Abstract:
Objective To investigate the genetic association between mutation in cytochrome P450 1A2 (CYP1A2) gene and Erxian suop response. Methods Forty-eight patients with male climacteric syndrome of both Yin and Yang deficiency received a treatment of erxian suop with three months. The severity of symptoms and responses to Erxian suop were quantizated by the method of Department of Psychology in Istanbul Bosphorus University and Clinical Research Guidance Principle on New Drug of Traditional Chinese Medicine published by China. A single nucleotide polymorphism (SNP) at position 2964 (G-A) of CYP1A2 gene were identified by polymerase chain reaction (PCR) in order to analyse the relationship between Erxian response and CYP1A2 single nucleotide polymorphism. Results Statistical analysis showed there was no significant difference among genetype and genetype distribution of CYP1A2 G2964A between the patients and control group. The genotype of the 16 patients among 32 effective patients was G/G (56.25%). The genotype of the 11 patients among 16 ineffective patients was G/A (68.75%). There was no significant difference in symptoms, physical sign between the two groups at the pre-treat and post-treat. Also the two groups had no significant difference among the score of major symptoms and hyposymptoms. Conclusion The patients with genotype of G/G have higher efficiency, while with genotype of G/A have lower efficiency among patients with CYP1A2 G2964A gene when treated with erxian soup.
