ABSTRACT
This practice guideline focuses on the cognitive assessment for mild cognitive impairment in the Guangdong-Hong Kong-Macao Greater Bay Area. To achieve the standardization and normalization of its clinical practice and generate individualized intervention, the National Core Cognitive Center of the Second Affiliated Hospital of Guangzhou Medical University, the Cognitive Disorders Branch of Chinese Geriatic Society, the Dementia Group of Neurology Branch of Guangdong Medical Association and specialists from Hong Kong and Macao developed guidelines based on China's actual conditions and efficiency, economic cost and accuracy. The article addresses the significance, background, and the process of the assessment and follow-up to realize the promotion and dissemination of cognitive assessment.
ABSTRACT
Objective To investigate the correlation between large artery atherosclerotic stroke and paraoxonase 1 (PON1) Q192R polymorphism.Methods Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to detect the PON1 Q192R polymorphism of 120 patients with large artery atherosclerotic stroke (case group) and 117 healthy subjects (control group).Results There was significant difference in the genotype distribution of PON1 Q192R (x2 =18.727,P＜0.001) and the allele frequency distribution (x2 =16.427,P ＜0.001) between the case group and the control group.Multivariate logistic regression analysis showed that RR genotype was an independent risk factor for large artery atherosclerotic stroke (odds ratio 1.377,95％ confidence interval 1.032-2.185; P =0.026).Conclusions The allelic gene mutation rate of PON1 Q192R in patients with large artery atherosclerotic stroke was significantly higher than that in the healthy population.RR genotype is an independent risk factor for large artery atherosclerotic stroke.
