Objective To discuss the role of therapeutic drug monitoring (TDM) in pharmaceutical care by successful intervention of severe drug-drug interaction in 3 patients with hematological disease treated with voriconazole and rifampin.Methods Three patients with hematological disease were monitored for the plasma concentration of voriconazole before,during,and after the concomitant use of rifampin.The severity of this drug interaction was revealed,risks for developing invasive fungal infection and tuberculosis dissemination after chemotherapy were evaluated based on the TDM results,and alternative regimens were recommended.Results Voriconazole plasma concentration was normal at baseline but significantly depressed after combination with rifampin in all 3 cases.Concomnitant use of rifampin leads to a rapid decline in plasma concentration of voriconazole in 2-3 days,and withdraw of this enzyme induction effect takes 8-10 days after discontinuation of rifampin.Conclusion TDM is a helpful tool for providing pharmaceutical care,it helps to objectively visualize the degree of clinically important drug-drug interactions.Clinical evidence together with TDM results suggests high risk for developing invasive fungal infection and tuberculosis dissemination in hematology patients while using this combination therapy.Discontinuation of rifampin was suggested and accepted.For these patients,combination of voriconazole and rifampin should be avoided.

Objective: To study the chemical constituents in the aerial parts of Tetracera asiatica. Methods: Silica gel, ODS, Sephadex LH-20 gel column chromatographies, and HPLC were used to isolate and purify the compounds.

Objective To observe the changes of bone mass in reloaded rats after tail-suspension,and the effect and mechanism of simvastatin on this process.Methods Twenty-four 5-month old rats were divided into 4 groups of 6 animals in each group: Control (CL) group without tail-suspension,unloaded (UL) group with tail-suspension for 6 weeks,other 12 rats received tail-suspension for 3 weeks,then reloaded for subsequent 3 weeks (UL+RL) or combined with simvastatin treatment (UL+RL+SIM) at a dose of 10 mg/kg/d.All rats were sacrificed 6 weeks later,and the left femur was used for examination of bone mineral density,left tibia was used for bone histomorphometry analysis,the right femur and tibia were harvested for biomechanical test,and expression levels of type I collagen by real-time PCR and Western blot,respectively.Results 1.BMD of the CL group was significantly higher than those of the other three groups (P<0.05),and was markedly lower than those in the UL+RL and UL+RL+SIM groups (P<0.05).2.The bone histomorphometry showed that BV/TV in the CL group was significantly higher than those in the other 3 groups,and the UL+RL and UL+RL+SIM groups showed a significantly higher BV/TV than that of UL group (P<0.05).The Tb.Th was significantly higher in the CL group than in the UL group.The Tb.Sp in the CL group was significantly lower than those in the other 3 groups (P<0.05).The UL+RL and UL+RL+SIM groups showed significantly lower Tb.Sp than that of the UL group (P<0.05).3.Biomechanical test showed that the maximal load and elastic modulus in the CL groups were significantly higher than those of the other three groups (P<0.05).4.Real-time PCR showed that no significant difference in the mRNA expression level of Col I was found between any two groups.5.Western blot showed that the IOD of Col I is significantly lower than that in the CL group.Conslusions Bone loss,destruction of trabecular bone micro-architecture and biomechanical properties and reduction of type 1 collagen are present in tail-suspension treated rats,which are partially restored after reloading,and this recovery process is not enhanced by simvastatin treatment.

The traditional Chinese medicine (Tripterygium wilfordiiHook.f.,TWH) has been clinically used to treat primary and secondary renal diseases and proteinuria for nearly 40 years.However,there is a rare literature about the effect of triptolide (the main active ingredient of TWH) on the expression of oxidative carbonyl protein (OCP) in diabetic nephropathy (DN).This study aimed to provide experimental evidence for triptolide treatment on DN through its effect on the expression of OCP,in order to investigate the effects of triptolide on the expression of OCP in rats with DN.Sixty SD rats were randomly divided into five groups:control group,high-dose triptolide (Th) group,low-dose triptolide (T1) group,DN model group,and positive control (benazepril) group.The DN model was established using streptozotocin.Urinary protein excretion,fasting blood glucose (FBG),superoxide dismutase (SOD) in renal homogenate,malondialdehyde (MDA) in renal homogenate and renal nitrotyrosine by immunohistochemistry,and the expression of OCP by oxyblotimmune blotting were detected.In the DN model group,rat urinary protein excretion and renal MDA were significantly increased,while renal SOD significantly decreased and nitrotyrosine expression was obviously upregulated in the kidney.After triptolide treatment,24-h urinary protein excretion (61.96±19.00 vs.18.32±4.78 mg/day,P＜0.001),renal MDA (8.09±0.79 vs.5.45±0.68 nmol/L,P＜0.001),and nitrotyrosine expression were decreased.Furthermore,renal OCP significantly decreased,while renal SOD (82.50±19.10 vs.124.00±20.52 U/L,P＜0.001) was elevated.This study revealed that triptolide can down-regulate the expression of OCP in the renal cortex of DN rats.
