LncRNA HULC in plasma samples from 215 first episode AIS patients and 215 age/gender-matched non-AIS controls was detected by reverse transcriptional-quantitative polymerase chain reaction (RT-qPCR). Then, in AIS patients, interleukin-6 and intercellular adhesion molecule 1 (ICAM1), as well as microRNA (miR) target of lncRNA HUCL (miR-9 and miR-195), were detected by enzyme-linked immunosorbent assay and RT-qPCR, respectively. Disease severity was assessed by National Institution of Health stroke scale (NIHSS) score. AIS recurrence or death was recorded, and recurrence-free survival (RFS) was calculated. LncRNA HULC was increased in AIS patients compared to non-AIS controls (P<.001), and receiver operating characteristic curve showed that it was correlated with increased AIS risk (area under curve 0.876, 95% confidence interval 0.843-0.908). Meanwhile, lncRNA HULC was positively correlated with NIHSS score (P<.001, r=.456), interleukin-6 (P<.001, r=.275) and ICAM1 (P<.001, r=.383), whereas negatively correlated with miR-9 (P<.001, r=-.438) but not miR-195 (P=.205, r=-.087) in AIS patients. Additionally, miR-9 was negatively correlated with NIHSS score (P<.001, r=-.335), interleukin-6 (P=.001, r=-.231), and ICAM1 (P<.001, r=-.280), while miR-195 was only negatively associated with NIHSS score (P=.041, r=-.139) in AIS patients. Moreover, lncRNA HULC high expression predicted worse RFS (P=.013) in AIS patients. LncRNA HULC is correlated with higher AIS risk, increased disease severity and worse prognosis in AIS patients. Meanwhile, it associates with higher IL-6, elevated ICAM1, and lower miR-9 AIS patients.

Meanwhile, it associates with higher IL-6, elevated ICAM1, and lower miR-9 AIS patients. T
