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.
Bullous pemphigoid (BP) is a chronic autoimmune subepidermal blistering disease primarily affecting the elderly with a significant risk of mortality and morbidity. Various inflammatory cells such as eosinophils, lymphocytes, neutrophils and their granulopoiesis play an important role in the pathogenesis of BP. Infiltration of peripheral blood eosinophils, lymphocytes, and neutrophils into the skin is considered a major feature of BP, making it a heterogeneous disease with different histologic and clinical subtypes. This clinical study was conducted to further investigate the impact of different pathologic phenotypes of BP on the treatment and prognosis of the disease. A retrospective epidemiologic investigative approach was used，and case collection included demographic information, medical history, clinical manifestations, and histopathologic features. Including gender, age, duration of disease, number of days of hospitalization, mucosal involvement, clinical diagnosis before admission, histopathological diagnosis, laboratory tests, concomitant diseases, treatment and its changes in laboratory indexes before and after treatment.
The goal of this observational study is to learn about the role of MRI evaluation based on FVH-DWI mismatch principle in preoperative evaluation of endovascular thrombolectomy. The main questions it aims to answer are: - The consistency between MRI and perfusion examination in determining EVT indications. - The consistency of functional independence rate between patients screening with MRI and perfusion.
We aim to prospectively assess the burden, management and therapeutic approaches and outcomes of acute respiratory failure requiring respiratory support, during the winter months in China. The purpose of this study is to provide new and current data on the disease burden of acute respiratory failure and ARDS. It will answer the following questions: - The frequency and disease burden of acute respiratory failure in China; - The incidence of ARDS based on the new global definition within this patient cohort. - The mortality of ARDS within this cohort, and how does this vary based on ARDS categories and severity. - The long-term outcomes (1-year mortality and survivor quality of life) of ARDS within this cohort. - The nature course of ARDS (different stages and severity of ARDS). - The respiratory support management strategies, such as recruitment maneuvers, prone positioning, ECCO2R, and ECMO. - The use of drugs during ICU stays, including glucocorticoid, anticoagulant, nitric oxide, sivelestat, Xuebijing, and ulinastatin. - The economical burden of acute respiratory failure within this patient cohort. - The impact of occupation, incomes and education levels on the incidence and mortality of ARDS.
A multicenter, randomized, double-blind, placebo-controlled clinical trial was designed. The study included two experimental groups (low-dose ZKY001 eye drops group and medium-dose ZKY001 eye drops group) and a placebo control group, with 60 subjects in each group.
The goal of this clinical trial is to study about the clinical effect of Intra-articular Injection on Temporomandibular Joint Dysfunction The main question it aims to answer is: • Can Intra-articular Injection help improve the Temporomandibular Joint Dysfunction Participants will be randomly assigned into the experimental group and the control group, all under comprehensive treatment. The experimental group will be given Intra-articular Injection additionally, The study lasts 15 days for each patient. Researchers will compare the assessments between the two groups to see if Intra-articular Injection can help improve the Temporomandibular Joint Dysfunction
cricopharyngeal achalasia refers to incomplete or non-open functional opening of the cricopharyngeal muscle, and after repeated swallowing of food, it still cannot pass through the cricopharyngeal muscle, remaining in the epiglottic valley and the piriform fossa, and even regurgitated into the nasal cavity . Neurogenic diseases, myogenic diseases and head and neck tumors are the common causes. Patients with chronic underfeeding lead to malnutrition, reduced quality of life, affecting the outcome of the disease. At present, the treatment measures for cricopharyngeal achalasia at home and abroad include balloon dilation technique, surgical incision, botulinum toxin injection. The dilation of the balloon is easy to cause mucosal edema and damage. Local infection, massive hemorrhage, local nerve injury and other complications often occur in cricopharyngotomy. Botulinum toxin injection relieves muscle spasms and is now widely used to treat dystonia. Common injection localization methods include CT, ultrasound, electromyography and endoscopy. Ultrasound-guided injection is a new technique of visualization, simple and non-radiation injection guidance, which can observe the injection process and drug injection position in real time. Fixation with a balloon can further improve the accuracy of the injection. In this study, botulinum toxin was injected into the cricopharyngeal muscle by ultrasound combined with balloon.
This is an open-label, single-arm, phase I clinical trial with dose escalation designed to investigate the safety, tolerability, and pharmacokinetic properties of Human CD19-CD22 Targeted T Cells Infusion. The primary objectives are to preliminarily assess the impact of Human CD19-CD22 Targeted T Cells Infusion in patients with relapsed/refractory B-cell acute lymphoblastic leukemia and to explore the appropriate dose and reinfusion schedule for phase II. Eligible participants, including those with Central Nervous System Lymphoma, B Cell Lymphoma (BCL), Acute Lymphocytic Leukemia (ALL), Acute Lymphoblastic Leukemia (ALL), B Acute Lymphoblastic Leukemia (B-ALL), Refractory Non-Hodgkin Lymphoma, Refractory Chronic Lymphocytic Leukemia (CLL), Refractory B Acute Lymphoblastic Leukemia (B-ALL), Diffuse Large B Cell Lymphoma, Lymphoid Leukemia, and MRD-positive cases, can participate. Eligibility will be determined through a comprehensive assessment, including disease evaluations, a physical examination, Electrocardiograph, Computed Tomography (CT), Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET), and blood tests. Prior to the infusion of CD19-CD22 CAR+ T cells, participants will undergo chemotherapy. After the infusion, participants will be closely monitored for potential side effects and the effectiveness of CD19-CD22 CAR+ T cells. Certain study procedures may be conducted during hospitalization.
This trial was a randomized, double-blind, sham-controlled trial.Thirty patients with post-stroke dysphagia were randomly assigned to the repetitive transcranial magnetic stimulation(rTMS) group (n=15) or sham rTMS group (n=15). Both groups received conventional swallowing rehabilitation, and in addition, the rTMS group received 5hz repetitive transcranial magnetic stimulation on the healthy side. Swallowing function was assessed at admission and after two weeks of treatment using the the Standardized Swallowing Assessment (SSA), the Penetration-Aspiration Scale (PAS), the Fiberoptic Endoscopic Dysphagia Severity Scale(FEDSS), the Functional Oral Intake Scale (FOIS), and the functional near-infrared spectroscopic(fNIRS).
This phase 1 study will consist of two parts: Phase 1a is a single-dose study, and will evaluate the safety, tolerability, pharmacokinetics (PK) and preliminary pharmacodynamics (PD) in healthy participants. Phase 1b is a multiple doses study, and will evaluate the safety, tolerability, PK and preliminary PD in participants with rheumatoid arthritis (RA).
As a diagnostic test, this study aims to explore the effectiveness of systems based on wearable devices in identifying mood disorders in children and adolescents.
