| 1 | Colorectal cancer vaccines: Tumor-associated antigens vs neoantigens显示文摘Therapeutic options for the treatment of colorectal cancer(CRC) are diverse but still not always satisfying. Recent success of immune checkpoint inhibition treatment for the subgroup of CRC patients suffering from hypermutated tumors suggests a permanent role of immune therapy in the clinical management of CRC. Substantial improvement in treatment outcome could be achieved by development of efficient patient-individual CRC vaccination strategies. This mini-review summarizes the current knowledge on the two general classes of targets: tumor-associated antigens(TAAs) and tumorspecific antigens. TAAs like carcinoembryonic antigen and melanoma associated antigen are present in and shared by a subgroup of patients and a variety of clinical studies examined the efficacy of different TAA-derived peptide vaccines. Combinations of several TAAs as the next step and the development of personalized TAA-based peptide vaccines are discussed. Improvements of peptidebased vaccines achievable by adjuvants and immunestimulatory chemotherapeutics are highlighted. Finally, we sum up clinical studies using tumor-specific antigens-in CRC almost exclusively neoantigens-which revealed promising results; particularly no severe adverse events were reported so far. Critical progress for clinical outcomes can be expected by individualizing neoantigen-based peptide vaccines and combining them with immunestimulatory chemotherapeutics and immune checkpoint inhibitors. In light of these data and latest developments, truly personalized neoantigen-based peptide vaccines can be expected to fulfill modern precision medicine's requirements and will manifest as treatment pillar for routine clinical management of CRC. | Sandra Wagner Christina S Mullins Michael Linnebacher | 2018 | World Journal of Gastroenterology2018，24，48： | 10 |
| 2 | Compared efficacy of preservation solutions on the outcome of liver transplantation:Meta-analysis显示文摘AIM To compare the effects of the four most commonly used preservation solutions on the outcome of liver transplantations.METHODS A systematic literature search was performed using MEDLINE, Scopus, EMBASE and the Cochrane Library databases up to January 31^(st), 2017. The inclusion criteria were comparative, randomized controlled trials(RCTs) for deceased donor liver(DDL) allografts with adult and pediatric donors using the gold standard University of Wisconsin(UW) solution or histidinetryptophan-ketoglutarate(HTK), Celsior(CS) and Institut Georges Lopez(IGL-1) solutions. Fifteen RCTs(1830 livers) were included; the primary outcomes were primary non-function(PNF) and one-year posttransplant graft survival(OGS-1). RESULTS All trials were homogenous with respect to donor and recipient characteristics. There was no statistical difference in the incidence of PNF with the use of UW, HTK, CS and IGL-1(RR = 0.02, 95%CI: 0.01-0.03, P = 0.356). Comparing OGS-1 also failed to reveal any difference between UW, HTK, CS and IGL-1(RR = 0.80, 95%CI: 0.80-0.80, P = 0.369). Two trials demonstrated higher PNF levels for UW in comparison with the HTK group, and individual studies described higher rates of biliary complications where HTK and CS were used compared to the UW and IGL-1 solutions. However, the meta-analysis of the data did not prove a statistically significant difference: the UW, CS, HTK and IGL-1 solutions were associated with nearly equivalent outcomes.CONCLUSION Alternative solutions for UW yield the same degree of safety and effectiveness for the preservation of DDLs, but further well-designed clinical trials are warranted. | Agnes Lilla Szilágyi Péter Mátrai Péter Hegyi Eszter Tuboly Daniella Pécz András Garami Margit Solymár Erika Pétervári Márta Balaskó Gábor Veres László Czopf Bastian Wobbe Dorottya Szabó Juliane Wagner Petra Hartmann | 2018 | World Journal of Gastroenterology2018，24，16： | 5 |
| 3 | Use of shear wave elastography for the diagnosis and follow-up of biliary atresia: A meta-analysis显示文摘BACKGROUND Timely differentiation of biliary atresia(BA)from other infantile cholestatic diseases can impact patient outcomes.Additionally,non-invasive staging of fibrosis after Kasai hepatoportoenterostomy has not been widely standardized.Shear wave elastography is an ultrasound modality that detects changes in tissue stiffness.The authors propose that the utility of elastography in BA can be elucidated through meta-analysis of existing studies.AIM To assess the utility of elastography in:(1)BA diagnosis,and(2)post-Kasai fibrosis surveillance.METHODS A literature search identified articles that evaluated elastography for BA diagnosis and for post-Kasai follow-up.Twenty studies met criteria for meta-analysis:Eleven for diagnosis and nine for follow-up post-Kasai.Estimated diagnostic odds ratio(DOR),sensitivity,and specificity of elastography were calculated through a random-effects model using Meta-DiSc software.RESULTS Mean liver stiffness in BA infants at diagnosis was significantly higher than in non-BA,with overall DOR 24.61,sensitivity 83%,and specificity 79%.Post-Kasai,mean liver stiffness was significantly higher in BA patients with varices than in patients without,with DOR 16.36,sensitivity 85%,and specificity 76%.Elastography differentiated stage F4 fibrosis from F0-F3 with DOR of 70.03,sensitivity 96%,and specificity 89%.Elastography also differentiated F3-F4 fibrosis from F0-F2 with DOR of 24.68,sensitivity 85%,and specificity 81%.CONCLUSION Elastography has potential as a non-invasive modality for BA diagnosis and surveillance post-Kasai.This paper’s limitations include inter-study method heterogeneity and small sample sizes.Future,standardized,multi-center studies are recommended. | Ellen S Wagner Hussien Ahmed H Abdelgawad Meghan Landry Belal Asfour Mark B Slidell Ruba Azzam | 2022 | World Journal of Gastroenterology2022，28，32： | 5 |
