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.
Acute Basilar Artery Occlusion (ABAO), a condition with a high risk of mortality or disability (up to 80%). The safety and efficacy of endovascular thrombectomy (EVT) in ABAO remains uncertain due to inconsistent evidence from random controlled trials (RCTs). Recent studies have explored the use of MRI in ABAO, this study aims to assess the efficacy and safety of EVT and standard medical therapy (SMT) in the treatment of ABAO within 24 hours of onset. It also aims to explore the feasibility and prognostic value of MRI-based assessment of ABAO infarction using AI image analysis software.
Establish echocardiographic normal reference values of Chinese Han adults based on artificial intelligence.
- To quantitatively analyze the total radioactivity (TRA) in excrement after a single oral dose of [14C] D-1553 in healthy subjects, and obtain radioactivity recovery and primary excretion pathways in humans; - To obtain radioactive metabolite profiles of human plasma, urine and feces , identify major metabolites of D-1553 and determine the major metabolic pathways and elimination pathways; - To quantitatively analyze the TRA in whole blood and plasma and obtain PK parameters of plasma TRA and investigate whole blood/plasma ratio for TRA.
Currently there are very few studies using wide-body detectors for 4DCT to determine lung tumor volume and comparing them with conventional detector 4DCT images, and no prospective clinical trials comparing 4DCT images from different width detectors have been queried, therefore, in this study, we will prospectively explore in a body model and patients: 1) the degree of artifacts, tumor volume, and radiation dose of the 4DCT scans performed by different width detectors. differences, and scanning radiation dose. (ii) Whether there are differences in different tumor ITV outlining modalities on 4DCT with different detector widths.
The goal of this mutli-center observational study is toinvestigate the impact of primary tumor resection (PTR) on the long-term survival of patients with non-small-cell lung cancer (NSCLC) and dry pleural dissemination (DPD). The main question it aims to answer is: whether primary tumor resection improve long-term survival of NSCLC patients with dry pleural dissemination.
The goal of this clinical trial is to compare the analgesic effect of sufentanil and ibuprofen and the incidence of vomiting, and to choose better postoperative analgesic drugs for motion sickness patients.in describe participant population. The main questions it aims to answer are: - Whether this anesthesia method can meet the analgesic needs of gynecological laparoscopic surgery. - Whether this anesthesia method can reduce the incidence of nausea and vomiting in patients with motion sickness after gynecological laparoscopic surgery. Participants will use target-controlled infusion anesthesia combined with 0.8g ibuprofen injection. Researchers will compare with use of target-controlled infusion combined with sufentanil to see if the incidence of nausea and vomiting is higher.
Most hepatocellular carcinoma (HCC) are found in the intermediate or advanced stage. The patients lose the opportunity of curative surgical resection. In clinical practice, unresectable HCC is often encountered with large tumor lesions and insufficient remaining liver volume. It is expected that the benefit of direct surgical resection will not exceed that of non-surgical treatment if the tumor is limited in scope but with unclear boundaries, surrounding small foci, or adjacent to important vascular structures, or combined with secondary or higher portal vein tumor thrombus. These patients account for a significant proportion of unresectable HCC, but have the potential for surgical resection. If the investigators can make full use of the existing HCC treatment, the patients hope to obtain radical surgical resection opportunities and better long-term survival after tumor shrinkage and tumor necrosis boundary becomes clear. Transcatheter arterial chemoembolization (TACE) has been the standard arterial treatment for advanced HCC. Tyrosine kinase Inhibitor is the first-line treatment for hepatocellular carcinoma. Tislelizumab is an immune checkpoint inhibitor and a first-line treatment for HCC. This study investigated the efficacy and safety of TACE combined with Tyrosine Kinase Inhibitors and tislelizumab in the treatment of unresectable HCC.
The goal of this clinical trial is to about in Patients With Advanced Solid Tumors. The main question[s] it aims to answer are: - question 1:Evaluating the tolerability of BH002 injection in Chinese patients with advanced solid tumors - question 2:Obtain the pharmacokinetic (PK) characteristics of BH002 injection in Chinese patients with advanced solid tumors
The goal of this retrospective control study is to learn about the effects of Mindfulness Based Stress Reduction (MBSR) intervention in military medical students' resilience, post-traumatic stress disorder symptoms (PTSD) and posttruamatic growth (PTG) etc. The main questions are aims to answer: 1. Would MBSR intervention improve psychological resilience, mindful attention awareness, satisfaction with life, and post-traumatic growth in military medical students？ 2. Would MBSR intervention reduce anxiety, depression, and PTSD symptoms in military medical students？ 3. Would the effects of MBSR intervention persist for at least one month in military medical students？ Participants in the intervention group will complete 8-week of MBSR training while those in the control group will not. Researchers will compare resilience, mindful attention awareness, satisfaction with life, and post-traumatic growth, etc. between the two groups.
To evaluate the detection of hCG in the early pregnancy urine samples by Human chorionic gonadotropin (HCG) test system.
