OBJECTIVE:To provide reference for further comprehensive evaluation of the improvement of the accessibility of family medicines after the implementation of the new health care reform. METHODS:Sampled as 180 households from 2 urban ar-eas,2 counties and 2 rural areas in Chengdu,a questionnaire survey was adopted based on the WHO’s manual for the Household Survey to Measure Access and Use of Medicines to investigate the situation of drug use,storage and accessibility,and the results were statistically analyzed. RESULTS:Totally 180 questionnaires were sent out,179 were effectively received with effective recov-ery of 99.44%. In the terms of medicines taken for the acute illness,there were more than 60% rural households obtained drugs from the public health care facilities,while more than 60% counties households purchased drugs in public medical and health insti-tutions;in the terms of medicines taken for the chronic illness,the proportion of households reporting a chronic illness who did not take any medicines was low(3.80%);in terms of medicines storage,the proportion of households without reserve drugs was low (13.41%). In terms of drug accessibility,the proportions of respondents who agreed that the location and opening hours of their public healthcare facility were convenient were high;there was no situation for“patients did not take prescribed drugs because med-icines were not available at the healthcare facility and drug store”,while more than 95% respondents who agreed that drugs were available at their public health care facilities and drug stores;the essential medicines in the household use of chronic drugs in Chengdu accounted more than 60%;more than 85% can afford the drug costs,while the proportion of the monthly costs for acute illness and chronic illness in the total month costs was low;the health insurance coverage reached 90% in the survey households, but the proportions of households which could reimburse acute,chronic illness drug cost were lower(14.13% and 12.66%). CON-CLUSIONS:At present,the level of drug accessibility in Chengdu is high;the implementation of National Essential Medicines System has a positive effect on reducing the economic burden of chronic disease family. But there are shortcomings in the Medicare reimbursement levels and antibiotics use,it is suggested to take effective measures to solve it,such as exploring the stable and ef-fective medical insurance fund raising channels,improving the compensation level and the level of insurance reimbursement,formu-late and implement the corresponding antibacterial drugs supervision system and regulate the rational use of antibiotics in residents.

Objective To explore effect of isoorientin on gastric cancer cell autophagy.Methods Isoorientin and autophagy activator and effect of inhibitors on proliferation of human gastric cancer cell line SGC-7901 by MTT assay.Cell apoptosis was detected by flow cytometry.Production of autophagy lysosomal in gastric cancer SGC-7901 cells was obseroved by AO and MDC staining.Characteristic expression of autophagy protein was analysed by Western blot.Results MTT assay indicated that isoorientin could inhibit gastric cancer cell growth, RAP has the same effects, but 3-MA inhibition of apoptosis.Flow cytometry was used to detect the apoptosis rate of isoorientin and RAP could promote cell apoptosis , while 3-MA had the opposite effect.In AO staining, the red light appeared in the cells, and the green fluorescence appeared in the cells of MDC staining, which showed that there was an autophagy in the cells.Western blot test found the isoorientin was cell autophagy specific protein LC-3II, Beclin-1 expression increased, 3-MA suppressed the expression of the two proteins, and RAP had the opposite effect.Conclusion Isoorientin could induce apoptosis in gastric cancer SGC-7901 cells, autophagy is involved in the process of death.

Objective To compare the pharmacodynamics of common Bletilla striata powder(80 and 200 meshes) with ultra-fine powder of B.striata on experimental gastric ulcer in rats and to clarify how much the dose of B.striata was decreased after superfine comminution.Methods The models of gastric ulcer were set up by anhydrous alcohol and acetic acid to measure the gastric ulcer area and count out the inhibitory rate;The tissue slice of gastric ulcer cicatrix was got far HE staining.Based on the viewpoint of pathology the morbid state was observed.Results B.striata powder could decrease the gastric ulcer area significantly,and the groups of ultra-fine powder were advantaged to the others.Conclusion After superfine comminution,the potency of B.striata can be improved with its dose reducing.It is good for mo-dernization of making dosage forms.
