Clinical trials

Parkinson's disease (PD) is a neurodegenerative disorder characterized by motor dysfunction. While deep brain stimulation (DBS) is effective, its invasive nature limits its application in early-stage patients. Temporal interference stimulation (TIS) is a novel non-invasive technique that can target deep brain structures like the globus pallidus internus (GPi) by using high-frequency electric fields. This study aims to evaluate the clinical value and underlying mechanisms of TIS in PD patients. The research is divided into two phases: Phase A investigates the immediate regulatory effects of 130 Hz and 40 Hz TIS on brain networks using concurrent fMRI-TIS. Phase B is a randomized, double-blind, sham-controlled trial to assess the long-term efficacy and safety of a 2-week TIS intervention on both motor and non-motor symptoms. The results will help clarify how TIS modulates deep brain networks and its potential as a non-invasive therapy for PD.

In modern society, increasing attention has been devoted to mental health problems among adolescents, with anxiety and depressive disorders being particularly prevalent in this population. Evidence indicates that anxiety not only affects emotional states and daily quality of life but also has significant impacts on physiological health, including blood pressure and heart rate. At present, clinical treatment relies primarily on pharmacological interventions and cognitive behavioral therapy; however, these approaches are associated with limitations such as pronounced side effects and delayed onset of efficacy, which restrict their applicability in adolescents. Music and other structured sounds have been used since ancient times to alleviate negative emotional states such as tension and anxiety. Research has shown that listening to soothing music can reduce sympathetic nervous system activity while enhancing parasympathetic tone, thereby leading to a decrease in heart rate and an increase in heart rate variability (HRV). Owing to its gentle characteristics, low-intensity soothing music is considered effective in relieving stress, regulating emotional states, and exerting beneficial effects on physiological indicators.

This randomized, double-blind, sham-controlled trial aims to evaluate the effect of remote ischemic conditioning (RIC) on cognitive function in patients with cerebral small vessel disease-related mild cognitive impairment. Forty eligible participants will be randomized 1:1 to receive either RIC or sham RIC twice daily for 90 days in addition to standard medical therapy. The primary outcome is the change in Montreal Cognitive Assessment (MoCA) score from baseline to 90 days. Secondary outcomes include changes in white matter hyperintensity burden and diffusion tensor imaging metrics on MRI, EEG functional connectivity, and activities of daily living.

This randomized, single-blind, controlled clinical trial aims to evaluate the efficacy and safety of 40 Hz flicker light stimulation for insomnia in patients with Parkinson's disease (PD). Patients with PD and clinically significant insomnia will be randomly assigned in a 1:1 ratio to receive either 40 Hz flicker light or control light for 30 minutes every night at bedtime for 7 consecutive days, in addition to standard antiparkinsonian treatment. The primary objective is to determine whether 40 Hz flicker light stimulation improves PD-related insomnia as measured by Parkinson's Disease Sleep Scale-2 (PDSS-2). Secondary objectives include evaluating changes in polysomnography-derived sleep parameters, subjective sleep quality, and other non-motor symptoms, as well as assessing the safety and tolerability of the intervention. This registration specifically covers the Parkinson's disease insomnia cohort of a larger, previously approved multi-cohort protocol that also includes healthy volunteers and primary insomnia patients.

This single-center, randomized, single-blind, sham-controlled clinical trial aims to evaluate whether remote ischemic conditioning (RIC) can improve sleep disturbances and other non-motor symptoms in patients with Parkinson's disease (PD). Forty-eight PD patients with insomnia will be randomly assigned in a 1:1 ratio to receive either active RIC (cuff inflation to high pressure) or sham RIC (cuff inflation to low pressure) for 7 consecutive days, in addition to their standard antiparkinsonian medications. Subjective sleep scales, sleep diaries, validated rating scales for motor and non-motor symptoms, and overnight polysomnography will be used to assess treatment effects at baseline, after the 7-day intervention, and during short-term follow-up. The study will also explore potential mechanisms of RIC by combining EEG, functional MRI, retinal optical coherence tomography, and blood biomarkers.

This cohort study involves the dynamic collection of clinical information from adolescent patients with major depressive episodes (including both major depressive disorder and bipolar disorder), encompassing serum parameters, physiological-behavioral signals, neuroimaging data, and neuropsychological scales. The study aims to summarize the comprehensive clinical characteristics of this population, identify new risk factors, and establish multivariate predictive models for treatment response, cognitive and emotional impairments. Furthermore, this research will thoroughly investigate the underlying neural mechanisms linking clinical manifestations and neuroimaging features in major depressive episodes.

This randomized, double-blind, sham-controlled clinical trial aims to evaluate the efficacy and underlying biological mechanisms of HD-tDCS targeting the primary somatosensory cortex in adolescents with bipolar depression. Participants will be randomly assigned to receive either active HD-tDCS or sham stimulation, in addition to routine clinical care. Biological data, including neuroimaging, blood biomarkers, voice and facial features, Photoplethysmography (PPG), Electroencephalography (EEG), and behavioral data, will be collected to explore potential predictors of treatment response.

Mental health is increasingly at the forefront of concerns, especially since the start of COVID-19 pandemic. However, not all individuals under mental subhealth need pharmaceutical treatment. Music Therapy (MT) can make peoples gradually relax via relaxing and soothing music, and regulate individual psychological emotions through the influence of music on individuals' cerebral cortex, hypothalamus and limbic system, further improve the mood of daily tension and anxiety. This study adopted randomized clinical trials design, with two groups of MT group and Waiting group both under mental subhealth. The MT group received music therapy and routine activities, while the Waiting group received music therapy after the therapy of MT group. Data collections were performed by trained, certified, and qualified personnel. The study aims to provide that MT is an effective intervention way to alleviate the mental subhealth state in the future.
