Abstract	Objectives: To provide reference basis for reducing the mortality for children under 5 years old and promote the healthy development, the mortality for children under 5 years old and the main causes for death in Liuyang City from 2013 to 2020 are analyzed. Methods: The data of 725 cases of death for children under 5 years old in Liuyang City from 2013 to 2020 were collected.The causes and difference of death among the children were analyzed retrospectively by descriptive statistic methods. Results: There were a total of 144 516 live births in Liuyang City from 2013 to 2020. The mortality for children under 5 years old was 5.01‰, for infants was 3.39‰, and for newborns was 1.63‰. The male child mortality was 5.28‰, and the female child mortality rate was 4.72‰, with significant difference ( Conclusions: The mortality for children under 5 years old in Liuyang City is gradually reduced in the past 5 years. The main causes for death are premature birth and low birth weight, congenital heart disease and pneumonia. We should develop healthy education, improve the rate of prenatal diagnosis, promote the construction of obstetrics and paediatrics, and fundamentally reduce the mortality for children under 5 years old.

Abstract	Ramie (Boehmeria nivea) is noted for the production of a large biomass that has a high protein content and is rich in antioxidants. It may thus serve as a high-quality forage material to replace alfalfa and improve the meat quality of farmed animals. In this study, we evaluated the carcass characteristics and meat quality of goats when 0, 35%, 75%, and 100% of dietary alfalfa was replaced with ramie. Crude protein content (linear, P < 0.0001) and key muscle color values at 24 h after slaughter decreased with increasing ramie levels. The content of most individual amino acids, non-essential amino acids (NEAA), total amino acids (TAA), branched chain amino acids (BCAA), functional amino acids (FAA), and flavor amino acids (DAA) decreased (P < 0.05) with increasing dietary ramie. The diet in which 35% of alfalfa was replaced with ramie yielded meat with the highest amino acid content, whereas the fatty acid profile was unaffected by the inclusion of ramie. These results indicate that ramie could be used as a potential dietary forage resource for goats, and that substituting 35% of alfalfa with ramie, which is equivalent to 126 g/kg DM content, would be optimal in terms of goat meat quality.

Abstract	In this study, the complete mitochondrial genome sequence of the Liuyang black goat was investigated, and phylogenetic relationships between the Liuyang black goat and other species of Caprinae were analyzed. The total length of the mitochondrial genome was 16,715 bp, which consisted of 33.50% A, 27.27% T, 25.98% C, and 13.25% G. The mitochondrial genome contained a major non-coding control region (D-loop region), two ribosomal RNA genes, 13 protein-coding genes, and 22 transfer RNA genes. Neighbor-joining and maximum-parsimony trees of Caprinae constructed using 13 mitochondrial protein-coding genes showed that the Liuyang black goat is phylogenetically closest to Hemitragus jemlahicus (the Himalayan tahr) and Blue sheep to form clade A. Tibetan antelopes clustered separately in clade B and so did sheep in clade C.

Abstract	Objective: To investigate the risk factors for type 2 diabetes complicated with hypertension in adult residents in Liuyang, Hunan Province, P. R. China.  Methods: The residents aged at or over 18 were selected through a method of multi-stage cluster random sampling from 10 towns in Liuyang. Questionnaires, physical measurements and laboratory tests were conducted. Type 2 diabetes complicated with hypertension were served as an experimental group, while simple diabetes, non-diabetes and non-hypertension (healthy control), or non-complication and healthy group (simple hypertension, simple diabetes, and healthy group) were served as control group, respectively. Three kinds of logistic regression model were used to analyze the risk factors for type 2 diabetes complicated with hypertension.  Results: A total of 5 669 residents were included in the analysis, and the response rate was 97.74%. The results showed that the prevalence of type 2 diabetes complicated with hypertension of residents at or over 18 years old in Liuyang was 2.6% (95%CI: 2.2%, 3.1%). Logistic regression analyses demonstrated that for people at or over 60 years old, obesity and abnormal triglyceride were the independent risk factors for type 2 diabetes complicated with hypertension.  Conclusion: Aging, obesity and abnormal triglyceride can increase the risk of type 2 diabetes complicated with hypertension in adult residents in Liuyang.

Abstract	Objective: To compare loneliness, depressive symptoms and major depressive episodes between empty-nest and not-empty-nest older adults in rural areas of Liuyang city, Hunan, China. Methods: A cross-sectional multi-stage random cluster survey was conducted from November 2011 to April 2012 in Liuyang, China. A total of 839 rural older residents aged 60 or above completed the survey (response rate 97.6%). In line with the definition of empty nest, 25 participants who had no children were excluded from the study, while the remaining 814 elderly adults with at least one child were included for analysis. Loneliness and depressive symptoms in rural elderly parents were assessed using the short-form UCLA Loneliness Scale (ULS-6) and the Geriatric Depression Scale (GDS). Major depressive episodes were diagnosed using the Structured Clinical Interview for DSM-IV (SCID-I). Results: Significant differences were found between empty-nest and not-empty-nest older adults regarding loneliness (16.19±3.90 vs. 12.87±3.02, Cohen's d=0.97), depressive symptoms (8.50±6.26 vs. 6.92±5.19, Cohen's d=0.28) and the prevalence of major depressive episodes (10.1% vs. 4.6%) (all p<0.05). After controlling for demographic characteristics and physical disease, the differences in loneliness, depressive symptoms and major depressive episodes remained significant. Path analysis showed that loneliness mediated the relationship between empty-nest syndrome and depressive symptoms and major depressive episodes. Conclusion: Loneliness and depression are more severe among empty-nest than not-empty-nest rural elderly adults. Loneliness was a mediating variable between empty-nest syndrome and depression.

