Abstract
From land cover analysis, cropland expansion was a major driving factor for land use land cover changes in Nigeria from 2000 to 2020. This further highlights the food production needs in the country. While this land use change indicates a significant alteration in land cover, it was exigent to assess land suitability using a Multi-Criteria Decision Analysis (MCDA) combined with geospatial techniques to identify areas with agricultural suitability potential and to analyze cropland suitability. The results showed that the country had 8% of very high suitability, high suitability (25%), moderate suitability (29%), and marginal suitability (25%) croplands. However, low suitability accounts for 14% of the entire cropland. The spatial distribution of cropland suitability shows that most areas in the South East, South South, and South West, respectively, have the most suitable cropland as they meet the biophysical conditions for crop production, followed by the North Central regions, while most places in the North (North East and North West) have a higher share of moderate to low suitability. This study highlights the potential of the country to target localized self-sufficiency. Therefore, this study recommends using the cropland suitability map to launch food security programs across the six geopolitical zones to maximize their inherent environmental potentials to alleviate the country's food production needs.

Abstract
The growing population, the transition dietary towards animal-based products, and the preference for the brand of grass-feeding livestock are bringing increasing pressure on natural grasslands, especially for dry-land areas. The Xilingol League of China is famous for its free-range livestock product, however, overgrazing and herders' benefits damage are always serious issues for this semi-arid grassland region. This study focuses on the relationship between the supply of natural grassland and the consumption of free-range livestock in the Xilingol League, and this study employed the grassland carrying capacity as the index to judge the sustainability states and its trends of the local grass-feeding system. Satellite data production of net primary production was used for grassland production, statistical livestock data and the consumption model were used for actual forage consumption, and empirical key informant interview data were used to obtain a more comprehensive understanding. The results show that: (1) the natural grassland carrying capacity of the Xilingol League fluctuated, showing improvement from 2000 to 2021; (2) the grassland management needs to be more diversified in different regions with different natural conditions; and (3) while the demand for free-range, high-quality beef is increasing, attention should be paid to the carrying capacity of natural pastures and more consideration should be taken of the benefits of balancing the livelihood of herders, policy strategies, and the customers' preferences. Potential ways of doing this include employing technologies to improve livestock production, and further exploring and promoting the economic value of the free-range livestock and the geographical indication to get the economic-ecological win-win situation. The research framework and results would be beneficial to reveal the potential threats in pastoral areas and provide support for the optimization of the regional grass-feeding breeding system, especially in middle-income countries.

Abstract
Food security is critical for socioeconomic development. In grassland areas, inappropriate food consumption patterns can cause irreversible damage to vulnerable local ecosystems. This study aims to examine the household dietary diversity status and development trend over the past 20 years in Chinese herder communities. We draw on a cross-sectional dataset of 230 households involving 652 family members from the Xilin Gol Grassland areas in North China. Household dietary diversity was assessed using the household dietary diversity score (HDDS), which was calculated based on 12 food groups. Results show that HDDS increased from 3.74 in 1999 to 5.92 in 2019, with an annual average growth rate of 2.45% during the past 20 years. The increase in plant-based food scores made a major contribution to the HDDS improvement. The variations in household dietary diversity status between pastoral areas and agro-pastoral areas showed differences among different types of grassland in arid and semiarid transitional zones. It is worth paying more attention to monitoring the main impact factors that affect HDDS and how these changes might impact the local ecosystem, which will benefit regional sustainable development.

Abstract
Stable growth in grain production is a critical challenge to ensure food security in North China Plain (NCP), an area dominated by smallholder farming. Food production and security of NCP largely depend on how smallholders farm their land. This study took Ningjin County of the NCP as an example to describe the characteristics of crop planting structure and the changes in crop production based on household surveys, statistics, various documents, and literature by descriptive statistics, calculation of crop self-sufficiency, and curve fitting, and aimed to reveal crop security and the influencing factors of crop production at the household level. The results were as follows: (1) Wheat and maize sown area accounted for 61.69% and 47.96% of the total sown area of crops during 2000-2020, increasing at a rate of 3.42% and 5.93%, respectively. Their planted areas increased from 27.52% and 15.54% in 2000 to 47.82% and 44.75% in 2020, respectively. (2) The self-sufficiency rate of maize showed a significant upward trend and reached its peak in 2019. the self-sufficiency rate of wheat also showed an increasing trend, from 192.87% to 617.37%, which indicates that wheat and maize can meet food self-sufficiency and the per capita grain yield is in a safe state. (3) The trends on wheat yield and fertilizer initially grew, then decreased, closely resembling an inverted "U", while the maize yield showed a pattern of increasing first and then basically remaining stable, similar to an "S" shape. A turning point for fertilizer use (550 kg/ha) was identified, indicating the limits of fertilizer use to increase yield. The national agricultural production and environmental protection policies, continuous improvement of crop varieties, as well as the farmers' traditional practices have significant impacts on crop production. This study will enhance management practices for improved yield, which can support the integrated management of agricultural production in intensive agricultural areas.

Abstract
Ordos is an ecological fragile area in the upstream and midstream of the Yellow River and a component of the ecological security barrier on the northern frontier of China. With population growth in recent years, the contradiction between human beings and land resources has become increasingly prominent, leading to increased food security risks. Since 2000, the local government has implemented a series of ecological projects to guide farmers and herdsmen to transform from extensive production to intensive production, which has optimized the pattern of food production and consumption. It is necessary to study the balance between food supply and demand to evaluate food self-sufficiency. Here, we used the panel data from 2000 to 2020 collected based on random sampling surveys to reveal the characteristics of food production and consumption, the changes in food self-sufficiency rate and the dependence of food consumption on local production in Ordos. The results showed that food production and consumption dominated by grains have been increasing. The residents' diets were characterized by excessive consumption of grains and meat, and insufficient consumption of vegetables, fruits, and dairy foods. On the whole, the locality has achieved self-sufficiency, because the food supply exceeded the demand during the two decades. However, the self-sufficiency of different food types varied greatly, as some foods, such as wheat, rice, pork, poultry, and eggs, have not been self-sufficient. Due to the increased and diversified food demand of residents, food consumption became less dependent on local production and more dependent on food imported from the central and eastern China, which threatened local food security. The study can provide a scientific basis for decision-makers for the structural adjustment of agricultural and animal husbandry and the structural adjustment of food consumption, to ensure food security and sustainable utilization of land resources.

