Clinical trials

This was a multicenter, randomized, open label, non inferiority clinical study. It consisted of a 24-week treatment period (0-24 weeks) and a 24-week extension period (25-48 weeks). About 160 patients which had received Recombinant human erythropoietin (rHuEPO) or Hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI) treatment were randomized in a 1:1 ratio to receive Pegmolesatide with different administration regimens.

In radiofrequency (RF) ablation of persistent atrial fibrillation (PeAF), the additional linear ablation beyond pulmonary vein isolation (PVI) does not yield an reduce atrial arrhythmias recurrences.The goal of this clinical trial is to evaluate the efficiency of pulsed filed (PF) energy-based bi-atrial modified Maze ablation vs PF energy-based PVI of PeAF. The main questions it aims to answer are: Does PF energy effectively perform linear ablation in the left atrium? Does PFA-based bi-atrial modified Maze ablation significantly improve the success rate of PeAF ablation compared with PFA-based PVI? Patients with PeAF who meet the criteria and undergo catheter ablation will be randomly assigned to the study group (PF-based bi-atrial modified Maze ablation group) and control group (PF-based PVI only) in a 1:1 ratio. All patients will received a 7-d Holter at 3-,6-,9-,12-month after the ablation. The primary endpoint is the freedom from documented atrial arrhythmia (AF/AFL/AT lasting for over 30 seconds) recurrence monitored by ECG, 7-day ambulatory ECG, or equivalent cardiac monitoring from 4th to 12th month after the procedure without taking I/III AADs.

This study explores the impact of long-term benzodiazepine (BZDs) use on cognitive function and associated neuroimaging markers. While BZDs are established treatments for conditions like anxiety and insomnia, recent warnings highlight risks, including neurocognitive effects. Neuroimaging studies indicate potential neuroprotective effects of BZDs. Functional near-infrared spectroscopy (fNIRS) measures cerebral cortex function during cognitive tasks. Combining fNIRS with mood and cognitive scales, this study assesses cortical activation. 2-deoxy-2-fluoro-D-glucose-positron emission tomography (FDG-PET) evaluates brain metabolism. DPA-714 PET assesses neuroinflammation. The primary objective is to compare brain functional activation, metabolism, and neuroinflammatory levels between long-term BZD users and non-users. This comprehensive approach aims to provide insights into BZD effects on cognition and associated brain markers.

The current practice of anesthesia for atrial fibrillation catheter ablation （CA） procedure is inconsistent, including general anesthesia, deep sedation, and conscious sedation.Due to the nature of deep sedation, it has been continuously gaining its position as one of the crucial components in standard practices of atrial fibrillation ablation during the last decade. Currently, a considerable number of procedures have been done using conscious sedation. Previous studies explored the benefits obtained from the employment of deep sedation in AF ablation procedures, mainly focused on pain reduction and intra-procedural safety. However, the benefits on long-term rhythmic outcomes, peri-procedural safety as well as benefits on procedural parameters and peri-procedural experiences from patients/ablators/lab staff have yet not to be thoroughly studied. We plan to conduct a prospective, multicenter, randomized, controlled trial to evaluate the benefits of deep sedation in catheter ablation of paroxysmal and persistent AF in multiple prospective, i.e., quantified intraprocedural patients / physicians / lab staffs / mapper clinical specialist experiences, and the procedure safety.

Depression, a common psychological disorder, is characterized by persistent low mood, loss of interest, and anhedonia, leading to significant dysfunctions and a high suicide risk. Its pathogenesis remains challenging, with recent focus on neuroinflammation-a chronic immune response in the central nervous system-as a potential contributor. PET imaging, using tracers like 18F-FDG and \[18F\]DPA-714, can visualize metabolic and neuroinflammatory changes. Combining these two tracers can explore the correlation between neuroinflammation and glucose metabolism in depression, further elucidating its possible mechanisms. We hypothesize that microglial activation in depression, especially in major gray matter regions of interest (prefrontal cortex, anterior cingulate cortex, and insula) and 12 additional regions and subregions, will show higher TSPO levels and increased glucose metabolism compared to the control group.

This is a multicentre prospective, randomized, double-blind and imitation, positive-drug parallel controlled clinical trail. The objective of this study is to evaluate the efficacy and safety of Huaiqihuang Granule in patients with CKD stage 3 primary glomerulonephritis.
