To explore the effects on edema of the upper extremity,anxiety and depression in mammary cancer patients after operation by using needle warming moxibustion.Methods：A total of 80 mammary cancer patients after the operation admitted in The Second Affiliated Hospital of Heilongjiang University of Traditional Chinese Medicine from August 2016 to August 2017 were selected as research objects,and they were randomly divided into observation group(40 cases)and control group(40 cases).The control group was treated with oral diosmin,while the observation group was treated with needle warming moxibustion.After the treatment,the clinical efficacy of the 2 groups was analyzed.Effective indexes of the part 10 cm above the elbow,range of motion(ROM)of the shoulder joint,quality of life and psychologic status were compared between the 2 groups after the treatment.Results：After the treatment,the total clinical effective rate of the observation group was 92.50%,which was significantly higher than that of the control group 70.00%(P<0.05).After the treatment,the effective indexes of the part 10 cm above the elbow and the score of life quality were increased significantly in both 2 groups(P<0.05),and those in the observation group were higher than those in the control group at the same time,with significant difference(P<0.05).After the treatment,the ROM scores in the observation group were significantly increased(P<0.05).In the control group,only the anteflexion ratio in the shoulder joint ROM was increased significantly(P<0.05).And all the ROM ratios in the observation group were higher than those in the control group,with significant differences(P<0.05).The scores of SDS and SAS in both groups were decreased significantly(P<0.05),and those in the observation group were significantly lower than those in the control group,with significant differences(P<0.05).Conclusion：Needle warming moxibustion has significant efficacy in the treatment of mammary cancer after the operation.It can effectively alleviate edema,reduce the risk of depression and anxiety,and improve patients' quality of life,which is worthy for clinical application.
