[Key Techniques of Three-Dimensional Electrophysiology Catheter Positioning Based on Magnetic-Electric Fusion].

In cardiac ablation procedures, the accuracy of catheter positioning determines the authenticity of the cardiac model and the accuracy of the ablation target. This article reviews the literature on catheter positioning in electrophysiology and summarizes the key technologies for catheter positioning, such as magnetic-electric fusion and interference suppression. Addressing the limitations of electric and magnetic positioning individually, the paper elaborates on the rationale for catheter positioning technology based on magnetic-electric fusion.

Accelerated Wound Healing in Diabetic Rat by miRNA-185-5p and Its Anti-Inflammatory Activity.

Aim: Addressing both inflammation and epithelialization during the treatment of diabetic foot ulcers is an important step, but current treatment options are limited. MiRNA has important prospects in the treatment of diabetic foot refractory wound ulcers. Previous studies have reported that miR-185-5p reduces hepatic glycogen production and fasting blood glucose levels.

LPS-pretreatment adipose-derived mesenchymal stromal cells promote wound healing in diabetic rats by improving angiogenesis.

Mesenchymal stem cells (MSCs) play a key role in wound healing, and the advantages of pretreated MSCs in wound healing have previously been reported. In the present study, we investigated the impact of LPS pretreated human adipose-derived MSCs on skin wound healing in diabetic rats. We found that some improvements occurred through improving angiogenesis.
