Objective To investigate the mechanism of action of Huzhang Qingmai decoction (HZQMY) on the improvement of cognitive function in mice with chronic cerebral ischemia from the perspective of intestinal flora. Methods A mouse model of chronic cerebral ischemia was established by placing microcoils around the bilateral common carotid arteries to induce bilateral carotid artery stenosis (BCAS). After 12 weeks of intragastric administration, the cognitive function of the mice was measured by the Morris water maze; the myelin damage was analyzed by LFB staining; The contents of the cecum of the mice in each group were extracted and analyzed by 16S rRNA sequencing. Results The results of the water maze experiment showed that the mice in the HZQMY group had a significantly shorter escape latency, increased the number of crossings platform and the percentage of target quadrants. LFB staining showed that the white matter damage in the model group was severe; the white matter damage in the HZQMY group was milder. The results of 16S rRNA sequencing showed that compared with the model group, the abundance of Verrucomicrobiota, Akkermansia, and ErysiPelatoclostridium capsulatum in the intestinal flora in HZQMY group was significantly reduced (P<0.05), while the abundances of Eubacterium_xylanoPhilum and Allobaculum were significantly increased (P<0.05). Conclusion The protective effect of HZQMY, which has the effect of improving cognitive function in mice with chronic cerebral ischemia, may be related to the regulation of intestinal flora in mice with chronic cerebral ischemia.

Objective To explore the mechanism of motherwort in the treatment of nerve injury. Methods The active components of motherwort were obtained by searching TCMSP and BATMAN-TCM databases. The action targets of candidate compounds were collected and predicted from TCMSP and SwissTargetPrediction (STP) databases. The target genes corresponding to the active components of motherwort were obtained by using the standardized database of disease targets (Uniprot). The potential targets of motherwort in the treatment of nerve injury were obtained by mapping the disease genes of nerve injury with the three databases of Genecards, DisGenet and OMIM. The network topology analysis software Cytoscape 3.6.0 was used to construct the action target network of motherwort active components. The protein interaction platform database (STRING) was used to construct the interaction relationship between action targets. The target protein interaction (PPI) network was constructed by introducing Cytoscape 3.6.0 software. Through STRING database, GO enrichment analysis and KEGG pathway enrichment analysis were carried out to analyze the target points of motherwort in the treatment of nerve injury. Results 19 active components were screened from motherwort, involving 654 action targets, including 426 action targets related to nerve injury and 6 key targets. These target genes were mainly involved in biological regulation, oxidative stress response and cell communication and other biological processes. Molecular functions were mainly related to protein binding, ion binding and catalytic reduction. They were enriched outside the cell membrane. Its mechanism was related to signal pathways such as MAPK, Toll-like receptor, PI3K-Akt, TNF, IL-17, and apoptosis. ConclusionThe active components of motherwort may play a protective role on nerve injury through antii nflammation, anti-apoptosis and promoting cell growth. [ABSTRACT FROM AUTHOR]

Physiological experiment is a traditional experimental course, with the development of scientific research, the classic experimental curriculum also needs to be reformed to adapt to changes in the times. This reform requires not only teachers to conduct in-depth thinking on the curriculum , but also the participation of students. The questionnaire survey is a way to collect students feedback, and can make students participate in teaching reform and improvement of teaching quality. This questionnaire survey was carried in Peking University physiology experiment course from 2012, and so far seven semester data were accumulated. The areas that need to be improved in the course were found through analysis of the survey results, and some problems have been solved. These practices have prompted us to continue to improve the questionnaire survey methods to promote the continuous progress of experimental teaching. [ABSTRACT FROM AUTHOR]
