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 objective of the study is to construct a noninvasive approach 68Ga-THP-Trop2 VHH PET/CT to detect the Trop-2 expression of tumor lesions in patients with Solid tumors and to identify patients benefiting from Trop-2 targeting antibody-drug conjugate treatment.
Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by social impairment, repetitive behaviors, and narrow interests. With advancements in diagnostic techniques, the prevalence of ASD has been increasing annually. However, due to its complex and diverse etiology, there is no definitive consensus on the pathogenic mechanism of ASD. Numerous studies indicate that genetics, environment, and other factors play crucial roles in the onset of ASD. Vitamin A (VA) exerts its effects in the body through its active metabolite, retinoic acid (RA), which regulates the transcriptional activity and expression of downstream genes by binding to retinoic acid receptors (RARs/RXRs). Triggering Receptor Expressed on Myeloid Cells 2 (TREM2) is an immunoglobulin-like receptor present on microglial cells, with functions including inhibiting the production of inflammatory factors and engulfing apoptotic neurons. Recent foreign studies show a significant decrease in TREM2 levels in the brain tissue of ASD patients. However, there is limited research on the relationship between TREM2 and ASD. In our previous animal experiments, we observed a reduction in TREM2 in the prefrontal cortex of the brain in ASD model rats. Administering overexpressed TREM2 improved autism-like behavior in ASD model rats, and supplementing RA upregulated the expression of RA-RARĪ± and TREM2, modulated microglial cell activation, and improved autism-like behavior in rats. Therefore, we believe that the RA/RARĪ± pathway regulates the TREM-2 signaling pathway, mediating changes in microglial cells, and TREM2 may be involved in the pathogenesis of ASD. Soluble TREM2 (sTREM2) is formed by the extracellular domain shedding of TREM2 under the action of ADAM protease. Research indicates that the expression of sTREM2 can be detected in cerebrospinal fluid and plasma. However, the connection between VA, sTREM2 levels, and the behavioral and developmental levels of children with ASD remains unclear and requires further clinical research to validate. This will help deepen our understanding of TREM2 expression in ASD, its potential biological functions, and the role of RA.
The goal of this observational study is to learn about the distribution of bioimpedance vector of healthy neonates in China in health conditions. The main question it aims to answer are:whether the distribution of bioimpedance vector of healthy neonates in China is correspond to that in other countries.Participants will be measures by NUTRILAB impedance analyzer (Akern, Florence, Italy).
This study aims to evaluate the safety and efficacy of a three-dimensional navigation intracardiac guidance kit to perform atrial septal puncture in patients requiring catheter ablation, which will be compared with procedures using traditional kit for atrial septal puncture.
This is an open-label, single-arm, phase 2 study. The purpose of study is to evaluate the feasibility and safety of hepatic arterial infusion chemotherapy combined with lenvatinib and cadonilimab as conversion therapy for unresectable hepatocellular carcinoma.
The goal of this observational clinical trial is to evaluate the value of circulating tumor cell detection in the early diagnosis of malignant pulmonary nodule. The main questions it aims to answer is: the sensitivity and specificity of peripheral blood circulating tumor cell detection in differentiating benign and malignant pulmonary nodules (<3cm). Participants will be asked provide 4mL of peripheral blood for the test.
This study intends to recruit ES-SCLC patients with response to standard first-line chemo-immunotherapy to assess the safety of receiving different doses of consolidative thoracic radiotherapy.
This Randomized controlled intervention study recruited patients diagnosed with ST-segment elevation myocardial infarction (STEMI). A total of 240 patients were enrolled in either Henagliflozin group or control group. Patients in Henggliflozin group will be given by oral administration of Henggliflozin for 6 months post acute myocardial infarction. Prior to procedure, dynamic changes in myocardial enzymes were monitored. Major cardiovascular events, including non-fatal myocardial infarction, all-cause death, revascularization due to angina, and hospitalization for acute heart failure. This study aims to assess the impact of Henggelizin intervention on the reduction of myocardial infarction size (evaluated by cardiac enzyme) and improvement of left ventricular remodeling in patients with ST-segment elevation myocardial infarction.
Although definitive chemoradiotherapy (CRT) is the standard treatment option for unresectable locally advanced esophageal cancer, elderly patients tolerate intravenous concurrent CRT less well with age and comorbidities. Previous trials have demonstrated that CRT with oral S-1 was tolerable and provided significant survival benefits over radiotherapy alone in elderly patients with esophageal squamous cell carcinoma (ESCC). However, as high as 54% of patients with elderly ESCC experienced locoregional or distant recurrence after CRT. Therefore, a more effective regimen for older patients is needed. Immune checkpoint inhibitors targeting PD-1/PD-L1 have shown substantial clinical benefits in advanced esophageal cancer. Recently, the combination of immunotherapy with CRT has emerged as a promising strategy to improve clinical outcomes in locally advanced esophageal cancer. The aim of this study was to evaluate the efficacy and safety of toripalimab (an anti-PD-1 antibody) after concurrent CRT in elderly patients with locally advanced ESCC.
This is a large observational cohort study to assess the impact of COVID-19 infection on pregnancy outcomes and offspring health.
