Relationship between sutured nucleus echo and serum metal and non-motor symptoms in patients with Parkinson′s disease / 中华神经科杂志

ABSTRACT

Objective:To explore the relationship between the changes of midbrain raphe nucleus echo and blood trace metals, non-motor symptoms in patients with Parkinson′s disease (PD).Methods:A total of 177 patients with PD were recruited from Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology from November 2017 to December 2019. Their non-motor symptoms were assessed by a series of PD-related scales. All subjects completed transcranial color-coded sonography, and were divided into two groups according to the continuity of raphe nucleus echo. The difference of trace metals in peripheral blood and the scores of non-motor symptoms were analyzed.Results:The serum iron level of PD patients in the continuous echo of raphe nucleus group (117 cases; 15.33 （11.30, 18.93） μmol/L) was higher than that of the discontinuous group (60 cases; 12.52 （4.15, 16.00） μmol/L, t=-2.294, P=0.022), so was the scores of Scale for outcomes in PD for Autonomic Symptoms (34.00 （28.00, 39.00） vs31.00 （26.25, 36.00）， t=-2.044, P=0.041). There was no significant difference in the level of serum copper, hemoglobin, ceruloplasmin, and the scores of Movement Disorder Society Unified Parkinson′s Disease Rating Scale, Parkinson′s Disease Sleeping Scale, 39 items Parkinson′s Disease Questionnaire, Hamilton Depression Rating Scale and Hamilton Anxiety Rating Scale between the two groups. Conclusion:There was significant difference in serum iron levels and the scores of SCOPA-AUT between the two groups, but no difference in depression, sleep, and daily living ability.
