| 1 | Deformation-tolerant metal anodes for flexible sodium-air fiber batteries显示文摘Although flexible sodium-air(Na-air)batteries with high theoretical energy density offer promising opportunities for next-generation smart electronics,enhancing the safety and efficiency of flexible sodium metal anodes under dynamic and continuous deformation remains a challenge.Here,a flexible sodiated carbon nanotube layer to suppress dendrite growth under various deformations is demonstrated through a Fermi level-driven spontaneous synthetic process.The resulting sodiated carbon nanotube layer,which has a spontaneously formed solid-electrolyte interface and a robust interlocked structure,creates a uniformly distributed electric field and stable interface even under deformation,affording dendrite-free flexible Na metal anodes.With this deformation-tolerant Na metal anode,we have constructed a new family of highly flexible Na-air fiber batteries with excellent cycling performance for 400 cycles at a current density of 1000mA·g^(−1) and a capacity limit of 500 mAh·g^(−1) under dynamic deformation.These Na-air fiber batteries can be further woven into self-powering systems to support flexible electronic devices. | Lei Ye Xiangran Cheng Meng Liao Tiancheng Zhao Xinlin Huang Xinyue Kang Kun Zhang Xuemei Sun Bingjie Wang Huisheng Peng | 2022 | eScience2022，2，6： | 0 |
| 2 | Effectiveness and safety of Angong Niuhuang pill(安宫牛黄丸)in treatment of acute stroke:a systematic review and Meta-analysis显示文摘OBJECTIVE:To systematically evaluate the efficacy and safety of Angong Niuhuang pill(安宫牛黄丸,ANP)in the treatment of acute stroke.This can provide ideas and basis for the treatment of this disease with integrated Traditional Chinese and Western Medicine.METHODS:Randomized controlled trials(RCTs)of China National Knowledge Infrastructure Database,Wanfang Database,Chinese BioMedical Literature Database,PubMed,Embase,and the Cochrane Library were searched from the establishment to March 2022.Two researchers screened the literature and extracted the data according to inclusion and exclusion criteria.Meta-analysis was performed using RevMan 5.3 software.RESULTS:A total of 28 RCTs were included,including 2745 patients in the acute stage of stroke(1375 in the experimental group and 1370 in the control group).Metaanalysis showed that compared with conventional treatment,combined treatment with ANP could improve the effective rate of acute stroke patients[relative risk(RR)=1.26,95%confidence interval(CI)(1.21,1.31)],Glasgow Coma Scale scores[mean difference(MD)=2.01,95%CI(1.04,2.98)],Mini-mental State Examination scores[MD=4.79,95%CI(2.22,7.37)],Activities of Daily Living scores[MD=15.70,95%CI(14.05,17.36)]and the Barthel index scores[MD=13.89,95%CI(12.12,15.65)],reduce National Institute of Health stroke scale scores[MD=-3.90,95%CI(-4.96,-2.84)]and serum brain natriuretic peptide[MD=-38.50,95%CI(-46.85,-30.15)].In terms of safety,the incidence of adverse reactions showed no statistical differences between the two groups[RR=0.71,95%CI(0.43,1.15),P=0.16],and no serious adverse reactions/events were observed,indicating a good safety.CONCLUSIONS:Existing clinical research evidence shows that ANP has good efficacy and safety in the treatment of acute stroke,which can provide a basis for the treatment of integrated Traditional Chinese and Western Medicine.However,the quality of included research methodology needs to be improved,and the above conclusions need to be verified by more highquality studies. | MENG Xiangran CAO Xue SUN Minglin AI Yanke HE Liyun LIU Jia | 2023 | Journal of Traditional Chinese Medicine2023，43，4： | 0 |
