Objective To examine the independent effect of depression on activities of daily living of patients with mild cognitive impairment (MCI). Methods Data were obtained through the face-to-face interview. Totally 154 elderly patients that were screened from 552 old people by the Montreal Cognitive Assessment (MoCA) were diagnosed as MCI. They were investigated with the Geriatric Depression Scale, and instrumental ability of daily living (IADL) were measured by the Functional Activities Questionnaire. The effect of depression on IADL of patients with MCI was analyzed by logistic regression analysis. Results The prevalence of depressive symptoms among Chinese elders with MCI was 31.82%. The scores of Medical Outcomes Study Social Support Survey, and Functional Activity Questionnaire of depression group and non-depression group were significantly different (P<0.05) . Logistic regression analysis showed that scores of Functional Activity Questionnaire was positively associated with the scores of Memory Inventory for the Chinese (OR=1.36, 95% CI: 1.15-1.61) and depression (OR=6.19, 95% CI:2.07-18.55) . Conclusion The prevalence of depression in elderly patients with MCI was high. Depression would significantly reduce the IADL of the old patients with MCI. Medical workers should be aware of the extent and impact of depressive symptoms in MCI and take active measures in evaluating and treating the depressive symptoms.

OBJECTIVETo investigate the effects of chronic stress on the spatial learning-memory and the role of glial cell line-derived neurotrophic factor (GDNF) of prefrontal cortex (PFC) and hippocampus (HP) in different age mice.
METHODSThe chronic stress model mice in 21 days with multiple chronic unpredictable stressors were applied. The spontaneous behavior and spatial learning-memory ability of mice were tested, using Open field and Morris water maze task, and the expression of GDNF in HP and PFC were detected by immunohistochemical method.
RESULTSCompared with young mice, the spontaneous behaviors were significantly decreased and the spatial learning-memory function were significantly decreased (P < 0.05, P < 0.01) in aged mice. The GDNF expression in the CA3, DG of HP and PFC were significantly reduced in aged mice (P < 0.05, P < 0.01). After chronic stress, the spontaneous behaviors were remarkably decreased and the ability of spatial learning-memory of the stress group mice were significantly decreased (P < 0.05, P < 0.01) compared with those of the control group mice. The expression of GDNF in HP and PFC were remarkably reduced (P < 0.05, P < 0.01) in stress group mice. The aged stress mice had more serious changes after chronic stress.
CONCLUSIONThe brain aging and chronic stress in mice causes behavioral changes and the damage of spatial learning-memory function, and which may be nearly related to the expression of GDNF in HP and PFC.

This study was aimed to evaluate the proliferation-associated antigen Ki-67 expression in diffuse large B cell lymphoma (DLBCL) and its clinical significance. The Ki-67 expression and its correlation with prognosis in 50 patients with DLBCL treated with rituximab plus CHOP (R-CHOP) between January 2008 and December 2010 were analyzed retrospectively. The results indicated that there was no significant relationship between Ki-67 expression and clinical features, including age, sex, staging, B symptoms, LDH level, IPI, extranodal site involvement, presence of bulky tumors (>10 cm in diameter), bone marrow involvement, GCG nor GCB type, or response to first line treatment. The median survival was 50 months and 15 months in low Ki-67 expression group (<85%) and in high Ki-67 expression group ( ≥ 85%) respectively. The overall survival (OS) and progress-free survival (PFS) in low Ki-67 expression group were obviously longer than that in high Ki-67 expression group (P = 0.001; P = 0.027). In univariate analysis, the clinical factors associated with OS included Ann Arbor staging and Ki-67 expression. The clinical factors associated with PFS included Ann Arbor staging. IPI and Ki-67 expression. In multivariate analysis. The Ki-67 expression level was an independent prognostic factor for OS (HR = 4.90; 95% CI, 1.456-16.511; P = 0.0103). It is concluded that Ki-67 expression level seems to be an effective marker for evaluation of DLBCL prognosis.
