Malignant pheochromocytoma invading the ureteral wall muscle layer: A case report.

Pheochromocytoma is a neuroendocrine tumor for which surgical resection is the main treatment.Malignant pheochromocytoma is very rare. Here,we present a case of adrenal pheochromocytoma invading the ureteral wall muscle layer, which resulted in left adrenal and left nephrectomy.

Artificial intelligence-based MRI radiomics and radiogenomics in glioma.

The specific genetic subtypes that gliomas exhibit result in variable clinical courses and the need to involve multidisciplinary teams of neurologists, epileptologists, neurooncologists and neurosurgeons. Currently, the diagnosis of gliomas pivots mainly around the preliminary radiological findings and the subsequent definitive surgical diagnosis (via surgical sampling). Radiomics and radiogenomics present a potential to precisely diagnose and predict survival and treatment responses, via morphological, textural, and functional features derived from MRI data, as well as genomic data.

Blueberry anthocyanins improve liver fibrosis by regulating NCOA4 ubiquitination through TRIM7 to affect ferroptosis of hepatic stellate cells.

This study aims to investigate the role and molecular mechanism of anthocyanin in improving liver fibrosis through ferroptosis, providing a basis for drug development and targeted therapy. In this study, a mouse model of liver fibrosis was established using CCl, and the anthocyanin treatment groups were administered 100 mg/kg anthocyanin daily via gavage. Furthermore, real-time fluorescent quantitative PCR (qRT-PCR), Western blotting (WB), and enzyme-linked immunosorbent assay were used to assess liver fibrosis indicators and liver injury markers.

Anthocyanins improve liver fibrosis in mice by regulating the autophagic flux level of hepatic stellate cells by mmu_circ_0000623.

Liver fibrosis is a key step in the progression of various chronic liver diseases to liver cirrhosis and even liver cancer, it is also an important link affecting prognosis. Therefore, this study aimed to investigate the therapeutic effect of anthocyanins on liver fibrosis and the molecular mechanism of mmu_circ_0000623 in anthocyanin therapy. In this study, CCL was used to build a mouse liver fibrosis model, and the treatment groups were treated with 100 and 200 mg/kg of anthocyanins daily by gavage.

Diagnostic value of magnetic resonance imaging ectopic posterior pituitary hyperintense signal in pituitary macroadenoma.

Objective: When the lesions in the sellar region are large, they can involve both the inside and outside the sella, which brings challenges to the differential diagnosis of pituitary macroadenoma and lesions other than macroadenoma. Therefore, this study explored the diagnostic value of an ectopic posterior pituitary hyperintense signal (EPPHS) in pituitary macroadenoma and its possible causes.

Methods: The clinical and imaging data of 131 patients with sellar tumors or tumor-like lesions involving both intrasellar and extrasellar regions in the Affiliated Hospital of Guizhou Medical University from February 2011 to December 2021 were analyzed retrospectively.

Computed Tomography, Magnetic Resonance Imaging, and Pathological Features of Gliosarcoma.

Objective: To investigate the clinical, imaging, and pathological features of gliosarcoma.

Methods: The clinical data of 14 patients with gliosarcoma confirmed by surgery and pathology at our hospital between 2010 and 2021 were analyzed retrospectively, and the relevant literature was reviewed.

Results: In all 14 cases, the gliosarcoma was located in the supratentorial brain parenchyma and involved a single lesion.

Computed Tomography and Magnetic Resonance Imaging in the Diagnosis of Cerebral Paragonimiasis in Children.

Objective: To investigate the computed tomography (CT) and magnetic resonance image (MRI) manifestations of cerebral paragonimiasis (CP) in children and to improve the understanding of the disease.

Methods: The cranial CT and MRI data of 12 children with positive intradermal tests for -specific antigens were retrospectively analyzed. Additionally, the lesion locations, morphology, and imaging characteristics were analyzed.