Abstract	Heavy metal distributions in water, sediments, and freshwater shellfish collected from Liuyang River in China have been investigated. The concentrations of heavy metals including Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Cd, and Pb were determined by ICP-MS. The distribution pattern of heavy metals in sediments was different from that in water. Large coefficients of variation of heavy metal concentrations were observed in water due to the susceptibility to discharge fluctuation and seasonal variation. Multivariate statistical analysis such as Pearson's correlation analysis, hierarchical cluster analysis (HCA), and principal component analysis (PCA) were employed to identify the possible sources of heavy metals in sediments. These heavy metals were categorized into three distinct groups, one was derived from natural existence and two were associated with anthropogenic activities. Five shellfish species including three species of gastropod mollusks (Parafossarulus eximius, Semisulcospira cancellata, and Pomacea canaliculata) and two species of bivalve mollusks (Corbicula fluminea and Anodonta woodiana) were collected and investigated. The distribution pattern of heavy metals in shellfish species was visualized by the nonmetric multidimensional scaling (NMDS) plot. The metal pollution index (MPI) values for the shellfish species were in the descending order of C. fluminea > A. woodiana > S. cancellata > P. eximius > P. canaliculata.

Abstract	Objective: To investigate the incidence and risk factors of postpartum hemorrhage in Liuyang City, Hunan Province. Methods: This was a nested case-control study. A total of 14 townships were randomly selected by cluster random sampling method from 37 townships in Liuyang City, Hunan Province. All women who got pregnant and childbirth from January 2010 to December 2011 in the above 14 townships were selected and followed up at first-trimester, second trimester, third trimester and each delivery period. Data were collected directly from maternal care manuals and the clinical records from the subjects' delivery hospitals. These whose postpartum bleeding was more than 500 mL were selected as cases, and the same amounts of normal maternal in the same cohort study whose postpartum bleeding was less than 500 mL were selected as controls. χ2 test and unconditional logistic regression analysis were applied to identify the determinants. Results: A total of 5 933 women were included in our study. The incidence of postpartum hemorrhage was 2.22%. Unconditional logistic regression analysis showed that the risk factors for postpartum hemorrhage mainly included anemia (OR=3.940, 95% CI: 2.100-7.389), scarred uterus (OR=2.730, 95% CI: 1.198-6.220), placenta previa (OR=10.665, 95% CI: 1.142-99.566), placental factors (OR=4.332, 95% CI: 1.004-18.692), and prolonged pregnancy (OR=5.899, 95% CI: 2.602-13.376). Conclusion: Postpartum hemorrhage is caused by complicated factors. Comprehensive measures should be taken to reduce postpartum hemorrhage.

Abstract	Objective: To describe the incidence and to discuss the risk factors of premature birth in rural areas of Liuyang. Methods: We collected subjects from villages and towns in Liuyang through cluster sampling method. Before enrolling in this cohort, all of them had established health records from January 2010 to December 2011. We followed up the early, middle and late stages of pregnancy until delivery, and collected medical records and maternal health care manual of this cohort as our data materials. We explored the main influence factors of premature delivery by χ2 test and unconditional logistic regression analysis for single factor and multivariate analysis. Results: Among 6270 women who enrolled in our cohort, 259 were diagnosed as premature birth. The incidence (4.13%) was lower than the national average level. Non-conditional logistic regression analysis showed that the risk factors of premature birth were as follows: OR of placental abruption was 7.678 (95% CI: 2.249-26.215), that of premature rupture of fetal membranes (PROM) was 5.177 (95% CI: 3.945-6.793), that of uterine abnormal and deformity was 2.675 (95% CI: 1.007-7.107), that of placenta anomaly was 2.633 (95% CI: 1.666-4.162), that of hypertension in pregnancy was 2.172 (95% CI: 1.044-4.521), that of pregnancy complications was 1.806 (95% CI: 1.033-3.157), that of male fetus was 1.429 (95% CI: 1.086-1.881). Protective factors of preterm birth were too frequent prenatal examination (OR=0.502, 95% CI: 1.033-3.157) and single pregnancy (OR=0.155, 95% CI: 0.075-0.319). Conclusion: Preterm delivery is caused by complicated factors, such as placental abruption, PROM and male fetus. Comprehensive measures should be taken to reduce preterm birth.

Article: The Impact of Spatial Heterogeneity on Ecosystem Service Value in a Case Study in Liuyang River Basin, China

Abstract	In previous studies the value of ecosystem services was evaluated microscopically by ecological indicators such as soil properties, biomass, carbon storage, oxygen release, water quality, and others. In this paper, the spatial heterogeneity of ecosystem services in Liuyang River basin was studied from the perspective of Geographic Information System (GIS) based spatial relationships by using a combination of geographic data and spatial analysis technologies. The Liuyang River basin was divided into grids with a resolution of 1km×1km. The weights of factors that affect the value of ecosystem services (such as topography, geological disasters, roads, scenic spots, vegetation coverage, and plant net primary productivity) were evaluated using the entropy method and analytic hierarchy process (AHP) in order to investigate the influence of natural and social factors on the value of ecosystem services in a quantitative manner. The results demonstrate that the value of ecosystem services is mainly affected by vegetation coverage, plant net primary productivity, and road network density. The value of ecosystem services grows with the increase in either vegetation coverage, plant net primary productivity, or road network density. Different types of land play different roles in ecosystem services. Cultivated land, grassland, and water each have significant supply and regulating functions while forest has significant regulating and supporting functions. The value of ecosystem services of cultivated land and water that are closely related to human activity is significantly influenced by spatial heterogeneity. In contrast, the effect of spatial heterogeneity on the value of ecosystem services of forest land and grassland that are located in mountains and hills, far away from the human accumulation zone, is insignificant.
