RESUMO
Objective To explore the relationship between anhedonia,alexithymia and self-efficacy in college students.Methods 260 college students were tested with Snaith-Hamilton Pleasure Scale (SHAPS),Temporal Experience of Pleasure Scale (TEPS),20-item Toronto Alexithymia Scale (TAS-20)and General Self-Efficacy Scale (GSES).Results (1) Males showed obviously higher level of SHAPS scores (24.91±5.14) and lower level of anticipatory pleasure of TEPS (TEPS-ANT) scores(31.81±5.79)than females (22.97±5.34 and 33.36±5.71,respectively).(2)Significant difference existed between the high-scoring,the middle-scoring and the low-scoring anhedonia group in TAS factor 1 (difficulty in identifying feelings) and GSES (F=3.11,5.30,P＜0.05 or 0.01),the scores of TAS factor 1 (difficulty in identifying feelings) in high-scoring anhedonia group were higher than that in low-scoring anhedonia group (20.24±4.94 vs 18.10±5.07,P＜0.01),and the scores of GSES in high-scoring anhedonia group were lower than that in low-scoring anhedonia group (24.97±6.72 vs 27.90±4.37,P＜0.01).(3)The SHAPS scores were positively related to TAS factor 2 (difficulty in describing feelings) and factor 3 (externally oriented thinking) (r =0.18,0.27,both P＜0.01),negatively related to GSES scores(r=-0.33,P＜0.01).Both TEPS-ANT and consummatory pleasure of TEPS (TEPS-CON) were negatively related to TAS factor1 (difficulty in identifying feelings)scores (r=-0.22,P＜ 0.01;r =-0.15,P＜ 0.05),positively related to GSES scores (r =0.28,0.26,both P＜0.01).(4)Layer multivariate linear regression analysis showed that the SHAPS scores were significant predictors of the general self-efficacy(β=-0.33,P＜0.01).Conclusions The anhedonia in college students has a closely relationship with alexithymia and self-efficacy,college students with high anhedonia have high level of alexithymia and low level of self-efficacy.
RESUMO
<p><b>OBJECTIVE</b>To study the pattern extrahepatic arteriy supply to hepatocellular carcinoma and catheterization technique for interventional therapy.</p><p><b>METHODS</b>Routine celiac and superior mesenteric artery angiography was done before transcatheter arterial chemoembolization (TACE) for 78 collateral arterial pathways of 62 hepatocellular carcinoma patients. Super selective catheterization and transcatheter dual arterial chemoembolization (TDACE) to extrahepatic arterial and hepatic arteries were performed.</p><p><b>RESULTS</b>Extrahepatic blood supply was found in 43.1% of hepatocellular carcinoma patients. There was close correlation between extrahepatic arterial blood supply and location of tumor. Success rate of super selective extrahepatic artery catheterization was 71.8% by the combined use of RH, Cobra and SP catheters. Follow-up studies revealed reduction of tumor and complete dense deposition of lipiodol.</p><p><b>CONCLUSION</b>Ample extrahepatic arterial blood supply is found in hepatocellular carcinoma. Transcatherdual arterial chemoembolization is effective, necessary and feasible for hepatocellular carcinoma with extrahepatic arterial blood supply.</p>
