【摘要】 背景 卒中后抑郁(PSD)是卒中患者常见并发症之一,可增加卒中患者致残率、病死率,但其确
切发病机制仍不明确。目的 通过弥散张量纤维束成像(DTT)观察 PSD 患者脑白质纤维束改变并分析其与抑郁的
相关性。方法 选取 2019 年 9 月至 2020 年 9 月在锦州医科大学附属第一医院住院治疗的首发缺血性脑卒中患者 40
例,根据 PSD 发生情况分为 PSD 组和非 PSD 组,每组 20 例;选取同期在锦州医科大学附属第一医院体检的健康志
愿者 20 例作为正常对照组。三组受试者均行 DTT 检查,比较三组受试者感兴趣区(ROI)各向异性分数(FA)、
神经纤维数量;PSD 组患者各 ROI 病灶侧 FA、神经纤维数量与 24 项版汉密尔顿抑郁量表(HAMD-24)评分的相关
性分析采用 Pearson 相关分析。结果 PSD 组患者下额枕束、皮质脊髓束、额桥束、扣带束、钩束病灶侧 FA 低于非
PSD 组、正常对照组及病灶对侧,下额枕束、皮质脊髓束、额桥束病灶侧神经纤维数量少于非 PSD 组、正常对照组及
病灶对侧(P<0.05)。Pearson 相关分析结果显示,PSD 患者下额枕束、皮质脊髓束、额桥束、扣带束、钩束病灶侧
FA 与 HAMD-24 评分均呈负相关(r 值分别为 -0.469、-0.769、-0.728、-0.801、-0.839,P<0.05);PSD 患者下额枕
束、皮质脊髓束、额桥束病灶侧神经纤维数量与 HAMD-24 评分亦均呈负相关(r 值分别为 -0.858、-0.806、-0.694,
P<0.01)。结论 PSD 患者病灶侧下额枕束、皮质脊髓束、额桥束、扣带束及钩束白质结构存在损伤且与抑郁程度相关,
大脑部分白质纤维束改变可能在 PSD 的发生中具有重要作用。

【Abstract】 Background Post-stroke depression(PSD),a common complication in stroke patients,may increase
the disability and mortality,however, its pathogenesis is unknown yet. Objective To observe the white matter fiber bundle
alterations by diffusion tensor tractography(DTT),and to explore its correlation with depression in patients with PSD. Methods
Participants were selected from the First Affiliated Hospital of Jinzhou Medical University from September 2019 to September
2020, involving 40 inpatients with first-episode ischemic stroke(20 were found with PSD,and 20 without),and 20 physical
examinees as healthy controls. DTT was performed in all participants,fractional anisotropy(FA)and number of fiber bundles
in regions of interest(ROIs)were compared across PSD and non-PSD inpatients and healthy controls. Pearson correlation
analysis was performed to analyze the correlations of FA and number of fiber bundles on the side of stroke in the ROIs with 24-item
Hamilton Rating Scale for Depression(HAMD-24)in PDS inpatients. Results In PSD inpatients,the FA of inferior fronto-
occipital fascicles,corticospinal tract,frontopontine tract,cingulum bundle and uncinate fasciculus on the side of the stroke
was significantly lower than those on the contralateral side(P<0.05). And the number of fiber bundle of inferior fronto-occipital
