目的 预测血必净注射液抗急性肺损伤主要活性成分的作用靶点,探索其“多成分-多靶点-多通路”的复杂网络调节机制。方法 针对血必净注射液中38个主要活性成分,利用反向分子对接技术预测活性成分的作用靶点,并与通过文献挖掘及多种数据库检索得到的急性肺损伤疾病相关靶点进行比对;采用Cytoscape软件构建蛋白互作网络并进行拓扑分析,筛选血必净注射液抗急性肺损伤的关键靶点,借助DAVID数据库对得到的关键靶点进行GO富集分析和KEGG通路注释分析。结果 网络分析结果显示,血必净注射液中38个化合物直接或间接作用于143个关键靶点,共涉及71个生物学过程、29种细胞组分、40种分子功能及25条KEGG通路(P < 0.05,FDR < 0.05),说明血必净注射液主要通过对基因调控、蛋白合成、炎症反应等过程的调节和丝裂原活化蛋白激酶(MAPK)、磷脂酰肌醇3-激酶/蛋白激酶B(PI3K/Akt)等信号通路的干预发挥抗急性肺损伤作用。结论 血必净注射液发挥抗急性肺损伤的作用体现了中药多成分、多靶点、多途径的协同作用特点,为深入阐明血必净注射液治疗急性肺损伤的作用机制提供了重要的科学依据。

Objective To predict the action targets of anti-acute lung injury active ingredients of Xuebijing Injection, and investigate the "multi-components, multi-targets, and multi-pathways" mechanism. Methods Reverse molecular docking was used to forecast its targets of 38 main active components of Xuebijing Injection. The relevant targets of acute lung injury were searched through literature mining and multiple databases and compared with the predicted component targets. The protein interaction network was constructed by Cytoscape software, and topological analysis was performed to screen the key targets of anti-acute lung injury of Xuebijing Injection. And GO enrichment analysis and KEGG analysis were carried out on the key targets through DAVID database. Results The network analysis indicated that 38 active ingredients affected 143 key target proteins directly or indirectly, involved in 71 biological processes, 29 cellular components, 40 molecular function, and 25 KEGG pathways. These active compounds might participate in regulating the processes of gene, protein, external stimulus, and interfering the mitogen-activated protein kinase (MAPK), phosphatidyl inositol 3-kinase (PI3K)-Akt, and other signaling pathways to play a role in resisting to acute lung injury. Conclusion The anti-acute lung injury effect of Xuebijing Injection showed the characteristics of traditional Chinese medicine in multi-components, multi-targets, and multi-pathways. This research provides a scientific basis for elucidation of the anti-acute lung injury pharmacological mechanism of Xuebijing Injection.
