摘  要:目的探讨帕金森病(Parkinson’s disease,PD)患者不同认知状态下脉络丛(choroid plexus,CP)体积变化及其与其他脑区结构体积的相关性。方法本研究为横断面研究,纳入2023年5月至2024年4月期间就诊于陆军军医大学第一附属医院神经外科的48例PD患者及从健康体检中心招募的35例健康对照(healthy controls,HC),基于简易精神状态检查量表(Mini-Mental State Examination,MMSE)评估结果,将PD患者分为帕金森病伴认知功能障碍组(Parkinson’s disease with cognitive impairment,PD-CI)27例和帕金森病认知功能正常组(Parkinson’s disease with normal cognitive function,PD-NC)21例。采用3.0T磁共振成像(magnetic resonance imaging,MRI)进行MPRAGE序列扫描,并使用FreeSurfer 6.0软件获得脉络丛体积(choroid plexus volume,CPV)与其他脑区结构的体积。对CPV进行校正,计算其与估算的总颅内体积(estimated total intracranial volume,eTIV)的比值。调整混杂因素后,通过偏相关分析评估CPV/eTIV比值与其他脑区结构体积及认知量表评分之间的关系。使用多元线性回归分析进一步探究PD-CI组中CPV与认知功能之间的关系。结果与HC组相比,PD-CI组的CPV显著增大(P=0.029)。PD-CI组中,CPV/eTIV比值与侧脑室体积(r=0.689,P=0.001)、第三脑室体积(r=0.592,P=0.006)、脑脊液(cerebrospinal fluid,CSF)体积(r=0.508,P=0.022)、脑白质高信号(white matter hyperintensities,WMH)体积(r=0.486,P=0.030)呈显著正相关,同时与尾状核体积(r=-0.530,P=0.016)、丘脑体积(r=-0.477,P=0.033)及MMSE评分呈显著负相关(r=-0.483,P=0.031)。而PD-NC组中,CPV/eTIV比值仅与CSF体积(r=0.571,P=0.021)呈显著正相关;在PD-CI组中,CPV/eTIV比值与MMSE评分行多元线性回归分析,结果显示两者仍呈显著负相关(β=-0.388,P=0.046)。结论PD患者的认知功能障碍可能与CPV变化密切相关,提示CPV可作为评估PD认知损伤的潜在影像学标志物。Objective To investigate the change in choroid plexus(CP)volume in Parkinson’s disease(PD)patients with different cognitive states and its correlation with structural volumes of other brain regions.Methods A cross-sectional study was conducted on 48 PD patients admitted in Department of Neurosurgery of the First Affiliated Hospital of Army Medical University between May 2023 and April 2024,and on 35 healthy controls(HC)recruited through a physical exam center.According to the results of Mini-Mental State Examination(MMSE),the patients were divided into PD with cognitive impairment(PD-CI)group(n=27)and PD with normal cognitive function(PD-NC)group(n=21).3.0T magnetic resonance imaging(MRI)was performed using MPRAGE sequences,and CP volume and volumes of other brain regions were obtained using FreeSurfer 6.0 software.The CP volume was adjusted by calculating the ratio of its volume to estimated total intracranial volume(eTIV).After controlling for confounders,partial correlation analysis was used to assess the relationship between the CPV/eTIV ratio and the volumes of other brain regions as well as cognitive scale scores.Additionally,multiple linear regression analysis was performed to further explore the relationship between CPV and cognitive function in the PD-CI group.Results Compared to the HC group,the CPV in the PD-CI group was significantly larger(P=0.029).In the PD-CI group,the CPV/eTIV ratio showed significant positive correlations with the volume of the lateral ventricles(r=0.689,P=0.001),the volume of the third ventricle(r=0.592,P=0.006),the volume of cerebrospinal fluid(CSF)(r=0.508,P=0.022),and white matter hyperintensities(WMH)(r=0.486,P=0.030),but was negatively correlated with the volume of the caudate nucleus(r=-0.530,P=0.016),the volume of the thalamus(r=-0.477,P=0.033),and the MMSE scores(r=-0.483,P=0.031).But in the PD-NC group,the CPV/eTIV ratio was only positively correlated with CSF volume(r=0.571,P=0.021).Multiple linear regression analysis indicated that the CPV/eTIV ratio and MMSE scores
