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 main objective of this study is to evaluate the therapeutic effectiveness of the internal limiting membrane (ILM) peeling and translocation surgery compared to the conventional surgical approach for treating large idiopathic macular hole (IMH) through a well-designed prospective randomized controlled clinical trial. This study aims to compare the new surgical approach to the conventional approach in terms of improving visual function, promoting macular retinal anatomical healing, and enhancing patients' quality of life. By conducting this prospective clinical trial, establishing a database, and generating clinical reports and evidence-based medicine on the therapeutic efficacy of the ILM peeling and translocation surgery for large IMH.
In this study, a new post-processing image technology - radiomics is used to screen out parameters of CT and MRI images, which could effectively evaluate the efficacy and prognosis of immunotherapy plus targeted therapy for soft tissue sarcoma (STS). A reliable and effective model for predicting the prognosis of STS will be established based on the radiomic parameters combined with traditional imaging, histophiological, whole exome sequencing (WES) results, inflammatory indicators and changes in the number and function of lymphocyte subsets before and after medication. Patients with advanced STS who may benefit from the combination therapy can be found out by this model.
The goal of this observational study is to evaluate the treatment effect and health economic impact of oral nutritional supplements(ONS) in hospitalized patients with nutritional risk. The main questions it aims to answer are: - To evaluate the effect of ONS on clinical outcomes in hospitalized patients with high nutritional risk - To evaluate the health economic impact of ONS in hospitalized patients with high nutritional risk Data was collected from patients admitted to peking union medical college hospital between January 1, 2018 and December 31, 2020. The inclusion criteria were as follows: (1) age≥18 years old; (2)length of hospital stay≥3days; (3) Only ONS was used as enteral nutrition or no enteral nutrition was received. Exclusion criteria were: (1) age<18; (2) length of hospital stay<3 days; (3) the patients who received enteral nutrition other than ONS (such as tube feeding); (4) emergency admissions; (5) the patients who transferred from other hospitals; (6) pregnancy or lactation We collected the following data through the hospital big data query and analysis system: 1. Basic information: gender, age, height, weight, medical insurance, etc. 2. Clinical information: admission paths, admission time, admission departments, discharge time, discharge unit, length of stay, mode of payment； 3. Disease Information: admission diagnosis, disease coding at admission, the first discharge diagnosis, the coding of first discharge diagnosis, the second discharge diagnosis, the third discharge diagnosis, outcome (recovery, improvement, not cured, death, transfer to another hospital) 4. Operation information: surgical name, surgery code, 5. oral nutritional supplement: drug names, unit price 6. laboratory examination: hemoglobin, albumin, prealbumin 7. hospitalization costs: total cost, self-pay cost, other cost, the type of medical insurance； Researchers will compare ONS group to see the clinical outcomes and health economic impact.
To evaluate the efficacy and safety of selinexor combined with R-GDP regimen in the treatment of patients with TP53-altered relapsed or refractory B-cell lymphoma.
This study aims to observe and explore the efficacy and safety of Anlotinib combined with penpulimab in the treatment of radioiodine refractory differentiated thyroid cancer with first-line resistance to angiogenesis inhibitors, and to summarize the treatment experience of population.
Scoliosis correction surgery is associated with severe pain. Patients after scoliosis correction surgery usually require high dose opioids and long duration analgesia, which may increase side effects and drug tolerance. In a recent trial, mini-dose esketamine and dexmedetomidine combination as a supplement to sufentanil significantly improved analgesia and subjective sleep quality after spinal correction surgery without increasing adverse events; however, the proportion of patients with moderate-to-severe pain remained high. The authors speculate that increasing esketamine dose in the combination may further improve analgesic effects.
A prospective, single-center, first in man study to evaluate the safety and efficacy of WeFlow-EndoSeal Aorta Vascular Plug System manufactured by Hangzhou Endonom Medtech Co., Ltd. for the dissecting aneurysm of descending thoracic aorta after aortic dissection repair.
This is a functional near infrared spectroscopy (fNIRs) study designed to screen for risk of falls after diagnosis of stroke and initial intervention.
Acute myocardial infarction (AMI) is one of the most important diseases threatening human life. The existing MI prognosis prediction scales mostly predict the incidence of death, recurrent MI and heart failure through 6-8 clinical text indicators, and the data are collected relatively simply. Myocardial remodeling, as an adverse pathological change that can start and continue to progress in the early stage after myocardial infarction, is the main pathological mechanism of heart failure and death. However, there is no quantitative early-warning model of myocardial remodeling, and the clinical guidance of early intervention is lacking. Our previous study found that cardiac magnetic resonance imaging can accurately quantify the necrotic area and recoverable myocardium in the edematous myocardium after myocardial infarction. In this study, machine learning algorithm, variable convolution network (DCN) and capsule network (capsnet) are used to build a new neural network architecture. Structural feature extraction of multi-modal clinical image data such as MRI and ultrasound is realized. Combined with the established database of 3000 patients with myocardial infarction, the multimodal feature matrix will be constructed, and a variety of classifiers such as support vector machine (SVM) and random forest (RF) will be used for quantitative prediction of myocardial remodeling, and the effects of different classifiers were evaluated. It is expected that this project will establish a quantitative early warning model of myocardial remodeling after acute myocardial infarction in line with the characteristics of Chinese people. The same type of data outside the database will be used for verification to establish an efficient and stable early warning model.
Venovenous extracorporeal membrane oxygenation (VV-ECMO) is a salvage treatment for severe acute respiratory distress syndrome (ARDS). With the large-scale implementation of VV-ECMO in critical care medicine departments in China, significant progress has been made in treating severe ARDS. However, the patient mortality rate remains high. The pathophysiological essence of ARDS is an imbalance between the body's oxygen supply and demand, causing tissue and cell hypoxia, organ dysfunction, and even death. The VV-ECMO treatment process still requires mechanical ventilation assistance. However, inappropriate mechanical ventilation settings can lead to ventilator-related lung injury (VILI). In recent years, mechanical power has gradually attracted everyone's attention and is considered the cause of VILI. The transpulmonary mechanical power is more accurate to the energy directly performed to the lung tissue. Transpulmonary mechanical energy has a specific value in judging the prognosis of mechanically ventilated patients, but its clinical significance in treating patients with VV-ECMO is unclear. This study aimed to explore the value of transpulmonary mechanical power in predicting the prognosis of patients with severe ARDS patients treated with VV-ECMO.
