Prospective, open-label, double-dose, performance evaluation of interference effects and component stability of the Intelligent Fingerprinting Drug Screening System

The purpose of this study is to determine how a ketone ester supplement affects brain function, brain blood flow, and brain metabolism in healthy middle-aged and older adults. Ketones are naturally produced by the body during periods of fasting or carbohydrate restriction and ser…

This study is a prospective, randomized, open-label, single-center exploratory trial. A total of 40 newly diagnosed, untreated head and neck cancer patients （stage I-IVa, AJCC 8th edition） will be enrolled and randomly assigned in a 1：1 ratio to either the experimental group or t…

The goal of this observational study is to evaluate the diagnostic efficacy of Confocal Laser Endomicroscopy (CLE) compared to Rapid On-Site Evaluation (ROSE) for ex vivo lung biopsy specimens obtained via bronchoscopy. The main questions it aims to answer are: 1. Does CLE provi…

The goal of this clinical trial is to learn whether an artificial intelligence (AI) tool called FibroX can help primary care providers better diagnose significant liver fibrosis (≥F2) and clinically significant portal hypertension in adults with metabolic dysfunction-associated s…

This is a single armed, Phase 3 study to assess the immunogenicity and safety of the varicella vaccine manufactured by Sinovac. A total of 300 healthy participants aged 1-12 years will be enrolled. All participants will receive a single dose of varicella vaccine manufactured by S…

Schizophrenia is a serious mental illness. Doctors usually diagnose schizophrenia by talking with patients, reviewing symptoms, and using clinical assessment. In early or less typical cases, diagnosis may be difficult. This study will look at whether brain ultrasound information…

Chromocolonoscopy with acetic acid and indigo carmine has shown promise for improving the detection of sessile serrated lesions (SSLs), the precursor lesions responsible for a substantial proportion of interval colorectal cancers. Previous studies have demonstrated its potential …

his study evaluates the clinical utility of an artificial intelligence (AI)-assisted lesion-based urgent referral triage system for ultra-widefield (UWF) retinal images. Unlike disease-classification systems, the AI system identifies predefined vision-threatening retinal finding…

The goal of this clinical study is to learn whether a prehabilitation program can improve recovery after major abdominal surgery in adults with cancer who are receiving treatment before surgery. Prehabilitation is supportive care given before surgery to help patients prepare phys…

Rice-derived recombinant human serum albumin (OsrHSA) possesses an identical primary, secondary, and higher-order structure to plasma-derived human albumin. Through innovative production technology, it fundamentally circumvents the supply limitations and viral contamination risks…

This study will evaluate whether a nutritional intervention is better than another to reduce the incidence of overt hepatic encephalopathy in patients undergoing TIPS insertion for refractory ascites.

Laparoscopic cholecystectomy is a commonly performed surgical procedure. Despite its minimally invasive nature, patients may experience significant postoperative pain, particularly at trocar insertion sites and surgical drain entry sites. Pain originating from the drain site is o…

The goal of this clinical trial is to compare the effects of autogenic drainage and mechanical percussion on lung function, dyspnea, and quality of life in children with cystic fibrosis. The main questions it aims to answer are: * Does autogenic drainage improve lung function m…

This study aims to investigate the effect of cardiopulmonary rehabilitation on cardiorespiratory parameters and functional capacity in patients with pulmonary hypertension.

The goal of this clinical trial is to learn if digital recovery support services (such as smartphone app) help to support alcohol recovery. We focus on a community of Black and African American people with alcohol use disorder (AUD) who receive in-person recovery support services…

The purpose of this study is to assess how well TAR-200 works in real-word by measuring the time taken from the first TAR-200 insertion to worsening of cancer or until the signs and symptoms of cancer occur again (disease-free survival) in participants with non-muscle invasive bl…
