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.
Objective To prospectively determine the median effective dose (ED50) of propofol for inhibiting a response to laryngeal mask airway (LMA) insertion when combined with different doses of esketamine in female patients. Methods Fifty-eight female patients (aged 20-60, ASAⅠ-Ⅱ) scheduled for elective hysteroscopy were enrolled and randomly divided into two groups, one administered 0.2 mg/kg of esketamine (K1 group, n = 28) and the other 0.3 mg/kg of esketamine (K2 group, n = 30). The two groups received the corresponding doses of esketamine intravenously, followed by an intravenous injection of propofol (injection time was 30 s). The initial dose of propofol was 2 mg/kg, and the dose ratio of propofol in the adjacent patients was 0.9. If there was a positive reaction to LMA insertion, the dose ratio in the next patient was increased by one gradient, and if not, the dose ratio was decreased by one gradient. The median effective dose (ED50), 95% effective dose (ED95) and 95% confidence interval (95%CI) of propofol for inhibiting a response to LMA insertion in the two esketamine groups were calculated using a probit analysis.
Evaluation of the efficacy and safety of Serplulimab combined with bevacizumab biosimilar and HAIC in Advanced Hepatocellular Carcinoma (HCC) patients

The goal of this observational study is to investigate the correlation and quantitative relationship between the analgesic effect of fentanyl transdermal patches in cancer pain patients and their nutritional status.
This study is a multicenter, observational, single-arm real world study. The purpose of this study is to describe demographic and disease characteristics, treatment patterns, and clinical outcomes in the real-world setting among participants in China with relapsed/refractory multiple myeloma (RRMM) who have been treated with Equecabtagene Autoleucel. This study will use both prospective and retrospective data
The existing comprehensive diagnostic system for autoimmune pancreatitis (AIP) is complex, with multidimensional clinical information including morphological changes and a lack of specific biomarkers. Endoscopic ultrasound (EUS) can provide all the elements for morphological diagnosis of AIP, but the long learning curve and large observer differences make it difficult to popularize and promote. The cooperation units of the three regions in this project have found in the early stage that Klebsiella pneumoniae (KP) induced follicular helper T cells (Tfh) activation is an important mechanism of AIP, but the identification of pathogenic components of the strain and clinical validation need to be explored. We have established a national multicenter AIP queue in the early stage and extracted EUS audio-visual features to establish a scoring model, but intelligent assistance is still needed to improve efficiency. Therefore, we plan to integrate gut microbiota, Tfh activation markers, and EUS imaging features to establish an AI assisted multimodal diagnostic system for AIP. This study will collaborate across multiple centers to identify and validate the components that induce Tfh activation in KP bacterial cells, to extract EUS pancreatic ultrasound features and optimize artificial intelligence assisted diagnostic algorithms, and to establish and validate an artificial intelligence assisted multimodal diagnostic system based on clinical information, biomarkers, and EUS. The aim of this study is to provide new diagnosis and treatment evaluation methods for AIP with high accuracy, convenience, and easy promotion for clinical practice.
A multi-center, randomized controlled trial is being conducted to investigate the efficacy of a novel digital therapeutics (DTx) program that utilizes a cross-training approach between neurofeedback training and executive function training for pediatric patients (aged 6-12) diagnosed with ADHD. This gamified interactive program is designed to improve attention deficits and executive function impairments in pediatric patients with ADHD. It is delivered through an engaging iPad game in a home-based treatment format. Patients will be randomly assigned to one of three groups: medication alone, digital therapeutics alone, or a combination of both interventions. Subjects will undergo 30 treatment sessions over the 8-week period, with each session lasting 30 minutes. Investigators will reassess symptoms of ADHD, executive functions, and objective measures of attention at the end of the treatment. Additionally, questionnaires will be distributed to parents to gather their insights and feedback on the treatment approach. This innovative digital therapeutics approach is expected to improve ADHD symptoms individually and enhance therapeutic outcomes when used alongside conventional drug treatment regimens.
This is a randomized controlled trial that will be preceded by a safety trial focusing on the safety and efficacy of robotic telesurgery. The hypothesis is that robotic telesurgery has a non-inferior primary endpoint event rate to local laparoscopic surgery.
In 2023, the second Pediatric Acute Lung Injury Consensus Conference (PALICC-2) updated the diagnostic and management guidelines for Pediatric Acute Respiratory Distress Syndrome (PARDS). The guidelines do not provide sufficient evidence-based recommendations on whether prone positioning ventilation is necessary for severe PARDS patients. However, the effectiveness of Extracorporeal Membrane Oxygenation (ECMO) in treating severe PARDS has been fluctuating around 70% according to recent data from Extracorporeal Life Support Organization (ELSO). In 2018, the Randomized Evaluation of Sedation Titration for Respiratory Failure (RESTORE) study group conducted a retrospective analysis and concluded that ECMO does not significantly improve survival rates for severe PARDS. However, this retrospective study mainly focused on data from North America, with significant variations in annual ECMO support cases among different centers, which may introduce bias. With advancements in ECMO technology and materials, ECMO has become safer and easier to operate. In recent years, pediatric ECMO support technology has rapidly grown in mainland China and is increasingly being widely used domestically to rescue more children promptly. ECMO can also serve as a salvage measure for severely ARDS children who have failed conventional mechanical ventilation treatment. When optimizing ventilator parameters (titrating positive end expiratory pressure (PEEP) levels, neuromuscular blockers, prone positioning), strict fluid management alone cannot maintain satisfactory oxygenation (P/F<80mmHg or Oxygen Index (OI) >40 for over 4 hours or OI >20 for over 24 hours), initiating ECMO can achieve lung-protective ventilation strategies with ultra-low tidal volumes to minimize ventilator-associated lung injury.
Sporadic bilateral renal cell carcinoma (BRCC) is a rare situation of RCC. The treatment for BRCC is controversial and there is a lack of authoritative guidelines about the management of BRCC. The goal of this cohort study is to identify prognostic factors, construct predictive nomograms, and optimize management for sporadic BRCC patients. The main questions it aims to answer are: What are the factors influencing the prognosis of BRCC patients? What's the appropriate treatment for BRCC patients? Researchers will analysis the prognostic factors and compare the prognosis of BRCC patients receiving different treatments.
