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 is to assess the effectiveness of acupuncture for treating catheter-related-bladder discomfort in adults after bladder outlet obstruction surgery.
This multicenter prospective cohort study aims to compare the difference in the effects of medical treatment within 1 year between the two groups of ICAS patients divided hemodynamically by Magnetic Resonance Fractional Flow Reserve. PC MRA will be applied for FFR measurement. The primary outcome is the composite of ischemic stroke or death related to the qualifying artery territory for 1 year.
The trial is a multicentre, prospective, open-label, blinded endpoint (PROBE), phase 3, randomized controlled design. Patients with acute ischemic stroke due to basilar artery occlusion presenting within 24 hours will be randomized 1:1 to intravenous tenecteplase (0.25mg/kg, maximum 25mg) ± thrombectomy or 'best practice'which may be alteplase (0.9mg/kg) within 4.5 hours from stroke onset or standard care (no lysis) ± thrombectomy at treating clinician's discretion.
Acute non-traumatic chest pain is one of the common causes of presentation in emergency patients, but the causes of acute non-traumatic chest pain are complex, the severity of the condition varies greatly, and the specificity of symptoms is not high. Machine learning and intelligent auxiliary models can greatly shorten the time of clinical decision-making, and improve the accuracy of etiological diagnosis in patients with chest pain, reduce the rate of misdiagnosis and missed diagnosis, and provide a clear direction for further treatment.
This is an open label, single-arm, Phase 2 study to evaluate the efficacy and safety of Anti-FcRL5 CAR-T in subjects with relapsed and refractory multiple myeloma. A leukapheresis procedure will be performed to manufacture. Anti-FcRL5 chimeric antigen receptor (CAR) modified T cells. Prior to Anti-FcRL5 infusion subjects will receive lymphodepleting therapy with fludarabine and cyclophosphamide.
Deep brain stimulation (DBS) is an effective treatment for a variety of neurological and psychiatric disorders, with more than 200,000 patients implanted with DBS devices worldwide. Parkinson's disease is one of the typical indications.The clinical outcomes of DBS depends on the accurate implantation of the lead, and the identification of the lead locations is the basis for evaluating the effectiveness of the treatment. The aim of this study is to localize the implantation position of the lead based on postoperative MRI images and to reconstruct the relative spatial relationship between the lead and the stimulation target. By comparing with the lead position identified based on postoperative CT, this study will evaluate the accuracy of identifying the DBS lead position directly from MRI. This study may help to optimise the stimulation parameters and investigate the best stimulation targets for DBS patients.
This is a Phase 2 randomized, double-blind, placebo-controlled, multicenter study evaluating the efficacy and safety of AK117 or placebo, combined with azacitidine in patients with newly diagnosed higher-risk myelodysplastic syndromes (HR-MDS).
Patients with severe aortic stenosis combined with severe heart failure often miss the opportunity for surgery, and the prognosis is poor with drug therapy alone.In recent years, the emergence of transcatheter aortic valve replacement (TAVR) has brought new hope for these patients, and since its birth in 2002, TAVR has been widely used internationally, and its safety and efficacy have been confirmed by several large, prospective, randomized controlled studies. Levosimendan is a new type of positive inotropic drug. It not only enhances myocardial contractile force through calcium sensitization, but also activates K+ sensitive channel KATP on the membrane of vascular smooth muscle, relaxes the arteries and veins of the whole body, and reduces the front and back load of the heart, pulmonary vascular resistance and systemic vascular resistance. A series of studies suggested that for patients undergoing thoracotomy in various cardiac surgeries, regardless of whether the patients were accompanied by ventricular systolic dysfunction before surgery, the use of levosimendan resulted in significantly higher postoperative cardiac function and decreased mortality than the control group, and patients with preoperative LVEF < 40% benefited more. At present, there are no studies to clarify the regulatory effect of levosimendan on cardiac function after TAVR in patients with severe aortic stenosis complicated with cardiac insufficiency. This is a randomized controlled study. On the basis of basic drug therapy, the treatment group was given levosimendan to analyze the regulatory effect of levosimendan on cardiac function after TAVR.
The goal of this observational study is to evaluating myocardial stiffness in patients with heart failure with preserved ejection fraction (HFpEF) by intrinsic wave velocity propagation (IVP). The main questions it aims to answer are: - Whether myocardial stiffness assessed by IVP in patients with HFpEF Increased. - Whether IVP is related to the cardiac structure and function in patients with HFpEF. - What are the risk factors that may be associated with heart failure rehospitalization in patients with HFpEF? - Whether increased myocardial stiffness is a risk factor for heart failure rehospitalization. Participants will undergo transthoracic echocardiography to obtain conventional ultrasound parameters, and software post-processing analysis to obtained two-dimensional strain parameters and IVP, as well as general clinical data and laboratory test results. Clinical followed up was performed through electronic medical records or telephone interviews until patient rehospitalization for heart failure or discharge for one year.
This study aims to employ a longitudinal tracking research to investigate the effects of a visual perspective taking intervention on the development of theory of mind in children with autism. Additionally, the investigators seek to examine modifications in the neural mechanisms linked to facial emotion recognition in children both before and after intervention by using the functional Near-Infrared Spectroscopy (fNIRS) to record the relative changes in blood oxygen levels in the cerebral cortex with the oddball Face-Periodic Visual Stimulation (FPVS) paradigm.
