Objective To explore the risk factors of postoperative activities of daily living in elderly patients after hip fracture. Methods By convenience sampling,from October 2013 to June 2015,150 elderly patients having undergone surgery after hip fracture were selected,with data of 141 cases finally collected. Gender,age,underlying diseases,surgical procedures,postoperative complications,ambulation time,whether walking with aids,family caregivers and reexamination conditions were recorded for evaluation of the patients about their activities of daily living half a year after the surgery. Mean comparison and chi-square test were used for univariate analysis about the above factors and Logistic regression analysis was used to identify possible risk factors. Results It was shown in univariate analysis that recovery of postoperative activities of daily living was influenced by age,surgical procedures,postoperative complications,ambulation time,walking aids,etc. (P< 0.05);it was shown in multivariate logistic regression that age (OR=1.065,95%CI:1.010-1.124, P=0.020),surgical procedures (OR=2.900,95%CI:1.200-7.008,P=0.018),postoperative complications (OR=6.366,95%CI:2.592-15.632,P< 0.001),ambulation time (OR=2.684,95%CI:1.133-6.359,P=0.025) and walking aids (OR=5.796,95%CI:1.542-21.780,P=0.009) were risk factors of postoperative daily living ability in elderly patients after hip fracture. Conclusions Old age,developing internal fixation surgery after incision,postoperative complications, walking more than 3 months after operation or walking without aids affect postoperative activities of daily living in elderly patients after hip fracture,thus affecting their quality of life, which makes it necessary for nursing staff to focus on risk factors for positive prevention and intervention.

Objective: To investigate the difference of temporary memory system and brain biochemical metabolites between patients with depressive obsessive-compulsive disorder and simple obsessive-compulsive disorder. Methods: From June 2017 to June 2018, 31 patients with simple obsessive-compulsive disorder, 33 patients with depressive obsessive-compulsive disorder and 25 healthy volunteers were selected as subjects. The temporary memory ability of the three groups was tested by n-back, Stoop color association test and digital breadth test. Three brain sublimation metabolites, N-acetylaspartate acid (NAA), choline complex (Cho) and creatine (Cr), were detected by proton magnetic resonance pop (¹H-MRS) in bilateral prefrontal white matter, anterior cingulate cortex and anterior cingulate cortex. The ratio of NAA/Cr and Cho/Cr was calculated with Cr as reference material. Results: The scores of Yale-brown obsessive-compulsive severity scale (Y-BOCS) and Hamilton depression rating scale 24 (HAMD24) in the patients with simple obsessive-compulsive disorder and depression obsessive-compulsive disorder group were significantly higher than those in the healthy control group, and the scores of HAMD24 in the patients with depression obsessive-compulsive disorder group were significantly higher than those in the patients with simple obsessive-compulsive disorder group, with statistically significant difference (P<0.05). The number of correct n-back in the simple obsessive-compulsive group and the depressive obsessive-compulsive group was significantly lower than that in the healthy control group (P<0.05). The digital span test (DST) scores of the patients in the simple obsessive-compulsive disorder group and the depressive obsessive-compulsive disorder group were (14.37±2.96) and (12.39±2.14), which were significantly lower than those in the healthy control group (17.46±3.28) (P<0.05). There was no significant difference in NAA/Cr and Cho/Cr between the three groups (P>0.05). Compared with the healthy control group, the NAA/Cr value of bilateral prefrontal white matter in the simple obsessive-compulsive group and the depression obsessive-compulsive group was significantly lower, and the difference was statistically significant (P<0.05). Conclusions Both patients with simple obsessive-compulsive disorder and depressive obsessive-compulsive disorder had speech memory impairment and bilateral prefrontal white matter nerve function decline, while depressive obsessive-compulsive disorder patients also had central executive memory impairment.
