Regulatory focus as a mediator in the relationship between nurses' organizational silence and professional identity.

AIMS: This work aims to analyse the current state of the professional identity of Chinese nurses; examine the relationship amongst regulatory focus, organizational silence and professional identity and determine how regulatory focus affects the relationship between professional identity and organizational silence. DESIGN: This study conducted a cross-sectional survey. METHODS: From June to August 2023, 420 nurses from six hospitals in Hunan Province, China, were selected through convenience sampling and surveyed by using a general information questionnaire, the regulatory focus scale, the organizational silence scale and the professional identity scale. The relationship amongst the regulatory focus, organizational silence and professional identity of nurses was examined by utilizing SPSS 25.0 and the mediating role of regulatory focus between organizational silence and nurses' professional identity was examined by applying AMOS 24.0. RESULTS: Nurses had a moderate level of professional identity. Professional identity was positively correlated with regulatory focus and negatively correlated with organizational silence. Regulatory focus was negatively correlated with organizational silence. Mediation effect studies revealed that organizational silence and professional identity were partially mediated by regulatory focus. CONCLUSION: In accordance with research showing that nurses' organizational silence can indirectly affect professional identity via regulatory focus, clinical nursing managers should concentrate on the interaction amongst these three variables to strengthen professional identity. IMPACT: The results of this study serve as a reminder to nurses to select a preventive or promotive focus based on their career objectives and to effectively express their views to enhance their professional identity. This also reminds nursing managers assess nurse-led regulatory focus, identify their underlying qualities and understand their professional aspirations and career orientation, create a good atmosphere for advice and encourage nurses to express their views, so as to improve nurses 'professional identity. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Comparison of clinical efficacy of laparoscopic splenectomy versus open splenectomy for idiopathic thrombocytopenic purpura: A meta-analysis.

BACKGROUND: The purpose of this study is to compare the clinical efficacy of laparoscopic splenectomy (LS) and open splenectomy (OS) in the treatment of Idiopathic thrombocytopenic purpura. METHODS: We systematically searched PubMed, Web of science, EMBASE, Clinicaltrials.gov, and Cochrane Central Register for studies (study published from July 1992-January 2020). This study analyzed the clinical effect of LS and OS on idiopathic thrombocytopenic purpur. RESULTS: This study showed that compared with OS, the LS's Overall response (OR: 0.60, 95% confidence interval (CI): 0.23-1.59, P = .30), Complication (OR: 0.59, 95% CI: 0.18-1.94, P = .38), Accessory spleen(OR: 1.70, 95% CI: 0.98-2.98, P = .06), Wound infections (OR: 0.65, 95% CI: 0.26-1.59, P = .34), Pancreatic fistula (OR: 0.73, 95% CI: 0.16-3.30, P = .68), was no significant, the Operative time (weighted mean difference (WMD): 49.33, 95% CI: 36.29-62.37, P < .00001)was longer, and the Estimated blood loss (WMD: -172.59, 95% CI: -319.96 to -25.22, P = .02), Postoperative length of stay (WMD: -4.68, 95% CI: -7.75 to -1.62, P = .003)was less. CONCLUSIONS: The therapeutic effect of LS was the same as that of OS in Overall response Complication Accessory spleen, while The operative time was longer, the Estimated blood loss was less, and the postoperative length of stay was shorter.

Protective Role of Somatostatin in Sepsis-Induced Intestinal Barrier Dysfunction through Inhibiting the Activation of NF-κB Pathway.

Somatostatin (SST) has a protective role in intestinal injury, inflammatory response, and intestinal mucosal barrier in rats with acute pancreatitis. However, its function in sepsis-induced intestinal barrier dysfunction remains largely unknown. A mouse sepsis model was constructed, and SST was injected into the tail vein. Then, hematoxylin and eosin staining (HE) was used to detect the intestinal barrier dysfunction. Enzyme-linked immunosorbent assay was used to detect the level of tumor necrosis factor α- (TNF-) α, interleukin- (IL-) 6, and interleukin- (IL-) 10 in the ileum. Expressions of tight junction proteins, zonula occludens- (ZO-) 1 and Claudin-1, and NF-κB p65 in the ileum were detected using western blot and immunohistochemistry as needed. Furthermore, JSH-23 as an inhibitor of the NF-κB pathway was injected into sepsis mice with SST or not. Mice with sepsis showed an obvious intestinal barrier dysfunction with decreasing specific somatostatin receptor subtype (SSTRs), and increasing TNF-α, IL-6, and IL-10 in the ileum. SST could relieve the injury, the decrease of SSTRs, and the increase of TNF-α and IL-6 induced by sepsis and also further enhanced the expression of IL-10. Further analysis showed that ZO-1 and Claudin-1 were reduced in the ileum by sepsis but enhanced by SST. NF-κB p65 was promoted in the ileum by sepsis but inhibited by SST. Further experiments confirmed that NF-κB inhibitor JSH-23 could repair the intestinal barrier dysfunction and enhance the protective effect of SST on the intestinal barrier. SST, with a protective effect on intestinal barrier dysfunction through suppression of NF-κB, could be a potential therapeutic drug for sepsis-induced intestinal barrier dysfunction.
