摘 要:目的探讨帕金森病(Parkinson's disease,PD)患者在不同亚组中形态学改变模式的性别差异。材料与方法从帕金森病进展标记计划数据库共获取278名参与者的高分辨率T1加权磁共振成像和临床量表数据。以快速眼动睡眠行为障碍(rapid eye movement sleep behavior disorder,RBD)筛查问卷的5分为截止点,分为PD-pRBD(≥5分)和PDnonRBD(<5分),最后被试包括93名PD-pRBD患者和114名PDnonRBD患者以及71名健康对照(healthycontrol,HC)。计算解剖学工具箱12(Computational Anatomy Toolbox 12,CAT12)用于获取灰质体积和皮层形态学指标数据,随后基于皮层形态学指标构建个体水平的形态学相似性网络。最后用图论分析的方法计算网络拓扑属性。结果PD-pRBD组中,男性额叶和颞叶的灰质体积(gray matter volume,GMV)低于女性(P=0.008、0.002),而女性额叶的回旋指数(gyrification index,GI)低于男性(P=0.024)。PDnonRBD组中,男性额叶的GI比女性低(P=0.009)。基于图论的网络分析显示,男性PD-pRBD患者较女性患者表现更低的网络信息整合能力,特别是在分形维度(fractal dimension,FD)网络的全局属性方面。此外,PD-pRBD组男性患者在霍普金斯语言学习测试-修订版(Hopkins Verbal Learning Test-Revised,HVLT-R)的延迟记忆评分和蒙特利尔认知评估(Montreal Cognitive Assessment,MoCA)与形态学网络指标密切相关(均P<0.05)。结论伴随和不伴随RBD的PD患者在单纯形态学和网络层面都具有显著性别特异性模式,同时PD-pRBD组中男女之间的性别差异较nonRBD组更加广泛,并且进一步与认知相关,这一发现强调了在PD-pRBD患者诊治中考虑性别差异的重要性。Objective:To explore gender differences in morphological change patterns among different subgroups of Parkinson's disease(PD) patients.Materials and Methods:High-resolution T1-weighted magnetic resonance imaging and clinical scale data were collected from a total of 278 participants in the Parkinson's disease Progression Marker Initiative database.Using a cutoff score of 5 on the rapid eye movement sleep behavior disorder(RBD) screening questionnaire,patients were classified into PD-pRBD(≥ 5 points) and PD-nonRBD(< 5 points) groups.The final sample included 93 PD-pRBD patients,114 PDnonRBD patients,and 71 healthy controls(HC).The Computational Anatomy Toolbox 12(CAT12) tool was utilized to gather data on gray matter volume(GMV) and cortical morphological metrics.Subsequently,individual-level morphological similarity networks were constructed based on these cortical metrics.Finally,the topological properties of the network were analyzed using graph theoretic methods.Results:In the PD-pRBD group,GMV in the frontal and temporal lobes of males was lower than that of females,while the gyrification index(GI) in the frontal lobes was lower in females than in males(P = 0.024).However,the GI of the frontal lobe in males was lower than that in females within the PDnonRBD group(P = 0.009).Network analyses based on graph theory revealed that male PD-pRBD patients displayed lower network information integration compared to female patients,particularly in terms of the global properties of fractal dimension(FD) networks.Moreover,in the PD-pRBD group,male patients showed a strong correlation between morphological network metrics and cognitive performance as measured by the delayed memory score of Hopkins Verbal Learning Test-Revised(HVLT-R) memory scores and the Montreal Cognitive Assessment(MoCA)(all P < 0.05).Conclusions:PD patients with and without RBD exhibit significant sex-specific patterns at both the morphological and network levels.Moreover,the sex differences between males and females in the PD-RBD group are more ext
