Overexpression of OPN in hepatocytes following fluorosis after excess fluorine intake was involved in liver damage process, which was enhanced by deficiency of calcium and protein intake. The results also demonstrated that the development of fluorosis in Guizhou province was correlated with local baking staple corn as a way of excess intake of fluorine and deficiency of calcium/protein intake.

Through researching the oil and gas in many companies, such as the Daqing Oilfield, Changqing Oilfield and the West-East Gas Pipeline Company and so on, we found that the production and construction of oil and gas at different stages influence the soil erosion vary greatly, including the exploration in oil and gas has a little effect on soil erosion, but oil and gas field surface engineering and pipeline construction impact on soil erosion greatly, and limited impact on soil erosion in oil and gas development, and long-distance pipeline operators had no effect on soil erosion.Oil and gas companies have taken appropriate preventive measures in the soil erosion and have achieved good control effect.
