OBJECTIVE:To provide reference for improving propaganda level and effect of rational drug use. METHODS:Questionnaire survey was designed to investigate the recognition,attitude and demand of consumers in retail pharmacies,students in parts of pharmaceutical universities and their parents and patients in parts of hospitals in more than 10 provinces(autonomous re-gions and municipalities)for propaganda of rational drug use,and the results were statistically significant. RESULTS:The question-naires ranged from 100 to 2 000 in each province (autonomous region and municipality),and totally 11 700 questionnaires were sent out,11 490 were received with recovery of 98.2%;10 980 were effectively received with effective recovery of 95.6%. 78.4%respondents heard of the concept of rational drug use,proportion of young and middle-aged people in 18-44 years old was signifi-cantly higher than other age group,the proportion was significantly increased by the improvement of education,and the proportion of people closer to the city was higher(P<0.001);the respondents who can fully understand the content of the propaganda account-ed for 22.7%,while higher education held higher proportion on“fully understand”,and people closer to the city held higher pro-portion on“fully understand”and“partially understand”(P<0.001);only 9.5% respondents could fully trust propaganda activity, proportion of choosing“partially trust”was generally increased by the improvement of education(P<0.001);and 69.1% respon-dents hoped to obtain relevant knowledge,people who had more purchase frequencies showed stronger willing(P<0.001);the top 3 preferences of respondents for propaganda forms were“face to face guidance from physicians and pharmacists”,“reading drug in-structions”and“reading professional books”. CONCLUSIONS:With insufficient recognition on rational use of drugs,coverage of propaganda about rational drug use needs further expand,public understanding of propaganda contents about rational drug use is fairly limited and people’s trust level towards propaganda is not high,but the public has strong desires to obtain the knowledge about rational drug use. Therefore,various means should be adopted to improve the effects on propaganda of rational drug use.

OBJECTIVE To explore occurrence, distribution,and resistance profile of ?-lactamases in clinical isolates of Enterobacter cloacae for rational use of antibiotics in clinic. METHODS Susceptibility test to 13 antibiotics was also performed through disk diffusion test.ESBLs were conformed according to NCCLS.DIDST test was adopted to detect AmpC ?-lactamases in E.cloacae isolates. RESULTS Among 78 isolates collected,13(14.9%) produced AmpC ?-lactamases,24(27.6%) produced ESBLs,10(11.5%) produced both ?-lactamases.These produced(?-lactamases) strains resisted to almost all ?-lactams,except for imipenem.The ?-lactamases producers possessed seriously multi-and cross-drug resistance. CONCLUSIONS ESBLs and AmpC ?-lactams are the main mechanism of E.cloacae resistance to antibiotic.

AIM:To study the reversal effects of multidrug resistance by transfecting tumor necrosis factor ?(TNF-?) cDNA and multidrug resistant 1(MDR1) gene antisense RNA into multidrug resistant breast cancer cell line MCF-7/ADR.METHODS:The recombinant vector of enhanced green fluorescent protein(EGFP) with MDR1 antisense RNA and recombinant vector of red fluorescent protein(DsRed2) with TNF-? cDNA were constructed by RT-PCR and DNA recombinant techniques.The recombinant vectors were transfected into multidrug resistant breast cancer cell line MCF-7/ADR.The cell growth curves,cell apoptosis rates,MDR1 gene expression at mRNA and P-gp levels,and the sensitivity to ADR were determined before and after the transfection.RESULTS:After the transfection,cells showed lower growth rate,higher apoptosis rate,lower MDR1 expression at mRNA and P-gp levels,and the sensitivity to ADR increased significantly.CONCLUSION:Transfection of TNF-? cDNA and MDR1 antisense RNA into multidrug resistant breast cancer cells may have good effects on reversal of multidrug resistance.

Objective To investigate the effect of hydroxysafflor yellow A (HSYA) on neurogenesis of the dentate gyrus organotypic hippocampal slice cultures after oxygen-glucose deprivation (OGD).Methods The 3-day-old Sprague Dawley rats were used to making organotypic hippocampal slices.They were randomly divided into four groups:a blank control group,a saline control group (giving 1 mL normal saline after OGD),a high-dose HSYA group (giving 1 ml,0.072 mg/ml HSYA after OGD),and a low-dose HSYA group (giving 1 ml,0.036 mg/ml HSYA after OGD) (n =6 slices in each group).Nestin and 5-bromo deoxyuridine nucleoside imnune fluorescence method were used to double-label the proliferation of neural stem cell (NSC).Results There were significant differences in NSC numbers among the different time points before and after OGD in slices of each group (all P ＜0.001).After OGD,the proliferation of NSC numbers reduced significantly in each group,cell proliferation increased siginificantly at day 3,and the proliferation of NSC number at day 6 was lower than that at day 3,but they still higher than those before OGD.There were significant differences in the proliferation of NSC numbers among the blank control,the saline control,high-dose HSYA,and low-dose HSYA groups (F =947.077,P ＜0.001).Observing from each time point,in addition to before OGD,the proliferation of NSC numbers at all other time points had the following relations:the blank control Group ＞ the high-dose HSYA group ＞ the low-dose HSYA group ＞ the saline control group (all P＜0.001).Conclusions HSYA may alleviate OGD to the NSC injury and contribute to neurogenesis.
