【摘要】 目的：分别以免疫低下和免疫紊乱为研究对象,探讨艾灸免疫调节作用的局部作用机制。方法：(1)采用D-半乳糖注射形成的亚急性衰老模型为艾灸免疫低下调节载体,给予背部膀胱经肺俞-肾俞施灸,检测血清皮质酮含量及施灸部位皮肤MHC-Ⅱ、IL-12、CD-80、波形蛋白的表达；(2)采用完全弗氏佐剂注射造模佐剂性关节炎为免疫紊乱研究载体,给予艾灸“足三里”,以足跖肿胀改善、血清TNF-α、IL-1β、IL-10变化为艾灸免疫紊乱调节指标,并同时检测艾灸局部、脾脏、胸腺、下丘脑瘦素及瘦素受体表达和血清瘦素含量变化。结果：(1)D-半乳糖造模形成的衰老模型大鼠血清皮质酮含量高于对照组,差异具有统计学意义,p<0.01；艾灸组血清皮质酮含量低于模型组,p<0.01。模型组皮肤MHC-Ⅱ、IL-12、CD80、波形蛋白表达阳性细胞数少于空白组,表达强度也低于空白组,p<0.01；艾灸组施灸部位皮肤MHC-Ⅱ、IL-12、CD80、波形蛋白表达阳性细胞数多于模型组,表达强度也高于空白组,p<0.01。(2)艾灸组足跖肿胀程度从开始接受治疗后一直呈逐步下降趋势,在第7天与模型组相比,有显著差异(p<0.05),到第14天时,差异更为显著(p<0.01)。模型组TNF-α、IL-1β含量显著高于对照组,p<0.01；艾灸组的TNF-α、IL-1β含量显著低于对照组,p<0.01。模型组IL-10含量显著高于对照组,p<0.01；艾灸组的工L-10含量也显著高于对照组,p<0.01。模型组穴位局部瘦素、瘦素受体表达阳性细胞数少于空白组,表达强度也低于空白组,p<0.01;艾灸组穴位局部皮肤瘦素、瘦素受体表达阳性细胞数多于模型组,表达强度也高于空白组,p<0.01。模型组血清瘦素含量显著低于对照组,p<0.01；艾灸组血清瘦素含量显著高于对照组,p<0.05。模型组大鼠脾脏、胸腺瘦素、瘦素受体表达阳性细胞数、表达强度与空白组比较,差异没有统计学意义,P>0.05；艾灸组脾脏、胸腺瘦素、瘦素受体表达阳性细胞数、表达强度与模型组比较,差异也没有统计学意义,p>0.05。模型组大鼠下丘脑瘦素、瘦素受体表达阳性细胞数多于对照组,p<0.01,表达强度也高于空白组,p<0.01；艾灸组下丘脑瘦素、瘦素受体表达阳性细胞数多于模型组,P<0.01,表达强度也高于模型组,p<0.05。结论：(1)艾灸可纠正衰老低下的免疫状态,可能与艾灸施术部位的MHC-Ⅱ、IL-12、CD80及波形蛋白的皮肤免疫激活有关；(2)艾灸可调整佐剂性关节炎模型紊乱的免疫功能,可能与下丘脑和穴位局部的瘦素、瘦素受体的表达增强有关；(3)艾灸对免疫调节的局部作用机制可能与神经免疫网络一起,形成艾灸调节免疫的皮肤-神经免疫网络调节新的机制。更多还原

【Abstract】 Objective:To explore local action of immunological regulation by moxibusion in hypoimmunity and immunologic derangement animal model.Methods:(1)In the first part of our study,we used subac senescent rat model made by D-galactose injection as hypoimmunity subjects. After moxibustion on points from BL13 to BL23 of the Foot bladder meridian, we measured the content of serumal cortisol(CS) and the expresstion of major histocompatibility complex II(MHC-Ⅱ), Interleukin 12(IL-12), CD80, vimentin in local skin; (2) In the second part,we used adjunctive arthritis(AA) model made by Ferund’s complete adjuvant(FCA) injection as immunologic derangemen subjects. After moxibusion on point ST36, we measured the changes of voix pedis’ swelling and tumor necrosis factor alpha(TNF-α), IL-1β, IL-10 in serum to evaluate immunologic derangemen immunologic derangemen. Meanwhile, we also examine the expression of leptin and leptin acceptor in the partial skin of moxibustion, spleen, thoracic gland, hypothalamus and the content of leptin in serum to uncover the mechanism.Results:(1)The content of CS in model group is higher than that in control group with significant statistical differences(p< 0.01);While the content of CS in moxa group is lower than that in model group(p< 0.01). For the expression of MHC-II, IL-12, CD-80, vimentin in local skin, in model group, the numbers of positive cells are less and the expressional intensity is lower than those in control group(p< 0.01), but the numbers of positive cells in moxa group are more than those in model group(p< 0.01). (2) Compared with model group, voix pedis’ swelling in moxa group got gradually better and better.At day 7, there was statistical difference between them (p<0.05) but significant difference come out at day 14 (p<0.01). As the content of TNF-αand IL-1β, they are more in model group than those in control group(p< 0.01). However, the content of IL-10 in model group is more markedly than that in control group, so do the moxa group(p< 0.01). For changes of leptin and leptin receptor in ST36, the numbers of positive cells and the expression in model group are less than those in control group (p< 0.01), while the numbers of positive cells in moxa group are more than that in control group. In addition, the intensity of expression of leptin and leptin receptor in ST36 in moxa group is higher than that of control group(p< 0.01). The lepten content of serum in model group is higher markedly than that in control group(p< 0.01); the leptin content in serum in moxa group is higher than that in control group(p< 0.05). For the numbers of positive cells and the expression of lepten and leptin receptor, there are no statistical significance in spleen and thoracic gland between model and control group(P>0.05); so do the moxa group. However, for leptin and leptin receptor in hypothalamus, the numbers of positive cells in model group have statistical significance compared to control group(p<0.01), the expression in model group is higher than that in control group(p<0.01), the numbers of positive cells in moxa group are more than that in model group of lepten and leptin receptor in hypothalamus, p<0.01, the expression in moxa group is stronger than that inmodel group of lepten and leptin receptor in hypothalamus, p<0.05.Conclusions:(1)Moxibustion may be activiate the expression of MHC-Ⅱ, IL-12, CD-80, vimentin in local skin to rectify hypoimmunity. (2) Moxibus-tion could enhance the expression of lepten and leptin receptor to adjust immunologic derangemen in AA model. (3) NICS,which is composed of local immune and neural immune system, would be a novel regulation tagert for moxibustion.更多还原
