| 1 | Oxidative stress and male reproductive health显示文摘有缺点的精子功能的主要原因之一是氧化应力,它不仅破坏精子 DNA 的正直而且在精子血浆膜由于蛋白质和类脂化合物的并行的损坏限制这些房间的使肥沃的潜力。如此的氧化压力的起源看起来包含精子线粒体,它有一个趋势作为一篇序言产生 superoxide 阴离子的高水平到进入内在的 apoptotic 串联。不幸地,这些房间有很小的能力因为他们仅仅在基础切除修理(BER ) 拥有第一酶,对如此的攻击作出回应小径, 8-oxoguanine glycosylase 1 (OGG1 ) 。后者成功地创造一个 abasic 地点,而是精子因为他们缺乏下游的蛋白质,不能进一步处理氧化损害(APE1, XRCC1 ) 需要完成修理过程。在第一个有丝分裂的部门的 S 阶段的开始以前继续 BER 小径是卵母细胞的责任。如果一个错误被卵母细胞在开发的这个阶段犯,一个变化将被创造那将在身体在每个房间被代表。如此的机制可以在在作为年龄的后果在他们的细菌线承受了氧化应力的男性的后代观察的童年癌症和另外的疾病解释增加,环境或生活方式因素。在男不孕病人的精子的氧化 DNA 损坏的高流行可以为在 vitro 构思的孩子的健康有含意并且在细菌线为对免费激进的产生的起源的当前的研究担任一位司机。 | Robert J Aitken Tegan B Smith Matthew S Jobling Mark A Baker Geoffry N De Iuliis | 2014 | Asian Journal of Andrology2014,16,1: | 48 |
| 2 | Current state of laparoscopic parastomal hernia repair:A meta-analysis显示文摘AIM:To evaluate the efficacy and safety of the laparoscopic approaches for parastomal hernia repair reported in the literature.METHODS:A systematic review of PubMed and MEDLINE databases was conducted using various combination of the following keywords:stoma repair,laparoscopic,parastomal,and hernia.Case reports,studies with less than 5 patients,and articles not written in English were excluded.Eligible studies were further scrutinized with the 2011 levels of evidence from the Oxford Centre for Evidence-Based Medicine.Two authors reviewed and analyzed each study.If there was any discrepancy between scores,the study in question was referred to another author.A meta-analysis was performed using both random and fixed-effect models.Publication bias was evaluated using Begg's funnel plot and Egger's regression test.The primary outcome analyzed was recurrence of parastomal hernia.Secondary outcomes were mesh infection,surgical site infection,obstruction requiring reoperation,death,and other complications.Studies were grouped by operative technique where indicated.Except for recurrence,most postoperative morbidities were reported for the overall cohort and not by approach so they were analyzed across approach.RESULTS:Fifteen articles with a total of 469 patients were deemed eligible for review.Most postoperative morbidities were reported for the overall cohort,and not by approach.The overall postoperative morbidity rate was 1.8%(95%CI:0.8-3.2),and there was no difference between techniques.The most common postoperative complication was surgical site infection,which was seen in 3.8%(95%CI:2.3-5.7).Infected mesh was observed in 1.7%(95%CI:0.7-3.1),and obstruction requiring reoperation also occurred in 1.7%(95%CI:0.7-3.0).Other complications such as ileus,pneumonia,or urinary tract infection were noted in16.6%(95%CI:11.9-22.1).Eighty-one recurrences were reported overall for a recurrence rate of 17.4%(95%CI:9.5-26.9).The recurrence rate was 10.2%(95%CI:3.9-19.0) for the modified laparoscopic Sugarbaker approach,whereas the recurrence rate was27.9%(95%CI:12.3-46.9) for the keyhole approach.There were no intraoperative mortalities reported and six mortalities during the postoperative course.CONCLUSION:Laparoscopic intraperitoneal mesh repair is safe and effective for treating parastomal hernia.A modified Sugarbaker approach appears to provide the best outcomes. | Francis J DeAsis Brittany Lapin Matthew E Gitelis Michael B Ujiki | 2015 | World Journal of Gastroenterology2015,21,28: | 34 |
| 3 | 肌萎缩性侧索硬化蛋白激活小胶质细胞NLRP3炎性小体显示文摘小胶质细胞NLRP3炎性小体激活正在成为神经退行性变过程中神经炎症的关键因素。诸如β-淀粉样蛋白和α-突触核蛋白之类的致病性蛋白质聚集体触发小胶质NLRP3激活,从而导致半胱天冬酶-1激活和IL-1β的分泌。在小鼠肌萎缩性侧索硬化症(ALS)的SOD1G93A模型中,半胱天冬酶-1和IL-1β均促进疾病进展,提示小胶质NLRP3在该进程中发挥作用。然而先前的研究表明,SOD1G93A小鼠小胶质细胞不表达NLRP3,SOD1G93A蛋白在小胶质细胞中产生独立于NLRP3的IL-1β。本研究论证了使用Nlrp3-GFP基因敲入小鼠,在SOD1G93A小鼠中小胶质细胞表达NLRP3。本研究显示聚集和可溶性SOD1G93A均可激活小鼠原代小胶质细胞中的炎性小体,导致半胱天冬酶-1和IL-1β裂解,ASC斑点形成以及呈剂量和时间依赖性的IL-1β分泌。重要的是,SOD1G93A无法从缺乏Nlrp3的小胶质细胞或者用特异性NLRP3抑制剂MCC950预处理的小胶质细胞中诱导IL-1β分泌,从而证实NLRP3是介导SOD1诱导的小胶质细胞IL-1β分泌的关键炎症小体复合物。在TDP-43Q331K ALS小鼠模型中也观察到小胶质NLRP3上调,TDP-43野生型和突变蛋白亦可以NLRP3依赖性的方式激活小胶质炎性小体。从机制上讲,本研究确定了活性氧簇和ATP的生成是SOD1G93A介导的NLRP3激活所需的关键事件。总之,本研究的数据表明ALS小胶质细胞表达NLRP3,而病理ALS蛋白激活小胶质NLRP3炎性小体。因此,NLRP3抑制可能是阻止小胶质细胞神经炎症和ALS疾病进展的潜在治疗方法。 | Vandana Deora John D Lee Eduardo AAlbornoz Luke McAlary Cyril J Jagaraj Avril A B Robertson Julie D Atkin Matthew A Cooper Kate Schroder Justin J Yerbury Richard Gordon Trent MWoodruff 杜一星(编译) | 2020 | 神经损伤与功能重建2020,15,9: | 13 |
