| 1 | 颈部动脉夹层分离及其与颈椎推拿疗法的联系:美国心脏协会/美国卒中协会对医疗专业人员的声明显示文摘目的:颈部动脉夹层分离(cervicalarterydissection,CD)是中青年人卒中的最常见病因。本指南旨在对CD诊治的现有证据水平以及其与颈椎推拿疗法(cervical manipulative therapy, CMT)的统计学联系进行回顾。某些类型的CMT是由医疗专业人员对颈椎施加猛烈或轻柔的推力。方法写作组成员由美国心脏协会卒中委员会的科学声明监督委员会以及美国心脏协会的手稿监督委员会任命。各成员负责与其专业领域相关的主题,回顾适当的文献并参考公开发表的临床和流行病学研究、发病率和死亡率报告、临床与公共卫生指南、权威声明、个人文件以及专家意见,对现有证据进行总结并指出目前的知识空白。结果CD患者可表现为单侧头痛、后颈部痛或主要由动脉-动脉栓塞导致的脑或视网膜缺血(短暂性缺血或卒中)、CD脑神经麻痹、眼交感神经麻痹或搏动性耳鸣。CD的诊断依赖于完整的病史、体格检查和针对性的辅助检查。尽管轻微创伤的作用存在争议,但机械压力可造成椎动脉和颈内动脉内膜损伤,进而导致CD。CD患者的残疾程度存在差异,一些患者预后良好,但有些患者则会出现严重神经系统后遗症。目前尚无循证指南可用来指导CD的最佳处理策略。抗血小板和抗凝治疗均被用于局部血栓和继发性栓塞的预防。病例对照研究和其他文献提示CD[尤其是椎动脉夹层分离(vertebral artery dissection, VAD)]与CMT之间存在流行病学联系,但尚不清楚这是由于对先前存在的CD认识不足还是CMT导致的创伤。超声、CT血管造影以及磁共振血管造影都有助于CD的诊断。神经影像学随访首选无创性检查措施,但我们认为任何单一的检查方法都不能作为金标准。结论 CD是中青年患者发生缺血性卒中的重要病因。CD最好发于颈椎上段,可累及颈内动脉或椎动脉。尽管目前的生物力学证据不足以证实CMT 可导致CD,但临床报道提示机械压力在相当一部分CD中起着一定的作用,而且大多数基于人群的对照研究在年轻患者中显示CMT与VAD卒中之间存在联系。尽管对于曾经接受过CMT的患者,CMT相关性CD的发生率尚不完全清楚并且很可能较低,但当有临床症状时,医生应考虑到CD的可能性,并且在进行颈椎推拿前告知患者CD与CMT之间的统计学联系。 | José Biller Ralph L.

| 2 | Temporal-spatial subspaces modern combination method for 2D-DOA estimation in MIMO radar显示文摘A 2D-direction of arrival estimation(DOAE) for multiinput and multi-output(MIMO) radar using improved multiple temporal-spatial subspaces in estimating signal parameters via rotational invariance techniques method(TS-ESPRIT) is introduced. In order to realize the improved TS-ESPRIT, the proposed algorithm divides the planar array into multiple uniform sub-planar arrays with common reference point to get a unified phase shifts measurement point for all sub-arrays. The TS-ESPRIT is applied to each sub-array separately, and in the same time with the others to realize the parallelly temporal and spatial processing, so that it reduces the non-linearity effect of model and decreases the computational time. Then, the time difference of arrival(TDOA)technique is applied to combine the multiple sub-arrays in order to form the improved TS-ESPRIT. It is found that the proposed method achieves high accuracy at a low signal to noise ratio(SNR)with low computational complexity, leading to enhancement of the estimators performance. | Youssef Fayad Caiyun Wang Qunsheng Cao | 2017 | Journal of Systems Engineering and Electronics2017，28，4： | 7 |

| 5 | Reproducibility of thrombus volume quantification in multicenter computed tomography pulmonary angiography studies显示文摘AIM To evaluate reproducibility of pulmonary embolism(PE) clot volume quantification using computed tomography pulmonary angiogram(CTPA) in a multicenter setting.METHODS This study was performed using anonymized data in conformance with HIPAA and IRB Regulations(March 2015-November 2016). Anonymized CTPA data was acquired from 23 scanners from 18 imaging centers using each site's standard PE protocol. Two independent analysts measured PE volumes using a semi-automated region-growing algorithm on an FDA-approved image analysis platform. Total thrombus volume(TTV) was calculated per patient as the primary endpoint. Secondary endpoints were individual thrombus volume(ITV), Qanadli score and modified Qanadli score per patient. Inter-and intra-observer reproducibility were assessed using intra-class correlation coefficient(ICC) and BlandAltman analysis. RESULTS Analyst 1 found 72 emboli in the 23 patients with a mean number of emboli of 3.13 per patient with a range of 0-11 emboli per patient. The clot volumes ranged from 0.0041-47.34 cm3(mean +/-SD, 5.93 +/-10.15 cm3). On the second read, analyst 1 found the same number and distribution of emboli with a range of volumes for read 2 from 0.0041 – 45.52 cm3(mean +/-SD, 5.42 +/-9.53 cm3). Analyst 2 found 73 emboli in the 23 patients with a mean number of emboli of 3.17 per patient with a range of 0-11 emboli per patient. The clot volumes ranged from 0.00459-46.29 cm3(mean +/-SD, 5.91 +/-10.06 cm3). Inter-and intraobserver variability measurements indicated excellent reproducibility of the semi-automated method for quantifying PE volume burden. ICC for all endpoints was greater than 0.95 for inter-and intra-observer analysis. Bland-Altman analysis indicated no significant biases.CONCLUSION Semi-automated region growing algorithm for quantifying PE is reproducible using data from multiple scanners and is a suitable method for image analysis in multicenter clinical trials. | Audrey E Kaufman Alison N Pruzan Ching Hsu Sarayu Ramachandran Adam Jacobi Indravadan Patel Lee Schwocho Michele F Mercuri Zahi A Fayad Venkatesh Mani | 2018 | World Journal of Radiology2018，10，10： | 3 |
