Survey and Research on Health Information Assistance Needs of Junior Middle School Students in Different Regions of Guangdong Province

Objective: To study the health information assistance needs of junior high school students in 8 different regions of Guangdong Province in a cluster, to understand the current situation of junior high school students' health information assistance needs, and to collect feasibility data for hospitals and schools to jointly promote the healthy development of students. Methods: In June 2019, a group of junior high school students from 8 different regions in Guangdong Province [678 students (in 2 towns), 352 students (in 2 counties and prefecture-level cities), and 1098 students (in 4 provincial-level cities)] were selected in a group. A questionnaire survey was conducted by 2128 people, the results of the questionnaire survey were collected, and statistical analysis was performed. Results: Of the 2128 junior high school students in 8 different regions, only 52.07% had confidence in their health, and there were no regional differences. Health information for students seeking professional medical assistance includes: 1578 person-times (74.15%) of nutritional diets, 1084 person-times (50.94%) to eliminate tiredness, 1190 person-times (55.92%) to improve sleep quality, 1002 person-times (47.09%) to reduce anxiety, making him happier and stronger 1164 person-times ( 54.70%). Students in different regions asked for help on how to make their hearts happier and stronger. The results suggest that provincial and county-level students have greater needs than urban students. Conclusion: The results of this research show that junior high school students in different regions of Guangdong Province have insufficient awareness of health, and there is a large demand for various health help information, and the focus is on prevention. It is of practical significance to strengthen and meet the health information needs of junior high school students

Can Clean Energy Policy Improve the Quality of Alpine Grassland Ecosystem? A Scenario Analysis to Influence the Energy Changes in the Three-River Headwater Region, China

In past decades, ecological services and functions of alpine grassland in the Three-River Headwater Region (TRHR), Qinghai-Tibetan Plateau, have been severely degraded due to overgrazing and overuse of yak dung as a fuel. Therefore, the eco-migration project has been implemented by the national government for improving eco-environmental quality in this region. This paper examines the carbon cycle change from clean energy use of households and assesses its influence on the local grassland ecosystem. Based on the data of household fuels from questionnaire surveys and local statistical yearbooks, we have calculated carbon emission and the ecological benefits by using clean energies. The results showed that total carbon in the process from Net Primary Productivity (NPP) of the ecosystem to dung fuel decreases sharply, and carbon emission from dung is approximate 6% of ecosystem NPP. Reducing the use of yak dung as a fuel has no significant influence on carbon emission, but improves the ecological benefits of the grassland ecosystem, because it is a very important part of the ecosystem carbon cycle. With the most abundant solar energy resources in China, the region should make full use of its advantage for improving ecosystem service values of alpine grassland by making more dung returns to grassland. In conclusion, a clean energy policy (CEP) can effectively improve the ecological services and functions of alpine grassland in the TRHR

Salidroside Supplementation Affects In Vitro Maturation and Preimplantation Embryonic Development by Promoting Meiotic Resumption

Salidroside (Sal) possesses several pharmacological activities, such as antiaging, and anti-inflammatory, antioxidant, anticancer activities, and proliferation-promoting activities, but the effects of Sal on oocytes have rarely been reported. In the present study, we evaluated the beneficial effects of Sal, which is mainly found in the roots of Rhodiola. Porcine cumulus oocyte complexes were cultured in IVM medium supplemented (with 250 μmol/L) with Sal or not supplemented with Sal. The maturation rate in the Sal group increased from 88.34 ± 4.32% to 94.12 ± 2.29%, and the blastocyst rate in the Sal group increased from 30.35 ± 3.20% to 52.14 ± 7.32% compared with that in the control group. The experimental groups showed significant improvements in the cumulus expansion area. Sal reduced oocyte levels of reactive oxygen species (ROS) and enhanced intracellular GSH levels. Sal supplementation enhanced the mitochondrial membrane potential (MMP), ATP level, and mtDNA copy number, which shows that Sal enhances the cytoplasmic maturation of oocytes. Oocytes in the Sal group exhibited slowed apoptosis and reduced DNA breakage. Cell cycle signals and oocyte meiosis play important roles in oocyte maturation. The mRNA expressions of the MAPK pathway and MAPK phosphorylation increased significantly in the Sal group. The mRNA expression of the oocyte meiosis gene also increased significantly. These results show that Sal enhances the nuclear maturation of oocytes. Moreover, Sal increased the number of blastocyst cells, the proliferation of blastocysts, and the expressions of pluripotency genes. Sal down-regulated apoptosis-related genes and the apoptotic cell rate of blastocysts. In summary, our results demonstrate that Sal is helpful to improving the quality of porcine oocytes in vitro, and their subsequent embryonic development

Comparative Study of Charge Trapping Type SOI-FinFET Flash Memories with Different Blocking Layer Materials

The scaled charge trapping (CT) type silicon on insulator (SOI) FinFET flash memories with different blocking layer materials of Al2O3 and SiO2 have successfully been fabricated, and their electrical characteristics including short-channel effect (SCE) immunity, threshold voltage (Vt) variability, and the memory characteristics have been comparatively investigated. It was experimentally found that the better SCE immunity and a larger memory window are obtained by introducing a high-k Al2O3 blocking layer instead of a SiO2 blocking layer. It was also confirmed that the variability of Vt before and after one program/erase (P/E) cycle is almost independent of the blocking layer materials
