OBJECTIVETo observe the effect of Angong Niuhuang Pill (ANP) on Thl/Th2 in cerebral infarction patients and to explore the mechanism of phlegm-heat obstructing orifices.METHODSRe- cruited were 30 cerebral infarction patients of phlegm-heat obstructing orifices syndrome (PHOOS) both in China and Indonesia. They were assigned to 4 groups according to the use of ANP, the Chinese treatment group, the Indonesia treatment group, the Chinese control group, and the Indonesia control group. Patients in the two control groups received conventional treatment, while those in the two treatment group additionally took ANP for 30 successive days. Their adverse reactions were observe, and levels of INF-γ and IL-4 were detected.RESULTSThe INF-γ level and the INF-γ/IL-4 ratio significantly decreased, and the IL-4 level increased after treatment in the four groups with statistical difference (P < 0.05). Compared with the control group after treatment in the same country, the INF-γ level and the INF-γ/IL-4 ratio were lower, and the IL-4 level was higher in the two treatment groups (P < 0.05). Compared with the two Chinese groups, the INF-γ level and the INF-γ/IL-4 ratio were higher, and the IL-4 level was lower in the two Indonesian groups (P < 0.05). There was no statistical difference in the post-treatment indices between the two treatment groups.CONCLUSIONSANP had moderating effect on Th1/Th2 in cerebral infarction pa- tients. Cerebral infarction patients of PHOOS might exist certain relation with Th1/Th2.

OBJECTIVETo identify Tongren Dahuoluo pills and Tongren Niuhuangqingxin pills respectively by analysis of IR fingerprint.METHODBoth drugs were extracted with hexane, ethylether and butanone respectively and then the obtained extracts were measured with the ET-IR spectrometer.RESULTBy analyzing IR fingerprint of 25 batches of Tongren Dahuoluo pills and 27 batches of Tongren Niuhuangqingxin pills, we found that different batches of the same drug hadstabile and repeatable fingerprint.CONCLUSIONBy using IR fingerprint, either Tongren Dahuoluo pills or Tongren Niuhuangqingxin pills can be exactly identified. It provides a rapid method for drug identification and quality control.

Angong Niuhuang Pill ameliorates cerebral ischemia/reperfusion injury in mice partly by restoring gut microbiota dysbiosis

Angong Niuhuang Pill (ANP) is a famous traditional Chinese patent medicine and is used for treating ischemic or hemorrhagic stroke for centuries. However, the mechanism of action of ANP in stroke treatment has rarely been reported. With increasing evidence for a mechanistic link between acute ischemic stroke and gut microbiota alterations, this study aimed to determine the mechanism of action of ANP in treating acute ischemic stroke from the perspective of the gut microbiota. A mouse model of acute ischemic stroke by middle cerebral artery occlusion (MCAO) was established, and 16S ribosomal RNA (rRNA) gene sequencing and metabolomic analysis were performed on the cecal content samples collected from the sham, model, and ANP-treated MCAO mice. The results showed that ANP significantly ameliorated cerebral infarct volume, improved neurological deficits, and reduced histopathological injuries in the ipsilateral ischemic cortex, hippocampus, and striatum. The latter effects included inhibition of neuronal death, increased Nissl bodies, and decreased cell apoptosis. Moreover, ANP reversed gut microbiota dysbiosis by modulating the abundance of bacteria whose effects may mitigate MCAO damage, such as the phyla Bacteroidetes and Firmicutes, the families Lachnospiraceae and Prevotellaceae, and the genera Alloprevotella and Roseburia. Microbial metabolites related to inflammation and neuroprotection, such as prostaglandin I2 and uridine, were also regulated by ANP treatment. Uridine, guanosine, and inosine might be potential neuromodulators produced by the gut microbiota in the ANP-treated group. Spearman correlation analysis revealed that these metabolites were intimately related to certain genera, including Alloprevotella, Lachnoclostridium, Enterorhabdus, Roseburia, Lachnospiraceae_UCG-006, and Colidextribacter. Our results demonstrated that alleviating gut microbiota dysbiosis is one of the mechanisms by which ANP protects against ischemic stroke and suggest that targeting Alloprevotella, Lachnoclostridium, Enterorhabdus, Roseburia, Lachnospiraceae_UCG-006, and Colidextribacter might be a potential anti-stroke therapy.
