Objective To investigate the levels of serum soluble CD14 subtype(Presepsin)and serum amyloid protein A(SAA)in patients with colorectal cancer after laparoscopic surgery,and their predictive value for early anastomotic leakage.Methods From October 2021 to April 2024,126 patients with laparoscopic colorectal cancer were divided into the non-anastomotic leakage group(control group,n=103)and the anastomotic leakage group(observation group,n=23)based on whether anastomotic leakage occurred within 3 days after the operation.Clinical information was collected from both groups and compared between groups.Enzyme linked immunosorbent assay(ELISA)was applied to detect the postoperative serum levels of Presepsin and SAA in two groups.Pearson method was applied to investigate the correlation between postoperative serum levels of Presepsin and SAA in patients with colorectal cancer after laparoscopic surgery.The multivariate Logistic regression model was applied to analyze the key factors influencing the occurrence of anastomotic leakage in the early postoperative period in patients with colorectal cancer after laparoscopic surgery.The receiver operating characteristic curve(ROC curve)was applied to evaluate the predictive value of serum Presepsin and SAA levels for early anastomotic leakage in colorectal cancer patients after laparoscopic surgery.Results Compared with the control group,the proportion of patients with tumours≥7 cm from the anus was significantly reduced and intraoperative bleeding was significantly increased in the observation group,the differences were statistically significant(P<0.05).The postoperative levels of serum Presepsin and SAA in the observation group were obviously higher than those in the control group,the differences were statistically significant(P<0.05).There was an obvious positive correlation between serum levels of Presepsin and SAA in patients with colorectal cancer after laparoscopic surgery(r=0.749,P=0.016).Serum Presepsin levels higher than 389.23 pg/mL and SAA expression levels higher than 25.10 mg/L were independent risk factors for the occurrence of early anastomotic leakage after surgery in patients with colorectal cancer after laparoscopic surgery.A tumor distance from the anus of≥7 cm was a protective factor.The area under the curve(AUC)of serum Presepsin and SAA alone and in combination for detecting early anastomotic leakage in patients with colorectal cancer after laparoscopic surgery was 0.834(95%CI:0.757～0.894),0.801(95%CI:0.720～0.866),and 0.897(95%CI:0.830～0.944).The combined detection was superior to the separate detection of Presepsin and SAA(Zcombination-Presepsin=2.085,Zcombination-SAA=2.010,both P<0.05).Conclusion Serum levels of Presepsin and SAA are elevated in patients with colorectal cancer after laparoscopic surgery,and their combined detection has high predictive value for early anastomotic leakage.

Objective:To explore the mediating effect of chronic disease self-efficacy between fatigue and social support in breast cancer patients undergoing chemotherapy.Methods:This study was a cross-sectional study. From July 2020 to April 2021, convenience sampling was used to select 376 patients with breast cancer undergoing chemotherapy in the Shandong Provincial Hospital Affiliated to Shandong First Medical University as the research object. The General Information Questionnaire, Fatigue Scale-14, Chronic Disease Self-Efficacy Scale and Social Support Rating Scale were used to investigate the patients. Structural equation modeling was used to test the mediating effect among variables. A total of 376 questionnaires were distributed, and 372 valid questionnaires were recovered, with a valid recovery rate of 98.94%.Results:Among 372 breast cancer patients undergoing chemotherapy, the total scores of the Fatigue Scale-14, Chronic Disease Self-Efficacy Scale and Social Support Rating Scale were (10.61±1.81) , (5.00±2.53) and (43.42±12.59) , respectively. Chronic disease self-efficacy was positively correlated with social support in breast cancer patients undergoing chemotherapy ( r=0.493-0.648, P<0.01) , and social support was negatively correlated with fatigue ( r=-0.703--0.234, P<0.01) , and self-efficacy was negatively correlated with fatigue ( r=-0.729--0.220, P<0.01) . Chronic disease self-efficacy played a partial mediating role between fatigue and social support in breast cancer patients undergoing chemotherapy (β=-0.335, P<0.01) , and the mediating effect accounted for 47.59% of the total effect. Conclusions:Social support can indirectly affect fatigue through chronic disease self-efficacy in breast cancer patients undergoing chemotherapy. Nurses should focus on improving the chronic disease self-efficacy and social support of breast cancer patients undergoing chemotherapy.
