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

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.
