OBJECTIVETo explore the molecular biology mechanism of acupuncture on improving immune function damage induced by chemotherapy in cancer-bearing mice.

METHODSSeventy-two mice (36 mice in 3-day treatment and 5-day treatment, respectively) which were successfully made into cancer-bearing model were divided into a blank group, a model group, an acupuncture group and a moxibustion group by stratified randomization method, 9 mice in each one. Except for the mice in the blank group, the remaining mice were treated with intra-peritoneal injection of cyclophosphamide (CTX, 150 mg/kg), to establish the cancer-bearing mice of CTX. The mice in the blank group were treated with intraperitoneal injection of 0.9% NaCl (identical dose as other groups). After 4 h, the mice in the acupuncture group and moxibustion group were treated with acupuncture and moxibustion at "Dazhui" (GV 14), "Geshu" (BL 17), "Shenshu" (BL 23), "Zusanli" (ST 36), once a day. The mice in the blank group and model group were treated with immobilization and fixation during the same time. On the next day of the end of 3-day and 5-day treatment, the sample was collected. The ELISA method was applied to measure the contents of IL-12 and TNF-α in spleen of all the mice.

RESULTSAfter 3-day and 5-day treatment, compared with the blank group, the contents of IL-12 and TNF-α in spleen in the model group were reduced (all P < 0.05); compared with the model group, the contents of IL-12 and TNF-α in spleen in the acupuncture group and moxibustion group were increased (all P < 0.05), but the content of IL-12 and TNF-α in the acupuncture group was not different from that in the moxibustion group (both P > 0.05).

CONCLUSIONAcupuncture and moxibustion could effectively increase the contents of IL-12 and TNF-α in spleen of CTX cancer-bearing mice, which could relieve chemotherapy-induced immune function damage to improve immune function.