Abstract
Land use/cover change (LUCC) research occupies an important place in the study of global change. It is important for the ecological protection and long-term development of a place. Current research is lacking in the study of dynamic changes at the national level in Myanmar over long time periods and sequences. Quantitative research on the driving factors of LUCC is also lacking. This paper uses the GLC_FCS30 (Global Land-Cover product with Fine Classification System) dataset and socio-economic statistical data in Myanmar to conduct the study. The dynamic change process of LUC (land use/cover) was investigated using the land use dynamic degree, land use transfer matrix, and Sankey diagram. Principal component analysis was used to derive the main drivers of LUCC. The drivers were quantified using multiple linear stepwise regression analysis and specific factors were analyzed. The spatial scope of the study is Myanmar, and the temporal scope is 2000-2020. Results: (1) In 2020, the spatial distribution of LUC in Myanmar shows predominantly forests and croplands. Forests account for 56.64% of the country's total area. Agricultural land accounts for 25.59% of the country's total area. (2) Over the time scale of the study, the trend of LUCC in Myanmar showed significant shrinkage of evergreen broad-leaved forest and deciduous broad-leaved forest (a total shrinkage of -3.34 × 104 km2) and expansion of the other land types. (3) Over the time scale of the study, the dynamic changes in LUCC in Myanmar most occurred as an interconversion between two land types, such as between cropland and deciduous broad-leaved forest, evergreen broad-leaved forest and shrubland, deciduous broad-leaved forest and shrubland, evergreen broad-leaved forest and evergreen needle-leaved forest, and evergreen broad-leaved forest and deciduous broad-leaved forest. (4) The dynamics of LUC in Myanmar is mainly influenced by the socio-economic level of the country. Among them, the impact of agricultural level is the most obvious. Specifically, Myanmar's LUCC is mainly driven by urban population, urbanization rate, industrial value added, food production, and total population. Our research will enable the Myanmar government to make more scientific and rational land management and planning and to make more informed decisions. After understanding the basic situation of LUCC in Myanmar, the hydrological effects, biodiversity changes, and ecological service function changes due to land change in the region can be explored. This is the direction of future research.

Abstract
Anorectal malformations (ARMs) are the most common gastrointestinal malformations. miR-141-3p was obtained from whole-transcriptome sequencing, and Ub domain-containing protein 2 (Ubtd2) was predicted as the target gene. An ARM rat model was induced using ethylenethiourea. Fluorescence in situ hybridization and immunofluorescence were used to detect the spatiotemporal expression of miR-141-3p and Ubtd2, respectively. A dual-luciferase reporter assay confirmed their targeting relationship, and cell proliferation and apoptosis were investigated after transfection in the intestinal epithelium (IEC-6). Additionally, western blotting and co-immunoprecipitation were used to examine the protein levels and the endogenous binding relationship. miR-141-3p was downregulated in the ARM group, whereas Ubtd2 increased and colocalized with TUNEL-positive cells. After miR-141-3p inhibition, protein expression of USP5 and β-catenin was affected via Ubtd2, and USP5 could bind to both Ubtd2 and β-catenin. Flow cytometry analysis and caspase 3/7 staining demonstrated that downregulated miR-141-3p promoted cell apoptosis through Ubtd2. In summary, targeting Ubtd2 decreased in miR-141-3p and promoted apoptosis of intestinal epithelium and regulated β-catenin expression. This may cause aberrant apoptosis during hindgut development and mediate the imbalance of β-catenin signaling in the cloaca, further affecting the occurrence of ARMs.

Abstract
Changes in land use in an agro-pastoral region affect the delivery of ecosystem services. The trajectory of future land use change and its impacts on human society are not yet well understood, which poses a challenge to efforts to balance the socioeconomic development with the supply of ecosystem services. Taking the Hunshandake region for a case study, we developed four land use scenarios, and projected the future land use patterns under those scenarios using the GeoSOS-FLUS model. We then assessed the ecosystem service values (ESV) using a modification of the equivalent-coefficient method that accounts for differences in net primary production, and explored the impacts of land use change on ESV from 2018 to 2030. We found important land use conversions among the forest, grassland, and cropland uses, mainly in the southern part of our study area. The presence of ESV change hotspots and cold spots suggested that the changes were clustered in the southeastern part. The ESV gain and loss matrix showed that the land use changes under a scenario that prioritized ecosystem services and the comprehensive development scenario increased ESV from 2018 to 2030 with the conversion of cropland to forest. Our results provide important knowledge to inform land use decisions and facilitate sustainable development in the Hunshandake region.

