Abstract:
Objective To observe the effect of Jianpi Buxue Decoction on the protein expression of neurokinin 1 receptor (NK1R) and CD34 in C57BL/6 mice of lung cancer after chemotherapy, and to explore the improvement of chemotherapy-induced nausea and vomiting and myelosuppression treated with Jianpi Buxue Decoction. Methods Forty C57BL/6 mice were transplanted with Lewis lung cancer cells in the armpit of left anterior limb after being fed for 7 days, and then were randomly divided into lung cancer group, model group, and high-, middle- and low-dose Chinese medicine groups. Model group and Chinese medicine groups were injected intraperitoneally with cyclophosphamide (80 mg/kg) for one day. Lung cancer group and model group were given normal saline. Chinese medicine groups were administered with high-, middle- and low-dose of Jianpi Buxue Decoction (25, 12.6, 6.25 g/kg respectively) for 14 days. After the modeling, all of the mice were sacrificed, and then the brains and spleens were sampled. Western blotting method was used to detect the protein expression of NK1R and CD34. Results Compared with lung cancer group, the protein expression of cerebral NK1R and splenic CD34 in the model group was increased significantly ( P<0.01) . Compared with the model group, the protein expression of NK1R in mice brain tissues of high-, middle- and low- dose Jianpi Buxue Decoction groups was decreased significantly (P<0.01) , while the protein expression of CD34 in spleen tissues of middle-and low-dose Jiangpi Buxue Decoction groups was increased obviously ( P<0.05) . Conclusion Jianpi Buxue Decoction has an effect on down-regulating the protein expression of NK1R in brain tissues and on up-regulating the protein expression of CD34 in spleen tissues of C57BL/6 mice with lung cancer after chemotherapy, indicating that Jianpi Buxue Decoction probably can relieve chemotherapy-induced nausea and vomiting, and can improve the myelosuppression after chemotherapy.
