Background: Network pharmacology is widely used in mechanistic studies of traditional Chinese medicines (TCMs). The present study aimed to predict the target and signaling pathway of Baihe Decoction in the intervention of coronary heart disease (CHD) based on a network pharmacology approach and molecular docking.

Methods: The active ingredients of Baihe Decoction were screened by the Traditional Chinese Medicine Systems Pharmacology (TCMSP), and their potential target genes and proteins in CHD were predicted. The targets were screened out using Online Mendelian Inheritance in Man and the Genecards database. Venn soft was used to obtain the common targets of drugs and diseases. The compound-target-disease network of Baihe Decoction in CHD was constructed in Cytoscape, and the functional protein interaction network was obtained through the STRING database. ClusterProfiler and Pathview were used to perform Gene Ontology function analysis and KEGG pathway enrichment analysis of the effective targets of Baihe Decoction in CHD. Finally, we used MOE software for molecular docking of the compounds to their targets.

Results: Fifteen active components of Baihe Decoction in CHD were screened, which corresponded to 145 targets in CHD, including 30 targets with strong correlations. The key targets included Jun, Aktl, MAPK1, RELA, IL6, CXCL8, EGFR, MAPK14, ESR1, and FOS, which were found to play important roles in the treatment of CHD. The results of molecular docking further illustrated the roles that the compounds with quercetin and β-sitosterol play in the treatment of CHD through their interference with AKT1 and MAPK1 target proteins.

Conclusions: This study has preliminarily revealed the mechanism of Baihe Decoction in the treatment of CHD. The components of TCM may intervene in the processes of CHD occurrence and development by regulating cardiomyocytes and antioxidative stress, and by participating in inflammation and immune response. Moreover, in the clinical syndrome differentiation of TCM, Baihe Decoction can be used as the main drug to treat CHD and angina pectoris due to qi stagnation and blood stasis caused by emotional discomfort.

Coronary heart disease (CHD), also termed ischemic heart disease, is globally recognized as a serious, health-endangering disease that brings a substantial socioeconomic burden to patients and their families. Moreover, the morbidity and fatality rates of CHD are on the rise. According to a research paper published by The Lancet in June 2019, vascular disease is 2nd only to stroke as a leading cause of death in China. Between 1990 and 2017, the age-standardized death rate due to ischemic heart disease increased by 20.6% among the Chinese population (1).At present, traditional Chinese medicine (TCM) is attracting wide attention in the prevention and treatment of cardiovascular diseases due to its attributes of multi-component, multi-target, and multi-path regulation of the body, and fewer side effects.

“Shi Fang Ge Kuo” by Chen Xiuyuan, a well-known physician in the Qing Dynasty, describes 2 classic prescriptions for chest pain and heartache: Danshen Decoction and Baihe Decoction. These decoctions are widely used in the treatment of angina pectoris and other diseases in clinical practice. Multiple effects of Danshen Decoction on cardiovascular diseases have been evidenced, and Danshen-based drugs have proven extremely effective in the treatment of CHD (2-4). However, Baihe Decoction has been the focus of few research reports. Although the 2 decoctions are designed for heart pain caused by “qi stagnation” and “blood stasis”, both have a unique focus. Baihe Decoction consists of 2 medicinal plant extracts: Lily and Wu yao. Chen Xiuyuan stated that when “Long-time pain turns out to be stagnant, Baihe Decoction is suitable” (5). Based on preliminary clinical data, Zhang Lei, a master of TCM in Henan, successfully used Baihe Decoction to treat patients with stubborn symptoms of chest pain and heartache. He explained that Lily can control the “lung qi” and lower the qi of the viscera, promoting the smooth flow of the qi, with no pain: this is key to the effectiveness of Lily in treating heart pain. Baihe Decoction also has the beneficial effects of clearing “heat,” promoting qi, and relieving pain, and it is especially suitable for treating chest pain and heartache caused by stagnation of qi and blood stasis (6,7).