| 6 | Effect of varying computed tomography acquisition and reconstruction parameters on semi-automated clot volume quantification显示文摘AIM To examine effects of computed tomography(CT)image acquisition/reconstruction parameters on clot volume quantification in vitro for research method validation purposes.METHODS This study was performed in conformance with HIPAA and IRB Regulations(March 2015-November 2016).A ten blood clot phantom was designed and scanned on a dual-energy CT scanner(SOMATOM Force,Siemens Healthcare Gm BH,Erlangen,Germany)with varying pitch,iterative reconstruction,energy level and slicethickness.A range of clot and tube sizes were used in an attempt to replicate in vivo emboli found within central and segmental branches of the pulmonary arteries in patients with pulmonary emboli.Clot volume was the measured parameter and was analyzed by a single image analyst using a semi-automated region growing algorithm implemented in the FDA-approved Siemens syngo.via image analysis platform.Mixed model analysis was performed on the data.RESULTS On the acquisition side,the continuous factor of energy showed no statistically significant effect on absolute clot volume quantification(P=0.9898).On the other hand,when considering the fixed factor of pitch,there were statistically significant differences in clot volume quantification(P<0.0001).On the reconstruction side,with the continuous factor of reconstruction slice thickness no statistically significant effect on absolute clot volume quantification was demonstrated(P=0.4500).Also on the reconstruction side,with the fixed factor of using iterative reconstructions there was also no statistically significant effect on absolute clot volume quantification(P=0.3011).In addition,there was excellent R^2 correlation between the scale-measured mass of the clots both with respect to the CT measured volumes and with respect to volumes measure by the water displacement method.CONCLUSION Aside from varying pitch,changing CT acquisition parameters and using iterative reconstructions had no significant impact on clot volume quantification with a semi-automated region growing algorithm. | Audrey E Kaufman Alison N Pruzan Ching Hsu Sarayu Ramachandran Adam Jacobi Zahi A Fayad Venkatesh Mani | 2018 | World Journal of Radiology2018，10，3： | 3 |
| 7 | Mitochondrial complex Ⅰ as a therapeutic target for Alzheimer’s disease显示文摘Alzheimer’s disease(AD),the most prominent form of dementia in the elderly,has no cure.Strategies focused on the reduction of amyloid beta or hyperphosphorylated Tau protein have largely failed in clinical trials.Novel therapeutic targets and strategies are urgently needed.Emerging data suggest that in response to environmental stress,mitochondria initiate an integrated stress response(ISR)shown to be beneficial for healthy aging and neuroprotection.Here,we review data that implicate mitochondrial electron transport complexes involved in oxidative phosphorylation as a hub for small molecule-targeted therapeutics that could induce beneficial mitochondrial ISR.Specifically,partial inhibition of mitochondrial complex I has been exploited as a novel strategy for multiple human conditions,including AD,with several small molecules being tested in clinical trials.We discuss current understanding of the molecular mechanisms involved in this counterintuitive approach.Since this strategy has also been shown to enhance health and life span,the development of safe and efficacious complex Ⅰ inhibitors could promote healthy aging,delaying the onset of age-related neurodegenerative diseases. | Eugenia Trushina Sergey Trushin Md Fayad Hasan | 2022 | Acta Pharmaceutica Sinica B2022，12，2： | 3 |

| 9 | Atherosclerosis imaging using 3D black blood TSE SPACE vs 2D TSE显示文摘AIM: To compare 3D Black Blood turbo spin echo(TSE)sampling perfection with application-optimized contrast using different flip angle evolution(SPACE) vs 2D TSE in evaluating atherosclerotic plaques in multiple vascular territories. METHODS: The carotid, aortic, and femoral arterial walls of 16 patients at risk for cardiovascular or atherosclerotic disease were studied using both 3D black blood magnetic resonance imaging SPACE and conventional 2D multi-contrast TSE sequences using a consolidated imaging approach in the same imaging session. Qualitative and quantitative analyses were performed on the images. Agreement of morphometric measurements between the two imaging sequences was assessed using a two-sample t-test, calculation of the intra-class correlation coefficient and by the method of linear regression and Bland-Altman analyses. RESULTS: No statistically significant qualitative differences were found between the 3D SPACE and 2D TSE techniques for images of the carotids and aorta. For images of the femoral arteries, however, there were statistically significant differences in all four qualitative scores between the two techniques. Using the current approach, 3D SPACE is suboptimal for femoral imaging. However, this may be due to coils not being optimized for femoral imaging. Quantitatively, in our study, higher mean total vessel area measurements for the 3D SPACE technique across all three vascular beds were observed. No significant differences in lumen area for both the right and left carotids were observed between the two techniques. Overall, a significant-correlation existed between measures obtained between the two approaches. CONCLUSION: Qualitative and quantitative measurements between 3D SPACE and 2D TSE techniques are comparable. 