstrated in many solid and hematologic tumors, so the idea of CSCs has been proposed for MM, even if MM CSCs have not been define yet. The existence of myeloma CSCs with clonotypic B and clonotypic non B cells was postulated by many groups. This review aims to focus on these distinct clonotypic subpopulations and on their ability to develop and sustain MM. The bone marrow microenvironment provides to MM CSCs self-renewal, survival and drug resistance thanks to the presence of normal and cancer stem cell niches. The niches and CSCs interact each other through adhesion molecules and the interplay between ligands and receptors activate stemness signaling(Hedgehog, Wnt and Notch pathways). MM CSCs are also supposed to be responsible for drug resistance that happens in three steps from the initial cancer cell homing microenvironment-mediated to development of microenvironment-independent drug resistance. In this review, we will underline all these aspects of MM CSCs. | Ilaria Saltarella Aurelia Lamanuzzi Antonia Reale Angelo Vacca Roberto Ria | 2015 | World Journal of Stem Cells2015，7，1： | 4 |
| 17 | BK nephropathy in the native kidneys of patients with organ transplants: Clinical spectrum of BK infection显示文摘Nephropathy secondary to BK virus, a member of the Papoviridae family of viruses, has been recognized for some time as an important cause of allograft dysfunction in renal transplant recipients. In recent times, BK nephropathy(BKN) of the native kidneys has being increasingly recognized as a cause of chronic kidney disease in patients with solid organ transplants, bone marrow transplants and in patients with other clinical entities associated with immunosuppression. In such patients renal dysfunction is often attributed to other factors including nephrotoxicity of medications used to prevent rejection of the transplanted organs. Renal biopsy is required for the diagnosis of BKN. Quantitation of the BK viral load in blood and urine are surrogate diagnostic methods. The treatment of BKN is based on reduction of the immunosuppressive medications. Several compounds have shown antiviral activity, but have not consistently shown to have beneficial effects in BKN. In addition to BKN, BK viral infection can cause severe urinary bladder cystitis, ureteritis and urinary tract obstruction as well as manifestations in other organ systems including the central nervous system, the respiratory system, the gastrointestinal system and the hematopoietic system. BK viral infection has also been implicated in tumorigenesis. The spectrum of clinical manifestations from BK infection and infection from other members of the Papoviridae family is widening. Prevention and treatment of BK infection and infections from other Papovaviruses are subjects of intense research. | Darlene Vigil Nikifor K Konstantinov Marc Barry Antonia M Harford Karen S Servilla Young Ho Kim Yijuan Sun Kavitha Ganta Antonios H Tzamaloukas | 2016 | World Journal of Transplantation2016，6，3： | 4 |
| 18 | Strongly enhanced light trapping in a two-dimensional silicon nanowire random fractal array显示文摘We report on the unconventional optical properties exhibited by a two-dimensional array of thin Si nanowires arranged in a random fractal geometry and fabricated using an inexpensive,fast and maskless process compatible with Si technology.The structure allows for a high light-trapping efficiency across the entire visible range,attaining total reflectance values as low as 0.1%when the wavelength in the medium matches the length scale of maximum heterogeneity in the system.We show that the random fractal structure of our nanowire array is responsible for a strong in-plane multiple scattering,which is related to the material refractive index fluctuations and leads to a greatly enhanced Raman scattering and a bright photoluminescence.These strong emissions are correlated on all length scales according to the refractive index fluctuations.The relevance and the perspectives of the reported results are discussed as promising for Si-based photovoltaic and photonic applications. | Barbara Fazio Pietro Artoni Maria Antonia Iatì Cristiano D’Andrea Maria JosèLo Faro Salvatore Del Sorbo Stefano Pirotta Pietro Giuseppe Gucciardi Paolo Musumeci Cirino Salvatore Vasi Rosalba Saija Matteo Galli Francesco Priolo Alessia Irrera | 2016 | Light(Science & Applications)2016，5，1： | 4 |
| 19 | De novo autoimmune hepatitis in liver transplant: State-of-the-art review显示文摘In the two past decades, a number of communications, case-control studies, and retrospective reports have appeared in the literature with concerns about the development of a complex set of clinical, laboratory and histological characteristics of a liver graft dysfunction that is compatible with autoimmune hepatitis. The de novo prefix was added to distinguish this entity from a pre-transplant primary autoimmune hepatitis, but the globally accepted criteria for the diagnosis of autoimmune hepatitis have been adopted in the diagnostic algorithm. Indeed, de novo autoimmune hepatitis is characterized by the typical liver necroinflammation that is rich in plasma cells, the presence of interface hepatitis and the consequent laboratory findings of elevations in liver enzymes, increases in serum gamma globulin and the appearance of nonorgan specific auto-antibodies. Still, the overall features of de novo autoimmune hepatitis appear not to be attributable to a univocal patho-physiological pathway because they can develop in the patients who have undergone liver transplantation due to different etiologies. Specifically, in subjects with hepatitis C virus recurrence, an interferon-containing antiviral treatment has been indicated as a potential inception of immune system derangement. Herein, we attempt to review the currently available knowledge about de novo liver autoimmunity and its clinical management. | Ranka Vukotic Giovanni Vitale Antonia D'Errico-Grigioni Luigi Muratori Pietro Andreone | 2016 | World Journal of Gastroenterology2016，22，10： | 4 |
| 20 | Fibroadhesive scarring of grafted collagen scaffolds interferes with implant–host neural tissue integration and bridging in experimental spinal cord injury显示文摘Severe traumatic spinal cord injury(SCI)results in a devastating and permanent loss of function,and is currently an incurable condition.It is generally accepted that future intervention strategies will require combinational approaches,including bioengineered scaffolds,to support axon growth across tissue scarring and cystic cavitation.Previously,we demonstrated that implantation of a microporous type-I collagen scaffold into an experimental model of SCI was capable of supporting functional recovery in the absence of extensive implant–host neural tissue integration.Here,we demonstrate the reactive host cellular responses that may be detrimental to neural tissue integration after implantation of collagen scaffolds into unilateral resection injuries of the adult rat spinal cord.Immunohistochemistry demonstrated scattered fibroblast-like cell infiltration throughout the scaffolds as well as the presence of variable layers of densely packed cells,the fine processes of which extended along the graft–host interface.Few reactive astroglial or regenerating axonal profiles could be seen traversing this layer.Such encapsulation-type behaviour around bioengineered scaffolds impedes the integration of host neural tissues and reduces the intended bridging role of the implant.Characterization of the cellular and molecular mechanisms underpinning this behaviour will be pivotal in the future design of collagen-based bridging scaffolds intended for regenerative medicine. | Haktan Altinova Sebastian Hammes Moniek Palm Jose Gerardo-Nava Pascal Achenbach Ronald Deumens Emmanuel Hermans Tobias Fuhrmann Arne Boecker Sabien Geraldine Antonia van Neerven Ahmet Bozkurt Joachim Weis Gary Anthony Brook | 2019 | Regenerative Biomaterials2019，6，2： | 4 |
