ABSTRACT

OBJECTIVES@#The use of anticholinergic drugs in the elderly may lead to negative events such as falls, delirium, urinary retention and cognitive decline, and the higher the number of anticholinergic drugs use, the more such negative events occur. This study aims to analyze the risk factors associated with the prescription of total anticholinergic drugs in elderly outpatients and evaluate the rationality of anticholinergic drugs, and to provide a reference for reducing the adverse effects of anticholinergic drugs.@*METHODS@#A list of drugs with anticholinergic activity based on the Beers criteria was established. The basic information (such as age and gender), clinical diagnosis, and medications of elderly outpatient were extracted from hospital electronic medical records, and the Anticholinergic Cognitive Burden (ACB) Scale was used to calculate the anticholinergic burden for each patient. Logistic regression analysis was used to identify the potential risk factors for the occurrence of problems such as multiple medication and insomnia.@*RESULTS@#A total of 1 840 prescriptions for elderly patients were reviewed. Of these patients, ACB score was more than or equal to 1 in 648 (35.22%) patients. Number of prescription medication (95% CI: 1.221 to 1.336) and insomnia (95% CI: 3.538 to 6.089) were independent factors affecting ACB scores (both P<0.01). Medications for patients of ACB scores were most commonly treated with the central nervous system drugs (such as alprazolam and eszopiclone) and for the cardiovascular system drugs (such as metoprolol and nifedipine).@*CONCLUSIONS@#There is a high rate of ACB drugs use in geriatric patients, and the clinical focus should be on multiple medication prescriptions, especially on the central nervous system drugs (such as alprazolam and eszopiclone) and cardiovascular system drugs (such as metoprolol and nifedipine). The prescription review should be emphasized to reduce adverse reactions to anticholinergic drugs in elderly patients.

ABSTRACT

Objective To investigate the mechanism of EMT and invasion promoted by miR-21 in prostate cancer cells. Methods The sequence of miR-21 mimic/inhibitor was firstly designed and synthesized. Then miR-21 mimic/inhibitor and its control were transfected into prostate cancer cells C4-2 and DU145, respectively. And cells were collected for mRNA isolation and RT-qPCR analysis for miR-21 and FOXOl. FOXOl, E-cadherin and N-cadherin were detected by Western blot, and the invasion of prostate cancer cells were detected by transwell assays. Results The expression of miR-21 increased in both C4-2 and DU145 after transfection, and the expression of FOXOl mRNA increased at the same time (P<0.01).The expression of miR-21 and FOXOl mRNA in C4-2 and DU145 was decreased by miR-21 inhibitor(P< 0.05). The protein expression of FOXOl and N-cadherin in C4-2 and DU145 increased after the treatment of miR-21, while that of E-cadherin decreased. The protein expression of FOXOl and N-cad-herin in C4-2 and DU145 decreased after the treatment of miR-21 inhibitor, while that of E-cadherin increased. The invasive level in C4-2 and DU145 increased after the treatment of miR-21, while that decreased after the treatment of miR-21 inhibitor. Conclusion MiR-21 promotes EMT and invasion by inducing FOXOl in prostate cancer cells.
