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 purpose of this study is to determine the efficacy and safety of the study drug recombinant anti-IL-17A humanized monoclonal antibody in Chinese participants with moderate-to-severe plaque psoriasis.
This is a prospective, multicenter, non-randomized, controlled intervention clinical study.Patients with severe fever with thrombocytopenia syndrome who have been clinically diagnosed and met the study inclusion criteria will be included in the study for analysis. All patients with SFTS will be assigned to different groups according to the ratio of 1:3, including the non-intervention group (conventional treatment group) and the related drug intervention group. Non-intervention group:patients received conventional treatment during hospitalization. Intervention group: Part A group: Patients received methylprednisolone 1-2mg/kg/d（or other glucocorticoid equivalent to methylprednisolone 1-2mg/kg/d) + intravenous immunoglobulin (IVIG) 0.2g-0.4g/kg/d for a total of 3-5 days. If the disease progressed after treatment, the patients was given the dose of rescue therapy (methylprednisolone > 2mg/kg/d or other glucocorticoid equivalent to methylprednisolone > 2mg/kg/d + IVIG 0.4g/kg/d) for another 3-5 days. Part B group: Patients received tocilizumab 4mg/kg once. Part C group: Patients received low molecular weight heparin 100U/kg, qd or q12h IH for 4-7 days. If the platelet count is less than 30 × 10^9/L, the low molecular weight heparin should be discontinued. All patients received conventional treatment. All patients were followed up from the end of treatment to day 28 after completion of treatment.
This study is a prospective observational study. The participants including 40 pregnant women who have been filed and delivered in our hospital will enrolled, collect venous blood will be collected at different stages of pregnancy, delivery, postpartum to detect the concentration of fetal free DNA, the frequency of associated immune cells, and the expression of functional molecules, so as to explore the immunological mechanism of delivery initiation.
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) improves the long-term outcomes for Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) and BC-CML. Relapse remains a major cause of treatment failure even after allo-HSCT. The prevention of relapse is essential for improving the outcome of Ph+ ALL. Pre-emptive tyrosine kinase inhibitor (TKIs) administration based on minimal residual disease (MRD) and BCR-ABL mutation after allo-HSCT might reduce the incidence of relapses and improve survival for patients with Ph+ luekemia. In this study, we will evaluate the safety and efficacy of newly third TKI-HQP1351 therapy post-transplants on Ph+ leukemia after allo-HSCT with MRD positive pre-transplants.
Given the role of B cells in the pathophysiology of chronic graft versus host disease (GvHD), the association between elevated BAFF levels post-transplant in abnormal B-cell homeostasis and chronic GvHD, and the efficacy of belimumab in the inhibition of soluble human B lymphocyte stimulator protein (BAFF) signaling, these proof-of-principle findings support the rational for use of belimumab as treatment of chronic GvHD.The investigators propose a pilot and feasibility study to assess the safety and tolerability, as well as preliminary efficacy, of belimumab a treatment of cGvHD following allogeneic hematopoietic cell transplantation (alloHCT). The investigators' central hypothesis is that belimumab will be well tolerated and have a favorable effect on chronic GvHD,and we explored therapeutic dosage of belimumab.
An observational cross-sectional follow-up study on the quality of life (two aspects, digestive physiological and social psychological functions) of solid pseudopapillary neoplasm of the pancreas (SPN) patients recruited in PUMCH from 2001 to 2026. The quality of life is evaluated by a questionnaire made up of eight validated scales.
The goal of this observational study is to to clarify the focus of lymph node dissection during esophagectomy.. The main question[s] it aims to answer is: - provide a basis for accurate staging and the relationship between OS and lymph node dissection
The study aimed to evaluate 1) if levels of the glycocalyx membrane mucins, including MUC1, MUC4, MUC16 and MUC20, are altered in conjunctival cells of visual display users With and Without Dry Eye Disease, and 2) if mucin levels correlate with dry eye clinical diagnostic data.
The study carries out Sweet Tests and CFTR-mutation screening to explore the prevalence, clinical characteristics, and prognosis of cystic fibrosis, as well as the CFTR-mutation spectrum in Chinese adults with bronchiectasis. The study is multi-centered, prospective, non-interventional, and observational.
The goal of this observational study is to provide a feasible surgical strategy based on Nagata method for patients who require secondary revision surgeries and to verify its long-term aesthetic outcomes. The main question it aims to answer is: • Whether ear reconstruction surgery based on Nagata method can improve the unsatisfactory outcomes of primary reconstruction surgery? Participants who had accepted secondary ear reconstruction based on Nagata method in our department will be required to received questionnaires in the follow-up and their photographs will be collected for reconstructed ear evaluation of its realness through convolutional neural network (CNN) models we previously developed.
