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 explore the effect and prognosis of endovascular interventional therapy in high-risk patients with aortic arch dissection and aneurysm
MAGNET is a multi-center and prospective study to minimize Gadolinium-based Contrast Agent (GBCA) combining novel artificial intelligence (AI) methods with pre-contrast images and/or low-dose images to synthesize virtual contrast-enhanced T1 (vir-T1c) images, based on a large clinical and MRI database and subsequently validated for its clinical value. MRI examinations for patients included T1-weighted images (T1WI) before and after contrast agent administration and at two dose levels: low-dose (10% or 25%) and full-dose (100%), T2-weighted images (T2WI), fluid-attenuated inversion recovery (FLAIR), and diffusion-weighted imaging sequences (DWI) and the computed apparent diffusion coefficient (ADC), all either acquired three dimensional [3D] or two dimensional [2D]). The standard dose of intravenous gadolinium contrast agent was 0.1mmol/kg(body weight) by manual injection or automatic injection with a high-pressure syringe at a flow rate of 4mL/s.The sequence parameters used for the 3DT1WI scans must be consistent, and the standard for intravenous injection of gadolinium contrast agent is 0.1mmol/kg (body weight), administered either manually or automatically with a high-pressure syringe at a rate of 4mL/s. Additionally, arterial spin labeling (ASL), amide-proton transfer chemical exchange saturation transfer (APT-CEST), susceptibility-weighted imaging (SWI), or quantitative susceptibility mapping (QSM) can be acquired at the same time if the conditions permit.
Non-alcoholic fatty liver disease (NAFLD) affects 25% of the global population and causes serious complications, including cirrhosis, hepatocellular carcinoma or mortality. Unfortunately, there are not yet any approved drugs to treatment NAFLD. The only effective means to improve NAFLD is by weight reduction via lifestyle modifications, i.e., diet and physical activity. Most NAFLD patients lack the motivation to initiate and maintain lifestyle modifications. The investigators hypothesize that ambulatory monitoring of liver fat can help NAFLD patients lose more liver fat by motivating them to gain a sense of control over their condition.
The goal of this observational study is to establish and verify the Chinese version of surgical risk assessment system and explore its clinical application. The main questions it aims to answer are: The process of establishing a Chinese version of surgical risk assessment system; What is the accuracy of the system; How can the system be used in clinic; How does this system compare with other systems (such as NSQIP). Participants will comprehensively collect the general information, examination and pathological information of the patients, using machine learning and artificial intelligence methods for data processing. Finally, the Chinese version of the surgical risk assessment system will be established. After the system is established, investigators will evaluate the accuracy of the system and compare it with other related systems.
Investigators intend to combine low-dose hypersensitivity with high-dose immunopotentiation effect, and use super-hyperfractionation pulse radiotherapy, which is expected to achieve the effect of in situ vaccine that can enhance tumor killing, protect normal tissues, reduce immune cell damage and enhance tumor immunogenicity at the same time, and play a stronger immunopotentiation effect in combined immunotherapy. Thereby inducing a stronger abscopal effect of radiotherapy.
This is a single-arm, exploratory study. People with recurrent platinum-resistant ovarian cancer who have not received any previous systemic antitumor therapy for ovarian cancer were selected to evaluate the efficacy and safety of adebrelimab combined with fuzuloparib.
Safety and efficacy of FMT in Pediatric Functional
Hypertension is the most common complication in patients with diabetes nephropathy. Strengthening blood pressure and blood sugar control is the basic treatment for patients with diabetes nephropathy. Angiotensin receptor blocker (ARB) and angiotensin-converting enzyme inhibitor (ACEI) are the first line drugs recommended in domestic and international guidelines for diabetes patients to control hypertension. As a new ARB drug, azilsartan has been found to have better antihypertensive effect than other ARB drugs. However, due to the limited sample size and study time, azilsartan has no significant advantage over other ARB drugs in terms of renal protection effect, and has not been systematically studied in diabetes nephropathy population. This study is intended to evaluate the effect of azilsartan on proteinuria and blood pressure improvement in patients with diabetes nephropathy and hypertension through clinical randomized controlled study, so as to accumulate evidence-based evidence of azilsartan in the comprehensive management of heart and kidney protection in this group of people, and promote the development of comprehensive treatment for patients with metabolic disease and renal injury combined with hypertension. This study will compare the advantages and disadvantages of azilsartan and classical ARB drug losartan potassium in terms of proteinuria, blood pressure control and renal function protection in patients with diabetes nephropathy and hypertension; We propose that the main indicator is the change of urinary albumin/creatinine ratio relative to the baseline, and the secondary indicator is the change of 24-hour urinary protein relative to the baseline; Change of blood pressure relative to baseline; Renal function, electrolyte and blood glucose.
The aim of this study is to test if stellate ganglion block can decrease the incidence of atrial fibrillation after video-assisted thoracoscopic surgery and the way it works.
To evaluate the efficacy and safety of rezvilutamide in combination with androgen deprivation therapy(ADT) and standard salvage radiation therapy(SRT) or rezvilutamide in combination with ADT in prostate cancer patients with biochemical recurrence of prostate-specific antigen(PSA) persistence after radical prostatectomy(RP).
