Objectives: To describe the clinicopathological characteristics and determinants of survival of patients with mucoepidermoid carcinoma (MEC) of the tongue.
Method: Retrospective population-based study was conducted using the data of patients diagnosed with MEC of the tongue from the Surveillance, Epidemiology, and End Results (SEER) database between 2004 and 2016.
Results: A total of 200 cases of MEC of the tongue were identified.
Background: Adenosquamous carcinoma (ASC) of the salivary gland is a rare malignancy, and the characteristics and prognosis of this disease remain unclear. This study aimed to assess the clinicopathological characteristics of this rare disease and further determine the potential prognostic factors that affect its outcome.
Methods: Data of patients with ASC of the salivary gland were extracted retrospectively from the Surveillance, Epidemiology, and End Results (SEER) database between 1973 and 2016.

Finding suitable scaffold material is always an enormous challenge in the study of bone tissue engineering. Designing and preparing bone scaffolds with biomimetic properties is also a difficult problem for bone reparation projects. This project intends to fabricate radial bio-plasticpoly-3-hydroxybutyrate-4-hydroxybutyrate (P34HB) electrospun fibers scaffold that mimic structural, compositional and stiffness properties via an electro spinning technique.

Ca(PO)(OH) doped with GdPO (HA-GP) was synthesized by a sol-gel technique, and its phase composition depended on the GdPO content. At low doping levels, the phase structure was composed of hydroxyapatite and some Ca(PO), and the content of the latter decreased with the doping content; when the doping content reached to 15 mol%, however, the Ca(PO) amount revealed a significant increase, and GdPO turned to be precipitated. With the addition of GdPO, the microstructure of HA-GP pellets became dense, and the grain size decreased.

However, the design and fabrication of suitable bionic bone scaffolds are still challenging, and the ideal scaffolds in bone tissue engineering should have a three-dimensional porous network, good biocompatibility, excellent biodegradability and so on. The purpose of our research was to investigate whether a bioplasticpoly3-hydroxybutyrate4-hydroxybutyrate (P34HB) electrospun fibre scaffold is conducive to the repair of bone defects, and whether it is a potential scaffold for bone tissue engineering.

Background: Platelet-rich fibrin (PRF) has been widely used in oral implantology and other fields, but benefits of the fresh PRF (FPRF (fresh platelet-rich fibrin)) were consequently limited because of its short-term application. Thus, a protocol for the combination of PRF and lyophilization comes up in the present study to address the issue of PRF storage and delayed clinical application, which has little been reported in this field at home and abroad by now.
Purpose: The aim of the present study was to evaluate the applicability of lyophilized platelet-rich fibrin (Ly-PRF) used as the scaffold material for craniofacial tissue regeneration and to compare its biochemical properties with commonly used fresh PRF.
