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 goal of this study is planing to adopt intra-abdominal perfusion therapy of rmhTNF during radical colorectal cancer surgery to determine whether intra-abdominal therapy has an impact on postoperative intestinal function recovery, anastomotic leakage, postoperative bleeding, postoperative adhesion intestinal obstruction and other complications. On this basis, the effect of rmhTNF on postoperative peritoneal implantation metastasis and long-term survival was further studied. The main question it aims to answer is: To evaluate the safety and efficacy of rmhTNF in the treatment of peritoneal metastases in colorectal cancer. Participants will receive 1. Radical surgery: Surgical methods can be developed or endoscopic (including robotic surgery). Radical resection of colorectal cancer (corresponding resection of colon and rectum plus regional lymph node dissection, regional lymph node dissection including parenteral, intermediate and mesangial root lymph nodes) follows the principle of mesangectomy and tumorless operation. 2. Abdominal heat perfusion was performed twice: the first time, 5 million IUrmhTNF, dissolved in 30-50ml normal saline, was intraperitoneal heat perfusion into the surgical focus after the operation; the second time, rhatitrexed 2.5mg/m2 was injected into the abdominal cavity through thermoperfusion or drainage tube; 3. Postoperative systemic chemotherapy regimen: postoperative adjuvant chemotherapy should be started 3-4 weeks after surgery, and appropriately extended for patients with poor physique, but no later than 8 weeks after surgery. The chemotherapy regimen was determined by the clinician according to pathological stage, molecular typing, and risk factors, referring to the NCCN and CSCO guidelines.
To evaluate the safety of Fosaprepitant Dimeglumine Injection for the prevention of nausea and vomiting caused by tumor chemotherapy drugs, analyze the characteristics of the applicable population and clinical medication of Fosaprepitant Dimeglumine, evaluate the risk factors that may affect the efficacy of drug use, and compare the clinical benefits of different drug use modes.
The purpose of this study is to assess the efficacy and safety of Self-expanding Intracranial Stent (Tonbridge), by comparing the data obtained from Self-expanding Intracranial Stent (Zhuhai Tonbridge Medical Tech. Co., Ltd.) and LVIS/LVIS Jr. (MicroVention Europe SARL) for endovascular treatment of intracranial aneurysms.
Protein-bound uremic toxins (PBUTs) are important uremic toxins, represented by indoxyl sulfate (IS), derived from the fermentation of dietary proteins by gut bacteria. The purpose of this study was to study the changes of IS in maintenance hemodialysis patients, and to construct a metabolic kinetics model of IS clearance. The model was then used to estimate the clearance rate of indoxyl sulfate by hemoperage, and to verify the application value of the model. This study intends to collect a series of serum, dialysate and urine samples from maintenance hemodialysis patients receiving high-throughput dialysis or hemodialysis filtration, so as to clarify the variation rule of IS during various blood purification treatments. Furthermore, a three-compartment model of dialysis IS metabolism kinetics was constructed according to the IS clearance of dialysis and residual kidney, and the above model was verified internally and externally. Finally, the model's fit and predictive value were validated in a group of MHD patients treated with HP without residual kidney.
This study is designed to compare the anti-tumor activity as well as the safety and efficacy of FS-1502 versus T-DM1 in HER2-positive, unresectable locally advanced or metastatic breast cancer subjects previously treated with trastuzumab and taxane.
The purpose of this study is to explore the efficacy and safety of high- and low-dose radiotherapy (HD-RT/LD-RT) combined with envafolimab (I) in the treatment of metastatic solid tumors that have failed first-line immunotherapy or above.
This study plans to conduct a multicenter, observable and controlled cohort study to solid-tumor patients with receiving immunotherapy and to collect information about their treatment related efficacy, adverse reactions and health status to build a prospective disease cohort database based on patient reports, and then analyze the risk factors affecting the efficacy and prognosis of immunotherapy and the impact of immunotherapy on health status.It is expected to provide high-level evidence-based medical evidence for the selection of immunotherapy schemes for these patients, the precise prevention and health management of adverse reactions after immunotherapy, and the further improvement of survival prognosis of patients
The purpose of this study is to evaluate that milvexian is superior to placebo, in addition to standard-of-care, in reducing the risk of major adverse cardiovascular event (MACE) (the composite of cardiovascular [CV] death, myocardial infarction [MI], and ischemic stroke).
The goal of this observational study is to learn about the feasibility of enhanced three-dimensional water-selective cartilage (3D-WATSc) sequence in displaying the vessels of children's hip by magnetic resonance. The main questions it aims to answer are: - Could the images of enhanced 3D-WATSc sequence show the healthy side hip joint vessels in children? - Could the images of enhanced 3D-WATSc sequence show the vascular disease of the suffering side hip joint in children? Participants with unilateral hip disease will undergo the magnetic resonance examination including enhanced 3D-WATSc sequence. The pelvic plain film and magnetic resonance images will be collected and analysed. Researchers will compare the images of of the normal side with the images of the abnormal side to see if the enhanced 3D-WATSc sequence images could show the vascular disease of the suffering side hip joint in children?
In patients with acute hypoxemic respiratory failure whose diagnosis is not established after initial evaluation, obtaining a histopathological diagnosis may improve the patients' prognosis. In our previous retrospective-controlled study, transbronchial lung cryobiopsy (TBLC) can lead to an increased chance of establishing a diagnosis compared with transbronchial lung biopsy (TBLB), with an acceptable safety profile. Therefore, further prospective randomized controlled studies exploring whether TBLC leads to improved prognosis for such patients are warranted.
