引用

World Journal of Gastroenterology 2017年第23期23卷 4233-4242页

作者： shan zhuang yong-mei jian yong-ning sun department of traditional chinese medicine shanghai jiao tong university affiliated sixth people's hospital

AIM To investigate the inhibitory effect of Liuwei Dihuang Pill(LDP) on gastric tumorigenesis induced by N-methyl-N-nitrosourea(MNU) in diabetic *** Four-week-old mice were divided into four groups: A, 12 db/m mice treated with MNU and saline, as the non-diabetic control; B, 12 db/db mice treated with MNU and saline, as the diabetic control; C, 12 db/db mice treated with MNU and metformin, as the positive control; and D, 12 db/db mice treated with MNU and LDP. MNU was administrated for 20 wk to induce gastric carcinogenesis. LDP was administrated for 10 wk for improvement of insulin resistance. Body weight and food intake were measured every week. Blood samples were collected for assays of fasting blood glucose, insulin, insulin-like growth factor(IGF)-1, adiponectin and leptin. Stomach tissues were collected for histopathological analysis, immunohistochemical staining of Ki67, quantitative reverse transcriptionpolymerase chain reaction and western blotting. RESULTS The incidence of MNU-induced gastric dysplasia was significantly elevated in diabetic(db/db) mice relative to the control(db/m) mice. The incidence of gastricdysplasia was significantly reduced by LDP with suppression of cell proliferation, as demonstrated by a decrease in Ki67 staining. Hyperglycemia, hyperinsulinemia and serum IGF-1 were inhibited by LDP. Expression of IGF-1 and insulin receptor m RNAs was decreased, phosphorylation of IGF-1 receptor and AKT protein was reduced in the stomach tissues by LDP. In addition, adiponectin was increased and leptin was decreased in the serum by LDP. CONCLUSION LDP decreased risk of gastric dysplasia in type 2 diabetic mice by down-regulation of IGF and insulin activity and correction of adipokines disorders.

The compressed ready-only-memory （ROM） file system （CramFS） has been widely used in Linux-based devices. However, it is a read-only filesystem which can not meet the requirement of today＇s smart mobile devices because most of them require updating the software on the air （OTA）. This paper presents a design and implementation of write-enabled CramFS which only introduces minor architecture changes and very limited space filesystems also proves the feasibility of this solution. cost.

Electrochemical conversion of carbon dioxide(CO_(2))to higher-value products provides a forward-looking way to solve the problems of environmental pollution and energy ***,the low solubility of CO_(2)in aqueous electrolytes,sluggish kinetics,and low selectivity hamper the efficient conversion of CO_(2).Here,we report a Au-based hybrid nanomaterial by modifying Au nanoparticles(NPs)with the macrocyclic molecule cucurbit[6]uril(Au@CB[6]).Au@CB[6]displays the optimal selectivity of CO,with the highest CO Faraday efficiency(FECO)reaching 99.50%at−0.6 V *** hydrogen electrode(RHE).The partial current density of CO formed by Au@CB[6]increases dramatically,as 3.18 mA/cm2 at−0.6 V,which is more than ten times as that of oleylamine-coated Au NPs(Au@OAm,0.31 mA/cm2).Operando electrochemical measurement combined with density functional theory(DFT)calculations reveals that CB[6]can gather CO_(2)and lead the increased local CO_(2)concentration near metal interface,which realizes significantly enhanced electrochemical CO_(2)reduction reaction(CO_(2)RR)performance.

