文摘Introduction: Due to its health, social and economic morbidity, dental caries leads to absenteeism and a drop in school performance among schoolchildren. The objective of this work is to study dental caries and its determinants in pupils known as Children of Troop (CT) of the “Military School of Saint Louis” (MSS). Method: This was a descriptive and cross-sectional study. Recruitment was exhaustive. The collection was made at the school and has covered the period of March 10 throughout June 13, 2014 in an individual interview, based upon a deliberate consent, using a questionnaire drawn up on the basis of the variables studied. The bivariate analysis was done with the Epi Info software version 3.5.3. Results: The mean age of CT was 14.9. The prevalence of caries was 61.2%. Determinants related to caries were: sugar intake between meals (OR = 6.44 [3.4 - 11.9]);insufficient tooth brushing (OR = 14.3 [8.8 - 23.29]);(OR = 3.84 [2.38 - 7.14]) and for regular dental visits (OR = 5.26 [3.44 - 8.33]), with the last dental visit dating back more than one year. Conclusion: In the face of challenges of school performance of CT, it is necessary to set up a control plan focusing mainly on the factors identified and associated with dental caries in military school.

文摘Background:High altitude shock is attributed to myocardial ischemia and hypoxia.Jiuwei Shengmai powder has positive impacts on human physiology.However,it is unknown if it can mitigate myocardial ischemia and hypoxia.This study aimed to postulate the molecular mechanism that relieves myocardial hypoxia injury in officers and soldiers at high altitude after ingesting Jiuwei Shengmai powder by using network pharmacology and molecular docking.Methods:The effective components and potential targets of Jiuwei Shengmai powder were detected by databases such as the traditional Chinese medicine systems pharmacology(TCMSP),PubChem,and UniProt.Target genes related to myocardial hypoxia injury were identified using Gene Cards,Online Mendelian Inheritance in Man,DrugBank,DisGeNET,the Comparative Toxicogenomics Database,and other databases.CytoScape was used to construct a“drug-active ingredient-target gene”network.Protein-protein interactions(PPIs)were predicted using the STRING database.Core gene target data were analyzed using Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment utilizing R packages,while Autodock Vina was used to verify the molecular docking simulation.Results:One hundred and sixteen active ingredients were identified in Jiuwei Shengmai powder and were shown to target 197 genes.Of these,3073 core target genes were related to myocardial hypoxia injury,and 130 core genes were obtained after Veen intersection.There were 129 PPI nodes and 1769 edges.The docking binding energy was≤-5.0 kcal·mol-1,indicating strong binding between the active compounds and targets.Quercetin and kaempferol are the main components in Jiuwei Shengmai powder that relieve myocardial hypoxia injury.Their core targets are interleukin-6 and activated cysteine proteinase-3 antibody,which are mainly related to PI3K-Akt-,mitogen-activated protein kinase(MAPK),tumor necrosis factor(TNF),and interleukin 17(IL-17)signaling pathways.
文摘Wu Zhudi and Qin Guifang,two girls among the elite few chosen from thousands of candidates as female pilots,traveled in a cramped troop train.Cheerful and spirited,they shared Laughter and conversation along the way.Among the girls traveling north from Hankou,seven became New China’s first female pilots.Interestingly,three of the seven girls came from Guangdong Province(Wu Zhudi,Oin Guifang,and Wang Jian),three from Hunan(Wan WanLing,Zhou Zhenming,and Zhou Yingzhi),and one from Henan(Wu Xiumei).
文摘On June 14,the U.S.staged its first large-scale military parade since the conclusion of the Gulf War in 1991.The grand event,which lasted more than two hours,featured over 6,000 active-duty service members,128 tanks,armored vehicles,and artillery systems,along with 62 military aircraft.In recent years,America's global strategy has largely been in retreat一whether through its hasty withdrawal from Afghanistan or the restraint shown in the Red Sea amid attacks by Yemen's Houthi forces.Against this backdrop,the Donald Trump administration's insistence on holding the parade can be seen as an effort to restore a sense of national pride,boost troop morale and public confidence,and send a strong deterrent message to potential adversaries.
