Water pollution is a serious problem around the world. It causes the lack of clean drinking water and brings risks to human *** technology has become a competitive candidate to treat the contaminated wastewater due to its high separation efficiency and low energy consumption. In this review, we introduce the recent development of several kinds of bioinspired separation membranes, involving the membrane design and applications. We emphasize the multi-phase liquid separation membranes inspired from nature with special wettability applied for oil/water separation, organic liquids mixture separation, and emulsion separation. After separating multi-phase liquids using these membranes, small molecule pollutants still exist in singlephase liquid. Therefore, we also expand the scope to small molecule-scale separation membranes, such as the nacre-like graphene oxide separation membrane and other nanofiltration membranes. Summary and outlook concerning the future development of separation membranes are also introduced briefly.

Chronic lymphocytic leukaemia （CLL） is a rare blood cancer that always relapses as refractory disease and eventually leads to death. To date, therapeutic options for CLL patients are scarce and there is an urgent need to develop novel chemotherapeutics that are both effective and safe. Gold-containing compounds induce a lethal oxidative and endoplasmic reticulum stress response in cultured and primary CLL cells via inhibition of thioredoxin reductase （TrxR）. However, traditional gold-containing medicines have revealed side effects during clinical applications. Therefore, safer gold-containing drugs are needed to overcome this challenge. In this study, a novel peptide templated gold cluster Au2sSv9 was synthesized and its therapeutic effect on CLL cells was evaluated. This nanocluster could induce cell apoptosis in MEC-1 cells in a dose-dependent manner which correlated with the uptake amount of clusters in cells. As expected, increasing intracellular reactive oxidative species （ROS） in MEC-1 cells was exhibited with the increase of cluster dosage. Further analyses demonstrated the underlying mechanism that the nan- oclusters suppress the activity ofTrxR1, increase the level of intracellular ROS, destroy the mitochondrial membrane potential and finally trigger the mitochondrial apoptotic pathway in MEC-1 cells. Furthermore, the direct interaction between Au2sSv9 clusters and TrxRl was confirmed for the first time by isothermal titration calorimetry. These findings explored the preclinical efficacy and potential mech- anism of gold clusters in CLL therapy and provided a fundamental reference for the development of other novel gold-containing chemotherapeutics to treat CLL.

Prognostic Value of NT-proBNP in Stable Coronary Artery Disease in Chinese Patients after Percutaneous Coronary Intervention in the Drug-eluting Stent Era

引用

Biomedical and Environmental Sciences 2018年第12期31卷 859-866页

作者： zhao Xue Yan li Jian Xin TANG Xiao fang XU Jing Jing SONG ying JIANG lin CHEN Jue SONG Lei gao li Jian gao Zhan QIAO Shu Bin yang Yue Jin gao Run lin XU Bo yuan Jin Qing State Key Laboratory of Cardiovascular Disease Fuwai Hospital National Center for Cardiovascular Diseases Chinese Academy of Medical Sciences and Peking Union Medical College

Objective The predictive value of N-terminal pro-brain natriuretic peptide(NT-proBNP) in patients with stable coronary artery disease(SCAD) in the drug-eluting stent era is not yet clear. We aimed to evaluate the prognostic value of NT-proBNP in SCAD patients after percutaneous coronary intervention(PCI). Methods We examined 4,293 consecutive SCAD patients who underwent PCI between January 2013 and December 2013 in Fuwai Hospital, China. The primary endpoint was all-cause death. NT-proBNP levels were measured before PCI using Elisa kits(Biomedica, Austria). The indication for PCI was based on the degree of coronary stenosis and evidence of ischemia. Results Among 3,187 SCAD patients with NT-proBNP data, after a 2-year follow-up, NT-proBNP levels were predictive for all-cause death in the SCAD population [area under the receiver operating characteristic curve, 0.768; 95% confidence interval(CI), 0.687-0.849; P < 0.001]. At the optimum cutoff point of 732 pg/mL, the sensitivity and specificity of death was 75.0% and 72.3%, respectively. In a multivariable Cox regression model, the death hazard ratio was 6.43(95% CI, 2.99-13.82; P < 0.001) for patients with NT-proBNP levels ≥ 732 pg/mL, compared with < 732 pg/mL. Conclusion NT-proBNP is a strong predictor of 2-year death with SCAD after PCI in the drug-eluting stent era.
