The response of natural vegetation to climate change is of global concern. In this research, changes in the spatial pattern of major terrestrial ecosystems from 1956 to 2006 in Inner Mongolia of China were analyzed with the Holdridge Life Zone (HLZ) model in a GIS environment, and net primary production (NPP) of natural vegetation was evaluated with the Synthetic model, to determine the effect of climate change on the ecosystem. The results showed that climate warming and drying strongly influenced ecosystems. Decreased precipitation and the subsequent increase in temperature and potential evapotranspiration caused a severe water deficiency, and hence decreased ecosystem productivity. Climate change also influenced the spatial distribution of HLZs. In particular, new HLZs began to appear, such as Warm temperate desert scrub in 1981 and Warm temperate thorn steppe in 2001. The relative area of desert (Cool temperate desert scrub, Warm temperate thorn steppe, Warm temperate desert scrub, Cool temperate desert and Warm temperate desert) increased by 50.2% over the last half century, whereas the relative area of forest (Boreal moist forest and Cool moist forest) decreased by 36.5%. Furthermore, the area of Cool temperate steppe has continuously decreased at a rate of 5.7% per decade; if the current rate of decrease continues, this HLZ could disappear in 173 years. The HLZs had a large shift range with the mean center of the relative life zones of desert shifting northeast, resulting a decrease in the steppe and forest area and an increase in the desert area. In general, a strong effect of climate change on ecosystems was indicated. Therefore, the important role of climate change must be integrated into rehabilitation strategies of ecosystem degradation of Inner Mongolia. © 2010 Blackwell Publishing Ltd.

Batch adsorption experiments were carried out for the removal of methylene blue (MB) cationic dye from aqueous solution using chitosan- g-poly (acrylic acid)/attapulgite composites (CTS- g-PAA/APT) as adsorbent. The effects of attapulgite (APT) content, initial pH value of the dye solution and temperature on adsorption were investigated. Results showed that APT content of composites had some influence on adsorption capacities, and introducing a small amount of APT could improve adsorption capacity of chitosan- g-poly (acrylic acid) (CTS- g-PAA) to a certain extent. Results from kinetic experimental data showed that the adsorption rate of MB on CTS- g-PAA and CTS- g-PAA/APT with 30% of APT was fast, and more than 90% of the maximum adsorption capacities for MB were achieved within the initial 15. min. The adsorption behaviors of CTS- g-PAA and CTS- g-PAA/APT showed that the adsorption kinetics and isotherms were in good agreement with a pseudo-second-order equation and the Langmuir equation, and the maximum adsorption capacities reached 1873 and 1848. mg/g for CTS- g-PAA and CTS- g-PAA/APT, respectively. The discussion results of the desorption studies implied that CTS- g-PAA and CTS- g-PAA/APT can be used as promising adsorbents for the removal of MB from wastewater. © 2010 Elsevier B.V.

Separating effects of climate change (δ. Qc) and human activity (δ. Qh) on stream discharge at the watershed scale is needed for developing adaptive measures to climate change. However, information is scarce in existing literature regarding whether such separating is feasible and whether reliable results can be produced. The objectives of this overview were to: (1) compare currently-used methods; (2) assess assumptions and issues of the methods; and (3) present a generic framework that overcomes possible issues. Based on the overview of fifteen recent representative studies, two methods can be used to estimate absolute magnitudes of δ. Qc and δ. Qh, while another method can be used to distinguish relative magnitudes of δ. Qc versus δ. Qh only. Because the methods' fundamental assumptions about baseline versus altered period, water storage change and deep groundwater loss, precipitation-runoff relationship, hysteresis influence of human activity, and record of time series can seldom be satisfied for many watersheds, it is more realistic and practical to distinguish relative effects than to estimate absolute magnitudes of δ. Qc and δ. Qh. Moreover, a generic framework was presented for gauged watersheds with negligible groundwater loss, aiming to avoid misuse of the methods in practice. © 2014 Elsevier Ltd.

On September 11, 2008, the Chinese government announced a recall of infant milk powder that was tainted by melamine, a chemical usually used in plastics. Consumption of melamine caused infants to develop kidney stones which, if left untreated, could cause renal failure and death. More than 290,000 people (most of them infant children) were poisoned and at least six babies are confirmed to have died from ingesting the melamine contaminated infant milk powder. The Chinese government imposed very high penalties on people and companies involved in the melamine scandal, including lifetime prison sentences and even executions. The problems in China's dairy industry were a result of rapid growth fueled by large investments from multinational dairy firms, development of a highly modern and concentrated processing sector that obtained its raw materials from millions of small, poor and uneducated traditional farmers and government support and encouragement for growth but with little emphasis on inspection and safety issues. The melamine crisis prompted the Chinese government to bring in a new food safety law, mandate regular inspections of all companies involved in the food business with no exemptions and set new allowable tolerances for melamine in dairy products. © 2010 Elsevier Ltd.

To study the anti-inflammatory mechanism of geniposide and observe the effect of geniposide on the expression of Toll-like receptor 4 (TLR4), the activity of NF-κB, and the release of pro-inflammatory cytokines- TNF-α, IL-1, and IL-6-in the RAW264.7 macrophages treated with lipopolysaccharide (LPS). There were three experimental groups, including the control group, LPS group and LPS combined with geniposide group in this study. RAW264.7 macrophage cells were treated with LPS to induce cellular inflammation. Cell proliferation was measured by CCK-8. The concentrations of TNF-α, IL-1, and IL-6 in cell culture media were measured by ELISA. mRNA levels of TLR4 and P65 were examined by real-time PCR. The protein levels of p-IκB, P65, p-P65 and TLR4 were detected by Western blotting. Geniposide had no effect on cell proliferation. However, geniposide down-regulated the expression of TNF-α, IL-1, and IL-6, and also inhibited the expression of TLR4 and the activity of NF-κB. Geniposide exerts its anti-inflammatory effect through inhibiting the activity of NF-κB in the TLR4-NF-κB pathway in macrophages.
