China Journal of Chinese Materia Medica 2014;39(3):520-525
This study aim to reveal the total pharmacokinetics of rhein and chrysophanol after oral administration of Quyu Qingre granules (QUQRG) in normal and acute blood stasis rabbits, to identify the pharmacokinetics differences between two groups of rabbits and to evaluate the applicability of the total statistical moment analysis. Based on the concentrations of rhein and chrysophanol in plasma determined by an established HPLC method, and the calculation of main total pharmacokinetic parameters, this study found that total pharmacokinetic parameters VRT, value of blood stasis group is lager than that of normal group and the difference is significant Compared with normal group, total pharmacokinetic parameters AUC,, MRT,, t1/2t, and Vt value of blood stasis group is lager, while the k, and CL, value is smaller. The findings indicated that the absorbed and released time of rhein and chrysophanol was accelerated and the total absorptive amount of these two compounds was increased in rabbits with acute blood stasis, compared with the normal rabbits. Total quantity statistical moment analysis can combine the pharmacokinetics of rhein and chrysophanol and express the pharmacokinetic behavior of these two compounds in QUQRG. The parameters in this paper can provide reference frames for the follow-up development of QUQRG.

OBJECTIVETo investigate the expressions of GRα, GRβ, GRγ, GRp and heat shock protein 90 (HSP90) in primary immune thrombocytopenia (ITP) patients and their correlations with glucocorticoid resistance.
METHODSThe expressions of glucocorticoid receptors (GRα, GRβ, GRγ, GRp) mRNA and HSP90 in peripheral blood mononuclear cells of 40 newly diagnosed ITP patients and 29 healthy volunteers were examined by real time PCR. Of them, 28 patients received glucocorticoid (GC) therapy divided into GC sensitive group (GCS) and GC resistant group (GCR) according to GC response. GRα, GRβ, GRγ, GRp, HSP90 mRNA and HSP90/GRα were analyzed in paired groups.
RESULTSThe expression of HSP90 mRNA was significantly decreased in ITP patients \[0.91(0.48 - 2.21)\] than in normal subjects \[1.41(0.83 - 2.61)\] (P < 0.05). There were no significant differences in mRNA expressions of GRα, GRβ, GRγ, GRp and HSP90/GRα between ITP patients and normal controls. The expression of GRα mRNA in GCS patients was significant higher than in GCR patients (P < 0.05). Moreover, no significant differences in mRNA expressions of GRβ, GRγ, GRp and HSP90 and the ratio of HSP90 to GRα were observed between GCS and GCR patients.
CONCLUSIONThe expression of HSP90 mRNA decreased in adult ITP patients. GC resistance in adult ITP patients was associated with reduced expression of GRα. The very low expression of GRβ mRNA may be not involved in GC resistance in adult ITP.

To investigate the mechanism of agarwood formation in Aquilaria sinensis induced by Lasiodiplodia theobromae, the fermentation liquor of L. theobromae was analyzed qualitatively and quantitatively by gas chromatography-mass spectrometry (GC-MS). JAs were detected in the fermentation liquor. The effect of the fermentation liquor on the abundance of sesquiterpenes in the callus of A. sinensis was analyzed by solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS). And the fermentation liquor stimulated alpha-guaiene, alpha-humulene and delta-guaiene biosynthesis in calli. It was inferred that L. theobromae produced JAs, which resulted in a significant increase of sesquiterpenes in A. sinensis.
