摘要Objective:To investigate effect of bifidobacterium triple viable powder on inflammatory factors and T lymphocyte subsets in patients with ulcerative colitis.Method:80 patients with ulcerative colitis were selected and divided into observation group and control group, 40 cases in each group. The control group was given dietary guide, mesalazine, vitamin C and other comprehensive treatment; The observation group was given bifidobacterium triple viable powder adjuvant therapy on the basis of conventional treatment. The level of IL-6, CRP, TNF-α and T lymphocyte subsets in the two groups was compared before treatment (T0), after treatment for 1 month (T1), after treatment for 3 months (T2).Results: (1) The levels of IL-6, CRP and TNF-α at T1 serum were lower than those in T0 in both groups, the levels of serum IL-6, CRP and TNF-α at T2 were lower than those of T0 and T1, these three levels in different time points were statistical significant difference; The levels of serum IL-6, CRP and TNF-α in observation group at T1 and T2 were significantly lower than those in control group, there was significant difference in both groups; (2)The levels of CD3+, CD4+, CD4+/CD8+ at T1 were higher than T0 in two groups, The levels of CD3+, CD4+, CD4+/CD8+ at T2 were superior than at T0 and T1. The level of CD8+ at T1 was below at T0, The level of CD8+ at T2 was inferior than those in T0 and T1, The levels of CD3+,CD4+,CD8+ and CD4+/CD8+ at different time points were significant difference. The levels of CD3+, CD4+, CD4+ /CD8+ in the observation group were significantly higher than those in the control group T1 and T2, CD8+ level was significantly lower than that in the control group at T1 and T2, difference between the two groups was statistically significant.Conclusion:Bifidobacterium triple viable powder adjuvant treatment ulcerative colitis was good for inhibiting body inflammatory response and improve immune function.
