透明质酸（hyaluronic acid, HA）具有良好的生物相容性、生物可降解性和非免疫原性，且对CD44等受体具有主动靶向性。因此，近年来HA已成为设计和制备药物递送载体的重要材料。HA富含可供化学改性的功能团，但不同修饰方法和修饰位点可影响其生物学特性。本文结合HA生物学性质的产生机制、以及其衍生化方法和表征手段深入总结和讨论化学改性对HA生物学性质的影响，为合理的HA化学改性研究提供参考。

为评价农牧交错带典型沙区人地系统可持续性,选择内蒙古乌审旗(毛乌素沙地)、正蓝旗(浑善达克沙地)和奈曼旗(科尔沁沙地)为研究区,构建包括经济发展、社会进步和生态环境3个方面22个具体指标的评价指标体系,并采用全排列多边形综合图示法进行评价。结果表明:1)毛乌素沙地乌审旗人地系统综合可持续性水平最高。2021年乌审旗综合可持续性为Ⅱ级良好水平(0.58),奈曼旗和正蓝旗均为Ⅲ级一般水平(分别为0.31和0.30);2)2015—2021年区域可持续性均表现出增强趋势,乌审旗和正蓝旗提升速度更快。乌审旗同期综合可持续性由Ⅲ级一般水平提升到Ⅱ级良好水平,正蓝旗由Ⅳ级较差水平提升到Ⅲ级一般水平,奈曼旗稳定在Ⅲ级一般水平,综合可持续性指数分别提升了48.72%、47.62%和20%。3)三地区人地系统可持续性改善均是生态环境维度贡献最大。乌审旗、正蓝旗和奈曼旗生态环境指数分别提高58.3%、78.3%和32.4%;社会进步指数提高比例为14.3%~23.1%;经济发展指数仅乌审旗有所提高。综上,沙区人地系统可持续性提升与区域对生态环境保护与治理密切相关,但除乌审旗2018—2021年综合可持续性处于Ⅱ级良好水平外,奈曼旗与正蓝旗2015—2021年、乌审旗2015—2017年综合可持续性都处于Ⅲ级一般水平,农牧交错带沙区可持续发展面临挑战,应针对不同沙区发展特征,有侧重地开展调整与治理。

High salt concentrations can cause plasmolysis and loss of activity of cells, but the salt-torlerant bacterium can endure the high salt concentrations in wastewater. In this research 7 salt-torlerant bacteria, which could survive in dry powder products and could degrade organic contaminants in saline wastewater, were isolated from a membrane bioreactor. The strain NY6 which showed the fastest growth rate, best property for organic matter degradation and could survive in dry powder more than 3 months was selected and characterized. It was classified as Bacillus aerius based on the analysis of the morphological and physiological properties as well as the 16S rRNA sequence and Neigh borjoining tree. The strain NY6 could survive in the salinity up to 6% and the optimal growth salinity is 2%; it belongs to a slightly halophilic bacterium. The capability of its dry powder products for COD removal was 800 mg COD/（***） in synthesized saline wastewater with salinity of 2%. According to salt-tolerant mechanism research, when the salinity was below 2%, the stain NY6 absorbed K~ and Na~ to maintain osmotic equilibrium, and when the salinity was above 2%, the NY6 kept its life by producing a large amount of spores.

Cytosine DNA methylation is an epigenetic modiication in eukaryotes that maintains genome integrity and regulates gene expression. he DNA methylation paterns in plants are more complex than those in animals,and plants and animals have common as well as distinct pathways in regulating DNA methylation. Recent studies involving genetic, molecular, biochemical and genomic approaches have greatly expanded our knowledge of DNA methylation in plants. he roles of many proteins as well as non-coding RNAs in DNA methylation have been uncovered.

