Résumé
Long terms of chronic pain may induce emotional disorder such as depression,anxiety and aversion.It is worthy of studying the mechanism and therapy on pain emotional disorder.The animal model is important in basic researches,and the quantitative evaluation methods on the psychiatric factors are gradually applied in the pain research.The methods of evaluating the psychiatric disorder of pain are discussed in this paper,which will provide theory basis in the relevant fields.

Objective] To observe the influence of YIGU oral liquid on the pain threshold and bone mineral density in ovariectomized rats. [Methods] Eighty-four Female SD rats were randomly divided into 4groups:YIGU oral liquid group, calcitonin group,YIGU oral liquid combined with calcitonin group, saline control group.The ovariectomized rats were confirmed the successful model of osteoporosis,rats in the YIGU oral liquid group were administered with YIGU oral liquid, rats in the calcitonin group were administered with calcitonin, rats in the YIGU oral liquid combined with calcitonin group were administered with YIGU oral liquid group and calcitonin,rats in the saline control group were administered with saline.To detect the pain threshold and bone mineral density at the 10th day, 30th day, 60th day and 90th day respectively. [Results]At the 10th, 30th, 60th and 90th day after treatment, the pain threshold of the YIGU oral liquid group, calcitonin group,YIGU oral liquid combined with calcitonin group compare to saline control group, there was significant statistical difference( P0.05). At the 60th,90th day after treatment, there was significant statistical difference( P<0.05).[Conclusion] YIGU oral liquid can effectively enhance pain thresh-old and bone mineral density of the ovariectomized rats to inhibit the osteoporosis pain.

[Objective]To observe the influence of Yigu oral liquid on inhibiting the pain in ovariectomized rats by detecing the pain threshold, bone densi-ty, serum inflammatory factor, vascular endothelial function(ET) and platelet activating capacity(CD62p and CD63).[Method]80 SD rats were randomly di-vided into four groups of sham group, Yigu oral liquid group, Miacalcic group,control group. There were 20 in each group.Yigu oral liquid group,Mia-calcic group,control group were ovariectomized,sham group underwent sham operation. After confirming the successful model of osteoporosis, sham group was administrated with saline, Miacalcic saline group was administrated with Miacalcic by intramuscular injection ,Yigu oral liquid group was administrated with Yigu oral liquid ,saline and control group was administrated with saline.The indicators of pain threshold,bone density,vascular endothelial function (ET) and platelet activating capacity(CD62p and CD63), serum inflammatory factors as COX-2, PGE2, cAMP were respectively detected. [Results] The levels of peripheral inflammatory factors as COX-2, PGE2, cAMP , vascular endothelial function(ET) and platelet activating capacity(CD62p and CD63)of Yigu oral liquid group decreased significantly compared with the control group( P<0.05). The level of pain threshold and bone density of Yigu oral liquid group improved significantly compared with the control group(P<0.05).[Conclusion]Yigu oral liquid can inhibit osteoporosis pain by improving the level of pain threshold ,bone density,and decreasing the levels of COX-2, PGE2, cAMP, vascular endothelial function(ET) and platelet activating capacity (CD62p and CD63).

[Objective]To investigate the effects of YIGUTANG contaning serum on osteoblasts proliferation which was from the skull of newborn SD rat in vitro.[Methods] The osteoblast from newborn SD rats’skull adopted, take the method of collagenase-pancreatic enzyme digestion,then respectively culture these osteoblasts with different concentration of the YIGUTANG drug containing serum fluid together.[Results]YIGUTANG drug containing serum could stimulate the proliferation of osteoblast, and the high,the middle and the low concentrations groups contrasted with the control group, all could promote the proliferation of cell .The drug containing serum groups had insignificant difference from the blank control group(P
