Abstract
Self-absorption and unknown transition probabilities of the analytical lines hinder the accurate quantitative elemental analysis of bismuth brass with conventional calibration-free laser-induced breakdown spectroscopy (LIBS). In this work, target-enhanced orthogonal double-pulse LIBS combined with a variant one-point calibration method was used to solve this problem and realize quantitative elemental analysis of bismuth brass with a relative error of less than 4%. This approach is able to reduce the influence of self-absorption and capable of using analytical lines with unknown transition probabilities while using a calibration-free algorithm, which is helpful for accurate quantitative elemental analysis of bismuth brass and other samples.

Abstract
Reactor neutrino experiments play a crucial role in advancing our knowledge of neutrinos. In this Letter, the evolution of the flux and spectrum as a function of the reactor isotopic content is reported in terms of the inverse-beta-decay yield at Daya Bay with 1958 days of data and improved systematic uncertainties. These measurements are compared with two signature model predictions: the Huber-Mueller model based on the conversion method and the SM2018 model based on the summation method. The measured average flux and spectrum, as well as the flux evolution with the ^{239}Pu isotopic fraction, are inconsistent with the predictions of the Huber-Mueller model. In contrast, the SM2018 model is shown to agree with the average flux and its evolution but fails to describe the energy spectrum. Altering the predicted inverse-beta-decay spectrum from ^{239}Pu fission does not improve the agreement with the measurement for either model. The models can be brought into better agreement with the measurements if either the predicted spectrum due to ^{235}U fission is changed or the predicted ^{235}U, ^{238}U, ^{239}Pu, and ^{241}Pu spectra are changed in equal measure.

Abstract
A magnetic activated carbon adsorbent named NiFe2O4@AC was synthesized by modifying activated carbon with NiFe2O4 and used for the adsorption of Cr(Ⅵ) ions from waste water. The influencing factors, adsorption kinetics, and adsorption isotherms of Cr(Ⅵ) adsorption by the adsorbent were investigated. The results showed that the removal rate of Cr(Ⅵ) adsorption by NiFe2O4@AC reached 96.92%, and the adsorption amount reached 72.62 mg·g-1 at the adsorption conditions of temperature (298 K), pH 2, Cr(Ⅵ) initial concentration (150 mg·L-1), adsorbent dosage (0.1 g), and contact time (720 min). The experimental data were best described by the proposed secondary kinetics and Langmuir model, indicating that the adsorption process was a monolayer chemisorption process. The increase in temperature favored the adsorption of Cr(Ⅵ) on NiFe2O4@AC because the adsorption process was a spontaneous, heat-absorbing reaction. The adsorption mechanism of NiFe2O4@AC was mainly through complexation and electrostatic attraction to adsorb Cr(Ⅵ); meanwhile, the applied magnetic field could be separated from the solution, which has good application prospects.

Abstract
We present a new determination of the smallest neutrino mixing angle θ_{13} and the mass-squared difference Δm_{32}^{2} using a final sample of 5.55×10^{6} inverse beta-decay (IBD) candidates with the final-state neutron captured on gadolinium. This sample is selected from the complete dataset obtained by the Daya Bay reactor neutrino experiment in 3158 days of operation. Compared to the previous Daya Bay results, selection of IBD candidates has been optimized, energy calibration refined, and treatment of backgrounds further improved. The resulting oscillation parameters are sin^{2}2θ_{13}=0.0851±0.0024, Δm_{32}^{2}=(2.466±0.060)×10^{-3} eV^{2} for the normal mass ordering or Δm_{32}^{2}=-(2.571±0.060)×10^{-3} eV^{2} for the inverted mass ordering.

Abstract
Based on the crop yield data of China and each region from 1981 to 2020 (excluding data from Hong Kong, Macao, and Taiwan), by using the grain-straw ratio method, this study estimated the total amount of crop straw and collectable amount of crops, including corn, rice, wheat, other cereals, cotton, rapeseeds, peanuts, beans, tubers, sesame, fiber crops, sugarcane, and beetroots, and the spatial and temporal distribution characteristics of resource density and per capita resources of crop straw were analyzed. This study analyzed the current utilization mode, development, and change of crop straw in China. Finally, we used the life circle assessment (LCA) method to estimate the carbon emission reduction potential of biochar prepared from crop straw. The main findings were:from 1981 to 2020, the temporal distribution trend of theoretical crop straw resources and collectable straw resources in China generally showed a steady growth trend, and the two increased from 3.33×108 t and 3.04×108 t in 1981 to the highest values of 7.70×108 t and 6.63×108 t in 2020, with a net increase of 4.37×108 t and 3.59×108 t, respectively. The net increase in rice, wheat, and corn straw resources was 3.69×108t, accounting for between 77% and 85% of the total crop straw and always occupying the main position of straw resources in China. The proportion of wheat straw in the total amount of straw was maintained at approximately 20%, rice straw resources decreased from 44% to 28.4%, and corn straw increased from 19.9% to 34.2% from 1981 to 2020. In 2020, the total theoretical resources of crop straw in China were 7.72×108 t, and the source structures were:rice 28.4%, wheat 21.45%, corn 31.45%, other cereals 1.4%, beans 3.4%, tubers 0.82%, cotton 2.28%, peanuts 2.97%, rapeseeds 3.4%, sesame 0.12%, fiber crops 0.06%, beetroots 0.67%, and sugarcane 0.84%. As to the spatial distribution of crop straw resources in China in 2020, the locations with straw resources ≥ 60 million tons included Heilongjiang, Henan, and Shandong, of which Henan had as much as 88.56 million tons; those with between 40 million and 60 million tons included Hebei, Inner Mongolia, Jiangsu, and Anhui; those with between 20 million and 40 million tons included Liaoning, Jilin, Jiangxi, Hubei, Hunan, Sichuan, Yunnan, and Xinjiang; and the straw resources in the rest of the region were below 20 million tons. Rice straw was mostly distributed in the middle and lower reaches of the Yangtze River and the Northeast region, of which the amount of Heilongjiang rice straw was the largest, with 31.86 million tons; wheat straw was mainly distributed in North China, with Henan having the most abundant resources (48.04 million tons). Corn straw was mainly distributed in Northeast China and North China, of which Heilongjiang and Inner Mongolia corn straw resources were relatively rich, with 33.18 million tons and 29.90 million tons, respectively. Crop straw resource density and per capita resources were shared in 2020 in China. The average density of crop straw resources in China was 4.61 t·hm-2, and the average densities of crop straw resources in various agricultural areas were 5.39 t·hm-2 in Northeast China, 5.42 t·hm-2 in North China, 4.45 t·hm-2 in the Mengxin Region, 4.44 t·hm-2 in the middle and lower reaches of the Yangtze River, 3.92 t·hm-2in Tibet, 3.40 t·hm-2 in the Loess Plateau, 3.08 t·hm-2 in South China, and 2.91 t·hm-2 in Southwest China. The average per capita share of straw resources was 0.55 t. The average values of per capita straw resources in each region were:1.46 t in the Northeast area, 1.20 t in the Mengxin Region, 0.47 t in North China, 0.44 t in the middle and lower reaches of the Yangtze River, 0.40 t in the Loess Plateau, 0.37 t in the Southwest area, 0.33 t in the Qinghai-Tibet area, and 0.20 t in the South China area. The utilization of crop straw in China was diversified. Fertilizer and feed were the main utilizations, accounting for 62.1% and 15.4%, respectively. In 2020, collectable crop straw resources for the preparation of biochar totaled 2.04×108 t in China. Renewable energy replaced fossil fuels in the process of preparing biochar, which could reduce CO2e(CO2e:CO2 equivalent) emissions by 1.45×108 t. Biochar could sequester approximately 4.63×108 t of CO2e; biochar application was able to reduce chemical fertilizer application to achieve a CO2 emission reduction of 8.58×105 t; and biochar application could promote crop yield in order to reduce CO2e emissions by approximately 7.77×106 t. The inhibition of N2, respectively. In the process of biochar preparation and application, the total greenhouse gas emission was 3.32×107 t, and the net greenhouse effect emission reduction reached 5.86×108 t, i.e., it could sequester 0.88 t CO2e per ton of raw materials. The net greenhouse gas emission reduction of unused straw was 6.73×107 t in 2020. With the continuous harvest of grain crops in China, the potential of biochar preparation and carbon sequestration will increase yearly. Using crop straw to prepare biochar has great potential and will be one of the most effective ways to achieve carbon emission reduction in agriculture. It is suggested that government departments should pay attention to the preparation of biochar, support the field experiments of biochar application effects after applying soil on policy and funds, and then introduce relevant biochar standards to ensure the scientific application of biochar prepared by crop straw according to local conditions, so as to achieve the dual benefits of carbon emission reduction and soil remediation and yield increase.

