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. 展开更多

以呼和浩特市区为例,通过收集历史内涝数据与实地调查,共收集到78处积水点的具体位置、内涝范围和发生频率等实际数据,并对其内涝成因进行分析。结果表明:2016—2019年内涝灾害较2010—2016年频繁;其次,内涝主要发生在6—9月间,尤其集中... 以呼和浩特市区为例,通过收集历史内涝数据与实地调查,共收集到78处积水点的具体位置、内涝范围和发生频率等实际数据,并对其内涝成因进行分析。结果表明:2016—2019年内涝灾害较2010—2016年频繁;其次,内涝主要发生在6—9月间,尤其集中在7月。空间分布特征表明,赛罕区积水点分布密度最大,而玉泉区最小。相关性分析表明,呼和浩特市区暴雨日数虽然少(1961—2018年),但暴雨日的降水总量占比高,平均占比22.0%,最高占比39.3%。此外,93.59%的积水点位于低洼地点;再者,雨水管线流量较低造成积水面积增大。综上所述,极端降水和地势等自然因素导致雨水地表流量大、积流多并存在较多低洼地区形成内涝;而城市排水系统无法满足排水需求等人为因素造成雨水管线流量过小造成积水面积过大而形成内涝。 展开更多
