RÉSUMÉ
ObjectiveTo analyze the current status, hotspots and trends of researches related to non-invasive brain stimulation for Parkinson's disease in the last decade. MethodsLiterature related to non-invasive brain stimulation for Parkinson's disease in the Web of Science Core Collection was searched from January, 2014, to December, 2023, and CiteSpace 6.1.R3 was used to draw a knowledge map of authors, institutions, countries and keywords. ResultsA total of 1 351 papers were included, with a general upward trend in the number of publication, with the United States, Italy and China being the high-producing countries, and the University of London being the most prolific institution, with Alfredo Berardelli being the most prolific author. Hot keywords included deep brain stimulation, motor cortex and basal ganglia, and emergent words that have appeared in the last two years included therapy, non-invasive brain stimulation, supplementary motor areas and movement disorders. ConclusionThe research hotspots related to non-invasive brain stimulation for Parkinson's disease in the last decade mainly focus on the stimulation on motor cortical areas, the combined application of non-invasive brain stimulation and deep brain stimulation, and non-invasive brain stimulation and non-invasive neuroimaging techniques, such as electroencephalography and functional imaging. Non-invasive brain stimulation of supplementary motor areas can be further explored to improve movement disorders in Parkinson's disease patients in the future.
RÉSUMÉ
Objective To investigate the protective effect of hydrogen-rich saline on systemic oxidative stress in rats with severe traumatic brain injury(STBI) .Methods Male Wistar rats(n=60) were divided into three groups randomly :sham group ,STBI+normal saline group ,STBI+ hydrogen-rich saline group .STBI model was induced by controlled cortical impact injury .Hydrogen-rich saline were intraperitoneally administered at 5 min after STBI operation .Plasma malondialdehyde (MDA ) ,Superoxide Dis-mutase(SOD) activity and glutathione peroxidase(GSH-PX) activity were measured before TBI operation ,12 ,24 h and 48 h after TBI operation .Results The level of MDA in STBI group plasma was significantly elevated from 24 h to 48 h after STBI operation (P< 0 .05) .Hydrogen-rich saline treatment significantly attenuated the increase of MDA level in STBI operation animals (P<0 .05) .The activities of SOD and GSH-PX were slightly elevated at 6 h after TBI operation ,but decreased significantly from 24 h to 48 h after STBI operation(P<0 .05) .Hydrogen-rich saline treatment significantly increased the activities of SOD and GSH-PX after STBI operation(P<0 .05) .Conclusion Hydrogen-rich saline could exert a protective effect against STBI via reducing oxidative stress .Molecular hydrogen might be a more effective therapeutic strategy for TBI patients .
