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.
Addition of Anlotinib Hydrochloride to the Stupp Regimen Versus the Stupp Regimen Alone for Newly Diagnosed Glioblastoma.Take PFS as the main evaluation index, the purpose is to evaluate its effectiveness
Meniscus injury is common in sports-active population, and partial or total meniscectomy is standard surgery for meniscal tear. Meniscus plays an important role in load transferring, shock absorbing, knee joint stabilizing and chondral protection. Plenty of studies indicate that meniscus-deficiency increases the risk of OA and cause long-term poor outcomes. Spontaneous human meniscus regeneration is rarely reported and whether regenerated meniscus is chondral-protective and can prevent OA progression remain unknown. During our clinical practice, we have encountered many cases with complete meniscal regeneration under arthroscopy. In this study, we will include all the patients who receiving meniscectomy and ACL reconstruction and knee arthroscopy 2 years after primary surgery. Patients demographic characters will be reviewed. The resected meniscus in the primary surgery and biopsied regenerated meniscus will be analyzed by histological and immunohistochemical method and their ultrastructure will be observed by electron microscope. Patients will be followed at 2-, 5- and 10-year after the primary surgery and the cartilage degeneration and OA progression will be assessed.
Biological samples are important human genetic resources, which can provide great value for medical research, and how to protect and rationally utilize them is of great importance.However, at present, the blood samples after laboratory examination and the damaged tissue cleaned up in the operation will be treated as medical waste and treated according to the standard of medical waste.However, if these samples can be effectively collected and reasonably used, they can provide extremely high value for the study of sports injury-related diseases.Sports injury and joint structure belongs to multiple factors cause abnormal, through the degenerative osteoarthritis, cruciate ligament injury, patellar dislocation, discoid meniscus injury related basic research project establishment and collect the founding the research institute of sports medicine treated patients with sports injury, including degenerative osteoarthritis, intraoperative tissue, blood and saliva samples,To sample from the micro level of susceptibility genes and molecular signaling pathways to anatomical morphology and histopathologic study direction, and so on, can also for multiple transverse comparison research between samples, in order to investigate sports injury, including degenerative osteoarthritis pathogenesis, for sports trauma related disease etiology, diagnosis, treatment to provide new ideas and methods,And the selection of athletes, athletes special training plans, sports mode to provide more targeted suggestions.This study strictly complied with the Regulations of the People's Republic of China on the Management of Human Genetic Resources to establish the Institute of Sports Medicine Sample Bank, which can reduce the waste of human genetic resources in China, promote the development of the discipline, and provide a higher platform for the study of sports injure-related diseases.
The aim of the study is to identify the efficacy and safety of methotrexate (MTX) combined corticosteroid treatment for grade III-IV acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).
To compare the prognosis of patients with hypertensive intracerebral hemorrhage treated by two different surgical methods, and to clarify the therapeutic effect of minimally invasive surgery, so as to find a better surgical method that can reduce surgical trauma and mortality and improve the prognosis of patients
The important role of nutritional management in the treatment of ICU patients has been paid more and more attention. Reasonable nutritional management can improve the nutritional status of patients, reduce the risk of malnutrition, shorten the length of ICU stay, improve the quality of life of patients, and reduce the mortality of patients, thereby improving the prognosis. Many studies have investigated the nutritional status and implementation of ICU patients. It is generally believed that the nutritional status of ICU patients is not good, and the implementation of standardization needs to be improved.The data on the nutritional status and implementation of RICU patients in mainland China is rare. Therefore, the main purpose of this study is to investigate the implementation and compliance of nutritional support treatment for RICU patients in mainland China.
Knee joint is the most common part of sports injury. MRI is a powerful tool to diagnose knee joint injury. However, it takes a long time to read the film, needs a lot, and some hidden injuries have a high rate of missed diagnosis. The emerging deep learning technology can establish automatic recognition model through large samples. A large sample of knee joint MRI was collected retrospectively to train the deep learning model of knee joint MRI, and the sensitivity and specificity of the deep learning model were verified in multi center. Depending on the clinical needs, the deep learning model annotation system is established. A large number of knee MRI were obtained and labeled. According to the knee joint MRI training depth learning model, and iterative optimization, the final version is formed. Multi center validation was carried out. Continuous operation records and corresponding preoperative knee MRI were obtained from multiple hospitals. The sensitivity and specificity of the model were calculated with operation records as the gold standard. At the same time, an expert team composed of senior radiologists and sports medicine doctors was organized to read the films. The sensitivity and specificity of manual reading and AI reading were compared to prove the superiority of AI reading. This study can improve the efficiency of clinical MRI film reading, reduce the workload of doctors, improve the film reading level of grass-roots hospitals, promote the development of the discipline, and has good social benefits and market prospects.
This study aims to evaluate the efficacy and safety of crovalimab in pediatric participants with aHUS.
The next-generation sequencing (NGS) based on liquid biopsy has been an emerging technology to identify tumor-specific genetic aberrations in malignant tumors. The tumor tissue (FFPE) and plasma samples from the newly diagnosed pediatric mature B-NHL patients were collected and sequenced by 475 genes panel before, during and post treatment, to evaluate the significance of the ctDNA in efficacy prediction, predicting recurrence or mechanism of resistance to chemotherapy for pediatric mature B-NHL.
The present study was aimed to investigate the kinematics differences between round-tunnel (ROT) and flat-tunnel (FLT) techniques and compare the influence to the anterior root of lateral meniscus (ARLM ) in anterior cruciate ligament (ACL) reconstruction when using hamstring graft.
