Abstract
Long non-coding RNAs (lncRNAs) play important roles in plant development and stress responses. MicroRNAs (miRNAs) are involved in transcriptional and post-transcriptional gene regulation. It is not clear how lncRNA-mediated plant responses to cold stress and how lncRNAs, miRNAs and target mRNAs cooperate subject to the competing endogenous RNA (ceRNA). We interpreted the function of lncRNAs in the winter wheat cultivar Dongnongdongmai 1 (Dn1). A total of 9970 putative lncRNAs were initially identified from three Dn1 lncRNA libraries (5 °C, -10 °C and -25 °C) using high-throughput sequencing. Among the 14,626 genes detected via weighted gene co-expression network analysis, 7435 lncRNAs were co-expressed with 7191 mRNAs. We found six modules related to cold resistance in the lncRNA-mRNA weighted co-expression network, and the functions of mRNAs were similar in each module. Antioxidant systems and hormones played important roles in low-temperature responses. RNA sequencing analysis revealed that interactions between the 384 lncRNAs and 70 miRNAs were required for ceRNA activity. According to ceRNA activity, 225 lncRNAs, 60 miRNAs and 621 target mRNAs were involved in the regulatory networks of the cold stress response. Notably, a conserved region was found in the complementary regions of lncRNAs and miR164/408 but had reverse expression trends in the ceRNA network. Our results reveal possible roles of lncRNAs-mRNAs in the regulatory networks associated with tolerance to low temperature and provide useful information for more strategic use of genomic resources in wheat breeding.

Abstract
This study focused on the distribution, combined pollution, potential source and risk assessment of 17 antibiotics in an aquaculture ecosystem surrounding the Yellow sea, North China. Antibiotics were detected in various matrices (seawater, sediment/biofilm, organism and feed) in different aquaculture modes (greenhouse and outdoor aquaculture) during the wet and dry seasons in coastal areas of Shandong province. The innovation points of the study were as follows: (1) To the best of our knowledge, this study was one of the few to investigate the occurrence and distribution of antibiotics in mariculture environments along the Yellow Sea coast; (2) Biofilms, a focus of the study, might act as a sink for antibiotics in the aquaculture ecosystem; and (3) The correlation of heavy metals and antibiotic concentrations was proved, which could correspondingly be used as an indicator for antibiotic concentrations in the studied area. The levels of antibiotics in water were observed to be relatively low, at the ng/L level. Trimethoprim was the most prevalent antibiotic, and was detected in all water samples. Oxytetracycline was detected at high concentrations in biofilms (up to 1478.29 ng/g). Moreover, biofilms exhibited a higher antibiotic accumulation capacity compared to sediments. Concentrations of oxytetracycline and doxycycline were high in feed, while other antibiotics were almost undetected. Tetracycline was widely detected and the concentration of enrofloxacin was highest in organisms. Correlation analysis demonstrated that environmental parameters and other coexisting contaminants (e.g. heavy metals) significantly affected antibiotic concentrations. In addition, the concentration of Zn was significantly correlated with the total antibiotic concentration and was proportional to several antibiotics in water and sediment (biofilm) samples (p < 0.01). High Mn concentrations were closely related to total and individual (e.g. sulfadiazine, sulfamethazine and enrofloxacin) antibiotic levels, which may result in the combined contamination of the environment. Antibiotics in estuaries and groundwater generally originated from aquaculture wastewater and untreated/treated domestic sewage. Most of the detected antibiotics posed no risk to the environment. Ciprofloxacin and enrofloxacin found in water may present high ecological and resistance risks, while the two antibiotics observed to accumulate in fish may pose a considerable risk to human health through diet consumption. All antibiotics detected in seafood were lower than the respective maximum residue limits. This study can act as a reference for the government for the determination of antibiotic discharge standards in aquaculture wastewater and the establishment of a standardized antibiotic monitoring and management system.

Abstract
Objective Exposure to radon causes lung cancer. The scope and impact of exposure among Canadian workers have not been assessed. Our study estimated occupational radon exposure in Canada and its associated lung cancer burden. Methods Exposed workers were identified among the working population during the risk exposure period (1961–2001) using data from the Canadian Census and Labour Force Survey. Exposure levels were assigned based on 12,865 workplace radon measurements for indoor workers and assumed to be 1800 mg/m3 for underground workers. Lung cancer risks were calculated using the Biological Effects of Ionizing Radiation (BEIR) VI exposure-age-concentration model. Population attributable fractions were calculated with Levin’s equation and applied to 2011 Canadian lung cancer statistics. Results Approximately 15.5 million Canadian workers were exposed to radon during the risk exposure period. 79% of exposed workers were exposed to radon levels < 50 Bq/m3 and 4.8% were exposed to levels > 150 Bq/m3. We estimated that 0.8% of lung cancers in Canada were attributable to occupational radon exposure, corresponding to approximately 188 incident lung cancers in 2011. Conclusions The lung cancer burden associated with occupational radon exposure in Canada is small, with the greatest burden occurring among those exposed to low levels of radon.