However, studies on Baihe Decoction have only explored its clinical use in the treatment of cardiovascular diseases, and the pharmacological mechanism of this TCM has yet to be the focus of a research report. In recent years, network pharmacology has been widely used in TCM researches leading to a number of interesting discoveries (8,9), especially in recent COVID-19 pandemic (10). Therefore, in the present study, using a network pharmacology approach, we screened the effective active ingredients of Baihe Decoction and their targets in CHD, predicted the related targets and signaling pathways, and constructed an active ingredient-target-disease network to explore the therapeutic mechanism of this decoction in CHD. We present the following article in accordance with the MDAR checklist (available at


Selection of chemical components in Baihe Decoction

We searched for the targets of action of all chemical components of “Lily” and “Wu yao“ through the Traditional Chinese Medicine Systems Pharmacology (TCMSP) Database and Analysis Platform ( According to the pharmacokinetic rules, as the restrictive screening conditions for obtaining the active ingredients of Lily and Wu yao, we set the oral bioavailability (OB) threshold at ≥30% and the drug-likeness (DL) threshold at ≥0.18 in the parameters of absorption, distribution, metabolism, and excretion (ADME). The study was conducted in accordance with the Declaration of Helsinki (as revised in 2013).

Collecting the target proteins of the active ingredients of Baihe Decoction

All the target proteins of the active ingredients of Baihe Decoction were collected through the TCMSP database, and the Uniprot protein database ( was used to convert the names of the collected target proteins into the ID names of the corresponding genes.

Obtaining the targets of Baihe Decoction in CHD

The Online Mendelian Inheritance in Man (OMIM, and the GeneCards ( databases were searched for CHD gene data. The results from the 2 databases were combined and integrated to obtain the gene target library of CHD. Then, the targets corresponding to the effective active ingredients of Lily and Wu yao and the target genes associated with CHD were compared. A Venn diagram was drawn and common target genes were screened out as potential targets of the active ingredients of Baihe Decoction in the treatment of CHD.

Construction of the drug-component-disease target network

The active ingredients of Baihe Decoction, their corresponding targets, and the target genes associated with CHD were entered into Cytoscape (version 3.7.1), and a drug-component-disease target network relationship diagram was constructed to clarify the potential interactions between CHD target genes and active ingredients of Baihe Decoction.

Construction of the target protein interaction network

The target proteins corresponding to the components of Baihe Decoction in CHD were imported into the STRING 11.0 database to construct the protein-protein interaction network (PPI). To obtain the PPI network, we set the species as “Homo sapiens” and the lowest interaction threshold as “combined-score” ≥0.9. The Cytoscape software was used to draw the PPI network visual diagram, and the PPI histogram was drawn using the barplot tool. Then, the top 30 core target protein genes were ordered according to the strength of the protein interaction.

Gene function and pathway enrichment analysis

The R language clusterProfiler and pathview packages were used to perform Gene Ontology (GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. The results were presented in the form of a histogram and a bubble chart. The key signaling pathways were screened by the enrichment factor value and enrichment degree, and the mechanism by which Baihe Decoction interferes with biological processes and metabolic pathways in CHD was investigated.

Molecular matching of Baihe Decoction ingredients and key target proteins

The crystal structures of the candidate proteins bound by the important compounds of Baihe Decoction were downloaded from the Protein Data Bank (PDB) protein structure database ( To ensure accuracy and consistency, Molecular Operating Environment (MOE) 2015 software was used to remove ligands and to add hydrogen, remove water, optimize and repair amino acids, and minimize the energy of all candidate targets. MOE was used to test the matching accuracy between Baihe Decoction compounds and candidate target protein, due to its high levels of accuracy and consistency.

Statistical analysis

All statistical process were concuted in software mentioned before respectively.


