Objective To detect the effects of bifidobacterium or bifidobacterium cultured supernatant on the mRNA expression of tumor necrosis factor receptor-associated factor 6 (TRAF6),glycogen synthase kinase-3β (GSK-3β) and the miRNA-146a in rat small intestinal epithelial cell(IEC-6) induced by lipopolysaccharide (LPS).Methods IEC-6 in logarithmic phase were randomly divided into LPS group,cultured supernatant group and inactivated bacteria group.All the 3 groups were exposed to 5 mg/L LPS for 5 hours,and then 1 mL sterile saline was added in LPS group and culturing continued for 24 hours ; 1 mL bifidobacterium cultured supernatant was added in cultured supernatant group and culturing continued for 24 hours;1 mL inactivated bifidobacterium 1 x 1010 CFU/L added in inactivated bacteria group and continued culturing for 24 hours.The mRNA expressions of TRAF6,GSK-3 β and miRNA-146a were detected by reverse transcription-polymerase chain reaction (RT-PCR).Results The level of TRAF6,GSK-3 β of culture supematant group (0.72 ± 0.05,0.46 ± 0.14) were all lower than LPS group (1.01 ± 0.14,1.02 ± 0.25),but the level of miRNA-146a(3.05 ± 0.40) was higher than that in LPS group(1.01 ± 0.12),and there were significant differences between them (t =5.278,6.316,13.218,P =0.000).The level of GSK-3 β of inactivated bacteria group(0.59 ±0.13) was significantly lower than that in LPS group(t =4.837,P =0.000).The levels of TRAF6 and miRNA-146a of inactivated bacteria group(1.05 ±0.11,0.78 ±0.22) had no significant differences with LPS group (t =0.732,1.463,P ＞ 0.05).The level of TRAF6 of cultured supernatant group was lower than that in inactivated bacteria group,and the level of miRNA-146a was higher than that in inactivated bacteria group,and there were significant differences between 2 groups (t =6.009,14.687,P =0.000).Conclusions Bifidobacterium cultured supernatant and inactivated bacteria both have certain protective effect on the IEC-6 induced by LPS.One of the protective mechanisms of bifidobacterium cultured supernatant may be achieved by elevating the expression of miRNA-146a,and decreasing the levels of inflammation related factor TRAF6 and damage related factor GSK-3β.The protective effects of inactivated bifidobacterium may be achieved by decreasing the level of damage related factor GSK-3β.

To establish a convenient and rapid method for identification of Pseudostellariae Radix by molecular identification, the rDNA-ITS sequences of Pseudostella riaheterophylla and its adulterants had been aligned to find out specific fragment. The specific primers against the fragment were designed and the PCR amplification conditions were optimized. The fluorescence reaction of the PCR products colored by 100 x SYBR Green I was observed under UV. The concentration of reaction buffer included 5.5 μL DNA Taq polymerase premix, 10 pmol Tzs-2F and 10 pmol Tzs-2R, 20-80 ng template DNA, and plus double sterile distilled water to 25 μL. The PCR thermal profile was as follows: predenaturation at 95 degrees C for 1 min, followed by 30 cycles of denaturation at 95 degrees C for 5 seconds, primer annealing and extension at 56 degrees C for 15 seconds, then it was extension at 72 degrees C for 30 seconds. The fluorescence reaction of Pseudostellariae Radix showed green fluorescence, while adulterants had not. Extraction, amplification DNA and all steps of molecular identification could be completed successfully in 40 minutes. The approach could amplify DNA template of Pseudostellariae Radix specificity, and its product with 1 μL 100 x SYBR Green I could engender green fluorescence under UV. The method was simple and accurate, so it could be used for identification of Chinese traditional medicine.
