摘要: 背景 Wilson病(WD)炎症水平增高且与认知损害密切相关。研究表明,晚期糖基化终产物受体(RAGE)/核因子κB(NF-κB)信号通路的激活是介导认知障碍的重要炎症机制,但其在WD伴轻度认知障碍(MCI)患者血清的表达水平尚不清楚。目的 探讨Wilson病患者血清RAGE/NF-κB通路表达水平变化及其对轻度认知损害的影响。方法 收集2024年1月至2025年1月在安徽中医药大学第一附属医院脑病中心住院的23例WD伴MCI患者为WD-MCI组。选取同期年龄、性别、受教育程度相匹配的认知功能正常的健康体检者23例为对照组。采用简易精神状态检查量表(MMSE)、霍普金斯语言学习测试(HVLT)、波士顿命名测试第二版(BNT-2)、画钟测试(CDT)、连线测试-A(TMT-A)、工具性日常生活能力量表(IADL)分别对患者的整体认知状态和记忆、语言、视空间、执行、日常生活能力进行评价。应用酶联免疫吸附法和qRT-PCR测定血清RAGE/NF-κB信号通路关键分子表达水平。比较两组认知功能、血清RAGE水平及NF-κBp65 mRNA表达水平的差异。采用Pearson检验分析血清RAGE水平、NF-κBp65 mRNA表达水平与认知功能评分的相关性。结果 与对照组相比,WD-MCI组MMSE、HVLT、BNT-2、CDT评分均明显降低,TMT-A、 IADL评分均显著升高(P<0.05)。WD-MCI组血清RAGE水平、NF-κBp65 mRNA表达水平均高于对照组(P<0.05)。Pearson相关分析显示,血清NF-κBp65 mRNA表达水平血清RAGE水平及NF-κBp65 mRNA表达水平与MMSE(r=-0.866,-0.729)、HVLT(r=-0.721,-0.728)、BNT-2(r=-0.381,-0.382)、CDT(r=-0.788,-0.709)评分呈负相关,与TMT-A(r=0.774,0.524)、IADL(r=0.433,0.376)评分呈正相关(P<0.05)。结论 Wilson病患者血清RAGE/NF-κB通路表达水平明显增高,且与认知功能损害呈显著正相关。

Abstract: Background Wilson's disease (WD) is associated with elevated inflammatory levels and closely linked to cognitive impairment. Studies suggest that activation of the receptor for advanced glycation end products (RAGE)/nuclear factor kappa B (NF-κB) signaling pathway is a critical inflammatory mechanism mediating cognitive dysfunction, yet its expression in serum of WD patients with mild cognitive impairment (MCI) remains unclear. Objective To investigate changes in serum RAGE/NF-κB pathway expression and their impact on MCI in WD patients. Methods A total of 23 WD patients with MCI (WD-MCI group) hospitalized at the Encephalopathy Center of the First Affiliated Hospital of Anhui University of Chinese Medicine from January 2024 to January 2025 were enrolled. Age-, sex-, and education-matched healthy controls (n=23) were recruited. Cognitive function was assessed using the Mini-Mental State Examination (MMSE), Hopkins Verbal Learning Test (HVLT), Boston Naming Test-Second Edition (BNT-2), Clock Drawing Test (CDT), Trail Making Test-A (TMT-A), and Instrumental Activities of Daily Living Scale (IADL). Serum RAGE levels and NF-κB p65 mRNA expression were measured using enzyme-linked immunosorbent assay (ELISA) and qRT-PCR, respectively. Differences in cognitive scores, serum RAGE levels, and NF-κB p65 mRNA expression between groups were compared. Pearson correlation analysis evaluated associations between RAGE/NF-κB p65 mRNA levels and cognitive scores. Results Compared with controls, the WD-MCI group showed significantly lower MMSE, HVLT, BNT-2, and CDT scores, and higher TMT-A and IADL scores (P<0.05). Serum RAGE levels and NF-κB p65 mRNA expression were elevated in the WD-MCI group (P<0.05). Pearson analysis revealed that serum RAGE levels and NF-κB p65 mRNA expression negatively correlated with MMSE (r=-0.866,-0.729), HVLT (r=-0.721,-0.728), BNT-2 (r=-0.381,-0.382), and CDT(r=-0.788,-0.709)scores, and positively correlated with TMT-A (r=0.774,0.524)and IADL (r=0.433,0.376) scores (P<0.05). Conclusion WD patients exhibit increased serum RAGE/NF-κB pathway activity, which is significantly associated with mild cognitive impairment.
