ObjectiveTo explore the efficacy-driving mechanism of Danhong injection （DHI） in the treatment of stable angina pectoris （SAP） based on the composition-activity relationship of target modules and clarify the pharmacological effects of DHI. MethodAccording to the angina frequency （AF） in the Seattle Angina Questionnaire （SAQ） that was obtained in the previous clinical trial， the patients before and after DHI treatment were grouped based on efficacy. The transcriptomic data of the patients before treatment and in the best efficacy group 30 days post-treatment were selected as the data source， and then weighted gene co-expression network analysis （WGCNA） was employed to construct the co-expression network. Relevant modules in the network were identified and associated with clinical features. In addition， the On-modules （Z value below 0） were identified by Zsummary. The topological indicators such as density， centrality， and clustering coefficient were adopted to explore the dynamics of DHI efficacy at the network level and module level， respectively. In addition， the driver genes were screened by the personalized network control （PNC） algorithm. Finally， rat H9C2 cells were used to establish the model of hypoxia/reoxygenation （H/R）， which was used to confirm the potential therapeutic target of DHI for SAP and provide a scientific basis for revealing the therapeutic mechanism of DHI. ResultWe identified 19 modules in the best efficacy group of DHI for SAP， and the comparison between day 0 and day 30 revealed 12 On-modules. The changes of network topological indicators at the network and module levels confirmed the correlation between the best efficacy of DHI treatment and topological dynamics. Finally， the driver genes， Klotho and fibroblast growth factor 22 （FGF22）， in DHI treatment of SAP were verified by the H9C2 cell model of H/R. ConclusionBased on clinical transcriptome data， this study determined the composition-activity relationship of target modules of DHI for SAP， which provided a scientific basis for deciphering the efficacy-driven mechanism of DHI for SAP.

Objective:To evaluate the effect of imatinib on the endotoxemia-induced acute lung injury in mice.Methods:Sixty SPF male, 8-12 weeks, C57BL/6 mice were randomly (random) divided into 4 groups ( n=15 each): control group (group C), imatinib group (groupⅠ), endotoxemia group (group LPS) and imatinib + endotoxemia group (group I+LPS). The endotoxemia model of acute lung injury was established. After 24 hours, the mice were sacrificed. The pathological changes of lung tissues were evaluated, the lung injury scores were calculated, and the wet/dry ratios of lung tissues were measured. ELISA was used to detect the levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in serum. Detection kits were used to analyze the levels of malondialdehyde (MDA), glutathione (GSH), catalase (CAT), superoxide dismutase (SOD) and the ratio of reduced glutathione to oxidized glutathione (GSH/GSSG) in lung tissues; The expression levels of phosphorylated nuclear factor-kappa B (p-NF-κB), nuclear factor-erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) in lung tissues were analyzed by western blotting. Results:Compared with the group C, the wet/dry (W/D) ratio of lungs [(3.47±0.41) vs. (5.58±0.47)], lung injury scores [(1.25±0.89) vs. (10.25±1.75)], and the levels of TNF-α and IL-6 in serum increased in the group LPS ( P<0.05). The levels of SOD, CAT, GSH and GSH/GSSG decreased, the level of MDA increased, and the expression of p-NF-κB, Nrf2 and HO-1 protein up-regulated ( P<0.05). Compared with the LPS group, the W/D ratio of lungs [(5.58±0.47) vs.(4.62±0.38)] and lung injury scores [(10.25±1.75) vs. (7.00±1.31)] in the I+LPS group decreased ( P<0.05), and the levels of TNF-α and IL-6 in the serum decreased ( P<0.05). In lung tissues, the levels of SOD, CAT, GSH and GSH/GSSG increased (all P<0.05), the level of MDA decreased (all P<0.05), the expression of p-NF-κB protein decreased, and the expression of Nrf2 and HO-1 protein increased ( P<0.05). Conclusions:Imatinib improves sepsis-induced acute lung injury in mice, and the mechanism of actions behind may be related to the inhibition of oxidative stress.
