A rapid and simple ultra performance liquid chromatographic method for determination the specific migration of bisphenol A diglycidyl ether ( BADGE ) , bisphenol F diglycidyl ether ( BFDGE ) and their derivatives in food simulants was developed. Water, 3% acetic acid, 10% ethanol and sunflower oil were used as food simulants to simulate the specific migration of bisphenol diglycidyl ethers from interior coating of food cans after 10 days storage at 60℃. After the migration period, the aqueous food simulants were directly measured without any further purification, while the sunflower oil simulant was extracted by acetonitrile followed by cleaning up using solid phase extraction. Among the migration process, BADGE and bisphenol A (3-chloro-2-hydroxypropyl)glycidyl ether (BADGE·HCl) migrated into aqueous simulants were hydrolysed into bisphenol A bis ( 2, 3-dihydroxypropyl ) ether ( BADGE · 2H2 O ) and bisphenol A ( 3-chloro-2-hydroxypropyl) (2,3-dihydroxypropyl) ether (BADGE·H2O·HCl), respectively. However, BADGE and BADGE·HCl migrated into sunflower oil were not hydrolysed. The calibrating curves showed a good linearity from 0. 05 to 10 mg/L for all the 9 target compounds. The detection limits of the method for aqueous food simulants and sunflower oil stimulant were 5μg/L and 20μg/kg, respectively. The method was applied to the determination of bisphenol diglycidyl ethers migrated from 10 kinds of food cans which were intended to contact with food. The results indicate that BADGE and its derivatives were detected at 5 of the cans, and the specific migration of BADGE(or BADGE·2H2O)and BADGE·HCl(or BADGE·H2O·HCl)in 1 cans even exceed the responding limitation regulated in EC/1895/2005 .

Objective To explore the clinical effect of psychological nursing pathway for patients with hepatocellular carcinoma (HCC) who are receiving 125I particle implantation therapy.Methods A total of 130 HCC patients,who were scheduled to receive 125I particle implantation therapy,were randomly and equally divided into the study group and the control group with 65 patients in each group.Traditional routine psychological nursing method was conducted for patients of the control group,while routine psychological nursing that was based on psychological nursing pathway was carried out for patients of the study group.The patient's conditions of both groups were evaluated by using self-rating anxiety scale (SAS),trait coping style questionnaire (TCSQ) and the quality of life assessment scale (SF-36).The results were statistically analyzed with t test.Results After nursing intervention,SAS scores of the study group and the control group were (43.76±6.25) and (46.16±7.19) points respectively,the difference between the two groups was statistically significant (t=-3.92,P<0.001).The PC and NC values of the TCSQ score in the study group were (41.61±4.82) points and (20.53±5.88) points respectively,while those in the control group were (37.32±4.62) and (22.80±6.93) respectively,the differences between the two groups were statistically significant (t=5.944 and t=-3.316 respectively,P<0.01).One month after discharge,the mental health scores of the study group and the control group were (74.58±8.68) points and (71.53±8.16) points respectively,the emotion function scores were (79.46±10.05) points and (75.13±15.09) points respectively,and the differences in both mental health score and emotion function score between the two groups were statistically significant (P<0.05).Conclusion Standardized psychological nursing pathway can make nurses more clear about the content of psychological nursing work and enable nurses to actively plan and complete psychological nursing care measures,so that patients can get prospective,individual and comprehensive psychological care to alleviate his or her negative emotion,and to improve the quality of life.
