| 1 | GRADE指南:Ⅷ.证据质量评价--间接性显示文摘直接证据来自直接比较我们关注的干预措施用于我们关注的患者人群,并测量患者重要结局的研究。间接证据可由以下4种方式之一产生。第一,患者可能与我们关注的患者不同(适用性一词常用于这类间接性)。第二,所检验的干预措施可能与我们关注的干预措施不同。有关患者和干预措施间接性的决策取决于对生物或社会因素差异是否大到可能使效应尺度出现预期的较大差异的考虑。第三,结果可能有别于最初设定的结局指标——如替代结果本身不重要,但测量之是基于替代结果的变化反映患者重要结局变化这一假设。第四类间接性在概念上与前三类不同,发生于临床医生必须在未经直接比较的两种干预措施间做出选择时。这种情况下比较治疗方案需要特定的统计方法,并根据患者人群、联合干预措施、结局测量指标及备选干预措施试验方法的差异程度,将证据级别降低1或2级。 | Gordon Guyatt Andrew D.Oxman Regina Kunz James Woodcock Jan Brozek Mark Helfand Pablo Alonso-Coello Yngve Falck-Ytter Roman Jaeschke Gunn Vist Elie A.Akl Piet N Post Susan Norris Joerg Meerpohl Mona Nasser 代表GRADE工作组 李幼平 杨晓妍 李鸿浩 | 2011 | 中国循证医学杂志2011，11，12： | 30 |
| 2 | 2018加拿大心境障碍与焦虑障碍治疗协作组/国际双相障碍学会指南:双相障碍的管理显示文摘加拿大心境障碍与焦虑障碍治疗协作组(Canadian Network for Mood and Anxiety Treatments,CANMAT)曾于2005年发布了第1版双相障碍管理指南,并分别于2007、2009和2013年对该指南进行了更新,其中最近的2次更新是与国际双相障碍学会(International Society for Bipolar Disorders,ISBD)合作完成。2018版CANMAT/ISBD双相障碍治疗指南(以下简称指南)反映了自2005年首版指南发表以来本领域取得的重大进展,包括疾病诊断与疾病管理的更新以及药物治疗与心理治疗的近期研究进展。这些前沿进展中综合考虑了循证证据的级别,并基于治疗疗效、临床实践经验、安全性、耐受性和药物导致的转相风险等,对一线、二线及三线治疗方案进行了简明而清晰的推荐。本指南中新增内容涵盖了双相Ⅰ型障碍(BD-Ⅰ)的躁狂发作急性期、抑郁发作急性期和双相障碍维持期的一线及二线治疗推荐等级划分。这种对治疗推荐等级的划分综合考虑了治疗方法对双相障碍不同时相的影响,将进一步帮助临床医生做出基于循证证据的治疗决策。锂盐、喹硫平、双丙戊酸盐、阿塞那平、阿立哌唑、帕利哌酮、利培酮和卡利拉嗪单药或联合使用被推荐为躁狂发作急性期的一线治疗选择。BD-Ⅰ抑郁期的一线治疗选择包括喹硫平、鲁拉西酮、锂盐、拉莫三嗪单药,鲁拉西酮联合锂盐或双丙戊酸盐或拉莫三嗪辅助治疗。尽管急性期治疗有效的药物通常应继续用于BD-Ⅰ的维持期治疗,但也存在一些特殊情况(例如抗抑郁药)。现有数据表明,锂盐、喹硫平、双丙戊酸盐、拉莫三嗪、阿塞那平和阿立哌唑单药或联合治疗应被视为维持治疗的初始或更换治疗方案时的一线选择。除了探讨BD-Ⅰ的相关问题外,本指南中还对双相Ⅱ型障碍(BD-Ⅱ)的临床管理进行了系统回顾并给予治疗推荐,同时针对特殊人群也有相关推荐,如处于各个生殖周期的女性、儿童、青少年和老年人。此外,本指南中还讨论了特定精神疾病及共病(如物质滥用、焦虑障碍和代谢性疾病)的影响。最后,本指南中概述了安全性和药物监测的相关问题。CANMAT/ISBD工作组希望本指南能够成为全球临床医生的实用工具。 | Lakshmi N Yatham Sidney H Kennedy Sagar V Parikh Ayal Sehaffer David J Bond Benicio N Frey Verinder Sharma Benjamin I Goldstein Soham Rej Serge Beaulieu Martin Alda Glenda MaeQueen Roumen V Milev Arun Ravindran Claire O'Donovan Diane Mclntosh Raymond W Lam Gustavo Vazquez Flavio Kapczinski Roger S Melntyre Jan Kozicky Shigenobu Kanba Beny Lafer Trisha Suppes Joseph R Calabrese Eduard Vieta Gin Malhi Robert M Post Michael Berk 胡晨(译) 王刚(译) | 2019 | 中华精神科杂志2019，52，1： | 25 |

| 4 | Quasi-secure quantum dialogue using single photons显示文摘A quasi-secure quantum dialogue protocol using single photons was proposed. Different from the previous entanglement-based protocols, the present protocol uses batches of single photons which run back and forth between the two parties. A round run for each photon makes the two parties each obtain a classical bit of information. So the efficiency of information transmission can be increased. The present scheme is practical and well within the present-day technology. | YANG YuGuang1,2 & WEN QiaoYan31 College of Computer Science and Technology, Beijing University of Technology, Beijing 100022, China 2 State Key Laboratory of Information Security, Graduate University of the Chinese Academy of Sciences, Beijing 100049, China 3 School of Science, Beijing University of Posts and Telecommunications, Beijing 100876, China | 2007 | Science China(Physics,Mechanics & Astronomy)2007，50，5： | 18 |
