基于肠“神经—免疫”网络的白术茯苓汤不同配比干预脾气虚型克罗恩病机制研究的探讨

Exploration and Discussion on Mechanisms of Different Proportional Compatibility of Bai-Zhu Fu-Ling Decoction Interfering Spleen-Qi Deficiency Crohn's Disease by Intestinal Nerve-immune Network

克罗恩病(CD)的发生与环境、遗传、感染和免疫等多种因素相关,因缺乏特异性治疗措施,是现代难治性疾病之一。中医通过辨证论治,可以有效缓解病情、改善生存质量、减轻西药的副作用。白术、茯苓配伍正好契合CD脾虚夹湿的常见病机,是治疗CD的核心配伍结构。前期研究显示白术茯苓汤可降低脾虚模型VIP、下调VIP受体、升高s Ig A。为进一步明确神经递质及其与免疫系统的相互关联在CD发病中的作用及该方不同配比的干预机制,本课题观察了该方不同配比对脾气虚型CD的"神经—免疫"网络相关递质及其受体功能、细胞因子分泌及"TLR4-NF-κB"信号转导的影响,为深入探讨中药复方治疗CD提供相关参考与基础。

The onset of Crohn’s disease （CD） is the interaction of environment, heredity, infection, immune and other factors. It is also closely related to abnormal immune functions. Without special treatment, CD is identified as a modern refractory disease. By syndrome differentiation and treatment, traditional Chinese medicine （TCM） can effectively relieve disease conditions, improve the quality of life and reduce side effects of modern medication. The core compatibility ofBai-Zhu andFu-Ling can reinforce spleen-qi and dispel dampness, which met the common pathogenesis of CD. Therefore, the combination is comprehensively used in the compound prescription. Our previous study found thatBai-Zhu Fu-Ling decoctioncan reduce the vasoactive intestinal peptide （VIP） of animal model of spleen-qi deficiency, downregulate VIP receptors, decrease the affinity of VIP receptors and improve animal model’s sIgA. To further clarify the effects about neurotransmitters and their correlation with the immune system in the pathogenesis of CD and the intervention mechanism treated by different proportional compatibility of Bai-Zhu Fu-Ling decoction, we studied influences of the decoction on related transmitters of nerve- immune network and functions of receptors, as well as cytokine secretion and signal transduction of TLR4-NF-κB. Our studies can provide references and foundations to further explore TCM treatment of CD.
