OBJECTIVE To investigate the improvement effects of 3,5,6,7,8,3′,4′-heptamethoxyflavone (HMF) of Fructus Aurantii on rats with damp blockage of the middle energizer. METHODS The rats were randomly divided into normal group, model group, positive control group (Raceanisodamine tablet, 1 mg/kg), HMF low-dose, medium-dose and high-dose groups (0.3, 0.6, 0.9 mg/kg), with 7 rats in each group. Except for the normal group, the other groups were modeled by internal and external composite factors. After successful modeling, the rats in each group were given the corresponding drug or normal saline, once a day, for 14 days. The general behavioral states such as dietary intake, water intake and mental state of the rats were observed, and the fecal water content rate and saliva flow rate were measured. Hematoxylin-eosin (HE) staining was used to observe the pathological and morphology in gastric and small intestinal tissues of rats. The plasma content of aldosterone was detected, and the expression of aquaporins (AQP3) in the gastric tissue of rats was determined. RESULTS Compared with the normal group, the dietary intake and water intake of the model group rats were significantly decreased (P<0.01), the fecal water content rate, salivary flow rate, plasma content of aldosterone and the expression of AQP3 in gastric tissue were increased significantly (P<0.01). Gastric tissue injury invaded the mucosal muscle layer, resulting in mucosal muscle layer rupture; pathological and morphological changes such as small intestinal villous erosion and glandular structure destruction were observed in the small intestine. Compared with the model group, the dietary intake and water intake of rats were increased in HMF groups; fecal water content rate, salivary flow rate, plasma content of aldosterone, the expression of AQP3 in gastric tissue were decreased, most of the above differences were statistically significant (P<0.05 or P<0.01). The pathological and morphological changes in the gastric and small intestine tissues of rats had been improved to varying degrees. CONCLUSIONS HMF of Fructus Aurantii with dry property HMF could improve the symptoms of rats with damp blockage of middle energizer, the mechanism of which may be associated with reducing the content of plasma aldosterone and down-regulating the expression of gastric AQP3.

The human oral microbiome harbors one of the most diverse microbial communities in the human body, playing critical roles in oral and systemic health. Recent technological innovations are propelling the characterization and manipulation of oral microbiota. High-throughput sequencing enables comprehensive taxonomic and functional profiling of oral microbiomes. New long-read platforms improve genome assembly from complex samples. Single-cell genomics provides insights into uncultured taxa. Advanced imaging modalities including fluorescence, mass spectrometry, and Raman spectroscopy have enabled the visualization of the spatial organization and interactions of oral microbes with increasing resolution. Fluorescence techniques link phylogenetic identity with localization. Mass spectrometry imaging reveals metabolic niches and activities while Raman spectroscopy generates rapid biomolecular fingerprints for classification. Culturomics facilitates the isolation and cultivation of novel fastidious oral taxa using high-throughput approaches. Ongoing integration of these technologies holds the promise of transforming our understanding of oral microbiome assembly, gene expression, metabolites, microenvironments, virulence mechanisms, and microbe-host interfaces in the context of health and disease. However, significant knowledge gaps persist regarding community origins, developmental trajectories, homeostasis versus dysbiosis triggers, functional biomarkers, and strategies to deliberately reshape the oral microbiome for therapeutic benefit. The convergence of sequencing, imaging, cultureomics, synthetic systems, and biomimetic models will provide unprecedented insights into the oral microbiome and offer opportunities to predict, prevent, diagnose, and treat associated oral diseases.
