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 clinical trial aims to learn about the efficacy of MLYAAT-1002® (a proprietary anti-aging complex, MLYAAT is short for "multi-layer anti-ageing technology" ) in female subjects who have newly received the rejuvenation treatment by comparing visual clinical scores, skin attributes measurement and image analysis.
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.
Hypoxia is a common adverse event during sedated hysteroscopy for assisted reproduction, and it is more likely to occur in overweight or obese patients. In sedated gastroscopy, the incidence of hypoxia with remimazolam is lower than that with propofol. The present study is a single-center, randomized, single-blind, controlled clinical trial. Overweight or obese patients undergoing sedated hysteroscopy for diagnosis and treatment, with ASA grade I or II, were selected as subjects and randomly divided into an experimental group and a control group, with 300 subjects in each group. Sedation induction and maintenance are performed using remimazolam or propofol combined with remifentanil, respectively, to compare the incidence of severe hypoxia during surgery between the two groups of patients.
Foreign data show that: 1807 tumor patients were followed up for 7 years, 33% of them died of heart disease and 51% of them died of the tumor itself. In China, the number of cancer patients undergoing chemotherapy is increasing rapidly every year. How to protect the heart of chemotherapy patients from the damage of chemotherapy drugs (especially anthracyclines) is a problem that clinicians must face.In order to further confirm the clinical efficacy and value of saffron total glycosides tablets in the protection of central function of breast cancer neoadjuvant patients with anthracycline based chemotherapy scheme, the project plans to follow up and observe the research of saffron total glycosides on the protection of cardiac function of breast cancer neoadjuvant patients with chemotherapy based on cardiac color ultrasound combined with myocardial zymography, and randomly group to confirm the effectiveness of saffron total glycosides tablets on cardiac protection, Based on the clinical observation and research on the effect of traditional Chinese medicine on the cardiotoxicity of anthracycline drugs, confirm its efficacy, explore the mechanism of cardiac protection, and explore the drug use method of synergism and toxicity reduction of anthracycline drugs in combination with this active ingredient.
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.