3D-SPACE may be a feasible approach in the evaluation of cardiovascular patients. | Stephanie K Wong Motunrayo Mobolaji-Iawal Leron Arama Joy Cambe Sylvia Biso Nadia Alie Zahi A Fayad Venkatesh Mani | 2014 | World Journal of Radiology2014，6，5： | 3 |

| 12 | Imaging plaque inflammation in asymptomatic cocaine addicted individuals with simultaneous positron emission tomography/magnetic resonance imaging显示文摘BACKGROUND Chronic cocaine use is associated with stroke, coronary artery disease and myocardial infarction, resulting in severe impairments or sudden mortality. In the absence of clear cardiovascular symptoms, individuals with cocaine use disorder (iCUD) seeking addiction treatment receive mostly psychotherapy and psychiatric pharmacotherapy, with no attention to vascular disease (i.e., atherosclerosis). Little is known about the pre-clinical signs of cardiovascular risk in iCUD and early signs of vascular disease are undetected in this underserved population. AIM To assess inflammation, plaque burden and plaque composition in iCUD aiming to detect markers of atherosclerosis and vascular disease. METHODS The bilateral carotid arteries were imaged with positron emission tomography/magnetic resonance imaging (PET/MRI) in iCUD asymptomatic for cardiovascular disease, healthy controls, and individuals with cardiovascular risk. PET with 18F-fluorodeoxyglucose (18F-FDG) evaluated vascular inflammation and 3-D dark-blood MRI assessed plaque burden including wall area and thickness. Drug use and severity of addiction were assessed with standardized instruments. RESULTS The majority of iCUD and controls had carotid FDG-PET signal greater than 1.6 but lower than 3, indicating the presence of mild to moderate inflammation. However, the MRI measure of wall structure was thicker in iCUD as compared to the controls and cardiovascular risk group, indicating greater carotid plaque burden. iCUD had larger wall area as compared to the healthy controls but not as compared to the cardiovascular risk group, indicating structural wall similarities between the non-control study groups. In iCUD, wall area correlated with greater cocaine withdrawal and craving. CONCLUSION These preliminary results show markers of carotid artery disease burden in cardiovascular disease-asymptomatic iCUD. Broader trials are warranted to develop protocols for early detection of cardiovascular risk and preventive intervention in iCUD. | Keren Bachi Venkatesh Mani Audrey E Kaufman Nadia Alie Rita Z Goldstein Zahi A Fayad Nelly Alia-Klein | 2019 | World Journal of Radiology2019，11，5： | 2 |
| 13 | Review of radiographic findings in COVID-19显示文摘The purpose of this study is to review the published literature for the range ofradiographic findings present in patients suffering from coronavirus disease 2019infection. This novel corona virus is currently the cause of a worldwide pandemic.Pulmonary symptoms and signs dominate the clinical picture and radiologists arecalled upon to evaluate chest radiographs (CXR) and computed tomography (CT)images to assess for infiltrates and to define their extent, distribution andprogression. Multiple studies attempt to characterize the disease course bylooking at the timing of imaging relative to the onset of symptoms. In general,plain CXR show bilateral disease with a tendency toward the lung periphery andhave an appearance most consistent with viral pneumonia. Chest CT images aremost notable for showing bilateral and peripheral ground glass and consolidatedopacities and are marked by an absence of concomitant pulmonary nodules,cavitation, adenopathy and pleural effusions. Published literature mentioningorgan systems aside from pulmonary manifestations are relatively less common,yet present and are addressed in this review. Similarly, publications focusing onimaging modalities aside from CXR and chest CT are sparse in this evolving crisisand are likewise addressed in this review. The role of imaging is examined as it iscurrently being debated in the medical community, which is not at all surprisingconsidering the highly infectious nature of Severe Acute Respiratory Syndromecoronavirus 2. | Audrey E Kaufman Sonum Naidu Sarayu Ramachandran Dalia S Kaufman Zahi A Fayad Venkatesh Mani | 2020 | World Journal of Radiology2020，12，8： | 2 |
