ABSTRACT
Objective:To investigate the relationship between serum matrix metalloproteinase-9(MMP-9) level and vascular cognitive impairment with no dementia (VCIND) in patients with cerebral small vessel diseases (CSVD).Methods:A total of 374 patients with CSVD treated in the First Affiliated Hospital of Xinxiang Medical University from January 2016 to January 2020 were collected and 150 healthy subjects in the same period were used as general data of the control group. All subjects were detected for serum MMP-9 level using enzyme linked immunosorbent assay and received cognitive function scoring using Montreal cognitive assessment (MoCA). The 374 patients with CSVD were divided into the Group A(186 cases with vascular cognitive impairment with no dementia) and the Group B(188 cases without cognitive impairment). The general data, serum MMP-9 level and cognitive function score were compared among the three groups and the correlation between MMP-9 level and cognitive function was analyzed.Results:The MMP-9 levels of Groups A and B ( (335.10±105.10)μg/L, (261.62±80.32)μg/L) were higher than those of the control group ( (168.23±48.85)μg/L), and the MMP-9 level of Group A was higher than that of Group B ( P<0.05). The MoCA scores of Groups A and B ( (18.45±5.24), (28.31±1.52) ) were lower than those of the control group (29.49±0.90), and the MoCA scores of Group A were lower than those of Group B ( P<0.05). The serum MMP-9 level, a risk factor for VCIND in patients with CSVD ( β=1.505, OR=1.323, 95% CI=1.149-1.527, P<0.05), was negatively correlated with total score of MoCA scale, visual-spatial and executive function, naming, language, abstract thinking, delayed recall, and directive force factor score ( r=-0.299, r=-0.155, r=-0.383, r=-0.358, r=-0.192, r=-0.259, r=-0.246 respectively, all P<0.05). Conclusion:The increased level of MMP-9 may be a risk factor of VCIND in CSVD patients, and it is closely related to cognitive impairment.
