  • 简介:摘要目的比较MRI和US在子宫腺肌病中诊断价值,探讨两种方法对子宫腺肌病(AD)应用价值。方法对我院妇科门诊收集的82例疑似AD患者均行MRI和US检查。观察US和MRI表现,术后行病理学检查作为对比。结果82例疑似AD患者病理组织学检查,确诊子宫腺肌病38例,子宫肌瘤42例,子宫血管瘤2例。MRI与病理对照后,确诊子宫腺肌病35例,误诊1例,漏诊2例,诊断符合率92.1%,误诊率2.6%,漏诊率5.3%;US与病理对照后,确诊子宫腺肌病31例,误诊4例,漏诊7例,诊断符合率81.6%,误诊率10.5%,漏诊率18.4%,二者对比差异有统计学意义(P<0.05)。结论MRI诊断子宫腺肌病敏感性、特异性、准确性明显优于US,且对子宫结构显示更为清晰,还可进行定性、定位诊断,临床实用价值更突出。

  • 简介:AbstractAs the entire world is under the grip of the coronavirus disease 2019 (COVID-19), and as many are eagerly trying to explain the origins of the virus and cause of the pandemic, it is imperative to place more attention on related potential biosafety risks. Biology and biotechnology have changed dramatically during the last ten years or so. Their reliance on digitization, automation, and their cyber-overlaps have created new vulnerabilities for unintended consequences and potentials for intended exploitation that are mostly under-appreciated. This study summarizes and elaborates on these new cyberbiosecurity challenges, (1) in terms of comprehending the evolving threat landscape and determining new risk potentials, (2) in developing adequate safeguarding measures, their validation and implementation, and (3) specific critical risks and consequences, many of them unique to the life-sciences. Drawing other's expertise and my previous work, this article reviews and critically interprets our current bio-economy situation. The goal is not to attribute causative aspects of past biosafety or biosecurity events, but to highlight the fact that the bioeconomy harbors unique features that have to be more critically assessed for their potential to unintentionally cause harm to human health or environment, or to be re-tasked with an intention to cause harm. It is concluded with recommendations that will need to be considered to help ensure converging and emerging biorisk challenges, in order to minimize vulnerabilities to the life-science enterprise, public health, and national security.

  • 简介:AMD平台的主板其实都不容易,因为CPU的价格太白菜,所以主板也不能太贵。因为CPU能开核,所以主板必须得具备开核功能。因为开核需要良好的稳定性作支撑,所以设计用料都得是一流。技嘉最新推出的MA770T—US3正好符合上述标准。它的官方报价为649元,主流用户完全能够接受。