Active ingredients in Baihe Decoction

A total of 212 chemical constituents of Baihe Decoction were retrieved from the TCMSP database including 84 and 128 chemical constituents for Lily and Wu yao, respectively. With OB ≥30% and DL ≥0.18 as indicators, 16 biologically active ingredients were screened out (Table 1), including 7 active ingredients of Lily and 9 active ingredients of Wu yao. Among the chemical ingredients, beta-sitosterol was found in both Lily and Wu yao. By combining ADME characteristics, we identified 15 chemical components in Baihe Decoction with good bioavailability. The analysis of the drug composition of Lily showed that, chemically, it is mainly composed of steroidal saponins, such as stigmasterol, β-sitosterol, and cholesstanol glycosides (26-O-β-D)-glu-3β, 26-dihydroxy cholestan-16, 22-dioxo-3-O-α-rha (1→2)-β-D-glucoside; 26-O-β-D-glu-3β, 26-dihydroxy-5-cholesten-16, 22-dioxo-3-O-α-rha (1→2)-β-D-glucoside). For Wu yao, flavonoids (quercetin and nubigenol), alkaloids (norboldine and boldine), terpenoid lactones (Agropyrone C09495), and sitosterol were found to be the active ingredients.

Predicted target genes of Baihe Decoction

A total of 5,552 CHD-related target genes were obtained through searches of the OMIM and GeneCards databases. Following deduplication, 5,282 target genes associated with CHD were finally obtained. The potential target genes of the drugs in Baihe Decoction were matched with the CHD-related genes, and Venn 2.1 software was used to draw a Venn diagram, which is shown in Figure 1. A total of 145 CHD-related target genes were identified for Baihe Decoction, accounting for 86.8% of the total targets of active ingredients of this TCM. This result indicated Baihe Decoction to have a strong effect on CHD, as well as a high research value.

Network construction and analysis of active ingredients in Baihe Decoction and CHD

The active ingredients of Baihe Decoction and the corresponding target proteins of CHD were imported into Cytoscape, and a visual network diagram was constructed (Figure 2). The network comprised 162 nodes, 145 target proteins corresponding to the disease, and 267 edges. The results showed that the 15 effective components of Baihe Decoction, corresponding to CHD-related genes, including RXRA, PGR, PTGS2, NCOA2, NCOA1, NR3C2, ADH1C, PTGS1, ADRA2A, SLC6A2, ADRB2, AKR1B1, PLAU, LTA4H, MAOB, MAOA, 145 target genes such as CHRM3, CHRM1, ADRB1, SCN5A, and ADRA1A.

Analysis of the Baihe Decoction Gene Protein Interaction Network

The 145 target proteins of Baihe Decoction in CHD were imported into the STRING database and then the PPI data were imported into Cytoscape software. A protein relationship network diagram was drawn (Figure 3), and the top 30 target genes were arranged according to the enrichment degree. They included the proto-oncogene Jun, serine/threonine kinase 1 (Aktl), mitogen activated protein kinase 1 (MAPK1), v-rel reticuloendothelial hyperplasia virus oncogene homolog A (RELA), interleukin-6 (IL6), interleukin-8 (CXCL8), epidermal growth factor receptor (EGFR), mitogen activated protein kinase 14 (MAPK14), estrogen receptor (ESR1) and proto-oncogene FOS, respectively. At the same time, the PPI histogram in Figure 4 revealed the Jun, Aktl, MAPK1, RELA, and IL6 genes to have more than 20 adjacent nodes, indicating that these genes have important interactions in the protein network.

GO biological functional analysis of Baihe Decoction

GO functional analysis of the key targets of Baihe Decoction in the treatment of CHD was performed, including biological processes (BPs), molecular functions (MFs), and cellular components (CCs). The top 20 BPs with the smallest P value were analyzed. In terms of BPs (Figure 5A), the targets of Baihe Decoction in CHD were mainly enriched in lipopolysaccharide reaction, bacterial source molecular reaction, oxygen level reaction, reactive oxygen metabolism, steroid hormone reaction, nutrient level reaction, oxygen deficiency response, oxidative stress response, blood circulation, and circulatory system processes. In terms of MFs (Figure 5B), the targets were mainly involved in nuclear receptor activity, DNA binding transcription activation activity, steroid hormone receptor activity, adrenaline receptor activity, cytokine receptor binding, heme binding, RNA polymerase II transcription factor binding, and G protein-coupled amine receptor activity. In terms of CCs (Figure 5C), the targets were mainly enriched in the plasma membrane, mitochondria, RNA polymerase II transcription factor complex, nuclear transcription factor complex, nuclear chromatin, and protein kinase complex. These results suggested that Baihe Decoction plays a therapeutic role CHD by regulating multiple complex BPs.

