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.
This study is a single-center, open-label, and single-dose clinical study to evaluate the mass balance, biotransformation and pharmacokinetics of [14C]RAY1216 in healthy Chinese male participants, revealing the overall pharmacokinetic characteristics of RAY1216.
China's aging population is causing an increase in the number of senior persons undergoing surgery. More and more clinicians are paying attention to the postoperative survival and mental health of elderly surgical patients. Dexmedetomidine (DEX) is an alpha-2 adrenergic agonist that works by inhibiting norepinephrine releasing renaline, which reduces inflammation and thus plays a protective role in the central nervous system. DEX has the potential to prevent and treat postoperative anxiety and depression in elderly patients undergoing non-cardiac surgery. Further exploration of evidence for evidence-based medicine is needed. Based on the above research background, this hypothesis is proposed: in elderly patients undergoing noncardiac surgery, intraoperative DEX is associated with a reduction in short-term postoperative mental disorders and a reduction in long-term postoperative mortality.
The goal of this clinical trial is to learn the effectiveness of remote home-based exercise rehabilitation using mobile Internet technology for patients with pulmonary hypertension，especically providing early and mid-term results of its effectiveness. The main questions it aims to answer are: Dose tele-rehabilitation training improves prognostic function and quality of life in patients with pulmonary hypertension？ Researchers will compare tele-rehabilitation training group to a control group (receive health propaganda and education, and then follow their daily routine after discharge from the hospital) to see if tele-rehabilitation training works to improve prognosis. Participants will: During their stay in the hospital, the patients of tele-rehabilitation training group were accompanied by a rehabilitation trainer and a psychotherapist for a complete cycle of (7 days ± 3 days 1 week/times) standardized training. The scheme of rehabilitation is impedance training. A specialized professional team including cardiologists, rehabilitation trainers, psychotherapists and radiologists were involved. After discharge from the hospital, patients in the rehabilitation group underwent 3-5 weekly daily training sessions and intensive supervision and management by the online community at least once a week. Visit the clinic at the 3rd month of the study. Extended follow-up up to 6 months may be considered if patients are cooperative and could complete the training program in the first 3 months.
1. Integrate pharmacokinetic-pharmacodynamic (PK-PD) modeling and pharmacogenomics techniques to develop a population PK-PD model, aiming to explore monitoring and dose guidance schemes for Direct Oral Anticoagulants (DOACs). 2. Investigate the factors influencing PK-PD of DOACs in the pulmonary embolism population, clarifying the correlation between genotype characteristics and clinical outcomes. 3. Explore the correlation between drug concentrations, coagulation indices, and clinical outcomes of DOACs, defining the indications for DOACs testing and the overall monitoring process.
Accurate preoperative detection of muscle-invasive bladder cancer remains a clinical challenge. The investigators aimed to develop and validate a knowledge-guided causal diagnostic network for the detection of muscle-invasive bladder cancer with multiparametric magnetic resonance imaging(MRI).
Explore the impact of the first-line application of Toripalimab with or without Lenvatinib or chemotherapy, on the survival, disease progression, and drug safety of patients with advanced biliary tract cancers
The goal of this clinical trial is to compare the cancer detection rates of MRI artificial intelligence-guided cTB (AI-cTB) and routine cTB, and explore the added value of using AI for the guidance of cTB. The main questions it aims to answer are: Does AI-cTB promote the accurate diagnosis and treatment of prostate cancer? What's the value of prostate MRI artificial intelligence assistant diagnosis system in developing the best scheme of prostate biopsy? What's the value of prostate MRI artificial intelligence assistant diagnosis system in predicting the pathological results of prostate targeted biopsy? Researchers will compare the cancer detection rates of AI-cTB and routine cTB to explore the added value of using AI for the guidance of cTB. Participants will: Receive AI-cTB or routine cTB.
The goal of this multi-center observational clinical trial is to investigate the genetic risk factors of patients with premature CAD and none traditional CAD risk factors through a multi-omics approach. The main questions it aims to answer are: - Genetic risk factors & metabolic fingerprints of patients with premature CAD and none traditional CAD risk factors remain unknown. - How to optimize current primary prevention strategy for this rare CAD subgroup？
This study includes two cohorts, cohort A is for non-squamous NSCLC and cohort B is for squamous NSCLC.
