Alzheimer's disease (AD) is one of the major diseases that harmful to healthy elderly, and mild cognitive impairment (MCI) is the early clinical stage of AD. There is a lag in the clinical diagnosis of both diseases. An objective and reliable auxiliary diagnostic method is urgently needed to provide early diagnosis and differential indicators for AD and MCI, to predict the probability of individuals suffering from AD and MCI transforming into AD, and to reduce the overall incidence of AD and reduce the huge medical and economic burden for the country and society. Event-related potential is widely used in AD and MCI, and the resolution at the millisecond level can truly reflect the time course of cognitive processing and the degree of impairment of cognitive function in patients. In this study, we investigated the differences in the amplitude and latency of ERP components in healthy elderly, MCI and AD patients, and the correlation between ERP components and cognitive impairment. Early N170 and P200 showed high sensitivity and specificity in differentiating MCI from healthy elderly or MCI from AD. The late perception-related ERPs also showed high sensitivity and specificity in differentiating healthy elderly from MCI/AD. The differences in ERPs between MCI and AD may be related to the etiology, the degree of disease progression and the site of brain damage. The specific brain mechanism still need to be further explored and will be the focus of future research. With the progress of the research, the relationship between the specific ERP manifestations and the mechanism of brain injury as well as the impairment of cognitive function will be more clear. It is believed that the application of ERP in clinical will bring more benefits to AD and its early clinical MCI.

Objective To explore the difference of social support,self-esteem and marital quality between urban and rural areas and discuss the impact on each other.Methods Chinese marital quality questionnaire,selfesteem scale (SES) and social support rating scale were used to test 386 urban and rural married residents.Results ①The results of descriptive statistics showed that marriage quality,social support and self-esteem of urban and rural residents were (318.46±37.41),(42.44±5.84) and (30.65 ± 3.95) respectively.②There was no significant difference among social support,self-esteem and marital quality in different gender(t =0.41,-0.16,0.03,P> 0.05),but had significant difference between urban and rural areas(t=2.83,3.91,5.24,P<0.01).There were significant differences between social support and marital quality in different age structures(t=5.22,3.85,P<0.05).There were significant differences between social support and self-esteem in different educational level (t =3.48,4.16,P<0.01).③Social support,subjective support,objective support and marital quality had positive correlation (r=0.114~0.394,P<0.05).The degree and character compatibility,communication between couples,resolve conflicts are positively related to support (r=0.308~ 0.476,P<0.01).④Stepwise multiple regression analysis and structural equation modeling analysis showed that self-esteem played partial intermediary role between social support and marital quality(37.7%),which could explain 26.8% of marital quality.The social suptort and self-esteem could better predict marital quality.Conclusion The higher social support and self-esteem are,the higher marital quality is.Social support can directly affect the marital quality and indirectly affect marital quality through self-esteem.

ObjectiveTo explore the influences of parental rearing pattern and adult attachment on narcissism of college students.Methods 344 college students from two universities in Hebei Province were sampled randomly and tested by the Chinese version of EMBU,the Narcissistic Personality Inventory and the Experiences in Close Relationships Inventory (ECR) in Chinese version.Results ( 1 ) The whole score of overt narcissism correlated with paternal warming,punishment,interference,rejection and maternal warming( r =0.163,0.130,0.184,0.109,0.206),but not with adult attachment; covert narcissism correlated with paternal punishment,over-interference,rejection,over-protection,maternal over interference and protection,rejection,and punishment,and anxiety and aviodance of adult attachment positively ( r =0.135,0.169,0.210,0.123,0.220,0.194,0.215,0.183,0.269).(2) The parental reaming pattern affected overt narcissism directly,while that affected covert narcissism directly with adult attachment,and indirectly through adult attachment.ConclusionCotraditory rearing patterns between father and mother lead to overt narcissism,and negative rearning patterns lead to covert narcissism with the mediator role of adult attachment.
