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.
Endovascular treatment（ET）is an effective therapy for acute ischemic stroke(AIS) with great vessel obstruction. However, acute complications such as high postoperative perfusion injury, hemorrhagic transformation and restenosis resulted in functional independence in only about 50% of patients 90 days after interventional surgery. Therefore, it is very important to protect the neurologic function after emergency endovascular treatment. The investigators' previous studies have shown that combined with intravenous thrombolytic therapy and remote postconditioning（RIPC）can significantly improve the neurological impairment and short-term and long-term prognosis in patients with acute stroke. In this multicenter, randomized controlled trial, the investigators assumed patients with acute ischemic stroke who had successfully revascularization after ET might benefit from RIPC as well. Patients in the RIPC group had five cycles of 5-min cuff inflation followed by 3-min deflation to the bilateral upper arm after ET. The primary endpoint measure was the proportion of patients with a favorable recovery of nerve function deficient assessed by Modified Rankin Scale （mRS≤2） 90 days after surgery. Secondary endpoints included the following: (1) Symptom endpoints: Neurological intelligence and function scores, postoperative hemorrhagic transformation rate, etc. (2) Blood index test: postoperative inflammatory factors, neuron-specific enolase (NSE) and other indicators. (3) Imaging endpoints: MRI-FLAIR , TCD, etc.
An open, multicenter, phase Ib/II study to evaluate the efficacy, safety and pharmacokinetics of CT041 autologous CAR T-cell injection in patients with advanced gastric/ gastroesophageal junction adenocarcinoma and pancreatic cancer
A multiple-center study on the effect of different ways of lymph node dissection on the prognosis of less than 3cm ground glass nodules with more than solid components
This is a prospective observational clinical trail which will recruit 1000-1500 participants over 65 years with frailty and acute coronary syndrome (ACS) in Beijing Friendship hospital. The investigators will conduct frailty assessment (FRAIL scale, CFS, SPPB), comorbidities, functional status (Barthel index, ADL, IADL), nutritional risk (MNA-SF), and then observe the clinical outcomes of elderly ACS participants with frailty. Then, the investigators will follow-up these participants separately in 1,3,6 and 12months, the anticipate follow-up time is 1 year. According to the follow-up results, investigators will evaluate the impact of frailty and other senile syndromes on the short-term and long-term prognosis of ACS, and develop a scoring system for the prognosis evaluation of elderly ACS participants.
The study was designed to investigate the correlation between perioperative adverse cardiovascular events and the degeneration of sensory nerves in patient diagnosed with type 2 diabetes mellitus, undergoing elective non-cardiac surgery.
The aims of this study are 1) to compare the efficacy and safety of conventional myotomy (long myotomy) and modified myotomy (short myotomy) in the treatment of type I/II achalasia patients diagnosed according to Chicago Classification; 2) to compare the efficacy and safety of conventional myotomy (circular myotomy) and modified myotomy (full-thickness myotomy) in the treatment of type I/II achalasia patients; 3) to compare the efficacy and safety of conventional myotomy (non-tailored myotomy) and modified myotomy (tailored myotomy) in the treatment of type III achalasia patients.
This is a randomized, multicenter, open-label, Phase 3 study to evaluate the efficacy and safety of ICP-022 versus Chlorambucil plus Rituximab in subjects with Previously Untreated Chronic Lymphocytic Leukemia.
Premature coronary heart disease (CHD) refers to the onset of myocardial infarction in men < 55 years old, women < 65 years old. At present, researches on early-onset coronary heart disease mostly focus on its risk factors and clinical characteristics, but there is no relevant research on the relationship between early-onset myocardial infarction and atherosclerosis.
This study is the first to investigate the relationship between the changes of serum calcium and orphanin fq and the changes of cognitive function in patients with diabetes.To general anesthesia surgery of patients with diabetes as research group (group A), and to the non-general anesthesia surgery of diabetic patients as control group (group B), and then measured preoperative serum calcium ion concentration in patients with general anesthesia, inflammatory factor and solitary brown peptide content, intraoperative calcium ion concentration in serum, inflammatory factor and solitary brown peptide content, and postoperative serum calcium ion, inflammatory factor and solitary brown peptide content.Postoperative cognitive function were evaluated in both groups.Finally, the two groups of patients were screened and the inconsistent medical records were eliminated.Observation indicators: Endothelin, C-reactive protein, nitric oxide, interleukin-6, calcium ion concentration, orphanin fq concentration, glycated hemoglobin value and blood glucose value were observed before, during and after operation.The cognitive function of diabetic patients after surgery was observed. The cognitive function was evaluated with the cognitive function assessment scale 24 hours after surgery, respectively, and scores were obtained.Expected results: The comparison of clinical data between the control group and the study group showed that the cognitive function of patients in the study group was lower than that in the control group; the analysis showed that the serum content of orphanin fq in the study group was higher than that in the control group, the content of related inflammatory factors was higher than that in the control group, and the content of calcium ion was lower than that in the control group, and the differences were statistically significant.The results showed that when the cognitive function decreased, the content of orphanin fq increased, the corresponding inflammatory factors increased and the content of calcium decreased, indicating that the change of consciousness state and cognitive function were correlated with the orphanin fQ system.
Early mobilization is considered as an important strategy to enhance postoperative recovery. However, direct association between very early mobilization and improved recovery needs randomized control trials to prove. This study proposes the program of walking out from operating room (WOFOR) after surgery, which means that encouraging patients to walk out from the operating room and return to the ward by walking under the condition of painlessness, clear consciousness and normal muscle strength of lower limb. The aim of this randomized controlled trial is to investigate the effect of WOFOR on the postoperative recovery of patients undergoing laparoscopic colorectal surgery.