| 4 | Dysfunctional stem and progenitor cells impair fracture healing with age显示文摘Successful fracture healing requires the simultaneous regeneration of both the bone and vasculature;mesenchymal stem cells (MSCs) are directed to replace the bone tissue, while endothelial progenitor cells (EPCs) form the new vasculature that supplies blood to the fracture site. In the elderly, the healing process is slowed, partly due to decreased regenerative function of these stem and progenitor cells. MSCs from older individuals are impaired with regard to cell number, proliferative capacity, ability to migrate, and osteochondrogenic differentiation potential. The proliferation, migration and function of EPCs are also compromised with advanced age. Although the reasons for cellular dysfunction with age are complex and multidimensional, reduced expression of growth factors, accumulation of oxidative damage from reactive oxygen species, and altered signaling of the Sirtuin-1 pathway are contributing factors to aging at the cellular level of both MSCs and EPCs. Because of these geriatric-specific issues, effective treatment for fracture repair may require new therapeutic techniques to restore cellular function. Some suggested directions for potential treatments include cellular therapies, pharmacological agents, treatments targeting age-related molecular mechanisms, and physical therapeutics. Advanced age is the primary risk factor for a fracture, due to the low bone mass and inferior bone quality associated with aging;a better understanding of the dysfunctional behavior of the aging cell will provide a foundation for new treatments to decrease healing time and reduce the development of complications during the extended recovery from fracture healing in the elderly. | Diane R Wagner Sonali Karnik Zachary J Gunderson Jeffery J Nielsen Alanna Fennimore Hunter J Promer Jonathan W Lowery M Terry Loghmani Philip S Low Todd O McKinley Melissa A Kacena Matthias Clauss Jiliang Li | 2019 | World Journal of Stem Cells2019，11，6： | 3 |
| 5 | Sex-specific effects of Eugenia punicifolia extract on gastric ulcer healing in rats显示文摘AIM To evaluate the sex-specific effects of a hydroalcoholic extract from Eugenia punicifolia(HEEP) leaves on gastric ulcer healing.METHODS In this rat study involving males, intact(cycling) females, and ovariectomized females, gastric ulcers were induced using acetic acid. A vehicle, lansoprazole, or HEEP was administered for 14 d after ulcer induction. Body weight was monitored throughout the treatment period. At the end of treatment, the rats were euthanized and the following in vivo and in vitro investigations were performed: macroscopic examination of the lesion area and organ weights, biochemical analysis, zymography, and evaluation of protein expression levels. Additionally, the concentration-dependent effect of HEEP was evaluated in terms of subacute toxicity and cytotoxicity.RESULTS Compared to the vehicle, HEEP demonstrated a great healing capacity by substantially reducing the ulcerative lesion area in males(52.44%), intact females(85.22%), and ovariectomized females(65.47%), confirming that HEEP accelerates the healing of acetic acidinduced gastric lesions and suggesting that this effect is modulated by female sex hormones. The antiulcer effect of HEEP was mediated by prostaglandin E2 only in male rats. Overall, the beneficial effect of HEEP was the highest in intact females. Notably, HEEP promoted the expression of vascular endothelial growth factor(intact vs ovariectomized females) and decreased the expression of Caspase-8 and Bcl-2(intact female vs male or ovariectomized female). Additionally, HEEP enhanced fibroblast proliferation and migration into a wounded area in vitro, confirming its healing effect. Finally, no sign of subacute toxicity or cytotoxicity of HEEP was observed.CONCLUSION In gastric ulcers, HEEP-induced healing(modulated by female sex hormones; in males, mediated by prostaglandin) involves extracellular matrix remodeling, with gastric mucosa cell proliferation and migration. | Larissa Lucena Périco Vinícius Peixoto Rodrigues Rie Ohara Gabriela Bueno Vania Vasti Alfieri Nunes Raquel Cássia dos Santos Ana Carolina Lima Camargo Luis Antuio Justulin Joior Sérgio Faloni de Andrade Viviane Miranda Bispo Steimbach Luísa Mota da Silva Lúcia Regina Machado da Rocha Wagner Vilegas Catarina dos Santos Clélia Akiko Hiruma-Lima | 2018 | World Journal of Gastroenterology2018，24，38： | 3 |
