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.
Hyperthyroidism is an endocrine disease with a high incidence rate, and some patients are difficult to effectively control the condition after long-term drug treatment, and the disease recurs, forming refractory hyperthyroidism. The search for a new safe, effective and minimally invasive treatment has become a research hotspot. Ultrasound-guided radiofrequency ablation is a hot spot in clinical research due to its advantages of low trauma, high safety, precise inactivation of lesions, and multiple ablation. However, there is no unified standard for the number and scope of ablation in the treatment of refractory hyperthyroidism by radiofrequency ablation, and there is a lack of data on the effectiveness and safety of the treatment with large samples and long-term effects. Therefore, how to establish a standardized treatment strategy and appropriate plan for ablation of refractory hyperthyroidism based on clinical practice is an urgent problem to be solved. The purpose of this study was to prospectively include refractory hyperthyroidism for ultrasound-guided radiofrequency ablation, and to evaluate the efficacy and safety of hyperthyroidism ablation by comparing the changes in symptoms and signs, serology, and imaging of patients before and after ablation. The relevant factors affecting the efficacy of ablation were analyzed and the most appropriate ablation scope was determined. Radiofrequency ablation was retrospectively compared with traditional surgery and 131I treatment, and the near- and medium-term treatment effects, incidence of adverse reactions and complications, as well as the economic benefits and sociopsychological differences of the three treatment methods were compared. The expected outcome of this study is to establish a research cohort of hyperthyroidism ablation based on a large sample population, and to establish the most appropriate and effective regimen for radiofrequency ablation of refractory hyperthyroidism compared with traditional surgery and 131I treatment with safety and near- and medium-term efficacy. The Department of Ultrasound Medicine of China-Japan Friendship Hospital has accumulated rich experience in the ablation treatment of benign and malignant thyroid nodules and hyperthyroidism, and has completed more than 200 cases of thyroid ablation in the past two years. Under the leadership of Professor Zhang Bo, the research team of this project has conducted a number of clinical studies on the ultrasound diagnosis and treatment of thyroid diseases, presided over and participated in more than 20 national, provincial and university-level scientific research courses, and the first author or corresponding author wrote more than 70 articles in related fields, which laid a solid research foundation for the conduct of this study.
To evaluate the efficacy and safety of rezvilutamide in combination with androgen deprivation therapy(ADT) and standard salvage radiation therapy(SRT) or SRT combination with ADT in prostate cancer patients with biochemical recurrence of prostate-specific antigen(PSA) persistence after radical prostatectomy(RP).
A multicenter real-world study was conducted to gather clinicopathological data from patients with HER2-positive metastatic breast cancer who were treated with inetetamab between 2022 and 2023. The study aimed to estimate the progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and adverse events (AEs) associated with inetetamab therapy.
A Study to Evaluate the Safety and Efficacy of the Bausch + Lomb Myopia Control Lens for the Correction of Myopic Ametropia and Slowing the Progression of Myopia in Children
This study aims to investigate the effects of Bifidobacterium breve BBr60 on key health indicators in overweight and obese adults. Specifically, it will assess the probiotic's impact on body composition metrics such as BMI, body fat percentage, WHR, and BMR. The inclusion criteria for participants are a BMI of ≥28 kg/m^2, targeting individuals who stand to benefit significantly from metabolic and body composition improvements.
The purpose of the intraoperative use of opioids is to reduce the amount of sedative medication and to ensure effective analgesia. But pain is an unpleasant sensory and emotional experience (a cognitive perception) that cannot occur with sufficient depth of anesthesia (even without opioids). So a more reasonable explanation for analgesia should be anti-nociception and the resulting inhibition of the response to surgical stress. Since multiple mediators are involved in nociceptive pathways, antinociception can also be acquired through multiple mechanisms. However, there is no single ideal harm drug to replace opioids, which often requires two or more drugs to meet clinical needs. While regional block attenuates the stress response to surgery and sympathetic activation because of afferents to block nociceptive stimuli, and has an important role in the implementation of OFA. Combined with the clinical characteristics of the LSG, investigators developed the transverse abdominis fascia block (transversus abdominis plane TAP) in combination with esketamine (esketamine), dexmedetomidine (dexmedetomidine, DEX) of opioid-free anesthesia (opioid free anesthesia, OFA) and the analgesic regimen (TEDOFA), Reduce patient pain scores, nausea and vomiting after LSG based on perfect analgesia and adequate anti-sympathetic response, As well as the other complications, Promote the accelerated postoperative recovery of patients undergoing LSG, And reduce the incidence and severity of postoperative chronic pain.
The goal of this prospective multicenter open label study is to evaluate the efficacy and safety of intravitreal injection Conbercept (IVC) for the treatment of diabetic macular edema (DME) combined with severe nonproliferative diabetes retinopathy (sNPDR). The main questions it aims to answer are: - mean changes in best corrected visual acuity (BCVA) and central macular thickness (CMT) in comparison with baseline at 12 months after initial treatment - proportion of eyes with visual gain ≥15 letters in Early Treatment Diabetic Retinopathy Study (ETDRS) chart and ≥2-step improvement in Diabetic Retinopathy Severity Scale (DRSS) score after 12 months of the treatment - proportion of eyes actually underwent PRP treatment after 3 and 12 months of the treatment - mean changes in BCVA and CMT from baseline to monthly follow-up time point - complications and adverse effects
This is a randomized, blind, positive-controlled study to explore the skin test dosage of recombinant mycobacterium tuberculosis fusion protein ( EEC) in the population aged 18 to 65 years old , and to further evaluate the safety and preliminary efficacy of EEC in the population aged 3 to 75 years old. In the first stage,180 healthy subjects, 140 tuberculosis（TB）subjects and 40 non-TB subjects with lung diseases aged 18 to 65 years old are divided into different groups through a randomized, blind methods. Every group carry out a low-dose (2.5μg/ml) or high-dose (5μg/ml) study, with 180 subjects in each dose group .Every subject injects intradermally EEC and EC randomly in both arms of the same person. Evaluate the consistency of assay results of EEC, EC and Interferon-Gamma Release Assay（IGRA）.Evaluate the sensitivity, specificity and consistency of assay results of EEC, EC and IGRA in healthy people, TB patients and non-TB patients with lung diseases, and determine the optimal dose of EEC for clinical auxiliary diagnosis of tuberculosis. In the second stage, 60 healthy subjects and TB subjects aged 3-17 years and 66-75 years old are divided into different groups through a randomized, open, single-arm method with the target dose. Evaluate the safety, tolerance and preliminary efficacy of target dose of EEC in healthy people and TB patients aged 3 to 17 years old and 66 to 75 years old.
