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.
Dermatomyositis is a heterogeneous disease characterized by involvement of the proximal muscles of the extremities. Some patients have treatment failure or intolerance to the above treatment regimens, which is called refractory dermatomyositis. Abatacept has been approved by the FDA for the treatment of three types of rheumatoid immune diseases, and the international consensus of experts recommends abacepil as a second-line regimen for the treatment of refractory dermatomyositis based on the evidence of case reports.
This project is planned to be based on the medical insurance database collected by the China Health Insurance Research Association (CHIRA). As a national academic research institution, CHIRA collects medical insurance patient data, covering more than 20 provinces across the country. The data of more than 60 municipalities, provincial capitals, and prefecture-level cities are unique and authoritative in my country. Based on the CHIRA database, big data analysis for Chinese sports medicine patients, starting from the names of medical institutions, admission/discharge diagnosis and classification of medical items, etc., to investigate the development trend of arthroscopic surgery in China and understand my country's arthroscopic diseases The distribution characteristics and changing trends of the quantity.
This Phase II study is to determine the efficacy and safety of MR-Linac Guided Adaptive fractionated stereotactic radiotherapy (FSRT) in patients with brain metastases in non-small cell lung cancer.
Hepatic artery infusion chemotherapy (HAIC) and anti-programmed cell death protein-1ligand (PD-L1) immunotherapy have shown promising outcomes in patients with advanced hepatocellular carcinoma (HCC), respectively. However, the combination of the two treatments has not been reported. In this study, we will evaluate the the overall survival (OS)、efficacy and safety in patients with advanced hepatocellular carcinoma (Ad-HCC) with portal vein embolism who are undergoing hepatic arterial infusion (HAI) of oxaliplatin, fluorouracil/leucovorin (FOLFOX) treatment combined with anti-PD-L1 immunotherapy (Durvalumab) by designing an open, single-arm phase II clinical study.
Recently, natural D-glucose was suggested as a potential biodegradable contrast agent. The feasibility of using D-glucose for dynamic perfusion imaging was explored to detect malignant brain tumors based on blood brain barrier breakdown. Our study try to evaluate the feasibility of dynamic glucose enhanced(DGE) magnetic resonance imaging（MRI）in brain tumor, which based on D-glucose weighted chemical exchange saturation transfer (gluceoCEST).
The primary object of this study is to determine tumor major pathological response (MPR) rate and pathologic complete response (pCR) rate in stage IB-IIIA non-small cell lung cancer who subjected to neoadjuvant immune checkpoint inhibitor combined with chemotherapy and molecular biomarkers related to the clinical response.
Different types of statins show different influences on glycometabolism. There are no systemic analyses of the effects that statins exert on the metabolism of glucoses so far in China. This research aims to compare impacts on the glycometabolism of pitavastatin in AMI patients with atorvastatin and to accumulate data for guiding the utilization of statins.
We intend to compare the efficacy and safety of immunotherapy plus stereotactic body radiotherapy at oligometastatic lesions and immunotherapy alone among patients with oligometastatic nasopharyngeal carcinoma whose primary lesion has been well controlled after radical local-regional treatment through this multicenter randomized phase 3 trial.
Main objective: To evaluate the efficacy, safety and clinical dose exploration of Qishen Yiqi dripping pills in the treatment of chronic heart failure with preserved ejection fraction. Exploratory research objective: To explore the changes of endogenous substances in vivo before and after drug administration, to interpret the mechanism of drug action through metabolomics and systems biology methods, and to find potential clinical biomarkers for exploratory subgroup analysis of clinical trials.
The injury and remodeling mechanism about upper extremity motor network after stroke is not clear. There are few studies on the motor network covering cortex, white matter and blood perfusion at the time. Some studies have shown that metal imagery activates the cortex through active mental simulation. Our previous study has shown that passive application of transcranial direct current stimulation causes subthreshold polarization and promotes the effective integration of residual brain high-level network. This study proposes a hypothesis: transcranial Direct Current Stimulation + Motor Imagery combines active and passive neuromodulation techniques to produce dual channel effect, which can synergistically excite motor cortex, remodel the motor network and optimize cerebral perfusion. The research contents include clarify the effect of transcranial Direct Current Stimulation + Motor Imagery neuromodulation therapy through comprehensive randomized controlled trial study; present the process of brain injury and secondary neural plasticity through the motor network construction, functional connectivity strength and cerebral perfusion with Blood Oxygen Level Dependent, Diffusion Tensor Imaging and Arterial Spin Labeling multimodal magnetic resonance technology; calculate the correlation between motor score and brain functional network, extract the key nodes that can promote the motor network remodeling. The research results are expected to provide preliminary theoretical foundations for further research on the injury and remodeling mechanism about upper extremity motor network after stroke.