| 5 | A class of discounted models for singular diffusion control显示文摘A kind of discounted problems for singular diffusion control have been studied. The drift and diffusion coefficients of state process are nonlinear. The class of models has been basically extended from a corresponding one established by Karatzes et al. before. By applying some analysis methods different from earlier works, the sufficient and necessary conditions of the existence of optimal control have been obtained. If an optimal control exists, it is a 'transient reflection' of state process for two lines. | LIU Kunhui, QIN Mingda & LU Chuanlai1.

| 6 | RPPK modulation with high data rates显示文摘With the development of communication technology, the precious frequency spectrum is becoming more and more crowded. Exploiting the particular filter with zero group delay, ultra narrow band (UNB) modulation is intended for acquiring the high frequency efficiency. Unfortunately, this UNB filter is confronted with great challenges from the classical communication theories. The validation on its realization is also difficult. This paper proposes a novel UNB modulation, namely random pulse position keying (RPPK). It is demonstrated from analysis that there is no inessential discrete spectral line in modulated signal’s power density spectrum (PDS), and the UNB filter has been successfully avoided. Consequently, RPPK is rather explicit in theory and simple in implementation. As is shown by the simulation, the frequency utilization of RPPK can even reach 100 bits/s/Hz. Its optimum receiving performance is slightly inferior to BPSK, yet is much superior to that of other UNB modulations such as VMSK/2. Moreover, multi-access and confidentiality are additional benefits to UNB users. | LI Bin , ZHOU Zheng & ZOU WeiXia Key Laboratory of Universal Wireless Communications, Ministry of Education Wireless Network Laboratory, Beijing University of Posts and Telecommunications, Beijing 100876, China | 2010 | Science China(Information Sciences)2010，53，2： | 16 |
| 7 | Hepatitis B and C virus-induced hepatitis: Apoptosis, autophagy, and unfolded protein response显示文摘AIM: To investigate the co-incidence of apoptosis, autophagy, and unfolded protein response(UPR) in hepatitis B(HBV) and C(HCV) infected hepatocytes.METHODS: We performed immunofluorescence confocal microscopy on 10 liver biopsies from HBV and HCV patients and tissue microarrays of HBV positive liver samples. We used specific antibodies for LC3β, cleaved caspase-3, BIP(GRP78), and XBP1 to detect autophagy, apoptosis and UPR, respectively. AntiHCV NS3 and anti-HBs antibodies were also used to confirm infection. We performed triple blind counting of events to determine the co-incidence of autophagy(LC3β punctuate), apoptosis(cleaved caspase-3), and unfolded protein response(GRP78) with HBV and HCV infection in hepatocytes. All statistical analyses were performed using SPSS software for Windows(Version 16 SPSS Inc, Chicago, IL, United States). P-values < 0.05 were considered statistically significant. Statistical analyses were performed with Mann-Whitney test to compare incidence rates for autophagy, apoptosis, and UPR in HBV- and HCV-infected cells and adjacent noninfected cells.RESULTS: Our results showed that infection of hepatocytes with either HBV and HCV induces significant increase(P < 0.001) in apoptosis(cleavage of caspase-3), autophagy(LC3β punctate), and UPR(increase in GRP78 expression) in the HCV- and HBVinfected cells, as compared to non-infected cells of the same biopsy sections. Our tissue microarray immunohistochemical expression analysis of LC3β in HBV^(Neg) and