Haze has become an important topic for discussion in relation to global atmospheric pollution prevention and control due to its environmental and health effects. In order to explore the change in the space-time pattern of haze in the Yangtze River Delta of China and the associated human health losses, this paper uses MODIS Level 2 aerosol products of 2000-14 as well as applying the Kriging interpolation method to analyze the characteristics of changes of aerosol optical depth (AOD). The human capital method is then applied to evaluate the health losses caused by haze pollution in 2004-13. The research proves that in the latest 15 years, the AOD in the Yangtze River Delta has fluctuately risen from 0.5645 in 2000 to 0.5841 in 2014, with the spatial distribution pattern higher in the north and lower in the south. The northern cities of Shanghai, the southern part of Jiangsu Province, and the Hangzhou Bay region have always registered highest values. This analysis also shows that elevated concentration has gradually spread toward the southern areas. Meanwhile, the health losses in the whole region and each city have tended to be aggravated; the health losses in southern cities are far lower than those in northern cities. For example, the southern cities of Zhoushan and Taizhou see the lowest health losses ($0.039 billion and $0.035 billion, respectively). Conversely, the highest health losses are located in the northern cities of Shanghai, at $13.60 billion. However, the growth rate of health losses in southern cities is obviously higher than that in northern cities as a result of pollution transfer at the average rates of 249.18% and 99.94%.

Background: Early life adversity (ELA) is not uncommon in major depressive disorder (MDD) patients. Childhood trauma has been reported more frequently in adult MDD patients relative to healthy controls. Recent researches have demonstrated that ELA could result in changes in brain morphology which might be an aetiological factor of MDD development. Materials and methods: We recruited 40 young adult patients suffered from MDD and made computed tomography scan. Subjects were divided in two groups: MDD patients with ELA experience (E+D) vs. MDD patients without ELA experience (E–D) according to Chinese version-Childhood Trauma Questionnaire (CTQ). 17-item Hamilton Depression (HAMD) Scale and Neuropsychiatric Inventory (NPI) were also examined. Student’s t-test was used to compare the HAMD scores, NPI scores, CTQ subcomponents scores, third ventricular (TV) width and volume of patients from E+D and E–D groups. Results: Findings demonstrated that ELA might result in TV enlargement; furthermore, there was a correlation between physical neglect and TV volume. Conclusions: These findings supported the hypothesis that ELA could induce changes of structure around the TV, which might undermine the aetiology of MDD. (Folia Morphol 2018; 77, 3: 428–433)

The Chinese government has made a commitment to achieve a 60-65% reduction of CO2 emissions by 2030 compared with that in 2005. Most provinces are assigned differentiated reduction tasks due to different natural resources endowment, energy consumption structure, and economic developments. Marginal abatement cost (MAC) supplies cost information on regional pollutant reduction processes and should be an important evaluation indicator of policies. In this study, we build a quadratic parametric directional distance function (DDF) to estimate provincial MAC of CO2 emissions in China during 2000-2015. Linear programming is used to solve the parameter estimation problem. Results are as follows: 1) LP method supplies efficient parameter estimation results and obtains 98.33% reliable MACs during the research period. 2) MAC keeps a growing trend for most provinces in 2000-2015. Especially when China enters the New Normal stage in 2012, this growing trend has been accelerated. These trends reveal that MAC gradually becomes a more important indicator to evaluate emission reduction measurements. 3) From a spatial distribution aspect, positive cluster feature has experienced such fluctuations as “apparent rise→significant decline→close to zero.” In this stage, their spatial cluster is close to random distribution state. Spatial heterogeneity turns to being enlarged, especially among provinces at higher MAC range. These evolutionary trends will have important influence on their carbon reduction measure implementing process. Eastern regions should turn more focus on low-carbon technology innovation to push their lowcarbon transformation. For middle and western regions, they should promote their production efficiencyand obtain more technology spillovers from eastern provinces in the future to stimulate their economic growth and low-carbon transformation.

