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.
Macular hiatus (MH) refers to a tissue defect in the photoreceptor cell layer of the inner boundary membrane of the optic disc in the macular region. Among them, idiopathic macular hiatus (IMH) is more common in people over 60 years old and is a common eye disease. With the aging of society, the number of patients increases, and it severely damages the patients' vision and life quality. Previously, the conventional surgical approach for treating MH was vitrectomy combined with inner limiting membrane (ILM) peeling. Although the closure rate of MH is high, many damages to the morphology and function of the ILM peeled area have been found. Our team firstly report a novel technique of peeled ILM reposition. Compared to traditional ILM peeling, the novel technique peeled ILM reposition maintains the integrity of internal retina by "pull" back the ILM flap. The previous pilot clinical study suggests that the novel technique peeled ILM reposition surgical intervention can achieve better morphology and functional prognosis. However, there is currently a lack of larger sample size prospective randomized controlled studies to further clarify the clinical efficacy of this new surgical technique in treating IMH. This study aims to conduct a single center, prospective, and randomized controlled study, combined with previous work, to analyze the efficacy of this novel technique peeled ILM peeling in the treatment of IMH. We hypothesize that this novel technique can achieved better morphological and functional prognosis compared to traditional ILM peeling.
This study analyzed the efficacy and safety results of HSK21542 injection for the prevention of postoperative nausea and vomiting in a multicentre, randomized, double-blind, placebo-controlled dose-exploration study, as well as the real-world clinical routine use of troisisone and other (not limited to other setron drugs) for the prevention of postoperative nausea and vomiting and related adverse reaction treatment data. It was transformed into an effect indicator, and the possible costs involved in the study were analyzed, reasonable price parameters of HSK21542 injection were set, and the economic value of HSK21542 was explored.
This trial is a phase II clinical trial of the safety and efficacy of PD-1 antibody (Toripalimab) in combination with paclitaxel (albumin-bound type) and gemcitabine and PULSAR radiotherapy in patients with locally advanced unresectable pancreatic cancer and patients with only local recurrence after pancreatic cancer surgery, to observe the safety and efficacy of PD-1 antibody (Toripalimab) in combination with paclitaxel (albumin-bound type) and gemcitabine and PULSAR in the treatment of patients with locally advanced unresectable pancreatic cancer.
The purpose of this study is to predict the CT visual score of emphysema with EIT-based parameters, in order to provide a non-invasive and convenient method for the evaluation of lung structure and physiological and pathological progression of COPD.
This was a multicenter, prospective, parallel-grouping, randomized controlled clinical study comparing low FiO2 (40%) and high FiO2 (80%) levels in older patients undergoing laparoscopic gastrointestinal surgery.
This study adopts a multicenter, open, prospective, and self controlled study design, in which each participant serves as their own control before and after receiving amino acid peritoneal dialysis solution treatment to compare changes in their nutritional status. Each subject received treatment with 1 bag of amino acid peritoneal dialysis per day and 2-4 bags of glucose peritoneal dialysis solution per day for 6 months (the amount of glucose peritoneal dialysis solution used was determined based on the treatment plan selected by the patient during the screening period when they entered the study).Before treatment and during the 3rd and 6th months of treatment, subjects were evaluated for various efficacy and safety indicators, and any adverse or serious adverse events were recorded.
The goal of this clinical trial is to learn if combined local injection of platelet rich plasma (PRP) gel adds clinical efficacy to isolated arthroscopic microfracture in treatment of osteochondral lesion of the talus (OLT). The interface integration of the injured area will also be assessed via radiographic follow-up. The main questions it aims to answer are: - Does arthroscopic microfracture combined with PRP gel injection improve ankle function of participants based on American Orthopedic Foot and Ankle Society (AOFAS) Score? - Does arthroscopic microfracture combined with PRP gel injection improve interface integration of the injured cartilage on magnetic resonance imaging (MRI)? Researchers will compare arthroscopic microfracture with concomitant local injection of PRP gel to isolated microfracture to see if intraoperative PRP gel injection adds clinical efficacy to isolated arthroscopic microfracture in treatment of OLT. Participants will: - Undergo either isolated arthroscopic microfracture or microfracture with intraoperative injection of PRP gel - Receive clinical follow-up 3, 6, 12, and 24 months after surgery and answer scales of ankle function assessment - Take MRI preoperatively and 6, 12 and 24 months after surgery
This is a single center, prospective and observational study conducted in three stages to predict the NSCLC lymph node metastasis based on ctDNA/specific methylation molecular features combined with PET-CT imaging features and intervention study.
After menopause, there is a certain tendency towards depression, with the risk of developing depression being about 3 to 4 times higher than before menopause. Additionally, postmenopausal women experience varying degrees of cognitive decline, which are closely associated with hormonal changes. Therefore, we should pay more attention to the cognitive levels of postmenopausal depression patients. Increasing evidence suggests that changes in cognitive function during menopause may be related to the effects of estrogen on cognitive function, and estrogen therapy can effectively improve cognitive decline. Estrogen is not only associated with cognitive symptoms after menopause, but estrogen intervention is also an adjunctive treatment for postmenopausal depression symptoms. There is a close relationship between cognitive levels and depression, as depression itself is accompanied by cognitive decline, and early cognitive decline can also manifest depressive symptoms. Therefore, the cognitive levels of postmenopausal depression patients are also worthy of further attention.This study is an 8-week randomized controlled trial. The subjects are patients with postmenopausal depression accompanied by cognitive decline, all of whom have undergone natural menopause for at least one year; with HAMD-17 scores ≥17 points; and MOCA scores ≤26 points. This study aims to recruit patients with postmenopausal depression accompanied by cognitive decline from the outpatient or inpatient departments of Beijing Anding Hospital, Capital Medical University. Patients who meet the inclusion criteria will be randomly assigned to the combination group and the control group using a random number method. The combination group will receive estrogen combined with SSRIs, while the control group will only receive Selective serotonin reuptake inhibitors (SSRIs) intervention. Patients' cognitive function and depressive symptoms will be assessed using scales at baseline, 2 weeks, 4 weeks, and the end of 8 weeks of treatment, and safety evaluations will be conducted. The primary efficacy endpoint is the change in MoCA scores from baseline to the end of the study. Secondary efficacy endpoints include changes in HAMD-17, modified Kupperman Scale, ADL Scale, and hormone levels from baseline to the end of the study. The safety of the study drug will be evaluated through adverse event reporting, clinical laboratory tests, and physical examinations.
This is a prospective, open-labled, randomized controlled study to assess efficacy and safety of treatment with Sintilimab (PD-1 antibody) combined Peg-IFNα-2b in CHB patients on stable NAs treatment.
