急性輕中度腦梗死后認知功能障礙特點及血清SAA、A β與其相關性的研究
[Abstract]:Objective: To analyze the characteristics of cognitive function after acute mild to moderate cerebral infarction in different parts of the brain, and to analyze the relationship between serum amyloid A protein (SAA), amyloid beta protein (P-amyloid, Abeta) and cognitive performance after acute mild to moderate cerebral infarction, and to explore the role of SAA and A P in cognitive function in acute stage of mild to moderate cerebral infarction. Methods: 1. 105 patients with acute mild to moderate cerebral infarction and 30 controls without cerebral infarction were collected from Department of Neurology of Shandong Provincial Hospital. Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment were used. The cognitive function was assessed with the Montreal Cognitive Assessment (MOCA). First, the general data and cognitive scores were compared between the acute cerebral infarction group and the control group without cerebral infarction. Second, according to different sites (including right cerebral hemisphere, left cerebral hemisphere, frontal lobe, parietal lobe, temporal lobe, occipital lobe, brain stem, cerebellum, basal ganglia and thalamus), the scores were Acute infarction was divided into two groups, with and without acute infarction. The influence of risk factors on cognitive function, characteristics of cognitive function and impairment characteristics in different cognitive fields were analyzed statistically. 2. Correlation between SAA, A beta and all influencing factors, including age, sex, and receipt, was analyzed by Spearman correlation coefficient. Education, alpha 2-macroglobulin 2 (a 2-MG), smoking, and other risk factors for cerebrovascular diseases (hypertension, diabetes, dyslipidemia, family history of stroke and stroke history); generalized linear regression analysis was used to explore the cognitive domains of SAA, A beta and MMSE (including time and place orientation, immediate memory, computational power, and short-term memory). Result: 1. 41 (43.8%) patients with acute mild to moderate cerebral infarction had MMSE score < 27; the average score of MMSE and MOCA in acute cerebral infarction group was significantly lower than that in acute cerebral infarction group. In the control group without cerebral infarction (all p0.01), the scores of orientation, short-term memory, language and attention were significantly decreased (all p0.01). Among 105 patients with acute cerebral infarction, 51 (48.6%) had right cerebral infarction, 40 (38.1%) had left cerebral infarction and 31 (29.5%) had basal ganglia infarction. There was significant cognitive impairment in patients with regional infarction (all P 0.05); according to different areas of cognitive impairment, the executive function of patients with left cerebral hemisphere infarction was most impaired (P = 0.027), the language function, naming and attention of patients with frontal infarction were significantly decreased (all P 0.05), memory, language, visual space and persistence of patients with parietal infarction. The patients with temporal lobe infarction had significantly impaired attention (P = 0.043) and language function in basal ganglia infarction (P = 0.05). 2. The total scores of MMSE and MOCA in patients with less than 6 years of education were significantly lower than those in patients with less than 6 years of education. Cognitive impairment was more pronounced in patients with cognitive impairment than in patients with single circulatory system infarction, especially directional impairment. Correlation analysis of Spearman coefficient showed that there was a positive correlation between SAA and alpha 2-MG (0.29, P 0.01). Generalized linear regression analysis between SAA and various cognitive domains in MMSE showed that SAA had a significant effect on time and place orientation (all of which were controlled). The results of generalized linear regression analysis showed that there was no significant correlation between SAA and cognition. The results showed that there was a negative correlation between Abeta and short-term memory after adjusting age, sex, education level and a2-MG, but no correlation between Abeta and cognitive impairment after adjusting the above variables and cerebrovascular factors. Generalized linear regression analysis showed that there was no significant correlation between Abeta and cognitive impairment in MOCA. Mild to moderate cerebral infarction patients generally have cognitive impairment, the incidence of which is as high as 43.8%. Different parts of cognitive impairment have different characteristics, providing theoretical support for different parts of stroke patients to formulate early and accurate cognitive rehabilitation program. 2. The increase of serum SAA may be associated with cognitive impairment after acute mild to moderate cerebral infarction. Guan, especially time, place orientation and computational power (MMSE), but Abeta was not significantly associated with cognitive impairment after acute mild to moderate cerebral infarction.
