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

Objective To observe the effect of intravenous injection of different doses of propofol on the ceil apoptosis and NF-kB p65 in the acute lung injury(ALl)induced by LPS in rats.Method Sixty SD rats were randomly(random number)divided into five groups,namely,control(NS)group,Au model group and propofol intervention groups(P1,P2,P3 groups).The lung injury was evaluated by using microscopy with hematoxylin and eosin(HE)staining and arterial blood gas,and Western blotting Was applied to evaluating the nuclear translocation of NF-KB P65 in lung tissues.The apoptosis rate of lung tissue Was determined by flow cytometric analysis.Results Lung injury in model group reached the pathologic criteria of acute lung injury,and it was attenuated apparently in propofol intervention groups(P1,P2,P3 groups)in dose-dependent manner.Western blotting results showed that the nuclear translocation of NF-KB P65 and the apoptosis rate increased significantly in ALI model group compared with control group(P<0.05),and decreased in propofol intervention groups compared with ALl model group(P<0.05).Conclusions Propofol Can attenuate acute lung injury induced by LPS in rats,and significantly inhibit the nuclear translocation of NF-KB P65 and the cell apoptosis in lung tissues.The effect of propofol attenuating acute lung injury induced by LPS in rats may be attributed to the inhibition of nuclear translocation of NF-KB P65and ceil apoptosis in lung tissues.

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 provide reference for the establishment of prevention and control measures for medication errors. METHODS:Based on JCI standard,51 cases of medication error reported by ADE information platform of our hospital in 2012 were summarized,and analyzed in terms of error type,error time,working life of responsible person,etc. The prevention and con-trol strategies were introduced. RESULTS:Referring to related requirements of JCI standard,medication errors reduced significant-ly during 2013-2014 through personnel training and education,system improvement and process optimization. CONCLUSIONS:Medication errors surveillance and control is important for the promotion of rational use of drugs. JCI standard has played an impor-tant role in monitoring and preventing medication errors.
