Abstract:
Objective To investigate the effects of thermosensitive moxibustion on psoriasis model rats'skin;To discuss its mechanism based on JAK3/STAT3 signaling pathway.Methods 5%imiquimod cream was used on the skin of rats back and along the route of the Sanjiao meridian of hand-shaoyang for psoriasis modeling.The SD rats were randomly divided into blank group,model group and treaament group.The treatment group received moxibustion therapy at"Waiguan"for 40 minutes each time for 7 consecutive days,and were divided into moxibustion group and thermosensitive moxibustion group according to sensitization state.HE staining was used to observe pathological changes in skin lesions,and ELISA was used to detect serum tumor necrosis factor(TNF)-α,interleukin(IL)-1 and IL-23 levels.Immunohistochemistry was used to detect the positive expressions of p-JAK3 and p-STAT3 in the skin lesion tissue,and RT-qPCR was used to detect the mRNA expressions of JAK3,STAT3,IL-17A and IL-17F in the skin lesion tissue.Results Compared with the normal group,model group rats were with protruding and thickened skin lesions accompanied by extensive infiltration of inflammatory cells,the contents of serum TNF-α,IL-1β and IL-23 significantly increased(P<0.01),and the positive expressions of p-JAK3 and p-STAT3 in the skin lesion tissue significantly increased(P<0.01),the mRNA expressions of JAK3,STAT3,IL-17A and IL-17F significantly increased(P<0.01).Compared with the model group,the thickness of the spinous layer in the skin lesions of rats in the thermosensitive moxibustion group was reduced,and there was no significant infiltration of inflammatory cells.The contents of serum TNF-α,IL-1β and IL-23 significantly decreased(P<0.01),and the positive expressions of p-JAK3 and p-STAT3 in skin lesion tissue significantly decreased(P<0.05,P<0.01),the mRNA expressions of JAK3,STAT3,IL-17A and IL-17F significantly decreased(P<0.05,P<0.01).Compared with the moxibustion group,the serum contents of TNF-α and IL-1β in the thermosensitive moxibustion group were significantly decreased(P<0.05,P<0.01),and the positive expression of p-JAK3 in the skin lesion tissue was significantly decreased(P<0.05).Conclusion Thermosensitive moxibustion can improve the pathological symptoms of psoriasis model rats.Its mechanism may be related to the inhibition of the JAK3/STAT3 signaling pathway,reduction of regulatory T cell-17 differentiation and secretion of pro-inflammatory cytokines.
