Researchers are conducting a multi-center clinical study to assess artificial intelligence AI algorithms for measuring heart function and size using echocardiography. The study aims to compare AI measurements with those of physicians at different experience levels, evaluate the accuracy and stability of AI, and explore its use in complex heart conditions like cardiomyopathy, valve disease, and coronary heart disease. The goal is to improve diagnostic consistency and clinical workflows across medical centers. The study involves measuring cardiac chamber size and function in 1600 participants using AI, senior physicians, and intermediate physicians. All measurements are made with Mindray ultrasonic machines. AI and intermediate physician results are completed within one day after data collection, while senior physician results are completed within one month. The study will establish a standardized reference system for AI-assisted echocardiographic measurements and evaluate AIs performance in special cases. Participants will undergo echocardiographic scans with measurements of left and right ventricular size and function, Doppler ultrasound indicators, and valve annulus displacements. Researchers will analyze data to compare AI and physician measurements, assess measurement deviations, and evaluate AIs efficiency in reducing analysis time. The study will run until July 2026, with ongoing data collection and analysis across multiple centers, aiming to promote wider clinical application of AI technology for cardiovascular disease diagnosis.

Researchers are evaluating YL202 in a multicenter, open-label phase II study in China to understand its effects on patients with advanced solid tumors such as non-small cell lung cancer, breast cancer, head and neck squamous cell carcinoma, colorectal cancer, HER2-positive gastric cancer, cervical cancer, and ovarian cancer. The study aims to assess the efficacy, safety, and pharmacokinetic characteristics of YL202 in these patients. Patients will receive YL202 as an intravenous infusion, delivered as a lyophilized powder at a dose of 200 mg per vial. The treatment is given once every three weeks for locally advanced or metastatic tumors, with separate groups for different cancer types including NSCLC, breast cancer, HNSCC, and other locally advanced cancers. Each infusion lasts approximately 60 minutes. Participants will undergo evaluations including tumor response assessments according to RECIST v1.1 criteria, safety monitoring for adverse events, and pharmacokinetic analyses over approximately 36 months. Researchers will measure outcomes such as overall response rate, progression-free survival, duration of response, and overall survival. Tumor tissue samples and other clinical data will also be collected to analyze treatment effects and biomarker relationships. Participants are expected to comply with scheduled visits and procedures throughout the study.

This trial is for adults who have had an acute ischemic stroke caused by a blood clot blocking a brain vessel. It focuses on people whose stroke occurred or was discovered more than 4.5 hours ago, including those who woke up with stroke symptoms. The study aims to find out if the medicine tenecteplase helps recovery when given after this 4.5-hour window, compared to standard medical care. Tenecteplase is already used within 4.5 hours after stroke onset, but this study tests its effect when given later. Participants are randomly assigned to one of two groups one receives a single injection of tenecteplase into a vein, and the other receives the usual standard treatment. Both groups have an equal chance of receiving either treatment. The study lasts about three months, starting with approximately one week of hospital stay. During the study, participants have seven clinical examinations or visits, with the final two visits conducted remotely from home to allow for easier participation. Throughout the study, doctors regularly assess participants recovery using a scale that measures disability and dependence in daily activities. They also monitor overall health and record any side effects. The main outcome measured is the level of recovery 90 days after treatment, comparing the two groups. This includes neurological improvement, bleeding events, and survival over the study period.

Acute ischemic stroke is a leading cause of death worldwide, and intravenous thrombolysis with recombinant tissue plasminogen activator rt-PA within 4.5 hours of symptom onset is the most effective treatment currently available. However, some patients experience stroke progression and early reocclusion after thrombolysis, which can worsen neurological outcomes. This trial evaluates whether early antiplatelet therapy with oral aspirin, given soon after thrombolysis, can improve recovery without increasing bleeding risks. The study randomly assigns patients to receive either early oral aspirin within 3 hours of starting intravenous thrombolysis or a placebo, alongside the best medical care based on current guidelines. Aspirin is administered as a 300 mg dose, either chewed or given via nasogastric tube if swallowing is difficult. The trial includes a control group receiving placebo under similar conditions to compare outcomes. This is a Phase 3, multicenter, quadruple-blind, randomized clinical trial. During the study, participants will be closely monitored for neurological status and functional recovery using the modified Rankin scale at 30 and 90 days after stroke, as well as other assessments like NIH Stroke Scale scores within the first week. Researchers will track early neurological changes and safety outcomes such as intracranial hemorrhage. Follow-up will include evaluations at multiple time points up to 90 days post-stroke to determine the effects of early antiplatelet treatment on stroke recovery.

Researchers are evaluating the safety and effectiveness of Yangxinshi tablets in patients with coronary heart disease combined with cardiac dysfunction. This study aims to determine if adding Yangxinshi tablets to standard treatment can reduce heart-related events, enhance exercise capacity, and improve quality of life and mental health. The trial includes 2708 patients and is a Phase 4 randomized controlled study sponsored by SPH Qingdao Growful Pharmaceutical Co., Ltd. Participants are randomly assigned to one of two groups one group receives conventional treatment plus Yangxinshi tablets 3 tablets taken orally three times a day, while the control group receives conventional treatment alone. Conventional treatment includes drugs such as aspirin, beta-blockers, statins, and others for symptom relief and improving heart outcomes. The treatment continues until a set number of heart-related events occur or the study ends. Throughout the study, participants undergo regular assessments including measurements of heart events, exercise tolerance, heart function tests, blood markers, and mental health questionnaires over an average of three years. Additional evaluations at 24 and 48 weeks include depression and anxiety scales, echocardiography, and exercise testing. The research team closely monitors safety, quality of life, and heart function throughout the study period.