Abstract
Urban heat island (UHI) effect has serious negative impacts on urban ecosystems and human well-being. Mitigation of UHI using nature-based solutions is highly desirable. It was well known that urban green infrastructure (UGI), i.e., urban vegetation, can effectively mitigate UHI effect. However, the potential of urban blue infrastructure (UBI), i.e., urban surface water, on UHI mitigation is not well understood, although its potential to lower UHI effect via evaporation is similar to the biophysical mechanism of evapotranspiration through vegetation. In this paper, we study the relationship between UBI and land surface temperature (LST) in Wuhan city in central China, using a normalized difference water index (NDWI), maximum local cool island intensity and the maximum cooling distance as indicators for the cooling effects of UBI, respectively. We found a significant negative linear relationship between mean LST and NDWI after NDWI passes a critical threshold value. NDWI is an effective biophysical parameter to delineate the spatial distribution of UBI. The cooling effects of UBI are influenced both by its size and shape. Water surface temperature decreased logarithmically with increasing UBI size, critical threshold values of UBI size corresponding to maximum cooling efficiency do exists. Maximum cooling distance and maximum local cool island intensity are also affected by the shape and size of UBI, and exhibit seasonal and spatial variations. These results provide insights for urban landscape planning regarding how to use UBI as a nature-based solution to improve urban thermal environment.

Abstract
We have explored the relations between clinicopathological features and cervical lymph node metastases (LNM) in patients with cN0 squamous cell carcinoma (SCC) of the tongue, and developed and validated a nomogram for predicting the risk of their development. Clinical data on 230 patients with cN0 SCC of the tongue who had had primary extended excision and lymph node dissection of the neck were collected retrospectively. They were divided into a development cohort and a validation cohort in a 4:1 ratio. Logistic regression analysis was used to assess the risk factors of cervical LNM in patients in the development cohort, and a nomogram was established to predict the risk of such nodes. In the validation cohort, the predictive performance and compliance of the model were evaluated using the consistency index (C-index) and calibration curve, and the clinical value was evaluated by decision curve analysis. Of the 230 patients, 60 had cervical LNM, of which 60 were invaded (26%). Analysis of the development cohort showed that the site of the primary lesion, depth of invasion, size of the tumour, and histopathological grade were included in the prediction model, which was validated in the validation cohort. Consistency was high (C-index=0.846), calibration good, and it was clinically valuable. The nomogram could be used to predict the probability of occult cervical LNM before operation in patients with stage cN0 SCC of the tongue. It could also be used as a reference tool for dissection of cervical nodes and a communication tool between the doctor and the patient.

Abstract
Objective: To detect the effect and regulatory mechanism of human ether à go-go related gene 1 (Herg 1) knockdown on the proliferation and invasion of osteosarcoma (OS). Methods: We constructed a recombinant adenovirus vector (Ad5-Herg1-shRNA) expressing short hair RNA (shRNA) against Herg1 and tested the knockdown efficiency. Then, the effects of Herg 1 knockdown on the proliferation, growth and invasion of osteosarcoma were measured by using cell counting kit-8 (CCK-8), wound healing assay, Transwell assay and xenograft model of nude mice, respectively. Tandem affinity purification, mass spectrometry and dual luciferase reporter assay were used to find out the molecules interacted with Herg1. Western blot was used to detect the expressions of large tumor suppressor gene (LATS1), p-LATS1, Yes-associated protein (YAP) and p-YAP in cells after infection of Ad5-Herg1-shRNA. Results: Compared to Ad5-control-shRNA, Ad5-Herg1-shRNA dramatically inhibited the expression of Herg1 in OS cells. The result of CCK8 array demonstrated that 143B cell vitalities of Ad5-Herg1-shRNA1 and Ad5-Herg1-shRNA2 group were (65.47±3.90)% and (79.90±1.52)%, significantly lower than (100.00±6.14)% of Ad5-control-shRNA group. Meanwhile, U2OS cell vitality of Ad5-Herg1-shRNA1 and Ad5-Herg1-shRNA2 group were (69.69±1.36)% and (76.72±2.75)%, significantly lower than (100.00±3.01)% of Ad5-control-shRNA group (all P<0.001). The results of wound healing array showed that 143B cell migration rates of Ad5-Herg1-shRNA1 and Ad5-Herg1-shRNA2 group were (33.03±2.88)% and (36.47±4.16)%, significantly lower than (97.78±2.28)% of Ad5-control-shRNA group. Meanwhile, U2OS cell migration rates of Ad5-Herg1-shRNA1 and Ad5-Herg1-shRNA2 group were (68.07±0.90)% and (73.97±1.25)%, significantly lower than (96.50±1.12)% of Ad5-control-shRNA group (all P<0.001). The results of Transwell showed that 143B cell invasion numbers of Ad5-Herg1-shRNA1 and Ad5-Herg1-shRNA2 group were 36.50±12.15 and 44.83±7.62, significantly lower than 195.33±19.68 of Ad5-control-shRNA group. Meanwhile, U2OS cell migration rates of Ad5-Herg1-shRNA1 and Ad5-Herg1-shRNA2 group were 21.83±7.99 and 22.85±7.08, significantly lower than 83.33±12.36 of Ad5-control-shRNA group (all P<0.001). The results of xenograft model of OS showed that the tumor volume and weight of Ad5-Herg1-shRNA group were significantly smaller than of Ad5-control-shRNA group after 14 days and 5 weeks of inoculation, respectively (P<0.001). Moreover, knockdown of Herg1 inhibited the metastasis of OS cells. In mechanism, Herg1 protein interacted with NF2 protein. Knockdown of Herg1 significantly suppressed the expression levels of LATS1 and YAP protein, and promoted the phosphorylation of LATS1 and YAP in OS cells (all P<0.001). Conclusion: Our findings suggest that Herg1 participates in the proliferation and motility of OS cells and may serve as a potential therapeutic target for osteosarcoma patients.

