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.
At present, the main therapies for myelodysplastic syndromes with ring sideroblasts (MDS-RS) are red blood cell and platelet transfusion, erythropoietin (EPO), androgen, and iron chelation therapy. Lenalidomide is an immunomodulator with multiple mechanisms, including direct targeting of MDS clones, immunomodulation, erythropoiesis restoration, and angiogenesis inhibition. A Phase III, randomized, placebo-controlled trial of oral azacitidine (AZA) in lower-risk MDS reported higher rates of hemoglobin and platelet hematological improvement in patients with AZA monotherapy. Therefore, this study intended to investigate the efficacy and safety of lenalidomide and sequential AZA in the treatment of refractory MDS-RS versus azacitidine monotherapy.
1. To retrospectively explore the feasibility of multi-dimensional heterogeneity imaging features of MRI in predicting the status of key gene mutations in high-grade gliomas; 2. To prospectively explore the correlation between multi-dimensional heterogeneous MRI image features and prognosis of high-grade glioma patients.
This study aims to evaluate the feasibility and safety of Cold snare polypectomy for removing 5-9mm small intestinal polyps in patients with Peutz-Jeghers Syndrome (PJS),in order to provide some reference for clinical strategy of endoscopic treatment of small intestinal polyps in PJS patients, and may prolong the follow-up period of PJS patients Intervals.
Colorectal cancer is a common digestive tract tumor in China. At present, laparoscopic surgery has become the classic operation of colorectal cancer surgery compared with the traditional open abdominal surgery. Although laparoscopic surgery has many advantages, such as less pain, faster recovery and so on. However, relevant studies have shown that postoperative pulmonary complications are more common in patients undergoing Laparoscopic Colorectal Surgery, which contribute to significant increases in morbidity, mortality, length of postoperative hospital stay and medical consumption. The incidence of pulmonary complications after abdominal surgery has been reported to be between 9% and 40%. The reduction in pulmonary volume and respiratory muscular activation after major abdominal surgery due to surgery-related shallow breathing, pain, long-term bed rest, mucociliary clearance disorder, and diaphragmatic dysfunction may be the main causes of postoperative pulmonary complications. Numerous studies have demonstrated physiological improvement related to prone positioning. Prone positioning consists of placing a patient face down. Prone positioning has been used for to improve oxygenation in patients who require invasive mechanical ventilation for acute respiratory distress syndrome (ARDS). It has also been applied to non-intubated patients with acute respiratory failure (ARF), to improve oxygenation and delay or even avoid the need for invasive ventilation. So, the purpose of this study is to observe whether preoperative prone position training can reduce the incidence of pulmonary complications after laparoscopic colorectal cancer surgery.
The etiology and specific pathogenesis of many cardiovascular diseases such as coronary atherosclerosis, cardiomyopathy, atrial fibrillation, and stroke are still unclear. Improving diagnosis and treatment, clarifying the pathogenesis, and providing scientific basis for the prevention and treatment are hot research topics in the study of cardiovascular and cerebrovascular diseases. This study intends to collect clinical data and biological specimen data of patients with cardiovascular and cerebrovascular diseases who meet the inclusion and exclusion criteria, and use multi-omics technology to deeply understand the pathogenic mechanisms of cardiovascular and cerebrovascular diseases and provide new ideas for specific and individualized treatment of patients with cardiovascular and cerebrovascular diseases, to construct early predictive prognostic models and provide a basis for effective treatment of clinical practice in patients with cardiovascular and cerebrovascular diseases.
Post-transplantation cyclophosphamide (PTCY) is considered as major graft versus host disease (GVHD) prophylaxis. In our previous study, the investigators demonstrated that the standard dose PTCY of 50mg/kg with tacrolimus and post-engrafted low-dose anti-thymoglobulin (ATG) achieved low incidence of acute GVHD. More recently, it has been shown that reduced dose of PTCY of 40mg/kg is considered with similar efficacy as GVHD prophylaxis, In this study, a multi-center randomized comparison is planned to evaluate the clinical outcome of GVHD prophylaxis of PTCy 40 versus 50.
The goal of this clinical trial is to prove the benefit of intrapulmonary percussive ventilator in healthy volunteers. The main questions are: - How can intrapulmonary percussive improve lung function？ - What is the subjective feeling through intrapulmonary percussive? Participants will be undergoing treatment of intrapulmonary percussive. Then they will be assessed for lung function and EIT before and after intrapulmonary percussive.
This study will construct a retrospective-prospective long-term follow-up cohort and management system for aortic dissection through a multicentre collaborative network. This study aims to investigate the disease characteristics, progression patterns, clinical features, natural course and factors affecting the disease course and prognosis of patients with aortic dissection by retrospectively collecting data and prospectively enrolling patients.
The goal of this clinical trial is to evaluate the efficacy and safety of Telitacicept for the treatment of connective tissue disease-associated thrombocytopenia.
Previously, preliminary results, from a subgroup analysis of STARS-RC03 (NCT04906044) conducted by our research team, showed that the 6-cycles consolidation chemotherapy combining with anti-PD-1 therapy had a better tumor regression advantage with a restricted safety profile contrasted with 3-cycle counterparts. Herein, we designed this study to further evaluate the short-term efficacy (such as pCR rate, R0 resection rate, etc.) and long-term survival (including DFS, OS, etc.) of 6-cycles consolidation therapy.
