Different Treatment Strategies on Prognosis of Acute Ischemic Stroke(AISDTS)

Study Overview
=================
Brief Summary
-----------------
AISDTS is a prospective registry study, in which clinical information, examination and imaging data of patients with acute ischemic stroke receiving different treatment strategies were collected, grouped and statistically analyzed, and corresponding clinical prediction models were constructed to explore the role of clinical biological indicators in the occurrence and development of stroke.

Detailed Description
-----------------
To study which variable or variables (various clinical biological indicators) affect the prognosis of ischemic stroke patients; To study the differences in variables (various clinical evaluations, biological indicators, etc.) among patients receiving different treatment strategies (including thrombolysis group, thrombectomy group, stent group, chronic occlusion reperfusion group and regular treatment group); To study hemoglobin, mean erythrocyte volume, white blood cell count, neutrophil count, lymphocyte count, monocyte count, IL-2, IL-4, IL-6, IL-10, IFNγ, TNFα, C-reactive protein, serum iron and iron-related proteins (ferritin, transferrin, fibromodulin, ceruloplasmin), uric acid, amino acid, lipoprotein, homocysteine, vitamin D and other clinical indicators that correlated with acute ischemic stroke patients and different treatment groups were compared; To study the relationship between blood pressure changes at multiple time points from admission to discharge and clinical manifestations and prognosis of stroke patients, and to make comparison between groups; To study the relationship between ischemic stroke and other variables (clinical assessment, biological, genetic and neuroimaging) in different pathological types; To study the correlation between neuroimaging indicators and clinical evaluation, biomolecular, genetic and other variables; DNA and RNA were extracted from peripheral blood samples of patients with acute stroke for genetic related studies to explore the genetic susceptibility of young stroke and unexplained stroke; To study the role of one-stop multimodal-MRI in the assessment and diagnosis of patients with acute ischemic stroke; To study the adverse reactions (hemorrhage, embolus shedding, gastrointestinal ulcer) and stroke-related complications under different treatment strategies (including thrombolysis group, thrombectomy group, stent group, chronic occlusion reperfusion group and regular treatment group); To study the effect of Sanbexin® (Edaravone and Dexborneol Concentrated Solution for Injection) on inflammation and the prognosis in ischemic stroke patients.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To assess the changes of prognosis of stroke patients under different treatment strategies | assessed by The Modified Rankin Score (mRS) of stroke patients [mild to wores ranging from 0 to 5, 6 represents death]. | 3 months, 6 months, 12 months or 24 months | 
| To assess the early neurological changes of ischemic stroke | change from baseline National Institute of Health stroke scalescore (NIHSS) [higher scores mean worse conditions]7 days or 14 days | 7 days or 14 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To assess the incidence of recurrent stroke under different treatment strategies | record and analyze the incidence of recurrent stroke from 7 days-24 months | 7 days-24 months | 
| To assess the types and incidence of adverse events of ischemic stroke patients | adverse reactions (hemorrhage, embolus shedding, gastrointestinal ulcer) and stroke-related complications under different treatment strategies | 3 days-24 months | 
| To assess the correlation of RNA/DNA and age factor in acute ischemic stroke | DNA and RNA extracted from peripheral blood samples | 3 months | 
| To assess the therapeutical effects of Edaravone dexborneol on inflammation and prognosis after acute ischemic stroke | The Modified Rankin Score score (mRS) of stroke patients [mild to wores ranging from 0 to 5, 6 represents death]. | 3 months |
