Objective To explore the effect of iliac artery to deep femoral artery angioplasty on the improvement of postoperative lower limb ischemic symptoms and recovery in patients with lower limb arteriosclerosis obliterans(LEASO).Methods One hundred and four LEASO patients in Dongzhimen Hospital of Beijing University of Chinese Medicine from December 2013 to July 2016 were involved in the study and they were divided into control group and observation group according to the treatment program,each group 52 cases.The control group was treated with conservative treatment,and the observation group was treated with iliac artery to deep femoral artery angioplasty.After treatment,the limb ischemic injury degree Rutherford classification and clinical efficacy of the two groups were compared,all patients were followed up for 6 months to compare the survival quality score before and 6-month after treatment.Results (1) Rutherford classification: after treatment,Rutherford classification in the observation group was significantly higher than that of the control group,the result was statistically significant (Z=2.160,P=0.031);(2) Clinical efficacy: the total effective rate in the observation group (94.23% (49/52)) was higher than that of the control group (76.92% (40/52)),the difference was statistically significant (χ2=6.310,P=0.012);(3) Life quality: before treatment,there was no significant difference between the two groups in terms of the quality of life score ((55.01±6.32) points vs.(54.89±6.14) points,t=0.098,P=0.922),but 6 months after treatment,the score of the observation group became higher than that of the control group ((69.63±7.51) points vs.(63.15±6.98) points,t=4.558,P=0.000).Conclusion The treatment of LEASO using iliac artery to deep femoral artery angioplasty can effectively improve patient''s lower limb ischemic symptoms and life quality.

Objective:To explore the mediating effect of job resources between self-efficacy and job crafting behavior of Intensive Care Unit (ICU) nurses.Methods:From March to May 2022, 629 ICU nurses from Fuwai Hospital, Chinese Academy of Medical Sciences were selected by cluster sampling as the subjects. The nurses were investigated by using the General Information Questionnaire, Job Crafting Scale (JCS) , the Copenhagen Psychosocial Questionnaire (COPSOQ) , and the General Self-Efficacy Scale (GSES) . Pearson correlation was used to analyze the correlation between ICU nurses' job resources, self-efficacy and job crafting behavior. The mediating effect model was established by AMOS software, and the mediating effect was discussed by Bootstrap test. A total of 629 questionnaires were distributed, and 555 valid questionnaires were collected, and the effective response rate was 88.24% (555/629) .Results:Among 555 ICU nurses, the scores of JCS, job resources and GSES were (77.58±12.53) , (74.35±13.37) and (27.16±5.90) , respectively. Pearson correlation analysis showed that ICU nurses' job crafting behavior was positively correlated with self-efficacy and job resources ( P<0.01) . Bootstrap mediating effect analysis showed that there was a partial mediating effect of job resources between self-efficacy and job crafting behavior of ICU nurses [β= 0.128, 95% CI (0.086, 0.177) ] , accounting for 18.7% of the total effect. Conclusions:ICU nurses' job crafting behavior is at a moderate to upper level. Job resources play a mediating role between self-efficacy and job crafting behavior. Nursing managers should focus on the job crafting behavior of ICU nurses, build a supportive work environment, pay attention to their psychological health, give them correct guidance, and improve the self-efficacy of ICU nurses.
