Abstract:
Objective To investigate the relationship between the expression levels of serum multiple epithelial growth factor like domains 6(MEGF6),sterile alpha motif(SAM)domain,scr homology 3(SH3)domain and nuclear localization signals 1(SAMSN1)and acute lung injury(ALI)in patients with sepsis.Methods A total of 182 patients with sepsis(sepsis group)who were admitted to Huazhong University of Science and Technology Union Jiangnan Hospital from February 2021 to February 2024 were selected and divided into ALI group(n=60)and non-ALI group(n=122)according to whether they were complicated with ALI or not.80 healthy people who underwent physical examination during the same period were selected as the control group.Serum MEGF6 and SAMSN1 levels were detected by enzyme-linked immunosorbent assay(ELISA).Pearson correlation analysis was used to analyze the correlation between serum MEGF6,SAMSN1 and clinical indicators.Multivariate Logistic re-gression analysis was used to analyze the risk factors of sepsis complicated with ALI.The receiver operating characteristic(ROC)curve was used to analyze the value of serum MEGF6 and SAMSN1 in the evaluation of sepsis complicated with ALI.Results Serum MEGF6(37.52±7.87 ng/L)and SAMSN1(24.26±7.45 ng/L)in the sepsis group were lower than those in the control group(78.17±15.26 ng/L,62.31±14.12 ng/L),and the differences were statistically significant(t=28.397,28.477,all P<0.001).Serum MEGF6(29.22±7.64 ng/L)and SAMSN1(13.28±7.12 ng/L)in the ALI group were lower than those in the non-ALI group(41.60±7.90 ng/L,29.66±7.67 ng/L),and the differences were statistically significant(t=10.045,13.961,all P<0.05).Se-rum MEGF6 and SAMSN1 in patients with sepsis complicated with ALI were negatively correlated with APACHE II score and SOFA score(r=-0.811～-0.728,all P<0.05),and positively correlated with oxygenation index(OI)(r=0.689,0.640,all P<0.05).APACHE II score and SOFA score were risk factors for sepsis complicated with ALI.Serum MEGF6(OR=0.769,95%CI:0.612～0.965)and SAMSN1(OR=0.778,95%CI:0.617～0.980)were protective factors(Wald χ2=5.140,4.525,all P<0.05).The area under the curve(AUC)of serum MEGF6,SAMSN1 alone and combined in the evaluation of sepsis complicated with ALI were 0.840,0.811 and 0.903,respectively.The combined detection was greater than the single detection,and the differences were statistically significant(Z=4.602,4.318,all P<0.05).Conclusion The serum levels of MEGF6 and SAMSN1 in patients with sepsis are decreased,which are the influ-encing factors of sepsis complicated with ALI.The combined detection of the two has a high evaluation value for sepsis complicated with ALI.
