ABSTRACT
Depression is characterized by mental retardation, interest blank, hypoactivity, anxiety, appetite loss, sexual dysfunction, sleep disorders and other symptoms. The incidence of depressed patients has demonstrated an upward trend in recent years. Antidepressant drugs are commonly used in modern medicine, but they have the side effect of drug resistance. This study aims to explore the effect of acupuncture stimulation on expressions of macrophage-related cytokines in mice with depression induced by chronic unpredictable mild stress [CUMS], and to explore the underlying immunological mechanism. The CUMS model was successfully developed. The secretion of nuclear transcription factor-kappa B [NF-kappa B] and interleukin [IL]-8 increased significantly in the modeling group compared with the blank control group [P<0.05]. However, no significant difference of tumor necrosis factor-alpha [TNF-alpha] concentration was found [P>0.05]. After acupuncture treatment, the behavior indicator was improved and meanwhile, the levels of TNF-alpha, NF-kappa B, IL-8 decreased significantly compared with the sham group [P<0.05]. Depression mice were given treatment of acupuncture, and the effect of behavior change was observed and the content of macrophage cytokine production was measured, respectively. These findings suggested that inflammatory cytokines secreted by peritoneal macrophages increased significantly in mild depression mice, which can be improved by stimulation with acupuncture
ABSTRACT
Objective To explore the main influencing factors of recurrent stroke.Methods 2 065 new stroke patients were selected as study populations.The recurrent stroke status and kinds of influencing factors were followed up.The follow-up study time was 3 years.Single factor and multi-factor analysis methods were carried out for influencing factom of recurrent stroke by Cox proportional hazaIds regression models.Results By the end.1 881 pa%);45 patients were recurrent in 6accepted visit,184 were lost follow-up.327 patients were recurrent(17.38tients months(13.76%);68 patients were recurrent during 6 months to 1 year(20.80%);97 patients were recurrent during 1 year to 2 years(29.66%);117 patients were recurrent after 3 years(35.78%).Single factor Cox regression analysis:The risk factors of recurrent stroke were advanced age(RR=1.48),smoking(RR=1.35),fat intake(RR=1.83),hypertension history(RR=2.54),diabetes history(RR=1.72),high lipemia(RR=1.83),stroke family history(RR=2.62),depression(RR=1.84),life events(RR=2.53),fibrinogen(RR=1.75),carotid plaques(RR=2.68);The protecting favors of recurrent stroke were female(RR=0.64),sports(RR=0.33),social support(RR=0.36).Multi-factor Cox regression analysis:the risk factors of recurrent stroke were hypertension history(RR=1.86),high lipemia(RR=1.95),stroke family history(RR=2.62),life events(RR=2.38),carotid plaques(RR=2.77);The protecting factors of recurrent stroke were sports(RR:0.35),social support(RR=0.32).Conclusion The prevention of hypertension history,high lipemia,the family history of stroke,more supports and the high ability of answering life events could help to prevent the recurrent stroke.
