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.
This observational study will involve analysis of data collected by the National Rare Disease Registry or medical records .The study will describe outcomes only in PAH(Pulmonary arterial hypertension) patients treated with sildenafil; there will be no comparison with another treatment group. Approximately 100 adults with PAH will be recruited in China hospitals This NIS(non-interventional study) data will be recorded by a physician in the medical records, during the patients' clinical visits, and in the electronic Case Report Forms (CRF).
Metabolic associated fatty liver disease(MEFLD) is a major chronic liver disease that can lead to various adverse events, such as liver cancer, cardiovascular disease, and chronic kidney disease. The present community-based cohort study enrolls subjects who take health physical examinations at the sub-center outpatient department, Beijing Friendship Hospital. Investigators collect their baseline information, including demographic data, clinical history, physical examination, laboratory results, imageological examination, and so on. Follow-up surveys are conducted annually and the information collected is the same as the baseline. The outcome information, including cardiovascular disease, malignancy, liver cirrhosis, liver decompensation, liver transplantation, and all-cause mortality, are obtained by linking to the hospital discharge database and death registration system of Beijing. The primary aim of the study is to build a risk-stratified evaluation system for MAFLD through the cohort.
This study aimed to investigate the efficacy and safety of venetoclax combined with dexamethasone and etoposide as a salvage therapy for hemophagocytic lymphohistiocytosis.
To evaluate the feasibility and safety of gasless transaxillary posterior endoscopic thyroidectomy (Resection of thyroid lobe and isthmus, lymph node dissection in the central area of the affected side) and open radical thyroidectomy (Resection of thyroid lobe and isthmus, lymph node dissection in the central area of the affected side) as the current standard surgical treatment mode in terms of feasibility and safety of radical thyroidectomy.
The purpose of this studay is to compare the efficacy of different hypoglycemic regimens versus twice-daily premixed insulin in type 2 diabetes mellitus (T2DM) patients after short-term ntensive Insulin Therapy by using continuous glucose monitoring.
This is a prospective, randomized, open-label, non-inferiority, multiple-center trial. Outpatients who are scheduled to undergo colonoscopy and found eligible polyps will be randomized to receive either cold snare endoscopic mucosal resection (CS-EMR) or hot snare endoscopic mucosal resection (HS-EMR). This study aims to compare the efficacy and safety of CS-EMR or HS-EMR for the resection of non-pedunculated colorectal polyps sized 10-19mm.
This study retrospectively analyzed cases of remote robot-assisted spine surgery performed jointly by the Beijing Jishuitan Hospital Spinal Surgery and partner hospitals, with cases of local orthopedic robot-assisted spine surgeries performed by Beijing Jishuitan Hospital between April 2021 and December 2021.
This is a cross-sectional and longitudinal study to investigate the relationship and central mechanism between type 2 diabetes and cognitive impairment based on the simultaneous EEG-fMRI approach and peripheral neuropathology biomarkers assay.
This study intends to explore the correlation between cervical microbiome, gut microbiome, transcriptome and pregnancy outcomes of frozen embryo transfer patients through a multicenter prospective observational study, and to explore the predictive value of microbiome on pregnancy outcome.
The effect of brain-heart interaction remains unclear. The study aims to investigate the biological interconnection between brain neural activity and coronary plaque morphological and inflammatory features, as well as their connection with clinical outcomes.