HBV^(Pos) revealed that majority of HBVinfected hepatocytes display strong positive stainingfor LC3β. Interestingly, although XBP splicing in HBVinfected cells was significantly higher(P < 0.05), our analyses show a slight increase of XBP splicing was in HCV-infected cells(P > 0.05). Furthermore, our evaluation of patients with HBV and HCV infection based on stage and grade of the liver diseases revealed no correlation between these pathological findings and induction of apoptosis, autophagy, and UPR.CONCLUSION: The results of this study indicate that HCV and HBV infection activates apoptosis, autophagy and UPR, but slightly differently by each virus. Further studies are warranted to elucidate the interconnections between these pathways in relation to pathology of HCV and HBV in the liver tissue. | Behzad Yeganeh Adel Rezaei Moghadam Javad Alizadeh Emilia Wiechec Seyed Moayed Alavian Mohammad Hashemi Bita Geramizadeh Afshin Samali Kamran Bagheri Lankarani Martin Post Payam Peymani Kevin M Coombs Saeid Ghavami | 2015 | World Journal of Gastroenterology2015，21，47： | 13 |
| 8 | Reverse reconciliation for continuous variable quantum key distribution显示文摘An efficient and practical post-processing technique based on reverse reconciliation for continuous variable quantum key distribution is proposed and simulated with low-density parity check (LDPC) codes. MultiLevel Coding/ MultiStage Decoding, which fully utilizes optimization technique such as vector quantization and iterative decoding and the optimal channel coding most close to the Shannon limit, was used to realize efficient reverse reconciliation algorithm. Simulation results showed that the proposed method can improve the secure key distribution rate to 2.2 kb/s and the coding efficiency to 0.89 over 20 km in single-mode optical fiber. Moreover, there still is room for much improvement. | LU ZhiXin 1,2 , YU Li 1,2 , LI Kang 1,2 , LIU BingCan 1,2,3 , LIN JianGui 1,2 , JIAO RongZhen 1,2 & YANG BoJun 1,21 School of Science, Beijing University of Posts and Telecommunications, Beijing 100876, China 2 Key Laboratory of Information Photonics and Optical Communication, Ministry of Education, Beijing University of Posts and Telecommunications, Beijing 100876, China 3 Department of Fundamental Courses, Academy of Armored Force Engineering, Beijing 100072, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，1： | 12 |
| 9 | Multiparty simultaneous quantum identity authentication with secret sharing显示文摘Two multiparty simultaneous quantum identity authentication (MSQIA) protocols based on secret sharing are presented. All the users can be authenticated by a trusted third party (TTP) simultaneously. In the first protocol,the TTP shares a random key K with all the users using quantum secret sharing. The ith share acts as the authentication key of the ith user. When it is necessary to perform MSQIA,the TTP generates a random number R secretly and sends a sequence of single photons encoded with K and R to all the users. According to his share,each user performs the corresponding unitary operations on the single photon sequence sequentially. At last,the TTP can judge whether the impersonator exists. The sec-ond protocol is a modified version with a circular structure. The two protocols can be efficiently used for MSQIA in a network. They are feasible