摘　　要：OBJECTIVE:To observe the influence of different moxibustion durations on hypothalamic pro-opiomelanocortin(POMC)and prodynorphin(PDYN)mRNA expressions and plasmaβ-endorphin(β-EP)content in rheumatoid arthritis(RA)rats,to understand the mechanism of moxibustion analgesia and its dose-effect relationship.METHODS:Twelve male Wistar rats were randomly selected from 48 male Wistar rats as a normal control group.The RA model was created by raising rats in a windy(blowing with electric fan),cold(6℃±2℃),and wet(80%-90%humidity)environment for 20 days,12 h each day.This was followed byinjectionofFreund'scompleteadjuvant(0.15 mL)into the ankle.Then,rats were randomly divided into a model group,moxibustion groupⅠ,and moxibustion groupⅡ,with 12 rats in each group.In moxibustion groupsⅠandⅡ,moxibustion was given at Shenshu(BL 23)and Zusanli(ST 36)for 20and 40 min,respectively,once daily for 15 days.Hypothalamic POMC and PDYN mRNA expression levels and plasmaβ-EP content were determined.RESULTS:Compared with the normal group,the pressure pain threshold decreased,while the hypothalamic POMC and PDYN mRNA expression levels and plasmaβ-EP content increased in the moxibustion groups(P<0.01).Compared with the model group,the pressure pain threshold,hypothalamic POMC and PDYN mRNA expression levels and plasmaβ-EP content in the moxibustion groups increased significantly(P<0.01).Compared the moxibustion groupⅠ,the pain threshold,hypothalamic POMC and PDYN mRNA expression levels and plasmaβ-EP content in moxibustion groupⅡsignificantly increased(P<0.01).CONCLUSION:Moxibustion has an analgesic effect and increases hypothalamic POMC and PDYN mRNA expression levels and plasmaβ-EP content inRArats.TheanalgesiceffectinmoxibustiongroupⅡisbetterthanthatinmoxibustiongroupⅠ.OBJECTIVE： To observe the influence of different moxibustion durations on hypothalamic pro-opi- omelanocortin（POMC） and prodynorphin（PDYN） mRNA expressions and plasma β-endorphin（β-EP） content in rheumatoid arthritis（RA） rats, to under- stand the mechanism of moxibustion analgesia and its dose-effect relationship. METHODS： Twelve male Wistar rats were randomly selected from 48 male Wistar rats as a normal con- trol group. The RA model was created by raising rats in a windy（blowing with electric fan）, cold（6 ℃ ±2 ℃）, and wet（80%-90% humidity） environ- ment for 20 days, 12 h each day. This was followed byinjectionofFreund＇scompleteadjuvant（0.15 mL） into the ankle. Then, rats were randomly divided in- to a model group, moxibustion group Ⅰ, and moxi- bustion group Ⅱ, with 12 rats in each group. In moxibustion groups Ⅰ and Ⅱ, moxibustion was given at Shenshu（BL 23） and Zusanli（ST 36） for 20 and 40 min, respectively, once daily for 15 days. Hy- pothalamic POMC and PDYN mRNA expression lev- els and plasma β-EP content were determined.RESULTS： Compared with the normal group, the pressure pain threshold decreased, while the hypo- thalamic POMC and PDYN mRNA expression levels and plasma β-EP content increased in the moxibus- tion groups（P0.01）. Compared with the model group, the pressure pain threshold, hypothalamic POMC and PDYN mRNA expression levels and plas- ma β-EP content in the moxibustion groups in- creased significantly（P0.01）. Compared the moxi- bustion groupⅠ, the pain threshold, hypothalamic POMC and PDYN mRNA expression levels and plas- ma β-EP content in moxibustion groupⅡsignifi- cantly increased（P0.01）. CONCLUSION： Moxibustion has an analgesic effect and increases hypothalamic POMC and PDYN mRNA expression levels and plasma β-EP content inRArats.Theanalgesiceffectinmoxibustiongroup ⅡisbetterthanthatinmoxibustiongroupⅠ.
