There exist a number of mercury-resistant bacterial in environment, Mer operon is involved in the resistant mechanism, MerRTPA of Mer operon encodes the proteins related to the regulation, transport and reduction of mercury ion, respectively. The toxic mercury ion is transported by MerTP from medium to cytoplasmic mercuric reductase, MerA, and deoxidized to non-toxic and volatile element mercury, Hg(0). Bacterial mercury-resistant system originated from ancient times, and evolved into the Mer operon with diversity by gene integration and insertion. Mercury-resistant bacteria highly specifically absorb mercury ion, and can be used in recovering the mercury-polluted environment as well as the genetic selective marker.

The contamination of extrinsic harmful contaminants including mycotoxins, heavy metals and pesticides, etc, brings serious risks to traditional Chinese medicines (TCMs), further to human health. Due to their unique photoluminescence, chemiluminescence, electrochemical and electrochemiluminescence properties, semiconductor quantum dots (QDs) nanoparticles are widely used to immobilize bioprobes and biosensors, etc. In this review, the luminescence characteristics and specific ligands of QDs probles which are used to determine contaminants were summed up. Then, the applications of QDs-coated novel probes in the determination of mycotoxins, heavy metals and pesticides were discussed in detail. In addition, the contamination levels and characteristics of extrinsic harmful residues in TCMs were investigated. Further, the maximum levels of those contaminants in TCMs were compared with those set by various countries. Finally, the future development trends and problems of QDs-coated probes in the determination of those extrinsic residues in TCMs were prospected.

In this study, the human umbilical vein endothelial cell model was used to study the regulating effect of lipophilic components in Salvia miltiorrhiza on angiogenesis, and explore its possible mechanism. The cell model was established to determine the effect of lipophilic components in S. miltiorrhiza on the proliferative activity and migration capacity of endothelial cells. Then the realtime fluorescence quantification PCR technology was applied to detect the changes in the gene expressions of angiogenesis-related cytokines VEGF-A, VEGF-C and MMP-9. The results showed that 5 mg x L(-1) lipophilic components in S. miltiorrhiza could inhibit the proliferation and migration of endothelial cells, and reduce the expression of VEGF-A and MMP-9 genes. It indicated that lipophilic components in S. miltiorrhiza may inhibit the proliferation and migration of endothelial cells by inhibiting the expression of VEGF-A and MMP-9 genes, so as to show the inhibitory effect on angiogenesis.