KEGG pathway enrichment analysis

KEGG pathway enrichment analysis (Figure 6 and Table 2)was carried out to screen the signaling pathways in which the targets of Baihe Decoction are most significantly enriched. The top 15 most enriched signaling pathways were all significantly correlated to CHD. The most enriched pathway was the phosphatidylinositol 3-kinase/protein kinase (PI3K-Akt) B signaling pathway, followed by the MAPK signaling pathway, the hypoxia-inducible factor 1 (HIF-1) signaling pathway, endocrine resistance, cellular senescence, apoptosis, the Toll-like receptor signaling pathway, the C-type lectin receptor signaling pathway, the calcium signaling pathway, the ErbB signaling pathway, and the NF-κB signaling pathway.

Molecular matching results

To further verify the candidate compounds for the Baihe Decoction targets in CHD, we tested the matching accuracy of quercetin and beta-sitosterol with AKT1 (PDB: 4GV1), and MAPK1 (PDB: 6OPH). These target proteins were chosen for study due to their key positions in the PPI network and their participation in key pathways, which suggested that they may play a key role in the response of CHD to Baihe Decoction compounds. The best matching attitude is the root mean square deviation (RMSD) between the predicted conformation and the observed X-ray crystal conformation reach the lowest limit. A model with RMSD 4Å is considered reliable, and a model with RMSD 2Å is considered accurate. The final score of the overall evaluation is E_score2. The smaller the corresponding value, the smaller the binding energy between molecules, which reflects better binding between the 2 (generally less than −5).

We also mapped the three-dimensional conformation of the matching of quercetin and β-sitosterol with AKT1 and MAPK1 (Figure 7A,B), and marked the structure of small molecules with different colors. A structural space between the 2 maps where there were larger repeat regions could be observed, proving that there was great similarity between the conformation of the small molecule and the ligand. The results of the matching analysis showed that the scores of the target proteins and the corresponding compound molecule were less than −5, indicating that the target proteins and the compound molecules had good binding properties (Table 3). The matching analysis successfully predicted that quercetin and β-sitosterol would bind well to the 2 active sites of the tested target proteins.

CHD is caused by atherosclerosis of coronary arteries and can lead to myocardial ischemia, hypoxia, and even necrosis. It mainly manifests as angina, myocardial infarction, arrhythmia, and heart failure (8). In recent years, studies have confirmed that interventions with TCM can reduce the incidence of acute adverse cardiovascular events among patients with CHD (9). TCM symptom differentiation and treatment plays an indispensable role in preventing and treating this disease; however, it also faces challenges in the era of precise medicine. With the rapid progress of network pharmacology, Chinese medicine research also made significant development. Many classical Chinese medicine regimens have been deeply studied and outstanding results have been reached (8,9).

In this study, we found that the effective ingredients of Baihe Decoction, Lily and Wu yao, mainly contain sterols, saponins, alkaloids, and flavonoids. Modern pharmacology has shown that Lily has antioxidative, anti-inflammatory, anti-depression, anti-tumor, hypoglycemic, anti-stress damage, immune regulatory, and other biological activities (11). It can also inhibit the body's absorption of cholesterol, promote cholesterol degradation, lower plasma triglyceride levels, and prevent and treat coronary atherosclerosis (12-14). Wu yao has anti-inflammatory, analgesic, anti-tumor, and antioxidative effects, and can lower blood pressure, regulate gastrointestinal motility, protect the liver, excite the myocardium, and regulate blood coagulation (15). A study by Han (16) focusing on quercetin, as the active ingredient with the highest content of flavonoids in Wu yao, concluded that quercetin has good antioxidant and blood stasis-removing effects, which is of great significance for treating cardiovascular diseases. By conducting in vivo experiments, Chen et al. (17) found that quercetin can upregulate the expression of NF-κB p65 and TLR2 protein, promote the recovery of immune organ function, and increase the body’s antioxidant levels, as well as improve the immune function of mice. Han et al. (18) found that the effective components of Wu yao leaves can block the TLR-4/NF-κB signaling pathway and play a role in lowering lipids and liver protection.

