Clinical observation of Porcine Collagen Membrane + artificial Bovine Bone Granules Guided tissue regeneration combined with Autologous CGF in the treatment of severe periodontitis bone defect.

Objective: To investigate and analyze the clinical observation of porcine collagen membrane + artificial bovine bone granules guided tissue regeneration (GTR) combined with autologous concentration of growth factors (CGF) in the treatment of severe periodontitis bone defect.

Methods: A total of 94 patients with severe periodontitis bone defects admitted to Shanxi Bethune Hospital from January 2019 to January 2022 were included. They were divided into two groups by simple randomization method.

Astragaloside IV promotes the proliferation and migration of osteoblast-like cells through the hedgehog signaling pathway.

The present study aimed to investigate the effects of astragaloside IV on osteoblast‑like cell proliferation and migration, in addition to the underlying signaling pathway. In order to observe the effect on proliferation, a Cell Counting Kit‑8 assay and flow cytometry were used. To detect cell migration ability, cell scratch and Transwell cell migration assays were performed.

Nodal Stage: Is It a Prognostic Factor for Submandibular Gland Cancer?

Purpose: Submandibular gland cancer is relatively rare. The purpose of this study was to estimate 5-year overall survival (OS) and disease-free survival (DFS) and to identify prognostic factors associated with OS and DFS for submandibular cancer.

Materials And Methods: The authors implemented a retrospective cohort study and enrolled a sample of patients with submandibular gland cancer.
