An analysis of relationship between self perceived burdenand self efficacy, coping style in patients with chronic obstructive pulmonary disease / 中国医师杂志

Objective To investigate the characteristics of self perceived burden (SPB) in patients with chronic obstructive pulmonary disease (COPD) and explore the relationship between the perceived burden and self-efficacy,coping style.Methods A total of 96 cases with COPD in our hospital from January 2015 to June 2017 were enrolled in the study.The clinical data of patients were retrospectively analyzed.The patients were surveyed by self perceived burden scale,self-efficacy scale and coping style scale.The relationship between self perceived burden and self efficacy,coping style were investigated.Results The self perceived burden score of COPD patients was (33.76 ± 7.65) points with moderate level.The symptom management self-efficacy,common disease management self-efficacy score of COPD patients were (8.13 ± 1.09) and (8.22 ± 1.13) respectively with moderate self-efficacy.The total score of coping style in COPD patients was (35.09 ± 10.83) points with positive coping style.The each dimension and the total score of self perceived burden were negatively correlated with positive coping style in COPD patients (P ＜ 0.05),and positively correlated with negative coping styles (P ＜ 0.05).The total score of coping style had no significant correlation with perceived burden scores (P ＞ 0.05).The each dimension and the total score of self perceived burden were negatively correlated with the each dimension scores and total scores of self-efficacy in COPD patients (P ＜ 0.05).Conclusions There are significant correlation between SPB and self-efficacy and coping style in COPD patients.Medical staff should strengthen communication with patients,and guide them with positive coping style in the face of disease,which can effectively improve their self-efficacy and reduce the self perceived burden and promote physical and mental health.

Rapid test of heavy metal cadmium content in rice of some region by X-ray fluorescence spectrometer / 医疗卫生装备

Objective To determinate the heavy metal cadmium content in rice to ensure food safety.Methods Several brands and batch numbers of rice were collected and divided into groups A and B.Group A contained 24 pieces of rice from the canteens,and group B involved in 22 pieces from the farm product markets.Cadmium content in rice was detected quantitatively with X-ray fluorescence spectrometer,and then evaluated according to GB 2762-2012 which determined rice was not qualified in case cadmium content was more than 0.2 mg/kg.Results Group A had cadmium content between 0.00 and 0.477 mg/kg,the times of ultra standard being 2.385 and the disqualification rate being 29.2％ (7/24),and group B had cadmium content between 0.065 and 0.619 mg/kg,the times of ultra standard being 3.095 and the disqualification rate being 68.2％ (15/22).Excessive cadmium content in rice occurred in both canteens and markets,while the canteens was better than the markets.Conclusion X-ray fluorescence spectrometer detects cadmium content in rice rapidly and simply,and is worthy promoting in elementary facilities.
