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 will comprise a randomized, parallel assignment, double blind, placebo controlled, single and multiple ascending dose, safety, tolerability and pharmacokinetic study of ZT002 in healthy participants.
The results of previous studies were used to assess the causal association between TK levels and stroke occurrence at 5 and 12 years of follow-up, respectively.
This study aims to retrospectively investigate the impact of body mass index on lung function metrics, e.g. FEV1%, FVC%, FEV1/FVC%.
The goal of this observational study is to understand the effects of anatomical factors, etiology, and complexity of anal fistula on the prognosis of patients undergoing anal fistula surgery within one year post-operation.The main question it aims to answer is: Which factors are indicative of the prognosis of anal fistula surgery? Which factors are landmark factors of anal fistulas? Participants who have already undergone anal fistula surgery at our hospital will receive outpatient and telephone follow-up to assess their prognosis.
This is a parallel and randomized-controlled clinical study aimed to identify the optimized size of atomized particles of 2% lidocaine that can provide the best topical anesthesia during ATI. To determine the effect of nebulization with different sizes of atomized particles of 2% lidocaine on cough, reaction, and comfort during ATI in patients with predicted difficult airway.
Background: This study aims to investigate the correlation between cirrhosis and hepatocellular carcinoma (HCC) recurrence after Liver Transplantation. Methods: The study retrospectively collected data enrolled from 519 HCC patients who underwent liver transplantation from two center(the First Affiliated Hospital, Zhejiang University School of Medicine and Shulan (Hangzhou) Hospital, January 2015 to December 2020), Based on important variables, 1:3 propensity score matching (PSM) were performed respectively.
Study Design and Participants This intervention study was conducted as a randomized controlled trial (RCT) aimed at investigating the effects of time-restricted feeding (TRF) on cardiovascular health markers among overweight male university students in Shenzhen, China. The study recruited male university students aged between 18 and 24 years, with a Body Mass Index (BMI) ranging from 24 to less than 28. All participants were free from severe psychiatric illnesses, metabolic syndrome, diabetes, alcoholic fatty liver disease, hyperthyroidism, or hypothyroidism. Inclusion criteria required participants to be non-smokers, not currently on any diet pills, and have no history of cardiovascular or metabolic diseases. Randomization and Intervention Fifty eligible participants were randomly assigned to either the intervention group (n=25) or the control group (n=25). The intervention group underwent a 6-hour daily TRF from noon to 6 P.M., while the control group did not participate in TRF but maintained their usual eating patterns. No restrictions were placed on the type or quantity of food consumed by participants in either group. Data Collection and Measures Body Composition and Anthropometry: Measurements included body mass index, body fat percentage, muscle mass, hydration levels, protein content, and visceral fat, all assessed using a bioelectrical impedance analysis scale (Mi Body Composition Scale 2 by Huami Technology). Waist circumference was manually measured by experienced nurses using a tape measure. Blood Pressure and Heart Rate: These vital signs were monitored using an arm cuff electronic blood pressure monitor (Panasonic EW3153), with the arm positioned at heart level to ensure accuracy. Measurements were taken after at least five minutes of seated rest. Nutritional Intake Although time-restricted feeding interventions do not usually change the content or quantity of dietary intake, the total daily intakes of energy, fat, protein, carbohydrate, cholesterol, and fibre were calculated using the Nutritionist Pro food analysis program. This was used to determine possible changes in the subjects' dietary composition as a result of the intervention. Compliance and Ethical Considerations The study protocol was approved by the Ethics Committee of the Seventh Affiliated Hospital of Sun Yat-sen University (Shenzhen), with the approval number KY-2022-101-01. All data were handled confidentially, and measures were taken to ensure high adherence and minimal loss to follow-up. Statistical Analysis Descriptive statistics such as range, mean, standard deviation, and percentages were used to describe the sample characteristics. To compare differences, the change from baseline levels was assessed to account for initial variability, employing an independent samples t-test for the analysis.
The goal of this clinical study is to evaluate the safety and efficacy of stenting for revascularization treatment of chronic middle cerebral artery (MCA) occlusion in patients with chronic MCA occlusion. The main questions it aims to answer are: 1. Whether stenting treatment can improve blood flow restoration in chronic MCA occlusion. 2. If stenting can reduce the rates of reocclusion. 3. How stenting affects the recovery of neurological functions in these patients. Researchers will compare the stenting group, which received stenting revascularization in addition to aspirin treatment, to the control group, which received only aspirin treatment to see if stenting treatment provides superior outcomes in terms of neurological function improvement and safety profile. Participants will: 1. Undergo full cerebral angiography to identify the occlusion site. 2. All participants will be monitored for post-procedure complications and neurological function using the Modified Rankin Scale (mRS) and National Institutes of Health Stroke Scale (NIHSS) before and after treatment. 3. Participants will be followed up for three months post-treatment to assess the long-term efficacy and safety of the stenting procedure.
This is a single-center, open Phase I clinical study, consisting of two parts: a Phase Ia study in healthy adult subjects and a Phase Ib study in patients with malignant solid tumors.
Reintubation is an adverse postoperative complication in patients with Type A aortic dissection (AAD) that correlates to poor outcomes. This study aims to analyze the risk factors associated with reintubation and to create a fully automated score model to predict the incidence of reintubation. A total of 861 patients diagnosed with AAD and undergoing surgical procedures in a single institution between January 2018 and October 2023 were selected in wuhan Union Hospital. Preoperative and postoperative informmation was used for seeking risk factors and build prediction model for postoperative reintubation. Finally, 5 risk factors wasidentified and a nomogram was established for predicting postoperative reintubation in patients with AAD.
