Carotid Revascularization for Radiation Induced Carotid Artery Stenosis
Cervical radiotherapy (RT) has greatly reduced the mortality of patients with malignant head and neck tumors, which, however, causes a higher risk of carotid artery stenosis, namely, radiation-induced carotid artery stenosis (RICS) and results in a significant increased risk of ischemic stroke. The systematic review and meta-analysis conducted by our …
Study of Anlotinib Hydrochloride Capsules in the Treatment of Locally Advanced or Metastatic Radioiodine-Refractory Differentiated Thyroid Carcinoma
The study aims to observe and investigate the efficacy and safety of Anlotinib capsules in patients with locally advanced or metastatic radioiodine-refractory differentiated thyroid carcinoma in the real world, and to summarize the treatment experience in a broad population.
Retinal Vascular Manifestations in Patients With Common Internal Diseases on OCTA Tomography Angiography
Hypertension, diabetes mellitus, and dyslipidemia are common internal diseases, and all diseases are atherosclerosis risk factors. Previous studies applied color fundus photography to analyze retinal vascular changes (including exudation, hemorrhage, neovascularization, etc.) in patients with hypertension or diabetes, but the examination results could not be quantified. This study intends to …
Tumor Microenvironment in Gastric Cancer Patients Treated With Combined Immunotherapy and Chemotherapy
The goal of this study is to analyze the tumor microenvironment (TME) in gastric cancer patients treated with combined immunotherapy and chemotherapy. The main questions it aims to answer are: Provide profiles of TME between pre-treatment and post-treatment to gain insights into the mechanisms of immunotherapy combined with chemotherapy in …
CtDNA After Chemotherapy in Elderly Patients With Acute Leukemia
This study will monitor CtDNA After Chemotherapy in Elderly Patients With AL
Risk Prediction Model for Exacerbating Phenotype in Patients With Chronic Obstructive Pulmonary Disease
This study is planned to be conducted based on the cohort of patients with severe chronic obstructive pulmonary disease in our hospital. Based on gut microbiota, random forest was used to search for potential diagnostic biomarkers in patients with frequent acute exacerbation and controls with non frequent acute exacerbation; Construct …
Correlation Between Perioperative Autonomic Function and Post-induction Hypotension in Elderly Patients
Elderly patients have a higher risk of post-induction hypotension (PIH). The decreased cardiovascular autonomic function at baseline in elderly patients may contribute to the development of PIH. The objective of our study is to effect of preoperative cardiovascular autonomic modulation in PIH, we will recruit elderly patients who are going …
Safety and Efficacy of SBRT in the Treatment of Thoracic Malignant Tumors at Different Sites
SBRT (stereotactic radiotherapy) can provide a higher dose to the target area without increasing the risk of surrounding normal tissue / organ injury in selective cases. At present, SBRT has been widely used in radiotherapy of lung cancer and it can also play a better local control for lung metastasis. …
Genetic and Molecular Risk Profiles of Pediatric Malignant Brain Tumors in China
Primary malignant central nervous system (CNS) tumors are the second most common childhood malignancies. Amongst, medulloblastomas are the most common malignant brain tumor of childhood and occur primarily in the cerebellum. According to molecular characteristics, medulloblastomas were classified into four subtypes: WNT, SHH, Group3 and Group4 and different prognosis were …
MRI Study of Blood-brain Barrier Function in CADASIL
Diffusion prepared pseudo-continuous ASL (DP-pCASL) is a newly proposed MRI method to noninvasively measure the function of blood-brain barrier (BBB). The investigators aim to investigate whether the water exchange rate across the BBB, estimated with DP-pCASL, is changed in patients with CADASIL, and to analyze the association between BBB water …
