Cardiovascular and cerebrovascular diseases（CCVDs）, which are circulatory system diseases caused by heart defects and vascular diseases, are the major noncommunicable diseases affecting global public health. With the improvement of economic level and the change of human lifestyle, the prevalence of CCVDs continues to increase. Ginseng（Panax ginseng C. A. Mey.） was widely used in traditional diseases due to its supposed tonic properties. Ginsenoside Rb1（G-Rb1） is the most abundant active ingredient with multiple pharmacological effects extracted from ginseng, which has been shown to have potential benefits on the cardiovascular system through a variety of mechanisms, including anti-oxidation, antiinflammatory, regulation of vasodilation, reduction of platelet adhesion, influence of calcium ion channels, improvement of lipid distribution, involving in glucose metabolism and controlling blood *** review reviewed the protective effects of G-Rb1on CCVDs and its potential mechanisms, such as atherosclerosis（AS）, hypertension, coronary heart disease（CHD）, ischemic stroke（IS） and periocular microvascular retinopathy. Finally, we reviewed and reported the results of in vivo and in vitro experiments using G-Rb1to improve CCVDs, highlighted its efficacy, safety, and limitations.

The present paper reports new results regarding the addition of pseudo-boehmite as a binder during the synthesis of shaped Pt/WO_(3)-ZrO_(2)-Al_(2)O_(3) (PtWZA) catalysts. Binder shaping can noticeably influence not only the structure and acidity of catalyst and improve its catalytic performance with regard to n-heptane isomerization, but the mechanical strength of the catalyst. A suitable binder content can improve the isomerization activity or selectivity by changing the acidity of PtWZA. The influence of the binder content depends on the WO_(3) content of the catalyst. PtWZA catalysts that contain 5%-15% binder on a dry basis exhibit favorable isomerization performance that depends on WO_(3) content. Suitable catalysts include Pt20WZ5A and Pt30WZ15A, which provide conversions of approximately 80%-90% and a selectivity of 90%. These new findings enrich researcher knowledge of the effect of the binder on the catalyst shaping process and are useful in the production of industrial catalysts.

在全球水资源日益缺乏的情景下,伴随城市化过程出现的生活污水量显著增加,如何有效利用这一资源成为社会、经济可持续发展的关键。以珍贵树种毛红椿为材料,在遮雨棚下系统研究了生活污水、生活污水与自来水的混合水(以下简称"混合水")以及自来水为灌溉水质,对毛红椿播种苗生长、育苗基质的性质及其中主要重金属含量的影响,以探讨生活污水应用于育苗生产的可能性。结果表明:(1)生活污水与混合水灌溉后均促进了毛红椿苗高、地径的生长,苗高分别为自来水的213.1%、210.4%,地径分别为163.9%、155.5%,生物量的增加也非常明显,特别是地上部分生物量,不同水质间苗高、地径、生物量均达到显著性差异。(2)生活污水灌溉改善了栽培基质的pH、容重等性质,但重金属含量也出现增加的趋势,不过均低于《土壤环境质量标准》(GB15618—1995)中二级标准限值,同时毛红椿各器官中重金属含量也升高。不同重金属在不同器官中的富集程度不同,Cu、Zn、As、Mn在叶中富集较明显,Cr、Pb没有出现富集现象。因此,生活污水及混合水可应用于毛红椿苗木培育。

采用等体积浸渍法制备了PSZA(Pt/SO_(4)^(2-)/ZrO_(2)-Al_(2)O_(3))固体超强酸催化剂,在微型固定床反应器上评价了其催化轻烃异构化性能,考察了含不同杂质的n-C_(5)(正戊烷)、n-C_(6)(正己烷)原料在PSZA上的异构化性能。实验结果显示:n-C_(5)与n-C_(6)混合原料的比例基本不影响其各自转化率,与单一组分的转化率相当。原料中异构烷烃i-C_(5)(异戊烷)和i-C_(6)(异己烷)比例越多时,n-C_(5)和n-C_(6)转化率越低,产物组成接近n-C_(5)和n-C_(6)单独转化。甲基环戊烷、苯等杂质会降低PSZA催化n-C_(5)和n-C_(6)的异构化活性,提高反应温度至180℃可以增加PSZA的异构化活性;n-C_(7)(正庚烷)在PSZA上全部裂解,对PSZA催化n-C_(5)和n-C_(6)活性无显著影响。
