There are about 36818 clinical studies being (or have been) conducted in China. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The technological advance of magnetic resonance-guided focused ultrasound (MRgFUS) has once again brought lesion therapy back to the clinical frontline for the treatment of movement disorder. Thus far, the safety of MRgFUS has been widely proven and has just been made available in China in late 2020. We attempted to analyze the neuroplasticity characteristics and altered neural circuit activity in patients subjected with MRgFUS thalamotomy via Multiple MR Imaging study, and to explore potential biomarkers that could be used to predict the treatment outcome.
Objective: To investigate the incidence, clinical characteristics and prognosis of acute ischemic and hemorrhagic cerebrovascular disease secondary to the implantation of cardiovascular implantable electronic devices, so as to provide a basis for subsequent treatment strategies and risk factor stratification. Methods: This study intends to retrospectively collect the incidence and case characteristics of acute cerebral infarction, cerebral embolism, transient ischemic attack and cerebral hemorrhage in CIED patients admitted to the First Affiliated Hospital of Xi 'an Jiaotong University and other centers from January 2012 to September 2022. Then, the incidence of poor prognosis and related factors of patients within 3 months were followed up by telephone to provide a basis for subsequent treatment strategy and risk factor stratification.
Sudden deafness is a sudden, unexplained sensorineural hearing loss of ≥20 dBHL in at least two adjacent frequencies within 72 h. It may be accompanied by tinnitus, a sense of ear congestion, vertigo and other Symptoms.Stellate ganglion block increases the blood flow and blood velocity in the inner ear, keeping the body's vegetative, endocrine and immune functions normal.The branches of the facial and linguopharyngeal nerves are connected to the inner ear, and local injection can nourish the nerves and improve local circulation.
The purpose of this study is to analysis the fluorescence image of the breast sentinel lymph node (SLN) using Indocyanine green (ICG). Moreover, to investigate whether an artificial intelligence protocol was suitable for identifying metastatic status of SLN during the surgery, and evaluate the diagnosis consistency of the AI technique and pathological examinations for lymph node with and without metastasis.
The purpose of this study was to evaluate the efficacy of sugemalimab consolidation therapy versus placebo in patients with LS-SCLC who had not progressed following Concurrent or Sequential Chemoradiotherapy.
A phase 2b, multicenter, randomized, double-blind, placebo-controlled study of HTD1801 in adult subjects with non-alcoholic steatohepatitis and liver fibrosis who have type 2 diabetes mellitus or pre-diabetes.
The goal of this observational study is to learn about neuroimage and biomarkers in the Alzheimer's continuum. The main questions it aims to answer are: - How is the neurovascular coupling during AD pathogenesis? - How is the pattern/mapping of alterations in AD biomarkers? Participants will be observed and visit the research center annually to perform multi-modal MRI, PET, neuropsychological tests, and blood tests.
Clinical and animal studies have found that sepsis can lead to a serious imbalance in the gut microecology, a reduction in probiotics, a reduction in short-chain fatty acid, a reduction in bone mass, and an increase in bone destruction, maintaining the stability of microecology can be one of the effective means of bone protection. But at present, the treatment of sepsis with early supplementation of probiotics is still controversial, and dietary fiber intake has significantly changed the composition of the microbiota, it may be a safe and effective method to prevent bone loss in sepsis. Further study on it will provide reliable theoretical basis and intervention target for early, safe and effective prevention of osteoporosis.
The goal of this observational study is to test whether the dynamic changes of CD4+T lymphocytes can predict infections in patients with primary nephrotic syndrome . The main questions it aims to answer are: - whether the dynamic changes of CD4+T lymphocytes can predict infections in patients with primary nephrotic syndrome - effect of different immunosuppressive therapy on the number and function of T lymphocyte subsets in patients with primary nephrotic syndrome Participants will be divided into infection group and non-infection group according to whether they are infected
Streptococcus pneumoniae infections often cause serious health problems, especially in infants and the elderly. Failure to cover all polysaccharide types of vaccines is a greater problem for adults than for children. The purpose of this study was to preliminarily evaluate the safety and immunogenicity of a recombinant pneumococcal protein vaccine applied to adults aged 50 years and older to provide a basis for subsequent clinical trial design.
