Abstract:

AIM: To investigate the clinical effect of Shenlingbaizhu powder combined with mesalazine in the treatment of ulcerative colitis (UC) and the influence of Nod-like receptor pyrin domain 3 (NLRP3) inflammasome.  METHODS: One hundred patients with UC were randomly divided into control group and observation group, fifty cases in each group. The control group was given mesalazine 1.0 g qid, while the observation group was given Shenlingbaizhu powder 6.0 g tid combined with mesalazine 1.0 g qid. The course of treatment was eight weeks. The clinical efficacy of the two groups was compared; the expression levels of NLRP3, apoptosis-associated speck-like protein containing CARD (ASC) and caspase-1mRNA were detected; The levels of C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), interleukin-1 beta (IL-1β) and interleukin-18 (IL-18) in serum was detected. RESULTS: After treatment, the total effective rate of the clinical symptoms of observation group (86%) was significantly better than that of control group (73%), the difference was statistically significant (P<0.05). The expression of NLRP3, ASC, caspase-1 mRNA in observation group (4.08±0.85, 3.75±0.91, 3.86±0.93) were more lower than those of control group (5.26±0.96, 4.66±0.95, 4.97±0.99), and the difference was statistically significant (P<0.05). The levels of CRP, ESR, IL-1 beta and IL-18 in observation group (6.74±2.45,11.63±4.58,44.27±8.58, 263.37±60.34) were more lower than those of control group (15.32±5.68,18.45±5.12,51.11±9.26, 371.18±61.25), and the difference was statistically significant (P<0.05). CONCLUSION: Shenlingbaizhu powder combined with mesalazine in the treatment of UC has good clinical curative effect, the mechanism may be related with the inhibition of NLRP3 inflammasome and inflammation.
