RESUMO
Objective:To explore the relationship between new biomarkers in donor blood and delayed graft function after kidney transplantation and evaluate the clinical value of new biomarkers in the diagnosis of DGF (delayed graft function).Methods:For recipients of donor kidney transplantation from August 2016 to December 2017, blood samples were collected from operations of donor organ resection within 12 hours of the day. Enzyme-linked immunosorbent assay (ELISA) was employed for detecting neutrophil gelatinase-associated lipocalin (NGAL), L-type fatty acid binding protein (L-FABP), kidney injury molecule-1 (KIM-1) and interleukin-18(IL-18). They were divided into DGF and EGF (early graft function) groups according to the diagnosis of DGF. The inter-group differences of four new biomarkers were calculated. Receiver operating characteristic curve (ROC curve) was plotted for finding the best positive cutoff value and the sensitivity and specificity of new donor blood marker for diagnosing delayed graft function were calculated.Results:Among them, 8 had postoperative DGF and 62 had none. The overall incidence of DGF was 11.43%. The serum concentration of NGAL was 521.01±132.84 ng/ml in DGF group versus (299.99±100.03) ng/ml in EGF group ( P<0.001). The ROC curve was plotted. With a NGAL concentration >425.15 ng/ml, the sensitivity and specificity for diagnosing DGF were 87.5% and 90.3% respectively. The area under the curve (AUC) was 0.891. The serum concentration of IL-18 was (14.10±12.36) ng/ml in DGF group and (4.61±1.83) ng/ml in EGF group ( P=0.047). With a IL-18 concentration of >5.345 ng/ml, the sensitivity and specificity for diagnosing DGF were 100% and 64.5% respectively. The AUC was 0.914. No significant inter-group difference existed in serum L-FABP/KIM-1. The sensitivity of donor creatinine in the diagnosis of DGF was 62.5%, specificity 75.8% and AUC 0.692. Conclusions:With an excellent level of sensitivity and specificity, an elevated concentration of NGAL/IL-18 in donor blood is superior to traditional creatinine in the diagnosis of DGF after renal transplantation.
RESUMO
Objective:To research the application of flurbiprofen compound small dose fentanyl with self-control vein analgesia after laparoscopic cholecystectomy and the influence on blood coagulation function.Methods:102 cases with laparoscopic cholecystectomy who were treated in our hospital from November 2015 to November 2016 were selected and divided into the control group and the research group,with 51 cases in each group.The patients in the control group were treated with postoperative intravenous analgesia with low-dose fentanyl,while the patients in the research group were treated with postoperative intravenous analgesia with flurbiprofen ester compound low-dose fentanyl.Then the fibrinogen (Fg),activated partial prothrombin time (APTT),prothrombin time (PT),platelet count (PLT),substance P,5-hydrocarbon serotonin (5-HT),interleukin 6,8 (IL-6,IL-8) and complications between two groups were observed and compared.Results:Before treatment,there was no statistically significant difference about the Fg,APTT,PT,PLT,substance P,5-HT,IL-6 and IL-8 between two groups (P＞0.05);After treatment,the Fg,APTT,PT,PLT,substance P,5-HT,IL-6 and IL-8 increased in the two groups,while the research group was lower than that of the control group,and the differences were statistically significant (P＜0.05).The postoperative complication rate of research group was lower than that of the control group (P＜0.05).Conclusion:Flurbiprofen ester compound small dose fentanyl with self-control vein analgesia can relieve coagulation function,and inhibit the levels of inflammatory factors.
