Background: Patients with acute pancreatitis (AP) have different sites of pancreatic involvement. The aim of this study was to investigate the differences in magnetic resonance imaging (MRI) findings and clinical features of different sites of involvement (subtypes) in AP, with a view to complement and complete the classification of AP based on anatomical imaging features.
Methods: We consecutively collected data from inpatients with AP from January 2018 to October 2022 at a tertiary care hospital.
Effects of Jintiange on the healing of osteoporotic fractures in aged rats.
J Orthop Surg Res
December 2024
Objective: To examine the effects of Jintiange on enhancing the healing of osteoporotic fractures in aged rats.
Methods: An osteoporotic fracture model of femur was established using 70 SD rats (aged > 12 months), which were randomly numbered and divided into an experimental group and a control group, each with an equal sample size (n = 35). The experimental group received Jintiange capsule ingredients via intragastric administration, while the control group received an equal volume of saline via the same method.