Abstract
The Agro-Pastoral Zone of Northern China (AZNC) is an ecologically fragile zone. It is a challenge to create scientifically sound plans for environmental conservation and agro-pastoral development due to the lack of future evolution prediction, and analysis of biocapacity (BC) and landscape characteristics. Using the Globeland30 dataset from 2000 to 2020, this study simulated 2030 land use/land cover (LULC) scenarios, and analyzed the future evolution of BC and landscape patterns. The results show that: (1) The Logistic and CA-Markov models can reasonably simulate the LULC changes in the research area, with ROC indices over 0.9 and Kappa approaching 0.805, after considering the driving factors such as physical geography, regional climate, and socio-economic development. (2) From 2000 to 2030, the spatial distribution pattern of LULC does not change significantly, and cultivated land, grassland, and forest are still the dominant land types in the research area. The regional BC exhibits an increasing trend (+4.55 × 106 gha/a), and the spatial distribution pattern of BC is similar to that of LULC. (3) Changes in land miniaturization, landscape fragmentation, and decreased aggregation can be seen in the entire AZNC and specific land categories, including cultivated land, grassland, and forest. The study provides suggestions for formulating the AZNC's future ecological protection and agro-pastoral development strategies, and guidance for the LULC simulation in other agro-pastoral zones.

Abstract
Food consumption is the vital connection between human beings and natural resources. Our research explores the characteristics and drivers of food consumption patterns within Mongolian grasslands with a vulnerable ecology and environment. Food consumption data were obtained via a household questionnaire survey, and the emergy method was applied to analyze the food consumption characteristics in different grassland areas. This led to the following results: (1) The total per capita food consumption in different banners showed greater consumption and higher percentage of animal-based food in regions farther north. (2) From south to north, the main meat consumption in different banners varied, the predominant meat type consumed in Taibus was pork, that in Zhenglan was mutton, and that in West Ujimqin was beef. The farther north, the more fruits and vegetables were consumed. (3) The characteristics of food consumption in different areas were influenced by a series of factors, including social, economic, and ecological ones. Local food supply and disposable income were the main factors that had important effects on food consumption structure, as these two factors provided accessibility to foods for consumption.

Abstract
Objective: To explore the application value of chromosome karyotype analysis, chromosomal microarray analysis (CMA) and whole exome sequencing (WES) in prenatal diagnosis of isolated corpus callosum abnormality (CCA) fetus. Methods: Fetuses diagnosed with isolated CCA by ultrasound and MRI and receiving invasive prenatal diagnosis in Guangzhou Women and Children's Medical Center and Qingyuan People's Hospital from January 2010 to April 2021 were selected. Karyotype analysis and/or CMA [or copy number variation sequencing (CNV-seq)] were performed on all fetal samples, and WES was performed on fetal samples and their parents whose karyotype analysis and/or CMA (or CNV-seq) results were not abnormal. Results: Among 65 fetuses with isolated CCA, 38 cases underwent karyotype analysis, and 3 cases were detected with abnormal karyotypes, with a detection rate of 8% (3/38). A total of 49 fetuses with isolated CCA underwent CMA (or CNV-seq) detection, and 6 cases of pathogenic CNV were detected, the detection rate was 12% (6/49). Among them, the karyotype analysis results were abnormal, and the detection rate of further CMA detection was 1/1. The karyotype results were normal, and the detection rate of further CMA (or CNV-seq) detection was 14% (3/21). The detection rate of CMA as the first-line detection technique was 7% (2/27). A total of 25 fetuses with isolated CCA with negative results of karyotyping and/or CMA were tested by WES, and 9 cases (36%, 9/25) were detected with pathogenic genes. The gradient genetic diagnosis of chromosomal karyotyping, CMA and WES resulted in a definite genetic diagnosis of 26% (17/65) of isolated CCA fetuses. Conclusions: Prenatal genetic diagnosis of isolated CCA fetuses is of great clinical significance. The detection rate of CMA is higher than that of traditional karyotyping. CMA detection could be used as a first-line detection technique for fetuses with isolated CCA. WES could increase the pathogenicity detection rate of fetuses with isolated CCA when karyotype analysis and/or CMA test results are negative.

Abstract
Fluoride agents hold promise for the repair and prevention of caries lesions, but their interaction with enamel is often hampered and diminished because of the dynamic wet environment in the oral cavity, which affects the efficacy of fluoride delivery and limits treatment success. We herein developed a mussel-inspired wet adhesive fluoride system (denoted TS@NaF) fabricated by the self-assembly of tannic acid (TA), silk fibroin (SF), and sodium fluoride (NaF). TS@NaF demonstrated remarkable biological stability and biocompatibility, showed reliable wet adhesion, released fluoride ions (F−) topically, and induced significant deposition of calcium fluoride (CaF2) onto enamel in vitro. Furthermore, TS@NaF provided an anticaries effect in vitro and induced a detectable increase in enamel mineral density. Advanced fluoride-releasing bioadhesives are therefore promising candidates for caries prevention and highlight the great potential of mussel-inspired dental materials in clinical applications.

Abstract
Several studies have shown that smallholder farmers produce most of the food in low-income and developing countries and form the backbone of the country’s food supply. This study examines the extent these smallholder farmers in Nigeria can put the country on the path to self-sufficiency and ensure satiety for household food consumption through their local production. The study also examines food production and their resulting yield based on crop production and harvested area, as well as the percentage of crops produced for food or other purposes. The results show that production of rice, sorghum, soybean, cassava, and yam is low; and their corresponding yields are declining, with the exception of maize, although the harvested area increased from 2015 to 2018. As it is, the findings are a clear indication of inadequate per capita food supply due to low food production, especially for cereals. The study suggests closing the yield gap specifically for cereals, limiting post-harvest losses, and finding a sustainable balance between the uses of major food crops for animal feed to reduce pressure on land resource use. The different states production performance requires special attention to harness the agricultural potential of each geopolitical zone. Lastly, dry-season cultivation should be encouraged through irrigation to enable harvesting two-times in a year. The study offers useful approaches to assess the contribution of local farmers to the food supply of a growing population and provides suggestions for the government, stakeholders, and the international community willing to collaborate and invest in the agricultural sector.