| 4 | Radiofrequency ablation for early oesophageal squamous neoplasia:Outcomes form United Kingdom registry显示文摘AIM:To report outcomes on patients undergoing radiofrequency ablation(RFA)for early oesophageal squamous neoplasia from a National Registry.METHODS:A Prospective cohort study from 8 tertiary referral centres in the United Kingdom.Patients with squamous high grade dysplasia(HGD)and early squamous cell carcinoma(ESCC)confined to the mucosa were treated.Visible lesions were removed by endoscopic mucosal resection(EMR)before RFA.Following initial RFA treatment,patients were followed up 3monthly.Residual flat dysplasia was treated with RFA until complete reversal dysplasia(CR-D)was achieved or progression to invasive Squamous cell cancer defined as infiltration into the submucosa layer or beyond.The main outcome measures were CR-D at 12 mo from start of treatment,long term durability,progression to cancer and adverse events.RESULTS:Twenty patients with squamous HGD/ESCC completed treatment protocol.Five patients(25%)had EMR before starting RFA treatment.CR-D was 50%at12 mo with a median of 1 RFA treatment,mean 1.5(range 1-3).Two further patients achieved CR-D with repeat RFA after this time.Eighty per cent with CR-D remain dysplasia free at latest biopsy,with median follow up 24 mo(IQR 17-54).Six of 20 patients(30%)progressed to invasive cancer at 1 year.Four patients(20%)required endoscopic dilatations for symptomatic structuring after treatment.Two of these patients have required serial dilatations thereafter for symptomatic dysphagia with a median of 4 dilatations per patient.The other 2 patients required only a single dilatation to achieve an adequate symptomatic response.One patient developed cancer during follow up after end of treatment protocol.CONCLUSION:The role of RFA in these patients re-mains unclear.In our series 50%patients responded at12 mo.These figures are lower than limited published data. | Rehan J Haidry Mohammed A Butt Jason Dunn Matthew Banks Abhinav Gupta Howard Smart Pradeep Bhandari Lesley Ann Smith Robert Willert Grant Fullarton Morris John Massimo Di Pietro Ian Penman Marco Novelli Laurence B Lovat | 2013 | World Journal of Gastroenterology2013,19,36: | 7 |

| 6 | Effect of weekend admission on geriatric hip fractures显示文摘BACKGROUND The care discrepancy for patients presenting to a hospital on the weekend relative to the work week is well documented.With respect to hip fractures,however,there is no consensus about the presence of a so-called“weekend effect”.This study sought to determine the effects,if any,of weekend admission on care of geriatric hip fractures admitted to a large tertiary care hospital.It was hypothesized that geriatric hip fracture patients admitted on a weekend would have longer times to medical optimization and surgery and increased complication and mortality rates relative to those admitted on a weekday.AIM To determine if weekend admission of geriatric hip fractures is associated with poor outcome measures and surgical delay.METHODS A retrospective chart review of operative geriatric hip fractures treated from 2015-2017 at a large tertiary care hospital was conducted.Two cohorts were compared:patients who arrived at the emergency department on a weekend,and those that arrived at the emergency department on a weekday.Primary outcome measures included mortality rate,complication rate,transfusion rate,and length of stay.Secondary outcome measures included time from emergency department arrival to surgery,time from emergency department arrival to medical optimization,and time from medical optimization to surgery.RESULTS There were no statistically significant differences in length of stay(P=0.2734),transfusion rate(P=0.9325),or mortality rate(P=0.3460)between the weekend and weekday cohorts.Complication rate was higher in patients who presented on a weekend compared to patients who presented on a weekday(13.3%vs 8.3%;P=0.044).Time from emergency department arrival to medical optimization(22.7 h vs 20.0 h;P=0.0015),time from medical optimization to surgery(13.9 h vs 10.8 h;P=0.0172),and time from emergency department arrival to surgery(42.7 h vs 32.5 h;P<0.0001)were all significantly longer in patients who presented to the hospital on a weekend compared to patients who presented to the hospital on a weekday.CONCLUSION This study provided insight into the“weekend effect”for geriatric hip fractures and found that day of presentation has a clinically significant impact on delivered care. | Jordan B Pasternack Matthew L Ciminero Michael Silver Joseph Chang Ronald J Simon Kevin K Kang | 2020 | World Journal of Orthopedics2020,11,9: | 2 |
