Abstract:
Objective To investigate the effects of serum insulin-like growth factor 2(IGF2),leucine-rich repeat and fibronectin type Ⅲ domain containing 5(LRFN5)levels on neurological rehabilitation in patients with ischemic stroke(IS).Methods A total of 103 patients with IS who were treated in Shiyan Taihe Hospi-tal from October 2022 to March 2024 were selected as the study group.According to the modified Rankin scale(mRS)score,they were divided into 46 cases in the poor rehabilitation group and 57 cases in the good rehabili-tation group.Another 61 healthy individuals who underwent physical examinations in the hospital during the same period were selected as the control group.The levels of serum IGF2 and LRFN5 were detected by en-zyme-linked immunosorbent assay.Pearson and Spearman correlation analyses were used to analyze the corre-lations between the levels of serum IGF2 and LRFN5 in the poor rehabilitation group and the related indica-tors of neurological function.Logistic regression was used to analyze the influencing factors of poor neurologi-cal rehabilitation in patients with IS,and the receiver operating characteristic curve was plotted to analyze the diagnostic value of serum IGF2 and LRFN5 levels for poor neurological rehabilitation in patients with IS.Re-sults The serum IGF2 level in the study group was significantly lower than that in the control group,and the LRFN5 level was significantly higher than that in the control group.The difference was statistically significant(P<0.05).The scores of the National Institutes of Health Stroke Scale(NIHSS)at admission,the 90-day mRS score,the maximum diameter of the cerebral infarction lesion and the LRFN5 level in the poor rehabilita-tion group were significantly higher than those in the good rehabilitation group,and the IGF2 level was signifi-cantly lower than that in the good rehabilitation group.The differences were statistically significant(P<0.05).The level of serum IGF2 was negatively correlated with the NIHSS score at admission,the 90-day mRS score and the maximum diameter of cerebral infarction lesions.The level of LRFN5 was positively correlated with the NIHSS score at admission,the 90-day mRS score and the maximum diameter of cerebral infarction lesions.The level of IGF2 was negatively correlated with the level of LRFN5(P<0.05).The results of Logis-tic regression analysis showed that the 90-day mRS score and LRFN5 level were risk factors for poor neuro-logical function rehabilitation in patients with IS,and the IGF2 level was a protective factor for poor neurologi-cal function rehabilitation in patients with IS(P<0.05).The area under the curve(AUC)of the combined diagnosis of serum IGF2 and LRFN5 was 0.943(95%CI:0.902-0.984),which was significantly higher than AUC of the diagnosis by a single indicator(Zcombined with the two-IGF2=2.039,P=0.041;Zcombined with the two-LRFN5=2.139,P=0.032).Conclusion The IS patients have a significant reduction in serum IGF2 level and a signifi-cant increase in serum LRFN5 level,which are closely related to their neurological function recovery.The combination of IGF2 and LRFN5 has a certain diagnostic value for neurological function recovery in IS pa-tients.
