Objective:To explore the application effect of music relaxation therapy based on Swanson's caring theory in breast cancer patients.Methods:A total of 180 breast cancer patients who were admitted to Shanxi Provincial People's Hospital from February 2018 to January 2020 were selected by the convenient sampling method. They were divided into the control group ( n=92) and the observation group ( n=88) according to the random number table method. The control group was given routine nursing, and the observation group was given music relaxation therapy based on Swanson's caring theory. The scores of Medical Coping Modes Questionnaire (MCMQ) and Herth Hope Index (HHI) were compared between the two groups before and after intervention. Results:Before intervention, there were no statistically significant differences in HHI and MCMQ scores between the two groups ( P>0.05) . After the intervention, the HHI score of the observation group was higher than that of the control group, and the difference was statistically significant ( P<0.05) . The face dimension score of the observation group was higher than that of the control group and the yield and avoidance dimension scores were lower than those of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Music relaxation therapy based on Swanson's caring theory can effectively improve the coping style of breast cancer patients and improve their hope level.

Objective:To explore the application effect of ADOPT mode in breast cancer patients with peripherally inserted central catheter (PICC) catheterization.Methods:Using the convenient sampling method, a total of 248 breast cancer patients with PICC catheterization who were admitted to Shanxi Provincial People's Hospital from June 2018 to June 2020 were selected as the research objects. The patients were divided into the observation group ( n=124) and the control group ( n=124) using the random number table method. The patients in the control group were given routine nursing care, while the patients in the observation group were given the ADOPT model on the basis of the nursing care in the control group. The incidence of PICC complications was compared between the two groups. The scores of Exercise of Self-Care Agency Scale (ESCA) , Cancer Fatigue Scale (CFS) and Quality of Life Questionnaire Breast Cancer Module 23 (QLQ-BR 23) were compared between the two groups before and after 3 months of intervention. Results:The number of unplanned extubation cases in the observation group was lower than that in the control group ( P<0.05) . After 3 months of intervention, scores of ESCA and QLQ-BR 23 function scale of the observation group were higher than those of the control group. And the scores of each dimension of the CFS, the QLQ-BR 23 symptom scale and score of the each item were lower than those of the control group, all the differences were statistically significant ( P<0.05) . Conclusions:The ADOPT model has a good effect on reducing the incidence of unplanned extubation in breast cancer patients with PICC catheterization, which can effectively improve the self-care ability and quality of life of patients and relieve cancer fatigue in patients.

Arachidonic acid, as an important polyunsaturated fatty acid, is identified as potential food additives or pharmaceuticals for their biological activities. In recent years, arachidonic acid production by Mortierella alpina is becoming a research highlight. The prophase relevant researches focused on the mutagenic breeding and fermentation optimization. With the depth of investigation, the advancement concerning pathway for the biosynthesis of arachidonic acid in Mortierella alpina has been made. In this review, we summarized the prophase work briefly. Mainly, we discussed the biosynthesis pathway of arachidonic acid, the key enzymes, the construction of transformation system and the genetic modification. In addition, the prospect of microorganism arachidonic acid production is put forward.
