Objective To analyze the research hotspots and frontier trends in the field of physical therapy for Parkinson's disease(PD)from 2014 to 2023.Methods Relevant literatures published from January,2014 to December,2023 were retrieved from the Web of Science Core Collection.CiteSpace 6.3.R1 was used to conduct bibliometric analysis,generating visual maps of coun-tries,institutions,keyword co-occurrence,burst terms,timelines and clustering,and they were summarized based on both visual results and literature content.Results A total of 400 articles were included.The United States had the highest publication volume,followed by China,Italy and Brazil,and the international collaboration was relatively active.Major contributing institutions included Northwestern University,Rush University,Karolinska Institutet and Universidade de S?o Paulo.Keyword co-oc-currence analysis showed that researches mainly focused on interventions such as exercise,postural control,aero-bic exercise and transcranial direct current stimulation.Burst detection analysis showed that keywords with high attention in recent years included motor symptoms,executive function,resistance training and noninvasive brain stimulation.The timeline map indicated a shift in research themes from early focus on electrical stimulation to in-tegrated interventions involving both motor and cognitive functions.Conclusion Over the past decade,researches on physical therapy for PD has shown steady growth,with increasing diver-sity in intervention strategies.There is a clear trend toward multidimensional integration and interdisciplinary col-laboration.Future studies should strengthen interventions targeting non-motor symptoms and promote the clinical application of new rehabilitation technologies.

Objective To explore the relationship of sevoflurane neurotoxicity with the expres-sion of Bid,Bim,Puma.Methods The cortical neuron from newborn SD rat (within 24 h)were see-ded in 6 or 12 well plate,and then randomly divided into 4 groups.Rat culture cortical neurons in vitro exposed in 1%,2%,4% and 0% sevoflurane for 6h were divided into A,B,C and D group. The effect of neuron viability,death and apoptosis were assessed using CCK-8,LDH and caspase-3 cleavage 1 7kDa expression assay.The expressions of Bid,Bim and Puma were assessed by western blot.Results Compared with group D, there were significant increases of neuron death and apoptosis,but a decrease of neuron viability,and upregulated expressions of Bid,Bim and Puma in group B (P <0.05);Compared with group B,Group C had increased death and apoptosis and de-creased viability of neurons,as well as upregulated expressions of Bid,Bim and Puma (P <0.05 ). Conclusion Along with the increase of the concentration,sevoflurane neurotoxicity was increased by upregulation of Bid,Bim,Puma expression.
