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.
Excessive accumulation or abnormal distribution of adipose tissue is a recognized risk factor for ischemic stroke. However, the impact of overweight or obesity on clinical outcomes of ischemic stroke is uncertain. The proposition of obesity paradox in stroke patients makes secondary prevention ambiguous for patients with ischemic stroke and overweight or obesity. Body mass index (BMI) or abdominal visceral fat area was used to measure obesity in previous studies. Epicardial adipose tissue (EAT) is a unique visceral fat, which has higher expression of proinflammatory genes than subcutaneous fat and abdominal visceral fat. And inflammation is closely related to the prognosis of ischemic stroke. In this study, the investigators assume EAT volume or attenuation evaluated by chest computed tomography (CT) scan might affect the prognosis of patients with acute ischemic stroke (AIS). Patients with the first acute ischemic stroke will be stratified into tertile groups based on EAT volume or attenuation. The primary endpoint measure is the proportion of patients with a favorable recovery of nerve function deficiency assessed by Modified Rankin Scale （mRS≤2） at 90 days after the onset of symptoms. Secondary endpoints include the following: the percentage of functional recovery measured by the Barthel Index (BI) at day 90 after stroke onset, the propotion of clinical improvement (with an improvement of ≥ 4 points on the National Institute of Health Stroke Scale score or the resolution of the neurologic deficit) or neurological deterioration (with a decline by ≥ 4 points in the total National Institute of Health Stroke Scale score) at day 7 after stroke onset, incidence of hemorrhagic transformation and mortality within 7 days of symptom onset.
The purpose of this study is to compare the efficacy and safety of human umbilical cord mesenchymal stem cells and low-dose IL-2 in the treatment of LN
The purpose of this observational study is to evaluate properties of lipiodol-idarubicin emulsion mixed with the best regimen obtained in vitro study, including stability, viscosity，visibility under X-ray and deposition, in order to maximize the efficacy of idarubicin-cTACE for HCC.
In 1% of men with infertility, obstructive azoospermia (OA) may occur in congenital absence of the vas (CAVD) or idiopathic obstructive azoospermia . Many studies have shown that the pathogenic genes of OA are CFTR and ADGRG2 genes, and the inheritance mode is autosomal recessive. Although the conventional assisted reproductive technology(PESA/TESA) can help these patients have children, male patients who carry mutations of the disease-causing genes (CFTR and ADGRG2) will also pass on their mutations to the next generation, which will increase the risk of male offspring infertility. Therefore, genetic detection of CFTR and ADGRG2 genes is very necessary for CAVD patients before assisted reproduction. Genetic diagnosis plays a key role in preventing the disease to the offspring.
The purpose of this study is to assess the safety and efficacy of SKB264 monotherapy in subjects with selected advanced solid tumors.The study is divided into two parts: the Part Ⅰ consists of 5 cohorts, and the Part Ⅱ for expansion. Eligible subjects will receive SKB264 monotherapy, until there is no longer clinical benefit, intolerable toxicity, discontinuation of study treatment required by the subject, or other protocol-specified treatment discontinuation criteria, whichever occurs first.
Diabetic retinopathy (DR) is the main cause of blindness among working-age adults in the world. Proliferative diabetic retinopathy (PDR) is the severe stage of DR, which is characterized by neovascularization of the retina. Vitreous hemorrhage and traction retinal detachment caused by PDR often require vitrectomy. The purpose of vitrectomy is to remove vitreous hemorrhage, peel off the preretinal proliferative membrane and help restore the retina. With the deepening of people's understanding of diabetes and the development and application of various hypoglycemic drugs, the life expectancy of patients with diabetes continues to prolong. Therefore, the goal of vitrectomy in patients with DR is not only to prevent blindness, but also to maintain good vision for a long time. The purpose of this study is to analyze the risk factors related to the occurrence of long-term low vision postoperatively and establish a risk prediction model, which can help patients adjust their psychological expectations reasonably and promote communication between doctors and patients.
Fat composition of the spinal tumors is positively correlated with classification and differential diagnosis of benign and malignant tumors.
This study is a post-approval commitment study, and is designed to further evaluate the safety and efficacy of isavuconazole in a relatively larger Chinese population who will receive isavuconazole treatment in a post-marketing setting. This is a single arm, prospective, multi-center study. This study is seeking Chinese patients with proven, probable or possible Invasive Fungal Disease (IFD) caused by Aspergillus species or other filamentous fungi. All the participants will receive isavuconazole treatment. The longest treatment duration in this study is 84 days (up to 180 days for participants diagnosed with IM). The primary objective is to characterize the safety and tolerability of isavuconazole through observing the treatment emergent adverse events.
This study aims to address critical knowledge gaps by investigating the effects of trait conscious movement processing propensity on real-time (state) conscious movement processing propensity, postural stability, and muscle efficiency in older adults at risk of falling in Hong Kong with high and low trait conscious movement processing propensities, while standing in a challenging environment with different levels of standing task difficulties. The study results would contribute to our scientific understanding of the mechanisms of conscious movement processing in older adults while maintaining standing balance in a challenging environment. It could inform the follow-up investigations for the development of the most appropriate psychomotor standing balance re-education intervention in rehabilitation so as to mitigate the effect of conscious movement processing and the risk of falling in older adults. The findings from the proposed research could ultimately help improve the outcome of fall rehabilitation programmes and reduce the impact of falls in the older adults in Hong Kong.
