| 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 | Status and Suggestions of the Pesticide Use in the Protected Vegetable Fields in Shandong Province显示文摘This paper briefly introduced the issues of food safety and environmental pollution caused by pesticide residues in protected vegetables, discussed the status and problems of pesticide use in the protected vegetables in Shandong Province, and analyzed the main factors leading to the pesticide residues, including the low education of most farmers, lack of correct identification of diseases and insect pests, use of pesticides based on personal experience, pesticide preparation by bare hands, large dose of pesticide, frequent application, pesticide spraying without protection, uneven spraying, leakage of pesticide from the sprayers, etc.. Finally, based on the vegetable planting features and advantages in Shandong Province, some suggestions were proposed for references, such as, to enhance the monitoring of pesticide residue, to improve the educational level of farmers and to scentifically use the pesticide. | Bo ZHANG Yan LI Xinhao GAO Changsong LI Junshan QI Yueli ZHANG Wei ZHAO | 2013 | Asian Agricultural Research2013，5，4： | 2 |
| 3 | Effects of Neodymium Application Mode on Resistance to Fusarium Wilts in Cucumbers显示文摘The effects of neodymium application mode on the disease index, PAL, POD and PPO activity, content of lignin and generation rate of ·O2- in cucumbers were investigated by pot experiment. The results suggest that the disease index decreases after spraying Nd 3+ . Relative protection effects of at-the-same-time-group, induced-group and therapy-group are 7.51%, 27.14% and 11.51%. The PAL activity of Nd+Fo treatment in at-the-same-time-group, induced-group and therapy-group increases by 9.86%, 48.57% and 4.97% respectively compared with that of Fo treatment. The POD activity decreases by 27.52%, 35.87% and 7.67%. The PPO activity increases by 5.75%, 36.58% and 52.19%. The ·O2- generation rate decreases by 9.49%, 28.08% and 25.21%. The lignin content increases 5.55%, 5.25% and 11.25%. In conclusion, induced-group has the best effect in decreasing disease index, decreasing ·O2- generation rate and increasing PAL and POD activity; therapy-group has the best effect in increasing PPO activity and content of lignin. | Zhang Yufeng Qi Junshan Chen Kaoshan Dong Liang | 2006 | Journal of Rare Earths2006，24，5： | 1 |
| 4 | 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 |
