OBJECTIVE:To promote the application of Personal data assistant(PDA)in the management and service of clinical medical information.METHODS:The application of PDA in medical fields and the chief function,the connotation of in_ formation service and whom the service aimed at were introduced.RESULTS:PDA was widely used in overseas medical infor-mation management and service for its distinct virtues of portability,speedy and accurate information service.CONCLUSION:PDA is an important vehicle in helping medicinal professionals’access to information.

OBJECTIVE:To study the effects of grape seed proanthocyanidin(GSP)on the transmembrane transport of sodium glycocholate (GA) and sodium taurocholate (TA) in colon glandular cell Caco-2. METHODS:Caco-2 model was used,and RP-HPLC was conducted to determine the contents of GA and TA in cell culture medium. The test was divided into GSP group, GA group,TA group,GSP+GA group and GSP+TA group,the transport volumes of transporting GA and TA from Transwell apical (AP)side to basolateral(BL)side by Caco-2 cell at 0,2,4,8 h were detected,respectively. RESULTS:The linear ranges of GA and TA were 0.05-1.2 mmol/L(R2=0.9999). With the time passing,transport volumes of GA and TA in BL site in GA group and TA group were sharply increased;while the transport volumes were obviously decreased after adding GSP,with statistical signifi-cance(P<0.01). CONCLUSIONS:GSP has inhibitory effect on the transmembrane transport of GA and TA in Caco-2 cell.

Persistent infection of hepatitis C virus (HCV) remains as a worldwide threat to public health,which involves a complex interaction between virus- and host related factors.HCV is classified as six genotypes and many subtypes according to the sequence heterogenecity.HCV genotype should be determined prior to treatment initiation since it plays a key role in selection of therapeutic regimen for chronic hepatitis C.Development of the antiviral treatment with protease inhibitor in combination with pegylated IFN-α and ribavirin requires the accurate determination of subtypes,e.g. 1a and 1b,as well.Genotyping methods based onsequenceanalysis, reversehybridizationorreal-timePCRhavebeendevelopedand evaluated.Some issues,however,should be settled to standardize the utility and result interpretation of these methods.More recently,host genotypes of IL28B have been found to be closely associated with HCV spontaneous clearance and the response to antiviral therapy.Moreover,polymorphisms in inosine triphosphate pyrophosphatase gene affect ribavirin-induced anemia.Therefore, host genotyping will be beneficial in predicting the outcome of chronic hepatitis C and monitoring the drug-induced adverse events.
