The co-contamination of metals and organic pollutants,such as Pb and methyl tert-butyl ether(MTBE),in groundwater,has become a common and major phenomenon in many contaminated *** study evaluated the feasibility of their simultaneous removal with permeable reactive barrier(PRB)packed with mixed zeolites(clinoptilolite and ZSM-5)using fixed-bed column tests and breakthrough curve *** effect of grain size on the permeability of PRB and removal efficacy was also assessed by granular and power *** replacement of granular clinoptilolite by powder clinoptilolite largely reduced the breakthrough time but increased the saturation time nearly *** column adsorption capacity of clinoptilolite powders almost tripled that of clinoptilolite granules(130.6mg/g versus 45.3 mg/g)due to higher specific surface *** minimum thickness and corresponding longevity of PRB were calculated as 7.12 cm and 321.5 min when 5%of granular clinoptilolite was mixed with 5%ZSM-5 and 90%sand as mixed PRB reactive media compared with 10.86 cm and 1230.2 min for the application of powder *** study is expected to provide theoretical support and guidance for the practical application of mixed adsorbents in PRBs.

护肝布祖热颗粒是维吾尔族传统的护肝方。作者在先前的一项研究中通过调节免疫平衡和抑制IRF1/JNK信号诱导的细胞凋亡,探讨了HBG抗免疫性肝损伤(ILI)的机制。但不是所有的机制都得到了探讨。本研究通过体内实验及网络药理学进一步研究了HBG降低小鼠刀豆球蛋白A(ConA)诱导的ILI的机制。首先,TCMSP、PharmMapper和GeneCards数据库确定了HBG治疗ILI的活性化合物和关键靶点。通过网络药理学和分子对接对确定的关键靶点和相关信号通路进行筛选。ConA诱导的小鼠ILI模型探讨了HBG对抗ILI的疗效和机制;蛋白质印迹分析检测关键蛋白的表达水平;网络药理学鉴定了16个化合物和53个靶标。成分-靶向通路(C-T-P)网络和分子对接表明,EGFR、HRAS、AKT1和PIK3R1是HBG对抗ILI的关键靶点。此外,分子对接显示,前八种活性化合物的对接得分高于阈值。与ConA组相比,HBG显著上调p-EGFR、Ras、p-AKT、p-PI3K、p-BAD和Bcl-2的表达,并下调Bax、裂解caspase 9和3的蛋白水平。HBG通过EGFR/Ras/PI3K/AKT信号通路抑制细胞凋亡,从而减轻ILI。

雨水管网是缓解城市内涝、改善水环境质量的重要市政基础设施,受管材老化腐蚀和施工过程不当等影响,我国城市雨水管网建成后普遍存在地下水入渗和污水混接问题,制约着雨水管网功能高效发挥。排水管网入流入渗诊断技术可为雨水管网混接入渗问题的识别和定位提供支持。综述了排水管网入流入渗诊断技术(物探检测技术、流量分析技术、特征因子分析技术、水动力反演模型技术)的基本原理、研究进展、应用特征等,对比分析了不同技术应用于雨水管网混接入渗诊断的适用性、实施要点、诊断水平和发展阶段等,并提出未来雨水管网混接入渗诊断技术的发展方向。结果表明:1)特征因子分析技术可在不干扰雨水管网正常运行条件下识别和量化混接入渗问题、提供治理优先级,因此经济和环境效益显著;2)光纤分布式测温(FDTS)技术和水动力模型反演技术在无干扰定位雨水管网混接入渗方面优势显著,前者易于实施且定位精准度高,后者具有成本低且可评级混接入渗等级特点,可根据场景特征因地制宜选用;3)未来雨水管网混接入渗诊断技术将朝着低成本、无干扰、可量化、可定位的方向发展。通过评估不同技术在当前和未来的综合应用效果,明确了单一诊断技术难以具备未来预期特征,而特征因子分析技术耦合FDTS技术或水动力模型反演技术的分级诊断体系具有实现未来技术发展目标的优势潜力。研究可为雨水管网混接入渗诊断技术的科学应用和优化创新提供参考。

Water quality restoration in rivers requires identification of the locations and discharges of pollution sources,and a reliable mathematical model to accomplish this identification is *** this paper,an innovative framework is presented to inversely estimate pollution sources for both accident preparedness and normal management of the allowable pollutant *** proposed model integrates the concepts of the hydrodynamic diffusion wave equation and an improved Bayesian-Markov chain Monte Carlo method(MCMC).The methodological framework is tested using a designed case of a sudden wastewater spill incident(i.e.,source location,flow rate,and starting and ending times of the discharge)and a real case of multiple sewage inputs into a river(i.e.,locations and daily flows of sewage sources).The proposed modeling based on the improved Bayesian-MCMC method can effectively solve high-dimensional search and optimization problems according to known river water levels at pre-set monitoring *** can adequately provide accurate source estimation parameters using only one simulation through exploration of the full parameter *** comparison,the inverse models based on the popular random walk Metropolis(RWM)algorithm and microbial genetic algorithm(MGA)do not produce reliable estimates for the two scenarios even after multiple simulation runs,and they fall into locally optimal *** much more water level data are available than water quality data,the proposed approach also provides a cost-effective solution for identifying pollution sources in rivers with the support of high-frequency water level data,especially for rivers receiving significant sewage discharges.
