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 study is a single-center, prospective, single-arm exploratory study aimed at evaluating the efficacy and safety of trifluridine/tipiracil in combination with cetuximab in the treatment of third-line and above RAS/BRAF wild-type metastatic colorectal cancer.
This registry aims to evaluate the long-term prognosis and valve durability of transcatheter aortic valve replacement (TAVR) in a real-world setting. Baseline characteristics, procedural data, and clinical outcomes will be collected in a prospective and observational manner.
Tourette syndrome is a refractory type of tic disorder. Previous clinical studies have confirmed that Tuina has a good effect on TS, but the mechanism of action is still uncertain. Studies have found that the pathogenesis of TS may be related to immune factors, and patients will accompanied by the overflow of inflammatory factors such as interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) during the onset of the disease. Other studies have found that the serum levels of IgG1, IgG2, IgG3, IgG4, IgGM, IgGA, IgGE, complement C3 and complement C4 are closely related to the pathogenesis of TS, and the abnormal humoral immune response mediated by food intolerance has an important impact on the pathogenesis of mental illness in children. The immune system plays a very complex role in TS. Based on this, we hypothesized that there may be differences in serum humoral immune effector levels between children with TS and healthy children, whether these differences are related to the consumption of certain allergenic foods or not, and so does Tuina spinal balancing can improve the clinical symptoms of children with TS by changing the levels of inflammatory and immune factors in peripheral serum. This study studied the peripheral mechanism of humoral immune effector mediated by Tourette syndrome and the intervention effect of Tuina through comprehensive scale analysis and advanced laboratory technology, which will provide a scientific theoretical basis and a safe and effective method for the treatment of multiple tics, and will have broad application prospects.
HMA maintenance therapy is expected to benefit overall survival (OS) and relapse free survival (RFS) in AML patients with favorable risk.
In this project, IDEAL-IQ technology and PDFF and R2* image-based imaging methods are used to analyze the intrinsic relationship between preoperative vertebral bone marrow fat content, magnetic susceptibility properties of bone tissue and bone strength (bone volume and bone mass), to explore the mechanism of vertebral re-fracture after PVP / PKP, and to explore the imaging markers for the risk of postoperative vertebral re-fracture after PVP / PKP. To construct a precise and individualized risk assessment model of vertebral re-fracture after PVP/ PKP by combining clinical risk factors, preoperative quantitative MRI parameters (PDFF, R2*) and imaging characteristics, so as to achieve the goal of objectively and accurately evaluating the risk of vertebral re-fracture at the early stage of the postoperative period (1 year).
Background/Rationale: Neurofibromatosis type 1 (NF1) affects about 1 in every 3000 people worldwide. Globally, 30~50% NF1 patients will develop plexiform neurofibromas (PNs), which grow rapidly in early childhood and can cause disfigurement, motor dysfunction, pain, airway dysfunction, visual impairment and bladder and bowel dysfunction. This systemic disease imposes a heavy psychosomatic and financial burden on patients and their caregivers. In NF1 patients, the lifetime risk of MPNST developed from PN is 8% to 13%. The mean age for NF1-associated death was approximately 20 years lower than that for the general population. Limited epidemiological and clinical data of Chinese NF1 patients is available to date. And the treatment pattern of Chinese NF1-PN patients is also unknown. Objectives and Hypotheses: It is a descriptive study without formal hypothesis. The primary objective of this study is determining the percentage of NF1 patients who develop PN. The secondary objectives of this study include describing the clinical characteristics, tumor progression and treatment pattern of NF1-PN. The exploratory objective is exploring the epidemiological characteristics of other NF1 manifestations. Methods: Study design: The study is a retrospective multi-center chart review study. Data Source(s): All the data will be collected by CRF from inpatient and outpatient electronic medical records in every study site from January 1, 2019 to December 31, 2022. Study Population: Patients who attended the study sites between January 1, 2019 - December 31, 2022 and were diagnosed with NF1 were included in this study. Statistical Analysis: This study is purely descriptive without any formal hypotheses. Missing data for baseline characteristics will be assessed and addressed as a categorical variable with a level for missingness. All reported measures will be summarized in the study tables. Point estimates and their 95% CIs will be presented in the final analyses.
Factors influencing the prognosis of patients with heart failure with preserved ejection fraction (HFpEF) have been extensively studied. Previous studies have found that elevated serum total bilirubin levels are associated with cardiac death, heart failure readmission, and all-cause mortality in patients with chronic heart failure. However, the relationship between direct bilirubin and prognosis in patients with HFpEF is unclear.
To investigate the efficacy of GnRHa plus letrozole in obese progestin-insensitive EEC patients.
This study plans to select 100 AV patients and randomly divide them into two groups in a 1:1 ratio: the experimental group will be treated with MRF combined with oral isotretinoic acid for 8 consecutive weeks, with a total of 3 MRF treatments at weeks 1, 4, and 8. The control group received oral administration of isotretinoic acid alone for 8 weeks. The main observation indicators are the percentage of effective skin injury clearance achieved by subjects at week 20, as well as the change in ECCA acne scar score compared to baseline at week 20. I hope this study can clarify that the combination therapy of the two can achieve the effects of improving efficacy, shortening treatment course, reducing recurrence, not increasing adverse reactions, and reducing the risk of scar formation.
