摘要:
The aim was to investigate the effect of lily bulbs on the microecological characteristics of intestinal microbiota and enzyme activities in normal mice. Thirty SPF Kunming mice were randomly divided into the control group, Lilium lancifolium (LL) group and Lilium davidii var. unicolor (LDU) group. Mice of the latter two groups were given 0.15g·mL−1 lily bulb solution, respectively, by gavage twice a day, while the control group was given the same volume of sterilized water. After 49days, intestinal contents and mucosa of all mice were collected and the characteristics of intestinal microbiota and enzyme activities were analyzed. Results showed that the number of Lactobacillus spp. and Bifidobacteria spp. in the LL group was significantly higher than that in the control group (t = 2.68 × 107, P = 0.000; t = 5.96 × 107; P = 0.000) and the LDU group (t = 6.12 × 107, P = 0.000; t = 2.71 × 107, P = 0.000), while the number of total bacteria was significantly lower (P = 0.040). Microbial activity in intestinal contents and mucosa of the LDU group (t = 0.43, P = 0.001; t = 0.69, P = 0.000) decreased, and microbial activity in intestinal mucosa of the LL group decreased significantly (t = 0.89, P = 0.000) but increased significantly in intestinal contents of the LL group (t = 0.81, P = 0.000). The activities of amylase (t = 455.73, P = 0.000; t = 206.56, P = 0.000) and protease (t = 52.32, P = 0.000) increased but the activities of lactase (t = 443.51, P = 0.000; t = 15.71, P = 0.000) and sucrase (t = 5.82, P = 0.000; t = 366.82, P = 0.000) decreased significantly in contents from the LL group and LDU group. Except for the sucrase activity, enzyme activities in mucosa of the LL group were completely opposite to those in contents (t = 44.15, P = 0.000; t = 1.25, P = 0.007; t = 14.64, P = 0.011). In conclusion, dietary lily bulbs increased intestinal contents amylase activities and mucosa lactase activity significantly. Lily bulbs, especially Lilium lancifolium, can promote the growth of Lactobacillus spp. and Bifidobacteria spp., and inhibit the growth of total bacteria in the intestines of normal mice. Lilium lancifolium bulbs have the potential to be a functional food. © 2021, King Abdulaziz City for Science and Technology.

摘要:
Background: Helicobacter pylori–associated gastritis (HPAG) is a common digestive system disease that its therapeutic goal is to eradicate Helicobacter pylori. However, due to the widespread use of antibiotics, problems for example, antibiotic resistance, reinfection, and gastrointestinal side effects have emerged. The solution of above problems provides a broad space for traditional Chinese medicine (TCM) to exert its remarkable advantages on the treatment of HPAG. Methods: Extensive database retrieval using platforms not limited to but including Web of Science, SpringerLink, ScienceDirect, Google Scholar, China National Knowledge Infrastructure, Wanfang, and VIP database was performed using keywords such as “Helicobacter pylori-associated gastritis” or “HPAG” or “Helicobacter pylori” or “H. pylori” or “gastritis” and “traditional Chinese medicine” or “TCM” or “herbs” or “Chinese herbal medicine”. In addition, related books, PhD, and master's dissertations were also researched to provide a comprehensive review. Results: This review mainly introduces the clinical efficacy of TCM formulas for HPAG, as well as active ingredient and pharmacological mechanisms of herbs. What's more, this review puts forward potential prospects for future research. Conclusion: These research works have shown the therapeutic benefits of TCM in the treatment of HPAG. The development of TCM with more specific functions and practical data will not only become a significant trend in the world market but also have an irreplaceable role in the future treatment of HPAG. More continued researches should be undertaken in the future. © 2021 John Wiley & Sons Ltd

摘要:
代谢性疾病是指葡萄糖、蛋白质及脂质在体内代谢异常引起的一类疾病.越来越多的证据支持肠道菌群失调与代谢性疾病具有重要的相关性.具体而言,肠道菌群失调可能破坏肠道屏障功能,诱发内毒素血症、胆汁酸代谢紊乱和全身慢性低度炎症,促进代谢性疾病进展及并发症发生.随着代谢性疾病病情进展,肠道内环境改变以及药物、饮食等影响又反过来加重肠道菌群失调,最终引起预后不良.这凸显了通过调节肠道菌群结构来开发防治代谢性疾病治疗策略的可能性.益生菌、益生元和合生元疗法、粪菌移植、中医药等可通过维持肠道菌群平衡、对抗有害菌群产物,从而治疗代谢性疾病.本文从代谢性疾病肠道菌群变化、肠道菌群影响代谢性疾病的可能机制、肠道菌群在代谢性疾病治疗中的应用等方面进行综述,以期为以肠道菌群为靶点的代谢性疾病的诊断防治研究提供借鉴.

