Objective To analyze the correlation of carotid artery stenosis(CAS)with postoperative cognitive dysfunc?tion(POCD)in patients who underwent off-pump coronary artery bypass grafting(OPCABG). Methods Between March 2014 and October 2014, a total of 157 patients who underwent OPCABG in our hospital were enrolled and divided into POCD group and non-POCD group according to their performance respondent to MMSE questionnaire survey conducted 5 days before operation. LOTCA questionnaire survey was conducted at the first day and 7th days pre-and post-operation re?spectively in order to investigate the influence of CAS on POCD in patients. Results The incidence of POCD was 30.6%(48 out of 157). Advanced age, diabetes,cultural level,carotid artery stenosis, Hb level after operation, score of LOTCA question?naire survey conducted before surgery,time of respirator and the time spend in ICU were significant predictive factors for POCD. However, multivariate logistic regression analysis showed that age, CAS and the time spend in ICU were independent risk factors for POCD, especially CAS(OR=5.078,95%CI:2.211-11.662, P<0.001). Patients with severe CAS suffer from a significant decline in cognitive function on space, time, action and ideation. Conclusion CAS is a predominant risk factor for POCD in patients undergoing OPCABG.

Objective To explore the relationship among peer relationship,self-consciousness and social anxiety in HIV-infected children. Methods Peer Relationship Scale,Piers-Harris Children's Self-con-cept Scale and Social Anxiety Scale for Children were applied to 126 HIV-infected children. Results The score of peer relationship was 53. 0(45. 0,62. 0),the score of self-concept was 52. 0(42. 0,60. 0),and the score of social anxiety was 6. 0(2. 0,9. 0). Peer relationship was positively correlated with social anxiety( r=0. 196,P=0. 029) and negatively correlated with self-consciousness(r=-0. 628,P<0. 01). Self-conscious-ness was negatively correlated with social anxiety(r=-0. 504,P<0. 01). Bootstrap analysis showed that self-consciousness played a complete mediating role between peer relationship and social anxiety,and the media-ting effect value was 0. 377. Conclusion Peer relationship,self-consciousness and social anxiety are closely related. Furthermore,self-consciousness plays a complete mediating role between peer relationship and social anxiety in HIV-infected children.
