Organic solar cells(OSCs)have achieved rapid advance due to the continuous development of high-performance key ***,the power conversion efficiencies(PCEs)of OSCs under 1 Sun condition(AM 1.5 G,100 mW/cm2)are striving toward 19%[1−5].The PCE improvement benefits from the largely enhanced short-circuit current density(Jsc)and fill factor(FF).However,these cells show relatively low open-circuit voltage(Voc)around 0.8-0.9 V.

Objective: To evaluate the systemic inflammatory and stress response in patients with COPD complicated by pulmonary infection after bronchoalveolar lavage with ambroxol hydrochloride. Methods: A total of 78 patients with COPD complicated by acute pulmonary infection who were treated in the hospital between October 2015 and January 2017 were collected as research subjects and divided into control group (n=39) and study group (n=39) by random number table. Control group received routine treatment, and study group received the routine + bronchoalveolar lavage with ambroxol hydrochloride. The differences in serum levels of inflammatory factors and oxidative stress indexes were compared between the two groups before treatment and after 1 week of treatment. Results: There was no statistically significant difference in serum levels of inflammatory factors and oxidative stress indexes between the two groups before treatment. After 1 week of treatment, serum inflammatory factors IL-2, IL-6, IL-8, TNF- , CRP and PCT levels of study group were lower than those of control group;serum oxidation indexes MDA, MPO and AOPPs levels were lower than those of control group while anti-oxidation indexes SOD, T-AOC and GSH-Px levels were higher than those of control group. Conclusion: Bronchoalveolar lavage with ambroxol hydrochloride can significantly inhibit the systemic inflammatory and oxidative stress response and help control the disease in patients with COPD complicated by pulmonary infection.

Remarkable progress has been made in conjugated copoly-mer donors due to the development of novel fused-ring ac-ceptor(FRA)building units[1−15].The copolymers based on FRA units have delivered excellent power conversion efficien-cies(PCEs)up to 18.69%in organic solar cells(OSCs)[16].Fused-ring aromatic lactones are promising FRA units[17−19].

Background:Genome-wide analysis of gene-gene interactions has been recognized as a powerful and reasonable way to identify the missing heritability underlying complex disease that are undetectable in current single-point association ***,several data mining methods of model free in nature for detecting non-linear dependence between genetic loci have been developed,but most of them suffer from the risk of inflated false positive error(type 1 error) rate in testing the interaction hypothesis,which is particularly salient when the main effects at one or both loci are large. Methods:In this report,we propose to use two conditional entropy-based metrics to control this inflated false positive error rate,induced by the large main effects at the loci. We elucidate the mathematical relationship between the conditional mutual information and interaction metric in the context of relative ***,we evaluate the performance of these metrics for identifying interaction effects under different disease models,through extensive simulations and real data applications. Results:Our results demonstrate that unconditional mutual information,although more powerful in detecting interactions,is very sensitive to main effects,particularly in additive interaction *** comparison,the conditional mutual information metrics based on either genotype or haplotype can maintain the controlled false positive error rate without substantial loss of power for detecting gene-gene interactions in a wide range of disease models. Conclusions:In conclusion,we recommend to use the conventional unconditioned data mining metrics to identify "joint effect" of two genetic loci,followed by the use of conditional mutual information for purpose of detecting genuine "interaction effect",in the genome-wide interaction assay.

The effect of rotary electromagnetic stirring(EMS)on the Cu grain size and Fe dendrites is investigated in this paper,in order to get a Cu-Fe alloy ingot with good *** macro-and micro-structures are observed by Leica-DMR optical *** solidification structures of Cu-2 and 8wt.%Fe consist with finer equiaxed grains. The Cu grain size is most sensitive to the Fe *** can't effectively improve the grain size for the Cu-Fe alloy. For ingot cooled without EMS,there are also many large Fe-rich particles distribute in the Cu-matrix,beside the Fe dendrites,because of the existence of metastable miscibility gap in the undercooled liquid *** the Fe-rich phases are not found in the ingots with EMS,indicating the EMS can affect the undercooling of the liquid and further restrain the liquid phase *** the EMS,the Fe dendrites break up into many smaller Fe *** the size of Fe fragments decreases with the increasing stirring current.
