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.
The purpose of this study is to evaluate the effectiveness and safety of the suture-mediated closure system produced by Suzhou Hengrui Hongyuan Medical Technology Co., Ltd. following endovascular peripheral arterial procedures.
This study exploring the expression characteristics of different cells of peripheral blood after exposure to two kinds of hemodialysis filter membrane materials will help to elucidate the key mechanisms of hemodialysis filter coagulation occurrence, which is an important guideline for reducing the occurrence of adverse events in hemodialysis.
A multicenter, randomized, blind, controlled trial design was used to select 240 tuberculosis (TB) patients, 120 non-tuberculous community population with other lung diseases, and 420 healthy community population without other lung diseases who met the inclusion criteria of this study. Blood supply specific gamma-interferon (T-SPOT) detection was performed first. Then, EC and Purified Protein derivation of tuberculin (TB-PPD) skin tests were performed on both arms, and the recorded results were observed. The first 24 cases of TB patients, the first 12 cases of non-tuberculous community population with other lung diseases, and the first 42 cases of healthy community population without other lung diseases were included in the trial subgroup. Physical examination, blood routine, urine routine, liver and kidney function, and electrocardiogram tests were required before and 7 days after skin test after study number assignment.
The intravenous injection of lidocaine during the perioperative period has been widely used in various types of surgeries. Its clinical effect includes reducing stress response during anesthesia, decreasing pain and opioid consumption, lowering the incidence of postoperative nausea, vomiting, cognitive dysfunction, and reducing the injection pain of propofol. However, despite the positive impact of lidocaine on surgical patients, its mechanism of action remains unclear. Serum N/OFQ is a neurotransmitter that plays an important role in regulating pain and emotion. Therefore, this study aims to explore the effects of perioperative intravenous injection of lidocaine on stress responses in surgical patients, as well as its mechanism of action, and whether Serum N/OFQ participates in this process.
The goal of this China extension study is to evaluate the efficacy and safety of pembrolizumab plus belzutifan plus lenvatinib or pembrolizumab/quavonlimab plus lenvatinib versus pembrolizumab plus lenvatinib as first-line treatment in Chinese participants with advanced clear cell renal cell carcinoma (ccRCC). The primary hypotheses are (1) pembrolizumab plus belzutifan plus lenvatinib is superior to pembrolizumab plus lenvatinib with respect to progression-free survival (PFS) and overall survival (OS), in advanced ccRCC participants; and (2) pembrolizumab/quavonlimab plus lenvatinib is superior to pembrolizumab plus lenvatinib with respect to PFS and OS, in advanced ccRCC participants.
The goal of this study is to examine the efficacy of acupuncture in the management of acute postoperative urinary retention. Clinical question: Is acupuncture efficacious for postoperative urinary retention after hemorrhoidectomy compared with sham acupuncture and neostigmine. Study design: The participants who undergo hemorrhoidectomy and report postoperative urinary retention will receive one session of acupuncture or sham acupuncture or one injection of 1-mg neostigmine. The primary outcome was the time to first urination after surgery.
A trial to evaluate the safety and efficacy of the Tubridge Plus flow-diverter stent for the treatment of intracranial wide-necked aneurysms.
Brief Summary: The study was conducted in two parts, the first of which was carried out using a cross-sectional design approach to explore the relationship between cognitive function and autonomic function, brain function, inflammation and oxidative stress, vascular function, fitness levels, cardiorespiratory endurance and lipid metabolism. The second part uses a repeated measures design approach in a randomised controlled design to explore the effects of different types of exercise on cognitive decline in postmenopausal hypertensive women and their mechanisms of action.
Transcervical resection of myoma(TCRM) has a good therapeutic effect while the probability of complete resection of type I and II fibroids is only 55% per procedure on average and a significant number of patients have fibroid remained.At present, there is no standardized treatment option for reducing the remaining submucous fibroids volume and preventing its recurrence after TCRM.The present prospective,multicentre,randomised controlled clinical trial will enrol women after TCRM and treat them with mifepristone(10mg)or GnRHa(3.60mg)for 3 to 6 months,investigating the effective and cost-effective treatment options after fibroids with TCRM，thus to provide evidence and effectual regiments for reducing remaining fibroids volume and preventing its recurrence.
The objective of this study is to evaluate the medium- to long-term safety of the Carbomedics OptiForm Mitral Heart Valve after the implantation for mitral valve disease in the Chinese population. The study is designed as a post-market, retrospective, single arm and multicentric data collection
