The inter-species differences of thienorphine metabolism were investigated in human, Beagle dog and rat liver microsomes, by comparing enzyme kinetics of the parent drug and the formation of its major metabolites. The incubation systems of thienorphine with liver microsomes of the three species were optimized in terms of thienorphine concentration, microsomal protein content and incubation time. The concentrations of thienorphine and its metabolites in incubates were measured by a LC-MS/MS method. The biotransformation of thienorphine by human liver microsomes was the lowest among the three species. The K(m), V(max), CL(int) and T1/2 of thienorphine obtained from human liver microsomes were (4.00 +/- 0.59) micromol x L(-1), (0.21 +/- 0.06) micromol x L(-1) x min(-1), (117 +/- 3.19) mL x min(-1) x kg(-1) and (223 +/- 6.10) min, respectively. The corresponding kinetic parameters for dog and rat liver microsomes were (3.57 +/- 0.69) and (3.28 +/- 0.50) micromol x L(-1), (0.18 +/- 0.04) and (0.14 +/- 0.04) micromol x L(-1) x min(-1), (213 +/- 1.06) and (527 +/- 7.79) mL x min(-1) x kg(-1), (244 +/- 1.21) and (70.7 +/- 1.05) min, respectively. A total of six phase I metabolites were observed in liver microsomes, including one N-dealkylated metabolite, three oxidative metabolites and two N-dealkylated oxidation metabolites. All these six metabolites were detected in the liver microsomes of the three species. However, the relative amounts of the metabolites generated were different in three species. The results indicated that the major phase I metabolic pathway of thienorphine was similar in the liver microsomes from all three species. However, the inter-species differences observed were relative amounts of the metabolites as well as the metabolic characteristics of thienorphine in liver microsomal incubates.

Objective To investigate the effects and partial mechanism of prednisone and TACI-Ig combination on MRL/Mpslac-lpr ( MRL/lpr) mice. Methods MRL/lpr mice were randomly divided into 6 groups, which includ-ed model group, prednisone (2. 5, 5. 0 mg/kg) group, TACI-Ig (15. 0 mg/kg) group, prednisone and TACI-Ig combination [(2. 5+7. 5) mg/kg, (2. 5+15. 0) mg/kg] group. BALB/c mice were set as normal group. Pred-nisone was given intragastrically everyday and TACI-Ig was given subcutaneously every two days for 13 weeks. In the meantime, the normal and model group were treated with an equal volume of normal saline. The general sign and proteinuria level were observed in the treatment period. The sections of spleen and kidney tissues for pathologi-cal analysis were stained with HE. Serum levels of auto-antibodies and BAFF were detected by ELISA kit. The per-centage of plasma cells and CD138 expression in the spleen were detected by flow cytometry analysis and immuno-histochemistry, respectively. Results The skin damage and the proteinuria level were improved and decreased by prednisone and TACI-Ig combination treatment. The spleen and kidney pathology were also improved including re-ducing germinal center formation and alleviating the glomerular fibrosis, mesangial cell hyperplasia and inflammato-ry cell infiltration, respectively. What was more, the percentage of splenic plasma cells ( CD19 -CD138 +) was re-duced significantly, which maybe resulted in the decrease in ANA. However the high level of anti-dsDNA antibody was not influenced by the combination treatment. The serum level of BAFF was also reduced by the combination treatment. Conclusion Prednisone and TACI-Ig combination treatment has a beneficial effect on murine SLE, which may be associated with the inhibition of plasma cell differentiation and the secretion of auto-antibody.

Objective To observe the curative effect of warm needling therapy combined with kidney-supplementing and blood-activating Chinese herbal medicine on patients with scapulohumeral periarthritis and its effects on immunoglobulin IgA, IgG and IgM;To explore the mechanism. Methods Ninety patients with scapulohumeral periarthritis were randomly divided into needle with medicine group, needle group and medicine group, 30 cases in each group. Patients in the needle with medicine group were treated with needle warming therapy combined with kidney-supplementing and blood-activating Chinese herbal medicine, patients in the needle group were treated with needle warming therapy, patients in the medicine group were treated with kidney-supplementing and blood-activating Chinese herbal medicine, 30 days for medicine and every other day for acupuncture. Five time acupuncture was one course of treatment, and patients were treated for 3 courses. Shoulder pain index was evaluated, and the levels of IgA, IgG and IgM was determined before and after 3 courses treatment. The total curative effect of the three groups were compared. Results The total effective rates for needle and medicine group, needle group and medicine group were 93.33% (28/30), 73.33% (22/30), 66.67% (20/30), respectively, with statistical significance between needle and medicine group and the other two groups (P<0.05),without statistical significance between needle group and medicine group (P>0.05). There was statistical significance between the shoulder indexes before and after treatment of the three groups (P<0.05). Before treatment, the levels of IgA, IgG and IgM of all three groups increased significantly compared with the normal reference values (P<0.05). After treatment, the levels of IgA, IgG and IgM were reduced significantly in three groups after treatment (P<0.05), the levels of IgA, IgG and IgM in the needle and medicine group were significantly lower than those in the other two groups (P<0.05). Conclusion The curative effect of needle warming therapy combined with kidney-supplementing and blood-activating Chinese herbal medicine was better than alone needle warming therapy or kidney-supplementing and blood-activating Chinese herbal medicine. This combined therapy could significantly improve the symptoms of patients, reduce the levels of IgA, IgG and IgM, regulate the body immune function, which is probably one of the mechanisms in the treatment of scapulohumeral periarthritis.
