The body is equipped with kinds of transporters which generally exist in liver,kidney,and intestine.Multidrug and toxin extrusion proteins(MATEs;SLC47A)are predominantly expressed in the brush-border membrane of proximal tubule epi-thelial cells in the kidney and the canalicular membrane of hepa-tocytes.Functionally,MATEs act as efflux transporters for or-ganic compounds.The article discusses type,structure,poly-morphism and function of MATE1and MATE2-K,and also dis-cusses the effect of single nucleotide polymorphisms (SNPs)in the SLC47A1 gene and SLC47A2 on the pharmacokinetics and pharmacodynamics of metformin and platinum-based chemothera-peutic agents.

OBJECTIVE:To establish a method for simultaneous determination of the confents of calycosin-7-glucoside,calyco-sin and formononetin in Shenqi granule. METHODS:HPLC was performed on the column of Welch Ultimate XB-C18 with mobile phase of acetonitrile-0.2% Formic acid solution (gradient elution) at flow rate of 1.0 ml/min,detection wavelength was 250 nm, column temperature was 35 ℃,and injection volume was 10 μl. RESULTS:The linear range of sample quantity was 0.008-0.32 μg for calycosin-7-glucoside(r=0.999 9),0.005-0.20 μg for calycosin(r=0.999 7)and 0.007-0.28 μg for formononetin(r=0.999 8);RSDs of precsion,stability and reproducibility tests were no more than 1.59%;recoveries were 98.17%-99.17%(RSD=0.67%, n=6),98.03%-99.66%(RSD=0.57%,n=6) and 98.16%-99.12%(RSD=0.43%,n=6). CONCLUSIONS:The method is sim-ple,accurate and reliable,and can be used for the content determination of Shenqi granule ofiso flavones.

Objective To explore the effects of continuing care on the quality of sleep and neurological function rehabilitation in patients after stroke. Methods 60 patients with sleep disorder and hemiplegia after stroke discharging from our hospital during January to December 2014 were randomly assigned to control group (n=30) and intervention group (n=30). The control group received routine discharge instruction, while the intervention group received continuing care. They were assessed with Pittsburgh Sleep Quality Index (PSQI), simplified Fugl-Meyer Assessment (FMA) and modified Barthel Index (MBI) were when discharged and 3 months after intervention. Results The scores of PSQI were lower, the scores of FMA and MBI were higher in the intervention group than in the control group 3 months after intervention (P<0.05). The nursing satisfaction was higher in the intervention group than in the control group (P<0.001). Conclusion Continuing care could improve the sleep quality, and promote the neurological function recovery for patients with sleep disorder after stroke.