Abstract
Objective: To investigate the efficacy and safety of liver venous deprivation (LVD) before secondary resection of primary liver cancer. Methods: 56 patients with advanced primary liver cancer who were not suitable for primary resection in Liver Surgery Department of Xinxiang Central Hospital from January 2018 to January 2019 were analyzed retrospectively. They were divided into liver vein deprivation group (LVD group: LVD+ PVE, n=26) and portal vein embolization group (PVE group, n=30). The dynamic changes of liver reserve function and future liver remnant volume (FLR-V), R0 resection rate, surgical complications, postoperative recurrence rate and overall survival rate of two groups before and after LVD/PVE were compared. Results: The success rate of puncture and embolization in LVD group and PVE group was 100%. There were no grade Ⅳ complications, and there was no significant difference of grades Ⅰ, Ⅱ and Ⅲ complications between the groups (P=0.808). The FLR-V of LVD group before embolization, 7, 14 and 21 days after embolization was (493.1±25.8), (673.2±56.1), (779.5±81.6) and (853.3±85.2) cm(3), respectively. The FLR-V of PVE group before embolization, 7, 14 and 21 days after embolization were (502.4±20.1), (688.6±43.9), (656.8±73.7) and (563.5±69.1) cm(3), respectively. There was no significant difference in FLR-V between the two groups before and 7 days after embolization (P>0.05). The FLR-V of LVD group was higher than that of PVE group at 14 and 21 days after embolization (P<0.01). The preparation time of LVD group was (20.4±6.3) days, which was shorter than that of PVE group [(31.5±8.8) days, P=0.045]. The rate of secondary hepatectomy was 92.3% (24/26), which was higher than that of PVE group [70.0% (21/30), P=0.036]. The R0 resection rate was 87.5% (21/24), which was higher than that of the PVE group [57.1% (12/21), P=0.022]. However, there were no significant differences in surgical methods, operation time, intraoperative blood loss, Clavien-Dindo complication grade and length of hospital stay between the two groups (P>0.05). After hepatectomy, the median recurrence time and median survival time of LVD group were 12.6 months and 21.3 months, respectively, which were longer than those of PVE group (9.4 months and 13.5 months, respectively, P<0.01). Conclusions: For patients with advanced liver cancer who are not suitable for primary hepatectomy, preoperative LVD can significantly increase FLR-V, improve the resection rate of secondary surgery, shorten the preparation time of two operations, and do not increase surgical complications. Moreover, patients with LVD can improve the R0 resection rate of secondary surgery. The postoperative recurrence time and overall survival rate of patients with LVD are better than those of patients with PVE, and LVD has a good long-term effect.

Abstract
This Letter reports the first measurement of high-energy reactor antineutrinos at Daya Bay, with nearly 9000 inverse beta decay candidates in the prompt energy region of 8-12 MeV observed over 1958 days of data collection. A multivariate analysis is used to separate 2500 signal events from background statistically. The hypothesis of no reactor antineutrinos with neutrino energy above 10 MeV is rejected with a significance of 6.2 standard deviations. A 29% antineutrino flux deficit in the prompt energy region of 8-11 MeV is observed compared to a recent model prediction. We provide the unfolded antineutrino spectrum above 7 MeV as a data-based reference for other experiments. This result provides the first direct observation of the production of antineutrinos from several high-Q_{β} isotopes in commercial reactors.

Abstract
Paracelsus, the first person in the history of modern Western medicine, specified to break the shackles of the traditional medical system thoroughly and revolutionise the classical medical system completely. He introduced traditional alchemy into medicine, and changed it from making gold into producing drugs which were helpful to human health. He believed that nature and human were made by God with "three principles" - sulphur, salt and hydrargyrum. He also believed that human body, as a "chemical system", was full of a variety of chemical reactions. His ideas brought a new worldview, a chemical one, to the medical field influenced by the concept of"Humorism" for ages. The chemical worldview laid the foundation for "iatrochemistry" and channelled a path for the following medical development. The "three principles" of Paracelsus did not surpass the "Humorism" proposed by Galen in terms of underlining the balance of human health. However, the idea, that the mineral substances in nature in the "three principles" could be taken as medicines to help the recovery of human body, broke through the traditional medical system proposed by Galen, offered valuable ideological resources and experience for the following expansion and development of medicines.

Abstract
Post anesthesia care units (PACU) are designed to handle the utilization of the operating rooms and provide a place for postoperative patients to recover consciousness. PACU first appeared in the 1940s, prevailed in the United States in the 1950s, and expanded gradually to Canada, South Africa and other places, and were popularized in the UK and other European countries in the 1960s. PACU were developed widely in China after 1990 and expanded rapidly after the 21st century. It is now taken as an assessment indicator for evaluating hospitals. A set of management systems for PACU was gradually regulated and established, such as anesthesia record sheets, equipment and personnel training in the process of PACU development. It is currently evolving towards centralization, economization and specialization.

Abstract
A joint determination of the reactor antineutrino spectra resulting from the fission of ^{235}U and ^{239}Pu has been carried out by the Daya Bay and PROSPECT Collaborations. This Letter reports the level of consistency of ^{235}U spectrum measurements from the two experiments and presents new results from a joint analysis of both data sets. The measurements are found to be consistent. The combined analysis reduces the degeneracy between the dominant ^{235}U and ^{239}Pu isotopes and improves the uncertainty of the ^{235}U spectral shape to about 3%. The ^{235}U and ^{239}Pu antineutrino energy spectra are unfolded from the jointly deconvolved reactor spectra using the Wiener-SVD unfolding method, providing a data-based reference for other reactor antineutrino experiments and other applications. This is the first measurement of the ^{235}U and ^{239}Pu spectra based on the combination of experiments at low- and highly enriched uranium reactors.

Abstract
Silibinin, one of the flavonoids isolated from milk thistle seeds of Silybum marianum, has hepatoprotective properties against toxins in clinical. However, the detailed mechanisms have remained unclear. This study investigates the underlying mechanism of silibinin in the protection against ethanol- or acetaldehyde-induced damage of neonatal mouse primary hepatocytes in vitro. The results show that ethanol inhibited proliferation of hepatocytes in a time (12, 24, 36 h) and dose-dependent (0-800 mM) manner. However, silibinin did not show protective effect on ethanol (500 mM)-induced suppression of hepatocyte proliferation. Acetaldehyde, the toxic metabolite of ethanol, appearing immediately in individuals after drink also inhibited the proliferation of hepatocytes in a dose-dependent (0-12 mM) manner. Surprisingly, silibinin significantly increased the cell viability and reduced the leakage of alanine amino transferase (ALT) and aspartate amino transferase (AST) in acetaldehyde-treated hepatocytes, suggesting that silibinin protected cell injury caused by acetaldehyde treatment. The apoptosis-inducing effect of acetaldehyde was demonstrated by the increased number of cells in sub-G1 phase as well as caspase-3 activation. Further study shows that acetaldehyde induced autophagy in the hepatocytes. The autophagy inhibitors, 3-Methyladenine (3-MA) and chloroquine (CQ), further decreased the viability of cells treated with acetaldehyde, suggesting that autophagy plays a protective role against apoptosis. Consistently, silibinin (20 μM) significantly reduced the activation of caspase 3 or apoptosis and increased the conversion of LC3-I to LC3-II or autophagy. Taken together, it is concluded that silibinin does not repress the ethanol- induced hepatocyte injury, whereas silibinin reduces acetaldehyde-caused hepatocyte injury through down-regulation of apoptosis and up-regulation of autophagy.

