| 1 | Special Section:SARS-CoV-2 Preliminary evidence from a multicenter prospective observational study of the safety and efficacy of chloroquine for the treatment of COVID-19显示文摘Effective therapies are urgently needed for the SARS-CoV-2 pandemic.Chloroquine has been proved to have antiviral effect against coronavirus in vitro.In this study,we aimed to assess the efficacy and safety of chloroquine with different doses in COVID-19.In this multicenter prospective observational study,we enrolled patients older than 18 years old with confirmed SARS-CoV-2 infection excluding critical cases from 12 hospitals in Guangdong and Hubei Provinces.Eligible patients received chloroquinephosphate s00 mg,orally,once(half dose)or twice(full dose)daily.Patients treated with non-chloroquine therapy were included as historical controls.The primary endpoint is the time to undetectable viral RNA.Secondary outcomes include the proportion of patients with undetectable viral RNA by day 10 and 14,hospitalization time,duration of fever,and adverse events.A total of 197 patients completed chloroquine treatment,and 176patients were included as historical controls.The median time to achieve an undetectable viral RNA was shorter in chloroquine than in non-chloroquine(absolute difference in medians-6.0 days;95%CI-6.0 to—4.0).The duration of fever is shorter in chloroquine(geometric mean ratio 0.6;95%CIO.5 to 0.8).No serious adverse events were observed in the chloroquine group.Patients treated with half dose experienced lower rate of adverse events than with full dose.Although randomized trials are needed for further evaluation,this study provides evidence for safety and efficacy of chloroquine in COVID-19 and suggests that chloroquine can be a cost-effective therapy for combating the COVID-19 pandemic. | Mingxing Huang Man Li Fei Xiao Pengfei Pang Jiabi Liang Tiantian Tang Shaoxuan Liu Binghui Chen Jingxian Shu Yingying You Yang Li Meiwen Tang Jianhui Zhou Guanmin Jiang Jingfen Xiang Wenxin Hong Songmei He Zhaoqin Wang Jianhua Feng Changqing Lin Yinong Ye Zhilong Wu Yaocai Li Bei Zhong Ruilin Sun Zhongsi Hong Jing Liu Huili Chen Xiaohua Wang Zhonghe Li Duanqing Pei Lin Tian Jinyu Xia Shanping Jiang Nanshan Zhong Hong Shan | 2020 | National Science Review2020，7，9： | 20 |
| 2 | Optical nonlinearity and ultrafast dynamics of ion exchanged silver nanoparticles embedded in soda-lime silicate glass显示文摘Ag nanoparticles embedded in soda-lime silicate glass were fabricated by ion-exchange and subse-quently annealing method. Z-scan technique, femtosecond time-resolved optical Kerr effect (OKE) technique and femtosecond pump-probe experiment were used to investigate the effects of laser wavelength and laser pulse duration as well as annealing temperature on the third-order optical nonlinearity and ultrafast dynamics of the composites. It was found that the third-order susceptibility of Ag nanoparticles composite glass measured by 400 nm pulse source is larger than that measured by 800 nm pulse source due to an enhancement effect of local field near surface plasmon resonance of Ag nanoparticles in silicate glass. The third-order optical nonlinearity measured by ns laser source is about two orders of magnitude larger than that measured from fs pulse. The annealing temperature has an important effect on the third-order optical nonlinearity and ultrafast dynamics of the composites. Third-order nonlinear susceptibility up to 10?10 esu and fast relaxation process up to 0.2 ps have been obtained in Ag nanoparticles doped glass. | YANG XiuChun LI ZhiHui LlWeiJie XU JingXian DONG ZhiWei QIAN ShiXiong | 2008 | Chinese Science Bulletin2008，53，5： | 10 |
