RESUMO
Objective To investigate the awareness and administration of antidiabetic drugs in patients with diabetes in Huairou district of Beijing.Methods A questionnaire survey on knowledge and administration of antidiabetic drugs were conducted in 900 diabetic patients from 16 communities in Huairou district of Beijing from November 2014 to February 2015.The related factors influencing antidiabetic drug use were analyzed with logistic regression method.Results A total of 899 questionnaires were recovered. Results showed that the rate of metformin single use was the highest (23.7%, 213/899), the rate of combination use of metformin and acarbose was 11.8%(106/899), and that of metformin and glipizide was 17.1% (154/899).Survey showed that 65.9% (592/899) patients were compliant immediately for antidiabetic agents, 32.2% (290/899) were not immediately compliant, 1.9% (17/899) did not use antidiabetic agents.Logistic regression analysis showed that the factors affecting the use of antidiabetic agents were the types of medication (t=-4.351, P=0.000) , adverse effects of drugs (t=6.999, P=0.000), awareness of diabetes to health hazard (t=-10.969, P=0.000) and the doctor′s recommendation (t=-3.352, P=0.001).Conclusion The results showed that the administration of antidiabetic drugs in diabetic patients from Huairou district is basically followed the recommendation by 2013 edition of type 2 diabetes guidelines and the compliance rate of medication need to be further raised.
RESUMO
The first permanent molar caries and current status of sealant of 7 - 12-year-old students were surveyed in Huairou district of Beijing.Based on the World Health Organization and national oral health survey standards,cluster and stratified random sampling methods were used.The prevalence rate of deciduous tooth caries was 17.34％ with a decayed/missing/filled teeth (dmft) index of 0.30.The caries rate of females was higher than that of males (20.60％ vs.14.08％ ).The incidence of mandible was higher than that of maxillary.And there was no significant difference around the jaw.The rate of fissure sealant was 51.36％.The current status of first permanent molar caries in this district was in accordance with the characteristics of general epidemiological caries disease.An overall policy of early discovery,early diagnosis and early treatment should be practiced.
RESUMO
<p><b>OBJECTIVE</b>To study the efficacy of anti-telomerase siRNA in hepatocellular carcinoma both in vitro and in vivo.</p><p><b>METHODS</b>Lentvirus vectors contained anti-telomerase siRNA were conducted with a high performance homologous recombination system, and then were transduced into human hepatocellular carcinoma HepG2 cells. The telomerase activity was detected by RT-PCR, HepG2 cell proliferation was determined by MTT assay, and apoptosis was detected by TUNEL assay. The in vivo experiment was carried out by inoculation of HepG2 cells into nude mice and the tumor growth was measured and analyzed.</p><p><b>RESULTS</b>The growth of transfected HepG2 cells was significantly inhibited and the inhibition rate was 57.5% at the 8th day after transfection. The telomerase activity was significantly suppressed in vitro. The growth of transfected human hepatocellular HepG2 tumor in the nude mice was also significantly inhibited.</p><p><b>CONCLUSION</b>The results of this study demonstrate that the growth of hepatocellular carcinoma cells is effectively inhibited by transfection of anti-telomerase siRNA both in vitro and in vivo.</p>
