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.
Malignant biliary obstruction usually arise in patients suffering from primary or metastatic hepatobiliary tumors. Approximately 80% of malignant biliary obstruction patients are not eligible for surgical resection, and as such palliative stent insertion is the only treatment option available for most patients. At present, I-125 seeds loaded stent has been developed to improve the stent patency and patients' survival. Hilar malignant biliary obstruction is an important part of malignant biliary obstruction. Hilar cholangiocarcinoma is the most common disease which causes hilar malignant biliary obstruction. Herein, we assessed the clinical and long-term efficacy of I-125 seeds loaded stent insertion for hilar cholangiocarcinoma patients.
Artificial intelligence is deeply integrated with medical diagnosis, and intelligent colonoscopy technology has broad room for development. At present, the assist device of colonoscopy is insufficiently studied. It is the part that needs to be further explored in the development of artificial intelligence colon diagnosis and treatment technology. The study will be conducted at the Digestive Endoscopy Center and it is expected that 380 subjects will participate voluntarily. Subjects met: 1) routine colonoscopy; 2) willing to provide relevant information required by the experiment; 3) signed informed consent for the study. This topic focuses on the colonoscope assist device, through the combination of power assisting device, dynamic analysis, and migration expert skills, to achieve a combination of intelligent power and precise treatment, and establish a prototype of the patient-colonoscopy-assisted assist system-doctor's four-in-one diagnosis and treatment system.
This is a multicenter, randomized, open label, phase III study.
The purpose of this study is to investigate the safety and efficacy of drug-coated balloon angioplasty for the treatment of chronic total occlusions patients with chronic total occlusion (CTO) lesion.
This study mainly evaluated the clinical effect of total arthroscopic repair of the anterior talofibular ligament in the treatment of chronic instability of the lateral ankle. For patients with chronic instability of the lateral ankle, a randomized controlled trial was used to compare the curative effect, operation time, surgical complications, postoperative recurrence rate, postoperative recovery time and patients' satisfaction of the total arthroscopic repair of the anterior talofibular ligament surgery and the modified BrostrÖm surgery.
To confirm the effectiveness and safety of the Dragonfly transcatheter mitral valve repair system for the treatment of symptomatic moderate-to-severe(3+) or severe(4+) degenerative mitral regurgitation (DMR) in high surgical risk subjects.
The primary objective of this study is to evaluate the long-term safety and tolerability of nusinersen administered intrathecally at higher doses to participants with spinal muscular atrophy (SMA) who previously participated in study 232SM203 (NCT04089566). The secondary objective of this study is to evaluate the long-term efficacy of nusinersen administered intrathecally at higher doses to participants with SMA who previously participated in study 232SM203 (NCT04089566).
The objective of this study is to develop and test the psychometric properties of a self-report questionaire, the Glaucoma Visual Functioning Questionnaire-40 (GVFQ-40), which was designed to measure the difficulty of daily activities of glaucoma patients and evaluate the effectiveness of clinical treatment or rehabilitation interventions.
In this study, the investigators proposed a prospective study about the effectiveness of artificial intelligence system for Retrograde cholangiopancreatography. The subjects would be include in an analyses groups. The AI-assisted system helps endoscopic physicians estimate the difficulty of Endoscopic retrograde cholangiopancreatography for choledocholithiasis and make recommendations based on guidelines and difficulty scores. The investigators used the stone removal times, success rate of stone extraction and Operating time to reflect the difficulty of the operation, and evaluated whether the results of the AI system were correct.
Ovarian cancer is the second fatal gynecological cancer. More than 70% of ovarian cancer patients are diagnosed as advanced. Olaparib is the first oral poly adenosine diphosphate-ribose polymerase inhibitor (PAPPi) approved by the U.S. Drug Administration (FDA) in December 2014. It can be used as a maintenance treatment for adult patients with platinum-sensitive recurrent epithelial ovarian cancer, fallopian tube cancer, and primary peritoneal cancer after platinum-containing chemotherapy has achieved complete or partial remission. At present, most studies based on olaparib are randomized controlled trials (RCTs). Because RCTs often have strict inclusion and exclusion criteria and they are implemented in a highly standardized environment. Its internal validity is high, but the research results may not be able to be extrapolated to practice. This study is a prospective real world study. In this study, based on the modified Response Evaluation Criteria in Solid Tumors (RECIST 1.1), we evaluate the use of olaparib in patients with ovarian cancer, fallopian tube cancer, and primary peritoneal cancer in the progression-free survival (PFS), overall survival (OS), and objective control rate (ORR), etc. At the same time, the safety and tolerability of olaparib and the impact on the quality of life of patients are evaluated. Finally, we analyze the results as a supplement to the conclusions of randomized controlled trials to provide better guidance for patients.
