摘要:

文题释义:

薄荷油:薄荷为一种辛凉解表药物,其性寒凉,芳香走窜,力能透筋骨,多服久服,令人虚冷。具有兴奋中枢神经以及抗炎镇痛、抗病毒等作用,而薄荷油是薄荷发挥功效和产生毒性的主要物质基础。有研究表明大剂量薄荷油在一定程度上能够诱导类阳虚状态。

阳虚寒凝型:阳气有温暖肢体及脏腑的作用。阳气不足,失去温煦推动,代谢活动下降,其表现为畏寒肢冷、面色苍白、大便溏薄、小便清长、脉沉微无力等。寒为阴邪,性凝滞而收缩,易伤阳气,寒凝则表现为痉挛疼痛、腰膝冷痛喜温。

背景:课题组前期用石膏铁丝固定法建立了兔膝骨性关节炎模型,但尚未建立膝骨性关节炎的中医证型的模型。

目的:实验拟通过薄荷油叠加气候箱探索建立兔阳虚寒凝型膝痹模型的可行性,为以后的研究奠定基础。

方法:将32只实验动物随机分为正常组、模型组、阳虚组、阳虚寒凝组,除正常组外均予石膏制动法固定兔膝关节8周;阳虚组在固定第7周开始每日上午予薄荷油灌胃2周;阳虚寒凝组每日置于4 ℃的气候箱1.5 h,在制动 6周后叠加阳虚组操作。灌胃7,14 d后用ELISA检测血清中促甲状腺素T4变化;待膝痹造模达到8周后,取关节软骨、半月板、滑膜行组织学评分;同时观察动物行为学,采用红外线热成像仪检测体表温度变化。实验方案经新疆医科大学第一附属医院动物实验伦理委员会批准(批准号为IACUC-20170222026)。

结果与结论:①行为学中可观察到阳虚寒凝组出现相关阳虚寒凝证的症状;②阳虚寒凝组兔足部温度低于正常组和模型组(P < 0.05);③阳虚组和阳虚寒凝组血清T4值均低于正常组(P < 0.05);④膝关节Mankin评分:阳虚组、阳虚寒凝组均较正常组高(P < 0.05)较模型组低(P < 0.05);⑤半月板、滑膜苏木精-伊红显示,阳虚组、阳虚寒凝组与模型组比较,组间差异不明显;⑥从组织形态上,结合T4、红外线热成像仪、行为学观察结果,可以说明薄荷油叠加气候箱在一定程度上模拟了疾病状态,可以为阳虚寒凝型骨关节炎模型建立提供一定的参考。

Abstract:

BACKGROUND: Our preliminary studies have established a rabbit model of knee osteoarthritis using gypsum wire fixation, but the model of traditional Chinese medicine (TCM) syndrome of knee osteoarthritis has not been prepared.

OBJECTIVE: To assess the feasibility of establishing a rabbit model of yang deficiency and cold coagulation using peppermint oil and climate chamber, to lay the foundation for future research.

METHODS: Thirty-two experimental animals were randomly divided into normal group, model group, yang deficiency group and yang deficiency-cold coagulation group. Except for the normal group, the rabbit knee joints were fixed with plaster fixator brake method for 8 weeks. The yang deficiency group was given daily perfusion of peppermint oil for 2 weeks at the beginning of the 7th week of fixation. In the yang deficiency-cold coagulation group, the rabbits were placed in a climate chamber at 4 °C for 1.5 hours every day, and given daily perfusion of peppermint oil after 6 weeks of braking. After 7 and 14 days of intragastric administration, the serum level of thyrotropin (T4) was detected by ELISA. After 8 weeks of modeling, the articular cartilage, meniscus and synovium were taken for histological scoring. Animal behaviors were observed, and body surface temperature was detected using an infrared thermal imager. The experimental protocol was approved by the Animal Ethics Committee of the First Affiliated Hospital of Xinjiang Medical University (approval No. IACUC-20170222026).

RESULTS AND CONCLUSION: For behavior observation, the symptoms of yang deficiency-cold coagulation appeared in the yang deficiency-cold coagulation group. The plantar temperature of the yang deficiency-cold coagulation was lower than that of the normal and model groups (P < 0.05). The serum T4 level was lower in the yang deficiency group and yang deficiency-cold coagulation group than the normal group (P < 0.05). The Mankin scores of the knee joints in two yang deficiency groups were both higher than that in the normal group (P < 0.05) but lower than that in the model group (P < 0.05). Hematoxylin-eosin staining of the meniscus and synovial membrane indicated the yang deficiency group and the yang deficiency-cold coagulation group had no significant difference from the model group. Histomorphological findings elucidated that the peppermint oil with climate box contributes to simulating the disease state to a certain extent, which can provide a reference for establishing the rabbit knee osteoarthritis model of yang deficiency-cold coagulation type.
