Objective To explore the correlation between aspirin resistance and COX-1, P2Y1, GPIa and GPIIIa gene polymorphism. Methods 35 case with aspirin resistant were selected and were given aspirin enteric coated tablets for oral treatment, 14 days.After the determination COX-1, P2Y1 and GPIa and GpIIIa gene polymorphism of each patient were analysis.Results The genotype AA of COX1 (A-842G) locus and CC of COX1 (C50T) locus was higher than other genotype (P<0.05);AG of P2Y1 (A1622G) locus genotype and CC of P2Y1 (C893T) locus genotype was higher than other genotype (P<0.05);CT of GPIa (C807T) locus genotype and GA of GPIa (G873A) locus genotype was higher than other genotype (P<0.05);PLA1/A1 of GPⅢa(T1565C)locus genotype was higher than other genotype (P<0.05).Conclusion P2Y1 (C893T), GPIa (C807T) allele is associated with aspirin resistance,With COX-1 (A-842G, C50T), GPIa (G873A), GP III A (T1565C), P2Y1 (A1622G) allele is more likely to induce the occurrence of aspirin resistance.

Objective In order to provide a reference for optimizing the dosage regimen of carbamazepine and valproate in pediatric epilepsy patients .Methods Pharmacist consulted one pediatric epilepsy patient with traumatic brain injury for post operation epilepsy treatments .The abnormal plasma concentration of carbamazepine and valproic acid was analyzed with the population pharmacokinetic (PPK) model built by this team .New medication regimen was proposed and the predictive capabili-ty of this model was evaluated .Results Seizures in this patient have been effectively controlled .Conclusion Pharmacist can optimize the antiepileptic drug treatment with PPK model and achieve rational drug use clinically .
