Preparation of Fe–Zn Alloy Biomaterials and Its Effect on Anxiety and Depression of Patients with Coronary Disease After Treatment

Abstract

Relieving anxiety and depression after coronary heart disease surgery is a difficult challenge, and music electroacupuncture can reduce the negative impact of postoperative anxiety and depression on patients. In the study, first, biodegradable materials are studied, the Fe–Zn alloys with different Zn content are prepared by electroforming, and the composition of the electroforming alloy is controlled by changing the composition of the electroforming solution. Because the plant fiber is cheap, and as a reinforcing material, it can endow the composite material with complete degradation properties, Fe–Zn alloy/fiber composite biomaterials are generated in the study. In the experiment, the tensile modulus of the composite is tested first, mahogany wood is selected as the comparative material of the instrument panel, and the feasibility of the material prepared in this research is tested as a music electroacupuncture, and then it is used in the operation of patients with coronary heart disease. The results show that the content of Zn in the electrocasting solution is very close to that in the alloy, indicating that the composition ratio of electrocasting alloy can be controlled by the content of Zn ions in the electrocasting solution. By comparing the density, tensile modulus, and sound propagation velocity of mahogany wood and Zn–Fe plant fiber composite material, it is found that the sound propagation velocity of composite material is similar to that of mahogany wood perpendicular to the texture. Musical electroacupuncture based on Zn alloy/fiber composite biomaterials can effectively increase the weight of patients with coronary heart disease, make their fasting blood sugar concentration close to the level of normal people, and promote the expression of EAAT3 and GAD65 proteins in the hippocampus of the brain.
