ABSTRACT
Objective To investigate the correlation between mild cognitive impairment (PD-MCI) and serum homocysteine (Hcy) in patients with Parkinson's disease.Methods 85 patients with PD (43 with PD-MCI,42 with PDN) as the observation group and 43 healthy elderly patients as the control group.The demographic information,clinical and neuropsychological assessments were conducted and the Hcy of fasting venous blood were detected in all subjects.The I-Icy level and its associated factors were also analyzed in the PD group.Results Serum levels of Hcy in the PD patients((13.53±2.29) μmol/L) were higher than those in the HC group((11.77±1.56) μmol/L),the difference was statistically significant (t=4.57,P ＜0.05).There was significant difference in serum Hcy levels among HC group,PDN group ((12.85 ± 1.88) μmoL/L) and PD-MCI group((14.22±2.47) ±mol/L) (F=16.13,P＜0.01).Hcy level of the PDN group was higher than that of the HC group (P＜0.05),and PD-MCI group was higher than PDN group (P＜0.05).Serum levels of Hcy in patients with PD-MCI were significantly associated with UPDRS-Ⅲ (r=0.305),H-Y (r=0.313),LEDD (r=0.424),MMSE (r =-0.470),MoCA (r=-0.503),duration of connection test B (r =0.617) and semantic fluency tests (r=0.557) (all P＜0.05).Conclusion Elevated serum Hcy levels are expected to be biomarkers for predicting PD-MCI.
ABSTRACT
Objective To study the effect of scenario case based learning for nurse-patient communicationon empathy of un-dergraduate nursing students. Methods The undergraduate nursing students who had completed the basic nursing courses and the course of"communication in nursing"were enrolled as participants.Seventy-two students recruited in 2013 were assigned as the control group,where only individual guidance was given before taking examination;while eighty-nine students recruited in 2014 as the inter-vention group,where a self-compiled Collection of Scenarios for Nurse-Patient Communication was given when they were preparing for the final examination and the students were required to give their own communication plans based on the scenario cases from the collec-tion.The two groups were compared in view of empathy. Result The intervention group were better in empathy ability assessment, with statistically significant difference (P<0.001). Conclusions The scenario case based learning for nurse-patient communication makes up for the shortcomings of traditional teaching methods.It encourages nursing students to think from the patients'perspective and improves the empathy ability of students.
