    摘要:

    目的 本研究旨在运用药物干预及休息后再激发的方法构建气虚血瘀证慢性荨麻疹(CU)复发动物模型,并对模型进行评价。 方法 将 30 只 BALB/ c 小鼠随机分为 2 组:空白组 12 只,模型组 18 只。 空白组采用普通饮食,于正常环境下饲养;模型组采用被动皮肤致敏、利血平股四头肌注射、休息后小剂量激发的方法构建气虚血瘀证 CU 复发动物模型。 通过小鼠的一般情况、体质量、瘙痒程度、气虚血瘀评分、舌象、旷场实验、机械疼痛、机械痛阈值、血清水平及病理学检测,对该模型进行评价。 结果 造模后,模型组小鼠瘙抓显著(P < 0. 01),第 6、7 次免疫后苏木素-伊红(HE)、甲苯胺蓝染色检测呈现典型 CU 病理表现,且模型组小鼠精神萎靡不振,对外界刺激反应迟钝,不喜动、嗜睡,体虚无力明显,体型较小而肉脱,毛发枯槁,耳廓、肛周、爪甲暗红,较空白组体质量降低(P < 0. 01),旷场实验平均速度和总路程下降(P < 0. 01),实验室指标肾上腺皮质激素、烟碱型胆碱受体 α1、二磷酸腺苷显著上升(P < 0. 01),三磷酸腺苷降低(P < 0. 05),机械痛阈值显著降低(P < 0. 01),舌象 R 值、G 值与 B 值均显著降低(P < 0. 01),呈“紫舌” “暗红舌”。 结论 被动皮肤致敏、利血平股四头肌注射、休息后小剂量激发的方法能够构建气虚血瘀证 CU 复发动物模型,可以将小鼠的瘙痒程度、“气虚血瘀”评估量表评分、舌象、旷场实验、机械疼痛、机械痛阈值、血清水平及病理学检测的变化作为模型评价的关键指标。

    Abstract:

    Objective This study aimed to construct and evaluate an animal model of recurrent chronic urticaria(CU) with qi deficiency and blood stasis syndrome using drug intervention and re-challenge after rest. Methods Thirty BALB/ c mice were randomly divided into two groups: a control group (n=12) and a model group (n=18). The control group was fed a standard diet and housed under normal conditions. The model group was subjected to passive cutaneous sensitization, reserpine injection into the quadriceps femoris, and low-dose re-challenge after rest to establish the recurrent CU model with qi deficiency and blood stasis syndrome. The model was evaluated based on general condition, body mass, scratching behavior, qi deficiency and blood stasis scores, tongue appearance, open-field test result, mechanical pain sensitivity, mechanical pain threshold, serum biomarkers, and histopathological examination. Results After modeling, the model group exhibited significantly increased scratching behavior (P < 0. 01). Following the 6th and 7th immunizations, hematoxylin-eosin (HE) and toluidine blue staining revealed typical pathological features of CU. The model mice displayed lethargy, reduced responsiveness to external stimuli, decreased activity, drowsiness, physical weakness, emaciation, dull fur, and dark-red ears, perianal regions, and claws. Compared with the control group, the model group showed reduced body mass ( P < 0. 01),decreased average speed and total distance in the open-field test (P < 0. 01), elevated serum levels of adrenocortical hormones, nicotinic acetylcholine receptor α1, and adenosine diphosphate ( P < 0. 01 ), reduced adenosine triphosphate (P < 0. 05), and a significantly lower mechanical pain threshold (P < 0. 01). Tongue image analysis indicated significantly decreased R, G, and B values (P < 0. 01), presenting as a “purplish tongue” or “dark-red tongue”. Conclusions The method combining passive cutaneous sensitization, reserpine injection into the quadriceps femoris, and low-dose re-challenge after rest can established an animal model of recurrent CU with qi deficiency and blood stasis syndrome. Key evaluation indicators included scratching behavior, qi deficiency and blood stasis scores, tongue appearance, open-field test performance, mechanical pain se
