ABSTRACT
ObjectiveTo visually analyze the current status, hot spots and frontiers of the researches on transcranial magnetic stimulation for stroke in recent five years. MethodsLiterature related to transcranial magnetic stimulation for stroke were retrieved from the Web of Science Core Collection from January 1, 2018 to December 31, 2022, and a visualized analysis was performed using CiteSpace 6.1.R6 software. ResultsThe number of published papers increased year by year, the most prolific author was Abo Masahiro, the country with the largest number of articles was China, and Sun Yat-sen University published the most papers. The hot keywords were cerebral cortex, functional magnetic resonance imaging, cortical excitability, plasticity, etc. The top five keywords of bursting strength were unilateral spatial neglect, poststroke, neuropathic pain, cortical plasticity, and trancallosal inhibition. ConclusionThe popularity of studies on transcranial magnetic stimulation in the treatment of stroke is increasing year by year. In the future, attention can be paid to the therapeutic effect of transcranial magnetic stimulation on unilateral spatial neglect, neuropathic pain, etc. Additionally, the influence of transcranial magnetic stimulation on cortical plasticity can be further studied.
ABSTRACT
ObjectiveTo investigate the effects of an intelligent aerobic bicycle training on lower limb motor function, cardiopulmonary function and activities of daily living (ADL) in patients with ischemic stroke at different courses. MethodsFrom November, 2019 to November, 2021, 138 ischemic stroke patients were stratified-randomly divided into control group (n = 69) and experimental group (n = 69). All the patients received medication and routine rehabilitation training, and the experimental group additionally received intelligent aerobic bicycle training, for eight weeks. They were assessed with Fugl-Meyer Assessment-Lower Extremities (FMA-LE), peak oxygen uptake (VO2peak), Six-minute Walk Test (6MWT) and modified Barthel Index (MBI) before, and four weeks and eight weeks after treatment. ResultsThe performances of FMA-LE, VO2peak, 6MWT and MBI improved in both groups after treatment (|t| > 6.763, P < 0.001), and improved more in the experimental group than in the control group (|t| > 2.439, P < 0.05). For the patients beginning training less than one month after stroke, the performances of FMA-LE, VO2peak and 6MWT improved more in the experimental group than in the control group (|t| > 2.036, P < 0.05); for those during one to three months, the performances of 6MWT and MBI improved more (|t| > 2.005, P < 0.05); for those during three to six months, the performances of all the tests were not significantly different (|t| < 1.303, P > 0.05). ConclusionIntelligent aerobic bicycle training may improve the lower limb motor function, cardiopulmonary function and ADL for patients with ischemic stroke, especially intervening earlier.
ABSTRACT
Objective:To investigate the mechanism of IL-6 affecting the expression of CD73 on human placenta-derived mesenchymal stem cells (hPMSCs) and regulating their migration, adhesion and proliferation.Methods:Flow cytometry (FCM) and Western blot were used to analyze the effects of exogenous IL-6 or IL-6 secreted by hPMSCs on the expression of CD73 on hPMSCs. The influence of IL-6 on the phosphorylation of signal transducer and activator of transcription 3 (p-STAT3) in hPMSCs was detected by monoclonal antibody blocking test and Western blot. Real-time cellular analysis (RTCA) was used to analyze the changes in the migration, adhesion and proliferation of hPMSCs after knockdown of CD73 expression or APCP pretreatment.Results:FCM and Western blot showed that both exogenous and autocrine IL-6 from hPMSCs promoted the expression of CD73 on hPMSCs ( P<0.001, P<0.01). Moreover, CD73 expression decreased significantly with the presence of IL-6R inhibitor ( P<0.01). IL-6 could up-regulate the levels of both p-STAT3 and CD73 in hPMSCs ( P<0.05, P<0.01), while CD73 expression decreased after adding STAT3 inhibitor ( P<0.01). RTCA showed that knockdown of CD73 expression on hPMSCs significantly inhibited the adhesion and proliferation ability of hPMSCs( P<0.01, P<0.05), but promoted the migration ability of hPMSCs ( P<0.05). Similarly, inhibiting the hydrolase activity of CD73 on hPMSCs by APCP also resulted in a significant decrease in the adhesion and proliferation capacities of hPMSCs, and an increase in the migration capacity of hPMSCs ( P<0.05). Conclusions:IL-6 enhanced the expression of CD73 on hPMSCs via the JAK/STAT3 pathway, thus affecting the migration, adhesion and proliferation of hPMSCs.
