Clinical trials

Atrial fibrillation is a common heart rhythm disorder. Some patients may have early episodes of atrial arrhythmia after pulsed field ablation, and inflammation after the procedure may be related to these early episodes. Low-level tragus stimulation is a non-invasive form of nerve stimulation applied to the outer ear. It may help regulate the autonomic nervous system and inflammatory responses. This randomized controlled study will evaluate whether low-level tragus stimulation after pulsed field ablation can reduce post-procedural inflammation and early atrial arrhythmia recurrence in patients with atrial fibrillation. Participants who meet the study criteria will be randomly assigned to receive either active low-level tragus stimulation or sham stimulation after the ablation procedure. The study will compare inflammatory markers before and after the procedure, monitor heart rhythm during and after the stimulation period, and assess early atrial arrhythmia recurrence during follow-up. The investigators hypothesize that low-level tragus stimulation may reduce inflammatory responses after pulsed field ablation and may be associated with fewer early atrial arrhythmia episodes compared with sham stimulation.

This study aims to develop and evaluate deep learning-based artificial intelligence models for craniomaxillofacial multi-modal imaging analysis and clinical decision support. Approximately 2,000 participants with craniomaxillofacial imaging data and related clinical information will be included. The imaging data may include two-dimensional facial photographs, cone-beam computed tomography images, and three-dimensional facial surface scans. The study will use artificial intelligence methods to analyze craniofacial images and identify clinically meaningful features related to facial morphology, skeletal or dental classification, anatomical landmarks, regional structures, and craniomaxillofacial abnormalities. The models will be developed for tasks such as image classification, anatomical landmark detection, image segmentation, abnormality recognition, and treatment-related decision support. The purpose of this study is to improve the accuracy, efficiency, and consistency of image-based assessment in dentistry, orthodontics, and oral and maxillofacial clinical practice. The artificial intelligence models developed in this study are intended to provide objective imaging analysis and decision-support information for health care providers. These models are designed to assist clinicians and will not replace professional diagnosis or individualized treatment planning by qualified clinicians. This research may benefit patients and families by supporting earlier and more accurate recognition of craniomaxillofacial conditions, improving communication about diagnosis and treatment options, and promoting more personalized oral health care. All clinical images and related information will be handled according to approved research procedures and privacy protection requirements.

Study on the changes in oral microbiota during orthodontic treatment in patients aged 8-18 years. Orthodontic patients treated at Stomatology Hospital of Xi'an Jiaotong University from March 2025 to March 2027 will be recruited. Prior to orthodontic treatment, routine preoperative examinations will be conducted, informed consent forms will be signed, baseline oral conditions will be recorded, and oral and psychological-related questionnaires will be completed. Patients will be informed of the need for regular oral hygiene check-ups, caries risk assessments will be performed, and plaque, saliva, and intraoral photographs will be collected. During orthodontic treatment, plaque samples will be collected every 3 months, and saliva samples will be collected every 6 months until the treatment is completed to evaluate the changes in oral microbiota throughout the orthodontic process.

The goal of this observational study is to learn the patient journey, disease burden, living situation, quality of life and etc. in patients with Facioscapulohumeral Muscular Dystrophy in all sex/gender and age groups. The main questions it aims to answer are: 1. What's the patient journey of patients with Facioscapulohumeral Muscular Dystrophy? 2. How does Facioscapulohumeral Muscular Dystrophy burden the patients? 3. How's the quality of life of patients with Facioscapulohumeral Muscular Dystrophy? Patients with Facioscapulohumeral Muscular Dystrophy will be asked to: 1. fill a questionnaire. 2. be interviewed and answer questions about their illness experience, economic burden, quality of life and etc. Medical experts on Facioscapulohumeral Muscular Dystrophy will be asked to be interviewed and answer questions about understanding on the disease and the patients.