with current technol-ogy. | YANG YuGuang1,2,WEN QiaoYan3 & ZHANG Xing4,5 1 College of Computer Science and Technology,Beijing University of Technology,Beijing 100022,China 2 State Key Laboratory of Information Security (Graduate University of the Chinese Academy of Sciences),Beijing 100049,China 3 School of Science,Beijing University of Posts and Telecommunications,Beijing 100876,China 4 Institute of Electronic Technology,Information Engineering University,Zhengzhou 450004,China 5 Trusted Computing Laboratory,Beijing University of Technology,Beijing 100022,China | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，3： | 12 |
| 10 | Threshold quantum secure direct communication without entanglement显示文摘For the first time, a threshold quantum secure direct communication (TQSDC) scheme is presented. Similar to the classical Shamir's secret sharing scheme, the sender makes n shares, S1, …, Sn of secret key K and each receiver keeps a share secretly. If the sender wants to send a secret message M to the receivers, he en-codes the information of K and M on a single photon sequence and sends it to one of the receivers. According to the secret shares, the t receivers sequentially per-form the corresponding unitary operations on the single photon sequence and ob-tain the secret message M. The shared shares may be reusable if it can be judged that there is no eavesdropper in line. We discuss that our protocol is feasible with current technology. | YANG YuGuang1,3 & WEN QiaoYan2 1 College of Computer Science and Technology, Beijing University of Technology, Beijing 100022, China 2 School of Science, Beijing University of Posts and Telecommunications, Beijing 100876, China 3 State Key Laboratory of Information Security (Graduate School of Chinese Academy of Sciences), Beijing 100049, China | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，2： | 11 |

| 12 | Channel Adaptive Shortest Path Routing for Ad Hoc Networks显示文摘Routing in Mobile Ad Hoc Network (MANET) is a challenge owing to the dynamic nature of network topology and the resource constraints. To maximize the channel resource utilization and minimize the network transfer delay along the path, the shortest path with the minimum hops approach is often adopted. However, the quality of wireless channels among the mobile nodes is time varying owing to fading, shadowing and path loss. Considering adaptive channel coding and modulation scheme, the channel state can be characterized by different link throughputs. If routing selection based on the link throughput is implemented, the minimum transfer delay from source to destination and the maximal throughput may be obtained. In this paper, a Channel Adaptive Shortest Path Routing (CASPR) is presented. Based on the adaptive channel coding and modulation, the CASPR transforms the link throughput into the channel quality factor Q and finds the shortest routing according to the Q measure. Simulation results show that the average path length in the proposed routing scheme may be slightly higher than that of the conventional shortest path with the minimum hops approach, but it can reduce the average transfer delay and increase the packet deliver rate. | TIAN Hui, XIE Fang, HU Jian dong, ZHANG Ping (Wireless Technology Innovation Labs, Beijing University of Posts & Telecommunications, Beijing 100876, P.

