Abstract:
Objectives To compare the differences in intestinal phylum firmicutes between elderly patients with type 2 diabetes (T2DM)and the healthy elder people.Methods 37 elderly patients with T2DM and 69 healthy controls in Shaoxin city were recruited.DNA of phylum firmicutes from fecal samples was extracted.The real-time quantitative PCR was used with special primers for bacterial genus including Faecalibacterium prausnitzii,Eubacterium rectale,Clostridium leptum,and Peptostrepyococc.The differences in content of different bacteria between two groups were analyzed and compared.Results In healthy elderly group versus the elder patient with T2DM,the contents of intestinal phylum firmicutes were[(6.22±1.41) × 107 versus(5.41± 1.40) × 107,t=2.83,P=0.006] in Eubacterium rectale,[(7.46 ± 0.98) × 107 versus (6.96 ± 1.40) × 107),t =2.13,P =0.036] in Faecali bacterium prausnitzii,[(7.89±0.89) × 107 versus(7.46±1.11) × 107,t=2.15,P=0.034]in Clostridium leptum,and[(4.86 ± 1.33) × 107 versus (4.21 ± 1.24) × 107,t=2.45,P =0.016] in Peptostrepyococc,which showed that the contents of intestinal phylum firmicutes were less in T2DM group than in healthy elderly group.Conclusions There are some differences in intestinal flora between the elderly patients with T2DM and healthy people.These intestinal flora may play an important role in the development of T2DM.This study may provide new evidences for probiotic treatment of T2DM.