Abstract
BACKGROUND Reliable interfacing with peripheral nervous system is essential to extract neural signals. Current implantable peripheral nerve electrodes cannot provide long-term reliable interfaces due to their mechanical mismatch with host nerves. Carbon nanotube (CNT) yarns possess excellent mechanical flexibility and electrical conductivity. It is of great necessity to investigate the selectivity of implantable CNT yarn electrodes. NEW METHOD Neural interfaces were fabricated with CNT yarn electrodes insulated with Parylene-C. Acute recordings were carried out on tibial nerves of rats, and compound nerve action potentials (CNAPs) were electrically evoked by biphasic current stimulation of four toes. Spatiotemporal characteristics of neural activity and spatial selectivity of the electrodes, denoted by selectivity index (SI), were analyzed in detail. RESULTS Conduction velocities of sensory afferent fibers recorded by CNT yarn electrodes varied between 4.25 m/s and 37.56 m/s. The SI maxima for specific toes were between 0.55 and 0.99 across seven electrodes. SIs for different CNT yarn electrodes are significantly different among varied toes. COMPARISON WITH EXISTING METHODS Most single CNT yarn electrode with a ∼ 500 μm exposed length can be sensitive to one or two specific toes in rodent animals. While, it is only possible to discriminate two non-adjacent toes by multisite TIME electrodes. CONCLUSION Single CNT yarn electrode exposed ∼ 500 μm showed SI values for different toes comparable to a multisite TIME electrode, and had high spatial selectivity for one or two specific toes. The electrodes with cross section exposed could intend to be more sensitive to one specific toe.

Abstract
As a global biodiversity hotspot, the subtropical evergreen broadleaved forest (SEBF) in southern China is strongly influenced by the humid monsoon climate, with distinct hot-wet and cool-dry seasons. However, the hydraulic strategies of this forest are not well understood. Branch and leaf hydraulic safety margins (HSMbranch and HSMleaf, respectively), as well as seasonal changes in predawn and midday leaf water potential (Ψpd and Ψmd), stomatal conductance (Gs), leaf to sapwood area ratio (AL/AS) and turgor loss point (Ψtlp), were examined for woody species in a mature SEBF. For comparison, we compiled these traits of tropical dry forests (TDFs) and Mediterranean-type woodlands (MWs) from the literature because they experience a hot-dry season. We found that on average, SEBF showed larger HSMbranch and HSMleaf than TDF and MW. During the dry season, TDF and MW species displayed a significant decrease in Ψpd and Ψmd. However, SEBF species showed a slight decrease in Ψpd but an increase in Ψmd. Similar to TDF and MW species, Gs was substantially lower in the dry season for SEBF species, but this might be primarily because of the low atmospheric temperature (low vapor pressure deficit). On the other hand, AL/AS and Ψtlp were not significant different between seasons for any SEBF species. Most SEBF species had leaves that were more resistant to cavitation than branches. Additionally, species with stronger leaf-to-branch vulnerability segmentation tended to have smaller HSMleaf but larger HSMbranch. Our results suggest that SEBF is at low hydraulic risk under the current climate.

Abstract
Objective: To analyze the anxiety and depression status of coal miners and related influencing factors, and to provide justifications for occupational health protection. Methods: From April 2017 to June 2017, a total of 650 coal miners in a mining area in Shanxi, China were enrolled; The coal miners were evaluated for their anxiety and depression status using the Hamilton Anxiety Rating Scale (14 items) and the Hamilton Depression Rating Scale (17 items) , respectively. The related influencing factors for anxiety and depression of the coal miners were analyzed with nonparametric test, chi-square test, and logistic regression. Results: The incidence rates of anxiety and depression were 51.1% and 60.5%, respectively. As suggested by the scores and detection rates of anxiety and depression, males had significantly higher anxiety and depression scores than females (P<0.05) ; subjects in older-age groups and those working in shifts had significantly higher anxiety scores (P<0.05) ; subjects with higher education degrees and smokers had significantly higher depression scores (P<0.05) ; while subjects with longer length of service, those with poor sleep quality, and those working in the underground mines had both significantly higher anxiety and depression scores (P<0.05) . The detection rate of anxiety was significantly higher in subjects with a drinking habit than in those who did not drink (P<0.05) . The detection rate of depression was significantly higher in subjects with hypertension than in those with normal blood pressure (P<0.05) . A multivariate logistic regression analysis showed that work type and length of service were related to anxiety; gender and length of service were related to depression; length of service was positively correlated with both anxiety and depression. Conclusion: The anxiety and depression in coal miners and related influencing factors should be taken seriously. Gender, age, length of service, working in shifts, education degree, smoking, sleep quality, underground working environment, and hypertension may be risk factors for anxiety and depression in coal miners.

Abstract
BACKGROUND The extensive involvement of microRNAs (miRNAs) in the pathogenesis of psoriasis is well documented. However, little is known about the contribution of specific miRNAs to the prevalence of this disease. OBJECTIVES To explore the role of miR-145-5p in psoriasis. METHODS miRNA microarray analysis was performed in four patients with psoriasis and four controls. Quantitative reverse-transcriptase polymerase chain reaction and fluorescence in situ hybridization were used to identify the dysregulated miRNAs. Luciferase assays were performed to determine whether miR-145-5p targets mixed-lineage kinase (MLK)3. CCK-8 assay and Magnetic Luminex Assay were performed to measure cell proliferation and chemokine secretion. Western blot analysis was used to investigate the protein levels of MLK3 and its downstream effectors. Mouse models of psoriasis were established for in vivo experiments. RESULTS miR-145-5p was downregulated in psoriatic lesional skin. Luciferase assays showed that MLK3 is a direct target of miR-145-5p. Overexpression of miR-145-5p in normal human epidermal keratinocytes (NHEKs) suppressed cell proliferation and secretion of chemokines. In contrast, silencing miR-145-5p promoted NHEK proliferation and increased chemokine secretion. Silencing MLK3 abrogated miR-145-5p inhibitor-induced promotion of cell proliferation and chemokine expression. miR-145-5p regulates nuclear factor-κB and signal transducer and activator of transcription 3 by targeting MLK3. Delivery of agomiR-145-5p into the skin decreased epidermal hyperplasia and ameliorated psoriasis-like dermatitis. Delivery of antagomiR-145-5p led to the opposite effects. CONCLUSIONS Our findings indicate that miR-145-5p negatively regulates proliferation and chemokine secretion of NHEKs by targeting MLK3, and downregulation of miR-145-5p contributes to skin inflammation in psoriasis lesions.

