Sufeng Liao, Jianghong Liu, Ming Xu, Jingui Zheng
Advances in Bioscience and Biotechnology (ABB) , 2018, DOI: 10.4236/abb.2018.99030
Abstract: This study aims to evaluate the preventive effects of anthocyanins extracts (MAEs) from mulberry variety PR-01 against N-nitrosodiethylamine (NDEA)-induced hepatocarcinogenesis in rats. It was found that 150 mg·kg-1 MAEs treatment significantly reduced the NDEA-induced hepatic nodules incidence and hepatocellular carcinoma incidence by 58.30% and 41.70% compared to the model group. Meanwhile, MAEs significantly restored the elevated the liver function enzymes, inhibited the tumor necrosis factor alpha and interleukin-6 levels, elevated the serum interleukin-10 and interferon-γ and increased hepatic glutathione-S-transferase and UDP-glucuronosyltransferase 2B1 enzyme activity. Moreover, 150 mg·kg-1 MAEs supplement enhanced glutathione content and the activities of superoxide dismutase, catalase, glutathione peroxidase activities but reduced the malondialdehyde and thiobarbituric acid-reactive substances content by 37.90% and 44.52%. Furthermore, MAEs pretreatment maintained nuclear factor erythroid 2-related factor 2 (Nrf2), Kelch-like ECH-associated protein 1, heme oxygenase-1, and NAD(P)H: quinine oxidoreductase1 stimulation and inhibited the expression of TNF-α, nuclear factor-kappaB (NF-κB), and cyclooxygenase-2 (COX-2), indicating that MAEs exhibit effectively prevention effects against liver cancer via decreased lipid peroxidation, induced Nrf2-mediated antioxidant enzymes and attenuating the inflammatory mediators COX-2 through NF-κB pathway. Thus, MAEs of mulberry variety
Breastfeeding and Active Bonding Protects against Children’s Internalizing Behavior Problems
Jianghong Liu,Patrick Leung,Amy Yang
Nutrients , 2014, DOI: 10.3390/nu6010076
Abstract: Breastfeeding is associated with numerous health benefits to offspring and mothers and may improve maternal-infant bonding. Ample evidence suggests breastfeeding can improve child neurodevelopment, but more research is needed to establish whether breastfeeding is linked to the development of child psychopathology. This paper aims to explore the effects of both breastfeeding and mother-child interactions on child behavioral outcomes at a later age. Children from the China Jintan Child Cohort Study ( N = 1267), at age six years old were assessed, along with their parents. Children who were breastfed exclusively for a period of time in the presence of active bonding were compared to those who were breastfed in the absence of active bonding as well as to children who were not exclusively breastfed, with or without active bonding. Results from ANOVA and GLM, using SPSS20, indicate that children who were breastfed and whose mothers actively engaged with them displayed the lowest risk of internalizing problems (mean = 10.01, SD = 7.21), while those who were neither exclusively breastfed nor exposed to active bonding had the least protection against later internalizing problems (mean = 12.79, SD = 8.14). The effect of breastfeeding on internalizing pathology likely represents a biosocial and holistic effect of physiological, and nutritive, and maternal-infant bonding benefits.

TELKOMNIKA : Indonesian Journal of Electrical Engineering , 2012, DOI: 10.11591/telkomnika.v10i7.1602
Abstract: The local dimming backlight technique enables liquid crystal display to present images with high contrast ratio and low power consumption. Considering that it is more important to make sure a high quality of the displayed image when reducing the power consumption, therefore, in this paper the new algorithm chooses RPSNR (the peak signal-to-noise ratio) =30 as the lowest standard to guarantee the quality of image. RPSNR =30 could provide a value that the maximum distortion of the image can be accepted, then, we substitute the maximum gray level of each region into the formula to judge whether satisfy the flow chart. If the value do not meet the condition, we decrease it one by one until find the right value. Finally, we take the luminance of the right value as backlight luminance. Meanwhile, a method is also proposed in this paper to simplify the calculation time. Successive searches will be made on the basis of the n (ranging from 0.1 to 1) times of the maximum luminance, and stop when RPSNR>=30. However, in order to guarantee the quality of the image, the 0.7 times of the maximum luminance is used as the minimum backlight luminance. In the end, we only choose 0.7, 0.8 and 0.9 times of the maximum luminance as backlight luminance.

