Enhanced External Counterpulsation

Traditional enhanced external counterpulsation (EECP) used for the clinical treatment of patients with coronary heart disease only assesses diastolic/systolic blood pressure (Q = D/S > 1.2). However, improvement of the hemodynamic environment surrounding vascular endothelial cells of coronary arteries after long-term application of EECP is the basis of the treatment. Currently, the quantitative hemodynamic mechanism is not well understood. In this study, a standard 0D/3D geometric multi-scale model of the coronary artery was established to simulate the hemodynamic effects of different counterpulsation modes on the vascular endothelium. In this model, the neural regulation caused by counterpulsation was thoroughly considered. Two clinical trials were carried out to verify the numerical calculation model. The results demonstrated that the increase in counterpulsation pressure amplitude and pressurization duration increased coronary blood perfusion and wall shear stress (WSS) and reduced the oscillatory shear index (OSI) of the vascular wall. However, the impact of pressurization duration was the predominant factor. The results of the standard model and the two real individual models indicated that a long pressurization duration would cause more hemodynamic risk areas by resulting in excessive WSS, which could not be reflected by the change in the Q value. Therefore, long-term pressurization during each cardiac cycle therapy is not recommended for patients with coronary heart disease and clinical treatment should not just pay attention to the change in the Q value. Additional physiological indicators can be used to evaluate the effects of counterpulsation treatment.

Abstract Background Seaweeds are a famous traditional food resource in some countries containing different types of secondary metabolites. These marine organisms have shown different biological activities. The aim of this study was to investigate the effects of hexane and methanol extracts of Sargassum plagyophylum on depression. Methods Sargassum plagyophylum was collected from Persian Gulf. The plant was extracted by maceration with methanol-ethyl acetate solvent. The extract was evaporated and partitioned by hexane and methanol solvents. The two partitions were administered i.p. to male mice either a single dose or for 7 days. Depression was evaluated by the forced swimming test (FST) which higher immobility time indicates depressive-like behavior. Results The immobility time during FST decreased significantly by all the doses of the hexane partitions (notably 40 mg/kg; 10 s ± 2 vs. 114 s ± 12 control group). However, only the lowest dose (20 mg/kg) of the methanol partition reduced immobility time during FST (23 s ± 8, p<0.001). Following the long term administration both of the partitions reduced the immobility time in FST (hexane 27 s ± 11, methanol 70 s ± 14, p<0.05 vs. control 140 s ± 14). Conclusion The hexane partition showed antidepressant effects not only by long-term administration but also by the single dose during FST. The 7 days therapy with methanol partition also induced antidepressant behavior, but only the lowest single dose reduced immobility in FST. The methanol partitions possibly have certain substance that interfered with behavior in the FST. Therefore, S. plagyophylum should be considered for further antidepressant studies.

Long Term Mortality

Background. Coronary heart disease (CHD) is caused by the blockage or spasm of coronary arteries. Evidence shows that liver disease is related to CHD. However, the correlation between the Model for End-Stage Liver Disease (MELD) score and outcomes in patients after percutaneous coronary intervention (PCI) was unclear. Method. A retrospective cohort study involved 5373 patients with coronary heart disease after PCI was conducted from January 2008 to December 2016. Participants were classified to four groups according to the MELD score by quartiles. The primary endpoint was long-term mortality including all-case mortality (ACM) and cardiac mortality (CM). Secondary endpoints included bleeding events, readmission, major adverse cardiovascular events (MACE), major adverse cardiovascular, and cerebrovascular events (MACCE). The longest follow-up time was almost 10 years. Results. There were significant differences in the incidences of ACM ( p = 0.038 ) and CM ( p = 0.027 ) among the four MELD groups, but there was no significant difference in MACEs ( p = 0.496 ), MACCEs ( p = 0.234 ), readmission ( p = 0.684 ), and bleeding events ( p = 0.232 ). After adjusting the age, gender, smoking, drinking status, and diabetes by a multivariable Cox regression analysis, MELD remains independently associated with ACM (HR:1.57, 95%CI 1.052–2.354, p = 0.027 ) and CM (HR:1.434, 95% CI 1.003–2.050, p = 0.048 ). Conclusion. This study indicated that the MELD score had a strong prediction for long-term mortality in CHD patients who underwent PCI.
