Through the analysis of the surrounding rock, coal seam burial depth, coal quality and hydrologic geological condition, the methane-bearing property characteristics of the coal reservoir in the Gemudi syncline were elucidated. Most of the wall rock of the coal reservoir is mudstone and silt, which is a favourable enclosing terrane. Burial depth of the main excavating coat seam is moderate. The groundwater activity is thin, and there are absolute groundwater systems between each coal seam, which make poor intercon- nections to accelerate CBM enrichment. In our research, the area coal reservoir meta- morphosis is high, CBM content is high, hole-cranny system development degree is high, and permeability of the great mass of the main coal seam exceeds 0.1×10^-3 μm2, The result demonstrates that the southeast of the Gemudi syncline has the best conditions for prospecting and exploiting CBM.

化学制浆法是造纸行业中广泛采用的纸浆制造工艺,其中的漂白工序传统上普遍使用元素氯进行漂白,并利用所生成的氯气作为漂白剂,这种漂白方式会产生大量有毒性的有机卤化物,包括强致癌物二噁英等。鉴于次,近年来用二氧化氯为漂白剂的无元素氯漂白工艺开始被大量引入造纸行业,作为漂白工序的替代技术。通过研究无元素氯漂白工艺各个工段的工艺特点,归纳出无元素氯漂白纸浆在技术及环境成本综合考虑基础上的合理性,从而为其作为未来一段时期内造纸企业特别是中小型企业,为符合最新产业政策和环保标准,而对传统元素氯漂白工艺进行淘汰升级的工艺路线提供科学的参考。

Graphene/Ag nanoparticles (GAg) were fabricated via a facile method, employing graphite oxide as a precursor of graphene sheet (GNS), AgNO3 as a precursor of Ag nanoparticles, and sodium citrate as a reducing and stabilizing agent. We synthesized three kinds of GAg as GAg-1, GAg-2 and GAg-3. We introduced high electron mobility GAg into the active layer of polymer solar cell. The cell structure was ITO/PEDOT:PSS/P3HT:PCBM:GAg/Ca/Al. The weight ratio of P3HT:PCBM:GAg of active layer is 1:1:0.01. We study the effect of GAg addition on the photovoltaic performance. We use the UV-Vis, SPM, FE-SEM and solar simulator to measure the absorbance, roughness, surface morphology, and power conversion efficiency (PCE), respectively. From these results, we found that the fill factor (FF) and PCE of the cells with GNS or GAg are always higher than those of cell without GNS or GAg. The cell with GAg-2 had the highest short circuit current density (Jsc) of 8.56 mA/cm2, an increase of 20.2%, the highest fill factor (FF) of 0.56, an increase of 14.3% and the highest PCE of 2.78%. This is a 24.7% increase in efficiency compared to the cell without GNS or GAg. These improvements were due to the high carrier mobility of grapheme.

目的探究乙型肝炎患者不同阶段的外周血单个核细胞(PBMC)表面程序性死亡受体-1(PD-1)、半胱氨酸天冬氨酸酶-9(Caspase-9)水平,寻找其临床表达意义。方法选取湘潭市中心医院感染性疾病与肝病科2020年3月至2022年9月进行治疗的224例乙型肝炎患者,根据其病情阶段将所有患者分成乙型肝炎轻度组(n=83)、乙型肝炎中度组(n=76)和乙型肝炎重度组(n=65)。另取同期肝癌患者21例作为肝癌组,同期健康体检人员70例归入健康组。比较各组乙型肝炎患者肝功能指标,PBMC表面PD-1、Caspase-9水平,统计分析不同病情阶段与PBMC表面PD-1、Caspase-9水平的关系以及其对于病情阶段的预测价值。结果乙型肝炎轻度组、乙型肝炎中度组、乙型肝炎重度组患者以及肝癌患者的谷草转氨酶(AST)、谷丙转氨酶(ALT)、乙型肝炎DNA(HBV-DNA)都显著高于健康组,乙型肝炎轻度组、乙型肝炎中度组、乙型肝炎重度组和肝癌组AST、ALT依次升高,并且各组之间差异有统计学意义(P0.05)。PBMC表面PD-1与AST、ALT呈正相关,与HBV-DNA呈负相关,而Caspase-9水平与AST、ALT呈负相关,与HBV-DNA呈正相关,PBMC表面PD-1、Caspase-9水平联合检测重度乙型肝炎发展为肝癌的AUC值为0.911,敏感度为90.31%,特异度为89.63%。结论乙型肝炎患者不同阶段的PBMC表面PD-1、Caspase-9水平有显著差异,且两者表达水平与肝功能指标存在相关性,进行PD-1、Caspase-9的联合检测可以对重度乙型肝炎发展为肝癌进行预测。

Emerging evidence has indicated that BRCC36-mediated K63-linked ubiquitination modification was involved in diverse cellular functions,including endocytosis,apoptosis and DNA damage repair. We previously showed that activation of c GMP / PKG pathway contributed to the binding of BRCC36 and the pro-fibrotic factor Smad3. The current study tested the hypothesis that BRCC36 functions as a negative regulator of transforming growth factor-beta( TGF-β) / Smad3 pathway and participates in cardiac remodeling. In isolated adult mouse cardiac fibroblasts,we have demonstrated that TGF-β1 treatment significantly increased the expression of BRCC36. Overexpression BRCC36 suppressed TGF-β1-induced Smad3 phosphorylation,nuclear translocation,extracellular matrix molecular expression and cell proliferation. On the contrary,silencing BRCC36 by transfection of adenovirus-carrying BRCC36 sh RNA potentiated to enhance the pro-fibrotic effect of TGF-β. In vivo,under chronic pressure overload condition-induced by transverse aortic constriction,myocardial pro-survival protein Bcl-2 and Mcl-1 expression were significantly decreased and the pro-apoptosis protein Puma was increased. However,the cardiac-specific over-expression of BRCC36 significantly increased myocardial Bcl-2 and Mcl-1 and inhibited Puma expression. Interestingly,we also found that sustained pressure overload resulted in a significant myocardial DNA injury in wild type mice,which was characterized by the increase of γH2AX level. However,cardiac-specific BRCC36 over-expression significantly decreased the level of γH2AX in the pressure overloaded heart in the transgenic mice,while effectively enhanced myocardial RAD51 expression,a marker of DNA damage repair. Furthermore,BRCC36 over-expression effectively attenuated TAC-induced cardiac fibrosis and remodeling in the transgenic mice,compared with the wild type mice. Collectively,the results have suggested that BRCC36 effectively protected heart against chronic pressure overload
