Chinese Journal of Clinical Psychology 1993;0(01):-
Objective: To study the relationships among attributional style, self-efficacy and subjective well-being(SWB). Methods: 269 college students participated the study. Attributional Style Questionnaire , Self-efficacy Questionnaire and Subjective Well-being(SWB) Questionnaire were applied to the college students. Results: ① Attributional style predicated SWB, but three dimensions (internality-externality; whole-part; controllability-uncontrollability)of negative events were significant negative predicators of SWB. ② Self-efficacy was a significant positive predicator of SWB. ③ There were no differences in SWB between sexes and specialities. ④ There were significant differences in SWB between students with different self-efficacy levels, and the SWB of high self-efficacy group was better than that of the low self-efficacy group. Conclusion: College students'attributional style and self-efficacy impact their subjective well-being.Educators should cultivate students's positive attributional style and enhance their self-efficacy.

Objective To investigate the protective effect and mechanisms of NF-?B decoy oli- godeoxynucleotides(ODNs)on rat liver graft following ischemia-reperfusion injury.Methods Ani- mals were randomly divided into 3 groups(n=8 in each group):control group,ischemia-reperfusion (IR)group,and decoy ODNs group,in which donor grafts were transfected with 120?g NF-?B decoy ODNs before graft procurement.Following 2 h of reperfusion,Kupffer cells(KCs)were isolated,and NF-?B biding activity was detected with electrophoretic mobility shift assay(EMSA),and TNF-?、IL- 6 mRNA expression was assayed by using RT-PCR method.Meanwhile,the liver and serum samples were collected,the histopathologic change of liver was examined by light microscope,and liver func- tion was analyzed.Results The NF-?B biding activity,TNF-?,IL-6 mRNA expression,and the ALT,TBIL levels in serum were significantly increased following 2 h of reperfusion in IR group as compared with those in control group(P<0.01).A large amount of degeneration and necrosis in hep- atocytes accompanied with obvious congestion in hepatic sinusoid occurred.However,these tested in- dexes were significantly ameliorated in decoy ODNs group as compared with those in IR group(P<0.01),and the architecture of hepatic lobules was remained.Conclusions KCs NF-?B activation fol- lowing reperfusion plays an important role in IRI in liver transplantation.Decoy strategy shows appar- ent effect on suppression of NF-?B activation,and thus inhibits the production of downstream cyto- kines,which protects the liver graft from IRI.

Objective To evaluate the effect of 3-dimmentional conformal radiotherapy (3-DCRT) for mediastinal metastasis from esophageal carcinoma after surgery.Methods Sixty-three such patients were treated by 3-DCRT. Tumor diameter was: cm 20 patients. Positive supraclavicular lymph node was found in 9 patients. The number of tumor at the upper right, upper left and upper median mediastinum was 27, 27 and 20. All patients received 3-DCRT to the dose of 40?Gy (2?Gy/f, 5f/w), after resetting of portals, the dose was boost to 64~70?Gy by 3?Gy/f, 5f/w. Dose of the patients who had been irradiated was boosted to 50?Gy without further positioning. Results Complete response rate and partial response rate were 43% and 48% one month after the treatment was concluded,with no progression of disease. The 1-, 2- and 3-year survival rates were 75%, 43% and 15%. Conclusions Three-dimmentional conformal radiotherapy, with little side-effects, can markedly improve the local control rate and suvival rate of patients with mediastinal metastasis from esophageal carcinoma after surgery.
