Chronic heart failure (CHF) is a severe condition that affects millions of people worldwide. Despite standardized treatments, patients often face recurrent symptoms such as dyspnea, edema, and fatigue, which impair their quality of life and contribute to high mortality and hospital readmission rates. Traditional Chinese Medicine (TCM) offers alternative therapies, and Qishen Yiqi Dropping Pills (QYDP) has emerged as a potential treatment for CHF. QYDP is composed of Danshen, Huangqi, Jiangxiang, and Sanqi and is known for its ability to promote circulation, enhance Qi, and support cardiac health. Although clinical studies have suggested that QYDP can alleviate CHF symptoms, the underlying molecular mechanisms are not fully understood. In this study, network pharmacology and molecular docking were used to explore the pharmacological targets of QYDP for CHF treatment. Four core genes were identified: AKT1, HIF1A, STAT3, and MYC. Molecular docking confirmed the interactions between these genes and active compounds in QYDP, such as kaempferol, luteolin, quercetin, tanshinone IIa, and cryptotanshinone. These findings suggest that QYDP may treat CHF through a multitarget mechanism, offering new insights into its therapeutic potential and providing a basis for further clinical research.
CHF, cardiovascular disease, QYDP, traditional Chinese medicine
Chronic heart failure (CHF) is a challenging and multifaceted clinical syndrome characterized by progressive deterioration of cardiac structure and function due to various factors (
Qishen Yiqi Dropping Pills (QYDP) have been widely used for the treatment of CHF because they can improve certain symptoms caused by insufficient Qi and blood as a type of Traditional Chinese medicine (TCM), renowned for having few adverse effects and long-lasting benefits (
Collectively, these findings highlight the pharmacological effects of QYDP in treating CHF. Several studies have shown that QYDP protects the myocardium in rats with CHF by enhancing cardiac angiogenesis, reducing myocardial fibrosis, improving cardiomyocyte hypertrophy, and inhibiting myocardial apoptosis (
The traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP) was used to identify the active QYDP constituents (
The Venn package (
To further explore the network characteristics of the protein-protein interaction (PPI), we used the STRING database and CytoNCA plugin in Cytoscape 3.8.0 software (
For molecular docking, we collected the core chemical compounds of QYDP and selected the core genes from gene enrichment and network characteristic analyses. We obtained the 2D structures of these compounds using PubChem (
Compounds in QYDP and corresponding target genes
A total of 108 active QYDP constituents were identified: 65 from Danshen, 20 from Huangqi, 15 from Jiangxiang, and eight from Sanqi. A total of 2390 target genes associated with the active compounds of QYDP were identified, including 932 target genes of Danshen, 953 target genes of Huangqi, 252 target genes of Jiangxiang, and 253 target genes of Sanqi. Ultimately, we obtained 1631 target genes. A total of 218 gene targets were obtained after the deletion of duplicate genes, as shown in Fig.
After removing the overlapping genes, we obtained a total of 2915 genes related to CHF, including 2818 genes from the GeneCards database (the screening criterion was a relevance score > 10), 152 genes from the DrugBank database, 268 genes from the OMIM database, 16 genes from the PharmGKB database, and 13 genes from the TTD database (Fig.
After eliminating duplicate genes using the R language Venn package, 218 therapeutic gene targets for QYDP and 2915 disease-related gene targets for CHF were identified. As illustrated in Fig.
From the GO enrichment analysis of the intersecting genes, we obtained 2283 biological processes, 218 molecular functions, and 77 cellular components using a screening criterion of a q value < 0.05. The top ten terms were visualized according to the q value (Fig.
Based on six parameters of the CytoNCA plugin, a PPI network of 117 overlapping genes was constructed using two filters. We acquired 36 nodes (genes) and 151 edges using the first filter (Fig.
We selected the core compounds of QYDP, namely kaempferol, luteolin, quercetin, tanshinone IIa, and cryptotanshinone, and four genes for molecular docking, namely HIF1A, MYC, STAT3, and AKT1. Combining the results of network characteristics and gene enrichment analyses, as shown in Table

Previous research has demonstrated that CHF patient mortality is increasing globally, and optimizing CHF treatment may improve patient survival rates (
According to our network pharmacology investigation, QYDP improved cardiac function through multiple targets and pathways. Moreover, we also observed some targets that have been experimentally verified to be related to the efficacy of QYDP, such as Bax, VEGF, and caspase-3, although the corresponding genes of the above proteins were excluded during the screening of the key genes, confirming to a certain extent that our study has reference value for the discovery of the pharmacological effects of QYDP in CHF. GO analysis revealed that the majority of the overlapping genes were responsible for phosphatase binding, oxidative stress, and other processes. According to KEGG analysis, fluid shear stress, atherosclerosis, and the TNF, IL-17, and PI3K-Akt signaling pathways were the major enriched pathways for the overlapping genes. Overall, network pharmacology revealed 12 key genes, including CDKN1A, JUN, MAPK1, RB1, TP53, MAPK14, CCND1, and RELA, and in particular, STAT3, HIF1A, MYC, and AKT1.
All four core gene targets have proven roles in CHF treatment. The signal transducer and activator of transcription 3 (STAT3) is necessary for several biological processes, notably cell proliferation and death. According to a previous study, astragaloside IV can reduce HF through the JAK-STAT3 pathway (
In this study, quercetin, kaempferol, luteolin, tanshinone IIA, and cryptotanshinone were screened from the compounds of QYDP using the TCMSP based on their better OB and DL. Many studies have shown that these compounds have anti-apoptotic, antioxidative, and anti-inflammatory effects. The TNF and the PI3K-Akt pathway are involved in treating multiple cardiovascular diseases with quercetin (
Trimetazidine directly improves myocardial metabolism in both clinical and basic studies (
This network pharmacology study provides evidence for the use of QYDP in the treatment of CHF by identifying potential targets and providing insights into the mechanisms of action of QYDP in the treatment of CHF. AKT1, Myc, HIF1A, and STAT3 are potential targets of QYDP in CHF treatment, highlighting the potential of QYDP as an alternative and complementary therapy. Further experimental validation is warranted to confirm these findings and to elucidate the specific roles of the identified targets and pathways.
