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.
In the past 30 years, the blood lipid level of the Chinese population has gradually increased, and the prevalence of dyslipidemia patients has increased significantly. Hyperlipidemia is a disease caused by abnormal blood lipid levels, also known as abnormal lipid metabolism. Common clinical indicators include total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL) and high-density lipoprotein ( HDL).The number of patients with abnormal blood lipid levels in China accounts for as high as 40% of the total. It is estimated that between 2010 and 2030,cardiovascular disease events will increase by 9.2 million, which seriously endangers human health and becomes a high risk factor for various cardiovascular diseases, such as atherosclerosis. One of the pathological foundations of atherosclerosis is that abnormal lipid levels in the body cause a large amount of lipid to be deposited in the arterial endothelial matrix, which is phagocytosed by smooth muscle and macrophages to form foam cells. Hydrogen, the lightest and smallest molecular gas in the atmosphere, is considered a novel antioxidant that reduces oxidative stress. Accumulating evidence from various biomedical fields in clinical studies and experimental models of many diseases suggests that hydrogen inhalation or drinking hydrogen-containing solutions can be used as a therapeutic strategy. Due to the special physical properties of hydrogen gas that is easy to diffuse, hydrogen molecules can penetrate cell membranes to reach organelles and cell nuclei. Hydrogen's moderate reducing properties make it effective in reducing cytotoxicity, protecting nuclear DNA and mitochondria, and reducing the risk of lifestyle-related diseases and cancer. In addition, hydrogen intake can reduce oxidative stress, improve cellular function, and reduce chronic inflammation, which are associated with the pathology and etiology of hyperlipidemia and other related diseases. Molecular hydrogen can regulate important metabolic functions such as signal transduction, protein phosphorylation, miRNA expression, and autophagy. Studies have shown that intake of hydrogen water in APOE knockout mice can reduce serum total cholesterol and low-density lipoprotein levels and prevent the progression of atherosclerosis. A study by Song et al. in 2013 included 20 subjects who drank 0.9 to 1 L of hydrogen-rich water per day for 10 weeks, and the subjects' LDL-C levels decreased significantly before and after treatment. Another study showed that subjects with underlying lipid metabolism abnormalities were treated with high-concentration hydrogen water (5.5mmol/d) for up to 24 weeks, and serum total cholesterol and low-density lipoprotein levels were significantly reduced. Protein function and redox status (eg, increased serum superoxide dismutase and decreased malondialdehyde) were improved, markers of inflammation (eg, serum tumor necrosis factor-alpha) decreased and fasting blood glucose decreased. At present, the research on the treatment of hyperlipidemia with hydrogen water is very limited. The portable hydrogen water hydrogen machine used in this study has passed the registration test of the Guangdong Provincial Medical Device Quality Supervision and Inspection Institute. In order to evaluate the use of the portable hydrogen water hydrogen machine for hyperlipidemia The efficacy and safety of adjuvant therapy in patients, this clinical trial is specially carried out.
To evaluate the efficacy and safety of dalpiciclib in patients with HR-positive/HER2-positive advanced breast cancer.
Evaluation of the efficacy and safety of adding rituximab after failure of target immunotherapy in the Posterior treatment of advanced hepatocellular carcinoma
The goal of this clinical trial is to learn about efficacy of Everolimus in combination with PD-1 in patients with locally advanced and advanced colorectal cancer that cannot be R0 resected. The main question is to explore the survival time, safety and tolerability of the treatment. At the same time, the correlation between biomarkers (including PD-L1 expression, tumor mutation load, lymphocyte subpopulation, cytokines, TCR, intestinal microbes, and others) and the efficacy and drug resistance mechanism will be analyzed, so as to provide reference for the subsequent guidance of the screening of benefit groups.
The goal of this clinical trial is to learn about a novel application of lidocaine injection in male patients who needs rigid cycstoscopy test. The main question it aims to answer is:Does New Application of Lidocaine Liquid Provide Pain Relief for Patients During Cystoscopy? Before the cycstoscopy,Participants will be randomly divided into three different anesthesia mode groups,namely are Group A (intraurethral lidocaine gel alone), Group B (intraurethral lidocaine gel + lidocaine 2% injection), and Group C (intraurethral lidocaine gel + liquid paraffinl).Patients only need to prepare and cooperate according to routine surgical operations，which is group B or group C.
The NCCN guidelines recommend induction chemotherapy followed by concurrent chemoradiotherapy as the standard treatment for locoregionally advanced nasopharyngeal carcinoma (NPC). However, meta-analyses have shown significant survival differences between different induction chemotherapy regimens. How to choose an induction chemotherapy regimen and treatment course that ensures definitive therapeutic effects and low incidence of toxic side effects remains a hot spot in clinical research. Polymeric micellar paclitaxel are an innovative form of paclitaxel drugs, with high penetration and long retention effects, which can enter the vascularly disordered tumor microenvironment through passive targeting and form higher concentrations in tumor tissue. It remains to be investigated whether the TPC (paclitaxel, cisplatin and capecitabine) regimen based on polymeric micellar paclitaxel compared to the current standard first-line induction chemotherapy GP (gemcitabine, cisplatin) regimen can further improve therapeutic effects in high-risk patients with locally advanced disease. There is still a lack of head-to-head studies for comparison. This study aims to compare, through a prospective, parallel-controlled, randomized, open-label, multicenter phase II clinical trial, the TPC induction chemotherapy vs. the GP induction chemotherapy combined with concurrent chemoradiotherapy for the treatment of high-risk locoregionally advanced NPC (T4 or N2-3) in terms of 2-year progression-free survival, overall survival, overall response rate, toxic side effects, etc.
This study explored the feasibility of dual-energy CT in head and lung tumors. Dual-energy CT can achieve quantitative CT imaging based on traditional imaging by dual-energy spectral imaging, and enhance the clarity of head and lung tumors. In this study, we will prospectively explore the image accuracy and delineation accuracy of dual energy CT in radiotherapy to verify whether dual energy CT performs better with conventional CT.
The study is to evaluate the safety, tolerability, and PK characteristics following single administration of HS-10509 in healthy adults, and multiple administrations of HS-10509 in patients with schizophrenia. Participants will have HS-10509 tablets or placebo once in the single ascending dose (SAD) part or once daily for 28 days in the multiple ascending dose (MAD) part.
This is a retrospective study, including 79 patients with duodenal papillary adenoma, who treated with Endoscopic Papillectomy (EP) at Beijing friendship hospital. The cohort included patients who underwent EP with or without Pancreatic Duct (PD) and Common Bile Duct (CBD) stent placement. The investigators assessed the outcomes of EP and the impact of stent placement on complications and recurrence rates.
Background： This study aimed to evaluate the effectiveness and safety of Finerenone in patients with chronic kidney disease (CKD) without diabetes mellitus(DM), however, evidence based on both clinical trails and real-world data are limited. Methods: Patients with CKD without DM were enrolled in this study from December 2022 to December 2024. In conjunction with the established treatment regimen for chronic kidney disease (CKD), study participants were additionally administered Finerenone. To evaluate the therapeutic impact and safety profile of the intervention, three primary biomarkers were monitored: 24-hour urinary protein (UTP), estimated glomerular filtration rate (eGFR), and serum potassium (sK+). These parameters were closely measured on a monthly basis, starting from the point of enrollment and continuing for a duration of twelve months or possibly longer.
