Alzheimer′s disease (AD) is a neurological disorder of unknown etiology characterized by memory loss and severe intellectual impairment. Transcranial direct current stimulation (tDCS) acts on the brains of AD patients in a non-invasive manner by reducing neurotoxic substances, promoting synaptic plasticity, producing long-term after-effects, weakening neuroinflammation, and reducing oxidative stress in brain tissue, among other mechanisms that affect patients′ memory functions. Therefore, tDCS has become an important tool to improve the memory of AD patients. And the effect of this treatment on memory improvement is influenced by factors such as stimulation site, current level, and stimulation duration.

Objective:To preliminarily explore the long-term improvement of low-frequency deep brain stimulation (DBS) on the nucleus basalis of Meynert (NBM) in cognitive disorders, neuropsychiatric symptoms and sleep disorders of patients with early-onset severe Alzheimer's disease (AD).Methods:A retrospective study was performed; 18 patients with early-onset severe AD admitted to Department of Neurosurgery, First Medical Center of PLA General Hospital from January 2016 to December 2022 were included. These patients were divided into NBM-DBS group and control group according to different treatments; 6 patients received low-frequency NBM-DBS on basis of conservative treatments; 12 patients accepted conservative treatments. Changes in Brief Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), Neuropsychiatric Inventory (NPI), Hamilton Depression Rating Scale (HAMD), Becker-Lavanson Mania Scale (BRMS), Pittsburgh Sleep Quality Index (PSQI), and Zarit Caregiver Burden Interview (ZBI) were observed before treatment and 1 year after follow up.Results:MMSE and MoCA scores 1 year after follow up obviously reduced compared with those before treatment in both NBM-DBS and control patients; MMSE and MoCA scores in NBM-DBS patients showed no significant differences between 1 year after follow up and before treatment ( P>0.05), while significant differences were noted in the control group between 1 year after follow-up and before treatment ( P<0.05); and no significant differences in MMSE and MoCA scores were noted between the 2 groups 1 year after follow up ( P>0.05). NPI, HAMD, BRMS and ZBI scores in the NBM-DBS group 1 year after follow up were significantly different compared with those before treatment ( P<0.05); no significant differences were noted in NPI, HAMD and ZBI scores in the control group between 1 year after follow up and before treatment ( P>0.05), while significant difference was noted in BRMS scores ( P<0.05); significant differences in NPI, HAMD, BRMS and ZBI scores were noted between the 2 groups 1 year after follow up ( P<0.05). Conclusion:Low-frequency NBM-DBS is not only effective in improving cognitive disorders, but also effective in improving neuropsychiatric symptoms and sleep disorders, as well as reducing caregiver burden in patients with early-onset severe AD.

Epilepsy is a serious chronic neurological disorder that can be detected by analysing the brain signals generated by brain neurons, with electroencephalography (EEG) becoming a key tool in the diagnosis of epilepsy. The application of specific methods for processing and analysing EEG signals is important in exploring the working mechanisms of the brain and in the diagnosis of neurological disorders of the brain. The article describes the application of EEG signals in epilepsy treatment through feature extraction, feature classification and other related analysis methods. The article presents an overview of recent research advances through the use of principal component analysis, independent component analysis, wavelet transform, linear discriminant analysis, support vector machine, artificial neural network and decision tree. It provides some reference for the detection and classification of seizures and future research directions.

Objective:To establish silicone cartilage models of donor-sites for the microtia patients by using digital technology, and to explore the application of surgical simulation in auricular reconstruction.Methods:From June 2018 to October 2019, 19 congenital microtia patients underwent thoracic CT scans and following three-dimensional costal cartilage imaging with Mimics software at the Nanfang Hospital, Southern Medical University. Among these patients, 16 were males and 3 were females. The mean age of patients was 16 years (range 8 to 35 years). Silicon cartilage models were produced by 3D printing and used for surgical planning and preoperative simulation in ear framework fabrication. Cartilaginous framework was sculptured according to the simulation during operation. Patients were followed up for a minimum of six months to evaluate the size, outline, height and auriculocephalic angle of the reconstructed ear. The satisfactory outcomes of the patients were scored according to a 5-point Likert scale.Results:All the patients received the surgical simulation and sculpture training with silicone cartilage models before operation. Auricular reconstruction was completed successfully according to the simulation. The duration of sculpture was shortened to 1-1.5 hours. There were no serious complications, such as hematoma, inflammation, skin necrosis and framework exposure. The contour of reconstructed ear was natural and clear over a 6 months follow-up, and all the patients were satisfied with their surgical outcomes.Conclusions:With the application of digital technology and silicone cartilage models by 3D printing to the surgical planning and training in microtia patients, patient-specific framework is fabricated with precisely assembling, which not only shortens the operation time, but also provides the unexperienced surgeons with a safe and effective training of ear framework fabrication.

BACKGROUNDIntra-cerebral hemorrhage (ICH) is a devastating complication that can result from superficial temporal artery-middle cerebral artery (STA-MCA) bypass in patients undergoing treatment for steno-occlusive cerebrovascular disease (CVD). There is a clinical need to find the possible risk factors to prevent ICH, as it is a significant cause of mortality and morbidity. The aim of the study was to investigate the factors associated with delayed ICH after STA-MCA bypass in patients with steno-occlusive CVDs.

METHODSWe retrospectively analyzed the records of 163 patients seen from 2002 to 2011 with STA-MCA bypass for steno-occlusive cerebrovascular diseases at the Department of Neurosurgery, Xuan Wu Hospital, Beijing. Demographic and clinical data, including age, gender, vascular risk factors, preoperative syndrome, preoperative National Institutes of Health Stroke Scale (NIHSS), ipsilateral ischemic lesions, classification of steno-occlusive CVDs, donor branches of STA, graft patency, postoperative hypertension, and postoperative-increased MCA velocity were recorded and analyzed. Binary Logistic regression served to identify factors associated with delayed ICH after STA-MCA bypass.

RESULTSWe identified 8 (4.9%) patients with delayed ICH after STA-MCA bypass. Patients with hypertension, preoperative stroke, ipsilateral ischemic lesions, postoperative hypertension and postoperative-increased MCA velocity were significantly more prone to experiencing delayed ICH after STA-MCA bypass. Logistic regression analysis shows ipsilateral ischemic lesions, postoperative hypertension, and postoperative-increased MCA velocity remained independent predictors for delayed ICH after STA-MCA bypass.

CONCLUSIONDespite the varied associated factors in patients with steno-occlusive CVDs, ipsilateral ischemic lesions, postoperative hypertension, and postoperative-increased MCA velocity could be associated with delayed ICH after STAMCA bypass.
