ABSTRACT
The paper summarized the explorations of public hospital pilots in the compensation mechanism and identified the following findings.For example,by means of fiscal support of public hospital infrastructure and development spending,cancellation of drug markup,higher service prices, and reformed payment mode of medical insurance,these hospitals have made initial changes at their business operating mechanism, motivation-guidance of compensation, and their makeup of medical revenue.In addition,such hospitals are found with lower cost of medical care per visit,and higher income of medical workers.The authors also pointed out such problems as inflated drug pricing and expenses,lack of scientific pricing mechanism for medical services,vague definition of policy-related losses,and old-fashioned practice of government investment and health insurance payment.Based on such findings,the paper advised to adjust health care prices by stages and to improve the management of health insurance and the coherence of compensation mechanism.
ABSTRACT
AIM:To establish HPLC fingerprints of Platycodon grandiflorum in different picking times in Henan province.METHODS:HPLC chromatography condition:Hypersil C_(18) column(250 mm×4.6 mm,5 μm);the mobile phase was acetonotrile with 0.05% phosphoric acid and the gradient elution mode was applied in chromatographic separation;The flow rate was 0.5 mL/min;The temperature of column was 30℃;the detective wavelength was set at 210 nm;RESULTS:The overall similarity in samples collected in autumn was higher than that in spring,and autumn was the appropriate for harvest.CONCLUSION:This method is simple and accurate with a good reproducibility.It provids a reliable scientific basis for the quality control of Platycodon grandiflorum.
ABSTRACT
Objective To observe the protective effect of high expression of mouse proxisome proliferator activated receptor γ1（PPARγ1）on free fatty acid （FFA）-induced βTC3 cell impairment. Methods The recombinant plasmid pcDNA3.1/PPARγ1 was generated with cloning and was stably transfected into pancreatic β TC3 cells. The expression was detected with semi-quantitative RT-PCR. Then the cell viability of wild βTC3 cells was compared with that of the βTC3 cells with high expressed PPARγ1 by MTT viability assay after they were exposed to high-level FFA for 48 hours. Results The sequencing results for amplified target gene showed that the sequence of PPARγ1 from Chinese Kunming mouse is similar to that of mouse PPARγ1 in Genebank, only the codon coding Asp at the site of 421 amino acid changed from AAU to AAC. PPARγ1 was efficiently expressed in βTC3 cells in vitro. The cell viability of wild βTC3 cells reduced after being exposed to high-level FFA for 48 hours（P0.05）. Conclusion The high expression of PPARγ1 could protect βTC3 cells from FFA-induced impairment
ABSTRACT
AIM: To establish HPLC-fingerprints and quantitatively determine platycodin-D from Platycodon grandiflorum.METHODS: HPLC analysis was carried out on Hypersil C18 column(250 mm ? 4.6 mm,5 ?m),with a mobile phase of acetonitrile-0.05 mol/L phosphoric acid system,gradient elution,with a flow at 0.5 mL/ min,an ultraviolet detection wavelength was at 210 nm for fingerprint and at 206 nm for platycodin-D,column tem-perature at 30 ℃.RESULTS: Twelve common peaks were identified in chromatograms with reference to platycod-in-D peak from the 18 batches of the samples.CONCLUSION: The method of the HPLC-fingerprint and quantita-tive analysis is rapid,simple and accurate with a good reproducibility and can be used for the quality control of Platycodon grandiflorum.
