The mediating effect of psychological resilience on empathy and professional identity of Chinese nursing students: A structural equation model analysis.

Background: Previous studies have shown that empathy has a positive impact on the professional identity of nursing students. And developing psychological resilience can improve the professional identity of nursing students. However, studies investigating the mechanism of the relationship between empathy and psychological resilience on professional identity remain few.

[5'-flanking regulatory sequence methylation of the Boule gene in the testis tissue of infertile men with Sertoli cell-only syndrome].

Objective: To investigate the 5'-flanking regulatory sequence methylation status of the Boule gene in the testis tissue of infertile men with Sertoli cell-only syndrome (SCOS).

Methods: We collected biopsy samples of the testis tissue from 12 men with obstructive azoospermia (the control group) and 15 cases of SCOS, all without varicocele, cryptorchidism, or infectious disease. We extracted genomic DNA from the testis tissue of the SCOS patients, analyzed the characteristics of the 5'-flanking regulatory sequence of the Boule gene using the bioinformatics method, and detected the methylation status of the Boule gene by sodium bisulfite sequencing.
