Objective To perform a regression analysis on the predictive value of serum micro-RNAs(miR)for early neurological deterioration(END)in patients with branch atheromatous dis-ease(BAD).Methods A total of 134 BAD patients admitted in our department from February 2020 to February 2023 were enrolled,and according to the END status,they were divided into de-terioration group(28 cases)and non-deterioration group(106 cases).Serum levels of miR-130a,miR-210,miR-141-3p and miR-29a-3p were measured at admission.NIHSS score was used to eval-uate the END status at admission and at 7 d after admission.Binary logistic regression analysis was adopted to construct a model of above four miRs in predicting END in BAD patients.ROC curve was plotted to assess the predictive value of the four miRs alone or combined together for END.Results The serum levels of miR-130a and miR-210 were significantly higher,while those of miR-141-3p and miR-29a-3p were obviously lower in the deterioration group than the non-deterioration group(P＜0.01).Logistic regression analysis indicated that serum miR-130a,miR-210,miR-141-3p and miR-29a-3p were independent predictors of END in BAD patients(P＜0.05,P＜0.01).ROC curve analysis showed that the AUC value of the four miRs combined together in predicting END in BAD patients was 0.977(95％CI:0.936-0.995),with a sensitivity of 96.43％and a specificity of 90.57％,and the combined detection exhibited better predictive effi-ciency than each indicator alone(P＜0.01).Conclusion Serum miR-130a,miR-210,miR-141-3p and miR-29a-3p have certain value in predicting END in BAD patients,and their combined detec-tion can enhance its predictive efficiency.

Objective To analyze the relationship between serum angiopoietin-like protein 8(ANGPTL8)and semaphorin 3A(Sema 3A)levels and postoperative cerebral vasospasm(CVS)in patients with intracranial aneurysm(IA)rupture.Methods A total of 188 patients with IA rupture receiving surgical treatment in our hospital were prospectively selected during October 2021 and October 2023,and according to whether CVS occurred after surgery,they were classified into a spasm group(75 cases)and a non-spasm group(113 cases).Serum ANGPTL8 and Sema 3A levels were measured after admission.Spearman correlation analysis was performed to assess the correlation of the levels with CVS occurrence.Binary logistic regression analysis was applied to construct a prediction model with serum ANGPTL8 and Sema 3A as variables.ROC curve was plotted to evaluate the predictive value of the levels for postoperative CVS.Results The serum ANGPTL8 level was significantly higher while that of Sema 3A was obviously lower in the spasm group then the non-spasm group(P＜0.01).Binary logistic regression analysis showed that the levels of serum ANGPTL8 and Sema 3A were independent predictors of postoperative CVS in patients with ruptured IA(OR=1.021,95％CI:1.013-1.029,P=0.000;OR=0.980,95％CI:0.967-0.993,P=0.003).ROC curve analysis indicated that the AUC value,sensitivity and speci-ficity of the two indicators combined together in predicting postoperative CVS was 0.939(95％CI:0.894-0.969),89.33％and 89.38％,respectively,with better predictive efficiency than each indicator alone(P＜0.01).Conclusion Serum ANGPTL8 and Sema 3A levels are closely associat-ed with postoperative CVS in patients with IA rupture,and they can be used as effective indicators for early prediction of postoperative CVS.
