Abstract:Objective: To explore the effect of Dr. Lu breathing exercise training on serum IGF-1, IL-6 levels and the exercise tolerance(the results of 6-minute walk test) in patients with lung cancer after operation. Methods: 180 patients with lung cancer were divided into experimental group and control group according to the order of admission time. The control group received routine nursing, and the experimental group received routine nursing combined with Dr. Lu postoperative respiratory exercise training for 90 days. The serum levels of IGF-1 and IL-6 and the results of 6-minute walk test between the two groups were evaluated. Results: The levels of serum IGF-1 and IL-6 in the experimental group were significantly lower than those in the control group (P < 0.05). The 6-minute walking distance of the experimental group was significantly longer than that of the control group on the 90th day after surgery (P < 0.05). At the same time, the dyspnea score of the experimental group did not increase compared with the control group. Conclusion: Dr. Lu respiratory exercise training can reduce the serum IGF-1 and IL-6 levels of patients with lung cancer after operation, and improve the exercise tolerance of patients with lung cancer after operation.
