A Three-dimensional Simulation Based on Radiofrequency Electrothermal Coupling fields for Skin Rejuvenation.

Radiofrequency (RF) current is used as an effective non-ablative method for skin rejuvenation. However, mixed results have been reported using different home-use RF devices. In order to evaluate the safety and effectiveness of home-use RF devices, this study has provided a three-dimensional (3D) simulation procedure based on the electrothermal coupling model for home-use RF devices.

Effect of geometric parameters of electrodes on skin heating for the design of non-ablative radiofrequency device.

Background: Non-ablative radiofrequency (RF) has been widely used in clinical and at-home cosmetics devices. RF electrode geometry can influence the heat distribution in the tissue. This study analyzes the influence of geometric parameters of the electrode on the heat distribution in the layered tissue.

[The role of epithelial cells in the formation and development of nasal polyps].

Nasal polyps, as a subtype of chronic sinusitis, is prone to clinical recurrence and seriously affects the quality of life of patients, but its pathogenesis is unclear. It is considered to be a chronic inflammation of the nasal-sinus mucosa under the combined action of multiple factors. Among them, nasal mucosal epithelial injury and shedding are the main pathological features.
