ObjectiveTo investigate the effects of modified Xiaoyaosan （JJXYS） on behavioral abnormalities and hippocampal mitochondrial quality control （MQC） in the rat model of post-myocardial infarction depression （PMD） and preliminarily explore its potential mechanism. MethodsA rat model of PMD was established by left anterior descending coronary artery ligation combined with chronic unpredictable mild stress （CUMS）. Rats were randomized into a control group， a model group， a fluoxetine （FLX， 10 mg·kg^-1） group， and low-， medium-， and high-dose JJXYS （JJXYS-L/M/H， 1.12， 2.24， 4.48 g·kg^-1， respectively） groups. Depressive-like behaviors were evaluated by body weight monitoring， sucrose preference test， open field test， and forced swimming test. Hematoxylin-eosin staining and Nissl staining were used to observe hippocampal histomorphology and neuronal changes. Enzyme-linked immunosorbent assay was conducted to determine the serum levels of 5-hydroxytryptamine （5-HT）， dopamine （DA）， interleukin-1 beta （IL-1β）， interleukin-6 （IL-6）， and tumor necrosis factor-alpha （TNF-α）. The mRNA levels of MQC-related genes including peroxisome proliferator-activated receptor-gamma coactivator-1 alpha （PGC-1α）， nuclear respiratory factor 1 （Nrf1）， and transcription factor A， mitochondrial （TFAM） in the hippocampal tissue were measured by real-time PCR. The expression of proteins related to the dynamin-related protein 1 （Drp1）/PTEN-induced putative kinase 1 （PINK1）/Parkin signaling pathway was determined by Western blot. ResultsCompared with the control group， the model group showed restricted body weight gain， aggravated depressive-like behaviors， declined serum 5-HT and DA levels， evident hippocampal neuronal damage and reduced Nissl bodies， as well as downregulated expression of MQC-related genes and proteins （P<0.05）. Compared with the model group， both FLX and JJXYS alleviated the above changes to varying degrees. Moreover， the JJXYS-M and JJXYS-H groups showed more pronounced effects， improving behavioral performance， restoring 5-HT and DA levels， alleviating hippocampal pathological injury， and upregulating the expression of PGC-1α/Nrf1/TFAM mRNA and Drp1/PINK1/Parkin signaling pathway-related proteins （P<0.05）. ConclusionJJXYS can significantly alleviate depressive-like behaviors and neurotransmitter imbalance in the rat model of PMD by regulating hippocampal MQC and upregulating the Drp1/PINK1/Parkin-related pathway. This study provides experimental evidence for the intervention of PMD with JJXYS.

Along with detection techniques develop continuously, sensitivity of cardiac troponin (cTn) detection becomes higher and higher.It improves diagnostic rate of patients with acute coronary syndrome,but accompanied by specificity reduction.Therefore, it's necessary to identify non-coronary heart disease that may lead to increase of cTn level.The present article made a review on manifestation of cTn in non-coronary heart disease.

Objective:To investigate current situation of overweight and obesity among population from coastal areas of Fujian province ,and study their correlation with blood pressure (BP) and blood lipids . Methods :A total of 3343≥30 years people from coastal areas of Fujian province were enrolled using cross -sectional survey .Body height and mass ,BP ,waist circumference (WC) ,blood glucose and blood lipids etc .were measured .The correlation among BP ,blood lipids and BMI were statistically analyzed . Results:Detection rates of overweight and obesity were 34.6% and 10.0% respectively .Overweight rate of men was significantly higher than that of women (40.4% vs . 30.7% , P<0.05);percentages of overweight and obese population gradually rose along with age increased before 70 years ,and it showed declining trend after 70 years .Compared with normal weight people of corresponding age , BP and WC significantly rose in overweight and obese young people (<40 years) , P<0.01 all;there were signifi‐cant rise in BP ,WC ,TC and LDL‐C levels ,and significant reduction in HDL‐C level in overweight and obese mid‐dle-aged and aged people (>40 years) , P<0.05 or <0.01. Partial correlation analysis indicated that BMI was positively correlated with WC ,SBP ,DBP ,TC ,LDL‐C and HbA1c levels ( r=0.701 ,0.218 ,0.238 ,0.068 ,0.120 , 0.135 ,P<0.01 all) ,and inversely correlated with TG and HDL‐C levels (r= -0.069 both ,P<0.01 both) .Mul‐tifactor linear regression analysis indicated that BMI was significantly correlated with WC ,sex ,age ,DBP ,HDL‐C and FBG levels .After controlling age ,sex and blood glucose etc .,binary Logistic regression analysis indicated that overweight (OR=2.283 ,95% CI 1.915~2.721) and obesity (OR=4.419 ,95% CI 3.329~5.865) were risk fac‐tors for hypertension and dyslipidemia [overweight (OR= 1.356 ,95% CI 1.160~ 1.584) ,obesity (OR= 1.691 , 95% CI 1.319~2.167 )] , P<0.01 all .Conclusion:Prevalence rates of overweight and obesity are high in coastal population in Fujian province .Percentages of hypertension ,dyslipidemia ,DM and cardiovascular risk factor aggre‐gation significantly rise among overweight and obese people ,so controlling body mass is of important significance for prevention and treatment of chronic diseases ,including hypertension ,DM and dyslipidemia etc .