Abstract
Although cultural ecosystem services (CES) are greatly valued by diverse stakeholders, the full range of CES provided by a landscape is notoriously difficult to estimate. The resulting lack of objective norms for CES may lead to the loss of the multiple non-material factors that contribute to how a landscape is valued and experienced. This is especially true under ecological restoration, which could sharply change how people experience landscapes. Therefore, our aim in this study was to identify and analyze the CES that arise from people's interaction with their landscape, focusing specifically on the influences of different ecological restoration strategies. We carried out semi-structured interviews with the residents of villages in the Xilin Gol League, Inner Mongolia, China. Regarding the implementation of ecological restoration measures, the people living in typical pastoral zones would be most affected by these measures because their main livelihood (animal husbandry) depends strongly on grasslands. Our results demonstrated that human perception of the CES provided by landscapes is affected not only by the factors related to an individual's cultural worldview (e.g., ethnicity, age, education) but also by the utility of landscape features, which are reflected in the individual's landscape dependence (occupation). Our research provides a cultural perspective for aspects of local well-being in addition to ecological and economic targets. Understanding these other aspects is critical for implementing sustainable ecological restoration.

Abstract
Food resource is an important bond that connects human beings and nature. In this study, we investigated the changes in food consumption and nutrition intake in Kazakhstan from a spatial and temporal perspective, from 2001 to 2018. The data were obtained from the Bureau of Statistics, international organizations and our social interview work. After the start of the 21st century, it was found that per capita food consumption significantly increased; however, the consumption of crop, vegetables and milk decreased. Per capita meat consumption was similar in both urban and rural areas. However, some food consumption showed differences between urban and rural areas. Changes of food consumption quantity and structure also had some effects on nutrient intake and the proportion of nutrients. Per capita energy intake in the national, urban and rural areas all increased remarkably. The energy intake changes in eastern states increased much more than that in western states. Protein intake in rural and urban areas was similar; however, the gap between carbohydrates and fat intake in urban and rural areas increased. The intake of protein, carbohydrates and fat in different states showed the same trend. Food consumption and nutrition intake are affected by economic, social and ecological factors.

Abstract
Research on food consumption in Nigeria has mainly focused on food intake, household diversity, and purchasing power. We investigated a knowledge gap for food consumed by households and the land requirements for food resulting from household consumption patterns. The food consumed and the household size determine the land requirement for food. Therefore, a quantity-based analysis and a land demand methodology were applied to derive household food quantity and land requirements for food respectively. The results show that a greater percentage of household income is spent on cereals and starchy roots as the main source of calories and that cowpea is a secondary food option for households. In addition, households are changing their dietary intake from rice to maize and rice to cassava and yams as a cheaper alternative and experts' measurements of food security at the household level indicates that households in our study are moderately food insecure. Other findings show that the country's specific and per capita land requirements for food have gradually increased between 2000 and 2018. Across the six geopolitical zones, Northern regions with higher populations have high land requirements for food, especially for rice and maize (cereals), while Southern regions have high land requirements for cassava and yams (starchy roots) due to their respective consumption and household sizes. In addition, from our study, the land requirements for food show the actual cropland area of South South fed 5000 households. Consequently, a scenario analysis shows that the land requirements for food in our study exceeds the entire geographical area of Nigeria. Therefore, continued population growth without improved living standards and adequate food production output per hectare will further exacerbate food insecurity and land shortage in Nigeria.

Abstract
OBJECTIVE The aim is to perform a network meta-analysis to evaluate the effect of different Chinese medicines combined with Western medicine treatment (WMT) on the 28-day mortality of patients with sepsis. MATERIALS AND METHODS We searched multiple databases for randomized controlled trials (RCTs), using keywords such as sepsis, Shenfu, Shenmai, Shengmai, Dahuang Fuzi, Xuebijing, and mortality. The databases we searched included the China Knowledge Network (CNKI), Wanfang database, the Chinese scientific journal database (VIP), the Chinese biomedical literature database (CBM), PubMed, Embase and Cochrane. The collection time was from inception through September 22, 2020. Two researchers independently screened the articles, extracted data, and assessed the quality of the evidence. Stata15 was used for network meta-analysis, and Excel was used to summarize the list of adverse reactions. RESULTS Twenty-nine studies with a total of 3201 patients were included in this study. Combined with WMT, Shenfu injection [OR = 0.63, 95% CI = (0.47, 0.83)] and Xuebijing injection [OR = 0.71, 95% CI = (0.52, 0.96)] can significantly reduce 28-day mortality among patients with sepsis, while Shenmai injection [OR = 0.40, 95% CI = (0.16, 1.03)] and Dahuang Fuzi decoction [OR = 1.00, 95% CI = (0.48, 2.10)] cannot significantly improve on the 28-day mortality. The efficacy ranking is as follows: Shenmai group (level of evidence: low) > Shenfu group (level of evidence: low) > Xuebijing group (level of evidence: very low) > WMT group > Dahuangfuzi group (level of evidence: very low). CONCLUSIONS Combined with WMT, Shenfu injection or Xuebijing injection can reduce the 28-day mortality among patients with sepsis. The Shenfu group had the best effect on outcomes, and its level of evidence was higher than that of the Xuebijing group.

