ABSTRACT
In this study, the distribution of five Alzheimer's disease (AD)-related single nucleotide polymorphisms (SNPs) in the Han population was examined in combination with the evaluation of clinical cognition and brain pathological analysis. The associations among SNPs, clinical daily cognitive states, and postmortem neuropathological changes were analyzed in 110 human brains from the Chinese Academy of Medical Sciences/Peking Union Medical College (CAMS/PUMC) Human Brain Bank. APOE ε4 (OR = 4.482, P = 0.004), the RS2305421 GG genotype (adjusted OR = 4.397, P = 0.015), and the RS10498633 GT genotype (adjusted OR = 2.375, P = 0.028) were associated with a higher score on the ABC (Aβ plaque score, Braak NFT stage, and CERAD neuritic plaque score) dementia scale. These results advance our understanding of the pathogenesis of AD, the relationship between pathological diagnosis and clinical diagnosis, and the SNPs in the Han population for future research.

Objective To get well-informed of the practical skills examination of residents' standardized training in order to detect problems and improve the quality of training. Methods A total of 4484 clinical medical examinees from 2010, 2013 and 2017 in Liaoning province were investigated by questionnaire, from which 4412 valid questionnaires were collected and the total survey efficiency was 98.39％. The survey included the standardized patient (SP) examination, the small station test, the computer simulated case (CCS) examination and the clinical skill operation test station with parts 20 projects. Excel was used to sort and record the data. SPSS 10.0 software was used for statistical analysis. Results All parts of the practical skill assessment was reasonable. The examinees' satisfaction with the test is showing an upward trend year by year, up to 73.93％in 2017. In the standardized patients examination, the key points of the role play (including the fidelity and simulated authenticity of the physical signs) need be strengthened (14.84％ in 2010). Examinees thought the difficulty of computer simulation case examination is increasing year by year. More than 2/3 examinees evaluated the clinical skill operation test station set was reasonable and the difficulty was moderately. Conclusions We should further deepen the exploration of standardized patients assessment model; strengthen the medical humanities in training; improve the residents' clinical thinking;take examination as the guidance and standardize clinical training.
