采用恒电流电共沉积技术,以SnO_2导电玻璃为基片制备了Gabs薄膜。通过观察实验过程和对比各次实验结果,研究了在电解液中加入络合剂EDTA对成膜质量的影响以及实验过程中的烧焦现象和电火花现象。采用扫描电子显微镜(SEM)和X射线衍射(XRD)仪测试表明,沉积膜为GaAs多晶薄膜,加入络合剂EDTA明显改善了薄膜的表面形貌,提高了沉积膜的厚度,降低了各次实验数值分散性,而且使沉积膜中As与Ga的化学计量比更接近1:1。选择适当的沉积工艺可以避免烧焦和电火花的出现。

目的:探讨术前血清护骨素(osteoprotegerin,OPG)、可溶性核因子κB受体活化因子配体(soluble receptor activator of nuclear factor-κB ligand,sRANKL)水平和sRANKL/OPG比值能否预测瓣膜病合并房颤患者行改良迷宫术后房颤复发的风险。方法:选取瓣膜病合并持续性房颤行改良迷宫术患者共114例,以术后3个月内房颤是否复发分为房颤组和窦性心律组。术前采集患者的桡动脉血,采用ELISA法检测血清中OPG和sRANKL的水平。结果:(1)房颤组术前血清中OPG、sRANKL水平和sRANKL/OPG比值均显著高于窦性心律组;(2)多因素Logistic回归分析结果显示,除左房内径外,术前血清sRANKL水平和sRANKL/OPG比值也能独立预测改良迷宫术后房颤的复发;(3)ROC曲线评价血清sRANKL水平与sRANKL/OPG比值用来预测改良迷宫术后房颤复发的最佳截断点分别为6.75 pmol/L和0.87,最佳截断点上血清sRANKL(>6.75 pmol/L)预测术后房颤复发的敏感性、特异性和正确率分别为89.7%、89.3%、89.5%,而sRANKL/OPG比值(>0.87)分别为92.3%、98.7%、92.1%。结论:术前血清sRANKL水平和sRANKL/OPG比值能独立预测瓣膜病合并房颤患者行改良迷宫术后房颤的复发,因此可用来筛选术中是否适合行改良迷宫手术的患者,或用作术前术后尽早干预的靶点以减少房颤的复发。

In this paper,porous partially fluorinated graphene(PFG)for supercapacitors(SCs)was fabricated by a mild and secure one-pot hydrothermal method utilizing weakly coordinating anion BF_(4)^(-) as the fluorine *** hydrolysis rate of sodium fluoroborate was adjusted by controlling the reaction temperature and PFG containing semi-ionic C-F bonds was obtained,where the content of semi-ionic C-F bonds in PFG can be easily *** final experimental results show that the incorporation of fluorine not only modulates the electrochemical properties of the material,but also creates abundant *** assembled in a symmetric supercapacitor,the PFG shows a high specific capacitance of 269.7 F g^(-1) at 1 A g^(-1) and a superior rate capability with 89.3%capacitance retained,as the current density is increased from 1 A g^(-1)even to 20 A g^(-1).Furthermore,the resultant energy density for PFG is 9.4 Wh kg^(-1) at a power density of 250.0 W kg^(-1)(1 A g^(-1)).All these results confirm that as-prepared partially fluorinated graphene is appropriate for the application in SCs and mass production.

We report a case of myxoma with multiple recurrences in both the atrium and ventricle in a 26-year-old woman five years after the surgical removal of left atrial myxoma, Her 52-year-old mother had a similar medical history. To our knowledge, this was the first familial case who suffered multifocal cardiac myxoma recurrences without any sign of the myxoma complex. Based on our understanding of the mechanism of recurrence, the approaches to prevent the recurrence, and markers to predict recurrence, we propose that multifocal recurrences, as reported herein, may result from a combination of familial predisposition and multifocal onset. The hi-atrial surgical approach and transesophageal echocardiography are preferred for patients with recurrent cardiac myxomas, especially for those with multiple recurrences and familial myxoma. Immunological and genetic screenings may help to identify family members at risk for developing this disease.
