Abstract:Objective: To investigate the effects of Shenqifuzheng Injection on quality of life and immune function in patients with chemotherapy of lung cancer. Methods: We analyzed 74 cases of lung cancer patients randomly divided into treatment group (Shen Qi Fu Zheng group), positive control group (Addie injection group) and blank control group. Results: In terms of total effective rate, the treatment group was higher than the blank group, the difference was significant (P <|0.05). After treatment, the CD3+, CD4+, CD4+/CD8+and NK cells were no difference between the treatment group and the control group (P>0.05), While the control group after treatment, CD3, CD4+, CD8+, CD4+/CD8+ ratio were lower than before treatment (P<0.05 or P<0.01).After treatment, the CD3+, CD4+, CD4+/CD8+ ratio and the blank control group had statistical significance with the treatment group (P<0.05).Conclusion: Shen Qi Fu Zheng Injection combined with chemotherap can improve the curative effect and the immune function in the lung cancer patients.
