代谢物组学和细胞因子谱学探讨颅内动脉瘤破裂的危险因素研究 Risk Factors for Intracranial Aneurysm Rupture Using Metabolomics and Cytokine Profiling Analysis
Abstract
目的 探讨血清与颅内动脉瘤组织中与动脉瘤破裂相关的代谢物和细胞因子标志物。 方法 前瞻性纳入2020年1月—2022年1月行单发颅内动脉瘤手术治疗的患者。收集患者的动脉瘤组织和血清样本。根据患者入院时是否发生动脉瘤破裂分为破裂颅内动脉瘤和未破裂颅内动脉瘤组。采用靶向代谢组学的方法检测动脉瘤组织和血清中的代谢物，采用46种细胞因子芯片的方法检测细胞因子。运用Spearman相关性分析血清与颅内动脉瘤组织中与动脉瘤破裂相关的代谢物和细胞因子。运用ROC检测代谢物和细胞因子能否区分破裂和未破裂的颅内动脉瘤。运用logistic回归分析探讨和颅内动脉瘤破裂相关的因素。 结果 研究纳入25例破裂和31例未破裂颅内动脉瘤患者。非靶向代谢组学和细胞因子谱学分析显示，在破裂和未破裂颅内动脉瘤组织之间，有43个代谢物和5个细胞因子的差异具有统计学意义（均P0.7）。多因素logistic回归分析显示，血清油酸水平（OR 0.74，95%CI 0.60～0.87，P=0.001）是颅内动脉瘤破裂的独立相关因素。 结论 相比于未破裂颅内动脉瘤，血清和颅内动脉瘤组织中油酸和IL-1ra的表达水平在破裂颅内动脉瘤中显著降低，而花生四烯酸、IL-1β、MCP-1和TNF-α的表达水平在破裂颅内动脉瘤中显著升高。血清油酸降低是颅内动脉瘤破裂的独立危险因素。 Objectives To investigate the metabolite and cytokine biomarkers related to intracranial aneurysm rupture using the metabolomics and cytokine profiling analysis. Methods The patients undergoing surgery for single intracranial aneurysm from January 2020 to January 2022 were prospectively enrolled in this study. The aneurysm tissues and serum samples of patients were collected. According to intracranial aneurysm state at admission, all patients were divided into the ruptured aneurysm group and unruptured aneurysm group. The targeted metabolomics was used to detect the abnormal metabolites in aneurysm tissue and serum, and the 46-cytokine profiling analysis was used to detect the abnormal cytokines. The Spearman correlation analysis was used to analyze the correlation of these metabolites and cytokines with aneurysm rupture in aneurysm tissues and serum. Receiver operating characteristic (ROC) curve was used to evaluate the clinical value of these risk factors for aneurysm rupture, and multivariate logistic regression analysis was used to determine the risk factors for aneurysm rupture. Results This study included 25 cases with ruptured aneurysm and 31 cases of unruptured aneurysm. The targeted metabolomics and cytokine profiling analysis found 43 metabolites and 5 cytokines related to aneurysm rupture (all P0.7) . Multivariate logistic regression analysis showed that serum oleic acid (OR 0.74, 95% CI 0.60-0.87, P=0.001) was an independent risk factor for aneurysm rupture. Conclusions The levels of oleic acid and IL-1 receptor antagonist decreased, and the levels of arachnoid acid, IL-1β, MCP-1 and TNF-α increased in serum and aneurysm tissue in patients with ruptured intracranial aneurysm, compared to that in patients with unruptured aneurysm. The decreased level of serum oleic acid was an independent risk factor for intracranial aneurysm rupture.
