Objective To study the earthquake emergency response capability and post-earthquake psychological state of students after the Wenchuan earthquake. And also, to investigate the level of earthquake-related knowledge so as to provide basic information for enhancing the emergency response capabilities among college students. Methods We selected 1% Sichuan University students by convenience sample method and conducted the survey in person with a self-designed questionnaire. Results were analyzed with Epidata 3.0 and SPSS13.0 software. Results We distributed 527 questionnaires and 517 (97.27%) valid questionnaires were retrieved. Most college students had a good grasp of earthquake knowledge: 65.4% to 97.7% of the responders gave the correct answers, but only 12.77% said they had ever received earthquake survival training. 15.2% suffered from fear after the earthquake, 59.4% became uneasy, and 25.4% remained calm. Gender, grade, or major were not the factors influencing the psychological state of college students after the earthquake (P= 0.246, 0.216, and 0.406, respectively). Also, earthquake survival training did not influence the psychological state of college students after the earthquake (P=0.090). Psychological intervention after the earthquake was identified as an important factor that affected the psychological state of students (P=0.002). Conclusion College students have a good grasp of the basic knowledge regarding earthquake, but relevant survival training is far from sufficient. Universities should strengthen earthquake survival training, enhance the post-earthquake emergency response capacity of students, and carry out post-disaster psychological intervention directly following an earthquake. There is no significant difference in the mental status among students of different genders, grades, or professional backgrounds.
ObjectiveTo discuss the application of Miller pyramid teaching method in the competency training of new nurses in hemodialysis room and evaluate the effect.MethodsFourteen new nurses in hemodialysis room adopting conventional teaching method from January 2017 to December 2018 were retrospectively selected as the control group; from January to December 2019, another 14 new nurses in hemodialysis room were prospectively selected as the trial group and Miller pyramid teaching method was adopted. After three months of training, the theory and operation of the two groups of new nurses were assessed, and the post competency was assessed by using the Competency Inventory for Registered Nurse, and the teaching satisfaction was assessed by using the self-designed questionnaire on the teaching effect satisfaction of new nurses in hemodialysis room. The data of the two groups were compared.ResultsThe theoretical examination score (91.54±5.89 vs. 83.86±6.45), operational examination score (96.89±3.65 vs. 90.58±5.15), score of Competency Inventory for Registered Nurse (186.66±4.89 vs. 163.76±6.89), and teaching satisfaction (4.56±0.72 vs. 3.56±0.97) in the trial group were all higher than those in the control group, the differences were statistically significant (P<0.05).ConclusionMiller pyramid teaching method is feasible to train the post competency of new nurses in hemodialysis room, which is helpful to improve the theoretical basis, operational skills, post competency, and teaching satisfaction of new nurses in hemodialysis room.
Objective To compare the effect of high-frequency chest wall oscillation (HFCWO) expectoration and mechanical vibration (MV) expectoration in elderly patients with pulmonary infection. Methods Thirty elderly patients with pulmonary infection were randomly divided into a HFCWO group and a MV group with 15 patients in each group. On the basis of routine treatment, the HFCWO group was treated with HFCWO vest to help expectoration, and the MV group underwent traditional mechanical vibration to help expectoration. The respiratory rate, peripheral oxygen saturation (SpO2), activities of daily living (ADL) score were measured before treatment (D1), 7 days (D7), and 14 days (D14) after treatment. Results Except ADL score had no difference between D7 and D14 in the MV group, there were significant differences in daily amount of sputum, respiratory rate, SpO2, ADL score between D1, D7, and D14 in both groups (P<0.05). There were no significant differences in daily amount of sputum between two groups on D1, D7, or D14. SpO2 and ADL score were significantly higher in the HFCWO group on D7 and D14 compared with the MV group (P<0.05). Conclusions Both high-frequency chest wall oscillation and mechanical vibration are effective in improving expectoration. The HFCWO vest is superior in improving blood oxygen and relieving shortness of breath than mechanical vibration expectoration.
Due to the decline of motor ability and the impact of the diseases, abnormalities in gait is common in the elderly population, which will raise the risk of fall and cause serious injury. This study focuses on the analysis of the gait kinematics parameters of normal adults’ gait, aiming to investigate the characteristics of gait parameters in different age groups and to explore the role of gait parameters in motor function assessment and clinical diagnosis. Based on the gait data gained by electronic walkway, the relationship among the toe out angles and their correlation with age and gender etc. were quantitatively analyzed. The results show that most normal subjects walk with positive toe out angles, and the angles increase with age. Such changes are slow in the young and middle age groups. However, the elevations of the left out toe angle and the angles between the feet are statistically significant after entering elder age ( >60 years). The results also suggest that the angle between the feet is a kind of practical gait parameter for varying applications. This study concludes that feet angle analysis is potential to provide a convenient and quantitative tool for the assessment of lower limb motor ability and the diagnosis of knee joint diseases.
Objective To study the responsiveness change of neutrophils when experiencing the second insult after the initial temperature activation in cardiopulmonary bypass (CPB) by using an in vitro model. Methods The neutrophils were isolated from blood which was drawn from each of 60 health volunteers. The samples were divided into 5 groups including normothermia, tepid temperature, moderate hypothermia, deep hypothermia, and rewarming hyperthermia by random digital table with 12 in each group according to the change of temperature during CPB. An in vitro model for studying neutrophil responsiveness was established by using a polymerase chain reaction thermocycler. Five time points were set for each group, including T0: starting CPB, T1: starting rewarming, T2: 0.5 h after rewarming, T3: 1 h after rewarming, and T4: 1.5 h after rewarming. Platelet activating factor (PAF) was added into each group at T2, T3, and T4, and then the value of membranebound elastase (MBE) activity was measured as responsiveness of neutrophils. Analysis of covariance was applied by using SPSS 13.0 for statistic analysis. If the [CM(159mm]covariance had significant difference between main effects, Bonferroni method would be applied for pairwise comparison. Results The main effect difference of neutrophil responsiveness among different groups was statistically different (F=4.372,P=0.002). MBE value had no statistical difference between the normothermia and tepid temperature groups (81.9±4.5 ng/10.6 cells vs. 76.5±3.6 ng/106 cells, P=0.134). while the MBE values in these two groups were higher than those in the other three groups (P=0.001). MBE value in the rewarming hyperthermia group was higher than that in the deep hypothermia group (61.2±2.7 ng/106 cells vs. 50.9±3.7 ng/106 cells, P=0.005). There was no statistical difference between the moderate hypothermia group (56.4±3.2 ng/106 cells) and the rewarming hyperthermia group (P=0.167), so was it between the moderate hypothermia group and the deep hypothermia group (P=0.107). The main effects of neutrophil responsiveness at different time points was statistically different (F=3.566, P=0.03) when PAF was added. MBE value at T4 was higher thanthat at T2 (70.9±2.5 ng/106 cells vs. 59.9±2.3 ng/106 cells, P=0.027). There was no statistical difference among T3 (65.5±1.8 ng/106 cells), T2 (P=0.168), and T4 (P=0.292) in MBE value. Conclusion Normothermia， tepid temperature， and rewarming hyperthermia during CPB can enhance neutrophil responsiveness and MBE release when neutrophils suffer the second insult. There is a time window for neutrophils to be easily activated during rewarming period.
