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 goal of this study is to quantitatively assess renal microcirculation changes by contrast-enhanced ultrasound and to obtain systemic hemodynamic information by ultrasound Doppler at the same time, to analyze the relationship between renal microcirculation changes and systemic hemodynamic changes, and to explore its predictive value in renal function recovery in patients with critical acute kidney injury. The main questions it aims to answer are: 1. To explore the quantitative parameters of contrast-enhanced ultrasound which can reflect the changes of renal microcirculation. 2. To explore the relationship between renal microcirculation and systemic hemodynamics. 3. To explore the value of renal microflow changes quantitatively evaluated by contrast-enhanced ultrasound in predicting renal function recovery.
The goal of this clinical trial is to learn about effectiveness and safety of washing microbiota transplantation in diabetic gastrointestinal motility disorders participant population. The main questions it aims to answer are: - The risk factors of diabetic gastrointestinal motility disorders in routine clinical data or biochemical tests. - The composition of gut microbiota in diabetic gastrointestinal motility disorders patients and potential pathogenic bacteria. - The efficacy of washing microbiota transplantation in the clinical treatment of diabetic gastrointestinal motility disorders patients and potential factors that may influence treatment outcomes. - The potential mechanisms of washing microbiota transplantation in treating diabetic gastrointestinal motility disorders patients. Participants will be collected fasting venous blood and random stool samples before treatment and at week 12 post-treatment, conducting scale assessments before treatment and at weeks 1, 4, and 12 post-treatment.
This study is prospective, single-center, single-arm objective performance criteria. This trial will be conducted with a total of 47 subjects enrolled. All of subjects will be treated with radiation therapy using the medical device Varian ProBeam Proton Therapy System (ProBeam), aim to compare the data with objective performance criteria (OPC) to evaluate the effectiveness and safety of ProBeam radiotherapy system for oncology patients, providing a clinical basis for the medical device registration.
Vonoprazan and high-dose amoxicillin dual therapy was used as a control group to evaluate the clinical effiency and safety of Banxiaxiexin decoction combined with vonoprazan and high-dose amoxicillin dual therapy in the treatment of helicobacter pylori infection complicated with functional dyspepsia,through a randomized controlled trail.
The goal of this randomized controlled trial is to test the effectiveness of a resilience intervention and an adherence intervention in improving health-related quality of life (HRQoL) among perinatally infected HIV positive children and their HIV positive mothers in China. The main questions it aims to answer are: 1. Whether baseline resilience and treatment adherence are associated with the HRQoL; 2. Whether the resilience intervention will improve the mediators associated with intervention sessions, such as positive coping and social support, the proximal outcome of resilience factors, the distal outcome of HRQoL, and dyadic level outcomes such as dyadic coping; 3. Whether the adherence intervention will improve the mediators associated with intervention sessions, such as adherence information and behavioral skills, the proximal outcome of self-reported adherence, the distal outcome of HRQoL, and dyadic level outcomes such as dyadic coping; 4. Whether the enhanced mediators (e.g., positive coping and social support) associated with the resilience-intervention sessions at the end of the intervention will transmit the effect of the resilience intervention on the increases in resilience factors during follow-ups; 5. Whether the improved mediators (e.g., adherence information and behavioral skills) associated with the adherence-intervention sessions at the completion of the intervention will transmit the effect of the adherence intervention on the increases in adherence in follow-ups. Participating mother-child dyads in the two intervention arms will receive two sessions of dyadic intervention. Researchers will compare the above-described outcomes between participants in the two intervention arms and the control arm (treatment as usual) to see the effectiveness of the interventions.
This study is an open-label, single-arm, dose escalation and dose expansion study to evaluate the safety, maximum tolerated dose, pharmacokinetic characteristics of allogeneic CD19-CAR-DNT cells (RJMty19) after infusion, and preliminary efficacy in systemic lupus erythematosus (SLE) subjects.
Chronic obstructive pulmonary disease (COPD) is the most common chronic tract disease and the third leading cause of death worldwide. The treatment effect of COPD is poor, and the disease is progressive, resulting in a serious disease burden. The key reason is that early recognition is difficult and the early pathophysiological mechanism is unclear, which leads to the difficulty of early intervention.PRISm is likely to be the precursor stage of COPD, which may provide an important research object for the study of pathophysiological characteristics, inflammation and immunomodulatory mechanisms of early COPD, and may also become a new entry point for early intervention of COPD. This study attempts to establish a PRISm prospective cohort，and collects blood, EBC and urine for analysis of inflammatory factors, metabolomics, proteomics and microbiome, and performs chest HRCT to obtain imaging indicators, and conducts 3-year dynamic follow-up observation to study the evolution characteristics of pulmonary function and the incidence of COPD in the PRISm cohort. To compare the differences in imaging, inflammatory factors, metabolomics, proteomics and microbiome among the three PRISm groups, and establish a risk prediction model for progression to COPD through PRISm. It lays a foundation for understanding the characteristics of COPD at an earlier stage and exploring new early warning indicators.
This is an open-label, phase II study evaluating the efficacy and safety of SHR-A1811 alone or in combination with Adebrelimab in Stage II-III ER Positive/HER2 Low Breast Cancer. Subjects will receive the neoadjuvant therapy of SHR-A1811 alone or in combination with Adebrelimab for six cycles, and then undergo surgery within 4 weeks after neoadjuvant therapy. Efficacy will be assessed every 2 cycles.
This is a randomized controlled trial to explore the efficacy and safety of washed microbiota transplantation (WMT) for diabetic gastroparesis (DGP) patients.
The investigators explored the safety and activity of weekly irinotecan liposomes in patients with relapsed and metastatic Ewing Sarcoma.
