RESUMEN
The aberrant activation of the nucleotide-binding oligomerization domain-like receptor family pyrin domain containing 3 （NLRP3） inflammasome as an essential component of the innate system is implicated in the pathogenesis of several human inflammatory diseases. Studies have confirmed its association with digestive system diseases such as ulcerative colitis， Crohn's disease， and acute pancreatitis， suggesting that the NLRP3 inflammasome plays a role in the initiation and progression of these diseases. Based on the mechanism of NLRP3 inflammasome activation and the pathways that mediate the inflammatory response， this article introduced the relationship between the NLRP3 inflammasome and the pathogenesis of multiple digestive system diseases and the Chinese and western medical therapies. Traditional Chinese medicine （TCM） has demonstrated definite effects on the NLRP3 inflammasome-mediated digestive system diseases. Some single Chinese medicines or TCM prescriptions can treat digestive system diseases by activating or inhibiting NLRP3 inflammasome activation. NLRP3 inflammasome can receive a variety of endogenous and exogenous stimulatory signals， which can initiate， activate， and mediate inflammatory responses. The inflammasome formation and downstream inflammatory cytokines are involved in not only the inflammatory responses but also the development and progression of multiple digestive system diseases. Therefore， the NLRP3 inflammasome can serve as an ideal target for disease treatment. The future rediscovery and in-depth studies of multiple inflammasomes will shed new light on the treatment of multiple digestive system diseases.
RESUMEN
Objective To compare the effect of silver-coated dressing and general aseptic dressing on the wound healing of abdominal operation. Methods A total of 94 patients from the general surgery department of Second Affiliated Hospital of Xi'an Jiaotong University who underwent abdominal operation were divided into two groups by double blind method, 49 cases in silver-coated dressing group, and 45 cases in general aseptic dressing group. The wound healing of the two groups were observed after wound dressing change, and the wound dressing change times, the healing time, the degree of pain, the positive rate of bacterial culture and the incidence rate of scar healing were observed in the two groups. Results The patients in silver-coated dressing and general aseptic dressing group had no significant differences in gender, age, length of incision, type of incision and poor wound healing type (all P>0.05);after two wound dressings change treatment, the wound dressing change times and incision healing timeof the silver-coated dressing group was (6.52 ± 1.52) times and (16.34 ± 5.96) days, which were less than those of the general aseptic dressing group, which were (8.74 ± 2.35) times and (23.32 ± 8.32) days; and the pain severity (NRS) scored 4.13 ± 1.01, which was lower than that of general aseptic dressing group (6.54 ± 0.95), with significant difference between two groups (t=5.482, 4.704, 11.890, P < 0.05). The bacterial culture positive rates of the silver-coated dressing group was 60.00% (21/35), which was higher than that of the general aseptic dressing group, 23.33%(7/30), the difference was statistically significant (P<0.01);at the same time, the scar healing cases was 4 in the silver-coated dressing group, which was less than 11 cases in the general aseptic dressing group. The difference was statistically significant (P < 0.05). Conclusions The silver-coated wound dressing method is better than the general aseptic wound dressing, and has obvious advantages in the treatment of abdominal poor healing incision. The silver-coated wound dressing can promote the healing of incision, reduce scar healing, shorten the hospitalization time, reduce the suffering of patients.
