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 patients with coronavirus infection usually have fever, respiratory symptoms, headache, toothache, muscle soreness, physical decline, and so on, while others are asymptomatic patients. It is urgent to find drugs to improve the long-term rehabilitation of symptomatic patients with coronavirus infection and decrease the duration of viral shedding in both symptomatic and asymptomatic patients. This study aims to investigate the efficacy and safety of Lianhua Qingwen capsules in patients with coronavirus infection. The duration of viral shedding and symptoms before discharge, as well as the negative conversion ratio and disappearance ratio of main symptoms after 7-day treatment, will be evaluated. 6-month follow-up will be performed to evaluate the effect of Lianhua Qingwen on all infection events and the long-term rehabilitation of the symptoms induced by coronavirus infection.
The patients with Omicron infection usually have fever, respiratory symptoms, tachycardia, headache, toothache, muscle soreness, physical decline, and so on, while others are asymptomatic patients. It is urgent to find drugs to improve the long-term rehabilitation of symptomatic patients with Omicron infection and decrease the duration of viral shedding in both symptomatic and asymptomatic patients. This study aims to investigate the efficacy and safety of Lianhua Qingke tablets in patients with Omicron infection. The duration of viral shedding and symptoms will be evaluated. 6-month follow-up will be performed to evaluate the effect of Lianhua Qingke on long-term rehabilitation of all symptoms induced by Omicron infection, as well as infection events.
Diabetic painful peripheral neuropathy (DPN) constitutes a serious threat to the outcomes of patients with diabetes. Yet, the treatments for targeting the underlying nerve damage and relieving pain are limited. The low-intensity focused ultrasound (LIFU) has been demonstrated to regulate neuronal activity without any concomitant tissue damage. Studies in animal models have shown that LIFU could protect nerve cells against inflammation and oxidative stress, as well as stimulate neurotrophic factor production. In humans, LIFU has been reported to be effective in relieving peripheral neurogenic pain caused by carpal tunnel syndrome and chemotherapy drugs. Thus, we aim to design a randomized controlled double-blind study by using LIFU. The primary endpoint is the patient's pain score (NRS), and the secondary endpoints include Neuropathy Symptom Score (NSS) and Neuropathy Deficit Score (NDS). Through this study, we anticipate establishing a new method for managing painful DPN.
This is a restrospective study to establish a deep learning model based on multi-parametric magnetic resonance imaging scans to predict Grade, histopathologic type and genotype of adult diffuse Glioma.
The aim of this study is to explore if STI technology, especially TMAD, plays an important role in evaluating left ventricular longitudinal systolic function and discriminating SICM in patients with sepsis. The investigators also intend to prove that TMAD may have predictive value in patients with sepsis, which is worthy of in-depth study to find strong evidence-based medical evidence for subsequent clinical practical applications.
The purpose of this study is to evaluate the efficacy and safety of nemtabrutinib compared to investigator's choice of fludarabine plus cyclophosphamide plus rituximab (FCR) or bendamustine plus rituximab (BR) in participants with previously untreated CLL/SLL without 17p deletion and/or tumor protein (TP) 53 mutation. The primary hypothesis is that nemtabrutinib is superior to FCR/BR with respect to progression-free survival (PFS).
The purpose of this study is to evaluate the effect of tozorakimab, as an add-on to SoC in patients with viral lung infection requiring supplemental oxygen, on the prevention of death or progression to IMV/ECMO.
A study to evaluate the effectiveness and safety of ExAblate transcranial MRgFUS Thalamotomy treatment of medication refractory tremor-related diseases subjects with low skull density ratio (SDR) value. Essential tremor (ET) and Parkinson disease (PD) are the most prevalent tremor disorders. ET, considered as a pure tremor disease, is characterized by upper limb intention or postural tremor, while PD is characterized by a variety of motor and non-motor symptoms, among them rest tremor. A number of studies have demonstrated that Magnetic resonance-guided focused ultrasound (MRgFUS) thalamotomy is a minimally invasive and effective procedure suitable for medication-refractory tremor in patients with ET and patients with PD. However, the skull is the main barrier to MRgFUS thalamotomy therapy and patients are screened by calculating SDR value before treatment. The US FDA recommended SDR value >0.45±0.05 as the inclusion criterion for screening patients with tremor treated by MRgFUS system. However, about 20%-50% of patients with SDR value are lower than this standard, which makes this part of patients excluded and unable to accept this treatment with many advantages such as non-invasive, no need for general anesthesia, and no need for hardware implantation. Therefore, this study intended to evaluate the safety and effectiveness of MRgFUS thalamotomy in the treatment of tremor-related patients with low SDR value, so as to provide clinical basis for more patients with tremor to benefit from this treatment.
Post-craniotomy pain remains a major challenge in patient care following neurosurgery.Flurbiprofen axetil (FA), as an injectable nonselective cyclooxygenase inhibitor, is a widely prescribed NSAID for postoperative pain. As FA is highly lipophilic by merging into emulsified lipid microspheres, it has a high affinity to the surgical incision and inflammatory tissues to achieve targeted drug therapy and prolonged duration of action, thus providing a basis for its local use to achieve efficacy and safety comparable to or greater than systemic administration. In this study, we attempt to evaluate the clinical effects of FA as an adjunct to ropivacaine in pre-emptive scalp infiltration to prevent or reduce pain after craniotomy.
The goal of this clinical trial is to evaluate whether intra-arterial (IA) rhTNK-tPA thrombolysis can improve neurological outcomes in acute large vessel occlusion patients after successful mechanical thrombectomy (MT) recanalization between 4.5- 24 hours from symptom onset. Participants enrolled will be randomly assigned to study or control arm with a 1:1ratio. Study group will receive IA rhTNK-tPA thrombolysis (0.125 mg/kg, Max 12.5mg) plus best medical management, and control receive best medical management alone.