随着物流行业的快速发展,物流运输活动中二氧化碳的排放量持续增加。在政府绿色减排的严格要求下,碳排放定会转化成运输企业的内部成本以迫使企业节能减排。基于绿色低碳背景,物流公司在制定配送方案时,应同时考虑经济成本和生态环境保护因素,因此研究带有货物权重的多车型开放式低碳路径问题极为必要。在多车型开放式环境下,以最小总成本(车辆使用固定成本、考虑载重量的运输成本与碳排放成本之和)为目标建立数学模型,并设计了改进的遗传算法并求解。实验结果表明:在单一车型运输模式下,大车型运输是总成本最低、最省钱的模式,而中车型运输则是碳排放量最少、最低碳环保的模式;多车型运输模式下运输组织更优化,车辆装载率更高,运输总成本和碳排放成本均低于单一车型车队,多车型运输模式更经济更省钱,更加符合绿色低碳理念。

作者： Xian Chen Tianmin Wu Zhe-ning Chen Tan Jin Wei zhuang Yisong Zheng State Key Laboratory of Structural Chemistry Fujian Institute of Research on the Structure of Matte~ Chinese Academy of Sciences Fuzhou 350002. China

We review in this article our recent simulation works on modeling peptide T-jump and thermal unfolding Fourier transform infrared spectroscopy(FTIR) and two-dimensional infrared(2DIR) spectra. The theoretical and computational techniques used,including Markov state model(MSM), integrated tempering sampling(ITS) and nonlinear exciton propagation(NEP), are first briefly introduced. The protocols for simulating the thermal unfolding as well as T-jump unfolding are then summarized in details. The simulated spectral features, such as the intensity and ellipticity, are demonstrated to agree well with the experimental observations.

【目的】明确种植抗异丙隆转基因水稻和施用除草剂异丙隆对转基因水稻根际微生物群落的影响,为抗异丙隆水稻种植的生态风险评价提供科学依据。【方法】基于盆栽试验,采用高通量测序技术分析2个抗异丙隆转基因水稻株系及其亲本和施用异丙隆转基因在不同水稻生长阶段的根际微生物群落多样性与组成的差异。【结果】高通量测序结果显示,在水稻所有生长阶段,变形菌门(Proteobacteria)、酸杆菌门(Acidobacteria)、芽单胞菌门(Gemmatimonadota)、拟杆菌门(Bacteroidota)和粘球菌门(Myxococcota)是根际微生物中的优势细菌门;罗兹菌门(Rozellomycota)、子囊菌门(Ascomycota)、担子菌门(Basidiomycota)、球囊菌门(Glomeromycota)和被孢霉门(Mortierellomycota)是根际微生物中的优势真菌门。在水稻相同生长阶段,无论是种植抗异丙隆转基因水稻、非转基因水稻还是施用除草剂异丙隆,水稻根际微生物群落的丰富度指数、辛普森多样性指数和香农多样性指数均未受到显著影响(P>0.05,下同);抗异丙隆转基因水稻、施用异丙隆的转基因水稻与非转基因水稻根际微生物中多数优势微生物门类相对丰度无显著差异,个别优势微生物门在水稻特定的生长阶段发生变化。基于相对丰度前15位微生物属的聚类分析显示,在水稻某些生长阶段根际微生物群落的组成在抗异丙隆转基因水稻、施用异丙隆的转基因水稻与非转基因水稻间存在一定差异。根际微生物群落的主成分分析显示,抗异丙隆转基因水稻、施用异丙隆的转基因水稻和非转基因水稻根际微生物群落组成间无显著差异,但不同生长阶段的根际微生物群落组成出现空间分异。根际微生物群落变差分解分析显示,水稻生长阶段对根际土壤中的细菌群落结构变化的影响为45.62%,而品种和施用异丙隆对根际土壤中细菌群落结构变化的影响分别为1.15%和2.76%;水稻生长阶段对根际土壤中真菌群落结构变化的影响为48.36%,而品种和施用异丙隆对根际土壤中真菌群落结构变化的影响分别为1.36%和2.45%。【结论】种植抗异丙隆转基因水稻和施用异丙隆并未对转基因水稻根际微生物群落产生显著影响,但根际土壤中的细菌和真菌群落一定程度上受水稻生长阶段的影响。
