Circulating circRNA in Acute Ischemic Stroke

Recruiting

• Conditions: Acute Ischemic Stroke
• Interventions: Genetic: Quantitative Real-time polymerase chain reaction

• Registration Number: NCT05098340
• Lead Sponsor: The Affiliated Hospital of Xuzhou Medical University

Brief Summary

CRAST is to analyze the expression pattern of circular RNA (circRNA) by bioinformatics analysis in patients with acute ischemic stroke and healthy control. The candidate circRNA will be verified as biomarkers for the detection and prognosis of acute ischemic stroke.

Detailed Description

Circular RNAs have been highlighted to be involved in the pathological process of ischemic stroke (IS). The purpose of this protocol will investigate the expression pattern of circular RNA (circRNA) by bioinformatics analysis in patients with acute ischemic stroke and healthy control. The candidate circRNA will be verified as biomarkers for the detection and prognosis of acute ischemic stroke. Distinctive expression patterns of circRNA will be identified by individual quantitative real time polymerase chain reaction (qRT-PCR). A diagnostic or predictive model will be established using logistic regression. The panel of these altered circRNAs may be associated with acute IS and could serve as a novel diagnostic or predictive method.

Arm && Interventions

Group	Intervention	Description
AIS group	Quantitative Real-time polymerase chain reaction	This group includes patients with acute ischemic stroke (AIS).
HC group	Quantitative Real-time polymerase chain reaction	This group includes healthy controls (HC).

Primary Outcome Measures

Name	Time	Method
Differential expression pattern of circRNA	90 days	Differential expression pattern of circular RNA (circRNA) will be compared between AIS group and HC group, thus candidate circRNA will be verified as biomarkers for the detection and prognosis of AIS.

Secondary Outcome Measures

Name	Time	Method
Prognostic value of circRNA in acute ischemic stroke	90 days	The prognosis of AIS patients will be analyzed between differential expressed candidate circRNA after they have completed the systematic therapy.
Dynamic changes of circRNA during the follow-up period	90 days	Dynamic changes of circRNA will be explored before and after endovascular therapy
Correlation of circRNA and inflammatory factors in acute ischemic stroke	7 days	Correlation of circRNA and inflammatory factors on admission will be explored in acute ischemic stroke.
Correlation of circRNA and stroke-associated infection	30 days	Correlation of circRNA and stroke-associated infection will be explored in acute ischemic stroke.
