The selective hydrogenation of propyne to propylene has attracted great attention in chemical industry for removing trace amount of propyne for producing polymer-grade propylene. As the state-of-the-art catalyst, Pd suffers from the disadvantage of poor propylene selectivity due to the over-hydrogenation of propylene to propane. We here demonstrate that Pd nanocubes (NCs) coated by zeolitic imidazolate frameworks (i.e., Pd NCs@ZIF-8) can serve as highly active and selective catalysts for propyne selective hydrogenation (PSH). Benefitting from the unique properties and abundant groups of ZIF-8, Pd carbide (Pd-C) is formed on the surface of Pd NCs after thermal treatment, which acts the active sites for PSH to propylene. More importantly, the content of Pd-C can be precisely controlled by altering the calcination temperature without aggregation of Pd NCs and obvious changes in the framework of ZIF-8. The formation of Pd-C on Pd NCs@ZIF-8 can strongly suppress the H2 adsorption, and thus selectively catalyze propyne to propylene. Consequently, the optimized catalyst (i.e., Pd NCs@ZIF-8-100) exhibits a propylene selectivity of 96.4% at a propyne conversion of 93.3% at 35 °C and atmospheric pressure. This work may not only provide an efficient catalyst for PSH, but also shed a new light on the catalytic application of ZIFs.

Objective：Transcatheter arterial chemoembolization （TACE） is a standard treatment for hepatocellular carcinoma （HCC） and/or some unresectable liver metastasis *** liver metastatic lesions such as metastasis from gastrointestinal stromal tumor （GIST） are an indication for transcatheter arterial embolization （TAE）.The purpose of this study was to evaluate the efficacy and safety of Embosphere（㊣）-TAE （Embo-TAE） in comparison with conventional TACE （cTACE） for the treatment of liver metastasis from ***：A total of 45 patients who underwent TACE between Aug 2008 and Feb 2013 were *** with GIST who underwent TAE with Embosphere（㊣）（n=19） were compared with controls who received cTACE （n=26）.The primary end points were treatment response and treatment-related adverse *** secondary end points were progression-free survival （PFS） and overall survival （OS）.Results：The treatment response of Embo-TAE group was significandy higher than that of the cTACE group （P＜0.001）.The PFS was significandy better in the Embosphere（㊣）-group than in the cTACE group （56.6 and 42.1 weeks,respectively; P=0.003）.However,there was no statistically significant difference in liver toxicity between the two groups （P＞0.05）.The median OS in the Embo-TAE group was longer than that in the cTACE group （74.0 weeks,95％ CI：68.2-79.8 vs.61.7 weeks,95％ CI：56.2-67.2 weeks）（unadjusted P=0.045）.The use of Embo-TAE significantly reduced the risk of death in patients with GIST with liver metastases according to the Cox proportonal hazards regression model [hazard ratio （HR）：0.149; 95％ CI：0.064-0.475].Conclusions：TAE with Embosphcre（㊣） showed better treatment response and delayed tumor progression compared with *** was no significant difference in treatment-related hepatic *** thus appears to be a feasible and promising approach in the treatment of liver metastasis from GIST.

Histone H3 lysine 27 trimethylation(H3K27me3) is a histone modification associated with transcriptional repression. However, insights into the genome-wide pattern of H3K27me3 in grapevines are limited. Here, anti-H3K27 chromatin immunoprecipitation(ChIP), high-throughput sequencing, and transcriptome analysis were performed using leaves of Vitis amurensis. The leaves were treated at 4°C for 2 h and 24 h and used to investigate changes in H3K27me3 under chilling treatment. The results show that H3K27me3 is well-distributed both in gene regions(-50%) and in the intergenic region(-50%) in the grapevine genome(Vitis vinifera ‘Pinot Noir PN40024'). H3K27me3 was found to be localized in8 368 annotated gene regions in all detected samples(leaves at normal temperature and under chilling treatments) and mainly enriched in gene bodies with the adjacent promoter and downstream areas. The short-term chilling treatments(4°C for 2 h) induced 2 793 gains and 305losses in H3K27me3 modification. Subsequently, 97.3% of the alterations were restored to original levels after 24 h treatment. The ChIP-qPCR for five differential peaks showed similar results to the data for ChIP-seq, indicating that the chilling-induced H3K27me3 modification is *** analysis of transcriptome and ChIP-seq results showed that the expression of H3K27me3 target genes was significantly lower than those of non-target genes, indicating transcriptional repression of H3K27me3 in grapevine leaves. Furthermore, histone methylation alterations were detected in 82 genes and were related to either repression or activation of their expression during chilling stress. The findings provide the genome-wide H3K27me3 patterns in grapevines and shed light on uncovering its regulation in chilling stress responses.
