ABSTRACT
OBJECTIVE:To investigate the effects of UGT1A4142T>G polymorphism and blood concentration of valproic ac-id(VPA)on blood concentration of lamotrigine(LTG)in southern Chinese Han children with epilepsy,and to establish the predic-tion equation for quantitatively estimating blood concentration of LTG. METHODS:A total of 72 southern Chinese Han children with epilepsy selected from Guangzhou Women and Children's Medical Center during Jan. 2010-Sept. 2016 were given LTG+VPA. LC-MS/MS and enzyme amplified immunoassay were adopted to determine the blood concentration of LTG and VPA. RFLP-PCR was adopted to determine UGT1A4142T>G polymorphism. The relationships of age, gender, blood concentration of VPA, UGT1A4142T>G polymorphism and LTG concentration-to-dose-ratio (CDR) were also investigate. The prediction equation for blood concentration of LTG was established by multiple linear regression analysis. RESULTS:Age and blood concentration of VPA were positively related to CDR of LTG(r=0.225,0.300,P0.05). UGT1A4 TT,TG and GG genotypes were detected in 39,29,and 4 cases respectively;the frequencies of each genotype were in line with the Har-dy-Weinberg balance(P>0.05). CDR of LTG of TT genotype was significantly lower than those of TG and GG genotype,with sta-tistical significance(PG polymorphism(x4)were all related to blood concentration of LTG(PG polymorphism may associated with blood concentration of LTG. Established prediction equation can provide reference for precise medication in south-ern Chinese Han children with epilepsy.
ABSTRACT
Objective Study on efficacy of epileptic patients on treatment with modified Chaihu Guizhi De -coction(Chinese traditional medicine compounds )combined with anti-epilepsy drug.Methods 90 case of epileptic patients were randomly assigned to study group or control group ,45 case for each .The control group was treated only with anti-epilepsy drug , and the study group was treated with modified Chaihu Guizhi Decoction and anti -epilepsy drug.Observed and compared the treatment effect as well as the monthly average of seizure frequency of the epilepsy after treatment.Results The study group effective rate was 82.22%,which significant higher than the control group (64.44%).The study group's monthly average of seizure frequency was lower than the control group , the clinical effect between the control group and the study group were differences significantly (p<0.05).Conclusion Modified Chaihu Guizhi Decoction combined with anti -epilepsy drug can significantly reduce the seizure frequency of the epi-leptic patients in the treatment of epilepsy .It's worthy to be widely applied in clinical .
