RESUMO
Objective To detect the characteristics of acquired immune deficiency syndrom (AIDS) epidemic in Lanzhou City from 2011 to 2018 and the spatiotemporal aggregation of human immunodeficiency virus (HIV) infection and AIDS patients at county level, and to provide scientific reference for prevention and control of HIV/AIDS in Lanzhou City. Methods The space-time scanning and measurement method was used to detect, test, and analyze the spatiotemporal aggregation of HIV/AIDS reports. The aggregation characteristics of the AIDS epidemic in time and space were obtained, and the detection results were visualized by ArcGIS 10.3. Results From 2011 to 2018, there were four statistically significant high spatial and temporal aggregation areas in HIV/AIDS in Lanzhou City. One type of gathering area was Chengguan District, Anning District and Gaolan County. The gathering time was from 2015 to 2018 (LLR=108.63,RR=2.02, P<0.001); The second type of aggregation area was the Qilihe area, which gathered from 2015 to 2018 (LLR=60.93,RR=2.11, P<0.001). It was detected that the Qilihe District had a type Ⅰ aggregation of heterosexual transmission from 2014 to 2017, and Gaolan County, Anning District and Chengguan District had a type II aggregation of heterosexual transmission from 2015 to 2018; It was detected that Gaolan County, Anning District and Chengguan District had a type of gathering of same-sex transmission from 2015 to 2018; In the Qilihe District, there was a second category of same-sex communication between 2017 and 2018. Conclusion The HIV/AIDS epidemic in Lanzhou City has spatiotemporal aggregation regardless of the number of reports or different transmission routes. The prevention and control situation is still severe and should be highly valued by the relevant local departments.
RESUMO
<p><b>OBJECTIVE</b>To study the effect of liver fatty acid binding protein(L-FABP) and fatty acid transport protein (FATP4) in the development of nonalcoholic fatty liver disease (NAFLD) in rats.</p><p><b>METHODS</b>The expression of L-FABP and FATP4 genes was examined in fatty liver rats by reverse transcription and polymerase chain reaction amplification and Western blot methods.</p><p><b>RESULTS</b>In the high fat diet group (F), mRNA and protein expression of L-FABP and FATP4 were increased at 2 weeks, and they increased remarkably at 12 weeks (P < 0.05; L-FABP mRNA F=124.9, protein expression F=92.6; FATP4 mRNA F=602.9, protein expression F=108.8).</p><p><b>CONCLUSION</b>The high expression of L-FABP and FATP4 at the early stage is an adaptive reaction of the body, With the advanced expression of the L-FABP and FATP4, it can lead to a fatty acid disequilibrium and then result in nonalcoholic fatty liver disease in the rats.</p>
