Abstract:
Objective To investigate the relationship between serum solute carrier family 7 member 11(SLC7A11)and Janus kinase 2(JAK2)levels and the severity and prognosis of acute non-variceal upper gas-trointestinal bleeding(ANVUGIB).Methods A total of 108 patients with ANVUGIB who were treated in the hospital from April 2019 to April 2023 were selected and divided into severe group(31 cases),moderate group(44 cases)and mild group(33 cases)according to the severity of ANVUGIB.The patients were divided into poor prognosis group(41 cases)and good prognosis group(67 cases)according to their prognosis.An-other 50 healthy volunteers who underwent physical examination in the hospital during the same period were selected as the control group.Serum SLC7A11 and JAK2 levels were detected by enzyme-linked immunosor-bent assay.Spearman correlation analysis was used to analyze the correlation between serum SLC7A11 and JAK2 levels and Framingham risk score(FRS)and Glasweg-Blatchford bleeding score(GBS).Multivariate Logistic regression was used to analyze the influencing factors of poor prognosis in patients with ANVUGIB.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of serum SLC7A11 and JAK2 for poor prognosis in patients with ANVUGIB.Results The serum SLC7A11 level was significantly lower and the serum JAK2 level was significantly higher in the three groups of ANVUGIB patients than in the control group(all P＜0.05).As the severity of the disease increased,the serum SLC7A11 level gradually de-creased,and the serum JAK2 level,FRS and GBS scores gradually increased(all P＜0.05).In ANVUGIB pa-tients,serum SLC7A11 level was negatively correlated with FRS and GBS scores,and serum JAK2 level was positively correlated with FRS and GBS scores(all P＜0.05).Compared with the good prognosis group,the poor prognosis group had significantly higher proportion of patients with bleeding volume＞400 mL,red blood cell distribution width,FRS score,GBS score,and JAK2 level,and significantly lower levels of hemoglo-bin and SLC7A11(P＜0.05).Bleeding volume＞400 mL and elevated JAK2 level were risk factors for poor prognosis in ANVUGIB patients,while elevated SLC7A11 level was a protective factor(all P＜0.05).The ar-ea under the curve of combined SLC7A11 and JAK2 in predicting poor prognosis of ANVUGIB patients was better than that of each index alone(Zcombination-SLC7A11=3.086,Zcombination JAK2=2.330,P=0.020,0.030).Conclu-sion The decrease of SLC7A11 level and increase of JAK2 level in patients with ANVUGIB can effectively e-valuate the severity and prognosis of patients,and the combination of the two can predict the prognosis of pa-tients with ANVUGIB.
