Clinical trials

This study investigates the level and distribution of suicide risk and learned suicide ability of patients with mood disorders, investigates the related risk factors of suicide and suicide ability formation of patients with mood disorders from multiple dimensions (biological, psychological, social and clinical perspectives) and clarifies their importance, forms a list of suicide risk factors, and establishes a prediction model of learned suicide ability formation. Upon enrollment, participants will undergo comprehensive assessments including blood and urine sample collection and scale evaluation. The collection of scientific blood and urine is mainly used for the exploration of molecular mechanism of disease occurrence and development, the discovery and verification of biomarkers. Scale evaluation includes: Beck Scale for Suicide Ideation , Columbia Suicide Severity Rating Scale,, Hamilton Depression Rating Scale , Hamilton Anxiety Rating Scale, PHQ-9, GAD-7, Personal and Social Function Scale , Schihan Disability Scale , Emotional Adjustment Difficulty Scale , Acquired Capability for Suicide Scale, Interpersonal Needs Questionnaire , Ottawa Self-Injury Scale, Chinese version of Stress Perception Scale and Beck Hopelessness Scale . Follow-up was carried out for 3 months, including whether suicide/self-injury occurred, current status, and some baseline questionnaires (such as BSI-CV, GAD-7, PHQ-9, HAMD-17,HAMA, etc.).

The aim of this study is to evaluate the feasibility and efficacy of deep transcranial magnetic stimulation (dTMS) as an add-on treatment for bipolar depression. Meanwhile, we aim to evaluate the effect of dTMS on cognitive function of bipolar depressive patients. We hypothesize dTMS would improve depressive symptoms and cognitive function in bipolar disorder.

Schizophrenia is a complex mental disorder characterized by a range of symptoms, including negative symptoms and cognitive impairments. Recent research has indicated the potential benefits of targeting mitochondrial dysfunction, oxidative stress, and inflammatory responses in alleviating symptoms of schizophrenia. However, the results remain inconsistent across various studies. This study aims to evaluate the efficacy of Pyrroloquinoline quinone (PQQ) in reducing negative symptoms and improving cognitive function in patients with chronic schizophrenia. The investigation will focus on changes in severity scores from baseline to endpoint, as well as during an eight-week follow-up period. A double-blind, randomized controlled trial will be conducted involving participants diagnosed with chronic schizophrenia. Participants will be randomly assigned to receive either PQQ or a matched placebo. Data will be collected through questionnaires and neuroimaging techniques, including resting-state scans and multimodal tasks to assess functional connectivity and activation in target brain regions. Statistical analyses will include descriptive statistics, voxel-by-voxel multiple regression, and linear mixed models to account for repeated measurements. Additionally, potential moderating effects of demographic factors such as age and gender will be examined using ANCOVAs. The study will also monitor adverse events and ensure participant safety through a rigorous reporting and unblinding procedure. It is hope to provide insights into the therapeutic potential of PQQ in managing schizophrenia symptoms, contributing to the development of more effective treatment strategies for this challenging condition.

Schizophrenia is a severe mental illness characterised by positive symptoms, negative symptoms, and cognitive symptoms. In recent years, an increasing number of doctors and scholars have focused on cognitive symptoms; however, the mechanisms underlying cognitive impairment remain unclear. Recently, exosome research methods have provided new avenues for investigation. This study applies exosome research methods to first-episode, drug-naive schizophrenia patients to explore gene expression changes associated with cognitive impairment and gain a deeper understanding of the mechanisms underlying cognitive impairment. By integrating basic research with clinical findings, we aim to further investigate the molecular mechanisms underlying cognitive impairment in schizophrenia patients, identify potential intervention targets, and provide insights for future drug development.

This study is a randomized controlled trial with a duration of 12 weeks (4 weeks of intervention + 8 weeks of follow-up). The participants are patients with treatment-resistant depression (TRD) and high inflammatory activity (n=52). The study aims to clarify the effectiveness of 15mA, 77.5Hz transcranial alternating current stimulation (tACS) in treating TRD with high inflammatory activity by comparing the changes in depressive symptoms and biological markers after active tACS stimulation versus sham stimulation. Additionally, the study seeks to explore potential underlying mechanisms of action.
