剡溪山水文化旅游资源开发设想     

邱德玉 《四川畜牧兽医学院学报》2005,3(4):5-8

文化底蕴越是丰厚的旅游资源，开发价值就越高。正是众多文人贤士游剡访古，使浙东剡溪的历史、文化与自然山水完美地结合在一起，形成了绚丽多彩的剡溪山水文化。文化被认为是旅游业的灵魂，是一种潜在的旅游产品。要提高山水旅游产品的文化品位，必须将山水文化的潜在价值转化为旅游产品。本文对剡溪山水文化旅游资源的开发提出了以下设想：再现“唐诗之路”山水旅游美景，并着重于按唐诗及有关文献、传说等增添新景点，沿江、沿山、于水中进行山水、文化全面开发，形成立体式、全景式的剡中山水文化游道；可开发出文化生态、修学、科考、宗教、节庆等剡溪山水文化旅游产品。  相似文献

研究网络文化改进高校思想政治教育     

冯沈萍 《四川畜牧兽医学院学报》2005,3(4):167-170

网络文化具有不同于现实丰十会文化形态的特性，网络文化的特性使网络用户作为主体参与网络活动具有不同于现实社会生活主体的特点。大学生是网络文化活动的重要参与者。高校思想政治教育应当研究网络文化与大学生的互动关系以及网络文化对大学生成长的影响，在坚持优良传统的基础上不断创新，积极主动地运用现代科技手段，营造良好的网络文化环境，卓有成效地开展网络思想政治工作，引导大学生健康成长。  相似文献   

法律本科教学方法之我见     

杨胜玲 《四川畜牧兽医学院学报》2005,3(4):195-197

随着我国法治的不断健全，对新时期法律本科教育提出了新的要求，这也是对中国法学教育者传统教学方法的一次新挑战。需要我们吸收传统教学方法的优秀经验，探索适合本科阶段教育特色的教学方法，开展案例教学和实践教学，注重教学中的师生互动关系，改革考试内容和考试方式，以使现阶段法学本科教育更能适应现实社会和法律职业的需求。  相似文献   

阜康绿洲土壤盐渍化特征及其与肥力的相关性分析   总被引：9，自引：0，他引：9  

顾峰雪  张远东  刘永强  初雨  潘晓玲 《干旱区资源与环境》2003,17(2):78-82

本文以电导、可溶性总盐含量和pH作为指标,将阜康绿洲的盐渍化类型划分为9种,其中以强盐渍土和盐土为主,在纬度梯度上从南至北,即从洪积扇下部到沙漠按照中盐渍土-强盐渍土-盐土-强盐渍土-盐土-非盐渍土的顺序依次分布。而土壤含水率却是从洪积下部至扇缘溢出带逐渐升高,在细土平原地区差异较大,在沙漠中又迅速降低。通过土壤剖面中有机质、全量N、P、K和速效N、P、K的分析,结果表明阜康荒漠自然状态下土壤肥力很低,各养分含量在空间上呈现规律性的变化,在纬度梯度上逐渐升高又在沙漠中降低。通过水盐与土壤肥力的相关性分析,结果表明:有机质、全N、P和速P与含水率、电导、总盐均具有显著和极显著正相关,而与pH成负相关,但相关性不显著。由于盐生植物的多样性,在盐渍土和盐土土壤肥力并无显著降低,只是土壤溶液的高盐浓度限制了植物对养分的吸收,因此防止和治理土壤盐渍化是发挥土地生产潜力的重要手段。  相似文献   

Association of polymorphism of Fc receptor γ chain gene at position-29 in promoter with the susceptibility to systemic lupus erythematosus in southern Chinese     

ZHOU Shu-lu  YE Ren-gao  LIU Xiao-bo  ZHANG Hong  XU Han-shi  DU Yong  LI You-ji  YANG Nian-sheng  YANG Xiao  YU Xue-qing 《园艺学报》2003,19(6):782-785

