The prevalence of MCI affected by sex, age,education, which was lower in eastern than that in western China.

The prevalence of depressive symptoms among the older in China was a little high, and it was varied by gender, age, area, and education level.

Statins are a class of medications that reduce cholesterol by inhibiting 3-hydroxy-3-methylglutaryl-coenzyme A reductase, which were thought to have a positive impact on dementia. We carried out the present meta-analysis to investigate whether statins might be associated with a reduction on risk of dementia. We carried out a meta-analysis of prospective cohort studies to examine the risk of dementia associated with statins. Ovid-Medline database, PubMed database, Springer Link database and Google Scholar in English search were carried out for relevant studies. Selected studies had to describe an original study defined by strict screening and diagnostic criteria. We included eight prospective cohort studies that reported relative risks with 95% confidence intervals for the association of statins and dementia risk. A random effects model was used to calculate the summary risk estimates. The studies eligible for analysis involved 2851 cases and 57020 participants. The summary relative risk of dementia for the use of statins was 0.62 (95% confidence interval 0.43-0.81), with evidence of heterogeneity (P = 0.001, I 2 = 70.8%). Findings of the present meta-analysis show that statin use was associated with a reduced risk of dementia. Geriatr Gerontol Int 2013; 13: 817-824.

We performed a meta-analysis to evaluate the effect of home exercise programmes on body function after hip fractures. A computerised literature search was performed for published trials in PubMed, EMBASE, CENTRAL, and Cochrane Database of Systematic Reviews. Randomised trials were selected investigating home-based exercise programmes vs usual care without home-based exercise in hip fracture patients. Physical health (measured by Short Form 36), normal gait speed, fast gait speed, balance, instrumental activities of daily living (IADL), activities of daily living (ADL), lower extremity strength, leg strength in fractured leg, leg strength in non-fractured leg, and Six-Minute Walk Test (6MWT) per randomised patient were measured as outcomes. Eleven randomised controlled trials of 1068 subjects were included, 533 in the homebased exercise group and 535 in the control group. The results of this meta-analysis showed that the home-based exercise programmes were not significantly associated with physical health, normal gait speed, fast gait speed, balance, IADL, ADL, and lower extremity strength but were significantly associated with leg strength in the fractured leg, leg strength in the non-fractured leg, and 6MWT. The home-based exercise programme had a positive, although not significant, effect on physical function after hip fracture. Low-intensity training and poor patient compliance are unavoidable problems in home-based exercise rehabilitation. A more task-oriented rehabilitation programme might possibly yield more benefits for disability outcomes.
