ABSTRACT
Alcoholic fatty liver disease (AFLD) is a pathological change of liver steatosis caused by long-term heavy alcohol consumption. The mechanism of AFLD formation mainly includes abnormal lipid metabolism, immune-inflammatory reaction, intestinal flora imbalance, alcohol metabolism enzyme disorder and so on. In recent years, numerous studies have confirmed that microRNA (miRNA) plays an important role in diagnosis and treatment of many diseases, the molecular regulatory mechanism of miRNAs involved in AFLD formation has also become a research focus. The majority of studies have explored the role of miRNAs in AFLD formation by exploring the targeting role of miRNAs of key genes in the formation pathway of AFLD, and establishing an expression network with genes that promote or inhibit the expression of downstream genes of this signaling pathway. In present paper, the important miRNAs in the formation pathway of AFLD and their regulatory mechanisms in AFLD are reviewed, so as to provide theoretical basis for further understanding the function of miRNAs and its relevant mechanisms in AFLD.
ABSTRACT
<p><b>OBJECTIVE</b>To understand the changing trend of occupational hazard of industries in Shunde area and to provide the scientific evidence for the prevention of occupational diseases.</p><p><b>METHODS</b>The pre-evaluation of occupational hazard was carried out for the construction projects. The data about employee number scale, industry species, occupational hazard factors, hazard levels and prevention measures for construction projects were collected and analyzed. The data of Shunde Occupational Health Survey in 2011 served as the control data.</p><p><b>RESULTS</b>There were 258 construction projects in 2010 and 2011, in which the proportions of medium and large scales increased to 8.1% and 2.4% respectively, the proportions of the furniture and chemical industries decreased from 25.6% or/and 5.1% to 2.7% or/and 1.8%, the proportions of the high-tech industries increased from 1.8% to 9.2%. The proportions of the projects with serious, medium and slight occupational hazard levels were 4.3%, 67.8% and 27.9%, respectively. The proportions of the projects with harmful chemicals, dusts and physical factors were 34.2%, 46.8%, 42.6%, respectively.</p><p><b>CONCLUSION</b>The feature of occupational hazard in Shunde industries has changed at upgrading stage. We should pay attention to the prevention of occupational diseases in high-tech industries.</p>
