RESUMEN
OBJECTIVE@#This study aimed to investigate the therapeutic effects of Xiaoyao San (XYS), a herbal medicine formula, on exercise capacity and liver mitochondrial metabolomics in a rat model of depression induced by chronic unpredictable mild stress (CUMS).@*METHODS@#A total of 24 male SD rats were randomly divided into four groups: control group (C), CUMS control group (M), Venlafaxine positive treatment group (V), and XYS treatment group (X). Depressive behaviour and exercise capacity of rats were assessed by body weight, sugar-water preference test, open field test, pole test, and rotarod test. The liver mitochondria metabolomics were analyzed by using liquid chromatography-mass spectrometry (LC-MS) method. TCMSP database and GeneCards database were used to screen XYS for potential targets for depression, and GO and KEGG enrichment analyses were performed.@*RESULTS@#Compared with C group, rats in M group showed significantly lower body weight, sugar water preference rate, number of crossing and rearing in the open field test, climbing down time in the pole test, and retention time on the rotarod test (P < 0.01). The above behaviors and exercise capacity indices were significantly modulated in rats in V and X groups compared with M group (P < 0.05, 0.01). Compared with C group, a total of 18 different metabolites were changed in the liver mitochondria of rats in M group. Nine different metabolites and six metabolic pathways were regulated in the liver mitochondria of rats in X group compared with M group. The results of network pharmacology showed that 88 intersecting targets for depression and XYS were obtained, among which 15 key targets such as IL-1β, IL-6, and TNF were predicted to be the main differential targets for the treatment of depression. Additionally, a total of 1 553 GO signaling pathways and 181 KEGG signaling pathways were identified, and the main biological pathways were AGE-RAGE signaling pathway, HIF-1 signaling pathway, and calcium signaling pathway.@*CONCLUSION@#XYS treatment could improve depressive symptoms, enhance exercise capacity, positively regulate the changes of mitochondrial metabolites and improve energy metabolism in the liver of depressed rats. These findings suggest that XYS exerts antidepressant effects through multi-target and multi-pathway.
RESUMEN
Objective:To analyze risk factors and prognostic risk factors in aged patients with coronary heart disease (CHD).Methods:Clinical data of 412 aged patients,who were suspected of CHD in our hospital,were retrospec-tively analyzed.According to results of coronary angiography,they were divided into CHD group (n=283 )and non-CHD group (n=129);risk factors and prognostic risk factors for aged CHD patients were analyzed.Results:Compared with non-CHD group,there were significant rise in percentages of >80 years (13.95% vs.28.98%),di-abetes mellitus (DM,37.98% vs.66.78%)and smoking history (32.56% vs.59.72%)in CHD group,levels of to-tal cholesterol [TC,(5.06±1.53)mmol/L vs.(5.41±1.36)mmol/L],triglyceride [TG,(1.53±0.82)mmol/L vs.(2.02±0.95)mmol/L]and low density lipoprotein cholesterol [LDL-C,(2.05±0.86)mmol/L vs.(2.57 ±1.15)mmol/L],and significant reduction in high density lipoprotein cholesterol level [HDL-C, (1.65 ±0.52) mmol/L vs.(0.86±0.38)mmol/L]in CHD group,P <0.05 or <0.01. Multi-factor Logistic regression analysis indicated that age,DM,hypertension history,smoking,high total cholesterol (TC)and hypertriglyceridemia were independent risk factors for CHD (OR= 1.38 ~8.65,P <0.05 or <0.01 );while serum total bilirubin and high density lipoprotein cholesterol were independent protective factors for CHD (OR=0.224,P =0.002);multi-factor Cox model analysis indicated that smoking history,high TC and hypertension were risk factors affecting prognosis of CHD patients (RR= 1.563 ~ 2.315,P < 0.05 all).Conclusion:In clinic,attention should be paid to reduce or eliminaterelated risk factors of aged CHD patients to improve prognosis.