Abstract
Objective: To evaluate the value of whole exome sequencing (WES) in prenatal clinical application. Methods: A total of 1 152 cases of congenital abnormal [including structural malformation, nuchal translucency (NT) thickening and intrauterine growth restriction] with traditional prenatal diagnosis [including G-band karyotype analysis and chromosome microarray analysis (CMA)] negative were analyzed. The congenital abnormal fetuses were divided into retrospective group and prospective group according to the time of WES detection, that is whether the pregnancy termination or not. According to the specific location of fetal malformation and their family history, the cohort was divided into subgroups. The clinical prognosis of all fetuses were followed up, and the effect of WES test results on pregnancy decision-making and clinical intervention were analyzed. According to the follow-up results, the data of fetuses with new phenotypes in the third trimester or after birth were re-analyzed. Results: Among 1 152 families who received WES, 5 families were excluded because of nonbiological parents. Among the remaining 1 147 families, 152 fetuses obtained positive diagnosis (13.3%,152/1 147), including 74 fetuses in the retrospective group (16.1%,74/460) and 78 fetuses in the prospective group (11.4%,78/687). In fetuses with negative CMA and G-band karyotype analysis results but new phenotypes in the third trimester or after birth, the positive rate by WES data re-analysis was 4.9% (8/163). A total of 34 (21.3%, 34/160) fetuses were directly affected by the corresponding positive molecular diagnosis. Among 68 cases of live births with diagnostic variation grade 4, 29 cases (42.7%, 29/68) received appropriate medical intervention through rapid review of WES results. Conclusions: WES could increase the detection rate of abnormal fetuses with negative G-banding karyotype analysis and CMA by 13.3%. Prenatal WES could guide pregnancy decision-making and early clinical intervention. It might be an effective strategy to pay attention to the special follow-up of the third trimester and postnatal fetus and to re-analyze the WES data.

Abstract
The imbalance in the supply and demand for resources is a thorny issue that many countries have to face. Food is a basic resource throughout the world. Understanding the exact situation of food production and consumption is an important foundation for sustainable development. This paper aims to explore the quantity and pattern changes in food production and consumption in Kazakhstan. This can reflect the level of residents' standard of living and the situation of natural resource use. This paper focuses on the quantitative relationship between animal-based food and plant-based food and the tendency towards changes in urban and rural residents' food production and consumption in Kazakhstan based on the emergy analysis method. The data of food production and consumption were mainly obtained from the official statistics of the Food and Agriculture Organization (FAO), the World Bank, Statistical Commission of the Ministry of National Economy of Kazakhstan, and literature. The research results showed that, over time, Kazakhstan residents' food consumption patterns have become more varied, and the proportion of meat consumption to total food consumption has increased. Although the rural per capita food consumption is significantly different from that of urban residents, this gap decreased in 2019. In Kazakhstan, the consumption of several types of food still relies on imports. Food production and consumption are affected by economic, social, and ecological factors. The results of this research can provide scientific support for reasonable and sustainable production and consumption strategies in Kazakhstan.

Abstract
OBJECTIVE To explore the prognostic value of the morphology of tumor invasion front (TIF) in Intrahepatic Cholangiocarcinoma (ICC). PATIENTS AND METHODS Seventy-four ICC patients with complete clinicopathological data and follow-up information were enrolled in our study. The most typical morphology of TIF of each case will be classified as low-grade group or high-grade group after evaluation by two pathologists. The clinicopathological characteristics, disease-free survival (DFS), and overall survival (OS) were compared between the two groups. RESULTS A total of 26 (35.3%) patients were assigned to low-grade group, while 48 (64.7%) patients were assigned to high-grade group. High-grade group was associated with higher CA19-9 (p=0.032), poor differentiation (p=0.050), larger tumor diameter (p=0.016), advanced T staging (p=0.048), and higher incidence of lymph node (LN) metastasis (0.014). No significant associations were found in demographic and clinical characteristics between the two groups. On multivariable analysis, high-grade group was a significant independent predictor of worse DFS (HR=0.433, 95% CI=0.235-0.800, p=0.002) and OS (HR=0.363, 95% CI=0.187-0.704, p=0.003). CONCLUSIONS High-grade morphology of TIF was an independent prognostic factor of ICC.

Abstract
Acute abdomen, abdominal trauma, gastrointestinal bleeding and gastrointestinal tumors are the main conditions that are routinely treated in gastrointestinal surgery department with high incidence and critical condition. These conditions need emergency or selective operations. During the outbreak of the coronavirus disease 2019 (COVID-19), it's a great challenge for us to meet the patients' requirement under the situation. As the COVID-19 was brought under control in China, the Department of General Surgery in Nanfang Hospital resumed regular medical services gradually. Based on our clinical practice, the four major measures of strengthening pre-hospital screening, perioperative prevention and control, medical staff protection, and ward management were adopted. These main measures include the strict implementation of the appointment system and triage system before admission; the conduction of epidemiological and preliminary screening of viral nucleic acids; the chest CT examination during the perioperative period to re-screen COVID-19; the reduction of the risk of droplets and aerosol transmission; the minimally invasive surgery combined with enhanced recovery program in order to reduce patient's susceptibility and shorten the length of postoperative hospital stay; the reinforcement of specific infection control training for medical staff; the strict implementation of hierarchical protection; the establishment of gastrointestinal surgery prevention and control system; the rehearsal of emergency exercise; the installation of quarantine wards; the screening and management of family care-givers; the strict disinfection of environment and materials. Our preliminary practice shows that following the work guidelines issued by the Guangdong Province COVID-19 Prevention and Control Office and adopting precise management strategies in combination with the specific clinical features of gastrointestinal surgery, it is possible to safely resume regular care for the patients and comply to epidemic control at the same time.