AIM:To detect the association between the polymorphism of Fc receptor γ chain gene at position-29 in promoter and systemic lupus erythematosus(SLE).METHODS:The genotypes at position -29 in promoter of Fc receptor γ chain gene were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method in 180 patients with SLE and 140 ethnically matched controls in southern China.RESULTS:The frequencies of TT genotype(33.3%) and T allele (54.4%) at position -29 in patients with SLE were significantly higher than those in controls (17.2% and 42.9%, respectively), whereas, the frequencies of GG genotype (24.4%) and G allele (45.6%) in patients with SLE were remarkably lower than those in controls (31.4% and 57.1%, respectively) (P＜0.05). The TT genotype and T allele at position -29 were not associated with lupus nephritis in SLE patients (P＞0.05).CONCLUSION:Our results indicate that the T allele at position -29 in promoter of Fc receptor gene probably contributes to the susceptibility to SLE, but does not play a role in the occurrence of lupus nephritis.  相似文献   

The application of atomic force microscope in clinic diagnosis of erythrocytes     

CHEN Yong  CAI Ji-ye 《园艺学报》2003,19(1):27-31

AIM: To investigate the application of atomic force microscope (AFM) in clinic diagnosis. METHODS: Topographic images and some parameters of large range field and microstructures of erythrocytes in the blood of normal subjects, lung cancer and myelodisplastic syndrome (MDS) patients were examined by atomic force microscope. RESULTS: Many clear topographic images of many erythrocytes, single erythrocyte, and microstructure of erythrocyte membrane surface were obtained. Many erythrocytes in lung cancer patients were found to change into echinocytes. One erythrocyte had 10-20 protuberances, most of which, with a mean width of 589. 0 nm and a length of 646. 7 nm, were on the edge of cells. The protuberances on the center of echinocytes are lodged and embedded. The erythrocytes of MDS patients were biconcave in shape. Many apertures with different diameters of tens to hundreds nanometer appeared on the surface of cell membrane. CONCLUSIONS: AFM can be widely applied in clinic pathological inspection, including quantification of cells, obtainment and comparison of many parameters (such as diameter, thickness, volume, surface, surface area/volume ratio), observation of topograph of single cell, and observation and comparison of membrane surface microstructure of cells, and so on.  相似文献   

Effects of TGF-β₁ and TNF-α antisense PS-ODNS on ex vivo expansion of hematopoietic stem/progenitor cells(HSPC)     

HUANG Mei-juan  CHEN Yuan-zhong  WU Yong  LI Nai-nong  ZHANG Zhao-xiu 《园艺学报》2003,19(10):1375-1378

AIM:To study the effect of TGF-β₁ and TNF-α antisense PS-ODNS on ex vivo expansion of hematopoietic stem/progenitor cells (HSPC). METHODS:CD₃₄⁺cells were purified from fresh umbilical cord blood by immunomagnetic beads, and mononuclear cells were purified from bone marrow by Ficoll-hypaque. The effects of TGF-β₁ and /or TNF-α antisense PS-ODNS on ex vivo expansion of CD₃₄⁺ cells、CFU-GEMM、CFU-GM、CFU-E and BFU-E were detected by using liquid and semi-solid culture systems.RESULTS:TGF-β₁ antisense PS-ODNS cooperated with cytokines increased the number of CD₃₄⁺ cells, CFU-GEMM, CFU-GM, CFU-E and BFU-E, which was as 4, 2.6, 2.7, 1.8, 2.1 times as that of the control (the cytokines combination), respectively. TNF-α antisense PS-ODNS cooperated with cytokines respectively increased the number of CD₃₄⁺ cells, CFU-GEMM, CFU-GM, CFU-E and BFU-E by 4, 2.9, 2.6, 1.7, 1.8 times as that of the control. The above two antisense PS-ODNS cooperated with cytokines could respectively increased the number of CD₃₄⁺ cells, CFU-GEMM, CFU-GM, CFU-E and BFU-E by 5.3, 2.1, 2.7, 1.9, 1.8 times as that of the control.CONCLUSION:Inhibition of endogenous TGF-β₁ and TNF-α by antisense PS-ODNS will be one of the effective methods to expand HSPC ex vivo.  相似文献