Domestic studies have also proposed the possible existence of an evolutionary law of the occurrence and development of CHD. The proportion of patients with qi stagnation after intervention for CHD is significantly increased. Major surgery and other factors can result in mental trauma for patients (19), and more than 30% of patients with CHD have depressive symptoms (20). Lily can relieve the symptoms of depression and anxiety by increasing the content of serotonin and dopamine, thus improving monoamine neurotransmitter insufficiency, reducing the levels of hypothalamic corticotropin-releasing factor, and increasing the pathway of hippocampal glucocorticoid receptor messenger RNA. The effective ingredients of Lily, including 26-O-β-D-glu-3β, 26-dihydroxy-Δ-5-choleslen-16-22-dioxo-3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside, are all anti-depressant substances (21,22). Wu yao has the functions of soothing the liver, regulating qi, promoting qi, and relieving depression. The alkaloids in Wu yao can bind to nicotinic acetylcholine receptors by regulating the release of dopamine neurotransmitters, and act on ADPH1, CDK2B, and DA protein targets to motivate qi and relieve pain (15). According our research results, Baihe Decoction may be a valuable treatment for CHD accompanied by depression. It can be used as the main medicine to treat depressive symptoms associated with interventional surgery and previous myocardial infarction.

In this study, through the analysis of PPI protein interactions, the main targets of Baihe Decoction were found to be Jun, Aktl, MAPK1, RELA, IL6, CXCL8, EGFR, MAPK14, ESR1, and FOS, which act on RXRA, PGR, PTGS2, NCOA2, NCOA1, NR3C2, ADH1C, PTGS1, ADRA2A, SLC6A2, ADRB2, AKR1B1, and other target genes. These core target proteins participate in multiple inflammation, immunity, metabolism, and cell proliferation–related signaling pathways to treat CHD. Jun and FOS are oncoproteins which have the functions of transcription, and regulation of cell growth and metabolism. They can also form FOS-Jun complexes, which can regulate the expression of IL-6 and IL-1β, as well as inflammatory responses. FOS-Jun complexes is effective in myocardial ischemia, myocardial infarction, and postoperative restenosis, and plays an important role in the pathogenesis of various cardiovascular systems (23). Akt1 is 1 of serine/threonine protein kinases which regulates inflammation, immunity, and cell metabolism via signaling pathways including P13K-Akt and MAPK. Studies analyzing the GSE18612 and GSE64554 gene maps of epicardial adipose tissue of patients with CHD concluded that the AKT1 gene can serve as 1 of the main biomarkers and therapeutic targets of CHD (24). MAPK1 and MAPK14 are members of the MAPK family, which can phosphorylate and activate the expression of transcription factors and downstream genes, and play a role in the regulation of cell survival and death, as well as inflammation (25). RELA is a transcription factor of the NF-κB family which can regulate cell adhesion, infiltration, metastasis, and numerous other processes. Its enhanced expression can promote the occurrence and development of atherosclerosis (26). IL6 and CXCL8 are both pro-inflammatory cytokines which are involved in the pathological process of inflammation as regulators of inflammatory response. Through a comparison of the biological network characteristics of angina pectoris of CHD with Qi deficiency and blood stasis syndrome, and Qi stagnation and blood stasis syndrome (27), Liu found that EGFR, IL6, AR, CHRM2, PPARA, IL2, EGF, and ESR1, which were identified as key targets of Baihe Decoction in this study, were the key genes of Qi stagnation and blood stasis syndrome. Therefore, using Baihe Decoction in the treatment of CHD caused by qi stagnation and blood stasis would be reasonable. This finding is highly consistent with clinical application and, to a certain extent, reflects the role of network pharmacology in predicting the mechanism of drug action.

