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 study is a retrospective study of clinical specimens. The study subjects were patients with esophageal cancer who received immunotherapy. Tumor tissue specimens surgically removed from patients before treatment will be collected primarily. In situ immunohistochemistry and multicolor immunofluorescence will be performed. We hypothesize that there are differences in lipid metabolism-related proteins in tumor tissues and immune cells in the preexisting tumor microenvironment in patients with esophageal cancer prior to immunotherapy, and that there is a link between such differences and the efficacy of immunotherapy.
The goal of this retrospective multicentre cohort study is to examine the association between receipt of sivelestat and improvement in oxygenation among patients with acute respiratory distress syndrome (ARDS) induced by COVID-19. We used propensity score matching to compare the outcomes of patients treated with sivelestat to those who were not. The primary outcome was the PaO2/FiO2 ratio on Day 3. Secondary outcomes included 28-day mortality, alive and ICU-free days within 28 days, non-mechanical ventilation time within 28 days, the lengths of stay in the ICU and hospital, proportion of patients requiring extracorporeal membrane oxygenation (ECMO), proportion of patients undergoing endotracheal intubation or tracheotomy, and incidence of adverse events (AEs) or severe adverse events (SAEs).
To compare the clinical and postoperative analgesic effects of hydromorphone combined with ropivacaine and ropivacaine alone in quadrangular muscle block for open inguinal hernia in elderly patients.
The "adjacent bed effect" caused by anxiety leads to poor recovery of participants after ovarian chocolate cyst surgery, including pain and quality of life, and affects participant satisfaction with the hospital.
The purpose of this study was to evaluate the safety and efficacy of intravascular high-pressure cut balloon catheter compared to cut balloon catheter during PCI, and to support product registration and clinical application.
The primary objective of the study is to evaluate the pharmacokinetics of rocatinlimab after single subcutaneous (SC) administration in healthy Chinese participants.
To evaluate the efficacy and safety of Wedge NC Scoring Balloon Dilatation Catheter for dilating coronary stenosis during PCI in comparison with a similar product on the market.
The goal of this observational study is to learn about the role of MRI evaluation based on FVH-DWI mismatch principle in preoperative evaluation of endovascular thrombolectomy. The main questions it aims to answer are: - The consistency between MRI and perfusion examination in determining EVT indications. - The consistency of functional independence rate between patients screening with MRI and perfusion.
A multicenter, randomized, double-blind, placebo-controlled clinical trial was designed. The study included two experimental groups (low-dose ZKY001 eye drops group and medium-dose ZKY001 eye drops group) and a placebo control group, with 60 subjects in each group.
This trial was a randomized, double-blind, sham-controlled trial.Thirty patients with post-stroke dysphagia were randomly assigned to the repetitive transcranial magnetic stimulation(rTMS) group (n=15) or sham rTMS group (n=15). Both groups received conventional swallowing rehabilitation, and in addition, the rTMS group received 5hz repetitive transcranial magnetic stimulation on the healthy side. Swallowing function was assessed at admission and after two weeks of treatment using the the Standardized Swallowing Assessment (SSA), the Penetration-Aspiration Scale (PAS), the Fiberoptic Endoscopic Dysphagia Severity Scale(FEDSS), the Functional Oral Intake Scale (FOIS), and the functional near-infrared spectroscopic(fNIRS).
