The bio-active components of the Mongolian medicine Horcha-6 and therapeutic mechanism in the rat migraine model

Background:The active components of Horcha-6 were identified using liquid chromatography with tandem mass spectrometry.Also,we investigated the potential mechanisms that explain why Horcha-6 may be effective in treating migraines through the use of network pharmacology and a rat migraine model.Methods:After identifying the active components of Horcha-6,the corresponding genes of the active components’target were obtained from the Universal Protein database,and a“compound-target-disease”network was constructed using Cytoscape 3.9.0 software.For the in vivo experiments,nitroglycerin was injected intraperitoneally into rats to create a migraine model.Pre-treatment with Horcha-6 was administered orally for 14 days,and rats were subjected to migraine-related behavior tests.RNA sequencing was performed to identify the gene expression regulated by Horcha-6 in the trigeminal nerve.Results:A total of 903 chemical components of Horcha-6 have been collected in the liquid chromatography with tandem mass spectrometry.We discovered 55 of the Horcha-6 bio-active components that were evaluated based on their Percent Human Oral Absorption(≥30%)and DL values(≥0.185)on the traditional Chinese medicine systems pharmacology database.The“compound-target-disease”network contained 163 intersection targets with the migraine state.Gene Ontology analysis indicated that these components significantly regulated the immune response,vascular function,oxidative stress,etc.When Kyoto Encyclopedia of Genes and Genomes enrichment analysis was performed,we observed that most of the target genes were significantly enriched in the inflammation and neuro-related signaling pathway,toll-like receptor signaling pathway,neuroactive ligand-receptor interaction,etc.These predictions were further demonstrated via in vivo animal model experiments.The RNA sequencing results showed that 41 genes were down-regulated(P<0.05)and 86 genes were up-regulated(P<0.05)in the Horcha-6 treated group compared with the untreated group.Those genes were mainly involved in neuromodulation,vascular function,and hormone metabolism.Conclusion:The 55 bio-active components in Horcha-6 regulate inflammation,hormone metabolism,and neurotransmitters and have potential as a therapy to treat migraines.

Protective Effects of Mongolian Medicine Borantunggal on Rats with Chronic Renal Insufficiency

[Objectives]To observe the protective effects of Mongolian medicine Borantunggal on rats with chronic renal insufficiency.[Methods]Male Wister rats were gavaged with 50 mg/kg/d adenine for 12 consecutive weeks,and were intervened with positive control drug Niaoduqing and three groups of different doses of Mongolian medicine Borantunggal.The rats general state,such as body posture,hair color,activity status,renal function,thyroid gland,adrenal gland,and gonadal hormone levels,expression levels of inflammatory mediators,α-smooth muscle actin(α-SMA)and nuclear factor-κB(P65)in renal tissue,and histopathological changes of rat kidney were observed before and after treatment.[Results]The recovery of the general state of rats with chronic renal insufficiency in the low dose group after intervention with Mongolian medicine Borantunggal was the most obvious.Compared with the model group,the level of CRE in the low dose Mongolian medicine group decreased,and the difference was statistically significant(P<0.05).Compared with the normal group,the 24-h urinary protein in the low dose Mongolian medicine group had a declining trend,but the difference was not statistically significant(P>0.05).The urea level in low,medium and high dose Mongolian medicine groups showed a declining trend,and the effect of low dose Mongolian medicine was better.Compared with the model group,the feed intake of the low dose Mongolian medicine group had an increasing trend,while P and TCHO also had a declining trend.Compared with the model group,the levels of LH and COR in the low,medium and high dose Mongolian medicine groups decreased significantly,and the difference was statistically significant(P<0.05).The levels of T,T3 and T4 were significantly increased,the difference was statistically significant(P<0.05),and the effect of low dose Mongolian medicine was better.Compared with the model group,the levels of IL-6,TNF-αand HIF-1 in the low,medium and high dose Mongolian medicine groups were significantly reduced,and the difference was statistically significant(P<0.05).The levels of TGF-β1 and Ang II in the low dose Mongolian medicine group were significantly reduced,and the difference was statistically significant(P<0.05).The level of TGF-β1 in the medium and high dose Mongolian medicine groups decreased,and the difference was statistically significant(P<0.05).The expression of NF-κB P65 andα-SMA proteins in the low dose Mongolian medicine group showed a declining trend,which was better than Niaoduqing.[Conclusions]Mongolian medicine Borantunggal has significant protective and preventive effects on rats with adenine-induced chronic renal insufficiency.In particular,the dose of 0.31 kg/d had the most significant protective effect.Its action mechanism may be related to regulating hormone levels in the body,improving renal function,reducing renal inflammatory response,reducing the"three highs"in the kidney,and inhibiting renal tubular epithelial cell-to-mesenchymal transition and deposition of extracellular matrix(ECM).

Metabolic Characterization of the Badagan Constitution in Mongolian Medicine by Ultrahigh-Performance Liquid Chromatography/Quadrupole Time-of-Flight Mass Spectrometry/MS

This study aimed to identify the potential metabolic biomarkers of the Badagan constitution(BC) in Mongolian medicine. Serum samples from the participants with BCs(n = 32) and aggregative constitutions(n = 30) were analyzed by using ultrahigh-performance liquid chromatography/mass spectrometry. Meanwhile, principal component analysis and orthogonal partial least squares discriminant analysis were used to characterize the endogenous metabolites and potential biomarkers, respectively. Fifteen of the 18 biomarkers in six metabolic pathways were significantly upregulated,including phosphatidylserine, sphingolipids, tryptophan, riboflavin and glutathione, and three biomarkers were significantly downregulated,including lysophosphatidylcholine(LysoPC)(18:1), LysoPC(16:1), and lysophosphatidylethanolamine(LysoPE)(22:2). This study also implied that sphingolipid metabolism, glycerophospholipid metabolism, and tryptophan metabolism played important roles in the BC. Therefore, metabolomics may improve the diagnostic efficacy of the BC in terms of the accuracy and comprehensiveness of a diagnosis based on this constitution. This result further reveals the mechanism of the constitution type in Mongolian medicine and provides a reference for the treatment of related diseases.
