Purpose: Improvements to photoselective vaporization of the prostate (PVP) have been made over time, particularly with the introduction of higher power systems. Few studies however have compared the performance of these systems to their predecessors. The purpose of this study was to compare the clinical and perioperative outcomes of 80 W vs. 120 W PVP. Materials and Methods: A series of 267 and 209 consecutive patients underwent 80 W and 120 W PVP, respectively, from september 2001 to May 2009 at Weill Cornell Medical College (GreenLightTM laser system, American Medical systems, Inc., Minnetonka, MN). Data were collected on patient demographics, International Prostate symptom score (IPss), prostate-specific antigen (PsA), and perioperative parameters. Maximum flow rate (Qmax), postvoid residual (PVR), and transrectal ultrasound prostate volume were recorded. statistical analyses were carried out utilizing the shapiro-Wilk, Mann-Whitney, Wilcoxon and unpaired t tests (sPss 15.0, sPss Inc., Chicago, IL, UsA). Results: Baseline parameters were similar between the two groups except for greater median age (72.8 vs. 69.2 years, p = 0.01) and lower median PsA (2.0 vs. 3.3, p = 0.01) in the 80 W group. Median laser time was longer in the 80W group (85 vs. 51 minutes, p 0.001) with a higher median energy utilized (253 vs. 210 kJ, p = 0.001). Final IPss, Qmax, PVR, and PsA were equivalent between the two groups. Conclusions: In our series, PVP was safe and effective. Durable and similar improvements in symptoms and objective parameters were achieved in patients with both 80 W and 120 W laser systems. PVP with the 120 W system, however, provided faster and more efficient vaporization compared to the 80 W system.

Objective:In this study, the feasibility to evaluate the global myocardial activation and repolarization sequence using the electroanatomical mapping system and MAP recording technique via the modified platinum catheter was explored in swine. Methods:Ten healthy pigs (50-55 kg) were anaesthetized with pentobarbital and catamine, intubated and ventilated. Four vascular accesses were obtained. A modified small tip ablation catheter (Navi-star, Biosense Webster), the end surface of tip electrode was 0.81 mm 2 and 1 mm in diameter, was used for MAP recording. The MAP electrograms were recorded between the tip (exploring electrode) and the ring electrode proximal to the tip (indifferent electrode). The catheter was intentionally positioned perpendicular to endocardium with slight contact pressure to allow MAP recording with a satisfactory amplitude and morphology. All MAP recordings were performed during sinus ***:The MAP recordings were obtained from both right atrium and left ventricle in 9 pigs, while the right ventricle was mapped during the same procedure in 2. The MAP electrograms were recorded from both right and left atrium via a patent foramen ovale in 1 pig. Totally, the right atrium was mapped in all the 10 pigs, right ventricle in 2, left atrium in 1 and left ventricle in 9. The MAP electrograms were recorded from 733 sites of right atrium, 179 of right ventricle, 63 of left atrium and 517 of left ventricle. There were 62% of right and 54% left atrial MAPamp satisfied the earlier defined criteria of acceptable MAP, i.e., the MAPamp ≥ 3 mV in atrium, while 32% of right and 38% of left ventricular MAPamp were ≥ 10 mV. The mean MAPamp was 5.7±3.1 mV in right atrium, 12.4±2.5 mV in right ventricle, 4.5±1.9 mV in left atrium and 13.8±4 mV in left ventricle. The local activation was more distinctly and easily defined using MAP recordings with the computer-assisted manual determination, so were the end-of-repolarization points. The global activation and r

目的:分析右室心肌梗死(心梗)对急性下壁心梗临床特征和预后的影响。方法:比较急性单纯性下壁心梗(第一组)和急性下壁心梗合并右室心梗(第二组)两组患者的临床特征和院内病死率。结果:共176例患者符合入选条件,第一组115例,第二组61例。第一组低血压、快速心律失常(包括阵发性室上性心动过速,阵发性心房颤动,频发室性早搏,室性心动过速,心室纤颤等)、缓慢心律失常(包括窦性心动过缓,房室传导阻滞)、心功能不全的发生率和院内病死率显著低于第二组(P<0.05)。静脉溶栓、急诊PTCA和未行再灌注治疗的院内病死率在第一组的分别为3.23％,3.33％和29.17％,在第二组分别为9.z5％,13.04％和82.35％。结论:当急性下壁心梗合并右室心梗时,患者的临床表现更为严重,院内病死率增高。积极行溶栓或急诊PTCA治疗,可显著降低其院内病死率。
