摘要: 采用网络药理学方法,预测苹果治疗溶血所致高胆红素血症的可能活性成分、潜在靶点及其富集的通路和作用过程,构建苹果的“疾病-通路-活性成分-靶标”;采用Autodock软件对关键活性成分和潜在靶标进行分子对接,验证网络分析结果的可靠性;并构建溶血所致高胆红素血症大鼠实验模型,探讨苹果对溶血性所致高胆红素血症的作用。结果表明,搜集整理符合胃肠吸收度高、类药性优的苹果活性成分有17 个,其中槲皮素、2α-羟基熊果酸、β-谷甾醇、根皮素、表儿茶素对治疗溶血所致高胆红素血症有重要的贡献。网络中度值排名前5的靶标丝氨酸/苏氨酸蛋白激酶1、血管内皮生长因子A、表皮生长因子受体、酪氨酸激酶、信号传导及转录激活因子3通过胆汁分泌、缺氧诱导因子信号通路、肿瘤坏死因子(tumor necrosis factor,TNF)信号通路、核因子-κB信号通路等发挥治疗作用;对网络筛选的主要活性成分和核心靶标进行分子对接,结果显示苹果筛选的活性成分和获得的治疗溶血所致高胆红素血症潜在靶标有较强的亲和能力,网络分析结果可靠;动物实验结果显示,与空白组比较,模型组血液中血红蛋白(hemoglobin,HB)的水平明显降低,总胆红素(total bilirubin,TB)、间接胆红素(indirect bilirubin,IB)、谷丙转氨酶(alanine transaminase,ALT)、谷草转氨酶(aspartate transaminase,AST)、TNF-α、白细胞介素-6(interleukin-6,IL-6)水平明显升高(P<0.01);与模型组相比,苹果醇提物干预组、阳性对照组的HB水平升高,TB、IB、ALT、AST、TNF-α、IL-6水平明显下降(P<0.05或P<0.01)。综上,苹果可以减轻溶血所致高胆红素血症,本研究可为新生儿黄疸无损伤疗法的研究奠定基础。

Abstract: A network pharmacological approach was used to predict active ingredients in apples that may have therapeutic effects on hemolysis-induced hyperbilirubinemia and their potential targets, enrichment pathways and action process and to construct adisease-pathway-active component-target network for apples. Autodock software was used to perform molecular docking of key active ingredients and potential targets to verify the reliability of the network analysis results. Furthermore, the effect of apple alcohol extract (AE) on hemolysis-induced hyperbilirubinemia in rats was explored. The results showed that 17 active ingredients of apples with high gastrointestinal absorption and excellent drug-like properties were selected, among which, quercetin, 2α-hydroxyl-ursolic acid, β-sitosterol, phloretin and epicatechin could make important contribution to the treatment of hemolysis-induced hyperbilirubinemia. The top 5 targets in terms of moderate values in the network, including the serine/threonine protein kinase (Akt1), vascular endothelial growth factor A (VEGFA), epidermal growth factor receptor (EGFR), the tyrosine kinase (SRC), and signal transducer and activator of transcription 3 (STAT3) could exert therapeutic effects through the bile secretion pathway, the hypoxia inducible factor (HIF)-1 signaling pathway, the tumor necrosis factor (TNF) signaling pathway and the nuclear factor-kappa B (NF-κB) signaling pathway. Molecular docking was performed on the major active ingredients and the core targets selected by the network, and the results showed a strong affinity between the active ingredients and the potential targets with reliable results from the network analysis. The animal experimental results indicated that compared with the blank control group, the model group had a significant decrease in hemoglobin (HB) levels in the blood and a significant increase in the levels of total bilirubin (TB), indirect bilirubin (IB), alanine transaminase (ALT), aspartate transaminase (AST), TNF-α, and interleukin-6 (IL-6) (P < 0.01). Compared with the model group, HB levels increased and while the levels of TB, IB, ALT, AST, TNF-α and IL-6 significantly decreased in the AE intervention and positive control groups (P < 0.05 or P < 0.01). In summary, apples reduce hemolysis-induced hyperbilirubinemia, which will provide a basis for research on non-invasive therapy for neonatal jaundice.
