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.
In patients with complex coronary artery disease (CAD), determining the optimal revascularization strategy (percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) remains a challenge. These high-risk patients pose an extreme surgical risk. However, with the development of new interventional techniques and materials, PCI is a good alternative to CABG and is referred to as complex high-risk indicated PCI (CHIP). During CHIP, hemodynamics can deteriorate because of temporary complete coronary occlusion or profound myocardial ischemia. This could result in loss of cardiac output and hemodynamics collapse. Mechanical support during CHIP facilitates native cardiac function by achieving a stable hemodynamic state to withstand repetitive derangements such as ischemia caused by prolonged and repeated balloon inflations, and resume original cardiac function immediately postprocedure or shortly thereafter. There are several mechanical circulatory support (MCS) systems available, i.e., intra-aortic balloon counterpulsation (IABP), Impella, TandemHeart, and veno-arterial extracorporeal membrane oxygenation (VA-ECMO). These MCS have been widely studied in patients with acute myocardial infarction (MI) complicated by cardiogenic shock and showed conflicting results. However, studies regarding the use of MCS in the setting of CHIP are much less abundant and no randomized study has compared Impella with VA-ECMO in CHIP patients. The aim of the study is to evaluate the effectiveness of interventional ventricular assist system (CorVad) compared to the venoarterial extracorporeal membrane oxygenation (VA-ECMO) system in providing circulatory support for complicated and high-risk patient with indications for PCI.
The objective of this study is to evaluate the safety and pharmacokinetic profiles of HHT201 in healthy subjects.
This is an investigator-initiated trial to evaluate the safety and efficacy of anti-CD19-CD3E-CAR-T cells in the relapse or refractory autoimmune diseases.
Ultrasound (US) is a more cost-effective, accessible, and available imaging technique to assess anterior talofibular ligament (ATFL) injuries compared with magnetic resonance imaging (MRI). However, challenges in using this technique and increasing demand on qualified musculoskeletal (MSK) radiologists delay the diagnosis. The investigators have already developed a deep convolutional network (DCNN) model that automates detailed classification of ATFL injuries. The investigators hope to use the DCNN in real-world clinical setting to test its diagnostic accuracy.
Ultrasound (US) is a more cost-effective, accessible, and available imaging technique to assess anterior talofibular ligament (ATFL) injuries compared with magnetic resonance imaging (MRI). However, challenges in using this technique and increasing demand on qualified musculoskeletal (MSK) radiologists delay the diagnosis. Using datasets from multiple clinical centers, the investigators aimed to develop and validate a deep convolutional network (DCNN) model that automates classification of ATFL injuries using US images with the goal of providing interpretable assistance to radiologists and facilitating a more accurate diagnosis of ATFL injuries. The investigators collected US images of ATFL injuries which had arthroscopic surgery results as reference standard form 13 hospitals across China;Then the investigators divided the images into training dataset, internal validation dataset, and external validation dataset in a ratio of 8:1:1; the investigators chose an optimal DCNN model to test its diagnostic performance of the model, including the diagnostic accuracy, sensitivity, specificity, F1 score. At last, the investigators compared the diagnostic performance of the model with 12 radiologists at different levels of expertise.
This is a randomized, multi-center, split-hand, subject-blinded study comparing pain, safety and effectiveness of Restylane Skinboosters Vital Lidocaine and Restylane Vital without lidocaine for improving appearance of the dorsal hands in Chinese subjects.
This study aimed to provide normal reference values of surface electromyography (sEMG) and mandibular kinematics in Chinese young adults, compare the sex differences and assess the diagnosis value of these indices.
The goal of this observational study is to evaluate the impact of deep learning image reconstruction on the image quality and diagnostic performance of double low-dose CTA. The main question it aims to answer is to explore the feasibility of deep learning image reconstruction in double low-dose CTA.
