Abstract: Objective  This study aims to investigate the relationship of peripheral yes-associated protein (YAP) level in patients with acute ischemic stroke (AIS) with prognostic influencing factors and inflammatory indicators. Methods  AIS patients admitted to Xuanwu Hospital of Capital Medical University from November 2018 to May 2019 were enrolled in this study. Expression levels of YAP and inflammatory markers in plasma were detected, and the clinical data and 3-month prognostic data of the patients were collected by experienced neurologists. According to the 3-month modified Rankin Scale (mRS) score, the patients were divided into good outcome group (mRS≤2, n=92) and poor outcome group (mRS>2, n=67). Multivariate Logistic regression analysis was used to identify independent risk factors related to AIS prognosis. Furthermore, Spearman correlation analysis and partial correlation analysis were conducted to explore the relationship of YAP concentration with these prognostic influencing factors and inflammatory indicators. Results Compared with the good outcome group, the poor outcome group exhibited significantly higher white blood cell counts, neutrophil counts, and neutrophil-lymphocyte ratios (NLR), along with significantly lower lymphocyte counts (P<0.05). Logistic regression results indicated that older age (OR=1.04, P=0.013), diabetes mellitus (OR=3.87, P=0.004), and higher admission National Institutes of Health Stroke Scale (NIHSS) scores (OR=1.36, P<0.001) are risk factors for prognosis. Correlation analysis showed that plasma YAP levels were positively correlated with lymphocyte counts (r=0.22, P=0.006), IL-1β (r=0.418, P<0.001), IL-2 (r=0.310, P<0.001), IL-5 (r=0.417, P<0.001), and IL-10 (r=0.189, P=0.017), while being negatively correlated with neutrophil counts (r=-0.17, P=0.027), NLR (r=-0.24, P=0.002), IL-2R (r=-0.259, P<0.001), IL-16 (r=-0.334, P<0.001), and (hepatocyte growth factor, HGF) (r=-0.317, P<0.001). Partial correlation analysis indicated that the correlation between YAP protein levels and IL-2, IL-16, and HGF was not affected by other variables (P<0.05). Conclusions  There is a significant correlation between plasma YAP levels and various inflammatory indicators, suggesting that YAP may be involved in the regulation of inflammatory response after stroke.
