OBJECTIVE To assess the feasibility and safety of the minimalistic approach to left atrial appendage occlusion(LAAO) guided by cardiac computed tomography angiography(CCTA).METHODS Ninety consecutive patients who underwent LAAO, with or without CCTA-guided, were matched(1:2). Each step of the LAAO procedure in the computed tomography(CT) guidance group(CT group) was directed by preprocedural CT planning. In the control group, LAAO was performed using the standard method. All patients were followed up for 12 months, and device surveillance was conducted using *** A total of 90 patients were included in the analysis, with 30 patients in the CT group and 60 matched patients in the control group. All patients were successfully implanted with Watchman devices. The mean ages for the CT group and the control group were 70.0 ± 9.4 years and 68.4 ± 11.9 years(P = 0.52), respectively. The procedure duration(45.6 ± 10.7 min vs. 58.8 ± 13.0 min,P < 0.001) and hospital stay(7.5 ± 2.4 day vs. 9.6 ± 2.8 day, P = 0.001) in the CT group was significantly shorter compared to the control group. However, the total radiation dose was higher in the CT group compared to the control group(904.9 ± 348.0 m Gy vs.711.9 ± 211.2 m Gy, P = 0.002). There were no significant differences in periprocedural pericardial effusion(3.3% vs. 6.3%, P = 0.8) between the two groups. The rate of postprocedural adverse events(13.3% vs. 18.3%, P = 0.55) were comparable between both groups at 12 months *** CCTA is capable of detailed LAAO procedure planning. Minimalistic LAAO with preprocedural CCTA planning was feasible and safe, with shortened procedure time and acceptable increased radiation and contras consumption. For patients with contraindications to general anesthesia and/or transesophageal echocardiography, this promising method may be an alternative to conventional LAAO.

《济公活佛》是上海新舞台历史上演出时间最长、票房收益最高的戏,却也是蒙受骂名最多的戏。当时的文化精英认为,新舞台由此从宣传进步思想,堕落为极力讨好观众。新舞台是商业利润与社会责任并重的职业演剧团体,《济公活佛》是其实现通俗教育演剧观念的一次尝试。《济公活佛》的具体做法或有肤浅粗糙之嫌,但其立足传统文化资源、对接现代观众审美的创作理念,依然对当代戏曲有启示意义。

The classic cartoon “Calabash Brothers” describes a story of seven brothers born from a magic gourd uniting to defeat powerful enemies. In order to explore the secret of the magic gourd, several transition metals were used to synthesize metal silicates（CMSi） by planted gourd leaves（GLs） and then the C-MSi materials were used to fabricate supercapacitor electrodes and devices with superior electrochemical performance. By integrating theoretical calculations and experimental results, the supercapacitor electrodes and devices obtained from the combination of transition metals with amorphous carbon exhibit superior electrochemical performance. In detail, in the three-electrode system, the NaOH etched materials（C-MSi） exhibited better electrochemical performance(for instance, as for C-CdSi, 607 F g-1at 0.5 A g-1and the capacitance retention of 98.2% after 10,000cycles) than the unetched ones（i-C-MSi）. Hybrid supercapacitor（HSC） devices also achieve very excellent electrochemical properties. Take C-CdSi//AC as an example, the areal specific capacitance with 691 m F cm-2at 2 mA cm-2, the energy density with 5.04 Wh m-2at the power density of 22.2 W m-2and the cycle stability with 87.3% after 6,000 cycles. This approach is very versatile and was also applied to produce many hierarchically structured metal-silicate materials of other biomass precursors,including roots, vines, flowers, fruits and seeds of the planted gourds. Thus, it is a potential way to prepare transition metal silicates using biomaterials for the enhancement of electrochemical performance and improvement of energy storage and conversion. Also, this paper preliminarily reveals the secret of the magic gourd.

非学位证书(NDC)能够有效记录持有者所掌握的相应技能,以推动人力资源的优化配置。非学位证书作为美国劳动力市场常见的固定工具,其产生背景主要包括人才需求的现实挑战、教育技术的发展繁荣、学习方式的不断革新,实施框架主要包括明确非学位证书的具体类型、建立非学位证书的质量标准、衡量非学位证书的质量水平。为了进一步发挥非学位证书的价值,美国在推进路径中强调注重质量,提升衡量认证的水平;扩大支持,满足学习需求的增加;统一系统,加强信息数据的收集;有效推广,延伸实践应用的空间。然而,美国在非学位证书的实施过程中也面临着一些挑战,如非学位证书的认可度和影响力还有待加强、非学位证书的职业重点和价值受到学界的质疑、非学位证书可能并不会为持有者带来薪酬的显著增长。因此,美国提出要加强对高质量非学位证书的政策支持,保证非学位证书认证过程的公开透明,以及增进非学位证书与劳动力市场的联系。
