ABSTRACT
OBJECTIVE:To provide basis for the establishment of warfarin individualized administration model that is suitable for Uighurian patients in Xinjiang. METHODS:The genotypes of CYP2C9 and VKORC1 in 200 Uighurian patients in xinjiang were detected and compared with the genotypes and allele frequency of different ethnic populations in world. RESULTS:The frequency of CYP2C9*1/*1 homozygous wild type in Xinjiang Uighurian patients was lower than South Korea,Japan,the United States and Han nationality in China,higher than Turkey;the frequency of *1/*2 heterozygous mutant was lower than Turkey,Sweden and the United Kingdom,higher than South Korea,Japan and Han nationality in China;the frequency of *1/*3 heterozygous mutant was higher than Japan,South Korea,Han nationality in China,the United Kingdom and the United States;the frequency of *3/*3 was higher than the populations above(P<0.05). *1 allele in Xinjiang Uighurian patients was lower than Han nationality in China,Ja-pan,South Korea and the United States,higher than Turkey(P<0.05). *2 allele was higher than Han nationality in China,Japan and South Korea,lower than Turkey,Sweden and the United Kingdom(P<0.05). *3 allele was higher than Han nationality in Chi-na,Japan,South Korea,Sweden,the United Kingdom and the United States(P<0.05). The frequency of VKORC1-1639AA in Xinjiang Uighurian patients was higher than the United States Sweden,the United Kingdom,lower than Singapore,Japan,Taiwan China and Han nationality in China. The frequency of type AG was higher than Singapore,Japan,Taiwan China,Han nationality in China. The frequency of type GG was higher than Singapore,Japan,Taiwan China,Han nationality in China,lower than the United States,Sweden and the United Kingdom(P<0.05). Type A allele in Xinjiang Uighurian patients was lower than Han nation-ality in China,Taiwan China,Japan and Singapore,higher than the United States,Sweden and the United Kingdom;type G was higher than Han nationality in China,Taiwan China,Japan and Singapore,lower than the United States,Sweden and the United Kingdom(P<0.05). CONCLUSIONS:The distribution of CYP2C9 and VKORC1 gene polymorphism in Uighurian patients in Xin-jiang are obviously different from Asian,European and American populations.
ABSTRACT
Objective To increase the solubility and relieve the mucous irritation of cantharidin (CA) by preparing cantharidin-hydroxypropyl-β-cyclodextrin (CA/HP-β-CD) inclusion complex.Methods The inclusion complex was prepared by co-evaporation method and characterized by differential scanning calorimetry (DSC),X-ray diffractometry (XRD),and nuclear magnetic resonance (NMR).Results The disappearance of CA as well as the shift of exothermic peaks shown in DSC results indicated the complexation phenomenon.XRD results showed that the crystalline CA pattern had disappeared,and in NMR results,H-5 shifted from δ 3.731to 3.695 after complexation and H-2 shifted from δ 3.626 to 3.598,which suggested that part of the drug had entered the HP-β-CD cavity to form an inclusion complex.The solubility increased 10.3 times after complexation and the mucous irritation of CA was relieved remarkably.Conclusion Through complexation with HP-β-CD,the solubility and dissolution rate of CA are improved significantly,and the irritation of musous is relieved.
