15# nanosilvehas significantly bateriostatic effect against Penicillium, The minimal inhibitory concentrations of 15# nana silve for inhabiting Penicillium is 1 mg/L. Through a comparative study of the bacteriostatic effect of different nanosilver and other bacteriostatic agents against Penicillium, it is found that the bacteriostatic effect of nanosilver against penicillium is very significantly better than lincomycin hydrochloride and streptomycin sulfate, in which, the bacteriostatic effect of nanosilver 14# nanosilve against penicillium is significantly better than 13# nanosilve, and 13# nanosilve is very significantly better than that of 15# nanosilve.It provides a new way for the prevention and control of Penicillium.

Through a comparative study of the bacteriostatic effect of nanosilver of different species and concentrations against bacteria, it is found that nanosilver have significant bacteriostatic effect against bacteria. Bateriostatic effect of nanosilve 15# against B. thuringiensis is significantly better than E.coli, s. aureus and B. subtillis. The optimal concentrations of 15# for inhabiting E. coli, S. aureus, B. subtillis and B. thuringiensis respectively are: 20 mg/L, 10 mg/L, 1 mg/L, 40 mg/L. nanosilvers of 13#, 14# and 15# have no significant differences in the bacteriostatic effect against E.coli, but are all significantly better than the bacteriostats of lincomycin hydrochloride and streptomycin sulfate. Antibacterial principle of nanosilver is damaging the cell membrane permeability.

AbstractWhether companies and shareholders should be held liable for land contamination that occurred prior to the passage of the law imposing liability for such contamination is a complex issue. After a theoretical analysis of the legitimacy of retroactivity in land contamination law, our comparative study shows that most countries have adopted, or tacitly approve of, retroactive liability for land contamination. However, the liability schemes implemented in the countries investigated vary as to the types of obligation, the timing of conduct for which liability is imposed, and the standard of liability, among other factors. The retroactive imposition of liability in China's recently enacted Law on the Prevention and Control of Soil Pollution is examined, as well as the roadblocks that still remain, and further improvement based on the theoretical and comparative analysis are considered.

SUMMARY OBJECTIVE To explore the feasibility of health competence cultivation on the prevention and control of Inadvertent Perioperative Hypothermia (IPH). METHODS Patients with expected spinal surgery were divided into group A and group B by the random number method. Group B followed routine IPH management, and health training measures for performance and ability were implemented in Group A. The scores of the health competence questionnaire, the temperature at different times, IPH complications, and hospitalization for the two groups were observed and compared. RESULTS The main evaluation indexes, such as the health competence questionnaire score, temperature fluctuations, and IPH complications, during the perioperative period in group A were significantly better than those in group B (p < 0.05). The indexes of anesthesia, total hospital expenses, and health service satisfaction in group A were also significantly better than those in group B, which shows the advantages of cultivating health capabilities in both doctors and patients. CONCLUSION Through health competence cultivation and feasible health management measures, the medical staff can improve the quality of IPH prevention and management.

The bacteriostatic effect of nanosilve is researching purposes. Five strains from Aspergillus was used as the experimented materials. The concentration of nanosilver is180 mg / L. 0.3% carbendazim and 0.3% chlorothalonil was used as compering bacteriostatic agents. The results was gained that nanosilve has inhibiting on the growth, spore’s germination, and effecting on bacteriostasis ring and shape of the Aspergillus. The bacteriostasis of nanosilve is very better than blank comparing experimert. For the bacteriostdsis of nanosilve on Aspergillus, there is differentation among strains. The bacteriostdsis of carbendaim is better than chlorothdonil. The batteriostdsis of chlorothdonil is very better than nanosilve. The bacteriostdsis principle is that nanosilve disrupts permeation of cell membrance of Aspergillus.
