Objective:Based on the theory of planned behavior (TPB), the exercise intervention program for breast cancer patients undergoing chemotherapy was constructed, and its application effect was preliminarily explored.Methods:A total of 116 patients receiving chemotherapy in the department of breast surgery from June to December 2021 in Shanxi Provincial Cancer Hospital were selected by purpose sampling method. The subjects were randomly divided into control group and experimental group by flipping a coin. The control group was given routine nursing, and the experimental group was given routine nursing on the basis of exercise intervention based on the theory of planned behavior. After three cycles of chemotherapy, the effects of the intervention were evaluated by piper Revised Fatigue Scale (RPFS), Exercise Self-efficacy Scale and Quality of Life Core Scale (EORTC QLQ-C30).Results:In the intervention stage, there were 2 cases in the experimental group and 3 cases in the control group lost. After the intervention, the total score and all dimensions (behavioral, emotional, sensory and cognitive) of cancer-induced fatigue in the experimental group were (2.30 ± 0.58), (2.21 ± 0.85), (2.32 ± 0.70), (2.66 ± 0.71) and (2.03 ± 0.58), which were lower than those in the control group (2.84 ± 0.44), (2.79 ± 0.60), (3.04 ± 0.75), (3.04 ± 0.60) and (2.53 ± 0.56), the differences were significant ( t values were 3.05-5.23, all P<0.05). The total scores of exercise self-efficacy and the dimensions of physical, psychological and social environment were higher than those of the control group ( t values were -7.63 - -3.31, all P<0.05). The scores of overall quality of life, physical function and emotional function were higher than those of the control group ( t = -3.48, -3.14,-2.34, all P<0.05), while the scores of fatigue and insomnia symptoms were lower than those in the control group ( t = 5.13, 3.14, both P<0.05). Conclusion:The exercise program based on the theory of planned behavior can improve the exercise self-efficacy of breast cancer patients undergoing chemotherapy, reduce cancer-related fatigue and improve their quality of life.

OBJECTIVE To explore the therapeutic effect and safety of Maiwei Yangfei Decoction(MWYF)in the treatment of idiopathic pulmonary fibrosis of qi-yin deficiency type.METHODS A total of 58 patients with idiopathic pulmonary fibrosis of qi-yin deficiency type were randomly divided into an experimental group and a control group with 29 cases in each group according to a 1:1 ratio.Two cases dropped out of the experimental group and three cases dropped out of the control group.The control group received standardized treatment of Western medicine,and the experimental group received MWYF on the basis of the treatment of the control group.The treatment course of both groups was 3 months.The TCM syndrome score,lung function,6-minute walking distance(6MWD),transcutaneous blood oxygen saturation(SpO2),high-resolution computed tomography(HRCT)score,St.George's respir-atory questionnaire(SGRQ)score and serum sialoglycoprotein antigen(KL-6)level of the two groups were compared before and after treatment.Blood routine and liver and kidney function of the two groups were detected before and after treatment,and the occurrence of adverse reactions during treatment was recorded.RESULTS After treatment,the total score of TCM syndrome of the two groups was significantly improved(P<0.01),and the experimental group was better than the control group(P<0.01);the DLCO%of the experi-mental group increased(P<0.05),and the experimental group was higher than the control group(P<0.05).The experimental group showed significant improvement in 6MWD,HRCT grid shadow,SGRQ symptom score and total score,and serum KL-6 level(P<0.05,P<0.01),which was better than the control group(P<0.05,P<0.01).No serious adverse events occurred in either group dur-ing the treatment.CONCLUSION MWYF combined with standardized Western medicine treatment can effectively improve the clini-cal symptoms of patients with idiopathic pulmonary fibrosis of qi-yin deficiency type,reduce the expression level of serum KL-6,and has a definite effect and good safety.
