| 1 | 内皮细胞和平滑肌细胞氧化应激时Nrf2/ARE信号通路对抗氧化基因表达的调控:与动脉粥样硬化和先兆子痫的关系显示文摘动脉粥样硬化、糖尿病、慢性肾功能衰竭和先兆子痫等血管疾病时活性氧(reactive oxygen species,ROS)生成增加,容易导致内皮依赖性血管舒张功能的损害和血管损伤,而细胞可以诱导多种编码Ⅱ相解毒酶和抗氧化蛋白的基因表达,从而减轻ROS和亲电子物质介导的细胞损伤。一个被称为抗氧化反应元件(antioxidant response element,ARE)或亲电子反应元件(electrophile response element,EpRE)的顺式转录调控元件,可以介导诸如亚铁血红素加氧酶1、γ-谷氨酰半胱氨酸合成酶、硫氧还蛋白还原酶、谷胱甘肽-S转移酶和NAD(P)H:苯醌氧化还原酶等基因的转录。其他抗氧化酶,如超氧化物歧化酶、过氧化氢酶和非酶清除剂(如谷胱甘肽)等也参与ROS的清除。转录因子NF-E2相关因子2(nuclear factor-erythroid 2-related factor 2, Nrf2)是属于Cap‘n’Collar家族的转录因子,具有碱性亮氨酸拉链(basic region-leucine zipper,bZIP),它在ARE介导的抗氧化基因表达中起重要的作用。在正常情况下,Kelch样环氧氯丙烷相关蛋白-1(Kelch-like ECH-associated protein-1,Keapl)与Nrf2耦联,并与肌动蛋白细胞骨架结合被锚定于胞浆,但是在半胱氨酸残基发生氧化的情况下,Nrf2和Keapl解耦联,进入细胞核并与ARE结合,从而激活多种抗氧化基因和Ⅱ相解毒酶基因的转录。蛋白激酶C、丝裂原活化蛋白激酶和磷脂酰肌醇-3激酶参与Nrf2/ARE信号转导的调控。本文综述了有关Nrf2/ARE信号转导通路在血管稳态和动脉硬化、先兆子痫等疾病情况下内皮及平滑肌细胞对抗持续性氧化应激中起的作用。 | Giovanni E.

| 3 | GIS-based risk analysis of debris flow:an application in Sichuan,southwest China显示文摘Debris flow is a serious geologic hazard in China.It is estimated that nationally debris flows cause up to 2 billion RMB(250 million US$) in damages and 300-600 deaths and injuries annually.To mitigate debris flow hazards,it is necessary to map,model,and identify zones of debris flow hazards and vulnerability as to inform the local people about the potential risk with a geographic information system.This research presents a regional scale case study modeling debris flow risk(hazard and vulnerability) in Sichuan Province,Southwestern China.In this area,3,290 debris flows have been identified and the spatial-temporal distribution and activity characteristics of them have been documented.Based on the available meteorological data,a Digital Elevation Model with the rate of 1:250,000 and a regional geological map,the 24-hr rainfall threshold(y) for debris flow occurrence is closely related(significant at 99% confidence level) to the index(x) defined using a geology factor(rock hardness:a) and a topographical factor(channel gradient:d) where y = 21 + 10200 / x,in which x = 2.7 × ea + 1000 × d.The discipline is constructive in developing the rainfall threshold for debris flow activity in remote mountainous areas that lack data.For a given watershed,a four-level debris flow hazard map is developed by comparing the rainfall threshold to the design rainfall intensities with 50-,20-,and 5-year average recurrence intervals,respectively.The degree of debris flow vulnerability is determined by the watershed socio-economic conditions.A four-class debris flow risk map,at the final phase of the research,is generated by combining debris flow hazards and vulnerability.With the debris flow risk assessment,the Sichuan Province is classified into the slight,moderate,severe and very severe regions,which accounts for 36%,19%,20% and 25% of total area respectively. | B.

| 4 | THE INFLUENCE OF CAVITY DAMAGE ON MECHANICAL PROPERTIES OF SUPERPLASTICALLY-DEFORMED MATERIALS AND ITS PREDICTION显示文摘Aluminium alloy LY12CZ sheet without any pre-treatment has been used to study the influence of cavity damage on the mechanical properties of the superplastically-deformed materials room temper- ature. The experimental results show that: (1) the lower the rate of cavitation as the superplastic strain increases, the higher the superplasticity is; (2) the mechanical properties of superplastically- deformed materials at room temperature decrease as the superplastically-deformed strain increases, especially, a noteworthy decrease in elasticity modulus, yield strenth and ultimate strength at room temperature begins to appear as the level of cavitation by area comes up to about 4%, while at the same level the reduction in area drops down a very large quantity. Then, a three-layer back- propagation neural network has been developed to predict the machanichl properties of the superplasti- cally-deformed material.The results acquired from the neural network are very | M.

