Integrative analysis of the molecular signature of target genes involved in the antitumor effects of cantharidin on hepatocellular carcinoma.

Background: Cantharidin (CTD) is the active ingredient of Chinese medicine, which has been traditionally used in multiple cancers treatment, especially in hepatocellular carcinoma (HCC). However, a comprehensive analysis of the CTD-related molecular mechanism is still necessary to understand its functions in HCC treatment. This study aimed to reveal the novel molecular targets and regulatory networks of CTD in HCC.

[Kinetics of adsorption of Pb2+ onto small river sediment].

The batch experiments of adsorption of Pb2+ onto small river sediments were conducted. The kinetics of the sorption process was analyzed. The results showed that the equilibrium time of adsorption increased with the increasing of sediment mass in solution, while both adsorbed Pb2+ on per unit of sediment and Pb2+ concentration in the solution after equilibrium decreased.

[Heavy metals in environmental media around drinking water conservation area of Shanghai].

The levels of heavy metals in Shanghai drinking water conservation area were determined, and the spatial distributions and main sources of heavy metals were investigated. Moreover, the ecological risk assessment of heavy metals was conducted. Some conclusions can be drawn as follows: (1) The average concentrations of Cd, Hg, Pb, Cu, Zn, Ni, Cr and As in road dust were 0.

[Characteristics of heavy metal pollution in soil and dust of urban parks in Shanghai].

The contents of heavy metals in soils and dust of urban parks in Shanghai were studied, and the spatial distribution of heavy metals was also analyzed. The results showed that the average contents of Pb (55.06 mg x kg(-1)), Zn(198.
