RESUMO
Whole visible range emitting CuInS2/ZnS QDs were obtained with broad band-width and high luminous efficiency by altering the Cu/In ratio and coating ZnS layer. 1-Dodecanethiol (DDT) as a sulfur source in the ZnS coating process can inhibit the lattice defects caused by Zn2+ inter-diffusion, thus increasing the photoluminescence quantum yield (PL QY). Then the stability and lighting performance of white light-emitting diodes (WLEDs) based on these CuInS2/ZnS QDs were characterized. The optimized WLED device exhibited a moderate luminous efficacy (LE) (70.33 lm·W-1) and ultrahigh color qualities (CRI Ra = 92.7, R9 = 95.9, R13 = 96.3) with warm white at a correlated color temperature (CCT) of 4052â K.
RESUMO
Objective Observe the effect of Total paeony glycoside(TPG)has on the T-cell immune action and apoptosis process of Oral lichen planus patients and analyze the mechanism.Methods 20 OLP patients are recruited into this experiment, each is treated with TPG,and their clinical effect is taken notes of.Observe the apoptosis of OLP lesions from each of the patients before and after the treatment,compare the apoptosis condition and the expression of CD4 + ,CD8 + ,and the CD4 +/CD8 + ratio,to analyze the role TPG plays on the immune expression of T-cell and the effect on apoptosis process.Results TPG improve the clini-cal manifestation of OLP patients significantly,resulting in the decrease of reticulum and erosive areas,and the pain index is de-creased obviously.The expression of CD4 + and CD8 + are decreased in OLP lesions after the treatment of TPG.Conclusion TPG may induce the apoptosis of the T-cell in lamina propria of the OLP lesions to regulate the T-cell immune action of OLP patients, and slow the development of inflammatory process of OLP,and in that way,TPG shows its potential in treating OLP,and this ex-periment can provide the primary evidence.
