OBJECTIVE:To put forward some suggestions for the development of e-commerce in China's pharmaceutical retail chains.METHODS:To drawn on experiences from the western developed countries in developing B to C pharmaceutical e-commerce and analyzed the problems existing in China's pharmaceutical industry.RESULTS & CONCLUSIONS:To develop e-commerce in China's pharmaceutical retail chains,the cooperated supervision of the concerned governmental departments is indispensable,in addition,the level of informatization should be improved step by step and the network of retail chain should be relied on to offer customer-centered services.

Objective To investigate the effect of nasal continuous positive airway pressure (NCPAP) on cardiac function in children with pneumonia complicated with heart failure.Methods Twenty-two children with pneumonia complicated with heart failure were selected in emergency room of Beijing Children′s Hospital Affiliated to Capital Medical University from Oct.2008 to Mar.2009,aged 1 month and 15 days to 2 years and 8 months,prospective clinical study.Cardiac function[including cardiac index(CI),heart rate(HR) and stroke volume index(SVI)] before and after NCPAP 0.04-0.05 kPa for 30 minutes were monitored by ultrasonic cardiac output monitoring(USCOM).Results After the application of 0.04-0.05 kPa NCPAP for 30 minutes,the heart rate decreased signi-ficantly [(173?10) beats/min vs (151?13) beats/min P0.05].Conclusions NCPAP might improve cardiac function by increasing stroke volume index and decreasing heart rate and respiratory rate in children with pneumonia complicated with heart failure.

OBJECTIVE: To propose some suggestions towards the operation and development of online pharmacies in China.METHODS: From the following three aspects: website design,information provision,and customer service,the paper introduced and compared the websites of three approved online pharmacies,which include Jingwei Pharmacy,Shanghai Pharmacy and Jinxiang Pharmacy.RESULTS & CONCLUSIONS: To develop online pharmacies,the information display should be customer-centered,new marketing plans based on the characteristics of the internet should be developed;meanwhile,the operators of online pharmacies should help consumers developing an awareness of drug safety and offer them corresponding services.

Objective: To study the quality of sleep and the quality of life in the Chinese People's Armed Police Forces of Guangdong province. Methods: By random unitary sampling, the PSQI Scale and the WHOQOL-BREF Scale were used in 1170 people of the Chinese People's Armed Police Forces in Guangdong province. Results: The total score of the quality of sleep in the Chinese People's Armed Police Forces of Guangdong province was 6.73?3.13. The scores of physiological, psychological, social, and environmental domains of the quality of life for the good-sleepers were higher than that of the ordinary-sleepers and the bad-sleepers. The scores of the four domains of the quality of life were correlated with the scores of PSQI negatively. Conclusion: The quality of sleep could influence the quality of life.

Abstract Objective:To explore homology in mage-A family and find some common epitopes recognized by cytotoxic T lymphocyte(CTL) to oppose tumor escape.Methods:The amino acid sequence,differents open reading frame(ORF) and the known CTL epitope of themember of MAGE-A family,were analyzed using DNAstar software, and phylogenetic tree is also constructed. Results: MAGE-A family shareidentity nucleotide 57.6% - 98.0%,the phylogenetic tree showed that they are derived from a common ancestor at different time, as well asfound some CTL epitopes high similarity. Conclusion: MAGE-A family come from common an ancestor, but they bave many differences in thepattern of expression in tumor.This study can help to find the best CTL epitope vaccine to cure tumor.

Objective To explore the accuracy of the ultrasonic cardiac output monitor(USCOM) device for estimation of children's cardiac output.Methods We conducted a prospective study in Beijing Children's Hospital.Sixty healthy children were enrolled in this study.We evaluated the accuracy of USCOM monitor device in the measurement of cardiac output by comparing with the measurements obtained by the M-Teichholz formula and the Doppler aortic blood flow method.Results The data from the USCOM monitor device had better consistency with those from the M-Teichholz formula (r=0.88,P<0.05),and there was no significant difference (P>0.05) between the two methods.The similar results were found between the USCOM method and the Doppler aortic blood flow method (r=0.83,P<0.05).Conclusion This study shows that cardiac output monitoring by USCOM is accurate,and USCOM is a promising technique in cardiac output monitoring.

Objective To study the changes of platelet, endothelial functions and fibrinolytic activity of coronary artery disease (CAD) patients before and after PTCA Methods 26 negative patients of coronary angiocardiography (CAG) serving as negative control and 16 positive ones of CAG but unsuitable for PTCA as positive control, we observed the dynamic changes of plasma P selectin? thrombomodulin and plasminogen activator inhibitor 1 of 24 CAD patients before and after PTCA Results In PTCA group, the levels of plasma Ps and TM were higher 5 min after PTCA than those before PTCA ( P
