Objective To investigate the expression change of P2X3 receptor in spinal dorsal horn and dorsal root ganglion(DRG) in rats with experimental inflammatory pain.Methods Totally 30 SD rats received a subcutaneous injection of carrageenan in the right paw to establish inflammatory pain model,and then divided randomly and equally into 5 groups,that is 6,12,24,72 and 168 h after injection.Another 6 rats undergoing a subcutaneous injection of normal saline in the right paw served as control.Pain threshold was assayed by thermal radiation and von Frey filament in 2,4,6,12,24,72 and 168 h after injection.Expression of P2X3 receptor in spinal dorsal horn and DRG of every group was measured by immunohistochemical staining(IHC).Results After injection of carrageenan,thermal hyperalgesia and mechanical allodynia appeared in the rats.The thermal withdrawl latency(TWL) and 50% paw withdrawl threshold(PWT) were decreased obviously from 2 h,descended to the lowest at 12 h,then returned to the normal level after 72 h.The expression of P2X3 receptor in spinal dorsal horn was increased obviously from 24 h,while that at DRG was increased obviously from 12 h.Both of the expressions lasted for 72 h,and returned to the normal level at 168 h after injection.Conclusion Thermal hyperalgesia and mechanical allodynia appear in the rats after carrageenan injection,and the P2X3 receptor is activated and up-regulated in the DRG and spinal cord,suggesting that P2X3 receptor may play an important role in the incidence and development of inflammatory pain.

In order to improve teaching lever and explore teaching approach, the feasibility study on the combination of the problembased learning method CPBL) and the lecture-based learning method (LBL) was conducted in the teaching of Acupuncture and Moxibustion. The 2010 undergraduates in the major of clinical integrated Chinese and western medicine of five years were randomized into a PBL and LBL group and a LEL group. In the first semester, according to the basic teaching requirement, LBL was used to accomplish the teaching of basic theory. In the internship teaching section, the different teaching method was applied. In the PBL and LEL group, PEL was used, and in the LBL group, LBL was given. At the end of semester, the examination results of the theory learning and medical cases learning were evaluated. The questionnaire was summarized in the teachers and students. The final examination result of theory learning was not different significantly between the two groups (P >0. 05), but the result of medical cases learning in the PEL and LEL group was better than that in LEL group (84. 47±10. 72 vs 76. 00±9. 97, P<0. 05). The questionnaire for the students and teachers indicated that the result of PEL and LEL combined method was higher than that of LEL method (86. 27±8. 36 vs 56. 00±14. 59, P< 0. 01; 45. 89±3. 68 vs 36. 61±6. 41, P<0. 0l), indicating that the combined method of PBL and LEL is feasible in teaching of Acupuncture and Moxibustion and the teaching outcome is superior to the simple LBL, which provides the new approach to the teaching reform.
