Exosome-derived miR-23a-5p inhibits HCC proliferation and angiogenesis by regulating PRDX2 expression: MiR-23a-5p/PRDX2 axis in HCC progression.

microRNAs (miRNAs) are closely related to the progression of hepatocellular carcinoma (HCC). Cancer-derived exosomes play an essential role in the establishment of the HCC microenvironment. However, the possible effects and underlying mechanisms of exosome (exo) microRNA-23a-5p (miR-23a-5p) in the progression of HCC remain unknown.

The Predictive Role of Inflammatory Biomarkers for Treatment Response and Progression-Free Survival in Patients with Hepatocellular Carcinoma Receiving Hepatic Arterial Infusion Chemotherapy with FOLFOX Regimen: A Preliminary Study.

Objective: This retrospective study aimed to investigate whether pre-treatment inflammatory biomarkers, including the prognostic nutritional index (PNI), monocyte-lymphocyte ratio (MLR), systemic immune inflammation index (SII), and platelet-lymphocyte ratio (PLR), could predict treatment response and prognosis in patients with hepatocellular carcinoma (HCC) receiving hepatic arterial infusion chemotherapy (HAIC) with the oxaliplatin, leucovorin, and fluorouracil (FOLFOX) regimen.

Methods: Based on the cut-off values identified using the receiver-operating characteristic (ROC) curve, 124 patients with HCC who received HAIC with the FOLFOX regimen were divided into low- and high-score MLR, PLR, PNI, and SII groups. Univariate and multivariate regression analyses were performed to identify independent predictors of treatment response and progression-free survival (PFS).

Prediction of therapeutic response of unresectable hepatocellular carcinoma to hepatic arterial infusion chemotherapy based on pretherapeutic MRI radiomics and Albumin-Bilirubin score.

Purpose: To construct and validate a combined nomogram model based on magnetic resonance imaging (MRI) radiomics and Albumin-Bilirubin (ALBI) score to predict therapeutic response in unresectable hepatocellular carcinoma (HCC) patients treated with hepatic arterial infusion chemotherapy (HAIC).

Methods: The retrospective study was conducted on 112 unresectable HCC patients who underwent pretherapeutic MRI examinations. Patients were randomly divided into training (n = 79) and validation cohorts (n = 33).

Predictive value of DCE-MRI and IVIM-DWI in osteosarcoma patients with neoadjuvant chemotherapy.

Objective: To investigate the predictive value of dynamic contrast enhanced MRI (DCE-MRI) and intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI) for clinical outcomes of osteosarcoma patients with neoadjuvant chemotherapy.

Methods: The present prospective single-arm cohort study enrolled 163 patients of osteosarcoma during July 2017 to July 2022. All patients received the same treatment strategy of neoadjuvant chemotherapy.

Application of diffusion tensor imaging for detecting structural changes in the brain of schizophrenic patients.

Objective: Schizophrenia is a severe psychiatric illness. Although magnetic resonance imaging has been widely used for detecting brain structural and functional abnormalities in patients with schizophrenia, the findings are highly inconsistent between reports. This study investigates structural changes in the brains of schizophrenic patients.

A quantitative study of magnetic susceptibility-weighted imaging of deep cerebral veins.

Objective: To evaluate the value of magnetic susceptibility-weighted imaging (SWI) for measuring deep cerebral venous diameter.

Methods: The diameters of 150 deep cerebral veins were measured by SWI and digital subtraction angiography (DSA) in 50 patients.

Results: SWI showed whole cerebral veins as clear soft vessels, but with a crooked hypointense linear structure along the sulcus.
