Clinical Study of Imaging and Endoplant-related Mechanical Complications After Long Segment Fixation and Fusion of Degenerative Lumbar Scoliosis (DLS)
There is a high probability of mechanical complications in patients with degenerative lumbar scoliosis after long segment fixation and fusion, and there are few studies on distal borderline kyphosis deformity/failure. This study was designed to retrospectively analyze the patients with degenerative lumbar scoliosis (DLS) who underwent posterior selective decompression and …
Treatment of Patients With Takayasu Arteritis Complicated With Pulmonary Artery Involvement
Evaluate the effect of medical treatment and percutaneous transluminal pulmonary angioplasty on takayasu arteritis with pulmonary artery involvement evaluate the efficacy of FAPI in predicting the activity and treatment efficacy of takayasu arteritis with pulmonary artery involvement
Multi-delay Arterial Spin Labeling Application in Acute Ischemic Stroke
This study explores the value of the non-invasive quantitative evaluation system for cerebral blood flow perfusion function in the diagnosis of stroke. Compared with traditional perfusion techniques, multi-delay arterial spin labeling (ASL) is validated to determine the accuracy of perfusion level, ischemic penumbra and other indexes in patients with acute …
Safety and Efficacy of SBRT in the Reirradiation for Ultra-central Thoracic Malignant Tumors
The reirradiation of thoracic tumor is difficult. The possibility of surgery or re course radiotherapy is very small. In the NCCN guideline, only systemic treatment is recommended. However, the effective rate of systemic treatment is low. SBRT has the characteristics of high dose in tumor target area and low dose …
Early Warning and Classification Model for Acute Non-traumatic Chest Pain
Acute non-traumatic chest pain is one of the common causes of presentation in emergency patients, but the causes of acute non-traumatic chest pain are complex, the severity of the condition varies greatly, and the specificity of symptoms is not high. Machine learning and intelligent auxiliary models can greatly shorten the …
Surgical Treatment and Molecular Marker Exploration of Locally Recurrent Colorectal Cancer
This study intends to explore the clinicopathological characteristics and survival prognosis of locally recurrent colorectal cancer patients with different treatment modes by retrospectively analyzing the medical records of locally recurrent colorectal cancer patients who received hospitalization in our center. Transcriptome sequencing and public databases were used to screen for molecular …
Orelabrutinib Therapy in Patients With r/r B-cell Lymphoma Intolerant to Other Bruton Tyrosine Kinase Inhibitors
To evaluate the safety and effecacy of Orelabrutinib therapy in patients with relapsed or refractory B-cell lymphoma (including R /rCLL/SLL and R /rMCL) who are intolerant to ibrutinib/zanubrutinib or other BTK inhibitors
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 …
