Abstract:Objective ?To investigate the correlation between oxidative stress and inflammatory response in the acute phase of brain stem hemorrhage. Methods ?46 patients with brain stem hemorrhage admitted to our hospital from October 2015 to October 2018 were enrolled. According to the guidelines for diagnosis and treatment of cerebral hemorrhage in China, they were divided into death group (25 cases) and survival group (21 cases). Comparison of two groups of aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine (CR), urea nitrogen (BUN), white blood cell count (WBC), procalcitonin (PCT), interleukin 6 ( IL-6), blood lactate, neutrophil count, sodium ion (Na), potassium ion (K), calcium ion (Ca), lactate dehydrogenase (LDH), creatine kinase isoenzyme (CK-MB ), the amount of brain stem bleeding, analysis of the correlation between oxidative stress and inflammatory response after brain stem hemorrhage. Results ?There were no significant differences in CR, BUN, PCT, Na, K, Ca, LDH, CK-MB, and brain stem bleeding between the two groups (P>0.05). AST, ALT, WBC, and neutrophil counts in the two groups. Compared with IL-6, the difference was statistically significant (P<0.05). Spearman correlation analysis showed that WBC, neutrophil count, blood lactate, IL-6, AST, ALT were positively correlated with oxidative stress after brain stem hemorrhage (P<0.05). Multivariate linear logistic regression showed that WBC, neutrophil count, blood lactate level, and IL-6 were independent risk factors for oxidative stress after brain stem hemorrhage.Conclusion ?WBC, neutrophil count, blood lactate level and IL-6 are independent risk factors for oxidative stress after brain stem hemorrhage. They can be used for early detection and intervention of emergency treatment of brain stem hemorrhage, thus improving the success rate of emergency treatment of brain stem hemorrhage. To further reduce mortality and disability.
腦出血后血腫周圍區(qū)域存有大量浸潤性巨噬細(xì)胞,增加心臟和血清中ICAM-1、MCP-1、IL-1的表達(dá),同時(shí)增加了腦出血后炎癥細(xì)胞(白細(xì)胞和巨噬細(xì)胞)向心臟的浸潤,增加心臟組織炎癥因子的表達(dá),但腦干出血相關(guān)炎性反應(yīng)報(bào)道甚少[12]。Wei L等[13]對腦出血后小鼠的腦-心相互作用研究發(fā)現(xiàn),來自受損心肌的炎癥因子與腦組織產(chǎn)生的炎癥因子有協(xié)同作用,在小鼠沒有原發(fā)性心臟病的情況下,腦出血增加了心臟組織中心臟氧化應(yīng)激和炎癥因子的表達(dá),誘導(dǎo)小鼠出現(xiàn)明顯的進(jìn)行性心功能障礙,并伴有心臟纖維化、心肌細(xì)胞肥大和凋亡的增加,證明腦出血可誘導(dǎo)進(jìn)行性心臟缺血。Okamoto K等[14]報(bào)道1例長期反復(fù)腦出血患者腦橋和中腦內(nèi)可見大量AT8免疫反應(yīng)神經(jīng)元和突起,提示氧化應(yīng)激可能加速腦干磷酸化tau蛋白的積累。
本研究中兩組AST、ALT比較,差異有統(tǒng)計(jì)學(xué)意義(P<0.05),說明神經(jīng)系統(tǒng)和免疫系統(tǒng)相互影響,但腦干出血患者心肌損傷表現(xiàn)(LDH、CK-MB)未見明顯差異,可能與腦干出血早期/超早期氧化應(yīng)激損傷尚未波及心血管系統(tǒng)有關(guān),相關(guān)機(jī)制尚待進(jìn)一步研究。
綜上所述,WBC、中性粒細(xì)胞計(jì)數(shù)、血乳酸水平、IL-6是腦干出血后氧化應(yīng)激的獨(dú)立危險(xiǎn)因素,可用于腦干出血急診的早期發(fā)現(xiàn)和干預(yù),從而提高腦干出血急診救治成功率,進(jìn)一步降低死亡率和致殘率。
