ABSTRACT
OBJECTIVE@#To compare the accuracy of five warfarin-dosing algorithms and warfarin stable dose model (2.5 mg/day) for Shandong population.@*METHODS@#One hundred and twenty five patients who achieved stable warfarin dose were enrolled. Clinical and genetic data were used to evaluate the value of each algorithm by calculating the percentage of patients whose predicted warfarin dose was within 20% of the actual stable therapeutic dose and mean absolute error (MAE).@*RESULTS@#The frequency of patients with CYP2C9*1/*1, CYP2C9*1/*3 and CYP2C9*1/*2 genotype was 92.00%, 7.20%, 0.80%, respectively. That of VKORC1-1639 AA, AG and GG genotype was 82.40%, 15.20%, 2.40%, respectively. CYP4F2*1/*1, *1/*3, *3/*3 genotype was 50.40%, 39.20%, 10.40%, respectively. With the same genotypes for other loci, patients who carried at least one VKORC1-16398G mutant allele had increased warfarin stable daily dose compared with VKORC1-1639AA. Compared with CYP4F2*1/*1, those carrying at least one CYP4F2*3 mutant allele had warfarin stable daily dose increased by 5.9%-13.00%. The percentage of ideal prediction calculated from IWPC model (59.20%), Huang model (57.60%) and Ohno model (52.80%) were higher than others. The MAE were 0.35 (95%CI: 0.11-0.49), 0.15 (95%CI: 0.10-0.32), 0.39 (95%CI: 0.12-0.51), respectively.@*CONCLUSION@#The polymorphisms of CYP2C9, VKORC1 and CYP4F2 genes can influence the stable dose of warfarin in Shandong population. IWPC algorithm is suitable for guiding the use of warfarin in this population.

ABSTRACT
Objective To evaluate the therapeutic effect of Yin-Huang pills combined with Banlangen granule therapy on upper respiratory infection.Methods 120 cases of acute upper respiratory infection were randomly separated into an experiment group and a control group.The experiment group was treated by Yin-Huang pills combined with Banlangen granule;while the control group was treated by Yin-Huang pills.Results There was significant difference of cure rate between the experiment group(75%)and the control group(51.6%),with P＜0.01.There was no significant difference of total effective rate between the experiment group(96.6%)and the control group(88.3%),with P＞0.05.Conclusion Yin-Huang pills combined with Banlangen granule therapy was more effective in controlling acute upper respiratory infection,and this therapy caused few adverse effects.
