ABSTRACT

The current study was designed to explore the brain protection mechanism of Xinglou Chengqi Decoction (XCD) based on gut microbiota analysis and network pharmacology. A transient middle cerebral artery occlusion (MCAO) model of mice was established, followed by behavioral evaluation, TTC and TUNEL staining. Additionally, to investigate the effects of gut microbiota on neurological function after stroke, C57BL/6 mice were treated with anti-biotic cocktails 14 days prior to ischemic stroke (IS) to deplete the gut microbiota. High-throughput 16S rDNA gene sequencing, metabonomics technique, and flow multifactor technology were used to analyze bacterial communities, SCFAs and inflammatory cytokines respectively. Finally, as a supplement, network pharmacology and molecular docking were applied to fully explore the multicomponent-multitarget-multichannel mechanism of XCD in treating IS, implicated in ADME screening, target identification, network analysis, functional annotation, and pathway enrichment analysis. We found that XCD effectively improved neurological function, relieved cerebral infarction and decreased the neuronal apoptosis. Moreover, XCD promoted the release of anti-inflammatory factor like IL-10, while down-regulating pro-inflammatory factors such as TNF-α, IL-17A, and IL-22. Furthermore, XCD significantly increased the levels of short chain fatty acids (SCFAs), especially butyric acid. The mechanism might be related to the regulation of SCFAs-producing bacteria like Verrucomicrobia and Akkermansia, and bacteria that regulate inflammation like Paraprevotella, Roseburia, Streptophyta and Enterococcu. Finally, in the network pharmacological analysis, 51 active compounds in XCD and 44 intersection targets of IS and XCD were selected. As a validation, components in XCD docked well with key targets. It was obviously that biological processes were mainly involved in the regulation of apoptotic process, inflammatory response, response to fatty acid, and regulation of establishment of endothelial barrier in GO enrichment. XCD can improve neurological function in experimental stroke mice, partly due to the regulation of gut microbiota. Besises, XCD has the characteristic of "multi-component, multi-target and multi-channel" in the treatment of IS revealed by network pharmacology and molecular docking.

ABSTRACT

In recent years, the incidence of neurological diseases has been increasing year by year. To give full play to the advantages of traditional Chinese medicine (TCM) in the treatment of neurological disorders, identify the breakthrough point of integrating TCM with western medicine, and further standardize the clinical diagnosis and treatment of TCM, the China Association of Chinese Medicine organized neurologists in TCM and western medicine to carry out in-depth discussion on the neurological diseases responding specifically to TCM and integrated TCM and western medicine, such as stroke, headache, vertigo, multiple sclerosis, and epilepsy, aiming to formulate a well-recognized and integrated treatment protocol for TCM and western medicine and improve the efficacy of neurological disorders. Furthermore, the treatment suggestions of the corresponding diseases in TCM and western medicine were proposed to provide references for clinical practice and scientific research.

ABSTRACT

<p><b>OBJECTIVE</b>To study the efficacy of modified Wuzhuyu Decoction Granule (, MWDG) in the treatment of migraine patients with cold and stasis obstructing meridian syndrome.</p><p><b>METHODS</b>This study was a randomized, double-blind, placebo-controlled trial. A total of 78 migraine patients with cold and stasis obstructing meridian syndrome were recruited and randomly assigned by a ratio of 2:1 into a treatment group (51 cases) and a placebo group (27 cases). Patients in the treatment group were treated with MWDG while placebo granules were applied in the control group. The treatment course lasted for 12 weeks with a follow-up of 4 weeks. The primary outcome measures included frequency and days of migraine attacks and the secondary outcome measures were analgesics consumption and visual analogue scale (VAS) scores. All outcome assessments were conducted respectively at baseline, the 4th, 8th and 12th week, and the end of follow-up.</p><p><b>RESULTS</b>In the treatment group, significant decrease in frequency of migraine attacks were observed since the 4th week and that of analgesics consumption since the 8th week (both P<0.05). While, in the placebo group, significant decrease in frequency of migraine attacks were observed since the 8th week and that of analgesics consumption since the 12th week (both P<0.05). No significant decrease in days of migraine attacks and VAS scores of migraine pain were observed in both groups. Between the two groups, there were significant differences in VAS scores and intensity of pain appeared in the 8th week (P<0.05). However, no significant differences were found in days and frequency of migraine attacks and analgesics consumption (P>0.05).</p><p><b>CONCLUSIONS</b>MWDG was probably effective in the treatment of migraine especially for alleviating pain intensity. Furthermore, MWDG could reduce the frequency of migraine attacks and analgesics consumption sooner than the placebo.</p>
