| 目的 观察伴单侧肢体运动症状的早期帕金森病（PD）患者双侧大脑半球胶质淋巴系统功能改变。方法 前瞻性纳入52例仅单侧肢体出现运动症状的早期PD患者，包括左发型（LPD）21例（LPD组）、右发型（RPD）31例（RPD组）；另招募28名健康人作为健康对照组（HC组）。比较3组及两两组间临床表现及沿血管周围间隙的弥散张量成像分析（DTI-ALPS）指数，分析后者与临床量表评分结果的相关性。结果 3组间汉密尔顿抑郁量表（HAMD）评分差异有统计学意义（P<0.05）；LPD组和RPD组HAMD评分均高于HC组（P均<0.017）。3组间左侧大脑半球DTI-ALPS （DTI-ALPS_L）和右侧大脑半球DTI-ALPS （DTI-ALPS_R）指数差异均有统计学意义（P均<0.05）；LPD组DTI_ALPS_R指数、RPD组DTI_ALPS_L指数均低于HC组（P<0.017）。PD患者双侧大脑半球DTI-ALPS指数与临床量表评分无明显相关性（P均>0.05）。结论 PD患者胶质淋巴系统功能减退与运动症状同样呈偏侧化，表现为LPD患者DTI-ALPS_R指数下降、RPD患者DTI-ALPS_L指数下降。 |

| Objective To observe the glymphatic system functional changes of bilateral cerebral hemispheres in early-stage Parkinson disease (PD) patients complicated with unilateral limb motor symptoms. Methods A total of 52 early-stage PD patients complicated with unilateral limb motor symptoms were prospectively enrolled, including 21 cases of left-onset PD (LPD group), 31 cases of right-onset PD (RPD group). Meanwhile, 28 healthy individuals were recruited as healthy controls (HC group). Clinical data and indices of diffusion tensor imaging analysis along the perivascular space (DTI-ALPS) were compared among 3 groups and between each 2 groups. The correlations of DTI-ALPS indices and clinical scales were analyzed. Results Significant difference of Hamilton depression scale (HAMD) score was found among 3 groups (P<0.05). HAMD score of LPD group and RPD group were higher than that of HC group (both P<0.017). There were significant differences of left and right cerebral hemispheres DTI-ALPS (DTI-ALPS_L, DTI-ALPS_R) indices among 3 groups (both P<0.05). DTI_ALPS_R in LPD group was lower than that in HC group (P<0.017), and DTI_ALPS_L in RPD group was lower than that in HC group (P<0.017). No obvious correlation of bilateral cerebral hemisphere DTI-ALPS indices with clinical scales was detected in PD patients (all P>0.05). Conclusion Like that of motor symptoms, glymphatic system dysfunction of PD patients had characteristics of laterality, manifested as DTI_ALPS_R decreased in LPD patients while DTI_ALPS_L decreased in RPD patients. |
