1应用64层CT对心肌灌注缺损、局部室壁运动及左室功能的综合评估显示文摘目的评估64层CT评价心肌灌注缺损(PD),局部室壁运动(RWM)和左室(Lv)功能的准确性。方法所有心肌梗死(MI)病人签署知情同意书。本研究经机构审查委员会批准并依从HIPAA法案。102例病人(34例近期患急性MI,68例未患MI)接受了心脏多层CT检查。分析心脏多层CT影像以评估心肌PD、RWM异常和LV功能。多层CT获得的LV总体功能及RWM与经胸超声心动图(TTE)对照。PD由多层CT检出,并评价其与心脏生化指标及SPECT心肌灌注成像的相关性。多层CT诊断急性MI的根据,是有与RWM异常相匹配的PD并与临床评估对照。结果多层CT获得的总体心功能(r=0.68)和RWM(K=0,79)与TIE相关性良好。R.C.

2Preemptive mechanical ventilation can block progressive acute lung injury显示文摘Mortality from acute respiratory distress syndrome(ARDS) remains unacceptable, approaching 45% in certain high-risk patient populations. Treating fulminant ARDS is currently relegated to supportive care measures only. Thus, the best treatment for ARDS may lie with preventing this syndrome from ever occurring. Clinical studies were examined to determine why ARDS has remained resistant to treatment over the past several decades. In addition, both basic science and clinical studies were examined to determine the impact that early, protective mechanical ventilation may have on preventing the development of ARDS in at-risk patients. Fulminant ARDS is highly resistant to both pharmacologic treatment and methods of mechanical ventilation. However, ARDS is a progressive disease with an early treatment window that can be exploited. In particular, protective mechanical ventilation initiated before the onset of lung injury can prevent the progression to ARDS. Airway pressure release ventilation(APRV) is a novel mechanical ventilation strategy for delivering a protective breath that has been shown to block progressive acute lung injury(ALI) and prevent ALI from progressing to ARDS. ARDS mortality currently remains as high as 45% in some studies. As ARDS is a progressive disease, the key to treatment lies with preventing the disease from ever occurring while it remains subclinical. Early protective mechanical ventilation with APRV appears to offer substantial benefit in this regard and may be the prophylactic treatment of choice for preventing ARDS.Benjamin Sadowitz Sumeet Jain Michaela Kollisch-Singule Joshua Satalin Penny Andrews Nader Habashi Louis A Gatto Gary Nieman 2016World Journal of Critical Care Medicine2016,5,1:9
3Design and Implementation of a TDD-Based 128-Antenna Massive MIMO Prototype System显示文摘Owing to the dramatic mobile IP growth,the emerging Internet of Things,and cloud-based applications,wireless networking is witnessing a paradigm shift.By fully exploiting spatial degrees of freedom,massive multiple-input-multiple-output(MIMO) systems promise significant gains in data rates and link reliability.Although the research community has recognized the theoretical benefits of these systems,building the hardware of such complex systems is a challenge in practice.This paper presents a time division duplex(TDD)-based 128-antenna massive MIMO prototype system from theory to reality.First,an analytical signal model is provided to facilitate the setup of a feasible massive MIMO prototype system.Second,a link-level simulation consistent with practical TDDbased massive MIMO systems is conducted to guide and validate the massive MIMO system design.We design and implement the TDDbased 128-antenna massive MIMO prototype system with the guidelines obtained from the link-level simulation.Uplink real-time video transmission and downlink data transmission under the configuration of multiple single-antenna users are achieved.Comparisons withstate-of-the-art prototypes demonstrate the advantages of the proposed system in terms of antenna number,bandwidth,latency,and throughput.The proposed system is also equipped with scalability,which makes the system applicable to a wide range of massive scenarios.Xi Yang Wenjun Lu Ning Wang Karl Nieman Chao-Kai Wen Chuan Zhang Shi Jin Xiaomin Mu Ian Wong Yongming Huang Xiaohu You 2017China Communications2017,14,12:3
