Drought risk assessment of China’s mid-season paddy
Yongdeng Lei,Jingai Wang,Lili Luo
International Journal of Disaster Risk Science , 2011, DOI: 10.1007/s13753-011-0009-4
Abstract: China has the world’s largest population and a large and critically important agricultural sector. Sixty-five percent of the Chinese population lives on paddy rice. However, drought disasters frequently afflict China’s rural population and threate n its food security. It is therefore of paramount importance to assess the drought risk of paddy in China. We establish a quantitative risk assessment model for the drought risk of mid-season paddy and regional-specific vulnerability curves, evaluate the drought risk of mid-season paddy, and compile a series of risk maps. The drought disaster risk rating results indicate that risk is highest in Northeast China, followed by Northwest China, North China, and South China, showing a decreasing trend from north to south. The mid-season paddy area of Northeast China has the highest mean risk index (0.58–0.71), followed by northwestern provinces such as Inner Mongolia and Xinjiang (0.5–0.6), while risk indices in provinces of North China such as Hebei and Shandong range from 0.3–0.5, and the southern provinces show a relatively low level of risk. This article presents the preliminary results of a scientific inquiry on where the high drought risk areas of mid-season paddy are and how high the risk is. These results provide a regional-specific basis for drought risk governance of paddy in China.

Abstract: Context: Broussonetia papyrifera (L.) Vent. (Moraceae), a traditional Chinese medicinal herb, has been extensively applied for many years to treat various diseases. Its fruits (Fructus Broussonetiae) have been commonly used as an important tonic for the treatment of age-related disorders with long history; recent research has proved that it contains 32% to 35% fixed oils. The fixed oil is composed mainly of unsaturated fatty acids, including linoleic acid, methyl palmitate, oleic acid and linoleic acid ester. Objective: To investigate the chemistry of the fatty oil from Fructus Broussonetiae (FOFB) and its effects on plasma lipids. Methods: The chemical composition of FOFB was examined and identified by GC-MS. Thirty male Wistar rats fed diet containing FOFB and cholesterol were studied for 28 days. The effect of dietary FOFB on plasma lipids and adipose tissue was tested. Results: Twelve compounds of FOFB were examined and identified, the major components of fatty oil, 8,11-octadecadienoic acid (83.75%), palmitic acid (10.22%), octadecadienoic acid (2.97%) and 9-octadecenoic acid (1.69%) were found. FOFB significantly exhibited the activities of decreasing the rat adipose tissue weight, triacylglycerol, total cholesterol, and low-density lipoprotein cholesterol (LDL-C) concentrations while the rat body weight remained unchanged. Discussion: FOFB contained a large amount of PUFA which had the effect on reducing plasma lipids and adipose.

Abstract: Tat protein, released by HIV-infected cells, has a battery of important biological effects leading to distinct AIDS-associated pathologies. Cell surface heparan sulfate protoglycans (HSPGs) have been accepted as endogenous Tat receptors, and the Tat basic domain has been identified as the heparin binding site. However, findings that deletion or substitution of the basic domain inhibits but does not completely eliminate Tat–heparin interactions suggest that the basic domain is not the sole Tat heparin binding site. In the current study, an approach integrating computational modeling, mutagenesis, biophysical and cell-based assays was used to elucidate a novel, high affinity heparin-binding site: a Lys12, Lys41, Arg78 (KKR) spatial domain. This domain was also found to facilitate Tat-driven β1 integrin activation, producing subsequent SLK cell adhesion in an HSPG-dependent manner, but was not involved in Tat internalization. The identification of this new heparin binding site may foster further insight into the nature of Tat-heparin interactions and subsequent biological functions, facilitating the rational design of new therapeutics against Tat-mediated pathological events.

Abstract: Infantile spasms is an age-specific epileptic syndrome associated with poor developmental outcomes and poor response to nearly all traditional antiepileptic drugs except adrenocorticotropic hormone (ACTH). We investigated the protective mechanism of ACTH against brain damage. An infantile spasm rat model induced by N-methyl-d-aspartate (NMDA) in neonate rats was used. Pregnant rats were randomly divided into the stress-exposed and the non-stress exposed groups, and their offspring were randomly divided into ACTH-treated spasm model, untreated spasm model, and control groups. A proteomics-based approach was used to detect the proteome differences between ACTH-treated and untreated groups. Gel image analysis was followed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometric protein identification and bioinformatics analysis. Prenatal stress exposure resulted in more severe seizures, and ACTH treatment reduced and delayed the onset of seizures. The most significantly up-regulated proteins included isoform 1 of tubulin β-5 chain, cofilin-1 (CFL1), synaptosomal-associated protein 25, malate dehydrogenase, N(G),N(G)-dimethylarginine dimethylaminohydrolase 1, annexin A3 (ANXA3), and rho GDP-dissociation inhibitor 1 (ARHGDIA). In contrast, tubulin α-1A chain was down-regulated. Three of the identified proteins, ARHGDIA, ANXA3, and CFL1, were validated using western blot analysis. ARHGDIA expression was assayed in the brain samples of five infantile spasm patients. These proteins are involved in the cytoskeleton, synapses, energy metabolism, vascular regulation, signal transduction, and acetylation. The mechanism underlying the effects of ACTH involves the molecular events affected by these proteins, and protein acetylation is the mechanism of action of the drug treatment.

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0011926
Abstract: Clear, transparent and sufficiently detailed abstracts of randomized trials (RCTs), published in journal articles are important because readers will often base their initial assessment of a trial on such information. However, little is known about the quality of reporting in abstracts of RCTs published in medical journals in China.

Abstract: China has been frequently and heavily affected by drought disasters. During 2009–2010, three large-scale severe droughts struck China, caused considerable social, economic, and ecological losses. These droughts showed significant regional differences. This study employs a two-stage transition framework comprising “entry” and “exit” transitions to discuss disaster risk management of drought in China, by taking the three droughts as comparative case studies. Chinese society’s response in the exit transition is examined and the underlying factors that enable the entry trigger are diagnosed. The policy responses that lead to the exit transition from these drought disasters were appropriate, but there is substantial room for improvement in management strategy regarding both entry and exit transitions. This article suggests that government policies should emphasize entry-prevention measures that reduce adverse impacts early in a drought episode rather than focus solely on improving performance in achieving a rapid exit transition from drought.

Abstract: The effect of light intensity on asexual reproduction of Cyanea nozakii Kishinouye was investigated. Relative growth rate, specific growth rate of scyphistomae and scyphistomae cysts reproductive rate exposed to 400 lx were significantly higher than those exposed to other treatments (P<0.05). The result was 400 lx > 800 lx > 1200 lx > 0 lx. The occurrence of scyphistomae cysts reproduction delayed as the light intensity decreased from 400 lx to 0 lx. Podocyst germination rate was highest in 800 lx, and no significant difference was observed among different groups (P>0.05). The strobilation rate was highest in 400 lx and lowest in 0 lx during the experiment. Suitable light intensity might accelerate the growth, scyphistomae cysts reproduction, and strobilation.
