Objective To investigate the effect of cordyceps sinensis from different origins on immune response in mice. Methods Cordyceps sinensis from two origins were prepared into powder, and then the mice were divided into high, middle and low dose(0.4,0.2,0.1 g.kg-1)groups, respectively.In addition, purified water was given as the normal control group.Effects of cordyceps from two different origins were observed by detecting spleen lymphocyte proliferation induced by ConA, delayed type hypersensitivity ( DTH) in mice induced by sheep red blood cells ( SRBC ) , the number of antibody-producing cells, carbon clearance and peritoneal macrophages Swallow fluorescent microspheres, as well as the activity of NK cells. Results The ability of spleen lymphocyte proliferation induced by ConA, carbon clearance and peritoneal macrophages Swallow fluorescent microspheres, and the activity of NK cells were significantly enhanced in the middle and high dose group of two different origins cordyceps, compared with normal control group (P<0.05).Additionally, the number of antibody-producing cells was obviously increased in medium dose group of both origins cordyceps and decreased in the high dose group (P<0.05).The middle and high dose Qinghai cordyceps significantly improved DTH in mice, while Tibet cordyceps sinensis had no obvious effect, and there was significant difference (P<0.05) between the high dose group of Qinghai and three dose groups of Tibet Cordyceps sinensis.In addition, levels of serum hemolysin in mice were significantly increased in the middle and high dose group of Qinghai and high dose group of Tibet Cordyceps sinensis (P<0.05), and the differences of corresponding medium and high doses of two origins were significant ( P<0.05) . Conclusion Cordyceps sinensis of both different regions significantly improved the immune response of mice.However, the efficacy between the two origins was roughly equivalent and had no significant difference.

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 evaluate the relationship between interleukin-18(IL-18) and insulin resistance, measured by euglycemic hyperinsulinemic clamp, in women with polycystic ovary syndrome (PCOS). Methods Forty-two young women with PCOS and 38 age-and body mass index (BMI)- matched control women were recruited in this study. A complete hormonal assay was performed and serum IL-18 level was determined in each subject. And euglycemic hyperinsulinemic clamp test was completed in 41 of the above subjects. Results Serum IL-18 levels were increased in the PCOS women, as compared with the control (P=0.033). When all subjects were divided into lean and obese groups, the IL-18 levels were slightly increased in the obese subjects (P=0.902). IL-18 levels were negatively correlated with all the clamp parameters [mean glucose infusion rate (M), M-to-insulin ratio (M/I) and glucose metabolic clearance rate (MCRg), r =-0.419,-0.396,and-0.405,P=0.006,0.010 and 0.009 respectively], but were positively associated with HOMA-β index(r=0.334, P=O.035). Conclusion Serum IL-18 level was significantly increased in PCOS women and was strongly associated with the parameters obtained from the euglycemic hyperinsulinemic clamp, indicating that IL-18 may be an important mediator between inflammation and insulin resistance.

The aim of the manuscript was to optimize formulations and preparation technologies of cataplasm of white mustard seed varnish, and to evaluate its anti-asthma effect on rats. The single factor experiments included spreading thickness, types of crosslinking agents, dihydroxyaluminum aminoacetate amount, sodium polyacrylate amount, types of adhesive agents with human sense as the evaluation index. Blank cataplasm matrix was optimized by the orthogonal experiment with the amount of glycerine, citric acid, and sodium carboxymethylcellulose as the major influential factors. Initial adhesive force, peeling strength and human sense were as the evaluation index. The optimized formulation of blank cataplasm were as followings: glycerine-water-ethanol-PEG400-dihydroxyaluminum aminoacetate-citric acid-sodium carboxymethylcellulose-sodium carboxymethylcellulose 2 : 8 : 0.8 : 0.4 : 0.07: 0.15 : 0.1 : 0.5. The active ingredients of white mustard seed, corydalis, and gansui root were extracted by alcohol extraction method. Asiasarum volatile oil was extracted by oil extractor. The optimized drug loading amount was 11% with initial adhesive force, peeling strength and human sense as the evaluation index. Asthma rats model were established by sensitized with ovalbumin and nose-scratching time as the evaluation index. High dose (17%) group of drug-loaded cataplasm had the obvious inhibition effect on nose-scratching time of rats (P = 0.037 < 0.05). In comparison, middle dose (11%), low dose (4%) and positive-control groups had no obvious inhibitive effect on rats. White mustard seed cataplasm supplied a novel choice for anti-asthma therapy. And the overall pharmacodynamics assessment will be carried out on molecular level in near future.
