Xingnaojing is widely used in China, but there is lack of sufficient and reasonable explanation of its intervention effects for acute ischemic stroke currently. In order to further clarify the main pharmacodynamic substances of Xingnaojing in the treatment of acute ischemic stroke, this study intends to carry out a non-randomized, open-label, controlled clinical trial. The primary hypothesis is that , compared with the control group, Xingnaojing will produce serial changes in plasma metabolites at baseline (pre-dose) and 7 days, as well as urine metabolites at baseline (pre-dose), 6 days, 7 days and 8 days. The serial changes may be the potential support to explain the intervention effect of Xingnaojing. All participants will have a National Institutes of Health Stroke Scale(NIHSS)entry score of 4-25. Participants who have planned or already received the intravenous thrombolysis or endovascular treatment will be excluded.
The main purposes of this trial are to analyze the pharmacodynamic substances and the effects of Xingnaojing for mild-to-severe acute ischemic stroke.
