RESUMO
Objective:To explore the potential categories and influencing factors of online learning behavior in Junior college nursing students in post epidemic era.Methods:A total of 978 nursing students from Heilongjiang Nursing College in December 2021 were investigated by the general information questionnaire, Online Learning Behavior Scale, Online Learning Self-Efficacy Scale, Proactive Personality Scale and Online Learning Attitude Scale. The latent profile analysis and ordered multi-classification Logistic regression analyses were applied to identify the factors associated with the potential categories of online learning behavior.Results:The online learning behavior of nursing students were divided into 3 categories: outstanding(12.68%, 124/978), good(75.66%,740/978)and mediocrity(11.66%, 114/978). Gender, online learning self-efficacy, proactive personality and online learning attitude were predictors that influence the classification of potential profiles of online learning behavior in nursing students( P<0.05). Conclusions:There are 3 potential categories of online learning behavior in nursing students, and nursing educators should pay attention to the characteristics of online learning behaviors of different nursing students and take various effective measures to improve online learning behaviors of nursing students.
RESUMO
Objective:To evaluate the effect of health education of a three-year special action for prevention and control of drinking water-borne endemic fluorosis (referred to as drinking water-borne fluorosis) in Shandong Province, and to provide basis for formulating health education measures in the next step.Methods:Nineteen of the disease affected counties (cities and districts) were selected as project counties (cities and districts) in key areas for prevention and control of drinking water-borne fluorosis in Shandong Province in 2018, and 50 disease affected counties (cities and districts) were selected in 2019, and the project counties (cities and districts) were expanded to all of the 105 disease affected counties (cities and districts) in Shandong Province in 2020. Three disease affected townships (towns) were selected in each county (city and district), and health education activities on drinking water-borne fluorosis were carried out in Grade 4 to Grade 6 of the central primary schools and the three villages under its jurisdiction. Students and housewives were selected to conduct questionnaire surveys on prevention and control knowledge of drinking water-borne fluorosis before and after health education. The incidence of dental fluorosis among children aged 8 - 12 years was investigated annually in 6 villages (with children aged 8 - 12 years > 50) , where health education activity was implemented and the incidence of dental fluorosis among children was > 30%, water fluoride content was > 1.5 mg/L and water improvement time was < 5 years.Results:After health education, the awareness rates of drinking water-borne fluorosis in fifth grade pupils [92.46% (4 571/4 944) vs 65.80% (3 334/5 067) in 2018; 94.84% (12 897/13 599) vs 73.55% (9 993/13 587) in 2019; 95.59% (30 407/ 31 809) vs 77.52% (24 463/31 557) in 2020] and housewives [94.12% (2 400/2 550) vs 76.04% (1 939/2 550) in 2018; 94.99% (6 412/6 750) vs 72.00% (4 860/6 750) in 2019; 95.53% (16 183/16 941) vs 78.43% (12 971/16 539) in 2020] were significantly improved (χ 2 = 1 070.47, 2 315.27, 4 456.40, 328.25, 1 294.80, 2 174.63, P < 0.05). After health education in 2020, there were significant differences in the correct answer rates of epidemic causes, hazards and preventive measures of drinking water-borne fluorosis in the questionnaire of fifth grade pupils and housewives (χ 2 = 390.78, 164.94, P < 0.05). The awareness rates of drinking water-borne fluorosis in fifth grade pupils and housewives in the eastern region (Qingdao City, Yantai City and Weifang City) were significantly higher than those in the western region (Dezhou City, Liaocheng City and Heze City) before health education (χ 2 = 547.43, 210.12, P < 0.05), and after health education, the awareness rates increased to more than 90%. The detection rate of dental fluorosis in children decreased year by year (χ 2trend = 27.95, P < 0.05). Conclusions:Through implementation of a three-year special action for prevention and control of drinking water-borne fluorosis in Shandong Province, the awareness rate of fluorosis among target populations has been significantly improved. However, it is still necessary for government departments to further increase investment in health education and carry out health education activities in a deep-going way.
RESUMO
Objective To establish the reference intervals (RIs) of the four biochemical parameters for liver function [aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transpeptidase (GGT), and alkaline phosphatase (ALP)] in adults by using the indirect method based on the data of subjects undergoing physical examination in laboratory information system (LIS). Methods With the help of the LIS, related data were collected from the healthy adults who underwent physical examination in Physical Examination Center of The First Hospital of Jilin University from October 2019 to October 2020. The Kolmogorov-Smirnov test was used to check the normal distribution of the original data; data with skewed distribution were transformed into data with approximate normal distribution using the BOX-COX method; the Turkey method was used to remove outliers; the Mann-Whitney U test or the Z -test was used for comparison between groups; the non-parametric method was used to calculate RIs. Results A total of 27 218 subjects were included after the removal of outliers. All four parameters showed age and sex differences. The RIs of AST were 14-39 U/L for male individuals aged 20-79 years, 12-32 U/L for female individuals aged 20-49 years, and 14-39 U/L for female individuals aged 50-79 years; the RIs of ALT were 10-71 U/L for male individuals aged 20-54 years, 10-49 U/L for male individuals aged 55-79 years, 7-43 U/L for female individuals aged 20-49 years, and 9-49 U/L for female individuals aged 50-79 years; the RIs of GGT were 11-70 U/L for male individuals aged 20-64 years, 10-64 U/L for male individuals aged 65-79 years, 6-45 U/L for female individuals aged 20-49 years, and 7-54 U/L for female individuals aged 50-79 years; the RIs of ALP were 38-96 U/L for male individuals aged 20-79 years, 33-89 U/L for female individuals aged 20-49 years, and 40-106 U/L for female individuals aged 50-79 years. The RIs of AST, ALT, and GGT established in this study were similar to those in the industry standards of China (relative deviation < reference change value), and the RIs of all four biochemical parameters were verified by applicability. Conclusion The RIs of the four biochemical parameters for liver function established by the indirect method are relatively consistent with those established by the direct method, which holds promise for application in clinical laboratory.
RESUMO
Objective To compare influences of enteral nutrition (EN) and parenteral nutrition (PN) on the inflammatory factors and immune functions in patients with systemic inflammatory response syndrome. Methods Totally 85 patients who were treated in the First Hospital of Shanxi Medical University, Shanxi Province People's Hospital, and Taiyuan Central Hospital from April, 2006 to April, 2010 were enrolled in this study and divided into EN group (n = 49) and PN group (n = 36) according to nutrition support modes. The changes of inflammatory factors and immune functions after nutritional supports were recorded and compared between these two groups. Results The weight, arm circumference, skin fold thickness of brachial triceps, total protein, and serum albumin were significantly improved on the 7th and 14th day after nutrition supports in both two groups compared with the baseline levels (all P ＜ 0.05). On the 14th day after nutritional support, the levels of total protein and serum albumin were significantly higher in EN group than in PN group. On the 7th and 14th day, the levels of tumor necrosis factor-α, Interleukin (IL)-8, and IL-1β in EN group were significantly lower than those in PN group and baseline levels (all P ＜ 0. 05). The blood CD4/CD8 and IgG in EN group were significantly increased compared with the baseline levels and those in PN group (both P ＜0. 05). Conclusions Both PN and EN can effectively improve the nutritional status of patients with SIRS. EN has superior effectiveness in EN group than in PN group in terms of improving nutritional status, ameliorating immune function, and reducing the release of inflammatory factors.
