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.
Our aim was to describe the development and usability of a mobile device-based game therapy software for ADHD.
The aim of this study is to evaluate the safety, tolerability, and pharmacokinetic characteristics of TNP-2092 Capsules in liver cirrhosis patients with hyperammonemia; and to preliminarily observe the effects of the study drug on blood ammonia and hepatic encephalopathy related clinical symptoms and signs, neuropsychological indicators, and quality of life in liver cirrhosis patients with hyperammonemia.
Here, this study aimed to conduct magnetic resonance neurography (MRN) of the thoracic DRGs in a cohort of healthy individuals. The acquired images will be thoroughly analyzed utilizing 3D-slicer software. We expect to furnish crucial baseline anatomical data of thoracic DRGs in healthy subjects, provide an anatomical basis for clinical investigation and therapeutic interventions.
To evaluate the safety and immunogenicity of lyophilized human rabies vaccine (Vero cell) developed by Hualan Biological in healthy people aged 9 to 65 years with two different immunization schedules.
Endoscopic dacryocystorhinostomy (En-DCR) has the advantages of less surgical trauma, shorter time, less postoperative bleeding, faster recovery, and no skin scars. However, the success rate of En-DCR surgery still varies greatly between 58% and 94% , and the main reason for the failure of the surgery is the membranous closure of the anastomosis. The application of new packing materials in dacryocystorhinostomy provides some new ways to improve the success rate of En-DCR. Hydroxybutyl chitosan (HBCS), with its non-toxicity, biocompatibility, biodegradability, antibacterial, moisturizing properties, water solubility and temperature sensitivity, is widely used in biomedicine to prevent postoperative adhesions. 5-Fluorouracil (5-FU) is an antimetabolite drug that is effective in the treatment of keloids. The application of 5-FU in glaucoma filtration surgery has demonstrated its good safety and efficacy. Studies have shown that antimetabolites as adjuvant therapy for DCR have a positive impact on improving the success rate of surgery In this study, thermosensitive hydroxybutyl chitosan will be applied to the anastomosis site of the nasal mucosal flap and the lacrimal mucosal flap, or 0.3ml of 5-fluorouracil solution (25mg/ml) was injected into the nasal mucosa around the anastomosis at the same time. The investigators would like to observe the different situations of clinical symptoms, lacrimal duct flushing, endoscopy, and bacterial flora changes in patients with chronic dacryocystitis, to compare them with the previous intraoperative packing of gelatin sponge wrapped with thrombin and Tobramycin Dexamethasone. Furthermore, the investigators intend to evaluate the safety and efficacy of HBCS and 5-FU adjuvant internal En-DCR in the treatment of chronic dacryocystitis, and provide new ideas for the adjuvant therapy of En-DCR.
The goal of this observational study is to conducted a comprehensive analysis of the factors contributing to redo- Pull-through surgery for constipation recurrence in Children who are suffering from Hirschsprun' s disease (HSCR) and its allied disorders (ADHD) . The main question[s] it aims to answer are: 1. Our study focused on the treatment and prognosis of these conditions, drawing upon 16 years of patient data and clinical experiences" 2. What are the key risk factors affecting the prognosis of recurrent constipation patients undergoing repeat PT?
To validate and investigate the efficacy of comprehensive functional assessments for the diagnostic and prognostic value in NOCAD.
When the liquid flow increases, the luminal caliber's stretching amplitude decreases, leading to a higher hydraulic pressure according to Poiseuille's law. In this study, investigators measured the caliber change of the popliteal vein under a rated pressure gradient and evaluated the relationship between popliteal vein compliance and venous clinical severity score (VCSS).
Fiber colonoscopy, as a terminal examination method for lower gastrointestinal diseases, often brings varying degrees of pain, discomfort, tension, and anxiety to patients. Therefore, currently in clinical practice, intravenous anesthesia is often chosen to reduce discomfort. At present, intravenous propofol and fentanyl are most widely used in clinical practice, but intravenous general anesthesia can lead to hemodynamic fluctuations and an increase in anesthesia related complications such as prolonged hospital stay after surgery. Propofol and remifentanil have the characteristics of fast onset, short duration of action, and rapid awakening. The purpose of this study is to observe the efficacy and adverse reactions of remifentanil combined with low-dose propofol in patient-controlled analgesia and sedation during colonoscopy, in order to explore the safety and effectiveness of this method.
This prospective, multicenter, single-group, target-value clinical trial was designed to evaluate the efficacy and safety of an Adaptive Optics ScanningLaser Ophthalmoscope(AOSLO) for ophthalmic examination.