Abstract
OBJECTIVE Embryonic stem cells (ESCs) mainly originate from totipotent cells in early-stage of mammalian embryo and could proliferate in a manner of un-limitation. This study aimed to investigate roles of Axin2 in proliferation of ESCs and explore the associated mechanisms. MATERIALS AND METHODS Axis inhibition protein 2 (AXIN2) over-expression (LV5-AXIN2) and AXIN2 RNA interfere (LV3-AXIN2-RNAi) vectors were structured and transfected into H9 cells. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) was used to evaluate cell proliferative activity. Flow cytometry analysis was employed to measure apoptosis of H9 cells. AXIN2, β-catenin, transcription factor 4 (TCF4), c-myc, c-jun and Cyclin D mRNA levels and protein expressions were determined using quantitative real-time PCR (qRT-PCR) and Western blotting assay. RESULTS LV5-AXIN2 and LV3-AXIN2-RNAi were successfully structured with higher transfecting efficacy. AXIN2 gene silencing remarkably increased proliferative activity and AXIN2 treatment significantly induced apoptosis of H9 cells, comparing with blank vector group (p<0.05). AXIN2 gene silencing significantly enhanced B-cell lymphoma-2 (Bcl-2) expression and remarkably inhibited cleaved caspase-3 expression comparing to that in blank vector group (p<0.05). AXIN2-RNAi treatment significantly enhanced and AXIN2 over-expression significantly reduced β-catenin and TCF4 expression, comparing to that in blank vector group (p<0.05). AXIN2 gene silence activated down-stream molecules of Wnt/β-catenin signaling pathway, including c-jun, c-myc, and Cyclin D1 (p<0.05). CONCLUSIONS AXIN2 gene silencing reduced apoptosis by regulating mitochondria-associated apoptosis signaling pathway and enhanced proliferation by modulating molecules in Wnt/β-catenin signaling pathway. Therefore, targeting of aberrant apoptosis and AXIN2 might be a novel clinical strategy to inhibit aging and enhance self-renewal of ESCs.

Abstract
Sustainable land use is a fundamental research field for land use planning. However, regional policymakers often lack access to the theoretical impacts that a land use policy might have on local development, especially in remote agricultural areas. Furthermore, knowledge exchange is important, especially in the context of globalization. This research employed the Framework of Participatory Impact Assessment and household surveys to combine multilevel stakeholders and comprehensively assessed the impacts of different land management scenarios on land use functions (LUFs) and local sustainable development. We completed this comparative study in typical remote agricultural areas in Godagari upazila of Bangladesh, Guyuan of China and Noto of Japan, which all have gradient differences in terms of their economic and social aspects, natural conditions and main land use issues. The selected scenarios were business as usual, increase in agricultural input and reform of rural development mode. The main conclusions are as follows: (1) the farmers at the three study sites all showed a decreasing dependence on their land and a relevant level of stress on environmental LUFs, but the rooted reasons were different and even opposing; (2) scenarios with a high aggregate impact on LUFs might not enable a sustainable development model, and the assessment of land management measures should consider the balance among environmental, economic and social dimensions; and (3) land use and management practices should be conducted with consideration of local conditions, and protecting agricultural development and enacting appropriate agricultural reforms could revitalize local agricultural development. The results revealed the demand for location-specific land management practices and underlined the knowledge of agricultural management on an international scale.

Abstract
The Three Rivers Source Region, in the central Qinghai-Tibet Plateau, has a sensitive and fragile ecological environment. Adverse changes in climate and human activities have degraded the grassland ecosystems. To mitigate or reverse the degradation, alleviate rural poverty, and stimulate economic development, ecological restoration projects have been implemented. In the present study, our goal was to assess the ecological and socioeconomic effects of these programs based on land-use change, grassland NPP, and household surveys. Household data were collected using structured questionnaires in 11 villages from three counties, with average elevation above 3773 m asl. We found that the grassland degradation had been mitigated, especially after the implementation of ecological restoration programs since 2005 in a regional nature reserve in Qinghai Province. Household income depends strongly on the region's natural resources, so the grassland ecosystems are still at risk of unsustainable use. A household that understood the effects of the ecological restoration programs and had received training to participate in the programs was more willing to participate in future programs. Our findings suggest that for successful restoration, it is essential to help residents of the study area thoroughly understand the ecological restoration programs and learn the restoration techniques before implementation of such programs. This is because the participation of the residents depended strongly on both their income and their satisfaction with the ecological restoration programs.

Abstract
Landscape change caused by ecological restoration projects has both positive and negative influences on human livelihoods, yet surprisingly little research on the cultural consequences of ecological restoration in agricultural landscapes has taken place. Cultural consequences can be captured in the ecosystem services framework as cultural ecosystem services (CES). However, assessment and valuation of these services to support decision-making for this essential ecosystem is lacking. To help fill this gap, we assessed the opinions of Chinese rural communities about CES and the changes in their perception under the Grain for Green program (GFG), a nationwide program to relieve the pressure on ecosystems (soil erosion and land degradation) by converting cultivated land or barren land on steep slopes into grassland and forests. We used Guyuan City in China's Ningxia Hui Autonomous Region as a case study, using a workshop to identify the CES provided by the agricultural landscape, followed by semi-structured household interviews to quantify perceptions of these CES. We found that all eight CES types identified by the workshop were perceived by the rural communities. Reforestation changed their perceptions of CES directly due to land cover change and indirectly due to the resulting economic changes and migration of mostly young workers in search of better jobs. Cultivated land was perceived as more important than forest for CES provision. In addition, residential areas were perceived as providing significant CES because of local traditions that produce close and highly social neighborhood bonds in agricultural landscapes.

