1Changing face of hepatic encephalopathy:Role of inflammation and oxidative stress显示文摘The face of hepatic encephalopathy(HE) is changing.This review explores how this neurocognitive disorder,which is associated with both acute and chronic liver injury,has grown to become a dynamic syndrome that spans a spectrum of neuropsychological impairment,from normal performance to coma.The central role of ammonia in the pathogenesis of HE remains incontrovertible.However,over the past 10 years,the HE community has begun to characterise the key roles of inflammation,infection,and oxidative/nitrosative stress in modulating the pathophysiological effects of ammonia on the astrocyte.This review explores the current thoughts and evidence base in this area and discusses the potential role of existing and novel therapies that might abrogate the oxidative and nitrosative stresses inflicted on the brain in patients with,or at risk of developing,HE.Amit S Seyan Robin D Hughes Debbie L Shawcross 2010World Journal of Gastroenterology2010,16,27:23
2饮水微量元素与老年人群认知能力关系研究显示文摘在中国山东与河南两省农村研究了饮水中微量元素与老年人群认知能力 (CognitiveFunction)之间的关系。采用中国国标方法分析了饮水中氟、钙、硒、铝、铁、锌、镉、铅、砷微量元素和pH值 ;用老年性痴呆症 (Dementia)调查表 ,进行了≥ 6 5岁老年暴露人群认知能力的测定。调整年龄、性别和文化水平后 ,对微量元素与老年认知能力之间的关系进行直线模型、二次方模型和联合作用模型的统计分析 ,评价饮水中每种微量元素浓度对老年认知能力的影响。结果表明 ,单因素分析时发现几种微量元素对老年认知能力有明显作用。然而 ,在调整其它元素水平后 ,其中一些元素的作用消失。饮水中钙浓度对老年认知能力呈现一作用曲线 ,即随着饮水钙水平升高而认知能力增加 ;到某一点高峰后 ,又随钙水平增加而认知能力降低。而锌与镉之间存在一种相互作用 ,即在低饮水镉水平时 ,锌浓度与认知能力呈正相关 ,但在高饮水镉水平时 。梁超轲 吉荣娣 曹静祥 姜玉亭 余波 马凤 吴云鹏 应波 张妍 孙淑庄 Li Yiming Christine L Emsley Gao Sujuan Kathleen S Hall Hugh C Hendrie 2003卫生研究2003,32,5:12

4Pathophysiology of cerebral oedema in acute liver failure显示文摘Cerebral oedema is a devastating consequence of acute liver failure(ALF)and may be associated with the development of intracranial hypertension and death.In ALF,some patients may develop cerebral oedema and increased intracranial pressure but progression to lifethreatening intracranial hypertension is less frequent than previously described,complicating less than one third of cases who have proceeded to coma since the advent of improved clinical care.The rapid onset of encephalopathy may be dramatic with the development of asterixis,delirium,seizures and coma.Cytotoxic and vasogenic oedema mechanisms have been implicated with a preponderance of experimental data favouring a cytotoxic mechanism.Astrocyte swelling is the most consistent neuropathological finding in humans with ALF and ammonia plays a definitive role in the development of cytotoxic brain oedema.The mechanism(s)by which ammonia induces astrocyte swelling remains unclear but glutamine accumulation within astrocytes has led to the osmolyte hypothesis.Current evidence also supports an alternate‘Trojan horse’hypothesis,with glutamine as a carrier of ammonia into mitochondria,where its accumulation results in oxidative stress,energy failure and ultimately astrocyte swelling.Although a complete breakdown of the blood-brain barrier is not evident in human ALF,increased permeation to water and other small molecules such as ammonia has been demonstrated resulting from subtle alterations in the protein composition of paracellular tight junctions.At present,there is no fully efficacious therapy for cerebral oedema other than liver transplantation and this reflects our incomplete knowledge of the precise mechanisms underlying this process which remain largely unknown.Teresa R Scott Victoria T Kronsten Robin D Hughes Debbie L Shawcross 2013World Journal of Gastroenterology2013,19,48:8

7胸腹主动脉瘤:杂交修复术结果显示文摘目的:胸腹主动脉瘤(TAAA)的治疗依然是外科中最富挑战性的工作,特别是存在退行性变动脉瘤的老年患者同时患肺疾病更是如此。这篇更新后的单中心报道是关于我们对高危TAAA患者采用完全内脏动脉去分支化结合动脉瘤腔内隔绝的杂交修复术经验。方法:从2005年3月—2012年6月间58名患者在单中心接受解剖外内脏血管去分支化及随后的动脉瘤腔内隔绝术。内脏旁路的中位数为4支,最初的33例采用同期手术方式,而最近的25例采用分期手术。结果:患者中位年龄为69.0岁,50%为女性,所有患者存在严重合并症而不适合传统开放修复术。平均主动脉直径(6.7±1.2)cm,30 d/住院病死率、脑卒中率、永久性轻瘫/截瘫率分别为9%、0%以及4%。最近25例分期手术患者的这三种并发症率分别为4%、0%以及0%。平均随访时间(26±21)个月,内脏人工血管通畅率95.3%,所有闭塞的内脏人工血管均为肾动脉,无1例引起永久性截瘫,2例患者需再干预,1例出现Ib型内漏,1例出现III型内漏,5年免于再干预率为94%,Kaplan-Meier总体生存率为1年78%、5年62%,5年主动脉相关生存率为87%。结论:这些更新后的结果 ,继续支撑着这一观点:运用完全内脏动脉去分支联合动脉瘤腔内隔绝的杂交技术治疗高龄且不适合传统开放手术的高危TAAA患者是一种理想的选择,而采取分期手术的方式能取得更佳的结果。Gchad Hughes Nicholas D Andersen Jennifer M Hanna Richard L McCann 老启芳 2015中国普通外科杂志2015,24,6:2

9The Integrator complex controls the termination of transcription at diverse classes of gene targets显示文摘包含 INTS3 和 NABP1 或 NABP2 的建筑群开始在 DNA 损坏回答被描绘,但是他们的生物化学的功能仍然保持未知。用亲密关系纯化和 HIV 集成定序目标(HIT-Seq ) ,我们发现这些建筑群是综合者建筑群的部分,它绑 RNA 聚合酶 II 并且调整特定的目标基因。综合者作为他们在亲密地被结合的机制处理到他们的成熟形式的部分劈开 snRNAs 抄写结束。然而, HIT-Seq 表明那个综合者也绑在 3 ′以 polyadenylated 抄本复制依赖者 histones 和倡导者结束基因的近似区域。综合者子单元的弄空导致抄写结束失败, histone mRNA 处理的混乱,和 snRNAs 和 histone mRNAs 的 polyadenylation。而且,倡导者综合者的近似绑定否定地通常调整其抄本是的基因的表示 polyadenylated。到所有三个基因类的综合者招募是 DSIF 依赖的,建议那个综合者作为在 DSIF 依赖的 RNA 聚合酶 II 的结束建筑群工作暂停地点。Jeffrey R Skaar Andrea L Ferris Xiaolin Wu Anita Saraf Kum Kum Khanna Laurence Florens Michael P Washburn Stephen H Hughes Michele Pagano 2015Cell Research2015,25,3:2
