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.
Cariogram and Cariostat will be used to assess the risk of caries in kindergarten children aged 3 years. Routine preventive measures will be taken for children at low risk of caries, and intensive intervention measures will be taken for children at medium and high risk. Routine measures will be taken for the control group. After one and two year, the prevalence of caries in the experimental group and the control group should be evaluated, and the cost-effectiveness evaluation will be conducted.
Tau protein has been identified as one of the key pathological features of Tau proteinopathies, such as Alzheimer's disease (AD), progressive supranuclear palsy (PSP), frontotemporal dementia (FTD). Tau protein-targeted PET imaging can detect the amount and distribution of Tau protein deposition in human body, and has great research and application value in the diagnosis and evaluation of Tau protein disease. This study will be the first to introduce a complete quantitative, repeatable detection and analysis method in China. For the SV2a tracer [18F]MNI-1126, cross-sectional evaluation of its imaging in patients with Tau protein-related diseases and normal controls will be carried out. Later, longitudinal clinical symptoms and two tracers will be evaluated in patients with Tau protein-related diseases and normal controls.([18F]APN1607 and [18F]MNI1126) Imaging follow-up to explore longitudinal changes in brain Tau protein deposition and synaptic density in Tau protein-related diseases, thus providing support for future clinical drug trials using imaging biomarkers.
Hysteroscopy is a gold standard method for evaluating the uterine cavity and diseases, which is gradually becoming a day-surgery in China. Propofol is one of the most commonly used intravenous anesthetics in clinic for hysteroscopic procedures, however high dose propofol bring some potential clinical safety hazards.In this study, the feasibility and safety of Etomidate combined with propofol(1:2) as improved scheme for hysteroscopic surgery will be evaluated.
Pancreatic cystic neoplasm (PCN) is a type of neoplastic lesion formed by the proliferation of pancreatic duct or acinar epithelial cells and retention of pancreatic secretions. The tumor can be located in the head and neck of the pancreas or the body and tail of the pancreas. Conventionally, open pancreaticoduodenectomy or open distal pancreatectomy was performed for patients with PCN locates either at the head or tail. In the ear of minimally invasive pancreatic surgery, when compared with open surgery, laparoscopic technology or Da Vinci robotic technology can avoid some open procedures limitations. Here we design this prospective randomized clinical trial to compare robotic surgery to laparoscopic surgery for the treatment of PCN and verify the safety and feasibility of both two minimally invasive procedures.
The first 1000 days, i.e., the earliest stage of life, is a unique period of opportunity to establish the foundations of human growth and health through the lifespan. In the recent decades, multiple studies have explored nutritional strategies for improving infant health through improving the nutritive and bioactive compositions in breast milk. For example, dietary fiber intake has been increasingly reported to benefit the health of the mother-infant dyad. However, the complex interplays among maternal diet, breast milk composition, infant gut microbiota and infant development are yet to be elucidated in a prospective cohort. In addition, the investigators' previous work has revealed unsatisfactory dietary patterns in Hong Kong lactating women, with clear inadequacy in fruit and vegetable intake. In this prospective cohort study, the investigators aim to recruit 100 healthy Chinese mother-child pairs. Data on maternal and infant dietary intake, breast milk composition, gut microbiota profile will be collected and the investigators will examine their associations with the health outcomes in infants. In addition, the influence of dietary factors and genetic predisposition on breast milk components and its associated benefits in the child will be interrogated. With the employment of multidisciplinary research approaches, cutting-edge biotechnologies and the omics platforms, this project will provide novel insights into the dietary factors and breastfeeding practices that are beneficial to the infant developmental trajectory, and the potential roles of breast milk composition in shaping infant's gut microbiota and the associated health impact in the long term. More importantly, the investigators hope to generate more solid scientific data to inform the public of the importance of maternal diet and the practical nutritional strategies to improve breast milk composition for the sake of the child.
Acute myeloid leukemia (AML) is a disease affecting older adults, although optimal strategies for treating such patients remain unclear. This prospective phase II, openlabel, multicenter study was designed to assess the efficacy and safety of two hematologic growth factors, recombinant human thrombopoietin (rhTPO) and granulocyte colonystimulating factor (G-CSF), in combination with decitabine, cytarabine, and aclarubicin (D-CTAG regimen) to treat older adults with newly diagnosed AML (Identifier: NCT04168138). The above agents were administered as follows: decitabine (15 mg/m2 daily, days 1-5); low-dose cytarabine (10 mg/m2 q12 h, days 3-9); rhTPO (15,000U daily, days 2, 4, 6, 8, 10-24 or until >50×109/L platelets); aclarubicin (14 mg/m2 daily, days 3-6); and G-CSF (300 μg daily, days 2-9). We concurrently monitored historic controls treated with decitabine followed by cytarabine, aclarubicin, and G-CSF (D-CAG) only. After the first D-CTAG cycle, the overall response rate (ORR) was 84.2% (16/19), including 13 (73.7%) complete remissions (CRs) and three (15.8%) partial remissions. This CR rate surpassed that of the D-CAG treatment (p < 0.05). Median overall survival (OS) time in the D-CTAG group was 20.2 months (range, 4-31 months), compared with 14 months in the D-CAG group, and 1-year OS was 78%. The proportion of those experiencing grade III-IV thrombocytopenia was significantly lower for D-CTAG (57.9%) than for D-CAG (88.4%; p < 0.05). Ultimately, the curative effect of adding rhTPO was not inferior to that of D-CAG, and D-CTAG proved safer for elderly patients, especially in terms of hematologic toxicity. A prospective phase III randomized study is warranted to confirm these observations.