Abstract
Ecosystem services are closely linked to human welfare. The flow of ecosystem service can establish spatio-temporal relationships between ecosystem service provision areas (SPAs) and service beneficiary areas (SBAs). In this study, the Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model was used to simulate the spatial flow path of the wind erosion prevention (WEP) service in Yanchi County. The frequency at which the simulated trajectories passed through each grid cell was used as a proxy for spatio-temporal disparities in SBAs, and the distribution of benefitting land cover, population, and gross domestic product (GDP) reflected the effects of the WEP flow. The flow paths of the Yanchi County WEP in 2010 mainly extended to eastern and central China, North Korea, South Korea, Japan, Mongolia, and eastern Russia, and were more intensive and longer in spring and winter than in autumn and winter. The SBAs covered an area of 1153.2 × 10⁴ km² in 2010, with dominant service beneficiary areas (DSBAs) comprising 185.1 × 10⁴ km² and accounting for 16.1% of the total beneficiary area of the year. The areas through which the flow paths passed with a high frequency (≥10%) were mainly located in Shaanxi, Shanxi, Henan, western Shandong, Hebei, Beijing, and northern Hubei, and the spatial scale of these areas varied, demonstrating obvious seasonal changes, and was the largest in spring. The benefitting land cover was mainly cropland across all of the SBAs, with one billion benefitting people (accounting for 77.11% of the total population of China) associated with a gross domestic product (GDP) of 26.8 trillion RMB (Chinese currency; as of 2018-06-22, 6.497 RMB = US $1, accounting for 87.90% of the total GDP of China). Furthermore, the population and socio-economic development in the DSBAs (21 million people and 0.53 trillion RMB GDP) were no longer affected by wind erosion from Yanchi County. This study revealed the spatio-temporal disparities of the SBAs of WEP in Yanchi County from an ecosystem services flow perspective and provides a scientific and effective basis for policymakers to perform standard ecological compensation accounting and to formulate ecological protection policies.

Abstract
OBJECTIVES To evaluate the diagnostic yield of prenatal whole exome sequencing (WES) for monogenic disorders in fetuses with structural malformations and normal results on cytogenetic testing, and to describe information on pathogenic variants that is provided by WES. METHODS Karyotyping, chromosomal microarray analysis (CMA) and WES were performed sequentially on stored samples from a cohort of 3949 pregnancies with fetal structural abnormalities detected on ultrasound and/or magnetic resonance imaging, referred between January 2011 and December 2015. Diagnostic rates of the three techniques were investigated overall, for phenotypic subgroups and for proband-only vs fetus-mother-father samples. Information on pathogenic variants was identified by WES. RESULTS Overall, 18.2% (720/3949) of fetuses had an abnormal karyotype. Pathogenic copy number variants were detected on CMA in 8.2% (138/1680) of fetuses that had a normal karyotype result. WES performed on a subgroup of 196 fetuses with normal CMA and karyotype results revealed the putative genetic variants responsible for the abnormal phenotypes in 47 cases (24%). The molecular diagnosis rates for fetus-mother-father and proband-only samples were 26.5% (13/49) and 23.1% (34/147), respectively. Variants of uncertain significance were detected in 12.8% (25/196) of fetuses, of which 22 were identified in the fetal proband-only group (15%; 22/147) and three in the fetus-mother-father group (6.1%; 3/49). The incidental finding rate was 6.1% (12/196). CONCLUSIONS WES is a promising method for the identification of genetic variants that cause structural abnormalities in fetuses with normal results on karyotyping and CMA. This enhanced diagnostic yield has the potential to improve the clinical management of pregnancies and to inform better the reproductive decisions of affected families. Copyright © 2017 ISUOG.

Abstract
This study was conducted to evaluate the effects of supplemental rumen-protected capsule (RPC) on animal performance, serological indicators, and serum heat shock protein 70 (HSP70) of lactating Holstein cows under heat stress (HS). During summer months, 30 healthy multiparous lactating Holstein cows with a parity number of 3.1 ± 0.44, 70 ± 15 d in milk, an average body weight of 622 ± 62kg, and an average milk yield of 32.28 ± 0.96kg/d, were used. The cows were randomly allocated to two groups: a control group and an RPC-supplemented group (0.13373kg K2SO4, 0.02488kg vitamin C, 0.021148kg niacin, and 0.044784kggamma-aminobutyric acid per cow). During the 42-d experiment, ambient air temperature and relative humidity inside and outside the barn were recorded hourly every day for the determination of temperature-humidity index (THI). Milk and blood samples were collected every week, and body weight and body condition scoring were measured on day 0. Based on the THI values, the animals had moderate HS. On day 42, the RPC group had lower HSP70, adrenocorticotropic hormone (P = 0.0001), lactate dehydrogenase (P = 0.0338), and IL-6 (P = 0.0724) levels than the control group, with no significant differences in creatine kinase, glucocorticoid, or IL-2 levels. Milk yield, energy-corrected milk, and dry matter intake were higher in RPC than in the control group (P = 0.0196). There were no significant differences in milk fat or daily protein levels between the two groups; however, daily protein and milk fat levels were higher in the RPC group than in the control group (P = 0.0114 and P = 0.0665, respectively). Somatic cell counts were no different between the two groups. In conclusion, RPC may alleviate HS and improve dairy cow performance.

Abstract
Background MicroRNAs (miRNAs) have been shown to be involved in the initiation and progression of cancers in the literature. In this study, we aimed to evaluate the clinicopathological role of miR-17 in breast cancer. Materials and methods The expression of miR-17 was measured in 132 breast cancer tissues and paired adjacent normal tissues by using real-time quantitative polymerase chain reaction. The association between miR-17 expression levels and clinicopathological parameters was also analyzed. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and flow cytometry assays were used to investigate the role of miR-17 in the regulation of breast cancer cells. Results The expression of miR-17 was remarkably increased in breast cancer tissues and cell lines. Clinical association analysis revealed that a high expression of miR-17 was prominently associated with poor survival time in breast cancer. Overexpression of miR-17 promoted cell proliferation and induced tumor growth. Conclusion Our findings clarified that the upregulation of miR-17 played a vital role in breast cancer progression and suggested that miR-17 could be used as a prognostic biomarker for breast cancer.