探究脆弱区生境质量变化过程及未来情景格局对于研究区生态环境科学保护具有重要意义。本研究基于土地利用数据、FLUS-In VEST模型及空间自相关方法,分析中国北方农牧交错带2000—2020年生境质量时空格局,并对2040年生境质量进行多情景模拟。结果表明:(1)草地是研究区的主要土地类型,占比超过41%。2000—2020年研究区耕地变化最为显著,面积减少10157 km^(2),林地和建设用地面积有所增加。(2)研究区东南边界生境质量相对较高;2000—2020年平均生境质量变化不大,但生境质量较低等级和较高等级的面积分别增加2281 km^(2)和1375 km^(2),退化度较高的研究区则呈现为点状集中分布在部分建设用地上。(3)2040年各情景下生境质量呈现出向好趋势,但生态保护情景下生境质量提升最为显著,较高等级面积较2020年增加2514 km^(2)。建议未来土地利用规划和生态环境保护过程中,需重点关注内蒙古东南部、河北北部等生境质量低的区域。

Fe/Al drinking water treatment residuals（WTRs）, ubiquitous and non-hazardous by-products of drinking water purification, are cost-effective adsorbents for glyphosate. Given that repeated glyphosate applications could significantly decrease glyphosate retention by soils and that the adsorbed glyphosate is potentially mobile, high sorption capacity and stability of glyphosate in agricultural soils are needed to prevent pollution of water by ***, we investigated the feasibility of reusing Fe/Al WTR as a soil amendment to enhance the retention capacity of glyphosate in two agricultural soils. The results of batch experiments showed that the Fe/Al WTR amendment significantly enhanced the glyphosate sorption capacity of both soils（p 〈 0.001）. Up to 30% of the previously adsorbed glyphosate desorbed from the non-amended soils, and the Fe/Al WTR amendment effectively decreased the proportion of glyphosate desorbed. Fractionation analyses further demonstrated that glyphosate adsorbed to non-amended soils was primarily retained in the readily labile fraction（Na HCO3-glyphosate）. The WTR amendment significantly increased the relative proportion of the moderately labile fraction（HCl-glyphosate） and concomitantly reduced that of the Na HCO3-glyphosate, hence reducing the potential for the release of soil-adsorbed glyphosate into the aqueous phase. Furthermore, Fe/Al WTR amendment minimized the inhibitory effect of increasing solution p H on glyphosate sorption by soils and mitigated the effects of increasing solution ionic strength. The present results indicate that Fe/Al WTR is suitable for use as a soil amendment to prevent glyphosate pollution of aquatic ecosystems by enhancing the glyphosate retention capacity in soils.

The assignment of the rovibrational spectra of molecule-Ne complexes is always a challenge to study van der Waals systems, since they usually exhibit behavior intermediate between free rotor and rigid rotor. In this paper, the microwave and infrared spectra of CH3F-Ne, a model system for symmetric-top-atom dimer, were firstly pre- dicted and analyzed based on the four-dimensional ab initio intermolecular potential energy surfaces（PESs）, which explicitly incorporate the v3（C--F） stretch normal model coordinate of the CH3F monomer. Analytic three-dimensional PESs were obtained by least-squares fitting vibrationally averaged interaction energies for v3（CH3F）=0 and 1 to the Morse/long-range（MLR） potential function for symmetry top impurity with atom model. These PESs fitting to 2340 points have root-mean-square（RMS） deviations of 0.07 cm1, and require only 167 parameters. Based on the analytical vibrationally averaged PESs, the rovibrational energy levels were calculated by employing Lanczos algorithm, with combined radial discrete variable representation and parity-adapted angular finite basis representation. Based on the wavefunction analysis and comparison of CH3F-Ne with CH3F-He and CH3F-Ar complexes, the bound states were assigned. Spectral parameters for CH3F-Rg（Rg： rare gas, Rg=He, Ne, Ar） complexes were fitted and discussed. Temperature dependent transition intensities for CH3F-Ne were also reported and analyzed. The complete microwave and infrared spectra information for CH3F-Ne made it possible to provide important guidance for future experimental spectroscopic assignments.
