ObjectiveTo evaluate the value of tissue mitral annular displacement (TMAD) in the assessment of left ventricular long axis systolic function and the relationship of obese degree with left ventricular long axis systolic function in patients with abdominal obesity.MethodsThirty-eight abdominal obesity cases and thirty-four healthy cases were investigated using echocardiography.The images of apical four-chamber view and apical two-chamber view were obtained,systolic mitral annular displacement (MADs),mid-point of mitral annular displacement(MAD-midpt),mid-point of mitral annular normalized displacement(MAND-midpt) and mid-point of mitral annular biplanar normalized displacement(MABNDmidpt) were measured by the technique of TMAD.Their characteristics between patients with abdominal obesity and healthy group were compared,and the relationship of waist-hip ratio(WHR) and related indexes of MAD were analyzed.ResultsIn abdominal obesity group,the MADs at the four site were significantly decreased compared with control group (P＜0.001,respectively),the MAD-midpt and MAND-midpt of apical four-chamber view and apical two-chamber view were significantly decreased compared with control group (P＜0.001,respectively).The WHR related with MABND-midpt independently by the analysis of partial correlation(r=-0.697,P=0.000).ConclusionsThe left ventricular long axis systolic function were damaged in patients with abdominal obesity.The technique of TMAD could quantitatively assess the left ventricular long axis systolic function in patients with abdominal obesity.

Objective: To explore school counselors' attitude and decision-making towards dual relationship and confidentiality. Methods: Totally 123 school counselors (27 males and 96 females, aged 20 to 60 years old, 41 primary and secondary counselors, 82 college counselors) filled up of self-designed Questionnaire for School Psychological Consultants on Dual Relationship and Confidentiality Rules, and the related factors which could influence the school counselors' attitude and their decision-making in dual relationship and confidentiality in the counseling work. Results:Totally 71.5％ (n =88) school counselors chose not to accept other relationships with students after counseling, 14.6％ (n = 18) school counselors chose to accept other relationships with students after counseling. The school counselors who had not accepted supervisioneasier to answer as "accept other relationship may raise clients self-esteem or feelings" than those had got supervision (P <0.05). The school counselor believed that the confidentiality agreement should be breached of the top 3(suicide attention, drug use and bad gangs). Counselors easier to breach confidentiality agreements on situation of students had suicide plans than situation of students had plans to run away from home(P <0.001). Conclusion:This study shows that two factors, including supervision and differential clients "issue may have effect on school counselors" attitudes and decision-making towards dual relationship and confidentiality situation in their counseling practice.
