Objective
2
To explore the mechanism of Xueniao capsule in the treatment of acute pyelonephritis (APN) by network pharmacology and experimental verification.
Method
2
The effect of Xueniao capsule on APN was investigated based on the APN model in rats. The Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), Chemistryl Database, and SymMap were searched for the chemical components of Smilacis Chinae Rhizoma,Coicis Semen, and Trachycarpi Petiolus. The target information of the components was collected from PharmMapper and SwissTargetPrediction, and disease target information from Therapeutic Target Database (TTD), DrugBank, DisGeNET, GeneCards, and Online Mendelian Inheritance in Man(OMIM). The key genes of Xueniao capsule for APN underwent Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analyses by Metascap. Real-time quantitative polymerase chain reaction (PCR) and Western blot were employed to verify the prediction results.
Result
2
Compared with the blank group and the sham operation group, the model group showed an increased ratio of the left kidney to the right kidney and organ index(
P
<
0.05,
P
<
0.01),up-regulated white blood cells (WBC),neutrophils (NEUT),monocytes (MONO), and lymphocytes (LY)(
P
<
0.05,
P
<
0.01), and elevated levels of nuclear factor-
κ
B(NF-
κ
B), interleukin-6 (IL-6), and tumor necrosis factor-
α
(TNF-
α
)(
P
<
0.05,
P
<
0.01). Compared with the model group, the norfloxacin group, the low- and high-dose Xueniao capsule groups showed a decreased ratio of the left kidney to the right kidney and organ index(
P
<
0.05,
P
<
0.01), dwindled levels of WBC, NEUT, MONO, and LY(
P
<
0.05,
P
<
0.01), and reduced levels of NF-
κ
B, IL-6, and TNF-
α
(
P
<
0.05,
P
<
0.01). The medium-dose Xueniao capsule group showed a decreased ratio of the left kidney to the right kidney and organ index(
P
<
0.05,
P
<
0.01), reduced levels of WBC, NEUT, MONO, and LY(
P
<
0.05,
P
<
0.01), and dwindled levels of IL-6 and TNF-α(
P
<
0.05,
P
<
0.01). Network pharmacological analysis revealed 17 active compounds from Smilacis Chinae Rhizoma, 18 active compounds from Coicis Semen, six active compounds from Trachycarpi Petiolus, and 39 key genes for the treatment of APN in Xueniao capsule. GO enrichment analysis demonstrated 704 biological processes, 22 cellular components, and 59 molecular functions. Sixty-two pathways were enriched in KEGG enrichment analysis. The experimental verification results showed that compared with the blank group, the model group showed increased mRNA expression of prostaglandin-endoperoxide synthase 2 (PTGS2), mitogen-activated protein kinase 1 (MAPK1)/extracellular signal-regulated protein kinase 2 (ERK2),phosphoinositide 3 kinase (PI3K),protein kinase B2(Akt2),Janus kinase 2 (JAK2),and signal transducer and activator of transcription 3 (STAT3)and protein expression of PI3K, Akt2, JAK2, and STAT3 (
P
<
0.05,
P
<
0.01). Compared with the model group, the low-dose Xueniao capsule group showed decreased mRNA expression of MAPK1, PI3K, JAK2, and STAT3 and protein expression of PI3K, JAK2, and STAT3 (
P
<
0.05,
P
<
0.01). The medium-dose Xueniao capsule group showed decreased mRNA expression of MAPK1, PTGS2, PI3K, JAK2, and STAT3, and protein expression of PI3K, JAK2, and STAT3 (
P
<
0.05,
P
<
0.01). The high-dose Xueniao capsule group showed reduced mRNA expression of PTGS2, MAPK1, PI3K, Akt2, JAK2, and STAT3 and protein expression of PI3K, Akt2, JAK2, and STAT3 (
P
<
0.05,
P
<
0.01).
Conclusion
2
Xueniao capsule has a certain curative effect on APN via multiple targets and multiple pathways. The mechanism may be related to the inhibition of the PI3K/Akt signaling pathway and the JAK2/STAT3 signaling pathway.
