ABSTRACT
Objective:To investigate the effect of bilateral globus pallidus internus deep brain stimulation (GPi-DBS) on motor performance, quality of life, sleep quality, neuropsychological status, and mood in patients with Meige syndrome.Methods:The clinical data of 17 patients with Meige syndrome accepted bilateral GPi-DBS in Department of Neurosurgery, People's Hospital of Peking University from May 2019 to March 2021 were retrospectively analyzed. Established and validated rating scales were used to assess the motor performance, quality of life, sleep quality, neuropsychological status, and mood at baseline, and 1 and 2 years after GPi-DBS.Results:Burke-Fahn-Marsden dystonia rating scale (BFMDRS) motor total scores decreased from 14.4±6.2 at baseline to 4.3±2.2 and 3.5±1.9 at 1 and 2 years after GPi-DBS, with significant differences ( P<0.05). BFMDRS disability total scores decreased from 6.2±4.0 at baseline to 2.8±2.0 and 2.2±1.5 at 1 and 2 years after GPi-DBS, with significant differences ( P<0.05). In 36-item Short-Form Health Survey (SF-36), the scores of physical function, role-physical, general health sub-items at 1 and 2 years after GPi-DBS were significantly higher than those at baseline ( P<0.05). No significant differences were noted in scores of sleep quality, neuropsychological function, or mood scales at 1 and 2 years after GPi-DBS compared with those at baseline ( P>0.05). Conclusion:Bilateral GPi-DBS is effective and safe in Meige syndrome, which can improve dystonic symptom and quality of life without adverse effects on sleep quality, neuropsychological function, or emotional status.
ABSTRACT
Objective:To explore the pathogenesis of glossopharyngeal neuralgia (GPN) in central nervous system from perspective of brain morphology.Methods:A prospective study was performed. Twenty-seven patients with right primary GPN admitted to Department of Neurosurgery, People's Hospital of Peking University from April 2019 to June 2023 and 27 healthy subjects (controls) matched with age, gender, dominant hand, and education level during the same period were recruited. These patients were divided into GPN with neurovascular compression group ( n=18) and GPN without neurovascular compression ( n=9) based on intraoperative presence of neurovascular compression. SPM8 software based on Matlab R2017b programming platform and VBM8 toolbox were used to process the whole-brain high-resolution 3D-T1 brain structural image data of the participants and analyze the differences in the gray matter volume of each brain region between the 2 groups. Pearson correlation was applied to analyze the correlations of gray matter volumes in brain regions enjoying significant difference with baseline data and pain characteristics of these GPN patients. Results:Compared with controls, patients with GPN had significantly reduced gray matter volumes in the left anterior cingulate gyrus, middle temporal gyrus, transverse temporal gyrus, precentral gyrus, postcentral gyrus, right insula, thalamus, inferior parietal lobule, precentral gyrus, middle temporal gyrus, and inferior temporal gyrus ( P<0.05, FDR corrected). Compared with GPN patients with neurovascular compression, GPN patients without neurovascular compression had significantly reduced gray matter volume in the bilateral anterior cingulate gyrus ( P<0.05, FDR corrected). Changes of gray matter volume in the right insula were negatively correlated with disease duration of GPN patients ( r=-0.521, P=0.005). Conclusion:GPN patients have extensive gray matter atrophy in the brain, which may play an essential role in GPN development and maintenance.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the protective effect of Apelin-13 on focal cerebral ischemia-reperfusion injury in rats.</p><p><b>METHODS</b>Focal transient cerebral ischemia-reperfusion injury was induced in male SD rats using modified suture occlusion technique. The rats were randomly divided into 5 groups: Sham group, Model group, Apelin-low dose (A) group, Apelin-middle dose (B) group and Apelin-high dose (C) group. Apelin-13 was injected into lateral cerebral ventricle, and the neurological function score, brain edema, infarct volume, apoptosis, malondialdehyde (MDA), superoxide dismutase (SOD) and extracellular regulated kinase1/2 (ERK1/2) protein were measured.</p><p><b>RESULTS</b>Neurological function scores, percentage of brain water content, infarct volumes and TUNEL-positive cells in B and C groups were lower than those in Model group (P<0.05). The level of MDA in the tissue bomogenate of brain tissue in the surrounding area of ischemia of B and C groups was lower than that of Model group, while the activity of SOD was higher (P<0.05). There was no significant difference in ERK1/2 protein expression among the groups (P>0.05). P-ERK1/2 increased in Model group and A, B, and C groups compared with Sham group (P<0.05), and that of A, B, and C group was higher than that of Model group (P<0.05).</p><p><b>CONCLUSION</b>Apelin-13 may play an important role by inhibiting oxidative stress to protect against focal cerebral ischemia-reperfusion injury; ERK1/2 signaling pathway may be involved in the protective mechanism of Apelin-13.</p>
