This research aims to verify the accuracy, stability, and clinical usefulness of artificial intelligence (AI) algorithms for measuring heart function through echocardiography. The study involves collaboration with multiple medical centers and focuses on comparing AI measurements with those done manually by physicians of different experience levels. It also explores whether AI can reduce the time needed for echocardiogram analysis and improve clinical workflows, while assessing AI's performance in complex heart conditions such as cardiomyopathy and valve disease. The study collects echocardiographic data using Mindray ultrasonic machines, with AI and physicians at each center measuring key heart parameters including left and right ventricular size and function. AI and intermediate doctors complete measurements within one day of data collection, while senior physicians at the main research unit finalize their assessments within one month. The goal is to establish a standardized reference system for AI in ultrasound measurement and promote its use across various medical institutions. Participants aged 18 to 80 years with specific heart conditions or normal hearts are involved. Researchers measure heart chamber sizes and functions through echocardiography, comparing AI and physician results for consistency and accuracy. The study also monitors how AI-assisted measurements could optimize diagnosis time and medical resource use. The total duration of participant involvement depends on data collection and measurement timelines, with ongoing analysis to support AI's clinical application in cardiovascular care.

Researchers are evaluating YL202 in a multicenter, open-label phase II study conducted in China. The study focuses on patients with advanced solid tumors, including non-small cell lung cancer (NSCLC), breast cancer, head and neck squamous cell carcinoma (HNSCC), colorectal cancer, HER2-positive gastric cancer, cervical cancer, ovarian cancer, and others. The purpose is to assess the effectiveness, safety, and how the body processes (pharmacokinetics) YL202 in these patients. Participants will receive YL202 through intravenous infusion over approximately 60 minutes. The study treatment involves administering YL202 to selected patients with advanced solid tumors. The trial aims to determine the recommended dose for future clinical studies and to observe treatment response according to established evaluation criteria (RECIST v1.1). This study is expected to last about 36 months. Throughout the study, participants will undergo various assessments, including tumor measurements to evaluate treatment response, safety monitoring, and pharmacokinetic sampling to understand drug behavior in the body. Researchers will also review patients' organ and bone marrow function before treatment begins. The study requires participants to comply with scheduled visits and procedures to ensure thorough monitoring of treatment effects and safety over the trial period.

Researchers are evaluating whether the medicine tenecteplase helps adults recover from an acute ischemic stroke when given more than 4.5 hours after they were last seen well. This study focuses on people who had a stroke caused by a clot blocking blood flow in the brain and who have imaging showing brain tissue that can still be saved. Participants should not be planning to receive a procedure to remove the clot and must have a pre-stroke disability level of 0 or 1 on the modified Rankin Scale. Participants are randomly placed into two groups. One group receives a single injection of tenecteplase into a vein, while the other group receives standard medical care. The study includes adults aged 18 and over who had an acute stroke or woke up with stroke symptoms more than 4.5 hours ago. Imaging with MRI or CT is used to confirm eligibility. The study lasts about three months, starting with a hospital stay of about one week. During the study, participants have seven clinical examinations or visits to monitor their recovery and health. The last two visits may be done from home to allow remote assessments. Researchers use the modified Rankin Scale to measure disability or dependence in daily activities at 90 days after treatment. They also monitor for any side effects or health changes to compare the effects of tenecteplase against standard care.

Stroke is the second leading cause of death worldwide, with ischemic stroke being the most common type. The current best treatment for acute ischemic stroke is intravenous thrombolysis using recombinant tissue plasminogen activator (rt-PA) given within 4.5 hours of symptom onset. However, some patients experience stroke progression or early blood vessel reocclusion after thrombolysis, which worsens neurological function and outcomes. This is believed to be caused by increased platelet activation after thrombolysis, which peaks within the first 2 hours. This clinical trial is testing whether starting oral aspirin early after intravenous thrombolysis can improve functional outcomes without causing more bleeding problems. Patients are randomly assigned to receive either 300 mg aspirin tablets or matching placebo tablets as soon as possible after enrollment. If swallowing is difficult, tablets can be crushed and given through a nasogastric tube. Both groups receive best medical management according to guidelines. The study is a Phase 3, multicenter, randomized, placebo-controlled trial. Participants will be followed for 90 days after stroke to measure their functional recovery using the modified Rankin scale (mRS). Researchers will check if patients have a good outcome defined as an mRS score of 0 or 1 at 90 days. During the study, patients undergo assessments including neurological exams and imaging to confirm eligibility and monitor safety. The trial aims to determine if early aspirin treatment after thrombolysis is safe and can help prevent neurological decline and improve recovery.

Researchers are evaluating the efficacy and safety of Yangxinshi tablets in patients with coronary heart disease complicated by cardiac dysfunction. This Phase 4 randomized controlled trial aims to determine whether adding Yangxinshi tablets to conventional treatment can reduce ischemic or heart failure-related clinical events, improve exercise tolerance, and enhance quality of life and mental health in these patients. The study includes 2708 patients aged 40 to 80 years with specific heart conditions and symptoms. Participants are randomly divided into two groups: one group receives conventional treatment plus Yangxinshi tablets (3 tablets, three times daily), while the control group receives only conventional treatment without additional tablets. Conventional treatment includes drugs such as aspirin, beta-blockers, statins, and others aimed at improving outcomes and relieving symptoms. The treatment continues until the expected number of endpoint events occurs or the study ends. During the study, participants are monitored for ischemic events or heart failure-related clinical events, including death, stroke, myocardial infarction, and hospital readmissions. The average follow-up period is about three years. Researchers assess exercise tolerance, quality of life, and mental health, while monitoring safety and overall health status throughout the study.
