The benefit of intravenous tenecteplase for acute ischemic stroke with unknown time of onset, e.g. wake-up stroke, remains uncertain. This randomized study aims to assess the efficacy and safety of intravenous tenecteplase following non-contrast CT screening for acute ischemic stroke with unknown time of onset.

The goal of this clinical trial is to evaluate and compare the efficacy and safety of three commonly used antiparasitic drugs-albendazole, tribendimidine, and praziquantel-for the treatment of clonorchiasis, a liver fluke infection acquired by consuming raw or undercooked freshwater fish. This study aims to answer the following primary questions: How effective is each drug in achieving parasitological cure, as measured by clearance of Clonorchis sinensis eggs in stool? What types and frequencies of adverse events are associated with each treatment? Participants in this randomized, open-label trial will: Be randomly assigned to receive one of the three study drugs according to a predefined dosing regimen. Provide stool samples before treatment and at follow-up to assess for Clonorchis sinensis eggs. Undergo a second round of the same treatment regimen and repeated stool examination if eggs are still detected after the first course. Attend follow-up visits, which include symptom assessment and blood tests (hematology and liver function). Report any side effects, discomfort, or adverse reactions experienced during or after treatment. The findings from this study will help inform optimal therapeutic strategies for clonorchiasis in outpatient clinical settings.

Optic neuritis is an important cause of acute or subacute visual loss. In clinical practice, optic neuritis must often be distinguished from other optic neuropathies, retinal diseases, anterior-segment or ocular media disorders, non-organic visual loss, and other mimics. The 2022 International Criteria for Optic Neuritis were developed to standardize the diagnosis of optic neuritis, but their performance in Chinese clinical settings, where aquaporin-4 immunoglobulin G positive and myelin oligodendrocyte glycoprotein immunoglobulin G positive optic neuritis are relatively common, remains uncertain. This multicenter prospective observational study is enrolling patients with acute or subacute visual loss or visual dysfunction in whom optic neuritis is included in the differential diagnosis. The study is designed to evaluate the diagnostic performance of the 2022 International Criteria for Optic Neuritis alone and with an antibody-stratified adjunct. The index classifications will be compared with an expert-adjudicated reference-standard diagnosis. No experimental treatment is assigned by the study. All diagnostic tests and treatments are determined by the treating clinicians according to routine clinical care. Study data are collected using a structured protocol-defined case report form.

This multicenter clinical study is evaluating CascadeDiagnose Prostate MRI, an artificial-intelligence software tool that analyzes standard prostate MRI scans-T2-weighted, diffusion-weighted, and ADC images-to help radiologists detect suspicious prostate lesions, estimate cancer risk, and distinguish prostate cancer from benign conditions. The study will take place at six hospitals in Guangxi and plans to enroll at least 2,000 eligible men aged 18 or older who have had prostate MRI and have confirmed pathology results. It includes a retrospective phase using existing records and a prospective phase in which participants provide written informed consent. The main goals are to measure the system's diagnostic accuracy (AUC, sensitivity, and specificity), compare it with readings by radiologists, assess safety and rates of rejected or indeterminate results, and see whether it improves reading efficiency or helps reduce unnecessary biopsies. To protect patient privacy, raw MRI, medical-record, and pathology data remain inside each hospital; only de-identified, encrypted intermediate results are shared through a secure distributed network. The study requires ethics approval and trial registration before enrollment, and its results may help determine whether this AI tool is safe and effective for clinical use.

This is a multicenter, retrospective and prospective diagnostic clinical trial evaluating the effectiveness and safety of CascadeDiagnose Renal Tumor CT, an AI-assisted detection system for renal tumors based on contrast-enhanced multiphase CT imaging. The system employs a cascaded deep learning architecture to perform fully automated analysis of multiphase CT images, covering image quality review, lesion detection and segmentation, benign-malignant differentiation, and risk stratification, with traceable evidence chains and interpretable outputs. The study is conducted across six tertiary hospitals in Guangxi, China, utilizing a distributed "data stays on-site, computation moves across centers" federated learning network, which ensures that original patient data remain within each hospital while encrypted intermediate features are shared for cross-center collaborative analysis. A total of at least 3000 patients with renal tumors will be enrolled (approximately 2600 in the retrospective phase and 400 in the prospective phase). The primary effectiveness outcomes include area under the receiver operating characteristic curve (AUC), sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). The primary safety outcomes include false negative rate, false positive rate, and adverse events. The study also incorporates a multi-reader, multi-case (MRMC) design to compare the diagnostic performance of the AI system with radiologists of varying seniority, and to evaluate the system's utility in assisting junior radiologists. The findings of this study are expected to provide high-quality clinical evidence for the regulatory approval of this AI-assisted diagnostic system as a Class III medical device.

The benefit of intravenous tenecteplase in very old patients with acute ischemic stroke (AIS) remain uncertain. This real-world study aims to evaluate the effectiveness and safety of intravenous tenecteplase in AIS patients aged 80 years or older within 4.5 hours of symptom onset.