Abstract
We quantify how and when extreme subpopulations emerge in a model society despite everyone having the same information and available resources – and show that counterintuitively these extremes will likely be enhanced over time by new social media algorithms designed to reduce division. We verify our analysis mathematically, and show it reproduces (a) the time-dependent behavior observed in controlled experiments on humans, (b) the findings of a recent study of online behavior by Facebook concerning the impact of ‘soft’ and ‘hard’ news, (c) the observed temporal emergence of extremes in U.S. House of Representatives voting, and (d) the real-time emergence of a division in national opinion during the ongoing peace process in Colombia. We uncover a novel societal tipping point which is a ‘ghost’ of a nearby saddle-node bifurcation from dynamical systems theory, and which provides a novel policy opportunity for preventing extremes from emerging.

Abstract
1. In order to increase the efficiency of generating transgenic chicken, this trial focused on two points: primordial germ cells (PGCs)transfection in vivo and a germline-specific promoter.2. In order to transfect PGCs in vivo, two plasmids (pZB-CAG-GFP, pCMV-ZB)were co-injected into chicken embryos via the subgerminal cavity at Hamburger and Hamilton (HH) stage 2-3 or via blood vessel at HH stage 13-14. Results showed that the percentage of GFP+ embryos, viability and hatching rate of embryos injected at HH stage 13-14 were significantly higher than that at HH stage 2-3.3. Two plasmid transposon systems were used for chicken embryo micro-injections. The donor plasmid, with a green fluorescent protein (GFP) reporter gene, was mediated by the ZB transposon. The helper plasmid was a transposase expression vector driven by the promoter of the chicken vasa homologue (Cvh) gene or Human cytomegalovirus (CMV) promoter. Results showed that 60.98% of gonads in Cvh group expressed GFP, which was 52.50% higher than seen in the CMV group. Only gonad tissue from the Cvh group showed any GFP signal, whereas both gonads and other tissues in the CMV group showed green fluorescence.4. The data suggested that ZB transposon-mediated gene transfer was efficient for transfecting PGCs in vivo; the Cvh promoter drove the transposase gene specifically in the germline and increased the efficiency of germline transmission. Blood vessels injection at HH stage 13-14 may be a more efficient route for PGCs transfection in vivo.

Abstract
Payments for ecosystem services (PES) may alter dynamics in coupled human and natural systems, producing reciprocal feedback effects on socioeconomic and environmental outcomes. As forests recover following China's two nation-wide PES programs, wildlife-related crop raiding has been increasingly affecting rural people's livelihoods. We evaluate the feedback effect of crop raiding on people's intention to convert their cropland plots into forests under different PES program scenarios in the Tianma National Nature Reserve. Increases in crop raiding, conservation payment amounts, and program duration significantly increased local people's intention to enroll their cropland plots in future PES programs. Our results suggest that a substantial portion of economic benefit from the current PES programs was offset by the feedback effect of crop raiding promoted by these programs. Therefore, such complex human-environment interactions should be incorporated into the design and evaluation of China's PES practices and other PES programs around the world.

