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 clinical study aims to evaluate the diagnostic performance of a new Epstein-Barr virus (EBV) C promoter methylation detection kit. All participants will undergo a series of diagnostic tests including VCA-IgA, EBNA1-IgA, and EBV-DNA assays. Additionally, nasopharyngeal swabs will be analyzed for EBV C promoter methylation. Confirmatory biopsy will be performed on all patients to establish a definitive diagnosis. This comprehensive approach seeks to assess the effectiveness of the methylation detection kit in a clinical setting.
The goal of this clinical trial is to learn if oxycodone hydrochloride works to manage pain in patients requiring mechanical ventilation. It will also assess the safety of oxycodone hydrochloride. The main questions it aims to answer are: 1. Does oxycodone hydrochloride effectively lower the CPOT (Critical Care Pain Observation Tool) score in mechanically ventilated patients? 2. What medical problems do participants have when using oxycodone hydrochloride? Researchers will compare oxycodone hydrochloride to remifentanil to see if oxycodone works better to manage pain in these patients. Participants will: - Receive either oxycodone hydrochloride injection at a dose of 0.03-0.2 mg/kg/h or remifentanil injection at a dose of 2-9 μg/kg/h. - Have their pain scores assessed every 15 minutes until the CPOT score is less than 3. After reaching the target pain score, assessments will be done every 4 hours. - Have their vital signs and monitoring data recorded. - Have analgesia and sedation scores recorded from days 1 to 7 after administration, with drug dosages adjusted based on pain scores. - Have the incidence of adverse reactions and changes in gastrointestinal function observed and recorded from days 1 to 7 after administration. - If extubated within 7 days, relevant data will be collected based on the time of extubation. - Be followed up on day 28 through the electronic medical record system to gather data on the extubation success rate and incidence of complications within the 28-day period.
Subarachnoid hemorrhage (SAH) is a common and extremely critical disease in neurosurgery. The mortality rate within 30 days of the onset of SAH is as high as 50%, and about 15% of SAH patients die without reaching the hospital. Nearly half of the survivors have severe neurological dysfunction, causing a huge burden to the families and society of the patients. Recently, the introduction of the "glymphatic-meningeal lymphatic vessels" drainage system has updated the current concept of intracranial cerebrospinal fluid circulation. After subarachnoid hemorrhage, a large number of blood components flooded into the subarachnoid space and entered the cerebrospinal fluid circulation, which directly affected the function of the lymphatic-meningeal lymphatic drainage system. Many preclinical animal studies have pointed out that the damage of the lymphatic-meningeal lymphatic drainage system is involved in the aggravation of cerebral edema, neuroinflammation and hydrocephalus after SAH, which ultimately leads to poor prognosis of patients. However, at present, the changes of the glymphatic-meningeal lymphatic drainage system after SAH have only been confirmed in animal models, and clinical evidence is lacking. With the development of imaging technology, many research teams have confirmed the functional changes of the lymphatic-meningeal lymphatic drainage system in Alzheimer's disease and Parkinson's disease by using different sequences of non-invasive MRI, such as 3D T2-FLAIR, DTI-ALPS and other sequences.
The Korotkoff Sounds（KS）, which have been in use for over a century, are widely regarded as the gold standard for measuring blood pressure. Furthermore, their potential extends beyond diagnosis and treatment of cardiovascular disease; however, research on the KS remains limited. Given the increasing incidence of heart failure (HF), there is a pressing need for a rapid and convenient prehospital screening method. In this study, we propose employing deep learning (DL) techniques to explore the feasibility of utilizing KS methodology in predicting functional changes in cardiac ejection fraction (LVEF) as an indicator of cardiac dysfunction.
This is a prospective observational cohort study to explore the effects of sleep quality and mental status on early postoperative recurrence and prognosis in patients with colorectal cancer.
Postoperative delirium is one of the common complications in the older aldults after surgery, which can lead to longer hospita stay，memory loss and reduced quality of life. There is currently no specific treatment. Therefore, it is important to prevent the occurrence of postoperative delirium. This study investigated the effect of intranasal insulin administration on the prevention of postoperative delirium and compared different doses of insulin to find a safe and acceptable method for preventing delirium.
The purpose of this study is to explore the efficacy, safety and cost-effectiveness of Xueshuantong (lyophilized) for the prevention of venous thromboembolism (VTE) in patients at risk of bleeding.
Postoperative nausea and vomiting (PONV) can lead to serious postoperative complications, but most symptoms are mild. Clinically important PONV (CIPONV) refers to PONV symptoms that have a significant impact on the patient's well-being and recovery. Present predictive systems for PONV are mainly concentrated on early PONV. However, there is currently no suitable prediction model for delayed PONV, particularly delayed CI-PONV. This study aims to develop and validate a prediction model for delayed CI-PONV using machine learning algorithms utilizing perioperative data from patients undergoing laparoscopic gastrointestinal surgery. All 1154 patients in the FDP-PONV trial will be enrolled in this study. Delayed CIPONV is defined as experiencing CIPONV between 25-120 hours after surgery. After selecting the modeling variables from 81 perioperative clinical features, six machine learning models are established to generate the risk prediction models for delayed CIPONV. The area under the receiver operating characteristic curve, accuracy, sensitivity, specificity, positive predictive value, negative predictive value, F1 score and Brier score are used to evaluate the model performance. Shape Additive explanation analysis was conducted to evaluate feature importance.
The goal of this prospective, observational study is to explore the value of dynamic monitoring of minimal residual lesions in driver mutated stage III NSCLC for disease recurrence and prognosis assessment. The main question it aims to answer is: 1) Whether MRD(Minimal residual disease) status can predict recurrence events in stage III driven-mutant NSCLC in advance
