Objective. To investigate the effect of Danggui Beimu Kushen Pills on renal cell carcinoma patients undergoing laparoscopic radical resection and their effects on renal function and immune function. Methods. 106 patients with renal cell carcinoma who underwent retroperitoneal laparoscopic radical surgery in our hospital from March 2015 to February 2017 were selected, and they were divided into control group and treatment group. The control group was treated with interferon and the treatment group was treated with Danggui Beimu Kushen pills on the basis of the control group. The clinical efficacy, incidence of adverse reactions, survival rate, and the relationship with clinical stages were detected in the two groups. The renal function index levels, immune function index levels, and quality of life levels were measured in the two groups after treatment. Results. Compared with the control group, the total clinical effective rate was increased, the abnormal renal function, abnormal liver function, and platelet decline were decreased, and the survival rate was significantly elevated in the treatment group. The patients with clinical stage I∼II’ survival rate was increased, relative to patients with clinical stage III. After treatment, the levels of β2-MG, SCr, BUN, and CD8+ in the two groups were decreased, while the levels of CD3+, CD4+, and CD4+/CD8+ were increased. Moreover, the scores of physical function, social function, emotional function, role function, cognitive function, and total score of the two groups were improved. Compared with the control group, the treatment group changes were more obvious. Conclusion. The Danggui Beimu Kushen Pill has significant clinical effects on the treatment of renal cancer, which can improve the clinical symptoms, enhance the immune function, restore the health renal function, improve the quality of life, prolong the survival time of patients, reduce the incidence of adverse reactions, and provide high safety.