Differentiated carbon dioxide emission reduction targets and optimizing industrial incentive policy is an important subject in China’s low-carbon economic transformation. With the application of the environmental input-output (EIO) method and the bi-proportional scaling updating schedule, the inter-industrial inputoutput tables in 2017 are forecasted and then carbon dioxide emissions of 30 industrial sectors are simulated in seven scenarios. Based on these results, conclusions are: 1. Twenty-five high carbon dioxide emission sectors among 30 national sectors are divided into three types. Five sectors are whole-process high carbon dioxide emission type, 18 are conductive type, and two are apparent high type. 2. Final demands keep the dominant role in pushing sectorial emissions growing, whether in total carbon dioxide emission intensity or emission quantities. Technical progress leads to emissions declines in intensity and quantity. Moreover, special energy-saving technical progress will gradually exceed universal technical progress in reduction effects. Whole-process high carbon sectors are the best selection to gain favorable incentive policies to promote carbon dioxide emissions reduction. Apparent high carbon sectors are in last place. 3. With incentive policies being improved, technical progress reduction effect is increasing. However, it is not enough to offset the driving effect from final demands growing in seven scenarios. More favorable incentives and investments should be allocated into high emission sectors, especially into the most sensitive ones.

Pollution of the marine environment by ship garbage is an urgent problem to be solved at home and abroad. The ship kitchen garbage vacuum collection system is a new environmental protection scheme for garbage disposal. It has many advantages, such as using a pipeline instead of manual operation, creating high-level sanitary conditions, realising completely closed garbage collection and transportation, eliminating cross-pollution, saving space and so on. In this paper, the system is modelled, and the calculation of pipeline pressure loss, the vacuum degree of the vacuum tank and the energy consumption of the system are briefly introduced. In order to reduce the energy consumption, an algorithm for the emptying and discharging port is presented. In order to solve the problem of optimising relevant parameters, the vacuum transport mechanism of garbage is studied based on an optimisation model of the pipe network, and the experimental platform of a simulation device is set up. In engineering, this is of great significance to the design of cruise ship garbage collection and treatment systems and the development of supporting technology

The effect of exogenous applied nitric oxide on photosynthesis under heat stress was investigated in rice seedlings. High temperature resulted in significant reductions of the net photosynthetic rate (P N) due to non-stomatal components. Application of nitric oxide donors, sodium nitroprusside (SNP) or S-nitrosoglutathione (GSNO), dramatically alleviated the decrease of P N induced by high temperature. Chlorophyll fluorescence measurement revealed that high temperature caused significant increase of the initial fluorescence (F o) and non-photochemical quenching (NPQ) whereas remarkable decrease of the maximal fluorescence (F m), the maximal efficiency of PSII photochemistry (F v/F m), the actual PSII efficiency (ΦPSII), and photochemical quenching (q p). In the presence of SNP or GSNO pretreatment, the increase of F o and decrease of F m, F v/F m, ΦPSII and q p were markedly mitigated, but NPQ was further elevated. Moreover, with SNP or GSNO pretreatment, H2O2 accumulation and electrolyte leakage induced by heat treatment were significantly reduced, whereas zeaxanthin content and carotenoid content relative to chlorophyll were elevated. The potassium salt of 2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (cPTIO), a specific NO scavenger, arrested NO donors mediated effects. These results suggest that NO can effectively protect photosynthesis from damage induced by heat stress. The activation effect of NO on photosynthesis may be mediated by acting as ROS scavenging, or/and alleviating oxidative stress via maintaining higher carotenoid content relative to chlorophyll or/and enhancing thermal dissipation of excess energy through keeping higher level of zeaxanthin content under heat stress.

Oujiang Estuary is a complex tidal estuary with many channels and shoals in the East China Sea, which was affected by typhoon frequently. The navigation channel of Wenzhou Port is located in the north branch of Oujiang Estuary, which happened serious sediment siltation in many times due to typhoon impact. The regulation is considered to decrease siltaion of the channel and protect shoals as well. According to the site survey data, the mathematic model is established and validated, which simulates the hydrodynamic, sediment transport and channel siltation due to typhoon in Oujiang Estuary. The channel regulation scenario is studied by the model simulation after analysis of the silation character. It indicates that the high concentration sediment from shoals north of channel is main sediment source caused siltation in the channel, which can be prevented into the channel by the regulation scenario and decrease siltation efficiently

