Hepatobiliary Surgery and Nutrition 2022年第5期11卷 762-765页

作者： Courtney D.McGinnis Brenton I.M.Graham Peter S.Harris Kristofer S.Fritz Skaggs School of Pharmacy and Pharmaceutical Sciences University of Colorado Anschutz Medical CampusAuroraCOUSA

Alcohol-associated liver disease(ALD)is increasingly prevalent throughout the world(1).It remains the leading cause of liver-related morbidity and mortality worldwide and contributes to approximately 6%of global deaths(2).ALD encompasses a wide range of hepatic pathologies,including steatosis,steatohepatitis,fibrosis,and cirrhosis(3).Given the severe lack of therapeutic interventions available to reverse the progression of ALD,it is currently the leading indication for liver transplantation(4).Advancements within the field are needed to identify diagnostic biomarkers for early detection and to develop therapeutics to ameliorate hepatic dysfunction and pathologies associated with ALD.

Survivin(coding gene BIRC5) is a dual functional protein acting as a critical inhibitor of apoptosis(IAP) and key regulator of cell cycle progression. It is usually produced in embryonic tissues during development and undetectable in most adult *** of Survivin frequently occurs in various human cancers and increased Survivin correlates with poor clinic outcome, tumor recurrence, and therapeutic resistance. Because of its selective expression in tumor, but not normal tissues,Survivin has been recognized as an attractive target for cancer treatment. Although several therapeutic approaches targeting Survivin are actively under clinical trials in human cancers, to date no Survivin-targeted therapy has been approved for cancer treatment. Numerous studies have devoted to uncovering the underlying mechanism resulting in Survivin dysregulation at multiple levels, such as transcriptional and post-transcriptional regulation. The current article provides a literature review on the transcriptional and epigenetic regulation of Survivin expression in human cancers. We focus on the impact of DNA methylation and histone modifications, including specific lysine methylation, demethylation, and acetylation on the expression of *** latest development of epigenetic approaches targeting Survivin for cancer treatment are also discussed.

本临床实践标准述及动脉瘤性蛛网膜下腔出血患者出血后脑血管痉挛（post—hemorrhagiccerebralvasospasm,PHCV）的介入治疗。这些结论基于神经介入外科学学会的标准委员会的评估，包括使用由美国心脏协会卒中委员会和牛津大学循证医学中心提出的循证医学指南进行的文献回顾。特别关注现有介入治疗方法的安全性和有效性，包括腔内球囊血管成形术（transluminalballoonangioplasty，TBA）和动脉内血管扩张药物输注治疗（intra-arterialvasodilatorinfusiontherapy，IAVT）。评估结果显示，这些侵袭性介入治疗可能有益，并可考虑用于PHCV，如伴有脑缺血症状和最佳的药物治疗无效的患者的治疗。概括起来，IAVT对累及近端和（或）远端颅内脑循环的PHCV可能有益，而TBA则可能对累及近端颅内脑循环的PHCV有益。评估结果显示，对于上述适应证，根据美国心脏协会指南可将TBA和IAVT归为IIb级推荐和B级证据，根据牛津大学循证医学中心指南则可归为4级推荐和C级证据。

Despite the advances in the hematology field, blood transfusion-related iatrogenesis is still a major issue to be considered during such procedures due to blood antigenic incompatibility. This places pluripotent stem cells as a possible ally in the production of more suitable blood products. The present review article aims to provide a comprehensive summary of the state-of-theart concerning the differentiation of both embryonic stem cells and induced pluripotent stem cells to hematopoietic cell lines. Here, we review the most recently published protocols to achieve the production of blood cells for future application in hemotherapy, cancer therapy and basic research.
