There are about 36818 clinical studies being (or have been) conducted in China. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Data intelligence platform was widely used to facilitate the process of clinical research. However, a platform that integrates natural language processing (NLP) and machine learning (ML) algorithms has not been reported in perioperative medical management.
PSMA is highly expressed on the cell surface of the microvasculature of several solid tumors, including glioma. This makes it a potentially imaging target for the detection and grading of gliomas. This pilot study was designed to evaluate the diagnostic performance of 68Ga-P16-093, a novel radiopharmaceutical targeting PSMA, which was compared with MRI in the same group of glioma patients.
This is a single, retrospective, observational study to investigate the risk factors for achieving textbook outcome after laparoscopic duodenum-preserving total pancreatic head resection.
This study is a clinical validation of our developed a computer-aided optical dignosis of advanced adenoma using non-magnified NBI image. This study is a randomized clinical trial comparing endoscopists' optical recognition of advanced adenoma for sending to histological examination with our computer-aided system. The hypothesis of the study is that the developed computer-aided system increases the percent of sending actual advanced adenoma Intelligence Assisted Optical Diagnosis of Advanced Adenomas
This trial is a clinical study to evaluate the safety of sequential boosters of novel coronavirus mRNA vaccine in adults aged 18 years and older who have completed three doses of novel inactivated coronavirus vaccination. According to the results of the previous phase I clinical trial, the incidence of adverse reactions in the 0.3 ml dose group was lower than that in the 0.5 ml dose group, and the degree of adverse reactions was weaker. The dose of 0.3ml was chosen for the current study, and a 1-dose immunization program was completed for safety observation.
Postherpetic neuralgia (PHN) is the most frequent complication of herpes zoster(HZ) and is defined as pain persisting for >1month after the healing of herpetic skin lesion or pain persisting for > 3 months following the onset of HZ. PHN manifests as spontaneous throbbing, stabbing, or burning, usually accompanied by various abnormal sensory symptoms , which affect 5-20% of patients with HZ. Due to the lack of accurate and objective auxiliary examination tools, it is difficult for diagnosis and treatment of PHN. As a non-invasive examination method, infrared thermal imaging (IRT) can play a role in the diagnosis and treatment of neuropathic pain by objectively reflecting the changes and distribution characteristics of human body surface temperature. However, there are few studies on the relationship between clinical phenotype and thermal infrared image temperature changes in PHN patients, and the relationship between the thermal pattern of skin temperature and the duration of disease and treatment progress in PHN patients has not been fully elucidated. This study was conducted to investigate the relationship of thermal imaging data with the duration of the disease, clinical phenotype, treatment effect, in order to explore the role of infrared thermal imaging in the diagnosis and treatment of PHN. Methods：all PHN patients will included. At each visit, a pain NRS score was performed, and clinical phenotypes were tested and labeled, including: allodynia, numbness, itching, heat sensation, cold sensation, and the most painful area(MPA). Infrared thermal imaging was performed, the Average Relative Temperature (ART) within the affected area and the contralateral area was compared. The relationship between the temperature change and duration of the disease, clinical phenotype, treatment effect was assessed.
This randomized Phase 3 open-label study will compare the efficacy of the T-cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif (ITIM) domain (TIGIT) monoclonal antibody domvanalimab, the anti programmed cell death protein 1 (PD-1) monoclonal antibody zimberelimab, and multiagent chemotherapy versus the anti PD-1 monoclonal antibody nivolumab and multiagent chemotherapy in the first-line treatment of participants with locally advanced unresectable or metastatic gastric, gastroesophageal junction (GEJ), and esophageal adenocarcinoma.
This study is being conducted to evaluate the safety and effectiveness of GC301 adeno-associated virus vector expressing codon-optimized human acid alpha-glucosidase (GAA) as potential gene therapy for Pompe disease. Patients diagnosed with infantile-onset Pompe disease who are younger than 6 months old will be studied.
This study is designed as a phase-II proof of clinical trial to investigate if a treatment strategy where stereotactic body radiation therapy (SBRT) is given with pembrolizumab is sufficiently active to warrant further investigation in randomized phase II or III studies. Metastatic renal cell cancer (mRCC) patients with PD-1 expressing immune cells are more likely to have larger more aggressive tumours and reduced survival. Pembrolizumab is designed to directly block the interaction between PD-1 and its ligands, PD-L1 and PD-L2. SBRT will be given to the 1-5 most clinically significant lesions after the 1nd course of pembrolizumab treatment in an effort to improve the activity of pembrolizumab.
The purpose of this study is to find out appropriate dose range of dexmedetomidine to provide the elderly patients satisfactory sedation and analgesia with stable hemodynamics during perioperative period of hip replacement under general anesthesia.