Abstract
There has been a growing interest in soil replacement and in-situ stabilization techniques in recent years. Many techniques in the remediation of contaminated soils have been proven to be effective methods. In this study, lime and calcium phosphate were added to immobilize the heavy metals in contaminated soils. The long-term application potential of these techniques were evaluated by taking the demonstration project of the soil remediation in Tongguan of Shaanxi as the case study.The status of heavy metal contamination in the study area resulted from artisanal gold mining was discussed. The strategies of remediation and the evaluation of the remediation results including the safety of agricultural practices were also studied. The results showed that soil was seriously contaminated in the study area with Cd, Pb, and Hg, and the residue mining waste was the main source. The potential ecological risk index ranged from 668 to 10969, suggesting that all the samples posed a very strong ecological hazard. Based on the pollution status, the soil replacement method and stabilization method were applied. Acceptable remediation results were obtained with lower total metal content (except Cd) and decreased heavy metal availability. However, the metal content of agricultural products was higher than the permissible value according to GB 2762-2012, which means that agricultural practices pose risks on remediated soils. Soil replacement and stabilization would be practical techniques for heavy metal polluted soil remediation. However, a consecutive investigation should be conducted for the assurance of food safety.

Abstract
In order to realize surface elemental microanalysis of solid samples with submicron lateral resolution, laser-ablation (LA) combined with high sensitive laser-induced fluorescence (LIF) detection was investigated. A 532 nm or 266 nm nanosecond laser pulse with low pulse energy was used to realize submicron laser-ablation on the surface of a copper alloy, and LIF technique was used to sensitively detect a minor lead element in the ablated samples. ~344 nm and ~267 nm lateral resolutions could be achieved experimentally under 532 nm and 266 nm laser ablations under the current experimental condition, respectively. This demonstrated the feasibility of using a LA-LIF technique for surface elemental microanalysis of solid samples with submicron spatial resolution. The potentials of continually improving the spatial resolution of this technique to nanoscale were discussed.

Abstract
Leaf turgor loss point (πtlp) indicates the capacity of a plant to maintain cell turgor pressure during dehydration, which has been proven to be strongly predictive of the plant response to drought. In this study, we compiled a data set of πtlp for 1752 woody plant individuals belonging to 389 species from nine major woody biomes in China, along with reduced sample size of hydraulic and leaf carbon economics data. We aimed to investigate the variation of πtlp across biomes varying in water availability. We also tested two hypotheses: (i) πtlp predicts leaf hydraulic safety margins and (ii) it is correlated with leaf carbon economics traits. Our results showed that there was a positive relationship between πtlp and aridity index: biomes from humid regions had less negative values than those from arid regions. This supports the idea that πtlp may reflect drought tolerance at the scale of woody biomes. As expected, πtlp was significantly positively correlated with leaf hydraulic safety margins that varied significantly across biomes, indicating that this trait may be useful in modelling changes of forest components in response to increasing drought. Moreover, πtlp was correlated with a suite of coordinated hydraulic and economics traits; therefore, it can be used to predict the position of a given species along the 'fast-slow' whole-plant economics spectrum. This study expands our understanding of the biological significance of πtlp not only in drought tolerance, but also in the plant economics spectrum.

Abstract
Aerobic composting was conducted to evaluate the effects of the different ratios (0%, 2.5%, 5%, 7.5%, and 10%) of Ca-bentonite (CB) on the speciation of Cu and Zn during pig manure composting, while pot experiment was performed to investigate the role of CB-added compost on the bio-availability of Cu and Zn to Chinese cabbage and its biomass. The results showed that the exchangeable fractions of Cu and Zn decreased, while their oxidized and residual fractions gradually increased during composting; CB addition reduced the distribution ratios of bio-available Cu and Zn in mature compost by approximately 19.84%-48.90% and 4.94%-16.39%, compared to those in the 0% CB-added treatment, and the best result was found in the 10% CB-added treatment.. Meanwhile, the pot experiment confirmed that the addition of compost considerably increased soil organic matter (OM) and electrical conductivity (EC) but decreased soil pH value. On the contrary, the application of CB effectively decreased EC and increased soil pH but inhibited OM mineralization in soil as compared to non-amended treatment. While addition of compost significantly increased plant dry biomass as compared to that with soil alone, maximum biomass was obtained[(6.51±0.34) g·pot-1] in 10% CB-added compost. After the application of CB-added compost, the contents of the bio-available factions of Cu in the harvested soil increased, while the contents of the exchangeable fractions of Zn decreased by 38.91%, 43.69%, 46.02%, 45.12%, and 54.65%, respectively. The absorption of Cu and Zn by Chinese cabbage was considerably reduced after the application of compost, while the uptake of Zn in the plant declined as the CB rates increased, and the absorption of Cu increased. The study indicated that 10% CB addition could significantly reduce the bioavailability of Cu and Zn in compost, and also showed a continuous effect on restricting the bioavailability of Zn after land utilization. Meanwhile CB amendment enhanced Chinese cabbage biomass and reduced the uptake of Zn.

Abstract
The molecular mechanisms of osteogenic differentiation of bone marrow-derived mesenchymal stem cells (BMSCs) remain to be fully elucidated. MicroRNAs (miRs) serve vital roles in the process of regulating osteogenic differentiation of BMSCs. The present study aimed to investigate the role of miR‑23a‑5p in osteogenic differentiation of human (h)BMSCs, and the underlying molecular mechanism. The results of reverse transcription‑quantitative polymerase chain reaction demonstrated that miR‑23a‑5p was significantly downregulated in the process of osteogenic differentiation. Upregulation of miR‑23a‑5p inhibited osteogenic differentiation of hBMSCs, and down‑regulated expression of miR‑23a‑5p enhanced this process, which was confirmed by alkaline phosphatase (ALP) and Alizarin Red S staining. A dual‑luciferase reporter assay confirmed that mitogen‑activated protein kinase 13 (MAPK13) was a direct target of miR‑23a‑5p. In addition, knockdown of MAPK13 inhibited osteogenic differentiation of hBMSCs, similar to the effect of upregulation of miR‑23a‑5p. Finally, the knockdown of MAPK13 also blocked the effect of miR‑23a‑5p in osteogenic differentiation of hBMSCs, which was also confirmed by ALP and Alizarin Red S staining. These results indicated that by targeting MAPK13, miR‑23a‑5p serves a vital role in osteogenic differentiation of hBMSCs, which may provide novel clinical treatments for bone injury however, further studies are required.

Abstract
Esophageal squamous cell carcinoma is the most common type of esophageal cancer in Eastern Europe and Asia, being the 6th most common cause of cancer deaths worldwide. The aim of this study was to analyze the expression of transmembrane serine protein in esophageal squamous cell carcinoma, and to correlate it with the clinical biological features of esophageal cancer. The expression of transmembrane protease serine 4 (TMPRSS4) mRNA and protein in carcinoma tissues and corresponding adjacent tissues and non-tumorous esophageal tissues was determined using PCR (qRT-PCR). The results show that both TMPRSS4 mRNA and protein expression were remarkably lower in adjacent normal tissues than in tumorous tissues. TMPRSS4 protein expression in esophageal carcinoma was correlated with patient demographic characteristics, tumor type, high TNM stages and overall survival (OS). Based on the experimental results, we conclude that TMPRSS4 is closely related to the occurrence, development and metastasis of esophageal squamous cell carcinoma.

