Abstract:
Objective To investigate the therapeutic efficacy of Qingxin Yunpi Formula(QXYPF)in a mouse model of food allergy(FA)-associated atopic dermatitis(AD)induced by 2,4-dinitrochlorobenzene(DNCB)and ovalbumin(OVA).Methods Male BALB/c mice were randomly divided into six groups(n=10 per group):control,AD,model,QXYPF low-dose(QXYPF-L),QXYPF high-dose(QXYPF-H),and prednisone(PNS).Except for the control and AD groups,FA-AD was induced by epicutaneous application of DNCB on the dorsum combined with intraperitoneal OVA injection;the AD group received DNCB application only.Post-modeling assessments included:clinical evaluation of dorsal lesions,dermatitis severity scoring,quantification of scratching behavior,histopathological examination of skin sections to determine epidermal thickness and mast cell infiltration,enzyme-linked immunosorbent assay(ELISA)measurement of serum OVA-specific IgE(OVA-sIgE)levels,and of T-helper(Th)2 cytokines(IL-4,IL-5)and Th1 cytokine(IFN-γ),and immunohistochemical analysis of IL-4,IL-5,and IFN-γ in lesioned skin tissues.Results Compared with the control group,mice in the model groups exhibited more severe dorsal skin lesions,increased dermatitis scores and scratching frequencies(P＜0.05).The model group showed significantly thickened dorsal epidermis(P＜0.05),acanthosis,and noticeable inflammatory cell infiltration in the dermis.Serum levels of OVA-sIgE,IL-4,and IL-5 were elevated(P＜0.05),while IFN-γ levels were decreased in both AD and model groups(P＜0.05).Additionally,protein expression of IL-4 and IL-5 in dorsal lesional tissues was increased in the model group(P＜0.05),whereas IFN-γ protein levels were reduced in both AD and model groups(P＜0.05).In comparison with the model group,all treatment groups demonstrated improved dorsal skin lesions,significantly reduced dermatitis scores and scratching frequencies(P＜0.05),markedly alleviated epidermal thickening(P＜0.05),improved acanthosis,and reduced inflammatory infiltration in the dermis.Serum OVA-sIgE levels were decreased(P＜0.05),along with reduced serum IL-4 and IL-5 levels and increased IFN-γlevels(P＜0.05).Protein expression of IL-4 and IL-5 in lesional skin tissues was downregulated,while IFN-γ protein expression was upregulated(P＜0.05).Conclusions QXYF ameliorates skin lesions and pruritus in FA-AD mice,potentially by inhibiting Th2-related cytokines and promoting Th1-related cytokine expression.
