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 purpose of this study was to evaluate the effect of Helicobacter pylori infection on the quality of gastric mucosa preparation.
In the era of comprehensive therapy, many studies have investigated the value of induction chemotherapy (IC) in the treatment of nasopharyngeal carcinoma (NPC). Concurrent cisplatin and radiotherapy is the foundation of concurrent chemoradiotherapy strategies, and the addition of cisplatin-based induction chemotherapy to concurrent chemoradiotherapy (CCRT) is considered to prolong survival by reducing distant metastasis in patients with high-risk disease. However, the severity of acute toxicities was significantly increased, which can compromise quality of life and lead to interruptions in CCRT. Fortunately, Locoregional control has substantially improved as the intensity-modulated radiation therapy (IMRT) technique has been widely used in the last decades, IMRT improved the treatment outcomes of patients with NPC, especially the local control rate. Currently, in the era of IMRT, whether patients with NPC benefit from IC plus radiotherapy alone and reduce toxicities compared with IC combined with CCRT. Therefore, the investigators propose this randomized phase III prospective study to assess the efficacy and contribution of IC plus radiotherapy alone in locoregionally advanced NPC during IMRT era.
The purpose of this study is to evaluate the clinical efficacy, safety and immunological changes of secukinumab(sec) compared to adalimumab(ada) in patients with active ankylosing spondylitis(AS), who previously have an inadequate response to non-steroidal anti-inflammatory drugs (NSAIDs) or bioagents.
As a novel ultra-short-acting benzodiazepines drugs, Remimazolam has been accepted for induction and maintenance of clinical anesthesia. Compared to the traditional benzodiazepines drugs, Remimazolam combines the safety of midazolam with the effectiveness of propofol, and also has the advantages of acting quickly, short half-life, no injection pain, slight respiratory depression, independent of liver and kidney metabolism, long-term infusion without accumulation, and has a specific antagonist: flumazenil. This study aims to investigate whether Remimazolam reduces the incidence of emergence agitation in children after ophthalmic surgery, compared to sevoflurane (RCT).
This is a bridging study to visually and quantitatively assess PET images obtained after single application of 300 MBq [18F]florbetaben and PET scanning of patients with Alzheimer disease.
Peripheral T-cell lymphoma (PTCL) is a highly heterogeneous group of aggressive non-Hodgkin lymphoma (NHL) originating from mature thymus T cells.Mitoxantrone Hydrochloride Liposome Injection can accelerate the entry of mitoxantrone into cells, reduce the efflux of mitoxantrone, ensure the concentration of intracellular drugs, reverse the drug resistance mechanism, and enhance anti-tumor activity.We will explore the dose-limiting toxicity (DLT) of Mitoxantrone Hydrochloride Liposome Injection combined with Chidamide in the treatment of relapsed or refractory peripheral T-cell lymphoma, estimate the maximum tolerated dose (MTD) of the combination, and determine the phase II recommended dose RP2D.In the phase II study, we will evaluate the safety and efficacy of the combination regimen.
This study is a single-blinded, randomized, parallel controlled trial.The purpose of this experiment is to confirm how "Yijinjing" treatment affects hand function, handgrip strength, pain, morning stiffness, and mood disorder in RA patients compared to routine care.
α-Synucleinopathy is a cluster of neurodegenerative disease with motor and non-motor symptom. The data to be collected is intended to help healthcare providers make important medical decisions concerning α-synucleinopathy, through an enhanced understanding of the natural history, progression and multi-omics datasets of α-synucleinopathy.
Acute kidney injury (AKI) is a series of clinical syndromes in which serum creatinine (Scr) concentrations increase over a short period of time, or urine output decreases. It has become an increasing global concern.Drug-induced acute kidney injury (D-AKI) refers to kidney injury caused by drugs or their metabolites within 7 days after the use of one or more drugs. The kidneys are rich in blood flow and have the function of acidifying the urine, making them an easy target for drug toxicity. Besides, there are enzymes in the kidney that metabolize some drugs, and if these drugs are metabolized abnormally in the kidney, substances toxic to the kidney may be produced.It was found that about 20% of AKI in hospitalized patients was caused by medications.Diuretics are one of the well-known nephrotoxic drugs, since they can directly or indirectly cause a significant decrease in renal blood perfusion and glomerular filtration rate through the mechanism of affecting tubulobulb feedback, which leads to kidney ischemia and hypoxia.However, there are few real-world studies on the incidence of AKI in hospitalized patients received diuretics. In this study, we aimed to explore the incidence and risk factors analysis of AKI in hospitalized patients received diuretics and develop the machine learning model for diuretics related AKI based on electronic medical record data. With the individual characteristics of patients, the risk of AKI can be evaluated before receiving diuretics, which may provide useful information for clinical decision making to better prevent D-AKI.
This study is a randomized and controlled Phase IV clinical trial.The purpose of this study is to evaluate the immunogenicity and safety of combined immunization with live attenuated varicella vaccine and inactivated hepatitis A vaccine in children aged 12-15 months.
