Clinical trials

This study is a prospective,multi-center and observational clinical study.Investigators would like to innovatively construct a "trinity" database of colorectal tubular adenomas based on white light - magnifying chromo - pathological images.It simulates the decision - making logic of doctors, and based on the multimodal endoscopic LAFEQ method previously proposed, develop a multimodal deep - learning diagnostic model for colon adenomas and an interpretable risk prediction model for intestinal adenomas. While achieving high - precision auxiliary treatment decisions, clearly present the decision - making basis, and break through the limitation of poor interpretability of previous medical imaging AI models.

Colorectal cancer has the third highest incidence and second highest mortality rate of all malignant tumors worldwide. Distinct from most other cancers, colorectal cancer can be prevented; colonoscopy-based identification and removal of adenomatous polyps is the most effective preventive measure. Early intestinal adenomas rarely cause specific symptoms, and many patients are diagnosed at advanced stages once symptoms emerge, leading to unsatisfactory treatment and prognosis. Colonoscopy, the main diagnostic tool for intestinal adenoma, is invasive, resulting in limited patient compliance, while grassroots hospitals face shortages of medical resources. There is an urgent demand for a convenient, affordable and well-tolerated early diagnostic method for intestinal adenoma. Artificial intelligence techniques can efficiently analyze routine clinical laboratory data. This study aims to establish an AI-based predictive model combining clinical information and laboratory test results to realize early identification of intestinal adenoma and optimize patient prognosis.

The goal of this multicenter, double-blind, randomized controlled trial is to evaluate the efficacy and safety of low-intensity focused ultrasound (LIFU) stellate ganglion modulation for preventing ventricular arrhythmias after ST-segment elevation myocardial infarction (STEMI) in patients undergoing percutaneous coronary intervention (PCI). The main questions it aims to answer are: 1. Does LIFU reduce the frequency and duration of ventricular arrhythmias within 72 hours post-PCI compared to sham ultrasound? 2. Does LIFU improve electrophysiological stability, myocardial injury markers, cardiac function and heart rate variability, and reduce inflammatory markers and sympathetic neurotransmitters? 3. What is the safety profile of LIFU in this population? 100 eligible patients will be randomized 1:1 to receive either active LIFU (2.0W, 1MHz, 50% duty cycle, 30min per session: 1 intra-PCI session + 7 daily post-PCI sessions) plus standard care, or identical sham ultrasound plus standard care. A comprehensive double-blind design (subjects, operators, assessors, statisticians) will be implemented. The study will run from May 2026 to April 2027 at 7 centers in China, led by Renmin Hospital of Wuhan University. Participants will: 1. Complete pre-PCI screening and baseline assessments (informed consent, demographic/medical history, physical examination, electrocardiogram, echocardiogram, blood sample collection) within 12 hours of symptom onset 2. Receive 1 assigned ultrasound intervention during PCI, followed by 1 daily intervention for 7 consecutive days postoperatively 3. Undergo 72h continuous ECG monitoring post-PCI, blood sampling at baseline and postoperative days 1, 3, 7, and echocardiography assessment at postoperative day 7 4. Have all adverse events and arrhythmias recorded throughout the study 5. May withdraw voluntarily at any time without affecting routine medical care

This clinical study was a multi-center, open-label, randomized controlled clinical trial. A total of 472 patients with early-stage cardiogenic shock were recruited and randomly divided into the experimental group and the control group, with 236 cases in each group. The HeartMed-HF digital out-of-hospital management was used to manage the patients in the experimental group, while the patients in the control group were managed according to the discharge guidance. The primary endpoints were 1-year all-cause mortality and unplanned readmission after randomization (excluding emergency department visits). Secondary endpoints (at 3 months, 6 months, and 12 months post-randomization) were: all-cause mortality, rehospitalization for HF, recurrent MI, ischemia-driven repeat revascularization, stroke, BARC 3-5 grade major bleeding, unplanned formal rehospitalization, types of GDMT medications or GDMT target dose achievement rate.

This is a multicenter, randomized, double-blind, controlled trial to evaluate the efficacy and safety of an enhanced strategy of allergen-specific immunotherapy (ITIT) in the treatment of allergic rhinitis. By recording the changes in CSMS from baseline to post-treatment in the subjects and the incidence of adverse reactions after treatment, the differences in efficacy and safety between the patients who received the basic three doses and those who received booster injections were compared. Furthermore, the impact of different booster strategies on long-term efficacy was compared to optimize the injection strategy. At the same time, the influence of different administration procedures on the immune response was evaluated.

In recent years, computer-aided diagnosis system based on artificial intelligence (AI) has been used in colorectal polyp detection. In recent years, computer-aided diagnosis system based on artificial intelligence (AI) has been used in colorectal polyp detection. However, whether AI-assisted can improve the adenoma-detection rate (ADR) is inconclusive. This study aims to evaluate the real-world performance of an AI system that combines polyp detection with colonoscopy quality control. This study aims to explore the clinical application value of AI-based polyp detection and quality control function by comparing the data of polyp detection rate and adenoma detection rate in multiple centers with and without AI-assisted colonoscopy in a multicenter, prospective real world study.

This study is a multicentre, randomised, parallel-controlled, open-label, 3 phase clinical trial. The subjects were untreated, unresectable locally advanced, recurrent or metastatic esophageal squamous cell carcinoma with low PD-L1 expression. Patients were randomly assigned to receive chemoradiation or chemotherapy in combination with Tislelizumab at a ratio of 1: 1. The primary endpoint was progression-free survival (PFS) in the intention-to-treat population. We hypothesized that in advanced esophageal squamous cell carcinoma patients with low PD-L1 expression, chemoradiation versus chemotherapy in combination with Tislelizumab will significantly improve PFS.