| 3 | Quantum proxy signature scheme with public verifiability显示文摘In recent years, with the development of quantum cryptography, quantum signature has also made great achievement. However,the effectiveness of all the quantum signature schemes reported in the literature can only be verified by a designated person.Therefore, its wide applications are limited. For solving this problem, a new quantum proxy signature scheme using EPR quantumentanglement state and unitary transformation to generate proxy signature is presented. Proxy signer announces his public key whenhe generates the final signature. According to the property of unitary transformation and quantum one-way function, everyone canverify whether the signature is effective or not by the public key. So the quantum proxy signature scheme in our paper can be publicverified. The quantum key distribution and one-time pad encryption algorithm guarantee the unconditional security of this scheme.Analysis results show that this new scheme satisfies strong non-counterfeit and strong non-disavowal. | ZHOU JingXian ZHOU YaJian NIU XinXin YANG YiXian | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，10： | 6 |
| 4 | Comparison of nonhuman primates identified the suitable model for COVID-19显示文摘Identification of a suitable nonhuman primate(NHP)model of COVID-19 remains challenging.Here,we characterized severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection in three NHP species:Old World monkeys Macaca mulatta(M.mulatta)and Macaca fascicularis(M.fascicularis)and New World monkey Callithrix jacchus(C.jacchus).Infected M.mulatta and M.fascicularis showed abnormal chest radiographs,an increased body temperature and a decreased body weight.Viral genomes were detected in swab and blood samples from all animals.Viral load was detected in the pulmonary tissues of M.mulatta and M.fascicularis but not C.jacchus.Furthermore,among the three animal species,M.mulatta showed the strongest response to SARS-CoV-2,including increased inflammatory cytokine expression and pathological changes in the pulmonary tissues.Collectively,these data revealed the different susceptibilities of Old World and New World monkeys to SARS-CoV-2 and identified M.mulatta as the most suitable for modeling COVID-19. | Shuaiyao Lu Yuan Zhao Wenhai Yu Yun Yang Jiahong Gao Junbin Wang Dexuan Kuang Mengli Yang Jing Yang Chunxia Ma Jingwen Xu Xingli Qian Haiyan Li Siwen Zhao Jingmei Li Haixuan Wang Haiting Long Jingxian Zhou Fangyu Luo Kaiyun Ding Daoju Wu Yong Zhang Yinliang Dong Yuqin Liu Yinqiu Zheng Xiaochen Lin Li Jiao Huanying Zheng Qing Dai Qiangming Sun Yunzhang Hu Changwen Ke Hongqi Liu Xiaozhong Peng | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 5 |

| 6 | Long- versus short-interval follow-up after resection of hepatocellular carcinoma: a retrospective cohort study显示文摘Background:Average postoperative follow-up intervals vary in patients undergoing hepatocellular carcinoma(HCC)resection because of limited evidence regarding the optimal interval.We aimed to compare the associations of long-versus short-interval follow-up with survival and recurrence in risk-stratified HCC patients.Methods:We performed a retrospective cohort study between 2007 and 2014.In total,1227 patients treated by curative resection of Barcelona Clinic Liver Cancer stage A or B HCC were stratified as having a low(n=865)or high(n=362)risk of early recurrence(within the first 2 years after resection)based on prognostic factors identified by the least absolute shrinkage and selection operation algorithm.Patients were further classified into long-interval(every 4-6 months)and short-interval(every 2-4 months)follow-up subgroups based on follow-up within 2 years after resection(low risk,long vs.short:n=390 vs.n=475;high-risk,long vs.short:n=149 vs.n=213).Results:The short-interval