| 1 | 基于循证医学的产前超声检查对脐带螺旋结构的评价及其误区显示文摘脐带螺旋结构在国内文献中,通常描述为脐带螺旋、扭转、螺旋状扭转等,尚无统一定义。产前要明确鉴别脐带扭转和自身螺旋非常困难。目前,产前超声观察脐带螺旋结构的指标、诊断标准不统一,脐带螺旋结构异常对脐血流的影响不明确,产前超声诊断脐带螺旋结构异常与不良妊娠结局的关系缺乏严谨的循证医学证据。将未经充分论证的观察指标用于临床,会给妇产科医师带来困扰,也可能会引起孕妇不必要的焦虑、医源性早产及医疗纠纷。本文通过回顾性分析国内、外文献,解析目前产前超声评价脐带螺旋结构的疑问和误区。 | 李胜利 廖伊梅 Guoyang Luo | 2019 | 中华妇产科杂志2019，54，2： | 12 |
| 2 | All-in-one photoelectric logic gates by Dember photodetectors显示文摘Photoelectric logic gates(PELGs) are the key component in integrated electronics due to their abilities of signal conversion and logic operations. However, traditional PELGs with fixed architectures can realize only very limited logic functions with relatively low on–off ratios. We present a self-driving polarized photodetector driven by the Dember effect, which yields ambipolar photocurrents through photonic modulation by a nested grating. The ambipolar response is realized by exciting the whispering-gallery mode and localized surface plasmon resonances,which leads to reverse spatial carrier generation and therefore the contrary photocurrent assisted by the Dember effect. We further design a full-functional PELG, which enables all five basic logic functions(“AND”, “OR”,“NOT”, “NAND”, and “NOR”) simultaneously in a single device by using one source and one photodetector only. Such an all-in-one PELG exhibits a strong robustness against structure size, incident wavelength, light power, and half-wave plate modulation, paving a way to the realization of ultracompact high-performance PELGs. | GUOYANG CAO CHANGLEI WANG YU LUO XIAOFENG LI | 2023 | Photonics Research2023，11，7： | 0 |
| 3 | New Year’s Greetings显示文摘The year 2020 brought significant challenges to all of us in our professional and personal lives,as we have had to face the ravages and disruptions of the COVID-19 pandemic.Despite these challenges,M aternal-Fetal M edicine had a very productive year thanks to our authors,reviewers,leadership,and members of the journal’s Editorial Board.Many papers were well received by our readers and cited in subsequent publications in top scientific journals. | Huixia Yang Guoyang Luo | 2021 | Maternal-Fetal Medicine2021，3，1： | 0 |
