Objective To analyze the correlation of inflammatory markers C-reactive proten(CRP),serum amyloid protein A(SAA),interleukin-6(IL-6)levels and subjective sleep characteristics in patients with first-episode acute cerebral infarction.Methods A total of 113 patients with first-episode cerebral infarction admitted to the Department of Neurology,the People's Hospital of Fuyang from March 2022 to April 2023 were prospectively and continuously selected as subjects.According to the Pittsburgh sleep quality index(PSQI),they were divided into insomnia group(PSQI＞7 points)and non-insomnia group(PSQI ≤7 points).General demo-graphic data and differences in CRP,SAA,IL-6 levels,Hamilton anxiety scale(HAMA)and Hamilton depression scale(HAMD)scores were compared between the two groups.Partial correlation analysis was used to analyze the correlation between three serum markers and PSQI effect factors.Results There were no significant differences in age,gender,baseline NIHSS score and mRS score between the two groups(P＞0.05).HAMD scores(z=-3.993,P＜0.001),HAMA scores(z=-3.806,P＜0.001),CRP,IL-6,SAA(P＜0.001)in insomnia group were significantly higher than those in non-insomnia group.The history of hyperlipidemia between the two groups was statistically significant(z=5.913,P=0.015).Multivariate Logisitic regression analysis showed that CRP(OR=1.55,P＜0.01),HAMD scores,HAMA scores and hyperlipidemia were independent risk factors for chronic insomnia in patients with first-episode cerebral infarction,and HAMD scores had a greater effect than HAMA scores(OR:1.10 vs 1.04).Partial correlation analysis showed that IL-6 and CRP levels were significantly correlated with the total score of PSQI(P＜0.05),while SAA was not significantly correla-ted with the total score of PSQI(P＞0.05).IL-6 level was positively correlated with sleep quality(r=0.231)sleep efficiency(r=0.322)and sleep duration(r=0.221).SAA level was positively correlated with sleep efficiency(r=0.242),while CRP level was posi-tively correlated with sleep latency(r=0.194),sleep duration(r=0.247)and sleep efficiency(r=0.225).Conclusion The inflam-matory markers CRP,IL-6 and SAA levels were elevated in the patients with first-episode cerebral infarction accompanied by insomnia,which were correlated with the severity of insomnia.The correlation between CRP and IL-6 levels and sleep characteristics was consistent with each other.

Objective: To explore the hemorrhagic transformation(HT) and its effect on prognosis in patients with acute ischemic stroke(AIS) after mechanical thrombectomy(MT). Methods: A total of 114 patients with AIS received MT were enrolled. The modified Rankin Scale was used to evaluate the clinical outcome at 90 days of onset(0-2 points were good prognosis; 3-6 points were poor prognosis). The patients were divided into HT group(n=25) and non-HT group(n=89) according to their HT conditions. Binomial Logistic regression analysis was performed to determine the vascular risk factors of HT after MT and the effect of HT on prognosis. Results: Among 114 patients, there were 25 cases of HT and 89 cases of non HT. The proportion of patients with diabetes in HT group was significantly higher than that in non-HT group. The NIHSS score of HT group at discharge was significantly higher than that in non-HT group. The proportion with good prognosis at 90 days in HT group was significantly lower than that in non-HT group(allP<0.05). Binomial Logistic regression analysis showed that diabetes, high levels of cholesterol and smoking were the major vascular risk factors for HT after thrombectomy(allP<0.05). HT was an important factor affecting the poor prognosis after arterial thrombectomy(P=0.026). Conclusion Diabetes, high levels of cholesterol and smoking are the main risk factors of HT after MT for AIS. HT is an independent risk factor for poor prognosis after MT.
