Purpose: To establish the 3D-FE model libraries for the elements of the RPD.
Methods: Based on the 3D geometric model libraries of the RPD and normal stomatognathic system, using the software, such as Powershape,Pro/E and Ansys5.5, transformed data, trimmed models, or rebuilt it, established many kinds of FE model elements, then combine these elements in the whole model, connected and trimmed, at last created several kinds of FE model libraries.
Results: This study established eight kinds of FE model libraries, including the occlusal rests, clasps, bases, artificial teeth, and connectors, etc, nearly two hundreds FE model elements.
Conclusion: The established models have a satisfied geometric configuration; these elements combined well in the whole model, and can be easily call-in and edit.

The biodegradation of synthetic polymers offers a promising solution for sustainable plastic recycling. Polyurethanes (PUR) stand out among these polymers due to their susceptibility to enzymatic hydrolysis. However, the intricate 3D structures formed by PUR chains present challenges for biodegradation studies, both computational and experimental.

Background: Anticoagulants are the primary means for the treatment and prevention of venous thromboembolism (VTE), but their clinical standardized application still remains controversial. The present study intends to comprehensively compare the efficacy and safety of various anticoagulants in VTE.
Methods: Medline, Embase, and Cochrane Library from their inception up to August 2023 were searched to compare the efficacy and safety of various anticoagulants in VTE.
