Construction of Beautiful Countryside in Yongchun County of Fujian Province from Perspective of Watershed Comprehensive Management
近年来,中国正在从经济、社会、生态及人与自然和谐等多角度出发在流域沿岸乡村实施美丽乡村建设。这不仅加快了农村基础设施配套建设,促进了农村生态农业的发展,也极大地增加了农村生态环境治理力度,对流域治理起到了一定的间接推动作用。以福建省桃溪流域永春县的美丽乡村建设为背景,调研美丽乡村实施前后农村生产、生活方式的改变和居民水环境保护意识的变化,并结合水环境监测的手段,对比美丽乡村实施前后桃溪流域污染源强及水质环境的变化,分析美丽乡村建设在流域治理方面的贡献,为美丽乡村建设在推动流域治理方面的作用研究提供重要的理论依据。In recent years, China is implementing a beautiful village building in the watershed coastal villages from economic, social, ecological and harmony between man and nature and other aspects. It is not only speed up rural infrastrueture construc- tion, and promote development of rural ecological agriculture, but also greatly increased rural ecological environment manage- ment efforts, and played a certain indirect role in promoting the basin management. Based on the beautiful countryside construc- tion of Yongchun county in Taoxi River Basin, Fujian province, changes of rural production and lifestyle before and after the im- plementation of beautiful villages and changes of residents' water environment protection consciousness were investigated. Combining with means of water environment monitoring, contribution of beautiful village construction in the basin management was analyzed, and an important theoretical basis for study of role of beautiful countryside in promoting management of river basin was provided
歴史的資源保存地域における観光マネジメントの課題ー白川郷・石見銀山・有松を例としてー
本稿では、白川郷、石見銀山、有松の3つの地域をとりあげ、地域特性に応じた観光マネジメントの課題を明らかにする。これら3地域はともに重要伝統的建造物群保存地区に選定された歴史的資源を観光化することによって維持し、「その中で日常的な暮らしを営み続けている人々」を中心とした「生活と観光のバランス」の取り方における問題に直面している。また、行政区域としては、単独村、地方都市、大都市とそれぞれ位置付けが異なるため、課題の現れ方、解決の仕方としての観光マネジメントの相違点が見えやすく、比較対象のための好事例を提供できると思われる

Tendency of death and life reduction from nasopharyngeal carcinoma in residents in Xiamen City
目的探讨厦门市居民鼻咽癌死亡和减寿的变化趋势,为厦门市鼻咽癌综合防治工作提供依据。方法收集整理2010-2014年厦门市居民鼻咽癌死亡资料计算死亡率、平均减寿年数(AYLL)、死亡率年均变化百分比等评价指标,用GM(1,1)模型对死亡率和AYLL进行预测。结果 2010-2014年,厦门市居民鼻咽癌死亡率2.27/10万,男性死亡率是女性的2.83倍。鼻咽癌造成的AYLL为16.95年。厦门市鼻咽癌死亡率能拟合出GM(1,1)模型,预测值与实际值平均相对误差2.90%~8.32%间,无法拟合AYLL的预测模型。预测2015-2017年鼻咽癌死亡率略有下降。结论 GM(1,1)模型可用于厦门市居民鼻咽癌死亡率的预测,鼻咽癌仍是造成厦门市居民早死的重要原因,不能放松鼻咽癌的预防控制工作。Objective To explore the changing trend of death and years of life loss due to nasopharyngeal carcinoma in residents in Xiamen City so as to provide evidence for its comprehensive prevention and control. Methods The data about residents dying of nasopharyngeal carcinoma in Xiamen City during 2010-2014 were collected and cleared up to calculate the mortality rate,the average years of life loss( AYLL) and the average annual percentage change( APC) of mortality rate,etc. GM( 1,1) model was used to predict the future mortality and AYLL. Results The mortality rate of nasopharyngeal carcinoma in residents in Xiamen City during 2010-2014 was 2.27 / 100,000,and the mortality rate of males was 2.83 times that of females. The AYLL due to nasopharyngeal carcinoma was 16.95 years. All mortality rates of nasopharyngeal carcinoma in Xiamen City could fit out the GM( 1,1) model,but the AYLL could not. The mean absolute percent errors between the simulated values and the observed values were 2.90%-8.32%. The mortality rates of nasopharyngeal carcinoma from 2015 to 2017 were predicted to be decreased slightly.Conclusions The GM( 1,1) model can be used for forecasting the mortality rate due to nasopharyngeal carcinoma in residents in Xiamen City. Nasopharyngeal carcinoma is still an important cause of premature death among residents in Xiamen City; and hence,more attention should be paid to its prevention and control.福建省卫生厅青年科研课题(2014-2-78

