This study illustrates the urbanization in Shijiazhuang city and its impacts on local micro-climatic and hydrological environments change using remote sensing. Firstly, a pair of Landsat TM images of study area in 1987 and 2001 is used for detecting urban expansion and associated land cover change. Together with detecting urban expansion and associated land(More)
Intensive fertilization and irrigation associated increasing grain production has led to serious groundwater depletion and soil/water pollution in the North China Plain (NCP). Intensive agriculture changes the initial mass and energy balance, and also results in huge risks to the water/soil resources and food security regionally. Based on the research(More)
In order to study the surface energy budget of the cropland in North China Plain, this paper discussed the characteristics of heat and CO2 fluxes of the cropland during the winter wheat growing, and then simulated the dynamic change of the flux of heat and carbon by SiB2 (simple biosphere model Version2) based on the observational data from 2005-10-10 to(More)
Recently, we reported that Ilexgenin A exhibits anti-cancer activities and induces cell arrest. Here, we investigated the effect of Ilexgenin A on the inflammation, angiogenesis and tumor growth of hepatocellular carcinoma (HCC). Our current study revealed that Ilexgenin A significantly inhibited the inflammatory cytokines TNF-α and IL-6 levels and(More)
OBJECTIVE To evaluate anti-melanoma effect of ethanol extract of Ilex hainanensis Merr. (IME) and elucidate its underlying mechanism. METHODS Thirty-six tumor-bearing mice were randomized into 6 groups (n=6) as follows: model group, IME 25, 50, 100, and 200 mg/kg groups and dacarbazine (DTIC) 70 mg/kg group. The mice in the IME treatment groups were(More)
