Objective To screen out the individuals at high cognitive risk by using the weakest link theory,and explore the characters of the cognitive emotion regulation.Methods 600 undergraduate students were tested with cognitive style questionnaire,general social and academic hassles scale,center for epidemiologic studies depression scale,and cognitive emotion regulation questionnaire.Results There were significant differences between individuals of high and low cognitive risk in self-blame (13.32 ± 2.12) vs (12.45 ± 2.27),rumination,catastrophizing,blaming others,positive refocusing and positive reappraising.Catastrophizing,generality,rumination,positive reappraising,stress,self-blame,and self could predict 34.2％ of depression.Conclusion There are differences between individuals of high and low cognitive risk in cognitive emotion regulation.Catastrophizing,generality,rumination,positive reappraising,stress,self-blame,and self are the main predictors of depression.

ObjectiveTo explore the correlations of university students'love style,dysfunctional attitude,and love satisfaction and life satisfaction.MethodsA total of 552 college students were assessed with relationship assessment scale(RAS),dysfunctional attitude scale(DAS),loving style scale(LSS) and life satisfaction index-A (LSIA).Results ( 1 ) The score of RAS of erotic loving style was ( 27.85 ± 4.624 ) significantly higher than the counterparts of the ludus loving style,which was (23.89 ± 4.061 ) (P ＜ 0.01 ).(2) There were significantly positive correlations among eros loving style,storge loving style,agape loving style,pragma loving style,life satisfaction and loving satisfaction,and negative correlations among Ludus loving style,dysfunctional attitude and loving satisfaction.(3)Loving satisfaction could be significantly predicted by dysfunctional attitude,eros loving style,ludus loving style,pragma loving style and storge loving style.ConclusionsLoving style and dysfunctional attitude can significantly predict loving satisfaction.

Mechanical circulatory support(MCS)devices have been widely used in the treatment of heart failure(HF)patients,but the infection problems caused by percutaneous cables for power transfer severely reduces the long-term survival rate of patients.The application of wireless power transfer(WPT)technology to MCS devices,and the realization of wireless power supply and full implantation of the devices is an effective means to reduce infection.WPT technology eliminates the need for percutaneous cables to transmit power,eliminates the infection problem caused by percutaneous cables,and improves the quality of life for patients,which is a more ideal power transmission method for MCS devices.The research progress of four WPT technologies,including transcutaneous energy transfer(TET),free-range resonant electrical energy delivery(FREE-D),coplanar energy transfer(CET)and ultrasound transcutaneous energy transmission(UTET),and the application of WPT technologies in 18 MCS devices were reviewed.The advantages and disadvantages of the existing WPT technologies and the bottlenecks in the application to MCS devices were discussed,and the future development direction was prospected,so as to provide a reference for the subsequent research on WPT for MCS devices.
