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.
Cerebral autoregulation (CA) is the property of the cerebral vascular bed to maintain cerebral perfusion in the presence of changes in blood pressure. In the case of anesthesia, altered cerebral autoregulation, including altered carbon dioxide and hemodilution, can impair physiological changes in the body and lead to poor postoperative prognosis. 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. Our study aimed to investigate the different effects of remimazolam and propofol on dynamic cerebral blood flow autoregulation function during general anesthesia.
How anesthetic drugs induce and maintain the behavioral state of general anesthesia is an important question in medicine and neuroscience. Different anesthetic drugs act on different molecular targets and neural circuit mechanisms, exhibiting drug-specific EEG features. 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 aimed to investigate the differences in the characteristics of EEG oscillations during general anesthesia by comparing propofol and remimazolam.
The study is being conducted to evaluate the safety and tolerability of HRS-4642 in patients with advanced solid tumors harboring KRAS G12D mutation.To estimate the maximum tolerated dose (MTD) and/or a biologically active dose (eg, recommended phase 2 dose [RP2D]) within investigated subject population groups
This phase I clinical trial is to evaluate the safety of Prodencel (an autologous dendritic cell therapeutic tumor vaccine.) in patients with metastatic castration-resistant prostate cancer (mCRPC).
Clinical trials have shown efficacy of PD1/PD-L1 checkpoint inhibitors in multiple solid tumors, including NSCLC. Whole body information with regard to target presence, drug kinetics and dynamics, as well as binding of PD-L1 targeting agents to the immune system cells is lacking.Molecular imaging of PD-L1 could lead to new insights on heterogeneity of PD-L1 expression in metastatic lesions and be of help in the prediction of response to PD1/PD-L1 inhibitors in a noninvasive manner.
Clinical evaluation is crucial in the clinical diagnosis, treatment, and prognosis prediction in patients with traumatic brain injury (TBI). However, the existing evaluation systems are not perfect, because many factors are not taken into account, for example, there is a lack of molecular diagnostic criteria for evaluating patients with TBI. We attempt to collect the patient's clinical data and combine it with neuroimaging, as well as molecular biomarkers generated by single-cell sequencing to assess their neurological status and outcome. The clinical and molecular data collection and analysis will be helpful to evaluate the patient's neurological condition and predict the patient's outcome more accurately.
COVID-19 is currently one of the serious public health challenges worldwide, and there is a great need to develop effective treatments. Paxlovid is a Pfizer-developed oral new drug for the treatment of COVID-19. Paxlovid, which is used to treat adult patients with mild to moderate COVID-19 who have high-risk factors for progression to severe disease, was conditionally approved for marketing in the United States and China in December 2021 and February 2022, respectively. Clinical trials have shown that this drug can significantly reduce the progression from mild to severe disease and the rate of hospitalization and mortality. However, due to the limitations of clinical trials in the subject selection, there is still insufficient knowledge about the efficacy and safety of Paxlovid in a real-world population. Relevant studies on this drug in real-world people, especially in Chinese populations, have not been reported. Therefore, this study was designed to investigate the efficacy and safety of Paxlovid on sufferers of COVID-19 through a retrospective, real-world analysis.
To evaluate the efficacy and safety of donor EBV-specific T lymphocytes (EBV-CTL) infusion in patients with chronic active Epstein-Barr virus infection (CAEBV) and EBV-associated hemophagocytic lymphohistiocytosis (EBV-HLH) after allogeneic hematopoietic stem cell transplantation (allo-HSCT)
Background: Myopia refers to the pathological state in which the external parallel light enters the eye and focuses in front of the retina, resulting in the inability to clearly image on the retina. The number of myopia in China ranks first in the world. According to statistics from the National Health and Health Commission, the myopia rate of children and adolescents nationwide in 2020 will be as high as 52.7%. High myopia often leads to permanent visual impairment and even blindness. Retinopathy complicated by high myopia has become the first irreversible blinding eye disease in Shanghai and other regions. The problem is severe. Therefore, it is necessary to actively seek effective myopia treatment and correction methods to slow down the progression of myopia and the excessive extension of the eye axis and reduce the occurrence of complications. Objective： On the basis of previous research, this study put forward the hypothesis that if behavior management (including outdoor light exposure and close-range eye-use behavior) can be strengthened in children with myopia wearing defocusing frame glasses, it is possible to achieve more effective myopia control effect, thereby not only ensuring safety also effectiveness. A randomized controlled clinical trial is conducted to evaluate the efficacy and safety of defocusing frame glasses with artificial intelligence in controlling myopia progression in children and adolescents. Intervention: Group 1 ( AI defocusing frame glasses group), Group 2 ( Ordinary defocusing frame glasses group). The study period will be 2 years and each participant will be followed up every six month.
The study will investigate whether oxytocin administered either intranasally or orally (lingual) (24 international units, IU) can differentially modulate men's neural and behavioral responses to emotional scenes using an implicit emotional paradigm.