PLOS ONE , 2013, DOI: 10.1371/journal.pone.0065230
Abstract: Objectives Examine the relationships between blood lead concentrations and children's intelligence quotient (IQ) and school performance. Participants and Methods Participants were 1341 children (738 boys and 603 girls) from Jintan, China. Blood lead concentrations were measured when children were 3–5 years old. IQ was assessed using the Chinese version and norms of the Wechsler Preschool and Primary Scale of Intelligence – Revised when children were 6 years old. School performance was assessed by standardized city tests on 3 major subjects (Chinese, Math, and English [as a foreign language]) when children were age 8–10 years. Results Mean blood lead concentration was 6.43 μg/dL (SD = 2.64). For blood lead concentrations, 7.8% of children (n = 105) had ≥10.0 μg/dL, 13.8% (n = 185) had 8.0 to <10.0 μg/dL, and 78.4% (n = 1051) had <8.0 μg/dL. Compared to children with blood lead concentrations <8 μg/dL, those with blood lead concentrations ≥8 μg/dL scored 2–3 points lower in IQ and 5–6 points lower in school tests. There were no significant differences in IQ or school tests between children with blood lead concentrations groups 8–10 and ≥10 μg/dL. After adjustment for child and family characteristics and IQ, blood lead concentrations ≥10 μg/dL vs <8 μg/dL at ages 3–5 years was associated with reduced scores on school tests at age 8–10 years (Chinese, β = ?3.54, 95%CI = ?6.46, ?0.63; Math, β = ?4.63, 95%CI = ?7.86, ?1.40; English, β = ?4.66, 95%CI = ?8.09, ?1.23). IQ partially mediated the relationship between elevated blood lead concentrations and later school performance. Conclusions Findings support that blood lead concentrations in early childhood, even <10 μg/dL, have a long-term negative impact on cognitive development. The association between blood lead concentrations 8–10 μg/dL and cognitive development needs further study in Chinese children and children from other developing countries.

Chinese Science Bulletin , 2005, DOI: 10.1007/BF02899651
Abstract: Water mist is one of the effective candidates for halon replacement used in electrical environment fire protection. Water mist additives may greatly enhance fire suppression effectiveness. In electrical environment, electrical breakdown field strength (E) is one of the important factors that control the performance of electrical equipment. In this study the variation principles of electrical breakdown field strength and the electrical characteristics of MC additives were investigated by electrode discharging experiments. Experimental results showed that electrical breakdown field strength was impacted obviously by the conductive metal ions and insulated fluorocarbon surfactants in MC additives. The attenuation percentages ofE in different experimental cases were described, thus providing scientific guidance for the use of water mist and MC additives in electrical fire suppression.

寒旱区科学 , 2011,
Abstract: This paper uses Landsat TM images, GIS technology, Digital Elevation and Habitat Assessment Models to assess the habitat suitability of the endangered plant Tetraena mongolica in western Ordos Plateau of China by selecting terrain, soil, climate, and human activity factors as assessment indices. The results are as follows: natural factors such as climate and terrain are not restrictive factors for the survival and development of T. mongolica in the research region, whereas human activity causes habitat quality of T. mongolica to change intensively in quantity and distribution. The area of less suitable habitat increased by 23.87 km2 compared to potential habitat suitability. Thus, in some areas, human activity may be a key factor causing the endangerment of T. mongolica. There were obvious differences of potential and practical habitat suitability between different habitat regions in the study area. The habitat quality was better in Wujiamiao, Dishan and Qipanjing regions, and worse in Wuda and Qianlishan regions.

Journal of Politics and Law , 2009, DOI: 10.5539/jpl.v1n4p57
Abstract: A tide of party foundation and activity appears in early Republic of China. During this period, party politics differs from that in western capitalism countries in its growth and decline, which is derived from China’s special economic and political features after the 1911 revolution. By studying the growth and decline history of parties in early Republic of China, we find that: the fundamental problem of party politics in early Republic of China is that parties can not satisfy the requirements of modern political civilization.
Microstructure and mechanical properties of titanium nitride coatings for cemented carbide cutting tools by pulsed high energy density plasma
Zhijian Peng,Hezhuo Miao,Longhao Qi,Jianghong Gong,Size Yang,Chizi Liu
Chinese Science Bulletin , 2003, DOI: 10.1007/BF03184169
Abstract: Hard, wear-resistant and well-adhesive titanium nitride coatings on cemented carbide cutting tools were prepared by the pulsed high energy density plasma technique at ambient temperature. The results of Auger spectra analysis indicated that the interface between the coating and substrate was more than 250 nm. Under optimized deposition conditions, the highest critical load measured by nanoscratch tester was more than 90 mN, which meant that the TiN film was well adhesive to the substrate; the highest nanohardness and Young’s modulus according to nanoindentation tests were near to 27 and 450 GPa. The results of cutting tests evaluated by turning hardened CrWMn steel in industrial conditions indicated that the wear resistance and edge life of the cemented carbide tools were enhanced dramatically because of the deposition of titanium nitride coatings. These improvements were attributed to the three combined effects: the deposition and ion implantation of the pulsed plasma and the becoming finer of the grain sizes.