Abstract
Sewage sludge was amended with calcium-based bentonite with addition of no more than 10% in dry weight during the 52-day aerobic composting process, the variations of temperature, pH, organic carbon, EC, total nitrogen, nitrate(NH4+-N) and ammonium(NO3--N) were investigated, as well as the compost detoxification(germination test), heavy metals(Zn, Cu, Pb, Cd) passivation and estrone(E1) elimination. The results showed that the amendment facilitated the thermophilic phase, promoted the compost heat inactivation and brought the organic carbon mineral up to more than 15.27% -19.71%. During the composting, the compost pH increased at the beginning and then gradually decreased before reaching values of 6.76-7.05, while the amendments alleviated the dramatic pH value fluctuation. The bentonite amendment reduced the salinity of the compost with final product EC remarkably lower than 1132 μS·cm-1 of the control treatment, and the effect was enhanced with the increase of addition amount. The total nitrogen content increased with time, and there was a remarkable ammonia loss in the beginning stage for the control treatment, while the bentonite addition could facilitate the total nitrogen content increase by reducing the ammonia loss. With the composting variation, the contents of NH4+-N increased and then decreased while the NO3--N content increased gradually. The bentonite addition had a slight inhibitory effect on the plant germination but did not influence the compost maturity and detoxification; meanwhile, the amendment improved the heavy metal passivation and reduced the E1 content, especially from 90.48 to 28.27 μg·kg-1 with 5% treatment during the composting. The study indicated that bentonite addition of lower than 5% was acceptable for the sludge compost amendment, which had great potential in sludge hygienization, detoxification, heavy metal passivation and E1 elimination.

Abstract
Objective: To explore the expression of serum interleukin-13 (IL-13) and significance of its gene polymorphism on the patients with acute exacerbation of bronchiectasis in acute exacerbation period. Methods: Forty-three patients with bronchiectasis in acute exacerbation period admitted into the respiratory ward of Fujian Provincial Hospital from December, 2014 to March, 2016 were included as bronchiectasis group. Thirty-three healthy controls from normal people of health examination were included as control group during the corresponding period. A total of 5 ml fasting peripheral blood sample was extracted from each individual. The IL-13 levels were determined by enzyme-linked immunosorbent assay (ELISA). IL-13 gene polymorphisms in+ 1923 C/T site and+ 2044 site were genotyped in these two groups by using polymerase chain reaction (PCR) combined with gene sequencing methods. About 7 days after admission, thirty patients with improved condition among the 43 patients were included as bronchiectasis improvement group, all had the extraction of 3 ml peripheral blood for IL-13 detection determined by ELISA. The expression of serum IL-13 and gene polymorphisms between bronchiectasis group and control group were analyzed statistically. The changes of serum IL-13 between bronchiectasis group and bronchiectasis improvement group were also analyzed statistically. Results: The serum IL-13 level was lower in the bronchiectasis group in acute exacerbation period than that of the healthy controls [(31.1±26.3) vs (70.6±53.6) μg/L, P<0.05]. There was no significant difference of the genotype distribution in + 1923C/T site of IL-13 gene between the two groups (χ(2)=0.915, P>0.05). In the bronchiectasis group, the C and T allele frequencies at+ 1923 site of IL-13 gene were 79.1% and 20.9%, respectively, and its single nucleotide polymorphism (SNP) was in strong linkage disequilibrium with the SNP IL-13+ 2044G/A site (R(2)=0.835, P<0.001). There was no significant difference of the serum IL-13 between allele T_ groups and allele CC group, and also no significant difference between allele A_ groups and allele GG group (P>0.05). Conclusion: The IL-13 levels decreased specifically in the bronchiectasis group in acute exacerbation period, but IL-13+ 1923C/T and+ 2044G/A polymorphisms are not significantly related to the susceptibility of bronchiectasis.

Abstract
Aiming to expand the utilization of porous silicate minerals in the remediation of heavy metal contaminated soil,the mesoporous material SBA-15 was successfully synthesized by using sodium silicate as silica source in this study.And the obtained SBA-15 samples were characterized by TEM,X-ray diffraction,N2 adsorption-desorption and FTIR.Furthermore,characterization of Cd (Ⅱ) adsorption and sealing performance onto SBA-15 were evaluated through batch experiment,and the remediation potential of Cd (Ⅱ) contaminated soil was investigated by brassica planting in a pot experiment.The results showed that SBA-15 had the mesoporous structure with surface area of 507.3 m2·g-1 and pore size of 7.38 nm.The maximum Cd (Ⅱ) adsorption capacity was 76.43 mg·g-1 at pH above 7.0 with the adsorption isotherm fitting the Langmuir model in the solution of 100 mg·L-1 Cd (Ⅱ).The increase in ionic strength reduced the Cd (Ⅱ) adsorption capacity.The Cd (Ⅱ) loaded SBA-15 could be regenerated with 0.1 mol·L-1 HNO3,while Cd (Ⅱ) could be strongly sealed in the pore structure after introduction of sodium silicate into the system.The pot experiment proved that the addition of SBA-15(4.5 g·kg-1) into Cd-contaminated soil could reduce Cd (Ⅱ) availability,enhance the transformation of soluble and exchangeable Cd (Ⅱ) fractions into carbonate and Fe-Mn oxides bounded forms,inhibit the Cd (Ⅱ) accumulation in the plant tissue and improve the brassica growth.Based on these results,it can be concluded that combination of the SBA-15 particle with sodium silicate has great potential to remediate Cd (Ⅱ) contaminated soil through adsorption and sealing properties.

Abstract
Aiming to evaluate the influence of alkali solids amendment on the sewage sludge aerobic composting and to declare the potential of related composts on infertile soil amelioration, sewage sludge and sawdust mixture were amended with straw biochar, hardwood biochar, fly ash and lime by 10% addition ratio in dry weight during the aerobic composting process; finally, potential of the related composts on the infertile soil amelioration was investigated by pot experiment. The results showed that the alkali solids amendment could prolong the thermophilic phase, and promote the composting material heat inactivation. Addition of straw and hardwood biochar facilitated more than 21.65% and 18.16% organic matter degradation. During the composting, the compost pH decreased at the beginning and then gradually increased before reached values of 6.78-7.33, while the fly ash and lime amendments could lead to higher pH values in the beginning stage. The alkali solids amendment reduced the salinity of the compost with final products EC lower than 3000 μS·cm-1. The addition of straw and hardwood biochar could increase the total nitrogen content by reducing the ammonia loss at the beginning, while the fly ash and lime amendments would result in ammonia loss in the beginning stage. Despite the composting variation, the contents of nitrate increased and the ammonium salt content decreased gradually. The biochar addition can accelerate the nitrate transformation while the fly ash and lime amendment had slight inhibitory effect on the nitrate transformation and plant germination. The pot experiment revealed that applying compost products could significantly improve the brassica growth, Cu and Zn micronutrients accumulation since the compost addition could increase the soil organic carbon content, as well as soil N, P, and K contents. Compared with the non-amended compost, the alkali solids amendment could slightly reduce the Cu and Zn micronutrients accumulation, while the fertile potentials were acceptable. The study indicated that straw and hardwood biochar were more suitable than fly ash and lime as compost amendment, and the related compost products had great potential on infertile soil amelioration.

Abstract
Silicate nanoparticles(nSiO2) are a kind of widely used engineering material. In order to improve the Cd2+ adsorption ability, the EDTA-modified nSiO2 nanoparticles were prepared by grafting method and characterized by TEM, N2 adsorption-desorption, FTIR, and TGA. The effects of solution pH, contact time, temperature and ionic strength were examined. The adsorption mechanism was further investigated by XPS. The results showed that the EDTA-nSiO2 nanoparticles possessed excellent stability, and were successfully prepared. Cd2+ adsorption was mainly controlled by solution pH. The raw nSiO2 had limited Cd2+ adsorption ability, while the EDTA-modified nSiO2 particles had significantly improved adsorption performance. At high pH, the Cd2+ adsorption rate increased and kept balance above pH 4.0. The Cd2+ adsorption was an endothermic spontaneous process which could be finished within 1 h. Langmuir model could be used to describe the adsorption isotherm. The temperature ranged from 293-313 K during the process, while the maximum adsorption was observed at higher temperature. Higher ionic strength could inhibit the Cd2+ adsorption. The Cd2+ adsorption decreased from 0.433 to 0.294 mmol·g-1, when NaCl concentration varied from 0 to 100 mmol·L-1. The desorption of Cd2+ from the EDTA-nSiO2 nanoparticles was carried out with distilled water, 0.1 mol·L-1 NaCl and 0.1 mol·L-1 HCl. The maximum Cd2+ desorption of 94.36% was obtained at 0.1 mol·L-1 HCl. Based on the results of thermodynamics, pH, ionic strength, and XPS analysis, it could be concluded that Cd2+ adsorption was a multiple process dominated by chemical chelating reaction, physical adsorption and ion exchange. This study indicated that the EDTA-nSiO2 is an effective engineering nanomaterial that could be used in Cd2+ adsorption.

