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.
To evaluate the safety of autologous CAR-T cell injection in the treatment of recurrent and refractory hematopoietic and lymphoid tissue tumors
To investigate the effect of different degrees of fat infiltration on rocuronium use in lumbar surgery was monitored by trapezius muscle relaxation.
The electrocardiogram is one of the most basic tests for cardiovascular disease. T wave alternans (TWA), which reflects abnormal ventricular repolarization, can easily trigger ventricular tachycardia (VT) and ventricular fibrillation (VF), which are important warning clues for sudden cardiac death (SCD). The late sodium current (INaL) is an important component of the frequency-dependent regulation of cardiac repolarization, and various causes of delayed repolarization can increase INaL. Our study on long QT syndrome (LQTS) found that INaL abnormalities can lead to abnormal myocardial repolarization, producing a giant TWA that triggers VT and VF. VT and VF, and INaL inhibition by the INaL blocker mexilate can terminate this process. This suggests that pharmacological blockade of INaL may be a potential target for the prevention of SCD by ameliorating the different causes of giant TWA and its triggering ventricular arrhythmic events. In this study, we propose to randomize patients with VT/VF triggered by giant TWA to conventional treatment and conventional treatment adds mexiletine treatment to compare the effects of the two treatment regimens on giant TWA and its triggered nonsustained VT, sustained VT, and VF; at the same time, we will compare the effects of mexiletine on giant TWA and its triggered ventricular arrhythmias of various etiologies by intra-group control before and after treatment. The safety and efficacy of the treatment of TWA and its triggered ventricular arrhythmias are compared.
To investigate the evolution of imaging appearances and cognitive function of Moyamoya disease (MMD) and to establish a prognosis evaluation system based on imaging biomarkers in MMD. The study may be helpful to optimize and improve the diagnosis and pretreatment assessment of MMD, and provide an important theoretical supplement to the existing guidelines for the management of MMD.
Study Description The goal of this observational study is to detect intestinal flora and the metabolic products in premature infants diagnosed as necrotizing enterocolitis. The main questions it aims to answer are: - 1. Whether there is intestinal flora in the stool of premature infants. - 2. Are there dysregulated intestinal flora and their metabolic products in premature infants diagnosed as necrotizing enterocolitis. - 3. The detailed role and underlying mechanism of the intestinal dysbacteriosis and the metabolic products in premature infants diagnosed as necrotizing enterocolitis. Participants, premature infants diagnosed as necrotizing enterocolitis (NEC group), will be asked to collect stool (usually 2 times) for intestinal flora analysis. If there is a comparison group: Researchers will compare premature infants without necrotizing enterocolitis (control group) to see if their intestinal flora and the metabolic products also changed as their NEC counterparts.
Patients with resectable remnant gastric cancer were selected as study subjects to investigate the safety, efficacy, and feasibility of ICG near-infrared imaging tracing in guiding laparoscopic lymph node dissection for remnant gastric cancer by comparing injection ICG group and non-injection ICG group.
The aim of this study was to determine the differences in hemodynamics between different positions in patients undergoing ultra-early reperfusion therapy.
To evaluate the efficacy and safety of Jing Fang Wu Mei Wan Jiawei Fang in the treatment of idiopathic blepharospasm using a clinical randomized controlled trial method.
The primary objective of the study is to describe the natural history and utilization of disease modifying therapy (DMT) among adult Chinese participants with SMA linked to chromosome 5q (5q-SMA).
The purpose of this study is to verify the safety and efficacy of the cardiac pulse ablation system in paroxysmal atrial fibrillation to provide the basis for product registration and clinical application. The trial will be conducted at a clinical center with appropriate clinical cases, and paroxysmal atrial fibrillation ablation procedures will be performed by an authorized investigator using the trial product. The effectiveness and safety of the cardiac pulse ablation system in the treatment of paroxysmal atrial fibrillation will be verified by collecting the treatment success rate, immediate ablation success rate, procedure time and device use evaluation within 12 months after the procedure.
