ABSTRACT
Military vocational education has become one of the strategies to strengthen the military in the new era. The army urgently needs to build a number of featured online courses of military vocational education. Therefore, taking the course "Knowledge and Skills of Health Education for the Army" as an example, this paper discusses the overall construction objectives, construction ideas, teaching content, curriculum and test question bank construction of the course. In addition, this paper analyzes and summarizes the problems existing in the teaching organization, implementation, and preliminary application, so as to provide ideas and construction strategies for the construction of online open courses in other military vocational education.
ABSTRACT
Objective@#To explore the blood lead level and its relationship with behavior in school-age children from rural areas of Chongqing.@*Methods@#A total of 697 students from grades 3 to 6 in the fall semester of 2014 from 14 rural townships in one district of Chongqing was selected by using the random cluster sampling method. Blood were sampled to analyze the lead level. Neurobehavioral tests were performed to determine their personal cognitive and memory ability. Questionnaires and physical examinations were administered to obtain the information of confounding factors. All students were divided into Q1-Q4 groups according to the quartile of their blood lead level. The relationship between the blood lead level and behavior was analyzed by multivariate logistic regression model and restricted spline regression model.@*Results@#The mean age of 697 students was (10.07±1.36) years old, and the median (interquartile range) of their blood lead level was 44.31 (35.42) μg/L. Multivariate logistic regression model showed that after adjusting for age, gender, body mass index and maternal culture level, compared with Q1 group, the OR (95%CI) values of high digit symbol substitution test (DSST) scores and high overall memory quotient (MQ) scores in Q3 group were 1.65 (1.01-2.70) and 2.10 (1.21-3.62), and the OR (95%CI) value of high long term memory (LTM) scores in Q4 group was 0.53 (0.31-0.92). The results of the restricted spline regression model showed that the dose-response curves between the blood lead level and MQ/LTM test scores were both parabolic (P<0.05).@*Conclusion@#The blood lead level of school-age children from rural areas of Chongqing is the same as that from other areas of China, but slightly higher than that from other areas of Chongqing. Children with higher blood lead level have poor long-term memory ability.
ABSTRACT
Based on participatory idea, we constructed a novelty model of participatory health edu-cation, which was based on participatory research as the module, participatory role-playing as the core mod-ule, participatory review as enhanced module (abbreviation to as "3-PR"). We applied it to pre-selected health officer health promotion activities, and randomized controlled trials were designed. The results showed that "3-PR" model of participatory health education might be more effective in promoting health literacy than conventional health education methods. "3-PR" health education model has the advantages of participation, practicality, fun and flexibility, integration and education, which has certain reference signifi-cance for exploring health education methods and improving the health of the whole people.
ABSTRACT
Objective To investigate risk factors for healthcare-associated infection(HAI)in patients with craniocerebral operation,and provide reference for the prevention and control of HAI.Methods A total of 4 246 cases of craniocerebral surgery in a neurosurgery department from January 2010 to December 2012 were enrolled in the study,the risk fac-tors for HAI were analyzed.Results Of 4 246 cases of craniocerebral surgery,393 patients developed 446 times of post-operative HAI,HAI incidence rate was 9.26%,case infection rate was 10.50%,which were higher than inci-dence (2.02%)and case infection rate (3.02%)of HAI of all hospital during the same period,the difference was statistically significant (χ2 =811 .06,629.30,respectively,P 7 d,antimicrobial use >7 d,central venous and urinary tract cathe-terization,invasive ventilator were risk factors for HAI in patients with craniocerebral operation.Conclusion The incidence of HAI in patients with craniocerebral operation is high,effective preventive and control measures accord-ing to risk factors should be strengthened to reduce the incidence of HAI.
