Purpose:The aim of the study was to examine the influence of the surgical approach for robot-assisted laparoscopic prostatectomy(RALP)on long-term urinary continence status in the era of self-reported functional status measures using the Expanded Prostate Can-cer Index Composite 26.Materials and methods:This is a prospective evaluation of 232 patients undergoing RALP between September,2019 and September,*** continence status and postoperative incontinence(pad usage)were evaluated 12 months after RALP using Expanded Prostate Cancer Index Composite 26 *** were categorized according to their surgical approach and outcome into the following groups:successful nerve sparing(NS),primarily without nerve sparing(***),and no nerve sparing by secondary resection(NNS by SR).The median levels of their questionnaire outcomes were evaluated and compared using the Wilcoxon rank sum test with continuity correction.Results:Urinary continence status 12 months after RALP differed significantly between the NS and ***(p=0.0071)and the NS and NNS by SR(p=0.0076)*** was no significant difference between the *** and NNS by SR(p=0.53)*** usage 12 months after RALP had no significant difference with regard to SR of the neurovascular bundle(p=0.14).Conclusions:Patient-reported outcomes of long-term urinary continence status seem to show no difference in postoperative conti-nence,regardless of whether a non-nerve-sparing result was planned or reached through ***,preservation of neurovascular bundle seems to lead to better long-term continence rates.

Pathologic Q Waves and Prolonged QTc Time in Preoperative ECG Are Predictive for Perioperative Cardiovascular Events

Aims: The value of ECG in the perioperative risk stratification under modern treatment options is uncertain. The main objective of the present analysis was to determine the usefulness of a pre-operative ECG derivation for evaluating the risk of perioperative morbidity and mortality. Methods: We performed a secondary analysis of the prospective, international, multicenter, observational “No-Risk” Study (N-terminal B-type natriuretic peptide [NT-proBNP] for the assessment of the perioperative cardiac risk after major noncardiac surgery) to determine the prognostic value of 12-lead ECG. Inclusion criteria were age >55 years and at least one of the following cardiovascular risk factors: arterial hypertension, diabetes mellitus, dyslipidemia, active smoking, and family history positive for coronary heart disease. The combined primary endpoint included total mortality, acute myocardial infarction (NSTEMI and STEMI), cardiopulmonary resuscitation, heart failure, and asystole or ventricular fibrillation during hospitalization. ECGs from 616 patients enrolled from 2006 to 2009 prior to noncardiac surgery in the No-Risk Study were analyzed. Results: The mean age was 67.6 (±8.1) years;300 (48.7%) patients were male. Fourteen (2.3%) patients suffered from the combined primary endpoint while in the hospital. In Kaplan-Meier analyses, a pathologic Q wave and QTc > 500 ms were significantly related to the incidence of the primary endpoint (p p = 0.042, respectively), whereas other ECG parameters such as LBBB, RBBB, PQ interval, QRS interval, and others were not related to worse in-hospital outcome. Conclusion: The 12-lead ECG is still an important diagnostic tool for perioperative risk assessment of cardiovascular events in noncardiac surgery in patients at risk.

Zinc Fingers, TAL Effectors, or Cas9-Based DNA Binding Proteins： What＇s Best for Targeting Desired Genome Loci？

引用

Molecular Plant 2013年第5期6卷 1384-1387页

作者： Annett strauβ Thomas Lahaye Faculty of Biology Institute of Genetics Ludwig-Maximilians-University Munich Grolβhaderner Straβe 2-4 D-82152 Martinsried Germany

ZINC FINGER- AND TAL EFFECTOR- BASED DNA BINDING PROTEINSProgrammable DNA binding proteins （PDPs） that selectively bind user-defined nucleotide sequences can navigate protein domains to any desired target within the genome. Different functional domains can be fused to PDPs to achieve （1） acti- vation or repression of transcription, （2） nicking or cleavage of DNA, or （3） modification or removal of epigenetic marks at the targeted genome spot. Given their broad applicabil- ity, the development of highly specific, easy-to-use PDPs has been a holy grail of biotechnology since the determination of the 3-D structure of zinc fingers （ZFs） bound to DNA in 1991 （Pavletich and Pabo, 1991）. This structure suggested that tandemly arranged ZFs act as functionally independ- ent modules with each finger binding three bases. However, the combination of fingers with experimentally defined base specificities into arrays revealed that ZFs are not function- ally independent. Instead, they were found to behave in a context-dependent, and often unpredictable fashion requir- ing iterative cycles of selection to get ZF arrays with desired specificity （Joung and Sander, 2013）.

设计除应符合焊接和检验要求外,在使用条件苛刻、安全和检验要求很严的大型复杂焊接部件的设计中,日益显得重要的是,要求满足焊接过程的“合理设计”。尽管不少科学研究成果使人们增加了焊接方法或焊丝的变动对焊接材料性能影响方面的知识,但在实际上,这些知识的推广和应用往往未被重视。焊接新技术和新方法的发展和系统应用将有助于简化设计和制造,改善质量,同时使目前尚不能制造或用传统的设备来制造时成本相当高的部件有可能制造。为此,本文主要介绍反应堆及压力容器工程领域内有关焊接的实践经验,并讨论在厚壁部件焊接的发展趋势。
