Objective:To study how to guide the individual dose of clopidogrel in line with the genetic testing results. Methods:Clinical pharmacists decided how to optimize the prescription of clopidogrel according to the genotype combined with the drug metabolism and drug interactions for three patients respectively with slow clopidogrel metabolism,intermediary metabolism and super fast metabolism. Results:The slow clopidogrel metabolism patient with subacute stent thrombosis after half a month of coronary stenting was switched to orally administrate with ticagrelor. The super fast metabolism patient suffered from repeatedly subcutaneous hemorrhage with antiplatelet therapy was suggested to lower the dose of clopidogrel,temporarily withdraw Maixuekang capsules and conventionally administrate with vitamin C tablets orally. The intermediary metabolism patient with late stent thrombosis co-treated with lansoprazole was suggested to increase the dose of clopidogrel or use ticagrelor instead,and when it was necessary,panxitorazole,ray Bella or the other ranitidine acid suppression drugs such as ranitidine could be considered. Conclusion:Through genetic testing and drug interactions,clinical pharmacists guide the clinical use of clopidogrel and the optimization of antiplatelet therapy.

Over-expression of P-glycoprotein (Pgp) is associated with the development of multi-drug resistance ( MDR). Pgp has been focused on as the main target in designing chemotherapy strategy. In this article we review some of the latest advancement in designing and evaluation methods of P- glycoprotein inhibitors.

Objective To explore the mechanism through which nicotine protects dopaminergic neurons against 6-OHDA toxicity in SD rat. Methods Rats received nicotine or saline treatment (two doses tested,0. 2 rag/ kg and 2 rag/ kg, 5 injections i.p. per day at 2-h intervals). On day 8after the treatment, a single injection of 20μg of 6-OHDA was administered into right striatum.Nicotine or saline was administered continuously daily until animals were killed. The dopaminergic neurons and CD3, CD4 and CDS-positive lymphocytes were analyzed quantitatively using immunohistochemistry. Microglia activation was quantified by IBA1 immunofluorescence. Results The loss of dopaminergic neurons induced by 6-OHDA in the substantia nigra was significantly less severe in the nicotine treatment group (at both 0. 2 and 2 mg/kg groups) than that in the saline treated group. In the striatum, we observed that the number of CD3, CD4 and CD8-positive lymphocytes reduced significantly in the nicotine treated animals as compared to saline controls. Otherwise, nicotine inhibited CD4 and CD8-positive lymphocytes infiltration equivalently. Quantitative immunofluorescenee analysis indicated the microglia activation was inhibited obviously in nicotine treatment. Conclusions Our data suggest that nicotine may have a neuroprotective effect against dopaminergic lesion induced by 6-OHDA by inhibiting the inflammation.

Objective To study the effect of total nutrient admixture (TNA) on lipid metabolism in rats with acute hepatic failure (AHF). Methods Fifty-six male Wistar rats were randomly divided into four groups: normal diet group, nitrogen-free diet group, fat-free nutrient admixture group, and TNA group. All rats were injected with D-galac- tosamine to induce AHF model Meanwhile, 6 healthy Wistar rats were used as control group. TNA provided energy 221.75 kJ (1 kcal=4.184 kJ), nitrogen 0.365 g, nitrogen to energy ratio 1:145, amino acids 2.28 g (including branched-chain amino acid 0.70 g), glucose 7.85 g, and fat 1.25 g on a daily basis. After 10 days of the operation of Jugular vein puncture tube, blood glucose, blood lipid, liver and renal function were determined. Results The blood glucose level was significantly higher in TNA group than that in fat-free nutrient admixture group (P < 0.05). The levels of serum triglyceride and cholesterol were highest in fat-free nutrition admixture group, and triglyceride level was signif- icantly higher than that in normal diet group and nitrogen-free diet group (P <0.05). The levels of serum triglyceride and cholesterol were significantly higher in TNA group than those in normal diet group (P <0.05). The levels of ala- nine aminotransferase, alkaline phosphatase, total bilirubin and blood urea nitrogen were lower in TNA group than those in fat-free nutrient admixture group (P < 0.05). Conclusion The nutritional proportion of TNA is suitable for the metabolism disorder of hepatic failure, and therefore TNA can reasonably promote the anabolism and reverse the deteri- oration of hepatic failure in rats.

Objective To develop a method for the simultaneous separation and determination of 10 kinds of sedative hypnotica drugs in the functional food with high performance liquid chromatography mass spectrometry system.Methods The mobile phase consisted of acetonitrile and 15 mmol/L ammonium acetate solution(0.1% formic acid ),chromatographic column was Zobax SB C 18.Identification was based on the compound's absolute retention time,protonated molecular ion,and representative fragment ion by multiple reaction monitoring.The condition of determination was investigated and optimized.Results With this method,the linear range for the 10 drugs was 10-1 080 ?g/kg,the average recoveries ranged from 80.5%-97.1% and the detection limits were from 0.35-12.0?g/kg respectively.Conclusion The method established in the present paper is applicable to monitoring sedative hypnotica drug in the functional food.

Objective:To evaluate the clinical efficacy between preparation porcelain veneer(PPV)and no-preparation porcelain veneer(NPPV).Methods:44 patients with 97 PPVs and 23 patients with 57 NPPVs were followed up for 3 years.Mental tension, postoperative dentin sensitivity and satisfaction of the patients,survival rate of the veneers,sulcus bleeding index(SBI)of preopera-tive and postoperative 3 years were evaluated.A comparative analysis was taken to examine the clinical indicators of 2 groups accord-ing to the modified CDA /Ryge criteria.Results:Survival rates of PPVs and NPPVs were 96.91 % and 96.49%(P >0.05),satisfac-tion rates of the 2 group patients were 95.45% and 95.65%(P >0.05),respectively.Mental tension and the postoperative dentin sensitivity of patients in PPV group was higher than those in NPPV group.Preoperative and postoperative SBI were not statistically dif-ferent between the 2 groups(P >0.05).Marginal adaptation in PPV group was better than that in NPPV group.Color matching, Porcelain surface and Marginal stain were not statistically different between 2 groups.Conclusion:Preparation porcelain veneers and no-preparation porcelain veneers both are effective in clinical application.
