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.
Nonsuicidal self-injury (NSSI) is defined as direct, deliberate bodily harm without suicidal intention. Recent studies indicate that prevalence rates are increasing worldwide, in particular under adolescents, indicating a growing public health issue. An impaired ability to regulate negative emotion has been suggested to play a potential role in NSSI behavior. Some recent interventions aim at improving dysfunctional emotion regulation via 'acceptance'. Acceptance represents an objective, nonreactive, nonjudgmental, and calming emotion regulation strategy, partly based on the philosophy of dialectical behavior therapy (DBT) that has been widely used in the clinical treatment of NSSI behaviors. The aim of the present functional magnetic resonance imaging (fMRI) study is to examine whether adolescents with NSSI can implement the acceptance strategy in naturalistic emotional contexts (immersive video clips) and whether they differ from healthy controls in terms of behavioral and neural effects. To this end, the investigators recruit one group of NSSI adolescents (n=40) and one healthy control group (n=40), to compare the subjective emotional experience as well as underlying neural activity as measured by blood oxygenation level-dependent (BOLD) fMRI. The investigators hypothesize that compared to HC, NSSI adolescents will experience stronger negative emotions and show dysregulated neural recruitment of brain systems engaged in emotional reactivity and regulations (e.g. limbic regions, default mode network, and frontal regions).
Safety, tolerability, pharmacokinetics, and pharmacodynamics of JMKX003002 in single and multiple ascending dose randomized，doubled-blind phase 1 study in healthy subjects
The objective of this trial is to evaluate the effectiveness and safeness of continuous Theta Burst Stimulation (cTBS) over the right Inferior Frontal Gyrus (IFG), guided by personalized Brain Functional Sector (pBFS) technology, on language function recovery in patients with post-ischemic stroke aphasia.
The purpose of the study is to determine whether HG004 as gene therapy is safe and effective for the treatment of Leber Congenital Amaurosis caused by mutations in RPE65 gene.
The goal of this clinical trial is to evaluate the response and safety of Cladribine plus Homoharringtonine and Cytarabine regimen (CHA) protocol in de novo acute myeloid leukemia with age <60y. This is a prospective, single-armed mono-center based investigator-initiated trial. About 30 patients who meet the enrollment criteria with be treated with CHA as induction chemotherapy. The complete response rate, survival rate, recurrence rate, and treatment-related mortality with be observed.
The Movement Disorders Society (MDS) Unified Parkinson's Disease Rating Scale (UPDRS) Part III (MDS-UPDRS III) is the primary assessment method for motor symptoms in Parkinson's disease patients. Currently, movement disorder specialists conduct semi-quantitative scoring, which entails limitations such as subjectivity, weak sensitivity, and a limited number of professional physicians. This study, based on machine vision, establishes gold standard labels according to expert scoring. By using machine learning, we develop a machine rating model and compare the model's performance with gold standard rating and general clinical rating to investigate the accuracy of machine vision-based MDS-UPDRS III machine rating.
Post-marketing registration of Infliximab for injection in Chinese pediatric Crohn's disease patients.
The present study aims to establish a " one-sample testing platform " and assess the prevalence of hepatitis C in individuals taking routine physical examination or outpatient visit in mainland China.
Pre-clinical and clinical studies have shown that low-dose radiation therapy has good immune regulatory effects, activates different anti-tumor immune pathways, and regulates tumor stroma to better promote T cell infiltration. Conventional fractionated radiotherapy increases antigen release and presentation, and stimulates immune cells. In theory, the combination of the two can reverse immune resistance. Our study aims to clarify the efficacy and safety of low-dose radiotherapy combined with conventional fractionated radiotherapy in reversing immune therapy resistance for patients with non-small cell lung cancer, including objective response rate (ORR), progression free survival time (PFS), disease control rate (DCR), health-related quality of life assessment (HRQoL), and incidence of adverse events (AEs).
Fracture risk factors have long been identified as key factors in osteoporosis and fragility fractures. The WHO recommended Fracture risk assessmenttool (FRAX) applies clinical risk factors to assess the absolute risk of osteoporotic fractures in each individual. Our preliminary study suggests that FRAX estimates may underestimate the risk of fractures in the Chinese population. In order to optimize the risk prediction model of osteoporotic fractures, a treatment threshold and its optimal cutting point were initially established based on the data of the health management Center of the Second Xiangya Hospital of Central South University.