follow-up did not prolong overall survival in either the low-risk(hazard ratio[HR]=1.152;95%confidence interval[CI]0.720-1.843)or high-risk(HR=1.213;95%CI 0.702-2.094)patients.Early recurrence occurred in 401 patients.For high-risk patients,the short-interval follow-up subgroup exhibited smaller intrahepatic recurrence than did the long-interval group(2.6 vs.3.5 cm,respectively,P=0.045).However,no significant difference in the rate of Barcelona Clinic Liver Cancer stage 0/A recurrence was found between the long-and short-interval follow-up groups in either low-or high-risk patients(63.1%vs.68.2%,respectively,P=0.580;31.3%vs.41.5%,respec-tively,P=0.280).The rate of curative intent treatment for recurrence(34.5%vs.39.7%,respectively,P=0.430;14.6%vs.20.3%,respectively,P=0.388)was also similar between the follow-up groups for low-and high-risk patients.Conclusions:Shortening the postoperative follow-up interval from every 4-6 months to every 2-4 months within the first 2 years after resection did not increase the rate of curative intent treatment or prolong the overall survival of patients with Barcelona Clinic Liver Cancer stage A or B HCC. | Wei He Yun Zheng Ruhai Zou Jingxian Shen Junping Yang Jiliang Qiu Qiang Tao Wenwu Liu Zhiwen Yang Yuanping Zhang Binkui Li Yunfei Yuan | 2018 | Cancer Communications2018，38，1： | 2 |

| 8 | The semiannual variation of transpolar arc incidence and its relationship to the Russell–McPherron effect显示文摘Earth’s aurora is a luminescent phenomenon generated by the interaction between magnetospheric precipitating particles and the upper atmosphere;it plays an important role in magnetosphere–ionosphere(M-I)coupling.The transpolar arc(TPA)is a discrete auroral arc distributed in the noon-midnight direction poleward of the auroral oval and connects the dayside to the nightside sectors of the auroral oval.Studying the seasonal variation of TPA events can help us better understand the long-term variation of the interaction between the solar wind,the magnetosphere,and M-I coupling.However,a statistical study of the seasonal variation of TPA incidence has not previously been carried out.In this paper,we have identified 532 TPA events from the IMAGE database(2000–2005)and the Polar database(1996–2002),and calculated the incidence of TPA events for different months.We find a semiannual variation in TPA incidence.Clear peaks in the incidence of TPAs occur in March and September;a less pronounced peak appears in November.We also examine seasonal variation in the northward interplanetary magnetic field(IMF)over the same time period.The intensity and occurrence rate of the northward IMF exhibit patterns similar to that of the TPA incidence.Having studied IMF Bz before TPA onset,we find that strong and steady northward IMF conditions are favorable for TPA formation.We suggest that the semiannual variation observed in TPA incidence may be related to the Russell–McPherron(R-M)effect due to the projection effect of the IMF By under northward IMF conditions. | Tao Tang Jun Yang QuanQi Shi AnMin Tian Shi-Chen Bai Alexander William Degeling SuiYan Fu JingXian Liu Tong Shao ZeYuan Sun | 2020 | Earth and Planetary Physics2020，4，6： | 1 |