摘要:
目的探讨痛泻要方对肝气乘脾泄泻小鼠肠道微生物活度的影响,为痛泻要方通过调节肠道微生物治疗肝气乘脾泄泻提供实验基础和理论依据。方法将25只SPF级雄性昆明小鼠随机分为正常组10只和模型组15只,造模成功后,随机选取正常组和模型组动物各5只,在无菌环境下提取肠道内容物和肠黏膜,剩余模型动物随机分为自然恢复组和治疗组各5只,治疗成功后处死各组动物提取肠道内容物和肠黏膜。用荧光素二乙酸法测定各样品中微生物活度。结果肝气乘脾泄泻造模小鼠肠道内容物微生物活度高于正常组,与正常组相比差异有统计学意义(P=0.01),而模型组小鼠肠黏膜微生物活度降低,与正常组相比差异有统计学意义(P=0.01)。痛泻要方治疗组和自然恢复组小鼠肠道内容物微生物活度均降低,与正常组相比差异无统计学意义(P>0.05),治疗组和自然恢复组小鼠的肠黏膜前段和后段均与正常组差异有统计学意义(P=0.001),肠黏膜中段自然恢复组与正常组差异有统计学意义(P=0.043),而治疗组与正常组没有差异。结论肝气乘脾泄泻造模使肠道内容物微生物活度增加,而使肠黏膜微生物活度降低。痛泻要方能够使肝气乘脾泄泻小鼠肠道内容物中微生物活度降低,恢复至正常水平,增加肠黏膜中段微生物活度,对肠黏膜后段微生物活度增加作用更显著。

摘要:
Although reports have provided evidence that diarrhea caused by Folium sennae can result in intestinal microbiota diversity disorder, the intestinal bacterial characteristic and specific mechanism are still unknown. The objective of our study was to investigate the mechanism of diarrhea caused by Folium sennae, which was associated with intestinal bacterial characteristic reshaping and metabolic abnormality. For the intervention of Folium sennae extracts, Chao1 index and Shannon index were statistical decreased. The Beta diversity clusters of mice interfered by Folium sennae extracts were distinctly separated from control group. Combining PPI network analysis, cytochrome P450 enzymes metabolism was the main signaling pathway of diarrhea caused by Folium sennae. Moreover, 10 bacterial flora communities had statistical significant difference with Folium sennae intervention: the abundance of Paraprevotella, Streptococcus, Epulopiscium, Sutterella and Mycoplasma increased significantly; and the abundance of Adlercreutzia, Lactobacillus, Dehalobacterium, Dorea and Oscillospira reduced significantly. Seven of the 10 intestinal microbiota communities were related to the synthesis of tryptophan derivatives, which affected the transformation of aminotryptophan into L-tryptophan, leading to abnormal tryptophan metabolism in the host. Folium sennae targeted cytochrome P450 3A4 to alter intestinal bacterial characteristic and intervene the tryptophan metabolism of intestinal microbiota, such as Streptococcus, Sutterella and Dorea, which could be the intestinal microecological mechanism of diarrhea caused by Folium sennae extracts.

摘要:
为建立小鼠肝气乘脾泄泻的造模方法,并通过痛泻要方对其疗效进行验证.采用番泻叶加束缚夹尾法制备肝气乘脾泄泻小鼠模型,运用痛泻要方进行治疗,以主观和客观指标进行综合评价.结果显示,番泻叶-束缚夹尾使模型小鼠出现情绪亢奋,腹泻程度严重,进食量减少,体重增长幅度下降,毛发变暗、枯黄,同时甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、5-羟色胺(5-HT)含量升高(P > 0.05),D-木糖含量下降(P < 0.05),符合脾虚证诊断标准,同时出现肠推进率增高(P < 0.05)、胃残留率降低(P > 0.05)等小肠功能亢进的表现.经痛泻要方干预后小鼠一般行为接近正常组,腹泻症状明显消失,总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)(P < 0.05)、TG、LDL-C相对正常组含量下降(P > 0.05),模型组相对自然恢复组的5-HT含量减少(P < 0.01),而D-木糖含量出现一定程度的升高(P > 0.05),痛泻要方能调节模型小鼠的胃肠运动,降低其肠推进率,升高胃残留率(P > 0.05).本研究表明通过番泻叶-束缚夹尾法上午灌胃番泻叶造成小鼠脾虚泄泻,下午离心管束缚夹尾模拟小鼠肝旺状态,连续造模7 d,可以建立小鼠肝气乘脾泄泻模型,痛泻要方干预3 d可以治愈,5-HT增高、D-木糖降低、胃动力减缓等能作为小鼠肝气乘脾泄泻的评价指标;结果可为小鼠肝气乘脾泄泻模型的建立提供可靠的实验依据.

