摘 要 目的：研究良附丸治疗胃溃疡的作用机制。方法：基于网络药理学，通过检索中药系统药理学技术平台（TCMSP）、Gene-
Cards、OMIM和DisGeNET等数据库，筛选良附丸的活性成分、靶点和胃溃疡相关靶点，并利用Venny 2.1软件筛选良附丸活性成
分与胃溃疡的共同靶点；通过STRING数据库构建良附丸治疗胃溃疡的蛋白互作网络图，并利用Cytoscape 3.7.2软件对该网络进
行拓扑分析；通过DAVID数据库对良附丸的活性成分与胃溃疡的共同靶点进行基因本体（GO）功能和京都基因与基因组百科全
书（KEGG）通路富集分析，并构建良附丸活性成分-胃溃疡靶点-KEGG通路网络图。在动物实验验证中，取小鼠随机分为空白组、
模型组、雷尼替丁组（阳性对照，39 mg/kg）和良附丸低、中、高剂量组（0.78、1.56、3.12 g/kg），分别灌胃相应药物，每天1次，连续7
天。末次给药后，除空白组外，其余各组小鼠灌胃无水乙醇（0.01 mL/g），以复制胃溃疡模型。造模成功后，取小鼠胃组织观察病
变情况，并计算胃溃疡指数；检测小鼠胃组织中TP53、c-Jun、p38丝裂原活化蛋白激酶（p38 MAPK）、蛋白激酶B（Akt）、磷酸化Akt
（p-Akt）和肿瘤坏死因子α（TNF-α）蛋白的表达水平。结果：共筛选出良附丸中的9个活性成分（如异鼠李素、β-谷甾醇、山柰酚等）
和166个共同靶点。良附丸可通过细胞对化学刺激的反应、蛋白质结合、细胞外空间等GO功能，以及癌症信号通路、乙型肝炎、膀
胱癌、胰腺癌、TNF信号通路、前列腺癌等KEGG通路发挥治疗胃溃疡作用。动物实验结果显示，与模型组比较，良附丸能显著降
低小鼠胃组织病变情况和胃溃疡指数，以及 TP53、c-Jun、p38 MAPK、Akt、p-Akt 和 TNF-α蛋白的表达水平（P＜0.05 或 P＜0.01）。
结论：筛选出了良附丸治疗胃溃疡的9个活性成分和166个靶点；良附丸可通过抑制MAPK、NF-κB、TNF和PI3K/Akt等多条通路
等，抑制炎症因子的表达，从而发挥改善胃溃疡的作用。

ABSTRACT OBJECTIVE：To study the mechanism of Liangfu pills in the treatment of gastric ulcer. METHODS：Based on
network pharmacology，the active ingredients，targets and gastric ulcer related targets of Liangfu pill were screened by searching
TCMSP，GeneCards，OMIM and DisGeNET databases，and the common targets of Liangfu pill and gastric ulcer were screened by
Venny 2.1 software. The protein interaction network of Liangfu pill in the treatment of gastric ulcer was constructed by STRING
database. Cytoscape 3.7.2 software was used to construct topological analysis of the network.The function of GO and the enrichment
of KEGG pathway were analyzed by DAVID database. Active component-gastric ulcer target-KEGG pathway network was
constructed for Liangfu pill. In animal experiment，mice were randomly divided into blank group，model group，ranitidine group
（positive control，39 mg/kg），Liangfu pill low- ，medium- and high- dose groups （0.78，1.56，3.12 g/kg），and were given
corresponding drugs intragastrically，once a day，for consecutive 7 days. After last administration，except for blank group，the
other groups were given absolute ethanol （0.01 mL/g） intragastrically to induce the gastric ulcer model. After modeling，the
pathological changes of gastric tissue were observed and the gastric ulcer index was calculated；the expression of TP53，c-Jun，p38
MAPK，Akt，p-Akt and TNF-α protein in gastric tissues of mice were detected. RESULTS：A total of 9 active ingredients
（i.g. isorhamnetin，β-gsterol，kaempferol）and 166 common targets were screened in Liangfu pills. Liangfu pill can treat gastric
ulcer through GO functions such as cell response to chemical stimulation，protein binding and extracellular space，and KEGG
pathways such as cancer signaling pathway， hepatitis B，