Abstract
OBJECTIVE To investigate the application of fetuses with talipes equinovarus(TE)using chromosomal microarray analysis(CMA)technology. METHODS From May 2012 to June 2015, 54 fetuses were found with TE and with or without other structural anomalies by prenatal ultrasound. Karyotyping was taking for them all, and the fetuses with normal karyotypes took another CMA test. The data were analyzed with CHAS software. Finally all the cases were followed up to know about their pregnancy outcomes. RESULTS One of the 54 cases was detected with abnormal karyotype which was trisomy 18(2%, 1/54). CMA was undertaken to the remaining fetuses, they were divided into 2 groups, including isolated TE group(n= 38)and complex TE group(n=15). The detection rate of clinical significant copy number variations(CNV)by CMA was 11%(6/53), while isolated and complex TE group were 5%(2/38)and 4/15, respectively(P= 0.047). Of the 53 cases, 51 cases were successfully followed up. Eleven cases were found without TE after birth, and the false positive rate(FPR)of TE was 22%(11/51). CONCLUSIONS Whole-genome high-resolution CMA increased the detection rate by 11% in fetuses with TE. With the FPR and the detection rate of the clinical significant CNV of 2 groups, whole-genome CMA could be recommended to the fetuses with complex TE group but normal karyotypes. A series of ultrasonic tests should be suggested to the isolate TE group, while with the abnormal ultrasound, fetuses would be suggested to have CMA test for decreasing the rates of invasive prenatal diagnosis and FPR.

Abstract
OBJECTIVE To determine the influence of free invasive prenatal testing on the uptake of non-invasive prenatal testing (NIPT). STUDY DESIGN Over a 2-year period at a Chinese tertiary prenatal diagnostic unit, women at risk of fetal trisomy were given the option of NIPT or invasive prenatal testing. Invasive prenatal testing was offered free of charge to women with a local Hukou (household registration); however, women without a local Hukou were charged for invasive prenatal testing. Both women with and without a local Hukou were charged for NIPT. RESULTS During the first year, 2647 women with a positive trisomy 21 screening test were referred (474 women with a local Hukou and 2173 women without a local Hukou). Only 1.6% of the women with a local Hukou underwent NIPT, while this proportion was 20.6% in the women without a local Hukou. During the second year, the price of NIPT was reduced. The total number of women referred was 3047 (502 women with a local Hukou and 2545 women without a local Hukou). The uptake of NIPT in women without a local Hukou doubled, but the uptake of NIPT remained stable in women with a local Hukou. CONCLUSION The financial impact on the uptake of NIPT should not be underestimated.

Abstract
Thanatophoric dysplasia (TD) is the most frequent form of lethal skeletal dysplasia. Prenatal diagnosis is commonly accomplished in the second-trimester scan, but occasionally TD is found to be associated with increased nuchal translucency (NT) at first-trimester screening for aneuploidies. TD may not be clearly distinguished from the other skeletal dysplasias. A definite diagnosis can be established by molecular genetic analysis to find out the abnormal mutations in the fibroblast growth factor receptor 3 (FGFR3) gene. We reported a case of TD type 1 detected by first-trimester NT measurement, and confirmed by molecular analysis of FGFR3 gene using high-resolution melting analysis.

Abstract
The aim of this study was to describe the experience of transabdominal chorionic villus sampling (CVS) at a mainland Chinese hospital. During a 7-year period, 1,172 pregnant women chose to have CVS for prenatal diagnosis. Details and outcome of all of these cases were reviewed. The median maternal age was 29 years (range 19-45). The median gestational age was 12 weeks (range 10-14). Fetal karyotyping and thalassaemia couples were the main indications (97.2%). Overall, 112 (9.7%) chromosomal abnormalities were identified. There were 91 (7.8%) major chromosomal abnormalities, including autosomal trisomy in 70 patients, sex chromosomal abnormalities in 17, triploidy in two and unbalanced chromosomal rearrangement abnormality in two. Additionally, 137 fetuses with severe thalassaemia syndrome were found, including 86 homozygous β-thalassaemia, and 51 homozygous α-thalassaemia or non-deletional haemoglobin H disease. The procedure failed to obtain an adequate sample in four (0.3%) patients. There were 229 pregnancies terminated for medical indications after CVS. There were three (0.3%) potentially procedure-related fetal losses. CVS is a safe and reliable prenatal diagnostic technique. It should be one of the options available to pregnant women who require prenatal diagnosis.

Abstract
Grassland ecosystems, as the basic natural resources in the Inner Mongolia Autonomous Region, are becoming increasingly sensitive to human intervention, leading to deterioration in fragile ecosystems. The goal of this study was to describe the restoration policy-oriented adoptive changes to basic household consumption patterns of food, fuel, and water, and their spatial distribution by grassland types in the region. Basic household consumption data were collected in the meadow steppe (Hulun Buir), typical steppe (Xilin Gol), and semi-desert steppe (Ordos) ecosystems using structured questionnaires administered to 209 herders and farmers. In 2010, the householders’ intake comprised a low amount of agri-crops, including staple foods, vegetables and fruit with a high amount of meat, which still dominated the patterns of food consumption. However, the number of households preferring this pattern is decreasing and higher amounts of agri-crop and lower amounts of meat consumption pattern is increasing. From 1995 to 2010, fuel consumption patterns changed from being dominated by bio-fuels (dung) to being dominated mainly by electricity and gas. However, bio-fuel remains a major energy source for daily life in the meadow steppe ecosystem. In all three surveyed grassland types, the use of coal, electricity and gas increased from 1995 to 2010. The source of domestic water in all three surveyed areas is from groundwater, with an increasing trend to use tap water from a public supply rather than from privately owned wells.
