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.
This is an prospective study to evaluate the safety and efficacy of naxitamab monotherapy or combined with chemotherapy or combined with chemotherapy and checkpoint inhibitor in the treatment of pediatric high-risk and refractory/relapsed neuroblastoma in Sun Yat-sen University Cancer Center.
The goal of this clinical trial is to explore the pathophysiological effects of the persistently colonized microbiome in irritable bowel syndrome (IBS) patients. The main questions it aims to answer are: Question 1: the microbiome difference of the biofilm between IBS and healthy patients. Question 2: the metabolic product patterns between IBS and healthy patients. Participants will need to take a colonoscopy examination, two gut mucosal biopsy samples will be collected during the examination. Researchers will compare the IBS and healthy control groups to see if there was the disease-specific pattern in the microbiome and metabolic product of the biofilm.
Acute respiratory distress syndrome (ARDS) is a clinical syndrome caused by intrapulmonary and/or extrapulmonary causes, characterized by intractable hypoxemia. Studies have shown that the sympathetic nervous system is over-activated in patients with acute respiratory distress syndrome. A large retrospective study showed a reduction in mortality in ARDS patients treated with oral β1 blockers before admission, and this beneficial effect of β1 blockers applies to ARDS patients with or without cardiac disease. Esmolol is an ultra-short-acting selective β1 receptor blocker. Previous studies have shown that esmolol can improve oxygenation and reduce the levels of inflammatory cytokines and exudate proteins in bronchoalveolar lavage fluid, thereby alleviating pulmonary injury. According to the literature and our previous clinical observations, we made the following hypothesis: When Estolol is applied to various ARDS patients undergoing mechanical ventilation in ICU, it can control the heart rate by inhibiting β-adrenergic receptor, which can ultimately improve the oxygenation index of patients and shorten the mechanical ventilation time. This project intends to include ARDS patients with optimal hemodynamic treatment for 24 hours, whose heart rate is still ≥95 beats/min after conventional treatment, but ≤120 beats/min. They are randomly divided into control group and Esmolol treatment group to study the effects of esmolol on patients' oxygenation index, mechanical ventilation time, hemodynamics, function of various organs and inflammation level. The aim of this study is to optimize the treatment of ARDS patients.
This is a single-center, open-label clinical study of anti-CEA-CAR-T cells for CEA+ patients with locally advanced and/or metastatic solid tumors. In this study, a single-dose regimen was designed, and the investigator had the discretion to decide whether the patient received more than once CAR T-cell therapy.This study intends to include CEA+ patients with locally advanced and/or metastatic solid tumors.They will take the anti-CEA-CAR-T cell transfusion after a screening period, mononuclear cell (PBMC) collection, bridging therapy if necessary, and lymphocyte clearance pretreatment period.
Radical operation of esophageal cancer is complicated and traumatic, and ventilation with one lung in lateral position and ventilation with both lungs after supine position requires long-term tracheal intubation and ventilator-assisted ventilation, and the incidence of postoperative pulmonary complications is high.
To manage the ST-segment elevation myocardial infarction (STEMI) caused by plaque rupture, triggers platelet activation/aggregation and thrombin generation, requires dual (platelet and coagulation) pathway inhibition. However, triple antithrombotic therapy with standard dual antiplatelet therapy (DAPT) and oral anticoagulant (OAC) in the STEMI setting is a challenge, since that increase in potential risk of bleeding. Although the incidence of left ventricular thrombus (LVT) formation after STEMI decreased in modern reperfusion therapy, including primary percutaneous coronary intervention (PCI), remains at 4% to 26%, especially that complicated by anterior STEMI. The recommendation of an OAC prophylactic therapy for preventing LVT formation in current STEMI guidelines is limited. How to optimize antithrombotic therapy to balance the bleeding-thrombotic profile, and prevent LVT formation is challenging, since insufficient evidence is available from randomized trials. Century Clot analyzer is point-of-care testing that could assess the coagulate state: normal, hypo-coagulable, or hyper-coagulable states according to clot rate (CR) value. Whether Century Clot-guided rivaroxaban prophylactic therapy (2.5 mg twice daily, if the hypercoagulable state, defined as CR ≥24) in combination with standard DAPT could reduce LVT formation without increasing major bleeding is uncertain.
To achieve the stent optimization following "Keep It Simple and Safe" coronary intervention is recommended. A protocol of Joint Inflation with Nominal-pressure and Stability (JINS) approach in coronary drug-eluting stent (DES) implantation by intracoronary imaging (ICI) guidance could provide additional benefits in reducing unnecessary radiation exposure, and post-dilatation balloon angioplasty-related complications.
This study intends to include hypertrophic cardiomyopathy patients over 18 years old who underwent cardiac surgery in our hospital. Patients were divided into medication group and control group according to the use of gastrodin during operation. The patients ' myocardial tissue samples were collected, the postoperative prognosis data were observed and recorded, and the data were analyzed. The degree of myocardial tissue cell damage and postoperative clinical outcomes were compared between the two groups.
The purpose of the study was to evaluate whether individualized general anesthesia with target-controlled infusion could help patients wake up early for extubation and reduce the incidence of postoperative complications, and to investigate the effectiveness and safety of its application in patients undergoing cardiac surgery.
Previous studies have shown that perioperative intravenous iron has a beneficial effect on patients with perioperative anaemia. To assess whether a combined iron supplementation regimen can reduce perioperative allogeneic blood transfusions in patients with iron deficiency anaemia undergoing major cardiac surgery under haemodynamic anaesthesia, a multicentre randomised clinical trial (CIPAT study) will be conducted. In the CIPAT study, patients undergoing elective major cardiac surgery under general anaesthesia will be randomly allocated to a control group and a combined iron supplementation group. Patients in the combined iron supplementation group will receive a combination iron supplementation regimen of iron sucrose in combination with Human Erythropoietin and vitamin C three times in the week prior to surgery, while patients in the control group will receive the same dose of placebo three times in the week prior to surgery. The primary endpoint is the volume of allogeneic erythrocyte infusion from the start of surgery to 5 days postoperatively. It is hypothesised that patients in the combined iron supplementation group will have fewer perioperative allogeneic red blood cell transfusions than those in the control group.
