Objective: To assess the effect of psychocardiology-based nursing intervention on cardiac function and self-efficacy in elderly patients with angina pectoris.
Methods: A total of 127 elderly patients with angina pectoris admitted to the First Affiliated Hospital of Xi'an Jiaotong University from December 2022 to December 2023 were divided into two groups: the control group (n=63) received routine nursing care, while the observation group (n=64) received psychocardiology-based nursing intervention in addition to routine care. The psychological status, self-efficacy, cardiac function, and severity of angina were compared between the two groups before and after intervention.
A facile sol-gel spin coating method has been proposed for the synthesis of spin-coated ZnO nanofilms on ITO substrates. The as-prepared ZnO-nanofilm-based W/ZnO/ITO memory cell showed forming-free and tunable nonvolatile multilevel resistive switching behaviors with a high resistance ratio of about two orders of magnitude, which can be maintained for over 10 s and without evident deterioration. The tunable nonvolatile multilevel resistive switching phenomena were achieved by modulating the different set voltages of the W/ZnO/ITO memory cell.

The W/TiO/FTO memory device exhibits a nonvolatile bipolar resistive switching behavior with a high resistance ratio (R/R) of about two orders of magnitude. The conduction behaviors of the W/TiO/FTO memory device are attributed to the Ohmic conduction mechanism and the Schottky emission in the low resistance state and the high resistance state, respectively.
