Objective To explore the effects of family and telephone follow-up on quality of life of the patients with tota1 hip arthroplasty(THA).Methods One hundred and twelve patients with THA were randomly divided into experiment group and control group with 56 cases in each group.The experiment group was treated with rehabilitative instruction by family and telephone follow-up.The control group was treated with outpatient follow-up after leaving the hospital.The living quality in both groups were compared by the medical outcomes study 36-item short-form health survey(SF-36 QOL)one year after leaving the hospital.Results One-year after leaving the hospital,the total score and demension score of experiment group were better than those of the control group.There was significant difference between the control group and in experiment group(P<0.05).Conclusion Family and telephone follow-up is an effective implementation for THA patients to accomplish physiological functional recovery and promote the quality of life.

Objective To investigate the changes of platelet aggregation rate and platelet surface CD 41+CD62P+ expression af-ter clopidogrel discontinuation in the patients with percutaneous coronary interventions (PCI)) .Methods The platelet aggregation rates and platelet surface CD41+CD62P+ in 52 PCI patients with oral clopidogrel for near 12 months and discontinuation soon were measured before clopidogrel therapy(T0 ) ,in 1 week after clopidogrel therapy(T1 ) ,1 week before clopidogrel discontinuation(T2 ) , 1 week(T3 ) and 1 month after clopidogrel discontinuation (T4 ) .Results Compared with T0 ,the platelet aggregation rate and the expression of platelet CD41+CD62P+ at T1 were significantly decreased ,the difference showing statistical significance (P<0 .05) , which at T2 maintained the lower levels ;which at T3 were increased ,which at T4 were recovered to those at T0 .The platelet aggre-gation rates at various time points were (44 .20 ± 18 .36)% ,(25 .38 ± 12 .10)% ,(23 .74 ± 8 .15)% ,(51 .79 ± 10 .55)% and(45 .97 ± 16 .42)% respectively ,and the positive rates of CD41+ CD62P+ were(12 .96 ± 11 .48)% ,(3 .93 ± 3 .33)% ,(4 .72 ± 3 .14)% , (13 .90 ± 10 .38)% and(10 .84 ± 8 .13)% ,respectively .Conclusion In the patients treated with 12-month clopidogrel after PCI ,the platelet aggregation rate and the CD41+CD62P+ positive rate are mildly increased at 1 week after clopidogrel discontinuation and gradually returned to the level before discontinuation at 1 month after clopidogrel discontinuation .
