Obstructive Sleep Apnea Influences Efficacy of PD-1-Based Immunotherapy Against Non-Small Cell Lung Cancer
This prospective, observational cohort study aims to explore the influence of obstructive sleep apnea(OSA) on the efficacy of PD-1-based immunotherapy in patients with non-small cell lung cancer(NSCLC). Patients who had no prior treatment for advanced NSCLC and are intended to receive PD-1/PD-L1 antibody will be recruited. According to sleep monitor …
The Recurrence Mechanism of Venous Tinnitus After Boney Wall Reconstruction Based on Multimodal Imaging and Multiphysics Coupling
Venous tinnitus (VT) is seriously affecting the quality of life of five million patients in China. Bony wall reconstruction is the main treatment method, but the postoperative recurrence rate exceeds 30%, and the specific mechanism is unclear. Based on our previous work, a scientific hypothesis was put forward: the key …
Quantitative Susceptibility Biomarker and Brain Structural Property for Cerebral Cavernous Malformation Related Epilepsy
Cerebral cavernous malformation (CCM)-related epilepsy (CRE) impairs the quality of life in patients with CCM. Patients could not always achieve seizure freedom after surgical resection of the lesion, suggesting an inadequate treatment and evaluation of the epileptogenic zone or network. Iron deposition in cerebral cavernous malformations has been postulated to …
Comparison of MBR + Suture Tape and Anatomic Reconstruction for CLAI in GJL Cases: A Prospective Cohort Study
GJL is a risk factor for postoperative recurrent instability following an MBR for CLAI. BPR with suture tape augmentation and anatomic reconstruction may provide more strength and stability. However, BPR with suture tape augmentation may lead to rejection of the suture tape, while anatomic reconstruction may be associated with more …
Functional Magnetic Resonance-Based Observations of Brain Networks in Moyamoya Disease Patients Under Anesthesia
Moyamoya disease is characterized by progressive stenosis of the genesis of the distal internal carotid arteries bilaterally and progressive generation of compensatory pathological vascular networks at the basis cranii, and these pathological vasculature has poor vascular reactivity. Perioperative circulatory management of patients with smoky vessels to ensure perfusion of brain …
Microecology and Immunity in Patients With Anti-MDA5 Antibody Positive Dermatomyositis and Interstitial Lung Disease
The purpose of this study was to analyze the relationship between the microbial community, host immunity and the presence or absence of concurrent rapidly progressive interstitial lung disease patients with anti-MDA5 antibody positive dermatomyositis.
Association Between Stroke and Adrenal Incidentalomas
Adrenal incidentalomas (AIs) are commonly encountered in transsection imaging which purpose not for suspected adrenal disease. However, part of AIs in patients is associated with Stroke. Stroke is a diseases which could cause of disability and death worldwide. In clinical practice, detailed information about the association between stroke and AIs …
COMPETE Cohort Study
Migraine attacks are episodic disorder that affects approximately 12% of the population, and studies have shown that 41-48% of migraineurs have a combination of patent foramen ovale (PFO). Clinical Observational studies have been linking PFO occlusion with the effectiveness in improving migraine symptoms and reducing the frequency of attacks. However, …
The Impact of Autonomic Function on Atrial Fibrillation Recurrence After Pulmonary Vein Ablation
This is a prospective and observational study. The investigator speculated that the use of DC in patients with paroxysmal AF can serve as a predictor for early and late AF recurrence following CPVI.
A Real-World Registry Investigating TReprostInil sodiUM in Pulmonary Hypertension (Re-TRIUMPH)
A Real-World Registry investigate Treprostinil sodium used in patients with Pulmonary Hypertension (Re-TRIUMPH).