| 10 | A Regulating Capacity Determination Method for Pumped Storage Hydropower to Restrain PV Generation Fluctuations显示文摘The variable speed and constant frequency pumped storage hydropower(PSH)unit can strongly support the complementation and joint power supply of cascaded hydropower and photovoltaic(PV)plants.Its fast response capability has provided a feasible solution for the rapid power and voltage regulation caused by real-time fluctuations of PV systems.However,currently there is a lack of research on precise evaluation on regulation capability and regulating capacity configuration for PSH to restrain the real-time fluctuations.In this paper,a cascaded hydro-PV-PSH complementary joint power system(CHPP)is studied,and a“rule-based”method for regulating capacity determination is proposed.A combined statistical technique is introduced to analyze the initial estimated regulating capacity of PSH.A continuous cyclic revision method is adopted to renew the ideal PV curve by repeatedly using the main operating constraints until an optimal regulating capacity of PSH matching the PV generation scale is achieved.The results of the case study verified the feasibility and effectiveness of PSH for restraining the fast fluctuations of PV systems in real-time,and the configuration between PV and PSH regulating capacity is obtained with real-time application requirements.Finally,analyses including weather conditions,curtailed energy and electricity shortage,the sensitivity analysis,and state transition frequency are presented to demonstrate the robustness of this study. | Shuai Zhang Yue Xiang Junyong Liu Jichun Liu Jingxian Yang Xu Zhao Shafqat Jawad Jing Wang | 2022 | CSEE Journal of Power and Energy Systems2022，8，1： | 1 |

| 12 | Data-driven Optimal Dynamic Dispatch for Hydro-PV-PHS Integrated Power Systems Using Deep Reinforcement Learning Approach显示文摘To utilize electricity in a clean and integrated manner,a zero-carbon hydro-photovoltaic(PV)-pumped hydro storage(PHS)integrated power system is studied,considering the uncertainties of PV and load demand.It is a challenge for operators to develop a dynamic dispatch mechanism for such a system,and traditional dispatch methods are difficult to adapt to random changes in the actual environment.Therefore,this study proposes a real-time dynamic dispatch strategy considering economic operation and complementary regulatory ability.First,the dynamic dispatch of a hydro-PV-PHS integrated power system is presented as a multi-objective optimization problem and the weight factor between different goals is effectively calculated using information entropy.Afterwards,the dispatch model is converted into the Markov decision process,where the dynamic dispatch decision is formulated as a reinforcement learning framework.Then,a deep deterministic policy gradient(DDPG)is deployed towards the online decision for dispatch in continuous action spaces.Finally,a case study is applied to evaluate the performance of the proposed method based on a real hydroPV-PHS integrated power system in China.Simulations show that the system agent reduces the power volatility of supply by 26.7%after hydropower regulating and further relieves power fluctuation at the point of common coupling(PCC)to the upperlevel grid by 3.28%after PHS participation.The comparison results verify the effectiveness of the proposed method. | Jingxian Yang Jichun Liu Yue Xiang Shuai Zhang Junyong Liu | 2023 | CSEE Journal of Power and Energy Systems2023，9，3： | 1 |

| 14 | 肝癌切除术后的长间隔与短间隔随访:一项回顾性队列研究显示文摘背景与目的由于缺乏证据证明肝细胞癌(hepatocellular carcinoma,HCC)切除术后的最佳随访间隔,术后患者接受随访的平均时间间隔不同。我们的目的是比较长间隔随访和短间隔随访与生存和复发的相关性在不同风险分层肝癌患者中的差异。方法我们在2007年至2014年期间进行了一项回顾性队列研究。共有1227例巴塞罗那临床肝癌分期A期或B期的患者接受了根治性切除术。根据最小绝对收缩和选择操作算法为基础的预后因素分析,我们将患者分层为有低风险(n=865)或高风险(n=362)早期复发(切除术后2年内)的2组。根据切除术后2年内的随访情况,患者进一步分为长间隔(每4–6个月)随访和短期间隔(每2–4个月)随访的亚组(低风险,长期vs.短期:n=390 vs. n=475;高风险,长期vs.短期:n=149 vs. n=213)。结果不管在低风险[风险比(hazard ratio,HR)=1.152;95%置信区间(confidenceinterval,CI):0.720–1.843]还是高风险(HR=1.213;95%CI:0.702–2.094)患者中,短间隔随访没有延长患者的总生存期。401例患者出现早期复发。在高风险患者中,与长间隔随访组相比,短间隔组肝内复发肿瘤较小(2.6 cm vs. 3.5 cm,P=0.045)。但是,对于巴塞罗临床肝癌分期0/A期,长间隔与短间隔随访不管在低风险还是高风险患者中复发率(63.1%vs. 68.2%,P=0.580;31.3%vs. 41.5%,P=0.280)差异均无统计学意义。类似的,根治性切除术后,长间隔或短间隔随访分别在低风险和高风险患者中的复发率(34.5%vs. 39.7%,P=0.430;14.6%vs. 20.3%,P=0.388)差异也均无统计学意义。结论对于巴塞罗那临床肝癌分期A期或B期的患者,在接受了根治性切除术后的前2年内,将随访时间从4–6月缩短为2–4个月并不能增加根治性切除术的成功率或延长患者生存时间。 | Wei He Yun Zheng Ruhai Zou Jingxian Shen Junping Yang Jiliang Qiu Qiang Tao Wenwu Liu Zhiwen Yang Yuanping Zhang Binkui Li Yunfei Yuan | 2018 | 癌症2018，37，12： | 0 |

