Objective:To analyze the effect of comprehensive nursing education on anxiety, depression, quality of life and survival of patients with hepatocellular carcinoma (HCC) after surgery.Methods:A total of 136 HCC patients were randomly divided into two groups: general nursing education group and comprehensive nursing education group. The comprehensive nursing education group carried out 12 months of health belief education, psychological care, care activities and telephone condolence. The routine nursing group received basic education for 12 months. The changes of anxiety and depression were assessed by hospital anxiety and depression scale (HADS). The quality of life (QOL) of participants within 12 months was assessed using the European research and treatment cancer quality of life questionnaire (QLQ-C30). The 3-year survival of the two groups was compared.Results:There was no significant difference between the two groups in baseline data. At the 9th and 12th month, the HADS-A score of the comprehensive nursing education group was significantly lower than that of the general nursing group ( P< 0.05). In the 12th month, the overall health of QLQ-C30 in the comprehensive nursing education group was better than that in the general nursing group ( P<0.05). The QLQ-C30 function score of the comprehensive nursing education group at the 12th month was better than that of the general nursing group ( P<0.05). There was no significant difference in QLQ-C30 symptom scores between the two groups at all time points ( P>0.05). The overall survival of the patients in the comprehensive nursing education group was better than that in the general nursing group ( P=0.026). Conclusion:the comprehensive nursing education can reduce the anxiety and depression of HCC patients after surgery, and can improve their quality of life and survival.

A new biosensor was prepared based on conductive polymer poly ( 3 , 4-ethylenedioxythiophene ) ( PEDOT) and 1-pyrenebutanoic acid ( PBA) through π-π stacking, as well as hematin associated with PBA through coordinate bonds of Zr4+ and carboxyl group. Its stability and sensitivity were examined by cyclic voltammetry ( CV) , electrochemical impedance spectroscopy ( EIS) and current-time ( i-t) method. A pair of well defined and quasi-reversible redox peaks was observed when GCE/PEDOT/PBA/hematin was tested by CV in PBS without oxygen. The electron transfer rate constant was estimated to be 4. 8 s-1 . Results indicated that the PEDOT film enhanced the electron transfer process of hematin. When the i-t method was used to detect the response of biosensor to catechol with different concentrations, it displayed a linear response for the reduction of catechol in the range of 0. 5-200 μmol/L. The linear equation was i=0. 018C+0. 006 ( R=0. 9998), and the detection sensitivity was 0. 258 μA (μmol/L· cm2) with a detection limit of 0. 33 nmol/L (S/N=3). The results illustrate that the GCE/PEDOT/PBA/hematin biosensor is very sensitive and stable.
