We performed long non-coding RNA (lncRNA) microarray assay to identify lncRNAs with differential expression between patients with intracranial aneurysm (IA) and healthy control individuals to evaluate their potential use as biomarkers of IA. Arraystar Human lncRNA Microarray v3.0 was performed to identify differentially expressed lncRNAs and mRNAs in plasma samples (4 ml). lncRNAs with the most pronounced differential expression were used to select gene markers, and results were validated by quantitative reverse-transcription polymerase chain reaction (qRT-PCR). Plasma levels of TCONS_00000200 (fold change: 2.28) and ENST00000511927 (fold change: 2.50) were significantly higher in IA patients than in healthy individuals (P<0.001), and plasma levels of ENST00000421997 (fold change: 0.45) and ENST00000538202 (fold change: 0.43) were significantly lower in IA patients than in healthy individuals (P<0.001). qRT-PCR confirmed the same trends of up- and down-regulation of these four lncRNAs. A receiver operating characteristic (ROC) curve for TCONS_00000200 showed that the area under the curve (AUC) was 0.963 (95% confidence interval, 0.919-1.000), optimal cut-off point was 0.0081, sensitivity was 90.0%, and specificity was 96.7%. These results indicate that the lncRNA TCONS_00000200 is differentially expressed in the plasma of IA patients and could serve as a biomarker of IA.

BACKGROUND: Depression is a common psychological disorder that severely threatens human health. Its pathology remains unclear, but it has been suggested to be associated with abnormal blood lipid metabolism. OBJECTIVES: This study aimed to explore the changes in blood lipid levels in patients with depression accompanied or not by anxiety, and assess whether adjusting the clinical therapeutic strategy could be based on blood lipid test results, providing a novel insight into depression treatment. METHODS: This was a cross-sectional study. We assessed 60 outpatients and inpatients diagnosed with depression from January 2013 to January 2014 who met the Chinese Classification of Mental Disorders version 3 (CCMD-3) criteria, with Hamilton Rating Scale for Depression (HAMD-24) ≥20. They were grouped into depression with anxiety (n=29) and depression without anxiety (n=31) groups by the Hamilton Anxiety Scale (HAMA). RESULTS: TG levels were higher in the depression with anxiety group compared with patients without anxiety (P=0.045), which was confirmed by multifactorial analysis [P=0.017, OR=4.394, 95% CI (1.303-14.824)]. A negative correlation between anxiety score and HDL levels was observed in patients with depression (r=-0.340, P=0.046). Meanwhile, positive associations were obtained between retardation and LDL levels (r=0.307, P=0.017) as well as age at disease onset and total cholesterol levels (r=0.410, P=0.002). CONCLUSION: TG levels differ in patients with depression accompanied by anxiety compared with those without anxiety.