GO and KEGG enrichment analyses found that Baihe Decoction mainly regulates nuclear receptor activity, DNA binding transcription activation activity, steroid binding, cytokine receptor binding, heme binding, and RNA polymerase II transcription factor binding to participate in coronary artery inflammation and immune responses (28), such as lipopolysaccharide response, bacterial molecular source response, oxidative stress response, steroid hormone response, and other biological processes related to CHD. Its mechanism of action mostly involves anti-inflammatory and antioxidative stress effects, to which the PI3K-Akt, MAPK, and HIF-1 signaling pathways are closely related. The PI3K-Akt signaling pathway is an important signal transduction pathway that regulates cardiac function mainly by activating PI3K, binding downstream Akt, phosphorylating Akt, initiating downstream target gene transcription, and regulating the growth and survival of cardiomyocytes and blood vessels. Regeneration and maintenance of cardiac systolic function, regulation of signal transduction, and induction of cell autophagy all affect the atherosclerotic process (29). Ren et al. (30) observed that sphingosine 1-phosphate can effectively inhibit cardiomyocyte apoptosis in CHD rats by regulating the expression of related proteins in the PI3K/Akt signaling pathway. The MAPK signaling pathway transmits signals from the cell membrane to the nucleus in response to various stimuli, and also participates in the signal transduction of various growth factors, cytokines, mitogens, and hormone receptors after activation. It plays an important regulatory role in cell growth and apoptosis, inflammation, and stress response (31,32). Zuo et al. (33) reported that genetic polymorphisms in MAPK genes may affect blood lipid metabolism and coagulation function in CHD, and participate in inflammatory reactions. HIF-1, as part of the HIF-1 signaling pathway, acts as the main regulator of oxygen homeostasis and is extremely important to the body's response to low oxygen levels or hypoxia. It is a key regulator of stimulation not only in myocardial hypoxia but also in myocardial stress (34). Studies such as that by Zhang et al. (35) found that the HIF-1 signaling pathway upregulates vascular endothelial growth factor, nitrous oxide, reactive oxygen species, and platelet-derived growth factor by acting on the specific response of vascular endothelial cells, smooth muscle cells, and macrophages, subsequently resulting in endothelial cell dysfunction, proliferation, angiogenesis, and inflammation. Targeting HIF-1 may become 1 of the key therapeutic strategies for coronary atherosclerosis (36). However, in brief, drug innovation and research through network pharmacology include several steps: network construction, network analysis and network verification; then experimental studies and clinical researches are warranted to confirm the results of network pharmacology. The major difficulty is the multiple possible targets derived from network pharmacology. How to select the best one remains a challenge for investigators.

In conclusion, this study has provided theoretical evidence that Baihe Decoction may interfere with the occurrence and development of CHD by regulating cardiomyocyte proliferation, transcription, and apoptosis, protecting against oxidative stress damage, and participating in inflammation and immune responses and other pathways. The PI3K-Akt, MAPK, HIF-1 signaling pathways may be the most important pathways involved in the effects of Baihe Decoction on CHD. Preliminarily, this study speculates that the effective active ingredients of Baihe Decoction convert extracellular signals into cellular responses through receptor tyrosine kinase (RTK), and activate and promote the phosphorylation of Akt, thereby regulating RTK-PI3K-AKT signaling pathways, which plays a role in CHD. The results of molecular matching also showed that the compounds quercetin and β-sitosterol in Baihe Decoction exert their therapeutic effects by interfering with the target proteins of AKT1 and MAPK1, proving that these 2 proteins act as the target proteins of quercetin and β-sitosterol in CHD. Sterol has high credibility as a therapeutic target. Overall, our results provide further evidence for the use of Baihe Decoction in the treatment of CHD. However, this study has some limitations. First of all, pharmacodynamic markers of the regulatory effects of Baihe Decoction on CHD need to be further verified by experimental studies. Second, based on the present results, it is hard to determine the main mechanism involved in the effect of Baihe Decoction on CHD and there is still a lot work to do.