Abstract
BACKGROUND AND AIMS Ferns are abundant in sub-tropical forests in southern China, with some species being restricted to shaded understorey of natural forests, while others are widespread in disturbed, open habitats. To explain this distribution pattern, we hypothesize that ferns that occur in disturbed forests (FDF) have a different leaf cost-benefit strategy compared with ferns that occur in natural forests (FNF), with a quicker return on carbon investment in disturbed habitats compared with old-growth forests. METHODS We chose 16 fern species from contrasting light habitats (eight FDF and eight FNF) and studied leaf functional traits, including leaf life span (LLS), specific leaf area (SLA), leaf nitrogen and phosphorus concentrations (N and P), maximum net photosynthetic rates (A), leaf construction cost (CC) and payback time (PBT), to conduct a leaf cost-benefit analysis for the two fern groups. KEY RESULTS The two groups, FDF and FNF, did not differ significantly in SLA, leaf N and P, and CC, but FDF had significantly higher A, greater photosynthetic nitrogen- and phosphorus-use efficiencies (PNUE and PPUE), and shorter PBT and LLS compared with FNF. Further, across the 16 fern species, LLS was significantly correlated with A, PNUE, PPUE and PBT, but not with SLA and CC. CONCLUSIONS Our results demonstrate that leaf cost-benefit analysis contributes to understanding the distribution pattern of ferns in contrasting light habitats of sub-tropical forests: FDF employing a quick-return strategy can pre-empt resources and rapidly grow in the high-resource environment of open habitats; while a slow-return strategy in FNF allows their persistence in the shaded understorey of old-growth forests.

Abstract
Melanoma is one of the most malignant forms of skin cancer; with a rapidly increasing prevalence. Early-stage melanoma is curable, but advanced metastatic melanoma is almost always fatal, and patients with such advanced disease have short median survival. Surgery and radiotherapy play a limited role in the treatment of metastatic melanoma. Rather, chemotherapy remains the mainstay of treatment, although other approaches, including biotherapy and gene therapy, have been attempted. The authors hereby, evaluated the use of temozolomide (TMZ) for treating metastatic melanoma compared to dacarbazine (DTIC), the effectiveness of TMZ for treating brain metastases, as well as TMZ resistance and how the efficacy of TMZ in malignant melanoma can be increased. Two chemotherapeutic regimens are commonly used for palliative treatment of malignant melanoma: intravenous administration of DTIC and oral administration of the alkylating agent temozolomide (TMZ). Compared to DTIC, TMZ is very well tolerated and has an advantage in terms of improving the quality of life of patients with metastatic melanoma. While the prognosis is currently unpromising, chemotherapy plays a palliative role for patients with metastatic melanoma. The toxicity of treatment regimens based on DTIC and TMZ do not differ significantly, although TMZ is costlier. These findings provide a reference for future researchers via a comprehensive analysis of the relevant literature.

Abstract
D-galactose injection has been shown to induce many changes in mice that represent accelerated aging. This mouse model has been widely used for pharmacological studies of anti-aging agents. The underlying mechanism of D-galactose induced aging remains unclear, however, it appears to relate to glucose and 1ipid metabolic disorders. Currently, there has yet to be a study that focuses on investigating gene expression changes in D-galactose aging mice. In this study, integrated analysis of gas chromatography/mass spectrometry-based metabonomics and gene expression profiles was used to investigate the changes in transcriptional and metabolic profiles in mimetic aging mice injected with D-galactose. Our findings demonstrated that 48 mRNAs were differentially expressed between control and D-galactose mice, and 51 potential biomarkers were identified at the metabolic level. The effects of D-galactose on aging could be attributed to glucose and 1ipid metabolic disorders, oxidative damage, accumulation of advanced glycation end products (AGEs), reduction in abnormal substance elimination, cell apoptosis, and insulin resistance.

Abstract
BACKGROUND Malignant melanoma is the most aggressive and deadly form of skin cancer. Dacarbazine (DTIC) has been the approved first-line treatment for metastatic melanoma in routine clinical practice. However, response rates with single-agent DTIC are low. The objective of this study was to compare the efficacy and safety of DTIC with or without placebo and DTIC-based combination therapies in patients with advanced metastatic melanoma. METHODS We searched from electronic databases such as The Cochrane Library, MEDLINE, EBSCO, EMBASE, Ovid, CNKI, and CBMDisc from 2003 to 2013. The primary outcome measures were overall response and 1-year survival, and the secondary outcome measurements were adverse events. RESULTS Nine randomized controlled trials (RCTs) involving 2,481 patients were included in the meta-analysis. DTIC-based combination therapies was superior to DTIC alone in overall response (combined risk ratio [RR] = 1.60, 95% confidence interval [CI]: 1.27-2.01) and 1-year survival (combined RR = 1.26, 95% CI: 1.14-1.39). Patients with DTIC-based combination therapies had higher incidence of adverse events including nausea (combined RR = 1.23, 95% CI: 1.10-1.36), vomiting (combined RR = 1.73, 95% CI: 1.41-2.12) and neutropenia (combined RR = 1.75, 95% CI: 1.42-2.16) compared to the group for DTIC alone. CONCLUSION These data suggested that DTIC-based combination therapies could moderately improve the overall response and the 1-year survival but increased the incidence of adverse events. Further large-scale, high-quality, placebo-controlled, double-blind trials are needed to confirm this conclusion.

Abstract
Dianthus amurensis, commonly known as Amur Pink, is a species of the genus Dianthus in the family Caryophyllaceae. This perennial Dianthus is also a Chinese medicinal herb. In August 2012, mosaic, leaf cupping, leaf distortion, reduction in leaf size, and flower-breaking symptoms were observed on some D. amurensis plants in a Chinese herb nursery in Changchun, Jilin Province, China. Disease incidences ranged from 40 to 50% in different plots. Symptoms on diseased D. amurensis were similar to those on the diseased D. caryophyllus, D. barbatus, and D. japonicus. The symptoms resembled to those caused by Carnation vein mottle virus (CVMoV), a member of genus Potyvirus in the family Potyviridae (3). CVMoV infects carnations (D. caryophyllus) worldwide and causes a serious disease. To investigate the presence of CVMoV, leaf samples were collected from three symptomatic plants and tested by dot-ELISA using universal potyvirus group monoclonal antibody (Agdia, Inc., Elkhart, IN). The antibody reacted with the diseased samples, supporting the presence of a potyvirus. To identify the potyvirus species, total nucleic acids were extracted from the diseased samples by a CTAB method (2) and used as template in RT-PCR with potyvirus universal primers Sprimer and M4T (1). An amplicon of the expected size (~1.7 kb) was obtained from all three diseased samples. The amplicons were cloned into pMD18-T vector (TaKaRa, Dalian, China) and sequenced. Sequences obtained from all three samples were identical and deposited in GenBank (Accession No. KJ605654). BLAST search showed that the nucleotide sequence shared 97 and 98% identity with a Japanese CVMoV isolate infecting D. japonicus (AB017630) (3) and a Korean CVMoV isolate (AY512554), respectively. The results confirmed the association of CVMoV with the disease on D. amurensis. To determine the pathogenicity of CVMoV to D. amurensis plants, purified CVMoV from the diseased plants were used to inoculate to healthy Dianthus spp. plants. Inoculated Dianthus spp. plants also showed the symptoms of mottle, leaf cupping, and leaf distortion, and CVMoV could be detected by RT-PCR from these plants. The result confirms that CVMoV is the causal agent of the disease. To our knowledge, this is the first report of CVMoV infection in D. amurensis. Since D. amurensis is economically important in China, proper virus management strategies for the cultivation of this crop should be adopted. References: (1) J. Chen et al. Arch.

