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.
ObjectiveTo investigate the effects of health education pathway intervention on self-care agency and health lifestyle promotion in colostomy patients. MethodsEighty-eight rectal cancer patients who had undergone colostomy were randomly divided into control group and intervention group (with 44 patients in each) between March 2012 and September 2013. The control group received conventional nursing only, while the intervention group were given health education pathway intervention besides conventional nursing. The self-care agency and health lifestyle promotion in the two groups under pre-colostomy state, one week after colostomy and two weeks after colostomy were surveyed and compared based on the exercise of self-care agency scale and the health promotion lifestyle profile. ResultsAfter health education pathway intervention, the scores of self-care agency and health lifestyle promotion in the intervention group were significantly higher than those in the control group (P<0.05), and the hospitalization expenditure was also obviously lower. Furthermore, the satisfaction degree on nursing service was significantly higher than that of the control group (P<0.05). ConclusionThe health education pathway intervention can greatly improve self-care agency and quality of life in rectal cancer patients who have undergone colostomy.

Objective To evaluate the effects of enhanced external counterpulsation (EECP) on exercise capacity and quality of life in patients with chronic heart failure. Methods PubMed, The Cochrane Library, EMbase, CNKI, Wanfang Data, VIP and CBM databases from January 1, 2010 to October 1, 2022 were searched by computer for the randomized controlled trial (RCT) about the intervention of EECP in patients with heart failure. Two researchers independently screened literature and extracted data. The meta-analysis was performed by RevMan 5.3. Results Nineteen RCTs were included. After EECP treatment, 6-minute walk distance (MD=57.37, 95%CI 40.89 to 70.85, P<0.001) and left ventricular ejection fraction improved (SMD=0.85, 95%CI 0.55 to 1.14, P<0.001). B-type natriuretic peptide decreased significantly (SMD=−0.67, 95%CI −1.09 to −0.25, P=0.002). The left ventricular end diastolic diameter (MD=−7.77, 95%CI −11.49 to −4.04, P<0.001), and the left ventricular end systolic diameter were significantly reduced (MD=−8.53, 95%CI −13.47 to −3.60, P<0.001). The quality of life of patients was improved (MD=16.34, 95%CI 0.59 to 32.10, P=0.04). Conclusion EECP can improve the exercise ability and the quality of life in patients with heart failure. However, more and larger well-designed RCTs are still needed to verify this conclusion.
ObjectiveTo analyze the impact of disaster prevention and preparedness education courses on college students’ awareness, actions and abilities of disaster prevention and preparedness, so as to provide a reference for the establishment and optimization of disaster education-related courses in colleges.MethodsStudents who took the optional course “Disaster Preparedness Education” of Sichuan University in the fall semester of 2019 to 2020 were included. Questionnaires were issued before and after the course to compare the differences in awareness, actions and abilities of disaster prevention and preparedness of college students before and after the course. We also analyzed the differences between college students of different genders and college students of different grades.ResultsFinally, 148 college students were included. After the course, college students’ awareness scores (9.24±0.61 vs. 6.11±0.52), action scores (6.89±0.70 vs. 2.65±0.58) and ability scores (33.73±1.61 vs. 18.55±1.88) of disaster prevention and preparedness were improved compared to those before the course, and the differences were statistically significant (P<0.05). Before the course, boys’ disaster prevention and preparedness awareness score was higher than that of girls (6.48±0.56 vs. 5.23±0.44), the difference was statistically significant (P<0.05); there was no significant difference in the scores of actions or abilities of disaster prevention and preparedness between boys and girls (P>0.05). After the course, there was no statistically significant difference in any of the scores between boys and girls (P>0.05). Before and after the course, there was no statistically significant difference in any of the scores between the senior college students and the lower college students (P>0.05). College students’ overall satisfaction with disaster preparedness education was relatively high, with the highest scores for teaching methods and assessment methods.ConclusionDisaster preparedness education courses have a positive effect on improving the comprehensive qualities of college students’ disaster preparedness awareness, actions, and abilities, but it is necessary to attract more college students to participate and increase the scope of the course.
ObjectiveTo evaluate the conditions of activity of daily living (ADL) and influence factors of ADL of hospitalized elderly (≥60 years old) patients. MethodsA cross-sectional study was conducted to investigate the health and ADL conditions of hospitalized elderly patients in the geriatric department of a tertiary hospital in Chongqing by ADL scale. The influence factors of ADL were analysed by using logistic regression analysis. ResultsA total of 375 hospitalized elderly patients were included. The ADL impairment rate of female was 59.60% (93/156), the one of male was 75.90% (166/219), and there was significant difference between different sex (χ2=11.169, P=0.001). The impairment rate by age were 95.40% at 60 to 69 years old, 91.40% at 70 to 79 years old, 87.20% at 80 to 89 years old, and 98.55% at above 90 years old, respectively; there was significant difference among different age groups (χ2=8.575, P=0.036). The result of logistic regression analysis showed that age was the individual risk factor of ADL (OR=0.188, 95%CI 0.085 to 0.416, P=0.000). The difficulty of walking up and down stairs occupied the highest proportion (68.80%) in 10 items of ADL scale. ConclusionHospitalized elderly patients should be equipped with specialized paramedics to minimize the difficulties of ADL, in order to improve their quality of life.
Objective To explore whether the effect of cloud rehabilitation system on motor dysfunction and activities of daily living (ADL) of stroke patients is not inferior to hemiplegia manual treatment. Methods This study adopted a multicenter randomized controlled trial design. A total of 118 stroke patients were enrolled from 5 hospitals in China between April 2018 and April 2019, and they were randomly divided into a trial group and a control group, with 59 patients in each group. The trial group adopted hemiplegia manual treatment (≥30 min per time, once a day) and cloud rehabilitation training (30 min per time, once a day), and the control group adopted hemiplegia manual treatment alone (≥30 min per time, twice a day). All patients received continuous treatment for 2 weeks, and followed up for 2 weeks after that. The Brunnstrom stage (BRS), IK exercise stage, and Modified Barthel Index (MBI) were used to evaluate the motor function and ADL before and 4 weeks after treatment. Results There was no significant difference in gender, age, course, hemiplegia side, source (inpatient/outpatient) or hospital grade between the two groups (P>0.05), which were comparable. Compared with those before treatment, there were significant improvements in the BRS (upper and lower extremities), IK exercise stages (upper and lower extremities), and MBI scores in both groups 4 weeks after treatment (P<0.05). The four-week improvements in motor function indicators (BRS and IK) of the trial group were not inferior to those of the control group (P<0.05), and there was no significant difference in MBI score between the two groups 4 weeks after treatment (F=1.498, P>0.05). Conclusion The cloud rehabilitation system is not inferior to hemiplegia manual treatment in improving the limb motor function or ADL of patients .
