益生菌结合蒙脱石散对轮状病毒感染乳鼠肠道黏膜、肠道微生物功能相关基因表达的影响
Effects of probiotics combined with montmorillonite powder on intestinal mucosa and expressions of intestinal microorganism function-related genes in neonatal rats with rotavirus infection
摘要
Abstract
Objective To analyze the effects of probiotics combined with montmorillonite powder on intestinal mucosa and expressions of intestinal microorganism function-related genes in neonatal rats with rotavirus(RV)infection.Methods RV infection model was established by intragastric administration of SA11 strain rotavirus.Forty-eight suckling rats were randomly divided into normal group(0.9％NaCl),model group(0.9％NaCl),experimental group(0.06 g·mL-1 montmorillonite powder)and combined group(0.06 g·mL-1 montmorillonite powder+6.5 × 107 CFU·mL-1 Saccharomyces cerevisiae powder)with 12 rats in each group.The feces were collected for evaluation.The levels of serum tumor necrosis factor-a(TNF-a),interleukin-1 β(IL-1 β)and IL-17 were detected by enzyme-linked immunosorbent assay,the levels of aquaporin(AQP)in intestinal tissues was detected by real-time fluorescence quantitative polymerase chain reaction,and the counts of Bifidobacteria and Escherichia coli in feces were detected by bacterial 16srDNA fluorescence quantitative polymerase chain reaction.Results The feces scores in normal,model,experimental and combined groups were(1.01±0.10),(2.97±0.08),(2.84±0.03)and(2.77±0.03)points;TNF-α levels were(132.54±14.63),(185.66±19.64),(165.25±17.63)and(149.95±15.76)pg·mL-1;IL-1β levels were(172.32±18.68),(265.34±27.72),(202.34±21.34)and(186.24±19.46)pg·mL-1;IL-17 levels were(118.62±12.44),(173.24±18.25),(152.32±16.72)and(122.54±13.58)pg·mL-1;Bifidobacteria counts were(6.35±0.64),(4.31±0.44),(4.93±0.50)and(5.34±0.54)CFU·g-1;Escherichia coli counts were(6.14±0.62),(8.78±0.88),(8.46±0.85)and(8.12±0.83)CFU·g-1;mRNA levels of AQP2 were 1.02±0.05,0.72±0.07,0.89±0.08 and 1.21±0.12;mRNA expression levels of AQP4 were 1.04±0.07,0.42±0.05,0.78±0.08 and 1.19±0.12;mRNA expression levels ofAQP8 were 1.00±0.06,0.63±0.06,0.91±0.09 and 1.30±0.13,respectively.There were significant differences of above indexes between the model group with the normal,experimental and combined groups(all P＜0.05).Conclusion Montmorillonite powder combined with probiotics can improve fecal properties,reduce serum inflammatory factors and correct intestinal flora disorders in neonatal rats with RV infection,which may be related to improving the expressions of intestinal A QP2,AQP4 and AQP8.关键词
