Ultrahigh-frequency Ultrasonography (UHFUS) in Detection of Small Pulmonary Ground Glass Opacity (GGO)
The purpose of this study is to assess the feasibility of UHFUS on detection of GGOs in excised lung tissue and investigate UHFUS features of GGO in vitro. Each GGO was detected by palpation, UHFUS and open biopsy in sequence. The comparison of detection rate and time consumption were analyzed …
Multimodal MRI for MRgFUS Central Lateral Thalamotomy in Neuropathic Pain
To explore the pathogenesis underlying neuropathic pain as well as the mechanisms of pain relief after Magnetic resonance-guided focused ultrasound (MRgFUS) Central Lateral Thalamotomy through multi-model MRI study, and to identify imaging biomarkers for triaging patients and predicting the clinical outcomes. Craniofacial neuropathic pain is one of the most serious …
Geno-radiomics Based Model for Evaluation of Immunotherapy and Targeted Therapy for Advanced Soft Tissue Sarcoma
In this study, a new post-processing image technology - radiomics is used to screen out parameters of CT and MRI images, which could effectively evaluate the efficacy and prognosis of immunotherapy plus targeted therapy for soft tissue sarcoma (STS). A reliable and effective model for predicting the prognosis of STS …
Brain Network Analysis of Anesthesia Characteristics in Patients With pDoC Based on PSG
The goal of this prospective, exploratory and observational study is to learn about in healthy volunteers and patients with prolonged disorders of consciousness(pDoC). The main questions it aims to answer are: Observe the similarities and differences of polysomnography between pDoC patients and healthy volunteers, and analyze the characteristic brain network …
The Clinical Outcomes of the Modified Broström vs Anatomic Reconstruction Operation in CLAI and GJL
Investigators designed this prospective cohort study to compare the clinical outcomes of modified Broström operation and anatomical reconstruction for the treatment of CLAI and GJL.
The Effects of Anesthetics on Brain Network Connectivity in Patients With Supratentorial Glioma
Perioperative anesthesia can affect postoperative cognitive function. In our previous study, intraoperative dexmedetomidine (Dex) infusion reduced the incidence of delirium within the first 5 days after brain tumor. However, the mechanism is still unclear. With the development of neuroimaging, multimodal neuroimaging technology provide a new method to explore the underlying …
Effect of Pre-existing Adjacent Segment Degeneration on Long-term Effectiveness After Lumbar Fusion Surgery
This is a prospective single-center study. Patients requiring posterior lumbar interbody fusion (PLIF) for lumbar degenerative disease are prospectively enrolled and followed. Important adjacent pre-existing degeneration factors include discs degenerated, facets and ligamentum flavum tropism which could lead to spinal canal stenosis (SCS). This study will focus on the effects …
Safety and Efficacy of Balloon Pulmonary Angioplasty in China
Balloon pulmonary angioplasty (BPA) is a potential treatment for non-operable patients with chronic thromboembolic pulmonary hypertension (CTEPH). The aim of this study was to evaluate the safety and efficacy of BPA in CTEPH patients not amenable to pulmonary endarterectomy(PEA) or suffered from persistent CTEPH after PEA.
Registry of X-linked Adrenoleukodystrophy
This study is a observational study conducted through recruiting X-linked adrenoleukodystrophy (X-ALD) patients, to build a comprehensive evaluation and long-term follow-up platform for X-ALD patients, and to provide a theoretical basis for the treatment and management of X-ALD patients.
A Multicenter Clinical Trial of Urine DNA Testing for Bladder Cancer in China
The primary objective of this study is to assess the safety and effectiveness of Human Multigene Methylation Detection Kit (Fluorescent PCR Method) for help diagnose bladder cancer by comparing with clinical standard method (includes medical imaging (MRI, CT, etc.), cystoscopy, pathological examination).