Abstract
In the late 1990s, China initiated the Conversion of Croplands to Forest Program (CCFP) and the Ecological Welfare Forest Program (EWFP) based on the Payments for Ecosystem Services (PES) principle. Positive socioeconomic outcomes of the programs are essential for the long-term success of eco-environment conservation. However, there is lack of understanding of their longer-term (over 10 years) impacts on rural livelihoods. In this paper, we examine income distribution and inequality of rural households under CCFP and EWFP in rural Anhui, China after 12 years of program implementation. Results show that CCFP-participating households have higher income inequality than non-participants, while the EWFP does not have an significant effect. Local off-farm work and out-migration with remittances are the two principal income sources and both add to inequality. A regression-based decomposition of inequality shows that the CCFP indirectly alters livelihoods by increasing out-migration with remittances, but it also adds to inequality from shifting livelihoods to non-agricultural activities. Meanwhile, EWFP payments positively affect agricultural incomes and contribute 16% to agricultural income inequality. Finally, human capital, natural capital and physical capital all play important roles in generating income and inequality, but the factors affecting inequality from agricultural and non-agricultural activities are different.

We found that menatetrenone decreased the ratio of undercarboxylated osteocalcin to osteocalcin (ucOC/OC) and improved lumbar BMD compared with placebo based on the 18 studies assessed. However, its benefit in fracture risk control was uncertain. INTRODUCTION We performed a systematic review and meta-analysis of the efficacy and safety of menatetrenone in managing osteoporosis. METHODS PubMed, Cochrane Library, Embase, ClinicalTrials.gov , and three Chinese literature databases (CNKI, CBM, Wanfang) were searched for relevant randomized controlled trials (RCTs) published before October 5, 2017, comparing menatetrenone with other anti-osteoporotic drugs or placebo in treating osteoporosis. The pooled risk ratio (RR) or mean difference (MD) and 95% confidence interval (CI) were calculated using fixed-effects or random-effects meta-analysis. RESULTS Eighteen RCTs (8882 patients) were included. Pooled analyses showed that menatetrenone was more effective than placebo in improving lumbar bone mineral density (BMD) (five studies, N = 658, MD = 0.05 g/cm2, 95% CI 0.01 to 0.09 g/cm2) and decreasing ucOC/OC (two studies, N = 75, MD = - 21.78%, 95% CI - 33.68 to - 9.87%). Compared with placebo, menatetrenone was associated with a nonsignificantly decreased risk of vertebral fracture (five studies, N = 5508, RR = 0.87, 95% CI 0.64 to 1.20). Evidence on other anti-osteoporotic drugs as comparators was limited and revealed no significantly different effects of menatetrenone on BMD or fracture risks. Furthermore, compared with placebo, menatetrenone significantly increased the incidence of adverse events (AEs) (two studies, N = 1949, RR = 1.47, 95% CI 1.07 to 2.02) and adverse drug reactions (four studies, N = 6102, RR = 1.29, 95% CI 1.07 to 1.56). However, no significant difference in the incidence of serious AEs was found between menatetrenone and placebo. CONCLUSIONS Menatetrenone significantly decreases ucOC and might improve lumbar BMD in osteoporotic patients. However, its benefit in fracture risk control is uncertain.

Abstract
Rural out-migration has been a hallmark of socioeconomic development in China, but rapid economic development including deforestation also resulted in environmental degradation, leading to disastrous floods and droughts. In response, the Chinese government implemented Payments for Ecosystem Services (PES) programs for both environmental conservation and poverty alleviation, notably the Conversion of Cropland to Forest Program (CCFP) and the Ecological Welfare Forest Program (EWFP). In the context of a full model of the determinants of migration incorporating individual, household and community factors, we investigate the manner in which these programs influenced rural out-migration in a mountainous township in Anhui, China. Results show that the CCFP compensation for switching cropland to trees releases farm labor, leading to out-migration. Meanwhile, the EWFP compensation provides poor rural farmers with large areas of forest with sizable cash subsidies that reduces their motivation to migrate. Out-migration was also found to be affected by a number of individual, household and community characteristics.

Abstract
The rodent model has been largely used for understanding specific disease pathophysiology, with low cost and the large spectrum from genetic strains. Here, we present a diffuse speckle contrast analysis (DSCA) system to measure blood flow changes non-invasively in rat's thigh and paw during femoral arterial occlusion (FAO) surgery which is the procedure for inducing peripheral arterial disease. The blood flow index in rat's paw showed significant decrease according to arterial occlusion. Moreover, we analyzed cross-correlation between two measurement positions. The results showed the affinity with hemodynamic response. In conclusion, the DSCA system secured the intraoperative blood flow monitoring during FAO surgery in a rat model.
