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 goal of this clinical trial is to compare the effect of high chlorine solution such as normal saline and non-high chlorine solution such as sodium lactate ringer's solution on renal function in patients with heat stroke. The main question it aims to answer is whether limiting the amount of normal saline infusion during emergency department can lower the incidence of acute kidney injury and mortality in patients with heat stroke. Participants will receive a free normal saline infusion during the emergency department according to the study design, or a restricted normal saline infusion while using sodium lactate Ringer's instead. Researchers will compare the normal saline infusion group and sodium lactate Ringer's group to see if limiting the amount of normal saline infusion during emergency department can lower the incidence of acute kidney injury and mortality in patients with heat stroke.
The goal of this observational study is to explore the optimal target body temperature in first 24 hours and the relationship between body temperature and adverse outcomes of heat stroke. The main questions it aims to answer are: - the optimal target body temperature at 0.5 h, 2 h, and the lowest body temperature of heat stroke. - the best body temperature at the cutting point of stop cooling. - The relationship between the volume and speed of ice saline infusion and the cooling effect.
Postmenopausal women with hormone receptor-positive breast cancer are now prescribed aromatase inhibitors with 5 years or longer durations of therapy as recommended by clinical guidelines, which contributes to reducing breast cancer recurrence. However, aromatase inhibitors treatment is associated with a high incidence of musculoskeletal symptoms (MSS), often described as symmetrical pain, soreness in the joints, musculoskeletal pain, and joint stiffness, which even leads to bone loss, osteoporosis, and fractures. MSS reduces patients' quality of life and compliance with aromatase inhibitors therapy in up to one-half of women undergoing adjuvant aromatase inhibitors therapy, potentially compromising breast cancer outcomes. Therefore, this study aimed to monitor the musculoskeletal health of breast cancer patients during endocrine therapy to provide references for clinical practice.
The aim of the study is to evaluate the efficacy and safety of Beijing protocol in malignant haematologic disease patients receiving more than 5/10 HLA-mismatched allo-HSCT.
This trial is a randomized (1:1) phase III open label study of frontline mini-MTX plus methylprednisolone 2mg/kg/day compared to methylprednisolone 2mg/kg in allogeneic stem cell transplant recipients with grade 2-4 aGVHD.
A Randomized Study of RJ4287 Drug to Evaluate the Safety, Tolerability, Pharmacokinetics and Food-effect of Single and Multiple Doses in Healthy Volunteers
The goal of this single-center, prospective, double-blind randomized controlled clinical trial is to explore preventive interventions for chronic postoperative pain (CPSP) in patients undergoing minimally invasive cardiac surgery. The main questions it aims to answer is: the incidence of CPSP is high and severe, and there is no safe and effective method for prevention and treatment. The participants in the dexamethasone palmitate (DXP) group will receive a single paravertebral space infusion of 21 ml of the first dose of analgesia, consisting of 0.5 percentage ropivacaine 20 ml and dexamethasone palmitate 1ml. The participants in dexamethasone sodium phosphate (DXM) group will receive a single infusion of a paravertebral space first dose of 21 ml of analgesic containing 0.5 percentage ropivacaine 20 ml and dexamethasone sodium phosphate 1ml. Then both groups use a continuous paravertebral nerve block pump for postoperative analgesia. The liquid of the pump is 250 ml 0.2 percentage ropivacaine. The background of the pump is set to 5 ml/h and PCA is set to 5 ml at an interval of 30 min.
Establish a clinical cohort of acute ischemic stroke patients and find the determinant of the prognosis.
Endovascular thrombectomy (EVT) is a highly effective therapy for acute ischemic stroke with large vessel occlusion (LVO). EVT was proven efficacious in selected patients with symptoms onset or last-known-well time of up to 24 hours. With a number-needed-to-treat (NNT) of 2.3-2.8 to achieve functional independence, EVT had become the current state-of-the-art treatment for ischemic stroke with LVO. Nevertheless, more than half of LVO strokes suffered from functional dependence or death despite EVT. Futile EVTs were contributed by peri-procedural malignant brain edema (MBE) and symptomatic intracranial hemorrhage (sICH). Studies suggested that 26.9% of EVTs were complicated by MBE, whereas sICH was present in 6-9% of LVO patients who received EVT. The fundamental pathophysiology of MBE and sICH is blood-brain-barrier (BBB) disruption secondary to ischemia, mechanical and reperfusion injury. These pathological processes can result in increased tissue permeability, excess production of oxygen free radicals and inflammatory response that eventually lead to hemorrhage and edema. Poor collateral circulation, proximal LVOs, intravenous thrombolysis, blood pressure and glucose fluctuation had all been implicated to in MBE and sICH. However, these risk factors were either unmodifiable or not shown to improve EVT outcomes. The preliminary results of a recent randomized trial even suggested harmful effects of intensive blood pressure following EVT. With indications of EVT are expanding to patients with prolonged ischemia and large ischemic cores, enhancing BBB and neuronal tolerance to ischemia and reperfusion therapies may hugely impact on EVT outcomes. Recent animal models have shown that glucagon-like peptide peptide-1 receptor agonists (GLP-1RA) significantly reduced infarct volume and neurological deficits following temporary or permanent middle cerebral artery occlusion. These effects were likely due to the anti-oxidant, anti-inflammatory and anti-apoptotic properties of GLP-1RA that protected BBB integrity and ischemic neurons during induced LVO and/or reperfusion. Investigator hypothesizes that compared to standard reperfusion strategies, administration of GLP-1RA in LVO patients who receive EVT may prevent the development of MBE and sICH, and improve neurological outcomes. In this randomized, open-label pilot study, investigator aims to determine the effect of semaglutide, a GLP-1RA, on the radiological and clinical outcomes in LVO patients undergoing EVT.
The purpose of this study is to characterize the safety of QLS32015 injection and to determine the recommended Phase 2 dose (RP2D) and to further evaluate the efficacy and safety of QLS32015 injection in participants with relapsed or refractory multiple myeloma at the recommended Phase 2 dose.
