Hepatic ischemia-reperfusion injury (HIRI) has been considered as an inevitable process of liver transplantation. Hepatocyte ferroptosis is a key factor in HIRI development, yet precise mechanism and potential therapies are still unclear. Here, we demonstrated a strong correlation between hepatocyte ferroptosis and the downregulation of poly(rC)-binding protein (PCBP2), which compromised the stability of antiporter system Xc^- (consisted of SL3A2/SLC7A11). Besides, inhibiting PCBP2 contributed to facilitating cofactor p300 to enhance the transcriptional activity of HIF1α, leading to the expression and secretion of HMGB1. Then, released HMGB1 from ferroptotic hepatocytes worsened M1 macrophage recruitment and immune response during HIRI. Additionally, acteoside (ACT) was shown to assist PCBP2 in stabilizing the mRNA stability of Slc3a2 and Slc7a11, as well as enhance the binding affinity of PCBP2-system Xc^-. Beyond that, ACT also supported PCBP2 to limit HMGB1-induced M1 macrophage recruitment through imposing restrictions on p300 and HIF1α. Furthermore, specific knockdown of PCBP2 in hepatocytes directly interposed the therapeutic efficacy of ACT on HIRI mice. In conclusion, ACT alleviated hepatocyte ferroptosis and HIRI via promoting PCBP2 to maintain the stability of system Xc^- and limit HIF1α/p300-HMGB1 signaling. These findings highlight the therapeutic benefits of ACT in treating HIRI and offer insights into innovative therapeutic strategies.

Objective:To investigate the current status of psychosocial adaptation in young and middle-aged patients after colorectal cancer surgery and to explore its influencing factors, providing a basis for the development of targeted interventions.Methods:A total of 200 postoperative young and middle-aged colorectal cancer patients undergoing follow-up at the outpatient department of Shanxi Cancer Hospital from June 2023 to March 2024 were selected by convenience sampling. Data were collected using a general demographic questionnaire, the Self-Report Psychosocial Adjustment to Illness Scale (PAIS-SR), the Family APGAR Index Questionnaire, and the Simplified Ways of Coping Questionnaire (SWCQ). Multiple linear regression analysis was performed to identify factors influencing psychosocial adaptation.Results:A total of 200 questionnaires were distributed, and 191 valid responses were collected, yielding a valid response rate of 95.5%. The total PAIS-SR score of participants was (57.91±23.45). Multiple linear regression analysis revealed that education level, self-perceived economic status, employment status, presence of a stoma, time since surgery, family care, and positive coping style were statistically significant influencing factors ( P<0.05), explaining 46.4% of the variance in psychosocial adaptation. Conclusions:Healthcare providers should pay particular attention to patients with lower educational levels, poor self-perceived economic conditions, unemployment, a stoma, and shorter postoperative duration. Enhancing family care—starting with patient caregivers—and encouraging the use of positive psychological interventions to foster active coping strategies may help improve psychosocial adaptation in young and middle-aged colorectal cancer patients.

Objective:To explore the mediating effect of professional self-efficacy between professional values and willingness to work on gerontological care of nursing students in higher vocational colleges.Methods:A total of 391 nursing students from Chengdu area full-time university were investigated by general information questionnaire, gerontological nursing career motivation questionnaire, professional values scale, and professional self-efficacy scale. Pearson correlation analysis and descriptive statistical analysis were performed by SPSS 21.0. Amos 26.0 was used to establish mediating effect model and verify the mediating effect.Results:The total score of 391 nursing students' willingness to work on gerontological care was (47.05±6.93), the willingness to work on gerontological care was positively correlated with professional self-efficacy and professional values ( r = 0.826, 0.775, respectively, all P<0.01), and professional self-efficacy played a partial mediating role between professional values and willingness to work on gerontological care, accounting for 64.82% of the total effect. Conclusions:The willingness to work on gerontological care of nursing students in higher vocational colleges is at a middle level. Professional values not only directly affect the willingness to work on gerontological care, but also indirectly take function through the professional self-efficacy. Professional self-efficacy plays a mediating role in professional values and willingness to work on gerontological care of nursing students in higher vocational colleges.