This multicenter, randomized controlled trial is designed to determine whether omitting prophylactic extraction of impacted teeth before radiotherapy leads to an unacceptably higher risk of jaw osteoradionecrosis (JORN) compared with conventional prophylactic extraction in patients with non-metastatic nasopharyngeal carcinoma (NPC). JORN is a condition in which jawbone tissue is damaged and fails to heal properly after radiotherapy. A total of 536 eligible participants with at least one impacted tooth will be randomly assigned to either omit prophylactic extraction of impacted teeth before radiotherapy or undergo conventional prophylactic extraction before radiotherapy. All participants will receive standard curative-intent intensity-modulated radiotherapy (IMRT), with chemotherapy administered when indicated according to the study protocol. Participants will be followed for up to 5 years. The primary outcome is the incidence of JORN within 2 years after completion of radiotherapy. Secondary outcomes include longer-term incidence of JORN, overall survival, locoregional relapse-free survival, distant metastasis-free survival, quality of life, and treatment-related toxicities.

This study aims to evaluate the real-world effectiveness and safety of third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs)-such as osimertinib, aumolertinib, and furmonertinib-as adjuvant therapy for patients with early-stage non-small cell lung cancer (NSCLC) in China. Approximately 500 eligible patients are planned to be enrolled. All participants must have been diagnosed with Stage IA NSCLC (according to the 8th edition of the AJCC staging system) following surgical resection, harboring EGFR-sensitive mutations, and presenting with high-risk recurrence factors (e.g., poor differentiation, lymphovascular invasion, and spread through air spaces). This is a non-interventional, real-world study that does not alter physicians' original prescribing habits or clinical management strategies. Patients will receive standard treatment with third-generation EGFR-TKIs according to routine clinical practice (typically for a duration of three years). The research team will periodically collect follow-up data, with a primary focus on postoperative disease-free survival (DFS) and drug safety profiles. Through this investigation, we seek to determine whether this specific population of high-risk early-stage patients can derive clinical benefit from postoperative targeted therapy. The findings are expected to provide evidence to support the development of future clinical guidelines.

A multicenter, prospective, randomized controlled clinical trial. The target population consists of patients undergoing IVF/ICSI artificial reproduction who plan to undergo ovarian stimulation and embryo retrieval (DOR) within 4 months. A stratified block randomization method was employed to assign participants in a 1:1 ratio to the intervention group and control group. The study aims to investigate whether multiple-point ovarian cortex puncture during the initial oocyte retrieval procedure improves ovarian reserve and ovarian stimulation outcomes in DOR patients compared to conventional oocyte retrieval techniques.

This study evaluates our team's urology-specific AI (UroMed AI Doctor) for its safety, professionalism, knowledge and Q\&A ability, and tests its effectiveness against traditional manual urology care, to confirm if it can be a safe auxiliary tool and improve patients' preoperative experience. Before the study, we will test the AI with urology questions, compare it to international AI models (DeepSeek, ChatGPT, Google Gemini), and have two senior chief physicians evaluate it. In the clinical trial, patients at The First Affiliated Hospital of Guangxi Medical University will be randomly split into two groups: AI-assisted care or traditional care by a specialist. Two senior specialists will evaluate both groups blindly; each group will get preoperative education (AI or physician), with anxiety and satisfaction surveyed. Subsequently, a multi-center validation will be conducted with 11 domestic and international hospitals.

Radiation-induced oral mucositis (RIOM) is an inevitable acute complication in radiotherapy for head and neck malignancies, characterized by a complex pathogenesis involving multiple biological processes. According to the latest data from the International Agency for Research on Cancer (IARC), approximately 650,000 new cases of head and neck cancers are diagnosed globally each year, with about 70% of patients undergoing radiotherapy. RIOM develops through a multistep pathophysiological cascade, including initiation of mucosal injury, signaling amplification, inflammatory response, ulceration, and eventual healing. Ionizing radiation induces DNA damage in oral mucosal epithelial cells, triggering increased apoptosis. This cellular injury promotes the activation and release of pro-inflammatory mediators such as tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6), compromising the integrity of the mucosal barrier and ultimately leading to ulcer formation. Current clinical management of RIOM remains largely supportive, relying on oral hygiene, nutritional supplementation, and pain control, with no effective prophylactic agents available. Despite extensive research into potential interventions internationally, no drugs specifically approved by the FDA or NMPA for the prevention of RIOM have reached the market. This significant unmet clinical need calls for urgent scientific and therapeutic advancement. This study aims to evaluate the therapeutic efficacy and safety profile of aerosolized exosomes derived from mesenchymal stem cells in the prevention and treatment of radiation-induced oral mucositis in patients receiving radiotherapy for head and neck cancers. The ultimate objective is to establish a novel and effective therapeutic strategy for clinical application.
