摘要:

目的 基于静息态功能磁共振成像低频振幅(ALFF)分析方法探讨膝骨关节炎(KOA)和腰痛两种慢性疼痛患者脑影像学特征的异同。方法 2015年8月至2021年9月在福建福州市各社区招募KOA患者16例及年龄、性别相似的健康人16例(对照组1);从Openpain数据库获得27例腰痛患者和年龄、性别相似的健康人32例(对照组2)。比较受试者的ALFF。采用简明疼痛量表(BPI)对KOA患者进行疼痛评分,采用视觉模拟量表(VAS)对腰痛患者进行疼痛评分,并与ALFF进行相关性分析。结果 与各自对照组相比,KOA和腰痛患者左前脑岛ALFF降低,KOA患者海马和后扣带回ALFF降低,腰痛患者升高;KOA患者左楔前叶、左中扣带回、右中脑导水管周围灰质区域ALFF降低,右中央前回、中央后回ALFF升高;腰痛患者双前扣带回、双眶部额前回、左背外侧前额叶、右内侧前额叶ALFF降低,右海马旁回、右杏仁核ALFF升高;KOA患者左中扣带回ALFF与BPI评分负相关(r = -0.73, P = 0.003),腰痛患者右海马/杏仁核ALFF与VAS评分正相关(r = 0.73, P = 0.003)。结论 不同类型慢性疼痛有共同和特异的脑影像学特征。前脑岛、海马和后扣带回ALFF改变可能是KOA和腰痛的共同病理机制。

Abstract:

Objective To compare the brain imaging characteristics in patients with knee osteoarthritis (KOA) and low back pain (LBP) based on amplitude of low frequency fluctuation (ALFF) of functional magnetic resonance imaging. Methods From August, 2015 to September, 2021, 16 KOA patients and 16 healthy subjects (controls 1) with similar age and gender were recruited from the communities of Fuzhou, Fujian. Other 27 patients with LBP and 32 healthy subjects (controls 2) with similar age and gender were obtained from the Openpain database. The ALFF were analyzed. KOA patients were assessed the pain with Brief Pain Inventory (BPI), and LBP patients were assessed with Visual Analogue Scale (VAS). The correlation between ALFF and pain scores was analyzed. Results Compared with their own controls, the ALFF decreased in the left anterior insula for both KOA and LBP patients. The ALFF decreased in the hippocampus and posterior cingulate cortex in KOA patients, while increased in LBP patients. ALFF in the left precuneus, left middle cingulate cortex and right periaqueductal gray matter decreased in KOA patients, and ALFF increased in the right precentral/postcentral gyrus. ALFF of bilateral anterior cingulate cortex, bilateral orbital anterior frontal cortex, left dorsolateral prefrontal cortex and right medial prefrontal cortex decreased in LBP patients, and ALFF increased in the right parahippocampal gyrus and right amygdala. ALFF of the left middle cingulate cortex negatively correlated with BPI score in KOA patients (r = -0.73, P = 0.003), and ALFF of the right hippocampus/amygdala positively correlated with VAS score in LBP patients (r = 0.73, P = 0.003). Conclusion There are common and specific brain imaging features in different types of chronic pain. The alteration in the left anterior insula, hippocampus and posterior cingulate gyrus may be the common mechanism for KOA and LBP.
