In this study, objective differences between the Cold (Han) and Hot (Re) nature of traditional chinese medicines, e.g. Strobal and Rhubarb, are determined by using a cold/hot plate differentiation technology. A novel, self-designed cold/hot plate differentiating instrument, with methodological study, was used to investigate the intervention of Strobal and Rhubarb on the temperature tropism of mice. Compared with the ICR and BALB/c mice, it was found that KM mice on the cold/hot plate were more sensitive to the change of temperature, within the tolerant temperature range of 15-40 ℃ . The temperature tropism behavior of mice is influenced by treatment with Rhubarb and Strobal, as is the activity of ATPase in liver tissue. These trends are consistent with the definition of the Cold/Hot nature of chinese medicines based on traditional chinese medicinal theory. This study showed that the differences of the Cold/Hot nature of traditional chinese medicines. might be objectively represented by the temperature tropism of animal by means of cold/hot differentiating assay.

准确的物质组成信息是解译行星体形成与演化历史的关键,可见–近红外遥感光谱探测一直是获取行星表面成分的主要技术手段.在热红外谱段光谱特征更为丰富,因此随着探测技术的发展,其在行星探测中得到越来越多的应用.尤其是在目前已经实施与立项的国内外小行星探测任务中,都将热发射光谱仪作为核心载荷之一.为了更好地对将来获取的热发射光谱数据进行解译,建立科学合理的数据处理与定标方案是必不可少的.本文对用于行星科学研究的热发射光谱测量装置的设计、测量及数据处理方法进行了系统分析.针对低温、真空条件下热发射测量过程中样品辐射信号与仪器辐射信号难以分离的问题,提出并论证了基于傅里叶变换红外光谱仪原始测量信号–干涉图的数据处理方法.该方法可以更为有效地分离出样品实际辐射信号,从而获得更为准确的发射率光谱数据.研究结果可为国内相关热发射测量装置的设计与搭建以及未来天问二号等探测数据的处理与科学解译提供参考.

随着我国交通系统的发展及汽车车速的日益提升,坐落于道路两旁的框架建筑承受的车辆碰撞风险也与日俱增.超高性能混凝土(Ultra-High Performance Concrete, UHPC)由于其超高的材料断裂能以及抗拉能力逐渐被应用于框架结构中以提高其使用性能.UHPC框架结构同样承受较高的车辆撞击风险.本文建立了三维动力非线性的车辆-UHPC三层框架结构碰撞模型并采用Ansys/LS-DYNA进行求解.采用已发表的落锤撞击普通混凝土(Normal Concrete, NC)与超高性能混凝土(UHPC)梁试验对材料参数与接触算法的正确性进行了验证.基于三维动力非线性碰撞模型,从结构损伤、碰撞力特性及结构耗能机理三方面对NC及UHPC框架结构进行了全面对比.主要结论如下:(1) UHPC框架结构的抗车辆冲击性能远高于NC框架结构.UHPC框架结构的损伤仅存在于被撞柱,其他部位混凝土的使用性能几乎不受影响.(2)高车速条件下(80~120 km/h),NC柱的损伤分布为剧烈的冲切损伤并伴有明显的塑性变形,框架节点出现明显的受拉及受剪损伤;UHPC柱的背面始终不出现受拉区域,最终发展成贯通框架柱截面的冲剪破坏.(3) NC柱的混凝土内能均比UHPC柱的混凝土内能高,导致NC柱的损伤程度比UHPC柱严重.(4)当车辆保险杠撞击框架柱时,碰撞力产生第一个峰值;当车辆引擎与框架柱撞击时,碰撞力产生第二个峰值.引擎撞击产生的碰撞力峰值均远高于保险杠撞击.UHPC柱的碰撞力峰值平均比NC柱高22.6%,二者碰撞力峰值最大差异可达32.1%.本文研究结果有助于促进UHPC框架结构的抗冲击合理化设计,并保障其安全健康运营.

