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.
Patients who meet the enrollment criteria will be randomized 1:1 to the lidocaine group or placebo group.
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.
This is a monocenter, single-arm, open-label study to evaluate the efficacy and safety of Lenvatinib combined with Tislelizumab and TACE applied as neoadjuvant regimen for the patients of CNLC stage IB and IIA hepatocellular carcinoma with high risk of recurrence Primary outcome: Major pathological response (MPR) Secondary outcomes: pathological complete response (pCR), R0 resection rate, objective response rate (ORR), disease control rate (DCR), treatment-related adverse events (TRAE)
Explore the shared or separated neural mechanisms of social exclusion and social segregation and compare differential effects of AVP and OXT on these social interaction function.
This was a multicenter observational study of Orelabrutinib in the treatment of CLL/SLL. Patients were treated with Orelabrutinib for 12 cycles. The primary end points were grade 3 hypertension and incidence of atrial fibrillation, and the secondary end points were improvement in abnormal markers, ORR,CR,PFS, and OS.
The goal of this clinical trial is to determine the clinical efficacy and toxic effects of sodium valproate, sirolimus and calcitriol in the treatment of severe haemophilia in participants with severe haemophilia . The main questions it aims to answer are the possibility of adding a combination regimen to primary treatment for severe haemophilia . Patients will receive oral sodium valproate extended-release tablets 0.5g/day, sirolimus tablets 1mg/day and osteopontin capsules 0.25μg/day.