| 10 | High universality of matK primers for barcoding gymnosperms显示文摘DNA barcoding is a tool to provide rapid and accurate taxonomic identification using a standard DNA region.A two-marker combination of matK+rbcL was formally proposed as the core barcode for land plants by the Consortium for the Barcode of Life Plant Working Group.However,there are currently no barcoding primers for matK showing high universality in gymnosperms.We used 57 gymnosperm species representing 40 genera,11 families and four subclasses to evaluate the universality of nine candidate matK primers and one rbcL primer in this study.Primer(1F/724R) of rbcL is proposed here as a universal primer for gymnosperms due to high universality.One of the nine candidate matK primers(Gym_F1A/Gym_R1A) is proposed as the best 'universal' matK primer for gymnosperms because of high polymerase chain reaction success and routine generation of high quality bidirectional sequences.A specific matK primer for Ephedra was newly designed in this study,which performed well on the sampled species.The primers proposed here for rbcL and matK can be easily and successfully amplified for most gymnosperms. | Yan LI Lian-Ming GAO Ram C.

| 11 | Possible effect of ENSO on annual sediment discharge of debris flows in the Jiangjia Ravine based on Morlet wavelet transforms显示文摘The multi-time-scale structures of an annual sediment discharge series of debris flow in the Jiangjia Ravine and the Southern Oscillation index are analysed using the method of Morlet wavelet transformations. The possible effects of El Nio episodes on the annual sediment discharge are discussed by comparing the period variations of ENSO and the discharge. The results show that the annual sediment discharge series of debris flow is related to El Nio episodes. Generally, the annual sediment discharge of debris flow is less than usual during an El Nino episode and debris flow is less active. On the contrary, the annual sediment discharge of debris flows is greater than usual during a La Nia episode and debris flows are more frequent. There is a relationship between the annual sediment discharges of debris flow in the Jiangjia Ravine and the summer Southern Oscillation index, with both having quasi-periodic variations of 2 and 5–6 years. | J.

| 14 | Melanopsin-expressing retinal ganglion cell loss and behavioral analysis in the Thy1-CFP-DBA/2J mouse model of glaucoma显示文摘In this study,the role of melanopsin-expressing retinal ganglion cells(mRGCs) in the glaucoma-induced depressive behavioral response pattern was investigated.The CFP-D2 transgenic glaucoma animal model from five age groups was used in this study.Immunohistochemical labeling,quantitative analysis of mRGC morphology,open field test(OFT),and statistical analysis were used.In comparison with C57 BL/6 mice,the age-matched CFP-D2 mice had significantly elevated intraocular pressure(IOP).We observed parallel morphological changes in the retina,including a reduction in the density of cyan fluorescent protein(CFP) expressing cells(cells mm 2 at 2 months of age,1309±26;14 months,878±30,P<0.001),mRGCs(2 months,48±3;14 months,19±4,P<0.001),Brn3b-expressing RGCs(2 months,1283±80;14 months,950±31,P<0.001),Brn-3b expressing mRGCs(5 months,50.17%±5.5%;14 months,12.61%±3.8%,P<0.001),and reduction in the dendritic field size of mRGCs(mm2 at 2 months,0.077±0.015;14 months,0.065±0.015,P<0.05).CFP-D2 mice had hyperactive locomotor activity patterns based on OFT findings of the total distance traveled,number of entries into the center,and time spent in the center of the testing apparatus.The glaucoma induced hyperactive response pattern could be associated with dysfunctional mRGCs,most likely Brn-3b-positive mRGCs in CFP-D2 mice. | ZHANG Qi VUONG Helen HUANG Xin WANG YanLing BRECHA Nicholas C.

| 16 | The level of oncogene H-Ras correlates with tumorigenicity and malignancy显示文摘Normal bovine adrenocortical cells and some human fibroblasts can be transformed by SV40T and H-Ras in a Ras-dependent manner. We recently reported that high levels of Ras derived from 5' LTR of retrovirrus can induce highly malignant and fast growing tumors, while lower levels of Ras derived from internal ribosome entry site(IRES) promotes slower tumor growth and loss of malignancy. Ras derived from CMV promoters resulted in much lower Ras levels and loss of tumor malignancy and growth. Further studies showed that the tumors formed in the presence of lower levels of Ras and dominant negative P53(P53DD) had fewer apoptotic cells and grew faster than the tumors formed from cells with same level Ras and SV40T. Our studies suggest that low levels of Ras are insufficient to inhibit apoptosis induced by pRb inactivation. In contrast, high levels of Ras not only allow normal cells to exit senescence and form tumors, but also protect against pRb inhibition-induced cell apoptosis. | Sun, B. C. Gao, Y. Deng, L. Li, G. Q.

| 17 | EVOLUTION OF THE ELECTROCHEMICAL CHARACTERISTICS DURING PITTING CORROSION OF PURE ALUMINUM IN SODIUM CHLORIDE SOLUTION显示文摘The corrosion behavior of pure aluminum in neutral 3.0% (mass fraction) sodium chloride (NaCl) solution has been studied using electrochemical impedance spectroscopy (EIS) measurement in conjunction with the scanning electron microscopy (SEM) technique. EIS information on the evolution of pitting corrosion over a period of 15 days has been obtained and analyzed with equivalent circuit technique. The results shown that, during the ensemble constant immersion time, two time constants involved, the high frequency one originated from the protective layer on the corroding surface while the low frequency one from the diffusion process or the corrosion reaction and so on. And there existed a period for oxide film to growth and thickening prior to the commencement of the attacking of chloride ions to the substrate. Meanwhile, good relationship between EIS and the material corrosion type/ severity has been obtained, which has been interpreted according to the characteristics of corrosion process such as auto acceleration of pitting corrosion and the protection of local anodic reaction to the area around them. | Z.
