| 1 | Ginkgo biloba extract improved cognitive and neurological functions of acute ischaemic stroke:a randomised controlled trial显示文摘Purpose To evaluate the efficacy and safety of Ginkgo biloba extract(GBE)in acute ischaemic stroke and its impact on the recurrence of vascular events.Methods We conducted a multicentre,prospective,randomised,open label,blinded,controlled clinical trial enrollingpatients with an onset of acute stroke within 7 days from five hospitals in China Jiangsu Province.Participants were assigned to the GBE group(450 mg GBE with 100 mg aspirin daily)or the control group(100 mg aspirin daily)for 6 months.The primary outcome was the decline in the Montreal Cognitive Assessment score at 6 months.Secondary outcomes were other neuropsychological tests of cognitive and neurological function,the the incidence of adverse events and vascular events.results 348 patients were enrolled:179 in the GBE group and 169 in the control group.With 18 patients lost to follow-up,the dropout rate was 5.17%.Admission data between two groups were similar,but in the GBE group there was a marked slow down in the decline in the Montreal Cognitive Assessment scores(−2.77±0.21 vs−1.99±0.23,P=0.0116(30 days);−3.34±0.24 vs−2.48±0.26,P=0.0165(90 days);−4.00±0.26 vs−2.71±0.26,P=0.0004(180 days))compared with controls.The National Institutes of Health Stroke Scale scores at 12 and 30 days,the modified Rankin Scale scores for independent rate at 30,90 and 180 days,and the Barthel Index scores at 30,90 and 180 days in the GBE group were significantly improved compared with controls.Improvements were also observedin GBE groups for Mini-Metal State Examination scores of 30,90 and 180 days,Webster's digit symbol test scores at 30 days and Executive Dysfunction Index scores at 30 and 180 days.No significant differences were seen in the incidence of adverse events or vascular events.conclusions We conclude that GBE in combination with aspirin treatment alleviated cognitive and neurological deficits after acute ischaemic stroke without increasing the incidence of vascular events. | Shanshan Li Xinjiang Zhang Qi Fang Junshan Zhou Meijuan Zhang Hui Wang Yan Chen Biyun Xu Yanfeng Wu Lai Qian Yun Xu | 2017 | Stroke & Vascular Neurology2017，2，4： | 25 |
| 2 | Factors Associated with Thrombolysis Outcome in Ischemic Stroke Patients with Atrial Fibrillation显示文摘The outcome of early intravenous thrombolysis for ischemic stroke in patients with atrial fibrillation(AF)is worse than that without thrombosis. How to increase the efficacy of intravenous thrombolysis for AF-related ischemic stroke remains largely unknown. In this study, we investigated factors that influence the effect of intravenous thrombolysis in these patients. Our results showed that thrombolysis was independently associated with a favorable outcome(P \ 0.001) and did not influence the mortality of AF-related ischemic stroke, although it increased the risk of hemorrhage within 24 h after treatment. Risk factors for a poor outcome at admission were:heart failure(P = 0.045); high systolic pressure(P = 0.039); high blood glucose(P = 0.030); and a high National Institutes of Health Stroke Scale(NIHSS) score(P \ 0.001). Moreover, high systolic pressure at admission(P = 0.007), high blood glucose(P = 0.027), and a high NIHSS score(P \ 0.001) were independent risk factors for mortality at 3 months. Besides thrombolysis, a high NIHSS score(P = 0.006) and warfarin taken within 48 h before stroke onset(P = 0.032) were also independent risk factors for symptomatic hemorrhage within 24 h after treatment. Ischemic stroke patients with AF benefited from intravenous thrombolysis with recombinant tissue plasminogen activator within 4.5 h after stroke. | Qiuyun Zhao Xiaobo Li Wanli Dong Min Ye Yongjun Cao Meijuan Zhang Qiantao Cheng Junshan Zhou Guofang Chen Ming Yu Shanshan Hong Xiue Wei Bei Wang Guiyun Cui Peng Zhang Hong Ding Rongzhen Xu Yan Chen Yun Xu | 2016 | Neuroscience Bulletin2016，32，2： | 13 |
| 3 | Enhancing upconversion of Nd3+ through Yb^(3+)-mediated energy cycling towards temperature sensing显示文摘Photon upconversion of lanthanides has been a powerful means to convert low-energy photons into high-energy ones.However,in contrast to the mostly investigated lanthanide ions,it has remained a challenge for the efficient upconversion of Nd^(3+)due to the deleterious concentration quenching effect.Here we report an efficient strategy to enhance the upconversion of Nd^(3+)through the Yb^(3+)-mediated energy cycling in a core-shell-shell nanostructure.Both Nd^(3+)and Yb^(3+)are confined in the interlayer,and the presence of Yb^(3+)in the Nd-sublattice provides a more matched energy for the upconversion transitions occurring at the intermediate state of Nd^(3+)towards much better population at its emissive levels.Moreover,this design also minimizes the possible cross-relaxation processes at both intermediate level and the emissive levels of Nd^(3+)which are the primary factors limiting the upconversion performance for the Nd^(3+)-doped materials.Such energy cycling-enhanced upconversion shows promise in temperature sensing. | Nan Song Songbin Liu Peng Zhang Junshan He Qinyuan Zhang Feng Wang Bo Zhou | 2021 | Journal of Rare Earths2021，39，12： | 3 |

| 6 | Preparation of ultrathin ReS2 nanosheets and their application to Q-switched Er-doped fiber lasers显示文摘We study the exfoliation of ultrathin ReS2 nanosheets from the prepared ReS2 powder and their application to Q-switched Er-doped fiber laser.XRD,Raman,and XPS spectra confirm the successful preparation of the layered ReS2.SEM images show that the obtained ReS2 sheets have lateral size below 200 nm.The thickness of the ReS2 nanosheets is smaller than 5 nm according to the AFM results.ReS2/PVA film is applied as a saturable absorber in an Er-doped Q-switched fiber laser,and a minimum pulse duration of 2.4μs and an output power of 1.25 mW are obtained,indicating the potential application to Q-switched lasers. | Junshan HE Guohua ZENG Shaoxian LIU Haiming LU Ruixian XIE Jingjing QI Lili TAO Bo ZHOU | 2021 | Frontiers of Information Technology & Electronic Engineering2021，22，3： | 0 |
| 7 | Rh(Ⅱ)-catalyzed intermolecular carboamination of pyridines via double Csp^(2)-H bond activations显示文摘We disclose the development of the Rh-catalyzed amine-directed remote 5,6-carboamination protocol of pyridines via dual Csp^(2)-H functionalizations.A variety of readily available 2-aminopyridines and 1,2,3-triazoles are allowed for coupling cyclization to access polyfunctionalized azaindoles.Mechanistic studies including DFT calculations unveil that relay carbenoidelectrophilic addition to pyridines and the sequential pyridyl Csp^(2)-H amination are involved in this transformation.The postsynthetic utility of this methodology is showcased by versatile and site-selective modification of azaindoles. | Zhongfeng Luo Jingxing Jiang Lifang Zou Xiaoyu Zhou Junshan Liu Zhuofeng Ke Fengjuan Chen Huanfeng Jiang Wei Zeng | 2024 | Science China Chemistry2024，67，1： | 0 |
