Objecitve To observe the effects of ursolicacid on contractile activity of uterine smooth muscle strips of virginal rats.Methods 20 Wistar virginal rats,weight 200-300g were selected,to record the effects of ursolicacid(1.0?10~(-8),2.0?10~(-8),3.0?10~(-8),4.0?10~(-8)g/L) on contractile activity of uterine smooth muscle strips with Biolap 410 Biological System.Diphenhydramine(2?10~(-6)mol/L),Phentolamine(2?10~(-6)mol/L),Verapamil(2?10~(-7)mol/L),Indomethacin(2?10~(-5)mol/L) were used as antagonists to study the mechanisms of ursolicacid on uterine smooth muscle strips.Results Ursolicacid could significantly potentiate uterine contractile activity of virginal rats.It could increase the frequencies,prolong the duration and enlarge the amplitude of contractile activity.The effect of which could be inhibited by the Indomethacin;but could not restrained by other antagonists.Conclusion The results of Ursolicacid may be mainly primarily with prostaglandin synthese or release,but not mediated by H_(1) receptor,? receptor and L-voltage-dependant calcium channels.

Objective To clarify whether the mRNA expression level of glucocorticoid receptor (GR) in the peripheral blood mononuclear cells (PBMCs) can predict the clinical response to glucocorticoid (GC) in patients with pemphigus. Methods Reverse-transcription polymerase chain reaction (RT-PCR) was applied to determine the mRNA expression of GR? and GR? in PBMCs from 30 patients with pemphigus and 30 healthy volunteers. Results GR? mRNA was detected in all patients and all healthy volunteers, and the expression of GR? mRNA in pemphigus patients was significantly lower than that in healthy volunteers (P = 0.044), but no significant difference was found between patients insensitive and sensitive to glucocorticoid. In contrast, GR? mRNA was detected in 10 of 12 patients insensitive to glucocorticoid, 3 of 18 patients sensitive to glucocorticoid, and 9 of 30 healthy Volunteers. The positive rate of GR? in the insensitive group was significantly higher than that in the sensitive group (P

Objective:To investigate the synergistic effect and mechanism of the combined application of recombinant human bone morphogenetic protein-2(rhBMP-2) and basic fibroblast growth factor (bFGF).Methods:24KM male mice were randomly divided into6 groups with4 mice in each group, namely,GroupA(control group),GroupB(only treated with collagen),GroupC(treated with 2 ng bFGF+collagen),GroupD(treated with4 μg rhBMP-2+collagen),GroupE(treated with4 μg rhBMP-2+2 ng bFGF+collagen) andGroupF(treated with4 μg rhBMP-2+4 ng bFGF+collagen). The composites were implanted into the intermuscular septum of hind legs mice; whereas in control group, intermuscular septum of mice was separated and no implantation was performed. General observation, detection of concentration of calcium content, micro computed tomography (Micro-CT), three-dimensional reconstruction scan, measurement of bone mineral density(BMD), bone volume fraction(BVF) and trabecular thickness(Tb.Th), as well as histological observation withHE staining andALP andCD34 immumohistochemical staining were performed.Results:Ectopic osteogenesis was found inGroupsD,E andF mice.The difference in concentration of calcium contentswas statistically significant betweenGroupsD andE(P<0.05), but insignificant betweenGroupsE andF(P>0.05).Micro-CT and three-dimensional reconstruction revealed continuous newborn bone substance in external surface of ectopic bone formation, and the center of bone formation did not show obvious substantial filling by bone substance.The differences in BMD,BVF andTb.Th were statistically significant betweenGroupsD andE orF(P<0.01 or <0.05). HE staining showed that inGroupsD,E andF, newborn bone substance was mainly located at the edge of ectopic bone formation, and the bone formation inGroupsE andF was better than that in GroupD.ALP andCD34 immumohistochemical staining revealed the positive expression mainly at the edge of ectopic bone formation, and area of positiveexpression inGroupsE andF was larger than that inGroupsD.Conclusions:rhBMP-2 possesses the capacity to induce ectopic osteogenesis independently, but bFGF does not have this ability; the combined application of rhBMP-2 and bFGF can enhance the synergetic effect on inducing ectopic osteogenesis.
