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.
Based on the data from the anesthesia record electronic system, patient safety incident (PSI) electronic reporting system and related PSI retrospective cohort in the past 10 years, this project intends to carry out structured and consistent (real world data)RWD processing, and conduct (real world evidence)RWE research related to perioperative safety and quality control in order to characterize the epidemiology of perioperative PSIs, explore the related factors, and construct a prediction model, and on the basis of which to construct a standardized platform for reporting and analysis of perioperative PSIs based on RWD. On this basis, a standardized platform for PSI reporting and analysis was constructed based on RWD.
Liwen procedure is generally safe and effective in treating hypertrophic cardiomyopathy, but a small proportion of patients have complications after the operation. The goal of this observational study is to explore the incidence of postoperative complications of the Liwen procedure in hypertrophic cardiomyopathy patients underwent Liwen procedure in Xijing Hospital. The main question it aims to answer are: - What is the incidence of complications in HCM patients underwent Liwen Procedure during postoperative hospitalization and a short-term follow-up period? - What is the relevant factors of complications in HCM patients who underwent Liwen Procedure during postoperative hospitalization and short-term follow-up period? Can the complications of surgical patients during postoperative hospitalization be predicted? Participants have been evaluated using a variety of medical examinations before they underwent Liwen Procedure. Variants collected from medical examination and case history were used to analyze the association with each postoperative complication.
The purpose of this study is to evaluate the efficacy, safety, and tolerability of BMS-986278 in participants with Idiopathic Pulmonary Fibrosis.
Percutaneous radiofrequency ablation is a commonly treatment for patients with liver cancer that cannot be surgically resected. During the procedure, patients need to keep awake and cooperate with the procedure, including deep breath and hold breath. However, intolerable pain generated during puncture and radiofrequency heating may cause body movements and interfere the procedure. Oxycodone is frequently used for analgesia but still insufficient. A recent study showed that dexmedetomidine-esketamine combination improves analgesia without increasing adverse events. After stopping infusion, the analgesic/sleep-promoting effects of dexmedetomidine-esketamine seemed to last for up to 24 hours. The investigators hypothesize that dexmedetomidine-esketamine combination as a supplement to oxycodone will improve sedation and analgesia in patients undergoing radiofrequency liver ablation of the liver.

To investigate the relative bioavailability of HSK7653(25mg) given as formulation A versus formulation B. To investigate safety and pharmacodynamics of two doses of HSK7653 in healthy male subjects.
At present, radical resection ± preoperative neoadjuvant chemotherapy for colorectal cancer is still the standard comprehensive treatment. In recent years, immunotherapy of PD-1 monoclonal antibody has a significant effect in the second-line/first-line treatment of dMMR/MSI-H advanced colorectal cancer and the neoadjuvant treatment of early colorectal cancer. Synchronous multiple primary colorectal cancer (sMPCC) is a relatively rare type of colorectal cancer (CRC) that refers to the simultaneous occurrence of 2 or more independent primary malignancies in the colon or rectum. The recent large-scale, single-center retrospective study of the investigator showed that compared with single primary colorectal cancer (SPCRC)patients, the incidence of dMMR/MSI-H was significantly higher in sMPCC patients. Besides, a certain proportion of sMPCC patients could both have MSI and MSS tumors at the same time. There is no standard regimen for this patients so far. This study intends to treat the MSI-H/MSS (dMMR/pMMR) mixed sMPCC patients with combination of mFOLFOX6+PD-1 monoclonal antibody neoadjuvant therapy, and treat the all-MSI-H (dMMR) sMPCC patients with single-drug PD-1 monoclonal antibody neoadjuvant therapy. Given the current gaps in the guideline, the investigator intends to take the lead in carrying out this open, multi-center, prospective clinical phase II study. This study might provide a clinical evidence for individual treatment of sMPCC patients, in preserving the functions and organs to the greatest extent.
The goal of this observational study is to investigate ventricular repolarization utilizing Tp-e intervals and Tp-e/QT ratios in patients with DM. The main questions it aims to answer are: - 1.Exploring the changes in ventricular repolarization parameters (QT interval, QTc interval, QTd, Tp-e interval, Tp-e/QT ratio) in patients with dermatomyositis, providing quantifiable indicators for early detection of arrhythmia in dermatomyositis patients; - 2.Exploring the role of inflammation in ventricular repolarization in DM patients, providing a basis for in-depth research on the diagnosis and prevention of arrhythmia in DM patients.
Evaluation of the safety and effectiveness of disposable ultrasound soft tissue cutting and hemostasis equipment for coagulating 5-7mm blood vessels with ultrasound scalpel tips
1. To retrospectively explore the feasibility of multi-dimensional heterogeneity imaging features of MRI in predicting the status of key gene mutations in high-grade gliomas; 2. To prospectively explore the correlation between multi-dimensional heterogeneous MRI image features and prognosis of high-grade glioma patients.
At present, no drug therapy has been proven to delay the progression of Parkinson's disease (PD). rTMS, as a non-invasive neuromodulation method, can regulate Slow-wave sleep (SWS). SWS is recognized closely related to neurodegeneration. However, there has been no clinical studies on if rTMS could delay the progression of PD by regulating SWS. The main purpose of this study is to explore the changes of SWS in non-rapid eye movement (NREM) sleep period in PD patients by using rTMS, and the relationship with potential improvements of SWS and motor symptom delay. The study aims to find a potential new treatment strategy to delay the neurodegenerative process in PD patients by modulating SWS by rTMS.
