MIA诱导的OA大鼠模型是一种成熟且广泛使用的模型。关节内注射MIA最初引起严重和急性炎症，这导致OA的更长和退行性阶段17，18。在这项研究中，我们通过MWT和TWL测量了伤害敏感性，并使用成像系统评估了步态改变。先前的报告发现，注射MIA可以提高传入膝关节纤维的敏感性，导致伤害感受，这反映在热痛觉过敏和降低的机械阈值19<sup...

骨关节炎（OA）是世界上最常见的关节疾病，估计影响成人10-12%的人口1。最普遍受累的关节是膝关节，OA在老年人中发病率较高，尤其是女性2。作为一种慢性疾病，OA在几十年内逐渐发展为关节衰竭，症状包括软骨丢失，滑膜炎症，骨癣菌病，功能下降和慢性疼痛3。根据世界卫生组织（WHO）的数据，OA是女性中第四大最普遍的疾病，也是男性中第八大最流行的疾病。到2020年，OA可能成为人类第四大致残性疾病4。然而，目前可用的OA疗法仅解决症状，并延长关节置换手术的时间5。
人类患者的自发性OA往往需要很长时间才能产生关节相关疼痛等临床症状6。在OA的早期阶段，疼痛通常是间歇性的，并且随着疾病的进展变得更加频繁和严重，使其成为患者的主要主诉7。因此，在过去的半个世纪中，已经开发了广泛的OA疼痛动物模型来促进疼痛缓解疗法。OA模型通常分为自发模型和诱导模型。自发模型包括自然发生的模型和转基因模型，它们可以更密切地模拟人类原发性OA的过程8。诱导模型一般可分为两类：1）手术或其他创伤诱导的创伤后OA;或2）关节内注射软骨毒性或促炎物质3。这些模型为OA的病理生理学研究奠定了基础，并为开发减轻疼痛和增加功能的药物做出了巨大贡献。
最近，OA建模最广泛使用的诱导剂是单碘乙酸酯（MIA）。MIA是甘油醛-3-磷酸脱氢酶的抑制剂，可引起软骨基质的变化、降解、软骨流失、滑膜炎等变化，与人类骨关节炎的病理变化相似9.已经注意到，关节内注射MIA在MIA给药后28天引起持续疼痛，表明MIA模型可能有助于研究慢性伤害性疼痛10，11，12。在这项研究中，雄性Sprague-Dawley大鼠接受关节内注射，膝关节中含有0.5、1.5或3mg的MIA。通过注射后1、7、14、21、28和35天的机械和热敏感性评估来测量MIA诱导的关节疼痛的严重程度。在此基础上，选择1.5mg的MIA作为最终浓度，以评估注射后28天的步态模式和组织学变化。

osteoarthritis pain model induced by intra-articular injection of mono-iodoacetate in rats

目前的骨关节炎（OA）动物模型可分为自发模型和诱导模型，两者都旨在模拟人类OA的病理生理变化。但是，疼痛作为OA晚期的主要症状，影响患者的日常生活，可用的模型并不多。单碘乙酸（MIA）诱导模型是应用最广泛的OA疼痛模型，主要用于啮齿动物。MIA是甘油醛-3-磷酸脱氢酶的抑制剂，可导致软骨细胞死亡，软骨变性，骨赘和动物行为的可测量变化。此外，在MIA诱导的模型中可以检测到基质金属蛋白酶（MMP）和促炎细胞因子（IL1 β和TNF α）的表达变化。这些变化与人类OA病理生理状况一致，表明MIA可以诱导可测量和成功的OA疼痛模型。本研究旨在描述大鼠关节内注射MIA的方法，并讨论由此产生的疼痛相关行为和组织病理学变化。

通过这种方法，我们在大鼠中建立了OA疼痛模型并检测了由此产生的变化。MWT和TWL分别反映机械性异常性疼痛和热痛觉过敏。如图 1所示，MIA诱导的机械性异常性疼痛和热痛觉过敏以剂量依赖性方式存在。值得注意的是，MWT的下降从21 d达到峰值至28 d，然后反弹，表明现阶段可能发生关节修复，但3 mg MIA组的MWT仍处于较低水平。TWL的变化与MWT大致一致（图2</stron...
