ABSTRACT
Objective:To explore the therapeutic effect of psychological and drug intervention on anxiety and depres‐sion in patients after coronary artery bypass graft (CABG) .Methods :A total of 115 patients performed CABG were randomly divided into combined intervention group (n=60) and routine nursing group (n=55) .During peropera‐tive period ,combined intervention group received psychological intervention ,flupentixol and melitracen tablet and sertraline based on routine nursing .A total of 25 matching normal people were selected from community and regar‐ded as normal control group ,scores of Zung self‐rating anxiety scale (SAS) and self‐rating depression scale (SDS) were evaluated and compared among three groups before and after operation .Results :Before intervention ,there were no significant difference in standard scores of SAS and SDS between combined intervention group and routine nursing group ( P > 0.05) ,but they were all significantly higher than those of normal control group , P < 0.01 all . After operation ,standard scores of SAS and SDS in combined intervention group were significantly lower than be ‐ fore operation ( P < 0.01 both) ,and they were significantly lower than those of routine nursing group [SAS : (41.31 ± 6.13) scores vs .(51.35 ± 8.95) scores ,SDS : (40.20 ± 5.80) scores vs .(51.22 ± 8.78) scores , P < 0.01 both] . Conclusion :Psychological combined drug intervention could significantly relieve anxiety and depression in patients after coronary artery bypass graft ,which is helpful for improving postoperative prognosis .
ABSTRACT
Objective To study the effect of Neuregulin-1 (NRG) on rat heart failure(HF) after myocardial infarction,and to investigate the underlying mechanism involving in NRG-mediated cardioprotection.Methods 60 adult Wister rats underwent sham operation (n=12) or coronary ligation (n=48) to induce HF.Four weeks after ligation,28 animals with HF were randomly divided into NRG group (rats received rhNRG-1 10 μg · kg-1 · d-1 intravenously for 10 days) or HF group (rats received an equal volume of water intravenously for 10 days).Left ventricular function was detected by echocardiography.Mitochondrial ultrastructure in non-infarcted myocardium was observed by transmission electronic microscopy.Cell apoptosis was detected by terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) assay.Mitochondrial membrane potential was measured by immunofluorescence method.Caspase-3 activity was determined by commercial kit.The expression of cytochrome C protein in cytoplasm was detected by Western blot.Results Compared with HF group,the left ventricular end-systolic diameter was decreased,and left ventricular ejection fraction and fractional shortening were increased in NRG group (P＜0.05 or 0.01).Apoptosis index was reduced inNRG group as compared with HFgroup [(18.1±3.0)％ vs.(11.9±1.4)％,P＜0.01].Mitochondrial membrane potential was increased and the release of cytochrome c in cytoplasm was reduced in NRG group as compared with HF group [(249.8±7.4) mV vs.(222.2±7.5) mV,(0.356±0.024) vs.(0.664±0.085),both P＜0.01].Caspase-3 activity was decreased in NRG group as compared with HF group (P＜0.01).Conclusions NRG attenuats mitochondrial stress and inhibits myocardial cells apoptosis in heart failure rats after myocardial infarction,which may play an important role in the cardioprotection by NRG.
ABSTRACT
ObjectiveTo explore the relationship between the alexithymia and impact of event of the prison male offenders.Methods267 male inmates in one prison of Tangshan and 99 men from students and general workers have been tested with Toronto Alexithymia Scale (TAS-26) and Impact of Event Scale-Revisod( IESR).Results ① The alexithymia scores of prison male offenders were more higher except for the factor Ⅰ (Prion:18.62 ± 3.61 ; general:18.00 ± 3.57 ) and factor Ⅲ ( prion:14.38 ± 3.06 ;general:14.96 ± 3.34).And there were significant differences in factor Ⅱ ( Prison:22.26 ± 3.96 ; general:19.72 ± 3.34 ),factor Ⅳ ( prison:22.38 ± 4.20;general:21.03 ± 4.03 ) and the total score (prison:77.65 ±7.22;general:73.71 ±8.32) (P＜0.01).② Sex offenders'alexithymia degree was the heaviest ( 79.90 ± 5.00 ) and violence perpetrator' degree was the lightest (77.55 ±7.43),but there was no significant difference among the three subjects(P＞0.05).There were significant differences in the evade dimension and the total score in impact of evens between the three different type prison male offenders.③There were negative eorrehtions between factor Ⅲ and factor Ⅳ of alexithymia and every dimension of impact of events( r =-0.14 ～ -0.22,P＜ 0.05),there were positive correlations between factor Ⅰ and factor Ⅱ of alexithymia and every dimension of impact of events( r =0.14 ～ 0.43,P ＜ 0.05 ).ConclnsionThe degree of alexithymia in prison male offenders is higher than the general men.The violent male offenders are served more impact of events.The higher the degree of alexithymia of the prison male offenders,the more impaction of the event they served.
