若想享受1920×1080的高清影像，又想体验Dolby True HD、DTS—HD MA（Master Audio）或者拥有巨大信息量的无损线性音频（Linear Pulse Code Modulation），相信选择观看BD绝对是最快捷、最方便的途径了。不过，有一部分人并不是这样认为的，究其原因就是因为目前有不少的BD作品都没有带有我们熟悉的中文。由于国内的BD市场起步较慢，早期所推出的带有中文字幕的BD都是由国外公司所推出，而华语的BD只是九牛一毛。

磁电偶极子天线有着宽带、对称方向图、低后瓣和稳定增益等优越性能,在诸如基站天线设计等应用场合颇受青睐.另一方面,随着通信系统朝着大容量、高可靠性和智能化等方向发展,可重构天线因其可重配置的天线特性受到广泛关注.该文总结回顾了极化可重构磁电偶极子天线的研究进展,着重介绍了一种高天线效率、三种极化选择和一种单端口、四种极化选择的磁电偶极子天线的设计和分析.相对于传统的基于微带天线的极化可重构设计,提出的基于磁电偶极子天线的极化可重构天线,具有交叠带宽宽,方向图对称,增益稳定等优点;并且通过采用如低损耗的可重构微扰结构和交叉阵子结构馈电等技术,可以实现较高的天线效率或是更少的馈电端口和不复杂的直流偏压电路.其在未来高度集成化、绿色和智能化的无线通信系统中有着一定的应用前景.

This paper describes the design of an endoscopic image-integrated clinical information metwork using Intranet technology. It was developed for electronically managing integrated medical records of patients in a speccialised procedural clinic. Image capturing feature and voice atcivation are incorporated into the system to facilitate real-time operation during clinical procedures. A network prototype has been set up and the results support the feasibility of the proposed approach. It is envisioned that the proposed approach will enable doctors to use clinical information network to achieve intra-networking as

Open Journal of Psychiatry 2022年第2期12卷 157-173页

作者： Hoi Tik Fung kit Ping Loretta Lai Man Hei Matthew luk.Pang Fai Chan Department of Family Medicine and Primary Health Care United Christian Hospital and Tseung Kwan O Hospital Kowloon East Cluster Hospital Authority Hong Kong China

Purpose: Our study aimed to evaluate the psychological impact of COVID-19 pandemic on Chinese patients with common mental disorders in primary care in Hong kong. Method: A cross-sectional study was conducted on 102 Chinese patients with common mental disorders and being followed up in two public integrated mental health clinics in Hong kong from 1st November 2020 to 31st January 2021. Patients would be evaluated about the impact of COVID-19 pandemic on their mood and daily life by using a questionnaire which assessed social distancing effects, financial impact, relationship with family, anxiety and depressive symptoms. The Patient Health Questionnaire-9 (PHQ-9) and General Anxiety Disorder-7 Questionnaire (GAD-7) would also be used to assess patients’ mood symptoms. Factors which were related to COVID-19 pandemic and associated with anxiety or depressive symptoms would be analysed. Results: The mean age of the subjects was 58.0 years and more patients were female (77.5%). There were 84.3% and 72.5% of patients reported their anxiety and depressive symptoms being affected by COVID-19 pandemic respectively. It was found that 17.6% of patients had their income decreased or were unemployed. About one-third (30.4%) of patients indicated that their relationship with their family was worsened while 8.8% was improved. Social distancing was significantly associated with anxiety (p = 0.006) and depressive symptoms (p 0.001) in patients with common mental disorders. Conclusion: There was considerably more psychological impact including an increase in anxiety and depressive symptoms due to COVID-19 pandemic in Chinese patients with existing common mental disorders in primary care. Primary care physicians should raise their awareness of the psychological impact of COVID-19 pandemic on their patients. Our findings shed light on mental health care planning and preventive measures during the COVID-19 pandemic and potential subsequent pandemics.

目的:探讨磁共振弥散张量成像(diffusion tensor imaging,DTI)在预测脊髓型颈椎病(cervical spondylotic myelopathy,CSM)患者术后神经功能恢复中的作用。方法:前瞻性分析50例行手术治疗的CSM患者的临床资料,患者年龄43~86岁(64.3±11.2岁)。以19例年龄50~62岁(54.6±4.2岁)的健康志愿者作为对照组。应用3.0T磁共振DTI成像序列,观察患者术前各神经纤维束感兴趣区(包括整个颈髓、颈髓前束、侧束及后束)中的各向异性分数(fractional anisotropy,FA)、平均弥散率(mean diffusivity,MD)、轴向弥散系数(axial diffusivity,AD)及径向弥散系数(radial diffusivity,RD),将患者按术后神经功能日本骨科协会(Japanese Orthopedic Association,JOA)评分改善率(recovery rate,RR)分为3组:优良疗效组(RR>0.7)、中等疗效组(RR 0.4~0.7)和一般疗效组(RR0.05)。除优良疗效组整个颈髓的FA值外,3个患者组的FA、MD和RD值与对照组比较均存在显著性差异(P<0.01)。3个患者组之间仅优良疗效组的整个颈髓、脊髓侧束和后束的FA值与一般疗效组有显著性差异(P<0.05)。除后束MD值外,CSM患者所有脊髓神经束感兴趣区中的FA、MD和RD值均与神经功能改善率有显著相关性(P<0.05);FA值在所有脊髓神经束感兴趣区中与神经功能改善率呈正相关,MD和RD值与神经功能改善率呈负相关(P<0.05),后束FA值有最好的相关性(r^2=0.253,P<0.001)。ROC分析显示FA值的曲线下面积显著大于年龄、术前JOA评分、发病时间及T2加权像中脊髓高信号(P<0.05)。脊髓侧束的FA值在预测CSM患者优良手术效果中最为准确。结论:CSM患者术前DTI参数值,尤其是脊髓后束及侧束FA值,在预测患者术后神经功能康复程度中表现出优于临床及传统影像学指标的特性,具有潜在的临床应用前景。
