Phytoremediation effectiveness and remediation costs are driving factors of this project. Full utilization of plant resources after their being used for phytoremediation is an unsolved problem. GC/MS technique was used to investigate the volatiles of the flowers from Elsholtzia argyi (PFE1: Purple Flower Elsholtzia) and their variation (WFE: White Flower Elsholtzia), naturally growing in Pb/Zn mined area, and Elsholtzia argyi (PFE2: Purple Flower Elsholtzia), naturally growing in Jiuxi uncontaminated agriculture soil. Seventeen compounds constituting 86.88% of total essential oils were identified in PFE1, with 2,6-octadienoic acid,3,7-dimethyl-methyl ester being the main constituent (63.30%). Sixteen compounds accounting for 95.32% of total essential oils were identified in WFE, with caryophyllene being the main component (55.02%). Compared to PFE1, PFE2 contains lower level of 2,6-octadienoic acid,3,7-dimethyl-methyl ester (31.76%), which is the main constituent in the total essential oils of PFE2. Caryophyllene is the main ingredient of flavor. Elsholtzia ketone was identified in all the three Elsholtzia plants. It can be concluded that the selected Elsholtzia argyi plants can be exploited on their versatile uses as fragrances and antiseptics due to the perfume ingredient and antibacterial components existing in their essential oils.

Background Postoperative endophthalmitis following intraocular lens(IOL)implantation is still one of the most feared complications of cataract surgery.Bacterial adhesion to IOLs during their insertion is a prominent etiological factor.The adhesion characteristics of bacteria to IOL are very vital for the prevention of endophthalmitis after cataract surgery.Objective The present study was to observe the in vitro adherence ability of Staphylococcus epidermidis to different intraocular lenses(IOLs)and compare the results in bacterial counting between scanning electron microscopy(SEM)photographs and quantitative cultures. Methods Five types of IOLs,including hydrophobic acrylic IOL,polymethylmethaerylate(PMMA)IOL,heparin-surface-modified(HSM) PMMA IOL,silicone(SI)IOL and hydrophilic acrylic IOL,were put into S.epidermidis(ATCC 12228)suspension for 1 hour.The bacterial adhesion numbers on the IOL surfaces were counted by quantitative cultures and scanning electron microscopy(SEM) photographs. Results Quantitative culture counting of viable adherent bacteria released by sonication showed that hydrophobic acrylic IOL and PMMA IOL were more likely for bacteria to attach.The number of bacteria on the five types of IOL surfaces showed significant differences(F=100.084,P=0.000).No significant differences were found in the number of bacteria between hydrophilic acrylic IOL and HSM-PMMA IOL (t=2.285,P=0.052)with the quantitative culture method.Direct counting of adherent bacteria in SEM photographs revealed that there were significant differences in bacterial adhesion numbers among difierent IOL material groups,with the numbers from high to low as follows:Hydrophobic IOL＞PMMA IOL＞SI IOL＞Hydrophilic IOL＞HSM-PMMA IOL(F=118.065,P=0.000).The counting method by SEM method was superior to that by quantitative cultures (t=5.019,P=0.000). Conclusion The bacterial adhesion ability varies upon the difference of IOL materials.Less bacterial adhesion is found on hydrophilic acrylic IOL and HSM-PMMA IOL,implying that the use of IOLs made from these two materials during surgery could diminish the incidence of postoperative endophthalmitis and intraocular inflammation associated with IOLs implantation.

Autophagy is a crucial biological process in eukaryotes, which is involved in cell growth, survival and energy metabolism. It has been confirmed that autophagy mediates toxicity of anticancer drugs, especially in heart, liver and neuron. It is important to understand the function and mechanism of autophagy in anticancer drugs-induced toxicity. Given that autophagy is a double-edged sword in the maintenance of the function of heart, liver and neuron, the autophagy-mediated toxicity are very complicated in the body. We provide a review on the concept of autophagy and current status about autophagy-mediated toxicity of anticancer drugs. The knowledge is crucial in the basic study of anticancer drugs-induced toxicity, and provides some strategies for the development of alleviating the toxicity of anticancer drugs.

A solution with different Cu supply levels was cultured to investigate gama-aminobutyric acid (GABA) accumulation in Elsholtzia splendens, a native Chinese Cu-tolerant and accumulating plant species. Increasing Cu from 0.25 to 500 micromol/L significantly enhanced levels of GABA and histidine (His), but considerably decreased levels of aspartate (Asp) and glutamate (Glu) in the leaves. The leaf Asp level negatively correlated with leaf Cu level, while leaf GABA level positively correlated with leaf Cu level. The leaf Glu level negatively correlated with leaf GABA level in Elsholtzia splendens. The depletion of leaf Glu may be related to the enhanced synthesis of leaf GABA under Cu stress.