Understanding composition, structure and spatial heterogeneity in soil seed banks is important for the management of grassland ecosystem. Although the effect of fencing and grazing on vegetation composition is widely known, information on species composition, seed density and spatial heterogeneity of soil seed banks in sandy grasslands under fencing and grazing is still lacking. We measured the species composition and seed density of soil seed banks in fenced grassland, grazed grassland and grazed shrubby grassland in Horqin Sand Land, Northern China. By applying the geostatistical methods, we assessed how fencing and grazing affected spatial heterogeneity of soil seed banks in sandy grasslands. Total seed density and species richness in soil seed banks were lower in fenced grassland than in either grazed grassland or grazed shrubby grassland. Seed density and species richness of annual species in soil seed banks were also lower in fenced grassland than in either grazed grassland or grazed shrubby grassland, while those of perennial species showed a reverse trend. The analysis of spatial autocorrelation ranges, fractal dimensions and distribution pattern maps from geostatistical methods showed that spatial heterogeneity of seed density and species richness in soil seed banks were also lower in fenced grassland than in either grazed grassland or grazed shrubby grassland. Continuous fencing increases the seed density and species richness of perennial species in soil seed banks, as well as results in a decrease in spatial heterogeneity of seed density and species richness in soil seed banks. So, continuous fencing should be considered to restore the degraded sandy grasslands in management of semiarid grassland ecosystems.

The concentrations of catalpol in the culture solutions, roots, stems and leaves of Rehmannia glutinosa Libosch. were determined by HPLC. The biological activity of catalpol was detected with Arabidopsis thaliana L. seedlings. The results showed that all R. glutinosa Libosch. vegetative organs contained catalpol. Catalpol was also found in culture solutions in which the R. glutinosa Libosch. seedlings were grown. Catalpol inhibited seed germination and root growth in A. thaliana L., respectively, at concentration 80 and 20 µmol/dm³. These results suggest that R. glutinosa Libosch. may produce catalpol and secrete it into the culture solutions. Catalpol acts as an antimicrobial and allelopathic agent; the secretion of catalpol into the R. glutinosa Libosch. rhizosphere may provide a competitive advantage for root establishment through local suppression of soil microorganisms and inhibition of the growth of competing plant species. However, autotoxicity of catalpol in R. glutinosa Libosch. may occur, which may be relevant to the obstacle in its continuous cropping.

The effect of sodium nitroprusside (SNP; nitric oxide donor) treatment on wheat plant (Triticum aestivum L.) under drought stress during grain filling stage was investigated. When two cultivars wheat plants, Yumai No. 949 and Shanmai No. 5, were drought stressed by PEG for 72 h and rewatered for 48 h, the affections of osmotic dehydration and rehydration on the antioxidant enzymes activities and psbA gene transcriptional abundance were compared. Relative water contents (RWC) decreased markedly after 72 h of PEG stress, along with an obvious decrease in chlorophyll content, increase in SOD, CAT and APX activities, and MDA content as well. Real-time quantitative polymerase chain amplification indicated that drought stress also remarkably inhibited the transcription of psbA gene in photosystem II (PSII). All of these responses could be restored by removing of stress and applying another 48 h of rewatering. The exogenous 0.2 mmol l⁻¹ SNP treatment could significantly alleviate the stress injury and accelerate the progress of recovery. Compared to Yumai No. 949, Shanmai No. 5 had less destroyed plasma membranes, higher RWC and chlorophyll contents, more psbA gene transcriptional abundance during water stress, and rapider recovery to control after rewatering, suggesting not only a better drought resistance but also a better recovery capability after a severe drought stress. The present results also suggested that the application of exogenous SNP could enhance the stress resistance of wheat plant during grain filling stage by increasing antioxidant enzymes activities, as well as protecting important gene transcription in PSII, which were to the benefit of functional recovery from drought stress.

The objective of this study was to determine and compare the effect of five different pretreatments including sulfite treatment (ST), osmotic dehydration (OD), steam blanching (SB), s team blanching plus osmotic dehydration (SB+OD), and ultrasound treatment (UT), on the microwave vacuum drying (MVD) kinetics, the physicochemical properties, and sensory quality of the apple slices. The results showed that the p retreatments prior to MVD could reduce the drying time of apple slices by 25–45% as compared to the non-pretreated apple slices, and the drying time in the SB+OD apple slices sample was shortest. Whether pretreated or not, MVD process was controlled by diffusion and characterized by a two-stage falling-rate drying. As calculated according to the Fick’s law of diffusion, the moisture diffusivities (Deff) ranged from 1.64×10¯⁸ to 3.46×10¯⁸ m2 /s. Different pretreatment methods had a signifi cant infl uence on the physicochemical properties and sensory qualities of the dried products (p<0.05). The SB+OD-pretreated apple slices showed the lowest shrinkage (59.5%) and the highest total sugar content (77.90 g/100 g dry matter). Besides, the OD-pretreated apple slices showed the highest density (0.953 g/cm3 ) and the lowest titratable acidity (1.67 g/100 g dry matter). In addition, the ST-pretreated samples showed the highest titratable acidity (3.21 g/100 g dry matter) and vitamin C content (12.74 mg/100 g dry matter), while the sample pretreated by SB showed the highest total phenolics content (18.37 mg/g dry matter). Non-sulfi te-pretreated samples were superior to the sulfi te treatment or the control in flavor but inferior to the sulfi te treatment in color. Results of preference sensory evaluation showed that the dried apple slices were preferred by the panelists in the following order: SB+OD>SB>UT>OD>ST>the control.