Abstract
Tomato mottle mosaic virus (ToMMV), a tentative member in genus Tobamovirus, was first reported from a greenhouse tomato sample collected in Mexico in 2013 (2). In August 2013, foliar mottle, shrinking, and necrosis were observed on pepper plants in several vegetable greenhouses of Lhasa, Tibet Autonomous Region, China. Seven symptomatic samples were collected and tested by dot-blot ELISA with antisera against Cucumber mosaic virus, Tobacco mosaic virus (TMV), Cucumber green mottle mosaic virus, Tomato spotted wilt virus, Turnip mosaic virus, and Broad bean wilt virus 2 (kindly provided by Dr. Xueping Zhou of Zhejiang University, China) (3). One of the bell pepper (Capsicum annuum var. grossum) samples reacted with the TMV antibody. Rod-shaped virus particles 300 nm in length were observed in this sample under electron microscopy. The results suggested that a tobamovirus closely related to TMV might be a causal agent. Total nucleic acids were then extracted from all seven samples using a CTAB method (1) and tested by RT-PCR using a pair of tobamovirus degenerate primers, TobamoF (GCWAAGGTKGTWYTBGTRGAYGG) and TobamoR (GTAATTGCTATTGDGTWCCWGC). These two primers were designed according to a conserved region of the TMV, Tomato mosaic virus, and ToMMV genomes (nt 2551-3433 of ToMMV genome [KF477193]). An amplicon of approximately 880 bp was obtained only from the TMV-positive sample. The amplicon was cloned and sequenced (GenBank Accession No. KJ605653). NCBI BLAST search showed that it shared the highest identity (99%) with ToMMV (KF477193), and shared the sequence homology of 82% to Tomato mosaic virus (AF332868) and 77% to TMV (V01408). The results indicated that the symptomatic pepper was infected with ToMMV. To investigate the distribution and incidence of ToMMV, 313 samples of symptomatic pepper, tomato, pumpkin, cucumber, radish, Chinese cabbage, broad bean, pea, and kidney bean samples were collected from 65 fields in Yunnan Province and Tibet Autonomous Region, and tested in RT-PCR with ToMMV-specific primers ToMMVF (AGAGAGATGGCGATAGGTTAAC, identical to nt 830-851 of ToMMV genome, GenBank Accession No. KF477193) and ToMMVR (CTGCAGTCATAGGATCTACTTC, complementary to nt1849-1828). The virus was detected in three tabasco peppers (C. frutescens) from Yunnan and one bell pepper plant from Tibet, suggesting that ToMMV has a restricted host range and is not common in these two regions. To our knowledge, this is the first report of natural infection of ToMMV in peppers as well as in China. References: (1) R. Li et al. J. Virol. Methods 154:48, 2008. (2) R. Li et al.

Abstract
Panax notoginseng, an important medicinal herb commonly known as notoginseng, san qi, or tian qi, is in the family Araliaceae. The herb is mainly cultivated in Guangxi and Yunnan provinces of southern China for its root, which is used in Chinese herbal medicine to treat various blood disorders. In December 2012, Panax yellowing was observed in several notoginseng farms with prevalence of 5 to 10% in Wenshan, Yunnan Province. Foliar symptoms included yellowing, shrinking, curling, and blistering. Leaf samples collected from 15 symptomatic plants were initially tested by negative staining electron microscopy, and no distinct virions were observed. Total nucleic acids were extracted from these samples by a CTAB method and used as templates in RT-PCR for presence of criniviruses, tobamoviruses, and tospoviruses, but results were negative. Infestation of whiteflies (Bemisia tabaci) has been a problem on these farms in recent years, suggesting a whitefly-transmitted begomovirus as potential causal agent. To explore this possibility, the samples were tested by PCR using degenerate primers BegoAFor1 and BegoARev1 described by Ha et al. (3). Amplicons of ~1.2 kbp were obtained from 12 out of 15 samples, indicating the presence of a putative begomovirus. These amplicons were cloned and sequenced in both directions. BLAST search showed that they had high sequence identities (94 to 95%) to the genome of Tomato yellow leaf curl China virus (TYLCCNV). A pair of virus-specific primers, TYLCCNVFa (5'-TGRTAGGWACYTGAGTAGAGTGG-3') and TYLCCNVRa (5'-TCRTCCATCCATATCTTCCCAA-3'), was then designed and used to amplify the remaining genomic sequence. The full-length genomic sequence of one isolate, YWSh03, was determined to be 2,733 nt (KJ477327). Sequence comparison showed that the genome of YWSh03 shared 96.2% nucleotide sequence identity with that of TYLCCNV-[G102] (AM050555). PCR using primers Beta01 and Beta02 (1) was also tested for the association of betasatellite with this virus. A DNA fragment was obtained from isolate YWSh03, and its sequence was determined to be 1,336 bp (KJ477326). This sequence has 99.9% nucleotide sequence identity to Tomato yellow leaf curl China betasatellite (TYLCCNB) [Y10] (AJ421621). The results show that TYLCCNV, a virus infecting tomato, tobacco, kidney bean, and several weeds (2), is also associated with the yellowing disease in P. notoginseng. To determine whether TYLCCNV and TYLCCNB might cause disease on P. notoginseng, infectious clones of TYLCCNV and TYLCCNB provided by Dr. Xueping Zhou (Zhejiang University, China) were used to inoculate to 44 healthy P. notoginseng plants by an Agrobacterium-mediated method. Thirty-four inoculated plants showed typical symptoms of yellowing, curling, and stunting, confirming TYLCCNV and TYLCCNB are the causal agents of the disease. To further investigate the distribution and incidence of the virus, 258 symptomatic P. notoginseng samples were collected from 18 fields in Wenshan, Honghe, Qujing, and Kunming of Yunnan Province and tested by PCR with TYLCCNV-specific primers of TYLCCNVdF (5'-CCTGTATATGCGACTTTGAAAGT-3') and TYLCCNVdR (5'-CCCAATTCCAGCTATAAAGAGTA-3'). The virus was detected in 149 samples (57.8%), indicating that TYLCCNV infection of P. notoginseng is common. However, the agent causing the disease in the 109 symptomatic plants lacking TYLCCNV remains under investigation. To our knowledge, this is the first report of TYLCCNV with TYLCCNB infecting P. notoginseng and the family Araliaceae. References: (1) R. W. Briddon et al. Mol Biotechnol. 20:315, 2002. (2) J. H.

Abstract
The common Chinese cuttlefish (Sepiella maindroni) is one of the popular edible cephalopod consumed across Asia. To facilitate the population genetic investigation of this species, we developed fourteen polymorphic microsatellite makers from expressed sequence tags of S. maindroni. The number of alleles at each locus ranged from 6 to 10 with an average of 7.9 alleles per locus. The ranges of observed and expected heterozygosity were from 0.615 to 0.962 and 0.685 to 0.888, respectively. Four loci were found deviated significantly from Hardy-Weinberg equilibrium. The polymorphism information content ranged from 0.638 to 0.833. These polymorphic microsatellite loci will be helpful for the population genetic, genetic linkage map, and other genetic studies of S. maindroni.

