ABSTRACT
Objective:To explore the mediating effect of expectations regarding aging between social support and frailty in elderly patients with chronic obstructive pulmonary disease (COPD), so as to promote better health education among medical staff and improve patients′ ability to cope with frailty.Methods:This was a cross-sectional study, the convenience sampling method was used to select 258 elderly COPD patients hospitalized in the Department of Respiratory Medicine and Geriatrics of Xinjiang Uygur Autonomous Region People′s Hospital from November 2021 to April 2022. They were investigated by the general information questionnaire, Fried Scale, Social Support Scale and Expectations Regarding Aging-21. Analyzed the correlation among social support, expectations regarding aging and frailty. AMOS 26.0 was used to investigate the mediating effect of expectations regarding aging between social support and frailty in elderly COPD patients.Results:The score of social support, expectations regarding aging and frailty in elderly patients with COPD was (30.45 ± 5.57), (35.25 ± 6.28) and (2.34 ± 1.71)points, respectively. There was negative correlation between social support and frailty in elderly COPD patients ( r=-0.541, P<0.01), while positive correlation between social support and expectations regarding aging ( r=0.477, P<0.01). The negative correlation between social support and expectations regarding aging ( r=-0.536, P<0.01). Expectations regarding aging played a partial mediating role between social support and frailty, with mediating effect value of -0.229, accounting for 35.39% of the total effect. Conclusions:Expectations regarding aging is a mediator variable between social support and frailty in elderly COPD patients. Health care providers can alleviate or even reverse patients' debilitating condition by improving their expectations regarding aging and social support.
ABSTRACT
Objective To investigate the residents' acceptance and the influencing factors of the hierarchical medical system in Xuzhou, and to suggest on effective system implementation. Methods Xuzhou residents free of cognitive impairment and over 18 years old were sampled for questionnaire survey in July-August 2016, to study their acceptance of their basics and acceptance of the system. 1 550 questionnaires were distributed, and 1 473 valid ones were recovered. The count data were expressed as constituent ratio, and χ2test was used for single-factor analysis, with binary logistic regression analysis for multi-factor analysis. Results 71. 0% of the residents embraced this system. Their acceptance varies significantly with their age, place of residence, education, annual average monthly income, self-rated health status, physical examination experience, conditions of chronic diseases, medical visit experience at primary healthcare institutions, and their awareness of the system (P<0.05). Conclusions The acceptance of the system by Xuzhou residents needs to be elevated, by means of greater promotional efforts, capacity building for primary institutions, so as to fully leverage the system to serve the residents.
ABSTRACT
Background Immediately ocular rinsing is a key step for the prevention of eye tissue damage after acute chemical bums.A good ophthalmic rinsing solution can neutralize chemical substance and improve the prognosis of patients.Objective This study attempted to evaluate the therapeutic effect of self-made citric aciddisodium hydrogen phosphate buffer and citric acid-disodium hydrogen phosphate-potassium chloride buffer on corneal chemical burns in mice.Methods Citric acid-disodium hydrogen phosphate buffer solution (solution 1) and citric acid-disodium hydrogen phosphate-potassium chloride buffer solution (solution2) with the pH 7.4 were prepared.One hundred and twenty clean male C57 mice aged 6-8 weeks were randomized to two groups,and filter papers containing 1 mol/L H2SO4 or 0.15 mol/L NaOH were attached to the central corneas of the right eyes to create the acid or alkali burning models.Then the eyes were immediately rinsed by 40 ml solution 1,tap water or solution 2 according to the grouping and the model eyes without rinsing served as the control group.The corneal opacity was examined by slit lamp microscope and scored in 3,7 and 14 days after modeling.The percentages of corneal fluorescein staining,corneal neovascularization and corneal ulcer were analyzed.The study protocol was approved by Experimental Animal Ethic Commission of Second Military Medical University.Results In the corneal acid burning models,the number of eye with corneal opacity scored 1 in the solution 1 group,tap water group and solution 2 group was significantly more than that in the non-rinsing group in 3,7 and 14 days after modeling (all at P＜0.01);In 3 days after modeling,the numbers of eye scored 1 were more in the solution 1 group than those in the tap water group and solution 2 group (x2 =11.000,P =0.001;x2 =4.000,P =0.046).There were no differences in the eye number of different corneal opacity scores in 14 days after acid burning (all at P＞0.05).In 3,7 and 14 days after corneal alkali burning,the number of eyes with corneal opacity scored 1-2 was significantly increased in the solution 1 group,tap water group and solution 2 group compared with non-rinsing group (all at P＜0.01).The percentage of corneal ulcer in the solution 1 group,tap water group and solution 2 group was 7％,27％ and 13％,respectively,which was significantly lower than 73％ in the non-rinsing group (P =0.000,0.027,0.003),and no significant differences were seen in various time points after corneal alkali burning (all at P＞O.05).Corneal neovascularization occurred in 50％ mice in non-rinsing group in 14 days after acid burning.However,no neovascularization was seen in the mice of the solution 1 group,tap water group and solution 2 group in both acid and alkali burning mice.Conclusions Citric aciddisodium hydrogen phosphate buffer (pH 7.4) appears to be an effective emergency rinsing solution for corneal chemical burns and the rinsing solution with or without potassium chloride is not obviously affected to the prognosis of corneal chemical burns in the mice.
ABSTRACT
Objective To investigate the inpatients' evaluation of quality nursing care and disucss different data collecting methods on patients's evaluation of quality nursing care. Methods Patients measure up to standard (82 cases) were divided into the questionnaire group and the interview group with 41 patients in each group. The questionnaire investigation was carried out in the questionnaire group by applying 4 themes of quality nursing care. The interview group used structured interview instead. The results of the two methods were compared and analyzed. Results The score of quality nursing care of the questionnaire group was higher than that of the interview group (P<0.01) in evaluating health education method. In humanistic environment patients in the questionnaire group thought nurses could protect their privacy, respect their personality and treat them and their family members kindly. Besides visiting institution was reasonable. All of these were the demonstration of quality nursing care. The above results were different from those of the interview group (P<0.01). Conclusions Patients had comprehensive requirement on quality nursing care. Nurses should, use this as reference, regulate their service behavior and improve nursing quality.