AIM: To study the association between APOe polymorphisms and cerebral infarction through a case-control study among the chinese Han population. MeTHODS: First-ever cerebral infarction patients (n=226) whose ages ranged from 40 to 60 years old were recruited from Department of Neurology, Zhongshan Hospital, Shanghai, and Zhejiang chinese Traditional Medicine Hospital, Zhejiang, China. Unrelated healthy controls (n=201) were selected from the general population in the same area with similar age and sex distribution. APOe was amplified by one-stage PCR using the forward primer: 5'-GGC ACG GCT GTC CAA GGA GCT-3' and reverse primer: 5'-GAT GGC GCTGAG GCC GCG CT-3'. The PCR product was digested directly with 5 U of CfoI and separated by a 20 % polyacryla- mide (acrylamide: bis-acrylamide=29:1) nondenaturing gel. ReSULTS: Both cerebral infarction patient and control groups were in Hardy-Weinberg equilibrium. The allele frequency of APOe*2, APOe*3, and APOe*4 was 4.6 %, 81.9 %, and 13.5 % respectively in the patients with cerebral infarction; 5.7 %, 87.3 %, and 7.0 % respectively in the healthy control group. Compared with APOe3/3 subjects, APOe4/4 carriers had a 2.1-fold risk of cerebral infarction (odds ratio 2.1, 95 % confidence limits 1.3 to 3.4). The allele frequency of APOe*4 in the cerebral infarction patient group was significantly higher than that in the control group (13.5 % vs 7.0 %; P=0.002). CONCLUSION: APOe 4 is a risk factor for cerebral infarction among the chinese Han population.

The present paper analyzes the potential impacts of bio-ethanol expansion on agricultural production, food prices and farmers＇ incomes in different regions of China. The results show that increase in demand for feedstock to produce bio-ethanol will lead to large increase in the prices of agricultural products. The increase in prices will trigger a significant rise in the production of feedstock at the cost of lower rice and wheat production. The study also reveals that the impacts of bio-ethanol on farmers＂ incomes vary largely among regions and farmer groups. Given the expected expansion of bio-ethanol production in the future, and the limited land resources for feedstock production in China, the viability of different crops as feedstock for bio-ethanol requires careful analysis before a large-scale expansion of China＇s bio-ethanol program. Bio-ethanol production in China should be relying more on the second generation of bio-ethanol technologies （i.e. using celluloses to produce bio-ethanol）, and China＇s government should increase research investment in this field.

A simulation experiment on vertical transport of herbicide atrazine (2 chloro 4 ethylamino 6 isopropylamino s triazine) in soil column was conducted using lysimeter system. The atrazine concentrations in leaching water and soil samples in column at 8 layers with 10 cm thick of each layer were detected by high performance liquid chromatography. The results show total atrazine amount in leaching water increases nonlinearly with the leaching time and the herbicide application rate, and the atrazine concentrations in column soil decrease with the vertical depth after water leaching. The distribution of atrazine mass in the system after 154 days were that among the applied atrazine, 0.3% is out through leaching water, 1% is methanol extractable residues in soil, 46% is methanol nonextractable residues in soil, and 52% is other loss (including volatilization and degradation). The study indicates movement of atrazine in agriculture soil may not only have relation to the properties of herbicide, but also to the herbicide application history.

本文基于中国家庭追踪调查数据(CFPS),运用双向固定效应模型,实证考察公共转移支付对家庭消费相对剥夺的影响及作用机理。研究发现,公共转移支付可以显著缓解家庭消费相对剥夺。经过一系列稳健性检验并缓解潜在的内生性问题后,研究结论依然成立。异质性分析表明,相比于民生性转移支付,生产性转移支付显著缓解了家庭消费相对剥夺;公共转移支付对贫困县和高抚养比家庭的消费相对剥夺影响更大。机制分析表明,公共转移支付主要通过降低家庭收入相对剥夺、改善收入不确定性和提高社会信任水平来缓解家庭消费相对剥夺。本研究为缓解个体消费相对剥夺、改善居民福利水平,进而实现共同富裕提供了微观证据。
