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.
The investigators will analyze the relationship between the medical history, physiological indicators and the cerebral small vessel disease as well as the structural and functional changes of the brain/head and neck organs in a large sample size of subjects (participants), to identify the influencing factors of the occurrence and development of cerebral small vessel disease as well as the structural and functional changes of the brain/head and neck organs, so as to provide objective clues for early intervention of the disease and improve clinical outcomes.
This study is a multi-center, prospective, randomized controlled clinical trial. The purpose is to compare the difference of indocyanine green fluorescence imaging method and modified inflation-deflation method in identifying intersegmental plane in segmentectomy, and provide high-level evidence for the selection of intersegmental plane identification method in early NSCLC segmental resection.
To evaluate the safety and tolerability of CD19-CAR-DNT cells infusion in subjects with relapsed/refractory B-cell non-Hodgkin's Lymphoma
Weight regain after weight loss is a major problem in the treatment of obesity. Two novel types of intermittent fasting recently have received more attention: the 5:2 diet and time-restricted eating (TRE). TRE requires individuals to eat in a specified number of hours per day (typically 4 to 10 hours) without energy intake restriction. The 5:2 diet involves 5 feast days and 2 fast days per week; participants eat ad libitum without restriction on feast days while 25% of energy needs (approximately 500-800 kcal per day) are consumed on fast day. This randomized controlled trial aimed to evaluate the effect of TRE and the 5:2 diet on weight loss maintenance and cardiometabolic risk factors after a low-calorie diet in obese adults over 12 months compared to usual health care.
Allo-HSCT is the most effective way to cure high-risk MDS patients. At present, the best conditioning regimen for high-risk MDS patients undergoing allo-HSCT remains in discussion. In this prospective study, the safety and efficacy of G-CSF+DAC+BUCY and G-CSF+DAC+BF conditioning regimens in high-risk MDS patients undergoing allo-HSCT are evaluated.
Evaluation of immunogenicity and safety of inactivated COVID-19 vaccine (BBIBP-Cov) coadministered with rabies vaccine.
This phase 2 trial aims to evaluate the efficacy of entecavir prophylacxis for hepatitis B virus (HBV) reactivation that continues until 6 months after completing CD20 monoclonal antibody therapy in patients with CD20-positive B-cell lymphomas and resolved hepatitis B (negative hepatitis B surface antigen, positive hepatitis B core antibody).
The clinical data of all eligible patients who received chemotherapy, radiotherapy, targeted therapy, immunotherapy, interventional therapy and surgery in Henan Tumor Hospital from June 1, 2012 to May 30, 2022 were retrospectively collected.
PD-1 inhibitors have become the standard treatment for advanced hepatocellular cancer, while targeted drugs such as sorafenib and lenvatinib are the first-line standard treatment for hepatocellular cancer. Recent studies have shown that PD-1 inhibitors combined with targeted drugs can improve the efficacy of hepatocellular cancer.To clear the joint treatment in patients with advanced hepatocellular cancer (HCC) efficacy and evaluate its safety, we proposed to carry out the PD - 1 inhibitor (Toripalimab, JS001) joint anti-angiogenesis small molecules targeting drug anlotinib for clinical research,at the same time, based on joint solution of NGS platform testing to predict the curative effect, bring benefit for the long-term survival of patients with hepatocellular cancer (HCC).
Abnormal activity in the central auditory system is the cause of subjective experience of tinnitus. Electrical stimulation can inhibit the abnormal activity of auditory related neurons in patients with tinnitus. In recent years, the application of electrical stimulation in the treatment of tinnitus is a hot research topic, and has made some progress. However, its treatment is still in the discussion stage, and there is no best scheme suitable for clinical practice. At present, scholars have found that cochlear electrode stimulation can inhibit tinnitus, but its mechanism is not clear. It is difficult to locate the origin of tinnitus, and the location of electrode stimulation and stimulation parameters still need to be further optimized. Because the implanted part of the cochlear implant contains magnets, the patients cannot perform functional MRI. However, the prevalence of tinnitus in this group is very high (67.0~100.0%, with an average of 80.0%), so it is of great value and significance to study the effect of tinnitus treatment in such patients. In this study, a new clinical electroencephalogram (EEG) technique was used to make up for the lack of MRI imaging in patients with electrode implantation. EEG analyzes the functional connection of different brain regions through EEG test electrodes, uses the traceability function of EEG software to locate the location of tinnitus, analyzes the process of tinnitus inhibition by electrical stimulation, and explains the mechanism of tinnitus inhibition by electrical stimulation from a new perspective.
