Objective,2,To observe the efficacy of Buyang Huanwu Decoction combined with moxibustion in the treatment of advanced lung cancer in the elderly.,Methods,2,70 patients who met the inclusive criteria were randomly divided into treatment group and control group， with 35 patients in each group. All patients were treated with anti-tumor and symptomatic support. The treatment group was treated with Buyang Huanwu Decoction and mild moxibustion for 6 weeks. The efficacy of the two groups and the scores before and after treatment with traditional Chinese medicine syndromes， T-lymphocyte subsets in peripheral blood， quality of life scale scores of lung cancer patients（FACT-L），coagulation and platelet indexes（prothrombin time， PT）， activated partial thromboplastin time（APTT）， fibrinogen（FIB）， D-dimer（D-D）， platelet（PLT） and safety were compared.,Results,2,After treatment， the Traditional Chinese medicine syndrome score in the treatment group was（17.14 ± 2.59）points， which was lower than that in the control group（21.14 ± 2.84）points（,P,<,0.05），the total effective rate of the treatment group（80.0%） was better than that of the control group（51.4%）， with a statistically significant difference（,P,<,0.05）. After treatment， the ratio of CD8,+,T lymphocytes in the treatment group was lower than those in the same group before treatment and the control group after treatment， and the other indexes were higher than those in the same group before treatment and the control group after treatment， with the difference statistically significant（,P,<,0.05）.There was no significant difference in the control group before and after treatment（,P,>,0.05）. After treatment， except for social/family situation scores， the other scores in the treatment group were higher than those in the treatment group before treatment and the control group after treatment（,P,<,0.05）， while there was no significant difference in the scores of the control group before and after treatment（,P,>,0.05）.After treatment， APTT and PT in the treatment group were prolonged， which were higher than those in the same group before treatment and the control group after treatment（,P,<,0.05）， FIB， PLT， and D-D were lower in the treatment group than those in the same group before treatment and the control group after treatment（P,<,0.05）. There was no significant difference in the above indexes before and after treatment in the control group（,P,>,0.05）.,Conclusion,2,Buyang Huanwu Decoction combined with mild moxibustion can regulate the body's immune function， relieve hypercoagulable state， improve Qi-deficiency and blood stasis syndrome， andenhance the quality of life.
