Abstract:
Objective To analyze the changes in serum levels of Krüppel-like transcription factors(KLF11)and long non-coding RNA small nucleolar RNA host gene 12(lncRNA SNHG12)in patients with intracranial aneurysm(IA),and their predictive value for prognosis.Methods A retrospective analysis was performed on 132 IA patients(IA group)who underwent interventional embolization for IA rupture and bleeding from February 2019 to February 2023,and 60 healthy people who underwent outpatient physical examination during the same period were selected as the control group.Serum levels of KLF11 was detected by enzyme-linked immunosorbent assay(ELISA),the level of lncRNA SNHG12 was detected by real-time fluorescence quantitative PCR(qRT-PCR).According to the modified Rankin scale(MRS)score,IA patients were divided into a good prognosis group(n=98,MRS score 0～2)and poor prognosis group(n=34,MRS score 3～6).Pearson correlation analysis was used to analyze the correlation between serum KLF11,lncRNA SNHG12 and cerebral hemodynamic parameters.Logistic regression analysis was used to analyze the factors affecting the prognosis of IA patients.The receiver operating characteristic curve was used to analyze the prognostic value of serum KLF11 and lncRNA SNHG12 in IA patients.Results The serum KLF11(47.12±6.58ng/L)and lncRNA SNHG12(1.89±0.36)in the IA group were lower than those in the control group(113.89±19.35ng/L,3.24±0.58),and the differences were statistically significant(t=19.695,35.476,all P<0.05).The levels of serum KLF11 and lncRNA SNHG12 in IA group were positively correlated with cerebral blood flow,cerebral blood volume and mean transit time(rKLF11=0.722,0.627,0.752;rlncRNA SNHG12=0.630,0.714,0.766,all P<0.05),and negatively correlated with intracranial pressure(r=-0.658,-0.599,all P<0.05).The proportion of CT Fisher grade 3～4 in IA patients in the poor prognosis group was higher than that in the good prognosis group,and the postoperative complication rate was higher than that in the good prognosis group,the serum KLF11(35.98±6.11 ng/L)and lncRNA SNHG12(1.12±0.30)levels were lower than those in the good prognosis group(50.98±6.90ng/L,2.16±0.39),and the differences were statistically significant(t=4.630～14.151,all P<0.05).CT Fisher grade 3～4,postoperative complications were risk factors for poor prognosis of IA patients(Wald χ2=8.403,12.049,all P<0.001),serum KLF11,lncRNA SNHG12 were protective factors(Wald χ2=5.550,7.904,all P<0.001).The AUC(95%CI)for predicting the prognosis of IA patients with the combination of serum KLF11 and lncRNA SNHG12 was 0.921(0.889～0.942),which was higher than the single detection of serum KLF11 and lncRNA SNHG12 at 0.848(0.805～0.886)and 0.810(0.767～0.852),and the differences were statistically significant(Z=5.886,4.367,all P<0.001).Conclusion The levels of serum KLF11 and lncRNA SNHG12 in IA patients are decreased,which are related to cerebral hemodynamic parameters.The combined detection has a high evaluation value for the prognosis of IA patients.
