Project description:Poor prognosis for acute cerebral infarction (ACI) was suggested to be predicted using the high expression of some novel molecular markers, for example long non-coding RNAs (lncRNAs). Differentially expressed lncRNAs in peripheral whole blood from the ACI patients and healthy volunteers(HVT) were identified using microarray and further verified by qRT-PCR. The clinical outcome evaluated by 3-month modified Rankin Score (mRS), stroke stratification classified by OCSP criteria, and the expression characteristics of specific lncRNAs were analyzed in ACI patients. Among 5686 differentially expressed lncRNAs screened out by the microarray, nine were verified by qRT-PCR. Particularly, the expression of NR_120420 and lnc-GCH1-2:3 in the ACI group were significantly higher than the HVT group. ROC analysis showed that the sensitivity and specificity of NR_120420 were 85.7% and 84.6% in patients with total anterior circulation infarction (TACI) respectively(area under curve，AUC=0.861), while the sensitivity and specificity of lnc-GCH1-2:3 were 85.7% and 82.1% in patients with TACI respectively(AUC=0.802). Multivariate logistic regression showed that NR_120420 was a significantly independent diagnostic factor for ACI. The elevated expression levels of NR_120420 and lnc-GCH1-2:3 were associated with the TACI stroke classification and the poor prognosis of ACI. Our study clearly illustrated that the elevated expression levels of circulating NR_120420 and lnc-GCH1-2:3 could predict the TACI stroke classification with high sensitivity and specificity and the poor prognosis of patients with ACI.

Project description:Indices for diagnosis of hyperacute cerebral infarction (HACI) and prediction of prognosis are essential for timely and appropriate management. MicroRNAs(miRNAs) regulating gene expression following stroke have potential use as prognostic markers of HACI. Here, we explored whether concentrations of circulating miRNAs could be correlated with clinical outcomes and thus form the basis of a system of stroke stratification. Plasma samples from patients with HACI (n = 7) and age-matched healthy volunteers (HVT, n = 4) were screened by microarray to find differentially expressed miRNAs, which were further verified by quantitative reverse transcription polymerase chain reaction(qRT-PCR) (HACI:HVT = 33:23). The target genes of the miRNAs with verified differential expression were investigated by GO and KEEG analysis. Using the TOAST (OCSP) criteria and the 3-month modified Rankin Score(mRS), relationships between the expression patterns of specific miRNAs, stroke stratification，and clinical prognosis were determined. The microarray analysis revealed 12 differentially expressed miRNAs. Among seven selected miRNAs verified with qRT-PCR, miR-16 expression in the HACI group was the most significantly different from the HVT group (P < 0.01). Bioinformatics analysis showed that the potential target genes of miR-16 were mainly involved in programmed cell death and the p53 signaling pathways. Receiver operating characteristic(ROC) analysis showed that the area under curve(AUC) of miR-16 was 0.775 (sensitivity 69.7% and specificity 87%) and 0.952 (sensitivity 100% and specificity 91.3%) in overall patients and patients with large artery atherosclerosis (LAAS), respectively. Elevated miR-16 expression was associated with the stroke subtype of LAAS, total anterior circulation infarction, partial anterior circulation infarction, and poor prognosis (P < 0.05). A diagnostic method based on rapid measurement of plasma miR-16 has potential to identify hyperacute cerebral infarction with LAAS with high sensitivity and specificity, which would inform and improve early treatment decisions and disease management.

Project description:Lacunar infarction (LACI), a difficult to diagnose, subtype of acute ischemic stroke affects around 25% of all ischemic stroke cases. Despite having an excellent recovery during acute phase, certain LACI patients have poor mid- to long-term prognosis due to the recurrence of vascular events or dementia. The existing clinical protocols are unable to predict the prognosis of LACI patients. Blood-based biomarkers maybe useful as complementary prognostic and research tools.

Project description:Purpose Acute ischemic stroke is characterised by high disability rate and high recurrence rate, which poses a great threat to the life and health of the nation. CHZF Capsule was developed by Ren Jixue, a national medical master, and clinical studies have confirmed that it not only promotes the recovery of neurological function in patients with cerebral infarction, reduces the disability rate, but also improves the long-term prognosis, but the target of its action is still unclear. This study reveals for the first time the target of action of CHZF capsule in the treatment of acute ischaemic stroke, which provides a direction for the study of traditional Chinese medicine compound to prevent and treat acute cerebral infarction. METHODS The aim of this study was to screen the unique differential proteins in patients with acute cerebral infarction by applying CHZF capsule. Twenty patients with acute ischemic stroke were included and classified into CHZ and DZZ according to whether CHZF capsule was applied or not.

Project description:Monocytes play a central role in the inflammatory response that follows acute myocardial infarction (MI). In order to study phenotypic adaptation of this cell type, we investigated patterns of monocyte gene expression in circulating monocytes at various stages of MI. Circulating monocytes were isolated from venous blood of MI patients at three time points: t1: within 6 hours after onset of chest pain (acute phase), t2: 3 days after MI (subacute phase), t3: 90 days after MI (chronic phase). For comparison, we studied a control group (n=21, data to be submitted later) with stable coronary artery disease. Using this transcriptomic analysis, we aimed to provide a more comprehensive reference of monocyte biology following acute MI and to aid in the identification of novel pathways and genes influencing the course of MI.