Comparison on Microstructure of Anoectochilus roxburghii and A. formosanus
通过石蜡切片和表皮制片观察比较金线莲Anoectochilus roxburghii和台湾金线莲A.formosanus根、茎、叶的显微结构特征。结果表明,金线莲与台湾金线莲显微结构的主要区别在于根皮层厚度、维管束数目、叶构造、叶脉颜色、表皮乳头细胞的形状和气孔密度,这些特征可作为金线莲物种的显微鉴别依据。The microscopic structures of roots, stems, leaves of Anoectochilus roxburghii and A. formosanus were observed by paraffin sections and epidermis. The results showed that differences of microstructure between both plants are on cortex thickness and number of vascular bundle of root, and the structure, vein color, papilate cell shape, stomatal density of the leaf. All of these differences can be used as microspcopic identification of both plants.漳州市科技计划项目(ZZ2016J27);; 漳州卫生职业学院课题(ZYZ201401

非酒精性脂肪性肝病无创性诊断方程的构建
目的利用与非酒精性脂肪性肝病(NAFLD)相关的常用临床及实验室指标,构建无创性诊断方程,并评估该方程对NAFLD的预测及诊断价值。方法选取2016年11月-2017年11月西安医学院第一附属医院诊断为NAFLD患者127例和健康对照者30例,记录研究对象的性别、年龄、BMI、病史、ALT、AST、GGT、尿素氮(BUN)、尿酸(UA)、血肌酐(Cr)、TC、TG、HDL、LDL、糖化血红蛋白(HBA1c)、游离脂肪酸(FFA)、空腹血糖(FPG)、空腹胰岛素(FINS)、PLT、超声检查结果和Fibro Scan的检查结果等数据。计量资料组间比较采用t检验,相关性使用Pearson相关性分析,回归方程的构建使用多元线性回归方程模型,构建受试者工作特征曲线(ROC曲线),计算回归方程的敏感度和特异度。结果与脂肪肝相关的指标包括BMI(r=0.308,P=0.005)、ALT(r=0.379,P<0.001)、AST(r=0.318,P=0.004)、GGT(r=0.293,P=0.009)、UA(r=0.244,P=0.033)、FFA(r=0.249,P=0.030);对Fibroscan的受控衰减参数(CAP)相关指标进行多重回归分析,CAP的回归模型具有统计学意义(F=11.113,P<0.001),其校正决定系数R2=0.274,说明回归引起的变异在总变异中所占的比率为27.4%,对CAP影响最大的指标是ALT(β=0.358,P=0.001),其次是BMI(β=0.258,P=0.012<0.05),构建的回归方程为CAP=113.163+0.252×ALT+6.316×BMI,诊断方程的ROC曲线下面积为0.927,灵敏度为87.68%,特异度为90.00%,cut-off值为277.67,P<0.001,具有较高的诊断效能。结论与目前已有的诊断方程相比,此方程的ROC曲线下面积、特异度、灵敏度均较佳,计算方法最为简单,实用性及可操作性强,有利于便捷筛查出早期NAFLD,提高自我干预意识,进一步降低NAFLD的全球危害和疾病进程。可以作为一个诊断NAFLD的方程,供临床参考及推广。陕西省普通高等学校优势学科建设项目(陕教位[2014]3号文件
