Monitoring and minimizing tourist’s water consumption is essential for the sustainable development of mountain destinations in the world. However, available data and a generally accepted protocol on such measurement are still limited. This study uses water footprint accounting to quantify tourist’s water demand in the Liming valley, a World Heritage site and a rapidly growing tourism destination in Northwest Yunnan, China. Both the water for direct and indirect use is taken into account based on the consumptive behavior of the tourists in the valley. Data were collected through guesthouse monitoring and a tourist survey in the 2005 tourist season. The results indicate that an average tourist leaves behind a footprint of 5.2 m3 on local water resources per day. Food production and waste dilution are the two most important water consumption factors. The results also show tourists consume more water than the local residents on per capita basis. This suggests more commitment is necessary to cope with this stress by individual tourists. Management implications to make water use more sustainable in mountain destinations are derived from this study.

Water and air quality of eight seawater swimming pools using chlorine disinfection was measured during four sampling campaigns, spread on one full-year, and in four thalassotherapy centers located in Southeast of France. Concentrations of trihalomethanes（THMs） in air and in water as well as concentrations of parameters, including nonpurgeable organic carbon（NPOC）, free residual chlorine（Cl_f）, pH, Kjeldhal Nitrogen（KN）, salinity,conductivity, bromide ions and, water and air temperature, were measured. Water and air samples were collected in triplicates morning — at the opening of the pools —, noon and night — at the closing of the pools —, in summer and winter. Data analysis was performed by Principal Component Analysis（PCA） and rotated component matrix, from both data quality and other parameters such as TOC, aromaticity（UV_（254））, pH, hygrometry, and free residual chlorine（Cl_f）. This statistical analysis demonstrates a high correlation between TOC, Cl_fand UV_（254） and THM levels found in air and water, particularly for the major ones（CHBr_3in water：300.0 μg/L mean, 1029.0 μg/L maximum; CHBr_3 in air： 266.1 μg/m^3 mean,1600.0 μg/m^3 maximum, and CHClBr_2 in water： 18.9 μg/L mean, 81.0 μg/L maximum;CHClBr_2 in air： 13.6 μg/m^3 mean, 150.0 μg/m^3maximum）. These high levels of bromoform（CHBr_3） are particularly worrisome in such health institutions, even these levels do not exceed the Permissible Exposure Limit（PEL） of 5 mg/m^3 as an 8 hour time-weighted average currently fixed by various administrations, such as Occupational Safety and Health Administration（OSHA）.

目的探究微小RNA(miRNA)-365a-3p影响血管内皮细胞功能参与子痫前期(PE)的发病机制。方法分离原代人脐静脉内皮细胞(HUVECs),设为NC组(转染miR-365a-3p NC)、mimics组(转染miR-365a-3p mimics)、inhibitor组(转染miR-365a-3p inhibitor),另取对数期细胞设为空白组。检测各组增殖、迁移及血管形成能力。双荧光素酶实验验证miR-365a-3p与下游基因的靶向关系。检测各组TGF-β_(1)、Smad4、Smad7蛋白表达。结果与空白组、NC组比较,mimics组24、48、72 h吸光度值及迁移率降低(P<0.05),每个视野的管状结构数量减少(P<0.05),inhibitor组24、48、72 h吸光度值及迁移率升高(P<0.05),每个视野的管状结构数量增加(P<0.05)。双荧光素酶实验表明Smad7是miR-365a-3p的一个靶基因。与空白组、NC组比较,mimics组转化生长因子-β_(1)(TGF-β_(1))、Smad4蛋白表达升高(P<0.05),Smad7蛋白表达降低(P<0.05),inhibitor组TGF-β_(1)、Smad4蛋白表达降低(P<0.05),Smad7蛋白表达升高(P<0.05)。结论miR-365a-3p可能通过调控下游TGF-β信号通路影响血管内皮细胞功能,从而参与PE发病。

In this paper, continuing with Hu-Li Vrancken and the recent work of Antid Dillen- Schoels-Vrancken, we obtain a decomposition theorem which settled the problem of how to determine whether a given locally strongly convex aitine hypersurface can be decomposed as a generalized Calabi composition of two affine hyperspheres, based on the properties of its difference tensor K and its affine shape operator S.