人类疾病动物模型在认识生命科学客观规律中扮演着重要的角色,中医动物模型建立是中医药研究现代化进程的重要推动力。食滞胃肠泄泻是中医泄泻当中常见的一种类型,多因饮食不节、暴饮暴食而致宿食内停、阻滞肠胃。在中医基础理论指导下,建立符合中医病因病机的食滞胃肠泄泻动物模型是开展该病基础研究工作的重要载体。分析食滞胃肠相关动物模型研究现状、食滞胃肠泄泻的中医认识,结合食滞、脾虚与泄泻三者之间的关系,为食滞胃肠泄泻动物模型的制备提供思路。

摘要:
The aim was to investigate the combined effect of Debaryomyces hansenii and Qiweibaizhu powder (QWBZP) on the bacterial diversity of the intestinal mucosa of antibiotic-associated diarrhea (AAD) mice, for the potential treatment of diarrhea, especially which is induced by administration of antibiotics. Eighteen (18) mice were randomly assigned to three equal groups of six mice, namely Normal (mn group), Placebo control (mm group) and D. hansenii and QWBZP (DQ) treatment (mdq group). Mice were gavaged with a solution (23.33mL·kg−1·day−1) consisting of gentamicin and cefradine to establish AAD. The DQ treatment group was gavaged with DQ for 4days, and sterile water was used as a placebo control. The metagenome DNA of the intestinal mucosal microbiota was extracted, and the 16S rRNA gene was sequenced. Analysis showed that there were 288 OTUs for the normal group, 443 for the placebo control group, and 229 for the DQ treatment group. Phylogenetically, the gut microbiota of the DQ treatment group and the normal group were closer to each other than to the placebo control group. Both the DQ and placebo-treated groups included Stenotrophomonas, Robinsoniella, Bacteroidales S24-7 group norank, Citrobacter, and Glutamicibacter, but their abundances were significantly higher in the DQ treatment group than in the placebo control group. This suggested that the combined use of D. hansenii and QWBZP overcame the influence of dysbacteriosis and could lead to the recovery of intestinal mucosal microbiota homeostasis. This positive effect is likely related to short-chain fatty acid (SCFA)-producing bacteria, such as members of Micrococcaceae, Lachnospiraceae, and Bacteroidales S24-7 group, which could play beneficial roles in protecting the mucosal barrier and stimulating the immune response in mice. © 2020, King Abdulaziz City for Science and Technology.

摘要:
Antibiotic-associated diarrhea (AAD), defined as diarrhea that occurs in association with the administration of antibiotics and without another clear etiology, is one of the most common adverse drug events of antibiotics therapy. We established a diarrhea model induced by gentamycin and cefradine to investigate the microbiota characteristics in the intestinal lumen of mice with AAD and provide insights into noteworthy bacteria related to gentamicin and cefradine-associated diarrhea. The number of OTUs in the model group and the normal group was 983 and 2107, respectively, and 872 identical OTUs were shared between two groups. Species richness and species diversity of intestinal microbe were altered by antibiotics administration. PCoA showed a clear separation between AAD and health control. The dominant phyla of AAD mice were Firmicutes (52.63%) and Proteobacteria (46.37%). Among the genus with top 20 abundance, the relative abundance of 7 genera, Ruminococcus, Blautia, Enterococcus, Eubacterium, Clostridium, Coprococcus, and Aerococcus, were enriched in the model group. Based upon the LEfSe analysis, Enterococcus, Eubacterium, Ruminococcus, and Blautia were identified as potential biomarkers for AAD. The bacterial diversity of the intestinal lumen was diminished after gentamicin and cefradine administration. The alterations in the abundance and composition of gut microbiota further led to the dysfunction of gut microbiota. More specifically, gentamicin and cefradine significantly increased the abundance of the opportunistic pathogens, of which Enterococcus and Clostridium were the most prominent and most worthy of attention.