| 14 | Organic thin-film solar cells:Devices and materials显示文摘In recent years, the performance of organic thin-film solar cells has gained rapid progress, of which the power conversion efficiencies (ηp) of 3%-5% are commonly achieved, which were difficult to obtain years ago and are improving steadily now. The ηp of 7.4% was achieved in the year 2010, and ηp of 9.2% was disclosed and confirmed at website of Mitsubishi Chemical in April, 2011. The promising future is that the ηp of 10% is achievable according to simulation results. Apparently, these are attributed to material innovations, new device structures, and also the better understanding of device physics. This article summarizes recent progress in organic thin-film solar cells related to materials, device structures and working principles. In the device functioning part, after each brief summary of the working principle, the methods for improvements, such as absorption increment, organic/electrode interface engineering, morphological issues, are addressed and summarized accordingly. In addition, for the purpose of increasing exciton diffusion efficiency, the benefit from triplet exciton, which has been proposed in recent years, is highlighted. In the active material parts, the chemical nature of materials and its impact on device performance are discussed. Particularly, emphasis is given toward the insight for better understanding device physics as well as improvements in device performance either by development of new materials or by new device architecture. | LI ZhiGang1, ZHAO XinYan2, LI Xin1,2, GAO ZhiQiang1, MI BaoXiu1 & HUANG Wei2 1Jiangsu Engineering Centre for Flat-Panel Displays & Solid-state Lighting and School of Materials Science & Engineering, Nanjing University of Posts & Telecommunications, Nanjing 210046, China 2Key Laboratory for Organic Electronics & Information Displays (KLOEID) Institute of Advanced Materials (IAM), Nanjing University of Posts & Telecommunications, Nanjing 210046, China | 2012 | Science China Chemistry2012，55，4： | 9 |
| 15 | EXIT analysis of M-algorithm based MIMO detectors and LDPC code design optimization显示文摘This paper investigates joint design and optimization of both low density parity check (LDPC) codes and M-algorithm based detectors including iterative tree search (ITS) and soft-output M-algorithm (SOMA) in multiple-input multiple-output (MIMO) systems via the tool of extrinsic information transfer (EXIT) charts. First, we present EXIT analysis for ITS and SOMA. We indicate that the extrinsic information transfer curves of ITS obtained by Monte Carlo simulations based on output log-likelihood rations are not true EXIT curves, and the explanation for such a phenomenon is given, while for SOMA, the true EXIT curves can be computed, enabling the code design. Then, we propose a new design rule and method for LDPC code degree profile optimization in MIMO systems. The algorithm can make the EXIT curves of the inner decoder and outer decoder match each other properly, and can easily attain the desired code with the target rate. Also, it can transform the optimization problem into a linear one, which is computationally simple. The significance of the proposed optimization approach is validated by the simulation results that the optimized codes perform much better than standard non-optimized ones when used together with SOMA detector. | YOU MingHou1,2, TAO XiaoFeng1,2, CUI QiMei1,2 & ZHANG Ping1,2 1 Wireless Technology Innovation Institute, Beijing University of Posts and Telecommunications, Beijing 100876, China 2 Key Laboratory of Universal Wireless Communications, (Beijing University of Posts and Telecommunications), Ministry of Education, Beijing 100876, China | 2009 | Science in China(Series F)2009，52，12： | 9 |
| 16 | Secure network coding in the presence of eavesdroppers显示文摘Our concern, in the paper, is to construct information-theoretic secure network coding in the presence of eavesdroppers. Based on the generalized attack model and all-or-nothing transformation, the security of network coding in the generalized combination network can be characterized by the network capacity and the min-cut bound of wiretapping set from the source. Furthermore, it can be extended to any directed acyclic networks with single source. Compared with the traditional results, we construct information-theoretic secure network coding without additional encryptions and giving up any capacity. | LUO MingXing1,2,3, YANG YiXian1,2,3, WANG LiCheng1,2,3 & NIU XinXin1,2,3 1Information Security Center, State Key Laboratory of Networking and Switching Technology, Beijing University of Posts and Telecommunications, Beijing 100876, China 2Key Laboratory of Network and Information Attack and Defence Technology of MOE, Beijing University of Posts and Telecommunications, Beijing 100876, China 3National Engineering Laboratory for Disaster Backup and Recovery, Beijing University of Posts and Telecommunications, Beijing 100876, China | 2010 | Science China(Information Sciences)2010，53，3： | 8 |
| 17 | Threshold quantum secret sharing between multi-party and multi-party显示文摘A threshold quantum secret sharing (TQSS) scheme between multi-party and multi-party was proposed using a sequence of single photons,which is useful and efficient when the parties of communication are not all present. We described the process of this TQSS scheme and discussed its security. It was shown that entan-glement is not necessary for quantum secret sharing. Moreover,the theoretic effi-ciency was improved to approach 100% as almost all the instances can be used for generating the private key,and each photon can carry one bit of information.
