Objective To analyze cysteinylaspartate specific proteinase-3,caspase-7,caspase-9,AMP activated protein kinase(AMPK)in the diagnosis and prognosis evaluation of sepsis.Methods Sixty patients with sepsis from the Affiliated Hospital of Xiangnan University from March 2020 to March 2023 were selected as the observation group,and another 60 healthy individuals from the physical examination center of the hospital during the same period were selected as the control group.Acute physiology and chronic health evaluationⅡ(APACHEII)score was used to evaluate the severity of the patient's condition.Serum caspase-3,caspase-7,caspase-9,AMPK and APACHEII scores were detected,and compared between the two groups.These parameters were compared with serum Caspase-3,caspase-7,caspase-9,AMPK and APACHEII scores in different disease severity groups.The patients were divided into survival group(50 cases)and death group(10 cases)according to prognosis.Serum Caspase-3,caspase-7,caspase-9,AMPK and APACHEII scores were compared between the two groups,and the correlation between serum caspase-3,caspase-7,caspase-9,AMPK and APACHEII scores were analyzed by Pearson.Receiver operating characteristic(ROC)was drawn,the area under the curve(AUC)was calculated,the predictive efficacy of serum caspase-3,caspase-7,caspase-9 and AMPK in patients death with sepsis were analyzed.Results The serum levels of caspase-3,caspase-7,caspase-9,AMPK,and APACHEII score in the observation group were higher than those in the control group,and the differences were statistically significant(t=19.501～44.219,all P<0.05).The serum caspase-3,caspase-7,caspase-9,AMPK,and APACHEII scores in the sep-tic shock group were higher than those in the severe and mild groups,and the differences were statistically significant(t=2.091～6.946,all P<0.05).The serum caspase-3,caspase-7,caspase-9,AMPK,and APACHEII scores of the death group were higher than those of the survival group,and the differences were statistically significant(t=4.576～8.835,all P<0.05).Serum caspase-3,caspase-7,caspase-9 and AMPK were positively correlated with APACHEII scores(r=0.382～0.406,all P<0.05).The AUC of combined detection of serum caspase-3,caspase-7,caspase-9,and AMPK for predicting death in sepsis patients was 0.863,with 95%confidence interval of 0.805-0.958.which was greater than that of single indicator detection,and the difference is statistical-ly significant(Z=2.912～2.294,all P<0.05).Conclusion Serum caspase-3,caspase-7,caspase-9,and AMPK in sepsis patients showed abnormally high expressions,which were closely related to disease severity and prognosis.Combined detection could improve the sensitivity and specificity of death prediction,which has certain reference value.
