Abstract
Glutathione peroxidase (GPx) acts in co-ordination with other signaling molecules to exert its own antioxidant role. We have demonstrated the protective effects of GPx,/GPx-1, a selenium-dependent enzyme, on various neurodegenerative disorders (i.e., Parkinson's disease, Alzheimer's disease, cerebral ischemia, and convulsive disorders). In addition, we summarized the recent findings indicating that GPx-1 might play a role as a neuromodulator in neuropsychiatric conditions, such as, stress, bipolar disorder, schizophrenia, and drug intoxication. In this review, we attempted to highlight the mechanistic scenarios mediated by the GPx/GPx-1 gene in impacting these neurodegenerative and neuropsychiatric disorders, and hope to provide new insights on the therapeutic interventions against these disorders.

LongShengZhi Capsule reduces carrageenan-induced thrombosis by reducing activation of platelets and endothelial cells. Pharmacol Res 2019; 144:167-180. [PMID: 30986544 DOI: 10.1016/j.phrs.2019.04.013] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2019] [Revised: 03/31/2019] [Accepted: 04/11/2019] [Indexed: 12/17/2022]
Abstract
Formation of thrombosis is associated with activation of platelets and endothelial cells. The effect of LongShengZhi Capsule (LSZ), a traditional Chinese medicine used for treatment of vascular diseases, on thrombosis was investigated in this study. BALB/c mice were induced thrombosis by injection of carrageenan while receiving pre or simultaneous LSZ treatment. We also compared the therapeutic effects of LSZ and clopidogrel on formed thrombi. LSZ inhibited carrageenan-induced thrombi in mouse tissue vessels. In addition, LSZ but not clopidogrel reduced formed thrombi with a short time window. The reduction of thrombi by LSZ was associated with reduced serum P-selectin, reduced expression of TNF-α and P-selectin and activated matrix metalloproteinase 2 expression in tissues. In vitro, LSZ decreased thrombin-induced human platelet clot retraction which was associated with inactivation of AKT and ERK1/2. LSZ also reduced adhesion of platelets or THP-1 monocytes to human umbilical vein endothelial cells (HUVECs) induced by oxidized low-density lipoprotein or lipopolysaccharide. The anti-adherent actions of LSZ was attributed to reduction of oxidative stress, expression of platelet receptors (P2Y12, PAR4 and CD36) and AKT activity in platelets. LSZ also reduced adhesion molecules or tissue factor but activated tissue factor pathway inhibitor expression in HUVECs. Taken together, our study demonstrates the antithrombotic properties of LSZ by reducing activation of platelets and endothelial cells, and suggests its potential application in clinics.

Abstract
OBJECTIVE To explore the correlation between hemorheological variations and the expression of cell adhesion molecules in mesenteric microvessel endothelial cells after internal capsule hemorrhage. METHODS We established an internal capsule hemorrhage model. Then leukocyte-endothelium interaction was observed and hemorheological variations in mesenteric microvessels were evaluated in the following aspects: blood flow volume, diameter of microvessels, blood flow rate, and shear rate. We also measured the expression of vascular cell adhesion molecule-l and intercellular adhesion molecule-1 (ICAM-1) in mesenteric microvessel endothelial cells with immunohistochemistry stain. RESULTS Leukocyte-endothelium interaction intensified after internal capsule hemorrhage. Besides, blood flow volume and velocity decreased, diameter narrowed, and shear rate reduced. Immunohistochemical staining of vascular cell adhesion molecule-l and ICAM-1in mesenteric microvessel endothelial cells was stronger. CONCLUSIONS VCAM-1 and ICAM-1 expression in mesenteric microvessels increased as a result of decreased wall shear stress in stress state following internal capsule hemorrhage, and then further shear stress change from interaction of enhanced production of CAMs and leukocytes created a vicious cycle of leukocytes margination, adhesion, and transmigration that could ultimately result in stress gastrointestinal ulcer.