Abstract
This study aimed to concurrently investigate the expressions of receptor for advanced glycation end products (RAGE), reversion inducing cysteine-rich protein with Kazal motifs (RECK) and matrix metalloproteinase 9 (MMP9) in nasopharyngeal carcinoma (NPC) and their correlations with clinicopathological properties. Using immunohistochemistry, we found that RECK expression was downregulated in NPC tissues compared with chronic nasopharyngitis (CNT) tissues, while RAGE and MMP9 expressions were upregulated. We further found that RECK expression level was inversely correlated with MMP9 expression level in NPC, whereas RAGE expression level was positively correlated with MMP9 expression level. Moreover, aberrant expressions of these proteins had a positive correlation with the titers of EBVCA-IgA, lymphatic metastasis, recurrence and survival. Together, these findings suggest that dysregulations of RECK and RAGE expressions may be collectively involved in tumor progression of NPC by regulating MMP9 expression and that they may be a good prognostic predictors for NPC.

Abstract
Highly ordered channel structure SBA-15 was widely concerned as new adsorbents in environmental protection, in order to increase its heavy metal ions adsorption ability from aqueous solution, the diamine -modified porous silicate SBA-15 was synthesized by a hydrothermal grafting method and characterized by TEM, X-ray diffraction, FTIR and N2 adsorption-desorption. The SBA-15 and modified SBA-15 samples were used as sorbents to adsorb Cd(II) ions from aqueous solution. The effect of experimental parameters, such as pH, contact time, sorbent dosage and temperature were examined, and the maximum adsorption amount was also calculated. The results showed that under same conditions, the Cd(II) removal rate was higher for 2N-SBA-15 than that of the unmodified SBA-15. The adsorption process was controlled by system pH. The highest removal rate could reached about 95% after pH was higher than 4. Adsorption equilibrium was reached within 30 minutes,and more than 95% Cd2+ was adsorbed when 7.5-20 mg sorbent was added into 100 mL solution contained 25 mg x L(-1) Cd2+. The adsorption capacity increased from 94.73% to 98.22% with temperature increased from 25 degrees C to 35 degrees C. The Langmuir model can be used to describe adsorption isotherms. The adsorption capacity of Cd2+ was 0.9 mmol x g(-1) which is comparable to the adsorption capacity of various adsorbents reported in the literature, and 0.1 mol x L(-1) HCl could remove nearly 93% Cd2+ from 2N-SBA-15 particles. Based on the thermodynamic, pH, XPS and Zeta potential analysis results in this study, it could be concluded that the adsorption process was an endothermic and spontaneous reaction which contained physical adsorption, ion exchange and chelating reaction etc. The study indicated that the diamine -modified ordered mesoporous material SBA-15 is a potential sorbent which could be used for the aqueous Cd2+ removal.

Abstract
It is important to understand the ecophysiological characters of plants when exploring mechanisms underlying species substitution in the process of plant succession. In the present study, we selected 34 woody species from different stages of secondary succession in subtropical forests of southern China, and measured their hydraulic conductivity, gas exchange rates, leaf nutrients and drought-tolerance traits such as xylem resistance to cavitation, turgor loss point and carbon isotope ratio. Principal component analysis revealed that early-, mid- and late-successional species were significantly separated along axis 1, which was strongly associated with hydraulic-photosynthetic coordination. In contrast to species distributed in late-successional forest, early-successional species had the highest hydraulic conductivity, net photosynthetic rates, photosynthetic nitrogen and phosphorus use efficiencies, but had the lowest photosynthetic water-use efficiency. However, changes of the measured drought-tolerance traits of the 34 species along the succession did not demonstrate a clear trend - no significant correlations between these traits and plant successional stages were found. Moreover, the trade-off between hydraulic efficiency and safety was not identified. Taken together, our results suggested that hydraulic efficiency and photosynthetic function, rather than drought tolerance, play an important role in species distributions along plant succession in subtropical forests.

Abstract
A trust network is a social network in which edges represent the trust relationship between two nodes in the network. In a trust network, a fundamental question is how to assess and compute the bias and prestige of the nodes, where the bias of a node measures the trustworthiness of a node and the prestige of a node measures the importance of the node. The larger bias of a node implies the lower trustworthiness of the node, and the larger prestige of a node implies the higher importance of the node. In this paper, we define a vector-valued contractive function to characterize the bias vector which results in a rich family of bias measurements, and we propose a framework of algorithms for computing the bias and prestige of nodes in trust networks. Based on our framework, we develop four algorithms that can calculate the bias and prestige of nodes effectively and robustly. The time and space complexities of all our algorithms are linear with respect to the size of the graph, thus our algorithms are scalable to handle large datasets. We evaluate our algorithms using five real datasets. The experimental results demonstrate the effectiveness, robustness, and scalability of our algorithms.

Abstract
We describe herein a 68-year-old woman who was diagnosed with a quite rare entity of intraductal papillary mucinous neoplasms (IPMNs) occurring simultaneously in the left lateral lobe of liver and the tail of pancreas. Abdominal computed tomography and magnetic resonance cholangiopancreatography showed a cystic dilatation of the pancreatic duct in the pancreatic tail, which suggested an IPMN, and multiple intrahepatic duct stones in the left lateral lobe. The patient underwent a laparoscopic left lateral hepatolobectomy and spleen-preserving distal pancreatectomy. Intra-operative finding of massive mucin in the dilated bile duct implied an intraductal mucinous tumor in the liver. The diagnosis of synchronous IPMNs in the liver and pancreas was confirmed by pathological examination. The patient was followed up for 6 mo without signs of recurrence. Although several cases of IPMN of liver without any pancreatic association have been reported, the simultaneous occurrence of IPMNs in the liver and pancreas is very rare. To the best of our knowledge, it is the first reported case treated by laparoscopic resection.

Abstract
BACKGROUND The Wenchuan earthquake was a catastrophic earthquake in China. The aim of this study is to explore longitudinally the rates of post-traumatic stress disorder (PTSD) and depression in adolescents after the Wenchuan earthquake, and to identify independent predictors of PTSD. METHOD PTSD and depression symptoms among adolescents at 6, 12 and 18 months after the Wenchuan earthquake were investigated using the PTSD Checklist Civilian Version and the Beck Depression Inventory (BDI). Subjects in this study included 548 high school student survivors in a local boarding high school. RESULTS The rates of PTSD symptoms were 9.7%, 1.3% and 1.6% at the 6-, 12- and 18-month follow-ups, respectively. BDI scores were found to be the best predictor of severity of PTSD at 6, 12 and 18 months. Gender was another variable contributing significantly to PTSD at 6 and 12 months after the earthquake. In the 12-month follow-up, home damage was found to be a predictor of severity of PTSD symptoms. Being a child with siblings was found to be a predictor of severity of PTSD symptoms at 12 and 18 months after the earthquake. CONCLUSIONS PTSD symptoms changed gradually at various stages after the earthquake. Depression symptoms were predictive of PTSD symptoms in the 18-month follow-up study. Other predictors of PTSD symptoms included female gender and being a child with siblings. The results of this study may be helpful for further mental health interventions for adolescents after earthquakes.

Abstract
Singularity problems of scatter matrices in Linear Discriminant Analysis (LDA) are challenging and have obtained attention during the last decade. Linear Discriminant Analysis via QR decomposition (LDA/QR) and Direct Linear Discriminant analysis (DLDA) are two popular algorithms to solve the singularity problem. This paper establishes the equivalent relationship between LDA/QR and DLDA. They can be regarded as special cases of pseudo-inverse LDA. Similar to LDA/QR algorithm, DLDA can also be considered as a two-stage LDA method. Interestingly, the first stage of DLDA can act as a dimension reduction algorithm. The experiment compares LDA/QR and DLDA algorithms in terms of classification accuracy, computational complexity on several benchmark datasets and compares their first stages. The results confirm the established equivalent relationship and verify their capabilities in dimension reduction.
