Effects of Radix Scrophulariae on Hyperthyroidism Assessed by Metabonomics and Network Pharmacology

Abstract

Radix Scrophulariae (Chinese name: Xuanshen), a traditional Chinese herb, is used for the treatment of hyperthyroidism, and in this study, its mechanisms were evaluated by metabonomics and system pharmacology. To study the anti-hyperthyroidism effects of R. Scrophulariae, a male SD rat (180–220 g) model of hyperthyroidism induced by Euthyrox was used. Thirty rats were randomly distributed into three groups: the Model group, the R. Scrophulariae treatment group (RS group) and the healthy Control group. Using the UHPLC/Q-TOF-MS metabolomics approach, 44 metabolites were found to be profoundly altered in the model group, and the levels of these biomarkers were significantly decreased after treatment with R. Scrophulariae. Forty-four metabolites and 13 signaling pathways related to R. Scrophulariae, including the biosynthesis of unsaturated fatty acids, primary bile acid biosynthesis and sphingolipid metabolism, were explored, and linoleic acid metabolism and sphingolipid metabolism were identified as the most relevant metabolic pathways. In addition, the system pharmacology paradigm revealed that R. Scrophulariae contains 83 active ingredients and is related to 795 genes, and 804 disease genes are related to hyperthyroidism. The construction of the R. Scrophulariaceae-chemical composition-target-hyperthyroidism network identified a total of 112 intersection genes. The enriched gene targets were analyzed, and five pathways were found to be enriched. Among them pathways, the HIF signaling pathway had the highest enrichment score, which indicated that this pathway might be the main signaling pathway related to the treatment of hyperthyroidism by R. Scrophulariae.The integrated approach involving metabolomics and network pharmacology revealed that R. Scrophulariae might play a role in the treatment of hyperthyroidism by regulating the “IL6-APOA1-cholesterol” pathway and disturbing the HIF signaling pathway. The results demonstrate that the combination of metabolomics and network pharmacology could be used to reflect the effects of R. Scrophulariae on the biological network and metabolic state of hyperthyroidism and to evaluate the drug efficacy of R. Scrophulariaceae and its related mechanisms.

Clinical Efficacy of Yiqi Yangyin Decoction Combined with Docetaxel on Advanced Ovarian Cancer and the Effect on the Levels of Serum Markers VEGF, HE4, and CA125

“…Pseudobulbus Cremastrae seu Pleiones and Prunella vulgaris can clear heat, remove toxicity, and reduce swelling, and the combination of the two drugs can accelerate the apoptosis of tumor cells. The combination of these drugs have the function of clearing heat and detoxifying, nourishing qi and Yin, strengthening the body resistance, thus promoting the body to secrete immune factors, with a good effect on adjuvant chemotherapy [ 24 – 27 ]. Our findings displayed that there was no obvious difference in adverse reactions between the two groups.…”

“…The overall factors attributed to TCMs and the human body have been comprehensively considered based on the overall concept and dialectical treatment. 7 Quercetin (QUE), being a kind of polyhydroxy flavonoid compound, is present in various vegetables and fruits and has a wide range of pharmacological effects, such as hypoglycemic, lipid-lowering, anti-inflammatory, antiviral, and anti-tumor activities, and promotion of an immune response. [8][9][10] Studies have found that QUE supplementation attenuated the TG and TC levels in high-fat dietfed mice in a dose-dependent manner.…”

Study on the Prognosis Effect of Traditional Chinese Medicine Treatment in DR Patients Based on the Perspective of Network Pharmacology

“…When the blood supply is poor for a long time, the terminal capillaries will be necrotic, and this part of the necrotic blood vessels will show large-scale bright spots or flocs on the retina. When the eyeball is in a state of hypoxia for a long time, the eyeball will proliferate new blood vessels to obtain oxygen and blood [11][12][13]. Figure 3 shows the retinal fundus image of the lesion, which contains the main lesion features.…”