| 18 | Isatis indigotica:from(ethno)botany,biochemistry to synthetic biology显示文摘Isatis indigotica Fort.(Chinese woad)is a species with an ancient and well-documented history as an indigo dye and medicinal plant.It is often confused with Isatis tinctoria L.(European woad),a medicinal plant in Europe.Here,the differences between I.indigotica and I.tinctoria are systematically described.The usage development history,clinical applications and pharmacological activities,and chemical components of I.indigotica are also summarized.Lignans,indole alkaloids,and their corresponding derivatives have been identified as the major active ingredients of I.indigotica and are associated with anti-viral,anti-inflammatory,anti-cancer,and other health-promoting activities.Notable progress has been made in understanding the biosynthetic pathway and regulation mechanism of lignans and indole alkaloids in I.indigotica,the results from which should facilitate the process of targeted metabolic engineering or synthetic biology.Moreover,multiple biotechnology methods such as polyploid breeding and genetic engineering have been used with I.indigotica to result in,for example,greater yields,higher levels of bioactive component accumulation,and enhanced stress tolerance to salt,drought,and insects.Some issues require additional analyses,and suggestions for future research on I.indigotica are also discussed. | Jingxian Feng Doudou Huang Yingbo Yang Junfeng Chen Shi Qiu Zongyou Lv Xueqi Ma Yuanyu Li Rongrong Li Ying Xiao Wansheng Chen | 2021 | Molecular Horticulture2021，1，1： | 0 |
| 19 | Boosting oxygen evolution reactivity by modulating electronic structure and honeycomb-like architecture in Ni_(2)P/N,P-codoped carbon hybrids显示文摘Oxygen evolution reaction(OER)as the foremost stumbling block to generate cost-effective clean fuels has received extensive attention in recent years.But,it still maintains the challenge to manipulate the geometric and electronic structure during single reaction process under the same conditions.Herein,we report a simple self-template strategy to generate honeycomb-like Ni_(2)P/N,P-C hybrids with preferred electronic architecture.Experiments coupled with theoretical results revealed that the synthesized catalyst has two characteristics:firstly,the unique honeycomb-like morphology not only enables the fully utilization of catalytic active sites but also optimizes the mass/electron transportation pathway,which favor the diffusion of electrolyte to accessible active sites.Secondly,N,P-C substrate,on the one hand,largely contributes the electronic distribution near Fermi level(E_(F))thus boosting its electrical conductivity.On the other hand,the support effect result in the upshift of d-band center and electropositivity of Ni sites,which attenuates the energy barrier for the adsorption of OH~àand the formation of*OOH.In consequence,the optimized Ni_(2)P/N,P-C catalysts feature high electrocatalytic activity towards OER(a low overpotential of 252 m V to achieve10 m A cm^(-2))and 10 h long-term stability,the outstanding performance is comparable to most of transition metal catalysts.This work gives a innovative tactics for contriving original OER electrocatalysts,inspirng deeper understanding of fabricating catalysts by combining theoretical simulation and experiment design. | Menglei Yuan Yu Sun Yong Yang Jingxian Zhang Sobia Dipazir Tongkun Zhao Shuwei Li Yongbing Xie He Zhao Zhanjun Liu Guangjin Zhang | 2021 | Green Energy & Environment2021，6，6： | 0 |
