Abstract With the increase of total energy consumption, eco-environmental quality drops sharply, which has attracted concerns from all circles. It has become the top priority of construction of socialist ecological civilization to clarify the influences of energy consumption on the level of eco-environmental pollution. Ecological environmental pollution control cannot be one size fits all. It can avoid resource depletion and environmental deterioration via adjusting measures to local conditions to coordinate ecological environmental pollution and energy consumption problems. In this essay, entropy method is adopted to measure the composite indexes of eco-environmental pollution of 30 provinces and cities in China, based on… More >

Abstract Soil moisture is an important indicator for agricultural planting and agricultural water management. People have been trying to guide crop cultivation, formulate irrigation systems, and develop intelligent agriculture by knowing exactly what the soil moisture is in real time. This paper considers the impact of meteorological parameters on soil-moisture change and proposes a soil-moisture prediction method based on the Gene Expression Programming (GEP) algorithm. The prediction model is tested on datasets from Shunyi, Yanqing and Daxing agricultural farms, Beijing. The results show that the GEP model can predict soil moisture with a maximum correlation coefficient of 0.98, and the root-mean-square… More >

Abstract Objective: To investigate the prevalence of emotional and behavioral problems and related factors of left-behind children in impoverished rural China (mainly in the first grade of junior high school). Methods: A cross-sectional survey of rural households in 27 poverty-stricken counties in 12 provinces across China was conducted using the Strengths and Difficulties Questionnaire (SDQ). Results: The prevalence of emotional and behavioral problems in left-behind children was 11.7%, and that of non-left-behind children was 8.9%. There was statistical difference between the two groups (P < 0.01). There are no differences between the two groups in terms of the various factors of… More >

Abstract When COVID-19 pandemic hit China, Chinese clinical psychologists, counselors and other practitioners reacted quickly to provide psychological interventions for different target groups. Different professional ethical concerns and potential transgressions arose during different stages of pandemic. This paper aimed to summarize different ethical concerns and transgressions during different stages of pandemic in China, as well as how the professional ethical workgroup in the registration system of clinical psychologists and professional organizations of Chinese Psychological Society (CPS) to publish a series of documents as recommendations on ethical practice. It is hoped by providing a picture of “problems vs. solutions” in terms of… More >

Abstract To understand the anthocyanin characteristics of wine grape varieties, the anthocyanin composition and content of 31 wine grape varieties were analyzed to explore the use of anthocyanins as chemical fingerprints to distinguish varieties. Results showed that a total of 21 anthocyanins were detected in the skins, including cyanidin, delphinidin, petunidin, peonidin and malvidin 3-monoglucosides (or 3,5-diglucosides) along with the corresponding acetyl and p-coumaroyl derivatives. The highest and lowest total amount of anthocyanins were detected in ‘Ruby Cabernet’ and ‘Muscat Rouge’, respectively. In the 21 Vitis vinifera grapes, there were 3~11 monoglucoside anthocyanins detected, however, there were 4 to 9 monoglucoside… More >

Abstract The humification degree of fresh litter directly controls the accumulation of soil humus derived from plant litter, but very little information on this process is available. Planted forests are well known to restrict soil fertility, which is often indicated by the soil humus level. In this study, fresh litter was collected during different plant phenological stages during 2016 and 2017 in a mixed plantation in Southwest China. The values of hue coefficient ΔlogK (absorbance ratio of 400 nm and 600 nm on a logarithmic scale), optical density E4/E6 (absorbance ratio of 400 nm and 600 nm) and A600/C (absorbance at… More >

Abstract The epidemic outbreak COVID-19 was first detected in the Wuhan city of China and then spread worldwide. It is of great interest to the researchers for its high rate of infection spread and its significant number of fatalities. A detailed scientific analysis of this phenomenon is yet to come. However, it is of interest of governments and other responsible institutions to have the right facts and figures to take every possible necessary action such as an arrangement of the appropriate quarantine activities, estimation of the required number of places in hospitals, assessment of the level of personal protection, and calculating… More >

Abstract The impact of greenization on the marginal utility of the intensity of carbon emissions in China and factors influencing this relationship are explored in this study. China’s level of greenization is evaluated by using an index system developed based on the comprehensive index method. The intensity of carbon emissions is determined by using the standards for the coefficients of conversion of coal equivalent and coefficients of carbon emission. The impact of greenization on the marginal utility of the intensity of carbon emissions is then evaluated by using an elastic formula and factors affecting this relationship are verified by regression analysis.… More >

Abstract Background: Previous studies from high altitudes have reported significantly higher prevalence of congenital heart disease (CHD), consisting almost solely of simple CHD. Little is known about the occurrence of complex CHD. Neonates with complex CHD are likely admitted to NICU. We examined the prevalence and spectrum of complex CHD in NICU in order to depict a truer picture of CHD at high altitude. Methods: We reviewed charts of 4,214 neonates admitted to NICU in Qinghai province (average altitude 3,000 m). Echocardiography was performed in 1,943 babies when CHD was suspected based on clinical examinations. Results: CHD was diagnosed in 1,093… More >

Abstract Background: There is scarce research on large cohorts with tetralogy of Fallot (TOF) from China. The database in Fuwai Hospital was reviewed to ascertain current trends in the management of TOF and to determine the prevalence of various surgical techniques and the optimal early outcome. Methods: This cross-sectional study included 1861 patients who underwent surgery between 2012 and 2017 and were aged 0-18 years old with a primary diagnosis of TOF. A total of 1760 eligible patients were included in the analyses. Results: A total of 1683 patients underwent repair of TOF as a one-stage operation (primary repair). Sixty-one patients… More >
