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.
This is a prospective, one-arm, phase II clinical study of Tislelizumab Combined With Anlotinib and Chemotherapy for Second-line Treatment of Advanced or Metastatic Pancreatic Cancer
T-cell lymphoblastic lymphoma (T-LBL) is the second most common subtype of non-Hodgkin lymphoma (NHL) in children and adolescents. With current treatment, event-free survival (EFS) rates vary between 75%~85%. Two different MTX intensification strategies are used commonly: HD-MTX with leucovorin rescue, and Capizzi-style MTX without leucovorin rescue plus PEG-ASP (C-MTX). Although superior outcome of patients with T-ALL receiving C-MTX compared with HD-MTX on the AALL0434 trial, the 2 approaches had not been compared directly in patients with T-LBL. There remains controversy on PET/CT interpretation in children with NHL. Large prospective studies in pediatric patients with T-LBL regarding PET/CT value for this is scarce. Around 1% pediatric patients with T-LBL will not achieve remission at the end of Induction (induction failure). The optimal treatment for this small subgroup is largely unclear. The BFM HR Blocks usually are applied to these patients even though the efficacy is unknown. Novel targeted therapies are needed for use. Dasatinib is identified as a targeted therapy for T-cell ALL in preclinical drug screening.
This study aims to observe the impact of perioperative body temperature on postoperative pain and pain sensitization for the patients with laparoscopic surgery. Based on this study the investigators aimed to explore the effect of perioperative hypothermia on postoperative pain.
At present, COVID-19 vaccine is considered as the safest, economic and effective measure to prevent and control COVID-19. Adaptive immunity, including humoral immunity and cellular immunity, plays a role in anti-viral responses. Cellular immunity includes virus specific B cells and T cells, which can provide long-term memory immunity. For acute viral infection, neutralizing antibody is of great significance in preventing infection, while memory cell immunity can maintain a good broad-spectrum and persistence in controlling mutant strains, which is a key factor in controlling viral replication after infection and reducing severe disease and death. However, there is no systematic study on the specific immune response and infection risk of novel coronavirus, and there is no definite conclusion on which specific protective immune response induced by vaccine can reduce the risk of infection. Therefore, this study aims to establish a prospective real-world cohort, analyze the correlation between multiple baseline immune protection indicators and infection risk, follow up the population with breakthrough infection, and monitor the dynamic specific immune response to COVID-19 in peripheral blood and respiratory mucosa. This study will provide an important scientific basis for us to scientifically assess the risk of individual infection with COVID-19.
Hypercholesterolemia is a risk factor for the occurrence and development of atherosclerosis. Recent animal studies have found that increased serum cholesterol level is associated with peripheral Treg cell senescence, but clinical evidence is still lacking. The purpose of this study is to analyze the correlation between human peripheral Treg cell senescence and serum total cholesterol level using clinical blood samples, thus laying a foundation for the establishment of novel therapeutic strategies for atherosclerosis based on the regulation of Treg cell senescence.
The purpose of this study is to evaluate the safety and efficacy of Telitacicept in adult patients with active lupus nephritis.
This study used a randomized, open, blank control design. A total of 6800 patients over 15 years old with latent mycobacterium tuberculosis infection who met the inclusion criteria but did not meet the exclusion criteria were randomly assigned to the experimental group and the blank control group in a 1:1 ratio, with 3400 patients in each group. The experimental group was alternately injected with 1 dose of microcard every two weeks (0-2-4-6-8-10 weeks) in the left and right hip muscle deep, with a total of 6 doses. The blank control group was not injected with drugs.
The elderly patients over 65 years old with breast cancer have concomitant diseases, poor tolerance to conventional treatment, and the specific prognosis of breast cancer is relatively good. Previous studies on breast cancer have almost excluded elderly breast cancer patients, and conventional treatment schemes cannot meet the clinical diagnosis and treatment needs of elderly breast cancer patients. The establishment of a prognosis model for elderly breast cancer patients can provide personalized treatment programs. This is important for prolonging the survival time of patients and improving the quality of life. This project plans to observe the relationship between prognosis and pathological staging, molecular typing, and concomitant diseases of elderly breast cancer patients in combination with immune genes, and establish a prognosis model of elderly breast cancer and verify it. This project is expected to establish a new prognostic model for elderly breast cancer patients, accurately judge the prognosis of patients, and provide a new basis for hierarchical and personalized treatment of elderly breast cancer.
Ophthalmic emergencies are acute vision-threatening disorders, for which a delay in prompt emergency response could result in catastrophic vision loss. Triage is an effective process for ensuring that timely emergency care is provided despite limited resource by prioritizing patients to appropriate orders for visits. Historically, registered nurses classify emergency patients based on personal experiences with high variation. Additionally, primary healthcare providers have been conventionally at the forefront of providing first aid care. However, most of ocular emergencies are wrongly diagnosed or referred due to non-eye specialists' limited knowledge and training in the ophthalmology. Here, the investigators established and validated an artificial intelligence system, EE-Explorer, to triage eye emergencies and assist in primary diagnosis using metadata and ocular images. This system has been integrated into a website to be prospectively validated in the real world.
Acute ST segment elevation myocardial infarction (STEMI) has a high disability mortality rate, and timely reperfusion treatment can significantly reduce the mortality of patients. Emergency PCI is the preferred strategy for STEMI treatment recommended by domestic and international guidelines. The long-term existence of stents can never completely avoid the formation of thrombosis in the stents and affect the relaxation and contraction of criminal blood vessels. Drug coated balloon provides a new concept and technology of interventional therapy for coronary artery disease in the form of "intervention without implantation". Through balloon dilation of local blood vessels to release anti proliferative drugs to coronary artery wall and inhibit intimal hyperplasia, it can not only treat serious coronary artery disease, improve coronary blood supply and vascular function, but also not leave permanent implants in the blood vessels; The main pathogenesis of STEMI is thrombosis based on the rupture or erosion of coronary atheromatous plaque. In terms of pathophysiological mechanism, drug coated balloons are also suitable for STEMI patients without obvious thrombosis or severe dissection after full pretreatment. The two-dimensional lumen images obtained by traditional coronary angiography can not directly reflect the vessel wall, so we can not evaluate the actual size of the vessel, plaque characteristics and the effect of intervention through coronary angiography; Optical coherence tomography (OCT) uses near-infrared scanning to produce high-resolution tissue microscopic images with a resolution of up to 10 μ m. It can clearly observe the three-layer structure of coronary artery, find abnormal intima structure, and more clearly identify thrombosis, dissection, plaque erosion or collapse in coronary artery, providing more valuable information for optimizing interventional treatment. Therefore, the application of drug coated balloon under the guidance of OCT in STEMI can provide a more accurate and optimized diagnosis and treatment scheme for STEMI patients.
