Abstract
BACKGROUND The pharmacokinetics (PKs) and pharmacodynamics (PDs) of telmisartan varies among the individuals, and the main causes remain unknown. The aim of this study was to evaluate the impact of ORM1, as well as ABCC2, ABCB1, ABCG2 and SLCO1B3 polymorphisms, on the disposition of the drug and BP change after taking 40 mg telmisartan in 48 healthy Chinese males. METHOD A total of 48 healthy males were included in this trial. Every volunteer ingested a single dose of 40 mg telmisartan, and the plasma drug concentration and blood pressure (BP) were measured up to 48 h. RESULT In this study, the area under the plasma concentration-time curve (AUC) in the heterozygotes of ORM1 113AG was higher than that in the wild-type homozygotes, AUC(0-48) (113AA vs. 113AG, 1,549.18±859.84 ng·h/ml vs. 2,313.54±1,257.71 ng·h/ml, P = 0.033), AUC(0-∞) (113AA vs. 113AG, 1,753.13±1,060.60 ng·h/ml vs. 2,686.90±1,401.87 ng·h/ml, P = 0.016), and the change(%) of the diastolic blood pressure (DBP) from the baseline BP value also showed a significant difference between the ORM1 113AG and 113AA genotypes at 5 h after taking telmisartan (P = 0.026). This study also showed that the allele of ABCC2 C3972T would affected the disposition of telmsiartan and the DBP change significantly after taking the drug. However, the common SNPs of ABCG2 C421, ABCB1 C3435T, and SLCO1B3 T334G showed no impacts on the PKs of telmisartan or BP change(%) in our trial. CONCLUSION The ORM1 A113G polymorphism was associated with the PKs variability after taking telmsiartan, as well as ABCC2 C3972T. The heterozygotes of ORM1 113AG showed a larger AUC and a notable BP change(%) from the baseline compared with the wild-type. TRIAL REGISTRATION Chinese Clinical Trial Registry ChiCTR-TNC-10000898.

Abstract
PURPOSE ORM1 is a plasma drug binding protein. Its polymorphism rs17650 (S>F) has been reported to be an important factor affecting the binding ability and effect of antiretroviral protease inhibitors. The aim of this study was to determine whether the ORM1 rs17650 polymorphism also influences warfarin therapy. METHODS A total of 191 Chinese patients with steady-dose warfarin therapy were enrolled in this study. The patients were studied for warfarin maintenance dose, the ORM1 rs17650 polymorphism, and two polymorphisms previously demonstrated to affect warfarin response [CYP2C9 rs1057910 (3) and VKORC1 rs7294 (-1639 G>A)]. RESULTS Warfarin dose was partially correlated with the VKORC1 rs7294, CYP2C9 rs1057910 and ORM1 rs17650 polymorphisms. Patients carrying the wild-type of these three genes (n = 96) took a mean dose of 3.0 ± 1.1 mg warfarin, which was significantly higher than that taken by the 52 S patients (2.7 ± 0.7) and 11 S S patients (2.5 ± 0.6 mg) (p = 0.048). CONCLUSION We identified ORM1 as another polymorphic gene affecting warfarin dose requirements. ORM1 S carriers require lower maintenance doses to achieve and maintain an optimal level of anticoagulation.

Abstract
British history contains several periods of major cultural change. It remains controversial as to how much these periods coincided with substantial immigration from continental Europe, even for those that occurred most recently. In this study, we examine genetic data for evidence of male immigration at particular times into Central England and North Wales. To do this, we used 12 biallelic polymorphisms and six microsatellite markers to define high-resolution Y chromosome haplotypes in a sample of 313 males from seven towns located along an east-west transect from East Anglia to North Wales. The Central English towns were genetically very similar, whereas the two North Welsh towns differed significantly both from each other and from the Central English towns. When we compared our data with an additional 177 samples collected in Friesland and Norway, we found that the Central English and Frisian samples were statistically indistinguishable. Using novel population genetic models that incorporate both mass migration and continuous gene flow, we conclude that these striking patterns are best explained by a substantial migration of Anglo-Saxon Y chromosomes into Central England (contributing 50%-100% to the gene pool at that time) but not into North Wales.

Abstract
Human orosomucoid (ORM) is a major binding protein for various basic drugs. The genetic polymorphisms of ORM could be responsible for interindividual variation in the plasma binding of basic drugs, which might influence their effects or toxicities. The genetic polymorphisms of ORM on the Han population in Nanjing of China were analyzed by isoelectric focusing (IEF) on polyacrylamide gels following by immunoblotting. After desialylation of sera from 220 unrelated Chinese subjects, the band patterns of ORM showed that the polymorphism of the structural locus ORM1 is controlled by three codominant autosomal alleles, ORM1*F1, ORM1*F2 and ORM1*S, which presented five phenotypes, ORM1 F1, ORM1 S, ORM1 F1F2, ORM1 F1S, and ORM1 F2S. The allele frequencies were: ORM1*F1=0.7068, ORM1*F2=0. 0182, ORM1*S=0.2750. The results presented in this paper indicate the ORM1 locus is polymorphic and the ORM2 locus is monomorphic in sera from the Han population in Nanjing of China.

Abstract
According to history, the population of the British Isles derives its genepool from a succession of invaders and immigrants. The settlement pattern of these invaders gave rise to a patchwork of genepools, shown in previous genetic surveys. Specimens from 1117 blood donors of regionally subdivided East Midlands (Derbyshire, Nottinghamshire and Leicestershire) were analysed for 18 conventional genetic systems (blood groups, serum proteins and red cell enzymes), according to place of residence. Significant differences exist among the five geographically defined sub-populations, and it is argued that these are derived from the historical settlement of continental European populations in the region, especially the Danes and the Vikings.
