Objective This study evaluated whether liver ischemic preconditioning has delayed protective effect on liver ischemia-reperfusion injury and probe into the protective mechanism.Methods 36 wistar rats were randomly divided into two groups, group A:ischemic preconditioning,Group B:Control. The group A rats were subjected to liver ischemic preconditioning,While group B rats were subjected only laparotomy.After 48 hours,Liver tissue samples were abstained to detect the expression of HSP70.Occlusion the inflow vessels to the left and median lobes 45-minute then reperfuse 90-minute.Liver tissue samples were abstained to detect the expression of TNF-?.Serum ALT was detected before ischemia and after 90-minute reperfusion.Results The serum ALT level in group A is much lower than that in group B (P

Objective To investigate the incidence of insomnia and its influencing factors in the outpatients with cardiovascular diseases in a general hospital.Methods A total of 956 consecutive cases of the outpatients was collected from March 2016 to September in the department of cardiology patients in this general hospital.Insomnia was diagnosed with the 2012 Chinese adult insomnia diagnosis and treatment guidelines.All subjects underwent clinical examination,generalized anxiety scale (GAD-7),patient health questionnaire depression scale (PHQ-9),and self-made demographic sociology information questionnaire.Results A total of 925 patients with completed data was included in the analysis data.The insomnia incidence rate was 51.4％.The insomnia incidence rates were 57.8％ and 37.6％ in the patients with and without cardiovascular diseases.The difference was statistically significant (P ＜ 0.01) between both groups.The insomnia incidence rates in the patients with hypertension,coronary heart disease,arrhythmia,hypertension combined with coronary heart disease and other cardiovascular diseases were 50.8％,56.3％,53.2％,63.0％,and 54.3％,respectively.There were significant differences between the groups (P ＜ 0.05).The incidence of anxiety or depressive symptoms was 44.5％ in all investigators.Insomnia incidence rates were 75.6％ and 32.0％ in the subjects with and without anxiety or depressive symptoms.The difference was statistically significant (P ＜ 0.01) between both groups.Multivariate logistic regression analysis showed that gender,type A personality,family income satisfaction,cardiovascular diseases and anxiety/depression were independent factors to affect the occurrence of insomnia.Conclusions The insomnia incidence rates was high in the outpatients from the department of cardiology of general hospital.The main factors that affect the occurrence of insomnia include psychological,social aspects,and cardiovascular diseases.
