ABSTRACT
cFos is one of the most widely-studied genes in the field of neuroscience. Currently, there is no systematic database focusing on cFos in neuroscience. We developed a curated database—cFos-ANAB—a cFos-based web tool for exploring activated neurons and associated behaviors in rats and mice, comprising 398 brain nuclei and sub-nuclei, and five associated behaviors: pain, fear, feeding, aggression, and sexual behavior. Direct relationships among behaviors and nuclei (even cell types) under specific stimulating conditions were constructed based on cFos expression profiles extracted from original publications. Moreover, overlapping nuclei and sub-nuclei with potentially complex functions among different associated behaviors were emphasized, leading to results serving as important clues to the development of valid hypotheses for exploring as yet unknown circuits. Using the analysis function of cFos-ANAB, multi-layered pictures of networks and their relationships can quickly be explored depending on users’ purposes. These features provide a useful tool and good reference for early exploration in neuroscience. The cFos-ANAB database is available at www.cfos-db.net.
ABSTRACT
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 role of college students' emotion regulation strategies in the relationship between emotion experiences and physical health.Method A total of 2 000 college students from a college in Hebei Province were tested randomly with the depression anxiety stress scale-21 (DASS-21),the emotion regulation questionnaire (ERQ) and the EuroQoL five-dimension questionnaire(EQ-5D).Results (1) Depression,anxiety and stress and expression suppression of male students (1(0,5),1(0,6),2(0,7),16.61±5.34,respectively) were higher than those of females(0(0,2),1(0,3),1(0,4),15.68±5.l0,respectively) (Z=-6.162,-3.108,-2.846,t=3.814,P＜0.01);and cognitive reappraisal,visual analogue scales (EQ-VAS) and EQ-5D value indexes(EQ-5D) of male students(27.74±7.56,81.17 ± 18.29,0.94 ± 0.15,respectively)were lower than those of females (28.69 ± 6.34,84.23 ± 16.43,0.96 ± 0.11,respectively) (t=-2.967,-3.812,-3.837,P＜0.01).(2) The scores of depression,anxiety and stress were positively correlated with expression suppression (r=0.096,0.080,0.066,P＜0.01),and negatively correlated with cognitive reappraisal(r=-0.176,-0.160,-0.174,P＜0.01) and EQ-VAS (r=-0.410,-0.437,-0.422,P＜0.01).(3) Cognitive reappraisal played a moderating role in the effect of stress on physical health (R2 =0.191,P＜0.01);and expression inhibition exerted a positive moderating role in that of depression on physical health (R2 =0.163,P＜0.01).Conclusion College students' emotion regulation strategies play a moderating role in the effect of emotional state on physical health.
ABSTRACT
Objective:To analyze the reasons of early failure of the PHILOS in proximal humerus frac-tures.Methods:From Nov.2010 to Nov.2014,there were 117 patients with humerus fractures treated with PHILOS locking plate in Department of Orthopaedics,Xuanwu Hospital.All of the patients were treated with the plate by open reduction internal fixation,and we analyzed these cases retrospectively. After the operation,we removed the drainage tube within 48 h,and the patients were allowed to do the passive motion 3 days after the surgery if the X-Ray showed the plate and screws were reliable.Eight ca-ses failed within 4 weeks after the operation.We analyzed the reasons of the failure.Results:The rate of the failed cases was 6.83%(8 /117).The average age was 72.4(66 -82)years.In the 8 failed cases, 3 were on the right side,and the other 5 on the left side.As for the reason of the fractures,2 cases were because of car accidents,and the other 6 because of daily life injury.According to the Neer classifica-tion,3 cases were 2-part fractures,and the other 5 3-part fractures.Three cases were total failure,and the other 5 partial failure.All the 8 failed cases failed within 4 weeks after the operation,of which 1 was on the sixth day after surgery,the other 7 2 to 4 weeks after the surgery.The 3 totally failed cases were treated by removing the screws and plates,the other 5 by conservative methods.All of the cases were malunion at the end.Conclusion:The early failure of the PHILOS locking plate in proximal humerus fractures is related to the bad reduction during the operation,the loss of medial cortex support,the limi-tation of screw length,the osteoporosis and the improper rehabilitation after operation.It is very important to do good preoperative plan for a surgeon.During the operation,we should try our best in the fracture reduction,use the appropriate plate and screws,and then pay attention to the rehabilitation after the operation.After all of this,the rate of failure may be decreased.

ABSTRACT
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.
ABSTRACT
ObjectiveTo explore the influence of narcissism of mothers of middle school students on maternal consciousness and their rearing patterns,and to provide theoretical support for family education.Methods361 pairs middle school students and their mothers were sampled randomly and tested by middle school students' mother maternal consciousness scale and the narcissistic personality Inventory for the mothers,and the mother's subscale of EMBU for the students respectively.The data were analyzed by ANOVA,product-moment correlation and path analysis.Results 1 ) Overt narcissism had significant differences among different levels of income(F=6.501,P＜0.001 ); 2)overt narcissism was correlated positively with emotional warmth and understanding of mother and mother' s over-interference,over-protection ( r =0.121,0.126,P ＜ 0.05 ) ; covert narcissism was correlated negatively with maternal consciousness and emotional warmth and understanding of mother,and positively with over-protection,refusal and deny,and severe punishment; 3 )narcissism of mothers not only would influence their rearing patterns through maternal consciousness indirectly( β=0.319,P=0.000),but would influence that directly ( covert narcissism:β =0.281,P =0.000 ; overt narcissism:β =- 0.278,P =0.000) ; and overt narcissism had positive effect,while covert narcissism had negative effect.ConclusionNarcissism of mothers of middle school students influences maternal consciousness and rearing patterns,and effect of overt narcissism is positive,and that of covert narcissism is negative.So it is important to perfect mother's character for ameliorating their rearing pattern.
