Objective To analyze the correlation of cholecystectomy and changes in intestinal microbiota composition and function by observing functional characteristics of differential microbial communities.Methods A cross-sectional study was conducted on the patients(PC group,n=73)undergoing cholecystectomy in our hospital from 2020 to 2021.Another 56 healthy age-and gender-matched individuals(HC group)without a history of cholecystectomy were subjected and served as the control group.Fecal specimens were collected from the 2 groups.16S rRNA sequencing analysis was performed to examine the changes in composition and function of intestinal microbiota.Results There were no statistical differences between the 2 groups in baseline indicators,such as gender,age,BMI,smoking and drinking history,blood pressure,heart rate,and comorbidities,but significant difference was observed in total bilirubin(TBIL)between them(P<0.01).Alpha diversity analysis showed no significant difference in Chao1,Shannon,and Simpson indices between the 2 groups.Beta diversity analysis using the Bray-Curtis distance algorithm revealed a significant difference between the 2 groups at the class and genus levels(P<0.05).The analysis of microbiota relative abundance using LEFSE showed that Enterobacteriaceae,Lactobacillales,Citrobacter,Megasphaera,Lactobacillus,Enterococcus,Akkermansia,Streptococcus,Klebsiella,and Ruminococcus_gnavus were up-regulated in the PC group,and Lachnospiraceae,Sutterellaceae,Lachnospirales,Lachnospira,and Sutterella were down-regulated.Kyoto Encyclopedia of Genes and Genomes(KEGG)functional prediction analysis indicated that significant differences were seen between the 2 groups in metabolic pathways,including ascorbic acid(vitamin C)metabolism and aldonic acid metabolism(P<0.05),tricarboxylic acid cycle(TCA cycle)(P<0.05),glutathione metabolism(P<0.05),glutamic acid metabolism(P<0.05),secondary bile acid metabolism(P<0.05),and pentose phosphate pathway(P<0.01).Conclusion Cholecystectomy is closely associated with the structural alterations in the composition of intestinal microbiota.Variations in microbiota composition and function may induce perturbations in TCA cycle and glutathione metabolism,glutamate metabolism,secondary bile acid metabolism,and pentose phosphate pathways.

The chemical composition of Paeoniae Radix Alba(PRA) is complex, with primary secondary metabolites including monoterpenoids, tannins, triterpenoids, and flavonoids. In previous studies on the material basis of PRA, it was found that, in addition to the widely studied characteristic monoterpene glycosides, tannic acid components also play an important role in the efficacy of PRA. However, their pharmacological effects have not been thoroughly investigated. This paper reviews the tannic acid components in PRA, including pentagaloyl glucose(PGG), tetragaloyl glucose(TGG), trigaloyl glucose(TriGG), and gallic acid, along with their structures, properties, and characteristics to provide a detailed discussion of their pharmacological activities and related mechanisms, aiming to offer a theoretical basis for the material basis research and clinical application of PRA.

ObjectiveTo explore the mechanism of Huanglian Ejiaotang in intervening in insomnia based on 5-hydroxytryptamine (5-HT) system and gut microbiota. MethodFifty-five SPF-grade SD rats were randomly divided into normal group, model group, low-, medium-, and high-dose Huanglian Ejiaotang groups (1.925, 3.85, and 7.7 g·kg-1), and Estazolam group (0.1 mg·kg-1). Except for those in the normal group, the rats in the other five groups were subjected to sleep deprivation on a narrow platform for 12 hours daily for 21 consecutive days. After 14 days of drug intervention, the sleep, exploratory behavior, and depressive-like behavior of the rats were assessed using the pentobarbital sodium sleep synergistic test, the open field test, and the sugar preference test, respectively. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of 5-HT, 5-hydroxyindoleacetic acid (5-HIAA), tryptophan hydroxylase (TPH), and monoamine oxidase-A (MAO-A). Real-time polymerase chain reaction (Real-time PCR) was used to measure the mRNA expression of the 5-HT1A receptor (5-HT1AR) and 5-HT2A receptor (5-HT2AR). Differences in gut microbiota among the groups were assessed using 16S rRNA sequencing, and the correlation between the 5-HT system and microbiota was revealed using redundancy analysis. ResultCompared with the normal group, the model group showed a prolonged sleep latency (P<0.05), reduced sleep maintenance (P<0.01), decreased central area activity time in the open field (P<0.01), and reduced sugar preference rate (P<0.05). Moreover, the model group also showed decreased levels of 5-HT, 5-HIAA, TPH, and MAO-A (P<0.01), decreased 5-HIAA/5-HT ratio (P<0.01), downregulated mRNA expression of 5-HT1AR (P<0.01), and upregulated mRNA expression of 5-HT2AR (P<0.05). The proportion of Firmicutes decreased, while that of Bacteroidetes increased, leading to a decreased Firmicutes/Bacteroidetes (F/B) ratio (P<0.05). Compared with the model group, the high-dose Huanglian Ejiaotang group exhibited a shortened sleep latency (P<0.01), and increased sleep maintenance (P<0.01). The low-dose Huanglian Ejiaotang group showed increased central area activity time (P<0.01) and an increased sugar preference rate (P<0.05). The high-dose Huanglian Ejiaotang group exhibited increased levels of 5-HT, 5-HIAA, TPH, and MAO-A (P<0.01), increased 5-HIAA/5-HT ratio (P<0.05), upregulated mRNA expression of 5-HT1AR (P<0.01), and downregulated mRNA expression of 5-HT2AR (P<0.05). The low-dose Huanglian Ejiaotang group displayed an increased proportion of Firmicutes and a decreased proportion of Bacteroidetes, resulting in an increased F/B ratio. At the phylum level, 5-HT, 5-HIAA, and MAO-A were positively correlated with Firmicutes and negatively correlated with Bacteroidetes. At the genus level, 5-HT, 5-HIAA, TPH, and MAO-A were negatively correlated with Prevotella and Lactobacillus and positively correlated with Blautia and Bacteroides. ConclusionHuanglian Ejiaotang can improve sleep deprivation-induced insomnia and depressive-like behavior by regulating the activity of the 5-HT system and the composition of gut microbiota.
