Abstract: Objective:  To explore the effects of three-acupoint and five-needling method on Eotaxin and RANTES expressions in lung tissues of asthmatic rats. Methods:  Thirty SPF male SD rats were randomly divided into blank  group,  model  group  and  acupuncture  group  with  10  rats  in  each  group  with  corresponding interventions. Physiological recorder was used to record airway resistance and pulmonary compliance, HE staining was applied to observe the morphologic changes of lung tissues, the immunohistochemical method was applied to test the expression of Eotaxin and RANTES in lung tissues. Results: Compared with the blank group, the airway resistance was higher in the model group(P<0.05),compared with the model group, the acupuncture  group  reduced  (P < 0.05).  Compared  with  the  blank  group,  the  pulmonary  compliance reduced in the model group (P<0.05), compared with the model group, the acupuncture group improved(P<0.05). HE staining of rat lung indicated that the pathological changes of acupuncture group was obvious, inflammatory reaction was reduced after acupuncture. Compared with  the blank group, the expression of Eotaxin  and  RANTES  in  lung  tissues  of  model  group  was  higher (P<0.05),  the  acupuncture  group  was reduced(P<0.05).  Conclusion:  Three-acupoint and five-needling method could reduce Eotaxin and RANTES expressions in lung tissues of asthmatic rats, thus reducing airway inflammatory reaction.
