Development and Assessment of a Predictive Model for Ki-67 Expression Using Ultrasound Indicators and Non-Morphological Magnetic Resonance Imaging Parameters Before Breast Cancer Therapy.

To formulate a predictive model for assessing Ki-67 expression in breast cancer by integrating pre-treatment ultrasound features with non-morphological magnetic resonance imaging (MRI) parameters, encompassing functional and hemodynamic indicators. A retrospective study was conducted on 167 patients. All patients underwent a breast mass biopsy for histopathological and Ki-67 analysis prior to neoadjuvant chemotherapy (NAC) treatment.

Assessing Left Ventricular Systolic Function in Patients with Pregnancy-Induced Hypertension Using Three-Dimensional Speckle Tracking Technology.

Objective: This study investigates the clinical utility of three-dimensional speckle tracking technology in assessing left ventricular systolic function in pregnancy-induced hypertension syndrome (PIH).

Methods: We retrospectively enrolled 70 patients with diagnosed PIH treated at our institution between July 2019 and August 2021 as the study group. A total of 70 healthy pregnant women undergoing routine antenatal examinations at the same institution during the same period were included in the control group.

Combined diagnosis of ultrasonic elastography and BI-RADS classification increases diagnostic value in female patients with breast neoplasms.

Objective: This study was designed to investigate the clinical value of ultrasonic elastography combined with the Breast Imaging Reporting and Data System (BI-RADS) classification in patients with breast neoplasms.

Methods: A retrospective observational study was conducted on 89 patients with breast neoplasms hospitalized from June 2017 to June 2018. All the enrolled patients had received ultrasound examinations.

Scutellarin Exerts Anti-Inflammatory Effects in Activated Microglia/Brain Macrophage in Cerebral Ischemia and in Activated BV-2 Microglia Through Regulation of MAPKs Signaling Pathway.

Background: Scutellarin, an herbal compound, can effectively suppress the inflammatory response in activated microglia/brain macrophage(AM/BM) in experimentally induced cerebral ischemia; however, the underlying mechanism for this has not been fully clarified. We sought to elucidate if scutellarin would exert its anti-inflammatory effects on AM/BM through the MAPKs pathway.

Materials And Methods: Western blot and immunofluorescence labeling were used to determine the expression of the MAPKs pathway in AM/BM in rats subjected to middle cerebral artery occlusion (MCAO) also in lipopolysaccharide (LPS)-activated BV-2 microglia in vitro.

Scutellarin promotes microglia-mediated astrogliosis coupled with improved behavioral function in cerebral ischemia.

Scutellarin, an anti-inflammatory agent, has been reported to suppress microglia activation. It promotes astrocytic reaction but through activated microglia. Here we sought to determine more specifically the outcomes of scutellarin treatment in reactive astrocytes in rats subjected to middle cerebral artery occlusion (MCAO).