Whereas strong antioxidant properties of spermine have been reported mostly in in vitro studies, there is lack of the in vivo studies on spermine influence conducted on mammals. The main objective of this study was to investigate the effects of different doses of spermine and the period of its supplementation on the liver and spleen antioxidant capacity in weaned rats. Male Sprague-Dawley rats at the age of 19 days received intragastrically spermine at the dose of 0.2 or 0.4 μmol · g-1 body weight for 3 or 7 days, respectively. Control rats received saline in analogical way. It was found that liver anti-superoxide anion (ASA) capacity, catalase (CAT) activity, glutathione (GSH) content and total antioxidant capacity (T-AOC) were increased in group supplemented with higher dose of spermine after 3 days, and anti-hydroxy radical (AHR) capacity was increased when treatment lasted for 7 days. In the spleen the higher spermine dose supplementation increased ASA capacity and total superoxide dismutase (T-SOD) activity (after 3 and 7 days), AHR capacity (after 7 days) and T-AOC (after 3 days) in comparison to the corresponding control groups (P < 0.05). Only in the spleen the lower spermine dose reduced lipid peroxidation level and increased CAT activity and GSH content regardless treatment duration (P < 0.05). The obtained results suggest that spermine supplementation can improve the antioxidant properties of the liver and spleen of weaned rats in a dose-, time- and tissue-dependent manner.

Although the Qinghai-Tibetan Plateau (QTP) has experienced striking warming during the past century, information on how soil carbon (C) and nitrogen (N) pools of the alpine regions on the QTP respond to long-term warming is scarce. The aims of this study were to assess the response of soil organic C (SOC), total N (TN), labile C and N – including microbial biomass C (MBC) and N (MBN), inorganic N (Ninorg), dissolved organic C (DOC), and N (DON) – to 15-year experimental warming in an alpine region (Kobresia meadow and Potentilla scrubland), on the northeastern QTP using open-top chambers (OTCs). Fifteen-year experimental warming had no effect on SOC and TN concentrations and storage at 0-30 cm soil depth, either in Kobresia meadow or Potentilla scrubland habitat, which might be related to the low temperature increase and the unchanged water content. Long-term warming obviously affected soil labile C and N and their contributions to SOC and TN, especially in the meadow habitat, but the values were low, thus the variation of the labile C and N was not enough to influence total C and N storage. The C and N pools were shown to be controlled by different controlling factors, and scrubland was more stable than the meadow ecosystem confronting the change of environment.

Wheat (Triticum aestivum) plants often suffer from heat stress combined with high irradiance during the grain filling stage. Glycine betaine (GB) is a compatible solute that accumulates rapidly to enhance stress tolerance in wheat under abiotic stress. In this study, the effect of foliar application of GB on photosystem II (PSII) photochemistry in wheat leaves under the heat and high light stresses were investigated. The results showed that GB-supplemented wheat plants maintained higher chlorophyll content, photochemical activity of PSII and net photosynthetic rate (Pn) than stressed only plants. Moreover, GB-treated plants could retard the decrease of psbA gene transcription and accelerate the endogenous accumulation of GB in leaves. The results suggested that the increasing stress tolerance by GB accumulation was associated with an improvement in D1 protein synthesis, which accelerated the repair of PSII following stress-enhanced photoinhibition. Moreover, the accumulation of abscisic acid under the heat and high light stresses was retarded by foliar application of GB, and the decrease of stomatal conductance was inhibited as well. The results suggested that GB accumulation in vivo was involved in the regulation of stomatal conductance. Further work is required to elucidate the mechanism of GB-induced stomatal movement and PSII photoprotection.
