As a functional membrane protein, drug transporters play an important role in the absorption, distribution, metabolism and excretion of drugs. The functional omission or inhibition of drug transporters is believed to be involved in the drug-drug interaction and pathogenesis of certain diseases. Understanding the function of drug transporters is highly significant in terms of pharmacokinetics, pharmacodynamics and toxicity of drugs. This article summarized the methods for the study of drug transporters in vitro and in vivo.

Posterior circulation iscbemia refers to the transient iscbemic attack and the cerebral infarction in vertebrobasilar artery system,its prognosis is not as good as anterior circulation ischemia,and its treatment is similar to that of anterior circulation ischemia.However,because of the mortality of basilar artery occlusion is higher,usually more aggressive treatment should be considered,such as thromholytic therapy(especially intra-arterial thromholysis)and endovas- cular therapy,and the therapeutic time window is much longer.This article reviews the treatment of anterior circulation ischemia.

Objective To investigate the effect of rapamycin(RPM)on hepatic interleukin-10(IL-10)gene and acute liver injury in rats with postburn Staphylococcus aureus sepsis.Methods Fifty male Wistar rats were randomly divided into four groups:normal control group,scald control group,postburn sepsis group,and RPM treatment group.Tissue samples from liver and plasma were collected to determine IL-10 mRNA and protein expressions,and liver function parameters were also measured.Results Compared to postburn Staphylococcus aureus sepsis group,in RPM treatment group hepatic IL-10 mRNA expression and plasma IL-10 were significantly increased at 0.5 hour after RPM treatment(P

The association of polymorphisms of calcium channel?1 subunit ( Cav1.1 ) gene ( - 1551T/C at exon 11 ) with thyrotoxic periodic paralysis (TPP) was investigated by PCR-RFLP.The distributions and frequencies of - 1551TC + CC genotype and C allele in TPP group were significantly higher than those in hyperthyroidism (HT) and normal control (CON) groups.There was no statistic difference between HT and CON groups.Cavl.1 gene - 1551TC + CC genotype and allele may contribute to the development of TPP in male HAN population from North China.

Objective To explore the efficacy of transvaginal color Doppler sonography(TV-CDS)in the diagnosis and differential diagnosis of cornual pregnancy.Methods The characteristics of gray-scale and color Doppler ultrasonography of 30 patients with cornual pregnancy confirmed by surgery and pathology,were studied retrospectively.The position,size,figure,echogenicity and vascular pattern of the pregnancy tissue were evaluated,and the resistance index was calculated.Results The 30 patients were classified into two groups:group A with typical gestational sac and group B with abnormal mass in the area of corner.The overall diagnostic accuracy for these patients was 43.3%(13/3)and classified as 90%(9/10)accuracy for group A and 20%(4/20)for group B.Among the 17 patients who were misdiagnosed or diagnosed unclearly by TV-CDS,one patient in group A was misdiagnosed as a normal pregnancy,11 patients in group B were misdiagnosed as gestational trophoblastic disease and the rest 5 patients in group B were diagnosed unclearly.Conclusions TV-CDS is useful for differential diagnosis of cornual pregnancy.The cornual pregnancy with abnormal mass is usually misdiagnosed,and therefore clinical features and laboratory data should be fully evaluated for its diagnosis.
